Description

Technical Field

[0001] This utility model relates to a fixing and installation device, and more particularly to a fixing and installation device for the exterior curtain wall of a building, belonging to the field of design and manufacturing technology of installation process equipment for exterior wall accessories of buildings. Background Technology

[0002] A curtain wall is the exterior wall cladding of a building. It is non-load-bearing and hangs up like a curtain, hence the name "curtain wall". It is a lightweight wall structure with decorative effect commonly used in modern large and high-rise buildings. It consists of panels and a supporting structural system. It can have a certain displacement capacity relative to the main structure or a certain deformation capacity itself. It is an exterior building envelope or decorative structure that does not bear the load of the main structure.

[0003] Existing positioning devices for curtain wall installation, such as the patent with publication number CN219011646U, include a horizontal column and a positioning device. Two support frames are fixedly connected to both ends of the horizontal column. A pre-embedded frame is provided on the side of the horizontal column close to the support frames. The positioning device includes a threaded column, which is connected through to the upper end of the support frame. A positioning plate is movably connected to one end of the threaded column inside the support frame. A threaded sleeve that mates with the support frame is provided on the outer wall of the threaded column. Thus, the positioning plate wraps and positions the curtain wall, providing support and positioning for the curtain wall, facilitating effective installation. Furthermore, the threaded fixing reduces the tools required for curtain wall installation, increasing the flexibility of the device, allowing for repeated use of the curtain wall, and reducing installation costs. The aforementioned positioning device for curtain wall installation fixes the curtain wall panels by clamping them. The positioning plate clamps the upper and lower sides of the curtain wall, which results in an excessively large gap between two adjacent curtain wall panels. This not only affects the aesthetics but also increases the wind load and affects the overall stability of the curtain wall. Utility Model Content

The connecting installation structure is movably arranged in the connecting installation mechanism composed of each plug-in end plate through the mounting holes. Each plug-in end plate inserted into the slot is detachably connected to the slot through the connecting installation structure with each connection hole.

[0010] Furthermore, the connection and installation mechanism also includes two plug-in side plates and a top sealing plate. The two plug-in end plates, the two plug-in side plates, and the top sealing plate constitute an open installation box. The installation box is fixed to the steel installation base plate through its open end.

The connecting block 2 and the fixing support base are detachably connected as a whole through the connecting installation structure. The projections of the sequentially arranged connecting block 2, connecting installation structure, and fixing support base on the building wall are all smaller than the projection of the exterior curtain wall 1 on the building wall at the corresponding position. The technical solution provided in this application is based on the exterior curtain wall. It constructs a fixed installation device by adding connecting blocks, connecting installation structures, and fixed support bases. The connecting blocks are detachably fixed to the inner surface of the exterior curtain wall, and the fixed support bases are detachably fixed to the designated positions on the building surface where the exterior curtain wall needs to be installed. Finally, the connecting blocks and fixed support bases are detachably connected as a whole through the connecting installation structures. During the installation process, the projections of the sequentially arranged connecting blocks, connecting installation structures, and fixed support bases onto the building wall are all smaller than the projections of the exterior curtain wall onto the corresponding building wall surfaces. This ensures that adjacent exterior curtain wall panels can be arranged close together or even in tight contact after installation, effectively eliminating the problem of large gaps between adjacent exterior curtain wall panels installed with existing installation devices. This effectively reduces or even avoids the occurrence of installation gaps, thereby significantly reducing the wind load on the exterior curtain wall and ensuring its stability and safety.

[0023] In light of the actual conditions at the installation site, and for ease of installation, this application provides an installation connection mechanism on the connection mounting surface of the connecting block 2. The connecting block 2 is detachably fixed to the inner side of the outer curtain wall 1 via the side without the installation connection mechanism, in cooperation with the fixing block 4.

The connecting mounting structure is movably arranged in the connecting mounting mechanism composed of each plug-in end plate through the mounting holes 10. Each plug-in end plate inserted into the slot 5 is detachably connected to the slot 5 through the connecting mounting structure with each connecting hole 6. In a preferred embodiment, the connection and installation mechanism further includes two plug-in side plates and a top sealing plate. The two plug-in end plates, the two plug-in side plates, and the top sealing plate constitute an open installation box. The installation box is fixed to the steel installation base plate through its open end. The connection and installation structure, which is movably arranged in the installation box through the installation holes 10, detachably connects the slot 5 and the installation box into a whole with the cooperation of each installation hole 10.

