Embodiment 1
[0038] Such as figure 1 As shown, Embodiment 1 of the present invention provides a method for producing a core-pulling hollow plate under a vertical mold, comprising the following steps:
[0039] Arrangement of steel bars: Arrange the grid structure of steel bars to be poured in the mold car;
[0040] Inserting the inner core tube: the inner core tube includes the main core tube 7 and the auxiliary core tube 8 which are set independently, and the auxiliary core tube 8 and the main core tube 7 are inserted from the bottom of the mold car into the mold car with a steel structure grid;
[0041] Pouring: pour the material into the mold car, insert and tamp it, and form the board;
[0042] Pulling out the inner core tube: successively pull out the main core tube 7 and the auxiliary core tube 8 in the plate body to form a hollow plate;
[0043] Opening the mold and releasing the board: the mold car is removed to make a hollow board.
[0044] In this method, the hollow slab is pou...
Embodiment 2
[0047] Such as figure 1 As shown, this embodiment is partly the same as the above-mentioned embodiment 1, that is, it also includes the steps of arranging steel bars, inserting the inner core pipe, pouring, drawing the inner core pipe, and opening the mold and releasing the board; the difference is that after the pouring is completed, the inner core pipe is drawn Carry out pre-curing before, and the specific method of pre-curing is: send the poured mold car into the pre-curing warehouse, and perform curing at a temperature of 35-50°C and a humidity of 25-40% to achieve the required temperature of the core-pulling tube. required strength. Certainly, in order to be able to pull out the core-pulling tube, the temperature can be adjusted as required, and the present invention is not limited to this range of temperature or humidity. After the inner core tube is drawn, the molded board is cured before the mold is opened and the board is released. The specific method of curing the m...
Embodiment 3
[0049] Such as Figure 2-7 As shown, a production device for core-pulling hollow slabs under a vertical formwork includes a support 1, on which a track group is arranged, and the track group is connected with a mold car 2 for moving on the support 1;
[0050] The track group comprises parallel first track 3 and second track 4, and the two ends of first track 3 and second track 4 are communicated by ferry car, and model car 2 moves circularly on first track 3 and second track 4, here The limited movement can be sliding, as long as it can move, not limited to sliding;
[0051]The first track 3 or the second track 4 is equipped with a station for arranging steel bars, a station for inserting core tubes, a platform for distributing materials, a station for pulling out inner core tubes, and a station for opening molds and releasing panels;
[0052] The core tube entry station is set on the second rail 4, and the core tube entry station includes the auxiliary core tube entry statio...
