Description
Technical field
The utility model is related to architectural engineering pit supporting apparatus field, more particularly to a kind of pattern foundation pit supporting structure soil nailing.
Background technology
Pattern foundation pit supporting structure is to ensure the safety of Underground Construction and foundation ditch surrounding enviroment, to foundation pit side-wall and surrounding enviroment
Supporting and retaining system, reinforcing and the safeguard measure of use.
Application of the soil-nail wall support in pattern foundation pit supporting structure is very universal, and technology is also quite ripe.Soil nail wall is a kind of in situ
Soil body reinforcement technology.It is configured to be arranged on reinforcement rod member (i.e. soil nailing or anchor pole) and its surrounding soil secure bond in slopes
The complex of formation, and the supporting construction of similar Form Gravity Breast Wall that surface layer is constituted.
Soil-nail wall support construction procedure is as follows：1st, slope excavating；2nd, manual amendment side slope is domatic；3rd, line setting, really
The position of fixed each soil nailing and mark；4th, manual pore-forming；5th, soil nailing cage bar is made（The body of rod）And place in muscle hole, the outer end of cage bar
End sets reserved section to be used to weld with horizontal beading；6th, to aerial slip casting；7th, linked network；8th, jetting cement.
But in the prior art, as shown in figure 1, most using single " L " type construction, bending during the design of the end of the soil nailing body of rod 1
Welded with horizontal beading 2 in portion 12.This way is present with drawback：
Reinforcing bar has infringement when cold bend(ing) is into " L " type to reinforcing bar, and after " L " type crotch is welded with horizontal beading 2, soil nailing is in tension
Force part is the flex point weld 11 of " L " type crotch first during power, is extended back successively, and the position beyond overlapping part can not
Equably while stress, can cause " L " type crotch to be torn with the horizontal weld of beading 2, cause the accident.
Utility model content
The purpose of this utility model is to provide a kind of pattern foundation pit supporting structure soil nailing, can improve soil nailing and horizontal beading welding position
Firmness.

Beading can improve the firmness of soil nailing and horizontal beading welding position directly through welding together after neck with the body of rod；It is existing
Have in technology, when carrying out single-sided welding, the hook length of general L-type is five times of shank diameter, causes the wave of reinforcing bar main material
Take, the utility model direct to the body of rod need not be bent, and reduce the waste of reinforcing bar main material.
Preferably, the length of first brace rod and the second brace rod is identical.
By using above-mentioned technical proposal, in the prior art, the body of rod is bent into l-shaped, not only waste of materials also wastes people
The length of power, first support bar and second support bar is identical, then can disposably make more first support bar and second
Strut, operation is easy, saves manpower.
Preferably, the length of the first brace rod is two to three times of shank diameter.
By using above-mentioned technical proposal, it is ensured that while the body of rod is with horizontal beading weld firmness, also reduce
The consumption of first brace rod and the second brace rod, has saved material.
Preferably, being welded with pernetti on the body of rod.
By using above-mentioned technical proposal, if the body of rod stretches into Kong Zhonghou, periphery and the hole of the body of rod fit, then rear
During continuous slip casting, the position that the body of rod fits with hole can be because the concrete injected be less and insecure, and the setting of pernetti can be with
The body of rod is supported so that gap is formed between the body of rod and hole.
Preferably, the pernetti includes multigroup support bar perpendicular to the body of rod, every group of support bar is included along body of rod axle
To arrangement and the first pole and the second pole of equal length.
By using above-mentioned technical proposal, after the body of rod is stretched into hole, end and the hole inwall of support bar fit, can be by
Separate, while being formed with gap between adjacent support bar, follow-up slip casting will not be caused between the body of rod and the inwall in hole
Influence；The equal length of first pole and the second pole, then can cause the body of rod to be located at the center in hole as far as possible.
Preferably, the pernetti includes the support that multigroup centering is welded.
By using above-mentioned technical proposal, the support that centering is set can be prevented in body of rod offset bore to a certain extent
The heart so that the body of rod is as equal as possible with the distance between hole wall, contributes to the progress of follow-up slip casting work.
Preferably, the section of the support is isosceles trapezoid.
By using above-mentioned technical proposal, the contact area of support and hole wall can be increased, body of rod axle is further increased
The Aligning degree at Xian Yukong centers.
Preferably, the distance between described adjacent pernetti is 1m.
By using above-mentioned technical proposal, while effectively can realizing pernetti, pernetti and the body of rod can be reduced again
Weld.
In summary, the utility model has the advantages that：It is formed between first brace rod and the second brace rod
Neck, improves the firmness of the body of rod and horizontal beading weld；Save material.
