Description
Technical Field
The invention belongs to the field of large-span structure construction auxiliary components, and particularly relates to a sliding support self-dispersion auxiliary device for large-span truss construction.
Background
In the construction process of the large-span complex steel structure, although the steel truss has the characteristic of high strength, buckling is easy to occur if the steel truss does not have the effect of a supporting structure in the assembling process. In order to ensure the structural integrity of the truss, the truss must be supported temporarily and permanently in the assembling and positioning process and after positioning, and the temporary support has the function of ensuring that the truss can bear the dead weight, wind load during construction and other temporary construction loads. With the progress of the technology, patent CN208310248U proposes an adjustable assembling jig, which can adjust the supporting height to adapt to trusses of different shapes and sizes, but does not consider the influence of the direct contact with the trusses when the steel pipe short column is supported on the assembling process.
The traditional mode of large-span truss construction is that the contact part of the assembled jig frame column top and the truss adopts a steel pipe short column to directly contact with the lower chord of the truss, the steel pipe short column is an arc-shaped notch, and the lower chord of the truss is directly placed on the steel pipe short column. In the process of assembling the truss, although the traditional steel pipe short column can support the truss, the truss can slide after being assembled by using a jack, and a space is reserved for placing the jack before the truss is assembled, so that time and labor are wasted, and the construction cost is increased.
Disclosure of Invention
The invention aims to provide a large-span truss construction sliding support self-dispersing auxiliary device which can facilitate direct sliding of a truss after assembly, enhance the friction force of a contact part and reduce the steel consumption of a support structure.
The technical scheme of the invention is as follows: the device is by two semicircle short columns, short column splice plate, the circular arc steel sheet, the bolt, the rubber gasket is constituteed, two semicircle short columns pass through short column splice plate, a round short column of bolted connection constitution, dismantle after the truss support is accomplished to the round short column, can directly unload a semicircle short column of slip direction one side after demolising the bolt, the truss does not use jack jacking alright directly slide, the top of round short column is the circular arc steel sheet, pass through welded connection between circular arc steel sheet and the round short column, circular arc steel sheet top is fixed with the rubber gasket.
Preferably, after the semi-circular short column on one side of the sliding direction is detached, the truss can directly slide without being jacked up by a jack, and the short column on the other side does not influence sliding and can not be detached.
Preferably, the length of the stub splice plate of the disassembled part is greater than that of the stub splice plate of the non-disassembled part.
Preferably, the apparatus is capable of reducing the calculated length of the support structure and improving its stability, while reducing the amount of steel used for the columns and support structure.
The invention has the beneficial effects that: the round short column is disassembled after the truss support is completed, a semi-circular short column on one side of the sliding direction can be directly disassembled after the bolt is disassembled, after the semi-circular short column is disassembled, the truss can be directly slid without being jacked by a jack, the operation is simple, the construction is convenient, meanwhile, the rubber gasket can effectively play a role in protecting the painting on the surface of the truss during construction, scratches and extrusion damage to the surface of the truss can be avoided in the installation and sliding processes, and the protection of an anticorrosive coating on the surface of the truss is facilitated.
