Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 and 2, the pipe truss girder and pipe truss column flange plate mounting mold comprises a frame 1, wherein the frame 1 is quadrilateral, each side of the frame 1 is located on the same plane, a flange plate 2 is arranged on each vertex of the frame 1, all the flange plates 2 are located on the same side of the frame, all the flange plates 2 are located on the same plane, the center of each flange plate 2 on the frame corresponds to the center of each pipe truss column one by one, and the frame flange plates 2 are located in the same bolt holes of the flange plates at the top of the pipe truss column to be mounted and the flange plates at the bottom of the pipe truss girder to be mounted.
The installation mold is applied to installation of a pipe truss beam and a pipe truss column flange of a quadrangular pipe truss, the frame is triangular for the triangular pipe truss, the frame is made of angle steel ∠ 90 multiplied by 5 and is mainly used for fixedly connecting the flange plates, the center points of the flange plates are welded and fixed on 4 vertex angle steel of the frame, meanwhile, the flange plates are made of steel plates with the diameter delta =8mm, the flange plates are drilled on a plane drilling machine in advance, and trepanning is completed on the pipe truss column top flange plate, the pipe truss column bottom flange plate and the frame flange plate at the same time, so that the positioning of bolt holes of the pipe truss column top flange plate, the pipe truss column bottom flange plate and the frame flange plate is completely the same.
During specific implementation, a reinforcing rod 3 is arranged between two adjacent edges of the frame 1, one end of the reinforcing rod 3 is fixedly connected with one edge, and the other end of the reinforcing rod is fixedly connected with the other edge, so that the frame 1 is reinforced, and the overall stability of the frame 1 is improved.
In this embodiment, the reinforcing rods are made of angle steel ∠ 90 × 5, the reinforcing rods are welded at four corners of the quadrilateral frame, and each reinforcing rod and two adjacent sides of the quadrilateral frame form a triangular shape, so that the reinforcing rod has the functions of reinforcing the quadrilateral frame and improving the overall stability of the frame body.
During specific implementation, the outer sides of the middle points of two adjacent edges of the frame 1 are respectively provided with a lifting lug 4, so that the frame is convenient to hoist and transport.
Here, the lug adopts the steel sheet of delta =8mm to make for alternate the shackle to accomplish the hoist and mount transportation work of installation mould in the workshop, and then accomplish the installation of the ring flange on more pipe trusses.
The method for installing the pipe truss girder and the pipe truss column flange by utilizing the pipe truss girder and pipe truss column flange installing mould in front to further finish the installation of the pipe truss column and the pipe truss column comprises the following steps;
(1) the method comprises the following steps of pre-processing a pipe truss girder and a pipe truss column for later use, and simultaneously processing a plurality of pipe truss girder bottom flange plates to be installed and pipe truss column top flange plates to be installed for later use, wherein the pipe truss girder bottom flange plates to be installed and the pipe truss column top flange plates to be installed are completely the same in positioning with bolt holes of a frame flange plate;
the pipe truss beam bottom flange to be installed, the pipe truss column top flange to be installed and the frame flange are formed by trepanning and drilling on a drilling machine, so that the pipe truss beam bottom flange to be installed and the pipe truss column top flange to be installed are completely the same in bolt hole positioning with the frame flange, and the bolt hole positioning precision is improved.
(2) Fixedly connecting a pipe truss column top flange plate to be installed on each flange plate on the frame by using bolts, enabling the pipe truss column top flange plate to be installed and the top of the pipe truss column to correspond to each other one by one, firstly performing spot welding to connect the pipe truss column top flange plate to be installed and the pipe truss column, then fixedly welding the pipe truss column top flange plate to be installed and the pipe truss column, and finally disassembling the die to complete the installation of the pipe truss column top flange plate;
thus, the angles of the top flange plate and the frame flange plate of the pipe truss column can be ensured to be completely the same.
(3) Fixedly connecting a pipe truss girder bottom flange plate to be installed on each flange plate on the framework by using bolts, enabling the pipe truss girder bottom flange plate to be installed and the bottom of the pipe truss girder support to correspond one to one, firstly performing spot welding to connect the pipe truss girder bottom flange plate to be installed and the pipe truss girder support, then fixedly welding the pipe truss girder bottom flange plate to be installed and the pipe truss girder support, and finally disassembling the die to complete the installation of the pipe truss girder bottom flange plate;
thus, the angles of the flange plate at the bottom of the pipe truss girder and the flange plate of the frame can be ensured to be completely the same.
(4) And then, installing the pipe truss column and the pipe truss beam with welded flanges on site, and respectively penetrating a plurality of bolts through holes in the flange plate at the top of the pipe truss column and the flange plate at the bottom of the pipe truss beam so as to bolt and fix the pipe truss column and the flange plate of the pipe truss beam and further complete the installation of the pipe truss column and the pipe truss beam.
Here, the bolt used may be a normal bolt or a high-strength bolt. Because the angles of the pipe truss column top flange and the pipe truss beam bottom flange in the steps (2) and (3) are the same as those of the frame flange, the angles of the pipe truss column top flange and the pipe truss beam bottom flange are also the same, and the pipe truss column top flange and the pipe truss beam bottom flange are welded and fixed with the corresponding pipe truss column and the corresponding pipe truss beam after being fixed on the frame flange, so that the welding shrinkage degree is the same, the bolting perforation rate of the pipe truss column top flange and the pipe truss beam bottom flange is not influenced, and further the perforation rate is 100%. And the pipe truss can not be reamed due to low perforation rate in the bolting process, so that the installation efficiency of the pipe truss is improved.