[0024] Furthermore, as a key component of this application's improvement, in order to simplify its structure and facilitate compatibility with the connection and installation mechanism of the mounting box structure, the connection and installation structure of this application includes at least a support guide assembly, a connection fixing assembly, and an adjustment mounting assembly. The connection end of the connection fixing assembly, which is movably arranged in the mounting box through the support guide assembly in cooperation with the mounting hole 10, can extend out of the mounting box. The adjustment mounting assembly is hinged to the two end plates of the mounting box through the mounting hole 10, and the connection fixing assembly is movably arranged on the adjustment mounting assembly. The slot 5 and the mounting box are detachably connected as a whole through the adjustment mounting assembly driving the connection fixing assembly in cooperation with the connection hole 6. For ease of installation, the connection and installation structure of this application also includes a limiting block 11. The connection and fixing assembly includes two movable seats 12 and four limiting mounting rods 13. The four limiting mounting rods 13 are divided into two groups and arranged on the outside of the two movable seats 12 respectively. The limiting block 11 is arranged in the middle of the mounting box through the support and guide assembly. The four limiting mounting rods 13 of the two movable seats 12 are arranged outward in the mounting box on both sides of the limiting block 11 through the support and guide assembly. During the connection between the slot 5 and the mounting box, the free ends of the four limiting mounting rods 13 are respectively inserted into the connecting holes 6 through the two movable seats 12 with the cooperation of the support and guide assembly and the adjustment mounting assembly, so that the slot 5 and the mounting box are detachably connected as a whole. More specifically, the support and guide assembly of this application includes three guide rods 14. The limiting block 11 is arranged in the middle of the mounting box through the middle guide rod 14 and the mounting hole 10. Two movable seats 12 are respectively arranged in the mounting box on both sides of the limiting block 11 through the other two guide rods 14 and the mounting hole 10. The two movable seats 12 can reciprocate along the length of the two guide rods 14 under the drive of the adjustment mounting assembly. The adjustment mounting assembly includes a bidirectional screw 15 and two sets of butterfly knobs 16. Each mounting seat 3 is provided with a threaded hole with the thread direction corresponding to the corresponding end of the bidirectional screw 15. The two ends of the bidirectional screw 15 passing through the limiting block 11 are respectively hinged to the two end plates of the mounting box through the mounting hole 10. The two sets of butterfly knobs 16 are respectively fixed on the free ends of the bidirectional screw 15 extending out of the two end plates of the mounting box. The two movable seats 12 are respectively threaded to the corresponding ends of the bidirectional screw 15 through their respective threaded holes.

[0025] In summary, the technical solution provided in this application also has the following advantages:

[0026] With the above-described structure, this invention utilizes the connection block, curtain wall body, slot, mounting base, bidirectional threaded rod, rotating assembly, movable base, limiting rod, through hole, limiting hole, and mounting assembly for installation. During curtain wall body installation, the connection block is first installed on one side of the curtain wall body. Then, the mounting base is fixed to the wall surface using the mounting assembly. Next, the connection block is inserted into the outer side of the mounting base via the slot. When the mounting base is inserted to the innermost part of the slot, the through hole aligns with the corresponding limiting hole. Finally, the bidirectional threaded rod is rotated via the rotating assembly, driving the two movable bases to move simultaneously in opposite directions. This causes the limiting rod to pass through the through hole and limiting hole, thus limiting and fixing the connection block and curtain wall body, making the installation of the curtain wall body more secure. Furthermore, the installation structure of this device is located on one side of the curtain wall body, preventing interference with the installation of adjacent curtain wall bodies. This allows adjacent curtain wall bodies to fit snugly without large gaps, thereby improving the overall stability of the curtain wall.

[0027] The technical solution of this application will be further described below through specific embodiments:

[0028] This utility model provides a curtain wall installation and positioning device that solves the problem of excessive gaps between adjacent curtain wall panels, which affects aesthetics, increases wind load, and compromises the overall stability of the curtain wall. It makes the installation of the curtain wall body more secure. Furthermore, the installation structure of this device is located on one side of the curtain wall body, so it does not affect the installation of adjacent curtain wall panels. This allows adjacent curtain wall panels to be installed snugly without large gaps, thereby improving the overall stability of the curtain wall.

[0029] To achieve the above objectives, this utility model provides the following technical solution:

[0030] A positioning device for curtain wall installation includes a connecting block. A curtain wall body is detachably mounted on one side of the connecting block. A slot is provided on the side of the connecting block away from the curtain wall body. A mounting seat is movably inserted into the slot. A cavity is provided inside the mounting seat. A horizontally arranged bidirectional threaded rod is rotatably connected to the cavity. The bidirectional threaded rod is located outside the slot. A rotating assembly connected to the bidirectional threaded rod is provided on the outside of the mounting seat. Two movable seats are symmetrically arranged inside the cavity. The movable seats are threadedly connected to the bidirectional threaded rod. A limiting rod is fixedly connected on the side of the two movable seats that are far apart from each other. Through holes corresponding to the limiting rods are provided on both sides of the inner wall of the cavity. Limiting holes corresponding to the limiting rods are provided on both sides of the outer wall of the mounting seat. An installation assembly is provided on the side of the mounting seat away from the connecting block.

