Technical Field

[0001] This utility model relates to the field of building technology, specifically to a high-precision curtain wall installation structure for prefabricated buildings. Background Technology

[0002] Prefabricated buildings refer to buildings in which some or all of the building components are prefabricated in a factory, then transported to the construction site and assembled using reliable connection methods. These prefabricated components can include walls, floors, stairs, balconies, beams and columns, etc. They are manufactured in factories according to standardized and industrialized production methods, and have the advantages of stable quality, high precision and high production efficiency.

[0003] Prefabricated building curtain wall installation structure is a structure used to reliably connect prefabricated curtain wall components to the main building structure and quickly assemble them on site. It typically includes prefabricated curtain wall panels, connection nodes, and sealing systems.

[0004] However, the existing prefabricated building curtain wall installation structure has low precision. When installing the curtain wall, it is necessary to manually align the connection nodes on the curtain wall with the connection nodes on the prefabricated building that has already been assembled. Therefore, it does not meet the current requirements. In response, we propose a high-precision curtain wall installation structure for prefabricated buildings. Utility Model Content

[0005] The purpose of this utility model is to provide a high-precision curtain wall installation structure for prefabricated buildings, in order to solve the problems mentioned in the background art, such as the low precision of existing prefabricated building curtain wall installation structures and the need to manually align the connection nodes on the curtain wall with the connection nodes on the already assembled prefabricated building during installation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The high-precision curtain wall installation structure for prefabricated buildings includes two side panels for installing prefabricated building curtain walls. The key technical point is that a strip groove is provided in the middle of the outer surface of each of the two side panels, and multiple strip mounting grooves located on the front and rear ends of the side panels are provided in front of and behind the strip grooves. A positioning hemispherical block is fixed inside the strip mounting groove.

[0007] An aluminum alloy plate for curtain wall fixing is provided between the strip mounting groove on the rear end face of the first side panel from left to right and the corresponding strip mounting groove on the front end face of the second side panel. Metal rods are fixed to both ends of the upper side and both ends of the lower side inside the aluminum alloy plate. Springs are movably sleeved on the outer surface of the metal rods. One end of the spring is connected to a metal sleeve that is movably sleeved on the outer surface of the metal rod. A positioning sleeve is fixed between two corresponding metal sleeves. The side of the positioning sleeve facing the nearest side panel has a hemispherical groove, and the positioning sleeve is movably sleeved on the outer surface of the positioning hemispherical block through the hemispherical groove.

[0008] The positioning sleeve is provided with a positioning mounting groove. One side of the positioning mounting groove is provided with an internal threaded through hole located on the outer surface of the side plate. The position of the internal threaded through hole corresponds to the position of the positioning mounting groove, and the corresponding internal threaded through hole and the positioning mounting groove are provided with mounting bolts.

[0009] Furthermore, one side of the positioning sleeve is provided with a metal sleeve located on the outer surface of the aluminum alloy plate. Inside the metal sleeve is a threaded fixing rod that is connected to the aluminum alloy plate by a threaded structure, and a fixing head is fixed to the surface of the threaded fixing rod facing the nearest positioning sleeve.

[0010] Furthermore, the positioning hemispherical block is hemispherical in shape, and the shape of the inner wall of the hemispherical groove corresponds to the shape of the positioning hemispherical block.

[0011] Furthermore, the surface of the fixing head facing the nearest positioning sleeve is a plane, and multiple anti-slip stripes are provided on the plane of the fixing head facing the positioning sleeve.

[0012] Furthermore, a sealing plate is provided behind the aluminum alloy plate, and the cross-sectional shape of the aluminum alloy plate corresponds to the shape of the sealing plate.

[0013] Furthermore, the outer surface of the aluminum alloy plate is in contact with the inner wall of the strip mounting groove, and the aluminum alloy plate and the strip mounting groove are slidably connected.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The glass curtain wall 1 (model GK-H8888), spring 9 (model JX110), and mounting bolt 14 (model DIN912) mentioned in this utility model can all be obtained from the market or through private customization.

[0022] Example 1

[0023] Please see Figures 1 to 3 An embodiment of this utility model is provided: a high-precision curtain wall installation structure for prefabricated buildings, including two side plates 1 for installing prefabricated building curtain walls. A strip groove 13 is provided in the middle of the outer surface of each of the two side plates 1. Multiple strip installation grooves 4 are provided in front of and behind the strip groove 13, respectively located on the front and rear ends of the side plate 1. A positioning hemispherical block 5 is fixed inside the strip installation groove 4.

[0024] An aluminum alloy plate 3 for curtain wall fixing is provided between the strip mounting groove 4 located at the rear end face of the first side plate 1 from left to right and the corresponding strip mounting groove 4 at the front end face of the second side plate 1. Metal rods 8 are fixed at both ends of the upper side and the lower side inside the aluminum alloy plate 3. Springs 9 are movably sleeved on the outer surface of the metal rods 8. One end of the springs 9 is connected to a metal sleeve 10 movably sleeved on the outer surface of the metal rods 8. A positioning sleeve 6 is fixed between the two corresponding metal sleeves 10. The side of the positioning sleeve 6 facing the nearest side plate 1 has a hemispherical groove 7, and the positioning sleeve 6 is movably sleeved on the outer surface of the positioning hemispherical block 5 through the hemispherical groove 7.

