Abstract
Closed double-storied floor burrows mold, belongs to building installation engineering field, it is made of water drilling casing, hand rod, stationary jaw.Water drilling sleeve upper end is equipped with hand rod, and water drilling lower end is equipped with stationary jaw.Stationary jaw is 3 cone columns, and 3 cone columns etc. point are arranged in lower end circumferential edges；Hand rod has two bar angles at 45 ° to be fixed on sleeve outer wall.The utility model, using water drilling casing, makes water drilling drill bit stablize effective work when wearing double-storied floor and burrowing.The utility model structure is simple, easy to use, at low cost, high-efficient and safe.
Description
Technical field
The utility model belongs to building installation engineering field, before Pipe installing, needs to penetrate double-storied floor and burrows, and uses
Concentricity in precise positioning doubling plate hole.
Background technique
Many buildings extend double-storied floor to pursue exterior wall moulding or actual use function, part-structure floor at present,
Even multilayer floor slab.Double-storied floor is inevitably passed through when pipeline mounting construction again, this just needs to burrow in double-storied floor.
The method that floor burrows at present is usually to lengthen screw rod water drilling to burrow.With such technique, bilayer below for spacing 50CM
Floor, in drilling bit high-speed operating, bottom rhinestone head generates serious shift phenomenon, need to burrow again.For spacing 50CM with
On double-storied floor, drilling bit high-speed operating when, due to that can not be in close contact with lower layer's floor, drill bit offset when it is stuck can not be complete
At the work that burrows, or even machine can be damaged.Working efficiency is low, it is overall beautiful to influence.Therefore develop a kind of advanced mold that burrows
It burrows technique to improve existing double-storied floor, improves the quality at hole and improve labor efficiency.
Summary of the invention
To solve the above-mentioned problems, the present invention will provide the novel construction tool for being suitable for double-storied floor and burrowing --- closing
Formula double-storied floor burrows mold, after the completion of floor burrows on upper layer, the double-storied floor mold that burrow will be used to be fixed on upper layer floor
In hole, bottom is contacted with lower layer's floor close and firm, ensure that the concentricity at upper and lower level floor hole, low in cost, operation letter
List, one-pass molding, substantially increases labor efficiency at hole beauty.
The mold the technical scheme is that closed double-storied floor burrows, by water drilling casing, hand rod, stationary jaw
Composition.Water drilling sleeve upper end is equipped with hand rod, and water drilling lower end is equipped with stationary jaw.Stationary jaw is 3 cone columns,
3 cone columns etc. point are arranged in lower end circumferential edges；Hand rod has two bar angles at 45 ° to be fixed on sleeve outer wall.
Water drilling casing material is coating steel pipe, and length is that upper lower floor plate interval adds 30cm, and caliber is to amplify than reserved casing
No.1；Hand rod is two 18 screw-thread steels of Φ, and bar long 25cm is at 45 ° to be welded.Stationary jaw uses carbon constructional quality steel
It is cut into zigzag, wearability and good toughness.
User of the invention is first to get a hole (more bigger than lower layer floor) on the upper floor with water drilling, so
It is burrowed mold using the double-storied floor of same caliber afterwards, by the hole of mold insertion upper layer floor, the fixed jaw of mold bottom is tight
Tight penetrates lower layer's floor, while being fallen using the magnetic line of force mold being tuned into vertical state, finally will be equipped with the water drilling for lengthening screw rod
Drill bit is put into mold, is carried out water drilling and is burrowed.The utility model is of simple structure and low cost, easy to operate, hole is beautiful, one
Secondary molding substantially increases labor efficiency.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
Fig. 2 is the structure chart for being fixed on through-flooring hole when the utility model is used.
1, hand rod in figure, 2, water drilling casing, 3, stationary jaw, 4, upper layer floor, 5, lower layer's floor.
Specific embodiment
As shown in Figure 1 and Figure 2, closed double-storied floor burrows mold, by water drilling casing 2, hand rod 1,3 groups of stationary jaw
At.Water drilling sleeve upper end is equipped with hand rod, and water drilling lower end is equipped with stationary jaw.Stationary jaw be 3 cone columns, 3
A cone column etc. point is arranged in lower end circumferential edges；Hand rod has two bar angles at 45 ° to be fixed on sleeve outer wall.
The application method of the utility model: first getting a hole on the upper floor with water drilling, then by water drilling casing 2
Be inserted into the hole of upper layer floor, the bottom end fixing card 3 of water drilling casing 2 tightly penetrate lower layer's floor, while being fallen using the magnetic line of force
Water drilling casing 2 is tuned into vertical state, will be finally put into mold equipped with the water drilling drill bit for lengthening screw rod, directly initiate water drilling.
The utility model is of simple structure and low cost, easy to operate, hole is beautiful, one-pass molding, substantially increases labour
Efficiency.
