Description

Technical Field

[0001] The present application relates to the field of building construction, and specifically to a structure with reserved column reinforcement to prevent corrosion. Background Art

[0002] Currently, developers often adopt phased investment and rolling development to adapt to market changes, reduce upfront investment, mitigate investment risks, increase investment returns, and accelerate capital recovery. This development model requires full consideration of the structural connections between adjacent sections during the design phase. To ensure the reliability of these connections, reserved reinforcement is often used. Effectively ensuring the integrity of these reserved reinforcements is paramount.

[0003] The traditional method of protecting reserved steel bars is to pour concrete column heads. The early stages involve steel bar tying, formwork support, and concrete pouring, which are time-consuming and labor-intensive. The later stages of extending the reserved steel bars require breaking the concrete column heads and cleaning the concrete wrapped in the steel bars, which is time-consuming, labor-intensive, dusty, and pollutes the environment. The steel bars are disturbed, and the cleaning of the concrete wrapped in the steel bars is extremely difficult. Utility Model Content

[0004] The purpose of the utility model is to provide a structure for preventing column reinforcement from being rusted, to solve the shortcomings of traditional reinforcement protection methods, and to create a reinforcement corrosion-proof device that is simple in structure, easy to manufacture, has good reinforcement protection effect, is easy to dismantle, has low labor intensity, high construction efficiency, and the reserved reinforcement is undisturbed and has high positioning accuracy.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Further preferably, the sealing layer has a thickness of 50-60 mm and is cast by casting the same type of concrete as the original concrete structural column.

[0008] Furthermore, the diameter of the galvanized steel pipe is at least 30 mm wider than the reserved column reinforcement, the wall thickness is 1.5 to 3.0 mm, and the length is at least 50 mm longer than the reserved steel bar.

[0009] Furthermore, the length of the galvanized top cover is 50-100 mm.

[0010] Furthermore, the top surface elevation of the corrugated pipe is higher than the top surface elevation of the galvanized steel pipe.

[0011] More preferably, the number of the galvanized steel pipes is equal to the number of the reserved column reinforcements.

[0012] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0013] The steel bar rust-proof device of the utility model has a simple structure, simple and convenient construction, and is easy to operate. The materials involved are finished products or semi-finished products and do not require deep processing. The labor intensity requirement for operators is low, which greatly improves construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a schematic diagram of a structure with reserved column reinforcement to prevent corrosion for this application. DETAILED DESCRIPTION

[0015] In order to make the technical means, innovative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below.

[0016] The embodiments described herein are specific embodiments of the present invention and are used to illustrate the concept of the present invention. They are illustrative and exemplary and should not be construed as limiting the embodiments and scope of the present invention. In addition to the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the claims and the disclosure of the specification, including technical solutions that adopt any obvious substitutions and modifications to the embodiments described herein.

[0017] A structure with reserved column reinforcement to avoid corrosion, such as Figure 1 As shown, it includes a corrugated pipe 1 that is sleeved on the original column head, fine sand 5 poured into the corrugated pipe 1 and on the original concrete structure layer, a galvanized steel pipe 2 is sleeved on the reserved column reinforcement, a sealing layer is provided between the galvanized steel pipe 2 and the original structure layer, the top of the galvanized steel pipe 2 is threadedly sealed by a galvanized top cover 3, and a heat-free waterproof grease 4 is poured into the galvanized steel pipe 2.

[0018] The sealing layer thickness is 50~60mm, and it is cast by the same type of concrete as the original concrete structural column. The diameter of the galvanized steel pipe 2 is at least 30mm wider than the reserved column reinforcement, the wall thickness is 1.5~3.0mm, and the length is at least 50mm longer than the reserved steel bar. The length of the galvanized top cover 3 is 50~100mm. The top surface elevation of the corrugated pipe 1 is higher than the top surface elevation of the galvanized steel pipe 2. The number of galvanized steel pipes 2 is equal to the number of reserved column reinforcement.

[0019] The reserved column reinforcement in this application is equipped with a corrosion-resistant connector composed of a galvanized steel pipe and a heat-free waterproof grease. By filling the galvanized steel pipe with the heat-free waterproof grease, air and water in the casing are removed, providing a corrosion-free environment for the steel bar and ensuring that the steel bar is not corroded. The corrosion-resistant connector is equipped with a corrugated tube on the outside and filled with fine sand to form a "column head". This strengthens its anti-disturbance ability, ensures that the reserved steel bar is not affected by the fertilizer tank backfill, and guarantees the quality of the steel bar during subsequent structural construction. This steel bar protection device is assembled, which is easy to dismantle later without disturbing the steel bar.

[0020] The construction method is as follows: insert the reserved steel bars into the galvanized steel pipe, seal and fix the bottom of the galvanized steel pipe with 50mm thick concrete of the same grade as the structural column to ensure the stability of the galvanized steel pipe during subsequent operations; fill the galvanized steel pipe with heat-free waterproof grease, and use a finished funnel or a simple funnel made on site to complete the filling operation of the heat-free waterproof grease; install and tighten the threaded galvanized top cover on the top of the galvanized steel pipe; slowly insert the corrugated pipe from top to bottom on the outside of all galvanized steel pipes to avoid disturbing the galvanized steel pipe; pour fine sand into the inside of the corrugated pipe from the center of the pipe until the inside of the corrugated pipe is filled.

[0021] The parts not involved in the present invention are the same as the existing technology or can be implemented by using the existing technology.

[0022] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive.
