Description

Technical Field

[0001] This utility model relates to the field of building structure engineering technology, specifically a transition device for connecting modular self-balancing ETFE membrane structures to steel structures. Background Technology

[0002] As is well known, ETFE membrane structures are a lightweight and tough high-grade material composed of ethylene-tetrafluoroethylene copolymer (ETFE) membrane material and steel structure. It has advantages such as high transparency, light weight, high strength and long service life. ETFE membrane structures are widely used in the construction field, and can provide the advantages of low-cost construction, flexible design and environmental protection and energy saving.

[0003] The adapter for connecting ETFE membrane structures to steel structures is a device that connects and fixes the ETFE membrane structure to the steel structure. However, the clamps on the existing adapters are mostly fixed installations, so they cannot be adapted to different specifications of ETFE membrane structures. When it is necessary to fix ETFE membrane structures of different specifications, it is necessary to replace the entire adapter that is adapted to the ETFE membrane structure, which increases the cost of ETFE membrane structure installation and reduces installation efficiency. Utility Model Content

[0004] Technical problems to be solved

[0005] To overcome the problem that existing adapters for connecting modular self-balancing ETFE membrane structures to steel structures cannot replace the clamps, this invention provides an adapter for connecting modular self-balancing ETFE membrane structures to steel structures that allows for convenient clamp replacement.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a transition device for connecting a modular self-balancing ETFE membrane structure to a steel structure, comprising a body, the interior of which is provided with a groove and two sets of movable slots for connecting a connecting frame to the steel structure. The connecting frame is disposed on one side of the body and installed on the outside of the steel structure. An installation assembly is disposed within the movable slots for installing clamps. The installation assembly includes a horizontal plate slidably disposed within the movable slots and two sets of support plates. Two sets of limiting rods are provided on one side of the horizontal plate for limiting rods to... The support plate is secured so that it cannot slide outside the limiting rod and detach from the machine body. A mounting plate is provided on the side of the horizontal plate away from the limiting rod. A protrusion, which is semi-elliptical, is provided on the side of the mounting plate away from the horizontal plate. The support plate has mounting holes that are parallel to the limiting rod inside. One side of the support plate penetrates the machine body and has two sets of connecting columns on one side. The connecting columns are located on the outside of the machine body. One end of each of the four sets of connecting columns is fixed to a clamping plate. The clamping plate is used to fix the ETFE membrane structure and the first drive assembly located inside the machine body.

[0008] Preferably, a movable plate is slidably provided on the outer side of the limiting rod, and a spring is provided on the side of the movable plate away from the support plate. The end of the spring away from the movable plate is fixedly provided to the cross plate.

[0009] Furthermore, the bump is inclined and is a semi-elliptical bump.

[0010] Furthermore, the first drive assembly includes a first bearing disposed within the machine body, a first threaded tube disposed in the middle of the first bearing, a first sleeve screwed onto the outer side of the first threaded tube, and two sets of push rods disposed on the outer side of the first sleeve, with the outer side of the push rods contacting the outer side of the protrusions.

[0011] In a further embodiment, the end of the first threaded tube away from the first bearing passes through the machine body, and a first handle is provided at the end of the first threaded tube away from the first bearing. The first handle is used to facilitate the rotation of the first threaded tube.

[0012] Based on the aforementioned scheme, the clamping plate is slidably disposed on the outside of the machine body, and an anti-slip pad is provided on the side of the clamping plate away from the connecting column. The anti-slip pad can prevent the ETFE membrane structure from detaching from the clamping plate.

[0013] Furthermore, based on the aforementioned solution, a second driving assembly is provided on the inner wall of the groove. The second driving assembly is located on the side of the support plate away from the limiting rod and is used to drive the clamping plate.

[0014] Furthermore, based on the aforementioned scheme, the second drive assembly includes a second bearing disposed on the inner wall of the groove, a second threaded tube disposed in the middle of the second bearing, a second sleeve screwed onto the outer side of the second threaded tube, a push plate disposed on the outer side of the second sleeve, and the push plate being located on the side of the support plate away from the limiting rod.

