Abstract
The invention discloses an angle brace bracket for a high-rigidity monolithic pre-stressing assembly type internal support system for retaining and protection of a foundation pit. The bracket comprises an isosceles right-triangle reinforcing plate, a first side plate, a second side plate and a base plate, wherein the first side plate, the second side plate and the base plate form a barrel-shaped structure with an isosceles right-triangle cross section through welding; the isosceles right-triangle reinforcing plate is arranged in the barrel-shaped structure and has three sides respectively fixed with the first side plate, the second side plate and the base plate through welding; eight connecting holes A are formed in the base plate in an upper and a lower row, the four connecting holes A in each row are in isometric distribution, and the holes in the upper row are in one-to-one correspondence with those in the lower row. Due to the adoption of the technical scheme, the bracket can be used in combination with other support parts, is firm and stable in supporting, 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 angle brace bracket of a kind of high rigidity integrated prestress assembling pattern foundation pit supporting structure inner support system.
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 is stable, and method commonly used is at present: increase the reinforced concrete fortifield village purlin quantity of size, increase steel pipe support in the street, minimizing spacing etc.But this will increase the consumption of constructional materials greatly, also reduce effective construction space in the foundation ditch.Because 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 the 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 all being to make by the site operation requirement a lot, the connection dimension that does not have standard can't reach between all parts and to exchange and general purpose, cause foundation pit construction to finish after, 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 angle brace bracket of a kind of high rigidity integrated prestress assembling pattern foundation pit supporting structure inner support system, be fit to and other support component composite assemblies, can reuse.
To achieve the above object, the present invention has adopted following technical scheme:
The angle brace bracket of high rigidity integrated prestress assembling pattern foundation pit supporting structure inner support system, comprise the isosceles right triangle stiffener, the first waist side plate, the second waist side plate and bilge ways, the first waist side plate, the second waist side plate and bilge ways welding surround the barrel-like structure that a cross section is isosceles right triangle, the inside of this barrel-like structure arranges the isosceles right triangle stiffener, three limits of isosceles right triangle stiffener respectively with the first waist side plate, the second waist side plate and bilge ways are welded and fixed, wherein, described bilge ways is provided with eight connecting hole A, eight connecting hole A are divided into two rows, four equidistant settings of every row and corresponding one by one up and down; Described the second waist side plate is provided with four connecting hole B, and four connecting hole B are divided into two rows, two up and down one by one corresponding settings of every row.
As preferably, the base of described isosceles right triangle stiffener is weldingly fixed on the two rows connecting hole A centre position of bilge ways, and a right-angle side of described isosceles right triangle stiffener is weldingly fixed on the two rows connecting hole B centre position of the second waist side plate.
As preferably, described isosceles right triangle stiffener center has drain hole.
As preferably, described isosceles right triangle stiffener is that thickness is the steel plate of 8～12mm, and described the first waist side plate, the second waist side plate and bilge ways are the steel plate that thickness is 14～18mm.
As preferably, the diameter of connecting hole A is 24～32mm on the described bilge ways, and the spacing of two neighbouring connecting hole A is 180～220mm, and the spacing of two connecting hole A that the left and right sides is adjacent is 80～120mm.
As preferably, the diameter of connecting hole B is 24～32mm on described the second waist side plate, and the spacing of two neighbouring connecting hole B is 180～220mm, and the spacing of two connecting hole B that the left and right sides is adjacent is 180～220mm.
The present invention has been owing to having adopted above technical scheme, triangular support structure, and base and wherein on the right-angle side standard size connecting hole is arranged generally is assemblied in enclosing on the purlin of corner, for the installation of angle brace.These parts be inner support system angle brace when applying prestressing force pedestal.Triangular design is stable structure type in all structures, also is best force structure, when angle brace applies prestressing force, can better bear the shearing force of 45 degree directions, and can not be out of shape.Adopt gauge orifice and standard profile size design, easy accessibility reaches and exchanges general purpose.
