Description

Technical Field

[0001] This utility model relates to the field of concrete construction, and in particular to an anti-corrosion steel lining for the surface of concrete structures. Background Technology

[0002] In certain construction areas (such as impact-resistant and wear-resistant concrete surfaces or other special construction areas), adding a steel lining to the concrete surface can increase its resistance to corrosion. However, in order to reduce costs, the steel lining is not made of thick steel plates (the conventional steel plates are 20mm~30mm thick), and there is a risk of deformation during the installation and concrete pouring process. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an anti-corrosion steel lining for the surface of concrete structures, which solves the problems of insufficient strength, easy deformation, and difficulty in transportation and installation of steel lining.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A corrosion-resistant steel liner for the surface of a concrete structure includes a liner body, a steel mesh reinforced on the back of the liner body and a concrete layer poured thereon; the concrete layer covers the main area of ​​the steel mesh and the liner body, and a reserved area is provided for the influence of the weld seam at the edge of the liner body.

[0006] The back of the liner body is provided with transverse and longitudinal ribs, and both the liner body and the ribs are made of steel plates.

[0007] The rib plate has multiple through holes spaced apart along its length, through which the reinforcing bars pass and are tied into a reinforcing mesh.

[0008] The thickness of the concrete layer shall not be less than 15cm, and the aggregate gradation shall not be less than C30.

[0009] The thickness of the liner body is 20mm-30mm.

[0010] The back of the liner body is welded with a lifting lug at an appropriate position on the rib plate.

[0011] A connector is welded to the back of the liner body at an appropriate position on the rib plate.

[0012] The bottom of the support body is equipped with a support plate, and the lower end of the support plate is connected to the support body through a spring telescopic rod. The support plate is equipped with rollers.

[0013] This utility model provides an anti-corrosion steel lining for the surface of concrete structures, which has the following technical effects:

[0014] 1) By adding a steel mesh and a concrete layer to the back of the steel lining, the problems of insufficient strength and easy deformation of the steel lining are solved, and the deformation resistance during the installation of the steel lining or the pouring of concrete is improved.

[0015] 2) Prefabricated semi-finished products have fixed shapes and high strength, so they need to be padded with wooden blocks or fixed with special transport brackets during transportation.

[0016] 3) Prefabricated semi-finished products are easy to position during installation due to their fixed shape, which facilitates construction and verification. Attached Figure Description

[0022] like Figure 1-3 As shown, an anti-corrosion steel lining for concrete structures includes a lining body 1, which is a steel plate with a thickness of 20 mm. Ribs 4, also made of steel plate, are provided on the back of the lining body 1. A reinforcing mesh 2 is added to the back of the lining body 1, and a concrete layer 3 of a certain thickness is poured, thereby increasing the overall strength of the steel lining.

[0023] The rib plate 4 of the liner body 1 has through holes arranged at intervals along the length direction, and the reinforcing bars pass through the corresponding through holes and are tied into a reinforcing mesh 2.

[0024] The thickness of the concrete layer 3 shall not be less than 15cm, and the concrete gradation shall not be less than C30. The concrete layer 3 covers most of the back area of ​​the reinforcing mesh 2 and the lining plate body 1, with a reserved area for the influence of the steel lining edge weld. The reserved area for the influence of the steel lining edge weld helps to prevent the impact of temperature rise during steel plate welding on the joint between the steel plate and the concrete.

[0025] Preferably, lifting lugs 5 are welded at appropriate positions on the rib plate 4, and the lifting lugs serve as lifting points for the component.

[0026] Preferably, connectors 6 are welded at appropriate positions on the rib plate 4, with the spacing between connectors 6 not exceeding 1*1.2m. Connectors 6 are used to connect internal tie rods or internal bracing steel bars.

[0027] Working principle and process:

[0028] 1) Insert steel bars into the reserved holes on the rib plate 4 on the back of the liner body 1 and tie them into a steel mesh 2;

[0029] 2) Erect a formwork in the area affected by the weld at the edge of the liner body 1;

[0030] 3) Weld lifting lugs 5 at appropriate positions on rib plate 4 to serve as lifting points for the component;

[0031] 4) Weld connectors 6 at appropriate positions on rib plate 4, with the spacing between connectors 6 not exceeding 1*1.2m;

[0032] 5) In the area not affected by the weld on the back of the lining plate body 1, pour a thin layer of concrete 3 with a gradation of not less than C30 and a thickness of not less than 15cm to improve the overall strength of the steel lining.
