Description

Technical Field

[0001] This application relates to the technical field of building material preparation, and particularly relates to a sandwich permeable brick mold. Background Art

[0002] The construction of sponge cities has been proposed as a new urban construction concept. The construction of sponge cities transforms the traditional "quick drainage" mode into an organic combination of "infiltration, retention, storage, purification, utilization, and drainage", greatly reducing the negative impacts brought by urbanization development and construction to the original natural hydrological characteristics and water ecological environment, so as to achieve the natural accumulation, natural infiltration, and natural purification of rainwater. Permeable paving materials (such as permeable bricks) are the key core materials for the construction of sponge cities, and their excellent characteristics are an important guarantee for "infiltration, retention, storage, and purification". Although ordinary multi-layer permeable bricks can be permeable, the connection between their base layer and surface layer is not tight. Utility Model Content

[0003] One advantage of the present utility model is to provide a sandwich permeable brick mold for preparing permeable bricks with a sandwich structure.

[0004] Another advantage of the present utility model is to provide a sandwich permeable brick mold. In order to achieve the above advantages, expensive materials or complex structures do not need to be adopted in the present utility model. Therefore, the present utility model successfully and effectively provides a solution, not only providing a simple sandwich permeable brick mold, but also increasing the practicability and reliability of the sandwich permeable brick mold.

[0005] Based on this, in order to achieve at least one of the above advantages or other advantages and purposes of the present utility model, the present utility model provides a sandwich permeable brick mold, including:

[0006] An outer mold, having an accommodation space, a first opening communicating with the accommodation space, and a second opening communicating with the accommodation space and arranged opposite to the first opening;

[0007] An inner mold, including a bearing plate detachably connected to the outer mold and blocking the first opening, and a first shaping member protruding from the bearing plate and extending into the accommodation space. The first shaping member is in clearance fit with the outer mold to form a first shaping cavity in the accommodation space that matches the base layer of the sandwich permeable brick; and

[0008] A top plate, detachably connected to the outer mold and blocking the second opening, for bearing the base layer to form a second shaping cavity in the accommodation space that matches the surface layer of the sandwich permeable brick.

[0009] In this way, the outer mold is connected to the inner mold, and the base layer of the sandwich permeable brick is prepared by pouring and stamping. The outer mold is connected to the top plate, the sandwich permeable brick mold is turned over, the connection between the outer mold and the inner mold is released, and pouring and stamping are performed to prepare a permeable brick with a sandwich structure. Different from the direct connection between the surface layer and the base layer of ordinary multi-layer permeable bricks, the sandwich permeable brick has a sandwich structure, and the contact area between the surface layer and the base layer is larger, so that the connection between the base layer and the surface layer of the sandwich permeable brick is tighter.

[0010] According to one embodiment of the present application, the inner mold also includes a second forming member protruding from the supporting plate and extending into the accommodating space, the second forming member surrounds the first forming member, the height of the second forming member is different from the height of the first forming member, and the second forming member and the first forming member together form a stepped structure.

[0011] Such arrangement enables the surface layer and the base layer of the sandwich permeable brick prepared by means of the sandwich permeable brick mold to be interlocked with each other, thereby making the overall structure of the permeable brick more stable.

[0012] According to one embodiment of the present application, the height of the second shaping member is smaller than the height of the first shaping member.

[0013] By configuring in this way, a concave base layer and a convex surface layer can be prepared.

[0014] According to one embodiment of the present application, the second shaping member is integrally connected to the first shaping member.

[0015] Such arrangement enables the core part of the surface layer prepared by means of the sandwich permeable brick mold to be integrally connected with the surrounding part of the surface layer excluding the core part, thereby improving the overall structural strength of the sandwich permeable brick.

[0016] According to an embodiment of the present application, the second shaping member is interference fit with the outer mold, and the first shaping member and the second shaping member together form the first shaping cavity matching the base layer in the accommodating space.

[0017] With such an arrangement, only the sandwich structure is embedded in the base layer, and the other parts of the surface layer are not embedded in the base layer. Then, the base layer will not have a structure wrapping the surface layer. When the sandwich permeable brick is subjected to pressure, the force exerted on various parts of the sandwich permeable brick is more evenly distributed, thereby improving the overall structural strength of the sandwich permeable brick.

