Abstract
The utility model discloses a fixing device for a concrete conveying pipe. Two short pipes are butt jointed and are welded with a steel plate stop valve, and one end of the short pipe is connected with a steel pipe column through a hoop which is tightly fixed on the steel pipe column. The hoop is formed by enclosing two steel plates, one steel plate at one side is provided with a hole for allowing the short pipe to be inserted in, and the two steel plates are fastened by bolts. The fixing device has the beneficial effects that the concrete pouring amount can be effectively controlled by the stop valve; conveying pipe fixing does not need to be assisted manually, so that safety of constructors is ensured; the short pipe does not need to be pulled out immediately after the pouring of concrete is finished, and the concrete does not flow out, so that the integrity of the concrete is ensured; by utilizing the fixing device, the concrete can be poured by adopting a lift-up method, so that the construction period is shortened, and the assisting work load is reduced.
Description
Technical field
The utility model relates to a kind of fastening devices, specifically a kind of detachable concrete transportation pipe fixing device with stop valve.
Background technology
At present, in building operations, while building steel core concrete column, generally adopt the mode that carrier pipe is directly connected on steel pipe column to carry out concreting, this kind of method is difficult for fixed ducts in construction, also needs to fix with human assistance, has potential safety hazard, be unfavorable for concrete vibrating, affect concrete density.When having built, because carrier pipe is directly connected with steel pipe column, to extract after carrier pipe, the concrete of connecting portion very easily flows out, and affects the globality of steel core concrete column, causes quality problems.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of detachable concrete transportation pipe fixing device with stop valve, improve traditional steel core concrete column and build connected mode, a kind of safe, economic, efficient connected mode is provided, can change original steel core concrete column casting method---high throwing method is built, and adopts lift-up method more easily to build concrete filled steel tube.
The technical solution of the utility model is achieved in that a kind of concrete transportation pipe fixing device, it is characterized in that, two short tubes (3) docking and steel plate stop valve (4) welding, short tube (3) one end is by cuff (1) joint steel pipe post, and cuff (1) is fastened on steel pipe column.Described cuff (1) is that two block plates surround, and steel plate one STH can insert short tube (3), fastening by bolt (2) between two block plates.The timber wedge of jumping a queue between described cuff (1) and steel pipe column is fastening.The steel plate that described steel plate stop valve (4) is middle perforate, the aperture of perforate is identical with the external diameter of short tube (3).Described steel pipe column perforate, the aperture of perforate is equal to, or greater than the external diameter of short tube (3), and short tube (3) docks or inserts with steel pipe column.Described short tube (3) is provided with rubber washer with steel pipe column junction.
The beneficial effects of the utility model are: 1, stop valve can effectively be controlled concreting amount; 2, need not human assistance fixed ducts, ensured constructor's safety; 3, after concreting completes, need not extract immediately short tube, concrete can not flow out, and has guaranteed concrete globality; 4, utilize the utility model, can adopt lift-up method concreting, shortened the duration, reduced back work workload.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further explained to explanation.
As Figure 1-4, concrete transportation pipe fixing device, comprise steel plate stop valve 4, short tube 3, bolt 2, cuff 1, 4 perforates of steel plate stop valve are identical with short tube 3 external diameters, two short tube docking are welded with steel plate stop valve 4, insert in steel pipe column by cuff 1 short tube 3 one end, cuff 1 is that two block plates press-bendings are made, its light plate one STH, aperture is slightly larger than short tube 3 external diameters can insert short tube (3), cuff 1 is fastened on steel pipe column by bolt 2, not loosening for guaranteeing cuff 1, the timber wedge of can jumping a queue between cuff 1 and steel pipe column, steel pipe column is also wanted perforate, aperture equals or is slightly larger than the external diameter of short tube 3, short tube 3 docks or inserts with steel pipe column hole place, junction adds rubber washer.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; according to the technical solution of the utility model and utility model design thereof, be equal to replacement or changed, within all should being encompassed in protection domain of the present utility model.
