Embodiment Construction
[0041] The invention provides a formwork supporting device for deformation joints between cast-in-situ concrete double walls and a construction method thereof, which can improve the difficulty of strengthening the formwork of deformation joints, and can meet the width of deformation joints and ensure that the cross-sectional dimensions of the concrete double walls conform to the design after the formwork is removed Requirements, to avoid the occurrence of common construction quality problems such as deformation of deformation joints, wall expansion and displacement.
[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by person...

The invention provides a supporting device for deformation joint formworks between double cast-in-site concrete walls. The supporting device comprises a plurality of supporting members and a hoisting cross rod. The supporting members are vertically serially connected with one another to form a row, and are properly placed, so that the length directions and the width directions of the various supporting members are positioned in the horizontal direction, the length directions of the various supporting members are parallel to the formworks, the width directions of the various supporting members are perpendicular to the formworks, two pivot joints are formed at the ends of each supporting member along the width direction of the supporting member, and the pivot joints, which are positioned on the same side, of each two adjacent supporting members are pivotally connected with a corresponding movable connecting rod; the hoisting cross rod is connected to the pivot joint of the uppermost supporting member, so that when upward tension is applied to the hoisting cross rod, the sides, which are connected with the hoisting cross rod, of the various supporting members can be upwardly deflected around the other sides of the various supporting members, and the integral width of the supporting device for deformation joints is reduced. The supporting device has the advantages that the supporting device is arranged at the deformation joints, so that the rigidity of the insides of the deformation joints of the double walls can be improved, and construction quality accidents such as form expansion and displacement can be reduced and prevented.
Description
[0001] technical field [0002] The invention relates to the technical field of building construction, in particular to a formwork support device for deformation joints between double walls of cast-in-situ concrete and a construction method thereof. [0003] Background technique [0004] Building deformation joints, in order to prevent the impact on the use and safety of the building due to factors such as temperature changes, uneven settlement, and earthquakes, the building is disconnected at the deformation-sensitive parts in advance during design, and divided into several relatively independent units, and The reserved gaps can ensure that the building has enough deformation space, and the structural joints set up are called deformation joints. Deformation joints can be divided into three types: expansion joints, settlement joints, and shockproof joints. [0005] The width of the deformation joint between the two units is usually only 200mm. Conventional scale support is...
