As shown in Figure 1, the preferred embodiment of concrete dense column gypsum composite no-cold-bridge external wall board (composite gypsum external wall board) according to the invention is composed of a high-strength gypsum layer (1), a light insulation material layer (2), a high-strength gypsum reserving concrete cavity layer (3), and a concrete dense column inside (4), which columns are separated by a cavity bar (5) in rows. In all layers, in both the length direction and width direction, there are A connection bars (6) and B connection bars (7) distributed uniformly throughout, of which the A connection bars (6) connect the high-strength gypsum layer (1), the light insulation material layer (2) and in the external wall of the high-strength gypsum reserving concrete cavity layer and the B connection bars (7) deepens into the cavity bar (5) of the high-strength gypsum reserving concrete cavity layer (3).
4 From the outside to the inside, B connection bar (7) connects the high-strength gypsum layer (1), the light insulation material layer (2) and the high-strength gypsum reserving concrete cavity layer (3); on the light insulation material layer (2), along the width, length and depth direction of the light insulation material layer (2), A connection bar (6) and B connection bar (7) are partially heated and removed by heating iron (or by cutting off part of the light insulation material layer (2)), the heated length and width are the same as the A upper umbrella head (9) and B upper umbrella head (12) of A
connection bar (6) and B connection bar (7), the heated depth is 0.5-1cm. The purpose is to partially thicken the high-strength gypsum layer (1) to increase the io connection strength between the connection bar and the high-strength gypsum plate (1).

As shown in Figure 2-4: The A connection bar (6) is made of 3 independent connection bars sticking together in row, with A positioning plate (8) to position A
connection bar (6). Both ends of every connection bar of A connection bar are divided into 4-10 vertical parts. First, heat it for forming, to make the upper part of every connection bar of A connection bar (6) into umbrella-shape A upper umbrella head (9), sticking the touching parts of A upper umbrella (9) of the three connection bars to an entity (sticking plate 8), and then the unopened ends of A connection bar (6) are inserted through the reserving hole (10) on the light insulation material layer (2) and fixed by bonding with the same (for example, using glue or the like).
Preferably, the lightweight insulation material layer 2 is uniformly provided with preformed holes for passing through the A and B connection bars 6 and 7. Preferably the holes are evenly arranged along the length and width of the insulation material layer 2 in a desired/required pattern. Once in place in the insulation layer, the unopened end of every connection bar of A connection bar is heated and divided into a plurality of parts to form umbrella-shape A lower umbrella head (11), sticking the touching parts of A
lower umbrella head into an entity. A upper umbrella head (9) and A lower umbrella head (11) improve the connection solidity with the high-strength gypsum layer (1) and the external cavity wall of the high-strength gypsum reserving concrete cavity layer (3).

As shown in Figure 5 ¨ Figure 7, both ends of every connection bar of B
connection bar are divided into 4-10 vertical parts. On B connection bar (7), there is a B
5 positioning plate (13). The upper end of B connection bar (7) is heated to form the umbrella-shape B upper umbrella head (12). The part of B connection bar (7) to be fixed within the cavity bar (5) of the high-strength gypsum reserving concrete cavity layer is crushed into two adjacent, perpendicular and isolated sections (14), to increase the holding force of the cavity bar (5) to B connection bar (7). B
connection bar (7) passes through the respective reserving hole (10) in the light insulation material layer (2), and is fixed to it. With the same method, the lower end of B
connection bar is heated and split to form umbrella-shape B lower umbrella head (15).
B upper umbrella head (12) and B lower umbrella head (15) improve the connection solidity with the high-strength gypsum layer (1) and the high-strength gypsum reserving concrete cavity layer (3).

Preferably, the A connection bars (6) and B connection bars (7) are made of Polyvinyl chloride ("PVC"), polycarbonate ("PC"), Acrylonitrile-butadiene-styrene "ABS"), is polyamide ("PA"), polyethylence ("PE"), polypropylene ("PP"), or like material, with high strength, small section area, small conductivity, no cold bridge to ensure the insulation performance of the wall.

