Description

Technical Field

[0001] The present disclosure relates to building material, and more particularly to a corner block and a block kit comprising the same.

BACKGROUND

[0002] Generally, a solid waste involved in the present world includes: industrial solid wastes, domestic wastes, construction wastes, urban sludge, and crop straw wastes. The industrial wastes include, but not limited to, a waste slag, a slag and corner wastes of industrial products. The domestic wastes include, but not limited to, waste papers, waste furniture, used plastic, packaging materials and surplus deteriorating foods, which are produced in daily life. The construction wastes include, but not limited to, cement blocks, bricks and decoration materials produced while old buildings are demolished. The urban sludge includes, but not limited to, sludge produced by sewage treatment, sludge excavated in urban underground projects, and sludge deposited in urban sewage all year round. The crop straw wastes include, but not limited to, rice straw, wheat straw, corn stalk, sorghum stalk, cotton straw, peanut straw, sesame straw, and rape straw. At present, there are many methods to deal with these various types of wastes. However, with the continuous development of the society, the various types of wastes have not been handled well and become increasingly serious social problems and continue to cause harm to the human living environment. At the same time, various methods for constructing walls are using cement mortar to block bricks into walls, or after the frame structure is built, the wall plates are fixed to the frame structure. Only professional staff can implement these methods by using professional tools and equipment. The built walls are all base blank walls without any decoration. After the wall is built, if it needs to be renovated and decorated, the building material used for building the wall cannot be used repeatedly for construction and demolition. As a result, a large amount of building materials is wasted, and the disassembled construction waste cannot be decomposed and become new solid wastes, causing environmental pollution. In addition, a large number of skilled building workers are needed in a traditional wall building process, therefore causing a serious shortage of skilled building workers.

[0003] An existing recyclable block is provided with a concave-convex matching structure, all of the protruding structures of the blocks are discontinuous protruding portions configured on a top face of the block, and the protruding portions are all perpendicular to the top face. Thus, water may easily enter the block when the block is used in the environment with rainfall, therefore reducing the service life of the block, and further reducing the quality of the building.

Description of Embodiments

[0029] Technical solutions in embodiments of the present invention will be further clearly and completely illustrated below with reference to the attached drawings of the embodiments. Obviously, the described embodiments are merely a part of embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by one with ordinary skills in the art without any creative efforts, shall fall into the protection scope of the present invention.

[0030] Referring to FIG. 1, a building 900 constructed by a block kit provided by the present disclosure is illustrated in FIG. 1. The block kit includes a first block 100 for building a wall body of the building 900, a corner block 200 for being used at a corner position of the building 900, an adjusting block 300 for constructing a wall body at a position of doors, windows or the like, or for filling uneven gaps created at positions of one or more points of termination, and a reinforcement positioning rod 400 detachably inserted in the blocks when they are stacked upon each other. A plurality of corner blocks, first blocks and the adjusting blocks are stacked and interlocked so as to construct a stable building. The reinforcement positioning rod 400 is made of hollow metal, plastic or composite material, and may be used as a water supply pipe, a gas supply pipe, a power cable pipe, a communication cable pipe, and so on. The reinforcement positioning rod 400 may be a rod-like object in shape of circular, rectangular or other geometrical shape. When constructing the building, waterproof glue, fastening glue, structural glue, cement or other adhesive may be applied between each of the blocks to enhance the interlocking strength between the blocks. The block kit further includes a sealing gasket 500 sandwiched between two stacked blocks, and the stacked blocks can be any one of first block, corner block and adjusting block.

[0031] Referring to FIGS. 2-3, the corner block 200 is generally L-shaped and includes a first straight edge portion 201, a second straight edge portion 202 and a corner portion 203 connected between the first straight edge portion 201 and the second straight edge portion 202. The corner portion 203 is formed by connecting two edges with an angle of approximately 90° therebetween. Therefore, the first straight edge portion 201 extends in a direction perpendicular to an extension direction of the second straight edge portion 202. A concave structure 10 is concaved from one end of the first straight edge portion 201 away from the corner portion 203. The concave structure 10 is also formed at an end of the second straight edge portion 202 away from the corner portion 203 and recessed inwards, and the concave structure 10 is configured for forming an interlocking structure when being latched with other blocks.

[0032] The corner block 200 includes an upper convex structure 11 arranged on a top face of the corner block 200 and a lower concave structure 12 arranged on a bottom face of the corner block 200. The upper convex structure 11 extends along a length direction of the top face, with a length of the upper convex structure equal to a length of the top face. Specifically, the upper convex structure 11 extends from the top face of the first straight edge portion 201 to the top face of the second straight edge portion 202 through the top face of the corner portion 203, namely, the upper convex structure 11 extends along the length direction of the top face of the whole corner block 200 to form an integrally non-interrupted structure. Accordingly, the lower concave structure 12 is a groove extending along the length direction of the bottom face of the whole corner block 200, by recessing from the bottom face to the top face, and specifically, the lower concave structure 12 extends from the bottom face of the first straight edge portion 201 to the bottom face of the second straight edge portion 202 through the bottom face of the corner portion 203. When the two blocks are stacked, the upper convex structure 11 is received in the lower concave structure 12 of the adjacent block, so as to realize the interlocking of the two blocks. It can be understood that, referring to FIG. 8, in other embodiments, a height H of the upper convex structure 11 is smaller than a depth D of the lower concave structure 12, so that when the upper convex structure 11 is received in the lower concave structure 12, so as to form a gap between the upper convex structure 11 and the lower convex structure 12, and the gap forms a horizontal line pipe slot 8 for receiving water supply pipes, electric wires, communication cables and the like, in the horizontal direction.

In the present disclosure, as the integrally non-interrupted upper convex structure is adopted, and the guiding face of the upper convex structure is inclined to the top face, it can be effectively achieved to prevent water from entering the block from the top face. In addition, since the guiding face is an inclined face, a better cooperation with the lower concave structure can be realized, so as to obtain effects of guiding and positioning.

[0034] In another embodiment, the corner block 200 further includes a positioning groove formed by removing the upper convex structure 11 on the top face of the corner portion 203.
