Description

Technical Field

[0001] This application relates to the field of splicing component technology, and in particular to a splicing installation component and a prefabricated wall panel installation structure. Background Technology

[0002] Wall panel installation structures mostly use devices such as clips and splicing strips for fixing. Clips are usually installed along the top and bottom edges of the wall to fix the edges of the wall panels; splicing strips, through the cooperation of fixing strips and cover strips, provide a stable connection between two wall panels.

[0003] Among them, the splicing strip has a relatively simple structure, connecting to the wall with expansion bolts to fix and support the wall panel. However, most splicing strips adopt a traditional interlocking structure, relying on the principle of barbs to firmly connect the fixing strip and the cover strip. Although this structure can provide high stability, its disassembly process often requires forcibly breaking the connection part, causing irreversible damage, and it is difficult to achieve non-destructive disassembly and reuse, thus increasing the fixing cost of the wall panel.

[0004] Therefore, existing splicing strips have the problem that once fixed, they cannot be disassembled and reused. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a splicing installation component and a prefabricated wall panel installation structure, which aims to solve the problem that existing splicing strips cannot be disassembled and reused after being fixed.

[0006] The technical solution adopted by this application to solve the technical problem is as follows: On the one hand, this application provides a splicing and installation component, including:

[0007] The splicing strip includes a fixing strip and a cover strip, and the cover strip is provided with a plurality of insert strips; when the insert strips are engaged with the fixing strip, the cover strip and the fixing strip are locked; a gap is provided between adjacent insert strips;

[0008] A torsion device is disposed within the gap; the torsion device includes a rotating rod and a pull rope, one end of the pull rope is connected to the insert, and the other end is connected to the rotating rod; when the rotating rod is rotated, the pull rope can be pulled to cause the insert to bend along the direction close to the rotating rod, thereby realizing the unlocked state of the insert and the fixing strip.

[0009] Optionally, the fixing strip is provided with a first side strip and a second side strip, and a recessed engaging slot is formed between the first side strip and the second side strip; when the engaging slot engages with the insert strip, the cover strip and the fixing strip are locked together.

[0010] Optionally, the insert includes a first insert and a second insert; the first insert is provided with a first hook portion, and the first side strip is provided with a first side hook portion corresponding to the first hook portion;

[0011] The second insert is provided with a second hook portion, and the second side strip is provided with a second side hook portion corresponding to the second hook portion.

[0012] Optionally, the torsion device further includes a raised strip disposed within the gap; the raised strip has an insertion hole, and the rotating rod is located within the insertion hole.

[0013] Optionally, the raised strip is provided with a through hole corresponding to the pull rope.

[0014] Optionally, the raised strip is provided with a deflector strip, and the pull rope is connected to the insert strip after being guided by the deflector strip.

[0015] Optionally, the insert is provided with a binding hole corresponding to the pull rope.

[0016] On the other hand, this application also provides a prefabricated wall panel installation structure, which includes the splicing installation components described above.

[0017] Optionally, the prefabricated wall panel installation structure further includes a retaining strip, which is disposed above the splicing installation component or below the splicing installation component; the retaining strip is connected to the fixing strip.

[0018] Optionally, a placement cavity is formed between the card strip and the splicing installation component, the placement cavity being used to place the wall panel.

[0019] Compared with the prior art, this application provides a splicing installation component and a prefabricated wall panel installation structure. The splicing installation component includes a splicing strip and a torsion device. The splicing strip is fixed to the fixing strip by a plug on the cover strip, achieving a locked state. The torsion device is set in the gap. By rotating the rotating rod, the pull rope is pulled, thereby causing the plug connected to the pull rope to bend in the direction close to the rotating rod, that is, bending the plug in the direction away from the fixing strip, reducing the tightness of the connection between the plug and the fixing strip, until the plug and the fixing strip are separated, achieving an unlocked state. In this state, the splicing installation component can be quickly and non-destructively disassembled. When the pulling force on the pull rope is removed, the plug returns to its original shape and re-engages with the fixing strip. That is, the splicing installation component of this application can be disassembled and reused, which is simple and quick to operate and reduces costs. Attached Figure Description