[0015] Beneficial effects

[0016] This adapter for connecting modular self-balancing ETFE membrane structures to steel structures uses a limiting rod and a support plate to work together. After the limiting rod is engaged in the mounting hole, the support plate is stably installed inside the machine body.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] See Figures 1-7 A transfer device for connecting a modular self-balancing ETFE membrane structure to a steel structure includes a body 1 for installing the ETFE membrane structure. Two sets of clamping plates 6 are slidably connected inside the body 1. A connecting frame 5 is bolted to the bottom of the body 1 for connecting the steel structure. The body 1 has a groove 9 and two sets of movable slots 7 inside. An installation component 2 is slidably connected inside the movable slots 7, and one side of the installation component 2 passes through the body 1 and is bolted to the clamping plate 6. A first drive component 3 is provided inside the body 1, and a second drive component 4 is provided on the inner wall of the groove 9.

[0027] First, refer to Figures 1 to 4 In this embodiment, the mounting assembly 2 includes a horizontal plate 201 slidably disposed in the movable groove 7 and two sets of support plates 207. Two sets of limiting rods 205 are welded to the top of the horizontal plate 201. A mounting plate 204 is welded to the side of the horizontal plate 201 away from the limiting rods 205. A protrusion 202 is welded to the side of the mounting plate 204 away from the horizontal plate 201. The protrusion 202 is inclined and is a semi-elliptical protrusion. The support plate 207 has mounting holes 209 arranged parallel to the limiting rods 205 inside. One side of the support plate 207 penetrates the body 1, and two sets of connecting columns 206 are bolted to the bottom of the support plate 207. The bottom ends of the four sets of connecting columns 206 are all bolted to the clamping plate 6. An anti-slip pad 8 is provided on the side of the clamping plate 6 away from the connecting columns 206.

[0028] Then, refer to Figures 2 to 4 In this embodiment, a movable plate 203 is slidably disposed on the outer side of the limiting rod 205. A spring 208 is disposed on the side of the movable plate 203 away from the support plate 207. The end of the spring 208 away from the movable plate 203 is fixedly disposed with the horizontal plate 201. Thus, when the support plate 207 moves down, it will push the movable plate 203. At this time, the movable plate 203 will squeeze the spring 208. When the support plate 207 stops pushing the movable plate 203, the spring 208 will drive the support plate 207 to move back by bouncing the movable plate 203 back, so that the support plate 207 can quickly return to the initial position and ensure the reuse of the device.

[0029] After the support plate 207 is inserted into the movable groove 7, the mounting hole 209 will be located above the limit rod 205. When the protrusion 202 is pushed, the protrusion 202 will drive the mounting plate 204 to move. The movement of the mounting plate 204 will drive the limit rod 205 to move, so that the limit rod 205 moves into the mounting hole 209. At this time, the support plate 207 will be fixed in the machine body 1, and the installation of the fixture will be completed.

[0030] Secondly, see Figure 1 , Figure 2 and 5 In this embodiment, the first drive assembly 3 includes a first bearing 305 disposed in the body 1. A first threaded tube 304 is disposed in the middle of the first bearing 305. A first sleeve 303 is screwed onto the outer side of the first threaded tube 304. When the first threaded tube 304 rotates, it will drive the first sleeve 303 screwed onto its outer side to move linearly. The operator can control the movement direction of the first sleeve 303 by controlling the rotation direction of the first threaded tube 304. Two sets of top rollers 302 are disposed on the outer side of the first sleeve 303, and the outer side of the top rollers 302 contacts the outer side of the protrusion 202.

[0031] Again, see Figure 1 , Figure 2 and 5 In this embodiment, the end of the first threaded tube 304 away from the first bearing 305 passes through the machine body 1, and the end of the first threaded tube 304 away from the first bearing 305 is provided with a first handle 301, so that the operator can conveniently rotate the first threaded tube 304 through the first handle 301.

[0032] When the first handle 301 is turned, the first handle 301 will drive the first threaded tube 304 to rotate. The rotation of the first threaded tube 304 will drive the first sleeve 303 to move linearly. When the first sleeve 303 moves, it will drive the top rod 302 to move, so that the top rod 302 pushes the protrusion 202 to move upward during the movement.

