Description
Technical field
The invention belongs to construction engineering technical field is and in particular to a kind of be connected spiral shell for girder steel with the one side of steel pipe column
Bolt.
Background technology
The section of steel pipe column is closed cross-section, and it is more complicated than opening section beam-to-column joint with the connection of girder steel.Need
Interim hand hole is opened up on steel pipe walls, to install internal nut.After bolt installation, close interim hand hole at the scene.In order to
Reduce the welding capacity of job site, increase the assembling degree of steel construction, one side connecting bolt can be adopted in such connection,
Realize monolateral assembly connection node.
One side connecting bolt refers to only need to just to complete the securing member of assembling in the operation of the side of connected piece, extensively
Connection for closed cross-section member in building concrete structure and steel construction.The one side connecting bolt commonly used at present is expanding screw
Bolt.But the construction of expansion bolt is complicated, needs very big moment of torsion that the big head that expands is screwed in sleeve pipe during installation, and use expanding screw
Bolt inevitably produces very big extruding to the structure of surrounding, or even damages, the safety of impact structure.Hot melt snail
Bolt is to be formed by hot melt boring to carry female hole, is directly threaded into by outer bolt and completes fastening installation, this kind connects spiral shell
The intensity of bolt depends primarily on pulling test strength from hole for the bolt, bolt hole make complicated it is desirable to high precision, and bonding strength is difficult
To ensure.Comparatively speaking, clevis bolt has many good qualities it should popularization and application.
Clevis bolt refers to exist latch in bolt column, and after clevis bolt enters bolt hole positioning, latch is from bolt column
Inside out, withstand on the inner side of bolt hole, can complete to connect by the outside tightening nut in connector.Compared to expanding screw
Bolt, clevis bolt simple structure, install and use efficient and convenient, not only can form reliable anchoring in the inner side of connector, and
And also structure will not be caused damage.Compared to hot melt boring bolt, clevis bolt is relatively low to the required precision of boring, and makes
Simpler, the anchoring strength that latch is formed in the inner side of connector is much larger than the bond stress to bolt for the tapping.
The finished product of clevis bolt is few at present, and application is also little, and this is primarily due to clevis bolt in xoncrete structure and enters
After entering bolt hole, the concrete that latch is difficult to push open surrounding completes to position.But in steel construction one side connects, work as clevis bolt
After injecting the internal cavity that bolt hole enters closed cross-section member, latch can freely produce and complete to position, and therefore should tie in steel
Structure one side promotes clevis bolt in connecting.
Content of the invention
The purpose of the present invention is for overcoming above-mentioned the deficiencies in the prior art, providing a kind of simple structure, be connected firmly, install
Using the one side connecting bolt being fast and easily used for girder steel and steel pipe column, this bolt belongs to clevis bolt, is primarily adapted for use in steel
Structure one side connects.
For achieving the above object, the present invention adopts following technical proposals：
A kind of one side connecting bolt for girder steel and steel pipe column, including bolt column, described bolt column one end has screw thread,
The bolt column other end is provided with fluting, and be rotatably connected in described fluting finite place piece, described locating part one end with hinder locating part
The latch for printed circuit being rotated matches, and is connected with ejection part, locating part between the other end of described locating part and bolt column
Before rotation, locating part is limited by latch for printed circuit and is completely embedded in fluting, eject part after unclamping latch for printed circuit and locating part is ejected
Rotate, locating part protrudes fluting, to lock steel pipe column.
Further, described slot as L-shaped, described fluting is had the vertical confined planes of the fluting being matched with locating part and opens
Groove Horizontal limiting face；The L-shaped that fluting is arranged to vertical confined planes and Horizontal limiting face, can before locating part rotates with
All play position-limiting action after rotation, preferably control locating part can be completely embedded in fluting to facilitate bolt column to penetrate connecting hole
Interior it is also possible to preferably control locating part to protrude more reliable with steel pipe column cooperation after fluting, make the locking of steel pipe column and girder steel
Connect convenient reliability.
Further, described locating part is the L-shaped with fluting mating shapes, and described locating part has and vertical limit of slotting
The vertical confined planes of rotation that plane matches, locating part also has the rotation Horizontal limiting matching with fluting Horizontal limiting face
Face；So that the shape of locating part is matched with fluting, between locating part and fluting, also there are the confined planes cooperating, can be more preferable
Realize fluting spacing to locating part.
Further, described locating part also has the fastening snap-latch surface with the cooperation of steel pipe column side；Fastening snap-latch surface is permissible
It is fitted close with steel pipe column side, by this fastening snap-latch surface, steel pipe column and girder steel are fastenedly connected by locating part.
Preferably, described locating part with to rotate the first side that is connected of Horizontal limiting face be cambered surface or inclined-plane, described the
One side is connected with fastening snap-latch surface；The first side of locating part is set to cambered surface or inclined-plane, can prevent bolt column from wearing
It is stuck when getting over bolt hole.
It is further preferred that the second side being connected with fastening snap-latch surface of described locating part is cambered surface or inclined-plane；In limit
When position part rotates, prevent locating part from producing with bolt column and interfere.
Further, described bolt column has and is provided with and the slotted eye connecting of slotting inside threaded one end, described fastener
Part is arranged in described slotted eye；Latch for printed circuit is arranged in the internal slotted eye being connected with fluting of bolt column, can be very good solid
Determine the position of latch for printed circuit, after latch for printed circuit is coordinated with locating part, twitch the rotation that latch for printed circuit can achieve locating part, convenient
Operation.
Further, described locating part and one end of latch for printed circuit cooperation are provided with groove, described groove before locating part rotation
Fasten with latch for printed circuit；Locating part is passed through groove and is coordinated with latch for printed circuit, simple structure, and latch for printed circuit inserts can in this groove
Do not rotated with convenient and reliable restriction locating part.
Described locating part is rotatably connected with bolt column by rotating shaft, described rotating shaft vertical channel setting；Both can will limit
Position part fixed position, can allow locating part rotate at this rotating shaft again.
