To make the objects, technical solutions and advantages of the present disclosure more apparent, the present disclosure is further described in detail below with reference to specific embodiments.
In order to solve the problems that in the prior art, corners of hollow rotary hollow bricks, especially rectangular hollow bricks, are vertical, the phenomenon of edge knocking is easy to occur, in the process of building a wall, the mud hanging force in the vertical direction is poor, mud is easy to fall off, or the hollow bricks can not be hung on the wall, and the whole or part of the problems of construction are not utilized, the invention provides a hollow brick, which comprises: the hollow brick body, the adjacent both sides of hollow brick body become the radian, and the radian corresponds the central angle and is 5 ~ 40.
Meanwhile, the invention also provides a preparation method of the hollow brick, which comprises the following steps:
preparing a mould: firstly, preparing a rectangular model frame, then respectively fixing an upper radian plate on 4 edges of the rectangular model frame along the long edge, then removing 4 prisms of the model frame corresponding to the radian plates, wherein the tops of the radian plates protrude out of the model frame, the bottoms of the radian plates are flush with the bottom edges of the model frame, and then fixing the radian plates and the model frame on a bottom plate to form a hollow brick mold;

and (3) filling the reinforced hollow brick mold with the hollow brick filler, compacting, molding and fixing for 3-5 days, removing the mold, and continuing to maintain for 5-10 days.
The adjacent two sides of the hollow brick are of the arc structures directly, and performance tests show that the central angles corresponding to the arcs are within the range of 5-40 degrees, the compressive strength of the prepared hollow brick is equivalent to that of a normal rectangular hollow brick, but mud hanging degree is obviously increased, and simultaneously under the same pressure impact, the edge collision phenomenon is obviously reduced.
Meanwhile, in the preparation method, the special mold is adopted for preparing the hollow brick, the whole preparation process is simple, the mold is simple to assemble and can be repeatedly used, waste materials cannot be produced, the utilization rate of raw materials is improved, and the cost is reduced.
Specifically, for example, the hollow brick provided by the embodiment of the invention has the structure shown in fig. 1-2. And is prepared by the following method.
The hollow brick filler comprises the following components in percentage by mass: 60% of coal gangue powder, 15% of adhesive and 25% of other short fibers of felt fibers.
Preparing a mould: the method is characterized in that 12 materials with high compressive strength, such as steel or high polymer materials, are adopted, a rectangular model frame 1 is prepared firstly, adjacent sides of the rectangular model frame 1 are connected through screws, then 4
And (3) reinforcing the die: fixing and sealing the periphery of the hollow brick mould, wherein the periphery of the hollow brick mould can be made of high molecular materials, steel materials or fiber cloth soaked by cement paste, and the upper end of the hollow brick mould is provided with an opening for filling a filler;
and (3) filling the reinforced hollow brick mold with the hollow brick filler, injecting and compacting by air entrainment, removing the mold after molding and fixing for 3-5 days, and continuing to maintain for 5-10 days. In order to ensure the void ratio of the hollow brick, at least 1 cylindrical upright post 3 is arranged on the bottom plate, and the upright post direction forms a hollow 31 along the length direction of the hollow brick in the filling process.
The hollow brick of preparation, including the adjacent both sides of
Meanwhile, the hollow bricks with radian corresponding to central angles of 0 degree, 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees and 45 degrees are respectively prepared by adopting the method. The prepared hollow bricks are respectively built transversely and vertically, the wall body formed by building the wall is shown in fig. 3 and 4, no matter the wall body is built transversely or vertically, a first mud hanging groove 12 can be formed at the contact position of the arc edges of the two adjacent hollow bricks, and a second mud hanging groove 13 is formed between the 4 adjacent hollow bricks.
The performance of the prepared hollow bricks with different radians is tested by adopting the GB/T24492-2009 non-bearing concrete hollow brick standard, and the test results are shown in Table 1. Wherein, the joint of two hollow bricks is tested for the mud hanging strength. The gouge edge test adopts 5kg/cm2The number of the hollow bricks is 100, 5 groups are tested, and the average value is taken.
TABLE 1 Performance testing of hollow bricks
The data in table 1 show that the compressive strength of the hollow brick prepared in the embodiment of the present invention is not affected by the change of the edge into the circular arc, and meanwhile, the mud hanging strength and the breaking rate are improved, and in combination with the structure of the masonry, no matter the hollow brick prepared in the present application is horizontally or vertically masonry, the first mud hanging groove 12 is formed between two adjacent bricks, and because the first mud hanging groove 12 has an inward radian, when the hollow brick is horizontally masonry, the first mud hanging groove 12 is horizontal and vertical to the direction of gravity. When the wall surface is filled with mortar, the upper side of the first mud hanging groove 12 has a drainage function, the mortar is drained into the first mud hanging groove 12, meanwhile, the penetration of the mortar into gaps is increased under the action of the lower side of the first mud hanging groove 12, the mud hanging strength is increased, along with the increase of the circular arc central angle, the drainage radian of the first mud hanging groove 12 is increased, the vertex angle of the first mud hanging groove 12 is increased, when the two reach balance, namely the radian corresponds to the central angle of 30 degrees, the drainage radian and the vertex angle of the first mud hanging groove 12 reach balance, therefore, the mud hanging strength is maximum, when the central angle continues to increase, the drainage radian continues to increase and the vertex angle of the first mud hanging groove 12 also increases, so that the clamping force of the first mud hanging groove 12 on the mortar entering through drainage is gradually reduced, the mud hanging strength is caused, even the clamping force is lower than that the central angle is 0 degree, and the first mud hanging groove 12 has the drainage function of the first mud hanging groove from the beginning, gradually changes into a plug flow effect, and the mortar can not be adhered.
Meanwhile, if the hollow brick is used for vertical wall building, the direction of the first mud hanging groove 12 at the moment is the same as the direction of gravity, when mortar is filled on the wall surface again, the first mud hanging groove 12 is equivalent to a slot with a very sharp vertex angle, the mortar is equivalent to a bolt, and when the mortar is filled, the first mud hanging groove 12 clamps the mortar to reduce the flowability of the mortar, so that the mud hanging strength is enhanced. And meanwhile, when the concrete in the wall body is filled in the vertical wall building, the second mud hanging groove 13 is equivalent to the hollow of a brick, and the concrete can be filled, so that the strength of the wall body is increased, and the void ratio of the hollow brick can not be influenced.
In the embodiments of the present invention, the installation manner that is not described in detail with respect to the preparation of the mold is available to those skilled in the art as long as the installation function can be achieved.
Those of ordinary skill in the art will understand that: the discussion of any embodiment above is meant to be exemplary only, and is not intended to intimate that the scope of the disclosure, including the claims, is limited to these examples; within the idea of the present disclosure, features in the above embodiments or in different embodiments may also be combined, steps may be implemented in any order, and there are many other variations of different aspects of one or more embodiments of the present description as described above, which are not provided in detail for the sake of brevity.
