Detailed ways

As shown in Figures 1-14, the present invention includes a load-bearing base 2 and at least one heat preservation body 1; the composite material and the "embedded" structure ensure the overall strength of the block while improving the heat preservation effect of the block.

The insulation body 1 is made of 40-60% cement, 8-15% silica fume, 3-5% hydrogen peroxide, 0.5-1% modifier and 31-38% water by weight percentage;

The load-bearing matrix 2 is composed of 20-40% of cement, 0-40% of tailings sand, 25-65% of recycled construction waste raw materials, 10-40% of fly ash, 3-5% of fibrous rod-shaped materials, peroxidized Made of hydrogen 0.10-0.40%, admixture 0.7-1.6% and water 20-36%;

Among them, silica fume is an ultrafine silicon powder material formed by rapid oxidation and condensation of SiO2 and Si gas produced during smelting ferrosilicon alloy and industrial silicon and oxygen in the air. Silica fume has a large specific surface area, which can greatly improve the consistency and foaming stability of the insulation slurry. At the same time, because of its high chemical activity, it can significantly improve the strength of the load-bearing matrix.

Modifier: The insulation body contains a large number of closed air bubbles, which not only endows it with good physical and mechanical properties and thermal performance, but also brings difficulties to production and use, and some defects may even affect its application. Therefore, additional measures must be taken to improve the stability of the slurry structure, accelerate the formation process and strength development of the structure, reduce the water absorption and shrinkage of the hardened body, adjust and optimize the pore structure and pore size of the foamed concrete, etc. Add modifiers to achieve. The modifiers used to control the formation process and pore structure of the thermal insulation body mainly include catalysts, early strength agents, accelerators, pore regulators, foam stabilizers, etc. The modifiers used to improve the performance of the thermal insulation body include dispersants , waterproofing agent, strengthening agent, anti-cracking agent, rubber powder or polymer emulsion, etc.

The fibrous rod-shaped material is made of wood stems, plant straws or artificially synthesized, its cross-sectional size is 0.5mm-2mm×0.5mm-2mm, and its length is 10mm-30mm. The fibrous rod-shaped material presents a three-dimensional structure in the load-bearing matrix. Distributed randomly, the shape of the fibrous rod-shaped material is square column or cylindrical or other irregular shapes, wherein the cross-sectional size of the columnar material is 0.5mm-2mm×0.5mm-2mm; the diameter Φ of the cylindrical material is 0.5 mm-2mm, its length is 10mm-30mm. The material can effectively inhibit the shrinkage of the hardened body of the load-bearing matrix and improve its crack resistance. At the same time, the flexural strength of the load-bearing matrix can be improved.

Tailing sand: The ore mined from metal or non-metal mines, the "waste residue" discharged after the valuable concentrate is selected by the concentrator, and the fine aggregate prepared from these waste residues.

Recycled raw materials of construction waste: waste concrete, waste bricks and tiles, waste mortar, waste stone, waste ceramics, etc. in construction waste are directly crushed to form recycled materials. The recycled raw material is composed of recycled fine aggregate and fine powder, and is used as fine aggregate and admixture for the production of load-bearing matrix.

Admixture: a mixture used to improve the properties of the load-bearing base slurry and hardened body. The main components include accelerators, foam stabilizers, dispersants, and waterproofing agents.

At least one accommodating hole is opened in the load-bearing base 2, and the heat insulating body 1 is arranged in the accommodating hole and combined with the inner wall of the accommodating hole. In actual production and processing, in order to improve the overall thermal insulation, specific strength and dimensional stability of the block, the thermal insulation body is usually set in the shape of a cylinder, a polygonal column, a truncated cone or a truncated pyramid, as shown in Figure 1-4.

In this case, the accommodating hole (that is, the insulation body is set) not only can be vertical to the horizontal plane, but also can be inclined or even horizontal. For the convenience of production, that is, the compressive and shear strength of the product, as shown in FIG. 2 , at least two accommodation holes parallel to each other are provided in the load-bearing base 2 , and the accommodation holes run through the load-bearing base 2 .

