Abstract
A floor slab preformed hole device relates to the field of building installation, in particular to a floor slab preformed hole device. The floor slab preformed hole device consists of a sleeve (1), a cover plate (2) and a self-tapping screw (3), wherein the sleeve (1) is arranged at a position of the preformed hole above a plywood formwork (4), the front cover plate (2) is arranged on the sleeve (1), the self-tapping screw (3) penetrates through the middle of the cover plate (2), and the front end of the self-tapping screw (3) is screwed into the plywood formwork (4). By utilizing the floor slab preformed hole device, the preformed hole can be completed with fast and simple process, can be positioned by the self-tapping screw (3) with firm fixation and can not be shifted during casting process, thereby guaranteeing accurate position of the hole.
Description
Technical field:
The utility model relates to a kind of construction and installation field, is specifically related to a kind of floor hole to be provided device.
Background technology:
In the project subject structure construction procedure,, on floor, there is a large amount of reservations hole to stay in the design and establishes because installing engineering needs.These holes generally all adopted the nail tub to reserve with the fixing mode of iron wire colligation in the past, but this exist spillage of material big, complexity is installed and exists the floor concrete to build in the process problems such as easy off normal.