[0018] According to one embodiment of the present application, the first shaping member is in the shape of a cuboid.

[0019] With such a setting, the shape of the sandwich structure of the permeable brick prepared by means of the sandwich permeable brick mold can be a cuboid. Horizontally compared with the sandwich structure in the shape of a triangular pyramid, a triangle has stability. Although the sandwich structure in the shape of a triangular pyramid may be more stable structurally, the contact area between the cuboid-shaped sandwich structure of equal volume and the base layer is larger than that between the triangular pyramid-shaped sandwich structure of equal volume and the base layer. Therefore, the cuboid-shaped sandwich structure will make the connection between the surface layer and the base layer of the sandwich permeable brick more firm. Therefore, the cuboid-shaped sandwich structure has the advantages of both structural stability and more stable connection between the base layer and the surface layer.

[0020] According to an embodiment of the present application, the outer mold includes two L-shaped steel molds, and the two L-shaped steel molds are connected end to end to jointly enclose the accommodation space, the first opening, and the second opening.

[0021] With such a setting, the overall shape of the permeable brick prepared by means of the sandwich permeable brick mold can be a cube. Since the cube brick has a regular shape, the docking and arrangement of the cube brick are relatively simple, and it is easy to align during construction, and it is easier to meet the requirements of the building for horizontal and verticality. Therefore, using the cube brick to build a building will make the construction more convenient.

[0022] According to an embodiment of the present application, the L-shaped steel mold includes a long plate and a short plate vertically fixed at one end of the long plate.

[0023] With such a setting, the shape of the permeable brick prepared by means of the sandwich permeable brick mold can be a cuboid. Horizontally compared with the cube brick, since the size of the cube brick is fixed, it may cause more cutting and waste during use, while the length, width, and height dimensions of the cuboid brick are all different. Compared with the cube brick, the cuboid brick is more flexible in the applicable building environment. Therefore, the cuboid brick can better save materials, reduce the need for cutting bricks, and the applicable environment is also more extensive.

[0024] According to an embodiment of the present application, the outer mold further includes two connection components respectively fixed to the two L-shaped steel molds, and the connection component fixed to one L-shaped steel mold is detachably connected to the other L-shaped steel mold.

[0025] With such a setting, in the case of transporting a large number of the sandwich permeable brick molds, the outer mold can be disassembled into the L-shaped steel molds and stacked for storage, thereby saving a large amount of storage space during transportation and further reducing the transportation cost.

[0026] According to an embodiment of the present application, the connecting assembly includes a top plate connecting plate detachably connected to the top plate; a support plate fixedly connected to one end of the top plate connecting plate; a steel mold connecting plate fixedly connected to the other end of the top plate connecting plate and detachably connected to another L-shaped steel mold; and an inner mold connecting plate fixedly connected to the support plate and the steel mold connecting plate and detachably connected to the inner mold.

[0027] With such a setting, the contact area between the outer mold and the inner mold will be increased. Since the outer mold needs to bear a large force during the process of preparing the sandwich permeable brick by means of the sandwich permeable brick mold, increasing the contact area between the outer mold and the inner mold will reduce the force borne by the unit area of the contact surface between the outer mold and the inner mold. Such a setting plays a role in strengthening the outer mold to increase the service life of the outer mold.

[0028] According to an embodiment of the present application, the connecting assembly is fixed on the side of the short plate away from the accommodating space, and the support plate is integrally connected to the long plate. The top plate connecting plate, the steel mold connecting plate, and the inner mold connecting plate are all welded to the short plate of the L-shaped steel mold.

[0029] With such a setting, the material cost can be reduced. Comparing the scheme of setting the connecting assembly on the short plate with the scheme of setting the connecting assembly on the long plate, it is concluded that both schemes strengthen the outer mold. Although the strengthening effect of the latter scheme is better than that of the former scheme, the former scheme requires less material. Therefore, the scheme of setting the connecting assembly on the short plate saves materials while achieving the above-mentioned function of strengthening the outer mold, reducing the material cost.

