Description

Technical Field

[0001] The utility model relates to the technical field of truss plate construction, in particular to a detachable steel bar truss plate and wall aluminum formwork combined support system. Background Art

[0002] In recent years, the country has vigorously advocated the development of prefabricated buildings, and steel truss floor decking is an important component of prefabricated buildings. The steel truss floor decking is a building product in which the load-bearing steel bars in the floor slab are welded into steel trusses in the factory, and the steel trusses are fixedly connected to the bottom formwork to form an integrated bottom formwork and the load-bearing steel bars. In order to enable the bottom formwork to be recycled after pouring, steel truss floor decking with disassembled bottom formwork has appeared in the prior art, such as a steel truss floor decking with a detachable bottom formwork with publication number CN109469240A, a detachable bottom-mode steel truss floor decking with publication number CN105317145A, etc. After the concrete is poured and the concrete reaches the demolding strength, the bottom formwork can be removed for repeated recycling.

[0003] Conventional truss plate construction often adopts a wooden formwork support system, which usually uses steel pipe fasteners (or wheel buckles, bowl mouths, etc.) and primary and secondary keels to form a support system. The primary and secondary keels are usually made of steel pipes, square steels, wooden squares and other materials. The truss plate bottom formwork and wall formwork are both wooden formworks, which are combined with steel nails to form a common main structure formwork system. In conventional support construction, the erection of primary and secondary keels is time-consuming and labor-intensive, with poor rigidity, dense arrangement and low construction efficiency. At the same time, due to the poor support of the primary and secondary keels, the width of the truss plate supported on the upper side is not easy to exceed 600mm, the width is relatively narrow, there are many joints, the top plate joint forming effect is poor, and the flatness after concrete pouring is poor. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a detachable steel truss plate and wall aluminum formwork combined support system which does not require the erection of primary and secondary keels, has high construction efficiency and good support effect.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A detachable steel bar truss plate and wall aluminum formwork combined support system, comprising a truss plate, a beam formwork, a wall formwork and a support column, wherein a plurality of groups of mutually connected truss support assemblies are arranged on the lower side of the truss plate, and a beam side support assembly is arranged at intervals on the lower side of the beam formwork, the truss support assembly comprises a first support plate with a rectangular structure and a second support plate with a long strip structure, the upper edges of the beam formwork and the wall formwork are both provided with inverted L-shaped connecting wings, and the end of the second support plate is connected to the side edge of the first support plate or the outer edge of the horizontal part of the inverted L-shaped connecting wing; the joint between the truss plate and the truss plate is located on the second support plate; the support column comprises a first support column and a second support column, the first support column is arranged on the lower side of the first support plate, and the second support column is arranged on the lower side of the beam formwork; the beam side support assembly comprises an oblique support rod, each second support column is provided with two oblique support rods, the two oblique support rods are arranged in an inverted eight-shaped shape, the lower overlapping position is connected and fixed to the second support column, and the upper part is respectively located on both sides of the beam formwork, and is connected and fixed to the second support plates corresponding to the two sides of the beam formwork.

After being connected, the first support plate and the second support plate form a tic-tac-toe structure, which together support the truss plate, solving the problem that in the traditional support structure, the primary and secondary keels are not on the same plane, the supporting force is weakened to a certain extent during transmission, so that the supporting rigidity is insufficient, and the width of the truss plate supported thereon is not easy to exceed 600mm. By using the new support truss plate, the width of the truss plate can be set at 800mm-120mm;

[0009] 2. The first support plate and the second support plate are located on the same plane, which makes the support flatness stronger and improves the quality of the top plate joint forming;

[0010] 3. The second support plate also supports the beam formwork and the wall formwork. Together with two inverted eight-shaped diagonal braces, it provides reverse support for the beam formwork.