[0033] In addition, see Figure 1 , Figure 6 and Figure 7 In this embodiment, the second drive assembly 4 includes a second bearing 405 disposed on the inner wall of the groove 9. A second threaded tube 404 is disposed in the middle of the second bearing 405. A second sleeve 403 is screwed onto the outer side of the second threaded tube 404. When the second threaded tube 404 rotates, it will drive the second sleeve 403 screwed onto its outer side to move linearly. The operator can control the movement direction of the second sleeve 403 by controlling the rotation direction of the second threaded tube 404. A push plate 406 is disposed on the outer side of the second sleeve 403. The push plate 406 is located on the side of the support plate 207 away from the limit rod 205. At the same time, the push plate 406 will not block the mounting hole 209.

[0034] Finally, see Figure 1 , Figure 6 and Figure 7 In this embodiment, a rotating column 402 is welded to the top of the second threaded tube 404. The top of the rotating column 402 passes through the machine body 1 and is fastened to the second handle 401. Thus, the operator can rotate the second threaded tube 404 by rotating the second handle 401.

[0035] After the clamping plate 6 is installed, turn the second handle 401 to make the second threaded tube 404 rotate. The rotation of the second threaded tube 404 will cause the second sleeve 403 to move linearly. The movement of the second sleeve 403 will cause the push plate 406 to move. At this time, the push plate 406 will push the four sets of support plates 207. When the support plates 207 move, they will cause the connecting column 206 to move. The movement of the connecting column 206 will cause the clamping plate 6 to move, so that the clamping plate 6 will fix the ETFE membrane structure in the body 1 after it moves, thus completing the connection between the ETFE membrane structure and the steel structure.

[0036] This adapter for connecting modular self-balancing ETFE membrane structures to steel structures uses a limiting rod 205 and a support plate 207 to work together. After the limiting rod 205 is engaged in the mounting hole 209, the support plate 207 will be stably installed inside the body 1. The fixing of the support plate 207 will stably install the clamping plate 6 inside the device. After the limiting rod 205 is disengaged from the mounting hole 209, the clamping plate 6 can be disassembled, allowing operators to quickly replace the clamping plate 6. This makes the device adaptable to fixing different ETFE membrane structures, increasing the range of applications of the device.

[0037] Working principle:

[0038] The adapter for connecting a modular self-balancing ETFE membrane structure to a steel structure is used by first placing it in the desired position, then mounting the connecting frame 5 onto the steel structure. Next, the clamping plate 6 is installed. Specifically, the support plate 207 is inserted into the movable groove 7, with the mounting hole 209 positioned above the limiting rod 205. Then, the first handle 301 is turned to rotate the first threaded tube 304. This rotation causes the first sleeve 303 to move linearly, which in turn causes the top roller 302 to move, pushing the protrusion 202 upwards. When the protrusion 202 is pushed, it causes the mounting plate 204 to move, which in turn causes the limiting rod 205 to move into the mounting hole 209. At this point, the support plate 207 is secured within the body 1, completing the installation of the clamp.

[0039] Secondly, the ETFE membrane structure is fixed. The specific operation is as follows: place the ETFE membrane structure under the clamping plate 6, and then turn the second handle 401 to make it rotate the second threaded tube 404. The rotation of the second threaded tube 404 will cause the second sleeve 403 to move linearly. The movement of the second sleeve 403 will cause the push plate 406 to move. At this time, the push plate 406 will push the four sets of support plates 207. When the support plates 207 move, they will cause the connecting column 206 to move. The movement of the connecting column 206 will cause the clamping plate 6 to move, so that the clamping plate 6 fixes the ETFE membrane structure in the body 1 after it moves, thus completing the connection between the ETFE membrane structure and the steel structure.

[0040] Finally, when replacing the clamping plate 6 of different specifications, the specific operation is as follows: reverse the first handle 301 to move the first sleeve 303 back. At this time, the top rod 302 no longer pushes the protrusion 202. Then the spring 208 will bounce the horizontal plate 201 back. The back movement of the horizontal plate 201 will drive the limit rod 205 back to no longer be located in the mounting hole 209. At this time, the support plate 207 is no longer fixed. The operator can then disassemble the support plate 207 and the clamping plate 6 to replace the clamping plate 6.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
