Abstract
Description
Technical Field
[0001] This utility model relates to the field of aerated concrete block mold technology, and in particular to a block mold for processing aerated concrete blocks. Background Technology
[0002] Autoclaved aerated concrete (AAC) blocks are a new type of building material that is lightweight, porous, has excellent thermal insulation and fire resistance, can be nailed, sawed, and planed, and has a certain degree of earthquake resistance. They are widely used in high-rise frame or balcony ground structure buildings. Multiple blocks can be stacked together to form flower beds, balconies, etc. It is not only a high-quality new building material, but also has significant environmental advantages.
[0003] In the existing technology, in order to improve the production efficiency of this new type of building material, aerated concrete is usually injected into the mold groove of a single block mold and waited for it to be formed into a precast block. Then, the hardness of the precast aerated concrete block formed in the single mold groove is tested, and mass production will only begin after the test is passed.
[0004] However, traditional monolithic molds cannot perform non-destructive testing on the distribution of pores and density uniformity inside the blocks, and can only rely on destructive sampling inspections in the later stages. In addition, the molded aerated concrete blocks are not easy to detach from the mold, which limits their production efficiency. Utility Model Content
[0005] The purpose of this invention is to solve the problem that the existing technology cannot perform non-destructive testing on the distribution of pores and density uniformity inside aerated concrete blocks, and to propose a block mold for processing aerated concrete blocks.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A block mold for processing aerated concrete blocks includes a bottom support member. The surface of the bottom support member forms a horizontal bearing plane. At least four sets of side plates are provided on the edge of the bearing plane. Each set of side plates is connected to each other to form a casting cavity. A three-dimensional component is provided in the casting cavity. The height of the three-dimensional component is the same as the height of the side plates.
[0008] In order to form a specific shape after solidification of aerated concrete, preferably, the side plate includes a vertical frame, the bottom of which is vertically connected to the edge of the bearing plane, and a tip is provided between adjacent vertical frames, with the tip of the tip facing the casting cavity.
[0009] To facilitate smoothing of the concrete surface, the top of the vertical frame is provided with an outwardly extending frame eave, the plane of which is parallel to the bearing plane.
[0010] To facilitate non-destructive testing of the interior of the block and rapid demolding, preferably, the three-dimensional component includes a hollow pointed cone fixedly connected to the bearing plane.
[0011] Furthermore, the ratio of the bottom cross-sectional area to the top cross-sectional area of the hollow cone is 3:1.
[0012] To facilitate non-destructive testing of the interior of the block and rapid demolding, preferably, the three-dimensional component includes a hollow columnar cone fixedly connected to the bearing plane.
[0013] Furthermore, the ratio of the bottom cross-sectional area to the top cross-sectional area of the hollow cylindrical cone is 2:1.
[0014] Compared with the prior art, the present invention provides a block mold for processing aerated concrete blocks, which has the following beneficial effects:
[0015] 1. The block mold for processing aerated concrete blocks can ensure smooth flow of slurry and form hollow cone-shaped holes inside the formed blocks through the hollow cone or hollow column cone on the bearing plane. This allows for non-destructive testing of the distribution of pores and density uniformity inside the blocks without relying on subsequent destructive sampling inspections.
[0016] 2. The mold for processing aerated concrete blocks, through a boron steel vertical frame vertically connected to the surface of the bottom support, can work in conjunction with a hollow pointed cone or hollow column cone to achieve rapid demolding of the formed aerated concrete blocks.
[0017] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model achieves rapid demolding of aerated concrete blocks after molding through the synergistic effect of the vertical frame and hollow pointed cones or hollow cylindrical cones. At the same time, this design also ensures the smooth flow of slurry and forms hollow pointed cones or hollow cylindrical cones-shaped holes inside the molded blocks. Through these holes, the distribution of pores and density uniformity inside the blocks can be non-destructively tested, thereby avoiding the need for subsequent destructive sampling inspections.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] Autoclaved aerated concrete (AAC) blocks are a new type of building material that is lightweight, porous, has excellent thermal insulation and fire resistance, can be nailed, sawed, and planed, and has a certain degree of earthquake resistance. They are widely used in high-rise frame or balcony ground structure buildings. Multiple blocks can be stacked together to form flower beds, balconies, etc. Typically, AAC is injected into the mold groove of a single block mold and left to solidify, forming precast blocks. Subsequently, the hardness of the precast AAC blocks formed in the single mold groove is tested. Only after passing the test will mass production begin. However, traditional monolithic molds cannot perform non-destructive testing on the distribution of pores and density uniformity inside the block, and can only rely on destructive sampling inspections later. In addition, the formed AAC blocks are not easy to detach from the mold.
