Description

Technical Field

[0001] This invention relates to a method for connecting a curtain wall to the main building structure, specifically an adjustable through-type fixed connection method for curtain wall panels, which is a method for connecting curtain wall connectors through the exterior wall of a building inside the building. Background Technology

[0002] A curtain wall is a non-load-bearing, lightweight wall structure commonly used in modern large and high-rise buildings for decorative purposes. It consists of panels and a supporting structural system, and can have a certain degree of displacement relative to the main structure or its own deformation capacity. It is an external building envelope or decorative structure that does not bear the load of the main structure.

[0003] Currently, most curtain walls are connected to the exterior of the building. According to the current connection method, the installation of the curtain wall needs to be carried out on the outside of the building. Workers need to use high-altitude equipment to install the curtain wall, which increases the safety hazards of the operation. Moreover, it is difficult for workers to accurately position the curtain wall on the equipment, which affects the appearance of the building facade. In addition, the curtain wall is connected to the building on the outside, and the gap required between the two is large. A large gap will reduce the actual usable space.

[0004] Chinese patent application 202110455437.4 discloses an embedded movable curtain wall connection structure, including a concrete floor slab, a brick structure, a concrete structure, an outer frame, movable curtain wall connection components, fixed curtain wall connection components, a glass curtain wall, and a stone curtain wall. The brick structure is fixed to the upper surface of the front edge of the concrete floor slab, and the concrete structure is integrally fixed to the upper end of the brick structure. The brick structure and concrete structure formed at the front edge of the concrete floor slab can serve as railings. However, this invention has many components and requires wet work.

[0005] Chinese patent application 202221833533.4 discloses a connection structure for building curtain walls. This structure includes a connection structure, a curtain wall connection plate, a wall connection plate, a connecting block, a connecting hole, a screw, a nut, a limiting structure, a limiting groove, a limiting block, a horizontal limiting block, and a vertical limiting block. The limiting structure enables rapid docking and positioning of the curtain wall connection plate and the wall connection plate, facilitating pre-installation and connection and fixation of the connecting block. The screw and nut connect and fix the connecting block, thus achieving the connection and fixation of the curtain wall connection plate and the wall connection plate. A buffer structure, a buffer seat, a piston, buffer filler, and a push rod are included, with the push rod connected to both ends of the wall connection plate, providing a buffering and shock-absorbing effect. However, this invention requires connection work on the exterior surface of the building, resulting in a large gap. Workers must perform construction on the outside of the building, raising safety concerns. Summary of the Invention

[0006] This invention provides an adjustable through-type fixing connection method for curtain wall panels. Workers can stand in the internal passage of the building to fine-tune and fix the curtain wall panels of this invention, eliminating the need for outdoor installation using a suspended platform and ensuring construction safety. Moreover, the curtain wall is connected inside the building, saving the gap between the curtain wall panels and the outside of the building.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0008] S1. Reserve exterior wall openings on the exterior wall of the main building and embed steel plates around the reserved exterior wall openings. The embedded steel plates are equipped with protruding screws and matching bolts around their perimeter. The cross-sectional area of ​​the reserved exterior wall openings is larger than the cross-sectional area of ​​the connecting end of the curtain wall connector.

[0009] S2. Construction hoisting tools lift the integrated curtain wall panels and curtain wall connectors, insert the connecting end of the curtain wall connectors into the reserved external wall holes, and workers standing in the passageway inside the main building install curtain wall panel fine-tuning devices to temporarily fix the curtain wall panels and curtain wall connectors, and perform fine-tuning and calibration.

[0010] S3. Weld the curtain wall fasteners to the connecting ends of the curtain wall connectors and the embedded steel plates respectively, so that the curtain wall panels are connected and fixed to the main building structure.

[0011] S4. Remove the curtain wall panel fine-tuning device and reuse it.

[0012] In S2, when the curtain wall panel fine-tuning device consists of four fine-tuning angle steels, pre-drilled bolt slots on the four sides of the curtain wall connector end, and fine-tuning bolts that match the pre-drilled bolt slots, workers standing in the passageway inside the main building insert the protruding screws around the embedded steel plate into the screw holes on the fine-tuning angle steels and tighten them with bolts. This fixes the fine-tuning angle steels to the embedded steel plate in the four directions (up, down, left, right). The enlarged head of the fine-tuning bolt is inserted into the pre-drilled bolt slot, and the other end of the fine-tuning bolt is tightened onto the fine-tuning angle steel with a nut. The position of the curtain wall connector can be adjusted by adjusting the position of the nuts on the four fine-tuning angle steels. After fixing, the four fine-tuning angle steels and fine-tuning bolts can be disassembled and reused.

