Recyclable steel crown beam

Abstract

The invention relates to the technical field of slope protection construction, and provides a recyclable steel crown beam. The recyclable steel crown beam comprises a single crown beam structure or a double crown beam structure and a plurality of steel pipe piles, wherein the steel pipe piles are detachably mounted on the single crown beam structure or the double crown beam structure; a plurality of supporting pieces are arranged on the single crown beam structure or the double crown beam structure; and the positions of the steel pipe piles can be adjusted in the transverse direction, the longitudinal direction and the piling depth direction along the single crown beam structure or the double crown beam structure. The recyclable steel crown beam has the beneficial effects that the lengths of the supporting pieces in the double crown beam structure are fixed, the supporting pieces are mounted between two pieces of profile steel, the supporting pieces can be arranged between piles or arranged in a pile spacing manner, and the situation that the profile steel is bent when tie bolts are locked is avoided; the lengths of the supporting pieces in the single crown beam structure are not fixed, the supporting pieces with the appropriate lengths are selected according to pile position deviation and mounted between the steel pipe piles and the profile steel, and straightness deviation between the steel pipe piles is avoided; and in addition, the steel crown beam is integrally detachable, and industrialized production, field assembly and recycling of the crown beam are achieved.

Description

technical field [0001] The invention relates to the technical field of slope protection construction, in particular to a recyclable steel crown beam. Background technique [0002] Concrete crown beams or section steel crown beams are conventionally used for the connection of micro-steel pipe piles. When concrete crown beams are used, the micro-steel pipe pile ends are welded with threaded steel bars and bound to the main reinforcement of the crown beam and buried in concrete, so that each steel pipe in the enclosure structure of the micro-steel pipe piles is connected to the concrete crown beam, so that It becomes a whole. When the section steel crown beam is used, the section steel is directly welded to each steel pipe in the micro-steel pipe pile enclosure structure to form a whole and realize the connection. [0003] The existing crown beam structure is inconvenient to assemble and cannot be reused, resulting in a lot of waste of resources; in addition, the most importa...

Problems solved by technology

[0003] The existing crown beam structure is inconvenient to assemble and cannot be reused, resulting in a lot of waste of resources; in addition, the most important thing is that the existing crown beam structure is not convenient for steel pipe piles to be moved and adjusted in all directions along the crown beam, and the structure There is still much room for improvement
