Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a building pad component with pre-embedded hook reinforcement. Background Technology

[0002] In existing building construction, plastic or concrete spacers (hereinafter referred to as "building spacers") are usually used to control the minimum thickness of the concrete cover for reinforcing bars. During the installation process, building spacers need to be positioned and tied to the reinforcing bar cage with tie wire. This process is not only labor-intensive and inefficient, but the tied building spacers are also prone to loosening or displacement, leading to functional failure.

[0003] Hook bars, also known as tie bars, are steel reinforcement components used in reinforced concrete structures to maintain the position of steel bars and enhance the overall integrity of the steel reinforcement cage. Hook bars require tying to the steel reinforcement cage with wire during installation, which also presents the problems of large workload and low efficiency. Utility Model Content

[0004] To address the above problems, this utility model proposes a pre-embedded hook reinforcement building block assembly, which integrates the hook reinforcement and the building block, allowing the installation of the building block and the hook reinforcement to be combined into one step, resulting in higher construction efficiency.

[0005] This utility model is achieved through the following technical solution.

[0006] A pre-embedded hook reinforcement building pad assembly, characterized in that it comprises: hook reinforcement and pads connected to both ends of the hook reinforcement; The pad includes an inner pad in the shape of a disc and two outer pads; the two outer pads are coaxially and symmetrically arranged on the outside of the inner pad, so that the two outer pads and the inner pad form an annular pre-embedded groove, and the outer pads and the inner pads have snap-fit ​​grooves on the radius at the same position. The hook has symmetrically arranged annular hooks at both ends. The bottom of the hook has a snap-fit ​​interface that matches the snap-fit ​​groove. The hook is embedded in the pre-embedded groove of the pad and rotates to fit on the inner pad.

[0007] Preferably, the groove of the snap-fit ​​groove on the outer pad has a chamfered structure.

[0008] Preferably, the bottom of the snap-fit ​​groove is semi-circular, and a semi-circular metal gasket is fitted to the bottom of the snap-fit ​​groove.

[0009] Preferably, the inner and outer pads are made of rigid plastic or precast concrete.

[0010] More preferably, the pad is pre-formed as an integral part of an inner pad and an outer pad.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model can be prefabricated in batches in the factory according to different specifications according to construction needs, and can be flexibly matched with various concrete structures such as cast-in-place walls, floor slabs, beams and columns, foundations, and prefabricated components.

[0012] 2. In this utility model, the thickness of the protective layer is controlled by a disc-shaped pad and fixed and limited by a hook bar, which makes it less prone to loosening and displacement. In actual use, the thickness deviation of the protective layer is ≤±1.5 mm, which is far better than the traditional ±5 mm level and meets or exceeds the requirements of national building codes.

[0013] 3. This utility model integrates the hook reinforcement and the building pad, combining the two processes into one. It eliminates the need for binding wire; simply insert the positioning reinforcement into the bottom of the slot and rotate the pad to complete the installation, resulting in higher construction efficiency. In actual construction, this utility model can be completed independently by a single person on-site, with an average operation time of ≤10 seconds per group. Compared to the traditional method of installing the hook reinforcement and pad separately, which takes 50-60 seconds, efficiency is increased by approximately 80% or more, and the overall construction cycle is significantly shortened.

Detailed Implementation

[0016] The technical solutions in some embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided by the present invention are within the scope of protection of the present invention.

