Description

Technical Field

[0001] The utility model relates to the technical field of wall panels, in particular to a vertical splicing type lightweight precast concrete wall panel. Background Technique

[0002] Wall panels are important building materials widely used in various buildings. They play key roles in many aspects in construction. Firstly, they can effectively separate spaces, divide the interior of buildings into different functional areas, and meet the diverse living, working and production needs of people. Secondly, as an important part of the building structure system, wall panels cooperate with columns, beams, etc. to provide necessary structural support for buildings, ensuring their stability and safety.

[0003] At present, most of the splicing wall panels on the market often have the problem of unstable connection, which makes the connection strength between adjacent wall panels relatively low, and it is easy to loosen and misalign due to external forces during use, affecting the stability and aesthetics of the building. In addition, during construction, their installation and disassembly are relatively troublesome, consuming a lot of time and energy of construction workers and prolonging the construction period and cost.

[0004] In view of this, in response to the problems of unstable connection and difficult installation and disassembly, this application proposes a vertical splicing type lightweight precast concrete wall panel. Content of the Utility Model

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a vertical splicing type lightweight precast concrete wall panel is proposed. By rotating a bidirectional lead screw, a clamping plate is pushed into a clamping groove to quickly fix two wall panel bodies, and by squeezing a pressure-receiving plate with a squeezing plate, a sealing plate is pushed into a sealing groove, thereby strengthening the sealing performance at the joint of the two wall panel bodies.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a vertical splicing type lightweight precast concrete wall panel, including a wall panel body. A convex block is fixedly connected to the left end of the wall panel body, and a groove is opened at the right end of the wall panel body. The convex block and the groove are in a matching shape. A bidirectional lead screw is rotatably connected to the inner wall of the convex block. The bidirectional lead screw is connected to clamping plates on the front and rear sides through a moving component for moving the clamping plates out of the convex block. The outer walls of the clamping plates on the front and rear sides are slidably connected to the inner wall of the convex block. Clamping grooves are opened on the inner walls of the front and rear sides of the groove. The clamping grooves and the clamping plates are in a matching shape. A squeezing plate is slidably connected to the inner walls of the front and rear sides of the clamping grooves. The squeezing plate is connected to a sealing plate through a squeezing component for strengthening the sealing performance of the connection between two wall panel bodies.

[0007] Furthermore, positioning blocks are fixedly connected to the upper and lower sides of the front and rear ends of the convex block, and positioning grooves are opened on the upper and lower sides of the front and rear ends of the inner wall of the groove. The positioning blocks and the positioning grooves are in a matching shape.

[0008] Furthermore, the moving component includes sliders threadedly connected to the upper and lower sides of the outer wall of the bidirectional lead screw. The front and rear ends of each slider are rotatably connected to a first connecting rod, and the other ends of the connecting rods on the left and right sides are respectively rotatably connected to the opposite ends of the clamping plate.

[0009] Furthermore, the extrusion component includes pressure-receiving plates closely attached to the opposite ends of the extrusion plate. The right ends of the pressure-receiving plates are fixedly connected to sealing plates, and the outer walls of the sealing plates are respectively slidably connected to the inner walls of the wall panel body.

[0010] Furthermore, a plurality of tension springs are fixedly connected to the upper and lower sides of the left end of the pressure-receiving plate, and the other ends of the tension springs are fixedly connected to the left end inner wall of the wall panel body.

[0011] Furthermore, sealing grooves are formed in the front and rear sides of the left end of the wall panel body, and the sealing plates are in conformity with the shapes of the sealing grooves.

[0012] Furthermore, a slotted cross recess is formed at the top end of the bidirectional lead screw for driving the rotation of the bidirectional lead screw.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the rotation of the bidirectional lead screw is driven by the slotted cross recess, so that the sliders on the upper and lower sides approach each other, and the clamping plate is pushed into the clamping groove, thereby conveniently fixing the two wall panel bodies together without complex tools and cumbersome operation processes, greatly improving the installation efficiency and saving the installation time and labor costs.

