Steel formwork for road construction

Abstract

The utility model relates to a steel formwork for road construction. The steel formwork comprises a steel formwork panel, a first flange plate, a second flange plate, connecting bolts and a rubber plate. The first flange plate is vertically fixed at one end of the outer side surface of the steel mould panel, and a first connecting hole is formed in the first flange plate; the second flange plate is perpendicularly fixed to the other end of the outer side face of the steel formwork face plate, and second connecting holes corresponding to the first connecting holes are formed in the second flange plate. The connecting bolt is arranged in the second connecting hole of the second flange plate in a penetrating manner; the rubber plate is fixed to the outer side face of the second flange plate. When the steel formwork is used, due to the fact that the first flange plate and the second flange plate are both perpendicularly and fixedly connected with the steel formwork face plate, a large supporting bottom face can be formed, the steel formwork is not prone to inclination when being placed on a road construction base layer, the perpendicularity of the steel formwork can be guaranteed, and when the steel formworks are spliced and combined, operation is very simple; and the construction efficiency can be improved.

Description

Technical Field

[0001] The utility model belongs to the technical field of road construction, and particularly relates to a steel formwork for road construction. Background Art

[0002] During the process of road surface concrete construction, because concrete has fluidity, it is necessary to use segmented and combined steel formworks to support the concrete to ensure that the concrete does not overflow, and to construct according to the measured road surface trend, ensure the thickness of the road surface concrete, and at the same time facilitate the subsequent vibration and compaction of the concrete.

[0003] At present, the steel formworks for road construction mainly adopt channel steel structures. The steel formworks are connected by setting connection structures between them. For example, a road construction formwork disclosed in patent number CN212801120U and a steel formwork connection structure disclosed in patent number CN217810379U. The existing steel formworks have the following problems: 1. The steel formworks with channel steel structures are prone to tilt after being erected, unable to ensure verticality, and the connection structures set between the steel formworks are relatively complex, and the assembly time is relatively long, which is not conducive to improving the construction efficiency; 2. There is a lack of anti-leakage measures between the steel formworks, and the concrete is prone to leak from the connection between the two. Summary of the Utility Model

[0004] The main purpose of the utility model is to propose a steel formwork for road construction, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0032] The first flange 2 is vertically fixed at one end of the outer side of the steel formwork panel 1, and a first connection hole 21 is provided on the first flange 2; the second flange 3 is vertically fixed at the other end of the outer side of the steel formwork panel 1, and a second connection hole 31 corresponding to the first connection hole 21 is provided on the second flange 3; the connecting bolt 4 is inserted into the second connection hole 31 of the second flange 3; the rubber plate 5 is fixed on the outer side of the second flange 3.

[0033] The working principle of the present utility model is:

[0034] When the steel formwork is in use, since both the first flange plate 2 and the second flange plate 3 are vertically and fixedly connected to the steel formwork panel 1, a relatively large supporting bottom surface can be formed. When the steel formwork is placed on the road construction base course, it will not easily tilt, which can ensure the verticality of the steel formwork. When the steel formworks are spliced and combined, the outer side surface of the first flange plate 2 of the steel formwork to be connected is abutted against the rubber plate 5 of the installed steel formwork, and the first connection holes 21 and the second connection holes 31 of the two are aligned. Then, the second flange plate 3 of the installed steel formwork and the first flange plate 2 of the steel formwork to be installed are fixed by passing the connecting bolts 4 through the first connection holes 21 and the second connection holes 31, so that the two steel formworks can be connected. The operation is very simple, which is beneficial to improving the construction efficiency. The rubber plate 5 is squeezed between the two steel formworks, which can effectively prevent the concrete from leaking from the connection part between the two.

[0035] In a specific embodiment, it further includes a support frame 6 and a fixing column 7; the support frame 6 is used to support the outer side surface of the steel formwork panel 1. By supporting the outer side surface of the steel formwork through the support frame 6, the outward movement of the steel formwork during concrete pouring can be prevented; the fixing column 7 is fixedly connected to the support frame 6 and is inserted into the ground for fixing the support frame 6.

[0036] In a specific embodiment, the support frame 6 is a triangular frame structure, and one side abuts against the outer side surface of the steel formwork panel 1. The triangular frame structure is light in weight, and by using one side to support the steel formwork, a relatively large support range can be provided to ensure the support effect.

[0037] In a specific embodiment, the fixing column 7 is a round steel, and the bottom end is provided with a pointed head for convenient insertion into the ground.

[0038] In a specific embodiment, the steel formwork panel 1, the first flange plate 2, and the second flange plate 3 are integrally formed.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
