Abstract
The utility model discloses a reserved hole device of a concrete floor slab. The device comprises a metal sleeve, a metal cover plate and a hook bolt. The metal cover plate is arranged on the upper portion of the metal sleeve. A through hole is formed in the center of the metal cover plate. A hook end of the hook bolt is connected with a template of a top plate, and the other end of the hook bolt is fixed in the through hole through a nut. According to the reserved hole device of the concrete floor slab, a reserved position of a reserved hole can be precisely located, disassembly and cleaning are easy, cycling frequency of the device is increased, and meanwhile after the device is detached, attractiveness of the reserved hole can be well guaranteed.
Description
Technical field
The utility model relates to building field, especially relates to a kind of concrete floor hole to be provided device.
Background technology
At building field, upper and lower conduit road, heating pipe and the fire protection pipeline of cast-in-place concrete floor all needs to keep somewhere in advance hole to be provided.The form that adopts in work progress of concrete floor hole to be provided was varied in the past, often adopted simple device such as steel bushing, pvc pipe material sleeve.But in use, locate inaccurately, riding position easily is offset; The sleeve root is reinforced not firm, is offset in concreting process easily; Easily concrete is scattered as in the sleeve in the concreting process, causes cleaning and remove inconvenience, reduce the number of turnover; Build when removing after finishing and pound with a hammer, destroy the corner of hole to be provided easily, cause the impression of corner not attractive in appearance.
The utility model content
The purpose of this utility model provides a kind of concrete floor hole to be provided device, the accurately reserved location of hole to be provided, and dismounting cleaning easily, and the number of turnover of increase device after the device dismounting, can guarantee the attractive in appearance of hole to be provided simultaneously preferably.
For achieving the above object, the utility model provides a kind of concrete floor hole to be provided device, comprise metal sleeve, metal cover board and gib headed bolt, described metal cover board is arranged at described metal sleeve top, described metal cover board center is provided with open-work, the gib head end of described gib headed bolt is connected with roof plate template, and the other end is fixed in described through-hole position by nut.
Preferably, be connected for spot welding between described metal sleeve and the described metal cover board.
Preferably, be welded with bale handle on the described metal sleeve.
Preferably, be welded with backing pin on the described gib headed bolt.
Therefore, the utility model adopts the concrete floor hole to be provided device of said structure, the accurately reserved location of hole to be provided, and dismounting cleaning easily, and the number of turnover of increase device after the device dismounting, can guarantee the attractive in appearance of hole to be provided simultaneously preferably.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment
Embodiment
Fig. 1 is the structural representation of the utility model concrete floor hole to be provided device embodiment, Fig. 2 is the plan structure schematic diagram of the utility model concrete floor hole to be provided device embodiment, as shown in the figure, comprise metal sleeve 1, metal cover board 2 and gib headed bolt 3, metal cover board 2 is arranged at metal sleeve 1 top, is the spot welding syndeton between metal sleeve 1 and the metal cover board 2.Metal cover board 2 centers are provided with open-work 4, and the gib head end of gib headed bolt 3 is connected with roof plate template 5, and Fig. 3 is the mounting structure schematic diagram of the utility model concrete floor hole to be provided device embodiment, for clear statement, have also marked concrete floor 9 among Fig. 3.The other end of gib headed bolt 3 is fixed in open-work 4 places by nut 6.Metal sleeve 1 is the main body of hole to be provided pore-forming, and diameter needs big two specifications of pipe laying generally speaking, and its surface should be smooth as much as possible, in use should the brushing remover.Metal cover board 2 is welded in the top of steel sleeve, and predominant use is to prevent that in concreting process concrete is scattered in the metal sleeve 1, and open-work 4 is used to wear gib headed bolt 3, thus location and reinforce metal sleeve.After roof plate template 5 installs and finishes, survey and establish pipeline location, and punch, penetrate gib headed bolt 3, metal sleeve 1 is installed then at the center line of pipe laying, and fastening nut 6, location and reinforcing finish, and process is simple to operation.Be welded with backing pin 7 on the gib headed bolt 3, prevent that gib headed bolt 3 is shed to below the work plane in gib headed bolt 3 installations and metal sleeve 1 demolishing process.
Also be welded with bale handle 8 on the metal sleeve 1, be welded in metal sleeve 1 external surface, with rotating bale handle 8 and taking out metal sleeve 1, can not destroy the exterior appearance of hole to be provided after the concreting final set.
Therefore, the utility model adopts the concrete floor hole to be provided device of said structure, the accurately reserved location of hole to be provided, and dismounting cleaning easily, and the number of turnover of increase device after the device dismounting, can guarantee the attractive in appearance of hole to be provided simultaneously preferably.
It should be noted that at last: above embodiment is only in order to explanation the technical solution of the utility model but not limit it, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that: it still can make amendment or be equal to replacement the technical solution of the utility model, and these modifications or be equal to replacement and also can not make amended technical scheme break away from the spirit and scope of technical solutions of the utility model.
