Detailed Description
The following describes specific embodiments of the present utility model in detail with reference to the drawings.
Referring to fig. 1 and 2, the utility model provides a steel structure truss girder upper chord member connection system, which comprises an upper chord member main part 2, wherein a plurality of upper chord support joints 1 are arranged on the upper chord member main part 2, two web members 3 are fixedly connected to the bottom ends of the upper chord support joints 1, and the two web members 3 at the bottom ends of the upper chord support joints 1 are fixedly installed through a connection system component 4; the connecting system assembly 4 comprises a steel groove 41, two ends of the steel groove 41 are connected with splice plates 42 through bolts, and the two splice plates 42 are fixedly installed with two web members 3 at the bottom end of the upper chord support joint 1 through bolts respectively.
Referring to fig. 2, the reinforcing plates 421 are fixedly installed at one side of the two splice plates 42 by means of the bolts, preventing the splice plates 42 from being deformed and broken.
Referring to fig. 2, two splice plates 42 are movably connected at both ends of the steel groove 41 by bolts, so that the splice plates 42 can be rotated, and the inclination angle of the web member 3 can be matched when the tie assembly 4 is connected with the web member 3.
The working principle of the utility model is as follows: deformation of the upper chord main part 2 in the installation process is mainly concentrated before the structure is formed into a whole, the condition that the upper chord support joint 1 is easy to expand or retract in the process of bearing dead weight is presented, and the two web members 3 are provided with the connecting system component 4 to form a pulling force, so that the condition that the upper chord support joint 1 expands and retracts can be effectively avoided, the deformation of the upper chord main part 2 in the installation process is avoided, the total splicing stage can be manufactured in a factory, and a movable connecting system is additionally arranged after the upper chord main part 2 is accurately positioned; and (5) temporarily removing after the assembly is finished, and installing after the assembly is delivered to the site.
The foregoing has shown and described the basic principles, principal features and advantages of the utility model. The present utility model is not limited to the above-described embodiments, and the above-described embodiments and descriptions merely illustrate the principles of the utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model, which is defined by the appended claims. The scope of the utility model is defined by the appended claims and equivalents thereof.
