Description

A kind of increase the device of single bracing members stability in foundation ditch
Technical field
This utility model relates to a kind of increasing the device of single bracing members stability in foundation ditch, application In deep-foundation pit engineering fields such as building engineering, railway traffic engineering, port and pier, it is suitable for In using the bracing members deep-foundation pit engineering as inner support system.
Background technology
In Deep Foundation Pit of Metro Stations engineering, bracing members as the inner support system of base pit engineering is Relatively conventional supporting construction pattern.Support according to base pit engineering is arranged, it will usually steel occur Supporting longer situation, when steel support shaft power is bigger, the stable calculation of support is difficult to meet Design requirement.In this case, it is common that use the mode setting up interim column with connection beam Reduce the computational length of support thus increase the stability of bracing members.And for single bracing members In the case of longer, if using the mode arranging connection beam in the middle of two interim columns to solve Single bracing members stability problem will necessarily increase construction costs, and difficulty of construction increases, executes Work convenience is poor.
Summary of the invention
The purpose of this utility model is that providing a kind of increases single bracing members stability in foundation ditch Device.It utilizes fixing post and steel bracket to retrain bracing members, limits bracing members Displacement, solves the stability problem of single long bracing members, adds the safety of base pit engineering, Save construction investment.
The purpose of this utility model is reached by following measure: single in a kind of increase foundation ditch The device of root bracing members stability, including horizontally disposed bracing members, it is characterised in that: also wrap Include fixing post vertically disposed with bracing members, described fixing post is fixed with steel bracket, described steel Support is placed on steel bracket.
Further, described steel bracket includes plane steel plate, steel supporting plate and curved plate, described Plane steel plate is welded on fixing post, and the back side of described plane steel plate is fixed with at least one steel torr Plate, described plane steel plate is disposed with at least one curved plate, and described bracing members is placed on arc On shape steel plate, the arcwall face of described curved plate fits with the lower surface of bracing members.
Further, described steel supporting plate is the most trapezoidal, and two right-angle sides of described steel supporting plate are respectively Weld mutually with fixing post and plane steel plate.
Further, described curved plate is welded on plane steel plate.
Further, the quantity of described curved plate is two, and the quantity of described steel supporting plate is two Individual, the position of two described curved plates is corresponding with the position of two described steel supporting plates respectively.
Further, described bracing members is provided with at least one U-shaped anchor ear, described U-shaped armful The kink of hoop and the upper surface abutting contact of bracing members, described bracing members is solid by U-shaped anchor ear It is scheduled on plane steel plate.
Further, the two ends of described U-shaped anchor ear are screwed connection post, two connections Post is each passed through circular hole corresponding on plane steel plate the nut matched that is spirally connected.
Further, described fixing post is square lattice column, and the lower end of lattice column is fixed on base In the stake at the end, hole, hole.
This utility model has the advantage that as follows: bracing members is shelved on arc-shaped steel by this utility model On plate, curved plate, plane steel plate, steel supporting plate constitute steel bracket on fixing post, form one Individual stable entirety, bracing members is fixed by U-shaped anchor ear, can effectively limit steel The displacement supported, thus increase the stability of bracing members.It solve single long bracing members flat Stability problem inside and outside face, adds the safety of base pit engineering, saves construction investment. This utility model has design and easy construction, economical rationality, increase foundation ditch general safety etc. are excellent Point, it is adaptable to bracing members is as the deep-foundation pit engineering of inner support system, in subway foundation pit engineering Have a good application prospect.

Detailed description of the invention
Describe performance of the present utility model below in conjunction with the accompanying drawings in detail, but it be not intended that right Restriction of the present utility model, only illustrates.Simultaneously by explanation, of the present utility model excellent Point will become clearer from easy to understand.
As shown in Figure 1 and Figure 2, a kind of increase the device of single bracing members stability in foundation ditch, Including horizontally disposed bracing members 5 and fixing post vertically disposed with bracing members 5, fixing post is Square lattice column 6, lattice column 6 lower end is fixed in the stake at the bottom of Foundation Pit.On fixing post admittedly Surely steel bracket, steel bracket is had to include plane steel plate 4, steel supporting plate 1 and curved plate 2, plane Steel plate 4 is welded on lattice column 6, the back side of plane steel plate 4 be disposed with two be parallel to each other between Every the steel supporting plate 1 arranged, steel supporting plate 1 is the most trapezoidal, and two right-angle sides of steel supporting plate 1 are respectively Weld with lattice column 6 and plane steel plate 4 phase.It is disposed with two on plane steel plate 4 to be parallel to each other Spaced curved plate 2, curved plate 2 is welded on plane steel plate 4, curved plate 2 for the spacing of bracing members 5 and support.Two intervals that are parallel to each other it are provided with on bracing members 5 The U-shaped anchor ear 3 arranged, bracing members 5 is fixed on plane steel plate 4 by U-shaped anchor ear 3. The position of two curved plates 2 is corresponding with the position of two steel supporting plates 1 respectively, adds further The stability of strong supporting construction.In actual applications, bracing members 5 can the most multiple rows of be parallel to each other Arrange, then on lattice column 6, the multiple and multiple rows of bracing members 5 being parallel to each other of space set matches The structure increasing bracing members stability closed.
As it is shown on figure 3, bracing members 5 is placed on curved plate 2, the arc of curved plate 2 Face fits with the lower surface of bracing members 5, supports 5 for stablizing supporting steel, and in certain journey Moving left and right of bracing members 5 is limited on degree.The kink of U-shaped anchor ear 3 is upper with bracing members 5 Surface abutting contact, limits the displacement of bracing members 5 effectively.
As shown in Figure 4, the two ends of described U-shaped anchor ear 3 are screwed connection post, two Connect post and be each passed through circular hole corresponding on plane steel plate 4 nut matched that is spirally connected.