[0030] Reference Figure 1 and Figure 2 The first embodiment of this application provides a splicing installation component, including a splicing strip 2 and a torsion device 1. The splicing strip 2 includes a fixing strip 21 and a cover strip 22. The cover strip 22 is provided with a plurality of inserts. When the inserts are engaged with the fixing strip 21, the cover strip 22 and the fixing strip 21 are locked. A gap is provided between adjacent inserts. The torsion device 1 is disposed in the gap. The torsion device 1 includes a rotating rod 11 and a pull rope 12. One end of the pull rope 12 is connected to the insert and the other end is connected to the rotating rod 11. When the rotating rod 11 is rotated, the pull rope 12 is pulled, thereby causing the insert connected to the pull rope 12 to bend along the direction close to the rotating rod 11, thereby unlocking the insert from the fixing strip 21.

[0031] The cover strip 22 is engaged with the fixing strip 21 by inserting a strip, thereby locking the cover strip 22 and the fixing strip 21; the cover strip 22 and the fixing strip 21 are detachably connected by a torsion device 1.

[0032] The torsion device 1 is installed within the gap, which provides space for the insertion strip to deform and bend. One end of the pull rope 12 is connected to the insertion strip. Pulling the pull rope 12 causes the insertion strip to bend along the direction of the rotating rod 11 located within the gap, that is, bending away from the connection point with the fixing strip 21. The frequency of rotating the rotating rod can be adjusted to adjust the tension on the pull rope, thereby adjusting the degree of bending of the insertion strip and the tightness of the connection between the insertion strip and the fixing strip 21, until the insertion strip separates from the fixing strip 21, achieving the unlocked state of the insertion strip and the fixing strip 21. At this time, the insertion strip can be pulled out from the fixing strip 21, which can achieve non-destructive disassembly of the splicing strip 2 and the splicing installation components, or reduce the damage to the splicing strip 2 during disassembly, facilitating the subsequent reuse of the splicing strip 2. Specifically, the other end of the pull rope 12 is partially tied to the rotating rod 11.

[0033] In addition, the pull rope 12 can be looped around the rotating rod 11 at least once, with one end exposed and the other end connected to the insert. When the pull rope 12 is pulled, the rotating rod 11 rotates, thereby using the rotational force of the rotating rod 11 to pull the pull rope 12, causing the pull rope 12 to drive the insert to bend along the direction close to the rotating rod 11.

[0034] The insert is made of elastic material and has elasticity; when the rotating rod 11 stops rotating, the pull rope 12 connected to the rotating rod 11 releases the rotational force, and the insert springs back to its original position according to its elastic restoring force.

[0035] Insert the unlocked insert into the fixing bar 21, then stop rotating the lever 11 so that the pull rope 12 is not subjected to external force. The insert will then re-engage with the fixing bar 21, achieving the locked state.

[0036] The splicing and installation assembly of this embodiment includes a splicing strip 2 and a torsion device 1. The splicing strip 2 is fixed to the fixing strip 21 by the insert on the cover strip 22, achieving a locked state. The torsion device 1 is set in the gap. By rotating the rotating rod 11, the pull rope 12 is pulled, thereby causing the insert connected to the pull rope 12 to bend along the direction close to the rotating rod 11, reducing the tightness of the connection between the insert and the fixing strip 21, until the insert is separated from the fixing strip 21, achieving an unlocked state. In this state, the splicing and installation assembly can be quickly and non-destructively disassembled. When the pulling force on the pull rope 12 disappears, the insert returns to its original shape and re-engages with the fixing strip 21. That is, the splicing and installation assembly of this embodiment can be disassembled and reused, which is simple and quick to operate and reduces costs.

[0037] In some embodiments, the fixing strip 21 is provided with a first side strip 211 and a second side strip 212, and a recessed engaging slot is formed between the first side strip 211 and the second side strip 212; when the engaging slot engages with the insert strip, the cover strip 22 and the fixing strip 21 are locked together.

[0038] The engaging slot corresponds to the insert strip, and the size of the engaging slot can be adjusted by setting the spacing between the first side strip 211 and the second side strip 212, thereby adjusting the engagement tightness between the engaging slot and the insert strip. The spacing between the first side strip 211 and the second side strip 212 is preferably larger than the gap between adjacent insert strips to facilitate the insertion of the insert strip with the torsion device 1.

