Background
The fabricated building is an important direction for transformation and upgrading of the building industry, and except fabricated concrete and steel structure main bodies, the novel light wall material is more and more emphasized as an important component in a 'enclosure wall and inner partition wall system' of the fabricated building. Autoclaved aerated concrete (ALC) wallboard is the most elegant representative of novel light wall material, ALC is a light porous building material, and the lightweight porous novel green environment-friendly building material is prepared by taking cement, lime, quartz sand, gas generating material and the like as raw materials through the working procedures of grinding, proportioning, pouring, cutting, autoclaved curing, milling and the like.
The ALC wallboard needs to be provided with a pipeline groove or a hole for installing cables, optical cables and the like, and the traditional construction mode is to manually cut the pipeline groove, bury the pipeline and finally repair the wall surface with mortar and the like. In the traditional construction process, the workload is large, the dust is large, more decoration garbage and decoration dust are generated, wet operation is needed, the labor cost is high, and the construction period is also consumed. The Chinese patent application with publication number CN109016126A and publication date 2018.12.18 discloses a method for pre-burying a pipeline based on an assembled building wallboard, which comprises the following steps: firstly, establishing a model, and carrying out plate pre-typesetting and virtual positioning of a pipeline embedded part; then, intercepting the pipeline embedded part and arranging the pipeline embedded part; and finally, manufacturing a finished wallboard, and forming a plate pipeline hole at the position where the pipeline embedded part is arranged. Wherein, the pipeline embedded part is a high-temperature resistant pipe, a hot-melting bar or a smooth metal bar which can be drawn out. The ALC ribbon needs to be steamed at high temperature (180-. The pipeline embedded part is made of metal pipes, so the cost is high.
With the vigorous promotion of China on the assembly type building, the assembly rate becomes a quantitative index for measuring the assembly type building, the assembly type building puts higher requirements on the integration of the pipeline of the inner partition wall, and the ALC board is difficult to realize the integration of the pipeline of the ALC board and has higher cost due to the complex production process of the ALC board.

Detailed Description
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.
An absorption type ALC plate pipeline integrated production method comprises the steps of firstly, fixing a rod-shaped loose body 5 and a block-shaped loose body 6 at a designed position of a steel bar cage 4 by a fixing clamp 7 after the steel bar cage 4 is manufactured, immersing the rod-shaped loose body and the block-shaped loose body into a mould in which ALC slurry is poured, sending the rod-shaped loose body and the block-shaped loose body into a static curing chamber for static curing (the temperature of the static curing chamber is 55-60 ℃ and the normal pressure is normal), then cutting the rod-shaped loose body and the block-shaped loose body, sending the cut rod-shaped loose body into a steam curing kettle (the temperature in the kettle is increased from room. In the steam curing process, when the temperature reaches the melting temperature of the rod-shaped loose body 5 and the block-shaped loose body 6, the rod-shaped loose body 5 and the block-shaped loose body 6 are melted, at the moment, the ALC plate 1 reaches a certain strength, and a cavity formed after melting is completely reserved to form the required wire pipe hole 2 and the required bottom box cavity 3, as shown in FIG. 1.
Specifically, as shown in fig. 2, a rod-shaped loose body 5 and a block-shaped loose body 6 are fixed on the reinforcement cage 4, and the rod-shaped loose body 5 and the block-shaped loose body 6 are required to be made of materials with melting points of 60-200 ℃ through foaming. For example, it may be made of sponge, polyvinyl chloride, polyethylene, polypropylene, polystyrene, polyester resin, or the like, by foaming.
The material is foamed into a loose body, so that on one hand, the material occupies a small volume after being subsequently melted, and the pore-forming quality of the line pipe is not influenced; on the other hand, the cost is low. It is conventional in the art how to foam sponges, polyvinyl chloride, polyethylene, polypropylene, polystyrene, or polyester resins into a loose mass. The raw materials produced by the materials such as polyvinyl chloride, polyethylene, polypropylene, polystyrene and polyester resin are unfoamed, but are generally used foamed products after secondary processing, and the foamed products are used in the invention.
In this embodiment, the rod-shaped loose body 5 and the block-shaped loose body 6 are fixed on the reinforcement cage 4 at a predetermined position of the ALC plate 1 by using the fixing clip 7. When the ALC board 1 is steamed, the temperature is increased, and the highest temperature can reach more than 200 ℃. Sponge, polyvinyl chloride, polyethylene, polypropylene, polystyrene or polyester resin is softened and melted due to the fact that the sponge, polyvinyl chloride, polyethylene, polypropylene, polystyrene or polyester resin cannot resist high temperature, the melted product flows into the pores of the ALC plate 1 nearby, and the original position of the ALC plate forms a cavity in the original shape, so that the bobbin hole 2 or the bottom box cavity 3 is formed. In addition, the above material is a poor conductor of heat, and hardly affects the sound-insulating and heat-insulating performance of the ALC board 1.
As shown in fig. 4, the fixing clip 7 is composed of a non-closed round steel wire head (the diameter of the steel wire is 0.1-1mm, and the diameter of the non-closed round is 20-50mm) and two welded thin iron wire tails (the diameter is 0.1-0.5mm, and the length is 15-100mm), and the head of the fixing clip 7 can be adjusted according to the requirement.
The rod-shaped loose body 5 and the block-shaped loose body 6 can be connected by glue or integrally formed, the rod-shaped loose body 5 is placed in the middle of the reinforcement cage 4 of the ALC plate 1, the distance between the outer edge of the square block and the surface of the ALC plate is controlled to be 0-10mm, then the rod-shaped loose body 5 is clamped by the head of the fixing clamp 7, the tail of the fixing clamp 7 is tied on the reinforcement cage 4 of the ALC plate, and as shown in figure 3, one fixing clamp 7 is tied at intervals of 100mm and 500 mm.
Every ALC board 1 can not have more than 2 spool, probably all has the wire pipe in both sides, will stagger the typesetting, and the square probably has the polylith side by side, all connects through glue, must stagger the reinforcing bar of steel reinforcement cage.
The molten liquid flows out to form holes and cavities when the materials are cured, and the remaining liquid of the foaming materials after the melting is small, and the molten liquid flows into the holes to be absorbed because the ALC plate 1 is a porous substance when the filling materials are molten.
The above-described embodiments are set forth so that this disclosure will be thorough and complete, and will not be limited by any theory presented in the preceding claims, which may suggest themselves to those skilled in the art after reading this disclosure and all equivalents thereof that fall within the scope of the invention as defined in the claims appended hereto.
