Embodiment 1

[0042] First set the bulk density to 400kg / m 3 The foamed pottery is cut into 20 small unit plates 1 with a thickness of 25cm × length 80cm × width 60cm. The structural diagram of the small unit plates 1 is as follows figure 1 shown. Place the above-mentioned unit plates horizontally on a steel platform, bond and cure the contact surface of the unit plates with polyurethane adhesive, and then open a groove 15 cm deep and 2 cm wide along the joints of the unit plates, clean the floating dust with a vacuum cleaner, and place a double-layer Φ12 The reinforced mesh sheet 3 of epoxy coating, the structural representation of reinforced mesh sheet 3 is as image 3 As shown, plug the side grooves around the side, pour self-leveling cement-based mortar binder 4, and place 160g / m on the surface 2 Alkali-resistant mesh cloth; soaked in cement-based mortar binder, the surface is smoothed, such as Figure 4 shown. After solidification, thick 5mm, wide 10cm steel strip hoop 5 is enclose...

Embodiment 2

[0044]First set the bulk density to 400kg / m 3 The foamed pottery is cut into 20 small unit plates with a thickness of 25cm × length 80cm × width 60cm. The small unit plates are cut 7mm around and 15cm in the thickness direction to form a stepped rectangular parallelepiped unit plate 2. Its structure diagram Such as figure 2 shown. Put the above-mentioned step-shaped cuboid with the big head down and the small head up on the steel platform horizontally, and assemble it into a wallboard shape of 320cm x 300cm x 25cm in thickness. The contact surface of the big cuboid is bonded and cured with epoxy resin adhesive. A groove with a depth of 15 cm and a width of 1.4 cm is formed on the head surface, and a double-layer Φ12 stainless steel steel mesh 3 is placed. The structural diagram of the steel mesh 3 is as follows image 3 As shown, plug the side grooves around the block, pour magnesium phosphate-based mortar binder, and place 200g / m2 on the surface 2 Basalt fiber mesh cloth ...

Embodiment 3

[0046] First set the bulk density to 600kg / m 3 The foamed pottery is cut into 50 unit plates with a thickness of 15cm×length 60cm×width 60cm, and the two pieces are stacked together, bonded and cured with an epoxy adhesive to form a small unit plate with a thickness of 30cm×length 60cm×width 60cm 25 pieces, the structural diagram of the unit plate is as follows figure 1 shown. Place the above-mentioned unit plates horizontally on a steel platform, bond and cure the contact surface of the unit plates with polyurethane adhesive to form a foamed ceramic plate with a length of 300cm×width 300cm×thickness 30cm, and then open a 20cm deep joint along the unit plate , 2cm wide groove, clean the floating dust with a vacuum cleaner, place Φ14 epoxy-coated steel mesh, seal the surrounding grooves, pour self-leveling cement-based mortar adhesive, and place 160g / m on the surface 2 Alkali-resistant mesh cloth, soaked in cement-based adhesive mortar, and the surface is smoothed. After sol...

Abstract

The invention relates to a lightweight insulation decorative external wall panel of rear bar planting anchoring foamed ceramics or foaming glass and a preparation method thereof and belongs to the technical field of lightweight high strength wall panel prefabricated component preparation. The external wall panel is formed through assembling foamed ceramic or foamed glass small unit plates, a steelmesh is embedded in the middle position of two adjacent unit plate joints, the unit plates are bonded with an adhesive, steel plate bars are connected with steel meshes around the external wall panel, an inner wall surface is reinforced with the fiber mesh cloth and the adhesive, and connecting pieces connected with structural members are pre-installed on the steel plate bars or the steel meshes.The external wall panel has advantages of light weight, high strength, heat insulation, decoration, fire resistance, durability, structural stability and rapid production and is quite suitable for steel structure buildings.

Description

technical field [0001] The invention relates to a light-weight thermal insulation and decorative exterior wall panel with post-planted reinforcement anchoring foam ceramics or foam glass and a preparation method thereof, belonging to the technical field of preparation of light-weight high-strength wall panel prefabricated components in the field of construction. Background technique [0002] With the development of prefabricated housing industrialization technology, prefabricated concrete wall panels have become one of the main components of prefabricated housing. Generally, concrete materials are used to prepare load-bearing and heat-insulating PC sandwich composite wall panels, which are mostly used for load-bearing components of shear walls, and the unit area density exceeds 600kg / m 2 . However, for steel structure buildings, light-weight, heat-insulating, and decorative external panels are required. Prefabricated concrete components cannot meet the design requirements d...
