Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a reusable connecting device for a steel frame structure of a tower crane. Background Technology

[0002] With the continuous emergence of high-rise buildings, vertical transportation during structural construction basically relies on tower cranes. Therefore, the use of tower cranes in construction projects is becoming increasingly important. During construction, the connection between the steel structure and the tower crane is the "lifeline" of construction safety. Failure of the connection may lead to accidents, rework, or the dismantling and reconstruction of the tower crane, resulting in huge economic losses.

[0003] In traditional construction, tower cranes and steel structures are mostly connected by welding. However, welding connections require professional welders and strict quality control (such as ultrasonic testing). On-site welding is affected by the weather, and high-temperature welding can easily lead to deformation and residual stress, which may affect fatigue performance. Disassembly or modification of nodes is difficult and maintenance costs are high.

[0004] A standardized, modular connector is needed for simple assembly and installation, eliminating the cumbersome steps of on-site modification of connectors due to errors in early planning or steel component installation, thereby saving a significant amount of installation time.

[0005] Based on this, this utility model designs a reusable connection device under the steel frame structure of a tower crane to solve the problem. Utility Model Content

[0006] The purpose of this utility model is to provide a reusable connection device for a steel frame structure of a tower crane, so as to solve the problems in the background art that cannot be modularized and standardized to reduce assembly and installation, as well as the cumbersome steps required for on-site modification.

Two protrusions are fixedly installed on one side of the two support plates that are close to each other.

[0010] Preferably, the tower crane connection assembly includes two U-shaped connectors disposed between two support plates. Each U-shaped connector has a screw fixedly installed at its right end. The upper surface of the U-shaped connector has two sets of connection holes, and the two second bolts are respectively located inside the two connection holes.

[0011] Preferably, two first blocks are fixedly installed on one side of the two sets of support plates that are close to each other. The left side of each first block is fixedly installed to the outer surface of one of the arc-shaped plates. A second block is fixedly installed on one side of the two support plates that are close to each other. The left side of the second block is fixedly installed to the outer surface of one of the first arc-shaped plates.

[0012] Preferably, two positioning blocks are fixedly installed on the side of each of the two arc-shaped plates that are close to each other, and the side of each of the two sets of positioning blocks that are close to each other is fixedly installed on the side of each of the two sets of mounting plates that are close to each other.

[0013] Preferably, a fixing seat is fixedly installed on the side of each of the two support plates that are far apart from each other, and the left side of each fixing seat is fixedly installed to the right side of one of the arc-shaped plates.

The rubber pad can increase the anti-slip performance and avoid damage to the cylinder during installation. At the same time, by using the combination of a support plate, a U-shaped connector, and a protrusion, the U-shaped connector can be installed with the device to support the tower crane. It can be installed at any part of the cylinder, with flexible installation position, good turnover, easy installation, adjustable connector size, flexible installation position, and low installation cost.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a reusable connection device under a steel frame structure for tower cranes, comprising two arc-shaped plates 1, an installation component 2 on the outside of the two arc-shaped plates 1, a fixing component 3 on the outside of the two arc-shaped plates 1, and a tower crane connection component 4 inside the fixing component 3.

[0024] Please see Figure 1 and Figure 2 Two mounting plates 201 are fixedly installed on the outer surface of each arc plate 1. Each mounting plate 201 has a through hole 205 on its right side. Two sets of first bolts 202 are installed inside the two sets of through holes 205. A first nut 203 is threaded onto the outer surface of each first bolt 202. Rubber pads 206 are fixedly installed on the inner walls of the two arc plates 1. The rubber pads 206 can increase friction and prevent slippage.

[0025] Please see Figure 4The fixing component 3 includes two support plates 301 installed on the outer surface of one of the arc-shaped plates 1.

Each second bolt 302 has a second nut 306 threadedly connected to its outer surface. Two protrusions 304 are fixedly installed on the side of the two support plates 301 that are close to each other. Through the cooperation of the support plates 301 and the protrusions 304, the device can limit the U-shaped connector 401 so that the U-shaped connector 401 can be limited when connected, reducing the time required for the second bolts 302 to be inserted into the connection holes 403.

[0026] Please see Figure 4 The tower crane connection assembly 4 includes two U-shaped connectors 401 disposed between two support plates 301. Each U-shaped connector 401 has a screw 402 fixedly installed at its right end. The upper surface of the U-shaped connector 401 has two sets of connection holes 403. Two second bolts 302 are located inside the two connection holes 403 respectively. The U-shaped connectors 401 can be connected to the tower crane.
