Prefabricated curtain wall combined with concave glass and convex metal plate and its construction method

Abstract

The invention discloses an inward-concave glass and outward-convex metal plate combined fabricated curtain wall and a construction method thereof. The inward-concave glass and outward-convex metal plate combined fabricated curtain wall comprises curtain wall keel units and metal plate modeling units; and the curtain wall keel units are fixed to a main structure, each metal plate modeling unit is connected between the two corresponding horizontally-adjacent curtain wall keel units in a hung mode, and all the metal plate modeling units are arranged in the mode of protruding towards the outdoor space from a vertical face formed by all the curtain wall keel units, wherein vertical columns of every two up-down adjacent curtain wall keel units are connected through a hinge-type insert core assembly enabling the curtain wall to achieve a double curved surface effect. The inward-concave glass and outward-convex metal plate combined fabricated curtain wall is reasonable in structural design, reliable in force bearing, the site construction amount and the construction cost are reduced greatly, the good double curved surface effect can be achieved, and the controllability of the curved surface angle is good.

Description

technical field [0001] The invention relates to a prefabricated curtain wall combined with concave glass and convex metal plate and a construction method thereof, belonging to the field of curtain walls. Background technique [0002] At present, with the continuous improvement of construction technology, architects have put forward more and more requirements for the structure and shape of the curtain wall. For example, in recent years, there has been a combination of concave glass curtain wall and convex metal plate shape to form The new type of curtain wall, this kind of curtain wall not only has a good external appearance, but also has the advantages of good sunshade effect and less material usage. However, the existing curtain wall combined with concave glass and convex metal plate has the following defects: First, it is necessary to use adapters to respectively fix the columns of the glass curtain wall and the keel of the metal plate shape to the embedded parts of the ma...

AI Technical Summary

Problems solved by technology

However, the existing curtain wall combined with concave glass and convex metal plate has the following defects: First, it is necessary to use adapters to respectively fix the columns of the glass curtain wall and the keel of the metal plate shape to the embedded parts of the main structure , the columns of the glass curtain wall and the keel of the metal plate bear the loads transmitted by the glass panels and metal plates respectively. This method consumes relatively high material costs

Second, the columns and beams of the glass curtain wall need to be installed on site one by one, which requires a lot of installation work and high labor costs

[0003] In actual construction, the columns of the glass curtain wall can also be fixed on the keel of the metal plate shape through the adapter, and only the keel of the metal plate shape is fixed to the main structure. The positive load also bears the lateral load brought by the columns, so the keel is generally made very large, which invisibly increases the cost of materials and increases the difficulty of construction, and there are still columns and beams of the glass curtain wall that need to be rooted one by one. On-site installation, heavy installation workload, and high labor costs

[0004] In addition, when the above-mentioned curtain wall achieves the hyperboloid effect, the angle between the upper and lower adjacent columns is usually adjusted in two directions by means of the steel ferrule welded in the column. The disadvantage of this is that the welding Difficult, difficult to control the angle, high construction cost