[0039] Furthermore, the insert includes a first insert 221 and a second insert 222; the first insert 221 is provided with a first hook portion 2211, and the first side strip 211 is provided with a first side hook portion 2111 corresponding to the first hook portion 2211; the second insert 222 is provided with a second hook portion 2221, and the second side strip 212 is provided with a second side hook portion 2121 corresponding to the second hook portion 2221.

[0040] The first insert strip 221 and the first side strip 211 are fixedly connected by the first insert hook 2211 and the first side hook 2111. Based on the barb principle, this can enhance the connection tightness between the fixing strip 21 and the cover strip 22. Similarly, the second insert strip 222 and the second side strip 212 are fixedly connected by the second insert hook 2221 and the second side hook 2121. Based on the barb principle, this can enhance the connection tightness between the fixing strip 21 and the cover strip 22.

[0041] One end of the pull rope 12 is connected only to the first insert 221, thereby causing the first insert 221 to bend in the direction close to the rotating rod 11, first releasing the locking state of the first hook part 2211 and the first side hook part 2111, and then releasing the locking state of the second hook part 2221 and the second side hook part 2121, so that the cover strip 22 is separated from the fixing strip 21; or, one end of the pull rope 12 is connected only to the second insert 222, thereby causing the second insert 222 to bend in the direction close to the rotating rod 11, first releasing the locking state of the second hook part 2221 and the second side hook part 2121, and then releasing the locking state of the first hook part 2211 and the first side hook part 2111, so that the cover strip 22 is separated from the fixing strip 21.

[0042] Preferably, one end of the pull cord 12 is connected to both the first insert 221 and the second insert 222. When the pull cord 12 is pulled, the first insert 221 and the second insert 222 simultaneously bend along the direction closer to the rotating rod 11, thereby achieving the unlocked state and improving unlocking efficiency. Specifically, the first hook portion 2211 and the second hook portion 2221 are connected to the pull cord 12, facilitating the direct bending of the first hook portion 2211 and the second hook portion 2221 by the tension of the pull cord 12, thus improving unlocking efficiency.

[0043] The cover strip 22 may be provided with a number of inserts, namely a number of first inserts 221 and second inserts 222. The fixing strip 21 is provided with a number of first side strips 211 corresponding to the first inserts 221 and second side strips 212 corresponding to the second inserts 222. By adding the first inserts 221 and second inserts 222, and the first side strips 211 and second side strips 212, the connection tightness between the cover strip 22 and the fixing strip 21 is strengthened.

[0044] The torsion device 1 may be equipped with several pull ropes 12. Specifically, the number of pull ropes 12 corresponds to the number of inserts, that is, the pull ropes 12 are used to connect the first insert 221 and the second insert 222, pulling the corresponding first insert 221 and the second insert 222 to bend along the direction close to the rotating rod 11. One end of each of the pull ropes 12 is partially connected to the rotating rod 11, and the other end is connected to the inserts. Rotating the rotating rod 11 can convert the rotational force into a pulling force through the pull ropes 12, which acts on the inserts (including the first insert 221 and the second insert 222). Thus, by adding pull ropes 12 and their corresponding inserts, the force acting on the inserts is increased, thereby improving the unlocking efficiency.

[0045] The torsion device 1 can have one or more rotating rods 11. Specifically, when there is only one rotating rod 11, rotating the rotating rod 11 can pull all the pull ropes 12 on the rotating rod 11; when there are multiple rotating rods 11, rotating one of the rotating rods 11 can pull the corresponding pull rope 12, thereby driving all the other rotating rods 11 to rotate and pulling all the pull ropes 12. That is, when there are multiple rotating rods 11, the number of rotating rods 11 corresponds one-to-one with the number of pull ropes 12. The number of rotating rods 11 and pull ropes 12 can be set according to the length of the cover strip 22 and the tightness of the engagement between the insert strip and the fixing strip 21, so that while meeting the tightness of the engagement between the cover strip 22 and the fixing strip 21, the user can use a smaller pulling force to pull the pull rope 12 to achieve the unlocking state between the insert strip and the fixing strip 21.

[0046] Furthermore, the insert is provided with a binding hole corresponding to the pull rope 12. The pull rope 12 can be fixedly connected to the insert through the binding hole, which improves the connection stability between the pull rope 12 and the insert. The binding hole is preferably located at the hook part of the insert, so that the force on the pull rope 12 can be directly applied to the hook part of the insert, causing the hook part to bend.