[0017] This embodiment provides a pre-embedded hook reinforcement building pad assembly. Please refer to [link / reference]. Figures 1 to 4 It includes: a hook 2, and pads 1 connected to both ends of the hook 2; wherein: The pad 1 includes an inner pad 101 in the shape of a disc and two outer pads 102; the two outer pads 102 are coaxially and symmetrically arranged outside the inner pad 101 so that the two outer pads 102 and the inner pad 101 enclose to form an annular pre-embedded groove 103, and the outer pads 102 and the inner pads 101 are provided with snap-fit ​​grooves 104 on the radius at the same position; The hook 2 has symmetrically arranged annular hooks 202 at both ends. The bottom of the hook 202 is provided with a snap-fit ​​interface 203 that cooperates with the snap-fit ​​groove 104. The hook 202 is embedded in the pre-embedded groove 103 of the pad 1 and rotates to fit on the inner pad 101. In the above structure, the diameter of the outer pad 102 can be determined according to the thickness of the reinforcing bar protective layer, and the diameter of the outer pad 102 is larger than that of the inner pad 101; the thickness of the inner pad 101 should be larger than the diameter of the hook 2, and the thickness of the outer pad 102 is not limited, as long as the strength and durability of the outer pad 102 are ensured and reasonably designed; the groove height of the snap-fit ​​groove 104 is the same as the diameter of the positioning rib being snapped in; the length and diameter of the hook 2 can be reasonably designed as needed, and the hook 2 is made of steel bars; the distance between the centers of the hook portions 202 at both ends of the hook 2 is slightly smaller than the distance between the positioning ribs that need to be connected at both ends of the hook 2; specifically, in this embodiment, the diameter of the outer pad 102 is 8 cm (the controlled thickness of the reinforcing bar protective layer is 4 cm), and the thickness of the inner pad 101 is 12 mm, so that the hook ribs 2 with a diameter of 6 mm to 12 mm can be smoothly embedded into the pre-embedded groove 103 and rotated and hooked on the inner pad 101, and the diameter of the inner pad 101 and the inner diameter of the hook portion 202 are 3 mm. cm; Based on the above structure, please refer to Figures 5-7 The following uses a cast-in-place wall as an example to further explain the usage method or working principle of this utility model: S1. Conduct a quality inspection on the building pad block assembly, including checking whether the pad block 1 is cracked, whether the slot of the snap-fit ​​groove 104 is damaged, and whether the hook rib 2 is deformed. Select building pad block assemblies with good quality for later use. S2. Rotate the pads 1 on both sides of the building pad assembly so that the snap-fit ​​grooves 104 of the pads 1 on both sides are in a vertically downward position, so as to align and connect with the insertion interface of the hook 202. S3. Align the snap-fit ​​grooves 104 of the left and right side pads 1 with the positioning ribs 302 on the left and right sides respectively and press them down so that the positioning ribs 302 on the left and right sides snap into the bottom of the snap-fit ​​grooves 104 of the left and right side pads 1. S4. Rotate the left and right pads 1 so that their locking grooves 104 point towards the center line of the wall, and make the angle between the locking grooves 104 and the center line of the wall approximately 45°. At this time, the locking grooves 104 of the two pads 1 are misaligned with the insertion interface 203 of the hook 202, and the positioning rib 302 is restricted within the locking groove 104 in the inner pad 101, thereby connecting the hook rib 2 between the positioning ribs 302 on both sides, and installing the pad 1 on the positioning rib 302; In the existing technology, both the hook reinforcement and the building pad need to be tied to the steel reinforcement skeleton with tie wire, and the installation is carried out in two separate steps. However, this utility model integrates the hook reinforcement and the building pad, combining the two processes into one. Moreover, it does not require the use of tie wire. The installation can be completed simply by inserting the positioning reinforcement into the bottom of the snap-fit ​​groove and rotating the pad, which results in higher construction efficiency.

[0018] Furthermore, in a preferred embodiment, the groove of the snap-fit ​​groove 104 on the outer pad 102 is a chamfered structure; with this structure, by setting the chamfer, the positioning rib can be more easily snapped into the snap-fit ​​groove 104.

[0019] Furthermore, in a preferred embodiment, the bottom of the snap-fit ​​groove 104 is semi-circular, and a semi-circular metal gasket 105 is fitted to the bottom of the snap-fit ​​groove 104; with this structure, the concentrated stress on the bottom of the snap-fit ​​groove 104 by the positioning rib can be reduced by the support of the metal gasket 105, so as to avoid cracking and damage of the gasket during use.

[0020] Furthermore, in a preferred embodiment, the inner pad 101 and the outer pad 102 are prefabricated from rigid plastic or concrete; preferably, the pad 1 is integrally prefabricated from the inner pad 101 and the outer pad 102.
