Abstract
The utility model is a kind of constructing tunnel Reinforcing bar clamp, and it includes longitudinal register steel pipe, reinforcing bar latch, and reinforcing bar latch is fixed on longitudinal register steel pipe, and reinforcing bar latch is that two screw-thread steels form neck, thus forms Reinforcing bar clamp.Constructing tunnel Reinforcing bar clamp simple operation of the present utility model, it is reusable, be advantageous to improve tunnel reinforcement construction efficiency and quality control.
Description
Technical field
The utility model belongs to tunnel construction technical field, and in particular to a kind of constructing tunnel Reinforcing bar clamp.
Background technology
In recent years, as China's traffic base construction scale constantly increases, construction standardization requires more and more higher.Tunnel two
Lining is used as tunnel permanent support part, and two lined steel muscle are generally equipped with ring, longitudinal reinforcement, connection reinforcing bar, and tunnel double-lining reinforcing bar is determined
Position is the weak link of tunnel quality control.At present, two lined steel muscle colligations generally first use coil of strip on cableway, steel bar stress
Chi and slate pencil mark cage bar, distributing reinforcement, the spacing of stirrup, then carry out reinforcing bar colligation.The technological operation is inconvenient, efficiency of construction
It is low.
In concrete construction, because of reasons such as collision, concrete vibratings, off-position of steel reinforcing bar is easily caused, influences matter of constructing
Amount.
The conventional assembling reinforcement on cableway, even if taking outer pad protective layer cushion block, also easily cause cover to reinforcement
Do not reach requirement, cause to occur phenomena such as leaking muscle.
The content of the invention
The purpose of this utility model is to provide a kind of constructing tunnel Reinforcing bar clamp, effective in tunnel double-lining reinforcement construction
Ring bar spacing and thickness of concrete cover are controlled, and it is easy for construction.
The technical solution of the utility model is：A kind of constructing tunnel Reinforcing bar clamp includes longitudinal register steel pipe, reinforcing bar latch,
Reinforcing bar latch is fixed on longitudinal register steel pipe, and reinforcing bar latch is that two screw-thread steels form neck, thus forms Reinforcing bar clamp.
Superiority of the present utility model be embodied in it is following some：
1st, the Reinforcing bar clamp makes simple, and cost is low.
2nd, tunnel circumferential reinforcement spacing and thickness of concrete cover can effectively be controlled.
3rd, the Reinforcing bar clamp can be used for full tunnel reinforcement construction, practical.
4th, the Reinforcing bar clamp be may move, and rigidity is preferable, and reuse is unlikely to deform, and operation is flexible.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, for ordinary skill people
For member, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is constructing tunnel Reinforcing bar clamp structural representation of the present utility model（Plan）.
Fig. 2 Fig. 1 drawing in side sectional elevation.
In figure：1- longitudinal register steel pipes；2- reinforcing bar latches；3- tunnels circumferential reinforcement.
Embodiment
As shown in figure 1, a kind of constructing tunnel Reinforcing bar clamp includes longitudinal register steel pipe 1, reinforcing bar latch 2, reinforcing bar latch is consolidated
It is scheduled on longitudinal register steel pipe, reinforcing bar latch is that two screw-thread steels form neck, thus forms Reinforcing bar clamp.
The utility model just props up the joint bar set up using the ring cage bar and tunnel constructed, and is suspended on and is just provided on branch face
Positioning action.Reinforcing bar clamp initiating terminal is fixed in the cage bar for terminating inverted arch concrete of having constructed, and frame is made in centre with ring cage bar
Stud is supported reinforcing, and end sets joint bar to be hung on tunnel Chu Zhi faces.
Described longitudinal register steel pipe uses the steel pipes of φ 42, the long 6m in longitudinal direction, 2 is welded according to design bar spacing on steel pipe
The screw-thread steels of φ 12 are as reinforcing bar latch, and length 7cm, the spacing of two reinforcing bars is the circumferential reinforcement diameter+2mm of design, is used for
Fixed circumferential reinforcement；Often locate reinforcement welding spacing（Middle centering）=design bar spacing.
The utility model proposes Reinforcing bar clamp can improve tunnel reinforcement installation efficiency of construction and construction quality, reduce production
Cost, reduce cableway construction quantity；Bar spacing and protective layer control errors effectively improve reinforcement installation within 10mm
Quality.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
