Description

Technical Field

[0001] The invention relates to the field of building construction, in particular to an assembled prefabricated brick membrane. Background Art

[0002] In general housing construction projects, the pile foundation's pedestal and waterproofing board mostly adopt the high-slab form of beam-slab raft foundation, which requires a large number of templates to be set up in the foundation part to ensure the formation of the pedestal, pedestal beam and ground beam. Conventional construction methods mostly use brick membrane as the template of the foundation part. The brick membrane is made of standard bricks into a template. After it has a certain strength, concrete pouring is carried out. However, the construction period of a large number of brick membrane masonry is long, the labor input is large, and there are many objective factors affecting the construction period, which makes it difficult to control the construction period and cost. Summary of the invention

[0003] The purpose of the present invention is to provide an assembled prefabricated brick membrane, which can be directly assembled during construction without cement masonry, thus saving time and labor.

[0004] The object of the present invention is achieved through the following technical scheme: an assembled prefabricated brick membrane, which is spliced by prefabricated panels, and the outer side edges of the prefabricated panels are provided with flanges. Adjacent prefabricated panels are fixed by bolt locking members or mortise and tenon structures, and the bolt locking members are passed through and fixed between two adjacent flanges.

[0005] Compared with the prior art, the advantages of the present invention are:

[0006] 1. The present invention replaces the brick membrane of traditional brick masonry, saving a large amount of construction bricks and cement, being energy-saving and environmentally friendly, and is assembled through prefabricated panels, which can be used immediately after installation without waiting for the masonry cement to solidify, thus shortening the construction period.

[0007] 2. The outer side edge of the prefabricated panel is provided with a convex edge, which not only increases the strength of the entire prefabricated panel, but also can be used as a splicing part. The bolt locking piece is passed through and fixed between two adjacent convex edges, so that the prefabricated panel can be quickly assembled, saving construction time and improving work efficiency by three to five times.

[0008] 3. Corner protectors are provided at the corners of the brick membrane to prevent the corners from being squeezed and deformed due to pouring.

[0009] 4. Side wall protection pieces are provided at the vertical joints of the brick membrane side walls, which can prevent the vertical joints from being squeezed and deformed due to pouring.

[0010] 5. The present invention is provided with a height compensation plate. When the height specification of the prefabricated panels cannot be spliced to the designed height, the height compensation plate can be used for compensation.

[0011] 6. The present invention is also provided with a sub-platform barrier. When the two bearing platforms are relatively close to each other, only one brick formwork can be assembled, and the brick formwork can be divided into two independent pouring grooves through the sub-platform barrier, effectively improving the construction efficiency.

[0032] Corner protection pieces 4 are provided at the corners of the brick membrane.

[0033] In one embodiment, the corner protection member 4 includes a horizontal base 4-1 and a vertical bending plate 4-2 disposed on the horizontal base 4-1;

[0034] The horizontal base 4-1 is fixed to the lower base surface by a bolt locking member 2, and the vertical bending plate 4-2 thereon is attached to the corners of the brick membrane. The vertical bending plate 4-2 fits the corners of the brick membrane and can be fixed to the prefabricated plate 1 by a bolt locking member 2 to increase stability (see Figure 9 ).

[0035] In another embodiment, the corner protection member 4 includes a vertical positioning tube 4-3, the side wall of the vertical positioning tube 4-3 is provided with a notch 4-4 that fits with the edge of the brick membrane, and the vertical positioning tube 4-3 is provided with a vertical landfill groove 4-5 (seeFigure 10 )。
