Abstract
The invention discloses a support rod which comprises an H-shaped steel, wherein rectangular flange boards are welded and fixed at two ends of the H-shaped steel; four connecting holes in two rows up and down are formed in each flange board; two lifting lug boards are arranged in a side groove of the H-shaped steel; three sides of each rectangular lifting lug board are welded and fixed onto a web plate and wing plates of the H-shaped steel respectively; the side groove of the H-shaped steel is divided into multiple sections by the lifting lug boards; at least one drain hole is formed each section of web plate of the H-shaped steel. The distance from each lifting lug board to the nearest flange board is 1/5 of the total length of the H-shaped steel. The flange boards are steel boards with thickness of 16 mm; the diameter of the connecting holes is 28mm; the space between every two upper-lower adjacent connecting holes is 100 mm; the space between every two left-right adjacent connecting holes is 100 mm. According to the technical scheme, the support rod is connected with other support components via standard assembling holes, the drain holes are formed for achieving the purpose of water drainage in a rainy day or an underwater construction environment so as to reduce corrosion of the components, the lifting lug boards are arranged to facilitate hoisting installation, and the support rod can be repeatedly used.
Description
Technical field
The present invention relates to high rigidity integrated prestress assembling pattern foundation pit supporting structure inner support system, particularly relate to a kind of support bar of high rigidity integrated prestress assembling pattern foundation pit supporting structure inner support system.
Background technology
In Soft Soil Foundation Pit engineering, steel concrete or steel pipe support supporting and protection structure, in order to reduce the distortion of foundation ditch, increase stability, at present conventional method is: increase reinforced concrete fortifield village purlin in the street size, increase the quantity of steel pipe support, reduce spacing etc.But this will increase the consumption of constructional materials greatly, decrease effective construction space in foundation ditch.Due to the steel support structure adopted at present, mainly using single shaped steel or steel pipe as brace summer, effective connection is not formed between every root type steel or steel pipe, can not as combining structure work, so their support rigidity is lower, the power that can bear is relatively limited, for the foundation ditch that span is larger, adopts existing steel shotcrete support to be difficult to control its distortion.These support members are owing to being much all make by site operation requirement, there is no the connection dimension of specification, cannot reach between all parts and exchange and general object, after causing foundation pit construction to complete, most of support component all becomes expendable consumed product, can not reuse.
Summary of the invention
In order to solve above-mentioned technical problem, the object of this invention is to provide a kind of support bar, being applicable to and other support component composite assemblies, can reusing.
To achieve the above object, present invention employs following technical scheme:
A kind of support bar, comprise the H profile steel of elongated rod shape, the two ends of H profile steel are welded and fixed the flanged plate of rectangle, flanged plate is provided with four connecting holes, four connecting holes are divided into two rows, often arrange about two one_to_one corresponding to arrange, 2 shackle plates are provided with in the lateral grooves of H profile steel, three limits of the shackle plate of rectangle are welded and fixed with the web of H profile steel and wing plate respectively, shackle plate has lifting hole(eyelet), the lateral grooves of described H profile steel is divided into multistage by shackle plate, and the H profile steel web of every section all has at least one drain hole.Shackle plate is 1/5 of H profile steel overall length to the distance of nearest flanged plate.The steel plate of described flanged plate to be thickness be 16mm; The diameter of connecting hole is 28mm, and the spacing of two neighbouring connecting holes is 100mm, and the spacing of two connecting holes that left and right is adjacent is 100mm.
The present invention, owing to have employed above technical scheme, is a welded construction, and with H profile steel for main material, two ends are welded with flanged plate, flanged plate is equipped with standard fitted position hole, with other angle braces, to support or column is connected.H profile steel middle pectoral plate is provided with drain hole, to reach the object of draining in rain weather or band water construction environment, reduces the corrosion of these parts.Because this component weight is heavier, with manually realizing assembling, cannot must use lifting appliance, for guaranteeing the safety ensureing in hoisting process to lift, shackle plate welds with three in the lateral grooves of H profile steel, ensures its intensity.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
Embodiment 1:
As Fig. 1, Fig. 2, Fig. 3, a kind of support bar shown in Fig. 4, comprise the H profile steel 1 of elongated rod shape, the two ends of H profile steel 1 are welded and fixed the flanged plate 2 of rectangle, flanged plate 2 is provided with four connecting holes 21, four connecting holes 21 are divided into two rows, often arrange about two one_to_one corresponding to arrange, 2 shackle plates 3 are provided with in the lateral grooves of H profile steel 1, three limits of the shackle plate 3 of rectangle are welded and fixed with the web of H profile steel 1 and wing plate respectively, shackle plate 3 has lifting hole(eyelet) 31, the lateral grooves of described H profile steel 1 is divided into multistage by shackle plate 3, H profile steel 1 web of every section all has a drain hole 11.Described shackle plate 3 is 1/5 of H profile steel 1 overall length to the distance of nearest flanged plate 2.Described flanged plate 2 for thickness be the steel plate of 16mm; As shown in Figure 4, the diameter of connecting hole 21 is 28mm, and the spacing of two neighbouring connecting holes 21 is 100mm, and the spacing of two connecting holes 21 that left and right is adjacent is 100mm.
The invention provides a kind of support bar.Inner support system mounting location props up and divides or top in the middle and upper part of foundation ditch, thus make the system of installation be suspended in foundation ditch, or with upright supports aloft, the effect of support bar is exactly by all angle braces, symmetry and support angle brace, connects into an entirety to the column of support, does not tilt.Can Multiple Type be designed according to total length difference, meet the assembling of different spacing.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
