Abstract
The utility model discloses a strut foundation ditch and enclose purlin structure of shearing, including and surrounding the perpendicular retaining pile who sets up of foundation ditch lateral wall and level setting at the inboard purlin that encloses of retaining pile, be provided with horizontal supports steel pipe and diagonal bracing steel pipe on enclosing the purlin, be close to on the retaining pile of diagonal bracing steel pipe both ends department respectively the dowels that even interval was provided with a plurality of big or small unanimities, the one end and the retaining pile of dowel link firmly mutually, and the other end runs through and encloses purlin and the nut through the tip setting and enclose the purlin fastening connection. The utility model has the advantage of simple structure, simple to operate. Through the dowel that sets up on the retaining pile being close to diagonal bracing steel pipe both ends department with enclose the purlin fastening connection, it is even as an organic whole with retaining pile that the messenger encloses the purlin, ensures to enclose the purlin and undertake the horizontal shear that the diagonal bracing steel pipe brought jointly with retaining pile, improves the steadiness that encloses the purlin, simultaneously, it is even as an organic whole to enclose purlin and retaining pile through the dowel, has not only reduced the construction degree of difficulty but also reduced the fracture probability, guarantees the safety of job site.
Description
Technical field
The utility model relates to supporting foundation pit, especially relates to a kind of supporting foundation pit and encloses purlin shear structure.
Background technology
Foundation ditch is by the heatable adobe sleeping platform that substrate absolute altitude and basic plane size are excavated in basic engineering position.Foundation ditch is divided into non-support foundation ditch and has supporting foundation pit.When foundation pit walls soil property is unstable, and when having underground water mitigation; It is excessive that slope mode earth excavation engineering quantity is put in employing, time uneconomical; Being subject to construction plant or adjacent structure restriction, when can not adopt the mode of putting slope excavation, for ensureing that caving in does not appear in foundation ditch, need supporting foundation pit having been adopted.
There is the supporting and protection structure of supporting foundation pit to comprise to be close to the vertically disposed fender post of foundation pit side-wall and be horizontally set on and enclose purlin inside fender post, had the supporting steel pipe of reinforcement effect enclosing erection between purlin; According to the difference of foundation pit structure, supporting steel pipe has perpendicular to enclosing that purlin arranges, also has oblique layout.When the oblique layout of supporting steel pipe, supporting steel pipe with enclose purlin junction along enclosing on purlin length direction and can be subject to very huge horizontal shear, now just easily there is supporting steel pipe fracture or enclose the phenomenons such as purlin distortion; For the generation of anti-phenomenon here, existing is all arrange between adjacent two fender posts and enclose fixture block that purlin is connected and offset horizontal shear along enclosing on purlin length direction; Be connected together between fixture block and fender post in this kind of method, through after a while, the soil property around fixture block is under the effect being subject to horizontal shear for a long time, and what can slowly become is loose; Now, enclosing the horizontal shear that purlin is subject to cannot pass to fender post completely, supporting steel pipe still can be caused to rupture or enclose the phenomenon of purlin distortion; Meanwhile, fixture block is connected by welding with enclosing between purlin, is subject to horizontal shear for a long time and also easily makes it disconnect, affect the transmission of horizontal shear.
Summary of the invention
The utility model object is to provide a kind of structure simple and the supporting foundation pit that effectively can improve supporting effect encloses purlin shear structure.
For achieving the above object, the utility model can take following technical proposals:
Supporting foundation pit described in the utility model encloses purlin shear structure, comprise around the vertically disposed fender post of foundation pit side-wall and be horizontally set on and enclose purlin inside described fender post, described enclosing on purlin is provided with cross binding steel pipe and skewed horizontal load steel pipe, on the described fender post at described skewed horizontal load steel pipe two ends place, uniform intervals is provided with multiple dowel of the same size respectively, one end of described dowel is connected mutually with described fender post, enclose purlin described in the other end runs through and the nut arranged by end with enclose purlin and be fastenedly connected.
Described dowel extension is arranged in described fender post, and its development length is more than or equal to 400mm.
described in eachdowel number on fender post is 9, by three row three row uniform intervals arrangements.
Spacing in described vertical direction or horizontal direction between adjacent two dowels is 150mm.
The diameter of described dowel is 22mm.
The utility model advantage is that structure is simple, easy for installation.By arranging on the fender post near skewed horizontal load steel pipe two ends place and enclosing the dowel that purlin is fastenedly connected, make to enclose purlin with fender post is connected as a single entity, guarantee to enclose the horizontal shear that purlin and fender post shared skewed horizontal load steel pipe bring, the steadiness of purlin is enclosed in raising; Meanwhile, will purlin be enclosed by dowel and fender post is connected as a single entity, and both reduce difficulty of construction and turn reduced fracture probability, ensure the safety of job site.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the connection diagram of enclosing purlin and fender post in the utility model.
Detailed description of the invention
As shown in Figure 1, 2, supporting foundation pit described in the utility model encloses purlin shear structure, comprises around the vertically disposed fender post of foundation pit side-wall 1 and is horizontally set on and encloses purlin 2 inside fender post, encloses purlin 2 and is close to fender post 1 and arranges; According to the difference of foundation ditch situation, be provided with cross binding steel pipe 3 and skewed horizontal load steel pipe 4 enclosing on purlin 2, on the fender post 1 near skewed horizontal load steel pipe 4 two ends place, uniform intervals is provided with multiple dowel 5(dowel 5 model of the same size is respectively HRB400, and its diameter is 22mm); One end extension of dowel 5 is arranged in fender post 1, is connected mutually with fender post 1, and its development length is more than or equal to 400mm for the most beneficial; The other end run through enclose purlin 2 and the nut 6 arranged by end with enclose purlin 2 and be fastenedly connected, make to enclose purlin 2 and fender post 1 is connected as a single entity, jointly bear the horizontal shear force from skewed horizontal load steel pipe 4, increase its steadiness.
Learn through repeatedly calculating and testing, when the dowel 5 on each fender post 1 arranges 9 by three row's three row uniform intervals, and the spacing in vertical direction or horizontal direction between adjacent two dowels 5 is when being 150mm, the shearing force that can bear is maximum, and foundation pit supporting construction is the most firm.
