Description

Technical Field

[0001] The utility model belongs to the technical field of assembled building connection structures, and in particular relates to an assembled main and secondary beam connection structure. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] In prefabricated buildings, the main and secondary beam connection nodes are key assembly components and play an important role in the stability, safety and durability of the building structure.

[0004] The existing connection method of the main and secondary beam connection nodes of prefabricated buildings is to open a groove on the main beam, set a corresponding protrusion on the secondary beam, and then connect the protrusion and the groove together and then pour concrete to fix it. This connection method destroys the integrity of the main beam, causing the main beam to easily break at the groove during subsequent transportation. Even if the main beam does not break, the connection strength of the connection node after the main and secondary beams are connected is weak, which is not conducive to ensuring the overall stability and reliability of the prefabricated building.

[0005] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content

The two opposite side walls of the connecting groove have symmetrically arranged through holes, and the connecting head is provided with through holes corresponding to the through holes. The connecting head extends into the connecting groove and can pass through the through holes and the through holes at the same time by fasteners to fix the first connecting part and the second connecting part.

[0012] As a further optimized technical solution, the first embedded portion is a U-shaped structure enclosed by two side walls and a bottom wall, and the first connecting portion is fixed on one of the side walls.

[0013] As a further optimized technical solution, the connecting groove has a top opening and a side opening, the side opening is arranged on a side away from the first embedded part for allowing the connecting head to extend into the connecting groove, and the top opening is used for pouring the consolidation material.

[0014] As a further optimized technical solution, a plurality of anchor components are arranged in parallel between the two side walls of the U-shaped structure. The anchor components are arranged on a side close to the top opening of the U-shaped structure to increase the tensile strength of the U-shaped structure.

[0015] As a further optimized technical solution, the anchoring component is a screw rod, and both ends of the screw rod are fixedly connected to the two side walls of the U-shaped structure respectively.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0031] The utility model provides a connection structure of assembled main and secondary beams, which realizes the connection of the main and secondary beams by pre-embedding part of a first connection member in the main beam, pre-embedding part of a second connection member in the secondary beam, and then connecting part of the first connection member protruding from the main beam with the second connection member protruding from the secondary beam.

[0032] Please refer to Figure 1-4 , see Figure 1 The connection structure of the assembled primary and secondary beams includes a first connection member 1 and a second connection member 3 that can realize assembly connection.

[0033] See Figure 2 The first connecting member 1 includes a first embedded portion 1-1 and a first connecting portion 1-2 fixedly connected by welding. The first embedded portion 1-1 is used to be embedded inside the main beam 2 when the main beam 2 is prefabricated, and the first connecting portion 1-2 is exposed on the outside of the main beam 2 for connecting the secondary beam.

[0034] The first embedded part 1-1 is a U-shaped structure formed by two side walls and a bottom wall, and the first connecting part 1-2 is fixed on one of the side walls. In order to increase the tensile strength of the U-shaped structure, a plurality of anchoring components 1-5 are installed in parallel between the two side walls of the U-shaped structure, and the anchoring components 1-5 are arranged on a side close to the top opening 1-3-1 of the U-shaped structure.

[0035] In this embodiment, the anchoring member 1-5 is a screw with external threads. The threads on the outside of the screw can increase the contact area with the concrete during the main beam pouring process, thereby helping to strengthen the connection with the main beam. Threaded holes that match the anchoring members 1-5 are arranged on the two side walls of the U-shaped structure, and the screw is fixedly connected to the U-shaped structure by threaded connection. In other embodiments, the screw can also be welded to the U-shaped structure.

[0036] See Figure 3 , Figure 4 The second connecting member 3 includes a second embedded portion 3-1 and a second connecting portion 3-2 which are fixedly connected by welding. The second embedded portion 3-1 is used to be embedded inside the secondary beam 4 when the secondary beam 4 is prefabricated, and the second connecting portion 3-2 is exposed on the outside of the secondary beam 4 for connecting the main beam.

[0037] The second embedded part 3-1 is a cylindrical structure with a quadrilateral cross section formed by four steel plates, the cylindrical structure has an inner cavity, and the opening of the cylindrical structure is arranged at an end away from the second connecting part 3-2. In this way, when the second embedded part 3-1 is poured on the secondary beam, concrete will also flow into the inner cavity of the cylindrical structure, thereby increasing the bonding strength between the second embedded part 3-1 and the secondary beam. In other embodiments, the second embedded part 3-1 can also be a rod-shaped structure.

