Description
Technical field
The utility model relates to and is used for the concrete check device that steel column pours in down a chimney pouring concrete construction in a kind of building operations.
Background technology
The concrete pile that adopts steel column to pour in down a chimney concrete pouring mode construction of buildings is a kind of job practices commonly used at present.The concrete materials that mixes is poured in the building pile steel pipe of erect in the mode of pushing tow from bottom to top by pressurized delivered equipment, and its advantage is to need not to vibrate effectively to avoid existing the problem in bubble cavity in the concrete pile of being poured into a mould.For solving the concrete materials poured into a mould in the steel pipe behind the casting complete when removing conveying equipment, released by the mouth of pipe backflow of former cast feed pipe under the self gravitation effect, non-return mode commonly used at present is to beat the wedge jack and insert the wedge stake therein to stop concrete backflow with interleaved mode at the duct wall position of feed pipe.The construction practice result shows that it is relatively poor that this wedge is inserted the effect that seals the non-return mode.Because its structure is complicated, at the required precision height that intersects when splitting the wedge jack, execute-in-place inconvenience, operating efficiency are low, materials when not only having increased operation and recruitment cost and uneconomical, and after concrete casting, also exist blocking-up to seal tight inadequately situation, still have a small amount of concrete grout backflow leakage inevitably, therefore seal the weak effect of non-return.
The utility model content
Given this, the utility model will provide a kind of concrete check device that steel column pours in down a chimney pouring concrete construction that is used for, thoroughly to address the above problem.
The utility model is used for the concrete check device that steel column pours in down a chimney pouring concrete construction, can be connected with the nozzle flange of concrete conveying pipe, and have on the width greater than the concrete conveying pipe caliber, on the substrate greater than the rectangle work area of 2 times of concrete conveying pipe calibers on the length, length direction one side in its rectangle work area is provided with the through hole that adapts with the concrete conveying pipe caliber, length direction opposite side in the rectangle work area is the block face that is used for the closed concrete conveyance conduit, and the position between through hole and block face is provided with the hole that is connected that adapts with said concrete conveying pipe nozzle flange bolt hole at least.
This substrate in the said structure should have under the prerequisite of said this work area size at least, and the global shape of this substrate can be selected as required, as rectangle, square, polygon, circle or ellipse etc.
The mode of occupation of the utility model said apparatus when steel column pours in down a chimney pouring concrete construction is: carry out pushing tow when pouring in down a chimney fluid concrete in steel column, said apparatus is placed between the abutted flange of conveyance conduit between concrete conveying equipment and steel column and with its firm connection, make this through hole on the substrate be between the flange docking site simultaneously and aim at the mouth of pipe, to guarantee concrete normal conveying; After cast finishes, this the block face on the substrate is transferred to the place, docking site of nozzle flange with external force, with the blocking-up pipeline, and through the hole that is connected therebetween substrate and steel column side charging nozzle flange are interconnected with suitable mode, just the bypass outlet block of steel column inner concrete is lived, promptly can remove conveying equipment safely afterwards.
In above-mentioned concrete check device, be used for the connecting hole that the nozzle flange with concrete conveying pipe is connected on the said substrate, should be provided with the former connecting hole on the flange under the situation that the position adapts, except that adopting on the substrate corresponding periphery of said this through hole and block face to be provided with respectively the hole that is connected for its use, when adopting as length/width than the particular form rectangular substrate that is 2/1, be arranged between said through hole and the block face this hole that is connected, can also be adopted as the form in the two shared one group hole that is connected that is connected with flange, structure is more simplified by it.When adopting the former mode that this is set to be connected the hole, the operation of after above-mentioned concrete pouring finishes the block on the substrate being shifted towards the nozzle flange docking site can realize by the translation mode that makes substrate; When adopting latter's mode that this is set to be connected the hole, concrete pouring finishes the back except that the block face that can adopt same parallel-moving type with substrate is transferred to place, nozzle flange docking site, can also adopt the rotating manner of the shared connecting hole of the two to realize and the transfer of this desired position around it, can increase the more selectivity of mode of operation in the construction, enlarge the flexibility that is suitable for.
Result of the test shows that the non-return of the above-mentioned check device of the utility model is satisfactory for result, and is easy to operate in the construction, helps improving the pouring concrete construction quality, and it is simple in structure, is easy to apply.
Below, foregoing of the present utility model is described in further detail again by the specific embodiment by the accompanying drawing illustrated embodiment.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
