Description

Technical Field

[0001] The utility model relates to the technical field of reinforced concrete retaining walls, in particular to a C-shaped material grid retaining wall slot-type expansion joint structure. Background Art

[0002] With the improvement of national environmental protection requirements and the consideration of full utilization of land resources, many coking and metallurgical enterprises use reinforced concrete C-type material grids for material storage. C-type material yard has the advantages of small footprint, simple stacking and unloading process, multiple storage types, large storage volume, and good environmental protection effect.

[0003] In order to facilitate the storage of different types of materials and increase the storage capacity, the C-type material yard is divided into multiple C-type material grids by longitudinal and transverse retaining walls. However, the longitudinal retaining wall formed by multiple material grids is relatively long. In order to reduce the temperature deformation of the reinforced concrete structure, it is necessary to set longitudinal expansion joints that can be deformed freely at the deformation-sensitive position of the longitudinal retaining wall or at a certain distance. The traditional expansion joint directly breaks the longitudinal retaining wall, so that the out-of-plane constraint of the longitudinal retaining wall changes from three sides fixed and one side cantilever to two sides fixed and two sides cantilever. The weakening of the out-of-plane constraint around the longitudinal retaining wall will lead to an increase in the out-of-plane bending moment at the bottom of the longitudinal retaining wall and the out-of-plane deformation at the top, thereby increasing the amount of engineering work, resulting in high investment and poor economic benefits.

[0004] Therefore, in order to solve the problem that the traditional expansion joint structure of the existing C-type material grid causes unreasonable force on the longitudinal retaining wall and high cost, it is a technical problem that structural engineers need to solve urgently to find an expansion joint node structure with a simple structure that can not only meet the longitudinal free deformation of the longitudinal retaining wall to reduce the temperature internal force, but also ensure the external constraint of the longitudinal retaining wall. It is also a key problem that needs to be solved urgently to reduce project investment. Utility Model Content

[0005] In order to vigorously promote the application of C-type material grid material storage methods, to solve the environmental protection problems of material yards and make full use of land resources, and at the same time avoid the weakening of the constraints on the peripheral surface of the longitudinal retaining wall by traditional reinforced concrete expansion joints, the utility model aims to provide a slot-type expansion joint structure with a simple structure, which can ensure the longitudinal free expansion and contraction of the longitudinal retaining wall, constrain the deformation of the peripheral surface of the longitudinal retaining wall, and is easy to construct.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A trough body protruding from the wall surface of the horizontal retaining wall is provided on one side of the horizontal retaining wall at the intersection of the longitudinal and transverse retaining walls of the C-shaped material grid, one end of the longitudinal retaining wall is inserted into the trough body, a stainless steel plate sliding layer is provided between the longitudinal retaining wall inserted into the trough body and the side surface of the trough body, and a compressible elastically deformable material extruded plate is provided between the end of the longitudinal retaining wall inserted into the trough body and the trough body, forming a slot-type expansion joint structure in which the longitudinal retaining wall can freely expand and contract longitudinally and is fixedly constrained laterally.

[0008] Furthermore, the trough body is a reinforced concrete structure, which is arranged on any side of the transverse retaining wall at the junction of the longitudinal retaining wall and the transverse retaining wall, and protrudes from the transverse retaining wall surface. The trough body depth is 100mm to 200mm, and the trough body width and wall thickness are the same as the thickness of the longitudinal retaining wall. Furthermore, a U-shaped stainless steel plate with a curled edge is embedded inside the trough body as a sliding layer. The stainless steel plate has a thickness of 2mm to 6mm, and the specifications and dimensions are the same as the contour dimensions of the inner side of the trough body. The curled edge width is 20mm to 50mm, and it is arranged along the total height of the trough body.

[0009] Furthermore, an elastic material extruded plate which can be freely compressed and deformed is arranged in the tank body. The thickness of the extruded plate is 50mm to 100mm, the width of the extruded plate is the same as the width of the tank body, and the plate is arranged along the full height of the tank body.

[0010] Furthermore, the U-shaped stainless steel plate with curled edges and the extruded plate are embedded in the trough body, and the trough body is cast together with the longitudinal retaining wall and the transverse retaining wall. Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The slot-type structure can ensure that the longitudinal retaining wall can freely expand and contract longitudinally and can also ensure that the out-of-plane deformation around the longitudinal retaining wall is restrained in the lateral direction.

[0012] 2. The out-of-plane bending moment at the bottom and the out-of-plane deformation at the top of the longitudinal retaining wall are reduced, and the amount of concrete and steel bars are reduced by about 15%, which can reduce project investment.

[0013] 3. The node structure is simple, materials are easy to obtain, and construction is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
