Description

Screw hole plugging structure

Technical Field

The utility model belongs to the building construction field especially relates to a screw rod hole block structure.

Background

High-rise buildings are more and more, and when the concrete shear wall is fixed by using a template in the building industry, a fixing device is needed, so that a wall-penetrating bolt, namely the wall-penetrating pull rod fastener, is needed. The construction team is a normal construction process when a shear wall is constructed, and the use of the through-wall bolt is a conventional measure of a construction unit, so that the bolt hole is reserved on the surface of the wall body after the construction of workers is finished.

The screw hole is not sealed, and the risk of outer wall leakage is generated. The most original treatment mode is that when inner and outer walls are painted, mortar is added into the screw hole, but the middle part of the screw is hollow, cracks are easy to generate, the screw hole cannot be sealed for a long time, and the outer wall leakage risk is extremely high. In order to solve the problem, most construction companies adopt a screw hole plugging method in which cement mortar, foaming agent, waterproof paste and the like are filled in a screw hole. The middle part of the screw is filled by the filling modes, so that the probability of cracks generated by blocking mortar is reduced, but the existing filling modes can not ensure the compactness of fillers in a screw hole, can not resist higher water pressure, have common water seepage prevention quality, can generate a leakage phenomenon after being used for a long time, and increase the repair time and cost.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art exists not enough, has solved current screw hole shutoff mode, can not resist higher water pressure, the general problem of antiseep quality aims at providing a screw rod hole block structure, and this structure adopts polyphenyl voussoir to glue polyurethane and glues and fill the screw rod hole, and operation process is simple and easy, the low price, and convenience saved time.

In order to solve the technical problem, the utility model discloses a technical scheme does: the utility model provides a screw rod hole block structure, includes wall body and screw rod hole, and the screw rod hole link up whole wall body, the whole shape in screw rod hole is the wedge, and wall body outside entrance to a cave area is greater than inboard entrance to a cave area, and the screw rod hole middle part is inlayed and is equipped with polyphenyl voussoir, closely laminates after bonding through the polyurethane layer between polyphenyl voussoir lateral surface and the screw rod hole medial surface, and the both ends packing of polyphenyl voussoir has the cement mortar layer, cement mortar layer and wall body surface parallel and level, sets up the polyurethane dope layer between cement mortar layer and the polyphenyl voussoir, and the wall body lateral surface.

The polystyrene wedge block is made of a polyethylene foam rod.

The distance between the end face of the polyphenyl wedge block and the side face of the wall body is 24-26 mm.

The polyurethane coating layer is a three-layer heterochromatic polyurethane waterproof coating layer with the thickness of 1 mm.

The cement mortar layer adopts dry and hard cement mortar.

Compared with the prior art, the utility model following beneficial effect has: the utility model is used for the polyphenyl voussoir of filling can be processed into the shape that needs in advance, and during high altitude construction shutoff screw hole, directly fill in the screw hole. Compared with the existing mode of filling foaming glue and waterproof factice, the method has the advantages of simple and easy operation process, low price, time saving, convenience, cost reduction and efficiency improvement.

In addition, the inner wall of the screw hole is smooth and flat and can be tightly connected with the polyphenyl wedge block, the polyphenyl wedge block is tightly jointed, one end of the screw hole is flushed by water through a water pipe, water cannot permeate, polyurethane is adhered, the polyphenyl wedge block is more tightly filled in the screw hole, the waterproof effect is greatly improved, the compacting effect is good, higher water pressure can be resisted, the leakage phenomenon after the screw hole of the outer wall is plugged is effectively avoided, the screw hole is in place once, and later-stage owner complaints and maintenance cost are greatly reduced.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a partially enlarged view of a portion a in fig. 1.

In the figure: the concrete wall comprises a 1-bit wall body, 2 screw holes, 3 polyphenyl wedges, 4 cement mortar layers, 5 polyurethane layers and 6 polyurethane coating layers.

Detailed Description

As shown in fig. 1-2, a screw hole plugging structure comprises a wall body 1 and a screw hole 2, wherein the screw hole 2 penetrates through the whole wall body 1, the whole shape of the screw hole 2 is wedge-shaped, the area of an outer side opening of the wall body 1 is larger than that of an inner side opening, a polyphenyl wedge block 3 is embedded in the middle of the screw hole 2, the outer side surface of the polyphenyl wedge block 3 is tightly attached to the inner side surface of the screw hole 2 after being bonded through a polyurethane layer 5, cement mortar layers 4 are filled at two ends of the polyphenyl wedge block 3, the cement mortar layers 4 are flush with the surface of the wall body 1, a polyurethane coating layer 6 is arranged between the cement mortar layers 4 and the polyphenyl wedge block 3, and a waterproof coating layer is coated.
