Description

Technical Field

[0001] This utility model relates to the field of hoisting construction technology, specifically a hoisting construction device for large-span steel structure steel space frame. Background Technology

[0002] Steel space frame is a spatial grid structure composed of multiple members connected by a certain node connection method. It has the advantages of spatial stress, light weight, high rigidity, good seismic performance and fast construction speed. Therefore, it is widely used in large-span buildings such as stadiums, exhibition halls, airports and warehouses.

[0003] Steel space frame structures require hoisting during construction. After welding and installation on the ground, the steel space frame is lifted and installed above the building. Traditional hoisting methods typically involve using cranes with multiple steel cables for securing the structure. However, traditional cable fixing often relies on multiple bolts for single-layer steel space frame support, primarily fixing to the upper members without adequate anti-falling mechanisms. During large-span hoisting, if one connection point breaks or loses its fixation, the steel space frame's own weight can cause other connection points to break, leading to the steel space frame falling and breaking, posing a safety hazard. Furthermore, disassembling the steel cables after hoisting is cumbersome. Therefore, we propose a large-span steel space frame hoisting device to address these issues. Utility Model Content

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.

[0023] Example: Figure 1-4As shown, this utility model provides a large-span steel structure steel grid hoisting construction device, including a fixing component 1, an installation component 2 on the fixing component 1, an anti-fall component 3 at the bottom of the installation component 2, a connecting component 5 between the installation component 2 and the anti-fall component 3, and a connecting ring 4 at the top of the fixing component 1.

The mounting loop 2211 is fixedly mounted at the bottom end of the first rope 21. An mounting hook 222 for hanging on the outside of a member in a steel grid frame is integrally formed at the bottom end of the mounting rod 221. An anti-slip pad 2221 is provided on the inner side of the mounting hook 222 to increase the mounting hook's position. The anti-slip effect of installation 222; the end of the installation hook 222 away from the installation vertical rod 221 has an integrally formed rotating frame 223, in which a rotating block 224 is movably engaged; a rotating shaft 2241 is fixedly installed in the middle of the rotating block 224, and the rotating shaft 2241 is rotatably installed in the middle of the rotating frame 223; a limiting diagonal rod 225 is integrally formed on the outer side of the rotating block 224, and a limiting bolt 226 is integrally formed on the top of the limiting diagonal rod 225; the top of the installation vertical rod 221 has an opening. The limiting slot 201 corresponds to the limiting bolt 226. The end of the limiting bolt 226 away from the limiting inclined rod 225 passes through the limiting slot 201 and is threaded with a limiting nut 2261. One end of the rotating shaft 2241 is fixedly installed with a torque handle 2242. During installation, the first mounting part 22 in the mounting assembly 2 is placed on the outside of the upper part of the rod in the steel grid frame through the mounting hook 222, and the limiting inclined rod 225 is rotated so that the end of the limiting bolt 226 away from the limiting inclined rod 225 passes through the limiting slot 201. The groove 201 is threaded with a limit nut 2261 to fix the limit bolt 226 and the limit rod 225. The steel grid frame is limited by the limit bolt 226, the limit rod 225 and the installation hook 222. When disassembling, only one limit nut 2261 needs to be removed. The limit rod 225 is manually rotated by the torque handle 2242 to control the limit bolt 226 to rotate in the opposite direction, so that the limit bolt 226 is disengaged from the limit groove 201. Then, the installation hook 222 can be quickly removed from the rod.

[0025] The anti-fall component 3 includes a second rope 31, and a second mounting piece 32 is fixedly installed at the bottom end of the second rope 31; the connector 5 includes a first connecting frame 51 and a second connecting frame 52, and connecting slots corresponding to the first rope 21 and the second rope 31 are opened on opposite sides of the first connecting frame 51 and the second connecting frame 52. The bottom of the first rope 21 and the top of the second rope 31 are movably engaged in the connecting slots. A connecting bolt 53 is threaded between the first connecting frame 51 and the second connecting frame 52 to connect and fix the anti-fall component 3 and the first rope 21.

[0026] The structure of the second mounting component 32 is the same as that of the first mounting component 22. In use, the second mounting component 32 in the anti-fall component 3 is installed on the outside of the rod at the lower position of the steel space frame to assist in the installation and fixation of the lower part of the steel space frame, thereby increasing the anti-fall function of the steel space frame installation. When the first mounting component 22 in the mounting component 2 is detached from the steel space frame, the second mounting component 32 in the anti-fall component 3 can continue to connect to the steel space frame, thereby improving the safety of large-span hoisting after the steel space frame is installed.

[0027] The fastener 1 includes a fixed inner frame 11 and a fixed outer frame 12 on the outside of the fixed inner frame 11. A fixed through groove 101 corresponding to the first rope 21 is opened between the fixed inner frame 11 and the fixed outer frame 12. The installation component 2 is movably snapped into the corresponding fixed through groove 101 by the first rope 21. A fixing bolt 13 is threaded between the fixed inner frame 11 and the fixed outer frame 12 to connect and fix multiple installation components 2. The first rope 21 of appropriate length can be installed according to the span of multiple connection positions of the steel grid frame for use.

[0028] A connecting bracket 41 is fixedly installed at the bottom of the connecting ring 4, and the bottom of the connecting bracket 41 is welded to the top of the fixed inner frame 11.

[0029] Working principle: When in use, the entire construction device is installed on the lifting end of the crane via the connecting ring 4. First, according to the span of the multiple connection positions of the steel grid, the first rope 21 of appropriate length is installed for use.

[0030] Subsequently, the first mounting component 22 in the mounting assembly 2 is fitted onto the outside of the upper part of the rod in the steel space frame through the mounting hook 222, and the limiting diagonal bar 225 is rotated so that the end of the limiting bolt 226 away from the limiting diagonal bar 225 passes through the limiting through slot 201, and the limiting nut 2261 is threaded on to fix the limiting bolt 226 and the limiting diagonal bar 225. The steel space frame is limited and installed through the limiting bolt 226, the limiting diagonal bar 225 and the mounting hook 222.

[0031] Subsequently, the second mounting component 32 in the anti-fall component 3 is installed on the outside of the rod at the lower position of the steel space frame to assist in the installation and fixation of the lower part of the steel space frame, thereby increasing the anti-fall function of the steel space frame installation. When the first mounting component 22 in the mounting component 2 is detached from the steel space frame, the second mounting component 32 in the anti-fall component 3 can continue to connect to the steel space frame, thereby improving the safety of large-span hoisting after the steel space frame is installed.

[0032] Subsequently, the crane was used to drive the lifting and lowering of the entire construction device and the large-span hoisting and transportation.

[0033] After transportation, simply remove one of the limiting nuts 2261 from the first mounting component 22 and the second mounting component 32, manually rotate the torque handle 2242 to control the limiting inclined rod 225 to rotate in the opposite direction, so that the limiting bolt 226 disengages from the limiting through groove 201, and then the mounting hook 222 can be quickly removed from the rod.
