Description
Technical Field
The utility model relates to an installation and interim the fixing of large-span steel construction, specific interim bearing structure of steel construction that says so.
Background
In recent years, with the development of steel structures, particularly large-span steel structures, overhanging steel structures and various deformed steel structures are used more and more, and the installation of the large-span steel structures, the overhanging steel structures and the like are always prone to integral hoisting or local segmented hoisting, so that the risk of high-altitude bulk loading can be effectively reduced, and the influence of high-altitude welding on quality can be reduced. However, before a structure stabilizing system is formed, the steel structure needs to be provided with a temporary support to ensure that the stability of the structure meets the requirements, so that the installation, adjustment and turnover of the temporary support become a construction difficulty for the installation of the steel structure. At present large-scale steel construction integral hoisting adopts the groined type frame to support temporarily more, but the weight of groined type frame is big, and the hoist and mount turnover is troublesome and laboursome, and constructor need climb to the height adjustment that supports temporarily on supporting temporarily upper portion simultaneously, and danger coefficient is big.
Disclosure of Invention
The utility model aims at overcoming prior art's defect, provide a interim bearing structure of steel construction, realize accomplishing support and adjustment to the steel construction on ground.
In order to solve the technical problem, the utility model discloses a realize like this:
the utility model provides a temporary bearing structure of steel construction which characterized in that: the device comprises a supporting base, an embedded steel plate, a supporting steel pipe, an adjusting steel pipe, a jack and an ear plate; the supporting base is formed by welding profile steels of three uniform distributions, an embedded steel plate is welded on the supporting base, the bottom of the adjusting steel pipe is welded with the supporting base, tightening bolts are arranged around the adjusting steel pipe, the supporting steel pipe is inserted into the adjusting steel pipe and fixed and limited through the tightening bolts, the jack is arranged between the supporting steel pipe and the supporting base, and lifting lugs for fixing the guy rope are arranged on the outer side of the upper portion of the supporting steel pipe.
The temporary support structure of the steel structure is characterized in that: the height adjusting range of the supporting steel pipe is within the range of 0-15 cm.
The utility model has the advantages that: (1) the temporary supporting base and the adjusting device are standard components and can be customized in a factory;
(2) after the temporary supporting height is in place, the temporary supporting height can be adjusted on the ground, and the risk of high-altitude adjustment of the temporary supporting height in the later steel structure installation stage is reduced;
(3) the height adjustment is carried out by adopting the screw jack, the adjustment range is flexible, the inflexible type of increasing the adjustment height of the steel base plate is avoided, and the installation height of the steel structure can be effectively ensured;
(4) the disassembly and the assembly are convenient, and the transportation and the reutilization can be realized;
the supporting and the adjustment of the steel structure can be completed on the ground, the danger of the aerial adjustment of the large-span steel structure is effectively reduced, the deflection of the large-span steel structure is controlled in a reasonable range, meanwhile, the temporary supporting can be used as a standard component, the factory is customized and processed, the large-span steel structure can be used and turned over when being transported to the field for assembly, the construction efficiency of the field can be effectively improved, and the good economic benefit is realized.

Detailed Description
As shown in fig. 1-6: a temporary supporting structure of a steel structure comprises a supporting base 1, an embedded steel plate 2, a supporting steel pipe 3, an adjusting steel pipe 4, a jack 5 and an ear plate 6; the supporting base is formed by welding three evenly distributed profile steels, an 8-fillet welded embedded steel plate is arranged on the supporting base, the bottom of the adjusting steel pipe is welded with the supporting base, tightening bolts are arranged on the periphery of the adjusting steel pipe, the supporting steel pipe is inserted into the adjusting steel pipe and is fixed and limited through tightening bolts 7, the jack is arranged between the supporting steel pipe and the supporting base, and lifting lugs for fixing the cable wind ropes are arranged on the outer side of the upper portion of the supporting steel pipe.
The temporary support is formed by welding 3 pieces of HW300X300X15X10 section steel, and embedded steel plates need to be pre-embedded in advance on the support surface before the base is in place and are connected with the base section steel in a welding mode. The adjusting steel pipe adopts a 356X10 steel pipe, the bottom of the supporting steel pipe is welded with the supporting base, and tightening bolts are arranged around the pipe and used for fixing and adjusting the steel pipe to play a limiting role. The adjusting steel pipe is inserted into the supporting steel pipe and fixed with the jacking bolt. And simultaneously fixing the cable rope at the upper part of the temporary supporting structure and tensioning the cable rope. And the bottom of each temporary supporting structure is provided with an adjusting jack for adjusting the height of the whole temporary support, so that the elevation of the upper structure can meet the design requirement. When the temporary support is detached, the jack is unloaded, the temporary support structure is separated from the steel structure, the cable rope is loosened, the cable rope is fixed with the crane hook head, then the puller bolt is loosened, the temporary support structure is detached, and meanwhile the support base is separated from the embedded steel plate. So that the temporary support structure can be used for support in the next place. The height adjusting range of the temporary supporting structure is within the range of 0-15 cm.
Further comprising the steps of:
and 2, embedding the support base embedded part before the concrete slab is poured. After the supporting base is installed, the embedded part is welded with the embedded part embedded in advance;
7, after the upper steel structure forms a stable system, unloading the jack to separate the temporary support from the steel structure, and loosening the cable wind rope to remove the temporary support steel pipe;
and 8, removing the temporary support base and adjusting the steel pipe.
