The curtain wall steel structure with a telescopic mechanism includes a steel structural beam. The beam has an internal connecting structure, which includes transmission plates on both sides of the beam. Cranks are movably connected to the left and right ends of the transmission plates via pins. A shaft is fixedly connected to the side of the cranks away from the transmission plates. This utility model utilizes the transmission plates to compress the cranks as they move inward, causing the cranks to swing from an inclined state to a vertical state. During the crank swing, the distance between the shaft and the transmission plates increases, causing a support plate connected to the shaft to move outward. When the support plate penetrates the steel structural beam and extends to the outside of the curtain wall glass, it achieves the effect of supporting and limiting the curtain wall glass, replacing the existing method of positioning the curtain wall glass through elastic contraction and preventing the glass from falling.

Description

Technical Field

[0001] This utility model relates to the field of curtain wall steel structure technology, and in particular to a curtain wall steel structure with a telescopic mechanism. Background Technology

[0002] A steel curtain wall structure is a building envelope that combines a steel structure with a curtain wall system. It combines the strength and stability of a steel structure with the aesthetics and functionality of a curtain wall. A steel curtain wall structure mainly consists of two parts: a steel frame and a curtain wall system. The steel frame serves as a support system, bearing the weight and load of the entire curtain wall and transferring the load to the main building structure through its connection with the main structure.

[0003] For example, the patent application number published on the China Patent Network is 202022601681.0, and the patent title is: A curtain wall steel structure with a telescopic mechanism. The device includes a main body, which comprises a glass curtain wall and a steel structure main body. Both ends of the glass curtain wall are fixedly connected to the steel structure main body. An adjustment mechanism is provided on the inner wall of the steel structure main body, and the adjustment mechanism includes a first slot. The upper and lower inner walls of the left side of the steel structure main body are both provided with first slots, and the upper and lower inner walls of the first slots are both provided with first sliding grooves. First sliders are slidably connected to the inner walls of four sets of first sliding grooves, and connecting rods are fixedly connected between the first sliders. First springs are fixedly connected to the left sides of two sets of connecting rods. This utility model allows the glass curtain wall to be inserted into the steel structure main body at one end before connection, making the operation simple and convenient, saving workers' time, and improving the practicality and convenience of the device.

[0004] However, the connection method between the steel structure and the glass of the curtain wall is relatively simple. The plug-in method, which uses elastic structure for elastic contraction, is prone to shaking when subjected to external vibration. When the elasticity of the elastic structure on both sides is lost, the glass is prone to separate from the steel structure and cause injury from falling objects from high altitudes. Utility Model Content

[0005] The purpose of this invention is to solve the problem of poor stability of elastic telescopic connections in the prior art, and to propose a curtain wall steel structure with a telescopic mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A curtain wall steel structure with a telescopic mechanism includes a steel structural beam. The steel structural beam has an internal connecting structure, which includes transmission plates on both sides of the beam. Each transmission plate has a crank movably connected to its left and right ends via pins. A shaft is fixedly connected to the side of the crank away from the transmission plate. The outer end of the shaft passes through the crank and extends to the outside of the crank. A support plate is fitted onto the surface of the shaft, located outside the crank. The end of the support plate away from the shaft passes through the steel structural beam and extends to the outside of the beam. The support plate and the steel structural beam are slidably connected. The steel structural beam has an internal transmission structure capable of driving the transmission plates to move horizontally.

[0008] As a preferred technical solution of this application, the transmission structure includes a bidirectional screw that is movably connected inside the steel structure beam via bearings. Both ends of the bidirectional screw pass through the transmission plate and extend to the outside of the transmission plate. The transmission plate and the bidirectional screw are threadedly connected.

[0009] As a preferred technical solution of this application, the front and rear sides of the steel structure beam are fixedly connected to vertical plates located outside the transmission plate. The vertical plates are located outside the bidirectional screw, and the outer end of the bidirectional screw passes through the vertical plate and is movably connected to the vertical plate.

[0010] As a preferred technical solution of this application, a nut is provided on the outer side of the upright plate and sleeved on the surface of the bidirectional screw, and both ends of the bidirectional screw are provided with shaped grooves.

[0011] As a preferred technical solution of this application, a guide rod is fixedly connected to the inner side of the upright plate, and the side of the guide rod away from the upright plate passes through the transmission plate and the steel structure beam. The steel structure beam is fixedly connected to the guide rod, and the transmission plate and the guide rod are slidably connected.

[0012] As a preferred technical solution of this application, the top and bottom of the steel structure beam are provided with grooves, and the grooves are located on the inner side of the support plate.

[0013] Compared with the prior art, this utility model provides a curtain wall steel structure with a telescopic mechanism, which has the following beneficial effects:

[0014] 1. This curtain wall steel structure with a telescopic mechanism, through the inward movement of the transmission plate, squeezes the crank, causing the crank to swing from an inclined state to a vertical state. During the swinging of the crank, the distance between the shaft and the transmission plate increases, causing the support plate connected to the shaft to move outward. When the support plate passes through the steel structure beam and extends to the outside of the curtain wall glass, it achieves the effect of supporting and limiting the curtain wall glass, replacing the existing step of positioning the curtain wall glass through elastic contraction, and preventing the curtain wall glass from falling.