[0015] 2. In the utility model, the extrusion plate is pushed by the clamping plate, so that the extrusion plate extrudes the pressure-receiving plate to push the sealing plate into the sealing groove of the next wall panel body, thereby enhancing the sealing performance at the joint of the two wall panel bodies, strengthening the integrity of the wall panel, and not easily causing problems such as loosening and deformation due to poor sealing at the joint.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: a vertical spliced lightweight precast concrete wall panel, including a wall panel body 1, a protruding block 2 is fixedly connected to the left end of the wall panel body 1, a groove 3 is opened at the right end of the wall panel body 1, the protruding block 2 and the groove 3 are in a matching shape, a bidirectional lead screw 6 is rotatably connected to the inner wall of the protruding block 2, a one-word groove 10 is opened at the top of the bidirectional lead screw 6 for driving the rotation of the bidirectional lead screw 6, slide blocks 7 are threadedly connected to the upper and lower sides of the outer wall of the bidirectional lead screw 6, first connecting rods 8 are rotatably connected to the front and rear ends of the slide blocks 7, and the other ends of the left and right connecting rods 8 are respectively rotatably connected to the opposite ends of the clamping plate 9 for moving the clamping plate 9 out of the inside of the protruding block 2, the outer walls of the front and rear clamping plates 9 are slidably connected to the inner wall of the protruding block 2, clamping grooves are opened on the front and rear inner walls of the groove 3, the clamping grooves and the clamping plate 9 are in a matching shape, positioning blocks 4 are fixedly connected to the upper and lower sides of the front and rear ends of the protruding block 2, positioning grooves 5 are opened on the upper and lower sides of the front and rear ends of the inner wall of the groove 3, and the positioning blocks 4 and the positioning grooves 5 are in a matching shape.

[0025] Specifically, first insert the convex block 2 of the second wall panel body 1 into the groove 3 of the first wall panel body 1, and align and insert the positioning block 4 on the convex block 2 into the positioning groove 5. This makes it difficult for the subsequent clamping plate 9 to fail to enter the card slot due to misalignment when it enters the card slot. Then use a flat-blade screwdriver to rotate the flat slot 10 at the top of the bidirectional screw rod 6 on the second wall panel body 1. The rotation of the bidirectional screw rod 6 causes the sliders 7 on the upper and lower sides to approach each other, so that the connecting rods 8 on both sides support outward, and then the clamping plate 9 extends out of the convex block 2 and enters the card slot on the first wall panel body 1, so that the two wall panel bodies 1 are clamped together. When disassembling, just rotate the bidirectional screw rod 6 in the reverse direction to retract the clamping plate 9 into the convex block 2, and then the two wall panel bodies 1 can be separated.

[0026] Refer to Figure 4 and Figure 5 As shown in Figure 4 and Figure 5 , there are extrusion plates 11 slidingly connected to the inner walls of the front and rear card slots. Pressure-receiving plates 12 are closely attached to the opposite ends of the extrusion plates 11. Sealing plates 13 are fixedly connected to the right ends of the pressure-receiving plates 12. The outer walls of the sealing plates 13 are respectively slidingly connected to the inner walls of the wall panel body 1. A plurality of tension springs 15 are fixedly connected to the upper and lower sides of the left end of the pressure-receiving plate 12, and the other ends of the tension springs 15 are fixedly connected to the left end inner wall of the wall panel body 1. Sealing grooves 14 are provided on the front and rear sides of the left end of the wall panel body 1, and the sealing plates 13 are in conformity with the shapes of the sealing grooves 14 to be used for strengthening the sealing performance of the connection between the two wall panel bodies 1.

[0027] Specifically, when the clamping plate 9 enters the card slot, it will push the extrusion plate 11. The extrusion plate 11 will squeeze the pressure-receiving plate 12. The pressure-receiving plate 12 will stretch the tension spring 15, and at the same time cause the pressure-receiving plate 12 to drive the sealing plate 13 to move outward, and then enter the sealing groove 14, thereby strengthening the sealing performance of the connection between the two wall panel bodies 1 and enhancing the integrity of the wall panel. When the clamping plate 9 disengages from the card slot, the tension spring 15 will pull back the pressure-receiving plate 12. The pressure-receiving plate 12 will pull the sealing plate 13 back into the wall panel body 1, and at the same time the pressure-receiving plate 12 will push the extrusion plate 11 back to its original position.

[0028] Working principle: During installation, insert the convex block 2 of the lower wall panel body 1 into the groove 3 of the upper wall panel body 1, and align and insert the positioning block 4 on the convex block 2 into the positioning groove 5. This makes it difficult for the wall panel body 1 to be misaligned during connection. Then use a flat-blade screwdriver to rotate the flat slot 10 at the top of the bidirectional screw rod 6. The rotation of the bidirectional screw rod 6 causes the sliders 7 on the upper and lower sides to approach each other, so that the connecting rods 8 on both sides support outward, and then the clamping plate 9 extends out of the convex block 2 and enters the card slot, so that the two wall panel bodies 1 are clamped together. When the clamping plate 9 enters the card slot, it will push the extrusion plate 11. The extrusion plate 11 will squeeze the pressure-receiving plate 12, so that the pressure-receiving plate 12 drives the sealing plate 13 to move outward, and then enter the sealing groove 14, thereby strengthening the sealing performance of the connection between the two wall panel bodies 1 and enhancing the integrity of the wall panel, and it is not easy to have problems such as loosening and deformation caused by poor sealing at the connection.

[0029] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
