Description

Technical Field:

[0001] The utility model relates to the technical field of ribbed floor construction, and particularly relates to a rib beam steel bar positioning device for cast-in-place ribbed floor construction. Background Art:

[0002] A ribbed floor is composed of a thin plate and rib beams with a small spacing. It is divided into two types: one-way ribbed floor and two-way ribbed floor. During the construction of a ribbed floor, usually a number of prefabricated rib molds are laid flat at the construction site, and then a large number of rib beam steel bars are installed between every two rib molds to ensure that the rib molds will not shift or skew, and at the same time to ensure that the strength of the concrete rib beams formed during subsequent concrete pouring will not be too low.

[0003] The utility model patent with the publication number of CN 220747434 U discloses a rib beam steel bar positioning device for cast-in-place ribbed floor construction, which includes an upper mold and a lower mold for installation at the intersection of two external rib beam steel bars. The upper mold and the lower mold are stacked, and a receiving groove for accommodating the intersection of two external rib beam steel bars is formed between them. A connecting member for fixedly connecting the upper mold and the lower mold is arranged between the upper mold and the lower mold. Through the connection and combination of the connecting members, a limiting shell is formed, and four through holes for two external rib beam steel bars to pass through are opened on the limiting shell. This utility model solves the problems in the prior art that the intersection of adjacent rib beam steel bars is prone to breakage or separation when concrete fluid is poured or impacted by external stress, and the connection strength at the intersection of rib beam steel bars is too low.

[0004] However, the above device still has some disadvantages in actual use. The more obvious one is that in actual production, due to different construction requirements and the sizes of ribbed floors, the sizes of the rib beam steel bars used are also different. When positioning the rib beam steel bars, since the sizes of the through holes and perforations are fixed, this device can only position rib beam steel bars with fixed sizes and cannot adapt to the positioning of rib beam steel bars with different sizes, so the practicability is low. And when installing the rib beam steel bars with this device, it is necessary to manually pass the rib beam steel bars through the through holes and perforations, which is difficult to operate, time-consuming and laborious, and very inconvenient to use.

[0005] Therefore, the utility model proposes a rib beam steel bar positioning device for cast-in-place ribbed floor construction to solve the above problems. Summary of the Invention:
