The utility model discloses simple structure, the commonality is strong, can effectively improve the disposable pre-buried fashioned qualification rate of riser sleeve pipe, and behind the piping erection, the riser sleeve pipe concentricity is high, can effectively solve the poor and not tight problem of shutoff of riser sleeve pipe installation concentricity that the pre-buried upper and lower layer dislocation of riser sleeve pipe leads to.
Description
Technical Field
The utility model belongs to building trade embedded sleeve pipe appurtenance field for improve the embedded precision of riser sleeve pipe and disposable embedded shaping qualification rate.
Background
In the building installation engineering, a large amount of indoor pipeline installation work exists, and a vertical pipe sleeve must be installed when various pipelines pass through a floor slab. At present, the common method for embedding the riser sleeve is to embed foam or temporary sleeve firstly and then adjust the sleeve during later installation, so that the embedding progress is low, and the hole filling outside the sleeve also has serious hidden trouble of water leakage, thereby influencing the construction quality.
The Chinese patent with the publication number of CN103243911A discloses a construction method for integrally shaping and one-time positioning a steel casing in a building shaft, which uses a plurality of components such as a casing center positioning plate, a casing group integral positioning die, a fixing lug and a plumb bob instrument to be matched for integrally shaping the steel casing in the building shaft, and only uses the casing center positioning plate for auxiliary positioning when positioning at the first floor, and the casing group integral positioning die is matched with the positioning casing and welded and fixed, so that the operation process is very complicated, and the construction method is only suitable for installation of the steel casing in the building shaft, and has poor adaptability when the position of an upper vertical pipe is changed.
Disclosure of Invention
The utility model aims at solving the problem that prior art exists, provide one kind when riser sleeve pipe pre-buried construction, easy and simple to handle, the commonality is strong, the riser sleeve pipe can once only pre-buried fashioned appurtenance.
The utility model adopts the following technical scheme:
an auxiliary tool for installing and positioning a riser sleeve comprises a positioning disc with a central hole, a nut and a screw, wherein the positioning disc can be placed in the sleeve, the nut is welded on the upper surface of the positioning disc, and the screw can be assembled in the nut.
The centre bore diameter of location disc is 3 ~ 5 mm. The diameter of the positioning disc is 1-2 mm smaller than the inner diameter of the vertical pipe sleeve.
The utility model discloses simple structure, the commonality is strong, can effectively improve the disposable pre-buried fashioned qualification rate of riser sleeve pipe, and behind the piping erection, the riser sleeve pipe concentricity is high, can effectively solve the poor and not tight problem of shutoff of riser sleeve pipe installation concentricity that the pre-buried upper and lower layer dislocation of riser sleeve pipe leads to.

FIG. 2 is a schematic structural view of a riser casing;
fig. 3 is a schematic view of the present invention.
Detailed Description
The contents of the present invention will be further explained with reference to the drawings attached to the specification.
As shown in figure 1, the auxiliary tool for the installation and positioning of the riser sleeve comprises a positioning disc 1 with a central hole 2, a nut 3 welded on the upper surface of the positioning disc and a detachable screw rod 4 capable of being assembled in the nut, wherein the positioning disc can be placed in a sleeve 7. The sleeve 7 is shown in fig. 2, and has a positioning wing ring 5 at the bottom, and a mounting hole 6 is formed on the positioning wing ring, and nails 13 can be inserted through the mounting hole to fix the positioning wing ring on the floor or the formwork 11. The positioning wing ring also has a certain waterproof function. The positioning wing ring and the sleeve are welded to form a wing ring sleeve. The positioning disc 1 is a circular steel plate, and the diameter of a center hole 2 of the positioning disc is 3-5 mm. The diameter of the positioning disc is 1-2 mm smaller than the inner diameter of the sleeve, so that the positioning disc 2 can be taken out of the sleeve 7 conveniently. The screw 4 can be screwed into the nut 3 on the positioning disc to facilitate removal of the positioning disc from the sleeve.
Adopt the utility model discloses the method of carrying out sleeve pipe installation location is shown in figure 3:
a. the sleeve 7 with the positioning wing ring 5 is placed on a floor slab or a template 11 of a first floor of a building, nails 13 penetrate through the mounting holes 6, the sleeve is fixed on the floor slab or the template, and then the positioning disc 1 is placed in the sleeve, so that the central hole 2 of the disc is aligned with the central position of the sleeve of the first floor. After the positioning disc is adjusted to be horizontal, the infrared plummet apparatus 8 is placed in the center of the sleeve, the plummet apparatus is adjusted to be horizontal and set out, the vertical center is aligned to the center of the positioning disc, and the position of the plummet apparatus light beam 9 projected on the upper template is the center position of the upper layer sleeve;
b. after the central position of the upper-layer sleeve is determined by the infrared plumb bob instrument 8, nails 10 are nailed in and penetrate out of the upper-layer template 12, and the central position of the upper-layer sleeve is determined in sequence;
c. take out the plumb appearance from the sleeve pipe, follow the sleeve pipe and go up the mouth with screw rod 4 screw in nut 3, take out positioning disc 1 and move to upper template 12 faces, positioning disc central hole is aimed at the nail point and is placed, rechecks sleeve pipe plane position, places the sleeve pipe along positioning disc 1 and fixes, and successive layer location installation upper casing pipe in proper order.
Use the utility model discloses, sleeve pipe 7 also can be the sleeve pipe of not taking the location wing ring, and the sleeve pipe bottom can weld ear knot or reinforcing bar, fixes in the template through the nail.
Adopt the utility model discloses, can confirm sleeve pipe central point fast and fix a position recheck layer upon layer. The utility model discloses application scope is wide, is applicable to the sleeve pipe location installation of all riser systems, and when upper riser specification and dimension changed or the position changed, this layer of sleeve pipe position of relocation can, convenient operation.
