Description

Construction structure at connecting beam of double-sided superposed sandwich heat-insulation shear wall with window opening

Technical Field

The utility model relates to a take two-sided coincide of window opening with filling heat preservation shear force wall to be constructed of roof beam department even belongs to prefabricated two-sided coincide wallboard technical field.

Background

When the double-faced superposed system is actually constructed, if the connecting beam part above the window opening is prefabricated in a factory, the longitudinal stressed steel bars are difficult to penetrate into the beam stirrups when the steel bars are buried after the on-site hoisting is finished, so that the construction is inconvenient. Therefore, the beam position above the window opening is treated as a cast-in-place part, and then the beam position at the reserved position is embedded with the reinforcing steel bars and then formwork erecting and pouring are carried out during site construction.

Because the reinforcing steel bars of the double-sided superposed shear wall at the upper connecting beam position of the window opening are arranged more complexly, when the superposed wallboard is manufactured in a factory, only some construction reinforcing steel bars are manufactured together with the prefabricated part, and the rest cast-in-place reinforcing steel bars have the condition of difficult construction during site construction, the upper connecting beam part of the superposed wallboard window is not prefabricated in the factory under the condition, and the reserved position is delivered to site construction. After the process of arranging the reinforcing steel bars is completed on site, a process of supporting a formwork for the upper beam connecting opening of the inner leaf wall window is needed.

Preferably, the supporting member 4 is a rod member, the upper end of the supporting member is provided with a supporting leg portion, and the supporting leg portion supports the edge of the composite floor slab, so that the lap joint of the edge of the composite floor slab can be directly sealed by using joint filling mortar.

Preferably, said support 4 is provided with a plurality of vertical and parallel sets.

Preferably, the integrated disassembly-free formwork 6 is a factory prefabricated component.

Preferably, the double-sided laminated wall body is provided with a window opening.

Preferably, the support 4 is made of c-shaped steel or channel-welded steel.

Further, the supports 4 are spaced apart by an equal distance.

The beneficial effects of the utility model reside in that:

1) The template is integrally formed without detaching the template, so that the step of detaching the template is omitted, and the construction efficiency is improved;

2) The supporting of the floor by the foot of the supporting piece is also utilized while the formwork supporting of the opening is completed, so that the efficiency is improved;

3) The embedded nuts and the prefabricated templates can be manufactured in factories, and only simple assembly is needed on site, so that the construction is easy.
