[0002] In conventional building foundation brick membrane projects, especially in the foundation construction process of group and high-rise residential projects, the masonry work of brick membrane is very large. Usually, brick membrane is used for the side mold of the foundation, and the surface mortar is painted after the masonry construction. The construction operation is relatively cumbersome, the wet operation workload is large, the construction efficiency is low, and more manpower and material resources are required. In addition, the compressive strength of the brick mold is not easy to meet the design requirements, and the painted surface layer needs to wait for time to dry, and the moisture content is reduced to the specification requirements before waterproofing construction can be carried out. Utility Model Content

[0003] The technical problem to be solved by the utility model is that, in view of the shortcomings of complicated construction operation, low efficiency and long construction time of building foundation brick membrane, the utility model provides a building foundation template installation structure which accelerates the construction speed of the building foundation template, has high construction efficiency and low comprehensive cost.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A building foundation template installation structure comprises a plurality of templates which are sequentially spliced, wherein the templates are ALC boards, the lower part of the templates is buried in the soil layer, and adjacent templates are connected by fixing plates.

[0006] The utility model uses a building foundation template assembled by ALC boards (lightweight boards) to replace the original building foundation brick membrane, which is simple to construct, highly operable, low in comprehensive cost, fast in construction speed and high in labor efficiency.

[0007] Furthermore, the fixing plate includes a straight-line fixing plate and an L-shaped fixing plate, the straight-line fixing plate is installed at the plane joint of the template, and the L-shaped fixing plate is installed at the corner joint of the template.

[0008] Furthermore, the joints between adjacent formworks are repaired and leveled with anti-cracking and waterproof mortar to ensure the levelness of the entire side of the formwork.

[0009] Furthermore, the depth of the template buried in the soil layer is not less than 300 mm.

[0010] Furthermore, the spacing between the fixing plates in the height direction of the ALC board is no more than 80 cm.

[0011] Furthermore, the formwork is reinforced with step-by-step tightening, steel bars or steel pipes to ensure the overall stability of the formwork.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The ALC board (lightweight board) used in the utility model is produced by the factory, with uniform board specifications and a flat surface. The flatness of the boards after assembly can be controlled within 5 mm, which fully meets the requirements of the waterproof base layer. At the same time, the surface layer of the boards is free of plastering, which greatly reduces on-site wet operations and avoids quality problems such as hollowing of waterproof membranes due to the moisture content of the base layer not meeting the requirements. The overall visual quality of the lightweight boards is good.

[0014] 2. The utility model adopts lightweight boards to assemble the formwork. Compared with the traditional brick membrane construction process, the strength of the lightweight boards is higher than that of masonry, which reduces the labor intensity of workers. The construction is simple, the operability is strong, the comprehensive cost is low, and the labor efficiency is high. It can be promoted and used in buildings with foundation side formwork.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] See also Figure 1 - Figure 5 An embodiment of the building foundation template installation structure of the utility model includes an ALC board 4, a straight-shaped fixing plate 5, an L-shaped fixing plate 2, a steel nail 3, a soil layer 1, and an anti-cracking and waterproof mortar 6.

[0027] ALC panels 4, i.e. lightweight panels, are customized by the factory and installed on the construction site. Multiple ALC panels 4 are sequentially spliced ​​into the foundation side formwork, and the lower part of the ALC panels 4 is buried in the soil layer 1, with a depth of not less than 300 mm, and adjacent ALC panels 4 are connected with fixing plates and steel nails 3.

[0028] The fixing plate includes a straight-line fixing plate 5 and an L-shaped fixing plate 2 . The straight-line fixing plate 5 is installed at the plane joint of the ALC board 4 , and the L-shaped fixing plate 2 is installed at the corner joint of the ALC board 4 .

[0029] In order to ensure the flatness of the entire side of the building foundation template installation structure, the joints of adjacent ALC boards 4 are repaired and leveled with anti-crack waterproof mortar 6.

[0030] In order to ensure the overall stability of the building foundation template installation structure, the ALC board 4 is reinforced with step-by-step tightening, steel bars or steel pipes.

[0031] During the specific construction of the utility model, the surveyor lays out the foundation edge line and determines the installation position of the ALC board 4. The control line uses a thin rope. According to the layout position, a guide groove is excavated in the foundation pit of the building foundation. The excavation width of the guide groove is about 30cm and the depth is about 20cm. The excavation of the guide groove should be carried out as the ALC board 4 is assembled. According to the design drawings, the bottom elevation of the guide groove is excavated to 30cm below the design elevation, and the bottom elevation of the guide groove is H-30cm. The guide groove should be excavated as the plate is installed to prevent problems such as the change of the guide groove elevation due to process stoppage, soft soil, and rainwater soaking. After the excavation is completed, the bottom of the groove is patted with a shovel to effectively control the flatness and density of the base groove. After the ALC board 4 is installed, the original soil is used to backfill the guide groove, which is patted with a shovel and compacted with a small tamping machine with appropriate watering. After the surface of the base and the wallboard is cleaned, the ALC board 4 is aligned with the reference line and the rear board is erected. During installation, make sure that the tenons and mortises of the ALC board 4 are connected to each other. Two people straighten the ALC board 4 into place. After it is in place, one person holds it steady on one side to align it accurately. One person pries up the ALC board 4 with a crowbar, squeezes it while prying, and moves the ALC board 4 within the reference line by moving the crowbar. When the reference line is aligned, one person holds the ALC board 4. After preliminary adjustment, the other person picks up the prepared fixing plate and hammers the steel nail 3 into the ALC board 4. The adjacent ALC boards 4 are fixed with a straight-line fixing plate 5. The fixing plate and the ALC board 4 are fixed with steel nails. The spacing between the fixing plates is not more than 80cm. The corners are fixed with L-shaped fixing plates 2. After installation, adjust the verticality, flatness and straightness of the formed wallboard. Before the board joints are processed, the joints should be sprinkled with water to moisten them. The anti-cracking waterproof mortar 6 is used to point the board joints with a width of about 10cm. After pointing, the flatness of the board should meet the quality requirements of the waterproof base. This technology is easy to construct, highly operable, has low overall cost and high labor efficiency, and is worthy of promotion and use in foundation side formwork construction.
