Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a concrete column reinforcement structure. Background Art

[0002] Temporary concrete columns are often used in the construction of underground structures such as underground stations. These temporary concrete columns are often cast into piles by ground rotary drilling. The structural strength is low. In addition, they are often subject to equipment collisions and blasting operations during the subsequent construction process. Therefore, these temporary concrete columns often experience structural deformation and cracking during the construction process, affecting the safety of subsequent construction. At present, when concrete columns are damaged, they are often dealt with by adding piles or reducing the load. The method of adding piles is cumbersome and time-consuming, and has a greater impact on the construction period, while the method of reducing the load is more difficult to control. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art and to provide a concrete column reinforcement structure which is convenient to construct and saves time.

[0004] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0005] A concrete column reinforcement structure, comprising:

[0006] A plurality of casings are separated, assembled and fixed together to form an annular casing surrounding the outside of the concrete column, with a gap between the inner wall of the casing and the outer wall of the concrete column;

[0007] The concrete filling body is poured between the casing and the concrete column.

[0008] Preferably, the number of the casing parts is two and both parts have semicircular cross-sections.

[0009] Preferably, the casing body is a steel body.

[0010] Preferably, the casings are separately welded and fixed together.

[0011] Preferably, it also includes reinforcing steel bars tied outside the concrete column and located inside the casing.

[0012] Preferably, the side edge of each of the casing segments is stepped, and the joining sides of two adjacent casing segments are matched with each other.

[0013] Preferably, a reinforcement rope is tied around the outer circumference of the casing.

[0014] Preferably, it further comprises a bottom plate, which is fixed to the bottom of the casing and is used to close the opening at the bottom of the casing.

[0015] The beneficial effect of the utility model is that when the concrete column is damaged, the concrete column reinforcement structure only needs to splice and fix the casing parts outside the damaged part, and then pour concrete between the casing and the concrete column to form a concrete filling body, so that the damaged concrete column can be quickly reinforced. The construction is convenient and time-saving, easier to control, and helps to reduce delays in the construction period. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0021] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0022] Reference Figure 1 The preferred embodiment of the utility model is a concrete column reinforcement structure, comprising: a plurality of casing parts, which are assembled and fixed together to form an annular casing 10 surrounding the outside of a concrete column 30, with a gap between the inner wall of the casing 10 and the outer wall of the concrete column 30; and a concrete filling body 20, which is cast between the casing 10 and the concrete column 30. In the concrete column reinforcement structure, when the concrete column 30 is damaged, it is only necessary to assemble and fix the casing parts outside the damaged part, and then pour concrete between the casing 10 and the concrete column 30 to form the concrete filling body 20, so that the damaged concrete column 30 can be quickly reinforced, the construction is convenient and time-saving, and it is easier to control, which helps to reduce the delay of the construction period.

[0023] As a preferred embodiment of the utility model, it may also have the following additional technical features:

[0024] In this embodiment, the number of casing segments is two and the cross-sections are both semicircular, which is convenient for processing, manufacturing and splicing. In application, the two casing segments can be obtained by directly selecting existing cylindrical materials for cutting, or each casing segment can be formed by casting, etc. In other embodiments, the number of casing segments can also be selected as three, four or other arbitrary numbers, and is not limited thereto.

[0025] In this embodiment, the casing body is a steel body, which is easy to obtain and has a high structural strength, which is conducive to ensuring the load-bearing capacity of the reinforced concrete column 30. In other embodiments, the casing body can also be made of other suitable materials as needed, but is not limited to this. In this embodiment, each casing body is welded and fixed together, which is firmly connected, not easy to damage, and easy to construct. In other embodiments, each casing body can also be fixed by other suitable methods such as screws and rivets, but is not limited to this.

[0026] In this embodiment, reinforcing steel bars are also included which are tied to the outside of the concrete column 30 and located inside the casing 10 , which is beneficial to improving the structural strength of the concrete filling body 20 and the firmness of the connection with the concrete column 30 , thereby ensuring the reinforcement effect of the concrete column 30 .

[0027] In this embodiment, the side edges of each casing segment are stepped, and the joint sides of two adjacent casing segments are adapted to each other, which can improve the firmness of the joint fixation of each casing segment and help prevent leakage and damage to the casing 10 when pouring the concrete filling body 20.

[0028] In this embodiment, a reinforcement rope is tied around the outer circumference of the casing 10, which can further prevent the casing 10 from being damaged or loosened. The reinforcement rope can be made of common construction materials such as steel wire.

[0029] In this embodiment, a bottom plate is also included, which is fixed to the bottom of the casing 10 and is used to close the opening at the bottom of the casing 10 to facilitate the pouring of the concrete filling body 20. The bottom plate can be made of common materials such as steel plates and can be fixed to the bottom of the casing 10 by common methods such as welding and bundling.