[0047] Specifically, both the first hook portion 2211 and the second hook portion 2221 can be provided with binding holes. The pull rope 12 can be connected to the first hook portion 2211 and the second hook portion 2221 through the binding holes, or it can be bound to the first hook portion 2211 and the second hook portion 2221 through the binding holes, so that the force acting on the pull rope 12 is directly applied to the first hook portion 2211 and the second hook portion 2221, which makes it easier to bend the first hook portion 2211 and the second hook portion 2221 along the direction close to the rotating rod 11 at the same time, thereby improving the unlocking efficiency.

[0048] In some embodiments, the torsion device 1 further includes a raised strip 13 disposed within the gap; the raised strip 13 has an insertion hole 131, and the rotating rod 11 is located within the insertion hole 131. The raised strip 13 is fixedly connected to the gap between itself and the insertion strip, or the raised strip 13 is fixedly disposed within the gap, thereby fixing the torsion device 1 to the cover strip 22. Specifically, the torsion device 1 and the cover strip 22 can be manufactured and processed separately, and then fixedly connected to the cover strip 22 via the raised strip 13; or, the raised strip 13 and the cover strip 22 can be integrally formed.

[0049] The rotating rod 11 is located within the insertion hole 131 of the raised strip 13. A gap exists between the rotating rod 11 and the insertion hole 131 to facilitate connection between the rotating rod 11 and the pull rope 12, and to facilitate rotation of the rotating rod 11. Preferably, the gap between the rotating rod 11 and the insertion hole 131 is greater than or equal to the diameter of the pull rope 12 and less than or equal to the diameter of the rotating rod 11. This prevents the gap from being too small, making it difficult for the pull rope 12 to move, and also prevents the gap from being too large, causing the pull rope 12 to move excessively and collide with the insertion hole 131, thus resulting in force loss. The diameter of the pull rope 12 is preferably 1-8 mm; when the pull rope 12 is made of tough steel wire rope, the diameter can be slightly smaller, preferably 1-5 mm; when the pull rope 12 is made of nylon rope or hemp rope, the diameter needs to be larger, preferably 3-8 mm.

[0050] Furthermore, the raised strip 13 is provided with a through hole corresponding to the pull rope 12; one end of the pull rope 12 is connected to the rotating rod 11 and passes through the through hole to protrude outside the torsion device 1, while the other end of the pull rope 12 is connected to the insertion hole 131; this facilitates pulling the exposed part of the pull rope 12 to drive the rotating rod 11 to rotate, thereby pulling the insertion strip to bend along the direction of the rotating rod 11.

[0051] The through-hole preferably includes an inlet hole and an outlet hole, allowing one end of the pull rope 12 to protrude through the outlet hole onto the outside of the raised strip 13, or even onto the connection between the fixing strip 21 and the cover strip 22, so that pulling the pull rope 12 can drive the rotating rod 11 to rotate; while the other end of the pull rope 12 is connected to the insert strip through the inlet hole, so that pulling the pull rope 12 can drive the insert strip to move. Preferably, the end of the pull rope 12 away from the insert strip can be provided with a pull ring, so that pulling the pull ring can drive the rotating rod 11 to rotate, thereby pulling the insert strip to bend towards the rotating rod 11, so that the fixing strip 21 and the cover strip 22 are in the unlocked state.

[0052] In some embodiments, the raised strip 13 is provided with a deflector strip 132, and the pull rope 12 is guided by the deflector strip 132 and connected to the insert strip. Specifically, the deflector strip 132 is horizontally arranged, and the pull rope 12, guided along the deflector strip 132, can pull the insert strip in the vertical direction, causing the insert strip to bend in the vertical direction. This allows the insert strip to bend with less force, improving unlocking efficiency.

[0053] The inlet and outlet holes can be located on the same side of the deflector bar 132, or on opposite sides of the deflector bar 132. This allows the pull rope 12 to be connected to the rotating rod 11 and then pulled through the outlet hole, or connected to the insert bar through the inlet hole. The inlet and outlet holes fix the position and direction of movement of the pull rope 12, preventing it from shifting. Preferably, the inlet and outlet holes are located on opposite sides of the deflector bar 132 to prevent friction between the inlet and outlet portions of the pull rope 12, thus affecting the transmission of force.

