Description
Technical field
The utility model is related to Tunnel Engineering technical applications, and in particular to a kind of tunnel lining reinforcing steel bar spacing combination control
Fabrication has.
Background technology
In current lining construction there are steel bar layer away from the control of, spacing it is not tight the problem of, so as to influence tunnel lining
The installation quality of reinforcing bar is built, makes lining construction quality and durability that can not be protected, reinforcing bar in existing tunnel lining construction
Layer is away from mainly using more people operation, labor intensity is big, and construction cost is high and complicated for operation, simultaneously as human factor influences
It is larger, there is a series of problems, such as control is not tight, does not control, leading to lining cutting steel bar layer, bar spacing does not meet design away from overproof
It is required that so as to finally influence the safety in tunnel.
Utility model content
The purpose of this utility model is to provide a kind of tunnel lining reinforcing steel bar spacing combination control card tool, in solution technology
Above-mentioned shortcoming.
To achieve these goals, the utility model provides following technical solution：A kind of tunnel lining reinforcing steel bar spacing combination
Fixture is controlled, including：Bar, longitudinal sliding motion bar, lock sleeve and locking nail are slid laterally, it is described to slide laterally bar and longitudinal sliding motion
The centre position of bar is provided with for slip through elongated slot, wherein, the length of longitudinal sliding motion bar, which is less than, slides laterally bar, and multiple
It is placed side by side on one or more to slide laterally on bar, be arranged vertically, the locking sleeve structure is wing nut, by being located at horizontal stroke
To the locking nail of sliding bar bottom face, the size of the distance between bar and longitudinal sliding motion bar as required will be slid laterally and required admittedly
It is scheduled on together.
Further, the lower face of the lock sleeve and the position of longitudinal sliding motion bar contact are equipped with rubber pad, convenient for lock
Fixed compression.
Further, the locking nail is followed closely for outer six square thread, and ailhead exists on the bottom face for slide laterally bar to be used
In the slip shallow slot of cooperation, convenient for tightening for lock sleeve.
Further, the diameter of thread of the locking nail is slightly less than the slip elongated slot slid laterally on bar and longitudinal sliding motion bar
Width.
In the above-mentioned technical solutions, a kind of tunnel lining reinforcing steel bar spacing combination control card tool provided by the utility model, leads to
Cross the elongated slot slid laterally on bar and longitudinal sliding motion bar, enable the fixture to the layers of different lining style reinforcing bars away from,
Away from being adjusted and locking, ensure that the layer of lining cutting reinforcing bar away from and spacing, it is ensured that the safety in tunnel, meanwhile, one can be complete
It is easy to operate into operation, it is easy to use, it is of low cost, it is reusable, it is applicable in the construction of all types of tunnel lining reinforcing steel bars.

Specific embodiment
In order to which those skilled in the art is made to more fully understand the technical solution of the utility model, below in conjunction with attached drawing pair
The utility model is further detailed.
Referring to shown in Fig. 1-2：
A kind of tunnel lining reinforcing steel bar spacing combination control card tool of the utility model, including：Slide laterally bar 1, longitudinal direction
Sliding bar 2, lock sleeve 3 and locking nail 4, the material for sliding laterally bar 1 and longitudinal sliding motion bar 2 are steel plate, intermediate position
It being provided with for slip through elongated slot, the width dimensions of elongated slot are slightly larger than the diameter of thread of locking nail 4, and longitudinal sliding motion bar 2
Length, which is less than, slides laterally bar 1, and multiple one or more that are placed side by side on slide laterally on bar 1, are arranged vertically, the locking
3 structures are covered for wing nut, and the locking nail 4 of 1 bottom face of bar is slid laterally by being located at, will slide laterally bar 1 and longitudinal sliding motion
The size of the distance between bar 2 as required requires to be fixed together, wherein, the lower face of the lock sleeve 3 and longitudinal sliding motion
The position that bar 2 contacts is equipped with rubber pad, convenient for the compression of lock sleeve 3.The locking nail 4 is followed closely for outer six square thread, ailhead
There is the slip shallow slot for cooperation on the bottom face for sliding laterally bar 1, convenient for tightening for lock sleeve 3.The locking nail 4
The diameter of thread is slightly less than the long well width of slip slid laterally on bar 1 and longitudinal sliding motion bar 2.
