Abstract

The invention discloses a connecting piece. The connecting piece comprises H-shaped steel; a plurality of connecting holes are formed in two side wing plates of the H-shaped steel; four connecting holes are in a group; the four connecting holes in every group are formed in four corners of a quadrate; two end surfaces of the H-shaped steel are cross sections and rectangular-shaped sealing plates are fixed at the two end surfaces of the H-shaped steel in a welding mode; a plurality of reinforced ribbed plates are arranged inside two side grooves of the H-shaped steel; the reinforced ribbed plates are arranged in a middle position of two right-and-left adjacent connecting holes which are in the same group; the reinforced ribbed plates are perpendicular to web plates and the two side wing plates of the H-shaped steel; the reinforced ribbed plates, the web plates and the two side wing plates are fixed in a welding mode; the two reinforced ribbed plates, which are close to two ends of the H-shaped steel, are provided with hanging holes; the web plate of the H-shaped steel, which is arranged between two adjacent reinforced ribbed plates, is provided with at least a draining hole. According to the technical scheme, the connecting piece is convenient to hoist and assemble and can be reused.

Description

Connector
Technical field
The present invention relates to high rigidity integrated prestress assembling pattern foundation pit supporting structure inner support system, particularly relate to a kind of connector.
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, at present conventional method is: 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, decrease 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, effective connection is not formed between every root type steel or steel pipe, can not as combining structure work, so their support rigidity is lower, the power that can bear is relatively limited, for the foundation ditch that span is larger, adopts existing steel shotcrete support to be difficult to control its distortion.These support members are owing to being much all make by site operation requirement, there is no the connection dimension of specification, cannot reach between all parts and exchange and general object, after causing foundation pit construction to complete, most of support component all becomes expendable consumed product, can not reuse.
Summary of the invention
In order to solve above-mentioned technical problem, the object of this invention is to provide a kind of connector, being applicable to and other support component composite assemblies, can reusing.
To achieve the above object, present invention employs following technical scheme:
Connector, comprise H profile steel, the wing plates on two sides of H profile steel all has multiple connecting hole, 4 connecting holes are one group, 4 connecting holes often in group are the distribution of square corner, the both ends of the surface of H profile steel are cross section and are welded with rectangle shrouding, multiple deep floor is respectively provided with in the grooves on two sides of described H profile steel, deep floor is arranged in the centre position of about same group adjacent two connecting holes, deep floor is vertical with wing plates on two sides with the web of H profile steel and be welded and fixed, lifting hole(eyelet) is had on two deep floors at H profile steel two ends, the web of the H profile steel between two adjacent deep floors has at least one drain hole.
As preferably, in 4 connecting holes often organized, the pitch of holes of neighbouring two connecting holes adjacent with 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 support (or angle brace) cannot meet stress condition, supporting object need be realized in the mode of combining structure with many supports, the present invention is owing to have employed above technical scheme, the effect of this connector is many support members to dress up an overall structure by specific spaced sets, by force dispersion in overall structure, the pressure that whole system be can bear improves greatly.The present invention, the web of H profile steel is provided with drain hole, to reach the object of draining in rain weather or band water construction environment, reduces the corrosion of these parts.Because this component weight is heavier, with manually realizing assembling, cannot must use lifting appliance, for guaranteeing the safety ensureing in hoisting process to lift, shackle plate welds with three in H profile steel lateral grooves, ensures its intensity.This standarized component can be used for inner support system enclose purlin, to multiple 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.Using the inner support system that this cover standard component assembles out in a specific way, meeting in prestressed situation, larger construction space can be saved, convenient construction.

Detailed description of the invention
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 Fig. 3, comprise H profile steel 3, the wing plates on two sides of H profile steel 3 all has multiple connecting hole 6, 4 connecting holes 6 are one group, 4 connecting holes 6 often in group are in the distribution of square corner, the both ends of the surface of H profile steel 3 are cross section and are welded with rectangle shrouding 1, multiple deep floor 4 is respectively provided with in the grooves on two sides of described H profile steel 3, deep floor 4 is arranged in the centre position of about same group adjacent two connecting holes 6, deep floor 4 is vertical with wing plates on two sides with the web of H profile steel 3 and be welded and fixed, lifting hole(eyelet) 2 is had on two deep floors 4 at H profile steel 3 two ends, the web of the H profile steel 3 between two adjacent deep floors 4 has at least one drain hole 5.
In the present embodiment, in 4 connecting holes 6 often organized, the pitch of holes of neighbouring two connecting holes 6 adjacent with 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 with H profile steel for main material, polylith deep floor, with square plate end socket, is welded in two ends inside H profile steel, part floor is provided with lifting hole(eyelet), and the web of H profile steel arranges multiple drain hole.The two sides wing plate of H profile steel arranges the blue pilot hole of multigroup method, and it is spacing between strut that group spacing is, and according to different strength demands, the connector of design different length, connector is longer, and group Kong Yue is many in flange assembling.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