[0030] According to an embodiment of the present application, the sandwich permeable brick mold further includes fixing bolts fixed at both ends of the bearing plate, a plurality of movable bolts movably connected to the top plate and / or the outer mold, and a plurality of movable nuts respectively matching the fixing bolts and the movable bolts; both ends of the top plate, the top plate connecting plate, the end of the long plate away from the short plate, the steel mold connecting plate, and the inner mold connecting plate are all provided with connection holes. The movable bolts pass through the connection holes of the top plate and the connection holes of the top plate connecting plate and are connected to the movable nuts. The movable bolts pass through the connection holes of the long plate and the connection holes of the steel mold connecting plate and are connected to the movable nuts. The fixing bolts pass through the connection holes of the inner mold connecting plate and are connected to the movable nuts.

[0031] With such a setting, it shows that the connection method between the outer mold, the inner mold, and the top plate is bolt connection. Compared with pin connection, the bolt connection distributes the load through uniform tension. Compared with the pin connection, the load distribution of the bolt connection is more even. Therefore, the structural stability of the bolt connection is better. And the pin connection is not suitable for frequent installation and disassembly, otherwise it will reduce the positioning accuracy and connection reliability. While the bolt connection is not only simple to disassemble and assemble, but repeated disassembly and assembly will not affect the positioning accuracy and connection reliability of the bolt connection. Using the bolt connection between the outer mold, the inner mold, and the top plate can make the overall structural stability of the sandwich permeable brick mold stronger and the service life longer.

[0043] Considering that although ordinary multi-layer permeable bricks can permeate water, the connection between their base layer and surface layer is not tight. To solve this problem, the present application provides a sandwich permeable brick mold. The permeable brick prepared by means of the sandwich permeable brick mold can have its base layer and surface layer tightly connected while permeating water.

[0044] Specifically, please refer to the attached Figures 1 to 4 , an embodiment of the present application provides a sandwich permeable brick mold 1, which may include a top plate 10, an outer mold 20, and an inner mold 30. A sandwich permeable brick with a sandwich structure can be prepared by means of the sandwich permeable brick mold 1.

[0045] More specifically, as Figures 1 to 4 shown, the sandwich permeable brick mold 1 may include an outer mold 20 having an accommodation space 201, a first opening 202 communicating with the accommodation space 201, and a second opening 203 communicating with the accommodation space 201 and arranged opposite to the first opening 202; an inner mold 30 including a bearing plate 33 detachably connected to the outer mold 20 and blocking the first opening 202, and a first shaping member 31 protruding from the bearing plate 33 and extending into the accommodation space 201. The first shaping member 31 is in clearance fit with the outer mold 20 to form a first shaping cavity 20101 in the accommodation space 201 that matches the base layer of the sandwich permeable brick; and a top plate 10 detachably connected to the outer mold 20 and blocking the second opening 203 for bearing the base layer to form a second shaping cavity 20102 in the accommodation space 201 that matches the surface layer of the sandwich permeable brick.

[0046] It should be noted that, as Figure 2 shown, by connecting the outer mold 20 and the inner mold 30, pouring the base layer material into the outer mold 20 and stamping, the base layer of the sandwich permeable brick can be prepared. Then, by connecting the outer mold 20 and the top plate 10, flipping the sandwich permeable brick mold 1, and disconnecting the outer mold 20 and the inner mold 30, in other words, removing the inner mold 30, pouring the surface layer material into the outer mold 20 and stamping, a permeable brick with a sandwich structure can be prepared. Different from the direct connection between the surface layer and the base layer of ordinary multi-layer permeable bricks, this sandwich permeable brick has a sandwich structure, and the contact area between the surface layer and the base layer is larger, so that the connection between the base layer and the surface layer of this sandwich permeable brick is tighter.

[0047] It should be noted that, as Figure 3As shown, the inner mold 30 further includes a second shaping member 32 protruding from the bearing plate 33 and extending into the accommodation space 201. The second shaping member 32 surrounds the first shaping member 31, and the height of the second shaping member 32 is different from the height of the first shaping member 31. In other words, the top surface of the second shaping member 32 and the top surface of the first shaping member 31 are not on the same plane. The second shaping member 32 and the first shaping member 31 together form a stepped structure, and the stepped structure includes but is not limited to an outer stepped structure and an inner stepped structure. This can enable the surface layer and the base layer of the sandwich permeable brick prepared by means of the sandwich permeable brick mold 1 to be mutually interlocked, thereby making the overall structure of the permeable brick more stable.

