Description

Technical Field

[0001] The utility model belongs to the technical field of connecting components of a steel cable type earthquake-resistant support, and more specifically, particularly relates to a connecting component of a steel cable type earthquake-resistant support. Background Art

[0002] In recent years, with the improvement of people's safety awareness, the country has attached more and more importance to earthquake disaster reduction work, and has issued a series of mandatory standards and specifications for earthquake-resistant support and hanger equipment. Before 2008, the application of projects in related fields in China basically had no concept of electromechanical engineering earthquake resistance. After the Wenchuan earthquake, the Ministry of Construction revised the original "Building Seismic Design Code" many times, and officially promulgated the "Building Electromechanical Engineering Seismic Design Code" as a national standard in 2014, which was enforced on August 1, 2015. This national standard comprehensively explains the basic design requirements of earthquake-resistant measures. The purpose is to enable the electromechanical engineering facilities such as water supply and drainage, heating, ventilation, air conditioning, gas, heat, electricity, communication, fire protection, etc. of buildings to reduce earthquake damage, prevent secondary disasters, avoid casualties, and reduce economic losses after earthquake-resistant fortification. It is required to be safe and reliable, technologically advanced, economically reasonable, and easy to maintain and manage. Among them, earthquake-resistant supports and hangers are widely used in the installation of engineering construction.

[0003] Existing seismic supports are used to limit the displacement of attached electromechanical engineering facilities, control the vibration of the facilities, and transfer the load to various components or devices on the bearing structure. They are mostly used in pipeline integrated corridors to protect water pipes, bridges, wiring racks, air ducts, gas pipelines, data rooms, etc.

[0004] The existing earthquake-resistant bracket generally includes a crossbeam, on which the equipment to be fixed (such as water pipes or air ducts, etc.) is fixed by C-shaped steel, and both ends of the crossbeam are fixed to the ceiling by vertical hangers. When encountering an earthquake, it can reduce earthquake damage, reduce and prevent the damage of water pipes, bridges, wiring racks, air ducts, and gas pipelines as much as possible, causing the recurrence of disasters, thereby achieving the purpose of reducing casualties and property losses. The existing earthquake-resistant bracket is connected by a vertical hanger such a connecting component, which has a poor earthquake-resistant effect. At the same time, it is used in the earthquake-resistant bracket structure. The existing ones are generally based on C-shaped steel. With the improvement of earthquake-resistant requirements, many old computer rooms are facing the problem of not meeting earthquake-resistant requirements. At present, manufacturers produce them in specified sizes and then send them to the installation site for installation. This method cannot be installed if there is an abnormality at the installation site, and a large number of old computer rooms have already installed bridges, wiring racks and other equipment. If the earthquake-resistant bracket needs to be reinstalled, the existing C-shaped steel specifications need to be customized according to different on-site environments, which makes the manufacturer's production more troublesome. Among them, Chinese patent application number: CN202121563056.X discloses a connecting member of a steel cable type seismic support and a seismic support hanging structure, including a mounting seat for fixing to a ceiling, a connecting piece for traction and seismic resistance is provided on the mounting seat, and a fixing seat is connected to the connecting piece. It includes a crossbeam, a fixing device to be fixed is provided on the crossbeam, the fixing device is fixed to the crossbeam through a fixing piece, both ends of the crossbeam are fixed to the ceiling through a vertical hanger, and at least one of the above-mentioned connecting members of the steel cable type seismic support is provided at the place where the vertical hanger and the crossbeam are connected, and the other end of the connecting member of the steel cable type seismic support is fixed to the ceiling. The utility model has a reasonable design and is easy to install. It has a better seismic effect than ordinary C-shaped steel, and it can be cut at any time at the installation site, which reduces the construction difficulty and can better meet the use requirements.

[0005] Based on the above, the inventors found that there are the following problems:

[0006] The connecting components of the above-mentioned steel cable type seismic support have better seismic resistance than ordinary C-shaped steel, and they can be cut at any time at the installation site, reducing the difficulty of construction. However, the steel cable will undergo structural elongation over time, affecting the seismic resistance of the seismic support. Therefore, it is necessary to regularly adjust its tension and damage.

[0007] Therefore, in view of this, the existing structure and defects are studied and improved, and a connecting component of a steel cable type seismic support is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0037] Specific usage method and function of this embodiment:

[0038] When using this device, first check the integrity of the device. When the steel cable 1 in this steel cable type seismic support needs to be tightened and adjusted, first move the U-shaped plate 415 to an angle perpendicular to the mechanism main body 401, and then drive the second clamping member 411 to rotate in the I-shaped groove 402 by moving the twisting block 407, thereby driving the threaded rod 408 to rotate in the thread groove 413, and further shortening the distance between the threaded sleeve 412 and the mechanism main body 401. Because both ends of the tensioning mechanism 4 are connected with the mounting seat 2 and the steel cable 1 through the connecting component 6, the distance between the mounting seat 2 and the steel cable 1 is indirectly shortened, thereby realizing the tightening adjustment of the steel cable 1. When adjusted to the appropriate degree, prevent the threaded rod 408 from rotating in the thread groove 413, release the U-shaped plate 415, and make it restore the form of clamping the twisting block 407 under the action of the torsion spring 416. Among them, the rolling movement of the sphere 406 in the first annular groove 404 and the second annular groove 405 makes the movement of the second clamping member 411 smoother. Through the shape design of the first clamping member 410 and the I-shaped groove 402, when the threaded rod 408 rotates, it will not drive the mechanism main body 401 to rotate, avoiding affecting the connection effect between the mounting seat 2 and the connecting component 6; when the steel cable 1 or the tensioning mechanism 4 needs to be replaced, move the handle 605 in the sliding hole 606 to realize the opening and closing effect of the engaging member 601 and the engaging sleeve 602 away from one end of the rectangular groove 603, so that the steel cable 1 and the tensioning mechanism 4 can be easily replaced, saving manpower.
