[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated composite floor slab, comprising a top slab and a bottom slab located below the top slab. Two assembly slots are symmetrically opened on both sides of the bottom slab. An insertion hole is opened on one side of each assembly slot. A fixing bolt is movably inserted into the inner side of the insertion hole. A nut is screwed to the tail of the fixing bolt. A damping plate is connected to the top of the top slab, and a sound insulation plate is connected between the damping plate and the top slab. Multiple positioning columns are connected side by side on one side of the damping plate, and multiple positioning holes corresponding to the positioning columns are opened side by side on the other side of the damping plate.

[0007] Preferably, the damping plate has multiple screw holes arranged side by side on one side, and the corresponding end of the positioning post is threaded into the corresponding screw hole.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a prefabricated composite floor slab, including a top plate 1 and a bottom plate 4 located below the top plate 1. Two assembly slots 5 are symmetrically formed on both sides of the bottom plate 4. An insertion hole is provided on one side of each assembly slot 5, and a fixing bolt 6 is movably inserted into the inner side of the insertion hole. The tail of the fixing bolt 6 passes through the insertion hole of an adjacent composite floor slab, and a nut 7 abuts against the corresponding side of the assembly slot 5 of the adjacent composite floor slab. Two sets of this structure can connect and fix two adjacent composite floor slabs. The tail of the fixing bolt 6 is screwed with a nut 7. The top of the top plate 1 is connected to a damping plate 3, which can achieve vibration reduction using existing principles. A sound insulation plate 2 is connected between the damping plate 3 and the top plate 1, which can achieve sound insulation using existing principles. Multiple positioning columns 13 are connected side by side on one side of the damping plate 3, and multiple positioning holes (not shown in the figure) corresponding to the positioning columns 13 are opened side by side on the other side of the damping plate 3. When adjacent composite floor slabs are assembled, the positioning columns 13 will be inserted into the adjacent positioning holes to complete the positioning, so as to facilitate the subsequent connection and fixation of the fixing bolts 6 and nuts 7.

[0023] Specifically, multiple screw holes 12 are arranged side by side on one side of the damping plate 3, and the corresponding end of the positioning post 13 is threaded into the corresponding screw hole 12, which makes it convenient to install the positioning post 13 on the corresponding side of the damping plate 3, and can also be easily removed when not needed.

[0024] Furthermore, a blocking plate 9 is hinged to one side of the assembly slot 5. The blocking plate 9 can block the assembly slot 5 to prevent dust and water from entering. The side of the blocking plate 9 away from the assembly slot 5 is integrally molded with an insert 10. The integrally molded structure is more durable and has higher structural strength.

[0025] Furthermore, the side of the assembly groove 5 away from the blocking plate 9 is provided with a slot 11, and the slot 11 has the same length, width and height as the plug-in 10. The plug-in 10 can be inserted into the slot 11 to stably fix the blocking plate 9.

[0026] It is worth noting that multiple reinforcing ribs 14 are cast side by side on the inner side of the damping plate 3. These multiple reinforcing ribs 14 can increase the structural strength of the damping plate 3 and improve its service life.

[0027] It is worth noting that the corresponding sides of the top plate 1, sound insulation plate 2, shock absorption plate 3 and bottom plate 4 are flush, which increases the integrity of the device and makes it easier to assemble.

[0028] It is worth mentioning that the side wall of the fixing bolt 6 is fitted with a washer 8, and the washer 8 is supported between the head of the fixing bolt 6 and the corresponding side of the mounting groove 5. The washer 8 can prevent the fixing bolt 6 from being tightened too much, making it easy to remove the fixing bolt 6.

[0029] Among them, the sound insulation panel 2 is existing technology and will not be described in detail; at the same time, this utility model also includes a power supply, controller, and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle: After the current composite floor slab is assembled and fixed, align the positioning hole of the next composite floor slab with the positioning post 13 of the current composite floor slab and tighten it. At this time, the positioning post 13 will be inserted into the positioning hole to complete the positioning. Then, insert the fixing bolt 6 into the insertion hole of the corresponding assembly slot 5 and tighten the nut 7. Finally, flip the blocking plate 8 and insert the plug 10 into the corresponding slot 11 to complete the connection and fixation of two adjacent composite floor slabs. Repeat the above steps to complete the assembly of multiple sets of composite floor slabs. It is more convenient to assemble multiple sets of composite floor slabs.
