Abstract
The invention discloses arrester shearing resistance connection structures, sudden strain of a muscle bar is connect including two faces, the right opposite for connecing sudden strain of a muscle bar of two faces is arc, it is additionally provided with link block connecing the outer surface for dodging the end point side of right opposite of bar, two piece-root grafting dodges bar and passes through the spring connection between link block.By by entirety connect dodge that bar is divided into two faces connect sudden strain of a muscle bar, it is attached in junction using spring, in the shearing by beam wind etc, spring can be bent, and guarantee connects sudden strain of a muscle bar and is unlikely to fracture, when calm, it connects sudden strain of a muscle bar to restore under the action of the spring, guarantee connects sudden strain of a muscle bar can vertically upward, simultaneously, right opposite is that cambered surface is conducive to point discharge, i.e. two piece-root graftings, which are dodged between bar, does not need physical connection.The invention has the advantages that shearing resistance is had excellent performance, protection connects sudden strain of a muscle bar and is not fractureed by shearing, highly-safe；Directly the existing sudden strain of a muscle bar that connects can be reequiped, improving cost is low.
Description
Technical field
The present invention relates to a kind of arresters, and in particular to arrester shearing resistance connection structure.
Background technique
Lightning protection device is made of arrester, downlead and earthing or grounding means.Arrester is located at the top of lightning protection device, effect
It is to be higher by the protruding parts of protected object using it thunder and lightning is guided into itself, accepts direct lightning strike electric discharge.Arrester is by following each shape
One of formula or any combination form: independent lightning rod；Lightning rod, lighting proof strip or the lightning conduction being installed directly on building；Room
Permanent metal object and metal Roof on top；Reinforcing bar in concrete component.In addition to using reinforcing bar in concrete component, arrester
Answer zinc-plated, weld should apply anti-decaying paint.In the stronger place of corrosivity, it should also suitably increase its section or other anti-corrosions is taken to arrange
It applies.
China has also issued GB50057 for building lightning protection, and according to the requirement of GB50057, connecing sudden strain of a muscle bar should right angle setting
In building, since existing connect dodges bar and mostly use rigid material greatly, connecing vertically upward dodges bar can when being influenced by beam wind
It can fracture, make the lightning protection properties decline of building.
Summary of the invention
The technical problem to be solved by the present invention is to the existing sudden strain of a muscle bars that connects to mostly use rigid material greatly, therefore vertically upward
Connecing sudden strain of a muscle bar may fracture when being influenced by beam wind, decline the lightning protection properties of building, and it is an object of the present invention to provide arrester shearing resistance
Connection structure solves the problems, such as to connect and dodges bar by shearing frangibility.
The present invention is achieved through the following technical solutions:
Arrester shearing resistance connection structure connects sudden strain of a muscle bar including two faces, and connecing for two faces is dodging bar just
Opposite is arc, is additionally provided with link block connecing the outer surface for dodging the end point side of right opposite of bar, two piece-root grafting dodges bar
It is connected by the spring between link block.By by entirety connect dodge that bar is divided into two faces connect sudden strain of a muscle bar, connecting
Place is attached using spring, and in the shearing by beam wind etc, spring can be bent, and guarantee connects sudden strain of a muscle bar and is unlikely to fracture,
When calm, connect dodge bar restore under the action of the spring, guarantee connect dodge bar can vertically upward, meanwhile, right opposite is conducive to for cambered surface
Point discharge, i.e. two piece-root graftings, which are dodged between bar, does not need physical connection.
It includes at least three link blocks that every piece-root grafting, which is dodged on bar, and the end point side of link block on the right side is uniformly divided
Cloth.At least three link block, which is uniformly distributed, constitutes relatively stable support construction, while can satisfy to the curved need of all directions
It asks.
The connection number of blocks that two piece-root grafting is dodged on bar is identical, and face, the spring are connected to facing each other one by one for position
Two link blocks between.Using the above structure, the connection for dodging two piece-root graftings between bar is more stable.
At least three spine is additionally provided on the arc right opposite of the two piece-root graftings sudden strain of a muscle bar.According to point discharge principle, electric current
It can be dodged between bar and be conducted without physical connection in two piece-root graftings by spine, and can guarantee connecing sudden strain of a muscle using multiple spines
Still there is one group of spine to lean on when rod bending relatively close.
Compared with prior art, the present invention having the following advantages and benefits:
1, arrester of the present invention shearing resistance connection structure, shearing resistance are had excellent performance, and protection connects sudden strain of a muscle bar and do not fractureed by shearing,
It is highly-safe；
2, arrester of the present invention shearing resistance connection structure can directly reequip the existing sudden strain of a muscle bar that connects, be modified to
This is low.
Detailed description of the invention
Attached drawing described herein is used to provide to further understand the embodiment of the present invention, constitutes one of the application
Point, do not constitute the restriction to the embodiment of the present invention.In the accompanying drawings:
Fig. 1 is schematic structural view of the invention.
Label and corresponding parts title in attached drawing:
1- connects sudden strain of a muscle bar, 101- right opposite, 2- link block, 3- spine, 4- spring.
Specific embodiment
