Abstract

The invention discloses a high-strength concrete facade cross node constrained by a steel mould containing a steel reinforcement framework, relating to a reinforced concrete facade cross node, and solving the problems that the traditional reinforced concrete facade cross node has low bearing force, can not satisfy the requirements of a strong node, can not guarantee construction quality, and has high construction price. A horizontal steel reinforcement rack and two inclined steel reinforcement racks are respectively bound and shaped; four vertical steel reinforcements and a plurality of stirrups bind the horizontal steel reinforcement rack and the two inclined steel reinforcement racks into the steel reinforcement framework; the steel reinforcement framework is arranged in the internal hollow cavity of each steel plate mould; a butt joint along two single-piece steel plate moulds is in full weld; high-strength concrete is poured in the internal hollow cavity of the steel plate mould; and after conserved, the steel plate moulds, the steel reinforcement framework and the high-strength concrete form a whole to form the high-strength concrete facade cross node constrained by the steel mould containing the steel reinforcement framework. The high-strength concrete facade cross node is used for a batter post cross node with a high-rise tube in a tube structure of reinforced concrete.

Description

technical field [0001] The invention relates to a reinforced concrete facade intersection joint in the field of civil engineering. Background technique [0002] The reinforced concrete façade intersection joint formed by the intersection of oblique cross columns is a plane force unit. The oblique compression and lateral expansion deformation of this type of joint due to external loads are mainly borne by the core concrete in the joint area and its surrounding stirrups. , resulting in greater brittleness of the joints, low bearing capacity, and difficulty in meeting the requirements of strong joints; at the same time, during the construction of such joints, the joints are shaped according to the construction method of binding the steel skeleton, supporting the formwork, pouring concrete, and removing the formwork after curing. The reinforced concrete façade intersection joint obtained by the existing construction method is cumbersome in the construction process, it is difficu...
