[0027] The application will be further described below in conjunction with the drawings and specific embodiments. It should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments without conflict.

[0028] The application refers to Figures 1-4 As shown, it comprises a bottom template 1, connecting pieces 2 fixedly arranged on the bottom template 1 and used for supporting and fixing steel bars 4, and purlins 3 arranged on the bottom template 1 in a detachable manner through connecting structures. All the purlins 3 and all the connecting pieces 2 are arranged on opposite two surfaces of the bottom template 1 respectively. In this embodiment, the above-mentioned arrangement is used in construction. First, the surface of the bottom template 1 with the connecting pieces 2 is taken as the upper surface and laid in the floor. At this time, the purlins 3 of the bottom template 1 can support the bottom template 1 to prevent it from being bent and deformed. Then, workers can lay connecting pipes and lines on the upper surface (at this time, the upper surface is used for erecting the steel bars 4, and the pipes and lines are laid more conveniently, improving the construction efficiency). After completion, the steel bars 4 are installed and fixed on the connecting pieces 2 and the concrete is poured (the concrete is poured only on the upper surface provided with the connecting pieces 2). Finally, the purlins 3 are detached and recycled. Through the above-mentioned construction method, in the case of forming a firm and stable floor, not only is the construction more convenient and fast, improving the construction efficiency, but also the steel bar 4 truss and the purlin 3 can be recycled, reducing the amount of steel material and greatly reducing the cost investment.

[0029] The connecting structure in this embodiment is a bolt 6, and the purlin 3 is arranged on the bottom template 1 in a detachable manner through the bolt 6. Through the use of the bolt 6 for connection and fixation, not only is the material convenient to obtain, but also workers can simply and quickly realize the disassembly and assembly between the purlin 3 and the bottom template 1, reducing the processing difficulty and improving the construction efficiency. In other embodiments, the connecting structure can also be a buckle connecting structure, such as a clamping groove. When installed, the purlin 3 is slid into the clamping groove and detachably fixed on the bottom template 1.

[0030] In the production of the embodiment, the various parts can be prepared first and then assembled. First, the connecting piece 2 is fixed to the bottom template 1 by a countersunk screw. Then, the bottom template 1 is turned over, and the purlin 3 is detachably fixed to the bottom template 1 by a bolt 6. At this time, the combined floor support plate is formed and can be directly fixed to the floor for construction. In order to improve the stability of the connection, the connecting piece 2 and the purlin 3 are symmetrically arranged on the two opposite surfaces of the bottom template 1. When the bolt 6 is installed, it passes through the purlin 3, the bottom template 1, and the connecting piece 2 in sequence, so that the overall connection is more stable and firm. At the same time, the bolt 6 does not pass through the connecting piece 2, preventing the bolt 6 from being unable to be unscrewed after pouring concrete. Preferably, the bottom template 1 in the embodiment is a fiber cement board, a cement-based prefabricated board, or a bamboo plywood.

[0031] In the embodiment, the connecting piece 2 is provided in multiple numbers and is arranged on the bottom template 1 at intervals along the same straight line. In the embodiment, the main function of the connecting piece 2 is to provide support and fixation for the steel bar 4. Therefore, after multiple connecting pieces 2 are arranged, the steel bar 4 can be more stably erected on the bottom template 1, without affecting the laid pipes and wires, and can also provide stiffness to the concrete, improving the stability of the floor after construction. Specifically, the connecting pieces 2 can be arranged in an array to ensure that the erection direction of the steel bar 4 is more diversified.

[0032] In the embodiment, the connecting piece 2 is provided with a buckle slot for fixing the steel bar 4. Through the fixing mode of the buckle slot, the steel bar 4 can be more stably fixed on the connecting piece 2 and will not loosen, avoiding affecting the construction. At the same time, the buckle slot in combination with the multiple connecting pieces 2 can ensure the straightness and stability of the whole straight steel bar 4 during erection, making the formed floor more level and firm.

[0033] Specifically, the buckle slot includes a first buckle slot for buckling the steel bar 4 laid along the length direction of the bottom template 1, a second buckle slot for buckling the steel bar 4 laid along the width direction of the bottom template 1, and a third buckle slot for buckling the steel bar 4 laid along the diagonal direction of the bottom template 1. Through the arrangement of the three buckle slots, the erection direction of the steel bar 4 also has horizontal, vertical, and diagonal directions, which can be adjusted according to the actual situation on site. In other embodiments, only one or any two of the above three buckle slots can be arranged.

[0034] Similarly, in the embodiment, the purlin 3 is provided in multiple numbers and is arranged on the bottom template 1 at intervals along the same direction. Through the arrangement of multiple purlins 3, the bottom template 1 can be better formed to prevent the bottom template 1 from deforming. At the same time, the bottom template 1 can increase its own specifications under the premise of ensuring construction safety, reducing the splicing process during construction.

[0035] Specifically, in this embodiment, multiple purlins 3 are laid along the length, width, or diagonal direction of the bottom formwork 1. By fixing multiple purlins 3 in the same direction, more stable support can be provided to the bottom formwork 1, while also reducing assembly time. In other embodiments, purlins 3 can be simultaneously installed in two of the above three directions, or even in all three directions, to maximize support for the bottom formwork 1 and ensure construction safety.

[0036] In this embodiment, the composite floor deck also includes a leveling component 5 for leveling the bottom formwork 1 when two adjacent bottom formwork 1s are spliced. One end of the leveling component 5 is rotatably mounted on the bottom formwork 1, and the other end is a free end. The rotating end of the leveling component 5 is located at the edge of the bottom formwork 1. When two adjacent bottom formwork 1s are spliced, the leveling component 5 can be rotated so that its free end faces the other bottom formwork 1 (the leveling component 5 on the other bottom formwork 1 performs the same action). By having the leveling components 5 on the two bottom formwork 1s contact the bottom formwork 1 on the adjacent side, it is ensured that the bottom formwork 1s on the same floor are all on the same horizontal plane, so that the height of the final floor is consistent throughout.

[0037] In this embodiment, the cross-sectional shape of the purlin 3 is Z-shaped, V-shaped, or inverted U-shaped. The purlin 3 is usually made of steel to provide stable support. The cross-sectional shape of the purlin 3 can be selected and designed according to the actual processing conditions. This invention does not limit the shape of the purlin 3.

[0038] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
