Abstract
Two lining bar reinforcement positioning devices are related to a kind of device positioned to two lined steel muscle when building tunnel.Deviation, the problem of steel bar positioning fixture can not be reused are located to ring cage bar using circumferential reinforcement positioning fixture in pre-buried two lining reinforcement constructions at present and designed.It includes riser and transverse slat, it is connected at the top of the rear end of transverse slat and riser, described riser bottom uniformly offers several hollow bolts and passes through hole, also include passing through hole number identical hollow bolt with hollow bolt, each hollow bolt is inserted respectively into each hollow bolt and passed through in hole, and by the way that hollow bolt is fixed positioned at the clamp nut of riser front and rear sides, a spiral is designed with each hollow bolt, described transverse slat front portion uniformly offers several ring cage bar locating slots.Advantage is accurate positioning, can be repeatedly used.
Description
Technical field：
The utility model is related to a kind of device positioned to two lined steel muscle when building tunnel.
Background technology：
Tunnel double-lining is the important step in supporting and protecting system of tunnel, and the lining of armored concrete two and preliminary bracing carry enclose together
The stress load of rock deformation.Generally positioned at present in pre-buried two lining reinforcement constructions using circumferential reinforcement positioning fixture, its
It is disadvantageous in that and deviation is located to ring cage bar, it is inaccurate, construction quality is influenceed, circumferential reinforcement positioning fixture can not in addition
Reuse, cause to waste.
The content of the invention：
Technical problem to be solved in the utility model is to provide a kind of accurate positioning, and reused two lined steels muscle is determined
Position device.
What above-mentioned purpose was realized in：It includes being connected at the top of riser and transverse slat, the rear end of transverse slat and riser,
That is transverse slat and riser is vertically arranged, and described riser bottom uniformly offers several hollow bolts by hole, in addition to
Hollow bolt is by hole number identical hollow bolt, and each hollow bolt is inserted respectively into each hollow bolt by hole, and leads to
Hollow bolt is fixed the clamp nut crossed positioned at riser front and rear sides, and a screw thread is designed with each hollow bolt
Reinforcing bar, described transverse slat front portion uniformly offers several ring cage bar locating slots.
The utility model has the advantages that：At the beginning of the spiral end in each hollow bolt is fixed on into tunnel side wall when using
On branch face, ring cage bar is positioned by the ring cage bar locating slot on transverse slat, after construction terminates, spiral separated
The present apparatus can be taken out.Its accurate positioning, zero deflection, it is ensured that construction quality, can be repeatedly used.
Brief description of the drawings：
Fig. 1 is main structure diagram of the present utility model；
Fig. 2 is overlooking the structure diagram of the present utility model.
Embodiment：
Referring to Figures 1 and 2, it includes being connected at the top of riser 1 and transverse slat 2, the rear end of transverse slat and riser, i.e. transverse slat
Be vertically arranged with riser, described riser bottom uniformly offers several hollow bolts by hole, in addition to middle spare anchor
Bar is by hole number identical hollow bolt 3, and each hollow bolt is inserted respectively into each hollow bolt by hole, and by positioned at
Hollow bolt is fixed the clamp nut 4 of riser front and rear sides, and a spiral 5 is designed with each hollow bolt,
Described transverse slat front portion uniformly offers several ring cage bar locating slots 6.
