Problems solved by technology

The construction of deformation joints has plagued many construction projects. Many projects using wooden formwork have to purchase aluminum formwork for laying deformation joints, which increases the cost of the project.
Or the random laying of formwork in the construction of deformation joints leads to difficulty in expansion and removal of formwork, and it is difficult to guarantee the quality of the project
[0003] Therefore, there are above-mentioned inconveniences and problems in the known deformation joint template laying

Embodiment 1

[0029] The deformation joint formwork construction method of the present invention is applicable to wall structure expansion joints, comprising the following steps:

[0030] a. Calculate the wall area at the construction joints according to the construction drawings, and at the same time determine the use of wood formwork according to the formwork material supplied on site; the material of the wood formwork is plywood 6 with a thickness of 12mm.

[0031] b. Formwork production inside the wall: please refer to figure 1 , figure 1 It is a structural schematic diagram of the formwork inside the wall according to the embodiment of the present invention. According to the height and width of the wall, lay the wooden formwork of the corresponding area on the ground, use 13 pieces of 40×90mm wooden squares 5 whose length is equal to the height of the wall, and lay the wooden squares vertically and parallel to each other on the wooden formwork. 200mm, 5 Ф48mm double steel pipes are a...

Embodiment 2

[0037] image 3 It is a schematic diagram of the installation of the deformation joint formwork according to the embodiment of the present invention, and it is also a schematic diagram of batch pouring on both sides when the distance between the deformation joints is too small.

[0038] When the distance between the deformation joints is too small, the installation of the deformation joint formwork adopts batch casting of units on both sides, that is, after the strength of the first poured side meets the requirements, the formwork is removed and the other side is poured.

[0039] The present invention has substantive features and significant technical progress. The deformation joint formwork construction method of the present invention is easy to manufacture and can be produced using on-site materials without the need to purchase other materials. The integral laying is not only convenient for installation, It can also be dismantled as a whole, and the operating efficiency is g...

Abstract

A deformation joint formwork erection construction method is suitable for wall structure expansion joints, and is characterized by including the steps that a, the wall area at a construction joint isworked out according to a construction drawing, and meanwhile it is determined that timber formworks are used according to formwork materials supplied on site; b, the wall inner formwork is manufactured; c, the wall outer formwork is manufactured; d, formwork reinforcement is carried out; e, formwork installation is carried out, wherein the whole reinforced deformation joint formwork is hoisted tothe deformation joint through a tower crane and then is installed and fixed at the deformation joint by workers. The deformation joint formwork erection construction method has the advantages that the deformation joint formwork is simple in structure and convenient to manufacture, the overall laying mode is adopted for the deformation joint formwork, reinforcement measures for the deformation joint formwork are effective, the phenomena of formwork swelling, bottom grout leaking and the like will not occur, the construction quality is improved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a method for laying concrete formwork in construction engineering, in particular to a construction method for supporting formwork with deformation joints. Background technique [0002] Deformation joints in construction engineering are the general term for expansion joints, settlement joints and anti-seismic joints. Buildings often deform under the action of external factors, resulting in cracking or even destruction. Deformation joints are structural joints reserved for this situation. The construction of deformation joints has plagued many construction projects. Many projects using wooden formwork have to purchase aluminum formwork for laying deformation joints, which increases the cost of the project. Or the random laying of formwork in the construction of deformation joints will lead to difficulty in expansion and removal of formwork, and it is difficult to guarantee the quality of the project. [0003] Therefore there are...
