[0036] Preferably, a pouring port 10 is provided on the cover plate 1, and the pouring port 10 is connected to the prefabricated space. Two groups of pouring ports 10 are provided, and each group of pouring ports 10 is connected to two groups of prefabricated spaces, which can improve the pouring efficiency while ensuring uniform pouring and preventing one-sided pouring from causing uneven cooling of concrete.

[0037] Working principle: insert the epoxy resin rod 20 into the first light-transmitting hole and the second light-transmitting hole, and then pour concrete into the prefabricated space to fix the inner frame, the insulation board 4 and the epoxy resin rod 20 into shape. Since the epoxy resin rod 20 is a light-transmitting material, it can allow outdoor sunlight to penetrate into the room, increase indoor lighting, and reduce indoor lighting power consumption; at the same time, by setting the insulation board 4, the thermal insulation capacity of the light-transmitting concrete board is improved to achieve energy saving; finally, the purpose of integrating decorative beauty and building energy saving is achieved.

[0038] Furthermore, the cover plate 1 is provided with a first fixing groove 11 for inserting the upper part of the alkali-slag plate 2 and a second fixing groove 12 for inserting the upper part of the insulation plate 4; and the cover plate 1 is bolted to the alkali-slag plate 2 and the insulation plate 4.

[0039] The cover plate 1 is provided with two groups of first fixing grooves 11 , and the first fixing grooves 11 face the bottom plate 3 , and the second fixing groove 12 is located between the two groups of the first fixing grooves 11 , and the second fixing groove 12 opens toward the bottom plate 3 .

[0040] Furthermore, the bottom plate 3 is provided with a third fixing groove 30 for inserting the lower part of the alkali-slag plate 2 and a fourth fixing groove 31 for inserting the lower part of the insulation plate 4; and the bottom plate 3 is connected to the alkali-slag plate 2 and the insulation plate 4 by bolts.

[0042] Working principle: the upper end of each group of alkali-slag plates 2 is installed in the first fixing groove 11, and the lower end thereof is installed in the third fixing groove 30; the upper end of the insulation plate 4 is installed in the second fixing groove 12, and the lower end thereof is installed in the fourth fixing groove 31; the alkali-slag plate 2, the insulation plate 4, the cover plate 1 and the bottom plate 3 are fixed by bolts, and the installation efficiency can be improved and the installation accuracy can be ensured by setting the fixing groove.

[0043] Furthermore, the alkali-slag plate 2 is made of mineral powder, water glass, sodium hydroxide, water, sand, ceramsite and steel fiber.

[0046] By adding ceramsite as lightweight aggregate, the lightweight aggregate is prepared from lightweight coarse aggregate, lightweight fine aggregate or ordinary fine aggregate, cement, water, admixtures and admixtures. On the one hand, the weight of the lightweight aggregate can be reduced, making transportation and installation more convenient. On the other hand, the lightweight aggregate has good fire resistance, shock absorption and frost resistance, further improving safety.

[0047] By adding steel fibers, the bending strength and splitting tensile strength of the alkali-slag plate 2 can be improved.

[0048] Working principle: In the prior art, steel formwork is used for casting, and the steel formwork needs to be removed after casting. In this solution, alkali slag plate 2 is used instead of steel formwork, and it does not need to be removed after casting and can be directly installed, thereby improving the manufacturing and installation efficiency.
