Description
Technical Field
The utility model relates to a building shock attenuation technical field specifically is a structure for preventing that pin shaft connecting member distal end face outer displacement is enlargied.
Background
The pin shaft connection has larger bearing capacity, but because the outer lug plate and the inner lug plate have gaps between the pin shaft and the hole, the plane external rigidity of the pin shaft connection position is lower. In the structural application of building engineering, once the external uncertain load is borne, such as under the action of temperature, earthquake or impact, the external displacement is easy to occur, so that the central lines of connecting rod pieces at two ends of a pin shaft are not on the same straight line, secondary external displacement is caused, and even a connecting node is deformed.
In order to solve the problems, the invention provides a structure for preventing the external displacement of the far end surface of a pin shaft connecting rod piece from being amplified.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the technical problem that above-mentioned prior art exists, provide a structure that is used for preventing the outer displacement of pin shaft connecting rod spare distal end face from enlargiing.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a structure for preventing pin hub connection member distal end face outer displacement is enlargied, includes round pin axle, interior otic placode and outer otic placode are through round pin hub connection, offer the round pin shaft hole that is used for installing the round pin axle on interior otic placode and the outer otic placode, still set up threaded hole on the outer otic placode, threaded hole is equipped with the bolt, the bolt passes outer otic placode and supports interior otic placode, makes outer otic placode and interior otic placode remain the parallel throughout.
Preferably, the tail part of the bolt contacted with the inner ear plate is an arc surface, so that the contact area of the bolt and the inner ear plate is reduced, and the friction force is reduced.
Preferably, the bolt is perpendicularly connected with the outer ear plate and the inner ear plate.
Preferably, each outer ear plate is provided with two threaded holes and two bolts, and the two threaded holes are symmetrical according to the pin shaft hole.
Preferably, the two bolt holes are positioned on two sides of the pin shaft hole, and lines connecting center points of the three holes of the threaded hole and the pin shaft hole corresponding to the upper outer lug plate and the lower outer lug plate coincide with the axis of the inner lug plate side connecting rod piece.
Preferably, the length of the screw rod of the bolt is the sum of the gap between the inner ear plate and the outer ear plate and the thickness of the outer ear plate, so that the inner side of the nut of the bolt is tightly attached to the outer side of the outer ear plate.
The utility model discloses technical effect lies in: the utility model discloses an twist the bolt at outer otic placode, the otic placode in the bolt afterbody supports, makes inside and outside otic placode keep parallel, prevents effectively that secondary off-plate displacement or connected node from warping, ensures connection structure's permanent reliable.
