Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to an explosion-proof and heat-insulating exterior wall structure. Background Technology

[0002] A blast relief wall is a wall system specifically designed to protect buildings and their personnel and equipment in the event of an explosion. Its basic principle is that, upon the occurrence of an explosion, a specific mechanism allows the wall to partially or completely open, releasing the high-pressure gases produced by the explosion and reducing damage to the building structure and potential casualties. Explosion relief walls are typically installed in industrial facilities prone to explosion, such as chemical plants, oil storage facilities, and military installations.

[0003] As explosion venting wall technology continues to develop, new materials for explosion venting walls have emerged, featuring lightweight, heat insulation, thermal insulation, and fire resistance. However, these new materials with thermal insulation properties are relatively expensive and are not yet widely used in the construction market.

[0004] Expanded stone explosion venting panels are a traditional type of explosion venting panel, widely used and relatively inexpensive. However, they are generally used in lightweight explosion venting panels, often suffering from insufficient strength and lacking thermal insulation properties. Utility Model Content

[0005] Based on the above technical problems, the purpose of this utility model is to provide a building exterior wall structure that simultaneously meets the requirements of explosion venting and thermal insulation, while also being simple to construct, highly operable, and inexpensive. To achieve the above objective, this utility model provides the following technical solution:

[0006] An explosion-proof and heat-insulating exterior wall structure includes: an explosion-proof board layer and a rock wool layer; wherein the explosion-proof board layer includes an expanded stone explosion-proof board, a C-shaped steel strip wrapped around the outer edge of the expanded stone explosion-proof board, and self-tapping screws fixed to the C-shaped steel strip; the head side of the self-tapping screw is fixed to the C-shaped steel strip, and the tip of the self-tapping screw faces outward; the rock wool layer includes rock wool, a wire mesh, and rock wool nail heads; the rock wool is inserted into the explosion-proof board layer from the tip of the self-tapping screw, and the wire mesh is pressed in from the tip side of the self-tapping screw and then connected to the rock wool; the rock wool nail heads are tightened to the tips of the screws, thereby fixing the rock wool layer to the explosion-proof board layer.

[0007] Preferably, the wire mesh is galvanized wire mesh.

[0008] Preferably, the surface of the expanded stone explosion relief plate in contact with the rock wool is also coated with waterproof mortar.

[0009] Preferably, a composite layer is provided on the outer side of the rock wool layer, and the composite layer includes, from one side of the rock wool layer outward: water-resistant putty, cement mortar leveling layer, alkali-resistant fiberglass mesh layer and paint finish.

[0010] Preferably, the alkali-resistant fiberglass mesh layer comprises two layers, each layer consisting of an external thermal insulation plaster and an embedded alkali-resistant fiberglass mesh.

[0011] Preferably, the self-tapping screws are arranged at equal intervals on the C-shaped steel.

[0012] Preferably, the head of the self-tapping screw is bonded to the C-shaped steel with metal adhesive.

[0013] This invention takes into account the special function of the explosion relief plate. After the expanded stone explosion relief plate is pasted with rock wool, it is sent to a qualified laboratory for explosion relief performance testing to meet the relevant requirements.

[0014] Compared with new materials for explosion-proof walls that have thermal insulation properties, this utility model has at least the following beneficial effects:

[0015] (1) This utility model ingeniously combines the expanded stone explosion relief board with rock wool insulation, overcomes the defect of insufficient material strength of the expanded stone explosion relief board itself, and uses the C-shaped steel outer frame of the expanded stone explosion relief board as the attachment point of the external wall insulation rock wool.

[0016] (2) The self-tapping screw of this utility model is fixed together with the explosion relief plate and C-shaped steel, and the self-tapping screw tip faces outward, making it very convenient to install rock wool. The overall construction only requires common tools found on general construction sites, making the construction simple and highly operable, thus effectively shortening the construction period of the exterior wall.

[0017] (3) This utility model has low cost and is economical and practical. Attached Figure Description
