Abstract
The invention discloses a fireproof nail for a building outer wall heat insulation system, which comprises a spring, a connecting piece and a bolt, wherein the connecting piece is connected with the spring and the bolt, the root of the spring is spirally wound outside the connecting piece, one end of the bolt is screwed into the connecting piece, the other end of the bolt is used for anchoring on an outer wall, one end of the fireproof nail provided with the spring and the connecting piece is arranged in a heat insulation decoration integrated plate, and the head of the spring is positioned in an inorganic decoration layer on the surface.
Description
Technical Field
The invention relates to a fireproof component of an external wall heat insulation system, in particular to a fireproof nail of a heat insulation and decoration integrated plate for an external wall of a building.
Background
The heat preservation decoration integrated board for external heat preservation of the outer wall is usually manufactured by a surface inorganic decoration layer and an organic heat preservation board body, because the heat preservation system of the whole outer wall is formed by splicing and sticking a plurality of heat preservation decoration integrated boards and anchoring the supporting piece and the inner fastener, when the outer side of the wall is fired, although the surface inorganic decoration layer cannot be burned, the temperature of flame can be quickly transmitted to the organic heat preservation board body through the surface inorganic decoration layer, so that the organic heat preservation board body is melted towards the direction of the wall, and the surface inorganic decoration layer is made to fall off and fall down. When the temperature reaches the ignition point of the organic heat-insulating plate body, the plate body can be burnt, so that the heat-insulating system is collapsed, and in addition, smoke toxicity generated during the burning of the plate body can not only endanger the personal safety, but also pollute the environment.
Disclosure of Invention
In order to overcome the defects that the heat-insulation and decoration integrated plate for external heat insulation of the external wall is easy to burn and fall off and falls down when a fire disaster occurs in the background technology, so that the safety of life and property is threatened and the environment is polluted, the invention provides a fireproof nail which can ensure that the heat-insulation and decoration integrated plate does not burn and fall off when the fire disaster occurs and a heat-insulation system does not collapse.
The technical scheme of the fireproof nail is that the fireproof nail comprises a spring, a connecting piece and a bolt, wherein the connecting piece is connected with the spring and the bolt, the root of the spring is wound outside the connecting piece in a rotating mode, one end of the bolt is screwed into the connecting piece, and the other end of the bolt is used for being anchored on an outer wall.
The connecting piece is made of metal materials or refractory ceramic materials, and threads matched with the spring and the bolt are arranged on the inner side and the outer side of the connecting piece.
One end of the fire-proof nail provided with the spring and the connecting piece is arranged in the heat-preservation decoration integrated plate, the head of the spring is positioned in the surface inorganic decoration layer, and the exposed part of one end provided with the bolt is used for anchoring on the outer wall.
The invention utilizes the supporting function of the fireproof nail, when the building outer wall catches fire, the inorganic decorative layer on the surface of the heat-preservation decorative integrated plate can not move towards the wall body along with the melting of the organic heat-preservation plate, so that a cavity is formed between the heat-preservation decorative integrated plate and the outer wall, when the inorganic decorative layer on the surface falls down due to the melting failure of the jointing agent, the falling force can break through the compression-resistant threshold value of the spring to form an air gap at the upper end of the heat-preservation decorative integrated plate, and the high-temperature gas in the cavity can be continuously discharged upwards from the air gap, so that the temperature born by the organic heat-preservation plate can be effectively reduced, the ignition point can not be reached, the heat-preservation decorative integrated plate can be ensured not to burn and fall off, the smoke and smoke toxicity can not be generated, the safety of life and.
Drawings
FIG. 1 is a schematic view of a fire stop nail;
fig. 2 is an application schematic diagram of the fire-retardant nail, and the diagram shows the state of the fire-retardant nail arranged in the heat-insulating and decorating integrated plate and the state of the heat-insulating and decorating integrated plate when being adhered to the outer wall and anchored by the fire-retardant nail.
In the figure: 1 fireproof nail, 2 springs, 3 connecting pieces, 4 bolts, 5 external walls, 6 heat-preservation decoration integrated plates, 7 surface inorganic decoration layers, 8 organic heat-preservation plate bodies, 9 adhesive mortar and 10 anchoring holes
Detailed Description
The present invention will be described in detail below by way of examples with reference to the accompanying drawings.
As shown in fig. 1, the fire prevention nail 1 comprises a spring 2, a connecting piece 3 and a bolt 4, wherein the connecting piece 3 is connected with the spring 2 and the bolt 4, the root of the spring 2 is screwed outside the connecting piece 3, one end of the bolt 4 is screwed inside the connecting piece 3, and the other end of the bolt 4 is used for anchoring on an outer wall 5.
The connecting piece 3 is made of metal materials or refractory ceramic materials, and threads matched with the spring 2 and the bolt 4 are arranged on the inner side and the outer side of the connecting piece 3.
As shown in fig. 2, one end of the fire nail 1, which is provided with the spring 2 and the connecting piece 3, is arranged in the heat insulation and decoration integrated plate 6, the end of the spring 2 is positioned in the inorganic decoration layer 7 on the outer side of the heat insulation and decoration integrated plate 6, the bolt 4 penetrates through the organic heat insulation plate 8, the heat insulation and decoration integrated plate 6 is adhered to the outer wall 5 by using the adhesive mortar 9, and the exposed bolt 4 is inserted into the anchoring hole 10 of the outer wall body to be fixed in a pouring anchoring mode.
After the technical scheme of the invention is adopted, due to the supporting function of the fireproof nail 1, the surface inorganic decoration layer 7 can not move towards the wall body direction along with the melting of the organic heat preservation plate body 8, so that a cavity is formed between the heat preservation decoration integrated plate 6 and the outer wall 5, at the moment, the glue type jointing agent between each heat preservation decoration integrated plate 6 is softened under the direct action of flame and loses the bonding effect, so that the surface inorganic decoration layer 7 falls, when the falling force of the surface inorganic decoration layer 7 breaks through the compression resistance threshold of the spring 2, an air gap is formed at the upper end of the heat preservation decoration integrated plate 6, the high-temperature gas in the cavity can be guided by the air gap to be continuously discharged upwards, the temperature born by the organic heat preservation plate body 8 in the cavity is effectively reduced, the ignition point of the heat preservation decoration integrated plate body can not be reached, and the heat preservation decoration integrated plate 6 can not burn and fall off, smoke and smoke toxicity can not be generated, the life and property safety can be ensured, and the environmental pollution is avoided.
