Description

Technical Field

[0001] This utility model relates to the field of prefabricated building components, and more specifically, to a high-strength prefabricated component. Background Technology

[0002] Precast components refer to steel, wood, or concrete building components that are prefabricated in a factory or on-site, encompassing types such as concrete components, bridge slabs, and tunnel slabs. Precast components are building parts that are prefabricated in a factory and then transported to the construction site for assembly, offering advantages such as high construction efficiency, controllable quality, and environmental friendliness.

[0003] Currently, in construction engineering, especially in high-rise buildings, large commercial complexes, and buildings in earthquake-prone areas, extremely high requirements are placed on the shear resistance performance of precast components. Most existing precast components are cast with a single layer of shear reinforcement, resulting in relatively limited overall shear resistance and strength, as well as relatively poor internal structural stability. Therefore, it is necessary to propose a high-strength precast component to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-strength precast component, which aims to improve the problem that most existing precast components are cast with a single layer of shear reinforcement, resulting in relatively limited overall shear strength and overall strength, as well as relatively poor internal structural stability.

[0005] This utility model is implemented as follows: This utility model provides a high-strength pre-component, including a pre-component structure and a reinforcing structure.

[0006] The pre-component structure includes a pre-component body and a lifting ring, the lifting ring being cast and fixed to the surface of the pre-component body; the reinforcing structure includes two shear reinforcement layers, connectors, and a metal mesh layer, the two shear reinforcement layers being fixed together by the connectors, the metal mesh layer being fixed to the surface of the shear reinforcement layers, and the two shear reinforcement layers being cast inside the pre-component body.

[0007] In one embodiment of this utility model, glass fiber and shear-resistant gel filler are added inside the pre-component body.

[0008] In one embodiment of the present invention, a tenon and mortise protrusion is formed on one side of the pre-component body, and a tenon and mortise groove matching the tenon and mortise protrusion is fixed on the other side of the pre-component body.

[0009] In one embodiment of this utility model, two mortise and tenon protrusions and two mortise and tenon grooves are provided, and the cross-sections of the mortise and tenon protrusions and the mortise and tenon grooves are trapezoidal.

[0010] In one embodiment of this utility model, the shear-strengthening layer includes a plurality of transverse reinforcing ribs and a plurality of longitudinal reinforcing ribs, wherein the plurality of transverse reinforcing ribs and the plurality of longitudinal reinforcing ribs are fixed perpendicularly to each other.

[0011] In one embodiment of this utility model, the connector includes a plurality of transverse triangular ribs and a plurality of longitudinal triangular ribs, wherein the plurality of transverse triangular ribs are fixed between the transverse reinforcing ribs and the plurality of longitudinal triangular ribs are fixed between the longitudinal reinforcing ribs.

[0012] In one embodiment of this utility model, the metal mesh layer includes a plurality of transverse metal wires and a plurality of longitudinal metal wires, wherein the plurality of transverse metal wires and the plurality of longitudinal metal wires are interlaced and fixed perpendicularly to each other.

[0013] The beneficial effects of this utility model are as follows: The high-strength precast component obtained by the above design can increase the splicing area by setting two trapezoidal tenon and mortise protrusions and tenon and mortise grooves, thereby making the splicing more stable. By setting double-layer transverse and longitudinal reinforcing ribs, as well as transverse and longitudinal triangular ribs for connecting the double-layer shear-strengthening layers, it can be made into a whole. In this way, after being poured into the main body of the precast component, a two-way tensile system can be formed, which enhances the tensile strength, effectively suppresses reflective cracks and settlement deformation, prevents crack propagation, improves the overall strength and stability of the precast component, and makes it more stable and reliable in use.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0018] Please see Figures 1-5 This utility model provides a technical solution: a high-strength pre-component, comprising a pre-component structure 100 and a reinforcing structure 200.

[0019] Please see Figures 1-4 The pre-component structure 100 includes a pre-component body 110 and a lifting ring 120, with the lifting ring 120 cast and fixed to the surface of the pre-component body 110.

[0020] The interior of the precast component 110 is filled with glass fiber and shear-resistant gel filler. Glass fiber is a lightweight, high-strength material. After being added, it can form a mesh-like structure, which makes the stress inside the concrete more evenly distributed and prevents the concrete from cracking and breaking. Glass fiber has good corrosion resistance and durability, which can effectively prevent the concrete from being eroded and weathered by chemicals, thus making the concrete more durable.

[0021] One side of the pre-component body 110 has a tenon-and-mortise protrusion 111, and the other side of the pre-component body 110 is fixed with a tenon-and-mortise groove 112 that matches the tenon-and-mortise protrusion 111. There are two tenon-and-mortise protrusions 111 and two tenon-and-mortise grooves 112. The cross-section of the tenon-and-mortise protrusions 111 and the tenon-and-mortise grooves 112 is trapezoidal. The fit between the tenon-and-mortise protrusions 111 and the tenon-and-mortise grooves 112 can increase the fit area, which is conducive to a more stable and firm assembly.

[0022] Please see Figures 1-5The reinforced structure 200 includes two shear reinforcement layers 210, connectors 220 and a metal mesh layer 230. The two shear reinforcement layers 210 are fixed together by connectors 220, and the metal mesh layer 230 is fixed to the surface of the shear reinforcement layer 210. The two shear reinforcement layers 210 are cast inside the precast component body 110.

[0023] The shear reinforcement layer 210 includes several transverse stiffeners 211 and several longitudinal stiffeners 212, with the transverse stiffeners 211 and the longitudinal stiffeners 212 fixed perpendicularly to each other. The connector 220 includes several transverse triangular ribs 221 and several longitudinal triangular ribs 222, with the transverse triangular ribs 221 fixed between the transverse stiffeners 211 and the longitudinal triangular ribs 222 fixed between the longitudinal stiffeners 212. Here, the two shear reinforcement layers 210 are connected together by the transverse triangular ribs 221 and the longitudinal triangular ribs 222, which can form a two-way tensile system, enhance tensile strength, effectively suppress reflective cracks and settlement deformation, and improve the overall stability of the precast component. The metal mesh layer 230 includes several transverse metal wires 231 and several longitudinal metal wires 232. All of the transverse metal wires 231 and longitudinal metal wires 232 are steel wires. The transverse metal wires 231 and longitudinal metal wires 232 are interlaced and fixed vertically. The arrangement of the metal mesh layer 230 can help the concrete to better fit with the shear reinforcement layer 210 and the connector 220, thereby increasing the overall stability.

[0024] Specifically, the structural principle of this high-strength precast component is as follows: the addition of two trapezoidal tenon and mortise protrusions 111 and tenon and mortise grooves 112 increases the splicing area, making the splicing more stable. The addition of double-layer transverse reinforcing ribs 211 and longitudinal reinforcing ribs 212, as well as transverse triangular ribs 221 and longitudinal triangular ribs 222 for connecting the double-layer shear-strengthening layer 210, makes it a whole. After being poured into the precast component body 110, it can form a two-way tensile system, enhancing tensile strength, effectively suppressing reflective cracks and settlement deformation, preventing crack propagation, improving the overall strength and stability of the precast component, and making it more stable and reliable in use.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
