Description
Technical Field
The utility model relates to a tunnel construction technical field, in particular to steel shotcrete fixing device for excavation supporting field.
Background
With the development of tunnel engineering, more and more cities begin tunnel traffic construction. Tunnel traffic construction often can involve foundation ditch engineering, and the steel shotcrete is comparatively common bearing structure form as the interior support system of foundation ditch engineering, and the steel shotcrete is used for strutting, blocks the soil body behind the foundation ditch, prevents that the foundation ditch from collapsing, extensively uses in subway construction.
This type of device generally adopts the U shaped steel muscle at present to fix the steel shotcrete in inside to carry out the steel shotcrete with the mode in the hole that the shaped steel roof beam was reserved in the installation of U shaped steel muscle both ends and fix. Because U shaped steel muscle lower part and steel shotcrete do not laminate completely, it is very firm not to make steel shotcrete and shaped steel roof beam fixed, and in case the reinforcing bar is lax, be equivalent to between steel shotcrete and the shaped steel roof beam not have any fixed measure, when placing the steel shotcrete, do not have any bradyseism device between steel shotcrete and the shaped steel roof beam, easily cause certain damage for the steel shotcrete, and need loosen U shaped steel muscle during the pressurization, make work more complicated, consequently need to open and shut at present conveniently, bradyseism, the fault-tolerant rate is high and fixed more firm steel shotcrete fixing device.
SUMMERY OF THE UTILITY MODEL
In order to overcome among the steel shotcrete fixing device prior art steel shotcrete easily receive vibrations and steel shotcrete and shaped steel roof beam fixed insecure, the utility model provides a fixing device for steel shotcrete and shaped steel roof beam, this fixing device can not only reduce the collision of steel shotcrete and shaped steel roof beam, can compensate the fixed insecure shortcoming of steel shotcrete and shaped steel roof beam moreover, improves the fault-tolerant rate, makes the construction more convenient.
The utility model adopts the following technical proposal:
the utility model provides a fixing device for steel shotcrete and shaped steel roof beam, includes base, arc shaped steel board, rubber pad, hinge, bolt, handle and laser inscription district, the base is the recess of bottom for the rectangle, the arc shaped steel board is the semicircle steel board, the base passes through welded fastening with the shaped steel roof beam.
Preferably, one side between the arc-shaped steel plate and the base is connected through a hinge, and the other side is fixed through a bolt.
Preferably, the base and the arc-shaped steel plate are made of stainless steel.
Preferably, a rubber pad is arranged in the base, is embedded in the inner wall of the base and is of an integrated structure with the base.
Preferably, the side surface of the base is provided with a laser inscription area of the steel support number position information.
Preferably, a handle for opening the arc-shaped steel plate is arranged at the upper part of the arc-shaped steel plate.
The utility model has the advantages that: (1) the inner wall of the steel support fixing device is provided with the rubber pad, so that the impact force between the steel support and the base can be reduced, the shock resistance of the steel support is improved, and the service life of the steel support is prolonged. (2) The base and the arc-shaped steel plate are made of stainless steel materials, corrosion resistance is achieved, and the problems of oxidation and cracking of the rubber pad are effectively solved. (3) The side surface of the base is additionally provided with a laser inscription area, so that the number and position information of the steel support can be effectively distinguished. (4) The steel support is completely attached to the inner space of the steel support fixing device, so that the steel support and the section steel beam are fixed more firmly.

Fig. 2 is a plan view of the steel support fixture.
Wherein, 1 base, 2 arc steel sheets, 3 rubber pads, 4 hinges, 5 bolts, 6 handles, 7 laser inscription district.
Detailed Description
The utility model is described in detail with the following figures:
the utility model provides a fixing device for steel shotcrete and shaped steel roof beam, including base 1 and arc steel sheet 2, pass through welded connection between base 1 and the shaped steel roof beam, can effectively prevent to adopt when bolted connection to rock because of the bolt is not hard up, one side is passed through hinge 4 and is connected between base 1 and the arc steel sheet 2, conveniently open and shut, the opposite side passes through bolt 5 and connects, fixing device is inside to have the cylinder space of laminating steel shotcrete completely after the closure, inside rubber pad 3 that is provided with of lower semicircle at fixing device, be provided with laser inscription district 7 in base 1 side, 2 upper portions of arc steel sheet are provided with handle 6.
The steel plate that base 1 and 2 homonymy knecks of camber steel sheet have the level to outwards extend a short distance passes through bolt 5 to be fixed two steel sheets, makes base 1 inseparable with 2 closures of camber steel sheet.
The rubber pad 3 arranged inside the arc of the base 1 can relieve the collision of the steel supports on the section steel beam and improve the anti-seismic performance of the steel supports.
The laser inscription area 7 that sets up in base 1 side can effectively solve and is difficult for discerning the problem of steel shotcrete serial number positional information under the foundation ditch.
The handle 6 is arranged on the upper portion of the arc-shaped steel plate 2, the U-shaped bent handle 6 can prevent slipping, and meanwhile the fixing device is convenient to open and close.
In the use, when the steel shotcrete needs to be added, unscrew bolt 5 on one side of the fixing device, hold handle 6 and lift arc-shaped steel plate 2 upwards, hinge 4 takes place to rotate this moment, arc-shaped steel plate 2 is opened, the steel shotcrete is slowly placed in the fixing device who opens through the crane, reduce the impact force to the shaped steel roof beam that hoist and mount steel shotcrete and produce with the help of the deflection of rubber pad 3, when the steel shotcrete is steadily placed in fixing device, closed arc-shaped steel plate 2, make base 1 and arc-shaped steel plate 2 seal, the kneck is through screwing up bolt 5, firmly be fixed in on the shaped steel roof beam with the steel shotcrete, the steel shotcrete is fixed and is ended.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
