Abstract
The utility model relates to a screw-fixing device for a building shear wall apparatus, comprising a fastener and an iron gasket. The utility model is characterized in that the fastener comprises inner and outer two sections, and is provided with a built-in fastener (31) and two built-out fasteners (35); both ends of the built-in fastener (31) are connected respectively with the built-out fasteners (35) through a hexagonal nut (34) with a flange, and a cone-shaped nut cap (33) is sheathed outwards on the hexagonal nut (34) with the flange. The utility model has the advantages of low cost, convenient arrangement, easy disassembly, repeated use and anti-leaky performance, and can improve the intensity of the shear wall.
Description
One, technical field
The utility model belongs to building field, refers more particularly to a kind of building shear wall screw fastening device.
Two, background technology
The shear wall securing member of Cai Yonging mainly contains dual mode in the market:
(1), as shown in Figure 1, directly pass shear wall with reinforcing bar 11 in the shear wall, welding iron plate 13 is used for waterproof and anti-skidding on the reinforcing bar, has two block concrete cushion blocks 12 on the reinforcing bar in order to locating template, and concrete pouring is between two templates.After treating wall concrete setting moulding, after taking template apart, this reinforcing bar is fixed within the walls whole, to expose the securing member reinforcing bar at the body of wall two ends, the weak point of this mode is: cost height (whole reinforcing bar is wasted entirely), the reinforcing bar that expose at while body of wall two ends easily gets rusty in the future and rain leakage takes place.
(2), as shown in Figure 2, fixing with the reinforcing bar 21 of an overcoat pvc pipe 22 when the template of fixing shear wall, after body of wall solidifies, whole reinforcing bar can be extracted out.Its weak point is: can stay many through holes on body of wall after the form removal, will influence the intensity of shear wall, wall leakage easily takes place simultaneously.
Three, the utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of cost low, is convenient to install, and is quick detachable, can use antiseepage and can improve a kind of shear wall screw fastening device of shear wall intensity repeatedly.
The utility model reaches in the following way, and as shown in Figure 3, the utility model is mainly interconnected by built-in firmware, tapered cup nut overcoat, flanged (FLGD) hex nut, external firmware, iron gasket and clamp nut and forms.Wherein, tapered cup nut overcoat diameter is inner small and outside big, is socketed with flanged (FLGD) hex nut in it, forms tapered cup nut.Be provided with built-in firmware in shear wall, and tapered cup nut, two ends, the tapered cup nut outside are the typified form of shear wall, this typified form by about each iron gasket maintenance of one, iron gasket is located on the external firmware, this iron gasket is fixed by firm nut.After treating that shear wall solidifies, can pull down clamp nut, iron gasket, external firmware, tapered cup nut successively, only stay one section built-in firmware in body of wall.So promptly can not stay through hole and shear wall both sides in body of wall can exposed steel bar, whole firmware (built-in firmware, external firmware) all can not stayed in the body of wall, and the other parts of this device can be used as required repeatedly yet.Convenient in practice of construction, quick, improve workmanship, and greatly reduce cost.

Five, the utility model embodiment
Embodiment of the present utility model now is described in detail in detail in conjunction with the accompanying drawings: as shown in Figure 3, the utility model mainly is made of 31 1 in built-in firmware, 2 in tapered cup nut overcoat, 2 of flanged (FLGD) hex nuts, 2 in external firmware, 2 of iron gaskets, 2 of clamp nuts.Wherein built-in firmware 31 is located in the shear wall, and the intermediate portion is slightly thin, plays anti-skidding function, with water proof rubber circle 32, plays the function of waterproof on it; Built-in firmware 31 links to each other with flanged (FLGD) hex nut 34 respectively by the screw thread at two ends; Hex nut 34 overcoats are in the tapered cup nut overcoat 33 of high density nylon casting processing (as Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, shown in Figure 9); The outside at the female overcoat of two tapered cup nuts all is connected with an external firmware 35, and external firmware 35 is an elongated rod shape, which is provided with an iron gasket that can move freely 36, is provided with clamp nut 37 in the outside of iron gasket 36.
When reality is used, built-in firmware 31, water proof rubber circle 32 and tapered cup nut overcoat 33 all are located in the shear wall, spacing between two tapered cup nut overcoats outside is the thickness of shear wall, the template of body of wall inwardly is locked through iron gasket, after treating that shear wall solidifies, can pull down clamp nut 37 successively, iron gasket 36, external firmware 35, because the shape of tapered cup nut overcoat 33 is tapers, its diameter is inner small and outside big, be socketed with hex nut 34 in it, the two can be integrated, can be directly outside turn hex nut 34, whole tapered cup nut overcoat 33 is removed in the lump together with the hex nut in it 34, finally in shear wall, only leave one section built-in firmware 31, and other parts can be recycled all.In body of wall, promptly can all not stay whole firmware in devices in the body of wall like this, can in body of wall, not stay through hole yet, just stay a bit ofly in body of wall, can reduce cost greatly on the one hand, can improve the intensity of body of wall on the other hand, in the middle of construction, also be convenient to operation simultaneously.So the utility model is a kind of desirable shear wall fastener for building.
