Description

TECHNICAL FIELD

[0001] The utility model relates to building technical field, in particular to a pre -buried structure. BACKGROUND

[0002] In the field of construction, steel and concrete composite structure is widely used in various construction projects due to its high strength and high durability. Among them, the steel reinforced concrete beam has better ductility and seismic performance than the traditional concrete beam, and is more and more used by buildings.

[0003] In the building structure, the stability of the wall directly relates to the safety performance of the building. When the length or height of the inner and outer wall is long or high, the stability outside the plane is significantly reduced, and the phenomenon of out-of-plane instability is easy to occur. Therefore, in engineering practice, the construction measure of setting up steel structure supporting column in the wall at a certain interval is usually taken, so as to shorten the effective calculation length of the wall and improve the lateral stiffness and overall stability of the wall. Among them, the steel structure supporting column is fixedly connected with the structure beam at the top and bottom of the wall.

[0004] In the prior art, the anchor pre-embedded part is a conventional connecting mode of the concrete beam and the steel structure supporting column, the anchor pre-embedded part is pre-embedded into the steel reinforcement cage of the concrete beam and is co-cast with the concrete beam, and the steel structure supporting column is fixed on the end plate of the pre-embedded part. When the anchor pre-embedded part is applied to the steel reinforced concrete beam, the pre-embedded anchor and the steel girder and the main reinforcement are crossed in space, and the steel girder needs to be processed by opening a hole in the construction, which reduces the bearing capacity of the steel reinforced concrete beam. At the same time, the dense anchor and the steel girder and the main reinforcement overlap to form a complex space grid, which is not conducive to the flow and vibration compaction of concrete, and quality defects such as honeycomb and hole are easy to occur, which further reduces the bearing capacity of the steel reinforced concrete beam. The steel girder opening or the anchor and the steel girder and the main reinforcement overlapping in the above make the steel reinforced concrete beam crack or even be damaged when bearing the design load or normal use load, which reduces the structural safety of the steel reinforced concrete beam.

The embedded component 1 includes a horizontally arranged upper support plate 11 and a connecting plate 12 that is cross-fixed with the upper support plate 11. At least one reinforcing plate 13 is fixedly provided on the connecting plate 12 on one side of the upper support plate 11. At least one groove 3 for inserting the flange plate of the steel beam 2 is provided on the reinforcing plate 13. The groove 3 is located at the lower part of the upper support plate 11.

[0037] An embedded structure according to an embodiment of this utility model includes an upper support plate 11 and a connecting plate 12 that are perpendicularly and fixedly connected to each other. A reinforcing plate 13 is provided on the inner side of the connecting plate 12, and a groove 3 is provided on the reinforcing plate 13. During installation, the flange plate 21 of the steel beam 2 is inserted into the groove 3 of the embedded structure for fixation. The steel structure buttress column is fixedly installed on the upper support plate 11. This design not only simplifies the installation process of the embedded structure and reduces the need for on-site welding and drilling, avoiding the weakening of the load-bearing capacity of the steel-concrete beam due to drilling, but also avoids the overlap of anchor bars with the steel beam 2 and main reinforcement, ensuring the quality of concrete pouring. Simultaneously, after the flange plate 21 of the steel beam 2 is inserted into the groove 3 of the embedded structure, the pouring space formed by the two is simple and regular.
