Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to an environmentally friendly reinforced concrete protective pad for roof slabs. Background Technology

[0002] To protect the reinforcing steel in concrete from corrosion, the thickness of the concrete at the steel reinforcement is designed appropriately during construction. The main method for controlling the thickness of the concrete cover is to tie or pre-install spacers on the stirrups outside the steel reinforcement cage, and then erect the formwork after the steel reinforcement cage is tied. These spacers maintain the distance between the steel reinforcement and the formwork, thus ensuring the desired concrete cover thickness is achieved. Currently, the most commonly used spacers are concrete spacers, which have advantages such as a similar coefficient of linear expansion to concrete and good economic efficiency. To facilitate the installation of spacers, Chinese patent CN216196030U discloses a concrete reinforcement protective layer spacer with fasteners. This involves creating slots in the spacer body, with fasteners fitting within the slots. However, this patent has drawbacks: the fastener structure is overly complex, significantly increasing the manufacturing cost of the spacer. Furthermore, the complex structure also makes installation of the fasteners inconvenient. Utility Model Content

The pad body has a through hole at its axial center and an installation groove on its upper surface. The outer periphery of the pad body has a slot that communicates with both the through hole and the installation groove radially inward. The locking block comprises a locking block body and a connector. The locking block body is slidably disposed in the installation groove, and at least partially extends into the slot. The locking block body is fixedly connected to the pad body via the connector.

[0019] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0020] See Figure 1-3In one embodiment of this utility model, an environmentally friendly reinforced concrete protective pad for roof slabs includes: a pad body 1 and a locking block 2. The pad body 1 is formed by concrete casting. A through hole for inserting a reinforcing bar is provided at the axial center of the pad body 1. An installation groove 11 adapted to the size of the locking block 2 is provided on the upper surface of the pad body 1. The installation groove 11 has a fan-shaped structure and is coaxial with the through hole. A slot 12 communicating with the through hole and the installation groove 11 is provided radially inward from the outer periphery of the pad body 1. The locking block 2 includes a locking block body 21. The locking block body 21 has an arc-shaped plate structure and is slidably disposed in the installation groove 11. The inner arc radius of the locking block body 21 is related to the through hole. With the same radius, the outer arc surface of the locking block body 21 is slidably connected to the side wall of the mounting groove 11. That is to say, the size of the locking block body 21 is smaller than the size of the mounting groove 1. This ensures that the locking block body 21 can slide around the axis of the pad body 1 within the mounting groove 11. In use, it is only necessary to ensure that the locking block body 21 extends into the slot 12. By reducing the width of the slot 12, the reinforcing bar can be limited, preventing the reinforcing bar from sliding out of the slot 12. In addition, the locking block 2 also includes a connector. The locking block body 21 is fixed to the pad body 1 through the connector to prevent the locking block 2 from slipping off. Under the limitation of the locking block 2, the concrete protective pad can be firmly fixed to the reinforcing bar.

[0021] The connector is a steel pin 22, which is embedded in the block body 21, and both ends of the pin 22 extend outside the block body 21. In this embodiment, the pin 22 is curved, and the pin 22 and the block body 21 have the same axis, that is, the pin 22 and the block body 21 have the same length direction. In practice, the block 2 can be made by concrete casting. During casting, the pin 22 is placed horizontally in the mold beforehand. After the block 2 is cured, the pin 22 and the block body 21 become one. In this configuration, the pin 22 acts as the skeleton of the block 2, which can improve the overall strength of the block 2 and ensure the quality of the concrete protective pad.

[0022] In one embodiment, in order to reduce costs and increase efficiency, the pin 22 can also be made of concrete, and the block 2 can also be integrally formed by casting. The pin 22 can be located at one end of the length direction of the block body 21.

[0023] The inner wall of the mounting groove 11 is provided with a socket 13 for insertion and engagement with the pin 22. During installation, the pad body 1 can be first placed on the reinforcing bar, then the locking block 2 can be installed in the mounting groove 11, and finally the locking block 2 can be rotated so that one end of the pin 22 is inserted into the socket 13 to complete the fixing of the protective pad. The whole process is convenient and quick. At the same time, since the overall structure of the protective pad is simple and easy to manufacture, the production cost can be greatly reduced.

[0024] In one embodiment, the mounting slot 11 can also be a square slot, which can be adjusted according to production needs when the card block 2 is adapted to the mounting slot 11.

[0025] Furthermore, the outer end face of the card block body 21 is flush with the end face of the pad block body 1, improving the overall integrity of the protective pad block.

[0026] In one embodiment, the slot 12 is a gradually expanding groove in the direction away from the perforation. This design has the advantage of facilitating the installation of the pad body 1 on the reinforcing bar.

[0027] In one embodiment, the outer edge of the pad body 1 is provided with anti-slip grooves, which can further ensure the stability between the pad and the reinforcing bar after installation.

[0028] This technical solution involves creating interconnected mounting grooves and slots on the ring-shaped pad body. The slots are used for rebar installation, and the mounting grooves are equipped with sliding locking blocks. Each locking block has a pin, and the pad body has a socket that engages with the pin. After the pad body is installed on the rebar, the pin can be inserted into the socket by sliding the locking blocks to complete the installation process. The installation process is convenient and quick. Furthermore, the overall structure of the protective pad is simple and easy to manufacture, which can greatly reduce production costs.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