[0025] The positioning sleeve 6 has a positioning mounting groove 16 on the outer surface of the aluminum alloy plate 3 on both its upper and lower sides. One side of the positioning mounting groove 16 has an internally threaded through hole 15 on the outer surface of the side plate 1. The position of the internally threaded through hole 15 corresponds to the position of the positioning mounting groove 16, and a mounting bolt 14 is installed inside both the corresponding internally threaded through hole 15 and the positioning mounting groove 16. The positioning hemispherical block 5 is hemispherical in shape, and the shape of the inner wall of the hemispherical groove 7 corresponds to the shape of the positioning hemispherical block 5. The outer surface of the aluminum alloy plate 3 fits against the inner wall of the strip mounting groove 4, and the aluminum alloy plate 3 and the strip mounting groove 4 are slidably connected. When the glass curtain wall 2 needs to be installed, the front and rear ends of the two aluminum alloy plates 3 fixed to the upper and lower end faces of the glass curtain wall 2 are inserted axially into the four strip mounting grooves 4 located on the outer surfaces of the two side plates 1. During insertion... The positioning sleeve 6 located inside the aluminum alloy plate 3 will come into contact with the positioning hemispherical block 5 fixed on the outer surface of the strip mounting groove 4. When the two come into contact, due to the continuous insertion action, the positioning sleeve 6 will be forced to slide outward. During the outward movement of the positioning sleeve 6, the metal sleeve 10 fixed to it will move outward together and squeeze the spring 9 connected to it. When the hemispherical groove 7 on the outer surface of the positioning sleeve 6 is exactly aligned with the positioning hemispherical block 5, the reaction force of the squeezed spring 9 can push the positioning sleeve 6 back, so that the positioning hemispherical block 5 can automatically be inserted into the hemispherical groove 7 to form a mechanical lock, thereby completing the initial positioning and limiting of the aluminum alloy plate 3 as a whole. After the aluminum alloy plate 3 is positioned by the positioning hemispherical block 5 and the positioning sleeve 6, the positioning mounting groove 16 on its outer surface will be aligned with the internal thread through hole 15 on the outer surface of the side plate 1.

[0026] The above technical solution enables the positioning and mounting groove 16 used to fix the glass curtain wall 2 to be automatically aligned with the internal threaded through hole 15 located on the outer surface of the side plate 1, thereby providing a precise reference for subsequent fastening operations and improving the accuracy of assembling the glass curtain wall 2.

[0027] Once the aluminum alloy plate 3 is positioned, the fixing bolts 14 are screwed into the positioning mounting groove 16 through the internal threaded through hole 15 to fix the aluminum alloy plate 3. When the aluminum alloy plate 3 is fixed, the glass curtain wall 2 that is fixed to it will also be fixed together.

[0028] A metal sleeve 10 is provided on one side of the positioning sleeve 6, located on the outer surface of the aluminum alloy plate 3. Inside the metal sleeve 10 is a threaded fixing rod 11 connected to the aluminum alloy plate 3 via a threaded structure. A fixing head 12 is fixed to the face of the threaded fixing rod 11 facing the nearest positioning sleeve 6. The face of the fixing head 12 facing the nearest positioning sleeve 6 is flat, and multiple anti-slip stripes are provided on the flat surface of the fixing head 12 facing the positioning sleeve 6. When the aluminum alloy plate 3 is positioned as a whole by the positioning hemisphere 5 and the positioning sleeve 6, before fixing it with the mounting bolts 14, the inner part of the metal sleeve 10 located on the outer surface of the aluminum alloy plate 3 is rotated. The threaded fixing rod 11 of the part, through the threaded structure between the aluminum alloy plate 3 and the threaded fixing rod 11, will move back and forth when the threaded fixing rod 11 is rotated. At this time, the threaded fixing rod 11 is moved towards the positioning sleeve 6 that is closest to it. As the threaded fixing rod 11 moves, the fixing head 12 that is fixed to it will also be pushed towards the positioning sleeve 6. When the fixing head 12 and the positioning sleeve 6 are completely fitted, the positioning sleeve 6 can be fixed. This prevents the positioning sleeve 6 from moving left and right under the action of external force, which would cause the position of the internal threaded through hole 15 and the positioning mounting groove 16 to deviate.

[0029] A sealing plate 17 is provided behind the aluminum alloy plate 3, and the cross-sectional shape of the aluminum alloy plate 3 corresponds to the shape of the sealing plate 17. After the aluminum alloy plate 3 is fixed as a whole, the sealing plate 17 is fixed to the outer surface of the aluminum alloy plate 3 by bolts to cover the gap on the outer surface of the aluminum alloy plate 3 and ensure the airtightness of the assembled structure.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
