Abstract
The utility model relates to an overflow pressure relieving device for concrete lift-up construction of a steel pipe column. The overflow pressure relieving device comprises a steel pipe column and a straight pipe installed on the steel pipe column; wherein the straight pipe is bent downward in the same plane at an angle of Alpha equal to or larger than 60 degree and equal to or smaller than 90 degree from the position where the straight pipe is connected with the steel pipe column, and a hose is fixedly installed at the pipe opening end. The overflow pressure relieving device has the advantages that the construction cost is effectively reduced, concrete pouring is easy to control, construction safety and reliability are improved, and both the time and the labor are saved, thereby being an overflow pressure relieving device easy to manufacture.
Description
Technical field
The utility model belongs to building field, especially a kind of overflow pressure relief device that is used for the construction of steel pipe column concrete lift-up.
Background technology
In industrial construction, particularly in the large scale industry workshop building, the increasing steel pipe column concrete column structure that adopts replaces traditional steel column structure, the steel pipe column concrete structure is compared with the steel column structure, under the close condition identical that keep self-respect with bearing capacity, significantly save steel, met the policy of national energy-saving and emission-reduction; The steel pipe column concrete structure is compared with ordinary reinforced concrete structure, is keeping under the condition that rolled steel dosage is close or bearing capacity is identical, and space hold is few, own wt is light, effectively reduces construction land tenure, and can guarantee workmanship, can shorten the construction period simultaneously.Whether in the steel pipe column concrete lift-up construction at present, the steel pipe column top is provided with steam vent, be used for release and observe concrete and pour into and put in place, this mode is difficult to control concrete perfusion degree, if pour into not in placely, needs secondary pouring, promptly waste raw material and artificial, concrete is leakiness again, puts in place if concrete once pours into, and concrete will overflow by steam vent, pollute steel pipe column, the labor cleaning is wasted time and energy, and increases construction cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of overflow pressure relief device that is used for the construction of steel pipe column concrete lift-up is provided, and this device effectively reduces construction cost, and concrete spouting is controlled easily, improved working security and reliability, time saving and energy saving.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of overflow pressure relief device that is used for the construction of steel pipe column concrete lift-up, comprise a steel pipe column and a straight tube of installing above with steel pipe column, isoplanar is bent downwardly two α degree from beginning respectively with the connecting portion of steel pipe column with straight tube for it, and 60≤α≤90 install a flexible pipe at nose end.
And described flexible pipe uses wire rope and stirrup colligation in right-hand member mouth of pipe lower end.
And described straight tube is connected with the flange that is connected to of steel pipe column.
And described flexible pipe is a plastic flexible pipe.
Advantage of the present invention and beneficial effect are:
1, originally be used for steel pipe column concrete lift-up construction the overflow pressure relief device its begin respectively from connecting portion straight tube that the isoplanar is bent downwardly two α degree with steel pipe column, 60≤α≤90, install a flexible pipe at nose end, this device when the jacking concrete when pumping twice concrete in the flexible pipe, be that jack-up construction finishes, observe the concrete perfusion of control easily, and the concrete that pumps can directly not stayed on the steel pipe column, reduced the time of cleaning steel pipe column, concrete is once poured into put in place, ensure the compactness of concrete integral body.
2, the straight tube that originally is used for the overflow pressure relief device of steel pipe column concrete lift-up construction is connected with the flange that is connected to of steel pipe column, flexible pipe adopts plastic flexible pipe, raw material wide material sources, flange connect the loading and unloading of this device can convenient construction the time, and this device can reuse.
3, the utility model effectively reduces construction cost, and concrete spouting is controlled easily, has improved working security and reliability, and is time saving and energy saving, is a kind of overflow pressure relief device that simply is used for the construction of steel pipe column concrete lift-up of making.
Description of drawings
The structural representation that Fig. 1 uses on steel pipe column for the utility model.
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of overflow pressure relief device that is used for the construction of steel pipe column concrete lift-up, comprise a steel pipe column 1 and a straight tube 5 of installing above with steel pipe column, straight tube connects with adopting flange 4 being connected of steel pipe column, rubber washer 2 is installed between the flange, the isoplanar is bent downwardly two α degree to this straight tube from beginning respectively with 3 positions, gas outlet of steel pipe column, 60≤α≤90, present embodiment two α shown in the drawings respectively are 90 degree, install a flexible pipe 8 at nose end, flexible pipe uses wire rope 6 and stirrup 7 colligations in right-hand member mouth of pipe lower end, and flexible pipe is a plastic flexible pipe.
Straight tube was connected with the gas outlet of steel pipe column by flange when the utility model was used, the other end is arranged on the outside of steel pipe column, when carrying out the jacking concrete, observes the plastic flexible pipe on the utility model, when pumping twice concrete in the plastic flexible pipe, i.e. jacking concrete construction finishes.In the concrete process of jacking, this device plays the effect of release.
Claims (4)
