Transversal-hole temperature-insulating concrete hollow brick

Abstract

A transversal-hole temperature-insulating concrete hollow brick of which the technical design points includes following characteristics: The side plates at the two sides of the brick is widened, wherein the side plates of the concrete hollow brick is aligned with inner side surfaces of a protruding rib on the concrete hollow brick, so that the side plates and the inner side surfaces of the protruding rib are designed in the same straight line; by means of the design, the pressure at the top and the bottom of the brick is not borne by a upper transversal connecting plate and a lower transversal connecting plate of the concrete hollow brick, and the concrete hollow brick is enhanced in seismic behavior and pressure resistance since the upper pressure and the lower pressure are directly acted on the top of the side plates. Upper joint surfaces and lower joint surfaces of an upper concrete hollow brick and a lower concrete hollow brick are designed into a planar contact structure so that mortar, when being used for filling a gap, is free from sliding downwardly and a gap is not formed, so that the concrete hollow brick is enhanced in seismic behavior and pressure resistance. By means of arrangement of a cold-hot bridge separating trough behind the transversal connecting plates, heat transfer in the concrete hollow brick is blocked so that not only is the temperature-insulating coefficient improved but also an object of reducing the weight is achieved. The concrete hollow brick is simple in manufacturing processes and is easy to use.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a horizontal hole thermal insulation concrete hollow block capable of compressive resistance, flexural resistance and earthquake resistance. Background technique [0002] In the existing concrete hollow blocks for construction, the design mainly focuses on saving materials and reducing weight. "Patent: ZL201220107883.2" has advantages in manufacturing process, weight and consumables, but in the actual construction industry When applying, we should not only consider the weight and consumables, but also consider its anti-seismic performance and compressive performance. If only the weight is considered and the side panels are made very thin, most of the vertical pressure between the blocks will be from the vertical to the horizontal. The compressive and flexural strength of concrete hollow blocks is greatly reduced, and the blocks are prone to cracking or the upper and ...

[0002] In the existing concrete hollow blocks for construction, the design mainly focuses on saving materials and reducing weight. "Patent: ZL201220107883.2" has advantages in manufacturing process, weight and consumables, but in the actual construction industry When applying, we should not only consider the weight and consumables, but also consider its anti-seismic performance and compressive performance. If only the weight is considered and the side panels are made very thin, most of the vertical pressure between the blocks will be from the vertical to the horizontal. The compressive and flexural strength of concrete hollow blocks is greatly reduced, and the blocks are prone to cracking or the upper and lower horizontal connecting plates are broken, and their seismic performance and compressive performance are poor; It is planar contact. The upper and lower connecting surfaces of the concrete hollow blocks designed in "Patent: ZL201120205264.2" are inclined surfaces. In addition, the concrete hollow block designed in "Patent: ZL201120205264.2" only has a cold and hot bridge partition groove in front of the horizontal connecting plate of the block, which leads to the unsatisfactory cold and heat conduction coefficient. , can not meet the best requirements, which not only affects the thermal insulation coefficient but also affects the weight reduction index
