Embodiment

[0038] refer to figure 1, which is a convenient disassembly and assembly disclosed by the present invention, butt metal joint, including a metal sheath 71 and a fastening piece. Among them, the metal sheath 71 is composed of a first metal plate bend 1 and four second metal plate bends 2, and the fastening member includes a buckle plate 3, a wing plate 4, a driving lever 5 and a fastening disc 6 and other structures. The fastening member fastens the first metal plate bend 1 and the second metal plate bend 2 at the junction of the two secondary flutes 9, and uses friction to butt the secondary flutes 9.

[0039] refer to figure 1 and figure 2 , the first metal plate bend 1 is arranged along the length direction of the secondary flute 9, the cross section of the first metal plate bend 1 is U-shaped, and the first metal plate bend 1 is buckled at the junction of the two secondary flutes 9 from top to bottom , and the two ends of the first metal plate bend 1 are respectively la...

Abstract

The invention relates to the technical field of building construction, and particularly relates to a secondary ridge butt joint metal joint convenient to disassemble and assemble. The secondary ridgebutt joint metal joint comprises a metal sheath and a fastening piece, wherein the metal sheath comprises a first metal plate bend and a second metal plate bend; the fastening piece comprises reversebuckling plates and wing plate; the reverse buckling plates are arranged in the length direction of a secondary ridge; the cross sections of the reverse buckling plates are U-shaped; openings of the reverse buckling plates face the secondary ridge; one sides, far away from the second metal plate bend, of the reverse buckling plates are connected with the side edge of the first metal plate bend; the inner walls of the other sides of the reverse buckling plates are obliquely arranged relative to the length direction of the reverse buckling plates; the inclination angles of the inner walls of thereverse buckling plates relative to the length direction of the reverse buckling plates are smaller than the friction angles between the reverse buckling plates and the wing plates; the wing plates are arranged in the length direction of the secondary ridge; the wing plates are connected with the side edge of the second metal plate bend; and the wing plates are slidably clamped with the reverse buckling plates in the length direction of the secondary ridge. The secondary ridge butt joint metal joint has the effects of being easy to operate and convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a secondary corrugated butt joint metal joint which is convenient for disassembly and assembly. Background technique [0002] During the building construction process, on-site pouring of reinforced concrete components (such as columns, beams, slabs, etc.) needs to be completed with the help of molds. The mold is generally composed of multi-layer wood plywood, secondary flute, main flute and pull bolts. Among them, multi-layer wood plywood is also called formwork, and the secondary flute and main flute are mostly made of wood square or metal square. [0003] In order to facilitate handling and assembly, the length of the secondary flute is generally 2 meters, 4 meters and 6 meters. When the structural size is greater than the length of the secondary flute, it is necessary to extend the secondary flute. [0004] The Chinese patent with the notification number CN1051...
