Description

Technical Field

[0001] This utility model relates to prefabricated hybrid beams, and in particular to a prefabricated assembled hybrid beam. Background Technology

[0002] Precast hybrid beams are composite beam structures that combine precast concrete components with steel structures (or other materials). This type of structure integrates the advantages of both steel and concrete, possessing the lightweight and high-strength characteristics of steel structures while enhancing overall stiffness, compressive strength, and durability through concrete.

[0003] When two precast hybrid beams need to span a large span together, connecting them can form a continuous beam, reducing mid-span bending moment and increasing load-bearing capacity. However, in existing technologies, precast hybrid beams are generally connected by connectors. During the connection process, the steel bars in the two precast hybrid beams need to be cut before being connected by connectors, making it difficult to maintain the continuity of the steel bars. This results in discontinuous stress transfer and lower structural strength. Utility Model Content

[0004] To address the problem in the prior art where connecting components make it difficult to maintain the continuity of reinforcing bars, leading to discontinuous stress transmission and reduced structural strength, this invention proposes a prefabricated assembled hybrid beam.

[0005] The technical solution of this utility model is as follows: it includes two connecting beams, a connecting section, and connecting reinforcing bars.

[0006] Two connecting beams are arranged opposite each other at intervals. Each connecting beam includes a precast concrete section and two steel joints. The precast concrete section extends in the left and right direction. The adjacent part of the two precast concrete sections is a pre-embedded part. The steel joints are pre-embedded in the pre-embedded part. The adjacent ends of the two steel joints are located outside the precast concrete section. A pouring gap is left between the two steel joints.

[0007] The connecting section is set at two adjacent steel section joints, and the connecting section is located within the pouring gap;

[0008] The pouring gap is used for concrete pouring;

[0009] The connecting steel bars are placed between the precast concrete sections, and the connecting steel bars pass through the two precast concrete sections in sequence;

[0010] The connecting section has a gap for the connecting reinforcing bars to pass through.

[0011] Preferably, the connecting section includes two embedded parts and a connector. The two embedded parts correspond one-to-one with two steel section joints. The embedded parts are fixedly connected to the corresponding steel section joints, and the embedded parts are provided with through holes for the connecting reinforcing bars to pass through.

[0012] The connector is positioned between two embedded parts, and the left and right ends of the connector are fixedly connected to the adjacent embedded parts respectively.

[0013] Preferably, the embedded part includes an embedded plate and a connecting plate. The embedded plate is connected to the steel section joint, and the connecting plate is fixedly connected to the embedded plate. The connecting plate is located outside the steel section joint, and two adjacent connecting plates are arranged opposite each other. The connecting plate is fixedly connected to the connecting part.

[0014] Preferably, the connector includes four angle steels, which are disposed between two adjacent connecting plates and spaced apart. The angle steels extend in the left-right direction, and both ends of the angle steels are fixedly connected to the adjacent connecting plates.

[0015] Preferably, the embedded plate has bolt connection holes, the steel joint has insertion holes, a connecting bolt is inserted into the insertion holes, and the connecting bolt is threadedly connected to the bolt connection holes.

[0016] Preferably, the top of the precast concrete segment is fixedly connected with multiple concrete segment flexible cables, and the multiple concrete segment flexible cables are arranged in an array at intervals.

[0017] The top of the steel joint is fixedly connected with multiple steel studs, which protrude from the top of the precast concrete section.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: This example aims to propose a prefabricated assembled hybrid beam.

[0025] according to Figures 1-2 As shown, it includes two connecting beams, a connecting section, and 5 connecting steel bars.

[0026] Two connecting beams are arranged opposite each other at intervals. The connecting beams include precast concrete sections 1 and two steel joints 2. In this embodiment, the steel joints 2 are selected from I-beams. The precast concrete sections 1 extend in the left and right direction. The adjacent parts of the two precast concrete sections 1 are embedded parts. The steel joints 2 are embedded in the embedded parts. The embedding method is that when the precast concrete section 1 is not formed, the steel joints 2 are inserted into the concrete section mold, and then the concrete is poured. After the concrete is formed, one end of the steel joint 2 is embedded in the precast concrete section 1. The adjacent ends of the two steel joints 2 are located outside the precast concrete section 1. A pouring gap is left between the two steel joints 2 for concrete pouring.

[0027] The connecting section is set at two adjacent steel section joints 2. The connecting section is located in the pouring gap. The connecting section includes two embedded parts 3 and a connector 4. The two embedded parts 3 correspond one-to-one with the two steel section joints 2. The embedded parts 3 are fixedly connected to the corresponding steel section joints 2. The embedded parts 3 are provided with through holes for the connecting steel bars 5 to pass through. The connector 4 is set between the two embedded parts 3. The left and right ends of the connector 4 are fixedly connected to the adjacent embedded parts 3 respectively.

[0028] The embedded part 3 includes an embedded plate 301 and a connecting plate 302. The embedded plate 301 is connected to the steel joint 2. The connecting plate 302 is fixedly connected to the embedded plate 301. The connecting plate 302 is located outside the steel joint 2. Two adjacent connecting plates 302 are arranged opposite each other. The connecting plate 302 is fixedly connected to the connecting part 4.

[0029] The connector 4 includes four angle steels, which are arranged between two adjacent connecting plates 302 and spaced apart. The angle steels extend in the left and right direction, and both ends of the angle steels are fixedly connected to the adjacent connecting plates 302. The fixing method in this embodiment is welding. The angle steels are easy to collect, and there are gaps between the angle steels to facilitate the passage of the connecting steel bars 5.

[0030] The embedded plate 301 has bolt connection holes, and the steel connector 2 has insertion holes. A connecting bolt 6 is inserted into the insertion holes, and the connecting bolt 6 is threadedly connected to the bolt connection holes, so that the connection can be made quickly through the connecting bolt 6.

[0031] Multiple concrete section flexible cables 7 are fixedly connected to the top of the precast concrete section 1. The multiple concrete section flexible cables 7 are arranged in an array at intervals. Multiple steel studs 8 are fixedly connected to the top of the steel joint 2. The steel studs 8 protrude from the top of the precast concrete section 1.

[0032] The connecting steel bars 5 are placed between the precast concrete sections 1, and the connecting steel bars 5 pass through the two precast concrete sections 1 in sequence.

[0033] After the two connecting beam hoisting devices are installed at their respective locations, concrete is poured during the pouring gap to connect the two connecting beams into one unit.

[0034] This allows for the rapid connection of two beams without cutting the reinforcing bars in the precast concrete section 1, thus preserving the continuity of the reinforcing bars, ensuring continuous stress transfer, and improving structural strength.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
