Description

Technical Field

[0001] The present invention relates to the technical field of building engineering panels, in particular to a multi-purpose prefabricated insulation panel and a manufacturing method thereof and a construction method thereof as different wall bodies. Background Art

[0002] EPS board is one of the main building materials in modern environmentally friendly and energy-saving buildings. Traditional EPS board styles are diverse and require the development of multiple sets of molds. Some boards use simple EPS foam to wrap ordinary C-shaped steel. When used as walls, there is no reliable connection between the upper and lower floors, resulting in loose connections, insufficient bearing capacity, and poor integrity.

[0003] To this end, it is necessary to research and develop a multi-purpose prefabricated insulation board and its construction process based on existing technologies, which saves molds and can be directly applied to the wall structure of low-rise or multi-story easy-to-install houses. The load-bearing performance is doubled, and it is lighter and more convenient. It completely subverts the scope of use and function of conventional EPS wall panels, and can also be used for internal and external filling walls of frame structures. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the existing technology, the present invention provides a multi-purpose prefabricated insulation board and a production method and a construction method as different walls to solve the problems of insufficient bearing capacity of existing EPS board walls and loose connections between upper and lower layers.

[0005] The technical solution is a multi-purpose prefabricated insulation panel, comprising a panel body, wherein the panel body comprises a main panel and a steel frame composited together, wherein one end of the panel body has a protruding tongue and groove and the other end corresponding to the protruding tongue and groove is provided with a recessed tongue and groove, wherein the steel frame comprises a plurality of steel keels, wherein each of the steel keels is arrayed on the same side of the main panel, wherein the steel keel is a "C"-shaped steel with an inner curled edge, and the steel frame further comprises auxiliary insulation panels including angle steels and gusset plates to form components for a stable structure, wherein the angle steels are located at the four long edges of the upper and lower end faces of the panel body and at the sides of the panel body, and cooperate with the gusset plates to form a stable panel frame.

[0006] Furthermore, each of the steel keels is a galvanized "C"-shaped steel with a specification of 100*40*10mm. When combined with the main board and used as a wall panel, it can provide greater vertical and horizontal bearing capacity of the wall compared to conventional C-shaped steel frames under the same material and cross-sectional size.

[0007] The wall panels for load-bearing walls include load-bearing wall panel units, wherein the load-bearing wall panel units include two mirror-set No. 1 panel units, each of the No. 1 panel units is a panel with a groove and a reinforcing steel belt in the middle. The No. 1 panel units are improved on the basis of the panel and use the same set of molds as the main board. The reinforcing steel belt and the steel keel are located on the same side. The side of each No. 1 panel unit with the steel keel serves as the outer side of the load-bearing wall panel unit. The groove in the middle of the two mirror-set No. 1 panel units corresponds to forming a cavity in the middle of the load-bearing wall panel unit. Uninterrupted hidden columns are set between the layers in the cavity. The hidden columns increase the bearing capacity of the wall and the stability between the wall layers, which is more conducive to the safety and stability of the multi-layer structure. Angle steel with a 90° right angle is set on the edge of the steel keel on each load-bearing wall panel unit. The steel keel fits in the angle steel groove to play a supporting and connecting role. The No. 1 panel units are connected by a patch plate.

[0008] Furthermore, in the load-bearing wall panel unit, the hidden column includes a plurality of steel bars and concrete poured between the steel bars, and each of the steel bars is located at the four corners of the central cavity of the load-bearing wall panel unit and is subjected to longitudinal force.

[0009] Furthermore, in the load-bearing wall panel unit, the hidden columns are finished steel columns.

[0010] Furthermore, the gusset plate is a steel sheet with a width of 5 mm and a thickness of 1 mm. The addition of the gusset plate increases the integrity of the wall panel and increases the load-bearing capacity of the wall panel.

[0011] A wall panel for a non-load-bearing wall with an added wind-resistant column comprises a No. 2 panel unit, which is a panel with multiple grooves and reinforcing steel strips. Each of the reinforcing steel strips is distributed on the side of the panel without a steel keel, and each of the grooves is arranged on the side where the steel keel is located and corresponds to the reinforcing steel strip. After the grooves are set in the wall panel, the corresponding position becomes relatively thinner, so it is arranged corresponding to the reinforcing steel strip to prevent the wall panel from breaking, and a square steel tube is arranged in the groove.

[0012] Furthermore, the main board can be an EPS board, a foam concrete board or a polystyrene particle foam concrete board. When the prefabricated insulation board is used as a building component, the EPS board should be modified to achieve a fire protection level not lower than B1.

[0013] Production method of multi-purpose prefabricated insulation board: S1. Complete the overall steel frame, the steel frame includes a steel keel 2 and a reinforcing steel belt 6, the number of the reinforcing steel belt 6 is determined by the structure of different wall panels and the number of grooves on the wall panels, the grooves are set according to the pre-analysis of the stress conditions of the wall panels and can be set; S2. When using EPS boards as the main boards, place the entire steel frame in the EPS board forming machine; when using concrete boards as the main boards, support the formwork; S3. Form the completed overall steel frame together with the main board 1, and reserve grooves 5 according to the number of structures of the wall panels. If not needed, no grooves need to be reserved during production. The steel frame is evenly embedded in the surface of the main board, but does not penetrate the main board 1. The main board and the steel frame are tightly connected without a cavity. The presence of the reinforcing steel belt can better ensure the integrity of the wall panel, achieve a better connection with the cast-in-place concrete, strengthen the integrity, and will not break due to grooving.

[0024] Furthermore, in the method of constructing the multi-purpose prefabricated insulation board as the load-bearing wall, the hidden column uses a finished steel column, and in step 3, the finished steel column is pushed into the reserved groove.
