Problems solved by technology

[0003] At present, the trusses used for walls such as building assembly slats, floor decks, roof panels, and cantilever panels are all processed by bending and forming, then bound, and then welded. The process is complicated.
At present, the more common structural composition is the upper and lower two-layer steel mesh structure, and the Z-shaped steel bar is used as the support in the middle to form the overall structure by binding. Control procedures are cumbersome
Second, production workers have high labor intensity and low production efficiency
Third, the overall stability of the reinforced grid structure is poor and easy to deform
Fourth, there are many varieties and specifications of electromechanical equipment investment, and thus large capital investment; the corresponding production plant space and site occupation is large, and the equipment and personal safety protection factor is small
Fifth, there are many leftover materials and waste, the utilization rate is low, and the production cost is high

Embodiment 1

[0033] See figure 1 , Select cold-rolled 16Mn steel plate to make expanded metal mesh, plate thickness: h=3mm, square mesh: k=50×50mm. Roll the truss with a large cross-section by using a rolling mill with large rolls. The size of the truss is: length L×width B×height H=2960mm×560mm×60mm.

Embodiment 2

[0035] See figure 2 , choose cold-rolled carbon steel plate to make expanded mesh, plate thickness: h=5mm, square mesh: k=100×100mm. M-shaped cross-section trusses are rolled by rolling mills with M-shaped rolls, and the dimensions of the trusses are: length L×width B×height H=3560mm×1160mm×80mm.

Embodiment 3

[0037] See figure 1 , choose hot-rolled Q235 round bar, round bar diameter Straightening, sizing, and automatic welding to form a mesh with a mesh size of 60×60mm, and then use a rolling mill to roll into a truss with a large cross-section; truss size: length L×width B×height H=2960mm×560mm×60mm.

Abstract

The invention relates to a metal truss for a wall assembly board. The cross section of the metal truss is an M or n shaped structure; and the metal truss is formed by adopting a rolling mill to carryout cold rolling on a steel net. The metal truss is formed in the following way: at first, round steel is welded into a net, and then the net is rolled by the rolling mill to form the structure, and the cross section of the structure is M or n shaped. The metal truss has the following advantages: the structure is reasonable, the rolling equipment and anticorrosion spraying equipment are compact incooperation, the operation is simple, production is carried out through rolling of the rolling mill, automatic control is applicable, and the personnel allocation of the existing production line is reduced.

Description

technical field [0001] The invention relates to the field of wall construction, in particular to a metal truss used for a wall assembly plate. Background technique [0002] The invention relates to a production technology for integral rolling of metal trusses used for wall assembly panels, especially suitable for the preparation of reinforcement requirements for building wall assembly strips, floor decks, roof panels, cantilever panels, etc.; In factory semi-automatic or fully automatic production to meet the requirements of architectural design, building products and building construction. [0003] At present, the trusses used for walls such as building assembly slats, floor decks, roof panels, and cantilever panels are all processed by bending and forming, then bound, and then welded. The process is complicated. At present, the more common structural composition is the upper and lower two-layer steel mesh structure, and the Z-shaped steel bar is used as the support in the...
