Technical Field

[0001] This utility model patent relates to the field of concrete building material processing, specifically a mold for processing and pouring concrete hollow bricks. Background Art

[0002] Currently, in actual construction production, there are problems such as the heavy weight of wall bricks, inconvenience in handling, and high manufacturing costs. With the continuous progress and development of society, as well as the increasing awareness of environmental protection and energy conservation, the development of the energy-saving building field is also very rapid. The use of lightweight, hollow wall bricks is increasing. Compared with solid wall bricks, they can save a lot of land and brick-making fuel, reduce transportation weight, reduce labor intensity during brick making and masonry, speed up construction progress, reduce building weight, increase the number of building floors, reduce costs, and maximize the utilization of resources and energy.

[0003] Most current hollow brick casting molds are as shown in the Chinese patent "Mold for Producing Hollow Bricks" (patent number CN202120215457.X, publication date 20211130). This patent document describes the following structure: a mold for producing hollow bricks includes a rectangular cavity for casting the brick body, an upper cover plate and a lower cover plate for creating holes. The inner sides of the left and right side plates of the rectangular cavity are respectively provided with protruding ridges and slots. The inner side of the upper cover plate is provided with a groove and a row of inverted conical columns. The inner side of the lower cover plate is provided with a boss and a row of conical columns, with the conical columns interlaced between the inverted conical columns. This invention's mold allows the prepared hollow bricks to have a high porosity, making assembly easier. The prepared hollow bricks can be spliced ​​on all four sides (up, down, left, and right) to satisfy the need for extension in both width and height directions. Simultaneously, by setting staggered and inverted through holes on the brick body, the porosity of the brick body is increased.

[0004] The mold described in the above-mentioned prior art solves the problems of casting and forming hollow bricks and improving the porosity of the brick body very well. However, this casting mold has the following defects during use: the size of the internal space of the mold is determined during processing, and when processing bricks of different sizes, the mold needs to be redesigned, and the versatility is not high. Utility Model Content

[0005] The utility model is intended to provide a mold for processing and pouring concrete hollow bricks, which is mainly used to solve the technical problems in the prior art that the size of the internal space of the mold is determined during processing, and the mold needs to be redesigned when processing bricks of different sizes, and the mold is not very versatile.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A mold for processing and pouring concrete hollow bricks includes several detachably connected unit molds. The unit mold includes a box body. Several partitions are detachably connected to the inside of the box body. The several partitions divide the space inside the box body into several accommodating cavities. Several support assemblies for making hollow brick cavities are detachably connected to the inside of the accommodating cavities.

[0008] The working principle and beneficial effects of this utility model:

[0009] 1. Working principle: When casting hollow concrete bricks, the unit molds are first assembled. Specifically, the partition is installed inside the box, dividing the internal space of the box into several cavities. The support components are then installed inside the cavities. After the assembly is completed, the unit molds are connected together. Then, release oil is sprayed throughout the entire internal space of the mold. The concrete slurry used for casting hollow bricks is then poured into the several cavities inside the box. After a series of processing steps, the slurry solidifies. The solidified bricks are then demolded, and the bricks are then steam-cured or fired to solidify.

[0010] 2.Beneficial effects:

[0011] (1) This solution divides the space inside the box into several cavities by installing a removable partition inside the box. The size of the cavities can be adjusted by adjusting the position of the partition, thereby processing hollow bricks of different sizes. Compared with existing molds, this mold is more versatile and meets the needs of producing bricks of different sizes. It solves the technical problem that the size of the internal space of the mold is determined during processing, and the mold needs to be redesigned when processing bricks of different sizes, resulting in low versatility of the mold.

[0012] (2) This mold is assembled from multiple unit molds. When a large number of hollow bricks need to be produced, it is only necessary to connect the corresponding number of unit molds together and then cast them at one time.

[0013] Preferably, the box body comprises a bottom plate and a rectangular ring-shaped box body, wherein the box body is nested outside the bottom plate, and the inner wall of the box body contacts the outer side surface of the bottom plate. When assembling the box body, it is sufficient to nest the box body on the bottom plate. When demolding the brick body, it is sufficient to press the brick body and then lift the box body to separate the box body from the bottom plate and the brick surface.

[0014] Preferably, the upper surface of the bottom plate is provided with a plurality of grooves. The bottom plate is provided with grooves, so that the bottom of the poured brick body is also formed with grooves. This brick body shape can better combine with the concrete used for wall construction during use, thereby increasing the strength of the wall.

[0015] Preferably, the lower end of the partition is machined with a first protrusion that matches the groove, and the side walls of the partition are against the inner wall of the box body. The first protrusion is inserted into the groove of the bottom plate, and the two ends are against the box body. The groove and the box body together limit the partition, so that the partition is firmly engaged in the interior of the box body, dividing the internal space of the box body.

[0016] Preferably, the support assembly includes a crossbar, the lower surfaces of both ends of the crossbar contacting the upper surface of the box body, and a support column is vertically fixed to the bottom of the crossbar. A second protrusion that mates with a groove is provided at the end of the support column away from the crossbar. The two ends of the crossbar rest on the upper surface of the box body, and the second protrusion at the bottom of the support column can be inserted into the groove. The groove and the crossbar together keep the support column upright within the receiving cavity. When the brick body is poured and demolded, the operator can simply pull the support column out from inside the brick body by holding both ends of the crossbar.

