Description

Technical Field

[0001] This utility model relates to the field of exterior wall panel installation technology, specifically to a prefabricated light steel composite exterior wall panel connection structure. Background Technology

[0002] The connection structure between the light steel composite exterior wall panels and the wall surface is a core component in ensuring the safety, stability, and comfort of a building. Its function extends beyond bearing external forces; it also includes maintaining the stability, earthquake resistance, sound and heat insulation, and waterproofing of the wall structure. Through a well-designed connection system, it can effectively distribute the effects of wind pressure and earthquakes, preventing the exterior wall panels from detaching or deforming, while ensuring the airtightness of the gaps between the panels, thus maintaining excellent sound and heat insulation performance. In terms of design, the connection structure between the light steel composite exterior wall panels and the wall surface typically employs various methods such as bolt connections, pin connections, reinforced concrete connections, hook connections, or magnetic snap-fit ​​connections. These methods are chosen based on the building height, the surrounding environment, and the characteristics of the exterior wall panels. When choosing a connection method, bolted connections are common and easy to install; pin connections are suitable for edge areas; reinforced concrete connections can enhance load-bearing capacity; hook connections are suitable for modular construction; and magnetic or snap-fit ​​connections are suitable for lightweight walls, offering advantages such as quick disassembly and maintenance. However, current connection structures primarily function at a single point on the bottom of the lightweight steel composite exterior wall panel. This concentration of connections at a single point on the bottom of the panel reduces the number of connecting components and simplifies construction. However, as an exterior wall structure, the lightweight steel composite exterior wall panel is subject to significant external loads (such as wind pressure and earthquakes), especially in high-rise buildings. The load borne by the exterior wall panel includes not only its own weight but also stresses from wind pressure and temperature changes. In a single-point connection design at the bottom, all loads are concentrated at one connection point, resulting in a very large load on that single point. This can easily lead to excessive local stress, and given the large area of ​​the lightweight steel composite exterior wall panel, connection point failure or deformation can occur. Utility Model Content

[0003] The purpose of this utility model is to provide a prefabricated light steel composite exterior wall panel connection structure. The hanging beam is fixed to the outer wall of the wall by L-shaped back support and expansion bolts, while the bottom edge of the light steel exterior wall panel is placed in the support cavity of the T-arm and bolted. At this time, in the length direction of the light steel exterior wall panel, the beginning and end ends of multiple hanging beams are fixed by a double tube positioning structure to support the light steel exterior wall panel, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated light steel composite exterior wall panel connection structure, including a hanging beam and an integrally formed T-arm on one side of the hanging beam, wherein a support cavity is provided between the T-arm and the hanging beam for the bottom edge of the light steel composite exterior wall panel to enter, and two symmetrical and equal-length L-shaped back supports are integrally formed on the other side of the hanging beam, an expansion bolt for connecting with the wall is installed on one side of the outer wall of the L-shaped back support, a convex groove is provided between the two L-shaped back supports, a reinforcing part for connecting with the hanging beam is provided on the outer wall of the T-arm near the convex groove, and a double-tube positioning structure is provided at both ends of the hanging beam, the double-tube positioning structure being used to fix the beginning and end ends of two adjacent hanging beams.

[0005] Preferably, a second C-shaped seat and a rectangular protrusion are fixed at both ends inside the convex groove, and the interior of the second C-shaped seat is provided with a rectangular hollow cavity for the rectangular protrusion to be inserted into.

[0006] Preferably, a U-shaped plate is welded to the outer wall of the second C-port near the reinforcing part, and a positioning pin is installed on the outer wall of the U-shaped plate away from the second C-port for bolting to the end of the rectangular protrusion.

[0007] Preferably, the reinforcing part includes a protrusion integrally formed on the outer wall of one side of the T-arm and a first C-shaped seat fixed on both sides inside the convex groove. One end of the protrusion extends into the interior of the convex groove and is inserted into the two first C-shaped seats.

[0008] Preferably, the dual-tube positioning structure includes two hollow columns integrally formed at one end of the hanging beam and two docking slots provided at the other end of the hanging beam, wherein the docking slots are used for inserting the hollow columns.

[0009] Preferably, one end of the hollow column is provided with a fully penetrating positioning hole, and the top and bottom walls of the hanging beam are provided with internal threaded through holes. After the hollow column is inserted into the docking groove, the positioning hole and the internal threaded through hole are in a concentric state.

[0010] Preferably, a flat-shank external threaded pin is installed inside the internal threaded through hole. After the positioning hole and the mating groove are inserted, the flat-shank external threaded pin is used to screw into the positioning hole and the hollow column.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This prefabricated light steel composite exterior wall panel connection structure uses hanging beams fixed to the outer wall of the wall via L-shaped back supports and expansion bolts. The bottom edge of the light steel exterior wall panel is placed in the support cavity of the T-arm and bolted on. Furthermore, multiple hanging beams are fixed at both ends along the length of the light steel exterior wall panel using a double-tube positioning structure, thus providing overall support for the light steel exterior wall panel. The hanging beams, fixed to the outer wall of the wall via L-shaped back supports and expansion bolts, ensure the even distribution of multiple support points, effectively reducing the burden on a single connection point. In this way, the load borne by the exterior wall panel is not concentrated locally, but distributed through multiple hanging beams, improving the overall load-bearing capacity of the structure. The combination of the T-arm support cavity and hanging beams provides more stable support for the light steel exterior wall panel, forming multiple support points along the length of the wall panel, rather than relying solely on a single connection point at the bottom. The double-tube positioning structure ensures the fixed position of the hanging beams, further enhancing the overall stability of the light steel exterior wall panel. Whether subjected to wind pressure, gravity loads, or vibrations caused by factors such as earthquakes, multiple connection points and support points can work together to improve the stability of the exterior wall panels, avoid the tilting or swaying of the exterior wall panels that may be caused by a single connection point, further increase the horizontal support of the exterior wall panels, reduce the relative displacement of the exterior wall panels, and enable the wall panels to maintain better stability during long-term use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5 This utility model provides an embodiment of a prefabricated light steel composite exterior wall panel connection structure, including a hanging beam 1 and a T-arm 2 integrally formed on one side of the outer wall of the hanging beam 1. A support cavity 201 for the bottom edge of the light steel composite exterior wall panel to enter is provided between the T-arm 2 and the hanging beam 1. Two symmetrical and equal-length L-shaped back supports 3 are integrally formed on the other side of the outer wall of the hanging beam 1. An expansion bolt 4 for connecting with the wall is installed on one side of the outer wall of the L-shaped back support 3. A convex groove 101 is provided between the two L-shaped back supports 3. A reinforcing part 5 for connecting with the hanging beam 1 is provided on the outer wall of the T-arm 2 near the convex groove 101. A double-tube positioning structure 8 is provided at both ends of the hanging beam 1. The double-tube positioning structure 8 is used to fix the beginning and end ends of two adjacent hanging beams 1.

