Background

With the continuous development of the construction industry, metal sandwich panels are gradually applied to various buildings. Most of metal sandwich plates adopt two layers of high-quality color coating steel plates (or stainless steel and aluminum magnesium manganese) as panels, after roll forming, the core materials and the metal panels are strongly bonded through high-strength binders, and the building plates with good leveling, attractive appearance, fire resistance, heat preservation and sound insulation performance are compounded. The composite material has the advantages of large rigidity and high bearing capacity, can effectively reduce the manufacturing cost of supporting systems such as wall beams and the like, combines factory prefabrication and field assembly, and can be widely applied to assembly type buildings.

At present, when the sandwich panel commonly used in engineering is used, the sandwich panel is in a two-way plate stress state under the action of wind suction force of a wall surface, and the sandwich panel has bending in span and width directions. When wind power is high, stress at the rabbet between the sandwich boards is increased, stress concentration is easy to occur at the bonding part of the core material and the metal panel at the rabbet, and when the stress exceeds the bonding strength between the core material and the panel, the rabbet is torn to cause damage.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without any creative efforts shall fall within the protection scope of the embodiments of the present invention.

The inventor in practice finds that in the prior art, the sandwich panel wall enclosure system is easily damaged by wind when in use, especially in high wind pressure areas or high wind pressure areas of buildings.

The reason for this is that the current domestic and foreign literature relating to the bearing capacity of the sandwich plate enclosure system mainly includes "metallic surface heat insulation sandwich plate for building" GB/T23932- "2009," metallic surface heat insulation sandwich plate technical regulation "CECS 411-2015," Self-supporting double skin metallic insulation panels-Factory map products-Specifications "BS EN 14509: 2013. The bearing capacity and mechanical property research of the sandwich plate in the documents is based on the test of a single plate under the action of different types of loads, and the sandwich plate enclosure system is not taken as a whole research, so that the actual stress and failure mode deviation of the sandwich plate enclosure system is extremely large, the sandwich plate system designed according to the standards has great potential safety hazard, and the potential safety hazard is also the reason that the sandwich plate wall enclosure system is damaged by wind in recent years.

At present, the width of a sandwich board commonly used in engineering is generally 500-1000 mm, male and female ribs are arranged on two sides of the sandwich board, the male ribs are fixed on a supporting purline by self-tapping screws during installation, and then the female ribs of the next sandwich board are buckled and inserted on the male ribs of the previous sandwich board, so that a hidden nail type tongue-and-groove structure connection is formed. The spacing between the supporting purlins for fixing the sandwich panel is generally about 3 m.

The ratio of the span of the sandwich board to the width of the sandwich board is generally 2-3 through the connecting structure, the sandwich board is in a two-way board stress state under the action of the wind suction force of the wall surface, and the sandwich board is bent in the span and width directions. The bending along the board width direction leads the close tongue-and-groove connection of the male ribs and the female ribs of the adjacent sandwich boards to be gradually opened, along with the opening of the tongue-and-groove, the contact area between the male ribs and the female ribs is smaller, the compressive stress on the contact surface is increased, the stress concentration occurs at the bonding part of the core material and the metal panel at the tongue-and-groove part of the female ribs, and when the stress exceeds the bonding strength between the core material and the panel, the female ribs at the tongue-and-groove part are torn to cause damage. The stress and damage mode is proved in a wind uncovering resistance test of a plurality of groups of sandwich plate systems.

In view of the above problems, embodiments of the present invention provide a wind uncovering resistant node structure, a wall space enclosure system and a construction method, which can effectively avoid wind uncovering damage of a wallboard due to tongue-and-groove relaxation and stress concentration, and greatly improve wind uncovering resistance of the wallboard.

When the first wall board 30 and the second wall board 40 bear wind load, the bending deformation of the wall boards along the extending direction of the vertical purlin 20 can be eliminated through the vertical purlin 20, so that the tongue-and-groove loosening between the sandwich boards at the joint of the vertical purlins 20 is avoided. The first fastening piece 50 passes through the second connecting part 41 to be connected with the vertical purlin 20, and the same wind uncovering resistant effect is achieved.
