Description

Mounting bracket for prefabricated component, prefabricated wall with the bracket and installation method thereof

technical field

The invention relates to the field of building prefabricated components in building construction, in particular to a prefabricated component installation bracket, a prefabricated wall body containing the bracket and an installation method thereof.

Background technique

In order to improve construction efficiency, many buildings are built with prefabricated modules. Prefabricated components such as exterior wall panels, interior wall panels, floor slabs, beams, stairs, columns, etc. are prepared in advance, and then transported to the construction site for splicing and construction at the construction site.

During the construction process, multiple support mechanisms are supported on the ground, and prefabricated floor slabs are built on the upper end of the support mechanisms. After the first-floor prefabricated wall panels are hoisted to the designated position, a connection cavity is formed between the prefabricated wall panels and the two prefabricated floor slabs. Adjust the levelness and height of the prefabricated wall panels. After the adjustment is completed, pour concrete into the connecting cavity to complete the construction of the prefabricated wall panels and prefabricated floor slabs.

When the upper layer of prefabricated wall panels is installed, it is usually necessary to install a support at the lower end thereof to support the upper layer of prefabricated wall panels. The Chinese patent with authorized notification number CN205369690U discloses a prefabricated building wall panel. As shown in Figure 1, the prefabricated wall body includes a first prefabricated wall panel 7, a second prefabricated wall panel 8, a first prefabricated wall panel 7 and a prefabricated wall panel. A support frame is installed between the second prefabricated wall panels 8, and the support frame includes an upper support plate 1 bolted and fixed with the second prefabricated wall panel 8, a lower support plate 2 bolted and fixed with the first prefabricated wall panel 7, and an upper support plate 1 and the lower support plate 2 are connected with a plurality of support columns 101 to realize temporary positioning of the upper prefabricated wall panel.

However, in the actual construction process, the interval between the first prefabricated wall panel 7 and the second prefabricated wall panel 8 is adjusted accordingly according to the thickness of the prefabricated floor slab 9, while the upper support plate 1 and the lower support plate in the existing support frame The distance between 2 is fixed, and cannot be adjusted with the thickness of the prefabricated floor slab 9, and needs to be customized according to different thicknesses of the prefabricated floor slab 9, which is cumbersome.

Contents of the invention

The object of the present invention is to provide a mounting bracket for prefabricated components, the height of which can be adjusted with prefabricated floor slabs of different thicknesses, and the application range is wider.

The above-mentioned technical purpose of the present invention is achieved by the following technical solutions: a mounting bracket for prefabricated components, including an upper support plate and a lower support plate oppositely arranged, a number of upper adjustment columns are fixed to the lower end of the upper support plate, and the lower support plate The upper end of the upper adjustment column is fixed to the lower adjustment column opposite to the upper adjustment column. The upper adjustment column is provided with a positive thread, and the lower adjustment column is provided with a reverse thread. The upper adjustment column and the lower adjustment column are threaded to connect the sleeve.
