Embodiment 1

[0032] This embodiment provides a beam structure, such as figure 1 As shown, in a preferred embodiment of the present invention, it includes a rectangular beam body 10, the middle part of the beam body 10 has a through hole arranged along its length direction, and the top of the beam body 10 has a top part arranged along its length direction. The opening 11b, the top opening 11b communicates with the through hole, the beam body 10 also has a lower surface 12 and two side surfaces 13, the lower surface 12 is opposite to the top opening 11b. The beam body 10 is fixed with at least one connecting plate 15 that fixes the opposite sides of the top opening 11b together. The connecting plate 15 and the beam body 10 are separately arranged and fixed together. The area 11b is the pouring hole 11a. When the number of connecting plates 15 is two or more, the connecting plates 15 are arranged at intervals along the length direction of the beam body 10 .

Embodiment 2

[0041] The structural principle of this embodiment is basically the same as that of Embodiment 1, the difference is that, as image 3 As shown, in this embodiment, both side surfaces 13 of the beam body 10 are provided with a plurality of communication holes 13 a communicating with the inside of the beam body 10 . Therefore, when concrete is poured, the concrete inside the crossbeam flows out from the communicating hole 13a, and the outflowing concrete is bonded to the wall panels on both sides, and the connection is stronger.

Abstract

The invention provides a cross beam structure which comprises a rectangular cross beam body. A through hole formed in the length direction of the cross beam body in a penetrating manner is formed in the middle portion of the cross beam body. A top opening communicating with the through hole and formed in the length direction of the cross beam body in a penetrating manner is formed in the cross beam body. A connecting plate used for fixedly connecting the opposite two faces of the top opening together is fixedly connected to the cross beam body. The connecting plate and the cross beam body arearranged in a split manner and are fixedly connected. The area, besides the connecting plate, of the top opening is a pouring hole. The area, besides the connecting plate, of the top opening is the pouring hole, concrete is poured into a cross beam from the pouring hole, the opposite two faces at the top opening of the cross beam body are fixedly connected with the connecting plate, and thereforethe phenomenon that the two sides of the cross beam body are deformed due to concrete deformation after pouring of the concrete is prevented. The cross beam structure is simple in structure and is adopted as a whole structure, installation is convenient, and the installation efficiency is high. Necking-down structures are arranged at the two ends of the cross beam body of the cross beam structure,the cross beam is connected with a joint through the necking-down structures, and due to the connecting manner of the necking-down structures, installation is fast.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a beam structure. Background technique [0002] The mortise and tenon joint is a commonly used connection form in ancient Chinese architectural structures. The structure uses wood, bricks and tiles as the main building materials, and the wood frame structure as the main structural method. It is constructed of main components such as columns, beams, and purlins, and the joints between each component are matched with mortise and mortise. [0003] Since the reform and opening up, with the rapid development of my country's economy, the application of steel structure has become more and more extensive, and it is playing an increasingly important role in construction engineering. The mortise and tenon steel-concrete structure has significant advantages such as high strength, good seismic performance, and convenient construction. It is widely used in construction pr...