As shown in FIG. 4 , the load-bearing base 2 is provided with a plurality of accommodating holes distributed in a rectangular array.

As shown in FIG. 3 , the accommodating hole is in the shape of a cylinder with a rectangular, circular or regular polygonal cross section, or a truncated cone with a rectangular, circular or regular polygonal cross section.

The production mold comprises at least two mold boxes 3 distributed along the same circumference, a mold cover 4 that can rotate around the center of the circle and a rotary drive device 5 positioned at the center of the circle; the mold boxes 3 and the load-bearing Base 2 fits;

The inventors found the following problems when developing the product of the present invention and the trial-manufactured product: 1. Since the heat preservation body is usually located in the "middle" of the load-bearing base, when the load-bearing base is grouted, the grouting port is usually on a certain side of the heat preservation body In this way, the thermal insulation body with a relatively small density will float and shift when the load-bearing matrix is injected, which greatly affects the internal structural shape of the block and the position accuracy of the thermal insulation body after the load-bearing matrix is foamed, thus bringing 2. In order to ensure the volume of the load-bearing matrix after foaming, when injecting the load-bearing matrix slurry, if the injection amount of the slurry is not accurately measured (especially if the injection amount is insufficient), it is difficult to make a large amount on the top of the mold box. Form an "effective" bread head 20 above the surface (bread head: the part that overflows the top surface of the load-bearing matrix after foaming is completed; effective: the bottom edge of the bread head should be higher than or equal to the height of the upper edge of the mold box), Can cause the product to occur the situation that the top surface is incomplete (as shown in Figure 12, the bottom edge of bread head 20 is lower than the height of mold box 3 upper edges, after bread head 20 is cut off, will directly cause the top surface of load-bearing base 2 Incomplete and uneven, resulting in extremely high rework and scrap rates).

For the above-mentioned problem two, the following measures have been taken in this case: the injection volume should be calculated for different volumes, and the bottom edge of the bread head 20 to be formed is equal to the height of the upper edge of the mold box 3 as the minimum limit (as shown in Figure 13), with The bottom edge of the formed bread head 20 is slightly higher than the height of the upper edge of the mold box 3, which is optimal (as shown in Figure 14); finally, after the foaming of the load-bearing matrix 2 is completed, the bread head 20 is cut off to ensure the integrity of the top surface of the product sex.

The needle 420 includes a needle head 4202 and a needle seat 4201, the needle head 4202 is detachably connected to the bottom surface of the movable cover 42 through the needle seat 4201; when in use, the movable cover can be driven by a linear drive device and the positioning needle can be driven downward until The bottom surface of the needle seat is against the top surface of the thermal insulation body; in this way, the needle can be used to ensure that the thermal insulation body cannot move in the horizontal direction, and the bottom surface of the needle seat can ensure that the thermal insulation body cannot move in the vertical direction; thus, the load-bearing base When injecting and foaming, the insulation body will keep the original position without shifting under the action of the positioning pin, thus effectively ensuring the structural shape of the block after the foaming of the load-bearing matrix is completed.

The middle part of the main cover body 41 is provided with a circular through hole, and the inner diameter of the circular through hole is greater than the diameter of the circumscribed circle of the mold box 3 (in actual production, the outer top edge of the mold box is mostly rectangular, here The circumscribed circle of the rectangle is the circumscribed circle of the rectangle in the geometric sense, the diameter of the circumscribed circle is equal to the distance of the diagonal of the rectangle, and its function is to provide enough space for the foaming of the load-bearing matrix to form a bread head); the main cover The bottom of the body 41 is connected with an annular cutter 411 coaxial with the circular through hole.

In this way, after the foaming of the load-bearing matrix is completed, the motor can be turned on to make the ring cutter start to rotate; The surface height is consistent, so the redundant load-bearing base will be completely cut off when the main cover leaves the current station; thus effectively saving work steps, reducing processing difficulty and operation complexity, and greatly improving the overall work efficiency and equipment Overall reliability at runtime.
