Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a quick-installation roller-type rebar protective layer controller. Background Technology

[0002] In the construction industry, during the main structural construction phase, reinforcing steel bars play a crucial role as the structural skeleton. Construction teams are required to fix the steel bars in place according to the drawings. Precise control of the concrete cover thickness directly affects the structural durability and safety. Traditional methods, such as using precast spacers or manual tying for positioning, have the following drawbacks:

[0003] 1. Low installation efficiency: Each pad needs to be tied and fixed with steel wire, which is time-consuming and labor-intensive;

[0004] 2. Insufficient precision: Manual operation can easily lead to deviations in the thickness of the protective layer;

[0005] 3. Poor stability: It is prone to displacement during vibration or concrete pouring. Summary of the Invention

[0006] To address the aforementioned problems, this invention discloses a quick-installation roller-type rebar protective layer controller, which can be quickly installed and fixed, and is characterized by its resistance to displacement.

[0007] The specific plan is as follows:

[0008] A quick-installation roller-type rebar protective layer controller is characterized by comprising a disc body and an insert block. The disc body has a hole in the middle for fixing the rebar, and a strip-shaped insertion hole communicating with the hole is opened radially on the side. The strip-shaped insertion hole has symmetrically arranged slots on both sides in the middle. The insert block is a strip-shaped structure adapted to the strip-shaped insertion hole, with its upper end being an arc surface adapted to the rebar, and symmetrically arranged on both sides with the lower end inclined outwards. The slots are used to engage in the slots.

[0009] Furthermore, the insert and the clip are integrally molded plastic or soft metal parts.

[0010] Furthermore, the card strip is a flexible component that can be bent and recover.

[0011] The beneficial effects of this invention are as follows: This invention can achieve rapid installation and positioning preparation, and the thickness of the protective layer is controlled to be the same in all directions by means of the disc body; in addition, this invention has a fast installation speed, can realize prefabricated installation, and can be prefabricated in the factory for mass production, and has a broad market prospect.

[0017] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] As shown in the figure, the present invention provides a quick-installation roller-type rebar protective layer controller, including a disc body 1 and an insert block 2. The disc body 1 has a hole 4 in the middle for fixing the rebar, and a strip-shaped insertion hole communicating with the hole 4 is opened radially on the side. The two sides of the strip-shaped insertion hole are symmetrically provided with slots in the middle. The insert block 2 is a strip-shaped structure adapted to the strip-shaped insertion hole. Its upper end is an arc surface adapted to the rebar, and the two sides are symmetrically provided with a locking strip 3 with the lower end inclined outward. The locking strip 3 is used to lock into the slot.

[0019] In this embodiment, the insert 2 and the clip 3 are integrally molded plastic or soft metal parts.

[0020] In this embodiment, the card strip 3 is a flexible component that can be bent and recover.

[0021] The controller of this invention can be fixed to horizontal or vertical reinforcing bars, and can be made with circular rollers of different diameters according to different thickness requirements. Furthermore, the socket-type interface design effectively prevents it from falling off due to vibration during construction.

[0022] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
