Abstract
The invention discloses a kind of main string standard knot of double angle, including outboard angle（1）, inner side angle steel（2）, web member（3）And main chord（5）；The main chord（5）Between outside connection outboard angle（1）, inner side connection inner side angle steel（2）；The web member（3）With main chord（5）Connection.New structure of the present invention using the main string of double angle, on the premise of the carrying needs of standard knot are met, with reliable bearing capacity, anufacturability is higher, and constructs relatively simple new structure, reaches the effect for meeting use requirement.
Description
Technical field
The present invention relates to a kind of column crane mast section reinforcement structure, the main string standard knot of specifically a kind of double angle.
Background technology
In the design of derrick crane, because the change of tower body stress is required with the reasonable layout of structure, generally
Using the two methods of area of section of the size and the main string of change for changing section, to meet the carrying of tower crane.
In order to meet the carrying needs of standard knot, the area of section that changes main string is most reliable, easily method.Several normal
Meeting standard section main flat-sawn has square tube, pipe, angle steel etc., and the reinforcement method that section is square tube, pipe is conventional is cut for increasing wall thickness
Face for angle steel reinforcement method for increase wall thickness or, or between angle steel increase round steel reinforced.
On the larger derrick crane of lifting tonnage, because tower body bears larger load when working.Now, tower body is high
Degree is larger, and its Action of Vertical Loads often so that the carrying of tower body is bigger than normal, in order to reduce tower body carrying, is then used on tower body
The main string of larger cross-section, used as the ingredient-standard knot of tower body.However, strengthen the common methods of standard knot bearing capacity,
Apply in general to the tower crane of middle or small tonnage lifting capacity.In, large-tonnage tower crane, then used by structure space, section bar and limited,
Above-mentioned reinforcement method is more difficult to be suitable for.In order to effectively transmit load, it is ensured that the main string of tower crane effectively works, in design
The impact of the factors such as manufacture, arrangement should also be considered, thus the version of standard section main string needs meet space, hold simultaneously
The all many conditions for carrying, processing and install.
Content of the invention
For the problem that above-mentioned prior art is present, the present invention provides a kind of double angle main string standard knot, lifting tonnage compared with
Big derrick crane, makes the bearing capacity of the tower-body standard section of lifting tower crane more reasonable.
To achieve these goals, the technical solution used in the present invention is：A kind of main string standard knot of double angle, including outside
Angle steel, inner side angle steel, web member and main chord；Connection outboard angle in outside between the main chord, inner side connection inner side angle steel；Institute
State web member to be connected with main chord.
Of the invention further, welding outboard angle in outside between the main chord, inner side welding inner side angle steel.
Of the invention further, connected as one by bolt pair between the outboard angle, inner side angle steel and main chord.
Of the invention further, the web member is welded with main chord.
Derrick crane possesses advantages below using the structure of standard knot of the present invention：
1st, for the standard knot of truss structure, it is thus only necessary to carry out the main string of standard knot in the design phase necessary new
Design；Rigidity, purpose that intensity strengthened can reach, and increasing necessary structural element can meet detailing requiments；
2nd, according to the version of double angle standard knot so that section combination, raw tissue, local strengthening can be easily real
Existing so that manufacture processing is easily achieved；
3rd, using the easy to operate peace structural features according to the main string standard knot of double angle, it is which is being installed, is safeguarding and other
Operation provides convenient operating procedure；
4th, version is easily achieved, and processing and manufacturing is with low cost, installs, using easy to operate, defines the notable of the present invention
Advantage.
5th, the present invention considers the physical characteristics of version carrying, would be more suitable for lifting highly big, work efficiency
Big tower crane structural elements, applies on product.
Description of the drawings
Fig. 1 is welding structure schematic diagram of the present invention；
Fig. 2 is bolt fastening structure schematic diagram of the present invention；
In figure：1st, outboard angle, 2, inner side angle steel, 3, web member, 4, bolt pair, 5, main chord.
Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As illustrated in fig. 1 and 2, the main string standard knot of double angle of the present invention, including outboard angle 1, inner side angle steel 2, web member 3 and master
Chord member 5；Connection outboard angle 1 in outside between main chord 5, inner side connection inner side angle steel 2；The web member 3 is connected with main chord 5.
Wherein, web member 3 preferably adopts welding with main chord 5.
On the basis of said structure, the present invention provides a kind of embodiment of welding, as shown in figure 1, outside between main chord 5
Welding outboard angle 1, inner side welding inner side angle steel 2.
The present invention provides a kind of bolted embodiment again, as shown in Fig. 2 outboard angle 1, inner side angle steel 2 and main string
Connected as one by bolt pair 4 between bar 5.
The present invention has exclusively carried out main beam string structure form for the limited problem of the ever-present reinforcement method of traditional design
Improvement, to reach optimization structure, improve the improvement of the market adaptability of standard section main string, widened this kind of standard section main string,
Coverage in tower crane tonnage.In structure design, using the new structure of the main string of double angle, the carrying of standard knot is being met
On the premise of needs, with reliable bearing capacity, anufacturability is higher, and constructs relatively simple new structure.Reach
Meet the effect of use requirement.
Certainly, above-described embodiment is only the preferred version of the present invention, is specifically not limited thereto, on this basis can basis
It is actually needed to make having and targetedly adjusts, so as to obtains different embodiments.Due to mode in the cards more, this
In just no longer illustrate one by one.
