Abstract
The utility model discloses an embedded type embedded nut which comprises a metal nut (1) and a plastic fixing sleeve (2), the metal nut (1) is arranged inside the plastic fixing sleeve (2), wherein the metal nut (1) comprises a fixing seat (11) arranged at the top of a nut (103) and more than one through hole (102) formed in the fixing seat (11). The plastic fixing sleeve (2) is formed by integrating of a sleeve hole (202), cylindrical punched holes (201) arranged on the periphery of the sleeve hole (202) and a base (203), the nut (103) is embedded in the sleeve hole (202), positions of the cylindrical punched holes (201) correspond with the position of the through hole (102), and the fixing seat (11) is fit with the top ends of the cylindrical punched holes (201). Due to the fact that the nut (103) can be firmly embedded in the sleeve hole (202), a gravity center of the nut is reduced, and therefore the embedded type embedded nut is more stable in structure and suspension force of the nut is improved.
Description
Technical field
The utility model relates to embedded nut, relates in particular to a kind of embedded embedded nut for large-scale steel structure building or concrete steel building suspension heavy weight.
Background technology
In building operations, usually need to install unsettled pendant spare, furred ceiling, crane cable, ventilating duct etc., past mostly adopts in concrete pre-buried suspension hook or solves with the method that Churn drill is put into setscrew after to the concrete products punching, the shortcoming of these methods is to hang the pulling force deficiency, complexity is installed, and not attractive in appearance.A kind of concrete embedded nut is arranged in recent years, as shown in Figure 1, formed by top cover, nut, nut seat, during use, be embedded in advance in the concrete of cast, can be used for the unsettled hanging piece of hoisting large-size, but the center of gravity height of the concrete embedded nut of this kind, during connecting bolt, bolt inserts the plastic nut seat earlier, and then and nut screwing clamping.Because nut is too thin, bolt is not dark painstakingly, has influenced the bearing capacity of suspention; Bolt is easy to generate trickle rocking through higher plastic nut seat, makes the risk of bolt falling nut increase.This is fatal hidden danger for the embedded nut that is used for suspention; And this kind plastic nut holder structure complexity is to the manufacture process requirement height.
In view of above-mentioned present situation, a kind of concrete embedded nut need be provided, its manufacture craft is simple, institute's consumption material is few, center of gravity is low, the suspention ability is strong.
Summary of the invention
The required dissatisfied technical problem of determining of the utility model is: a kind of embedded embedded nut, not only simple in structure, reduce the nut center of gravity, and increase suspension force and embedded embedded nut.
Technical problem described in the utility model solves by following proposal: a kind of embedded embedded nut, comprise metal nuts and plastics fixed cover, and metal nuts places the plastics fixed cover, wherein,
Described metal nuts has the holder that is located at the nut top and be provided with more than one through hole on this holder;
Described plastics fixed cover constitutes one by trepanning, the cylindricality perforation that is located at the trepanning periphery and base, described nut embeds in the trepanning, through hole is corresponding with the cylindricality punch position, fits in the top of holder and cylindricality perforation, and is fastening from the cylindricality perforation of holder through hole and plastics fixed cover by nail.
On the such scheme basis, the through hole of described metal nuts circumferentially is evenly distributed on the holder, and corresponding one by one with the position of the cylindricality of plastics fixed cover perforation.
On the such scheme basis, the internal diameter of the nut external diameter of described metal nuts and the trepanning of plastics fixed cover coupling.
The utility model superiority is: because nut can embed in the trepanning closely, reduces the center of gravity of nut, made nut when bolt is combined, and tightr, increased the suspension force of embedded nut.The utility model holder integrally welded with nut, make simple for structure, manufacture craft is simple.

The specific embodiment
Be the utility model structural representation below in conjunction with Fig. 2, Fig. 3 is the utility model metal nuts sectional structure schematic diagram, and Fig. 4 is described in detail the utility model for the utility model plastics fixed cover sectional structure schematic diagram for the utility model plastics fixed cover plan structure schematic diagram and Fig. 5.But be not limited to the scope of present embodiment.
Shown in Fig. 2 to 5, a kind of embedded embedded nut comprises metal nuts 1 and plastics fixed cover 2, and metal nuts 1 places plastics fixed cover 2, wherein:
Described metal nuts 1 at nut 103 top solid weldings one holder 101, and circumferentially evenly is provided with three through holes 102 in these holder 101 upper edges;
Described plastics fixed cover 2 constitutes one by trepanning 202, the cylindricality perforation 201 and the base 203 that are located at trepanning 202 peripheries, described nut 103 embeds in the trepanning 202, through hole 102 and cylindricality 201 positions of boring a hole are corresponding, holder 11 is fitted with the top of cylindricality perforation 201, bores a hole 201 fastening from holder 11 through holes 102 and the cylindricality of plastics fixed cover 2 by nail.
The internal diameter coupling of nut 103 external diameters of described metal nuts 1 and the trepanning 202 of plastics fixed cover 2.
For improving the bearing capacity of plastics fixed cover 2, the base 203 of described plastics fixed cover 2 is provided with reinforcing rib 204 with the joint portion of trepanning 202.
During use, metal nuts 1 embeds in the plastics fixed cover 2, and namely nut 103 embeds in the trepanning 202, hammers into the cylindricality perforation 201 of plastics fixed cover 2 from the through hole 102 of metal nuts 1 respectively with three steel nails, is fixed on the template.Make that when fluid concrete, this embedded nut can not be extruded movement.Because nut 103 is embedded in the trepanning 202, has reduced the center of gravity of nut 103, structure is more firm.When making nut 103 with bolted joints, tightr, increased suspension force.
