Adopt the utility model discloses make cantilever arm and the connecting plate of the joint department use of intercolumniation support and high strength bolt's range in large quantities reduce, reduced engineering cost, simplified the manufacturing process, improved site operation efficiency.
Description
Technical field
The utility model relates to steel structure connection structure, relates in particular to a kind of steel column braces linkage.
Background technology
In recent years, high-strength bolt connection has developed into and has welded one of main type of attachment of the steel work developed simultaneously, it has, and stress performance is good, endurance, anti-seismic performance are good, coupling stiffness is high, the advantages such as easy construction, be widely used in the connection of construction steel structure building site, one of Main Means becoming Steel Structure Installation.
In the Pre-tensioned Steel Structures adopting high-strength bolt to connect, the joint that H profile steel column braces adopts the mode process of the on-the-spot total cross-section splicing of component to be connected with post, beam usually, each joint web, flange portions all need to arrange gusset plate, connected by high-strength bolt again, required high-strength bolt quantity is many, gusset plate size is large, constructs loaded down with trivial details.
Utility model content
High-strength bolt quantity required when the H profile steel column braces existed to solve prior art splices is many, gusset plate size is large, the technical problem such as to construct loaded down with trivial details, and the utility model provides a kind of steel column braces linkage, optimize on-site construction processes, decrease construction workload.
The steel column braces linkage that the utility model provides forms primarily of steel column, cantilever arm, end plate, column braces and high-strength bolt, cantilever arm one end is welded with steel column and obliquely to be stretched out, the cantilever arm other end is welded with end plate, column braces two ends are all welded with end plate, end plate all has bolt hole, cantilever arm is fixedly connected with by end plate and high-strength bolt with column braces, and cantilever arm is H profile steel or is formed by steel plate splicing, and column braces is H profile steel.
Compared with prior art, the utility model is by the external part of cantilever arm and column braces two ends welded end plate, instead of web gusset plate of the prior art and frange plate gusset plate (outer edge of a wing gusset plate and interior edge of a wing gusset plate), thus the quantity of the junction plate making the joint of cantilever arm and column braces use and high-strength bolt significantly reduces, reduce construction costs, simplify processing and manufacturing process, improve site operation efficiency.Meanwhile, after adopting the utility model, require to reduce to the construction precision at connected node place, if high-strength bolt centering slightly deviation, adjust by bolt hole reaming, have between end plate during gap and also can add backing plate process, reduce the difficulty of site operation.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is the structural representation of steel column braces linkage of the present utility model, as seen from the figure, the steel column braces linkage that the utility model provides is primarily of steel column 1, cantilever arm 2, end plate 3, end plate 4, column braces 5 and high-strength bolt 6 form, cantilever arm 2 one end and steel column 1 weld together and obliquely to stretch out, cantilever arm 2 other end is welded with end plate 3, column braces 5 one end is welded with end plate 4, end plate 3 and end plate 4 all have bolt hole, cantilever arm 2 and column braces 5 are by end plate 3, end plate 4 and high-strength bolt 6 are fixedly connected with, cantilever arm 2 is for H profile steel or formed by steel plate splicing, column braces 5 is H profile steel.The distribution of high-strength bolt 6 on end plate can be determined according to actual conditions, and Fig. 2 is a kind of distribution form wherein.
The syndeton schematic diagram that Fig. 3 provides for prior art, as seen from the figure, it forms (see Fig. 5 and Fig. 6) primarily of steel column 1, cantilever arm 2, column braces 5, high-strength bolt 6, web gusset plate 7, outer edge of a wing gusset plate 8 and interior edge of a wing gusset plate 9.Can be found out by Fig. 4 ~ 6, adopt web gusset plate to be connected with edge of a wing gusset plate, the quantity of junction plate and high-strength bolt is far away more than the quantity of the utility model end plate and high-strength bolt.
For the utility model, the size of end plate is determined according to column braces cross-sectional sizes, and to the H profile steel column braces in conventional HW100 × 100 ~ cross section, HW300 × 300, end plate thickness is selected between 20 ~ 30mm.The quantity of high-strength bolt and model are determined according to force analysis and detailing requiments, and quantity is between 2 ~ 12, and model is selected between M16 ~ M24.
For the column braces in cross section, HW150 × 150, in the prior art, based on the principle waiting strong ties, web needs 4 M16 high-strength bolts, by 2 pieces of 80mm wide × gusset plate that 285mm length × 8mm is thick connects, the upper and lower edge of a wing respectively needs 8 M16 high-strength bolts, by 150mm outside 2 pieces of edges of a wing wide × outer edge of a wing gusset plate that 285mm length × 10mm is thick, and inside the edge of a wing 4 pieces of 60mm wide × interior edge of a wing gusset plate that 285mm length × 10mm is thick connects, a joint needs 20 M16 high-strength bolts altogether, 8 pieces of thick 0.2m altogether of 8mm
2junction plate, construction workload is large, and cost is high.
After adopting the utility model joint form, only need 2 pieces of 180mm wide × the high-strength bolt connection of the thick end plate of 310mm length × 24mm and 6 M20, a joint only needs 6 M20 high-strength bolts, 2 pieces of thick 0.11m of 24mm
2gusset plate, greatly reduce construction workload, effectively can improve efficiency of construction.
Although the foregoing describe detailed description of the invention of the present utility model, but those skilled in the art is to be understood that, these only illustrate, under the prerequisite not deviating from principle of the present utility model and essence, column braces is connected with beam, the steel column braces of column braces right-angled intersection intermediate node and other section form or size is also suitable for.