[0031] Each of the four corners of the connecting block is fixedly connected to a fixing block, and fixing screws are inserted between the fixing block and the curtain wall body.

[0032] The rotating assembly includes a connecting rod integrally formed at both ends of a bidirectional threaded rod, one end of which passes through the mounting base and is fixedly connected to a butterfly knob.

[0033] Several guide rods are fixedly connected to the inner wall of the cavity. Each guide rod is arranged parallel to the bidirectional threaded rod, and the movable seat is slidably connected to the guide rod.

[0034] A limiting block is fixedly connected to the center of the cavity. When the two movable seats are in contact with the two sides of the limiting block, the limiting rod is just inserted into the through hole.

[0035] The installation assembly includes mounting plates fixedly connected to the four corners of the mounting base, and the mounting plates have horizontal mounting holes through the side facing the curtain wall body.

[0036] Example 1

[0037] like Figure 1-5 As shown, a positioning device for curtain wall installation includes a connecting block. A curtain wall body is detachably mounted on one side of the connecting block. A slot is provided on the side of the connecting block away from the curtain wall body. A mounting seat is movably inserted into the slot. A cavity is provided inside the mounting seat. A horizontally arranged bidirectional threaded rod is rotatably connected to the cavity. The bidirectional threaded rod is located outside the slot. A rotating assembly connected to the bidirectional threaded rod is provided on the outside of the mounting seat. Two movable seats are symmetrically arranged inside the cavity. The movable seats are threadedly connected to the bidirectional threaded rod. A limiting rod is fixedly connected on the side of the two movable seats that are far apart from each other. Through holes corresponding to the limiting rods are provided on both sides of the inner wall of the cavity. Limiting holes corresponding to the limiting rods are provided on both sides of the outer wall of the mounting seat. An installation assembly is provided on the side of the mounting seat away from the connecting block. When installing the curtain wall body, first install the connecting block on one side of the curtain wall body, then fix the mounting base on the wall surface with the cooperation of the mounting components, and then insert the connecting block into the outside of the mounting base with the cooperation of the slot (at this time, the limiting rod is located in the cavity and through hole, which does not affect the insertion of the mounting base into the slot). When the mounting base is inserted to the innermost side of the slot, the through hole will be aligned with the corresponding limiting hole. Finally, by rotating the bidirectional threaded rod with the rotating component, the two moving seats move in opposite directions at the same time, thereby driving the limiting rod to pass through the through hole and the limiting hole, thus limiting and fixing the connecting block and the curtain wall body.

[0038] Each of the four corners of the connecting block is fixedly connected to a fixing block, and a fixing screw passes through the fixing block and the curtain wall body. The connecting block is detachably connected to the curtain wall body through the cooperation of the fixing screw and the fixing block.

[0039] The rotating assembly includes a connecting rod integrally formed at both ends of a bidirectional threaded rod. The connecting rod allows the butterfly knob to be positioned closer to the outside, making it easier for installers to rotate. One end of the connecting rod passes through the mounting base and is fixedly connected to a butterfly knob for rotating the bidirectional threaded rod. Both sides are provided with butterfly knobs, allowing installers to rotate the bidirectional threaded rod from both sides, making it easier for installers to use and improving the convenience of the device.

[0040] Several guide rods are fixedly connected to the inner wall of the cavity. Each guide rod is arranged parallel to the bidirectional threaded rod. The movable seat is slidably connected to the guide rod. By setting multiple guide rods, the movable seat can be more stable when moving horizontally, and will not rotate or shake. This allows the limiting rod to be inserted into the through hole more accurately.

[0041] A limiting block is fixedly connected to the center of the cavity, which limits the movement of the two movable seats on both sides. When the two movable seats are in contact with the two sides of the limiting block, the limiting rod is just inserted into the through hole.

[0042] The installation assembly includes mounting plates fixedly connected to the four corners of the mounting base. The mounting plates have horizontal mounting holes through the side facing the curtain wall body. When installing the mounting base, bolts are inserted into the mounting holes to fix the mounting to the wall surface.

[0043] In use, first install the connecting block on one side of the curtain wall body, then fix the mounting base on the wall surface through the cooperation of the mounting plate, mounting holes and bolts. Then, insert the connecting block into the outside of the mounting base through the cooperation of the slot (at this time, the limiting rod is located in the cavity and through hole, which does not affect the insertion of the mounting base into the slot). When the mounting base is inserted to the innermost side of the slot, the through hole will be aligned with the corresponding limiting hole. Finally, rotate the bidirectional threaded rod by the butterfly knob to drive the two moving seats to move in opposite directions at the same time, thereby driving the limiting rod to pass through the through hole and the limiting hole, thus limiting the connection block and the curtain wall body, and completing the fixed installation of the curtain wall body.
