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 a kind of connector.
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 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, also reduce effective construction space in foundation ditch.Due to the steel support structure that adopts at present, mainly with single shaped steel or steel pipe as brace summer, do not form effectively between every shaped steel or steel pipe 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 a kind of connector, be fit to and other support component composite assemblies, can reuse.
To achieve the above object, the present invention has adopted following technical scheme:
connector, comprise H shaped steel, all have a plurality of connecting holes on the wing plates on two sides of H shaped steel, 4 connecting holes are one group, 4 connecting holes in every group are square four jiaos of distributions, the both ends of the surface of H shaped steel are the cross section and are welded with the rectangle shrouding, respectively be provided with a plurality of deep floors in the grooves on two sides of described H shaped steel, deep floor is arranged in the centre position of two adjacent connecting holes of same group of left and right, the web of deep floor and H shaped steel is vertical with wing plates on two sides and be welded and fixed, have lifting hole(eyelet) on two deep floors near H shaped steel two ends, have at least one drain hole on the web of the H shaped steel between two adjacent deep floors.
As preferably, in 4 connecting holes of every group, the pitch of holes of neighbouring two connecting holes adjacent with the left and right is 180mm to 220mm, and the group spacing of two groups of adjacent connecting holes is 280mm to 320mm, and the diameter of connecting hole is 25mm to 30mm.
As preferably, the thickness of described rectangle shrouding is 10mm to 15mm.
In medium-sized or above foundation pit support system, single or many to the support (or angle brace) can't satisfy stress condition, need to realize the supporting purpose with many supports in the mode of combining structure, the present invention is owing to having adopted above technical scheme, the effect of this connector is many support members are dressed up an overall structure by specific spaced sets, on overall structure, the pressure that whole system can bear is improved greatly force dispersion.The present invention is provided with drain hole on the web of H shaped steel, 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 H shaped steel lateral grooves with three welding, guarantee its intensity.This standarized component can be used for the inner support system enclose purlin, to a plurality of positions such as support, angle braces, these parts have Multiple Type, can realize the matching requirements of plurality of specifications foundation ditch.Because these parts are the standard size parts, easy accessibility can repeatedly reuse, and reaches the purpose of saving construction cost.The inner support system that uses this cover standard component to assemble out with ad hoc fashion satisfying in prestressed situation, can save larger construction space, convenient construction.

The specific embodiment
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, connector shown in Figure 3, comprise H shaped steel 3, all have a plurality of connecting holes 6 on the wing plates on two sides of H shaped steel 3, 4 connecting holes 6 are one group, 4 connecting holes 6 in every group are square four jiaos of distributions, the both ends of the surface of H shaped steel 3 are the cross section and are welded with rectangle shrouding 1, respectively be provided with a plurality of deep floors 4 in the grooves on two sides of described H shaped steel 3, deep floor 4 is arranged in the centre position of two adjacent connecting holes 6 of same group of left and right, the web of deep floor 4 and H shaped steel 3 is vertical with wing plates on two sides and be welded and fixed, have lifting hole(eyelet) 2 on two deep floors 4 near H shaped steel 3 two ends, have at least one drain hole 5 on the web of the H shaped steel 3 between two adjacent deep floors 4.
In the present embodiment, in 4 connecting holes 6 of every group, the pitch of holes of neighbouring two connecting holes 6 adjacent with the left and right is 180mm to 220mm, and the group spacing of two groups of adjacent connecting holes 6 is 280mm to 320mm, and the diameter of connecting hole 6 is 25mm to 30mm.The thickness of described rectangle shrouding 1 is 10mm to 15mm.
This connector is a welded construction, and take H shaped steel as main material, two ends are with the square plate end socket, the inboard welding of H shaped steel polylith deep floor, and the part floor is provided with lifting hole(eyelet), and a plurality of drain holes are set on the web of H shaped steel.The two sides wing plate of H shaped steel arranges the blue pilot hole of multigroup method, and it is spacing between strut that the group spacing is, according to different strength demands, and the connector of design different length, connector is longer, and flange assembled group hole is more.
It is emphasized that: above is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
