Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to an assembled steel pipe truss node connection device. Background Technique

[0002] A steel pipe truss refers to a lattice structure composed of circular members connected to each other at the ends. The truss members make the truss structure economical in material use, light in structural self-weight, and easy to form various shapes to adapt to different uses. For example, it can be made into a simply supported truss, arch, frame, tower, etc. When connecting steel pipe trusses, it is necessary to insert the steel pipes into the connection device to connect two steel pipe trusses. Different steel pipe trusses need to be connected through different connection devices.

[0003] However, in the prior art, when connecting trusses with traditional connection devices, the commonly used solution is to fix them with bolts. Therefore, during the process of disassembling and assembling the trusses, construction workers need to frequently tighten the screws to complete the disassembly and assembly, which not only wastes time but also affects the work progress of the staff. In addition, traditional connection devices usually rigidly connect the trusses and cannot reduce the shaking. Therefore, when the bottom truss shakes, the top truss will also shake. When the length of the truss is relatively high, the shaking at the bottom will cause the top truss to shake significantly, thus affecting the construction. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the technical solution adopted by the utility model to solve its technical problems is: an assembled steel pipe truss node connection device, including: a main housing; a sub-housing, the outer wall of the sub-housing is rotatably connected to the outer wall of the main housing through a hinge, and the outer wall of the hinge is fixedly connected to the outer wall of the main housing; a partition, the outer wall of the partition is fixedly connected to the inner wall of the main housing; a limiting mechanism, the outer wall of the limiting mechanism is slidably connected to the inner wall of the sub-housing, and the limiting mechanism is used to limit the position of the truss; a connecting mechanism, the outer wall of the connecting mechanism is fixedly connected to the outer wall of the main housing, and the connecting mechanism is used to connect the truss; the connecting mechanism includes a limiting block, a sliding rod is slidably connected to the inner wall of the limiting block, a plug is fixedly connected to the outer wall of the sliding rod, and the plugs are linearly arranged along the outer wall of the sliding rod. A fixing block is fixedly connected to the outer wall of the sub-housing, a convex block is fixedly connected to the outer wall of the fixing block, and the convex blocks are linearly arranged along the outer wall of the fixing block.

[0005] Preferably, the outer wall of the main housing is fixedly connected to the outer wall of the limiting block, a spring piece is fixedly connected to the inner wall of the limiting block, the material of the spring piece is an elastic material, and the spring pieces are linearly arranged along the outer wall of the limiting block. The outer wall of the spring piece is slidably connected to the outer wall of the plug, the outer wall of the plug is slidably connected to the inner wall of the limiting block, and a reinforcing rib is fixedly connected to the outer wall of the main housing.

[0006] Preferably, the inner wall of the bump is slidably connected to the outer wall of the plug block through a through groove, and the through groove is opened in the wall of the bump. The outer wall of the bump is slidably connected to the inner wall of the limit block through a slot, and the slot is opened in the wall of the limit block. The slots are linearly arrayed along the outer wall of the limit block.

[0007] Preferably, the limiting mechanism includes a limiting frame. An elastic plate is fixedly connected to the outer wall of the limiting frame. The material of the elastic plate is an elastic material, and the elastic plate is slidably connected along the outer wall of the limiting frame. A flexible plate is fixedly connected to the outer wall of the limiting frame. The outer wall of the limiting frame is slidably connected to the inner wall of the main housing. The outer wall of the limiting frame is in contact with the outer wall of the partition plate. A top plate is fixedly connected to the outer wall of the elastic plate.

[0008] The beneficial effects of the present utility model are as follows:

[0009] 1. By setting the connection mechanism in the present utility model, only need to use the main housing and the sub-housing to wrap the truss. After the bump slides into the limit block, the plug block slides into the through groove of the bump, thereby locking the position of the bump. When unlocking is required, only need to slide the sliding rod in the direction away from the limit block to slide the plug block out of the bump, thereby unlocking, achieving the purpose of quickly connecting the truss, and solving the problem that the traditional equipment cannot quickly connect the truss.

[0010] 2. By setting the limiting mechanism in the present utility model, when the elastic plate contacts the truss, under the continuous pressure of the housing, the elastic plate deforms and fits on the truss, and the top plate is used to increase the strength of the elastic plate, thereby restricting the deformation amplitude of the elastic plate, achieving the purpose of reducing the shaking amplitude of the truss, and solving the problem that the traditional equipment cannot reduce the shaking amplitude of the truss.

