Abstract
The invention discloses a tie bar for a supporting system in a high-rigidity integral prestressed fabricated foundation pit support. The tie bar comprises a long-bar-shaped H-beam, rectangular flange plates are welded and fixed at two ends of the H-beam, four connecting holes are formed in each flange plate and divided into an upper row and a lower row, the two connecting holes in each row are in up-down one-to-one correspondence, two to four lifting lug plates are arranged in side grooves of the H-beam, three edges of each rectangular lifting lug plate are welded and fixed with a web and flanges of the H-beam respectively, and each lifting lug plate is provided with a lifting hole. Each side groove of the H-beam is partitioned into multiple sections by the lifting lug plates, and at least one drain hole is formed in the web of the H-beam in each section. According to the technical scheme, holes in standard assembling sizes are designed to be connected with other angle braces, diagonal braces or columns, the drain holes are provided so as to achieve the purpose of water draining in rainy days or construction environments with water, corrosion to parts is reduced, and the lifting lug plates are arranged for the convenience of lifting and can be used repeatedly.
Description
Technical field
The present invention relates to high rigidity integrated prestress assembling pattern foundation pit supporting structure inner support system, relate in particular to the pull 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 reduce effective construction space in foundation ditch.Due to the steel support structure that adopts at present, mainly using single shaped steel or steel pipe as brace summer, between every shaped steel or steel pipe, do not form effectively and connect, can not be as combining structure work, so their support rigidity is lower, the power that can bear is relatively limited, for the larger foundation ditch of span, adopts 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 invention is to provide the pull bar that a kind of high rigidity integrated prestress assembling pattern foundation pit supporting structure inner support system is used, be suitable for and other support component composite assemblies, can reuse.
To achieve the above object, the present invention has adopted following technical scheme:
the pull bar that high rigidity integrated prestress assembling pattern foundation pit supporting structure inner support system is used, 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, in the lateral grooves of H shaped steel, be provided with 2 to 4 shackle plates, 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 have at least one drain hole.
As preferably, in the lateral grooves of described H shaped steel, be provided with 2 shackle plates, shackle plate is 1/6～1/4 of H shaped steel overall length to the distance of nearest flanged plate.
As preferably, described flanged plate is that thickness is the steel plate of 14～18mm; The diameter of connecting hole is 26～30mm, and the spacing of two neighbouring connecting holes is 80～120mm, and the spacing of two connecting holes that left and right is adjacent is 80～120mm.
The present invention, owing to having adopted above technical scheme, is a welded construction, and take H shaped steel as main material, two ends are welded with flanged plate, on flanged plate, be equipped with standard fitted position hole, with other angle braces, support or column are connected.On H shaped steel middle pectoral plate, be provided with drain hole, so that at rain weather or in the water construction environment, reach the purpose of draining, 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.
