Description
Technical Field
The utility model belongs to the technical field of the stagnant water screw rod, concretely relates to five section formula stagnant water screw rods.
Background
The water stop screw is generally used in the cast-in-place concrete construction process of buildings, and has the functions of fixing a template, controlling the concrete pouring thickness, stopping water and the like. The existing water stop screw rods are divided into a straight-through water stop screw rod and a three-section water stop screw rod, wherein the straight-through water stop screw rod and the three-section water stop screw rod are further divided in more detail, if the straight-through water stop screw rods are classified according to screw teeth, the straight-through water stop screw rods can be divided into a middle-tooth water stop screw rod, a fine-tooth water stop screw rod and the like, after construction is finished, two ends outside a wall need to be cut, the middle section is remained in the wall, and the straight-through water stop screw rods or the three-section water stop screw rods are upgrading products of wall-penetrating screw rods, have water stop and water prevention functions, and play a role in fixing a template to prevent mold explosion when a concrete wall body is poured.
The three-section type water stop screw mainly comprises an inner rod, outer rods, a connecting nut and the like, wherein water stop sheets are welded on the inner rod and are left in a wall body to achieve a water stop effect, the outer rods can be detached for reuse, the three-section type water stop screw can be divided into a sleeve type three-section type water stop screw, a cone type three-section type water stop screw, a hollow three-section type water stop screw and the like, in the construction process, two outer rods of the three-section type water stop screw can be detached easily, the step of cutting two ends outside the wall by the through type water stop screw is omitted, zero loss is caused to the template, the template is saved, and the purchase cost is saved.
However, the following problems exist in the detachable split screw rod of patent publication No. 202483175U or the three-section water-stopping screw rod or the straight-through water-stopping screw rod of the prior art: (1) The end of the three-section water stop screw is not limited, the mountain-shaped clamp, the fixing buckle and the like at the end are easy to lose, and the material loss is large; (2) The rubber cup on the three-section water stop screw is not limited, so that the rubber cup is easy to deflect and deform in the concrete vibrating process, and the quality and the impression of the inner side wall, the outer side wall and the inner side wall of the concrete are influenced; (3) the waterproof performance cannot meet higher requirements; therefore, the water-stopping screws cannot be applied to special scenes, such as construction sites of the clear water concrete, the clear water concrete is an expression technique of modern architecture, the clear water concrete is also called as decorative concrete due to a great decorative effect, and the basic idea is that after the concrete is poured, any material such as coating, tile pasting, stone pasting and the like is not needed, the expression technique of the concrete is a plain technique, the clear water concrete does not have other decorative materials, so that the resistance to wind and rain needs to pay great attention to the regulation of the reinforced concrete in the construction specification, and the three-section water-stopping screw or the straight-through water-stopping screw in the prior art is not applicable to the construction of the clear water concrete due to the problems of no limit to a rubber cup, no waterproof performance and the like, and the outer screw of the three-section water-stopping screw in the prior art is generally preset, so that the construction thickness needs to be changed in the construction process, and the embarrassment that the length of the outer screw is not enough occurs.
