Description

Technical Field

[0001] This utility model relates to the field of building component technology, specifically high-strength concrete blocks. Background Technology

[0002] Concrete blocks are block-shaped building materials made by mixing cement, sand, stone and other cementing materials with aggregates in a certain proportion, and then mixing, molding and curing them. They have a wide range of uses, including building wall construction, partition wall construction, foundation and municipal facilities. They have the characteristics of high strength, good durability and convenient construction. They can also utilize industrial waste and meet environmental protection and energy-saving requirements. They are one of the main wall materials to replace clay bricks and are widely used in modern buildings.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Existing concrete blocks have significant shortcomings in strength, making it difficult to meet the requirements for constructing high-strength walls. Due to limitations in material proportions, molding processes, and curing conditions, the internal porosity of the blocks is relatively high, resulting in weak crack resistance and impact resistance. They are prone to cracking under load or environmental influences, affecting structural safety and durability. Furthermore, to compensate for the lack of strength, it is necessary to increase the wall thickness or adopt composite structures, which not only increases self-weight and space occupation but may also increase construction costs. In scenarios with stringent requirements for material strength, such as super high-rise buildings and bridge foundations, they are difficult to replace high-strength masonry or reinforced concrete structures, thus limiting their application scope. Utility Model Content

[0005] The purpose of this invention is to provide high-strength concrete blocks to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength concrete block, comprising a concrete block body, wherein a plurality of longitudinal steel bars are fixedly installed inside the concrete block body, a plurality of steel fibers are fixedly installed inside the concrete block body, and three stirrups are fixedly installed on the outer surface of the longitudinal steel bars.

[0007] More preferably, the concrete block body has several holes inside.

[0008] More preferably, a transverse partition is fixedly installed inside the concrete block body, and a longitudinal partition is fixedly installed inside the concrete block body.

[0009] More preferably, a number of first diagonal bracing steel bars are fixedly installed inside the concrete block body.

[0010] More preferably, a number of second diagonal bracing steel bars are fixedly installed inside the concrete block body.

[0011] More preferably, the outer surfaces of the longitudinal reinforcing bars, stirrups, first diagonal bracing bars, and second diagonal bracing bars are all threaded.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Holes are made in the center of the blocks to avoid the cracking risk caused by the thermal expansion and contraction of concrete, indirectly improving the structural stability and strength of the blocks. By adding several longitudinal steel bars, the tensile strength of the blocks is enhanced. Stirrups are then used to encircle the longitudinal steel bars, forming a regular steel mesh skeleton. This ensures that the longitudinal steel bars are accurately positioned during concrete pouring, preventing displacement and allowing them to directly bear the shear force generated by the load, preventing the formation and propagation of diagonal cracks and avoiding sudden brittle failure of the components due to shear force. All steel bar surfaces are threaded to increase the contact area between the steel bars and concrete, making the stress distribution more uniform, reducing local stress concentration, and delaying the generation and propagation of concrete cracks. Finally, steel fibers are added to the concrete, which can also effectively prevent concrete cracking and enhance the concrete strength. Attached Figure Description
