DETAILED DESCRIPTION

[0032] The application will be further described in detail below in combination with the drawings and specific embodiments:

[0033] The embodiment 1 aims to provide a traceless connecting device for fabricated building wall, which is mainly used for the combination connection between fabricated walls, and further improves the structural strength between adjacent walls. Fabricated building has the advantages of fast construction speed, controllable quality, energy saving and environmental protection, etc., so it has been widely used in modern building field. As an important part of fabricated building wall, it usually relies on bolts, welding and other ways, and the design and performance of its connecting device directly affect the safety and stability of the whole building. In view of the problems of weak connection strength and stability, insufficient flatness and aesthetics between the fabricated walls in the prior art, the embodiment provides a traceless connecting device for fabricated building wall, which can combine and assemble adjacent walls through the connecting device, so that the connection part has no obvious trace, the appearance is neat and beautiful, and the connection strength and stability of the wall can be ensured, thereby improving the application range and practicality of the device.

[0034] As shown in Figures 1-5 , the connecting device provided by the embodiment comprises a combination wall 1, a connecting wall and a moving buckle mechanism 4, the moving buckle mechanism comprises a plug-in seat 41, a lead screw 42, a positioning rod 43, an upper clamping seat 44, a lower clamping seat 45, an upper locking block 35 and a lower locking block 39, wherein the plug-in seat 41 is fixed on the side of the combination wall, and in the embodiment, the plug-in seat is composed of two horizontal plates parallel to each other and a vertical stand plate in the middle. The lead screw 42 is vertically rotatably installed between the upper and lower horizontal plates, the lead screw is a reverse threaded lead screw, and a guide sleeve 46 is matched and sleeved at the connection between the upper and lower parts of the lead screw and the plug-in seat, so as to ensure the stability of the lead screw during rotation. And the top of the lead screw extends out of the upper horizontal plate of the plug-in seat, and is provided with a driving source. The driving source can be a driving motor or a hand wheel assembled with the lead screw by threads, and the rotation of the lead screw is driven by the driving source.

[0035] As shown in Figure 2 and Figure 5 , a positioning rod 43 parallel to the lead screw is also fixed on the plug-in seat, specifically, a plug-in groove matching the outer diameter of the positioning rod is arranged on the upper and lower horizontal plates of the plug-in seat, for matching and plug-in fixing of the positioning rod. Referring to Figure 5 , the upper and lower clamping seats 44 and 45 are correspondingly connected by threads at the upper and lower parts of the lead screw, and coaxial positioning holes 47 are formed in the upper and lower clamping seats, so that the upper and lower clamping seats can be sleeved on the positioning rod. The upper and lower clamping seats are respectively provided with an upward upper clamping head 441 and a downward lower clamping head 451 at the end away from the lead screw, and an inclined surface 48 is respectively arranged downward and upward on the side adjacent to the positioning rod on the upper and lower clamping heads, and the inclined surfaces on the upper and lower clamping heads match the inclined surfaces on the upper and lower locking blocks.

[0036] As shown in Figure 1 and Figure 2As shown, the connecting wall can be fixed to the ground through the base, and the base includes a base and a column in this embodiment. The top surface of the base is vertically provided with a plurality of columns, and each column extends upward into the interior of the main cavity 2 to support the connecting wall. The height of the column can be adjusted adaptively according to the height of the wall, or whether the base is installed in the connecting wall can be adaptively selected. The connecting wall includes a main cavity 2 and a side cavity 3, as shown in Figure 4 and Figure 6 As shown, the side cavity is symmetrically fixed to the left and right sides of the main cavity through connecting bolts. The side cavity is provided with a plug-in slot 31. The plug-in slot includes an upper insertion hole 311, a mounting cavity 312, and a lower insertion hole 313. The upper insertion hole and the lower insertion hole are symmetrically arranged along the horizontal direction, and the height of the upper insertion hole and the lower insertion hole matches the thickness of the horizontal plate of the plug-in seat to match the plug-in of the upper and lower horizontal plates of the plug-in seat. The mounting cavity is located between the upper insertion hole and the lower insertion hole, and the hollow interior of the mounting cavity is connected to the side plate of the main cavity. An avoidance slot 32 is respectively formed in the upper insertion hole and the lower insertion hole. The inner diameter of the avoidance slot is slightly larger than the outer diameter of the positioning rod and the lead screw, so that when the plug-in seat of the moving buckling mechanism is moved and plugged into the side cavity, the avoidance slot avoids interference with the lead screw and the positioning rod.