[0048] Optionally, as Figure 2 shown, the height of the second shaping member 32 is less than the height of the first shaping member 31. In other words, the second shaping member 32 and the first shaping member 31 together form an outer stepped structure. This can prepare a concave base layer and a convex surface layer. In another embodiment of the present application, the height of the second shaping member 32 is greater than the height of the first shaping member 31. In other words, the second shaping member 32 and the first shaping member 31 together form an inner stepped structure, and the above structure will prepare a convex base layer and a concave surface layer.

[0049] It should be noted that, as Figure 2 shown, the second shaping member 32 is integrally connected to the first shaping member 31, that is, there is no gap at the connection between the second shaping member 32 and the first shaping member 31, so that the sandwich part of the surface layer of the sandwich permeable brick prepared by means of the sandwich permeable brick mold 1 is integrally connected to the surrounding part of the surface layer except the sandwich part. In other words, the surface layer is seamless as a whole, so that the overall structural strength of the sandwich permeable brick is relatively high.

[0050] It should be noted that, as Figure 1 and Figure 4 shown, the second shaping member 32 is in interference fit with the outer mold 20. The first shaping member 31 and the second shaping member 32 together form the first shaping cavity 20101 in the accommodation space 201 that matches the base layer. In this way, in the sandwich permeable brick prepared by means of the sandwich permeable brick mold 1, only the sandwich part of the surface layer is embedded in the base layer. In other words, except for the sandwich part, the surface layer is not embedded in the base layer, so that the base layer will not have a structure that wraps the surface layer. When the edge of the sandwich permeable brick is subjected to pressure, the above structure will distribute the pressure more evenly to each part of the sandwich permeable brick, so that the overall compressive strength of the sandwich permeable brick is relatively high.

[0051] It should be noted that, as Figure 2As shown, the shape of the first shaping member 31 is a cuboid, so that the shape of the sandwich structure of the permeable brick prepared by means of the sandwich permeable brick mold 1 is cuboid. Horizontally, compared with the triangular pyramid-shaped sandwich structure, the triangle has stability. Therefore, this triangular pyramid-shaped sandwich structure is more stable in structure. However, because the contact area between the cuboid-shaped sandwich structure of equal volume and the base layer is larger than the contact area between this triangular pyramid-shaped sandwich structure of equal volume and the base layer, the connection between the surface layer and the base layer of this sandwich permeable brick will be more firm when the sandwich structure is cuboid. Therefore, using the first shaping member 31 with the shape of a cuboid will make this sandwich permeable brick have the advantages of both stable structure and more firm connection between the base layer and the surface layer.

[0052] It should be noted that, as Figures 1 to 4 shown, the outer mold 20 includes two L-shaped steel molds 21, and the two L-shaped steel molds 21 are connected end to end to jointly enclose the accommodation space 201, the first opening 202 and the second opening 203. In this way, the overall structure of the permeable brick prepared by means of the sandwich permeable brick mold 1 will be a cube. Since the shape of the cube brick is regular, it is relatively simple to arrange and join the cube bricks. During construction, it is easier to align and can better meet the requirements of the building for horizontal and verticality. Therefore, using this cube brick to build a building will make the construction more convenient.

[0053] In particular, as Figure 3 and Figure 4 shown, the L-shaped steel mold 21 includes: a long plate 211 and a short plate 212 vertically fixed at one end of the long plate 211. Therefore, the overall structure of the permeable brick prepared by means of the sandwich permeable brick mold 1 is a cuboid. Horizontally, compared with the cube brick, because the size of the cube brick is fixed, in order to achieve different building goals during use, more cutting may be done to the cube brick, which will waste materials. While the length, width and height dimensions of the cuboid brick are all different. Compared with the cube brick, the cuboid brick is more flexible in the applicable building environment. Therefore, the cuboid brick can better save materials, reduce costs and the applicable environment is also more extensive.

[0054] It should be noted that, as Figure 3 and Figure 4As shown, the outer mold 20 further includes two connecting components 22 respectively fixed to the two L-shaped steel molds 21. The connecting component 22 fixed to one of the L-shaped steel molds 21 is detachably connected to the other L-shaped steel mold 21. In this way, when it is necessary to store the sandwich permeable brick mold 1, the outer mold 20 with the largest volume in the sandwich permeable brick mold 1 can be disassembled and stacked. Since the outer mold 20 includes the hollow accommodation space 201, disassembling and stacking the outer mold 20 can reduce the storage space of the outer mold 20, thereby reducing the storage cost of the sandwich permeable brick mold 1.

