Description

Technical Field

[0001] The present invention belongs to the technical field of grid installation, and particularly relates to a grid installation construction device. Background Art

[0002] A grid is a building component used to build a structural support system. It is usually made of metal materials and has the characteristics of being lightweight, high-strength, and convenient for construction. It is commonly used in the construction of large-space places such as industrial factories, stadiums, and exhibition halls. The grid is made by splicing and welding straight pipe racks made of various types of metal or alloy materials, and usually has the characteristics of being light and strong, and can be assembled and disassembled as needed.

[0003] At present, during the installation and construction of the grid, lifting equipment is required to lift the pipe rack to the designated position. The lifting equipment usually includes tools and equipment such as cranes, scaffolding, lifting ropes, and lifting rigging. Before using the lifting equipment, the lifting rope needs to be tied to the pipe rack. However, during the lifting process of the pipe rack, the straight pipe rack is horizontal to the ground. If the lifting point is set improperly, or the connection points of the lifting rope and the lifting rigging are unreasonable, it will cause the center of gravity of the pipe rack to be unstable during the lifting process, resulting in large-amplitude shaking, and it is difficult to ensure the stability of the pipe fitting during the lifting process.

Detailed implementation manners

[0043] In the prior art, there is an assembled spherical tube hinged connection purlinless space frame, including upper chord bars, upper chord joints, lower chord bars, lower chord joints, web members and floor / roof panels. The upper chord bars are connected to the periphery of the upper chord joints, the floor / roof panels are fixed on the upper surfaces of the upper chord bars, the lower chord bars are connected to the lower chord joints, and the web members are connected between the upper chord joints and the lower chord joints. The upper chord joints are selected from spherical tube joints or circular tube joints.

[0044] The similarities between the spherical tube joint and the circular tube joint are that both contain short circular tubes, and sealing plates are provided at the tops of the short circular tubes. The differences are that a hollow hemisphere or a crown-cut hollow sphere is provided at the bottom of the short circular tube in the spherical tube joint, while a sealing plate is provided at the bottom of the short circular tube in the circular tube joint.

[0045] The diameter of the short circular pipe is greater than the larger value of the side length of the upper chord member, and the length is taken as the larger value of the height of the upper chord member.

[0046] The diameter of the hollow hemisphere is taken as the diameter of the short circular pipe; the diameter of the crown-cut hollow sphere is greater than the diameter of the short circular pipe, and the specific value is determined by lofting. The diameter of the open cross-section is taken as the diameter of the short circular pipe, and the height of the crown-cut hollow sphere is less than the radius of the short circular pipe.

[0047] A number of connecting plates are arranged on the circumferential side of the short circular pipe, and the upper chord member and the connecting plate of the upper chord node are connected by bolts.

[0048] The upper chord member is made of rectangular steel pipe or H-shaped steel, and the web member and the lower chord member are made of circular steel pipe or rectangular steel pipe.

[0049] The lower chord node adopts a bolt ball or a welded ball. When a bolt ball is adopted, the lower chord member and the web member are assembled and connected to the bolt ball by bolts; when a welded ball is adopted, the lower chord member and the web member are welded to the welded ball.

[0050] The floor / roof slab adopts profiled steel sheet composite floor slab, steel bar truss floor slab, or composite assembled floor slab.

[0051] When the floor span is relatively large, ribbed concrete slabs can be adopted. The floor / roof slab is connected to the lower upper chord member by stud bolts to form a whole.

[0052] The above grid has the following beneficial effects:

[0053] (1) The floor / roof slab is directly laid on the upper flange of the upper chord member, eliminating the purlin structure measures, saving steel, reducing the on-site construction procedures, shortening the construction period, and saving construction costs.

[0054] (2) The upper chord member is hinged to the spherical pipe (circular pipe) node, reducing the on-site welding workload, improving the assembly rate, and meeting the development requirements of building industrialization.

[0055] (3) The processing and manufacturing of the members and nodes are simple and convenient, and the appearance of the nodes is beautiful.

[0056] Its grid node can adopt a cyclic prefabricated steel pipe grid node to realize the assembly of the grid. The node includes steel pipe members, plugging members, high-strength bolts, sleeves and bolt balls. The head of the high-strength bolt is placed inside the steel pipe, and its screw rod sequentially passes through the plugging member and the sleeve and is threadedly connected to the bolt ball. At least one end of the steel pipe member is detachably connected to the plugging member by threads. Both ends of the steel pipe member are detachably connected to the plugging member by threads. The plugging member is a sealing plate or a cone head. When the outer diameter of the steel pipe member is greater than 75 mm, the plugging member is a cone head; when the outer diameter of the steel pipe member is less than 75 mm, the plugging member is a sealing plate. A joint is fixed at the end of the steel pipe member, and the plugging member is threadedly connected to the joint. The joint is provided with an external thread, and the plugging member is provided with an internal thread; alternatively, the joint is provided with an internal thread, and the plugging member is provided with an external thread. The plugging member is threadedly connected to the steel pipe member. The plugging member is provided with an external thread, and the end of the steel pipe member is provided with an internal thread; the plugging member is provided with an internal thread, and the end of the steel pipe member is provided with an external thread. The sleeve is an external hexagonal sleeve. Further, a long groove is provided on the side of the screw rod of the high-strength bolt, and a pin is provided on the sleeve. The pin passes through the sleeve and extends into the long groove, and a positioning groove is formed by concavely arranging the bottom of the long groove radially inward.

[0057] By adopting this node, the detachable connection between the steel pipe member and the plugging member is realized through the design of the threaded structure, which changes the traditional destructive operations such as cutting and welding of the steel pipe when replacing the high-strength bolt of the grid node. The sealing plate and the cone head are welded to the steel pipe steel parts and cannot be separated after being combined and formed. The sealing plate and the cone head are for one-time use. The replacement operation of the high-strength bolt is simple, fast and convenient, and the sealing plate and the cone head can be recycled; it solves the technical problem of the cyclic utilization of the steel pipe grid, effectively extends the service life of the steel pipe grid, and greatly improves the economic value of the steel pipe grid; at the same time, it plays a positive and profound role in reducing resource consumption, energy conservation and emission reduction, carbon neutrality and carbon peak and other environmental protection.
