Detailed Description
The following description of the technical solutions in the embodiments of the present utility model will be clear and complete, and it is obvious that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1
Referring to fig. 1, the pull rod for controlling the thickness of a concrete wall reinforcing steel bar protection layer provided by the utility model mainly comprises a wire screw 1, a nut 2, a protection layer reinforcing steel bar positioning part 3 and a protection layer template positioning part 4.
At present, the template is to drawing reinforcement and generally adopts logical silk screw rod 1, utilizes logical silk screw rod 1 to make reinforcement layer thickness controller can save cost and facilitate the use.
The protective layer steel bar positioning part 3 is fixedly arranged on the harness cord screw 1, clings to steel bars on the outer side of the wall in the formwork supporting process, and plays a role in positioning.
The protective layer template positioning part 4 is fixedly arranged on the harness cord screw 1, clings to the inner side of the template in the template supporting process, and plays a role in positioning the template.
The screw cap 2 is arranged outside the template, and the template is positioned between the screw cap 2 and the template positioning part 4 of the protection layer, so that the template is fixed in a pulling way.
Wherein, protective layer reinforcing bar location portion 3 and protective layer template location portion 4 all set up to the reinforcing bar, and its protective layer reinforcing bar location portion 3 and protective layer template location portion 4 are all welded on logical silk screw rod 1.
Specifically, the sheathing reinforcement positioning portion 3 and the sheathing form positioning portion 4 are reinforcement bars arranged in a cross-like manner. In the operation process, the protection layer steel bar positioning part 3 is clamped by utilizing the nut 2 to be matched with the steel bars at the outer side of the wall, and then the protection layer steel bar positioning part 3 is welded on the wire passing screw 1. At this time, the protection layer reinforcing bar positioning portions 3 on both sides are positioned in the length direction of the through-wire screw 1.
And then the position of the template at the outermost side of the length direction of the harness cord screw 1 is limited by using the nut 2, and then the template positioning part 4 of the protective layer is tightly attached to the template and then welded on the harness cord screw 1, so that the template positioning can be realized by matching with the nut.
The outside of the harness cord screw 1 is fixedly provided with a water stop ring 5, and the water stop ring 5 is a steel water stop ring 5. The inner side of the template can be provided with a water-swelling water stop ring 5 which mainly plays a role in water resistance.