[0038] One end of the cylindrical structure opposite to the opening is fixedly connected to a fixing plate 3-5 by welding, and the second connecting portion 3-2 is fixedly connected to the second embedded portion 3-1 by the fixing plate 3-5.

[0039] One of the first connection part 1-2 and the second connection part 3-2 has a connection groove 1-3, and the other has a connection head 3-3 for extending into the connection groove 1-3. In this embodiment, the connection groove 1-3 is arranged on the first connection part 1-2, and the connection head 3-3 is arranged on the second connection part 3-2. In other embodiments, the connection groove 1-3 can also be arranged on the second connection part 3-2, and the connection head 3-3 is arranged on the first connection part 1-2.

[0040] The two opposite side walls of the connection groove 1-3 are provided with a plurality of symmetrically arranged perforations 1-4, and the connector 3-3 is provided with through holes 3-4 corresponding to the perforations 1-4. The connector 3-3 is inserted into the connection groove 1-3 and can pass through the fastener 5 through the perforation 1-4 and the through hole 3-4 at the same time to fix the first connection part 1-2 and the second connection part 3-2. In this embodiment, the fastener 5 is a screw, and the inner wall of the perforation 1-4 has a thread adapted to the fastener 5, and the through hole 3-4 is a light hole. When connecting the connection groove 1-3 and the connector 3-3, the connector 3-3 is first inserted into the connection groove 1-3, and then the fastener 5 is used to pass through the perforation 1-4 and the through hole 3-4 at the same time, so that the connection groove 1-3 and the connector 3-3 are fixedly connected. In other embodiments, the fastener 5 can also be a connecting pin, and after the connecting pin passes through the perforation 1-4 and the through hole 3-4 at the same time, the connecting pin is welded and fixed to the perforation 1-4.

[0041] In this embodiment, the connection groove 1-3 has a top opening 1-3-1 and a side opening 1-3-2. The side opening 1-3-2 is arranged at a side away from the first embedded part 1-1 for the connection head 3-3 to extend into the connection groove 1-3, and the top opening 1-3-1 is used for pouring a consolidation. After the connection head 3-3 is inserted into the connection groove 1-3 through the side opening 1-3-2, the fixing plate 3-5 just blocks the side opening 1-3-2. At this time, the connection groove 1-3 and the fixing plate 3-5 form a cavity with only the top opening 1-3-1. By pouring concrete into the cavity as a consolidation, the strength of the connection between the primary and secondary beams can be further improved.

[0042] In this embodiment, the connecting head 3-3 is an I-beam, which has two relatively parallel side panels 3-3-1 and a connecting plate 3-3-2 arranged between the two side panels 3-3-1. The width of the side panel 3-3-1 is smaller than the width of the top opening 1-3-1 of the connecting groove 1-3. The connecting plate 3-3-2 divides the space between the two side panels 3-3-1 into two accommodating grooves 3-3-3.

[0043] In order to facilitate pouring concrete into the receiving groove 3-3-3, after the connector 3-3 is inserted into the connecting groove 1-3, two pouring holes 3-6 are provided on the side plate 3-3-1 facing the top opening 1-3-1, and each pouring hole 3-6 corresponds to a receiving groove 3-3-3, and is used to pour concrete into the receiving groove 3-3-3 as a consolidation material. In other embodiments, the consolidation material may also be an adhesive or glue.

[0044] The working principle of this utility model:

[0045] During the processing of the main and secondary beams, the first embedded part 1-1 and the second embedded part 3-1 are placed in the mold for casting the main beam 2 and the secondary beam 4 respectively, and then the main beam 2 and the secondary beam 4 are cast. After the casting of the main beam 2 and the secondary beam 4 is completed, the first connecting member 1 is integrally fixedly connected to the main beam, and the second connecting member 3 is integrally fixedly connected to the secondary beam. In the subsequent assembly process, the connecting head 3-3 of the second connecting part 3-2 is first extended into the side opening 1-3-2 of the connecting groove 1-3, and the first connecting part 1-2 is fixedly connected to the second connecting part 3-2 by the fastener 5, and then concrete is poured into the connecting groove 1-3 through the top opening 1-3-1 to further strengthen the connection between the main and secondary beams.
