Example Embodiment

[0022] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0023] A construction method for fixing cantilevered I-beam foam of the present invention, such as figure 1 As shown, the method is constructed according to the following steps;

[0024] a. First, customize the foam strip from the manufacturer according to the cantilever I-beam model; the foam strip has an I-shaped notch corresponding to the shape of the cantilever I-beam;

[0025] b. After the foam arrives, according to the thickness of the shear wall to be poured, cut the foam into short sections of foam with length=shear wall thickness B+200mm;

[0026] c. Insert one end of the cantilevered I-beam into the I-shaped notch of the foam short section and penetrate it;

[0027] d. Place and fix the cantilevered I-beam with foam short sections on the structural slab according to the requirements of the construction plan;

[0028] e. Tie the steel bars of the shear wall to...

Abstract

The invention discloses a construction method and a structure of fixing a cantilevered I beam by foam. The construction method comprises the following steps of first, inserting the cantilevered I beaminto an I-shaped notch of a foam pup joint; then arranging the cantilevered I beam sleeved with the foam pup joint on a structural plate according to a construction scheme demand; after the cantilevered I beam is arranged, mounting a reinforcing steel bar and a template of a shear wall and carrying out pouring of concrete of the shear wall; forming a construction structure of fixing the cantilevered I beam by foam after pouring of concrete of the shear wall, wherein the construction structure of fixing the cantilevered I beam by foam is reserved till an outer rack removal stage; eliminating the foam pup joint first; then pulling out the I beam after elimination; scabbing concrete holes left by eliminating the pup joint; and then plugging the holes by concrete. The construction method is simple in construction operation, a customized foam member is small in dimension, light in weight and quite convenient for field work operation, a problem of leakage of grout in a conventional processcan be reduced, and the concrete pouring quality around a connector is improved.

Description

technical field [0001] The invention relates to a construction method and structure for fixing a cantilevered I-shaped steel foam, and belongs to the technical field of building construction. Background technique [0002] In the construction of the cantilevered I-beam of the outer frame of the prior art at the place where the shear wall is encountered, the construction method of making a formwork box to retain the opening is usually adopted. And embed the I-beam anchor U-shaped ring, and wedge wood should be embedded in the anchor ring to make the I-beam and the anchor ring tightly, so that the I-beam does not shift and roll over and twist. The method of leaving the hole in the formwork box is not easy to seal the formwork at the hole, resulting in deformation at the interface and serious grout leakage, and the pre-buried anchor ring cannot be removed later, but can only be cut, resulting in high construction costs and traditional construction methods. Many, quality assuran...