[0017] Preferably, baffles are provided on the upper surface of the box body at both ends of the crossbars, the baffles being in contact with the ends of the crossbars. The baffles are provided so that when pillar assemblies of the same specification are inserted into the box body, the ends of the crossbars are restrained by the baffles, so that all the crossbars are arranged in parallel, and thus all the pillars are also arranged in parallel, thereby maintaining uniform pore sizes within hollow bricks of uniform size.

[0018] Preferably, two threaded rods are fixed at both ends of the box body. Adjacent threaded rods on adjacent box bodies are fitted with connecting plates, and the ends of the threaded rods furthest from the box body are threaded with nuts to prevent the connecting plates from disengaging from the threaded rods. The purpose of the connecting plates is to connect adjacent box bodies together and to limit the connecting plates with nuts, preventing them from disengaging from the threaded rods. Additionally, when demolding the box body, the threaded rods at both ends can also act as handles, allowing operators to easily lift the box body by holding the threaded rods.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-4 As shown, a mold for processing and casting hollow concrete bricks includes several detachably connected unit molds. Each unit mold includes a box body, which includes a bottom plate 2 and a box body 1. The bottom surface of the bottom plate 2 is rectangular, and the overall shape is close to a cube. The top surface of the bottom plate 2 has several neatly arranged grooves 21, which are dovetail-shaped grooves 21. The box body 1 is rectangular and is nested on the outside of the bottom plate 2, with the inner wall of the box body 1 in contact with the outer side of the bottom plate 2. When assembling the box body, it is only necessary to nest the box body 1 on the bottom plate 2. When demolding the brick, it is only necessary to hold the brick and then lift the box body 1 to separate the box body 1 from the bottom plate 2 and the surface of the brick.

[0026] like Figure 4 As shown, two threaded rods 12 are fixed to each end of the box body 1. Adjacent threaded rods 12 on adjacent box bodies 1 are commonly mounted with connecting plates 6. The ends of the threaded rods 12 facing away from the box bodies are threadedly connected to nuts 6 that are used to prevent the connecting plates 6 from coming off the screws. The connecting plates 6 are provided to connect adjacent box bodies together, and the nuts 6 are used to limit the connecting plates 6 from coming off the threaded rods 12. Furthermore, when the box body 1 needs to be demolded, the threaded rods 12 at both ends of the box body 1 also serve as handles, making it easier for the operator to lift the box body 1 by holding the threaded rods 12.

[0027] Several partitions 4 are detachably connected to the interior of the box body. The lower ends of the partitions 4 are processed with first protrusions 41 that match the grooves 21. The first protrusions 41 are wedge-shaped to match the grooves 21. The side walls of the partitions 4 at both ends abut against the inner wall of the box body 1. The partitions 4 are inserted into the box body 1. The partitions 4 divide the space inside the box body into several accommodating chambers.

[0028] like Figure 2 , Figure 3As shown, the cavity contains several detachable support pillars 32 assemblies for creating the hollow brick cavities. Each support pillar 32 assembly includes a crossbar 31, with its lower surfaces at both ends contacting the upper surface of the box body 1. A support pillar 32 is vertically fixed to the bottom of the crossbar 31. The end of the support pillar 32 away from the crossbar 31 has a second protrusion 321 that mates with a groove 21. A first protrusion 41, matching the groove 21, is also wedge-shaped. Both ends of the crossbar 31 rest on the upper surface of the box body 1, and the second protrusion 321 at the bottom of the support pillar 32 can be inserted into the groove 21. The groove 21 and the crossbar 31 together keep the support pillar 32 upright within the cavity. When the brick is poured and demolded, the operator can simply pull the support pillar 32 out of the brick by holding both ends of the crossbar 31.

[0029] like Figure 2 , Figure 3 As shown, baffles 11 are provided on the upper surface of the box body 1 at both ends of the crossbars 31, and the baffles 11 contact the ends of the crossbars 31. The baffles 11 ensure that when pillars 32 of the same specification are inserted into the box body, the ends of the crossbars 31 are restrained by the baffles 11, so that all crossbars 31 are arranged in parallel, and thus all pillars 32 are also arranged in parallel, thereby maintaining the uniform size of the pores in the hollow bricks of the same size.

[0030] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0031] When pouring hollow concrete bricks, the box body is first assembled, and then the partition 4 is installed inside the box body to divide the internal space of the box body into several receiving cavities. The support column 32 assembly is then installed in the receiving cavity. Specifically, the second protrusion 321 at the lower end of the support column 32 is directly inserted into the designated groove 21, and then the two ends of the crossbar 31 are pressed against the side of the baffle 11. Next, the adjacent boxes are connected together through the connecting plate 6, and then the connecting plate 6 is fixed with the nut 6.

[0032] After installation, release oil is sprayed throughout the entire interior space of the mold. Then, concrete slurry for casting hollow bricks is poured into several cavities inside the box. After a series of processing steps, once the slurry has solidified, the operator disassembles the connecting plate 6, separates the adjacent boxes, and then uses the threaded rod 12 to separate the box body 1 from the brick body. The solidified brick body is then demolded, and the brick body is then steam-cured or fired to solidify.

[0033] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
