Description

Technical Field

[0001] This utility model relates to the field of prefabricated building components, specifically a prefabricated building component for assembly construction. Background Technology

[0002] Precast building components refer to building components that are manufactured in factories through mechanized production. They mainly include standardized parts such as wall panels, floor slabs, stairs, columns, and beams. Precast components are produced in factories according to precise design drawings, and standardized manufacturing is achieved through processes such as mold forming, rebar binding, and concrete pouring.

[0003] Precast floor slabs are required during the construction of houses. Traditional precast floor slabs have a simple structure. When transporting precast floor slabs, they usually need to be stacked. However, due to the lack of connecting structures between the precast floor slabs, the stacking is not stable enough. When the transport vehicle bumps and shakes, the stacked precast floor slabs are very easy to collapse, resulting in damage to the precast floor slabs. Utility Model Content

[0019] 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.

[0020] like Figures 1 to 4As shown, the present invention provides a prefabricated building component for assembly construction, including a prefabricated floor slab body 1. Cylindrical holes 2 are provided on both the front and rear sides of the prefabricated floor slab body 1. A screw rod 3 is fixedly connected to the inner wall of the cylindrical hole 2 at the rear center position. A threaded sleeve 4 is threaded onto the surface of the screw rod 3. A locking hole 6 is provided at the top of the prefabricated floor slab body 1 and at the top of the cylindrical hole 2. A locking block 7, which cooperates with the locking hole 6, is fixedly connected to the bottom of the prefabricated floor slab body 1 and at the bottom of the cylindrical hole 2. A through hole structure, which cooperates with the threaded sleeve 4, is provided on the outer side of the locking block 7.

[0021] refer to Figure 2 A knob 5 is fixedly connected to the outside of the screw sleeve 4, and the outside of the knob 5 passes through the cylindrical hole 2 to the surface of the precast floor slab body 1.

[0022] As a technical optimization of this utility model, by setting the knob 5, the contact area between the user's hands and the screw sleeve 4 can be increased, making it easier for the user to rotate the screw sleeve 4.

[0023] refer to Figure 1 and Figure 4 A protrusion 8 is fixedly connected to the left side of the precast floor slab body 1, and a groove 9 that cooperates with the protrusion 8 is provided on the right side of the precast floor slab body 1.

[0024] As a technical optimization of this utility model, by setting the protrusion 8 and the groove 9, the precast floor slab body 1 can be guided and limited when splicing left and right, which facilitates the use of users.

[0025] refer to Figure 2 Both screw 3 and screw sleeve 4 are made of stainless steel.

[0026] As a technical optimization of this utility model, by setting the screw 3 and the screw sleeve 4 made of stainless steel, it is possible to prevent the screw 3 and the screw sleeve 4 from rusting and to prevent the screw 3 and the screw sleeve 4 from being damaged due to rusting.

[0027] refer to Figure 2 The surface of knob 5 is provided with anti-slip texture 10.

[0028] As a technical optimization of this utility model, by setting anti-slip texture 10, the friction between the user's hands and the knob 5 can be increased, preventing the knob 5 from slipping out of the hand during use.

[0029] refer to Figure 2 The material of card block 7 is aluminum alloy.

[0030] As a technical optimization of this utility model, by setting the card block 7 made of aluminum alloy, the strength of the card block 7 can be increased, making the card block 7 less prone to breakage and damage.

[0031] The working principle and usage process of this utility model are as follows: In use, first align the locking block 7 on another precast floor slab body 1 with the locking hole 6, move the other precast floor slab body 1 and the locking block 7 downwards, so that the locking block 7 is inserted into the cylindrical hole 2 through the locking hole 6. Then align the threaded sleeve 4 with the cylindrical hole 2, move the threaded sleeve 4 inwards, so that the threaded sleeve 4 is inserted into the cylindrical hole 2. At the same time, the through hole structure on the locking block 7 passes through the locking block 7 and contacts the screw 3. Finally, turn the knob 5. The knob 5 drives the threaded sleeve 4 to rotate. The thread on the screw 3 causes the threaded sleeve 4 to move inwards until the screw 3 is completely rotated into the threaded sleeve 4. At this time, the precast floor slab body 1 can be stacked and fixed to achieve the effect of stacking and fixing. When assembling the precast floor slab body 1, the locking block 7 can be inserted into the filling hole reserved at the top of the wall for quick assembly and fixing.

[0032] In summary, this prefabricated building component, through the installation of a prefabricated floor slab body 1, cylindrical holes 2, screws 3, screw sleeves 4, knobs 5, locking holes 6, and locking blocks 7, solves the problem that traditional prefabricated floor slabs have simple structures and often require stacking during transportation. Furthermore, the lack of connecting structures between the prefabricated floor slabs leads to unstable stacking, making them prone to collapse and damage when transported by vehicles.
