Description
Technical field
The utility model relates to constructing tunnel apparatus technical field, particularly relates to a kind of tunnel double-lining steel bar positioning fixture.
Background technology
Tunnel double-lining is a ring important in supporting and protecting system of tunnel, particularly execute the pre-buried two lined steel muscle of man-hour requirement at weak surrounding rock location inverted arch, steel concrete two serves as a contrast as last safety curtain, both can carry the stress load of surrouding rock deformation together with preliminary bracing, construction safety and operation security can have been ensured as one last barrier again.But be often designed to steel concrete in the construction of weak surrounding rock location steel tunnel double-lining, traditional embedded bar construction does not control rebar spacing and array pitch by rebar clips, cause rebar spacing and array pitch after concreting uneven, after finally causing two lining concrete constructions, reinforcing steel bar bear is uneven, and two lining structure surfaces occur that crack affects structure stress in various degree.The colligation of this manual operation reinforcing bar is installed random strong, the longitudinal pitch of two lined steel muscle and the interlamellar spacing of double steel bar are difficult to keep consistency and accuracy, can cause that construction quality is undesirable, long construction period, costly, the problems such as intractability is large of doing over again.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of structure tunnel double-lining steel bar positioning fixture simple, easy to operate, with low cost, can ensure tunnel double-lining reinforcing bar positioning precision and increase work efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of tunnel double-lining steel bar positioning fixture, comprise two location-plates and some connecting rods, described location-plate is symmetricly set on connecting rod two ends, draw-in groove is laid with and adjacent card separation is consistent with reserved steel bar spacing outside described location-plate, adjacent card separation can carry out processing adjustment according to the reserved steel bar spacing difference of layout design, and length of connecting rod and reserved steel bar array pitch match.
Preferably, described connecting rod two ends are provided with screw thread, and described connecting rod two ends are fixed on location-plate by nut, are adjusted the array pitch of reserved steel bar by location-plate in the permanent position at connecting rod two ends.
Preferably, described location-plate is angle steel, and described two angle steel are opposing is arranged on connecting rod two ends, and described draw-in groove is located at outside angle steel horizontal plane, and described connecting rod is fixed on angle steel vertical plane.
Preferably, described interlinking lever end and angle steel vertical plane are fixed with two nuts and two nuts are separately positioned on angle steel vertical plane both sides respectively.
The beneficial effect adopting technique scheme to produce is: utilize location-plate to be stuck in equally spaced draw-in groove by reinforcing bar and position, require two location-plates to be fixed according to the array pitch of reinforcing bar with connecting rod again, control well after the longitudinal pitch of two lining reserved steel bars and array pitch, concrete casting and constructing can be carried out, after concrete setting, location-plate can unload by the nut unclamping connecting rod two ends, can also reuse.The utility model has structure advantage simple, easy to operate, with low cost, and make and simply can reuse, change tradition pre-buried two lining construction spacing and array pitch uneven, the variety of problems of generation is arbitrarily set, through practical proof, the utility model has thoroughly solved the control problem of the pre-buried two lining rebar spacings in tunnel and array pitch, also improve the accuracy of tunnel double-lining embedded bar position simultaneously, decrease because reinforcing bar arbitrarily arranges the post-processed expense caused, save extra cost, and work efficiency is significantly improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the left view of Fig. 1;
In figure: 1-location-plate, 2-connecting rod, 3-draw-in groove, 4-nut, plane on 11-angle steel, 12-angle steel vertical plane.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of tunnel double-lining steel bar positioning fixture as shown in Figure 1, 2, comprise two location-plates 1 and some connecting rods 2, described location-plate 1 is symmetricly set on connecting rod 2 two ends, draw-in groove 3 is laid with and adjacent draw-in groove 3 spacing is consistent with reserved steel bar spacing outside described location-plate 1, adjacent draw-in groove 3 spacing can process adjustment voluntarily according to the rebar spacing Different field of layout design, connecting rod 2 length and reserved steel bar array pitch match, and draw-in groove 3 and connecting rod 2 quantity are determined according to actual needs.
Conveniently adjust the array pitch of two row's reserved steel bars, process screw thread at connecting rod 2 two ends, described connecting rod two ends are fixed on location-plate 1 by nut 4.The position at connecting rod 2 two ends of location-plate 1 can be adjusted according to Design Requirement Drawing, thus the array pitch of adjustment reinforcing bar.
Conveniently buy and make material, make and simply can reuse, described location-plate 1 can select angle steel, and be arranged on connecting rod 2 two ends by opposing for two angle steel, described draw-in groove 3 is arranged on outside angle steel horizontal plane 11, and described connecting rod 2 is fixed on angle steel vertical plane 12.Utilize and process that the steel plate of U-type groove is uniform to be welded on outside angle steel horizontal plane 11 as draw-in groove 3; Also directly draw-in groove 3 can be provided as at angle steel horizontal plane 11 outer ledge fluting; Or adopt the reinforcing bar leftover bits and pieces of site construction to be welded on angle steel horizontal plane 11 outer ledge and form draw-in groove 3, segment reinforcing bar is received the lateral surface of angle steel horizontal plane 11 according to the rebar spacing horizontal welding of reserved steel bar size and drawing requirement.Angle steel length can be determined according to every plate inverted arch length.
Described connecting rod 2 end and angle steel vertical plane 12 fix with two nuts 4 respectively and two nuts 4 are separately positioned on angle steel vertical plane 12 both sides, and such connecting rod 2 is fixing more firm with angle steel, avoids angle steel on connecting rod from inward at both ends generation translation.
Concrete use procedure is as follows: reinforcing bar is stuck in equally spaced draw-in groove 3 and positions by the location-plate 1 utilizing angle steel to make, relend and help connecting rod 2 to require two angle steel nuts 4 to be fixed according to the array pitch of reinforcing bar, make two lining rebar spacings, array pitch one-time positioning, there will not be deviation, thus ensure the reinforcement construction quality of two linings; Control well after the longitudinal pitch of two lining reserved steel bars and array pitch, can carry out concrete casting and constructing, after concrete setting, angle steel can unload by the nut 4 unclamping connecting rod two ends, and the angle steel unloaded down and connecting rod 2 can also reuse.Relative to the method for other traditional positioning bars, precision is high, and efficiency is high, one-shot forming.
In sum, it is simple that the utility model has structure, easy to operate, advantage with low cost, and make and simply can reuse, change tradition pre-buried two lining construction spacing and array pitch uneven, the variety of problems of generation is arbitrarily set, through practical proof, the utility model has thoroughly solved the control problem of the pre-buried two lining rebar spacings in tunnel and array pitch, also improve the accuracy of tunnel double-lining embedded bar position simultaneously, decrease because reinforcing bar arbitrarily arranges the post-processed expense caused, save extra cost, and work efficiency is significantly improved.The utility model is suitable for the location of reinforcing bar in all tunnel double-lining reinforced concrete constructions.
