Description

Technical Field

[0001] The utility model relates to the technical field of building curtain wall construction, in particular to a building curtain wall positioning device. Background Art

[0002] Curtain walls are the exterior coverings of buildings, providing not only an aesthetically pleasing appearance but also thermal insulation and heat preservation. These curtain walls can be constructed from a variety of materials, including metal, stone, concrete, or glass. Glass curtain walls are a popular architectural decorative material due to their transparency and modern aesthetic.

[0003] After extensive searching, the publication number CN212224686U discloses an auxiliary positioning device for building curtain walls. By providing a rotating rod and a positioning plate, the curtain wall can be assisted in positioning and installation, making installation more convenient. The connecting rod and gear can make the rotating rod more stable and avoid the rotating rod from detaching, making it easy to use.

[0004] In the existing technology, adjacent curtain wall glasses can be limited when in use, so that the angle between the diagonal curtain wall glasses can be kept constant during construction. However, in actual use, it is found that although the angle between the diagonal curtain wall glasses is kept constant, the device in the existing technology cannot effectively clamp the curtain wall glasses during curtain wall glass installation, resulting in that after the curtain wall glasses are positioned and installed, the stability between the curtain wall glasses and the wall connecting components cannot be effectively guaranteed, and there is a risk of the curtain wall glasses falling off. Therefore, a building curtain wall positioning device is needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a building curtain wall positioning device, which has the advantages of improving the stability of the installation structure after the curtain wall glass is positioned, avoiding the curtain wall glass from falling off or shifting, and solving the problem of poor connection stability between the curtain wall glass and the wall connecting member after the device in the prior art positions and installs the curtain wall glass.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a building curtain wall positioning device, comprising a first clamping frame and a second clamping frame, wherein the first clamping frame and the second clamping frame are fixedly connected by expansion bolts, the first clamping frame and the second clamping frame form a 90-degree angle with each other, and curtain wall glass is clamped at four corners on opposite sides of the first clamping frame and the second clamping frame;

[0007] The first clamping frame includes a first limiting plate, a first limiting block is embedded and installed in the middle of the upper end surface of the first limiting plate, first limiting strips are fixedly installed on the upper end surfaces of the first limiting plate on both sides of the first limiting block, and a first limiting groove is formed on the upper end surface of the first limiting block perpendicular to the first limiting strip;

[0008] The second clamping frame includes a second limiting plate, a groove is formed in the middle of the lower end surface of the second limiting plate and a second limiting block is embedded and installed, second limiting strips are fixedly installed on the lower end surfaces of the second limiting plate on both sides of the second limiting block, and a second limiting groove is formed on the lower end surface of the second limiting block perpendicular to the second limiting strip;

[0009] The two first limiting strips are movably inserted into the second limiting groove at opposite ends, and the two second limiting strips are movably inserted into the first limiting groove at opposite ends.

[0010] Preferably, the length and width of the first stopper plate match those of the second stopper plate. The first and second stopper plates are designed to perfectly match each other. This consistency ensures perfect docking of the two clamping frames during assembly, improving the stability and symmetry of the overall structure. This design simplifies the installation process, as the matching dimensions reduce the need for adjustment and alignment.

[0011] Preferably, the diameter of the first limit block is smaller than the width of the first limit plate, and a first reserved hole is provided at the center of the first limit block. The inner wall of the first reserved hole is coaxial with the opposite ends of the two first limit bars. In the design, the diameter of the first limit block is intentionally designed to be smaller than the width of the first limit plate. This design allows adjacent curtain wall glass to be limited by the first limit block. The provision of the first reserved hole enables the first limit block to be precisely aligned with the first limit bar on the same axis, thereby ensuring the precise positioning of the curtain wall glass during installation.

[0012] Preferably, the two first limiting strips are provided with first through holes at equal distances, and the cross section of the first through holes is designed to be elliptical. In the design, the first through holes at equal distances on the first limiting strips are designed to be elliptical, which provides a larger glue injection space.

[0013] Preferably, the upper end surface of the second limiting plate is provided with four filling slots in a rectangular array, and all four filling slots are designed with a rectangular structure. In the design, the four filling slots on the upper end surface of the second limiting plate are designed with a rectangular array. This structure optimizes the use of the plate and provides a channel for glue injection.

[0014] Preferably, the diameter of the second limit block is smaller than the width of the second limit plate. A second pre-set hole is defined at the center of the second limit block, and the inner wall of the second pre-set hole is coaxial with the opposite ends of the two second limit bars. The diameter of the second limit block is designed to be smaller than the width of the second limit plate, similar to the design of the first limit block, ensuring that the gap size between adjacent curtain wall glass remains unchanged. The provision of the second pre-set hole enables the second limit block to be precisely aligned on the same axis as the second limit bar, further ensuring positioning accuracy.

