Description
Technical field:
The present invention relates to the construction technologies positioned to tunnel double-lining reinforcing bar.
Background technique:
It is all that two lined steel muscle are positioned by way of manual measurement at present in constructing tunnel, this positioning side
Formula cause the layer between internal layer reinforcing bar and outer reinforcement away from and each layer reinforcing bar between spacing accuracy it is low, in addition casting concrete
Shi Yi causes single steel bar to shift steel bars, influences construction quality.
Summary of the invention:
Technical problem to be solved by the invention is to provide the layer between a kind of certifiable internal layer reinforcing bar and outer reinforcement away from
And the spacing uniformity between each layer reinforcing bar, when being poured concrete reinforcing bar will not shift to tunnel double-lining reinforcing bar positioning
Construction technology.
Above-mentioned purpose is achieved in that the position between the internal layer circumferential reinforcement and outer layer circumferential reinforcement of two lined steel muscle
Place sets elongated layer away from positioning angle steel, and layer is bolted on tunnel wall away from the both ends of positioning angle steel, then sets two and lead to
Long channel steel, this two channel steels are respectively internal layer circumferential reinforcement limit channel steel and outer layer circumferential reinforcement limit channel steel, and two
All be provided with several circumferential reinforcement limiting slots by the spacing of design on channel steel, by the limit of internal layer circumferential reinforcement with channel steel be located at layer away from
The top of angle steel is positioned, and makes steel hoop limiting slot on internal layer circumferential reinforcement limit channel steel towards internal layer steel hoop,
Each steel hoop limiting slot all from layer away from positioning angle steel in stretch out；The limit of outer layer circumferential reinforcement is also provided in layer away from positioning with channel steel
The top of angle steel, and make the steel hoop limiting slot on outer layer circumferential reinforcement limit channel steel towards outer layer circumferential reinforcement, each ring
Shape reinforcing bar limiting slot is all stretched out from layer away from positioning angle steel；Two channel steel positions install rear both ends by bolt and layer away from orientation angle
Steel is fixed together；
Each circumferential reinforcement of internal layer is stuck in the circumferential reinforcement limiting slot of internal layer circumferential reinforcement limit channel steel, and
And all internal layer circumferential reinforcements is made all to be tightly attached to layer away from positioning angle steel, each steel hoop of outer layer is stuck in outer layer ring
Into the circumferential reinforcement limiting slot of reinforcing bar limit channel steel, and all outer layer circumferential reinforcements is made all to be tightly attached to layer away from orientation angle
On steel, the positioning to internal layer circumferential reinforcement and outer layer circumferential reinforcement is thereby realized, then reinforcing bar is bound, casting is mixed
Solidifying soil, unloads two channel steels after concrete initial set, and layer is cast in concrete away from positioning angle steel.
The invention has the advantages that due to setting layer between internal layer circumferential reinforcement and outer layer circumferential reinforcement away from positioning angle steel, and
And internal layer circumferential reinforcement and outer layer circumferential reinforcement are limited by two channel steels, it can guarantee internal layer circumferential reinforcement and outer in this way
The layer of layer circumferential reinforcement is away from accurate with spacing, and when being poured concrete, reinforcing bar is not shifted, and ensure that construction quality.
Specific embodiment:
Elongated layer is set away from orientation angle at position between the internal layer circumferential reinforcement and outer layer circumferential reinforcement of two lined steel muscle
Steel, layer is bolted on tunnel wall away from the both ends of positioning angle steel, then sets two elongated channel steels, this two channel steels point
Not Wei internal layer circumferential reinforcement limit channel steel and outer layer circumferential reinforcement limit channel steel, all opened by the spacing of design on two channel steels
There are several circumferential reinforcement limiting slots, the limit of internal layer circumferential reinforcement is located at top of the layer away from positioning angle steel with channel steel, and make interior
Steel hoop limiting slot on layer circumferential reinforcement limit channel steel is towards internal layer steel hoop, and each steel hoop limiting slot is all from layer
It is stretched out away from positioning in angle steel；The limit of outer layer circumferential reinforcement is also provided in top of the layer away from positioning angle steel with channel steel, and makes outer layer ring
Steel hoop limiting slot on reinforcing bar limit channel steel is towards outer layer circumferential reinforcement, and each steel hoop limiting slot is all from layer away from fixed
Parallactic angle steel stretches out；Two channel steel positions install rear both ends and are fixed together by bolt and layer away from positioning angle steel；
Each circumferential reinforcement of internal layer is stuck in the circumferential reinforcement limiting slot of internal layer circumferential reinforcement limit channel steel, and
And all internal layer circumferential reinforcements is made all to be tightly attached to layer away from positioning angle steel, each steel hoop of outer layer is stuck in outer layer ring
Into the circumferential reinforcement limiting slot of reinforcing bar limit channel steel, and all outer layer circumferential reinforcements is made all to be tightly attached to layer away from orientation angle
On steel, the positioning to internal layer circumferential reinforcement and outer layer circumferential reinforcement is thereby realized, then reinforcing bar is bound, casting is mixed
Solidifying soil, unloads two channel steels after concrete initial set, and layer is cast in concrete away from positioning angle steel.
