Description

Technical Field

[0001] This invention relates to cement concrete hollow brick masonry walls filled with fluidized soil. Background Technology

[0002] In the construction industry, traditional fired bricks or concrete bricks have many drawbacks when used for wall construction, such as cumbersome and time-consuming operations, long construction cycles, and environmental pollution. They do not conform to the concept of rapid construction. In response, some precast bricks made of concrete are available on the market. After the bricks are assembled, concrete is poured into their cavities. This results in huge concrete consumption and high transportation costs. In addition, concrete has poor thermal insulation properties and is not suitable for construction in remote northern areas. If concrete is not poured, the overall structural strength of the wall will be insufficient, and it will also make it easier for snakes, rats, insects and ants to enter the room. Summary of the Invention

[0003] The purpose of this invention is to provide a cement concrete hollow brick masonry wall filled with fluidized soil, which has the advantages of low concrete consumption, good thermal insulation performance, protection against snakes, rodents, insects and ants, and high structural strength at a low cost.

[0004] The technical solution of the present invention is as follows: A wall constructed of cement concrete hollow bricks filled with fluidized soil includes a wall and a column located at the corner of the splicing of adjacent walls. The wall and the column are composed of multiple cement concrete hollow bricks spliced ​​together in an alternating manner. The cement concrete hollow bricks include bricks precast from concrete. The bricks are cuboid in shape and include two cavities symmetrically arranged along the length direction. The cavities penetrate the bricks in the vertical direction. The upper and lower surfaces of the bricks are respectively provided with mutually compatible and mutually blocking grooves and platforms. The platforms and grooves extend along the length direction of the bricks. The cavities of each layer of cement concrete hollow bricks are connected one by one along the height direction to form a vertically connected pouring channel. The pouring channel corresponding to the wall part is filled with a wall core formed by the solidification of fluidized soil. The pouring channel corresponding to the column part is filled with a steel cage and filled with a column core formed by the solidification of concrete.

[0005] The beneficial effects of this technical solution are as follows: In this solution, both the wall and column parts are constructed by interlocking hollow cement concrete bricks, making the construction process as convenient, quick, and efficient as assembling building blocks. Subsequently, for the pouring channels corresponding to the column parts, a reinforcing cage needs to be placed inside and concrete poured. The high compressive strength of concrete and the high tensile strength of reinforcing steel enhance the load-bearing capacity. Since the column is the core load-bearing component of the building, a reinforced concrete structure must be used. However, the corresponding wall part, since it does not require load-bearing, can be constructed using locally sourced fluidized soil. The low cost and good thermal insulation properties of soil improve the wall's insulation performance. Furthermore, because the wall occupies a larger volume than the column, using fluidized soil instead of concrete in the pouring channels for the wall part not only reduces concrete usage but also effectively utilizes the low cost and high insulation properties of fluidized soil. Moreover, the main raw material of fluidized soil is soil, which can be sourced locally, thus reducing transportation costs.

[0006] Based on the above scheme, further improvements are made as follows: the cavity is a structure with narrowed upper and lower ends and an expanded middle area. The reinforcing cage includes vertical bearing bars, and multiple support units are strung on the vertical bearing bars. Each support unit corresponds to the cavity of a layer of cement concrete hollow bricks. The support unit includes a linkage mechanism and telescopic joints located at both ends of the linkage mechanism. The linkage mechanism includes two support linkages that are hinged to each other at one end. The telescopic joint includes a sleeve and two vertical rods. One end of the vertical rod has a sliding member that slides inside the sleeve. Both ends of the sleeve have stop parts to stop and cooperate with the sliding member. The other end of the vertical rod is hinged to the other end of the support linkage. Furthermore, the reinforcing cage includes a rotating top support rod, which is correspondingly set with the vertical bearing reinforcement. The rotating top support rod is equipped with a rotating top support unit corresponding to the support unit. The rotating top support unit includes an arc-shaped rod arranged in the horizontal plane. When the arc-shaped rod rotates with the rotating top support rod, it can push the hinge point of the two support rods toward the axis away from the vertical rod, so as to reduce the included angle of the two support rods and the vertical rod of the expansion joint extends out from the corresponding sleeve.

