Description
Technical Field
[0001] The utility model relates to the technical field of wall expansion joints, in particular to a wall expansion joint for architectural design. Background Art
[0002] In architectural design, wall expansion joints are gaps created to accommodate building deformation caused by factors such as temperature and humidity fluctuations, or foundation settlement. Their primary function is to absorb and release the pressure generated by these factors, thereby preventing cracking or deformation in structures such as walls, floors, and roofs.
[0003] The wall expansion joints of the prior art generally require that the two fixing plates be fixed to the outer walls of the two adjacent walls by two screws respectively during installation, and at the same time, the two fixing plates are fixed to the slide grooves of the C-shaped structure on the opposite side walls, and the two slide grooves are symmetrically arranged. Then, when installing the ball heads provided at both ends of the slide rod, it is necessary to insert them from the two end portions of the two slide grooves. This makes the ball heads provided at both ends of the slide rod very inconvenient to install, and the wall expansion joint has a certain length. After the ball heads at both ends of the slide rod are installed in the corresponding slide grooves, they need to slide a long distance to adapt to the installation and fixation of the cover plate, which makes the installation of the ball heads at both ends of the slide rod very inconvenient. At the same time, when the cover plate is installed, due to the rotational torque of the screws, the cover plate is prone to deflection during the locking process. Therefore, the present application provides a wall expansion joint for architectural design to meet the needs. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a wall expansion joint for architectural design to solve the problem that the ball heads at both ends of the existing sliding rod are inconvenient to install and the cover plate is easily deflected due to rotational torque when being fixed to the sliding rod by screws.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0006] A wall expansion joint for architectural design includes a wall, a sliding rod and a cover plate. Both ends of the sliding rod are fixed with ball heads. A waterstop strip for closing the wall expansion joint is provided between two adjacent walls. Both ends of the waterstop strip are fixed with fixed plates with an "inverted L-shaped" vertical cross-section. The fixing plates are fixed to the wall by two second screws respectively. A first screw is inserted into a socket provided in the middle of the cover plate. The end of the first screw is threadedly connected to a screw hole provided in the middle of the sliding rod. Convenient detachable sliding parts are installed on both of the fixing plates; and a positioning part is also included. The positioning part is installed on the convenient detachable sliding part and is connected to the fixing plate.
[0007] Optionally, both sides of the socket are provided with anti-slip lines engraved on the top of the cover plate, and the vertical section of the anti-slip lines presents a "wave-like" structure.
[0008] Optionally, both ends of the cover plate are provided with a raised portion, and the vertical cross-section of the raised portion is a "V-shaped" structure.
[0009] Optionally, the easily detachable sliding member includes a lower support plate fixed on one side wall opposite to the two fixed plates, the outer sides of the two lower support plates are movably overlapped with upper support plates, and the outer sides of the two upper support plates are fixed to the inner side wall of the cover plate through a connecting plate.
[0010] Optionally, the two upper supporting plates are combined with the lower supporting plate on the corresponding side to form a sliding groove for facilitating the sliding of the ball head, and the vertical section of the sliding groove is a "C-shaped" structure.
[0011] Optionally, the positioning parts include a plurality of connecting columns fixed on the side walls opposite to each other of the two upper support plates, and the ends of the plurality of connecting columns facing away from the upper support plates are fixed with a building block with a "circular" structure in vertical cross-section, and a plurality of building slots cooperating with the building blocks are provided at the corners of the fixed plate near the sliding rod.
[0012] Optionally, the outer sides of the insertion grooves are connected to the outside through the insertion channels, and the inner bottom walls of the insertion channels are provided with arc-shaped grooves that are adapted to the outer diameter of the connecting columns.
[0013] Optionally, the vertical cross-section of the loading groove is a "Y-shaped" structure, the outer open length of the loading groove is larger than the diameter of the building block, the inner length of the loading groove is equal to the diameter of the building block, and the thickness of the building block is equal to the width of the loading groove.
[0014] Optionally, the inner bottom wall of the mounting groove is arranged in an arc shape, and the arc shape is adapted to the outer diameter of the mounting block.
[0015] Optionally, water-blocking sealing strips are fixedly connected to inner walls at both ends of the cover plate close to the wall side walls along the length direction, and the bottom ends of the water-blocking sealing strips are movably placed on the outer side of the wall.
