Description

Technical Field

[0001] The present invention relates to the technical field of assembled partition walls, and in particular to an assembled partition wall connection device and a connection method. Background Art

[0002] Prefabricated partition boards have neat specifications and sizes, are easy to shape, facilitate mechanized production, have high production efficiency, can be installed in an assembled manner, and can achieve dry operations. Prefabricated partition boards have the advantages of light weight and thin boards. Compared with blocks and bricks, they can reduce the total load of the building, have a faster construction speed, and improve the construction efficiency of the construction project.

[0003] The connection method of prefabricated partitions directly determines the installation quality of the partitions. There are many existing related installation technologies. For example, patent application number 202110173752.8 discloses an assembled lightweight partition strip connection device using double dovetail connection, the connection device comprising a connecting groove correspondingly opened on the edge of the lightweight partition and a connecting piece for connecting the lightweight partitions together; the outer end of the connecting groove is open, and the inner diameter is smaller than the inner end, thereby forming a dovetail structure with two compression slopes; the connecting piece is matched and fitted in the connecting groove, and can compress the compression slope to bring the lightweight partitions closer to each other; the operation difficulty is greatly reduced, and the installation can be completed by basically 1-2 people, the construction difficulty coefficient is low, and the construction time and construction workload can be greatly reduced, etc., to provide construction efficiency, and secondary demolition can be easily achieved.

[0004] However, the expected effect of reducing the difficulty of operation was not achieved in the actual operation process. Specifically, the partition installation process needs to refer to the layout correction, including the correction of verticality and the flatness of the joint surface. The joints are staggered in size, and the partition walls need to be repeatedly disassembled and assembled for adjustment. The requirements cannot be met by covering the decorative surface layer. After a period of time, there will be problems such as bulging and falling off. The edges of the joints should not be chiseled, otherwise the area of ​​the subsequent filling will increase, and the quality of the filling will be difficult to guarantee. Wall cracks will appear in the later stage. Then, when the existing technology connects the partition walls, the original joint surface is severely damaged, which increases the difficulty of subsequent construction operations. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an assembled partition wall connection device and a connection method.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] Preferably, the surfaces of the first connecting plate and the second connecting plate are both provided with snap-in grooves, and snap-in plates are fixedly provided on the surfaces of the first connecting plate and the second connecting plate, and when the first connecting plate and the second connecting plate are brought close to each other, the snap-in plates can be inserted into the relative snap-in grooves.

[0011] Preferably, the first inclined block is rotatably connected to the first connecting plate, the second inclined block is rotatably connected to the second connecting plate, the first connecting plate and the second connecting plate have the same structure, and are both arranged in a long strip structure, the long side lengths of the first connecting plate and the second connecting plate are less than or equal to the long side lengths of the partition board, and the pre-tightening bolts are threadedly installed through the second inclined block and threadedly installed on the first inclined block

[0013] The present invention has the following beneficial effects:

[0014] (1) The assembled partition wall connection device proposed in the present invention does not need to be chiseled or damaged during the process of splicing the partition wall panels, and the original flat surface is maintained. The adjacent partition wall panels are tightened by the connection device to reduce the splicing gap. The subsequent filling area will be reduced to the greatest extent, or no filling is required. The decorative surface layer is not prone to cracking and bulging, the construction quality is easy to control, and the operation is simple, thereby improving the construction efficiency.

[0028] Example 1

[0029] Reference Figure 1-3 , an assembled partition wall connection device, comprising a first connection plate 1, a second connection plate 2, a first inclined block 3 and a second inclined block 4, the first inclined block 3 and the first connection plate 1 are movably connected, the second inclined block 4 and the second connection plate 2 are movably connected, and the surfaces of the first connection plate 1 and the second connection plate 2 are both provided with mounting holes, and the first connection plate 1 and the second connection plate 2 are respectively fixedly mounted on two partition wall plates butted against each other by inserting screws in the mounting holes;

[0030] The relative surfaces of the first inclined block 3 and the second inclined block 4 are inclined surfaces, and the first inclined block 3 and the second inclined block 4 are in sliding contact with each other through their inclined surfaces. The first inclined block 3 and the second inclined block 4 are pressed tightly by using pre-tightening bolts 5. The first inclined block 3 and the second inclined block 4 produce a displacement of mutual sliding through the inclined surfaces, and the first connecting plate 1 and the second connecting plate 2 are tightened toward the middle, so that the two partition boards are butted against each other, and the axis of the pre-tightening bolt 5 is perpendicular to the surface of the partition board.