[0007] The beneficial effects of this technical solution are as follows: During use, because the cavity has a structure with narrow ends and an expanded middle area, sufficient space can be provided for the deformation of each support unit of the vertical bearing reinforcement. Initially, each support unit's connecting rod is in a vertical state. When it is placed into the corresponding pouring channel of the column along with the reinforcing cage, each expansion joint is in a contracted state due to its own weight. Subsequently, by rotating the rotating top support rod, each rotating top support unit of the rotating top support rod supports the corresponding support unit. Specifically, as the rotating top support rod rotates, each arc-shaped rod rotates synchronously, thereby pushing the hinge point of the two supporting connecting rods of the corresponding support unit towards the axis away from the vertical rod, causing the included angle of the two supporting connecting rods to gradually decrease. This manifests as the two supporting connecting rods protruding laterally in the horizontal plane. Thus, the outwardly protruding supporting connecting rods and the solidified concrete can form a vertical pushing structure, allowing the reinforcing steel to bear more vertical force and avoiding the problem of insufficient concrete in the pouring channel. This design avoids the problem of insufficient vertical load-bearing capacity when relying solely on the friction between the steel bars and concrete in the steel cage. Furthermore, because each supporting rod protrudes into the cavity of the corresponding hollow concrete brick, and because the cavity has a constricted upper and lower end and an expanded middle area, the vertical load-bearing capacity between the supporting unit and the concrete, as well as the hollow concrete brick, is further improved. This significantly enhances the vertical load-bearing capacity of the column, especially its tensile strength. It effectively avoids the load-bearing capacity shortcomings caused by using hollow concrete bricks for column assembly instead of cast-in-place concrete columns. This fully utilizes the speed of hollow concrete brick assembly while also improving the vertical load-bearing capacity of the column. Moreover, during the outward protrusion of the supporting rods, the expansion joints at both ends can extend, keeping the height of the supporting rods constant. After the concrete is poured, the movable expansion joints are locked by the solidified concrete, forming an integrated load-bearing structure.

[0008] Based on the above scheme, further improvements are made as follows: the reinforcing cage has multiple vertical bearing bars evenly distributed along its circumference, and corresponding rotating top support rods. This arrangement allows for more uniform overall stress distribution, preventing eccentric loading to one side.

[0009] Based on the above scheme, further improvements are made as follows: Multiple positioning discs are evenly fitted along the length of the reinforcing cage. Each positioning disc has a first through hole and a second through hole corresponding to the rotating top support rod and the vertical bearing reinforcement, respectively. The diameter of the second through hole is larger than the outer diameter of the sleeve. The positioning discs not only position and guide the reinforcing cage, rotating top support rod, and vertical bearing reinforcement, but also enhance the overall vertical bearing capacity by utilizing the interlocking action of the positioning discs and the concrete.

[0010] Based on the above solution, a further improvement is made as follows: the two ends of the sleeve have conical tips to facilitate guiding it through the corresponding second perforation. The tips facilitate guiding the sleeve in and out of the corresponding second perforation, preventing the sleeve from getting stuck outside the second perforation.

[0011] Based on the above scheme, the following improvement is made: the cavity of the pouring channel that constitutes the corresponding column part is cylindrical.

[0012] Based on the above scheme, further improvements are made as follows: for each layer of cement concrete hollow bricks, there is one support unit and one rotating top support unit corresponding to every other layer. Attached Figure Description

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0024] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0025] Specific embodiments of the cement concrete hollow brick masonry wall constructed using fluidized soil casting and filling according to the present invention are as follows: Figure 1-7As shown, the wall constructed with cement concrete hollow bricks filled with fluidized soil includes wall 1 and column 2 located at the corner of the joint between adjacent walls 1. Wall 1 and column 2 are composed of multiple cement concrete hollow bricks 3 spliced ​​together vertically. The cement concrete hollow brick 3 includes a brick body made of precast concrete. The brick body is rectangular and includes two cavities 31 symmetrically arranged along the length direction. The cavities 31 penetrate the brick body vertically. The upper and lower surfaces of the brick body are respectively provided with mutually compatible and blocking grooves 32 and platforms 33. The platforms 33 and grooves 32 extend along the length direction of the brick body. The cavities 31 of each layer of cement concrete hollow bricks 3 are connected one by one along the height direction to form a vertically connected pouring channel. The pouring channel 11 corresponding to the wall 1 is filled with a wall core formed by the solidification of fluidized soil. The pouring channel 21 corresponding to the column 2 is filled with a steel cage 4 and filled with a column core formed by the solidification of concrete. Both wall 1 and column 2 are constructed by interlocking hollow cement concrete bricks 3, making the assembly process as convenient, quick, and efficient as building with blocks. Subsequently, for the pouring channel corresponding to column 2, a reinforcing cage 4 needs to be placed inside and concrete poured. The high compressive strength of concrete and the high tensile strength of the reinforcing steel enhance the load-bearing capacity. Since column 2 is the core load-bearing component of the building, a reinforced concrete structure must be used. However, for wall 1, since it does not bear load, fluidized soil can be used locally. The inexpensive nature of soil and its good thermal insulation properties improve the insulation performance of wall 1. Furthermore, because wall 1 occupies a larger volume than column 2, using fluidized soil instead of concrete for the pouring channel not only reduces concrete usage but also effectively utilizes the low cost and high insulation properties of fluidized soil. Moreover, since the main raw material of fluidized soil is soil, it can be sourced locally, thus reducing transportation costs.

