Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
The stake core concrete moulding process that one embodiment of the invention provides, comprises the following steps:
(1) before filling concrete, guarantee that reinforcing cage is not contaminated, and to dispose bottom a core and sediment on retaining wall and ponding;
(2) according to stake core volume, the use amount of concrete is calculated;
(3) install special filling concrete device, the pump line of concrete pump is stretched in special filling concrete device and carry out filling concrete;
(4) concrete vibrated and flatten;
(5) carry out building maintenance, until final set in 8-24 hours after filling with concrete.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5.
Special filling concrete device used in the stake core concrete moulding process that one embodiment of the invention provides, the closing in assembly that it comprises funnelform enclosing 1 and is located at below enclosing 1, enclosing 1 upper port is square, lower port is rounded, certainly can also be other any suitable shapes, enclosing 1 upper end is provided with some handles 11, handle 11 is for this device of auxiliary operation, the lower end of enclosing 1 outer wall is provided with a circle flange 12, half ring flat-plate 21 that closing in assembly encloses ring by a pair horizontal positioned forms, the upper surface laminating flange 12 of these a pair half ring flat-plates 21, one end of these a pair half ring flat-plates 21 is hinged on the corresponding position of flange 12 respectively by jointed shaft 22, and these a pair half ring flat-plates 21 have the rotational freedom in horizontal plane, the locking mechanism making to fix is provided with between the two between the other end of these a pair half ring flat-plates 21, it is annular that these a pair half ring flat-plates 21 enclose formed ring, and with enclosing 1 lower port coaxial line, its annular distance diameter is less than the diameter of enclosing 1 lower port.
Described locking mechanism comprises two docking blocks 31 being separately fixed at the other end of these a pair half ring flat-plates 21 and two ends bearing pin 32 with limited step 321, docking block 31 to be connected with vertical plate 312 upwards by level board 311 and to form, two vertical plate 312 positions are corresponding, under the state that these a pair half ring flat-plates 21 are closed, two vertical plates 312 fit, the upper end of two vertical plates 312 has a notch 313, two notch 313 positions are corresponding, bearing pin 32 is connected in two notches 313, the limited step 321 at such bearing pin 32 two ends can limit this pair half rotations of ring flat-plate 21 in horizontal plane, thus maintain these a pair half ring flat-plates 21 at closure state.Certain described locking mechanism can also be other any suitable structures, as fastening piece, the hasp cooperatively interacted, bolt etc.
Whole device should adopt the large on-deformable material of intensity.
See Fig. 6, the using method of this special filling concrete device is: first exited by bearing pin 32, these a pair half ring flat-plates 21 are opened, then this special filling concrete device is placed on a round platform of core port 5 through reinforcing cage 4, for ease of penetrating of reinforcing cage 4, it is large that the size of the lower port of enclosing 1 will design, exactly because also this reason, the lower port of enclosing 1 is easy to produce gap with stake core mouth in rocking, thus cause spilling and the waste of concrete, the assembly that closes up then can address this problem, now, as long as these a pair half ring flat-plates 21 are closed into ring, then bearing pin 32 is installed, just be equivalent to by the size of enclosing 1 lower port become little as much as possible, not only gap can be eliminated, and can rock by anti-locking apparatus, thus ensure when filling with concrete, concrete can all enter in a core swimmingly, thus shorten construction period, artificial and material are saved, order pours dense, and avoid the waste of concrete.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.The annular distance shape enclosing institute Cheng Huan as these a pair half ring flat-plates is not restricted to annular, and in concrete enforcement, annular distance shape should be corresponding to the cross sectional shape of reinforcing cage.
