Description
, Concrete-filled Gypsum External Wall Board Field of the Invention The invention relates to a gypsum composite wall board, especially a concrete-filled gypsum no-cold-bridge external wall board which provides energy-savings, low consumption, is environmentally-friendly and is useful for bearing construction load.

on-site wet manual operations must be performed in large quantities, which can result in many procedures, high costs, long duration and low product quality. In particular, with current buildings, the insulation layer is added afterwards, so the insulation materials and the main buildings have different lifetimes, such that the insulation material needs to be changed repeatedly, which increases costs. In addition, the insulation materials are flammable and insecure as a result of the outdated construction processes.
Summary of the Invention The main purpose of this new invention is to overcome the above inefficiencies by providing a multi-functional concrete-filled gypsum no-cold-bridge external wall board that is made using industrialized production and integrated installation, with resulting energy-savings, low consumption, and which is environmentally-friendly.

first connection bars connect the high-strength gypsum layer, light insulation material layer and in the external wall of the high-strength gypsum reserving concrete cavity layer; second connection bars deepen into the cavity bar of the high-strength gypsum reserving concrete cavity layer. From the upper to the lower, second connection bars connect the high-strength gypsum layer, light insulation material layer and the high-strength gypsum reserving concrete cavity layer.

The purpose is to partially thicken the high-strength gypsum layer (1) to increase the connection strength between the connection bar and the high-strength gypsum plate (1).
As shown in Figure 2-4: each of the first connection bars (6) is made of 3 independent bars sticking together in row, with a first positioning plate (8) to position the first connection bar (6). Both ends of each bar of the first connection bars are divided into 4-10 vertical parts. First, heat it for forming, to make the upper part of each bar of the first connection bars (6) into a first umbrella-shape upper umbrella head (9), sticking the touching parts of the first upper umbrella (9) of the three bars to an entity (first positioning plate 8), and then the unopened ends of first connection bars (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 first and second 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 each of the first connection bars is heated and divided into a plurality of parts to form a first umbrella-shape lower umbrella head (11), sticking the touching parts of the first lower umbrella head into an entity.

The upper end of each second connection bar (7) is heated to form the second umbrella-shape upper umbrella head (12).
The part of each second 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 each second connection bar(7). Each second 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 each second connection bar is heated and split to form the second umbrella-shape lower umbrella head (15).

The purpose is to partially thicken the high-strength gypsum layer (1) to increase the connection strength between the connection bar and the high-strength gypsum plate (1).
As shown in Figure 2-4: each of the first connection bars (6) is made of 3 independent bars sticking together in row, with a first positioning plate (8) to position the first connection bar (6). Both ends of each bar of the first connection bars are divided into 4-10 vertical parts. First, heat it for forming, to make the upper part of each bar of the first connection bars (6) into a first umbrella-shape upper umbrella head (9), sticking the touching parts of the first upper umbrella (9) of the three bars to an entity (first positioning plate 8), and then the unopened ends of first connection bars (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 first and second connection bars 6 and 7.

Once in place in the insulation layer, the unopened end of each of the first connection bars is heated and divided into a plurality of parts to form a first umbrella-shape lower umbrella head (11), sticking the touching parts of the first lower umbrella head into an entity.

Each second 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 each second connection bar is heated and split to form the second umbrella-shape lower umbrella head (15). The second upper umbrella head (12) and the second 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).

6 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 first connection bars 6 and second 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 (first upper umbrella head 9 and second upper umbrella head 12 of the first connection bars and second 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 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

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
7 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.
