Description
Technical field
This utility model relates to building trade, particularly to foundation pit supporting construction.
Background technology
At present, the commonly used steel wale of deep foundation pit supporting structure waist rail, but being in the architectural engineering of northern area in engineering, winter temperature is relatively low, and the deep 22m of this Deep Foundation Pit, geological conditions contains a large amount of clay parting, owing to the clay property of water-bearing and water-retaining property are relatively big, temperature is the most too low, frost heave easily occurs, produce soil expansion, easily affect the stability of foundation pit supporting construction according to steel wale.
Summary of the invention
The utility model proposes reinforced concrete waist rail structure, this utility model simple in construction, improve the construction quality of reinforced concrete waist rail, the good stability of foundation pit supporting construction, improves construction speed, reduces construction cost.
For achieving the above object, the technical solution adopted in the utility model is: a kind of reinforced concrete waist rail structure, including reinforcement cage skeleton and pour the concrete inside and outside reinforcement cage skeleton, described reinforcement cage skeleton is become with stirrup colligation by longitudinal reinforcement, longitudinal anti-splitting bar-mat reinforcement it is provided with in reinforcement cage skeleton, anti-splitting bar-mat reinforcement is connected with reinforcement cage skeleton colligation, lacing wire it is provided with in reinforcement cage skeleton, lacing wire horizontally set and being connected with longitudinal reinforcement and stirrup colligation, it is intervally distributed with reinforced steel on described reinforcement cage skeleton, one end of reinforced steel is connected with reinforcement cage skeleton colligation, the other end stretches out reinforcement cage skeleton.
Described stirrup is stirrup of remaining silent, and stirrup is longitudinally spaced distribution on reinforcement cage skeleton.
Described anti-splitting bar-mat reinforcement is through to be arranged in reinforcement cage skeleton.
Described anti-splitting bar-mat reinforcement has two-layer, and two-layer anti-splitting bar-mat reinforcement is spaced apart.
The layout pitch of described reinforced steel is 500mm-1000mm.
This utility model, by using reinforced concrete waist rail, increases the contact surface of waist rail and supporting construction, it is possible to preferably transmission supporting construction and anchor pole fulcrum power, thus increases the stability of supporting construction.Compared with prior art, there is simple in construction, the good stability of foundation pit supporting construction, improves construction speed, reduces the advantages such as construction cost, can be widely used in building trade.
Accompanying drawing explanation

Fig. 2 is use view of the present utility model.
In figure: 1-longitudinal reinforcement, 2-stirrup, 3-lacing wire, 4-ground floor anti-splitting bar-mat reinforcement, the 5-second layer anti-splitting bar-mat reinforcement, 6-concrete, 7-reinforced steel.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail.
Reinforced concrete waist rail structure as shown in Figure 1, including reinforcement cage skeleton and be cast in the concrete 6 inside and outside reinforcement cage skeleton, reinforcement cage skeleton is the steel reinforcement cage become with stirrup 2 colligation by longitudinal reinforcement 1, being provided with the anti-splitting bar-mat reinforcement that two-layer is longitudinal in reinforcement cage skeleton, two-layer anti-splitting bar-mat reinforcement is through to be arranged in reinforcement cage skeleton.Ground floor anti-splitting bar-mat reinforcement 4 and the second layer anti-splitting bar-mat reinforcement 5 are spaced apart, anti-splitting bar-mat reinforcement is connected with reinforcement cage skeleton colligation, lacing wire 3 it is provided with in reinforcement cage skeleton, lacing wire 3 horizontally set and being connected with longitudinal reinforcement 1 and stirrup 2 colligation, being intervally distributed with reinforced steel 7 on reinforcement cage skeleton, the reinforced steel 7 layout pitch on waist rail is 1000mm-3000mm.One end of reinforced steel 7 is connected with reinforcement cage skeleton colligation, and the other end stretches out reinforcement cage skeleton muscle main with support pile and is welded to connect, as shown in Figure 2.
Reinforced concrete waist rail construction method comprises the steps:
1. preparation: mechanical engagement labor cleaning ground before reinforced concrete waist rail construction, leveling.Cleaning support pile face simultaneously, carries out picking chisel with electric pick docking contacting surface concrete, gently pick out pile concrete fresh.
2. anchor cable construction: manually adjust anchor cable steel strand wires elevation angle, it is ensured that make it in same level.
3. anchor cable protection set construction: complete anchor cable steel strand wires are each passed through 6 points of PVC plastic pipes by constructing; pvc pipe is buried in the earth not less than 100mm near inter-pile soil side; in hole, side exposes outside template not less than 50mm; select pvc pipe neither to affect anchorage cable stretching, again anchor cable steel strand wires are served protective effect simultaneously.
4. reinforcement cage skeleton is installed: reinforcement cage skeleton uses in-situ precast steel reinforcement cage, and after reinforcement yard is by steel reinforcement cage colligation, direct integral installation, manually adjusts reinforcement location, makes the reinforcing bar up and down crossing steel strand wires draw close to centre.
5. waist rail is reinforced: for preventing steel reinforcement cage from shifting, arranges waist rail reinforced steel, arranges reinforced steel in support pile interplanar distance 2.6m, when installing precast reinforced cage, by the most firm with steel reinforcement cage longitudinal reinforcement colligation for reinforced steel.
6. waist rail mould construction: lay the layer of non-woven fabric bed die as waist rail under steel reinforcement cage.
7. waist rail side form construction: waist rail side template uses single side formwork, selects the plank sheathing that surfacing is smooth, bores aperture in the anchor cable steel strand wires position of plank sheathing, and quantity is identical with corresponding anchor cable steel strand wires quantity, and PVC sleeve pipe and anchor cable steel strand wires are through boring.
8. waist rail formwork reinforcement: waist rail side template longitudinal rib uses 50mm steel pipe, top, bottom respectively arrange a sleeper and support, wood supports through layout, during steel pipe oblique cutting buries, angle is consistent with waist rail side template angle is 15 °, steel pipe level interval 1m, it may be necessary to utilize steel strand wires colligation iron wire reinforcing template.
9. concreting.
