Accident.
Utility model content
Therefore, to overcome above-mentioned deficiency, the utility model provide herein it is a kind of reasonable in design, it is simple in construction, it is easy to use,
The attachment means that upper steel pile casting and lower steel pile casting can be effectively linked together, are also not easy to take off in the environment of full circle swinging
Fall, and mount and dismount it is convenient, it is easy to maintenance, scale of mass production can be realized, it is readily replaceable, improve production efficiency, reduce work
Journey construction cost.
The utility model is achieved in that a kind of firm casing attachment means of full circle swinging of construction, including, pin end, mother connect
Head and bolt, wherein pin end are connected by way of welding with lower steel pile casting upper end, and the female joint is by way of welding
It is connected with upper steel pile casting lower end；
Circular diameter is more than pin end outside diameter in the female joint, and offers mother respectively in female joint and pin end
Joint screw thread hole and pin end screwed hole；The female joint screwed hole and pin end screwed hole are a plurality of, and are divided into two layers.
The bolt is divided into nut and threaded portion, and wherein threaded portion passes through female joint screwed hole and pin end screwed hole
Connection.
Preferably, the pin end screwed hole is provided with internal thread and coordinated with the threaded portion of bolt；The female joint
Screwed hole is not provided with screw thread.
Preferably, the nut portion diameter of the bolt is more than the interior circular diameter of female joint screwed hole, and in nut afterbody
Offer the groove of screwdriver swivel bolt easy to use.
The utility model has the following advantages that：
Advantage one：The utility model is designed reasonably, it is simple in construction, it is easy to use, upper steel pile casting and lower steel pile casting can be had
Linking together for effect, does not allow easy to fall off in the environment of full circle swinging yet.
Advantage two：The utility model is by reasonably designing pin end and female joint, and circular diameter is more than public affairs in female joint
Joint outside diameter, makes it more preferably install, while the internal thread coordinated with bolt is provided with pin end screwed hole, and in mother
Joint screw thread is not provided with hole, and while realizing connection, upper steel pile casting has certain interval with lower steel pile casting, can realize one
Fixed relative movement, avoid connecting tension and being not easy to turn round, be more easily damaged all the better.
Advantage three：The utility model installation and removal are convenient, easy to maintenance, can realize scale of mass production, readily replaceable, carry
High efficiency, Construction Cost is reduced, using effect is good, is suitable for large range promotion use.
