Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a fastening member. Background Art

[0002] The laminated slab plays a load-bearing role in the precast structure. After bearing the surface load, it can realize the transfer to the shear wall or other force-bearing structures, forming a reliable transfer path and giving full play to the bearing capacity of each structure. However, under the restrictive effect of the precast construction technology level, the connection formed between the laminated slabs lacks tightness, and slurry leakage occurs during the concrete pouring construction, resulting in poor appearance quality of the formed concrete and even affecting the performance of the structure such as strength. In response to this, at present, it is processed by applying multiple layers of putty later, but this process is time-consuming and laborious.

[0003] At present, most precast projects still adopt the construction of PC laminated slabs with wooden formwork. There is a large difference in stiffness between the PC laminated slab and the formwork at the bottom of the slab. During the concrete pouring process, due to the large stiffness of the PC laminated slab, the deformation during pouring is small; while the stiffness of the formwork is small, and the deformation during concrete pouring is large. The different degrees of deformation between the two cause gaps between the slab strip formwork and the PC laminated slab, resulting in slurry leakage at the bottom of the slab strip. If the control of slurry leakage at the junction of the PC laminated slab and the cast-in-place beam is not ideal, it will cause an increase in processes such as cutting, chiseling, secondary plastering, and detailed grinding, thus leading to an increase in costs.

[0004] In view of the problems of lack of tightness in the connection formed between the laminated slabs and slurry leakage caused by the gaps between the slab strip formwork and the PC laminated slab in the prior art, those skilled in the art have been looking for solutions.
