Description
Technical field
The utility model relates to a kind of detachable steel sleeve for through-flooring reserved opening.
Background technology
Build in short supply and the deficient and modern urban construction development need of land resources, common precast floor slab fades out, and full monolithic reinforced concrete structure builds extensive use.Full monolithic reinforced concrete structure, using function is more and more complete, various electric wire, ventilating duct, upper and lower conduit road a large amount of passing through floors, particularly washroom and kitchen are that through-flooring pipeline is comparatively concentrated, place that quantity is maximum, normally pipe laying after reserved opening in advance.
Usual reserved opening method is: remove after the reserved opening methods such as pre-buried fragment of brick, wooden unit, steel pipe and construct, above way was both taken a lot of work, take material, be also difficult to dismounting, follow-up shutoff difficulty is large, once process bad reserved opening position will leave the hidden trouble seeping water and leak, maintenance cost is huge.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of detachable steel sleeve for through-flooring reserved opening.
For the technical problem that will solve, the technical solution adopted in the utility model is: a kind of detachable steel sleeve for through-flooring reserved opening, comprises upper and lower; Top is inverted tapered steel rounding platform, and the end face of round platform and bottom surface steel plate are closed; The steel sheet pile of round platform end face welding for rotating, the both sides welded reinforcement handle of round platform end face;
Bottom is steel pipe, and steel pipe welds with round platform bottom surface, and steel pipe periphery is provided with crin and buckles, and the outside of steel pipe is threaded connection with the steel pipe socket being provided with interior screw thread, closes bottom steel pipe socket with steel plate.
As preferably, the thickness height 50mm of the aspect ratio floor of round platform, the end face diameter of round platform compared the large 100mm of external diameter of floor slab pipeline, and round platform basal diameter compared the large 40mm of floor slab pipeline external diameter.
As preferably, the diameter of steel pipe was greater than floor slab pipeline diameter 15mm, and steel pipe height is 80mm.
As preferably, also comprise rubber washer; Described rubber washer is bonded in round platform bottom surface, and thickness is 5mm.
The beneficial effects of the utility model are:
Adopt dismountable steel die to form reserved opening, assembling and disassembling is convenient, and reserved opening accuracy is high; sealing hole is easy, and can save a large amount of artificial and material, reduces urban construction rubbish and produces; protection of the environment, increases floor water resistance, utterly destroys seepage.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the detachable steel sleeve embodiment of the utility model.
Fig. 2 is the perspective view of the detachable steel sleeve embodiment of the utility model.
Fig. 3 is the scheme of installation of the detachable steel sleeve embodiment of the utility model.
In figure, 1-handle, 2-steel sheet pile, 3-round platform, 4-steel pipe, 5-steel pipe socket, 6-rubber washer, 7-base plate template.
Detailed description of the invention
One, prefabricated band casement plate
According to reserved holes of pipes mouth distribution situation and the plane size in washroom, kitchen, the base plate template of this part floor is divided into some pieces (ensureing that openings position template becomes monoblock to be advisable) as far as possible, accurately find out the home position at each hole and carry out mark, with round hole device by for subsequent use for template perforate, what bore size ratio was formally installed crosses the large 20mm of floor slab pipeline external diameter.
Two, making releasable circular steel jacketing is mould
As shown in Figure 1, circular steel jacketing is divided into two, upper and lower part:
1, top is inverted horn-like round platform 3, and the aspect ratio slab thickness height 50mm of round platform, back cut diameter compared the large 100mm of floor slab pipeline external diameter, and lower port diameter compared the large 40mm of floor slab pipeline external diameter.The end face of round platform and bottom surface Plate Welding tight-closed, the steel plate of round platform end face is welded with reinforcing bar handle 1 and the steel sheet pile 2 with holes for rotating steel sleeve.
2, bottom is steel pipe 4, and diameter of steel tube compared the large 15mm of floor slab pipeline diameter, and length is 80mm crin button in addition, is the steel pipe socket 5 (Fig. 2) being with the size with it of the bottom lock of interior screw thread supporting outside crin button.
3, at round platform bottom surface, the top rubber washer 6 that bonding 5mm is thick in advance, diameter is identical with round platform bottom surface external diameter.
Specific construction flow process:
(1) base plate template with holes is made;
(2) base plate model sheetinstallat, colligation floor bar;
(3) in hole to be provided position, releasable circular steel jacketing is installed, first rubber washer 6 is inserted in the steel pipe 4 of circular steel jacketing bottom, again steel pipe 4 is inserted in the preformed hole of base plate template, the steel pipe socket 5 of outside screwed on also makes the rubber washer 6 of releasable circular steel jacketing be close to base plate template 7 (Fig. 3), spillage during to prevent fluid concrete;
(4) floorslab concrete is built;
(5) after concrete initial set, insert in the perforate of the upper steel sheet pile 2 of circular steel jacketing bar reinforcement slowly rotate circular steel jacketing by its loosen; Rotate when concrete strength reaches 2.5Mpa and remove steel sleeve and clear up for subsequent use;
(6) check openings position and size and find that deviation processes immediately.
The present embodiment adopts prefab form (with holes) and prefabricated releasable circular steel jacketing reserved opening technique, eliminate the position that between boiled water room, reserved opening uses common process and way to bring in work progress such as existing kitchen, washroom to be forbidden, remove difficulty, not easily shutoff causes leakage problems.
Above-described the utility model embodiment, does not form the restriction to the utility model protection domain.Any do within spirit of the present utility model and principle amendment, equivalent to replace and improvement etc., all should be included within claims of the present utility model.
