Abstract
The utility model discloses a connection end for a whole prestressed fabricated support system in a foundation pit support. 12 connection holes are opened in flanges on two sides of an H-shaped steel, 4 connection holes serve as a group, the four connection holes in each group are distributed at four corners in a square shape, space between holes in the groups is 200mm, and space between the groups is 300mm, and the diameters of the connection holes are 28mm. Two end surfaces of the H-shaped steel are cross sections, and a rectangular seal plate 12mm in thickness is welded and fixed on each of the two end surfaces. Two lifting lug plates and a reinforcing plate are arranged in a groove of each of the two sides of the H-shaped steel, the distance from the lifting lug plate to the nearest rectangular seal plate is 1/10 of the overall length of the H-shaped steel, the lifting lug plates and a web plate and the wing plates on two sides of the H-shaped steel are perpendicular and are welded and fixed, lifting holes are opened in the lifting lug plates, the reinforcing plates are arranged in the middle of the H-shaped steel and are perpendicular to and welded and fixed with the web plate and the wing plates on two sides of the H-shaped steel, and a drainage hole is opened in each of the two sides of the web plate of the H-shaped steel on two sides of each reinforcing plate. The connection end is convenient to lift and assemble and capable of being used repeatedly.
Description
Technical field
The utility model relates to high rigidity integrated prestress assembling pattern foundation pit supporting structure inner support system, relates in particular to a kind of integrated prestress assembling pattern foundation pit supporting structure inner support system connection end.
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, and conventional method 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 adopting 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 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 site operation requirement, the connection dimension that there is no standard, cannot reach between all parts and exchange and general object, 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 integrated prestress assembling pattern foundation pit supporting structure inner support system connection end, is applicable to and other support component composite assemblies, can reuse.
To achieve the above object, the utility model has adopted following technical scheme:
Integrated prestress assembling pattern foundation pit supporting structure inner support system connection end, comprise H shaped steel, in the wing plates on two sides of H shaped steel, all have 12 connecting holes, 4 connecting holes are one group, 4 connecting holes in every group are square four jiaos of distributions, the pitch of holes of neighbouring two connecting holes adjacent with left and right is 200mm, the group spacing of connecting hole is 300mm, the diameter of connecting hole is 28mm, the both ends of the surface of H shaped steel are cross section and are welded with the rectangle shrouding that thickness is 12mm, in the grooves on two sides of described H shaped steel, be respectively provided with two shackle plates and a stiffener, shackle plate is 1/10 of H shaped steel overall length to the distance of nearest rectangle shrouding, the web of shackle plate and H shaped steel is vertical with wing plates on two sides and be welded and fixed, on shackle plate, have lifting hole(eyelet), stiffener is positioned at the centre position of H shaped steel, the web of stiffener and H shaped steel is vertical with wing plates on two sides and be welded and fixed, on the web of described H shaped steel, in the both sides of stiffener, all have a drain hole.
In medium-sized or above foundation pit support system, single or many to support (or angle brace) cannot meet stress condition, need in the mode of combining structure, realize supporting object with many supports, the utility model is owing to having adopted above technical scheme, the effect of this connection end is many support members to dress up an overall structure by specific spaced sets, on overall structure, the pressure that whole system can bear is improved greatly force dispersion.The utility model is provided with drain hole on the web of H shaped steel, so that at rain weather or reach the object of draining in water construction environment, reduces the corrosion of these parts.Because of this component weight heavier, cannot be with manually realizing assembling, must use lifting appliance, 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 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 standard size parts, easy accessibility, can repeatedly reuse, and reaches the object of saving construction cost.The inner support system of using this cover standard component to assemble out with ad hoc fashion, meeting 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 utility model is made a detailed explanation.
Embodiment 1:
As Fig. 1, Fig. 2, integrated prestress assembling pattern foundation pit supporting structure inner support system connection end shown in Fig. 3, comprise H shaped steel 3, in the wing plates on two sides of H shaped steel 3, all have 12 connecting holes 6, 4 connecting holes 6 are one group, 4 connecting holes 6 in every group are square four jiaos of distributions, the pitch of holes of neighbouring two connecting holes 6 adjacent with left and right is 200mm, the group spacing of connecting hole 6 is 300mm, the diameter of connecting hole 6 is 28mm, the both ends of the surface of H shaped steel 3 are cross section and are welded with the rectangle shrouding 1 that thickness is 12mm, in the grooves on two sides of described H shaped steel 3, be respectively provided with two shackle plates 2 and a stiffener 4, shackle plate 2 is 1/10 of H shaped steel 3 overall lengths to the distance of nearest rectangle shrouding 1, the web of shackle plate 2 and H shaped steel 3 is vertical with wing plates on two sides and be welded and fixed, on shackle plate 2, have lifting hole(eyelet), stiffener 4 is positioned at the centre position of H shaped steel 3, the web of stiffener 4 and H shaped steel 3 is vertical with wing plates on two sides and be welded and fixed, on the web of described H shaped steel 3, in the both sides of stiffener 4, all have a drain hole 5.
