Embodiment Construction

[0028] Such as Figure 1-11 As shown, the bolt ball joint network frame 14 is formed by connecting the upper chord 1, the web 11 and the lower chord 12 through the bolt ball joint 3, and the bolt ball joint 3 is composed of a sleeve 15, a solid sphere 16, high-strength bolts 17 and pins 18 The axes of the upper chord, web and lower chord pass through the center of the solid sphere; the upper chord, the web and the lower chord all have cone heads 4 and sealing plates 5 at the ends, and the sealing plates reserve holes for high-strength bolts through which the high-strength bolts and screws pass For the reserved hole of the sealing plate, the high-strength bolts are screwed into the solid sphere of the reserved threaded hole by screwing the sleeve, and the nut part is blocked by the sealing plate inside the rod; the upper chord is made of square steel pipe or rectangular steel pipe, and the upper chord is Two sides are set horizontally and two sides are vertical, and the diamete...

Abstract

The invention relates to a non-purlin bolt ball node grid structure. The non-purlin bolt ball node grid structure comprises upper chord members, web members, lower chord members and bolt ball nodes. The bolt ball nodes comprise high-strength bolts, sleeves, solid spheres and pins, the upper chord members, the web members and the lower chord members pass through the solid spheres, the upper chord members adopt square steel tubes or rectangular steel tubes, two sides of the upper chord members are horizontally arranged and two sides are vertically arranged, and the diameter of the bolt ball nodes connecting the upper chord members is less than the vertical side length of the upper chord members. In the invention, all of the members can realize industrial production and are connected by the bolts on field, field welding is avoided, construction period and construction cost are shortened, purlines are not arranged at the same time, steel products are saved, and construction costs are reduced.

Description

technical field [0001] The invention relates to a space grid structure, in particular to a grid structure without purlin bolt ball nodes. Background technique [0002] The space grid structure has been greatly promoted and applied in industrial buildings and civil buildings due to its light weight and strong ability to span space. At present, the commonly used space grid structure generally adopts bolted ball joints or welded ball joints. The upper and lower chords and webs generally use round steel pipes. Through bolted ball joints, the rods are connected by ball joints to form a space grid structure system. Then The purlins are set up on the grid structure, and finally the roof panels are laid. With the application in engineering, this structural system has exposed some of its own shortcomings, mainly in the following aspects: [0003] 1. The nodes and components of this structural system are manufactured separately in the factory, and then assembled on site. Therefore, ...
