Steel truss multidirectional splice box type node welding formwork and node assembling method

Abstract

The invention discloses a steel truss multidirectional splice box type node welding formwork and a node assembling method. The steel truss multidirectional splice box type node welding formwork comprises a lower base and an upper constraint body and is characterized in that the lower base comprises a vertical support tube, and the wall of the upper tip of the support tube is provided with a plurality upward open slots which are arranged along the thickness direction of the wall and penetrate the wall; the upper constraint body comprises a constraint tube, a plurality of clamp plates are circumferentially fixed on the outer wall of the lower tip of the constraint tube and are vertical to the outer wall, constraint plates are circumferentially fixed on the outer wall of the upper tip of the constraint tube and are vertical to the outer wall, the lower tip of the upper constraint body is detachably connected with the upper tip of the support tube, and the clamp plates are in one-to-one correspondence to the open slots and matched with the same. The steel truss multidirectional splice box type node welding formwork has the advantages that when the formwork is used to assemble a multidirectional splice box type node, the upper constraint body is used to support and position the whole upper bending plate and the whole lower bending plate of the node; high manufacturing precision is achieved, working procedures are simplified, construction efficiency is increased, and constructers can easily master the formwork.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a steel truss multi-directional handover box-shaped joint welding formwork and a joint assembly method. Background technique [0002] With the vigorous development of steel structure buildings in my country, steel trusses are more and more widely used. Steel trusses have the advantages of large light-transmitting area and small footprint, which can meet the needs of high-end hotels and shopping centers for space, span and lighting. The steel truss is mostly composed of rods, and the rods are mostly straight rectangular steel pipes. Because the steel trusses often have a certain radian as a whole, the radian is realized through broken lines, that is, through the transition of nodes to broken lines. [0003] Steel truss nodes usually adopt multi-directional transfer box-type nodes, and multi-directional transfer box-type nodes usually have intersections an...

Problems solved by technology

However, since the rods connected to the nodes belong to the space bending and torsion structure, the section is small, and in terms of manufacturing accuracy, higher requirements are put forward for the angle, length and plane bending radian of the node joints. At present, there are still many box-type welded joints Difficulties, such as low manufacturing precision, complicated procedures, low construction efficiency, and difficult for construction personnel to master
