Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a fixing device for use in staircase protective layers. Background Technology

[0002] Staircase protective layers typically utilize spacers as fixing devices for the reinforcing steel. Spacers are commonly used in brick-concrete structures to fix the reinforcing steel, increasing the bearing area and relieving localized pressure. Commonly used spacers include concrete spacers and plastic spacers.

[0003] Plastic pads are easy to transport and store, and their use is unaffected by weather, making them widely used. Plastic pads are typically injection-molded as a single unit, with circumferentially arranged support feet on their surface to secure them and prevent rolling. However, because these support feet protrude from the surface, they are prone to deformation and damage, and once damaged, they cannot be repaired. Summary of the Invention

[0004] The purpose of this invention is to provide a fixing device for a staircase protective layer. The plastic pad adopts a modular design, and the raised support on the surface of the plastic pad is easy to replace and repair after damage. At the same time, it improves the deformation resistance of the plastic pad and makes the plastic pad less prone to damage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fixing device for a staircase protective layer, comprising: a pad body and an outer ring body. The pad body includes an inner ring body, an outer ring body, and reinforcing ribs. The inner ring body and the outer ring body are arranged concentrically and have notches along the radial direction, forming a snap-fit. Several reinforcing ribs are provided between the inner ring body and the outer ring body. A baffle extending into the inner ring body is provided within the notch. Several protruding support portions are provided on the surface of the outer ring body. Several connecting blocks are provided on the inner side of the outer ring body. The surface of the outer ring body is provided with slots corresponding to the positions of the connecting blocks. The connecting blocks are snapped into the slots. The outer ring body is fixedly installed on the outer ring body by screws.

[0006] As a further description of the above technical solution:

[0007] A stop is provided at the end of the baffle.

[0008] As a further description of the above technical solution:

[0009] The stop block is a cylindrical block.

[0010] As a further description of the above technical solution:

[0011] The connecting block is located on the back of the support.

[0012] As a further description of the above technical solution:

[0013] The connecting block has a "T" shaped structure and includes a first plate and a second plate. The first plate is fixedly installed on the back of the support and the second plate is fixedly installed on the bottom of the first plate. The second plate is snapped into the slot.

[0014] As a further description of the above technical solution:

[0015] The second plate is an arc-shaped plate.

[0016] As a further description of the above technical solution:

[0017] The second plate has symmetrically arranged curved surfaces at both ends.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. In this invention, the irregularly shaped anti-fall pad (i.e., fixing device) consists of two parts: the pad body and the outer ring body. The outer ring body is snapped into the pad body by a connecting block and further fixed by screws. The irregularly shaped anti-fall pad made of plastic adopts a modular design, and the raised support part on the surface of the plastic pad is easy to replace and repair if damaged.

[0020] 2. In this invention, a number of reinforcing ribs are provided between the inner ring and the outer ring of the pad body.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0029] Please see Figure 1-3 The present invention provides a technical solution: a fixing device for a staircase protective layer, comprising: a pad body 1 and an outer ring body 2. The pad body 1 includes an inner ring body 11, an outer ring body 12 and reinforcing ribs 13. The inner ring body 11 and the outer ring body 12 are arranged concentrically and have notches 14 in the radial direction. The notches 14 form a bayonet. A plurality of reinforcing ribs 13 are provided between the inner ring body 11 and the outer ring body 12. A baffle 15 extending into the inner ring body 11 is provided in the notch 14. A plurality of protruding support portions 21 are provided on the surface of the outer ring body 2. A plurality of connecting blocks 22 are provided on the inner side of the outer ring body 2. A slot 121 corresponding to the position of the connecting block 22 is provided on the surface of the outer ring body 12. The connecting block 22 is engaged in the slot 121. The outer ring body 2 is fixedly installed on the outer ring body 12 by screws 3.

[0030] The end of the baffle 15 is provided with a stop block 151, which is a cylindrical block that can effectively limit the insertion position of the reinforcing bar, fully position the reinforcing bar, and ensure the snap-fit ​​effect.

[0031] The connecting block 22 is located on the back of the support part 21, which effectively supports the protruding support part 21 and prevents the support part 21 from deforming.

[0032] The connecting block 22 has a "T" shaped structure. The connecting block 22 includes a first plate 221 and a second plate 222. The first plate 221 is fixedly installed on the back of the support part 21, and the second plate 222 is fixedly installed on the bottom of the first plate 221. The second plate 222 is snapped into the slot 121 to realize the detachable installation of the outer ring body 2.

[0033] The second plate 222 is an arc-shaped plate, which makes the thickness of the plate on both sides of the opening of the slot 121 uniform, ensuring the deformation resistance of the outer ring 12.

[0034] The second plate 222 has symmetrically arranged arc surfaces 2221 at both ends. On the one hand, it facilitates the insertion of the connecting block 22 into the slot 121. On the other hand, it makes the transition surface between the plate on both sides of the slot 121 opening and the outer ring 12 an arc-shaped transition surface, further improving the plate's resistance to deformation.

[0035] Working principle: When using the irregularly shaped anti-falling pad (i.e., fixing device), the reinforcing bar is inserted through the notch 14. The reinforcing bar is clamped between the baffle 15 and the inner ring 11, making installation convenient. The protruding support part 21 on the outer ring 2 abuts against the inner surface of the template to fix the pad and prevent it from rolling. The irregularly shaped anti-falling pad consists of two parts: the pad body 1 and the outer ring 2. The outer ring 2 is connected to the pad body 1 by the connecting block 22 and further fixed by screws 3. The plastic irregularly shaped anti-falling pad adopts a modular design, and the protruding support part on the surface of the plastic pad is easy to replace and repair if damaged. Several reinforcing ribs 13 are provided between the inner ring 11 and the outer ring 12 in the pad body 1. The connecting block 22 on the back of the outer ring 2 not only connects to the pad body 1 but also effectively supports the protruding support part 21, preventing the support part 21 from deforming. Therefore, it can effectively improve the deformation resistance of the plastic pad and make the plastic pad less prone to damage.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
