Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated wall panels, in particular to a splicable prefabricated wall panel for assembled buildings. Background Art

[0002] Precast wall panels, also known as wall panels or siding, are reinforced concrete slabs manufactured in a prefabrication plant or construction site for assembly into buildings. Using precast concrete wall panels to construct prefabricated, large-panel buildings can improve factory-based and mechanized construction, reduce on-site wet work, save on-site labor, mitigate seasonal influences, and shorten construction cycles.

[0003] Existing prefabricated wall panels are generally spliced ​​together using keyway connections and then installed with external fixings such as bolts or flanges. The installation is relatively cumbersome, so it is necessary to develop a new type of spliced ​​wall panel that can be installed using its own structure. Summary of the Invention

[0004] The object of the present invention is to provide a splicable prefabricated wall panel for assembled buildings to solve the problems raised in the above background technology.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: a prefabricated wall panel for assembled buildings that can be spliced, comprising a first wall panel and a second wall panel, wherein a connecting block is provided at the bottom of the first wall panel, a limiting groove is provided on one side of the connecting block, and a driving block is provided on one side of the connecting block;

[0006] The upper end surface of the second wall panel is provided with a receiving groove for receiving the connecting block. A slider is provided on one side of the receiving groove, and the slider has the freedom to slide toward one side of the receiving groove.

[0007] When the first wall panel is pressed downward, the connecting block enters the accommodating groove and is limited, the driving block pushes the sliding block into the limiting groove, and the sliding block limits the upward movement of the connecting block.

[0008] Preferably, both the left and right sides of the connecting block are provided with limiting grooves, and both the driving block and the sliding block are provided with two groups that are symmetrical to each other on the left and right sides.

[0009] Preferably, one side of the slider is provided with an inclined driving surface, and one side of the driving block is an oblique angle structure.

[0010] Preferably, the upper end surface of the connecting block is slightly higher than the depth of the accommodating groove, and a notch is provided on a side of the sliding block close to the accommodating groove for accommodating the portion of the connecting block higher than the accommodating groove.

[0011] Preferably, a junction box is provided at the bottom of the slider, and the junction box is connected to an elastic component. When the slider is located directly above the junction box, the junction box is squeezed into the second wall panel. When the slider slides into the limiting groove, the junction box is popped out by the elastic component.

[0012] Preferably, sliding pins are provided on both sides of the junction box, the sliding pins and the junction box are embedded in the second wall panel, and a spring is installed at the bottom of the sliding pin. When the slider slides out, the spring pops out the sliding pin.

[0013] Preferably, the slider is connected to a sliding shaft, which is slidably connected to the second wall panel. A guide block is sleeved on the sliding shaft, and the bottom of the guide block contacts the sliding pin. A side of the guide block away from the accommodating groove is provided with an inclined surface. When the sliding pin is released from contact with the inclined surface, it is gradually ejected by the spring.

[0014] The guide block is a U-shaped structure, and a limit ring is provided on the sliding shaft. A buffer spring is connected between the limit ring and the side wall of the guide block facing the accommodating groove. When the slider slides toward the side of the accommodating groove, the buffer spring is compressed first, and then the guide block is pushed to slide, and finally the sliding pin at the bottom is released.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention is designed based on the structure of the wall panel itself, and uses the position connection relationship between the connecting block, the accommodating groove and the slider to achieve self-locking. In addition, the downward pressure of the driving block is used to automatically complete the installation. There is no need for manual and detailed assembly process. The wall panels can be spliced ​​by simply stacking and combining them. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: See Figure 1 As shown in FIG, the first wall panel 1 and the second wall panel 2 are provided with a connecting block 12 at the bottom of the first wall panel 1, a limiting groove 121 is provided on one side of the connecting block 12, and a driving block 11 is provided on one side of the connecting block 12.

[0023] The upper end surface of the second wall panel 2 is provided with a receiving groove 22 for receiving the connecting block 12. A slider 21 is provided on one side of the receiving groove 22. The slider 21 has the freedom to slide toward the side of the receiving groove 22.

[0024] When the first wall panel 1 is pressed downward, the connecting block 12 enters the accommodating groove 22 and is limited. The driving block 11 pushes the sliding block 21 into the limiting groove 121, and the sliding block 21 limits the upward movement of the connecting block.