[0013] In S2, when the curtain wall panel fine-tuning device consists of a fine-tuning robotic arm with an electromagnet and a connecting steel plate, the connecting steel plate is welded and fixed to the end of the curtain wall connector. Workers standing in the main building's internal passageway magnetically fix the electromagnet of the fine-tuning robotic arm to the connecting steel plate. The position of the curtain wall connector can be adjusted by changing the position of the fine-tuning robotic arm. After being fixed, the fine-tuning robotic arm can be disassembled and reused.

[0014] In S3, the curtain wall fastener is a panel with three or more sides. One side of the curtain wall fastener is welded to the connecting end of the curtain wall connector, and its adjacent side is welded to the embedded steel plate, so that the curtain wall panel is connected and fixed to the main building structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. Traditional methods of connecting curtain wall panels to the building structure involve connectors and fasteners located on the exterior of the building, occupying a significant amount of space and reducing usable floor space. In the connection method of this invention, the curtain wall panels are fixedly connected inside the building by penetrating the exterior wall of the main structure. The curtain wall connectors and fasteners are moved inside the building, reducing the gap between the curtain wall panels and the exterior of the main structure and increasing usable floor space.

[0017] 2. Traditional curtain wall panels are connected to the building structure from the outside. Workers must operate outdoors on the outside of the building to position and install the panels. When the installation height is high, climbing equipment is needed. However, workers standing on this equipment are prone to swaying, making accurate panel positioning difficult and posing significant safety hazards. Using the connection method of this invention, a crane lifts the curtain wall panel. After the panel and connectors are temporarily fixed through the building's exterior wall, workers can perform minor adjustments, bolting, and welding from inside the building's walkways, avoiding the safety hazards of outdoor high-altitude work.

[0018] 3. The connection structure involved in this invention is simple, the materials are easy to obtain, the components can be manufactured in a standardized manner, the precision is high and the assembly is easy, and it can be widely used in building curtain wall installation.

Detailed Implementation

[0028] To better understand the present invention, the invention will be further described below with reference to the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0029] Example 1

[0030] Figure 1-3This diagram illustrates the application and installation of an adjustable through-type fixed connection method for curtain wall panels according to the present invention (angle steel adjustment type). The connection method in this embodiment involves a curtain wall panel connection node including a curtain wall panel 1. One end of a square hollow curtain wall connector 2 is fixedly connected to the inner side of the curtain wall panel 1 (the side closest to the building's main exterior wall 6). The inner connecting end of the curtain wall connector 2 passes through a reserved exterior wall hole 5 on the building's main exterior wall 6. The cross-section of the reserved exterior wall hole 5 is slightly larger than the cross-section of the curtain wall connector 2. An embedded steel plate 51 is provided in the inner side of the building's main exterior wall 6. The embedded steel plate 51 is a square steel plate with a square hole in the middle. The size of the hole is the same as the size of the reserved exterior wall hole 5 (so the connecting end of the curtain wall connector 2 extends into the reserved exterior wall hole, and at the same time, it also extends into the embedded steel plate 51). The embedded steel plate 51 is equipped with protruding screws 52 and bolts adapted to the protruding screws 52 on its top, bottom, left, and right sides. The curtain wall connector 2 has four reserved bolt grooves 21 on its connecting end, each groove containing a fine-tuning bolt 3. The enlarged head of the fine-tuning bolt 3 is locked within the groove. The width of the reserved bolt groove 21 is slightly larger than the diameter of the screw of the fine-tuning bolt 3, but smaller than the diameter of the fixed end of the fine-tuning bolt 3. Fine-tuning angle steel 7 is provided on the four outer sides of the connecting end of the curtain wall connector 2. The fine-tuning angle steel 7 is fixed by the protruding screws 52, bolts, and fine-tuning bolts 3 around the embedded steel plate 51. One end of the fine-tuning bolt 3 with the fixed enlarged head is connected to the curtain wall connector 2. The position of the curtain wall connector 2 is adjusted by adjusting the nut on the other movable end of the fine-tuning bolt 3. The four fine-tuning bolts 3 correspond to the top, bottom, left, and right directions respectively. Fine-tuning of the curtain wall panel 1 in the front-to-back direction is achieved by workers using jacks. The curtain wall panel fine-tuning device involved in this connection method includes fine-tuning angle steel 7, reserved bolt grooves 21 on the four sides of the curtain wall connector connection end, and fine-tuning bolts 3 that are adapted to the reserved bolt grooves.

