Abstract
A floor preformed hole construction sleeve includes a steel sleeve. The floor preformed hole construction sleeve is characterized in that the diameter of the steel sleeve is consistent to the size of the floor preformed hole, the height of the steel sleeve is consistent to the thickness of the floor, the upper portion of the steel sleeve is covered by a sealed cover plate; the upper edge of the steel sleeve is connected with the handle of the sleeve; the bottom of the steel sleeve is provided with a bottom steel plate; two sides of the center of the bottom steel plate are symmetrically provided with self tapping screw holes; the center of the bottom steel plate is connected with a screw rod which is concentric with the steel sleeve; and the upper end of the screw rod passes through the sealed cover plate to be connected with a fastening nut. The bottom steel plate is chisel-shaped, cross-shaped, star-shaped or circular, and the length of the bottom steel plate is not more than the diameter of the steel sleeve. In the utility model, the mounting and dismounting is convenient, the fixation is firm, the contact to a template is compact, slurry leakage is prevented, the position of the preformed hole is accurate, the profile is beautiful, repeat usage is available, waste of artificial work and materials is avoided, and the floor preformed hole construction sleeve can be widely applied in building structure construction.
Description
Technical field
The utility model relates to a kind of structure construction instrument, particularly a kind of floor reserving hole construction sleeve.
Background technology
When structure construction, the sleeve pipe installation is a very strict operation during floor reserving hole, and common practices is with iron nail and iron wire colligation fixed sleeving; This mode very easily goes wrong in construction, mainly shows fixing insecure, contacts imprecision with template; Easy spillage when concrete pouring must also can destroy floor through picking cutter ability pore-forming after causing sleeve pipe to take out sometimes; Cause the waste of manual work, material, construction is also inconvenient.
The utility model content
The purpose of the utility model provides a kind of floor reserving hole construction sleeve, solve fixing insecure, the contact imprecision of the sleeve that exists when traditional floor reserving hole sleeve pipe is installed, the technical problem of spillage easily; And solve sleeve pipe and can't reuse, cause that cost rises, the problem of construction inconvenience.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of floor reserving hole construction sleeve; Comprise steel bushing, it is characterized in that: the diameter of said steel bushing and floor reserving hole adapt, and height adapts with slab thickness; Closed cover is stamped on the top of steel bushing; The upper edge of steel bushing is connected with the sleeve pipe handle, and the bottom steel plate is arranged at the bottom of steel bushing, and bilateral symmetry has the self-tapping screw hole to said bottom steel plate at the center; The center of bottom steel plate is connected with a screw rod concentric with steel bushing, and the upper end of said screw rod is passed closed cover and is connected with clamp nut.
Said bottom steel plate can be in-line, cross, M shape or circle, and its length is not more than the steel bushing diameter.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The utility model has overcome the sleeve pipe that exists when traditional floor reserving hole sleeve pipe is installed can't be reused, and causes that cost rises, the shortcoming of construction inconvenience, has solved fixing insecure, the contact imprecision of sleeve, spillage technical problem easily.
The utlity model has following technological progress:
The utility model has solved all disadvantages that produce in the previous ordinary casing construction, and its advantage is that installation and removal are convenient, fixation; Contact tightly with template, stopped the spillage phenomenon, make the reserving hole position accurate; Good looking appearance; And reusable, as to have stopped artificial and material waste can be widely used in the building structure construction.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the utility model bottom surface structural representation.
Reference numeral: 1-sleeve pipe handle, 2-steel bushing, 3-screw rod, 4-self-tapping screw hole, 5-bottom steel plate, 6-clamp nut, 7-closed cover.
The specific embodiment
Embodiment is referring to Fig. 1, shown in Figure 2, and a kind of floor reserving hole construction sleeve comprises steel bushing 2; It is characterized in that: the diameter of said steel bushing 2 and floor reserving hole adapt; Height adapts with slab thickness, and closed cover 7 is stamped on the top of steel bushing 2, and the upper edge of steel bushing 2 is connected with sleeve pipe handle 1; Bottom steel plate 5 is arranged at the bottom of steel bushing 2; Bilateral symmetry has the self-tapping screw hole 4 that is used to connect template at the center for said bottom steel plate 5, and the center of bottom steel plate 5 is connected with a screw rod 3 concentric with steel bushing, and the upper end of said screw rod 3 is passed closed cover 7 and is connected with clamp nut 6.
Said bottom steel plate 5 is cross, M shape or circle, and its length is not more than steel bushing 2 diameters.
Method for using: during construction; Use self-tapping screw bottom steel plate 5 to be fixed on the kapok plate of construction floor, after the upper end of screw rod 3 is passed closed cover 7 and is connected firmly with clamp nut 6, begin to carry out concreting; When concrete setting reaches 70% left and right sides, steel bushing 2 is extracted.