Preferably, the composite gypsum external wall board is manufactured as described in more detail below and with reference to Figures 8-21. First, the insulation layer 2 complete with the A connection bars 6 and B connection bars 7 is prepared as described above. A first gypsum layer is spread and screeded on a production platform 20 as shown in Fig. 8 and a layer of fibreglass 17 is pressed into the gypsum layer as shown in Fig. 9, thereby forming the high-strength gypsum board layer 1 as shown in Fig. 10. The pre-formed insulation layer 2 shown in Fig. 11 is laid onto the first gypsum layer and pressed so that the trusses (A upper umbrella head 9 and B
upper umbrella head 12 of the A connection bars and B connection bars) are inserted into the first gypsum layer as shown in Fig. 12. A second gypsym layer 24 is then spread and screeded on top of the insulation layer 2 as shown in Fig. 13.
Fibreglass 17 is spread over the surface of the second gypsum layer 24 as shown in Fig.
14 and pressed into it as shown in Fig. 15. Elongated rectangular tubes forming cavities 26 are placed in alternating rows formed between the B Connection bars 7 as shown in
6 Fig. 16. Fibreglass 17 is spread around the elongated tubes 26 as shown in Fig. 17 and then additional elongated tubes 26 are positioned within the remaining rows formed between adjacent B Connection bars 7 as shown in Fig. 18. A final gypsum layer 32 is added in order to fill the spaces between the elongated tubes 26 and to form a layer on top which is spread and screeded as shown in Fig. 19. A final layer of fiberglass 17 is spread along the gypsum layer as shown in Fig. 20 and is pressed into gypsum layer 32 to form the high-strength gypsum reserving concrete cavity layer 3. Once the gypsum sets and dries the composite gypsum external wall board is ready for use in construction. The elongated tubes form cavities 34 which can later be filled on-site with concrete to form concrete dense columns 4.

Reinforcements for the reserving cavity will be made on site, pouring together with the reinforcement concrete of the building structure, forming reinforcement concrete dense column. Both the high-strength gypsum reserving cavity layer and the reinforcement concrete dense column take the building structure stress.

The polystyrene board (or plastic extrusion plate or rock wool or fiber board) light insulation material filled in the light insulation material layer (2) reduces the plate weight and improves the insulation performance. The high-strength gypsum layer (1) and high-strength gypsum reserving concrete cavity layer (3) is preferably made of high-strength gypsum, concrete, fly ash, fiber reinforcement and waterproofing agent (or high-strength gypsum, concrete, and fiber reinforcement and waterproofing agent or high-strength gypsum, fiber reinforcement and waterproofing agent or mortar, fiber reinforcement), increasing the strength of the plate.
The described concrete dense column gypsum composite no-cold-bridge external wall board has the functions of enclosure, weight-loading, sound-proofing, insulation, seismic-protection and fire-proofing; the board of the concrete dense column gypsum composite no-cold-bridge external wall board attends the building load-bearing and seismic-protection stress. Both of the gypsum board reserving cavity board and the reinforcement concrete dense column inside attend the main structure load stress calculation.
7 The described concrete dense column gypsum composite no-cold-bridge external wall board can adjust the board type, geometric dimension of the reserving concrete cavity, reinforcement quantity of the concrete dense column and the concrete intensity according to the building structure type, building height and the different application area of the wall board to adapt to all kinds of structures and to different sized buildings. Increasing or decreasing the thickness of the light insulation material layer (2) can adapt to the different insulation performance requirements from severe cold to severe hot areas and to any specific building requirements.
In the described dense column gypsum composite no-cold-bridge external wall board, there is a light insulation material layer (2), and the A connection bar (6) and B
connection bar (7) are made of insulating materials to effectively insolate the thermal conductivity way between the inside and outside to form a no-cold-bridge structure.
The gypsum composite wall board may be manufactured using the desulfurized gypsum of a power plant as the main material. By making use of this waste product the wall board provides an environmentally-friendly, energy-saving, low consumption, light weight and high strength product. In addition, the insulation layer has the same lifetime as the main building, so there is no need to change it repeatedly, thereby reducing the maintenance costs of a building. The geometrical dimension of the concrete dense column cavity can be altered to adapt to all kinds of buildings.
Similarly, the thickness of the insulation layer can be adjusted to meet the different insulation requirements of different locales - from severe cold to severe hot areas.
The mass application on the external wall of the buildings contributes to improve the standardization, serialization, industrialized production, integrated application living operation method, improving the entire modernization level of the living house industry, with wide popularity.

It will be appreciated by those skilled in the art that the preferred and alternative embodiments have been described in some detail but that certain modifications may be practiced without departing from the principles of the invention.
