Abstract

The utility model discloses a supporting rod which comprises H-type steel. Rectangular flange plates are fixedly welded at the two ends of the H-type steel. Four connection holes divided into an upper row and a lower row are formed in each flange plate. Two lifting lug plates are arranged in grooves in the lateral sides of the H-type steel. Three edges of each rectangular lifting lug plate and a web and wing plates of the H-type steel are fixedly welded. The grooves in the lateral sides of the H-type steel are segmented into a plurality of sections through the lifting lug plates, and at least one water discharging hole is formed in each section of the web of the H-type steel. The distance between each lifting lug plate and the nearest flange plate is one fifth of the total length of the H-type steel. The flange plates are steel plates with the thicknesses of 16mm. The diameters of the connecting holes are 28mm. The interval between every two up-and-down adjacent connecting holes is 100mm. The interval between every two left-and-right adjacent connecting holes is 100mm. By means of the technical scheme, standard assembly holes are used for being connected with other supporting parts, the water discharging holes are formed so that the water discharging aim can be conveniently achieved in rain weather or a construction environment with water, corrosion to the parts is reduced, the lifting lug plates are arranged so that lifting assembling can be conveniently achieved, and the supporting rod can be repeatedly used.

Description

A kind of support bar

Technical field

The utility model relates to high rigidity integrated prestress assembling pattern foundation pit supporting structure inner support system, relates in particular to the support bar that a kind of high rigidity integrated prestress assembling pattern foundation pit supporting structure inner support system is used.

Background technology

In the 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, and method commonly used is at present: increase the reinforced concrete fortifield village purlin quantity of size, increase steel pipe support in the street, reduce spacing etc.But this will increase the consumption of constructional materials greatly, also reduced 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, do not form effectively and connect between every shaped steel or steel pipe, can not be as combining structure work, so their support rigidity is lower, the power can bear is relatively limited, and the larger foundation ditch for span, adopt existing steel shotcrete support to be difficult to control its distortion.These support members are owing to being all much to make by the site operation requirement, the connection dimension that there is no standard, can't reach between all parts and exchange and general purpose, after causing foundation pit construction to complete, most of support components all become expendable consumed product, can not reuse.

Summary of the invention

In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of support bar, is applicable to and other support component composite assemblies, can reuse.

To achieve the above object, the utility model has adopted following technical scheme:

A kind of support bar, the H shaped steel that comprises elongated rod shape, the two ends of H shaped 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, two corresponding settings one by one up and down of every row, be provided with 2 shackle plates in the lateral grooves of H shaped steel, three limits of the shackle plate of rectangle are welded and fixed with web and the wing plate of H shaped steel respectively, shackle plate has lifting hole(eyelet), the lateral grooves of described H shaped steel is divided into multistage by shackle plate, on the H shape steel web of every section, all has at least one drain hole.Shackle plate is 1/5 of H shaped steel overall length to the distance of nearest flanged plate.Described flanged plate is the steel plate that thickness is 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 utility model, owing to having adopted above technical scheme, is a welded construction, take H shaped steel as main material, and two ends are welded with flanged plate, be equipped with standard fitted position hole on flanged plate, with other angle braces, support or column are connected.Be provided with drain hole on H shaped steel middle pectoral plate, so that at rain weather or reach the purpose of draining in the water construction environment, reduce the corrosion of these parts.Heavier because of this component weight, can't must use lifting appliance with manually realizing assembling, be the safety of guaranteeing to guarantee in hoisting process lifting, shackle plate in the lateral grooves of H shaped steel with three welding, guarantee its intensity.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is made a detailed explanation.

Embodiment 1:

As Fig. 1, Fig. 2, Fig. 3, a kind of support bar shown in Fig. 4, the H shaped steel 1 that comprises elongated rod shape, the two ends of H shaped 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, two corresponding settings one by one up and down of every row, be provided with 2 shackle plates 3 in the lateral grooves of H shaped steel 1, three limits of the shackle plate 3 of rectangle are welded and fixed with web and the wing plate of H shaped steel 1 respectively, shackle plate 3 has lifting hole(eyelet) 31, the lateral grooves of described H shaped steel 1 is divided into multistage by shackle plate 3, all have a drain hole 11 on H shaped steel 1 web of every section.Described shackle plate 3 is 1/5 of H shaped steel 1 overall length to the distance of nearest flanged plate 2.The steel plate that described flanged plate 2 is 16mm for thickness; 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 utility model provides a kind of support bar.Inner support system installation site is propped up in the middle and upper part of foundation ditch and is divided or top, thereby the system of installing is suspended in foundation ditch, or by upright supports aloft, the effect of support bar is exactly by all angle braces, symmetry and support angle brace, the column that supports use is connected into to an integral body, does not tilt.Can design Multiple Type according to the total length difference, meet the assembling of different spacing.

It is emphasized that: above is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
