Technical Field

[0001] This utility model relates to the field of cement brick technology, and in particular to a seismic-resistant and heat-insulating cement brick. Background Technology

[0002] In the construction industry, the production of high-quality cement bricks plays a decisive role in the quality and performance of various construction projects. In practical applications, the production of cement bricks typically requires the following key technologies:

[0003] 1. Raw material selection: Select cement of specific quality to provide basic strength guarantee for cement bricks;

[0004] 2. Raw material mixing: Mix cement and other additives in precise proportions;

[0005] 3. Mold structure: Molds of various specifications and shapes are designed according to different construction needs.

[0006] Existing traditional cement bricks do not have earthquake resistance. In the event of an earthquake, especially a major earthquake, cement bricks are often the first to collapse. In order to enhance the earthquake resistance of buildings and reduce loss of life and property during an earthquake, there is an urgent need for a type of cement brick with earthquake resistance. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a seismic-resistant and heat-insulating cement brick, solving the problem that traditional cement bricks do not have seismic resistance, and that cement bricks are often the first to collapse during earthquakes, especially major earthquakes. In order to enhance the seismic performance of buildings and reduce loss of life and property during earthquakes, there is an urgent need for a seismic-resistant cement brick.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An earthquake-resistant and heat-insulating cement brick includes a cement brick body with rectangular weight-reducing holes spaced out in an alternating pattern. The rectangular weight-reducing holes are filled with heat-insulating blocks. The cement brick body is constructed from cement, aggregate, and glass fiber. The rectangular weight-reducing holes are formed by polyurethane foam. All corners of the cement brick body are rounded.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] I. The cement brick body is constructed from cement, aggregate, and glass fiber, which greatly enhances the integrity of the cement brick body and effectively improves its seismic resistance. The edges and corners of the cement brick body are rounded to prevent stress concentration when the cement brick body is stretched, thus preventing the cement brick body from cracking.

[0024] This application provides a seismic-resistant and heat-insulating cement brick, effectively solving the problem that existing traditional cement bricks lack seismic resistance, and are often the first to collapse during earthquakes, especially major earthquakes. To enhance the seismic performance of buildings and reduce loss of life and property during earthquakes, there is an urgent need for a seismic-resistant cement brick. The cement brick body is constructed from cement, aggregate, and glass fiber, greatly enhancing its integrity and effectively improving seismic resistance. The edges and corners of the cement brick body are rounded to prevent stress concentration under tension and prevent breakage. The staggered arrangement of the insulation blocks effectively prevents linear heat transfer, thus improving seismic strength and insulation. Reinforcing bars inserted into the longitudinal connecting holes connect the upper and lower cement brick bodies into a single unit, while reinforcing bars inserted into the transverse connecting holes connect the left and right cement brick bodies into a single unit, preventing displacement at the connection points and preventing tilting during stacking, thereby increasing the strength of the connection points.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application effectively solves the problem that existing traditional cement bricks do not have earthquake resistance, and that cement bricks are often the first to collapse during earthquakes, especially major earthquakes. To enhance the earthquake resistance of buildings and reduce loss of life and property during earthquakes, there is an urgent need for a type of cement brick with earthquake resistance. The overall approach is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a seismic and heat-insulating cement brick, including a cement brick body 1, rectangular weight-reducing holes 2 interlaced on the cement brick body 1 for weight reduction, and heat-insulating blocks 3 for heat insulation filled inside the rectangular weight-reducing holes 2. The cement brick body 1 is composed of cement, aggregate and glass fiber casting, and the rectangular weight-reducing holes 2 are formed by polyurethane foaming.

[0028] All corners of the cement brick body 1 are rounded. The cement brick body 1 is symmetrically provided with longitudinal connecting holes 4 for longitudinal connection and transverse connecting holes 5 for transverse connection.

[0029] The rectangular weight reduction hole 2 has symmetrically arranged pins 6 for locking the heat insulation block 3, and the heat insulation block 3 has symmetrically opened pin grooves 7 for locking the pins 6.

[0030] Cement brick body 1: As the main body of the cement brick, it bears and supports the entire structure of the cement brick and is the basis for the attachment and function of other components;

[0031] It is constructed from cement, aggregate and glass fiber. The three materials work together to enhance the integrity and improve the seismic resistance. Cement provides the foundation strength, aggregate enhances the structural stability, and glass fiber, with its high tensile strength, strengthens the overall structure like steel bars and improves the seismic performance.

