Abstract
A kind of soil anchor list anchor expansion self-locking device, including fixed pad, propulsion cap, expansion anchor fluke, bar axis, connecting rod, fix pad and are equipped with a tapped through hole；Propulsion cap is taper barrel；It expands anchor fluke and is equipped with bar axis, two expansion anchor flukes are hinged on the both ends of connecting rod by bar axis, are equipped with through-hole in the center of connecting rod；In use, anchor bar/anchor cable passes through connecting rod and cap is promoted to be spirally connected with fixed pad, fixed pad promotes cap, expansion anchor fluke to be sequentially placed into the anchor hole of foundation pit slight slope, and cap smaller diameter end is promoted inwardly to place, and one end of two expansion anchor flukes, which is placed in, to be promoted in cap.The present invention is simple to operation, flexible and convenient to use, low in cost.Anchor bar/anchor cable generates pulling force to propulsion cap by fixed pad, and by promoting cap to generate the expansionary force of a reverse propulsion to expansion anchor fluke, so that two expansion anchor fluke free-extensions, generate the reversal of stress effect for the more drawing the more tight, the safety coefficient for increasing anchoring better meets the security and stability of soil nail wall entirety.
Description
Technical field
The present invention relates to construction Base hole supporting technology field more particularly to a kind of foundation pit supporting construction soil nail wall list anchors
Expand self-locking device.
Background technique
With the progress of economic fast development and building technology, in building engineering field since the depth of underground engineering increases
Greatly, the underground structure of many buildings needs to carry out the supporting on periphery cubic metre of earth when constructing underground foundation and space segment, to guarantee
There are enough spaces to guarantee the safety condition of operating personnel, the safety measure of foundation pit slope protection is particularly important.
Inventor adheres to that the relevant industries are abundant for many years designs and develops and the experience of practice of construction, for existing construction
And function is researched and developed, and a kind of native anchor expansion self-locking device is provided, to reach safer in supporting foundation pit slope protection
Reliably, simple and practical purpose.
Summary of the invention
The object of the present invention is to provide a kind of native anchor list anchors to expand self-locking device, and the present apparatus is suitable for single anchor pole or anchor cable
It uses, anchor pole or anchor cable is used cooperatively with the present apparatus, the present apparatus is driven by the tensile stress generated in carrying out drawing process
Pulling force is reached to promote and finally again concentrates on strength on expansion anchor fluke at cap it is made to generate opposition by the fixed pad in inside, is led
Causing two anchor fluke expansions of the present apparatus, more anchor is tighter in the soil body, good tensile stress is formed, to guarantee excavation slope soil anchor rod
It is more stable, increase the coefficient of stability of its soil nail wall itself.
To achieve the above object, the present invention is implemented with the following technical solutions:
A kind of soil anchor list anchor expansion self-locking device, including fixed pad, propulsion cap, expansion anchor fluke, bar axis, connecting rod, it is described solid
Fixed pad is equipped with a tapped through hole；The propulsion cap is taper barrel；The expansion anchor fluke is equipped with bar axis, two expansion anchors
Pawl is oppositely arranged, and two expansion anchor flukes are hinged on the both ends of connecting rod by bar axis, is equipped with through-hole in the center of the connecting rod；
In use, soil anchor bolt or native anchor cable pass through connecting rod and promote cap and be spirally connected with the tapped through hole on fixed pad, fixed pad is promoted
Cap, expansion anchor fluke are sequentially placed into the anchor hole of foundation pit slight slope, and the smaller diameter end for promoting cap is inwardly placed, two expansion anchors
One end of pawl, which is placed in, to be promoted in cap.
It is circular arc tubular that the expansion anchor fluke, which is by steel plate or iron plate curling, is up and down tip setting.
Compared with prior art, the beneficial effects of the present invention are:
1) complete equipment is simple to operation, flexible and convenient to use, low in cost.
2) anchor bar/anchor cable is connected with fixed pad, during being stretched, is formed and is drawn to propulsion cap by fixed pad
Power, promote the pulling force effect of cap on expansion anchor fluke, so that free-extension after two expansion anchor fluke stress, generates and the more draws the more tight
Reversal of stress effect largely increases the safety coefficient of anchoring, better meets the security and stability of soil nail wall entirety.
Detailed description of the invention
Fig. 1 is a kind of native anchor list anchor expansion self-locking device main view of the present invention.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3 is the B-B view of Fig. 1.
Fig. 4 is the C-C view of Fig. 1.
In figure: the fixed pad of 1-, 2- promote cap, 3- tapped through hole, 4- bar axis, 5- connecting rod, 6- to expand anchor fluke, 7- through-hole.
Specific embodiment
The present invention is described in detail below, it should be noted that implementation of the invention embodiment party not limited to the following
Formula.
As Figure 1-Figure 4, a kind of native anchor list anchor expands self-locking device, including fixed pad 1, promote cap 2, expansion anchor fluke 6,
Bar axis 4, connecting rod 5, the fixed pad 1 are equipped with a tapped through hole 3；The propulsion cap 2 is taper barrel；The expansion anchor fluke
6 are equipped with bar axis 4, and two expansion anchor flukes 6 are oppositely arranged, and two expansion anchor flukes 6 are hinged on the both ends of connecting rod 5 by bar axis 4,
The center of the connecting rod 5 is equipped with through-hole 7；In use, soil anchor bolt or native anchor cable pass through connecting rod 5 and propulsion cap 2 and with fixation
Tapped through hole 3 on pad 1 is spirally connected, and fixed pad 1 promotes cap 2, expansion anchor fluke 6 to be sequentially placed into the anchor hole of foundation pit slight slope, described
The smaller diameter end of cap 2 is promoted inwardly to place, one end of two expansion anchor flukes 6, which is placed in, to be promoted in cap 2.
It is circular arc tubular that the expansion anchor fluke 6, which is by steel plate or iron plate curling, is up and down tip setting.
Steel plate/iron plate for making expansion anchor fluke 6 is quadrangle, and the quadrangle is using one of diagonal line as axis
Symmetrically, steel plate/iron plate is curled into the tubular of semi arch using the diagonal line as the axis direction of cylinder when curling.
Bar axis 4 is laterally worn and is connect on expansion anchor fluke 6, expansion anchor fluke 6 is hinged on to the both ends of connecting rod 5 by bar axis 4, when
When one end of expansion anchor fluke 6 is inwardly overturn, the other end expands outwardly naturally.The center of connecting rod 5 be equipped with through-hole 7 be used for across
Anchor pole or anchor cable.
In the anchor hole for the foundation pit slight slope that soil anchor bolt/soil anchor cable is fixed by conventional methods, installs and fix when whole device
After good, during soil anchor bolt/soil anchor cable is stretched, soil anchor bolt/soil anchor cable can be to fixed 1 one pulling force of pad, the pulling force
Push out promote cap 2, due to promote cap 2 be taper barrel, make expand anchor fluke 6 to promote cap 2 inside slide into during
Expansion is flipped outward, leading to it, more anchor is tighter in the soil body, produces the reversal of stress for the more drawing the more tight.
The present invention comprehensively updates traditional soil-nail wall support device, adds completely new anchoring and expands self-locking dress
It sets, increase soil anchor bolt/rope anchor which can be bigger draws reaction stress, draws its anchor tie Suo Yue tighter, preferably
Guarantee the stabilization of soil nail wall, increases the safety of slight slope protection.
