Description

Technical Field

[0001] This application belongs to the field of road construction materials technology, specifically relating to a method for preparing building block concrete blocks, the prepared building block concrete, and its application. Background Technology

[0002] Due to its excellent properties, concrete remains a widely used road surface material. As a type of concrete, artistic concrete is widely used in many applications due to its designability. However, with the improvement of people's aesthetic sense, the requirements for the color schemes and patterns of artistic pavements are also constantly increasing, such as requiring mixed color schemes, which leads to increased construction difficulty and a typically long construction period. Currently, a common alternative is to use organic pavement materials that are easy to construct and also offer designability. However, this alternative sacrifices the excellent physical properties of concrete, limiting its application scenarios.

[0003] Currently, due to the superior properties of concrete, it cannot be completely replaced by other road surface materials, so the difficulty of constructing artistic pavements must be addressed. Chinese patent application CN107935503A discloses a type of precast concrete slab, which consists of small, colored concrete blocks of various shapes. Using concrete slabs to construct artistic floors satisfies aesthetic requirements while also being easier to construct. The production method involves pouring colored concrete into a master mold and then demolding to obtain the concrete slabs. While using concrete slabs to construct artistic floors reduces the difficulty of construction, a large number of slabs are required for each construction project, and each slab needs to be demolded individually. Therefore, the production stage of concrete slabs still suffers from high workload and low efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a method for preparing building block concrete blocks, the prepared building block concrete, and its application. The preparation of building block concrete blocks in this application does not involve a demolding process, and the production efficiency of building block concrete blocks is significantly improved.

[0005] Firstly, this application provides a method for preparing building block concrete blocks, comprising the following steps:

[0006] The first step is to lay the waterproof tarpaulin on the ground and place the enclosure on the tarpaulin to form a pouring space with the tarpaulin as the bottom and the enclosure as the side walls.

[0007] The second step is to pour the concrete grout into the pouring space;

[0008] The third step involves using an impression mold to imprint the concrete within the pouring space during the initial setting of the concrete. This process presses the raised patterns on the impression surface into the concrete, creating an impression pattern on the concrete. The height of the raised patterns is 1 / 2 to 2 / 3 of the height of the pouring space. The pattern is a grid pattern formed by the intersection of horizontally arranged first linear protrusions and vertically or obliquely arranged second linear protrusions.

[0009] Fourth step: After the concrete has completely hardened, remove the barriers and use a flexible hammering tool to tap the concrete to break the indentation, thus obtaining the building block concrete blocks.

[0010] Furthermore, the height of the enclosure is 0.5cm-1.5cm.

[0011] Furthermore, angle steel was chosen for the fencing.

[0012] Furthermore, the concrete grout is a colored concrete grout.

[0013] Furthermore, the height of the raised pattern is 0.25cm-0.75cm, and the width of the pattern is 0.2cm-0.3cm.

[0014] Furthermore, each basic pattern of the texture pattern further includes a third protrusion, which is used to divide the basic pattern into at least two regions.

[0015] Furthermore, the third protrusion can be a straight line, a curved line, or a broken line.

[0016] Secondly, the concrete block provided in this application is a concrete block prepared using the above-described preparation method.

[0017] Thirdly, one application of the building block concrete block prepared by the above-described preparation method provided in this application includes:

[0018] Lay the design drawings of the artistic floor pattern on the ground, and then lay a layer of mesh fabric on top of the design drawings;

[0019] (2) According to the colors and shapes in the design drawings, paste the corresponding colored concrete blocks onto the mesh cloth, and then spray sealant;

[0020] (3) Transfer the mesh to the initially set concrete pavement and use an elastic hammering tool to hammer the concrete blocks into the concrete pavement;

[0021] (4) Fill the gaps between the building blocks with the same concrete slurry and cover the building blocks, then level it, and then spray a retarder on the area of ​​the building blocks; the same concrete slurry is the same as the road concrete.

