Abstract
Description
Technical Field
[0001] This utility model relates to the field of building materials technology, specifically to concrete blocks with crack-resistant properties. Background Technology
[0002] Concrete blocks are building masonry materials made from cement and aggregates (sand, stone, cinder, fly ash, etc.) as the main raw materials, through mixing, molding, and curing. According to different production processes and uses, they can be divided into two main categories: ordinary concrete blocks and lightweight aggregate concrete blocks. Concrete blocks are widely used in the construction field because of their high load-bearing capacity, frost resistance, corrosion resistance, and long service life.
[0003] During the design process of this utility model, the following problems were discovered in the existing technology:
[0004] However, existing concrete blocks are prone to cracking due to temperature differences during use, have poor crack resistance, and require additional anti-crack mesh after construction. This results in low construction efficiency. Furthermore, most existing concrete blocks are regular cubes, which easily lead to through-joints during construction, making it difficult for the masonry to meet the seismic requirements of buildings. Utility Model Content
[0005] The purpose of this invention is to provide concrete blocks with crack-resistant properties to solve the problem of poor crack resistance of existing concrete blocks mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete block with crack-resistant function, comprising a concrete outer layer, a trapezoidal groove at the top of the concrete outer layer, a trapezoidal tenon at the bottom of the concrete outer layer, a grouting through hole inside the concrete outer layer, reinforcing ribs inside the concrete outer layer, and a crack-resistant mesh inside the concrete outer layer.
[0007] More preferably, the outer layer of the concrete is internally incorporated with crack-resistant fibers.
[0008] More preferably, the trapezoidal grooves are symmetrically opened on the left and right sides of the top of the concrete outer layer with the center line of the concrete outer layer as the axis, and the trapezoidal grooves are inverted trapezoids.
[0009] More preferably, the trapezoidal tenons are symmetrically opened on the left and right sides of the bottom of the outer concrete layer with the center line of the outer concrete layer as the axis, and the trapezoidal tenons and trapezoidal grooves are distributed vertically along the vertical direction. The outer wall dimension of the trapezoidal tenons is the same as the inner wall dimension of the trapezoidal grooves.
[0010] More preferably, the grouting through hole is located in the middle of the trapezoidal groove, and the grouting through hole is located inside the outer layer of concrete.
[0011] More preferably, the reinforcing ribs are arranged in a crisscross pattern inside the outer layer of concrete, and the reinforcing ribs are distributed in two layers inside the outer layer of concrete.
[0012] More preferably, the crack-resistant mesh is disposed under the surface of the outer wall of the concrete outer layer, and the crack-resistant mesh is distributed under the outer surface of the concrete outer layer around all four sides.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] The concrete block is internally reinforced with ribs and a crack-resistant mesh. During use, these ribs and mesh provide a stress opposite to the cracking stress when the block cracks, thus enhancing its crack resistance. This effectively reduces cracking caused by temperature stress, shrinkage stress, or load, improving the block's crack resistance. During construction, the trapezoidal tenon at the bottom of the upper block is placed within the trapezoidal groove at the top of the lower block, resulting in staggered construction that effectively prevents through-joints between blocks, improving the masonry's seismic performance. The vertically connected grouting holes inside the upper and lower blocks facilitate subsequent grouting and improve the overall masonry's shape. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1 to 3This utility model provides a technical solution: a concrete block with crack resistance function, including a concrete outer layer 1, a trapezoidal groove 2 on the top of the concrete outer layer 1, a trapezoidal tenon 3 at the bottom of the concrete outer layer 1, a grouting through hole 4 inside the concrete outer layer 1, a reinforcing rib 5 inside the concrete outer layer 1, and a crack-resistant mesh 6 inside the concrete outer layer 1.
[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the outer concrete layer 1 contains crack-resistant fibers.
[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the trapezoidal groove 2 is symmetrically opened on the left and right sides of the top of the concrete outer layer 1 with the center line of the concrete outer layer 1 as the axis, and the trapezoidal groove 2 is an inverted trapezoid.
[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the trapezoidal tenon 3 is symmetrically opened on the left and right sides of the bottom of the concrete outer layer 1 with the center line of the concrete outer layer 1 as the axis, and the trapezoidal tenon 3 and the trapezoidal groove 2 are distributed vertically in the vertical direction. The outer wall size of the trapezoidal tenon 3 is the same as the inner wall size of the trapezoidal groove 2.
[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the grouting through hole 4 is opened in the middle of the trapezoidal groove 2, and the grouting through hole 4 is opened through the interior of the concrete outer layer 1.
[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the reinforcing ribs 5 are arranged in a crisscross pattern inside the outer concrete layer 1, and the reinforcing ribs 5 are distributed in two layers inside the outer concrete layer 1.
[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the crack-resistant mesh 6 is set under the surface of the outer wall of the concrete outer layer 1, and the crack-resistant mesh 6 is distributed under the outer surface of the concrete outer layer 1 around all four sides.
[0027] As in the process Figure 1 , Figure 2 and Figure 3 As shown, this crack-resistant concrete block works as follows during use:
[0028] Firstly, during the manufacturing process, fine crack-resistant fibers are incorporated into the outer concrete layer 1, enhancing its crack resistance. Simultaneously, double-layered reinforcing ribs 5 are installed inside the outer concrete layer 1, and crack-resistant mesh 6 is pre-embedded beneath the surface of the outer concrete layer 1. The reinforcing ribs 5 and the crack-resistant mesh 6 exert opposing forces within the masonry to counteract the forces causing cracking, effectively reducing cracking during use and thus enhancing the masonry's crack resistance. When used for masonry construction, the upper layer of blocks is joined with the trapezoidal tenon 3 at the bottom and the trapezoidal groove 2 at the top of the lower layer, with staggered distribution between the upper and lower layers to effectively prevent through-joints after construction, further improving the masonry's seismic performance. A grouting through-hole 4 is provided in the middle of the masonry, facilitating grouting after construction, resulting in good overall forming effect and high strength.
