Description

Technical Field

[0001] The invention relates to the technical field of energy-saving wall construction, and in particular to a prefabricated concrete sandwich insulation exterior wall panel. Background Art

[0002] The main problems and disadvantages of traditional sandwich insulation exterior wall panels are as follows:

[0003] A. Complicated connection structure: Traditional sandwich insulation exterior wall panels usually use steel truss connectors, which are not convenient in production and combination, increasing the complexity and construction period of the construction.

[0004] B. Limiting the choice of thermal insulation materials: The choice of thermal insulation materials for traditional thermal insulation exterior wall panels is greatly restricted. Usually only one material can be used as the middle insulation layer, making it difficult to achieve the best balance between economy and environmental protection.

[0005] C. Efficiency and cost issues: Traditional construction methods may result in slow construction, high labor costs, and waste of materials.

[0006] To solve the above problems, the existing technology requires complicated construction procedures, which leads to expensive construction costs and long construction time. In addition, the traditional method limits the choice of insulation materials and is difficult to meet the requirements of different projects. Summary of the invention

[0007] The purpose of the present invention is to provide a prefabricated concrete sandwich insulation exterior wall panel to solve the problems existing in the prior art.

[0008] The technical solution adopted to achieve the purpose of the present invention is as follows: a prefabricated concrete sandwich insulation exterior wall panel, including a concrete outer blade, an insulation board, studs I, studs II and a concrete inner blade.

[0009] The insulation board includes a corrugated steel sheet, a first layer of heat insulation material and a second layer of heat insulation material. The corrugated steel sheet forms a wavy cross section along the vertical direction. The wavy cross section is a trapezoid. The corrugated steel sheet has a wave crest section and a wave trough section that appear at intervals from each other. The wall outer side of the corrugated steel sheet is filled with a first layer of heat insulation material. The first layer of heat insulation material is completely filled with the wave section on the wall outer side. The wall inner side of the corrugated steel sheet is filled with a second layer of heat insulation material. The second layer of heat insulation material is completely filled with the wave section on the wall inner side. The corrugated steel sheet, the first layer of heat insulation material and the second layer of heat insulation material together form a straight insulation board. A stud I is arranged on the straight part of the plate surface of the wave trough section. The stud I extends to the outside of the wall. A stud II is arranged on the straight part of the plate surface of the wave crest section. The stud II extends to the inside of the wall.

[0010] The concrete outer blade, insulation board and concrete inner blade are arranged in sequence from outside to inside. The straight part of the trough section touches the concrete outer blade. The straight part of the peak section touches the concrete inner blade. The stud I is embedded in the concrete outer blade. The stud II is embedded in the concrete inner blade.

[0011] Furthermore, the concrete outer blade plate and the concrete inner blade plate are made of polypropylene fiber concrete.

[0012] Furthermore, the first layer of thermal insulation material and the second layer of thermal insulation material are fixed to the corrugated steel plate by means of an adhesive.

[0013] Furthermore, the thickness of the concrete outer blade is 60 mm, the thickness of the concrete inner blade is 60 mm, and the thickness of the insulation board is 50 mm.

[0014] Furthermore, the bolts I and II are welded to the corrugated steel plate.

[0015] Furthermore, the first layer of thermal insulation material is selected from polystyrene board, polyurethane foam, glass wool or rock wool.

[0016] Furthermore, the second layer of thermal insulation material is selected from polystyrene board, polyurethane foam, glass wool or rock wool.

[0017] The technical effect of the present invention is unquestionable: the polypropylene fiber concrete blades and the insulation layer on both sides are connected together by corrugated steel plates and bolts, thereby simplifying the connection structure and improving the construction efficiency. In addition, the use of inner and outer double-layer thermal insulation materials increases the flexibility of the insulation materials, which can better meet the needs of economy and environmental protection.

[0023] The insulation board includes a corrugated steel plate 2, a first layer of heat insulation material 4 and a second layer of heat insulation material 5. The corrugated steel plate 2 forms a corrugated section along the vertical direction. The corrugated section is a trapezoid. The corrugated steel plate 2 has a wave crest section and a wave trough section that appear at intervals. The outer side of the wall of the corrugated steel plate 2 is filled with a first layer of heat insulation material 4. The first layer of heat insulation material 4 is completely filled with the corrugated section of the outer side of the wall. The inner side of the wall of the corrugated steel plate 2 is filled with a second layer of heat insulation material 5. The second layer of heat insulation material 5 is completely filled with the corrugated section of the inner side of the wall. The corrugated steel plate 2, the first layer of heat insulation material 4 and the second layer of heat insulation material 5 together form a straight insulation board. With the presence of the corrugated steel plate, the heat insulation layer of the wall is divided into an inner and outer double-layer structure, allowing the use of different types of heat insulation materials, and having greater flexibility. The best heat insulation material can be selected according to different projects and requirements to achieve the best energy-saving and environmental protection effects. The straight part of the trough section is provided with a bolt I3, which extends to the outside of the wall. The straight part of the trough section is provided with a bolt II30, which extends to the inside of the wall.

[0024] The concrete outer blade 1, the insulation board and the concrete inner blade 6 are arranged in sequence from the outside to the inside. The straight part of the trough section touches the concrete outer blade 1. The straight part of the peak section touches the concrete inner blade 6. The stud I3 is embedded in the concrete outer blade 1. The stud II30 is embedded in the concrete inner blade 6. The polypropylene fiber concrete outer blade and inner blade are connected to the corrugated steel plate through the studs. The stud rod and the corrugated steel plate bear the shear force and bending force of the wall.

[0025] This embodiment aims to solve the connection and construction efficiency problems between traditional building exterior wall insulation materials and concrete, while providing more flexible insulation material selection to improve the energy saving and environmental protection of the wall.
