[specific embodiment]
In the explanation of this specific embodiment, the shape of so-called soft form is meant that soft form is in the shape when charging gas or liquid condition.
Consult illustrated in figures 1 and 2ly, this soft form 10 includes that a cavity body 100 and is arranged on this cavity body 100 and first charges and discharge mouthfuls 110 with this cavity body 100 connects, and this first charges and discharge in mouthfuls 110 and be provided with one first valve 120.This cavity body 100 is to prepare such as soft materials such as flexible plastic, rubber coating clothes, more suitably be, this cavity body 100 and this first charge and discharge mouthfuls 110 both be smooth outer surface by the one-body molded external surface that should sky carcass 100 of soft material, when making cassette ceiling, it is fastening bonding that smooth external surface can avoid this soft form 10 and concrete to starch, thereby be convenient to take out after the cassette ceiling moulding this soft form 10; This first charge and discharge mouthfuls 110 for this cavity body 100 charge and discharge gas/liquid provides passage, this first valve 120 plays and discharges or seal the gas in this cavity body 100 or the effect of liquid.
The inner surface of the cavity body 100 of this soft form 10 is provided with hose set 130, and this hose set 130 is made up of at least one warp-wise flexible pipe 132 and at least one broadwise flexible pipe 134, and this warp-wise flexible pipe 132 connects each other with this broadwise flexible pipe 134.This hose set 130 and one is arranged at this and first charges and discharge second in mouthfuls 110 and charge and discharge mouthfuls 140 and connect and be connected, this second charge and discharge mouthfuls 140 for this hose set 130 charge and discharge gas/liquid provides passage, be provided with one second valve 150 in it, it is used to discharge/seal the gas/liquid in this hose set 130.
This cavity body 100 also is provided with at least one drag-line flexible pipe 160, one end of this drag-line flexible pipe 160 second charges and discharge mouthfuls 140 and is connected with this, the other end connects the effect that is connected this drag-line flexible pipe 160 with this hose set 130 two: when charging gas/liquid, can be embodied as this hose set 130 via this drag-line flexible pipe 160 and charge gas or liquid; After the cassette ceiling moulding and when taking out this soft form, but this this soft form 10 of drag-line flexible pipe 160 pull-ups is convenient to the disengaging of this soft form 10 and concrete.
When this soft form 10 is charged gas or liquid, can be earlier second charge and discharge mouthful 140 pairs of these hose set 130 and fill via this, and close this second valve 150 and seal gas or liquid in this hose set 130, and then first charge and discharge mouthful 110 pairs of these cavity body 100 and charge, and close this first valve 110 and seal gas or liquid in it via this.Be in when charging state, this hose set 130 is attached to the inner surface of this cavity body 100 crisscrossly, can increase the intensity of this soft form 10.
Consult Fig. 3 and shown in Figure 4, it is respectively schematic appearance and the cross-sectional schematic of another embodiment of soft form of the present invention.130 perforations of the hose set of this soft form 10 are connected with at least one column flexible pipe 170, and it cooperates with this hose set 130, play the effect that increases these soft form 10 intensity.The otherwise structure of this soft form is identical with the structure of the described soft form of a last embodiment.
Among above-mentioned two embodiment, soft form 10 is respectively spherical soft form and box-like soft form, this soft form can also be the soft form such as tubulose soft form regular shapes such as (with reference to figure 5 and shown in Figure 6), or erose soft form but apparently.
As shown in Figure 7, this support 20 is for having the tubular or the box-like frame members of the two ends perforation of sidewall 200 on every side, and its lower port extends internally and is formed with flange 210, and this flange 210 can be used for support hush panel or reinforced mesh.
In conjunction with Fig. 8 and shown in Figure 9, when utilization job practices of the present invention is made hollow cast slab, at first carry out formwork and mounting template 30 (step S100), this template 30 is fixed by supports support, and it can adopt timber shuttering, punching block or other composite shutterings.This template provides working platform for the making of hollow cast slab, and has stipulated the shape and the size of the cassette ceiling that will make simultaneously.
Place and colligation floor plate at the bottom of reinforcing bar 40 (step S101), when carrying out the arrangement of reinforcement of reinforcing bar and plate top reinforcing bar at the bottom of the plate, can carry out corresponding arrangement of reinforcement to the diverse location of cassette ceiling.
Place soft form 10 (step S102),, placement more accurate for the location that makes soft form operated more simple, in advance the position line of sign soft form on reinforcing bar at the bottom of soffit formwork or the plate.
Behind placement and colligation floor plate top reinforcing bar 50 (the step S103), put support 20, and make this support 20 be inserted in first of this soft form 10 to charge and discharge mouthful (a step S104), then this soft form 10 is charged gas or liquid, and fix this soft form 10 (step S105), the liquid that is charged can be water, oil, perhaps other liquid.The effect of this support 20 is to provide passage for the taking-up of soft form 10.
Water and smash concrete 60 and carry out maintenance (step S106), in watering the process of smashing concrete, note to prevent that the concrete slurry from flowing into this support 20, is not easy to the taking-up of this soft form 10 in order to avoid stop up this support 20.After treating that concrete reaches certain intensity, give off gas or liquid in the soft form 10, and take out soft form 10 (step S107) via support 20 places.After giving off the gas or liquid in the soft form 10, can pull first of this soft form 10 and charge and discharge mouth, this soft form 10 is separated with concrete 60, and take out via these support 20 places.For the ease of the disengaging of this soft form, in the process of construction, can be at the coated one deck release agent of the external surface of this soft form.
Place hush panel or reinforced mesh 70 in support 20 interior lower end, pour concrete (step 108) then, thus make this Drawing-Core hollow cast slab.Because this support 20 is less, also direct pour concrete and need not at support 20 places placement hush panel or reinforced mesh 70.
Consult Figure 10 and shown in Figure 11, with another embodiment of the job practices of hollow cast slab that utilizing soft carcass of the present invention is described.When making hollow cast slab, at first carry out formwork and mounting template 30 (step S200); Opening 80 (step S201) is set on template 30, this opening 80 is provided with according to the storing position of the soft form of being planned in advance, the quantity of the opening 80 of required setting determines that according to the quantity of the soft form of required placement a soft form need be provided with an opening; To should opening 80 placing racks 20 (step S202); Reinforcing bar 40 (step S203) at the bottom of placement and the colligation floor plate is placed soft form 10 (step S204) again, makes first of soft form 10 charge and discharge muzzle and goes into this support 20; Place and colligation floor plate top reinforcing bar 50 (step S205), then soft form 10 is charged gas or liquid, and fix this soft form 10 (step S206); Water and smash concrete 60 and carry out maintenance (step S207); After treating that concrete reaches certain intensity, give off gas or liquid in the soft form 10, and take out soft form 10 (step S208) via support 20 places; Place hush panel or reinforced mesh at support 20 places, pour concrete (step S209) then, thus make this Drawing-Core hollow cast slab.Other operations of present embodiment are identical with a last embodiment.