[0031] In this embodiment, the first bevel block 3 is slidably connected to the first connecting plate 1, and the second bevel block 4 is slidably connected to the second connecting plate 2. The first connecting plate 1 and the second connecting plate 2 have the same structure, both of which adopt an L-shaped structure. Pre-tightening bolts 5 are respectively installed on the side threads of the first connecting plate 1 and the second connecting plate 2. The threaded end of the pre-tightening bolt 5 is pressed against the side of the first bevel block 3 or the second bevel block 4, so that the first bevel block 3 and the second bevel block 4 are pressed against each other.

[0032] The surfaces of the first connecting plate 1 and the second connecting plate 2 are both provided with a snap-in groove 7, and the surfaces of the first connecting plate 1 and the second connecting plate 2 are both fixedly provided with a snap-in plate 6. When the first connecting plate 1 and the second connecting plate 2 are close to each other and put together, the snap-in plate 6 can be inserted into the relative snap-in groove 7.

[0033] Example 2

[0034] Reference Figure 4, an assembled partition wall connection device, comprising a first connection plate 1, a second connection plate 2, a first inclined block 3 and a second inclined block 4, the first inclined block 3 and the first connection plate 1 are movably connected, the second inclined block 4 and the second connection plate 2 are movably connected, and the surfaces of the first connection plate 1 and the second connection plate 2 are both provided with mounting holes, and the first connection plate 1 and the second connection plate 2 are respectively fixedly mounted on two partition wall plates butted against each other by inserting screws in the mounting holes;

[0035] The relative surfaces of the first inclined block 3 and the second inclined block 4 are inclined surfaces, and the first inclined block 3 and the second inclined block 4 are in sliding contact with each other through their inclined surfaces. The first inclined block 3 and the second inclined block 4 are pressed tightly by using pre-tightening bolts 5. The first inclined block 3 and the second inclined block 4 produce a displacement of mutual sliding through the inclined surfaces, and the first connecting plate 1 and the second connecting plate 2 are tightened toward the middle, so that the two partition boards are butted against each other, and the axis of the pre-tightening bolt 5 is perpendicular to the surface of the partition board.

[0036] Different from Example 1, the first inclined block 3 and the first connecting plate 1 are rotatably connected, the second inclined block 4 is rotatably connected to the second connecting plate 2, the first connecting plate 1 and the second connecting plate 2 have the same structure, and are both arranged in a long strip structure. The long side length of the first connecting plate 1 and the second connecting plate 2 is less than or equal to the long side length of the partition board, and the pre-tightening bolt 5 is threadedly installed through the second inclined block 4 and threadedly installed on the first inclined block 3.

[0037] In this embodiment, a waist-shaped groove 8 is opened on the surface of the second inclined block 4, a clamping plate 9 is sleeved on the surface of the pre-tightening bolt 5, and then the pre-tightening bolt 5 passes through the waist-shaped groove 8 and is screwed into the second inclined block 4. Rollers 10 are rotatably installed on both sides of the clamping plate 9.

[0038] Reference Figure 5 , in order to meet different installation requirements, two partition board styles are proposed:

[0039] The first type of partition board has stepped sides. A cavity is formed inside the joint of the two partition boards. The joint connection components are installed in the cavity. This type of partition board is suitable for places with sufficient operating space on both sides, such as Figure 6 The middle partition wall shown in the figure, each unit partition wall board can be buckled and butted from the side, which is also convenient for workers to press on both surfaces of the partition wall board to correct the flatness. If the partition wall is used in a place with operating space on one side, it will not affect the installation operation, but it is more troublesome to correct the flatness;

[0040] The specific flatness correction method is as follows: the edge of a partition board is deformed, bent, and convex, and cannot be aligned with the adjacent partition board. The connecting device is installed here. In the process of tightening the pre-tightening bolt 5, inward pressure is applied to the convex part of the surface of the partition board to align the clamping plate 6 with the clamping groove 7. The pre-tightening bolt 5 is further tightened to insert the clamping plate 6 into the relative clamping groove 7. Figure 1 or 3.

