Problems solved by technology

[0005] The main molding method of RPC as a prefabricated component is pouring molding. The shape is generally a regular cuboid or cube. Due to the narrow thickness of the web of the I-shape, it is easy to block the material during molding, which will cause the material to fail to reach the bottom, making the formed component exist. larger defect

preparation example Construction

[0052] The present invention also provides a preparation method for the new type of inorganic composite material RPC profile, including the steps as follows:

[0053] Step (1) Put the mold according to Figure 5 Installation, the four -forming board end baffle 1 and the molding board 2 are based on the position of the corresponding fastener device 4 to fix the baffle and the molding plate of the screw.

[0054] Step (2) Install the flip mechanism 3 at the bottom of the molding board. By rotating the on both sides, the formation board 2 is the Image 6 To.

[0055] Step (3) This experiment is equipped with the pressure -resistant strength after maintenance of 200MPA, 300MPA and 400MPa RPC slurry, which can be used to prepare RPC profiles of different sizes to meet multi -directional needs. Figure 13 Essence

[0056] Step (4) Pour the prepared pulp into the mold concrete molding area, so that the center of the slurry is slightly higher than the edge of the mold, and the vibration mold...

Embodiment

[0065] Taking the preparation intensity of the workcase of 200MPa as an example, such as Figure 13 It shows that the present invention provides a production mold of RPC industrial profiles. The molds include two molding boards 2, four -forming board end baffle 1 and flip mechanism 3 (see figure 1 To. The corresponding fastening device of the molding board 2 and the baffle 1 of its end 1 is fixed through the screws, so that the four baffle 1 is fixed on the end of the two molding boards 2 to form the formation area of ​​the RPC concrete (such as such as such as such as such as the formation Figure 5 Show). Install the flip mechanism 3 at the bottom of the molding board, rotate the molding board 2 to the horizontal position (see Image 6 ), The mold is the open position. Next, pour the slurry to the concrete formation area and place the mold on the vibration platform. The center part of the slurry should be slightly higher than the edge of the mold. The rotating mold merges the mold,...

Abstract

The invention belongs to the field of preparation of inorganic composite material profiles, in particular to an overturning mold and a method for preparing inorganic composite material profiles. The mold is a cuboid structure, including two forming plates, four forming plate end baffles, and a turning structure; the forming plate end baffles are located on both sides of the end of the forming plate, and the turning mechanism is located at the center of the bottom of the forming plate; the forming plate There are fastening devices on the baffles and the end baffles to form the end sealing area; the upper part of the forming plate is provided with an extrusion port for excess material, which is used to extrude excess material and air to improve the compactness of the test piece; the lower part of the forming plate is provided with There is an inclination angle, which is used for the accumulated material on the surface of the mold to slip off when the mold is in the open position to prevent the mold from being closed. By using the method provided by the present invention to design and set the inversion structure, the problem of material blockage caused by too narrow mold webs and thus large defects in the molded parts can be effectively avoided, and the operation is simple and convenient.

Description

Technical field [0001] The present invention is a field of preparation of inorganic composite materials, which involves a flip mold and method for preparing fororganic composite materials and profiles. Background technique [0002] The profile is an object with a certain geometric shape made of iron or steel and materials with a certain strength and toughness through the process of rolling, extrusion, and casting. There are mainly the following problems in this type of material. The production process is complicated, and the corrosion of steel will cause the decline in the carrying capacity of the steel-mixed combination structure and decrease. , Increase the load. [0003] Reactive Powder Concrete (RPC) is a French after the high -strength concrete (HSC) and high -performance concrete (HPC), and the French P.richard was first proposed at the 1994 American Society of Concrete Society in 1994. A new type of cement base composite material. This type of new cement base composite mat...