[0015] 2. The curtain wall steel structure with telescopic mechanism can simultaneously drive multiple transmission plates to move by setting bidirectional screws, and can keep the telescopic length of multiple support plates consistent.

[0016] 3. The curtain wall steel structure with telescopic mechanism can support the bidirectional screw rod by setting up vertical plates, while improving the structural strength of the steel structure beams and reducing the contact area between the transmission structure and the external environment.

[0017] 4. The curtain wall steel structure with telescopic mechanism, by setting nuts and grooves, allows users to easily rotate the bidirectional screw, and can prevent the bidirectional screw from sliding and displacing inside the steel structure beam.

[0018] 5. The curtain wall steel structure with telescopic mechanism can limit the movement of the transmission plate by setting guide rods, thus preventing the transmission plate from tilting during movement.

[0019] 6. The curtain wall steel structure with telescopic mechanism, by setting grooves, allows users to pre-connect the glass and prevent the glass from sliding or shifting. Attached Figure Description

[0025] 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. 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 protection scope of the present utility model.

[0026] Example 1:

[0027] Reference Figure 1-4 A curtain wall steel structure with a telescopic mechanism includes a steel structure beam 1. A connecting structure 2 is provided inside the steel structure beam 1. The connecting structure 2 includes transmission plates 3 disposed on both sides inside the steel structure beam 1. Cranks 4 are movably connected to the left and right ends of the transmission plates 3 via pins. A shaft 5 is fixedly connected to the side of the crank 4 away from the transmission plates 3. The outer end of the shaft 5 passes through the crank 4 and extends to the outside of the crank 4. A support plate 6 located outside the crank 4 is sleeved on the surface of the shaft 5. The end of the support plate 6 away from the shaft 5 passes through the steel structure beam 1 and extends to the outside of the crank 4. On the outer side of the steel structure beam 1, the support plate 6 is slidably connected to the steel structure beam 1. Inside the steel structure beam 1, a transmission structure 7 is installed. The transmission structure 7 can drive the transmission plate 3 to move horizontally. As the transmission plate 3 moves inward, it presses against the crank 4, causing the crank 4 to swing from an inclined state to a vertical state. During the swinging of the crank 4, the distance between the shaft 5 and the transmission plate 3 increases, causing the support plate 6 connected to the shaft 5 to move outward. When the support plate 6 penetrates the steel structure beam 1 and extends to the outer side of the curtain wall glass, it achieves the effect of supporting and limiting the curtain wall glass. To replace the existing method of positioning curtain wall glass through elastic contraction and prevent curtain wall glass from falling, the transmission structure 7 includes a bidirectional screw 8 movably connected to the inside of the steel structure beam 1 via bearings. Both ends of the bidirectional screw 8 pass through the transmission plate 3 and extend to the outside of the transmission plate 3. The transmission plate 3 and the bidirectional screw 8 are threadedly connected. By setting the bidirectional screw 8, multiple transmission plates 3 can be moved simultaneously, and the extension and retraction lengths of multiple support plates 6 can be kept consistent. Vertical plates 9 located outside the transmission plates 3 are fixedly connected to the front and rear sides of the inside of the steel structure beam 1. The upright plate 9 is located outside the bidirectional screw 8. The outer end of the bidirectional screw 8 passes through the upright plate 9 and is movably connected to the upright plate 9. A nut 10 is provided on the outer side of the upright plate 9 and sleeved on the surface of the bidirectional screw 8. Both ends of the bidirectional screw 8 are provided with grooves 11. The guide rod 12 is fixedly connected to the inner side of the upright plate 9. The side of the guide rod 12 away from the upright plate 9 passes through the transmission plate 3 and the steel structure beam 1. The steel structure beam 1 is fixedly connected to the guide rod 12. The transmission plate 3 and the guide rod 12 are slidably connected. The top and bottom of the steel structure beam 1 are provided with grooves 13. The grooves 13 are located inside the support plate 6.

[0028] Specifically, when the steel curtain wall structure with telescopic mechanism is in operation / use: First, the steel structure beam 1 is moved to the outside of the building, and the groove 13 at the bottom of the steel structure beam 1 needs to be fitted onto the surface of the bottom curtain wall glass. Then, the top curtain wall glass is inserted into the inside of the groove 13 at the top of the steel structure beam 1. When the steel structure beam 1 is installed, the user uses a tool to rotate the double-ended screw 8 through the groove 11. The double-ended screw 8 uses the thread to push the transmission plate 3 to move inward. During the movement of the transmission plate 3, the crank 4 is squeezed, causing the crank 4 to swing from an inclined state to a vertical state. During the swing of the crank 4, the distance between the shaft 5 and the transmission plate 3 is increased, causing the support plate 6 connected to the shaft 5 to move outward. When the support plate 6 passes through the steel structure beam 1 and extends to the outside of the curtain wall glass, the effect of supporting and limiting the curtain wall glass is achieved.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