[0054] Reference Figure 3 The second embodiment of this application also provides a prefabricated wall panel installation structure, including the splicing installation component described in any one of the first embodiments and its implementation methods. The splicing installation component is fixedly connected to the wall 5, and is used to fix and install the wall panel, that is, the wall panel can be fixedly installed on the wall 5 by means of the splicing installation component.

[0055] Wall panels can be placed above and below the cover strip 22 of the splicing installation component, thereby splicing identical or different wall panels. At the same time, the tightness of the engagement between the insert strip and the fixing strip 21 can be adjusted by the pull rope 12 and the rotating rod 11, thereby adjusting the splicing tightness between two wall panels. In addition, the insert strip and the fixing strip 21 can be quickly installed and removed in the installed and unlocked states, making the splicing between wall panels more convenient, faster, and saving time and costs. It is suitable for occasions that require frequent disassembly or replacement of wall panels, such as exhibition centers, chain stores, etc.

[0056] Specifically, the splicing and installation components are fixedly connected to the wall 5 via the fixing strip 21; after the cover strip 22 and the fixing strip 21 are engaged, the gap between the cover strip 22 and the fixing strip 21 is used to place the wall panel, thereby fixing the position of the wall panel. The fixing method can be screw connection, bolt connection, etc.

[0057] The prefabricated wall panel installation structure of this embodiment can adjust the tightness of the engagement between the cover strip 22 and the fixing strip 21 by the torsion device 1, thereby fixing the wall panel on the wall 5.

[0058] Reference Figure 4 and Figure 5 In some embodiments, the prefabricated wall panel installation structure further includes a retaining strip 6, which is located above or below the splicing installation assembly and is connected to the fixing strip 21. After being connected to the fixing strip 21, the retaining strip 6 abuts against the bottom or top of the wall panel placed on the fixing strip 21, thereby fixing the position of the wall panel.

[0059] Furthermore, a placement cavity is formed between the clip 6 and the splicing assembly, and the placement cavity is used to place the wall panel. Specifically, a placement cavity is formed between the clip 6, the fixing strip 21, and the cover strip 22 to place and fix the wall panel.

[0060] The two ends of the clip 6 are provided with connecting parts 62 and abutting parts 61, so that the clip 6 is in the shape of "U". The connecting parts 62 are used to connect with the wall 5 or the fixing strip 21, thereby fixing the position of the clip 6. The connecting parts 62 may be provided with positioning holes 621, through which the clip 6 is connected with the wall 5 or the fixing strip 21. Specifically, bolts, screws, etc. can be used to pass through the positioning holes 621 to fix it to the wall 5 or the fixing strip 21.

[0061] A wall panel can be placed between the connecting part 62 and the abutting part 61 to fix the position of the wall panel. Specifically, the abutting part 61 corresponds to the cover strip 22 and both abut against the surface of the wall panel, allowing the wall panel to slide out from the placement cavity.

[0062] When the clip 6 is located at the lower edge of the wall 5, the opening of the "U"-shaped clip 6 faces upward; when the clip 6 is located at the lower edge of the wall 5, the opening of the "U"-shaped clip 6 faces downward; this facilitates alignment with the cover strip 22, thereby fixing the position of the wall panel.

[0063] The wall panel may include a decorative wall panel 3 and a seismic-resistant panel 4. Specifically, the seismic-resistant panel 4 may be located between the fixing strip 21 and the decorative wall panel 3 to improve the seismic resistance of the wall panel.

[0064] In summary, the splicing installation component and prefabricated wall panel installation structure provided in this application include a splicing strip and a torsion device. The splicing strip is fixed by a snap-fitting insert on the cover strip to achieve a locked state. The torsion device is located in the gap and can be turned by rotating the rotating rod to pull the pull rope, thereby causing the insert connected to the pull rope to bend in the direction close to the rotating rod, that is, to bend the insert away from the fixed strip, reducing the tightness of the connection between the insert and the fixed strip until the insert and the fixed strip are separated, achieving an unlocked state. In this state, the splicing installation component can be quickly and non-destructively disassembled. When the pulling force on the pull rope disappears, the insert returns to its original shape and snaps back onto the fixed strip. That is, the splicing installation component of this application can be disassembled and reused, which is simple and quick to operate and reduces costs.

[0065] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing examples, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions in the examples of this application.