[0022] (5) Rinse the concrete block area to expose the concrete block surface;

[0023] (6) After the concrete pavement has completely solidified, spray a sealant onto the concrete pavement surface.

[0024] Fourthly, another application of the building block concrete blocks prepared by the above-described preparation method provided in this application includes:

[0025] Lay the design drawings of the artistic floor pattern on the ground, and then lay a layer of mesh fabric on top of the design drawings;

[0026] (2) According to the colors and shapes in the design drawings, paste the corresponding colored concrete blocks onto the mesh cloth, and then spray sealant;

[0027] (3) Transfer the mesh to the initially set concrete pavement and use an elastic hammering tool to hammer the concrete blocks into the concrete pavement;

[0028] (4) Fill the gaps between the concrete blocks with the same concrete grout and cover the concrete blocks, then level it; the same concrete grout is the same as the road surface concrete;

[0029] (5) Once the concrete in the block area has completely solidified, grind and polish the block area to expose the block.

[0030] This application has the following characteristics and beneficial effects:

[0031] 1. Compared with the current method of using molds to prepare building block concrete blocks, the method of preparing building block concrete blocks in this application eliminates the cumbersome demolding process, and the production efficiency is significantly improved;

[0032] 2. This application can design a strong shape, and by designing the embossing pattern, it is convenient to prepare concrete blocks with various shapes and forms;

[0042] The specific implementation methods and technical effects of this application will be clearly and completely described below with reference to the embodiments and accompanying drawings, so as to fully understand the purpose, features and effects of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application. Example

[0043] The method for preparing the building block concrete blocks provided in this embodiment includes the following specific steps:

[0044] The first step is to lay a waterproof tarpaulin on the ground and place a barrier on the tarpaulin to form a pouring space with the tarpaulin as the bottom and the barrier as the side walls; the height of the barrier is preferably 0.5cm-1.5cm, and the resulting pouring space is a rectangular space with a height of 0.5cm-1.5cm.

[0045] In practice, a flat surface is selected to lay the waterproof tarpaulin. Stainless steel angle steel is used as a barrier. The stainless steel angle steel has high hardness and rust resistance, which can ensure that it is not easily deformed during the subsequent stamping process. To prevent the waterproof tarpaulin from moving or wrinkling during the pouring process, heavy objects can be used to weigh down the angle steel to fix the tarpaulin; alternatively, angle steel with holes on one side can be selected, and the perforated side can be placed on the waterproof tarpaulin. Fasteners such as nails can be passed through the holes in the angle steel to fix the waterproof tarpaulin.

[0046] The second step is to pour the 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.

[0047] 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 raised patterns on the imprinting surface are pressed into the concrete, and imprinted patterns appear on the concrete.

[0048] To ensure smooth concrete splitting along the embossed patterns in step four, the protrusion height of the pattern on the embossed surface should reach 1 / 2 to 2 / 3 of the pouring space height. In this embodiment, the embossing mold is made of plastic, with a square or rectangular outer contour of the embossed surface, a side length of 30cm-120cm, an embossed surface thickness of 0.5cm-0.8cm, a protrusion height of the pattern on the embossed surface of 0.25cm-0.75cm, and a pattern width of 0.2cm-0.3cm.

[0049] In this application, the texture pattern is a grid pattern formed by the intersection of horizontally arranged first linear protrusions 1 and vertically or obliquely arranged second linear protrusions 2. In order to obtain more shapes of building block concrete 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 is used to divide the basic pattern into at least two regions.

[0050] Please see Figure 1-4 The image shows four different texture patterns, with red lines representing protrusions. Figure 1 The third protrusion is a curved protrusion, which divides the basic pattern into two irregularly shaped regions. Figure 1 The texture pattern can be used to obtain building block concrete blocks of shape 1 and shape 2. Figure 2 The third protrusion in the middle is linear, dividing the basic pattern into two right-angled triangular regions. Figure 2 The texture pattern can be used to obtain shape 3 concrete blocks. Figure 3 The third protrusion is also linear, dividing the basic pattern into right-angled triangular and right-angled trapezoidal regions. Figure 3 The texture pattern can be used to obtain building block concrete blocks of shapes 4 and 5. Figure 4 There are multiple third protrusions that divide the basic pattern into 5 regions, using... Figure 4 The texture patterns can be used to obtain concrete blocks of shapes 6, 7, and 8.