[0028] Example 1:
[0029] Reference Figure 1 , Figure 3 and Figure 5 A mold for processing aerated concrete blocks includes a bottom support 1 with an X-shaped cross-section. A horizontal bearing plane is formed on the surface of the bottom support 1. Five sets of side plates are arranged along the edge of the bearing plane, with each set of side plates interconnected to form a casting cavity. The shape of the casting cavity is designed to accommodate the injected aerated concrete material. The height of the side plates can be adjusted according to actual needs to ensure that the formed aerated concrete blocks have the required thickness. In addition, the inner wall of the side plates is designed with a smooth surface to reduce friction with the aerated concrete material, facilitating the smooth removal of the formed blocks from the mold. Each set of side plates is connected by welding to ensure the stability and integrity of the mold structure. The mold includes vertical frames 2, the bottom of which is vertically connected to the edge of the bearing plane. A pointed tip 3 is provided between adjacent vertical frames 2, with the end of the tip 3 facing the casting cavity. The design of the tip 3 not only enhances the structural strength of the mold but also allows it to form a special block shape after casting. The vertical frames 2 are made of boron steel, increasing their fatigue life to 2000 cycles. A tungsten carbide coating is laser-laminated on the inner wall of the vertical frames 2, improving the mold's wear resistance and corrosion resistance, and extending its service life. The tungsten carbide coating has high hardness, high wear resistance, and high corrosion resistance, maintaining the smoothness of the mold's inner wall during long-term use, further reducing friction with the aerated concrete material, thus enabling rapid demolding of the formed blocks.
[0030] Furthermore, the entire device can be made of plastic, which also possesses high strength and wear resistance, and is relatively inexpensive, further reducing mold manufacturing costs. Additionally, plastic has a degree of elasticity, allowing it to accommodate material expansion during casting and minimizing the risk of mold damage. Moreover, plastic molds have a short processing cycle, enabling rapid production in large quantities to meet the demands of mass production.
[0031] In the above scheme, a three-dimensional component is installed inside the casting cavity. The height of the three-dimensional component is the same as the height of the side plate component. The three-dimensional component includes a hollow cone 4 fixedly connected to the bearing plane. The ratio of the cross-sectional area of the bottom surface of the hollow cone 4 to the cross-sectional area of the top surface is 3:1. The hollow cone 4 adopts a hollow thin-walled structure design, and the wall thickness of the bottom support 1, the vertical frame 2, and the hollow cone 4 is controlled between 1mm and 4mm. The thickness in this device is 3mm, thereby reducing the overall weight. The cone angle range is 40°-70°, and the cone angle in this device is 65°, ensuring smooth slurry flow and forming holes in the shape of the hollow cone 4 inside the formed block. This allows for the analysis of the internal pores of the block through the holes. Non-destructive testing of fabric density uniformity is performed without relying on subsequent destructive sampling. An outwardly extending frame 201 is set at the top of the vertical frame 2. The plane of the frame 201 is parallel to the bearing plane. When aerated concrete is injected into the cavity, a trowel can be placed on the frame 201 to smooth the surface of the aerated concrete, ensuring that the aerated concrete is evenly distributed in the mold and the surface is flat. The design of the frame 201 not only improves the ease of operation, but also ensures the quality of the block surface, reduces subsequent processing steps and costs. In addition, the frame 201 makes it easy for operators to hold the trowel for smoothing operations without hindering the normal use of the mold and the forming effect of the block.
[0032] Example 2:
[0033] Reference Figure 2 , Figure 4 and Figure 6 To perform non-destructive testing on the distribution of pores and density uniformity inside the block, the aforementioned three-dimensional component also includes a hollow column cone 5 set on the bearing plane. The ratio of the cross-sectional area of the bottom surface to the cross-sectional area of the top surface of the hollow column cone 5 is 2:1. The hollow column cone 5 adopts a hollow thin-walled structure design with a wall thickness ranging from 2mm to 4mm to reduce the overall weight. The thickness of the hollow column cone 5 in this device is 3mm, and its cone angle ranges from 40° to 70°. The cone angle in this device is 60° to ensure smooth slurry flow and to form holes in the shape of the hollow column cone 5 inside the formed block. Then, the distribution of pores and density uniformity inside the block can be non-destructively tested through the holes.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
