Embodiment Construction

[0025] see figure 1 , figure 2 , in the present embodiment, the door-shaped support 7 is arranged longitudinally, and the longitudinal direction is the length direction of the arch culvert. On the top frame of the door-shaped support 7, two rows of supporting rollers 3 are arranged in parallel in the longitudinal direction; The mold trusses 2 are triangular structures composed of chords and diagonal braces, and the chords are supported by jacking cylinders 5 and rollers 3 fixedly arranged on the top frame of the portal frame 7; The screw 1 with adjustable length is connected between the diagonal braces, and the length of the screw 1 can be adjusted to adjust the expansion degree of the top mold 8;

[0026] The top mold 8 is hinged by steel pins 6 in the middle of the left and right circular arch sections to form a hinge structure; the left and right circular arch sections of the top mold 8 are respectively fixed and welded to the top mold truss 2 on the corresponding side; a...

Abstract

The invention discloses a semi-automatic arch culvert construction template. The semi-automatic arch culvert construction template is characterized in that a door-shaped support is arranged along the longitudinal direction, two columns of support rollers are arranged in parallel along the longitudinal direction on the top frame of the door-shaped support; two backform trusses which are bilaterally symmetrically arranged are respectively triangle structures composed of chord members and bracing pieces, wherein the chord member is supported by a jacking cylinder and a roller which are fixedly arranged on the top frame of the door-shaped support; the two bilaterally symmetrical backform trusses are connected between the bracing pieces by virtue of a lead screw with an adjustable length; a backform is hinged by a left circular arch section and a right circular arch section by virtue of a steel pin at the middle part; the left circular arch section and the right circular arch section of the backform are respectively fixed and welded on a backform truss at a corresponding side; a pair of side forms are respectively hung at the two ends of the backform; and an arch external mould is positioned and supported at the periphery of an arch internal mould composed of the backform and the side forms by virtue of a pull rod. The semi-automatic arch culvert construction template disclosed by the invention can greatly improve efficiency of arch culvert construction.

Description

technical field [0001] The invention relates to a formwork for arch culvert construction, more specifically a formwork system applied in the construction of arch culverts for roads and railways. Background technique [0002] At present, in the construction of arch culverts on railways and highways, steel pipe supports are mostly erected, and bamboo plywood is used to assemble composite arch culvert forms. This construction method has the following problems in practice: [0003] 1. The construction of steel pipe support is cumbersome and slow. [0004] 2. The bamboo plywood material is a non-recyclable material, and the utilization rate of the material is low, wasting cost and low social benefit. [0005] 3. The bamboo plywood material makes the surface of the concrete pouring molding uneven, which affects the appearance. Contents of the invention [0006] In order to avoid the above-mentioned shortcomings of the prior art, the present invention provides a semi-automatic ...
