Problems solved by technology

[0007] 1. Foam boards are placed at the deformation joints, but it is also difficult to remove the foam boards, and the foam boards are easy to deform, which affects the structural size
[0008] 2. Formwork is used to support the deformation joints. Although the cross-sectional size can be guaranteed in this way, it is too difficult to dismantle. In many cases, it cannot be dismantled, causing quality problems
[0009] 3. Use wooden molds to sandwich foam boards, which is an improvement compared to the previous two, but it is also quite difficult to dismantle, and the structural size is not easy to guarantee
[0010] 4. The two sides of the deformation joints are to be constructed twice, but due to the narrow space, it is impossible to avoid the difficulty of supporting and dismantling, and if there are many deformation joints, the construction period will be affected

Abstract

The invention relates to an easy-to-dismantle deformation joint form erecting method which comprises the following steps: (1) mounting first wood glue plates which are 1 to 12mm thick on the two sides of a deformation joint respectively; (2) laying a first batten which is 50mm thick at the bottom of the deformation joint; (3) sequentially placing scaffold tubes in the deformation joint until the distance between the scaffold tubes and the upper surface is smaller than 100mm; (4) arranging a second batten above the scaffold tubes. The easy-to-dismantle deformation joint form erecting method has the beneficial effects that (1) easiness for dismantling is achieved; (2) such a combination is stiff enough, and the structural dimensions on the two sides of the deformation joints can be ensured; (3) the adopted materials are common for construction, and can be recycled; (4) the two sides of the deformation joints are simultaneously constructed, so that the construction speed is increased.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to an easy-to-remove deformation joint formwork support method. Background technique [0002] Deformation joints can be divided into three types: expansion joints, settlement joints, and seismic joints. [0003] Expansion joints: Building components will expand and shrink due to changes in temperature and humidity. For this reason, vertical gaps are usually set at appropriate parts of the building, and the wall, floor, roof and other components of the house are disconnected from the foundation, and the building is separated into several independent parts. For the seams set up to overcome the excessive temperature difference, the foundation may not be disconnected, and the structure is disconnected from the top surface of the foundation to the roof. [0004] Seismic joints: The joints set up to make the building more regular and beneficial to the struct...
