Abstract
The utility model relates to a hook bolt and belongs to the field of mechanical connection equipment. The hook bolt comprises a bolt cap and a cylindrical bolt bar, wherein an external thread is arranged on the bolt bar; a connection step is arranged at one end of the bolt bar; the bolt cap is connected with the bolt bar through the connection step; and hooks bent in the direction of the bolt bar are arranged on the two sides of the bolt cap. The hook bolt can be stably fixed by a simple bolt structure and is resistant to pressure, stretching and corrosion by a hook structure and the overall bolt structure at the same time, so that the service life of the bolt is prolonged and the manufacturing cost is saved.
Description
Technical field
The utility model relates to a kind of j-bolt, belongs to the mechanical connection apparatus field, particularly relates to a kind of linkage structure simple, the j-bolt of stable connection.
Background technique
The die mould shingle nail of steel-structure factory building adopts j-bolt to fix usually.According to the difference of metope purlin pattern, j-bolt is divided into two kinds of grooved j-bolt and angle type j-bolts, and the grooved j-bolt is used for the channel purlin position as shown in Figure 1, and angle type j-bolt is used for the angle purlin position.The grooved j-bolt is comprised of grooved screw rod, seal washer, concavo-convex packing ring and nut, and angle type j-bolt is comprised of angle type screw rod, seal washer, concavo-convex packing ring and nut.Wherein, grooved screw rod, angle type screw rod, concavo-convex packing ring and nut all adopt Q235 steel processing and fabricating to form, and all do zinc-plated processing for improving the decay resistance surface.Due to steel-structure factory building metope purlin multi-size, inevitably there is again deviation in the structure installation process, cause on-the-spot j-bolt specification, the size of using all to be not quite similar, therefore, grooved screw rod and angle type screw rod-as be all after zinc-plated finishing dealing with, bend by the concrete structure size again, this course of working of first plating palintrope can be to the zinc coat injury, and in installation, using process, j-bolt directly contacts with the steel structure purlin, zinc coat at both contacting point j-bolts is also easily damaged, thereby loses antiseptic effect.This all can cause j-bolt to be corroded, and even causes becoming rusty disconnected and makes wall and consequence that plate becomes flexible, comes off.In order to overcome the defective of the easy corrosion of common iron, a kind of j-bolt that adopts stainless steel is arranged now, although stainless corrosion resistance increases than galvanized steel, but stainless price is several times as much as the latter, and in the hydrochloric acid medium environment, the effect of stainless steel opposing hcl corrosion is unsatisfactory, still exist the fracture of screw rod easy-to-rust, working life short etc. problem.
The model utility content
The purpose of this utility model is in order to solve the existing defective of j-bolt in prior art, to provide a kind of cost low, simple in structure, easy to connect, the j-bolt that stability maintenance is good.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of j-bolt, comprise nuts and columniform bolt shank, on described bolt shank, external connection screw is set, one end of described bolt shank is provided with the connection step, connect by connecting step between described nuts and bolt shank, described nuts both sides are provided with to the gib head of bolt shank direction bending.
In above-mentioned a kind of j-bolt, it is characterized in that: the lateral cross section of described nuts is orthogonal, and an end of described bolt shank is provided with chamfering.
In above-mentioned a kind of j-bolt, it is characterized in that: described nuts be connected step by being welded to connect, described bolt shank be connected the step integral type.
In above-mentioned a kind of j-bolt, it is characterized in that: the longitudinal size of described nuts is 6-8 with being connected step transverse dimension ratio.
In above-mentioned a kind of j-bolt, it is characterized in that: the angle that the madial wall of described gib head becomes with horizontal plane is between the 25-45 degree.
In above-mentioned a kind of j-bolt, it is characterized in that: offer a groove on the top end of described nuts.
In above-mentioned a kind of j-bolt, it is characterized in that: the material of described nuts and bolt shank is low carbon steel.
In above-mentioned a kind of j-bolt, it is characterized in that: the groove cross section on described nuts is rectangle.
The beneficial effect that the utlity model has: the utility model is by its simple bolt arrangement, reached stablizing fixedly the time, simultaneously, the overall structure of its hook head structure and bolt has realized compressive resistance, stretching resistance and corrosion resistance, and then extended working life of bolt, saved manufacture cost.

Embodiment
Further understand and understanding for making structure characteristic of the present utility model and the effect reached are had, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
Referring to Fig. 1, a kind of j-bolt, comprise nuts 100 and columniform bolt shank 200, on described bolt shank 20, external connection screw 201 is set, one end of described bolt shank 200 is provided with and connects step 400, connect by connecting step 400 between described nuts 100 and bolt shank 200, described nuts 100 both sides are provided with to the gib head 300 of bolt shank 200 direction bendings.
With reference to figure 1 and Fig. 2, above-mentioned in, the lateral cross section of described nuts 100 is orthogonal, an end of described bolt shank 200 is provided with chamfering.
In above-mentioned, described nuts 100 be connected step 400 by being welded to connect, described bolt shank 200 be connected step 400 integral types.
In above-mentioned, the longitudinal size of described nuts 100 is 6-8 with being connected step 400 transverse dimension ratios.
In above-mentioned, with reference to figure 1, for easy to use, the included angle A that the madial wall of described gib head 300 becomes with horizontal plane is between the 25-45 degree.
With reference to figure 3, above-mentioned in, install for convenient, offer a groove 500 on the top end of described nuts 100.
In above-mentioned, for rigidity, intensity and the working life that guarantees bolt, the material of described nuts 100 and bolt shank 200 is low carbon steel.
In above-mentioned: for attractive in appearance and easy to process, groove 500 cross sections on described nuts 100 are rectangle.
