Description

Technical Field

[0001] This application relates to the technical field of prefabricated buildings, and particularly to a prefabricated non-removable floor slab formwork. Background Art

[0002] Existing floor slabs are generally cast with reinforced concrete. For the convenience of construction, some of the steel bars in the floor slab are usually made into steel bar trusses. The steel bar truss includes an upper chord steel bar and two lower chord steel bars. The lower chord steel bars are welded and fixed to the upper chord steel bar through web bars. The bottom formwork is connected to the lower chord steel bars through bolts and special snap devices. The steel bar truss and the bottom formwork are combined to form a detachable bottom formwork steel bar truss floor slab formwork. During construction, multiple detachable bottom formwork steel bar truss floor slab formworks are first assembled together, and then concrete is directly poured. After the reinforced concrete solidifies, the bottom formwork is disassembled and recycled for reuse.

[0003] Among them, the utility model patent with the publication number CN217811855U discloses a prefabricated non-removable floor slab formwork. However, when the above patent is used, there are still certain deficiencies. Its non-removable bottom layer and steel bar truss are integrally installed and assembled together, and cannot be disassembled and assembled. During transportation, the volume is relatively large, which is not convenient for the transportation and transfer of the prefabricated floor slab formwork. Therefore, we provide a prefabricated non-removable floor slab formwork to solve the above problems. Utility Model Content

A support rod is clamped on the inner wall of each installation groove. A set of assembly holes are formed on the upper surface of each support rod. A set of assembly bolts are fixedly embedded in the inner bottom wall of each installation groove. The top end of each assembly bolt passes through the assembly hole and is threadedly connected with an installation nut. A set of triangular steel bar trusses are fixedly connected to the upper surface of the set of support rods. Two diagonal connecting bars are fixedly connected to the outer surface of each triangular steel bar truss.

[0007] Preferably, a set of reinforcing ribs are fixedly embedded in the floor slab bottom plate, and the reinforcing ribs are made of steel wire.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To make the objectives, technical solutions, and advantages of this application more clear, the following will clearly and completely describe the technical solutions of this application in combination with specific embodiments of this application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope of protection of this application.

[0021] The following will detail the technical solutions provided by each embodiment of this application in combination with the drawings.

[0022] Please refer to Figures 1-4 , this utility model provides a technical solution for an assembled non-removable floor formwork:

[0023] An assembled non-removable floor formwork includes a floor formwork bottom plate 1. A set of installation grooves 2 are opened on the upper surface of the floor formwork bottom plate 1. A support rod 3 is clamped on the inner wall of each installation groove 2. A set of assembly holes 12 are opened on the upper surface of each support rod 3. A set of assembly bolts 10 are fixedly embedded on the inner bottom wall of each installation groove 2. The top end of each assembly bolt 10 penetrates through the assembly hole 12 and is threadedly connected with an installation nut 9. A set of triangular steel bar trusses 4 are fixedly connected to the upper surface of a set of support rods 3. Two diagonal connecting bars 5 are fixedly connected to the outer surface of each triangular steel bar truss 4; specifically, through the arranged assembly holes 12, assembly bolts 10, and installation nuts 9, the bolt assembly installation of the floor formwork bottom plate 1 and the triangular steel bar truss 4 can be realized, facilitating the rapid installation operation of the floor formwork.

[0024] In this embodiment, a set of reinforcing ribs 7 are fixedly embedded in the floor formwork bottom plate 1. The reinforcing ribs 7 are made of steel wire; a tensile fiber wire layer 11 is fixedly connected to the bottom surface of the floor formwork bottom plate 1; specifically, through the arranged reinforcing ribs 7 and tensile fiber wire layer 11, the overall compressive strength of the floor formwork bottom plate 1 can be effectively increased, facilitating the stable use of the assembled floor formwork.

[0025] In this embodiment, two sets of hanging rings 6 are fixedly embedded on the upper surface of the floor formwork bottom plate 1. The hanging rings 6 are made of metal; a set of horizontal ribs 8 are fixedly connected to the upper surface of a set of triangular steel bar trusses 4. The set of horizontal ribs 8 are arranged at equal intervals; specifically, the floor formwork bottom plate 1 can be conveniently lifted through the hanging rings 6, facilitating the installation and use of this device. By arranging the horizontal ribs 8, the overall strength of the triangular steel bar trusses 4 can be increased, facilitating the stable use of this device.

[0026] Working principle: When the prefabricated non-removable floor formwork is in use, the user first assembles and welds the triangular steel bar truss 4 and the support rod 3 in the factory, and welds the transverse bars 8. Then, the floor formwork bottom plate 1 and the assembled and welded triangular steel bar truss 4 are loaded separately onto the vehicle for transportation. After transporting to the construction site, the triangular steel bar truss 4 is lifted, so that the assembly holes 12 are sleeved on the assembly bolts 10, and the installation nuts 9 are threadedly connected to achieve on-site assembly of the floor formwork. Then, it is hung on the hanging ring 6 through the hoisting equipment, and the assembled floor formwork is hoisted to the designated position of the building, and then concrete is poured.
