Detailed Description
The construction method of the rear plug piece type variable cross-section aluminum alloy template comprises the following steps:
1. wall formwork
And (3) finding out the required templates according to the numbers, cleaning, coating an oily template isolation agent, placing the templates at the corresponding positions of the wall, rechecking the concrete elevation of the wall foot, penetrating a sleeve and a high-strength bolt, fixing the wall template and the skirting board by using pins in sequence, and fixing the wall template by using the pins. After the wall formwork is installed, the vertical line is hung to detect the verticality of the wall formwork, and the verticality is adjusted to be within a standard range.
2. Template for mounting beam plate
And after the wall column template is installed and rechecked, the beam slab template is installed. And installing a beam bottom template and a template supporting upright rod according to the requirements of design drawing according to the position and the span of the beam. The concrete operation key points are that the beam bottom formwork is supported on a beam notch reserved in the wall body formwork, and the beam bottom support vertical rod is installed along with the beam bottom formwork, so that the reliable connection of the beam bottom formwork is ensured. According to the design, the elevation of the bottom beam template is adjusted through the elevation of the bottom support of the vertical rod, then the side beam mold is installed, and the verticality of the side mold is corrected. And simultaneously, installing an angle die between the wall column and the top plate, and after the angle die is installed, installing a top plate cross beam, a top plate template and a supporting vertical rod.
After the installation is finished, the leveller is used for detecting the flatness of the beam plate template again, and the uneven position enables the levelness of the template to be within an allowable range by adjusting the bottom supports of the vertical rods.
3. Plug sheet for mounting wall and beam slab formwork
By taking 26-storey residential buildings as an example, the cross-sectional dimension of the wall bodies of 1-10 storeys is 200mm, the cross-sectional dimension of the wall bodies of 11-18 storeys is 180mm, and the cross-sectional dimension of the wall bodies of 19-26 storeys is 160mm, which relates to the change of the cross-sectional dimension of the wall bodies. With the progress of construction progress, the section size of the wall body is gradually reduced, the clearance size of a room is increased, and therefore the configuration size of the aluminum formwork needs to be changed, and the aluminum formwork is a sizing formwork. The problem of cross-sectional dimension variation is solved by adding a plug sheet.
The preparation of the plug sheet: based on aluminum materials, the thickness of the aluminum die is 10mm, the width of the aluminum die is equal to the width of the edge of the aluminum die, and the plug sheet and the pin hole of the edge are penetrated into corresponding pin holes at the same positions. The length is made to the designed clear height (clear width) of the room. The processing error is controlled within the range of +/-3 mm.
Installing a plug piece: the templates of the variable cross-section wall body are still assembled according to the original serial numbers, the cross-sectional dimension of the wall body is reduced by 20mm, the distance between the templates on the two sides of the wall body is reduced by 20mm, and the template wall connected with the templates on the two sides of the wall body is lengthened by 20mm, so that two processed and manufactured plug sheet pin holes are outwards placed between the two templates on the template wall, aligned with the pin holes, provided with pins and fixed plug sheets. The difficult problem of changing the size of the cross section of the wall is successfully solved. As shown in fig. 5, when the formwork on one side of the wall moves (the solid line moves to the dotted line position), the distance between the formwork on the two sides of the wall is reduced, and the plug sheet 1 needs to be plugged into the formwork wall 2.
After the wall formwork is provided with the standard formwork, the plug sheets are inserted into the gaps between the formworks from outside to inside and are firmly fixed by pins, and the installation is completed.
After the standard template of the top plate is installed in place, the plug piece is inserted into the gap of the beam plate from bottom to top and is firmly fixed by the pin, and the installation of the plug piece is completed.
4. Template correction fixing
And after the templates are installed, checking the flatness and the verticality of all the wall columns, beams and plates. And after the checking is finished, adding a specially-made double-square steel back ridge on the wall column template and fixing the wall column template by using a high-strength bolt.
5. Pouring of concrete
After the correction and fixation, the gap condition of each interface is checked, and a foam plastic strip is required to be pasted to prevent slurry leakage if the gap condition exceeds the specified requirement. And after the treatment is finished, carrying out hidden acceptance of reinforcing steel bars and the like, and then pouring concrete. When the concrete of the floor is poured, a special template worker is arranged to keep watch on the template under the operation floor so as to solve the sudden problems of template sinking, template explosion and the like during the concrete pouring.
6. Form dismantling and transporting
And when the strength of the concrete reaches the standard form removal time, removing the form, and manually transporting the form to the upper layer through a material conveying port reserved on the floor slab.
The application of the construction technology provides valuable experience for the construction of the aluminum alloy formwork variable-section wall and the construction of similar projects. The aluminum alloy plug piece is adopted, the difficult problem of variable cross section construction of the aluminum alloy template is solved, the delay of the construction period caused by replacing plates with the traditional aluminum template is avoided, the construction quality and safety are guaranteed, meanwhile, the working efficiency is improved, the construction period is shortened, the engineering quality and safety are effectively guaranteed, the process construction has positive popularization significance, and the process is subjected to consistent approval and high evaluation of design units, supervision units and government related departments. Has remarkable social benefit.