[0016] Compared with the prior art, the present invention has at least the following beneficial effects:
[0017] In the above scheme, by setting up a convenient detachable sliding part, when installing the ball heads provided at both ends of the sliding rod, the ball heads at both ends can be directly placed on the lower support plate on the corresponding side, and then when the cover plate is placed on the surface of the two walls, the upper support plate is simultaneously covered on the lower support plate on the corresponding side, thereby facilitating the rapid installation of the ball heads at both ends of the sliding rod. Compared with the existing technology, there is no need to insert the ball heads from the two ends of the slide groove, and there is no need to slide a long distance. It can be directly installed from the front, which greatly improves the efficiency of disassembly and assembly of the ball heads at both ends of the sliding rod.
[0018] By setting up alignment parts, that is, combining the settings of connecting columns, blocks, insertion channels, insertion grooves and arc grooves, the upper support plate can be quickly and synchronously aligned with the corresponding lower support plate when installing the cover plate. On the one hand, it avoids the deviation between the upper support plate and the lower support plate. On the other hand, it can also prevent the cover plate from being deflected during the locking process due to the rotational torque of the first screw when it is locked on the screw hole in the middle of the slide rod by the first screw, thereby effectively ensuring the quality of the cover plate after installation.
[0019] By providing anti-slip grooves, it is easier for manual hand-held cover installation to avoid the problem of unstable holding of the cover. In addition, the raised parts at both ends of the cover make it easier for construction workers to pick up and remove the cover, which makes the disassembly and installation of the cover more convenient.

[0036] like Figure 1 and Figure 7 As shown, an embodiment of the present invention provides a wall expansion joint for architectural design, including a wall 3, a sliding rod 4 and a cover plate 1, both ends of the sliding rod 4 are fixed with ball heads 41, and a waterstop 22 for closing the wall expansion joint is provided between two adjacent walls 3, and both ends of the waterstop 22 are fixed with a fixing plate 2 with an "inverted L-shaped" structure in vertical cross-section, and the fixing plate 2 is fixed to the wall 3 by two second screws 21 respectively, and a first screw 14 is inserted into the socket 15 provided in the middle of the cover plate 1, and the end of the first screw 14 is threadedly connected to the screw hole 42 provided in the middle of the sliding rod 4, and both fixing plates 2 are installed with convenient detachable sliding parts; it also includes a positioning part 5, which is installed on the convenient detachable sliding part and is connected to the fixing plate 2.
[0037] like Figure 1 and Figure 3 As shown, both sides of the insertion hole 15 are provided with anti-skid lines 11 engraved on the top of the cover plate 1, and the vertical section of the anti-skid lines 11 is a "wave-like" structure.
[0038] The anti-slip pattern 11 is provided to facilitate the operator to install and hold the cover plate 1, so as to avoid the operator from slipping due to an unstable grip of the cover plate 1 due to its flat surface.
[0039] like Figure 1 、 Figure 3 and Figure 4 As shown, both ends of the cover plate 1 are provided with a raised portion 12 , and the vertical cross-section of the raised portion 12 is a “V-shaped” structure.
[0040] Among them, the setting of the tilting part 12 enables the operator to quickly pinch the two tilting parts 12 to pick up the cover 1 when removing the cover 1, thus avoiding the problem that the two ends of the cover 1 in the prior art are flat, which makes it inconvenient to take off the cover 1.
[0041] In this embodiment, if Figures 1 to 3 As shown, in order to be able to quickly disassemble and assemble the ball heads 41 at both ends of the slide rod 4 into the slide groove, a convenient detachable sliding part is provided, including a lower support plate 23 fixed on the opposite side wall of the two fixed plates 2, and the outer sides of the two lower support plates 23 are movably overlapped with upper support plates 24, and the outer sides of the two upper support plates 24 are fixed to the inner side wall of the cover plate 1 through a connecting plate 25. The two upper support plates 24 are combined with the lower support plate 23 on the corresponding side to form a slide groove that is convenient for the ball head 41 to slide, and the vertical section of the slide groove is a "C-shaped" structure.
[0042] Among them, the shape of the slide groove is the same as that of the prior art, but the slide groove of the prior art is an integrally formed C-shaped structure, which causes the ball head 41 to be inserted from the two open ends of the slide groove. The convenient detachable sliding part mentioned in this embodiment can divide the slide groove of the prior art into two, that is, the merging of the upper support plate 24 and the lower support plate 23. In this way, the ball heads 41 at both ends of the slide rod 4 can be directly placed on the front for installation, which greatly improves the installation efficiency and does not need to be inserted from the end and then slid to adjust a large distance.
