The device dismouting is convenient, easy operation construction convenience, and simultaneously, the rubber gasket can effectually play the guard action to the japanning on truss surface when being under construction, can avoid causing the mar to the truss surface at installation and the in-process that slides, is favorable to the protection of truss surface anticorrosive coating.
Description
Technical Field
The utility model belongs to large-span structure construction auxiliary component field especially relates to a long-span truss construction is slided and is supported from auxiliary device that looses.
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.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a can be convenient for the truss assemble accomplish the back and directly slide to reinforcing contact site frictional force reduces the big truss construction of bearing structure steel quantity simultaneously and slides and support from loosing auxiliary device.
The technical scheme of the utility model: the device is by the side semicircle short column that slides, the sideslip side semicircle short column that does not slide, the side short column splice plate that slides, sideslip short column splice plate, the circular arc steel sheet, the bolt, the rubber gasket is constituteed, all leave the bolt hole on the side short column splice plate that slides and the sideslip short column splice plate that does not slide, side short column that slides and sideslip side semicircle short column pass through the side short column splice plate that slides and sideslip short column splice plate, a circular short column is constituteed to bolted connection, the circular arc steel sheet is in order to seal the upper portion opening in circular short column top circular arc incision department welding circular arc steel sheet, fix the rubber gasket on the circular arc steel sheet simultaneously. The circular short column is disassembled after the truss support is completed, the sliding side semi-circular short column can be directly disassembled after the bolt is disassembled, and the truss can directly slide without jacking by using a jack.
Preferably, after the semi-circular short column at the sliding side is detached, the truss can directly slide without being jacked up by a jack, and the non-sliding short column at the sliding side does not influence sliding and can not be detached.
Preferably, the length of the disassembled sliding side short column splice plate is greater than that of the non-disassembled non-sliding side short column splice plate.
Preferably, the auxiliary device 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 the support structure.
The utility model has the advantages that: the circular short column is disassembled after the truss support is completed, the sliding side semi-circular short column can be directly disassembled after the bolt is disassembled, the sliding side 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.
