Description

Technical Field

[0001] This invention relates to a steel structure space frame. Background Technology

[0002] With the continuous development of society, construction methods are constantly changing, and the performance requirements for materials are becoming increasingly stringent. In construction engineering, the structural quality of steel directly determines the stability and solidity of a building. One of the most commonly used structures in construction today is the space frame structure. In complex engineering projects, the construction of space frame structures has become quite mature in my country. However, various construction defects are still inevitable during the process.

[0003] Specifically, when constructing existing steel structure space frames in open areas, it is necessary to first install multiple support rods on the ground, and then use these support rods to support the steel structure space frame in the air until the entire steel structure space frame is completed. Only then are the support rods on the ground removed. During this construction process, there are significant inconveniences in connecting, fixing, and dismantling the support rods and the steel structure space frame while working at height. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a steel structure space frame that is easy to connect and fix to ground support poles and to dismantle in high-altitude working environments.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A steel structure space frame includes space frame rods arranged in a crisscross pattern, and support rod connectors installed on the space frame rods. Each support rod connector includes a clamping head that clamps and fixes the space frame rod, a clamping arm that is rotatably connected to the clamping head, a clamping seat that is rotatably connected to the clamping arm, and a support rod connecting seat that is fixedly connected to the clamping seat. The support rod connecting seat has a support rod through hole and a support rod fixing hole surrounding the support rod through hole.

[0007] Preferably, the clamping head includes a clamping body that clamps the space frame rod from the top and bottom, a bolt that passes through the clamping body in the vertical direction and abuts against the space frame rod, and a clamping body seat that is rotatably connected to the clamping body, wherein the bolt and the clamping body are threaded together.

[0008] Preferably, the bolt is provided with an abutment at its end. The abutment is a round handle block with anti-slip texture. The abutment and the bolt are integrally formed and connected. The end of the abutment with anti-slip texture abuts against the space frame pole.

[0009] Preferably, the clamping arm includes an arm body that is hinged to the rear end of the clamping seat, and a cylinder component with one end hinged to the arm body and the other end hinged to the clamping seat, wherein the rod end of the cylinder component is connected to the arm body.

[0010] Preferably, there is a height difference between the hinge position between the arm body and the clamping seat and the hinge position between the cylinder and the arm body.

[0011] Preferably, the hinge structure formed between the arm body and the clamping seat, the clamping seat and the cylinder component, and the cylinder component and the arm body rotates in the same direction.

[0012] Preferably, the horizontal position of the hinge between the cylinder and the clamping seat is located between the hinge position between the arm and the clamping seat and the hinge position between the cylinder and the arm.

[0013] Preferably, the clamping seat includes a seat body that is hinged to the clamping arm, and a connecting block that passes through the support rod connecting seat and is fixedly connected to the seat body.

[0014] Preferably, the clamping head and the space frame rod form a lateral rotatable connection, the clamping arm and the clamping head form a vertical rotatable connection, and the clamping seat and the clamping head form a vertical rotatable connection.

[0015] Preferably, each support rod connector is equipped with one or more sets of clamping heads, clamping arms and clamping seats, and at least one set of clamping heads, clamping arms and clamping seats is in a clamping direction opposite to that of the other sets of clamping heads, clamping arms and clamping seats.

[0016] The beneficial effects of this invention are:

[0017] The high-altitude connection, installation, and dismantling of the support rods and steel structure space frame is achieved by using a combination of space frame poles and support rod connectors. First, the support rod connectors are clamped using clamping heads, and the lateral clamping direction is adjusted. Then, the vertical clamping angle of the clamping heads is adjusted using clamping arms. Finally, the distance between the clamping arms and the support rods is adjusted using clamping seats. This facilitates the connection, installation, and dismantling of the support rods and space frame poles in high-altitude environments. Attached Figure Description

[0025] Example

[0026] See Figure 1-4As shown, a steel structure space frame includes space frame rods 1 arranged in a crisscross pattern, and support rod connectors 2 installed on the space frame rods 1. The support rod connectors 2 include clamping heads 21 that clamp and fix the space frame rods 1, clamping arms 22 that are rotatably connected to the clamping heads 21, clamping seats 23 that are rotatably connected to the clamping arms 22, and support rod connecting seats 24 that are fixedly connected to the clamping seats 23. The support rod connecting seats 24 have support rod through holes 25 and support rod fixing holes 26 surrounding the support rod through holes 25.