[0043] In this embodiment, if Figures 1 to 7 As shown, in order to make the upper support plate 24 and the lower support plate 23 more accurately aligned when they are matched, and to effectively avoid the problem that the cover plate 1 is not easily tightened due to the torque when it is fixed to the screw hole 42 on the slide rod 4 by the first screw 14, thereby causing the cover plate 1 to deflect, a positioning member 5 is provided, which includes a plurality of connecting columns 51 fixed on the side wall opposite to each other of the two upper support plates 24, and a plurality of connecting columns 51 are fixed on one end of the upper support plate 24 to have a "circular" structure in vertical section, and a plurality of connecting columns 51 are provided at the corner of the fixed plate 2 near the slide rod 4. The outer sides of the mounting grooves 53 that match the building blocks 52 are connected to the outside through the mounting channels 521. The inner bottom walls of the mounting channels 521 are provided with arc-shaped grooves 54 that match the outer diameter of the connecting column 51. The vertical cross-sections of the mounting grooves 53 are "Y-shaped". The outer open length of the mounting grooves 53 is larger than the diameter of the building blocks 52. The inner length of the mounting grooves 53 is equal to the diameter of the building blocks 52. The thickness of the building blocks 52 is equal to the width of the mounting grooves 53. The inner bottom wall of the mounting grooves 53 is arranged in an arc shape, and the arc shape is adapted to the outer diameter of the building blocks 52.
[0044] The outer opening length of the insertion groove 53 is larger than the diameter of the block 52, the inner length of the insertion groove 53 is equal to the diameter of the block 52, and the thickness of the block 52 is equal to the width of the insertion groove 53. This setting is to prevent the block 52 from moving in the insertion groove 53. In addition, the opening of the insertion groove 53 is provided with two symmetrically arranged inclined surfaces. This setting is to enable the block 52 to contact the inclined surfaces when it first enters the insertion groove 53. , it is quickly guided by the inclined surface into the mounting groove 53, so that the covering of the upper support plate 24 and the lower support plate 23 is very accurate and convenient, and the efficiency of alignment is improved. After the block 52 enters the mounting groove 53, the upper support plate 24 is limited, so that the cover plate 1 is installed upright on the two walls 3, and when the first screw 14 is locked in the screw hole 42 provided in the middle of the slide rod 4, the cover plate 1 can be effectively prevented from being skewed due to the rotational torque of the first screw 14.
[0045] like Figure 1 and Figure 3 As shown, water-blocking sealing strips 13 are fixedly connected to the inner walls of both ends of the cover plate 1 close to the side walls of the wall 3 along the length direction, and the bottom ends of the water-blocking sealing strips 13 are movably placed on the outer side of the wall 3.
[0046] The water-blocking sealing strip 13 can block external water stains from entering the space covered by the cover plate 1 , thereby preventing water from entering between the two walls 3 .
[0047] The working principle of the technical solution provided by the present invention is as follows: the operator first puts the water stop 22 connected between the two fixing plates 2 into the expansion joint formed between the two walls 3, and fixes the fixing plates 2 to the corresponding walls 3 by two second screws 21 respectively. After that, the ball heads 41 at both ends of the slide rod 4 are respectively placed on the lower supporting plates 23 on the corresponding side. Then, the operator holds the cover plate 1 by hand and covers the upper supporting plate 24 fixed with the connecting plates 25 symmetrically arranged on the inner wall of the cover plate 1 on the outer side of the corresponding lower supporting plate 23, so that The blocks 52 will all enter the mounting grooves 53, and cooperate with the "Y"-shaped setting of the vertical section of the mounting grooves 53, so that the upper support plate 24 and the lower support plate 23 can be quickly aligned and merged. Afterwards, the first screw 14 can be passed through the insertion hole and threadedly connected to the screw hole 42 opened in the middle of the slide rod 4. In the process of locking the first screw 14, due to the mounting design of the blocks 52 and the connecting column 51, the cover plate 1 is not prone to skew during the final tightening torque of the first screw 14, which greatly improves the efficiency and quality of disassembly and assembly.
[0048] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
