Embodiment 1

[0039] Embodiment one sees Figure 2-4 As shown, the general lengths of double-layer coupling beams are: 1800mm, 2400mm, 3200mm, 3300mm, etc. The length of the opening of the double-layer coupling beam that needs formwork support is less than 3m. This double-layer coupling beam opening formwork system includes an opening formwork and a formwork support. The opening formwork includes a frame body 1 and a frame back flute 2. The frame The body support is arranged in the opening of the double-layer coupling beam and adapts to the size of the opening of the double-layer coupling beam, at least including the upper side plate 1.1, the lower side plate 1.2, the left side plate 1.3 and the right side plate 1.4, and the opening formwork also includes At least one lower ash vibrating cylinder 3 vertically connected to the upper side plate and the lower side plate is provided inside the frame body.

[0040] There is an upper opening 1a on the upper side plate 1.1, and a corresponding lo...

Embodiment 2

[0044] Embodiment two see Figure 6-7As shown, the difference from Example 1 is that the length of the double-layer connecting beam hole that needs formwork is greater than 3m. In order to ensure the appearance and structural quality after the concrete pouring and formwork removal, the lower ash vibrating cylinder 3 is at least set Two, three are provided in this embodiment, the spacing is 0.75m, and they are arranged in a straight line along the length direction of the double-layer connecting beam.

[0045] The frame body of the present invention can also form a box body after adding a front side plate and a rear side plate.

[0046] The construction steps of the above two double-layer coupling beam construction methods using the double-layer coupling beam opening formwork system are as follows:

[0047] Step 1, binding the steel bars 7 of the double-layer connecting beam and the column bars 8 of the structural columns on both sides of the double-layer connecting beam.

Abstract

The invention provides a double-layer coupling beam hole opening formwork system and a construction method of the double-layer coupling beam hole opening formwork system applied to a double-layer coupling beam. The double-layer coupling beam hole opening formwork system comprises a hole opening formwork and a formwork support; the hole opening formwork comprises a frame body and a frame body back edge; the frame body is arranged in a double-layer coupling beam hole opening and is matched with the double-layer coupling beam hole opening in size; the frame body at least comprises an upper side plate, a lower side plate, a left side plate and a right side plate; and the hole opening formwork further comprises at least one lower ash vibrating drum which connects the upper side plate with the lower side plate in a vertical through mode and is arranged in the frame body. The construction method comprises the steps of reinforcing steel bar bundling, hole opening formwork mounting, concrete pouring, drum column removing, curing and the like. The double-layer coupling beam hole opening formwork system and the construction method of the double-layer coupling beam hole opening formwork system applied to the double-layer coupling beam greatly reduce the quality defects of concrete, avoid forming of air holes in beam side forms, reduce construction procedures of hole forming and plugging, and shorten construction periods; and meanwhile according to the construction method, the flatness of the reinforcing steel bar protective layer of a concrete component around the hole opening and the flatness of a structure concrete face are controlled, and the poured concrete is good in appearance and quality.

Description

technical field [0001] The invention relates to a formwork system and a construction method thereof, in particular to a formwork system for an opening between double-layer connecting beams of a reinforced concrete structure and a construction method applied to double-layer connecting beams. Background technique [0002] There are generally double-layer connecting beams above the door and window openings on each floor of the core tube of the main building. In the traditional formwork method of double-layer connecting beams, extruded polystyrene boards are fixed between the double-layer connecting beams to be poured as a template, and the side forms of the lower connecting beams are provided with air holes, and the fluidity of the concrete is used when pouring concrete. From the column formwork on both sides of the double-layer connecting beam, it flows into the formwork of the lower connecting beam to fill it up, and at the same time vibrates the side formwork of the double-l...
