Abstract
The utility model discloses a connected node structure of main couple and jack truss among pipe truss of space, the socket pipe one end of this node structure is equipped with passes through mouthful or the groove mutually, and the socket pipe other end is equipped with the notch along the circumferencial direction, and lower chord on the jack truss is gone into and through notch welded connection to socket pipe notch pot head, and arcwall face and the welded connection who leans on lower chord on the main couple mouthful is supported to the passing through mutually of socket pipe, or socket pipe's bevel end supports and depends on main couple upper chord welded ball and welded connection. Traditional primary and secondary truss installation mode defect has been overcome to this connected node structure, simple structure, and the preparation is convenient, has effectively improved construction and installation efficiency, quality and cost.
Description
Technical field
The utility model relates to building element, particularly relates to main couple and the connecting joint of jack truss in a kind of space tube truss
Dot structure.
Background technology
Truss is the support beam structure being formed by connecting by welding, riveting or bolt by rod member, and it is widely used in greatly
In all kinds of buildings such as the factory building of span, exhibition center, gymnasium and bridge.As it is shown in figure 1, space tube truss is in installation process,
First the main couple 1 installing both sides is in place, and the relative coordinate in space, main couple 1 place, physical dimension, spacing all must schools simultaneously
Just arriving in specification allowed band, then welding the jack truss 2 linked between the main couple 1 of both sides, during installation, jack truss 2 is upper
Corresponding top boom 11 that chord member 21 two ends are welded in main couple 1 by intersecting mouth or the solder sphere 13 being positioned on top boom 11, secondary
Lower boom 22 two ends of truss 2 are welded in the corresponding lower boom 12 of main couple 1 by intersecting mouth.But at main couple and jack truss
In installation process, it will face the characteristic passed through because of space tube truss Guan Guanxiang and limit, and cause linking jack truss and cannot directly pacify
Fill in place.Its main cause has jack truss chord member intersecting mouth conflict overlapping with main couple chord member, chord member intersecting mouth angular misalignment, secondary
The dislocation of chord member of truss locus, primary and secondary truss in specification allowed band be assembled and alignment error etc..As follows chord member of truss phase
Pass through mouth conflict overlapping with main couple chord member, cause the jack truss chord member cannot dropping place；Jack truss chord member intersecting mouth angle and main couple
Chord member arcwall face misplaces, intersecting mouth and arcwall face do not fit and cannot welding；Primary and secondary truss is spelled alignment error and is caused jack truss string
Bar is short or has grown and does not connects.
For the installation question of above-mentioned main couple Yu jack truss, current common construction method is the upper lower edge at jack truss
The tube head not less than 500mm is blocked to facilitate jack truss to install by specification in bar one end, carries out whole after waiting jack truss in place in high-altitude
Mouth docking, has so been significantly greatly increased workload and the difficulty of site operation, has reduced efficiency of construction.This construction method must assure that
Jack truss deflection when ground spliced is the least, but also jack truss chord member intersecting mouth to be ensured can be with main couple string
The arcwall face of bar is corresponding, owing to the pipe of jack truss own is with regard to thinner easy welding deformation, so brings the biggest to installation on ground
Control difficulty.And jack truss is in place extremely difficult in installation process, the installation of rear jack truss chord member tube head in place is installed
The biggest with high-altitude adjustment amount, as follows chord member of truss tube head installs mismatch and bias, jack truss chord member tube head away from main couple string
Bar length or short cause the weld width inconsistent, owing to when mounting process needs the tube head blocked to return dress, weld seam is necessary for
Full penetration weld, thus overhead welding workload doubles, and has welded rear pipe and easily deformed, and docking port is relatively
Many, welding quality is difficult to ensure card, and welded rear chord member may not point-blank simultaneously, and jack truss quality and outward appearance are difficult to protect
Card, installation progress is slow, and security risk increases.The most important thing is long construction period, add personnel, crane, safety measure etc.
Construction cost.

Preferably, described jack truss top boom 21, lower boom 22 at least stretch into 200mm in described socket pipe 3.
Above-mentioned node structure can use following steps to be attached:
Step one, splice jack truss in advance on ground, and adjust its welding deformation, at top boom and the lower edge of jack truss
Socket pipe is inserted at bar two ends the most in advance, is cleaned out by the foreign material in notch and socket pipe before installing socket pipe；
Jack truss is lifted between two main couples and adjusts in place by step 2, employing crane；
Socket pipe on step 3, outer shifting jack truss top boom, makes the intersecting mouth of socket pipe against main couple top boom
Arcwall face and rotary sleeve adapter make the groove of the laminating of intersecting mouth and arcwall face or socket pipe against main couple top boom solder sphere,
Weld socket pipe notch and end face and jack truss top boom, welding socket pipe intersecting mouth and main couple top boom arcwall face or socket
Pipe bevel and main couple top boom solder sphere；