[0027] The clamping head 21 includes a clamping body 211 that clamps the space frame rod 1 from top to bottom, a bolt 212 that passes through the clamping body 211 in the vertical direction and abuts against the space frame rod 1, and a clamping body seat 213 that is rotatably connected to the clamping body 211. The bolt 212 and the clamping body 211 are threaded together.

[0028] The clamp 211 is set in a semi-I-shape and its size is larger than the thickness of the space frame pole 1, so as to clamp the space frame pole 1 from the side. In conjunction with the bolt 212 that passes through the clamp 211, it abuts against the clamp 211 from the bottom to form a clamping and fixing. Considering the mobility of the support rod connector 2, the clamp 211 is designed to be able to rotate laterally, so as to facilitate the adjustment of the clamping position and direction of the clamp 211 on the space frame pole 1 and improve its applicability.

[0029] The bolt 212 has an abutment 214 at its end. The abutment 214 is a round handle block with anti-slip texture. The abutment 214 and the bolt 212 are integrally formed. The end of the abutment 214 with anti-slip texture abuts against the space frame rod 1. The abutment 214 is driven by the bolt 212. The tightening of the bolt 212 clamps and fixes the space frame rod 1, and the anti-slip texture improves its fixing effect.

[0030] The clamping arm 22 includes an arm body 221 that is hinged to the rear end of the clamping seat 213, and a cylinder 222 that is hinged at one end to the arm body 221 and at the other end to the clamping seat 213. The rod end of the cylinder 222 is connected to the arm body 221. There is a height difference between the hinge position between the arm body 221 and the clamping seat 23 and the hinge position between the cylinder 222 and the arm body 221. The hinge structure formed between the arm body 221 and the clamping seat 23, the clamping seat 23 and the cylinder 222, and the cylinder 222 and the arm body 221 rotates in the same direction. The horizontal position of the hinge between the cylinder 222 and the clamping seat 23 is between the hinge position between the arm body 221 and the clamping seat 23 and the hinge position between the cylinder 222 and the arm body 221.

[0031] The clamping seat 23 includes a seat body 231 that is hinged to the clamping arm 22, and a connecting block 232 that passes through the support rod connecting seat 24 and is fixedly connected to the seat body 231. The clamping head 21 is rotatably connected to the grid rod 1, the clamping arm 22 is rotatably connected to the clamping head 21, and the clamping seat 23 is rotatably connected to the clamping head 21.

[0032] Each support rod connector 24 is equipped with one or more clamping heads 21, clamping arms 22 and clamping seats 23, and at least one set of clamping heads 21, clamping arms 22 and clamping seats 23 is in a clamping direction opposite to that of other sets of clamping heads 21, clamping arms 22 and clamping seats 23.

[0033] When installing a steel structure space frame in an open area, firstly, multiple support rods are laid on the open ground. Then, based on the laying position of the support rods, support rod connectors 2 are installed at the corresponding positions of the space frame rods 1. The clamps 211 are used to clamp the space frame rods 1, so that the support rod connectors 24 are roughly positioned above the support rods. Next, the position of the support rod connectors 24 is finely adjusted using the clamping heads 21, clamping arms 22, and clamping seats 23 until the support rod through holes 25 and support rods are properly aligned. Finally, the support rods are fixed to the support rods through the support rod fixing holes 26. Depending on the number and position of the support rods, multiple support rod connectors 2 can be installed for installation.

[0034] The beneficial effects of this invention are:

[0035] The high-altitude connection, installation, and dismantling of the support rods and steel structure space frame is achieved by using a combination of space frame poles and support rod connectors. First, the support rod connectors are clamped using clamping heads, and the lateral clamping direction is adjusted. Then, the vertical clamping angle of the clamping heads is adjusted using clamping arms. Finally, the distance between the clamping arms and the support rods is adjusted using clamping seats. This facilitates the connection, installation, and dismantling of the support rods and space frame poles in high-altitude environments.

[0036] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention. The implementation of the present invention is not limited thereto. All other modifications, substitutions or alterations made to the above structure of the present invention based on the above content of the present invention, in accordance with ordinary technical knowledge and common practice in the field, without departing from the basic technical idea of ​​the present invention, shall fall within the scope of protection of the present invention.
