Description

A self-clamping-free hollow concrete block

technical field

The utility model relates to the field of building wall materials, in particular to a self-clamping-free hollow concrete block.

Background technique

At present, in construction projects, there are various types of wall materials, including traditional masonry materials, and new wall materials that are material-saving, energy-saving, and environmentally friendly. Among them, because the production of traditional building wall materials has a great adverse impact on the environment, and is not conducive to energy saving and material saving, its application in engineering has become less and less. However, new energy-saving and environment-friendly wall materials have been rapidly developed in construction engineering and are being used more and more widely. In particular, the new lightweight concrete block has been widely used in construction projects due to its advantages of energy saving and environmental protection, and has become the main material for wall masonry. Nevertheless, some novel wall materials such as existing concrete blocks still have many disadvantages, the most important being that the building speed is slow and the construction efficiency is low.

There are various forms of concrete blocks, and the common ones are solid and hollow. When these blocks are used to build walls, they must be built with bonding materials (cement mortar, etc.), which not only has low construction efficiency, but also consumes a lot of cement, and the integrity of the masonry is also poor. . For this reason, a new type of concrete block without cement masonry has emerged as the times require. It only needs to assemble the blocks together in a certain order to realize the wall masonry, thereby improving the construction speed and reducing the amount of cement. dosage. However, this assembly is mainly locked in one direction in the horizontal direction, but cannot be locked in the vertical direction. The connection between the upper and lower layers is not firm enough, and the integrity is slightly poor.

Contents of the invention

The technical problem to be solved by the utility model is to provide a self-clamping free hollow concrete block with simple structure, simple structure, efficient splicing, horizontal and vertical two-way locking and other functions.

The technical scheme adopted by the utility model to solve the technical problem is: to provide a self-clamping free hollow concrete block, including a concave-convex hollow block, and the concave-convex hollow block is composed of two long blocks arranged in parallel and opposite to each other. It consists of a number of short blocks arranged perpendicular to the long block, the short blocks are evenly arranged along the direction of the long block, the upper end of the short block has upward protrusions to form a convex clip, and the lower end of the short block has an inward The groove forms a concave card groove, a square bump is arranged in the middle of the upper end of the left side of the concave-convex hollow block, and a square bump is arranged on the upper end of the right side of the concave-convex hollow block corresponding to the square bump. Square card slot.

The size of the convex clamping strip matches the concave clamping groove and both are "T" shaped.

The size of the square bump matches the square slot.

The concave-convex hollow block can be divided into a left matching block and a right matching block from the middle section.

Beneficial effect

The utility model relates to a self-clamping-free hollow concrete block, which has a simple structure and can be combined freely. It has the functions of high-efficiency splicing, horizontal and vertical two-way locking, etc., and can double the effect of improving the construction speed and enhancing the integrity of the masonry. , and not bonded with masonry mortar.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

As shown in Figures 4-8, the embodiment of the present invention relates to a self-clamping type free hollow concrete block, which includes a concave-convex hollow block 1, and the concave-convex hollow block 1 is composed of two parallel and oppositely arranged long block and several short blocks vertically arranged with the long block, the short blocks are evenly arranged along the direction of the long block, the upper end surface of the short block has an upward protrusion to form a convex clamping strip 5, and the lower end surface of the short block There is an inward groove to form a concave card groove 3, and a square bump 4 is arranged in the middle of the upper end of the left side 2 of the concave-convex hollow block 1, and the upper end of the right side 9 of the concave-convex hollow block 1 is connected to the A square slot 7 is arranged at a position corresponding to the square protrusion 4 .

The size of the convex clamping strip 5 matches that of the concave clamping groove 3 and both are "T" shaped.

The size of the square bump 4 is matched with the square slot 7 .

The concave-convex hollow block 1 can be divided into a left matching block 10 and a right matching block 20 from the middle section. .

Example 1

As shown in Figure 9, the concave-convex hollow blocks 1 are connected end to end in sequence, the square convex block 4 is inlaid with the square slot 7 on the concave-convex hollow block 1 adjacent to the right, and the convex clip strip 5 is inlaid with the concave-convex hollow block adjacent to the upper end. The concave slot 3 on the lower end surface of the block 1 is inlaid to limit the sliding of the block from up, down, left, and right. After the concave-convex hollow blocks 1 are arranged, insert the left matching block 10 and the right matching block 20 into the corresponding positions at the two ends of the wall. The entire wall is completely filled.