[0032] The corners are rounded to avoid stress concentration when subjected to external forces such as tension, thus preventing the main body from cracking and further improving earthquake resistance.

[0033] The longitudinal connection hole 4 and the transverse connection hole 5 are used to connect other cement brick bodies 1 in the longitudinal and transverse directions, respectively. By inserting steel bars, a stable connection with the adjacent cement brick bodies 1 is achieved, thereby enhancing the overall strength of the wall.

[0034] Rectangular weight-reducing holes 2: These are staggered on the main body of the cement brick 1. The purpose is to reduce the overall weight of the cement brick, making it easier to carry and transport during construction. At the same time, they may also optimize the thermal performance of the cement brick to some extent.

[0035] Insulation material containment: Its interior is used to fill the insulation material insulation block 3, providing space for achieving the insulation function;

[0036] Insulation block 3: It is made of polyurethane foam and filled inside the rectangular weight-reducing holes 2, and is arranged in an alternating manner. It can effectively prevent the straight-line transfer of heat, achieve good heat insulation effect, and improve the heat insulation performance of cement bricks.

[0037] Longitudinal connection hole 4: Symmetrically opened on the cement brick body 1, by inserting steel bars in it, the upper and lower cement brick bodies 1 are connected into a whole, which enhances the longitudinal connection strength of the wall, avoids displacement at the connection, and prevents tilting in the vertical direction during stacking;

[0038] Horizontal connecting hole 5: It is also symmetrically opened on the cement brick body 1. After inserting the steel bar, the two cement brick bodies 1 on the left and right can be connected into a whole, which enhances the horizontal connection strength of the wall, avoids horizontal displacement at the connection, and ensures that the left and right directions are neat when stacking, and does not become skewed.

[0039] Pin 6: Symmetrically set inside the rectangular weight reduction hole 2, it cooperates with the pin groove 7 on the heat insulation block 3 to lock the heat insulation block 3, so that the heat insulation material heat insulation block 3 is fixed in the rectangular weight reduction hole 2, preventing it from shifting or falling off during the use of cement bricks, and ensuring the stable performance of heat insulation function.

[0040] Pin groove 7: Symmetrically opened on the heat insulation block 3, and cooperates with the pin block 6 inside the rectangular weight reduction hole 2, so that the heat insulation block 3 can be firmly fixed inside the rectangular weight reduction hole 2, and maintain the stability of the heat insulation structure.

[0041] Working principle:

[0042] The first step involves casting the main body 1 of the cement brick, which is composed of cement, aggregate, and glass fiber. The rectangular weight-reducing holes 2 are formed by polyurethane foam. The cement used is 52.5 grade ordinary Portland cement, which has higher early strength and greater potential for later strength growth. This allows the reinforcing layer to achieve high strength within a short time after the cement brick is produced, facilitating faster production and construction. Furthermore, during long-term use, the strength continues to increase over time, ensuring the reinforcing layer can provide stable and long-lasting reinforcement. The aggregate is high-quality quartz sand that has undergone rigorous screening. Its particles are regularly shaped, have smooth surfaces, and a gradation range controlled between 0.3 and 2 mm, resulting in denser aggregate packing. This increases the density of the reinforcing layer, reduces internal porosity, lowers the possibility of water penetration, and improves the durability of the cement brick. Glass fiber is added at a rate of 0.1% to 0.3% of the cement mass. The addition of glass fiber, with its high strength and elastic modulus, significantly improves the tensile strength of the reinforcing layer and generates a strong bond with the cement matrix, distributing the tensile force evenly throughout the reinforcing layer. Under dynamic loads such as earthquakes, the fiber absorbs energy, enhancing the toughness of the cement brick body 1 layer and preventing cracks from rapidly penetrating the entire brick. This ensures that the cement brick maintains a certain load-bearing capacity even under large deformations. The edges and corners of the cement brick body 1 are rounded to prevent stress concentration when subjected to tension, thus preventing the cement brick body 1 from breaking. The staggered arrangement of the insulation blocks 3 effectively prevents the straight-line transfer of heat, allowing heat to be insulated, thereby improving seismic resistance and thermal insulation.

[0043] The second step involves inserting steel bars into the longitudinal connecting hole 4 to connect the upper and lower cement brick bodies 1 into a whole, and inserting steel bars into the transverse connecting hole 5 to connect the left and right cement brick bodies 1 into a whole, preventing displacement at the connection point and preventing skewing during stacking, thus improving the strength of the connection point.

[0044] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
