An embedded prefabricated concrete exterior wall panel and its hoisting method

Abstract

The invention relates to an embedded prefabricated concrete external wall panel and a hoisting method thereof, belonging to the technical field of building construction. The embedded prefabricated concrete external wall panel comprises an external wall panel body, wherein step-like structures are arranged on two side faces of the external wall panel body, a set of positioning holes are formed in the bottom of the external wall panel main body, and a set of hoisting rings are arranged on the inner surface of the external wall panel body. According to the external wall panel provided by the invention, the external wall panel is hoisted through the hoisting rings on the inner surface of the external wall panel, and the external wall panel is always hoisted with a gradient being 600-700 degrees formed by the prefabricated concrete external wall panel and the horizontal plane. The hoisting method comprises the following steps: firstly, fixing the lower end of the wall panel on a notch of a shaped beam of a floor; then, slowly increasing the gradient to connect the upper end of the external wall panel with the outer side face of corresponding shaped beam; firmly tightening the upper part of the external wall panel and a main body structure of a building by a pull rope through turn buckles when the external wall panel is close; loosening a hanging tool in the middle and fastening the turn buckles to lean against the wall panel on the outer side face of an upper beam after the hanging tool is pulled out of the wall; and then, fixing. The external wall panel is simple in structure, convenient and safe to operate in the construction operation, good in stability, good in visual effect of appearance and convenient to disassemble and assemble and maintain.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a prefabricated concrete outer wall panel with simple structure, good thermal insulation performance and anti-leakage effect, and convenient maintenance and a hoisting method thereof. Background technique [0002] The construction of prefabricated and assembled buildings is the mainstream development direction of green environmental protection, energy saving and emission reduction technology in the construction industry. At present, the prefabricated concrete exterior wall panel building is still in the design and construction method of synchronous and alternate construction with the main building (load-bearing) structure, that is, the main structure of the building needs to stop halfway after the construction of each floor level, and the exterior wall panels can be hoisted in place before continuing Construction, and the main structure of the building i...

Problems solved by technology

At present, the prefabricated concrete exterior wall panel building is still in the design and construction method of synchronous and alternate construction with the main building (load-bearing) structure, that is, the main structure of the building needs to stop halfway after the construction of each floor level, and the exterior wall panels can be hoisted in place before continuing Construction, and the main structure of the building is formed by pouring concrete on site. This architectural design and construction method restricts the construction speed of the building structure, and directly makes it difficult to replace the building's exterior wall panels after several years of use. The fast construction speed of prefabricated assembled buildings also loses the advantage of being easy to replace concrete exterior wall panels by block, reducing the overall economic benefits and environmental protection and energy saving indicators of the building life cycle

At present, the architectural design has not considered the building structure design required for the replacement of the exterior wall panels. The hoisting method of the exterior wall panels using the vertical panel hoisting technology is not suitable for the hoisting construction of the embedded exterior wall panels. The existing and prefabricated exterior wall panels The building structure design related to the wall panel and the hoisting method of the external wall panel need to be further innovated