[0025] In another preferred embodiment, the connecting block 12 is provided with limit slots on both sides, and the driving block 11 and the slider 21 are provided with two mutually symmetrical groups. When pressed down, the sliders 21 on both sides enter the limit slots on both sides at the same time.

[0026] The structure of the driving block 11 and the slider 21 can be referred to Figure 1 as well as Figure 2 As shown, sliding is achieved by squeezing two inclined surfaces up and down.

[0027] In addition, during implementation, the upper end surface of the connecting block 12, namely the surface A in the figure, is slightly higher than the depth of the receiving groove 22, and a notch 212 is provided on the side of the slider 21 close to the receiving groove for accommodating the portion of the connecting block 12 that is higher than the receiving groove 22;

[0028] Because groove depth errors are prone to occur during processing, the height of the connecting block 12 is designed to be deeper than the accommodating groove 22, and a fault-tolerant notch 212 is made on the slider 21. This design also allows the slider 21 to maintain a relatively large contact area with the connecting block 12, so that if expansion occurs, the force is more evenly distributed, reducing the possibility of deformation.

[0029] Continuing with the figure, when the slider 21 slides out and reaches the limiting groove 121 for positioning, a clear gap will appear at the rear end of the slider 21. In this embodiment, this gap is used to install the junction box 28. Because the wall panel itself is prefabricated, it is possible to bury the wiring harness and connect the junction box 28. Specifically, the bottom of the slider 21 is provided with a junction box 28, and the junction box 28 is connected to an elastic component. When the slider 21 is located directly above the junction box 28, the junction box 28 is squeezed into the second wall panel 2. When the slider 21 slides into the limiting groove 121, the elastic component acts to eject the junction box 28. After the junction box 28 is ejected, the terminal posts on its side can be exposed in the gap formed in the wall panel due to the sliding of the slider 21. During the wiring installation, a wall socket or other electrical components can be installed in this gap.

[0030] Reference Figure 2 and Figure 3As shown, sliding pins 26 are provided on both sides of the junction box 28. The sliding pins 26 and the junction box 28 are embedded in the second wall panel 2. A spring 27 is installed at the bottom of the sliding pins 26. When the slider 21 slides out, the spring 27 ejects the sliding pins 26. The slider 21 is connected to a sliding shaft 25, which is slidably connected to the second wall panel 2. A guide block 23 is sleeved on the sliding shaft 25. The bottom of the guide block 23 contacts the sliding pin 26. The side of the guide block 23 away from the receiving groove 22 is provided with an inclined surface. When the sliding pin 26 contacts the inclined surface, it is gradually ejected by the spring 27.

[0031] The guide block 23 is a U-shaped structure, and a limit ring is provided on the sliding shaft 25. A buffer spring 24 is connected between the limit ring and the side wall of the guide block facing the accommodating groove 22. When the slider 21 slides toward the side of the accommodating groove 22, the buffer spring 24 is first compressed, and then the guide block 23 is pushed to slide, and finally the sliding pin 26 at the bottom is released.

[0032] Reference Figure 3 As shown, the solution of ejecting the junction box 28 by means of the spring 27 is relatively simple, requires fewer components to be installed, and is more stable. The use of the guide block 23 and the buffer spring 24 is to allow the slider 21 to slide a certain distance before starting to feedback to the slide pin 26 when the slider 21 slides. If the guide block 23 and the buffer spring 24 are not provided, given that the junction box 28 and the slider 21 both have a certain length, in order to prevent interference between the movements of the two, the junction box 28 can only be ejected after the slider 21 slides out completely. In this case, a relatively long limiting distance is required, and the friction is relatively large, causing unnecessary resistance when sliding, and may also cause jamming. The provision of the guide block 23 and the buffer spring 24 solves this problem. When working, refer to Figure 3 The slider 21 first slides to the left. At this time, the guide block is stationary, and the limit ring on the slide shaft 25 compresses the buffer spring 24 to the left. After sliding a certain distance, the buffer spring 24 is compressed to a certain extent and quickly resets to push the guide block 23 to slide to the left. With the help of the buffer spring 24, the junction box 28 is quickly ejected to prevent it from getting stuck.