[0031] The edges at the four corners of the connecting end of the curtain wall connector 2 are connected and fixed to the embedded steel plate 51 via the curtain wall fastener 4. The curtain wall fastener 4 is a polygonal steel plate, with one side welded and fixed to the edges at the four corners of the connecting end of the curtain wall connector 2, and the adjacent sides welded to the embedded steel plate 51 along the diagonal direction. All welds are fillet welds, and both sides of the plate are welded.

[0032] The connection method in this embodiment is as follows:

[0033] S1. An external wall hole 5 is reserved on the main building exterior wall 6, and a steel plate 51 is embedded around the reserved external wall hole 5. The embedded steel plate 51 has protruding screws 52 and matching bolts around it. The cross-sectional area of ​​the reserved external wall hole 5 is slightly larger than the cross-sectional area of ​​the connecting end of the curtain wall connector 2.

[0034] S2. Construction hoisting tools lift the integrated curtain wall panel 1 and curtain wall connector 2, extending the connecting end of the curtain wall connector 2 into the reserved external wall hole 5, and also into the middle of the embedded steel plate 51. The curtain wall panel fine-tuning device consists of four fine-tuning angle steels 7, reserved bolt slots 21 on the four sides of the connecting end of the curtain wall connector 2, and fine-tuning bolts 3 that are compatible with the reserved bolt slots 21. Workers standing in the passageway inside the main building extend the protruding screws 52 around the embedded steel plate 51 into the fine-tuning angle steels 7. The screw holes on the upper part are tightened with bolts, and the fine-adjustment angle steel 7 is fixed in the four directions of up, down, left and right of the embedded steel plate 51. The enlarged head of the fine-adjustment bolt 3 is inserted into the reserved bolt groove 21, and the other end of the fine-adjustment bolt 3 is tightened on the fine-adjustment angle steel 7 with a nut. The position of the curtain wall connector 2 can be adjusted by adjusting the position of the nuts on the four fine-adjustment angle steels 7 to achieve fine-adjustment calibration. The same fixing operation is performed on all four fine-adjustment angle steels 7. The fine adjustment in the front and back direction of the curtain wall panel 1 is achieved by workers using jacks.

[0035] S3. The curtain wall fastener 4 is a polygonal plate. One side of each of the four curtain wall fasteners 4 is welded to the connecting end of the curtain wall connector 2, and the adjacent sides are welded to the embedded steel plate 51, so that the curtain wall panel 1 is connected and fixed to the building's main exterior wall 6. The four connectors 2 of each curtain wall panel 1 are fixed in the same way.

[0036] S4. After being fixed, the four fine-tuning angle steels 7 and fine-tuning bolts 3 can be disassembled and reused.

[0037] Example 2

[0038] like Figure 4-7 As shown, the difference between this connection method and Embodiment 1 lies in S2 and S4:

[0039] In S2, when the curtain wall panel fine-tuning device is a fine-tuning robotic arm 8 with an electromagnet 10 and a robotic arm connecting steel plate 9, the robotic arm connecting steel plate 9 is welded and fixed to the end of the curtain wall connector 2. After the worker standing in the passage inside the main building magnetically fixes the electromagnet 10 of the fine-tuning robotic arm 8 to the robotic arm connecting steel plate 9, the position of the curtain wall connector 2 can be adjusted by moving the position of the fine-tuning robotic arm 8.

[0040] In S4, once fixed in place, the micro-adjustment robotic arm 8 can be detached and used cyclically.

[0041] In practice, based on the manufacturing process of the curtain wall panel 1 and the weight limit of the lifting equipment, the spacing between the four curtain wall connectors 2 of a single curtain wall panel 1 is 3 meters in the horizontal direction and 2 meters in the vertical direction. The spacing of the corresponding reserved external wall holes 5 is matched with the curtain wall connectors 2.

[0042] The scope of protection of this invention is not limited to the specific embodiments described above. Based on common technical knowledge and conventional methods in the field, other equivalent modifications, substitutions or alterations can be made to this invention without departing from the basic technical concept described above, and all such modifications or alterations fall within the scope of protection of this invention.
