Description

Technical Field

[0001] This utility model relates to the field of prefabricated composite slab technology, and in particular to a prefabricated composite slab that does not require demolding. Background Technology

[0002] Composite floor slabs are assembled monolithic floor slabs made by stacking precast slabs and cast-in-place reinforced concrete layers. Composite floor slabs have good integrity, and the upper and lower surfaces of the slab are flat, which facilitates the finishing layer decoration. They are suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity.

[0003] Traditional composite slab construction requires on-site formwork erection, which must be removed after concrete pouring, resulting in cumbersome procedures, time-consuming and material-intensive processes. While existing prefabricated composite slabs can be partially prefabricated, the connection nodes are complex, and the overall integrity and waterproof performance are insufficient. Furthermore, traditional composite slabs are heavy and lack functional designs for sound insulation and thermal insulation. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical machining center for grinding irregularly shaped workpieces in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A prefabricated composite slab that does not require demolding includes a precast base slab and a protective layer. The precast base slab has embedded truss reinforcement bars and is covered with a permanent formwork layer with a waterproof coating. The protective layer is also provided with corrugated distribution bars and reinforcing components on its surface.

[0007] As a further description of the above technical solution:

[0008] The reinforcing component includes reinforcing ribs, which are welded and fixed to the truss steel bars. The reinforcing component also includes top ribs disposed above the reinforcing ribs. The top ribs and reinforcing ribs are vertically staggered, and a connecting frame is provided between the top ribs and the reinforcing ribs.

[0009] As a further description of the above technical solution:

[0010] The connecting frame has an oblique triangular structure, and two sets of oblique braces of the connecting frame are welded and fixed to the reinforcing ribs, while the other set of oblique braces of the connecting frame is welded and fixed to the corrugated distribution ribs.

[0011] As a further description of the above technical solution:

[0012] The surface of the reinforcing rib is also provided with a protective rib, which is located between the connecting frames and penetrates the protective layer to be fixed to the truss reinforcement.

[0013] As a further description of the above technical solution:

[0014] The waveform distribution ribs are arranged in a sine curve with a peak spacing of 200mm.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] In this utility model, the precast base plate and permanent template layer are directly used as the decorative base layer, reducing the demolding process and shortening the construction period. The protective layer enables sound insulation, heat preservation and waterproofing to be integrated, improving the heat preservation effect. Furthermore, the three-dimensional welding of the corrugated distribution bars and the truss bars enhances the overall seismic performance. Attached Figure Description

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-2 This utility model provides a technical solution: a prefabricated composite slab that does not require demolding, comprising a prefabricated base plate 1 and a protective layer 2. The prefabricated base plate 1 has pre-embedded truss steel bars, and the surface of the prefabricated base plate 1 is also covered with a permanent template layer with a waterproof coating. The protective layer 2 is also embedded with corrugated distribution bars, which are arranged in a sinusoidal curve with a peak spacing of 200mm. The three-dimensional welding of the corrugated distribution bars and the truss steel bars improves the overall seismic performance, and the surface of the protective layer 2 is also provided with reinforcing components.

[0022] The reinforcing component includes a reinforcing rib 3, which is welded and fixed to the truss steel bars. The reinforcing component also includes a top rib 4 disposed above the reinforcing rib 3. The top rib 4 and the reinforcing rib 3 are vertically staggered, and a connecting frame 5 is provided between the top rib 4 and the reinforcing rib 3.

[0023] The connecting frame 5 has an oblique triangular structure, and two sets of oblique braces of the connecting frame 5 are welded and fixed to the reinforcing rib 3. The other set of oblique braces of the connecting frame 5 is welded and fixed to the corrugated distribution rib. Through the triangular structure of the connecting frame 5, not only can the top rib 4 and the reinforcing rib 3 form a whole, increasing the overall strength, but also the cavity above the protective layer 2 can be easily filled, improving the heat insulation and sound insulation effect of the composite board in the later use.

[0024] The surface of the reinforcing rib 3 is also provided with a protective rib 6. The protective rib 6 is located between the connecting frames 5 and passes through the protective layer 2 and is fixed to the truss steel bars. The protective rib 6 can play an auxiliary strengthening role, so that the reinforcing rib 3, the protective plate 2 and the precast base plate 1 form an integral whole, and improve the overall strength of the composite plate.
