[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] The embodiment of the present application provides a fixing device for partition boards, which can solve the problem in the related art that in which steel pipes are used to support both sides of two partition boards, the partition boards may fall over due to the loose fit between the steel pipes and the partition boards.

[0028] See also Figure 1 and Figure 3As shown, a fixing device for a partition board provided in an embodiment of the present application may include: a wall clamping structure 1, wherein the wall clamping structure 1 includes two clamps 11, the two clamps 11 are arranged in parallel and connected by a connecting mechanism 12, the two clamps 11 are used to clamp on opposite sides of two adjacent partition boards 3, and the two adjacent partition boards 3 can be connected using a special bonding mortar 5, at which time each clamp 11 is in contact with the two adjacent partition boards 3, and a part of each clamp 11 can also be in contact with the special bonding mortar 5; an expansion pre-buried pipe 2, wherein the expansion pre-buried pipe 2 is used to extend into the partition board 3, the expansion pre-buried pipe 2 is connected to the clamp 11 by a fixing member 4, the fixing member 4 is fixed to the expansion pre-buried pipe 2, and the expansion pre-buried pipe 2 has been extended into the partition board 3 before the fixing member 4 connects it, and the expansion pre-buried pipe 2 can be completely extended into the interior of the partition board 3, or the side close to the clamp 11 can be in the same plane as the outermost side of the partition board 3.

[0029] The embodiment of the present application sets a wall clamping structure 1 at the connection of two partition boards 3, wherein two plywoods 11 in the wall clamping structure 1 are fitted with the wall of the partition board 3, and the two plywoods 11 are connected by a connecting mechanism 12 to maintain the stability of their fitting on the partition board 3. In addition, the expansion pre-buried pipe 2 is inserted into the partition board 3, and then the fixing member 4 is inserted into the expansion pre-buried pipe 2, so that the expansion pre-buried pipe 2 utilizes the principle of compression, and while being locked between the fixing member 4 and the expansion pre-buried pipe 2, the fixing member 4 expands the expansion pre-buried pipe 2, so that the expansion pre-buried pipe 2 presses the partition board 3 and is connected and rooted with the partition board 3 to form a strong connection. Through the cooperation of the wall clamping structure 1 and the expansion pre-buried pipe 2, the partition board 3 can be effectively supported, and the two adjacent partition boards 3 can be connected as a whole, which solves the problem of using steel pipes to support the two sides of the two partition boards 3 in the related art, which may cause the partition boards 3 to fall due to the loose fit between the steel pipes and the partition boards 3. And after the installation of multiple partition boards 3 is completed, the relevant technology usually requires indoor electromechanical installation. Due to the failure to consider the electromechanical points of the wall panels, the pre-buried door stack wire pipes leading to insufficient lintel overlap, the installation of multiple wire boxes, the existence of inclined grooves or secondary grooving after omission, etc., cracks may occur at the connection between two adjacent partition boards 3. In this embodiment, the partition boards 3 can be clamped by the cooperation of two plywood plates 11 and the connecting mechanism 12, and under the action of the expansion pre-buried pipe 2 and the fixing part 4, the two adjacent partition boards 3 can be firmly connected, so that the partition boards 3 can withstand greater external forces, and can effectively prevent cracks caused by grooving and drilling of holes for electromechanical installation in the later stage while preventing overturning.

[0030] In some optional embodiments, each of the splints 11 is connected to a connecting plate 13, the two connecting plates 13 extend in a direction close to each other, and the two connecting plates 13 are connected by the connecting mechanism 12. In this embodiment, the connecting plates 13 are respectively perpendicular to the splints 11, and the two splints 11 are connected to each other in such a way that a connecting plate 13 is provided in each of the two splints 11, so that the two connecting plates 13 are connected to each other to realize an indirect connection between the two splints 11 and the connecting mechanism 12. In some other embodiments, the two splints 11 can also be directly connected to the connecting mechanism 12, and each splint 11 can also be connected to two or more connecting plates 13, and the splints 11 and the connecting plates 13 can be integrally formed, or can be connected by welding or the like.

[0031] See also Figure 2 As shown, in some optional embodiments, one of the connecting plates 13 is provided with a long hole 131, and the long hole 131 extends along the extension direction of the connecting plate 13; the connecting mechanism 12 includes an adjusting bolt 121 and a fastening nut 122 connected to the adjusting bolt 121, the adjusting bolt 121 is fixed to the other connecting plate 13, and the adjusting bolt 121 extends into the long hole 131, and the adjusting bolt 121 is fixed to any position of the long hole 131 by the fastening nut 122, that is, after the adjusting bolt 121 extends into the long hole 131, it can slide arbitrarily in the long hole 131, and after sliding to the desired position, it can be fixed by the fastening nut 122 to make the adjusting bolt 121 fixed somewhere in the long hole 131, that is, the positions of the two connecting plates 13 are determined accordingly, and the distance between the two clamping plates 11 can be adjusted by the cooperation of the adjusting bolt 121 and the long hole 131, so that the fixing device can adapt to partition boards 3 with different thicknesses. Preferably, when the adjusting bolt 121 does not extend into the long hole 131, in the connecting plate 13 where the adjusting bolt 121 is provided, the adjusting bolt 121 is detachably connected to the connecting plate 13, and a through hole may be provided in the connecting plate 13 to allow the threaded portion of the adjusting bolt 121 to penetrate therethrough. In some other embodiments, the adjusting bolt 121 may also be fixed to the connecting plate 13.

