Description
Technical Field
The utility model relates to a construction technical field specifically is a basement floor post-cast strip dowel steel buries piece.
Background
In modern city construction, based on the rising of space utilization, the foundation burial depth is continuously increased, and more deep foundation pit projects appear. In order to avoid influencing the facilities such as the existing buildings, city pipe networks and the like around, an inner supporting beam plate structure is often adopted to temporarily support and support the pressure of water and soil and an additional load so as to keep the stability of a foundation pit and provide a safe operation environment for construction. When the underground main structure is constructed to a certain stage, the corresponding inner support has to be dismantled. Before the inner support is dismantled, the main structure needs to support the foundation pit supporting structure, and the horizontal load transmitted by the supporting structure after the inner support is dismantled is born by the rigidity of the main structure beam, the plate, the wall and other members, so that a new stress balance is established between the underground structure and the foundation pit supporting structure. Namely, the supporting structure realizes the transfer and redistribution of internal stress before and after the inner support is dismantled. The post-cast strip part is provided with an opening so that horizontal force cannot be continuously transmitted, and therefore force transmission components are arranged between the post-cast strips to form integral rigidity, and therefore the post-cast strip force transmission rod embedded part for the basement floor is needed.
At present, the basement floor slab post-cast strip dowel bar embedded part usually adopts I-steel, channel steel or angle steel to transmit the horizontal force of the missing part, but the method has certain limitation and drawback, the post-cast strip both sides are connected into a whole, the uneven settlement of the structure on the post-cast strip both sides is restrained, the stress formed inside the structure is uneven, the local stress is large, and the crack formed by the main structure is easily caused.