[0026] The cavity 31 has a structure with narrowed upper and lower ends and an expanded middle area. The reinforcing cage 4 includes vertical bearing bars 41, and multiple support units 411 are strung on the vertical bearing bars 41. Each support unit 411 is set in the cavity 31 of a layer of cement concrete hollow bricks 3. The support unit 411 includes a linkage mechanism and telescopic joints located at both ends of the linkage mechanism. The linkage mechanism includes two support connecting rods 4111 that are hinged to each other at one end. The telescopic joint includes a sleeve 4113 and two vertical rods 4114. One end of the vertical rod 4114 has a sliding member 4115, which slides in the sleeve 4113. Both ends of the sleeve 4113 have stop parts 4116 to stop and cooperate with the sliding member 4115. The other end of the vertical rod 4114 is hinged to the other end of the support connecting rod 4111. Furthermore, the reinforcing cage 4 includes a rotating top support rod 42, which is correspondingly arranged with the vertical bearing reinforcement 41. The rotating top support rod 42 is provided with a rotating top support unit 421 corresponding to the support unit 411. The rotating top support unit 421 includes an arc-shaped rod 4211 arranged in the horizontal plane. When the arc-shaped rod 4211 rotates with the rotating top support rod 42, it can push the hinge point of the two support connecting rods 4111 toward the axis away from the vertical rod 4114, so that the included angle of the two support connecting rods 4111 is reduced, and the vertical rod 4114 of the expansion joint extends out from the corresponding sleeve 4113.In use, because the cavity 31 has a structure with narrow ends and an expanded middle area, it can provide sufficient space for the deformation of each support unit 411 of the vertical bearing reinforcement 41. In the initial state, each support rod 4111 of each support unit 411 is in a vertical state. When it is placed into the corresponding pouring channel of the column 2 along with the steel cage 4, each expansion joint is in a contracted state due to its own weight. Then, by rotating the rotating top support rod 42, each rotating top support unit 421 of the rotating top support rod 42 supports the corresponding support unit 411. Specifically... As the rotating top support rod 42 rotates, each arc-shaped rod 4211 rotates synchronously, thereby pushing the hinge points of the two support connecting rods 4111 of each corresponding support unit 411 towards the axis away from the vertical rod 4114. This causes the included angle between the two support connecting rods 4111 to gradually decrease, resulting in the two support connecting rods 4111 protruding laterally in the horizontal plane. This allows the outwardly protruding support connecting rods 4111 and the solidified concrete to form a vertical pushing structure, enabling the reinforcing steel to bear more vertical force and preventing damage to the pouring channel. The internally poured concrete is insufficient, and the vertical bearing capacity is insufficient when relying solely on the friction between the steel bars and concrete of the steel cage 4 for vertical bearing. Moreover, since each supporting rod 4111 protrudes outward into the cavity 31 of the corresponding cement concrete hollow brick 3, and since the cavity 31 has a structure with narrowed upper and lower ends and an expanded middle area, the vertical bearing capacity between the supporting unit 411 and the concrete and the cement concrete hollow brick 3 is further improved. This significantly improves the vertical bearing capacity of the column 2, especially the vertical tensile capacity, thus effectively avoiding the bearing capacity shortcomings caused by the use of cement concrete hollow brick 3 splicing instead of formwork cast-in-place concrete columns in the column 2. This fully utilizes the quickness of cement concrete hollow brick 3 splicing while improving the corresponding vertical bearing capacity of the column 2. Furthermore, during the outward protrusion of the supporting rod 4111, the expansion joints at both ends can extend, so that the height of the supporting rod 4111 remains unchanged. After the concrete is poured, the movable expansion joints are locked by the solidified concrete, forming an integrated bearing structure.

[0027] like Figure 5As shown, the reinforcing cage 4 has multiple vertical bearing bars 41 evenly distributed along its circumference and corresponding rotating top support rods 42. This arrangement makes the overall stress distribution more uniform and prevents unilateral load distribution. Multiple positioning discs 43 are evenly fitted along the length of the reinforcing cage 4. Each positioning disc 43 has a first through hole 431 and a second through hole 432 corresponding to the rotating top support rod 42 and the vertical bearing bars 41, respectively. The diameter of the second through hole 432 is larger than the outer diameter of the sleeve 4113. The positioning discs 43 not only position and guide the reinforcing cage 4, the rotating top support rods 42, and the vertical bearing bars 41, but also improve the overall vertical bearing capacity by utilizing the locking action between the positioning discs 43 and the concrete. The sleeve 4113 has conical tips 4117 at both ends to facilitate guidance through the corresponding second through hole 432. The tips 4117 facilitate the sleeve 4113's entry and exit from the corresponding second through hole, preventing the sleeve 4113 from getting stuck outside the second through hole 432. The cavity 31 of the pouring channel 21 that constitutes the corresponding column 2 is cylindrical. Each layer of cement concrete hollow bricks 3 corresponds to a support unit 411 and a rotating top support unit 421 every other layer.

[0028] It should be noted that "fluidized soil" in this application refers to a material formed by adding a special curing agent to soil as raw material and then treating it. It is a fluid when poured and a solid after curing. The wall in this application is also a fluid that changes to a solid after being poured.
