A shed structure

Abstract

The present invention discloses a shed hole structure, including a shed hole panel, the main body of the shed hole panel is a concrete slab, the concrete slab is made of a corrugated steel plate as a bottom membrane, and a plurality of compression springs are welded to the bottom of the corrugated steel plate; a side frame for support is arranged at the edge of the shed hole panel, and the shed hole panel is butted with the side frame through the compression spring; a space is left between the corrugated steel plate at the bottom of the shed hole panel and the top of the side frame; a sliding bolt is also arranged between the shed hole panel and the side frame for fixing the two. The sinusoidal corrugated steel web at the bottom of the concrete panel improves the overall tensile strength and bending stiffness of the concrete panel, and under the same strength, the amount of steel used can be greatly reduced and the dead weight can be reduced; at the same time, the deformation capacity of the compression spring is utilized to consume part of the impact energy, thereby improving the buffering capacity of the panel and reducing the stress of the entire structure. When the shed hole panel is damaged, it can also be partially replaced in time.

Description

Technical Field

[0001] The invention relates to the technical field of highway construction safety protection, in particular to a shed tunnel structure. Background Art

[0002] At present, the construction of highways in mountainous areas of my country has entered a period of full-speed development. However, the terrain in mountainous areas is steep, and secondary disasters such as falling rocks and rolling stones are very likely to occur, which brings great risks to the smoothness of the road and driving safety. Therefore, in the process of highway construction, open holes or shed tunnel structures are often used to protect roads from falling rocks. The two structures have their own advantages and disadvantages. The open hole structure adopts an overall box-type structure, and each node adopts a consolidated connection. The overall force performance is good and the impact resistance is strong, but once damaged, it often needs to be replaced as a whole, which is inconvenient; the shed tunnel structure is a simply supported structure of a rack + top beam, and the impact resistance is poor. However, when one of the top plates is damaged by falling rocks, only the damaged part can be repaired, which is convenient and quick. How to improve the impact resistance of the shed tunnel and make it the "main force" of rockfall protection has become one of the problems that need to be solved at present. Summary of the invention

[0003] In view of the defects existing in the prior art, the object of the present invention is to provide a shed cave structure.

[0004] The present invention is achieved through the following technical solutions:

[0005] A shed hole structure, comprising a shed hole panel, wherein the main body of the shed hole panel is a concrete slab, the concrete slab has a corrugated steel plate as a bottom membrane, and a plurality of compression springs are welded to the bottom of the corrugated steel plate;

[0006] The edge of the shed hole panel is provided with a side frame for support, and the shed hole panel is butted with the side frame through a compression spring; a space is left between the corrugated steel plate at the bottom of the shed hole panel and the top of the side frame;

[0007] Sliding bolts are also provided between the shed hole panel and the side racks to fix the two.

[0008] In the present invention, the concrete slab is cast with the corrugated steel plate as the base membrane, so that the tensile strength and bending strength of the bottom of the panel during the impact of the concrete slab are improved, and the flexibility of the corrugated steel plate can also be used; at the same time, a compression spring is welded at the bottom to connect the panel with the rack, and during the impact, the shed hole panel has a certain deformation space, and a part of the impact energy is consumed by the deformation of the compression spring, thereby improving the buffering capacity of the panel and reducing the stress of the entire structure; sliding bolts are used to fix the shed hole panel and the side racks, so as to achieve stability when the panel is installed and impacted, and at the same time, if the panel is partially damaged in the impact of falling rocks, it can be replaced in time.

[0009] Further technical solutions are:

[0010] Steel bars are welded through the top of the corrugated steel plate to strengthen the connection and bite between the corrugated steel plate and concrete.

[0011] The material used for concrete slabs is foamed concrete, which is only 1 / 3 to 1 / 2 of ordinary concrete, ensuring the lightness of the panel. It has good compatibility with other building materials and its strength can be adjusted as needed.

[0012] The side frame is butted against the compression spring through a spring groove arranged on the top thereof, and the size of the spring groove matches the compression spring. The compression spring is placed in the spring groove, which further improves the stability of the shed hole panel during installation and impact.

[0013] Preferably, a compression spring is welded to the bottom of the corrugated steel plate every 50 to 80 centimeters.

[0014] Preferably, the corrugated steel plate used is sinusoidal corrugated steel.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The overall tensile strength and bending stiffness of the concrete panel are improved, and at the same strength, the amount of steel used can be greatly reduced and the dead weight can be reduced; a detachable connection method is adopted between the shed panel and the side bracket. When the panel is partially damaged, only the damaged part can be partially replaced. BRIEF DESCRIPTION OF THE DRAWINGS
