Abstract
A kind of Two bors d's oeuveres channel steel upright post, including 2 symmetrical product channel steels, 2 steel plate batten plates, it is characterized in that the specifications and models of 2 product channel steels are identical, the equal length of channel steel, and channel steel top position has round hole for hoist；Steel batten plate uses elongate steel plate, and the spacing of steel batten plate is equal, and steel batten plate is separately connected adjacent wing plate between 2 product channel steels, is connected using welding manner；The steel column is anchored in the top rebars concrete of cast-in-situ bored pile, and when Construction of Supporting vertically connects with reinforced concrete support, is partially anchored into reinforced concrete support, is played spacer bar concrete horizontal support system.
Description
Technical field
The utility model relates to a kind of Two bors d's oeuveres channel steel upright post in the realm of building construction, be primarily adapted for use in industry with it is civilian
The vertical supporting of deep-foundation pit engineering reinforced concrete inner support in the Underground Constructions such as building.
Background technique
Foundation pit area is constructed more than certain scale in deep foundation pit of construction engineering at present, to ensure Underground Construction safety,
Foundation pit supporting system all uses reinforced concrete inner support, and this support system with reinforced concrete inner support requires to erect
To support, vertical supporting has been generally used cast-in-situ bored pile tip cutting lattice-type steel column at present, by steel column and level
Support is connected, with support level reinforced concrete inner support.The angle steel that steel column mostly uses greatly four same sizes isometric at present
It is manufactured by welding batten plate, four angle steel are in four corner locations of steel column the characteristics of this steel column, adjacent
Angle steel between welding steel batten plate, need to weld 4 blocks of steel plate batten plates at every one of batten plate, welding workload is very big, welds matter
Amount requires height, and quality control difficulty is big, and expense material is taken a lot of work, and the particularly disadvantageous Foundation Pit Construction with duration anxiety is tired to stir construction
Technology and administrative staff.
Summary of the invention
In order to solve the deficiency that current steel column expense material is taken a lot of work, reduce welding workload, we have devised a kind of Two bors d's oeuveres
Channel steel upright post is made of 2 symmetrical product channel steels, 2 steel plate batten plates, it is characterized in that the specifications and models of 2 product channel steels are identical,
The equal length of channel steel, and channel steel top position has round hole for hoist；Steel batten plate uses elongate steel plate, the spacing phase of steel batten plate
It is separately connected adjacent wing plate between 2 product channel steels Deng, steel batten plate, is connected using welding manner；The steel column is anchored at drill-pouring
In the top rebars concrete of stake, when Construction of Supporting, vertically connects with reinforced concrete support, partially anchors into armored concrete branch
In support, spacer bar concrete horizontal support system is played.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing.
Fig. 1 drawing in side sectional elevation
1. channel steel, 2. steel batten plate, 3. weld seam in figure；
Fig. 2 front view
1. channel steel, 2. steel batten plate, 3. weld seam, 4. hole for hoist in figure.
Specific embodiment
1, according to 2 product of channel steel of steel column design size selection dimension in foundation pit enclosure in factory, and by channel steel
End is polished flat；
2, several is set horizontally-supported in factory, is then shelved on the isometric channel steel both wings of 2 product relatively horizontally-supported
On, check channel steel levelness, it is ensured that 2 product channel steel both wings are horizontal；
3,2 product channel steel positions are adjusted, it is ensured that processing column size is primary with design requirement, and welds end batten plate, tentatively
Fix the position of 2 product channel steels；
4, steel batten plate is welded according to design disposed at equal distance, welding uses manual electric arc welding, and throat depth is not small
10mm；；
5, steel batten plate is equidistant be welded and fixed after, the position of hole for hoist is determined according to strut length；
6, the welding quality inspection of steel batten plate is carried out, up-to-standard steel upright post hoisting is at workshop finished product acceptance(check)；
7, steel column bottom is anchored into steel reinforcement cage before the installation of construction site drilling bored concrete pile final section steel reinforcement cage, then
It is transferred to together until designed elevation in stake holes, and fixed；
8, drill-pouring pile concreting is carried out, steel column is just fixed in cast-in-situ bored pile after concrete hardening.
