Description

Waterproof block structure of wall screw rod

Technical Field

The utility model belongs to the technical field of concrete wall body water repellent, concretely relates to carry out waterproof shutoff's block structure to wall screw rod.

Background

At present, in building construction, after a concrete shear wall column or a frame structure shown in fig. 1 is completed, a screw head of a through-wall screw is flush with the wall surface of a concrete wall body in a plane cutting mode only by processing a tension screw left at an outer wall, and excessive waterproof processing is not performed any more. This causes the problem that the wall body seeps water in the later period due to the oxidation of the screw rod. After the water seepage condition appears, even later stage rethread stopper crack is repaired also in no matter, can not effectively solve the infiltration problem of wall body.

Disclosure of Invention

Not enough to prior art, the utility model aims at providing a wear the wall screw rod to concrete wall body and carry out waterproof block structure of waterproof shutoff.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a through-wall screw waterproof plugging structure comprises a concrete wall body and a through-wall screw, wherein the end plane of the through-wall screw is cut to be flush with the wall surface of the concrete wall body, the end part of the through-wall screw is rotatably cut to penetrate into the concrete wall body, a hole is formed in the wall surface of the concrete wall body and positioned outside the screw head of the through-wall screw, an antirust paint layer is uniformly coated on the screw head, the hole is filled by inorganic siliceous waterproof mortar, the outer surface of the inorganic siliceous waterproof mortar is coated with inorganic siliceous cement-based capillary crystals, and the inorganic siliceous cement-based capillary crystals cover the wall surface at the periphery of the hole.

The end part of the through-wall screw after plane cutting is rotatably cut, so that the screw head is deeply hidden in a wall body to avoid oxidation caused by direct contact of the screw head and air, meanwhile, an antirust paint layer is used for carrying out secondary protection on the screw head to prevent the screw head from being rusted, inorganic siliceous waterproof mortar is used for filling holes on the outer side of the screw head, and inorganic siliceous cement-based infiltration crystals are coated on the outer surface of the inorganic siliceous waterproof mortar, so that the inorganic siliceous waterproof mortar and the inorganic siliceous cement-based infiltration crystals have good functions of water seepage prevention and micro-crack repair, and the screw head is sealed in the wall body, thereby effectively solving the problem that the screw head is exposed to cause water seepage of the wall body due to oxidation, and simultaneously, the internal structure of the wall body cannot be damaged.

As a preferred scheme, the end part of the through-wall screw is rotary-cut to penetrate into the concrete wall body by 1cm, conical holes are formed on the wall surface of the concrete wall body, and the painting thickness of the inorganic siliceous cement-based permeable crystallization is 2 mm.

The utility model discloses following beneficial effect has:

the utility model discloses wear waterproof block structure of wall screw rod, its tip through the screw rod of wearing after the plane cutting carries out the rotary-cut, make its screw head go deep into to hide in the wall body and avoid screw head direct and air contact oxidation to appear, carry out secondary protection to the screw head by the anti-rust paint layer simultaneously and prevent its corrosion, fill the hole in the screw head outside by inorganic siliceous waterproof mortar, and apply paint inorganic siliceous cement base infiltration crystallization with a brush in inorganic siliceous waterproof mortar's surface, inorganic siliceous waterproof mortar and inorganic siliceous cement base infiltration crystallization have good prevention of seepage water and repair microcrack's function, thereby seal the screw head in the wall body, both solved the problem that the screw head exposes because of the oxidation leads to the wall body infiltration effectively, can not destroy wall body inner structure simultaneously.

Drawings

FIG. 1 is a diagram of a concrete shear wall column or frame structure;

fig. 2 is the utility model discloses the waterproof block structure's of wall screw schematic diagram.

In the figure: 1. a concrete wall; 2. a through-wall screw; 3. a screw head; 4. a hole; 5. a rust-proof paint layer; 6. inorganic siliceous waterproof mortar; 7. and (3) carrying out inorganic siliceous cement-based infiltration crystallization.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments so as to more clearly understand the technical idea claimed in the invention.

As shown in fig. 2 the utility model discloses wear waterproof shutoff structure of wall screw rod, including concrete wall 1 and wear wall screw rod 2, the tip plane cutting of wearing wall screw rod 2 and concrete wall 1's wall parallel and level, the degree of depth that the tip rotary-cut of wearing wall screw rod 2 deepened concrete wall 1 is about 1cm and lie in the screw head 3 outside of wearing wall screw rod 2 on concrete wall 1's wall and form conical hole 4, screw head 3 evenly coats and has anti-rust paint layer 5, hole 4 is filled and led up by inorganic siliceous waterproof mortar 6, and apply paint inorganic siliceous cement base infiltration crystallization 7 on the surface of inorganic siliceous waterproof mortar 6 with a brush, inorganic siliceous cement base infiltration crystallization 7 covers the peripheral wall in the entrance to a cave of applying paint in hole 4 simultaneously, this inorganic siliceous cement base infiltration crystallization 7 apply paint thickness with a brush about 2 mm. The depth of the end part of the through-wall screw 2 extending into the concrete wall 1 in a rotary cutting manner is not fixed, and the water seepage prevention requirement can be met only by about 1cm deep in the rotary cutting manner, and meanwhile, the workload of the rotary cutting operation can be saved. In addition, other hole shapes are not excluded as regards the specific shape of the holes 4.

The utility model discloses a carry out the rotary-cut to the tip of the screw rod 2 that wears after the plane cutting, make its screw head 3 go deep into to hide in the wall body and avoid screw head 3 direct and air contact and oxidation appear, carry out the secondary protection by anti-rust paint layer 5 to screw head 3 simultaneously and prevent its corrosion, fill the hole 4 in the 3 outsides of screw head by inorganic silicon waterproof mortar 6, if necessary in the actual construction, need clean up the peripheral residual mortar of punchhole or water the moist so that the mortar is more compatible with former wall body to the punchhole periphery. The inorganic silicon waterproof mortar 6 and the inorganic siliceous cement-based osmotic crystal 7 belong to the prior art, can be directly purchased and obtained on the market, have good water seepage prevention and the function of automatically healing microcracks below 0.4mm, the inorganic silicon waterproof mortar 6 can adopt inorganic siliceous structural self-waterproof mortar produced by Source Water communications corporation, the mortar is composed of cement, yellow sand and waterproof agent prepared by taking high-quality obsidian or natural zeolite as main raw materials, the inorganic siliceous cement-based osmotic crystal 7 can adopt cement-based osmotic crystal type waterproof coating prepared by taking high-quality obsidian or natural zeolite as main raw materials produced by Source Water communications corporation, the selection of the specific inorganic silicon waterproof mortar 6 and the inorganic siliceous cement-based osmotic crystal 7 can be determined according to requirements, thereby the screw head 3 is sealed in the concrete wall body 1, the problem that the screw head 3 is exposed to cause the water seepage of the wall body due to oxidation is effectively solved, meanwhile, the internal structure of the wall body cannot be damaged.
