specific Embodiment approach 1

[0019] Specific implementation mode one: combine Figure 1-Figure 7 Describe this embodiment, the wall panel of this embodiment includes outer layer board 1, inner layer board 2, insulation core layer, a plurality of first FRP connectors 4-1, a plurality of second FRP connectors 4-2 and a plurality of A filling layer 5, the insulation core layer includes rock wool layer 3-1 and two extruded boards or waterproof rock wool strips 3-2, rock wool layer 3-1 and two extruded boards or waterproof rock wool strips 3-2 Set between the outer layer board 1 and the inner layer board 2, each end of the rock wool layer 3-1 is provided with an extruded board or waterproof rock wool strip 3-2, and the rock wool layer 3-1 is evenly distributed with multiple Each reserved hole 6 is provided with a first boss 7 on the inner end surface of the outer layer plate 1 corresponding to each reserved hole 6, and a first boss 7 is arranged on the inner end surface of the inner layer plate 2 corresponding...

specific Embodiment approach 2

[0020] Specific implementation mode two: combination figure 2 , image 3 and Figure 4 To illustrate this embodiment, one of the two waterproof rock wool strips in this embodiment is convex, and the remaining one is concave. The shape of each rock wool strip is angular, arc-shaped or polygonal, and the waterproof rock wool strip The performance index is density ≥ 120kg / m 3 , Compressive strength ≥ 60Kpa, thermal conductivity lower than 0.04W / (m·K), water absorption < 2.0%. The design of this structure extends the length of the heat transfer path to avoid the formation of cold bridges. Other implementation manners are the same as the specific implementation manner 1.

specific Embodiment approach 3

[0021] Specific implementation mode three: combination figure 1 To illustrate this embodiment, one end of the outer layer 1 of this embodiment is set in an upper stepped shape, the other end of the outer layer 1 is set in a lower stepped shape, and the extruded board is lapped on the outer layer 1 and the inner layer 2 Above, the density of extruded board is 32-36kg / m 3 , Compressive strength ≥ 250KPa, thermal conductivity < 0.04W / m·K, water absorption < 1.0%.

[0022] The design of this structure extends the length of the heat transfer path to avoid the formation of cold bridges. The rock wool layer 3-1 is arranged in the middle of the outer layer 1, the inner layer 2 and the extruded plastic board or waterproof rock wool strip 3-2, so that it will not get wet to ensure the thermal insulation performance, and the extruded plastic board or waterproof rock wool strip 3-2 has a certain strength, avoiding the problem of extrusion deformation, and the extruded board or waterproo...

Abstract

The invention relates to a combined type unreinforced thermal-insulating sandwich external wall slab and a manufacturing method for an inner laminate and an outer laminate of the same in order to solve the problems of poor fireproof safety for the thermal insulating construction of an external wall, cracking resistance of a wall slab material, complex construction caused by the employment of a reinforced keel as well as large thickness of a surface layer and high self-weight of a wall slab caused by conventional connecting pieces. In the first scheme, one extruded sheets or waterproof rock wool bars are respectively arranged at two ends of a rock wool layer, the head of each first FRP (Fiber Reinforced Plastic) connecting piece is arranged in a first lug boss, the other end of the same is arranged at the outer part the an inner laminate after penetrating through a corresponding preserved hole and a second lug boss, the head of each second FRP connecting piece is arranged in the first lug boss, and the other end of the same is arranged in the second lug boss after penetrating the corresponding preserved hole. In the second scheme, cement, pulverized fuel ash, silver sand, swelling agent and defoaming agent are uniformly mixed in a mixing machine in sequence; and materials are discharged and molds are cast after adding water reducing agent, water and steel fiber into the mixture. The combined type unreinforced thermal-insulating sandwich external wall slab is applied to building field.

Description

technical field [0001] The invention relates to a heat-insulating non-reinforced outer wall board and a method for manufacturing the inner and outer layer boards. Background technique [0002] With the rapid development of urban construction, building exterior wall energy-saving technology and building exterior wall construction safety technology are more and more concerned by the state and users. In order to reduce the energy consumption of building exterior walls, various new building exterior wall insulation technologies have emerged in the past ten years. According to the insulation methods, they can be roughly divided into external insulation, internal insulation, and sandwich insulation. The insulation materials used are basically combustible. Type polystyrene board material. In recent years, building construction fires have emerged one after another, which has attracted great attention from the state and ministries and commissions. The relevant state departments hav...