[0037] Locking grooves 31 are respectively formed in the left side of the upper insertion hole and the left side of the lower insertion hole. The upper locking block 35 and the lower locking block 39 are respectively slidably fitted in the upper and lower locking grooves. The upper locking block and the lower locking block are the same structure, and the side close to the main cavity is respectively provided with an inclined surface 37 downward and upward. An opening is respectively provided in the lower left of the upper locking groove and the upper left of the lower locking groove, which is an active interval 36 for inserting the upper clamp head and the lower clamp head, so that the upper clamp head and the lower clamp head can be in contact with the inclined surface on the upper locking block and the lower locking block.

[0038] When the plug-in seat is buckled and installed in the plug-in slot of the connecting wall, the lead screw is controlled to rotate, which drives the axial movement of the upper clamp head and the lower clamp head, and then drives the upper clamp head and the lower clamp head to push the upper locking block and the lower locking block to move horizontally in the corresponding locking groove. When the upper locking block and the lower locking block move horizontally to the right side surface and contact with the inner wall of the locking groove, the rotation of the lead screw is stopped, and the upper clamp head and the lower clamp head are no longer moved upward or downward. The locking of the end position of the upper locking block and the lower locking block is realized through the locking wire 38, and the upper clamp head and the lower clamp head are respectively fixedly connected with the upper locking block and the lower locking block. Finally, the adjacent combined wall is fixedly combined through the connecting wall.

[0039] Working principle: the traceless connecting device for fabricated building wall provided in this embodiment works. Referring to Figure 7The plug-in socket 41 on the combined wall is aligned with the upper and lower insertion holes 311 and 313 of the side cavity 3 of the connecting wall to ensure smooth insertion of the plug-in socket; at this time, the lead screw 42 and the positioning rod 43 pass through the avoidance slot 32 and are not hindered, and the driving source (such as a rotating hand wheel or a starting motor) of the lead screw 42 is started to rotate the lead screw. Since the lead screw is designed with reverse threads, the upper and lower clamping seats 44 and 45 will move vertically relative to each other along the direction of the lead screw.

[0040] With the movement of the upper and lower clamping seats 44 and 45, the clamping heads 441 and 451 thereon enter the active interval 36 of the upper and lower locking grooves, respectively, and contact the inclined surfaces 37 of the upper and lower locking blocks 35 and 39. The clamping heads continue to move and push the locking blocks in the locking grooves to translate horizontally through the inclined surfaces until the right side surfaces of the locking blocks contact the inner walls of the locking grooves to reach the locking position. After the locking blocks reach the final position, they are fixed by the locking wire 38 or other locking mechanisms to prevent them from retracting. At the same time, the upper and lower clamping heads are also fixedly clamped with the upper and lower locking blocks, respectively, to achieve stable connection.

[0041] In addition, in order to make the combined wall and the connecting wall more flat, after the connecting wall and the combined wall are fixedly connected together, the cover plate 25 can be fixedly installed on the top surface of the connecting wall by means of countersunk screws, and the sealing plate 26 can be fixedly installed on the front and rear side surfaces of the connecting wall by means of countersunk screws, as shown in Figure 1 This can make the top surface and the side surface of the connecting wall and the combined wall flush, and make the appearance of the assembled two more flat and beautiful. Through the above steps, the adjacent combined walls are connected by the connecting wall to achieve traceless and stable connection. The connection is clean and beautiful in appearance, without obvious traces, while ensuring the connection strength and stability of the wall.

