Embodiment Construction
[0023] The technical solutions in the embodiments of the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention.
[0024] The invention is attached Figure 1-15 shown. A concrete composite beam includes a prefabricated beam 1, a prefabricated component plate 11, erecting steel bars 14, and a concrete laminated layer 13. The upper side of the middle part of the prefabricated beam 1 is provided with a through transverse groove 5, and the prefabricated beam 1 is pre-embedded with a longitudinal Reinforcing bars 4, stirrups 3, and transverse grooves 5 of the prefabricated beams are provided with reinforcements 6. Such as figure 1 , 2 As shown, reinforcement 6 is pre-embedded in transverse groove 5 of prefabricated beam 1. When the beam is placed in the middle, the pre-embedded reinforcement 6 is cut off, and the construction is convenient and quick. Such as image 3 As shown, the hole 16 reserved on the ...

The invention discloses a concrete composite beam. The concrete composite beam comprises a precast beam (1), a precast element plate (8), an erection bar (14), and a concrete composite layer (13), wherein the upper side of the middle of the precast beam (1) is provided with a perforated transverse groove (5), and the transverse groove (5) of the precast beam (1) is provided with a reinforcement piece (6). When the beam is installed, the beam required to be erected is shelved in the transverse groove (5) to form a criss-cross primary and secondary beam system, the precast element plate (8) is shelved on the beam, the precast element plate (8) and a beam upper part whole cast-in-place concrete superposition layer (13) form a concrete composite beam plate system; and the reinforcement piece (6) of the transverse groove (5) of the precast beam guarantees that the beam is not easy to snap, crack or disrepair in a lifting construction process, the beam can be precast with a hollow part (20); the form of an end part and the grooves (19) at two sides of the transverse groove (5) ensure the effective high-strength connection between a beam column and the beam and a beam node. The composite beam is suitable for general industry and civilian construction.
Description
technical field [0001] The invention relates to the field of construction, in particular to a concrete composite beam. Background technique [0002] Nowadays, due to the fact that the assembled integral structure combines the monolithic concrete structure and the assembled whole, it is widely used abroad, and it is also in the promotion stage in my country, and the research on the assembled integral structure in China is gradually increasing. Therefore, the assembled integral structure The structure has a good application prospect. However, the assembled monolithic structure still has the problem of poor integrity. The composite beam is a whole structure formed by prefabricating part in the prefabricated site and partly cast-in-place at the construction site. At present, prefabricated beams are mostly made into T-shaped or rectangular cross-sections. When hoisting or transporting prefabricated beams in prefabricated places, quality problems such as breakage and cracks are p...
