Abstract
The invention discloses a steel tube concrete member capable of conveniently removing core concrete. The operating method comprises the following steps: presetting a plastic film layer with water bubbles on an inner wall of a steel tube, and longitudinally presetting a pull rod of which one end is provided with hooks between the plastic film with water bubbles and the inner wall of the steel pipe; drawing the pull rod after the steel tube concrete member is used up when the core concrete needs to be removed, and allowing the hooks of the pull rod to scratch the water bubbles in the plastic isolation film. After the moisture in the water bubbles in the plastic isolation film is automatically released, a thin annular gap is formed between the inner wall of the steel tube and the core concrete, and the core concrete in the steel tube can be smoothly removed.
Description
Technical field
The present invention relates to a kind of steel pipe recycling technology of concrete filled steel tubular member, relate in particular to a kind of concrete filled steel tubular member that facilitates core concrete to remove.
Background technology
After concrete filled steel tubular member uses, how recycling is technological difficulties to steel pipe.
In prior art, general employing knocked core concrete, or the mode of holing on core concrete, removes core concrete.
At least there is following shortcoming in above-mentioned prior art:
Complicated operation, waste time and energy, conventionally have part concrete to be bonded on steel pipe inner wall, cannot thoroughly remove.
Summary of the invention
The object of this invention is to provide a kind of simple to operate, remove facilitate thoroughly core concrete remove concrete filled steel tubular member.
The object of the invention is to be achieved through the following technical solutions:
The concrete filled steel tubular member that facilitates core concrete to remove of the present invention, before filling concrete, at the preset one deck band of steel pipe inner wall bubble plastic foil, and described with bubble plastic foil and steel pipe inner wall between longitudinally preset one or more one end band hook the pull bar of thorn.
As seen from the above technical solution provided by the invention, what the embodiment of the present invention provided facilitate concrete filled steel tubular member that core concrete removes, due to before filling concrete, at the preset one deck band of steel pipe inner wall bubble plastic foil, and between with bubble plastic foil and steel pipe inner wall longitudinally preset one or more one end band hook the pull bar of thorn, after concrete filled steel tubular member is finished using, in the time that needs are removed core concrete, first drawing goes out pull bar, the hook of pull bar stings the bubble on scratching in plastic barrier film, after the bubble of plastic barrier film discharges moisture automatically, between steel pipe inner wall and core concrete, form a thin layer annulus, core concrete in steel pipe is removed smoothly.

Fig. 2 is tubulose band bubble plastic foil expanded view in the embodiment of the present invention;
Fig. 3 is the pull bar that in the embodiment of the present invention, band hooks thorn;
Fig. 4 is the decomposing schematic representation that facilitates the concrete filled steel tubular member of core concrete removal in the embodiment of the present invention;
Fig. 5 is the overall structure schematic diagram that facilitates the concrete filled steel tubular member of core concrete removal in the embodiment of the present invention.
Detailed description of the invention
To be described in further detail the embodiment of the present invention below.
Of the present invention facilitate core concrete remove concrete filled steel tubular member, its preferably detailed description of the invention be:
Before filling concrete, at the preset one deck band of steel pipe inner wall bubble plastic foil, and described with bubble plastic foil and steel pipe inner wall between longitudinally preset one or more one end band hook the pull bar of thorn.
Described is many strip bubbles along the circumferential direction with the bubble on bubble plastic foil.
Described many strip bubbles are along the circumferential direction divided into multistage in the longitudinal direction, form the multiple row bubble longitudinally distributing along described steel pipe, and every row bubble all arranges a pull bar.
Described, described with bubble plastic foil plastic foil be prefabricated into described steel pipe inner wall coincide tubular.
After concrete filled steel tubular member is finished using, in the time that needs are removed core concrete, first drawing goes out pull bar, the hook of pull bar stings the bubble on scratching in plastic barrier film, after the bubble of plastic barrier film discharges moisture automatically, between steel pipe inner wall and core concrete, form a thin layer annulus, the core concrete in steel pipe is removed smoothly.
The concrete filled steel tubular member that facilitates core concrete to remove of the present invention, can remove core concrete fast and effectively, reaches the object of steel pipe recycling, can quick, easy, efficiently remove core concrete.
Specific embodiment:
As shown in Figures 1 to 5, before empty steel pipe perfusion core concrete, first paste one deck plastic foil liners (this plastic foil liner contains bubble) at steel pipe inner wall, then again to penetration concrete in steel pipe.After concrete filled steel tubular member uses, in the time that needs are removed concrete, first puncture bubble by a certain device, just can discharge " mezzanine space " between core concrete and steel pipe inner wall, also just eliminate steel pipe and concrete bonding, just can remove easily core concrete.
The device that specific embodiment relates to comprises:
(1) tubulose bubble plastic foil:
As shown in Figure 1 and Figure 2, be attached to steel pipe wall in this plastic foil, on it, annular is evenly distributed with bubble.Bubble is strip along the circumferential direction, for preventing that, in actual mechanical process, bubble breaks, bubble can be divided into multistage (as more than 3 sections), even if indivedual like this bubble breaks, does not affect overall result of use.For film is arranged into steel pipe inner wall easily, plastic foil is prefabricated into tubular, and plastic foil is attached to steel pipe inner wall.
(2) bubble lancing device:
As shown in Figure 3, bubble lancing device is the pull bar that one end headband hooks thorn.Before filling concrete, this pull bar is arranged between steel pipe and plastic foil.There are several row bubbles, just several pull bars of corresponding layout.
(3) core concrete is removed technique:
In the time that needs are removed concrete, pull-out pull bar, and puncture each annular bubble, thus between concrete and steel pipe, forming space, concrete can take out easily.
The above; only for preferably detailed description of the invention of the present invention, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
Claims (5)