[0042] The traceless connection device for prefabricated building walls provided in the embodiment effectively solves the problems of insufficient connection strength and stability, poor flatness and poor appearance of prefabricated walls in the prior art. The connection between walls is more firm and reliable through the cooperation of the moving clamping mechanism and the locking block, and the transverse movement and final locking of the locking block further enhance the strength and stability of the connection, ensuring that the walls will not loosen or fall off during use. The connection device is suitable for the connection of various prefabricated building walls, including walls of different materials and different specifications. Its flexible design and wide application range make the device applicable and popular in various construction projects.

[0043] In Embodiment 2, the installation structure of the main cavity is further described based on Embodiment 1.

[0044] As Figures 1-3As shown in the drawings, the main cavity 2 comprises horizontal top plates 21 parallel to each other, and two side plates 22 between the upper and lower top plates, which are perpendicular to the top plates and connected to the upper and lower top plates through sliding assemblies. Figure 1 As shown in the drawings, the sliding assembly comprises sliding rails 23 fixed to the inner walls of the upper and lower top plates in the transverse direction, and sliding blocks 24 installed on the sliding rails, the upper and lower sliding blocks being fixedly connected to the upper and lower end faces of the side plates, so that the two side plates move closer to or away from each other along the length direction of the sliding rails. Figure 3 As shown in the drawings, the end portions of the upper and lower sliding rails further extend towards the middle portions to form stop blocks 27, so as to avoid the side plates from moving out of the sliding rails during transverse sliding and to limit the movement. Figure 3 Figure 4 As shown in the drawings, the side cavity further extends outwardly on the side wall close to the main cavity to form a rectangular boss structure, so as to ensure seamless connection between the main cavity and the side cavity during assembly.

[0045] In the embodiment 3, the buffering mechanism 5 is further provided on the basis of the embodiments 1 and 2.

[0046] As shown in the drawings, the buffering mechanism cooperates with the sliding assembly in the main cavity to adjust the distance between the adjacent combined walls, and to provide buffering effect between the adjacent combined walls during an earthquake, so as to enhance the overall seismic performance of the building wall. Figure 1 Figure 8 As shown in the drawings, the buffering mechanism cooperates with the sliding assembly in the main cavity to adjust the distance between the adjacent combined walls, and to provide buffering effect between the adjacent combined walls during an earthquake, so as to enhance the overall seismic performance of the building wall.

[0047] The buffering mechanism comprises a mounting seat 51, a sleeve 52, a buffering screw 54, a connecting seat 55 and a spring 56, wherein the mounting seat is symmetrically mounted on the inner wall of the side plate 22, the sleeve is fixedly connected to the mounting seat in the transverse direction, and the other end portion of the sleeve is provided with a screw sleeve for cooperating with the buffering screw to realize the functions of rotation and transverse movement. The buffering screw is rotatably sleeved in the sleeve, and one end thereof extends outwardly and is connected to a bearing in the connecting seat; when the buffering screw rotates, the position of the buffering screw in the sleeve can be adjusted, so as to change the distance between the adjacent combined walls. The spring 56 is fixedly installed between the connecting seats of the adjacent two side plates, so that when the wall is subjected to external force, the spring can absorb and disperse energy to provide buffering effect.

