Description
Technical field
The utility model relates to a kind of positioning tools of reinforcing bar in constructing tunnel, and in particular to a kind of short abutment wall lining in tunnel
Build reserved steel bar fast assembling-disassembling positioning fixture.
Background technique
It with the fast development of domestic high-speed railway, greatly enhances, super long tunnel gradually increases, the short side wall lining reinforcing bar in tunnel is fixed
Position required precision is also higher and higher, thus proposes acid test to the applicability of positioning fixture.Positioning work general at present
The limitation due to itself is filled, installation and dismounting efficiency are lower, and field operation worker's degree of recognition is low, promotes and applies by force
Consequence be the positioning tool that a large amount of human and material resources of waste are produced be placed on scene as meet check it is dedicated, form in order to
It is used with positioning fixture, while affecting operating worker operating efficiency, field operation efficiency is had a greatly reduced quality.
Utility model content
The utility model improves a kind of short side wall lining reserved steel bar fast assembling-disassembling positioning fixture in tunnel, to improve tunnel
The construction efficiency and positioning accuracy of the short side wall lining reinforcing bar in road.
In order to solve the above technical problems, technical solution used by the utility model is：
A kind of short side wall lining reserved steel bar fast assembling-disassembling positioning fixture in tunnel, including multiple fast assembling-disassemblings disposed in parallel
Bracket；The fast assembling-disassembling bracket is the triangular structure being made of the mutually hinged cross bar in end, vertical bar and brace；The cross
Bar includes hinged first crossbar and second crossbar；The fast assembling-disassembling bracket is connected between corresponding vertex by locating rod,
Multiple locating apertures for cooperating with reinforcing bar are uniformly provided in locating rod.
According to above scheme, the brace includes hinged the first brace and the second brace.
Compared with prior art, the utility model has the beneficial effects that：It can essence by folding fast assembling-disassembling bracket
The construction and installation of the short side wall lining reinforcing bar in tunnel are really efficiently completed, the positioning fixture structure is simple, stabilized structure, operation letter
Just, efficiently convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of fast assembling-disassembling bracket in the utility model；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the structural schematic diagram (holding state) when the utility model is specifically used；
Fig. 4 is the structural schematic diagram (non-holding state) when the utility model is specifically used.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing, the paraphrase of each label in figure
For：1- locating rod, the first brace of 2-, the second brace of 3-, 4- vertical bar, 5- second crossbar, 6- first crossbar.
The utility model mainly consists of two parts：Fast assembling-disassembling bracket and locating rod 1.
Fast assembling-disassembling bracket is the triangular structure being made of the mutually hinged cross bar in end, vertical bar 4 and brace.Cross bar,
The steel plate that vertical bar 4 and brace are all made of 5mm thickness is processed into the fillet rod piece of 3cm wide, and is carried out hingedly using pin stick.
Cross bar includes first crossbar 6 and second crossbar 5, and the right end of first crossbar 6 and the left end of second crossbar 5 hingedly connect
It connects.Brace includes the first brace 2 and the second brace 3, the left end articulated connection of the right end of the first brace 2 and the second brace 3.It is i.e. fast
Speed dismounting bracket specific connection relationship be：The left end of first crossbar 6 and the left end of the first brace 2 are hinged, the right side of the first brace 2
End is hinged with the left end of the second brace 3, and the lower end of the right end and vertical bar 4 of the second brace 3 is hinged, and the upper end of vertical bar 4 is horizontal with second
The right end of bar 5 is hinged, and the left end of second crossbar 5 and the right end of first crossbar 6 are hinged.Cross bar and brace are set as folding hinge
Binding structure, convenient for precisely controlling the installation accuracy of lining cutting reinforcing bar.Specific processing dimension is as shown in Table 1：
Table one：The materials and specific size of each component of fast assembling-disassembling bracket
(in a welding manner) is connected by locating rod 1 between the corresponding vertex of fast assembling-disassembling bracket, that is, corresponds to triangle
Three vertex, be equipped with three locating rods 1 parallel to each other altogether, just open up one in locating rod 1 at interval of 20cm and be used for and steel
The locating aperture of muscle cooperation.Locating rod 1 is made of the ∠ 4# angle steel of wall thickness 3mm, and the length of single locating rod 1 is 6m, positioning
The size of opening and reinforcing bar it is in the same size.The positioning fixture of complete set includes three locating rods 1 and seven fast assembling-disassembling branch
Frame.
The utility model in specific application, operates as follows：
The first step：6m sections of inverted arch longitudinal direction outer arc reinforcing bar, outer arc reinforcing bar longitudinal pitch 20cm are installed；
Second step：6m sections of inverted arch longitudinal direction inner arc reinforcing bar, inner arc reinforcing bar longitudinal pitch 20cm are installed；
Third step：The short side wall lining reserved steel bar fast assembling-disassembling positioning fixture of 6m long tunnel is installed, reinforcing bar is adjusted to fixed
In the locating aperture of position bar 1, lifting/pressing fast assembling-disassembling bracket to first crossbar 6 and the same straight line of second crossbar 5 (while first
Brace 2 and the second brace 3 also same straight line) installation positioning fixture is completed afterwards；
4th step：Inverted arch overlay film and casting concrete are installed, health waits for by force；
5th step：By pin stick pressure/drawing rapid dismounting apparatus, make first crossbar 6 and second crossbar 5 and the first brace 2
With the second brace 3 not in same straight line, so that positioning fixture is separated with reserved steel bar, positioning fixture is removed.
6th step：The installation of next circulation is carried out by the step of first step~five step.
This practicability is suitable for the positioning of the short side wall lining reserved steel bar longitudinal pitch of Railway Tunnel and lateral position
Short side wall lining reserved steel bar positioning accuracy not only can be improved by fast assembling-disassembling bracket in operation, the steel bar positioning fixture, and
And short side wall lining reserved steel bar location efficiency can be improved, there is great promotion prospect.
