Description

Technical Field

[0001] The present application belongs to the technical field of pavement building materials, and specifically relates to a method for preparing a building block concrete block, the prepared building block concrete and applications thereof. Background Art

[0002] Due to the excellent performance of concrete, it is still a type of pavement material that is widely used. As artistic concrete among concrete, it is widely used in many application scenarios due to its designability. However, with the improvement of people's aesthetic taste, the requirements for the color matching and pattern of artistic pavements are also getting higher and higher. For example, the pavement pattern is required to be mixed and matched, which increases the difficulty of construction and the construction period is usually very long. At present, a commonly used alternative method is to use organic system pavement materials that are easy to construct and also have designability. However, this alternative method will sacrifice the excellent physical properties of concrete materials and limit the application scenarios.

[0003] At present, due to the excellent performance of concrete, it cannot be completely replaced by other road materials for the time being, so the problem of the difficulty of artistic road construction must be solved. In the Chinese patent application with publication number CN107935503A, a concrete slab is disclosed, which is a prefabricated small block of colored concrete with different shapes. The concrete slab is used to construct an artistic floor, which is easier to construct while meeting aesthetic requirements. The production method of the concrete slab is as follows: pouring colored concrete into a mother mold and obtaining the concrete slab after demolding. Although the use of concrete slabs to construct artistic floors can reduce the construction difficulty of artistic floors, the number of concrete slabs required for each construction is large, and the concrete slabs need to be demolded one by one. There are still shortcomings such as large workload and low efficiency in the production stage of concrete slabs. Summary of the invention

[0042] The specific implementation methods of the present application and the technical effects produced will be described clearly and completely below in combination with the embodiments and drawings, so as to fully understand the purpose, features and effects of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments of the present application, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present application.

[0043] Example 1

[0044] The method for preparing the building block concrete block provided in this embodiment has the following specific steps:

[0045] The first step is to lay a tarpaulin on the ground and place a fence on the tarpaulin to form a pouring space with the tarpaulin as the bottom and the fence as the side wall; the height of the fence is preferably 0.5 cm-1.5 cm, and the pouring space formed is a rectangular space with a height of 0.5 cm-1.5 cm;

[0046] In the specific implementation, choose a flat ground to lay the tarpaulin, and use stainless steel angle steel as the enclosure. The stainless steel angle steel has high hardness and corrosion resistance, which can ensure that it is not easy to deform in the subsequent stamping process. In order to prevent the tarpaulin from moving or wrinkling during the pouring process, you can use a heavy object to press the angle steel to fix the tarpaulin; you can also choose a single-sided angle steel with holes, place the perforated edge on the tarpaulin, and use nails and other fasteners to pass through the holes on the angle steel to fix the tarpaulin.

[0047] The second step is to pour concrete slurry into the pouring space; in this embodiment, the concrete slurry is colored concrete slurry; the raw materials of colored concrete slurry mostly include cement, quartz sand aggregate, silica fume, admixtures, pigments, etc.

[0048] The third step is to use an imprinting mold to imprint the concrete in the pouring space when the concrete is initially set, so that the protruding pattern on the imprinting surface is pressed into the concrete, and the imprinted pattern appears on the concrete;

[0049] To ensure that the concrete is smoothly split along the embossed lines in the fourth step, the protrusion height of the lines on the embossed surface should reach 1 / 2-2 / 3 of the height of the pouring space. In this embodiment, the embossing mold is made of plastic, the outer contour of the embossed surface is square or rectangular, the side length is 30cm-120cm, the embossed surface thickness is 0.5cm-0.8cm, the protrusion height of the lines on the embossed surface is 0.25cm-0.75cm, and the width of the lines is 0.2cm-0.3cm.

[0050] In the present application, the texture pattern is a grid pattern formed by the first linear protrusions 1 arranged horizontally and the second linear protrusions 2 arranged vertically or obliquely. In order to obtain more shapes of building blocks, each basic pattern of the texture pattern further includes a third protrusion 3, which can be a straight line, a curve or a broken line protrusion, and the third protrusion 3 is used to separate the basic pattern into at least two areas.

