Example Embodiment

[0008] Such as figure 1 As shown, the present invention is composed of channel steel 1 (the same thickness as the road surface) and a triangle bracket 3. The triangle bracket 3 is connected to the channel steel 1 through a sleeve 2 welded to the channel steel (concave surface), and the other end of the triangle bracket Connected to the straight sleeve 4, the straight sleeve 4 has insert ribs 5, and the triangle bracket can be adjusted up and down. Both ends of the channel steel 1 are provided with sleeves 6 at the formwork joints, and there are joint pins 7 in the sleeves 6 at the formwork joints to avoid deformation of street parts. When disassembling the mold, take out the plugs at the joints, pull out the fixed inserts, and remove the template. The plugs and fixed inserts can be reused.

Abstract

The invention provides a pavement concrete channel steel forming formwork which comprises a channel steel and a triangular support, wherein the triangular support is connected with the steel channel through a sleeve welded on the concave surface of the channel steel; the other end of the triangular support is connected with a straight sleeve; an inserting rib is arranged in the straight sleeve; formwork joint sleeves are arranged at two ends of the channel steel; and joint inserting pins are arranged in the formwork joint sleeves. According to the steel channel forming formwork for pavement concrete construction, the formwork is convenient to build and remove; and the steel channel forming formwork can be repeatedly utilized, has low cost, and is beneficial to control the forming quality of the concrete.

Description

technical field [0001] The invention belongs to the technical field of highway engineering, and in particular relates to a channel steel shaping formwork used for road surface concrete construction. Background technique [0002] At present, in pavement concrete engineering, in addition to using conventional vertical formwork to pour pavement concrete, more channel steel is used as side formwork, and channel steel formwork is fixed by internal or external braces, which requires frequent construction. Stretching is not only a waste of materials, but also time-consuming and labor-intensive. If the construction quality is not strictly controlled, the formwork is easily deformed, which will affect the quality of concrete molding. Contents of the invention [0003] The purpose of the present invention is to overcome the drawbacks of the traditional channel steel formwork, such as frequent reinforcement, waste of materials, time-consuming and labor-intensive work, and disadvantag...
