Description

Technical Field

[0001] The utility model belongs to the technical field of building floor slab construction, and in particular relates to a calcium silicate board combined steel truss floor slab structure. Background Art

[0002] Currently, most of the non-disassembly formwork on the market are steel truss floor decking plates, which are made by welding the welded steel trusses and the pressed galvanized formwork into one by a formwork spot welding machine. Among them, the galvanized formwork does not need to be removed after the floor construction is completed and can be used directly as a suspended ceiling. However, this type of floor decking plate still has some difficult-to-overcome defects during the construction process.

[0003] For buildings with ceiling requirements, such as residences, office buildings and exhibition halls, since most residences do not have ceilings in advance, secondary ceiling construction is usually carried out during subsequent decoration. During construction, only plastering is required on the ceiling. At this time, if galvanized formwork is used, it is necessary to manually destroy the welding points between the steel truss and the galvanized formwork to remove the galvanized formwork used to support the cast-in-place concrete. The removed formwork is severely damaged in the process of destroying the welding points and separating from the cast-in-place concrete and cannot be reused, which is labor-intensive and cost-intensive, and is not conducive to the overall aesthetics of the floor. Therefore, a beautiful and practical steel truss floor deck that does not require removal is needed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a calcium silicate board combined steel truss floor deck structure in view of the deficiencies in the above-mentioned prior art, which has a simple structure and a reasonable design. By arranging a first asbestos-free calcium silicate board and a second asbestos-free calcium silicate board as the bottom template, the structure is light in weight and high in strength, and the template does not need to be dismantled, thereby not destroying the overall aesthetics of the room floor. By arranging a connecting piece, it is convenient to use a steel truss to simultaneously connect the first asbestos-free calcium silicate board and the second asbestos-free calcium silicate board, thereby enhancing the integrity of the splicing.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a steel truss floor deck structure of calcium silicate board combination, characterized in that: it comprises a first asbestos-free calcium silicate board and a second asbestos-free calcium silicate board, a steel truss is arranged at the connection between the first asbestos-free calcium silicate board and the second asbestos-free calcium silicate board, and the steel truss is connected to the first asbestos-free calcium silicate board and the second asbestos-free calcium silicate board through a connecting piece;

A connecting bolt connected to the first extension part and the second extension part is penetrated through the middle of the connecting block, and grooves are provided on both sides of the bottom of the connecting block.

[0009] The above-mentioned calcium silicate board combined steel truss floor deck structure is characterized in that the bottom of the clamping groove is an arc shape, and the clamping groove is arranged along the width direction of the clamping seat.

[0010] The above-mentioned calcium silicate board combined steel truss floor deck structure is characterized in that a through hole for connecting bolts to pass through is vertically opened in the middle of the connecting block.

[0011] The above-mentioned calcium silicate board combined steel truss floor deck structure is characterized in that the two grooves are symmetrically arranged on both sides of the through hole.
