Description
Technical Field
The utility model relates to the technical field of tunnel construction, in particular to a rapid positioning frame for mounting secondary lining reinforcing steel bars of a tunnel.
Background
In tunnel construction, for the durability of reinforcing concrete lining, need set up the tunnel protective layer, prevent that structural reinforcement from taking place the corrosion in design basic period, the protective layer thickness is thin can produce and leak the muscle, protective layer thickness is too big and seriously influences secondary lining structure atress again, consequently, must control the protective layer thickness according to the design requirement, in the work progress, because structural reinforcement interval is difficult to control, when concrete placement, the reinforcing bar is very easily out of shape after the pressurized and is shifted and push down the waterproof layer, lead to protective layer thickness unqualified.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide a rapid positioning frame for mounting a tunnel secondary lining reinforcing steel bar.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a tunnel secondary lining reinforcing steel bar installation rapid positioning frame which comprises a pair of angle steels which are arranged in parallel relatively, wherein the opposite surfaces of the two angle steels are provided with adjusting holes, an adjusting screw rod is arranged between the adjusting holes, adjusting nuts are arranged on the two sides of the adjusting holes, the adjusting nuts are in threaded connection with the adjusting screw rod, a plurality of positioning holes which are distributed at intervals are formed in the angle steels along the length direction, and reinforcing steel bars are installed in the positioning holes. The positioning holes are manufactured according to the steel bar spacing, and the double rows of steel bar spacing can be adjusted through the adjusting screw rods, so that the steel bar spacing and the thickness of the protective layer are guaranteed.
The angle steel is L-shaped, the adjusting holes are formed in the vertical edges of the angle steel, and the positioning holes are formed in the horizontal edges of the angle steel. The angle steel of L type intensity is high, and non-deformable avoids when concrete placement, takes place to warp after the pressurized, leads to protective layer thickness nonconforming.
The utility model preferably adopts the technical scheme that the adjusting screw is perpendicular to the angle steel. The angle steels on the two sides are ensured to be kept parallel.
The utility model has the preferable technical scheme that a plurality of adjusting screws are arranged, and the spacing distance between the adjusting screws is equal to 2 m. The angle steel is ensured to have the same spacing distance along the length direction.
The utility model has the preferable technical scheme that a plurality of pairs of angle steels are arranged at intervals along the length direction of the steel bars. Through a plurality of angle steel positioning reinforcing bars, the interval distance from top to bottom of the reinforcing bar can be adjusted according to the requirements.
The utility model has the preferable technical scheme that the size of the opening of the positioning hole is equal to the diameter of the reinforcing steel bar. The reinforcing bar is directly blocked in the locating hole, and the reinforcing bar is conveniently fixed by an operator.
The utility model has the beneficial effects that:
the utility model provides a tunnel secondary lining reinforcing steel bar installation rapid positioning frame which comprises a pair of angle steels which are arranged in parallel relatively, wherein the opposite surfaces of the two angle steels are provided with adjusting holes, an adjusting screw rod is arranged between the adjusting holes, adjusting nuts are arranged on the two sides of the adjusting holes, the adjusting nuts are in threaded connection with the adjusting screw rod, a plurality of positioning holes which are distributed at intervals are formed in the angle steels along the length direction, and reinforcing steel bars are installed in the positioning holes. According to the reinforcing bar interval preparation locating hole, according to the demand, through rotatory adjusting nut, flexible adjusting screw to adjustable double reinforcing bar interval, thereby guarantee reinforcing bar interval and protective layer thickness.

Detailed Description
The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.
As shown in the figure, this embodiment provides a quick locating rack of tunnel secondary lining steel bar installation, including a pair of angle steel 1 that is relative parallel arrangement, two be equipped with regulation hole 2 on the opposite face of angle steel 1, be equipped with adjusting screw 3 between the regulation hole 2, 2 both sides in regulation hole are equipped with adjusting nut 4, 4 threaded connection of adjusting nut in on the adjusting screw 3, set up a plurality of intervals locating hole 5 of arranging along length direction on the angle steel 1, the reinforcing bar 6 is installed in locating hole 5. According to 6 intervals of reinforcing bar preparation locating hole 5, according to the demand, through rotatory adjusting nut 4, flexible adjusting screw 3 to 6 intervals of adjustable double reinforcing bar, thereby guarantee 6 intervals of reinforcing bar and protective layer thickness.
The angle steel 1 is L-shaped, the adjusting hole 2 is formed in the vertical edge of the angle steel 1, and the positioning hole 5 is formed in the horizontal edge of the angle steel 1. The L-shaped angle steel 1 is high in strength and not easy to deform, and deformation caused after compression when concrete is poured is avoided, so that the thickness of a protective layer is unqualified.
The adjusting screw 3 is perpendicular to the angle steel 1. The angle steel 1 on the two sides is ensured to be parallel, so that the thickness of the protective layer is ensured to be the same.
The adjusting screws 3 are multiple, and the spacing distance between the adjusting screws 3 is equal to 2 m. Guarantee angle steel 1 along length direction interval distance all the same, and set up interval distance and be 2m, can guarantee that interval distance between angle steel 1 can not be because of taking place to warp when concrete placement, lead to interval distance to change.
