The utility model aims to solve the technical problem that a segmentation combination formula truss is provided, can solve present super large tower crane tower body standard festival and be limited by this technological problem of transportation size restriction.
In order to solve the technical problem, the utility model provides a piece-wise combined truss, which is formed by welding and connecting four same standard sections, wherein each standard section comprises a main chord member, a transverse web member, an inclined web member and a flange; the main chord is in the vertical direction; the transverse web members are in the horizontal direction and are perpendicular to the main chord members, and every 2 transverse web members are positioned in the same horizontal position and are perpendicular to each other to form a group of transverse web members; one end of the inclined web member is fixed at the tail end of the transverse web member, and the other end of the inclined web member is fixed on the main chord member; the flange is fixed at the tail end of the transverse web member; and the standard sections are connected through flanges to form the split combined type truss.
Preferably, the cross web members are provided with 2 groups in the same direction, respectively at the upper end and the middle position of the main chord member.
Preferably, the cross web members are provided with 2 groups in the same direction, and the 2 groups are respectively positioned at the upper end and the lower end of the main chord member.
Preferably, the ends of the group of transverse web members at the upper end of the main chord member are also connected with reinforcing rods.
Preferably, the standard joints are connected through flange bolts and welded to form the combined truss.
The beneficial effects of the utility model are that:
1. the utility model discloses a burst combination formula truss is by four the same standard festival mutual welded connection, can divide into four transports one by one, and on-the-spot built-up welding has greatly reduced the transportation degree of difficulty and cost of transportation, the manufacturing of being more convenient for during the use.
2. The utility model discloses a M type structure is constituteed to main chord member, horizontal web member, oblique web member to connected mode through flange bolt has guaranteed super large tower crane's bearing capacity.

Detailed Description
Example 1
As shown in fig. 1-2, a split combined truss is formed by welding four identical standard joints, wherein the standard joints comprise a main chord member 1, a transverse web member 2, an inclined web member 3 and a flange 4; the main chord 1 is in the vertical direction; the transverse web members 2 are in the horizontal direction and are perpendicular to the main chord members 1, and each 2 transverse web members 2 are positioned in the same horizontal position and are perpendicular to each other to form a group of transverse web members 2; one end of the inclined web member 3 is fixed at the tail end of the transverse web member 2, and the other end is fixed on the main chord member 1; the flange 3 is fixed at the tail end of the transverse web member 2; the standard sections are connected through the flanges 4 through bolts and are welded to form the combined truss. The transverse web members 2 are provided with 2 groups in the same direction and are respectively positioned at the upper end and the middle position of the main chord member 1. The tail ends of a group of transverse web members 1 positioned at the upper end of the main chord member 1 are also connected with a reinforcing rod 5.
Example 2
As shown in fig. 3-4, a split combined truss is formed by welding four identical standard joints, wherein the standard joints comprise a main chord member 1, a transverse web member 2, an inclined web member 3 and a flange 4; the main chord 1 is in the vertical direction; the transverse web members 2 are in the horizontal direction and are perpendicular to the main chord members 1, and each 2 transverse web members 2 are positioned in the same horizontal position and are perpendicular to each other to form a group of transverse web members 2; one end of the inclined web member 3 is fixed at the tail end of the transverse web member 2, and the other end is fixed on the main chord member 1; the flange 3 is fixed at the tail end of the transverse web member 2; the standard sections are connected through the flanges 4 through bolts and are welded to form the combined truss. The transverse web members 2 are provided with 2 groups in the same direction and are respectively positioned at the upper end and the lower end of the main chord member 1. The tail ends of a group of transverse web members 1 positioned at the upper end of the main chord member 1 are also connected with a reinforcing rod 5.
Can see from above-mentioned embodiment, the utility model discloses a burst combination formula truss is by four the same standard festival mutual welded connection, can divide into four transports once, and on-the-spot built-up welding during the use, greatly reduced the transportation degree of difficulty and cost of transportation, the manufacturing of being more convenient for. The utility model discloses a M type structure is constituteed to main chord member 1, horizontal web member 2, oblique web member 3 to the connected mode through 4 bolts of flange has guaranteed super large tower crane's bearing capacity.
The above description is illustrative and not restrictive. Many modifications and variations of the present invention will be apparent to those skilled in the art in light of the above teachings, which will fall within the spirit and scope of the invention.