[0032] Preferably, the two connecting plates 13 are marked with scales along the extension direction of the long hole 131. Since different partition boards 3 may have different thicknesses, the distance between the two plywood 11 needs to be adjusted before using the fixing device. Marking scales in the connecting plates 13 helps the staff to quickly adjust the distance between the two plywood 11.

[0033] In some optional embodiments, the fixing device includes two expansion pre-embedded tubes 2, and the two expansion pre-embedded tubes 2 are respectively connected to the two clamps 11 through a corresponding number of fixing parts 4. In the present embodiment, each clamp 11 is connected to an expansion pre-embedded tube 2. This arrangement can make the two sides of the partition board 3 clamped by the clamps 11 more stable and less likely to tip over; in some other embodiments, the expansion pre-embedded tube 2 can be connected to only one clamp 11, or two or more expansion pre-embedded tubes 2 and a corresponding number of fixing parts 4 can be connected to each clamp 11.

[0034] Preferably, the expansion pre-embedded tubes 2 on the two clamps 11 are spaced apart along the axial direction of the expansion pre-embedded tubes 2, that is, the two expansion pre-embedded tubes 2 are spaced apart in the partition board 3 without contacting each other, and the expansion pre-embedded tubes 2 are pre-embedded by opening a placement groove in the partition board 3 and then placing the expansion pre-embedded tubes 2 in the groove. The two expansion pre-embedded tubes 2 are spaced apart so that when the placement groove is opened in the partition board 3, the partition board 3 will not be drilled through, so that the partition board 3 has a certain integrity.

[0035] In some optional embodiments, the expansion embedded tube 2 includes a plastic expansion tube 21, and the fixing part 4 includes a self-tapping screw 41. The self-tapping screw 41 is inserted into the plastic expansion tube 21, and the self-tapping screw 41 is interference fit with the plastic expansion tube 21. In this embodiment, the use of the plastic expansion tube 21 can save construction costs. In some other embodiments, other metal expansion tubes can also be used; the self-tapping screw 41 has a certain "self-tapping" property. When its tip gradually extends into the plastic expansion tube 21 and has an interference fit with the plastic expansion tube 21, the plastic expansion tube 21 is not easy to crack, and the plastic expansion tube 21 and the self-tapping screw 41 can fit closely with each other. After the self-tapping screw 41 is tightly fitted with the plastic expansion tube 21, the partition board 3 and the plywood 11 can be rigidly connected by the self-tapping screw 41.

[0036] In some optional embodiments, the clamping plate 11 is provided with a mounting hole 111, and the self-tapping screw 41 is passed through the mounting hole 111 and fixed to the plastic expansion tube 21. The mounting hole 111 is provided to facilitate the opening of a pre-buried hole for the plastic expansion tube 21. If the pre-buried hole is opened before the clamping plate 11 is clamped on the partition board 3, the position of the clamping plate 11 needs to be adjusted according to the opening position of the pre-buried hole when clamping, and the pre-buried holes on both sides of the partition board 3 are difficult to be opened directly at the same height. Therefore, the embodiment of the present application is to first fit the clamping plate 11 to the partition board 3 and then open the pre-buried hole. At this time, the mounting hole 111 is provided to facilitate the chiseling of the pre-buried hole and the placement of the plastic expansion tube 21 in the pre-buried hole. Preferably, when the plastic expansion tube 21 is completely nailed into the partition board 3 by the self-tapping screw 41, the side of the plastic expansion pre-buried tube 21 close to the clamping plate 11 just contacts the clamping plate 11.

[0037] In some optional embodiments, the mounting hole 111 extends toward the side close to the connecting mechanism 12 to form a long strip, and the self-tapping screw 41 can move in the mounting hole 111 along the extension direction of the mounting hole 111, that is, the mounting hole 111 has a longer length at this time. When opening the embedded holes, they can be opened at multiple positions of the partition board 3, which has higher structural adaptability and flexibility.

[0038] The embodiment of the present application also provides a partition board system, which includes: a plurality of partition boards 3, wherein two adjacent partition boards 3 are connected by a special bonding mortar 5; a clamping structure 1, wherein the clamping structure 1 includes two clamps 11, wherein the two clamps 11 are arranged in parallel and connected by a connecting mechanism 12, wherein the two clamps 11 are clamped on opposite sides of two adjacent partition boards 3; an expansion pre-embedded pipe 2, wherein the expansion pre-embedded pipe 2 extends into the partition board 3, wherein the expansion pre-embedded pipe 2 is connected to the clamp 11 by a fixing member 4, wherein the fixing member 4 is fixed to the expansion pre-embedded pipe 2. The partition board system may adopt the fixing device in any of the above embodiments, which will not be described herein.

[0039] In the embodiment of the present application, the distance between the clamps 11 can be adjusted automatically according to the thickness of the partition board 3, and the device has a simple structure and is easy to operate. Compared with using steel pipes for tightening, the device has higher structural adaptability and flexibility, avoiding the need for secondary treatment due to misalignment and cracking during construction, improving the installation and construction quality of the partition board 3, increasing the strength of the partition board 3 to resist external forces, and increasing the safety of the installation and construction of the partition board 3.