[0055] It should be noted that, as Figure 1 , Figure 3 and Figure 4 shown, the connecting component 22 includes a top plate connecting plate 221 detachably connected to the top plate 10; a support plate 222 fixedly connected to one end of the top plate connecting plate 221; a steel mold connecting plate 224 fixedly connected to the other end of the top plate connecting plate 221 and detachably connected to the other L-shaped steel mold 21; and an inner mold connecting plate 223 fixedly connected to the support plate 222 and the steel mold connecting plate 224 and detachably connected to the inner mold 30. This can increase the contact area between the outer mold 20 and the inner mold 30. During the process of preparing the sandwich permeable brick by means of the sandwich permeable brick mold 1, the outer mold 20 needs to bear a large pressure. Increasing the contact area between the outer mold 20 and the inner mold 30 will reduce the force borne by the unit area of the contact surface between the outer mold 20 and the inner mold 30. This can play a role in increasing the structural strength of the outer mold 20 to increase the service life of the outer mold 20.

[0056] Particularly, as Figure 3 and Figure 4As shown, the connecting component 22 is fixedly arranged on the side of the short plate 212 away from the accommodating space 201, and the support plate 222 and the long plate 211 are integrally connected. The top plate connecting plate 221, the steel mold connecting plate 224 and the inner mold connecting plate 223 are all welded to the short plate 212 of the L-shaped steel mold 21. In this way, compared with the scheme of fixedly arranging the connecting component 22 on the long plate 211, because the long plate 211 and the short plate 212 are vertically connected, the lengths of the support plate 222 and the steel mold connecting plate 224 in the two schemes are equal. However, the length of the long plate 211 is longer than that of the short plate 212. Therefore, the lengths of the top plate connecting plate 221 and the inner mold connecting plate 223 in the scheme of arranging the connecting component 22 on the short plate 212 are shorter than those of the top plate connecting plate 221 and the inner mold connecting plate 223 in the other scheme. Therefore, the scheme of fixedly arranging the connecting component 22 on the short plate 212 saves materials on the premise of achieving the above purpose of strengthening the outer mold 20, thereby reducing the material cost.

[0057] It should be noted that as Figure 1 and Figure 3As shown, the sandwich permeable brick mold 1 further includes fixing bolts 40 fixed at both ends of the bearing plate 33, a plurality of movable bolts 50 movably connected to the top plate 10 and / or the outer mold 20, and a plurality of movable nuts 60 respectively matching the fixing bolts 40 and the movable bolts 50; both ends of the top plate 10, the top plate connecting plate 221, the long plate 211 away from one end of the short plate 212, the steel mold connecting plate 224, and the inner mold connecting plate 223 are all provided with connection holes 70. The movable bolt 50 passes through the connection hole 70 of the top plate 10 and the connection hole 70 of the top plate connecting plate 221 and is connected to the movable nut 60, so as to connect the top plate 10 and the outer mold 20. The movable bolt 50 passes through the connection hole 70 of the long plate 211 and the connection hole 70 of the steel mold connecting plate 224 and is connected to the movable nut 60, so as to connect the two L-shaped steel molds 21. The fixing bolt 40 passes through the connection hole 70 of the inner mold connecting plate 223 and is connected to the movable nut 60, so as to connect the outer mold 20 and the inner mold 30. It can be obtained that the connection method between the outer mold 20, the inner mold 30, and the top plate 10 is bolt connection. Compared with pin connection, the bolt connection distributes the load through uniform tension. Compared with the pin connection, the load distribution of the bolt connection is more even. Therefore, the structural stability of the bolt connection is better. And the pin connection is not suitable for frequent installation and disassembly, otherwise it will reduce the positioning accuracy and connection reliability. While the bolt connection is not only simple to disassemble and assemble, but repeated disassembly and assembly will not affect the positioning accuracy and connection reliability of the bolt connection. Using the bolt connection between the outer mold 20, the inner mold 30, and the top plate 10 can make the overall structural stability of the sandwich permeable brick mold 1 stronger and the service life longer.

[0058] Without changing the basic principle of the present invention, the technical features of the above embodiments can be combined. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not conflict, it should be considered as the scope described in this specification.

[0059] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