[0041] The second type of partition board has two sides that are convex and concave respectively, and the concave and convex parts are butted together to form a cavity in the middle, and the butted connecting components are installed in the cavity. This type of partition board is relatively easy to use even in places where there is operating space on one side, such as the installation of internal insulation wall panels, where one side is adjacent to the wall and only the other side has the conditions for installation and operation;

[0042] Compared with the second partition board style, the first partition board style has the advantage that there will be no weak edges on both sides of the joint, and it is not easy to deform or bulge in the later stage; while the advantage of the second partition board style is that the concave and convex parts are butted together, and as long as the thickness of the two partition boards is the same, there is no need to adjust the flatness of both sides.

[0043] The method for splicing and assembling partition wall panels using the assembled partition wall connection device proposed in Example 1 or Example 2 includes the following specific steps:

[0044] S1. Construction layout: lay out the installation reference line 11 on the top beam of the building, and place the center reference line 12 on the side of the partition board. Figure 6 As shown;

[0045] S2, installation of the connection device, take the first partition board, fix the first connection board 1 on the side of the first partition board by screws, and ensure that the center line of the first connection board 1 is aligned with the center dividing reference line 12, take the second partition board, fix the second connection board 2 on the side of the second partition board by screws, and ensure that the center line of the second connection board 2 is aligned with the center dividing reference line 12;

[0046] S3, fix an L-shaped angle iron on the lower surface of the building top beam, insert a hanging bolt 13 on the L-shaped angle iron, and use the hanging bolt 13 to hang the first partition board on the lower side of the building top beam, ensuring that the axis of the hanging bolt 13 is parallel to the installation reference line 11, such as Figure 7 As shown;

[0047] S4. Correct the verticality of the first partition board, such as Figure 7 As shown, the partition board is swung left and right to correct the verticality, and a triangular pad is inserted at the end of the first partition board for temporary fixation, and then an L-shaped angle iron is installed between the side of the first partition board and the ground, and the first partition board is completely fixed;

[0048] S5, repeat step S3, install the second partition board, make the inclined surfaces of the first inclined block 3 and the second inclined block 4 overlap each other, and open operation holes 14 on the surfaces of the first partition board and the second partition board, tighten the pre-tightening bolts 5 at the operation holes 14 with a wrench, make the two partition boards butt against each other, and repeat step S4 to complete the complete fixation of the second partition board;

[0049] S6. Repeat the above steps to complete the assembly of subsequent partition panels.

[0050] For the above-mentioned installation method, the connecting device is designed inside the joint of adjacent partition boards. Only an operation hole 14 needs to be opened to tighten the pre-tightening bolt 5 from the outside. The operation hole 14 is located away from the joint and has a small area, with only one or more holes. There is no risk of cracking after the holes are filled, which facilitates construction.

[0051] It should be noted that if Figure 8 As shown, the connecting device applies a tensile force F2 to the two partition boards to make the joints fit tightly. The tensile force F2 is achieved by the pre-tightening bolts 5. The scheme proposed by the present invention makes the pressure or tensile force F1 borne by the pre-tightening bolts 5 be set in a vertical direction to the above-mentioned tensile force F2. The pre-tightening bolts 5 only bear the axial force F1 and are not easily cut off. The loss of the tensile force F1 due to fatigue or fracture of the pre-tightening bolts 5 can be effectively avoided, so that the installation of the partition wall is tight, more reliable and durable.

[0052] The connection device does not need to dig or damage the joint surface of the partition boards during the splicing process, and the original flat surface is maintained. The adjacent partition boards are tightened by the connection device to reduce the splicing gap. The subsequent filling area will be reduced to the greatest extent, or no filling is required. The decorative surface layer is not prone to cracking and bulging, the construction quality is easy to control, and the operation is simple, thereby improving the construction efficiency.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
