Detailed Description

As shown in fig. 1-2, a post-cast strip formwork system with convenient construction comprises a formwork 2 horizontally arranged under a post-cast strip, pre-embedded hard pipes 1 embedded in concrete at two sides of the post-cast strip, and an integrated supporting and protecting plate 3 arranged below the formwork 2 by being attached to the formwork 2; the integrated supporting and protecting plate 3 is provided with opposite-pulling screw rods 4 which are in one-to-one correspondence with the embedded hard pipes 1; note that the position of the counter-pulling screw rod 4 is aligned with the embedded hard pipe 1;

the embedded hard pipe 1 is embedded in concrete on two sides of the post-cast strip during pouring, and the upper end and the lower end of the embedded hard pipe are open and are respectively flush with the upper surface and the lower surface of the concrete at the embedded position; so as to form a vertical hole for penetrating the counter-pull screw rod 4, a common polyethylene white pipe in construction can be selected as the embedded hard pipe 1, and the inner diameter of the embedded hard pipe 1 is larger than the larger diameter of the counter-pull screw rod 4 so as to prevent the counter-pull screw rod 4 from being difficult to enter the pipe during traction; paying attention to the fact that a hose is not selected, the hose deforms when concrete is poured, and the opposite-pulling screw rod 4 cannot penetrate through the hose;

the integrated supporting and protecting plate 3 supports the bottom of the template 2 in the traction process, so that the template is prevented from deforming, and the integrated supporting and protecting plate can not be scattered like a conventional steel pipe back ridge supporting and protecting frame.

The lower end of the counter-pull screw rod 4 is fixedly connected with the integrated supporting and protecting plate 3, the upper end of the counter-pull screw rod penetrates through the template 2 upwards and then penetrates through the embedded hard pipe 1, and the counter-pull screw rod is locked by a nut after penetrating through the embedded hard pipe 1;

the upper end of the counter-pulling screw rod 4 is bound with a traction rope 5 for drawing the counter-pulling screw rod 4 from the base surface to the installation position.

The integrated supporting and protecting plate 3 can be made of a profiled steel plate, and the wavy edges of the profiled steel plate are respectively arranged on two sides of the post-cast strip; steel sheets or wood grid plates may also be used. The profiled steel sheet and the steel basketry sheet are durable but expensive, the wood grid plate is cheaper, and the wood grid plate can be assembled by using waste wood on a construction site, but is not durable. The integrated supporting and protecting plate 3 in this embodiment is a wood grid plate.

The nut pad 41 is arranged below the nut at the upper end of the counter-pulling screw rod 4 in a pad mode, the nut pad 41 is a steel disc with the thickness not smaller than 1 centimeter and the diameter not smaller than 10 centimeters, the nut pad 41 bears large pressure, and the pressure is dispersed to the concrete on the two sides of the post-cast strip, so that the concrete is prevented from being damaged by pressing.

The counter-pulling screw rod 4 is a full-thread screw rod, so that the counter-pulling screw rod can adapt to concrete with different thicknesses.

A rope tightener 51 is respectively arranged above the concrete on two sides of the post-cast strip, and the free end of the traction rope 5 positioned on the same side of the post-cast strip is bound on the rope tightener 51 on the side, so that the formwork can be supported by only two workers. Note that this way of tightening the rope may cause the opposite-pulling screw 4 to be unable to smoothly enter the pre-buried hard tube 1, and the rope tightener 51 should be anchored on the concrete when in use and be higher than the upper end of the opposite-pulling screw 4, so that when the worker tightens the pulling rope 5 with one hand, the worker can adjust the position of each pulling rope 5 with the other hand, so that the opposite-pulling screw 4 smoothly enters the pre-buried hard tube 1. Of course, the lower end of the embedded hard pipe 1 can be made into a bell mouth with an opening gradually increased, so that the tension screw rod 4 can enter the embedded hard pipe 1, and a worker can hold the rope tightener 51 by hand without anchoring. The cord tightener 51 is preferably a ratchet type cord tightener 51 with a self-locking feature, so that after the pull screw 4 is pulled up, the nut can be screwed by freeing up the hand. Of course, if there is only one pull line 5 on each side of the post-cast strip, the use of the rope tightener 51 is not necessary.

The utility model relates to a convenient post-cast strip template system of construction, its use includes following step:

step one, when concrete on two sides of a post-cast strip is poured, embedding the embedded hard pipe 1;

step two, assembling the template 2, the integrated supporting and protecting plate 3 and the opposite-pulling screw rod 4 into a whole on a base surface;

step three, after the concrete on the two sides of the post-cast strip is solidified, anchoring the rope tightener 51 above the concrete on the two sides of the post-cast strip, and then binding the traction rope 5 on the rope tightener 51;

step four, hanging the traction ropes 5 from the corresponding embedded hard pipes 1 and binding the traction ropes on the corresponding counter-pulling screw rods 4;

and step five, tightening the traction rope 5 to enable the opposite-pulling screw rod 4 to be installed in place, and then installing the nut cushion disc 41 and the nut.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
