The invention discloses a rapid dismounting and positioning fixture for a tunnel short side wall lining reserved steel bar, which comprises a plurality of rapid dismounting and mounting brackets which are arranged in parallel; the quick dismounting support is a triangular structure formed by a cross rod, a vertical rod and an inclined rod, wherein the ends of the cross rod, the vertical rod and the inclined rod are hinged with each other; the cross bars comprise a first cross bar and a second cross bar which are hinged; the vertexes corresponding to the quick assembly and disassembly support are connected through the positioning rod, and a plurality of positioning openings used for being matched with the steel bars are evenly formed in the positioning rod. The positioning fixture has the advantages that the construction and installation of the lining reinforcing steel bars of the short side wall of the tunnel can be accurately and efficiently finished through the foldable quick dismounting bracket, and the positioning fixture has a simple structure, a stable structure, simplicity and convenience in operation, high efficiency and convenience.
Description
Technical field
The present invention relates to a kind of positioning tools of reinforcing bar in constructing tunnel, and in particular to pre- to a kind of short side wall lining in tunnel
Stay reinforcing bar fast assembling-disassembling positioning fixture.
Background technology
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
Dress is due to the limitation of itself, and installation and dismounting efficiency are relatively low, 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 special, 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.
Invention content
The present invention improves a kind of short side wall lining reserved steel bar fast assembling-disassembling positioning fixture in tunnel, short to improve tunnel
The construction efficiency and positioning accuracy of side wall lining reinforcing bar.
In order to solve the above technical problems, the technical solution adopted in the present invention 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
Holder；The fast assembling-disassembling holder is the triangular structure being made of the mutually hinged cross bar in end, montant and brace；The cross
Bar includes hinged first crossbar and second crossbar；The fast assembling-disassembling holder is connected between corresponding vertex by locating rod,
Multiple locating apertures for coordinating with reinforcing bar are uniformly provided in locating rod.
According to said program, the brace includes hinged the first brace and the second brace.
Compared with prior art, the beneficial effects of the invention are as follows：It can be accurate high by folding fast assembling-disassembling holder
The construction and installation of the short side wall lining reinforcing bar in tunnel are completed on effect ground, and the positioning fixture is simple in structure, and stabilized structure is easy to operate, high
It is convenient to imitate.
Description of the drawings
Fig. 1 is the structural schematic diagram of fast assembling-disassembling holder in the present invention；
Fig. 2 is the structural schematic diagram of the present invention；
Fig. 3 is the structural schematic diagram (holding state) when the present invention is specifically used；
Fig. 4 is the structural schematic diagram (non-holding state) when the present invention is specifically used.
Specific implementation mode
The specific implementation mode of the present invention is described further below in conjunction with the accompanying drawings, each label is interpreted as in figure：1-
Locating rod, the first braces of 2-, the second braces of 3-, 4- montants, 5- second crossbars, 6- first crossbars.
The present invention mainly consists of two parts：Fast assembling-disassembling holder and locating rod 1.
Fast assembling-disassembling holder is the triangular structure being made of the mutually hinged cross bar in end, montant 4 and brace.Cross bar,
The steel plate that montant 4 and brace are all made of 5mm thickness is processed into the fillet rod piece of 3cm wide, and is hinged 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 holder specific connection relation be：The left end of the left end of first crossbar 6 and the first brace 2 is hinged, the right side of the first brace 2
End and the left end of the second brace 3 are hinged, and the right end of the second brace 3 is hinged with the lower end of montant 4, and the upper end of montant 4 is horizontal with second
The right end of bar 5 is hinged, and the left end of second crossbar 5 is hinged with the right end of first crossbar 6.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 holder
(in a welding manner) is connected by locating rod 1 between the corresponding vertex of fast assembling-disassembling holder, 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 present invention in specific application, operates as follows：
The first step：Longitudinal direction 6m sections of outer arc reinforcing bar of inverted arch, outer arc reinforcing bar longitudinal pitch 20cm are installed；
Second step：Longitudinal direction 6m sections of inner arc reinforcing bar of inverted arch, inner arc reinforcing bar longitudinal pitch 20cm are installed；
Third walks：The short side wall lining reserved steel bar fast assembling-disassembling positioning fixture of 6m long tunnels is installed, reinforcing bar is adjusted to fixed
In the locating aperture of position bar 1,5 same straight line of lifting/pressing fast assembling-disassembling holder to first crossbar 6 and second crossbar (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 detached with reserved steel bar, removes positioning fixture.
6th step：The installation of next cycle 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
Operation, the steel bar positioning fixture can not only improve short side wall lining reserved steel bar positioning accuracy by fast assembling-disassembling holder, and
And short side wall lining reserved steel bar location efficiency can be improved, there is great promotion prospect.
