万科拉片式铝模板施工方案揭秘!4天一层,一学就会

Installation principle

First install the wall pillar template, then install the beam board and the top board template, and finally make peripheral lines and template reinforcement

When installing the template initially, you can fix φ12 steel bars on the concrete surface until the inner side of the outer angle mold is used to ensure that the template installation is aligned. All templates are installed from the corner, so that the template can keep the side stability.

Before installing the template, it is necessary to ensure that all template contact surfaces and edges have been cleaned and painted. When the corner is stable and the inner angle mold is positioned according to the positioning line positioning, the entire wall mold is installed. In order to dismantle convenience, the head of the sale should be in the inner angle mold as much as possible when the wall model is connected to the inner angle mold.

Before closing the template, you need to pull the slice in advance on the wall mold connector. At the same time, you must ensure that the contact position of the template surface on both sides of the wall should be accurate. When the exterior wall is deviated, it must be adjusted to the correct position as soon as possible. This only needs to tilt the outer wall mold slightly in one plane. If there are two directions, the vertical deviation occurs, and the two layers should be adjusted to adjust one direction. Do not try to adjust the alignment of the template by unilateral promotion.

Installation of wall pillars

Nine, template demolition

The demolition period of the template should follow the arrangement of the construction technicians and team leaders. The concrete structure should be dismantled after reaching a certain strength. The demolition of the aluminum alloy template is roughly wall -beam -plate. First, the non -load -bearing parts are disassembled, and then the weight of the weight is not affected. The demolition process is as follows:

Early -demolition system

(1) According to the “Technical Regulations for Mentor Early Delocation Construction” (DB11/694-2009), when the support pitch is 2M, when the concrete strength reaches 10MPa, it is safe and reliable to implement templates with a strong level of the floor. The support spacing of this project is 1300mm, and the plate concrete strength C30 is to meet its specification requirements. The disassembly of the support rod is determined according to the same condition for the same condition to determine the demolition time.

(2) Determination of mold demolition time

When starting and seasonal transformation, the sub -bid number is made in time to make the same conditions concrete test parts, and the number of each labeling concrete is not less than one group to 2 groups (the wall column increases by 1 group, and the beam board increases 2 groups), which are separated by the beam boards), which are separated by 2 groups), respectively. The time for demolition of templates and steel support for each part to test the strength of the concrete test parts to test the demolition time and adjust the time of demolition.

Disassembling of templates such as hanging molds, bay windows, air -conditioning boards

(1) The hanging mold (rectangular steel or wood) of the sinking parts such as the bathroom, kitchen, balcony, etc. should be cleaned immediately after removal, and bundled with iron wire according to the area to prepare the lower layer.

(2) After the suspension plate is removed and cleaned up, the surface is placed in the original position, and the surface of the board faces up.

(3) The surface of the floor is cleaned, and excess debris (wood, short steel pipes, etc.) is stacked in places (balcony) that does not affect the operation.

(4) The cover plates, inner templates, and corners of the bay windows, air conditioning boards and other parts should be demolished early and cleaned them in the original position.

Wallboard demolition

(1) Use a hammer and a crowbar to remove the nails from the seventh nail position in turn until the nails of the whole wall column are removed;

(2) Stand on the work stool surface, remove more than seventh nails with hammer and crowbar (including connecting to the floor C slot)

(1) After the wall board is uploaded, the beam template can be removed. When the bottom plate of the beam is dismantled, two people should work together. When they pry, the two hold the bottom plate of the beam and put them lightly on the ground. Do not let them fall freely and cause the template to be damaged.

(2) After removing the bottom of the beam, clean it down below the beam. LS (the yin -angle mold connected to the wall), and the small block templates such as the beam bottom, such as removal or loosening, should be connected firmly in time.

(3) When disassembling the beam side mold or wall headboard, the operation platform (iron stool) cannot be placed directly below the template. It should be deviated from 200mm-300mm. When leverage the template, grab the middle of the template in one hand, so that it will not fall. Damage, remove and clean up the front of the original position to avoid mixing.

Demolition

(1) Before the top plate is demolished, the back, the pull bolt, the beam board, etc. are uploaded, and the ground debris is cleaned and stacked by the wall, which does not affect the movement of the operation platform (iron stool). First remove the room with a large area.

(2) Disassembling the top board should start from the middle of the first row. First remove the keel component (MB) connected to this template, remove the remaining three parties, use a crowbar to pry and remove, and then extend it to both sides. Do not let it be damaged freely.

(3) Demonstration of large -scale templates is strictly prohibited when disassembling the top board. Which board should be disassembled to loosen which plate is loosened, and the large -scale templates are not allowed to be pryed, which is neither safe and damaged.

(4) The first piece of yin angle mold (SL) is difficult to dismantle. First, use a hammer to lightly vibrate to break away from the surface of the concrete, and then insert it into the SL hole with a special long crowbar. The difficulty of removal of the template, as long as it ensures that the surface is cleaned during installation, apply the module evenly to control the demolition time, and it is relatively smooth when disassembling the mold.

(5) The support of the top board and beams is strictly forbidden to loosen and remove. In the template engineering construction plan, three sets of support systems are generally configured, and the support for installation must be dismantled at the lower floor.

万科拉片式铝模板施工方案揭秘!4天一层,一学就会

(2) Template installation quality requirements

(3) The quality requirements of concrete construction after demolition

Template quality assurance measure

(1) Ensure that the template has sufficient stiffness, carrying capacity and stability. The various template series we choose are a mature template engineering series, which can ensure that the quality of the construction finished product meets the current reinforced concrete quality standards. For non -series template projects used in individual parts, the technical personnel are designed and calculated before they can be used.