[0020] The outer wall of the elastic piece 55 is slidably connected to the outer wall of the insertion block 57, the outer wall of the insertion block 57 is slidably connected to the inner wall of the limiting block 53, and the outer wall of the main housing 1 is fixedly connected with a reinforcing rib 7. Reinforcing ribs 7 are fixed on the outer walls of both the main housing 1 and the sub-housing 3, so as to increase the supporting force of the housing through the reinforcing ribs 7. The inner wall of the convex block 52 is slidably connected to the outer wall of the insertion block 57 through a through groove 58, and the through groove 58 is opened in the wall of the convex block 52. The outer wall of the convex block 52 is slidably connected to the inner wall of the limiting block 53 through a slot 54, and the slot 54 is opened in the wall of the limiting block 53.

[0021] The limiting mechanism 4 includes a limiting frame 41. The outer wall of the limiting frame 41 is fixedly connected with an elastic plate 43, and the elastic plate 43 is slidably connected along the outer wall of the limiting frame 41. The outer wall of the limiting frame 41 is fixedly connected with a flexible plate 42. The flexible plate 42 is used to fit on the truss, so as to prevent foreign objects from entering the housing and affecting the connecting device. The outer wall of the limiting frame 41 is slidably connected to the inner wall of the main housing 1, and the outer wall of the limiting frame 41 is in contact with the outer wall of the partition plate 6. The outer wall of the elastic plate 43 is fixedly connected with a top plate 44.

[0022] Working principle:

[0023] When in use, before using the connecting device to connect the steel pipe truss, it is necessary to install the limiting mechanism 4 into the main housing 1 and the sub-housing 3. After installing the four groups of limiting mechanisms 4 on the main housing 1 and the sub-housing 3, then rotate the main housing 1 and the sub-housing 3 along the hinge 2 and wrap them on the truss, so that the truss abuts against the partition plate 6, thereby restricting the position of the truss. After the main housing 1 and the sub-housing 3 are wrapped on the truss, then use the connecting mechanism 5 to lock the positions of the main housing 1 and the sub-housing 3, thereby completing the connection of the truss. Reinforcing ribs 7 are fixed on the outer walls of both the main housing 1 and the sub-housing 3, so as to increase the supporting strength of the housing.

[0024] After the limiting mechanism 4 is installed, the main housing 1 and the sub-housing 3 can be wrapped on the truss. During the process of wrapping the truss, the limiting mechanism 4 contacts the truss first, and the elastic plate 43 on the limiting frame 41 contacts the truss first. And under the continuous pressing of the housing, the elastic plate 43 abuts against the surface of the truss, thereby restricting the position of the truss. The top plate 44 on the elastic plate 43 is used to increase the supporting strength of the elastic plate 43 and reduce the deformation amplitude of the elastic plate 43. And when the truss shakes, the deformation of the elastic plate 43 reduces the shaking amplitude of the truss and increases the stability of the truss. And when it is necessary to connect trusses of different sizes, only the limiting mechanism 4 needs to be replaced, because the flexible plate 42 on the limiting frame 41 fits on the truss, so as to prevent foreign objects from entering the housing.

[0025] After the main housing 1 and the auxiliary housing 3 completely wrap the truss, and the convex block 52 on the fixed block 51 slides into the limiting block 53 along the slot 54, the position of the convex block 52 can be locked, and then the positions of the main housing 1 and the auxiliary housing 3 can be locked. It should be noted that before the convex block 52 slides into the limiting block 53, it is necessary to grasp the handle on the sliding rod 56 and then slide the sliding rod 56 in the direction away from the limiting block 53, so that the insertion block 57 on the sliding rod 56 slides synchronously. During the sliding of the insertion block 57, the elastic piece 55 is squeezed, so that the elastic piece 55 accumulates elastic potential energy.

[0026] When the convex block 52 slides into the limiting block 53, the pulling force on the sliding rod 56 can be released. When the pulling force on the sliding rod 56 disappears, the sliding rod 56 stops squeezing the elastic piece 55, and the elastic piece 55 releases the elastic potential energy, so as to push the insertion block 57 to slide in the direction of the convex block 52, so that the insertion block 57 slides into the convex block 52 along the through groove 58, thereby locking the position of the convex block 52, and then locking the positions of the main housing 1 and the auxiliary housing 3. When it is necessary to unlock the positions of the main housing 1 and the auxiliary housing 3, only need to slide the sliding rod 56 in the direction away from the limiting block 53, and the insertion block 57 can be slid out of the convex block 52, so as to unlock the convex block 52.

Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
