Description

Technical Field

[0001] The invention relates to the field of concrete product manufacturing, in particular to a production and assembly process of a prefabricated enclosure. Background Art

[0002] Prefabricated fences are made of cement fence panels. Prefabricated component combined fences are a kind of temporary engineering fences made of magnesium chloride, perlite, sand, cement, etc. according to scientific proportions and manufactured through special production processes. Not only are they beautiful in appearance and environmentally friendly, but they are also easy to construct and low in cost. They have become the most ideal substitute for clay bricks and concrete fences and can be widely used in various construction engineering fields such as construction sites, urban construction, environmental beautification, and industrial technology transformation.

[0003] This prefabricated cement fence board is different from the common brick fence. A 5cm thick fence board (rectangular board) is 2 meters long and 50cm wide. If you want to build a 2-meter high prefabricated cement fence, you need four of these boards to build it up. If you want 2.5 meters, you need five boards. The total height of the prefabricated cement fence column plus the underground embedded legs, there are slots on the inside of the column. When installing the prefabricated cement fence, the cement board is directly clamped with the slots.

[0004] Disadvantages: 1. High initial cost, derived from material cost and manufacturing cost. 2. Transportation restrictions, mainly due to weight and sturdiness restrictions. 3. Precision installation and high construction requirements. 4. Difficulty in transformation, once installed, not easy to transform and maintain. 5. Less diversity, the prefabricated size and style may not be suitable for site requirements. 6. Joint problems, requiring a high level of professionalism from the staff, otherwise problems such as sound insulation and water seepage will occur. 7. Structural connection problems, requiring connection to the site's structural system, increasing the difficulty of design and construction.

[0005] The structure of prefabricated cement fences includes rectangular panels and columns, which are made using traditional molds. The production efficiency is slow, and the products cannot be stacked while waiting for them to dry. Stacking requires a large area. The quality strength is insufficient, the bearing capacity is insufficient, the concrete is not dense, and there are many honeycomb pores. They are inconvenient to transport, are easily damaged due to lack of strength, and cannot bear the load to be stacked high. Summary of the invention

[0006] The purpose of the present invention is to provide a production and assembly process for a prefabricated enclosure with high strength, reduced production cost, improved production efficiency, quick assembly and convenient transportation.

[0007] The present invention is a production and assembly process of a prefabricated enclosure, the steps of which are as follows:

[0008] A. Production process:

[0009] ① The overall forming of the column is produced by a single mold. One mold can produce and demould 7 single-sided columns at the same time. Two single-sided columns are fixed with screws to form a complete finished column;

[0010] The dimensions of the assembled column are: 3000mm high, 130mm wide, and 130mm thick. The mold design requires that the column can be adjusted to any size within the 3000mm height.

[0011] ② Rectangular panels: produced by a single mold. One mold can produce and demold 2 panels at the same time, and each panel can be used as an independent panel;

[0012] Rectangular panel size: 2400mm long, 500mm high, 35mm thick. The mold design requires the panel to be 2400mm long and 500mm high. The length and height can be adjusted arbitrarily.

[0013] B. Assembly process:

[0014] The column is combined with the rectangular plate: two single sides are assembled into shape, and holes are dug 60 cm from the ground to the bottom. After the columns are assembled, grooves for fixing the thickness of the rectangular plate are reserved on both sides. The rectangular plates are stacked up along the bottom of the column slots to be parallel to the top; then the column screws are fixed and locked, and the 60 cm pre-buried hole empty space is poured with concrete to complete the installation.

[0015] The production process of the present invention adopts a mechanical automatic production line, a dry production process, and a water jet engraving steel mold integral forming process. Raw material formula: medium fine sand, 05 guami stone, PO42.5 or above grade cement, polyoxyacid water reducer, national standard steel bar. Details are as follows:

[0016] ① The concrete batching ratio is set by computer to ensure uniform and standard mix.

[0017] ② Clean the mold and spray the release agent evenly inside the mold.

[0018] ③ The steel bars are laid in the mold without any de-welding and the upper and lower concrete protective layers are more than 1 cm.

[0019] ④ Concrete laying: evenly transport the mixed concrete into the mold, manually level the concrete around the mold to ensure that the overall concrete is laid evenly.

[0020] ⑤ The high-frequency motor vibrates the concrete to make it dense as a whole, reduce honeycomb pores, mechanically grind the mold surface, and manually polish the entire surface to ensure that the concrete surface is consistent with the mold surface.

[0021] ⑥ Concrete demoulding, mechanical air pressure control, to prevent demoulding deformation, after demoulding, the back of the concrete is filled with grout and polished.

[0022] ⑦ The concrete is steam-oxygenated and the formed rectangular panels are sealed and maintained in the production channel for more than 6 hours to ensure the high strength of the concrete.

[0023] ⑧The finished products are finely polished with 45° rounded corners, packed into bundles and stacked.

[0024] ⑨ The product is watered for maintenance, a sun-proof net is laid on the surface, and water is applied manually or with equipment 8-10 times a day to ensure that every corner of the product is watered thoroughly.

[0025] In summary, the beneficial effects of the present invention are reducing production costs and product quality, improving production efficiency, quick assembly, convenient transportation, and high strength. DETAILED DESCRIPTION
