Problems solved by technology

[0002] In tunnel construction, when casting the tunnel roof, it is necessary to use many support rods and support plates to complete. Basically, the support frame is slowly built, and then the prepared curved steel plate is placed and fixed on the support frame. On the other hand, this method is very time-consuming and labor-intensive

Embodiment 1

[0017] Such as figure 1 , figure 2 As shown, the arc-shaped mold for tunnel casting includes an arc-shaped structural steel plate 3, and at least two steel pipes 2 fixed along the inner arc surface and having an arc-shaped structure are arranged in parallel on the inner arc surface of the steel plate 3. The steel pipe 2 The two ends are connected by a crossbeam 4, a longitudinal reinforcing rib 1 is arranged between the crossbeam 4 and the inner arc surface of the steel pipe 2, and at least two transverse reinforcing ribs 6 are arranged between the crossbeams 4.

[0018] In this embodiment, at least two connecting rods 5 are arranged on the beam 4, and the connecting rods 5 and the beam 4 are hinged together; the distance between the adjacent connecting rods 5 is 25 cm; the distance between the adjacent steel pipes 2 The distance between them is 50cm; the distance between the adjacent transverse ribs 6 is 80cm.

[0019] When making, first make the steel pipes 2 of arc-shape...

Embodiment 2

[0022] Changes are made on the basis of Embodiment 1, changing the distance between the adjacent connecting rods 5 to 40cm; the distance between the adjacent steel pipes 2 to 60cm; the distance between the adjacent transverse ribs 6 It is 100cm.

[0023] Others are the same as embodiment one.

Embodiment 3

[0025] Change on the basis of Embodiment 1, change the distance between the adjacent connecting rods 5 to 50cm; the distance between the adjacent steel pipes 2 to 80cm; the distance between the adjacent transverse ribs 6 It is 150cm.

[0026] Others are the same as embodiment one.

Abstract

The invention relates to an arc-shaped mould for tunnel pouring and belongs to the technical field of arc-shaped moulds. The arc-shaped mould for tunnel pouring comprises an arc-shaped structural steel plate, at least two steel pipes which are fixed along an inner arc face and are each of an arc-shaped structure are parallelly arranged on the inner arc face of the steel plate, and the two ends ofthe steel pipes are connected through cross beams. Longitudinal reinforcing ribs are arranged between the cross beams and the inner arc face of the steel pipe, and at least two transverse reinforcingribs are arranged between the cross beams. Through the arc-shaped mould for tunnel pouring, the structure is simple, and under the design, the adaptive moulds can be manufactured according to the sizerequirement of a tunnel and then conveyed to a site; and a model of the steel plate is fixed well, thus only supporting needs to be conducted on site, mould supporting is very convenient, and the time and labor are saved.

Description

technical field [0001] The invention relates to an arc mold for tunnel pouring, belonging to the technical field of arc molds. Background technique [0002] In tunnel construction, when casting the tunnel roof, it is necessary to use many support rods and support plates to complete. Basically, the support frame is slowly built, and then the prepared curved steel plate is placed and fixed on the support frame. On the other hand, this method is very time-consuming and labor-intensive. Contents of the invention [0003] Based on the above deficiencies in the prior art, the technical problem to be solved by the present invention is: to provide an arc-shaped mold for tunnel pouring, which has a simple structure, is very convenient for forming, and saves time and effort. [0004] The arc-shaped mold for tunnel pouring according to the present invention includes an arc-shaped structural steel plate, and is characterized in that: at least two steel pipes fixed along the inner arc...
