Precast outer wallboard connecting box and connecting joint

Abstract

The invention provides a precast outer wallboard connecting box and a connecting point. The precast outer wallboard connecting box is an embedded iron box of which the outer side surface is opened; the embedded iron box is embedded into a precast outer wallboard; a limiting block and an outer wallboard adjusting bolt are mounted in the embedded box; a dry hanging supporting part is transversely sleeved with the embedded iron box; the outer wallboard adjusting bolt passes through a bolt hole in the dry hanging supporting part; a sleeve connecting hole is formed in an outer sideboard of the dry hanging supporting part; an embedded sleeve is embedded into a precast overlapping beam; the front end of the embedded sleeve passes through a sleeve connecting hole in the outer sideboard of the dry hanging supporting part; a bolt fastening part is fixedly connected with a threaded hole in the embedded sleeve by pinching. According to the precast outer wallboard connecting box, the precast outer wallboard is flexibly connected with a building body, which is beneficial for earthquake proofing; an outer decorating surface of the precast outer wallboard can be manufactured in advance in a factory; the precast dry hanging outer wallboard and the building body are respectively constructed, so that the safety is ensured, the efficiency is high, the environment is protected, the energy is saved, the precision is high, and the waterproofing performance is good.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a prefabricated outer wall board connection box and a connection node in a fully assembled building. Background technique [0002] Compared with traditional cast-in-place buildings, fully-fabricated buildings are undoubtedly a major technological advancement. The prefabricated components of fully-fabricated buildings are produced in a factory and assembled on site, so that prefabricated components can be standardized, quality controllable, efficient, fast, and economical. Materials, avoid waste, no environmental pollution on the production site and construction site. Even so, innovation and progress are still needed on many technical issues, such as the wet-hanging connections between prefabricated exterior wall panels and prefabricated beams, shear walls, and prefabricated floors, which are extended from the upper section of the connecting steel bars...

Problems solved by technology

Even so, innovation and progress are still needed on many technical issues, such as the wet-hanging connections between prefabricated exterior wall panels and prefabricated beams, shear walls, and prefabricated floors, which are extended from the upper section of the connecting steel bars embedded in the prefabricated exterior wall panels. The cast-in-place layer on the upper part of the laminated floor and prefabricated laminated beams is fixedly connected with cast-in-place concrete. This kind of wet-hanging connection must be constructed simultaneously with the main body of the building. Unable to adjust, poor installation accuracy

In addition, the prefabricated exterior wall panels that have been finished in the factory are prone to contamination and damage during wet-hanging connection and pouring concrete construction, and it is difficult to protect the finished prefabricated parts