[0051] See also Figure 1-4 , showing 4 different texture patterns, the red lines in the figure represent protrusions. Figure 1 The third protrusion is a curved protrusion, which divides the basic pattern into two irregularly shaped areas. Figure 1 The texture pattern can obtain shape 1 and shape 2 building block concrete blocks. Figure 2 The third protrusion is a straight line, which divides the basic pattern into two right-angled triangle areas. Figure 2 The texture pattern can obtain a shape 3 building block concrete block. Figure 3 The third protrusion is also a straight line, which divides the basic pattern into a right-angled triangle area and a right-angled trapezoid area. Figure 3 The texture pattern can obtain shape 4 and shape 5 building block concrete blocks. Figure 4 There are multiple third protrusions in the pattern, which divide the basic pattern into 5 areas. Figure 4 The texture pattern can obtain building block concrete blocks of shape 6, shape 7 and shape 8.

[0052] In the present application, the first linear protrusion 1, the second linear protrusion 2 and the third protrusion 3 are all used to form an impression on the concrete to facilitate the splitting of the building concrete block. Therefore, the protrusion height of the first linear protrusion 1, the second linear protrusion 2 and the third protrusion 3 should reach 1 / 2-2 / 3 of the height of the casting space.

[0053] The fourth step is to wait for the concrete to completely solidify, remove the enclosure, and use an elastic striking tool to strike the concrete to split the concrete pressing pattern to obtain a building block concrete block. In this embodiment, the elastic striking tool is a rubber hammer.

[0054] In the present application, the raised pattern on the stamping mold is used to separate the concrete. After stamping is completed, the stamping pattern on the concrete divides the concrete into many small blocks, which are identical or partially identical in shape. After the concrete is completely solidified, the concrete is split by pressing the stamping pattern through external force to obtain building block concrete blocks.

[0055] Example 2

[0056] This embodiment provides an application of the building block concrete block prepared in Example 1, which includes using the building block concrete block to construct an artistic pavement, and the specific steps are as follows:

[0057] (2) Lay the design drawing of the artistic floor pattern on the ground, and lay a layer of mesh cloth on the design drawing; the pattern in the artistic floor design drawing in this embodiment is a plum blossom, see Figure 5 As shown;

[0058] (2) According to the colors and shapes in the design drawings, stick the corresponding colored concrete blocks on the mesh cloth, and then spray the sealant;

[0059] (3) The mesh cloth is transferred to the initially set concrete pavement, and the building blocks of concrete are knocked into the concrete pavement using an elastic knocking tool so that the building blocks of concrete are completely embedded in the concrete;

[0060] (4) Use the same concrete slurry to fill the gaps between the building blocks and cover the building blocks, then level them, and then spray a retarder on the building blocks; the same concrete slurry is the same as the pavement concrete;

[0061] (5) flushing the concrete block area to expose the surface of the concrete block; this step is performed when the concrete pavement is solidified but the concrete covering the concrete block area is initially solidified;

[0062] (6) After the concrete pavement is completely solidified, spray the sealant on the surface of the concrete pavement. Figure 6-7 As shown, Figure 6 Aerial photo of plum blossom shape. Figure 7 This is a close-up photo, and you can see that the plum blossom shape is constructed from building blocks of concrete.

[0063] Example 3

[0064] This embodiment will provide an application of the building block concrete blocks prepared in Example 1, which also includes using the building block concrete blocks to construct an artistic pavement, but the specific steps are different, as follows:

[0065] (1) Lay the design drawings of the artistic floor pattern on the ground, and lay a layer of mesh cloth on the design drawings;

[0066] (2) According to the colors and shapes in the design drawings, stick the corresponding colored concrete blocks on the mesh cloth, and then spray the sealant;

[0067] (3) The mesh cloth is transferred to the initially set concrete pavement, and the building blocks of concrete are knocked into the concrete pavement using an elastic knocking tool so that the building blocks of concrete are completely embedded in the concrete;

[0068] (4) Use the same concrete slurry to fill the gaps between the building blocks and cover the building blocks, and then level them; the same concrete slurry is the same as the pavement concrete;

[0069] (5) After the concrete in the building block concrete block area is completely solidified, the building block concrete block area is ground and polished to expose the building block concrete blocks.

[0070] It should be noted that the building block concrete blocks prepared by the method of the present application have rough splitting parts and retain irregular protrusions. In this way, when the building block concrete blocks are used to construct artistic pavements, the building block concrete blocks will be more tightly combined with the pavement concrete to avoid falling off.

[0071] The above is a specific description of the preferred implementation of the present application, but the invention of the present application is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the invention. These equivalent deformations or substitutions are all included in the scope defined by the claims of the present application.