[0015] Preferably, the two second limit bars are equidistantly provided with second through holes, and the cross-section of the second through holes is designed to be elliptical. In the design, the second through holes equidistantly provided on the second limit bar are designed to be elliptical, which echoes the design of the first through holes and provides the same glue injection space.

[0016] Preferably, the expansion bolt passes through the first and second pre-set holes, and a first and second gasket are flexibly mounted on the expansion bolt. The upper end surface of the first gasket contacts the first clamping frame, and the lower end surface of the second gasket contacts the upper end surface of the second clamping frame. The design of the expansion bolt allows it to pass through the first and second pre-set holes, ensuring a secure connection between the two limit blocks and the corresponding clamping frames. The flexibly mounted design of the first and second gaskets provides additional support and cushioning for the expansion bolt, ensuring close contact between the clamping frame and the wall, and enhancing the stability of the overall structure.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The utility model forms a stable clamping structure by using a first clamping frame and a second clamping frame at a 90-degree angle to each other and fixedly connected by expansion bolts. This design provides better support during installation and reduces the risk of curtain wall glass being displaced by external forces. Curtain wall glass is clamped at the four corners on the opposite sides of the first and second clamping frames. This layout ensures a more stable connection between the curtain wall glass and the wall connecting member after installation, thereby reducing the risk of falling off. The design of the first and second limit blocks, and their use in conjunction with the first and second limit bars, provide a precise positioning function. This coordination relationship between the limit block and the limit strip can ensure the precise alignment and fixation of the curtain wall glass during the installation process, further enhancing the stability of the overall structure. The design of the first limit plate and the second limit plate, and their coordination with the limit block and the limit strip, not only provides stability, but also provides glue injection space, so that the structural glue can be filled into the gap, thereby enhancing the connection strength between the curtain wall glass and the clamping frame. The design of the expansion bolt allows it to pass through the first reserved hole and the second reserved hole, and is movably equipped with the first gasket and the second gasket. This design provides additional support and buffering for the expansion bolt, ensures close contact between the clamping frame and the wall, and enhances the stability of the overall structure. In summary, this building curtain wall positioning device effectively improves the stability of the curtain wall glass after installation and reduces the risk of falling off or displacement through its unique design and structure.

In the design, the four filling slots 211 on the upper end surface of the second limiting plate 21 are designed in a rectangular array.

[0036] Preferably, the diameter of the second limit block 212 is smaller than the width of the second limit plate 21.

[0038] Example 3

[0039] In order to provide additional support and cushioning through the expansion bolts and make the clamping frame in close contact with the wall, such as Figure 1 and Figure 4 As shown, in this embodiment, the expansion bolt 3 passes through the first reserved hole 1112 and the second reserved hole 2122. The expansion bolt 3 is movably fitted with a first gasket 31 and a second gasket 32. The upper end surface of the first gasket 31 contacts the first clamping frame 1, and the lower end surface of the second gasket 32 ​​contacts the upper end surface of the second clamping frame 2. The design of the expansion bolt 3 allows it to pass through the first reserved hole 1112 and the second reserved hole 2122, ensuring a stable connection between the two limit blocks and the corresponding clamping frames. The movably fitted design of the first gasket 31 and the second gasket 32 ​​provides additional support and cushioning for the expansion bolt 3, ensuring close contact between the clamping frame and the wall, and enhancing the stability of the overall structure.

At this time, the curtain wall glass is placed on the two first limit bars 12 on the first clamping frame 1, and the second clamping frame 2 is installed on the front side of the first clamping frame 1 away from the wall through the second reserved hole 2122, and the second gasket 32 ​​is fitted on the expansion bolt 3, and the first gasket 32 ​​is tightened by tightening the nut. A clamping frame 1 is fixedly connected to a second clamping frame 2, and the first limiting bar 12 is inserted into the second limiting groove 2121, and the second limiting bar 22 is inserted into the first limiting groove 1111, thereby achieving the fixation of the curtain wall glass. After the curtain wall glass is fixedly installed, the gap between adjacent curtain wall glasses is the cross-sectional size of the first limiting block 111 and the second limiting block 212. At this time, structural adhesive can be injected into the gap through the filling groove 211, and due to the setting of the first through hole 121 and the second through hole 221, the first clamping frame 1 and the second clamping frame 2 can be more tightly connected to the curtain wall glass through the structural adhesive.
