Abstract

The utility model discloses a steel support including a steel pipe and flanges, both ends of the steel pipe are respectively welded with a flange, the flanges and the steel pipe are concentric, the inner sides of the flanges are welded with the outer side of the steel pipe, the flanges are isometrically provided with bolt holes. Such a steel support can be predetermined and randomly combined, is easy to install and detach, at the same time, the steel support is reusable improving service lifetime.

Description

A kind of steel supports
Technical field
The utility model relates to subway support engineering technical field, relates in particular to a kind of steel and supports.
Background technology
Subway, building foundation pit supporting or road and bridge buttresses (frame) propping works, particularly road and bridge buttresses (frame) propping works are to use the rim of a bowl formula scaffold combination buttress (frame) as supportive body substantially.There is following problem in this technology: long construction period, and it is many to take human and material resources; Freight volume is big, installs, dismantles trouble; Loss is serious, causes waste (after the welding of material process, cutting, scrapping substantially), and occupied fund is more, and expense is higher.
The utility model content
The purpose of this utility model is to propose a kind of steel and supports, and can be scheduled to and combination arbitrarily, and assembling and disassembling is simple, can reuse simultaneously, has improved application life.
For reaching this purpose, the utility model by the following technical solutions:
A kind of steel supports, and comprises steel pipe and flange, and a flange is welded at the steel pipe two ends respectively, and flange is concentric with steel pipe, and the inboard of flange and the steel pipe outside weld together, and bolt hole equidistantly is set on the flange.
Also comprise reinforcing rib, reinforcing rib is the pentagon steel plate that comprises a right angle, one of them right-angle side and the welding of steel pipe outside vertical, and another right-angle side is vertical with flange to be welded, and outer reinforcing rib is evenly distributed on the steel pipe periphery, between bolt hole.
Steel pipe is straight seam welded steel pipe or spiral welded steel pipe.
Adopted the technical solution of the utility model, can realize batch production production, because build rule according to the subway road and bridge engineering, the steel supportive body that can design, produce different length, specification fully in advance makes up, and makes up arbitrarily according to requirement of engineering; Can reuse, after construction finishes dismounting, still can forward other building site week to and continue to use, thereby reduce construction cost; Suitability for industrialized production can reduce the cost significantly, and one-time investment can be made a profit for a long time, and economic benefit is very considerable; And easy to use, install, remove simple, increase economic efficiency.
Description of drawings
Fig. 1 is the elevation that steel supports in the utility model specific embodiment.
Fig. 2 is the lateral view that steel supports in the utility model specific embodiment.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Fig. 1 is the elevation that steel supports in the utility model specific embodiment.Fig. 2 is the lateral view that steel supports in the utility model specific embodiment.As depicted in figs. 1 and 2, this steel supports and comprises steel pipe 1, flange 2 and reinforcing rib 3.Wherein steel pipe is straight seam welded steel pipe or helix tube, weld a flange respectively at the two ends of steel pipe, flange is concentric with steel pipe, the inboard of flange and the steel pipe outside weld together, bolt hole 4 equidistantly is set, as the parts that connect or be connected between the steel supportive body on the flange with fixed end and active end.
Reinforcing rib is the pentagon steel plate that comprises a right angle, one of them right-angle side and the welding of steel pipe outside vertical, and another right-angle side is vertical with flange to be welded, and reinforcing rib is evenly distributed on the steel pipe periphery, between bolt hole.
In this specific embodiment the steel supportive body be applicable to subway, building foundation pit support engineering and road and bridge concrete pouring template buttress propping works such as (framves).This steel supportive body can divide different length, so that splicing adapts to the needs of engineering design, connects according to construction requirement and a plurality of steel supportive body and fixed end, active end matching and to be combined into steel and to prop up support integral.
When supporting, steel is used for subway, during the building foundation pit supporting construction, at first with expansion bolt concrete around angle bar frame and the foundation ditch being irritated stake combines closely, then steel being enclosed purlin places on each angle bar frame, form grit, again the good steel of splicing is propped up support integral, be lifted on respectively and be fixed on the corresponding steel of foundation ditch in advance and enclose on the link plate on the purlin, being installed in the movable position that steel supports the active end of an end with jack pair again pressurizes, make its stretching, reach the support degree of regulation up to it, location-plate (chock) is inserted active end fixedly fix in the gap, the supporting task is finished.
When the steel support is used to make up road and bridge buttress (frame) support, by designed distance and form of structure, the steel good splicing props up support integral, and vertical lifting encloses on purlin or the concrete Ji Liang at the steel that fixes in advance respectively, active end with jack pair one end pressurizes again, its stretching is decided to be, adjusts desired height, support securing device with steel then and make more fixing between the support, form buttress (support), go up at buttress (frame) then and lay i iron and template, placing of concrete, the support task is finished.After the construction completion, utilize jack with inner core jack-up, extract location-plate out, inner core is loosening, just can easily remove.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with the people of this technology in the disclosed technical scope of the utility model; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