[0020] The two ends of the convex groove 101 are respectively fixed with a second C-shaped seat 6 and a rectangular protrusion 7. The second C-shaped seat 6 has a rectangular hollow cavity 601 for the rectangular protrusion 7 to be inserted into. A U-shaped plate 602 is welded to the outer wall of the second C-shaped seat 6 near the reinforcing part 5. A positioning pin 603 is installed on the outer wall of the U-shaped plate 602 away from the second C-shaped seat 6 to be bolted to the end of the rectangular protrusion 7. After the two adjacent hanging beams 1 are connected, the end of the rectangular protrusion 7 enters the rectangular hollow cavity 601 of the second C-shaped seat 6, and the end plane of the rectangular protrusion 7 contacts the inner wall surface of one side of the U-shaped plate 602. Then, the workers can use the positioning pin 603 to tighten the U-shaped plate 602 and the rectangular protrusion 7 again to further tighten the connection between the beginning and end of the two adjacent hanging beams 1.

[0021] The reinforcing part 5 includes a protrusion 502 integrally formed on one side of the outer wall of the T-arm 2 and first C-shaped seats 501 fixed on both sides inside the convex groove 101. One end of the protrusion 502 extends into the interior of the convex groove 101 and is inserted into the two first C-shaped seats 501. The protrusion 502 is integrally formed on the outer wall of the T-arm 2 near the convex groove 101. The protrusion 502 is located between the two first C-shaped seats 501. Through the combined action of multiple connection points and the first C-shaped seats 501 and the protrusion 502, the seismic performance of the exterior wall panel is effectively improved. When the exterior wall panel is subjected to horizontal load, the deformation of the exterior wall panel can be dispersed through multiple support points to avoid excessive local stress and stress concentration.

[0022] The double-tube positioning structure 8 includes two hollow spiral-shaped columns 801 integrally formed at one end of the hanging beam 1 and two mating grooves 803 provided at the other end of the hanging beam 1. The mating grooves 803 are used for the hollow spiral-shaped columns 801 to be inserted into. One end of the hollow spiral-shaped column 801 is provided with a fully penetrating positioning hole 802. The top and bottom walls of the hanging beam 1 are provided with internal threaded through holes. After the hollow spiral-shaped column 801 is inserted into the mating groove 803, the positioning hole 802 and the internal threaded through hole are in a concentric state. A flat-handled external threaded pin 9 is installed inside the internal threaded through hole. After the positioning hole 802 and the mating groove 803 are inserted, the flat-handled external threaded pin 9 is used to screw into the positioning hole 802 and the hollow spiral-shaped column 801.

[0023] When two adjacent hanging beams 1 are connected, the worker inserts the hollow column 801 at the end of one hanging beam 1 into the positioning hole 802 at the end of the other hanging beam 1 until the ends of the two adjacent hanging beams 1 are connected. At this time, the positioning hole 802 is concentric with the holes on the top and bottom walls of the hanging beam 1, that is, the positioning hole 802 is concentric with the flat shank external threaded pin 9. Then the worker manually rotates the flat shank external threaded pin 9 until the end of the flat shank external threaded pin 9 is screwed into the positioning hole 802, thus achieving a stable connection between the two hanging beams 1.

[0024] Before installation, the materials used in this embodiment are inspected to ensure that all components are complete and meet quality standards. The construction site is also cleaned to ensure a safe environment. The installation positions of the hanging beams 1 are then determined by marking the outer wall of the wall to identify the installation points for each hanging beam 1. The ends of adjacent hanging beams 1 are connected using a double-pipe positioning structure 8 to secure them together and form a unified structure. This process continues until the support length of the multiple hanging beams 1 is approximately equal to the length of the light steel composite exterior wall panel. Finally, the assembled hanging beams 1 are secured with expansion bolts. 4. The L-shaped back support 3 is fixed to the outer wall of the wall. During this process, holes need to be pre-drilled on the outer wall of the wall. At the same time, the workers should use a level and a plumb line to make accurate measurements to ensure that the installation position of the hanging beam 1 is accurate. After the hanging beam 1 is stably fixed, the workers put the bottom edge of the light steel structure composite exterior wall panel into the support cavity 201 between the T-arm 2 and the hanging beam 1. At this time, the hanging beam 1 and the T-arm 2 can fully support the bottom edge of the exterior wall panel to avoid uneven support. The exterior wall panel can also be fixed to the T-arm 2 with bolts until multiple exterior wall panels are fixed on the hanging beam 1 and the T-arm 2 in the same way.
