Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a protective layer thickness control device for a reinforced concrete vertical component and a construction method thereof. Background Art

[0002] In concrete structures, reinforced concrete is a composite material composed of two different materials, steel bars and concrete. The good bonding performance of the two materials is the basis for their joint work. The requirements for the concrete cover from the perspective of steel bar bonding and anchoring are to ensure that the steel bars and the surrounding concrete can work together, and that the steel bars can fully exert the strength required for calculation, and meet the requirements of durability and fire resistance. However, in the actual construction process, the thickness of the cover is often difficult to guarantee due to the influence of materials, processes, and awareness of operators.

[0003] Currently, pads are installed on the outside of the steel bars of the concrete structure to ensure the thickness of the concrete protective layer. However, such pads are easily displaced after installation and cannot effectively ensure the thickness of the concrete protective layer. Summary of the invention

[0004] In order to overcome the defects of the prior art, a protective layer thickness control device for reinforced concrete vertical components and a construction method thereof are provided to solve the problem that the existing method of ensuring the thickness of the concrete protective layer by pads is easy to shift and the thickness of the concrete protective layer cannot be well determined.

[0005] In order to achieve the above object, a protective layer thickness control device for a reinforced concrete vertical member is provided, comprising:

[0006] Two inner arc strips for sleeve-mounting the vertical main reinforcement of the vertical member, wherein the inner arc surfaces of the two inner arc strips are arranged opposite to each other;

[0007] A tie rod assembly with adjustable length, the tie rod assembly being connected between the ends of the two inner arc strips;

[0008] An outer arc bar is used to support the inner side of the formwork of the vertical component and is arranged on the outer side of the outer arc surface of the inner arc bar. The outer arc bar is arranged concentrically with the inner arc bar. The distance from the inner arc surface of the inner arc bar to the outer arc surface of the outer arc bar is adapted to the thickness of the concrete protective layer of the vertical component. A support plate is connected between the outer arc bar and the inner arc bar.

[0009] Furthermore, the inner arc strip and the outer arc strip are respectively semicircular.

[0010] Furthermore, the pull rod assembly includes:

[0011] A socket sleeve connected to one end of an inner arc strip;

[0012] A plug-in rod is connected to one end of the other inner arc strip, and one end of the plug-in rod is detachably inserted into the socket sleeve.

[0013] Furthermore, one end of the socket sleeve away from the inner arc strip is rotatably connected to a threaded sleeve, the threaded sleeve is coaxially arranged with the socket sleeve, one end of the plug rod is formed with an external thread, and one end of the plug rod is screwed into the threaded sleeve.

[0014] Furthermore, the support plate is fan-shaped.

[0015] The present invention provides a construction method of a protective layer thickness control device for a reinforced concrete vertical member, comprising the following steps:

[0016] The two inner arc strips of the protective layer thickness control devices of the plurality of reinforced concrete vertical components are respectively sleeved on the outside of the two vertical main bars of the vertical components, so that the protective layer thickness control devices of the plurality of reinforced concrete vertical components are arranged at intervals along the circumferential direction of the steel structure of the vertical components;

[0017] Adjust the length of the tie rod assembly, and tie the tie rod assembly between the ends of the two inner arc strips;

[0018] A formwork is set up on the outer side of the steel structure so that the outer arc strip is supported on the inner side of the formwork of the vertical member.

[0019] The beneficial effect of the present invention is that the protective layer thickness control device for reinforced concrete vertical components of the present invention has the ability to be quickly installed and put into use. The device is fixed to the vertical main reinforcement of the vertical component by a tie assembly. Two vertical main reinforcements at the corners of the steel structure of the vertical component can be selected as the objects to be connected by the device. A device is installed at each of the four corners of the steel structure, and each side will have two outer arc strips in contact with the formwork. The protective layer thickness of the vertical component in the plane is fully guaranteed, thereby ensuring the casting quality of the vertical concrete component, avoiding quality defects such as exposed reinforcement and rust due to insufficient protective layer thickness, better meeting the needs of the construction site, and can be widely used in major construction sites.

[0020] The protective layer thickness control device for reinforced concrete vertical components of the present invention reduces the loss of materials and labor caused by repairing problems such as exposed reinforcement and rust caused by insufficient thickness of the concrete protective layer. Rust removal requires the use of chemical agents, and reducing their use is in line with the green environmental protection concept of sustainable development. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The length of the tie rod assembly 2 is adjustable. The tie rod assembly 2 is connected between the ends of the two inner arc bars 1. In this embodiment, the tie rod assembly 2 is connected between the two ends of the two inner arc bars 1, respectively.

[0033] The outer arc bar 3 is used to support the inner side of the formwork of the vertical member. The outer arc bar 3 is arranged outside the outer arc surface of the inner arc bar 1. The outer arc bar 3 is arranged concentrically with the inner arc bar 1. The distance from the inner arc surface of the inner arc bar 1 to the outer arc surface of the outer arc bar 3 is adapted to the thickness of the concrete protective layer of the vertical member. A support plate 21 is connected between the outer arc bar 3 and the inner arc bar 1.

[0034] In this embodiment, the inner arc strip 1 and the outer arc strip 3 are both semicircular.

[0035] As a preferred implementation, the tie rod assembly 2 includes: a socket sleeve 21 and a splice rod 22 .

[0036] The socket sleeve 21 is connected to one end of an inner arc strip 1. The plug rod 22 is connected to one end of another inner arc strip 1. One end of the plug rod 22 is detachably inserted into the socket sleeve 21.

[0037] In this embodiment, the end of the socket sleeve 21 away from the inner arc strip 1 is rotatably connected to the threaded sleeve 23. The threaded sleeve 23 is coaxially arranged with the socket sleeve 21. One end of the plug rod 22 is formed with an external thread. One end of the plug rod 22 is screwed into the threaded sleeve 23.

[0042] S3. Set up a formwork on the outside of the steel structure 4 so that the outer arc strip 3 is supported on the inner side of the formwork of the vertical member.

[0043] In this embodiment, the inner arc strip, the support plate and the outer arc strip are integrally formed, which is the main body of the protective layer thickness control device for reinforced concrete vertical components of the present invention, and is specifically made of aluminum alloy.

Two vertical main reinforcements at the corners of the reinforcement structure of the vertical component can be selected as objects for connection of the device. A device is installed at each of the four corners of the reinforcement structure, and each side will have two outer arc strips in contact with the formwork. The protective layer thickness of the vertical component in the plane is fully guaranteed, thereby ensuring the casting quality of the vertical concrete component, avoiding quality defects such as exposed reinforcement and rusting due to insufficient protective layer thickness, better meeting the needs of the construction site, and can be widely used in major construction sites.
