Description

Technical Field

[0001] The utility model relates to the technical field of concrete prefabricated components, in particular to an earthquake-resistant concrete prefabricated component. Background Art

[0002] Prefabricated concrete components are concrete parts of buildings or structures that are prefabricated in a factory and then assembled on the construction site. These components are the material foundation of industrialized construction and are widely used in both industrial and residential buildings.

[0003] Traditional precast concrete components have limitations in terms of seismic resistance, especially in earthquake-prone areas. Improving their seismic toughness is a pressing issue. Existing technologies primarily increase the amount of steel reinforcement to improve seismic performance. While this can enhance the structure's seismic resistance to a certain extent, it often significantly increases construction costs. Therefore, developing an economical and efficient seismic-resistant precast concrete component is of great significance. Utility Model Content

[0004] 1. Technical Problems Solved

[0005] The technical problem to be solved by the present invention is that the seismic performance of traditional prefabricated concrete components needs to be further improved. Improving the seismic performance simply by increasing the number of steel bars greatly increases the construction cost.

[0006] 2. Technical Solution

[0008] As an improvement, mutually intersecting reinforcement rods are provided between the support rods on both sides, and the intersections of the reinforcement rods, as well as the reinforcement rods and the support rods are fixed together by welding.

[0009] As an improvement, a plurality of third connecting rods are provided in the rectangular connecting frame and are arranged vertically and staggered with the first connecting rods and the second connecting rods, and the third connecting rods are evenly distributed in the rectangular connecting frame.

[0010] As an improvement, rubber shock-absorbing pads are provided at the top and bottom ends of the support rods at the four corners.

[0011] As an improvement, a plurality of groups of stress-bearing reinforcement bars are interspersed in the concrete prefabricated component body.

[0012] As an improvement, the rectangular connecting frame, support rod, first connecting rod, second connecting rod and third connecting rod are all made of steel, and the intersections of the rectangular connecting frame, support rod, first connecting rod, second connecting rod and third connecting rod are all welded.

[0013] 3. Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are:

[0015] 1. The rectangular connecting frame, support rods, reinforcement rods, first connecting rods, second connecting rods and third connecting rods are rationally designed. Since the second connecting rod is corrugated, it can enhance the seismic resistance of the component in multiple directions, and the vertical cross arrangement forms a network structure, which greatly improves the seismic resistance effect.

[0016] 2. The rubber shock-absorbing pads at the top and bottom corners can effectively absorb and disperse seismic energy, reduce the seismic response of the structure, and further help improve the seismic performance. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Combined with attachment Figure 1 , Attachment Figure 2 and attached Figure 3 A seismic-resistant concrete prefabricated component includes a concrete prefabricated component body 1, wherein the four corners of the top of the concrete prefabricated component body 1 are provided with hanging rings 2, a rectangular connecting frame 3 is provided inside the concrete prefabricated component body 1, and multiple groups of evenly distributed support rods 4 are provided between the rectangular connecting frames 3, a first connecting rod 6 is provided inside the rectangular connecting frame 3, and corrugated second connecting rods 7 are provided inside the rectangular connecting frame 3 and on both sides of the first connecting rod 6.

[0024] Through the above structure, using the rectangular connecting frame 3, the first connecting rod 6 and the second connecting rod 7, and multiple groups of support rods 4 arranged vertically, the overall vertical cross-arrangement forms a mesh structure, and the second connecting rod 7 is corrugated, which can enhance the seismic resistance of the component in multiple directions and greatly improve the seismic resistance effect.

[0025] Combined with attachment Figure 3 , reinforcing rods 5 that cross each other are provided between the support rods 4 on both sides, and the intersection points of the reinforcing rods 5 and the reinforcing rods 5 and the support rods 4 are fixed together by welding.

[0026] Through the above structure, the two side support rods 4 located on both sides can be firmly connected by using the reinforcement rod 5, and the overall stability can be further improved by welding them together.

[0027] Combined with attachment Figure 3 A plurality of third connecting rods 8 are provided in the rectangular connecting frame 3 and are arranged vertically and staggered with the first connecting rods 6 and the second connecting rods 7 . The third connecting rods 8 are evenly distributed in the rectangular connecting frame 3 .

[0028] Through the above structure, the third connecting rod 8 and the first connecting rod 6 and the second connecting rod 7 are all arranged vertically and staggered, and the overall network structure has a reasonable structural design.

[0029] Combined with attachment Figure 3 and attached Figure 4 The top and bottom ends of the support rods 4 at the four corners are provided with rubber shock-absorbing pads 9.

[0030] Through the above structure, the rubber shock-absorbing pads 9 at the four corners can effectively absorb and disperse seismic energy, reduce the seismic response of the structure, and further help improve the seismic resistance.

[0031] Combined with attachment Figure 1 and attached Figure 2 A plurality of groups of stress reinforcement bars 10 are interspersed in the concrete prefabricated component body 1 .

[0032] Through the above structure, multiple groups of stress-bearing bars 10 are interspersed and cooperated with other components, so that the prefabricated parts are stronger and the overall stability is further improved.

[0033] Combined with attachment Figure 3 The rectangular connecting frame 3, the support rod 4, the first connecting rod 6, the second connecting rod 7 and the third connecting rod 8 are all made of steel, and the intersections of the rectangular connecting frame 3, the support rod 4, the first connecting rod 6, the second connecting rod 7 and the third connecting rod 8 are all welded.

[0034] Through the above structure, the steel is tightly integrated with the concrete matrix, which further improves the overall strength and seismic resistance of the component. In addition, the intersections are welded to form a stable structure with a long service life.

[0035] When the utility model is implemented:

[0036] First, place the frame consisting of the welded rectangular connecting frame 3, support rod 4, first connecting rod 6, second connecting rod 7 and third connecting rod 8 directly in the casting mold, then pour concrete directly into the mold, and insert the lifting ring 2 on the top of the concrete to be solidified. Wait for the concrete to solidify and demold it directly from the mold to complete the production of reinforced concrete.

[0037] By using a rectangular connecting frame 3, a first connecting rod 6 and a second connecting rod 7, as well as multiple groups of vertically arranged support rods 4, the overall vertical cross-arrangement forms a mesh structure. In addition, the second connecting rod 7 is corrugated, which can enhance the seismic resistance of the component in multiple directions and greatly improve the seismic resistance effect.

[0038] Then, the rubber shock-absorbing pads 9 at the four corners can effectively absorb and disperse seismic energy, reduce the seismic response of the structure, and further help improve the seismic performance. The overall structural design is reasonable, there is no need to increase the number of steel bars, and the overall construction cost is low.