(2) Strictly control the quality of the template processing, and require the quality of the template to make the quality of the template compared with the current national specifications, and send a special person to check the template products.

(3) The assembly and installation process should be selected with qualified aluminum alloy templates and qualified accessories to ensure the safety of the template and the reliability of assembly.

(4) After completing the assembly and installation templates, first of all, the workers must conduct self -inspection. After the self -inspection is qualified, the next process can be performed after the corresponding quality inspector inspection and recognition.

(5) The template demolition time must meet the concrete strength of the standard requirements.

(6) Precautions for template use:

6.1 Templates should be managed by number management, which should be sorted and stacked for easy use.

6.2 When installing and removing the template, it should be gently played, not allowed to collide, and must not hit the template vigorously to avoid the template deformation.

6.3 The removal of the template should be cleaned in time. If it is found to be warp, deformation, and repairs in time, the damaged plate surface should be repaired in time.

6.4 The template for the pre -group must have a venue for storage, and the venue should be flat and solid. When the template is flattened, there must be a wooden rack. When the standing is set, the classification template frame should be set up. The template is located in the wooden cushion to ensure that the template is not distorted and does not deform. Do not pile up or stack dispersed templates and accessories on the templates that are fighting.

6.5 Walls and column templates that have been installed on the working surface are not allowed to collide when they are lifted other templates. They should not be temporarily relied before the pre -assembled template to prevent the template from deformation or vertical deviation. The plane templates that have been installed on the working surface cannot be used for temporary stacking and operating platforms to ensure the stability of the bracket and prevent the plane template elevation and peace.

Common quality problems and prevention measures

(1) Axis displacement

万科拉片式铝模板施工方案揭秘!4天一层,一学就会

1.1 Phenomenon: When the concrete is poured, it is found that the actual position of the column and the wall is shifted with the position of the building.

1.2 Analysis of the cause: The sample part is serious or the technical is unclear, and the composition fails to be in place when the template is assembled; the axis is incorrect; Do not correct it in time, causing cumulative errors; uniformly symmetrical feeding during concrete pouring, or excessive pouring height, causing a large squeezing template for side pressure.

1.3 Prevention and control measures: After the template axis is measured, organize a special person to conduct technical review and acceptance, and to support the mold after confirming it; And set up vertical vertical control lines to ensure that the level of templates and vertical positions are accurate; before concrete pouring, the template axis, brackets, top supports, and bolts should be carefully checked and reviewed in time. The height should be strictly controlled within the allowable range of the construction regulations.

(2) Equality error

2.1 Phenomenon: There are errors between the concrete structure layer elevation and embedded parts, the reserved pore standard high, and the design of the construction map.

2.2 Reasons analysis: The floor -free high control point or the control point is small, the control network cannot be closed, and the root of the vertical template is not found; the high -rise building control line is too large, and the accumulation errors are too large; The fixed solid is not paid attention to the construction method during construction; the top of the template has no standard high marker, or the construction is not based on the mark.

2.3 Prevention and control measures: The elevation of the building floor is controlled by the first floor ± 0.00 element. It is strictly forbidden to quote from layer by layer to prevent the accumulated error. When the building height exceeds 30 meters, the elevation control line should be set up. It is less than 2 for review; each floor is set up with sufficient elevation control points, and the roots of the vertical template must be found; the top of the template is set to be a standard high marker; Accurately fixed in the design location, when pouring concrete, it should be evenly poured along the surrounding layers. It is strictly forbidden to run out and vibration embedded parts templates.

(3) The seams are not strict

3.1 Phenomenon: Because there is no strict gap between the seams between the templates, there is a leaky slurry during concrete pouring, and a honeycomb and hemp surface appear on the surface of the concrete.

3.2 Reasons analysis: Do not take the sample or make mistakes. The template is not repaired in time due to the lack of corners of the corner; the template contact measure is improper;

3.3 Prevention and control measures: The embedded measures between the templates must be controlled, and the leaks must not be used to use oil felt, plastic cloth, and cement bags.

(4) Looping and rotten roots of the walls and columns

4.1 Phenomenon: In the main structure of the main structure, the corner of the wall is leaked.

4.2 Reasons analysis: The template is not cleaned up, and the surface is accompanied by cement slurry, which makes the gap at the corner of the yang; the concrete ash ratio is too large;

4.3 Prevention and control measures: The surface of the cement slurry should be cleaned up, the slump of the concrete should be strictly controlled (about 120mm), training the vibrations should be trained, and the technical personnel must be technically confined to the technicians before pouring the concrete.

(5) Wall column yang corner leakage and rotten roots

5.1 Phenomenon: The roots of the wall and the roots of the wall.

5.2 Reasons analysis: There is a gap between the feet of the surface of the wall and the roots of the wall and the pillar. The roots of the wall of the wall pillar cause the leakage of the leakage slurry; the roots of the wall pillar mold are not cleaned up and the stagnant water is not cleaned, and the roots of the slag are not found. Highness, not low, cause rotten roots; if the level is not good, the water and gray ratio is too large or too small, resulting in rotten roots.

5.3 Prevention measures: During the template installation, cleaning the mouth of the roots, remove the garbage before pouring the concrete, eliminate the water accumulation, and then block the mouth washed up, and then pour the concrete. Time, wall column concrete pouring should be poured along the height; the collapse of the concrete should be controlled within 150mm.

Concrete finished product protection

(1) Due to the low concrete strength during the dismantling of the template, special attention should be paid to the process of the tower crane material transport and artificial materials.

(2) All walls, columns, large holes, and staircases. After the mold is demolished, take protection measures to prevent the collision of the concrete corner. clean;