[0051] In this application, the first linear protrusion 1, the second linear protrusion 2, and the third protrusion 3 are all used to form an imprint on the concrete to facilitate the splitting of the concrete blocks. Therefore, the protrusion height of the first linear protrusion 1, the second linear protrusion 2, and the third protrusion 3 should all reach 1 / 2 to 2 / 3 of the pouring space height.

[0052] Fourth, after the concrete has completely hardened, remove the barriers and use a flexible hammering tool to tap the concrete, causing the indentation to crack and form building block-like concrete blocks. In this embodiment, a rubber hammer is selected as the flexible hammering tool.

[0053] In this application, the raised patterns on the stamping mold are used to divide the concrete. After stamping, the stamped patterns on the concrete divide it into many small blocks, which are the same or partially the same shape. After the concrete has completely solidified, external force is applied to cause the concrete to split along the stamped patterns, resulting in building block concrete blocks. Example

[0054] This embodiment will provide an application of the building block concrete blocks prepared in Embodiment 1. This application includes using the building block concrete blocks to construct artistic pavements, and the specific steps are as follows:

[0055] (1) The design drawings for the artistic floor pattern are laid on the ground, and a layer of mesh fabric is laid on the design drawings; in this embodiment, the pattern in the artistic floor design drawings is a plum blossom, see Figure 5 As shown;

[0056] (2) According to the colors and shapes in the design drawings, paste the corresponding colored concrete blocks onto the mesh cloth, and then spray sealant;

[0057] (3) Transfer the mesh cloth to the initially set concrete pavement and use an elastic hammering tool to hammer the building block concrete blocks into the concrete pavement so that the building block concrete blocks are completely embedded in the concrete.

[0058] (4) Fill the gaps between the building blocks with the same concrete slurry and cover the building blocks, then level it, and then spray a retarder on the area of ​​the building blocks; the same concrete slurry is the same as the road concrete.

[0059] (5) Rinse the concrete block area to expose the concrete block surface; this step is performed when the concrete pavement has hardened but the concrete covering the concrete block area has initially set.

[0060] (6) After the concrete pavement has completely hardened, spray a sealant onto the surface of the concrete pavement. See the finished product for reference. Figure 6-7 As shown, where, Figure 6 Aerial photo shaped like a plum blossom. Figure 7 The close-up photo shows that the plum blossom shape is constructed from building blocks of concrete. Example

[0061] This embodiment will provide an application of the building block concrete blocks prepared in Embodiment 1. This application also includes using building block concrete blocks to construct artistic pavements, but the specific steps are different, as follows:

[0062] Lay the design drawings of the artistic floor pattern on the ground, and then lay a layer of mesh fabric on top of the design drawings;

[0063] (2) According to the colors and shapes in the design drawings, paste the corresponding colored concrete blocks onto the mesh cloth, and then spray sealant;

[0064] (3) Transfer the mesh cloth to the initially set concrete pavement and use an elastic hammering tool to hammer the building block concrete blocks into the concrete pavement so that the building block concrete blocks are completely embedded in the concrete.

[0065] (4) Fill the gaps between the concrete blocks with the same concrete grout and cover the concrete blocks, then level it; the same concrete grout is the same as the road surface concrete;

[0066] (5) Once the concrete in the block area has completely solidified, grind and polish the block area to expose the block.

[0067] It should be noted that the concrete blocks prepared by the method of this application have relatively rough splits and retain irregular protrusions. When used to construct artistic pavements, the concrete blocks will bond more tightly to the pavement concrete, thus preventing them from falling off.

[0068] The above is a detailed description of the preferred embodiments of this application. However, the invention of this application is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
