Description

Arch ring support piece for grouted arch slope protection

Technical Field

The utility model relates to a mortar-laid slope protection, concretely relates to arch ring support piece for mortar-laid arch slope protection.

Background

At present, the arch bank protection mainly adopts two kinds of modes construction of mortar-laid bank protection and cast-in-place bank protection. The cast-in-place bank protection's structural strength is better compared with the grout bank protection, but its cost is high, needs the customization steel mould before cast-in-place. The steel die has the disadvantages of large self weight, inconvenient construction, high manufacturing cost and high construction cost, and is not beneficial to popularization. The grout bank protection adopts the mode form that the brickwork was built by laying bricks or stones, has better intensity, and the cost is low, uses more in the bank protection. However, the mortar-grouting construction method requires a certain support when the mortar is not dry in the initial stage. To solve the problem, field constructors often weld the iron sheet with the steel bars for shaping after bending the iron sheet into an arch on the field, and put the iron sheet at the position of the arch ring to support the masonry. The construction mode needs on-site manufacturing, and the construction efficiency is influenced. Meanwhile, the supporting device is simple to process, bears the weight load from one part of the masonry in the using process according to the long time, has low strength and is easy to deform after being used for a long time. In addition, the simple die manufactured on site has the problem of low arching precision, so that the built arch ring is not attractive enough and not accurate enough.

In order to solve the problems, the applicant wants to customize a batch of arch ring supporting pieces which are simple in structure, high in strength and small in self weight in a factory.

Disclosure of Invention

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide an arch ring support piece that is used for thick liquid arch bank protection that simple structure, and intensity is high, and the dead weight is little.

In order to solve the technical problem, the utility model discloses a following technical scheme:

an arch ring support member for grouted arch protection slope is characterized by comprising an arch support consistent with the design process requirements of an arch ring, wherein an arch surface of the arch support is detachably provided with a layer of iron sheet for completely covering the arch surface; the arched support comprises at least two arched reinforcing steel bars arranged at intervals, a plurality of connecting rods are arranged between the arched reinforcing steel bars at intervals, and the connecting rods and the arched reinforcing steel bars form an arched surface of the arched support; and an arch surface support connected with the arch surface is also arranged in the semi-enclosed space formed by the arch surface. Like this, the arch-shaped support arch-forming surface mainly comprises arch reinforcing bar and connecting rod, the arch reinforcing bar can provide more standard arching curve for the iron sheet, and the connecting rod forms a whole after with arch reinforcing bar connection, provides the assembly face for the iron sheet after the installation not only can have better support strength under the effect of connecting rod and arch reinforcing bar, and arching height and arching radian can be corresponding with the designing requirement moreover. The iron sheet is detachably connected with the arched bracket, so that the iron sheet can be conveniently mounted and dismounted. Above-mentioned arch ring support piece mainly comprises arch support and iron sheet, simple structure, and arch support intensity is high, and the dead weight is less, the later stage installation of being convenient for.

Further, the arch face supports including establishing the square pipe between two arch feet of every arch reinforcing bar, has a journal stirrup at the both ends fixed mounting who manages square pipe, the journal stirrup all is equipped with a through-hole in every journal stirrup middle part along the width direction setting of square pipe. Like this, the steel pipe that sets up can prevent that long-term heavy pressure from pushing down the arch reinforcing bar and warp, can play the effect of stereotyping to the arch reinforcing bar, can increase the intensity of arched bracket simultaneously. Meanwhile, the square tube is hollow inside and has small self weight.

Furthermore, a vertically arranged reinforcing pipe is arranged in the middle of each square pipe, L-shaped connecting plates are arranged on the left side and the right side of the lower end of each reinforcing pipe, one side of each connecting plate is fixed with the corresponding reinforcing pipe in a welding mode, and the other side of each connecting plate is fixed with the corresponding square pipe in a bolt mode; the front side and the rear side of the top end of the reinforcing pipe extend out of the arched reinforcing steel bars to form a U-shaped groove for clamping the arched reinforcing steel bars. Like this, the reinforcement pipe that sets up can support arch reinforcing bar middle part, simultaneously, strengthens the joint strength of arch reinforcing bar and square pipe. The reinforced pipe adopts the upper end chucking cooperation, and the lower extreme is installed with connecting plate and bolt fastening's mode, and the installation of reinforced pipe can be convenient for to this kind of fixed mode, during the assembly, earlier with the upper end chucking cooperation back, fixed lower extreme again.

Furthermore, at least one reinforcing transverse pipe is fixedly arranged between the two square pipes. Thus, the connection strength between the square pipes can be increased.

Furthermore, at least one reinforcing diagonal rod with one end fixed with the reinforcing pipe and the other end fixed with the arched steel bars is arranged on two sides of each reinforcing pipe. In this way, the arranged reinforcing inclined rod can effectively share part of external pressure, and meanwhile, the strength of the reinforcing pipe is increased.

Furthermore, four mounting holes which are in one-to-one correspondence with the through holes in the support lugs are formed in four corners of the iron sheet, and the iron sheet is installed on the arched support after penetrating through the mounting holes and the through holes through bolts and being matched with the bolts through nuts. Therefore, four corners of the iron sheet are fixedly installed through bolts, and the iron sheet can be detachably installed.

Furthermore, a plurality of connecting holes are formed in the iron sheet and adjacent to the arched reinforcing steel bars or the connecting rods, and an iron wire for binding and fixing the iron sheet and the arched reinforcing steel bars or the iron sheet and the connecting rods is arranged on each connecting hole. Therefore, the connecting holes and the iron wires can strengthen the connecting points between the arch camber parts of the arch-shaped supports and the iron sheet, and after the arch camber parts are connected at multiple points, the iron sheet can be prevented from displacing, and the connecting strength of the arch camber parts is improved.

Further, a layer of waterproof paint is arranged on the iron sheet. Therefore, the iron sheet cannot be corroded due to the infiltration of water in the building block mortar, and the service life of the iron sheet can be effectively prolonged. Simultaneously, the smoothness degree on iron sheet surface can be increased after painting, thereby being convenient for taking down the supporting piece from the arch ring in the later period.
