Example 2

With the attached drawings 1-4, the utility model discloses concrete wall pouring template fixed water stop screw structure work progress and principle.

1) The limiting sleeves 2 fixedly arranged on the water stopping screw rods 1 are adjusted according to the design thickness of the concrete wall, the limiting sleeves 2 are symmetrically arranged towards two sides at the center parts of the water stopping screw rods 1, and the distance between the outer sides of the limiting sleeves 2 at two sides of the front end rod head 12 and the rear end rod head 13 is ensured to be the design thickness size of the concrete wall.

2) Laying a wall steel reinforcement framework according to the design position of a concrete wall on a construction site, fixedly erecting pouring templates 5 on two sides of the framework respectively, fixing the two templates 5 by laying and installing water stop screws 1, arranging the templates 5 on two sides of the wall in a contraposition mode, penetrating the front end rod head 12 and the rear end rod head 13 of each water stop screw 1 from the template screw through holes 53 on the templates 5 on two sides respectively, and jacking the templates 5 on two sides to the outer side position of the limiting sleeve 2.

3) From the outer sides of the two side templates 5, a template screw perforation backing plate 3 and a fastening screw thread 4 are respectively arranged on the front end rod head 12 and the rear end rod head 13 which penetrate out from the template screw perforation 53 in sequence, one side of the big circular end surface of the template screw perforation backing plate 3 with the template screw perforation clamp edge 32 is matched with the template screw perforation 53, the template screw perforation clamp edge 32 is arranged in the template screw perforation 53, the fastening screw thread 4 is adjusted to inwards press the template screw perforation backing plate 3, so that one side of the big circular end surface of the template screw perforation backing plate 3 is completely pressed on the template 5 at the position of the template screw perforation 53, and the template 5 does not transversely shake along the water stop screw 1 any more.

4) And (3) after the templates 5 are installed and fixed in the steps 1-3 at the root part, pouring concrete 6 between the templates 5 and vibrating and tamping the concrete to complete the concrete wall pouring operation.

5) After the concrete is completely solidified and solid, the fastening screw threads 4 are sequentially detached from the front end rod head 12 and the rear end rod head 13 of the water stop screw 1, then the template 5 is taken out from the front end rod head 12 and the rear end rod head 13 through the traditional modes of knocking, pulling and the like, and the template screw perforating base plate 3 is taken down from the water stop screw 1 together along with the removal process of the template 5 and then taken down from the template 5.

6) And (4) recovering and storing the detached template 5, the template screw punching base plate 3 and the fastening screw threads 4.

7) And (3) treating the concrete wall surface, cutting off and grinding the front-end rod head 12 and the rear-end rod head 13 of the water stop screw rod 1 extending out of the wall surface along the wall surface, and finishing the construction of the reinforced concrete wall body.

In the step 3) of the process, the large round end surface of the template screw perforation base plate 3 can increase the stress area of the template 5 at the template screw perforation 53, and the cone frustum structure can disperse the pressure conduction, thereby reducing the deformation of the template; the template punching clamping edge 32 of the template screw punching base plate 3 prevents the template screw punching 53 from directly contacting the water stop screw 1, and reduces the damage to the template screw punching 53 when the water stop screw 1 is pressed too much; as shown in fig. 4, the position of the water stop screw 1 is just located at the joint of the first formwork 51 and the second formwork 52 on the same side, and the large circular end face of the formwork screw perforation backing plate 3 fixes the first formwork 51 and the second formwork 52 on two sides through the surface, so that the joint of two adjacent formworks 5 can be better fixed, and the joint of the first formwork 51 and the joint of the second formwork 52 are kept flush. The template 5, the template screw perforating base plate 3 and the fastening screw thread 4 are effectively recycled for multiple times through the construction process step 6), only the water stop screw 1 is consumed in each construction, and the construction cost can be effectively reduced.
