Description
Technical Field
The utility model belongs to the technical field of the tunnel construction technique and specifically relates to a reinforcing bar net component, strut reinforcing bar net and be used for supporting reinforcing bar net of tunnel are related to.
Background
In the construction process of the tunnel, concrete support by hanging a reinforcing mesh is a common primary support measure, particularly the tunnel is excavated in a region with poor geology, and the reinforcing mesh is generally required to be hung quickly after primary concrete spraying after excavation so as to fix unstable rock blocks in the tunnel and prevent casualty accidents caused by the falling of the blocks.
The existing technology for hanging the reinforcing mesh in the tunnel generally adopts a method for manually binding reinforcing steel bars in the tunnel, so that the time consumption is long, and no support measures are taken when the reinforcing steel bars of the mesh hanging are bound in the tunnel, so that the danger of constructors is high. In addition, the phenomenon of binding omission is easy to occur in the binding process of the net hanging reinforcing steel bars, and the quality of the bound net hanging reinforcing steel bars in the holes is difficult to control.
Therefore, it is desirable to provide a mesh reinforcement member, a supporting mesh reinforcement and a supporting mesh reinforcement for a tunnel that solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a reinforcing bar net component that can assemble fast, strut reinforcing bar net and be used for the supporting reinforcing bar net of tunnel.
The technical scheme of the utility model is that: the reinforcing mesh component comprises a main rib and a plurality of connecting ribs vertically arranged in the length direction of the main rib at intervals, wherein the tail ends of the connecting ribs far away from the main rib are in a hook shape, and the hook shape is bent towards the main rib.
Preferably, the hook-shaped portion is located on the same side or opposite side of the connecting rib as the main rib.
Preferably, the hook shape is an arc or square structure.
Preferably, the main ribs and the connecting ribs are steel bars with phi 6.0mm, and the connecting ribs are vertically welded on the main ribs at intervals of 200 mm.
The utility model also provides a strut reinforcing bar net, including a plurality of formation of meeting end to end by foretell reinforcing bar net component.
Preferably, the end-to-end connection is that the hook shape of the connecting bar of one mesh reinforcement member hooks the main bar of the other mesh reinforcement member.
The utility model also provides a supporting reinforcing mesh for the tunnel, which comprises a plurality of reinforcing mesh components which are connected end to end; the main rib is an urban door opening type structure and is attached to the inner wall of the tunnel.
Preferably, the end-to-end connection is that the hook shape of the connecting bar of one mesh reinforcement member hooks the main bar of the other mesh reinforcement member.
Compared with the prior art, the beneficial effects of the utility model are that:
the steel bar member has a simple structure, can be processed outside a hole in batches, and ensures the quality of a steel bar mesh;
secondly, after the tunnel is excavated, the reinforcing mesh can be laid quickly, so that the construction progress of the tunnel is accelerated, and the stability of surrounding rocks of the tunnel is facilitated;
thirdly, the provided quick support reinforcing mesh is simple in structure and does not need special equipment for processing;
and fourthly, the reinforcing mesh members are processed outside the holes in batches, welding or binding processes are not needed in the assembling process in the holes, and the construction risk of constructors in the holes is reduced.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" used herein refer to the directions of the drawings, and do not limit the structure of the drawings.
As shown in fig. 1 and 2, the mesh reinforcement member provided by the present invention comprises a main bar 1 and a plurality of connecting bars 2 vertically spaced from each other in the length direction of the main bar 1. The main reinforcement 1 and the connecting reinforcement 2 are steel bars with phi 6.0mm, and the connecting reinforcement is vertically welded on the main reinforcement 1 at a distance of 200 mm.
The tail end of the connecting rib 2, which is far away from the main rib 1, is in a hook shape, the hook shape is arranged in a bending mode towards the main rib, the hook shape is in an arc or square structure, and the hook shape and the main rib 1 are located on the same side or the opposite side of the connecting rib 2.
The utility model provides a support reinforcing bar net then has a plurality ofly one in the reinforcing bar net component the angle hook shape of the splice bar 2 of reinforcing bar net component catches on the main muscle 1 of another reinforcing bar net component, end to end forms.
As shown in fig. 3, the utility model provides a strut reinforcing bar net for tunnel, its string net reinforcing bar component process into tunnel excavation section shape outside the hole, in this embodiment, hangs the net reinforcing bar component and processes into city door opening type. After the tunnel is excavated, a certain number of processed and formed tunnel reinforcing mesh components are transported into the tunnel according to the construction length of the tunnel, when the reinforcing mesh is laid in the tunnel, the connecting rib 2 hook in the former reinforcing mesh component hooks the main rib 1 in the latter reinforcing mesh component, and the supporting reinforcing mesh does not need welding or binding operation when laid in the tunnel, so that the mesh-hanging reinforcing construction in the tunnel can be quickly realized.
