Description

Rib-aligned interlocking concrete hollow blocks

(1) Technical field

The utility model relates to a rib-aligned and occluded concrete hollow block, which belongs to the field of new wall building materials. the

(2) Background technology

Concrete hollow blocks have become the main wall materials for building wall renovation projects in my country because of their low cost and do not occupy or destroy land resources. Due to the existence of voids in traditional concrete hollow blocks, the masonry quality is difficult to guarantee, the shear strength and deformation resistance are poor, the wall is cracked, and the external wall seepage is serious. Therefore, there is an urgent need for a new type of concrete hollow block with superior performance. . the

(3) Contents of the invention

The technical problem to be solved by the utility model is to provide a new type of concrete hollow block, which has good thermal insulation and energy-saving performance. The block is made of cement fine stone concrete material, and it is characterized in that the upper and lower surfaces of the four side ribs of the concrete hollow block are divided into two parts: concave and convex, the upper four side ribs are convex inside and outside concave, and the four side ribs below are concave and inside convex. Each concrete hollow block is double hollow or single hollow, the left and right side ribs of the double hollow concrete block are equal, and the sum of the width of the left and right side ribs is equal to the width of the middle rib. Through rib alignment and occlusion, the vertical bearing capacity and shear capacity of the wall are improved, the seismic and crack resistance performance is improved, and the problems of water seepage of the outer wall are solved. the

In order to solve the above technical problems, the rib-aligned and occluded concrete hollow blocks provided by this design have the following characteristics: the ribs are aligned with each other, the force transmission is more clear, the effective width of the ribs is increased, and the vertical bearing capacity of the wall is improved; By interlocking each other, the shear resistance can be improved; the water seepage phenomenon of the external wall can be effectively solved; the insulation material is placed in the hollow of the concrete block to improve the thermal insulation and energy saving effect of the wall. the

As a technical feature of this design, after the block is formed, the insulation material is put into the hollow of the concrete block and sealed with cement mortar. This technology provides convenience for the storage, transportation and construction of compressed straw blocks, and effectively reduces the loss of mortar in the process of traditional wall masonry. the

The above-mentioned rib-aligned and occluded thermal insulation and energy-saving concrete hollow blocks are used. When building walls, the blocks are interlocked to form pin keys. The pin-bolt effect of the pin keys is the same as that of traditional blocks that generally undergo shear failure along the mortar surface when they are sheared. Compared with it, it can effectively improve the shear strength of masonry and improve the crack resistance and earthquake resistance of the wall. The rib-to-rib alignment increases the effective rib width of the block, the force transmission mode is clear, it is conducive to load bearing, and the vertical bearing capacity is greatly improved. the

The main content of this design is: on the four upper and lower side ribs of the concrete hollow block, the upper side ribs are designed and processed to be convex inside and concave outside, the height of the protrusion is the depth of the depression, and the width of the rib surface of the protrusion occupies the entire rib 2/5 of the surface width; the lower rib is designed and processed to be convex and concave, and the depth and width of the convex and concave are the same as the upper rib. In addition, the concrete hollow block can be designed as double hollow or single hollow, and the design of the upper and lower four ribs is the same as above. The side rib width is generally 2-3cm, the middle rib width is generally 4-6cm, and the height of the concave-convex part is generally 1-1.5cm. the

The utility model can effectively improve the vertical bearing capacity and shearing resistance of the wall body. The block is suitable for load-bearing walls and non-load-bearing walls of buildings, and has the advantages of heat preservation, energy saving, simple construction, low cost, and improved anti-seismic, anti-seepage and anti-crack properties. the

The utility model is mainly composed of concave and convex tooth grooves 1 on the surface of the lower rib of the block, side ribs 2 of the concrete hollow block, thermal insulation material 3, concave and convex tooth grooves 4 on the surface of the upper rib of the block, cement mortar 5, The concrete hollow block is composed of the middle rib 6 and other parts. the

Firstly, the mold is designed and manufactured according to the required size, and the weight of cement, sand, water and other components is weighed according to the material ratio, and mechanical mixing is adopted. After uniform mixing, the mixture is poured into the block mould, and after mechanical compaction, the mold is demoulded, and it is maintained under natural conditions until the block is dry. The size of the hollow can be determined according to the actual needs such as the size of the wall, and each block can be designed as a double hollow or a single hollow. It is advisable that the size of the internal thermal insulation material 3 is slightly smaller than the hollow size of the concrete hollow block and can be put into the hollow. the

When building the wall, put the thermal insulation material 3 into the rib-aligned and occluded concrete hollow blocks, and plaster the surface with cement mortar, and the height of the new plastered surface is parallel to the protruding alveoli of the original concrete hollow blocks.
