Abstract
The utility model relates to a steel pipe concrete pillar, in particular to hydraulic hoisting equipment of the steel pipe concrete pillar. An air exhausting device for hoisting a steel pipe pillar concrete comprises a steel pipe pillar and an air exhausting steel pipe, wherein the side wall of the top part of the steel pipe pillar is provided with an air exhausting hole way, one end of the air exhausting steel pipe is provided with a screw thread, one end of the steel pipe, without the screw thread, is welded on the side wall of the top part of the steel pipe pillar, and the other end of the exhausting steel pipe is connected with a rubber pipe which is vertical to the ground through the screw thread. The air exhausting device can discharge redundantly-overflowed concrete grout liquid to the ground in an organized way under the natural condition. Therefore, the air exhausting device not only can not pollute the appearance quality of a steel component, but also is good for the normal operation of the grouting and the air exhausting, ensures the grouting effect, and improves the efficiency and the quality for hoisting the concrete.
Description
Technical field
The utility model relates to steel pipe column, relates in particular to steel pipe pillar hydraulic jacking equipment.
Background technology
Steel-concrete combined column inner concrete pumping, jacking is to utilize concrete pump that closely knit concrete is poured into until filling with whole pipe from steel pipe column bottom jacking, near offering grout hole in the column bottom, establish steam vent near post shoulder beam position, grouting is from the lower end, rise gradually, gas and concrete slurry are organized to flow out from steam vent.In the slip casting exhaust process in the past, slurries are when the capital steam vent flows out in the steel pipe column, the concrete slurry that flows out can pollute other steel members such as pillar, crane girder, so must send the staff that the steel member that pollutes is cleared up timely, and the cleaning difficulty is very big, needs work high above the ground, as the steel member of in time not clearing up, not only influence the presentation quality of steel member, and intractable is clean in the future.It is very big to the steel member outward appearance infringement at scene to accumulate over a long period like this, not only influences the presentation quality of member, consumes human and material resources again the steel member that pollutes is in time cleared up.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and a kind of exhaust plant of steel pipe column is provided.The utility model can be under the situation of nature with the unnecessary concrete slurry that overflows by the organized ground that is discharged to of exhaust plant.So not only can not pollute the presentation quality of steel member, the effect of slip casting is guaranteed in the normal operation of the exhaust that helps again simultaneously being in the milk, and raises the efficiency and the jacking quality of concrete.
The utility model is achieved in that
The exhaust plant of a kind of steel pipe column concrete jacking, described steel pipe column top sidewall is provided with vent, it comprises that also an end has the steel pipe of screw thread, and the end that this steel pipe does not have screw thread is welded on the sidewall of steel pipe column top, and the other end has the rubber tube on vertical ground by screwed connection.
The utility model mainly is made of one section threading steel pipe, rubber tube, and an end that is not with screw thread is welded on the steam vent of pillar near the shoulder beam, the steel pipe of rubber tube in threading connected, regulate the contact surface and the subsides power of steel pipe, rubber tube, steel pipe, rubber tube are closely connected.When the concrete grout liquid pump was raised to the top, the unnecessary concrete slurry that overflows will flow out along the rubber tube of steam vent, drains into ground.Successfully solved concrete slurry and flow out to have polluted steel member problem, after this device of presentation quality of having guaranteed the steel member is in time cleared up, can repeatedly recycle from steam vent, economical with materials greatly, and convenient and swift.
Description of drawings
Below, further specify the specific embodiment of the present utility model in conjunction with the accompanying drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is described threading steel pipe schematic diagram.
The specific embodiment
As Fig. 1 and referring to shown in Figure 2: the exhaust plant of a kind of steel pipe column concrete jacking, described steel pipe column 1 top sidewall is provided with vent 2, it comprises that also an end has the steel pipe 3 of screw thread 31, the end that this steel pipe 3 does not have screw thread is welded on the steel pipe column top sidewall 2, and the other end is connected with the rubber tube 4 on vertical ground by screw thread 31.
Claims (1)
1. the exhaust plant of steel pipe column concrete jacking, described steel pipe column top sidewall is provided with vent, it is characterized in that, it comprises that also an end has the steel pipe of screw thread, the end that this steel pipe does not have screw thread is welded on the sidewall of steel pipe column top, and the other end has the rubber tube on vertical ground by screwed connection.