[0048] ​​The working principle is that the combined walls on both sides of the main cavity are slowly driven to be inserted into the side cavities. When the left side of the upper and lower clamping heads contacts the inner side plates in the main cavity, the relative movement of the combined walls is continued, which causes the upper and lower clamping heads on both sides to press the side plates inward and causes the buffer screw to rotate. At the same time, the two side plates are continuously close, so that the distance between adjacent combined walls can be flexibly adjusted to adapt to different construction requirements or structural requirements. As the plug-in seat 41 continuously penetrates into the inside of the side cavity, the spring of the buffer mechanism is compressed, and at the same time, the spring provides an elastic force in the opposite direction to the upper and lower clamping heads. Therefore, when the control screw is rotated to drive the clamping heads and the upper and lower locking blocks to be clamped and matched, the above structure can adjust the distance between adjacent combined walls, and the cooperation of the buffer mechanism and the moving buckling mechanism can further enhance the friction between the clamping heads and the locking blocks, improve the reliability and stability of the connection, and make the clamping heads maintain close contact with the locking blocks when subjected to external impact or vibration, so as to prevent loosening or falling. On the other hand, it also provides a certain buffering and damping effect for the entire connection structure, that is, the spring can absorb and disperse part of the impact energy, reduce the damage to the building structure, and improve the seismic performance of the building. In addition, in order to improve the damping performance of the connecting wall, a shock absorber or damper can be assembled in the main cavity (the actual installation process is prior art, which is not described here), which is used in cooperation with the above buffer mechanism, thereby further improving the buffering and damping effect of the combined wall and the connecting wall assembly.

[0049] In embodiment 4, another locking structure is provided based on embodiments 1-3, which is used to lock and fix the side cavity and the moving buckling mechanism, and further improves the structural strength between the combined wall and the connecting wall.

[0050] As shown in Figure 9 and Figure 10 , an adjusting groove 73 is opened on the side of the side cavity close to the main cavity, and an adjusting block 7 is matched and assembled in the adjusting groove. The top of the adjusting block is provided with an adjusting plug plate 71, the left side of the adjusting block is provided with a slope matched with the upper and lower clamping heads, and the other side is provided with a pushing slope 72 for contacting the locking slope on the limiting block 8.

[0051] As shown in Figure 9As shown, the limiting groove 83 is arranged on the side cavity on the right side of the adjusting groove, and the limiting block 8 is matched and sleeved in the limiting groove. The limiting block 8 is provided with the locking inclined surface 82 on the side adjacent to the adjusting block. The locking screw 81 is sleeved in the limiting block. When the width of the moving buckle mechanism and the side cavity is determined, the driving source is controlled to rotate the screw rod, so that the upper clamp head and the lower clamp head are matched with the inclined surfaces on the adjacent sides of the adjusting block 7, respectively. With the vertical movement of the upper clamp head and the lower clamp head, the inclined top surface 48 on the clamp head presses and pushes the adjusting block 7 to the right side, so that the adjusting block 7 moves horizontally to the right. When the adjusting block continues to move to the right, the right side of the pushing and top surface 72 contacts the locking inclined surface on the left side of the limiting block 8, and generates upward or downward vertical pushing force, so that the limiting block moves vertically upward or downward in the limiting groove. Finally, the limiting block can be locked and fixed under the constraint of the locking screw.

[0052] The embodiment forms a stable locking structure among the adjusting block, the limiting block, the upper clamp head and the lower clamp head, so as to realize high-strength locking and fixing of the side cavity and the moving buckle mechanism. This locking mode not only effectively improves the structural strength between the combined wall and the connecting wall, but also ensures the reliability and stability of the connection. The locking structure is integrated in the side cavity, does not occupy additional space, makes the overall structure more compact, and the cooperation of multiple locking elements also makes the locking process simple and fast, improves the construction efficiency.

[0053] The above-mentioned embodiments of the present application do not constitute a limitation on the protection scope of the present application. The basic idea of the present application is to connect the adjacent combined walls together by the connecting wall, and to clamp and fix the two side cavities and the combined wall, so as to improve the structural strength between the walls, to adaptively adjust the width between the adjacent combined walls, to set the buffer mechanism to absorb and disperse the earthquake energy and reduce the impact and vibration between the walls when the earthquake and other natural disasters occur, so as to protect the integrity and stability of the building structure, and to further improve the structural strength between the combined wall and the connecting wall by cooperating with the locking structure. Any modification, equivalent replacement and improvement within the spirit and principles of the present application shall be included in the protection scope of the claims of the present application.
