Abstract
The invention particularly relates to a construction method of a large-scale cable lock head node; the method is characterized in that: longitudinally splitting the end part of an upper chord of an installed main truss, wherein the specific section is split along the arrangement surface of a gusset plate, and taking down the split arc-shaped half pipe; installing a cable gusset plate on the section of the upper chord of the main truss, resetting the end arc-shaped half pipe to the end part of the upper chord of the main truss, and installing a sealing plate of the upper chord of the main truss; an annular hoop is arranged at a joint of the arc-shaped half pipe and the upper chord of the main truss, the hoop is surrounded by two semicircular steel pipes, the hoop and the steel pipes are fillet welds, and the hoop surface and the steel pipes form a whole by plug welding; the stiffening plate between the cable node plate and the main truss is an annular stiffening plate. The node is installed by adopting the method, the cable node plate is arranged in an inclined mode, so that the tensile force can be directly transmitted to the main pipe and each branch pipe below the main pipe through the cable node plate, and the force transmission is direct and definite; the appearance is graceful, construction convenience, greatly reduced the cost, shortened the time limit for a project.
Description
Technical Field
The invention relates to the field of steel structure buildings, in particular to a construction method of a large-scale cable lock head node.
Background
In modern large building structures, the application of the zipper is more and more extensive, and among them, the lock head of the large guy cable is mostly cast, and such parts have high requirements on casting process in manufacturing, and also have the problem of difficult installation in subsequent construction and often cause the delay of the whole construction period.
Disclosure of Invention
The invention aims to overcome the defects and provides a construction method of a large-scale cable lock head node, which is scientific in structure and convenient to install.
In order to achieve the above object, the present invention is realized by:
a construction method for large-scale stay cable lock head nodes comprises
step 2, installing a cable node plate on the section of the upper chord of the main truss,
step 4, installing a sealing plate of the main truss chord member;
step 5, arranging an annular hoop at a joint of the arc-shaped half pipe and the upper chord of the main truss, wherein the hoop is surrounded by two semicircular steel pipes, the hoop and the steel pipes are fillet welds, and the hoop surface is integrally formed with the steel pipes by plug welding;
and 6, the stiffening plates between the cable node plates and the main truss are annular stiffening plates.
According to the construction method of the large-scale cable lock head node, the cable node plate and the upper chord member of the main truss are obliquely arranged, and particularly the cable node plate is inclined towards the extension direction of the cable.
The node is installed by adopting the method, the cable node plate is arranged in an inclined mode, so that the tensile force can be directly transmitted to the main pipe and each branch pipe below the main pipe through the cable node plate, and the force transmission is direct and definite; the appearance is graceful, construction convenience, greatly reduced the cost, shortened the time limit for a project.
Drawings
Fig. 1 is a schematic diagram of the present node.
Fig. 2 is a schematic diagram of the node usage state.
Detailed Description
The invention is further illustrated by the following specific examples.
As shown in figures 1 and 2, the construction method of the large-scale cable lock head node comprises the following steps
step 2, installing a cable node plate 2 on the section of the upper chord 1 of the main truss,
step 4, installing a sealing plate of the main truss chord member;
step 5, arranging an annular hoop 3 at a joint of the arc-shaped half pipe and the upper chord 1 of the main truss, wherein the hoop is surrounded by two semicircular steel pipes, the hoop and the steel pipes are fillet welds, and the hoop surface is integrally formed with the steel pipes by plug welding;
and 6, the stiffening plates 4 between the cable node plates 2 and the main truss are annular stiffening plates.
According to the construction method of the large-scale cable lock head node, the cable node plate 2 and the main truss upper chord member 1 are obliquely arranged, and specifically the cable node plate is inclined towards the cable extending direction.
The node is installed by adopting the method, the cable node plate is arranged in an inclined mode, so that the tensile force can be directly transmitted to the main pipe and each branch pipe below the main pipe through the cable node plate, and the force transmission is direct and definite; the appearance is graceful, construction convenience, greatly reduced the cost, shortened the time limit for a project.
