Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a seepage-proof porous brick. Background Technology

[0002] Porous bricks on the market mainly refer to two types: concrete porous bricks and sintered porous bricks. Porous bricks have multiple vertical holes, which are perpendicular to the pressure surface during construction. When building a brick wall, any two adjacent layers of porous bricks are staggered, meaning the vertical joint between each upper layer roughly corresponds to the middle of a lower layer's porous brick, connecting the joint to one or more vertical holes on the lower layer. During construction, mortar is usually applied to the side of the porous brick and then pressed laterally against the already laid adjacent bricks, relying on pressure to fill the vertical joints. However, because of the vertical holes in the lower layer below the joint, mortar in the joint will flow into these holes under gravity, causing localized collapse of the mortar in the joint. This results in localized voids in the joint, making the mortar layer discontinuous and loose, leading to poor sealing and easy lateral leakage of rainwater.

[0003] To address the problem of vertical joint leakage, existing technologies, such as the patent with publication number CN221399554U, disclose a seepage-proof porous brick. This brick features annular grooves and retaining rings on both sides. During construction, adjacent porous bricks are quickly positioned and interlocked via the grooves and rings, ensuring a tight seal at the vertical joint and improving its seepage prevention. However, this prior art relies solely on the tight interlocking of the grooves and rings, leaving no space for mortar. Mortar must be applied to the areas outside the grooves and rings on the sides of the porous brick, directly replacing the mortar layer with the interlocking mechanism. Essentially, this provides a porous brick with a unique construction method. However, the absence of a mortar layer in the vertical joints may result in insufficient masonry strength to meet building requirements. Furthermore, the precise alignment and locking of the grooves and rings between adjacent porous bricks during construction significantly increases the difficulty for workers, is time-consuming and labor-intensive, and reduces construction efficiency. Moreover, impurities easily accumulate on the grooves or rings in the construction environment, requiring thorough cleaning to ensure precise engagement. This necessitates meticulous work by the construction workers and is unsuitable for actual building construction environments. Therefore, while existing technologies improve seepage prevention to some extent by incorporating locking rings and grooves on the sides of porous bricks, replacing the mortar layer with a locking mechanism at the vertical joints, this introduces more drawbacks. Utility Model Content

[0004] The purpose of this invention is to provide a seepage-proof porous brick that solves the problem of mortar collapse and voids easily appearing in the vertical joints between adjacent porous bricks. By setting a second base and a first base on the left and right sides of the porous brick body respectively, the first base and the second base work together to block the mortar in the vertical joint, so as to prevent the mortar from flowing down into the vertical channels of the porous brick below, thereby preventing the mortar layer in the vertical joint from collapsing and voids, and ensuring seepage prevention performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a seepage-proof porous brick, comprising a porous brick body, wherein the porous brick body has multiple vertical channels connecting the upper and lower sides, the left and right sides of the porous brick body are used to form vertical joints, a first base is provided on the right side of the porous brick body, and a second base is provided on the left side of the porous brick body. The height and left and right width of the first base and the second base are the same, and the first base and the second base are staggered in the left and right direction so that the first base and the second base together block the mortar from flowing downward in the vertical joint.

[0006] In one embodiment, the first base has an upward and horizontal first blocking surface, the second base has an upward and horizontal second blocking surface, and the first blocking surface and the second blocking surface are at the same height.

[0007] In one embodiment, the first base has a first extrusion surface that is inclined downwards away from the porous brick body, and the second base has a second extrusion surface that is inclined downwards away from the porous brick body. The first extrusion surface and the second extrusion surface are used to extrude mortar in the vertical joint at an angle downwards.

[0008] In one embodiment, the first base is located at the bottom of the right side of the porous brick body, and the second base is located at the bottom of the left side of the porous brick body, so that a partition space is formed between the first extrusion surface and the bottom of the second extrusion surface.

[0009] In one embodiment, the projection of the first base on the left side of the porous brick body along the left-right direction is connected to the second base in front and behind, so that the first base and the second base in the same vertical seam are spliced ​​together in front and behind.

[0010] In one embodiment, the projection of the first base on the left side of the porous brick body along the left-right direction forms a gap channel with the second base at a front-to-back interval, so that the gap channel can be filled with mortar layer.

[0011] In one embodiment, the porous brick body has a plurality of vertical channels arranged in a front-to-back pattern in the middle, and the spacer channels and the vertical channels in the middle of the porous brick are staggered in the left-right direction.

[0012] In one embodiment, a first protrusion located above the first base is provided on the right side of the porous brick body, and a second protrusion located above the second base is provided on the left side of the porous brick body. The front-to-back length of the first protrusion and the second protrusion are the same as that of the porous brick body, and the left-to-right width is smaller than that of the first base. The first protrusion is higher than the second protrusion, so that a flow gap is formed between the first protrusion and the second protrusion.

[0013] The advantages of this application compared to the prior art are:

[0014] In this embodiment, the first base on the right side of the porous brick body and the second base on the left side are staggered in the left-right direction. Therefore, when two adjacent porous bricks are laid together, there are a first base and a second base in the vertical joint between them. For example, the first base is located at the front of the vertical joint and the second base is located at the rear of the vertical joint. The staggered arrangement of the two bases prevents the mortar from flowing downward at the front of the vertical joint and the second base prevents the mortar from flowing downward at the rear of the vertical joint. This together blocks the mortar in the vertical joint, preventing the mortar in the vertical joint from flowing downward into the vertical channels of the porous brick below. This prevents voids in the mortar layer in the vertical joint and improves the seepage prevention ability at the vertical joint. Attached Figure Description

[0028] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0029] Please refer to Figure 1 This is a three-dimensional structural diagram of a waterproof porous brick wall constructed according to an embodiment of this application.

[0030] like Figure 1As shown in the illustration, an embodiment of this application discloses a seepage-proof porous brick, comprising a porous brick body 100. The porous brick body 100 is generally rectangular in shape and has six external surfaces. This specification describes the seepage-proof porous brick in its construction posture. The porous brick body 100 has multiple vertical channels 110 connecting the upper and lower surfaces, while the left and right sides of the porous brick body 100 are used to form vertical joints 200. When constructing the brick wall, it is laid layer by layer from bottom to top. The upper surface of the lower layer of porous bricks is coated with mortar. The porous brick to be laid is placed on the lower layer of porous bricks and the mortar below is squeezed, allowing some mortar to enter the vertical channels 110. At the same time, the left or right side of the porous brick forms a vertical joint 200 with the side of the adjacent porous brick in the same layer, jointly squeezing the mortar to form a mortar layer in the vertical joint 200. Each layer of porous bricks is arranged in the left-right direction. Adjacent porous bricks in the same layer form vertical joints 200 through the left and right sides. The porous bricks of two adjacent layers are staggered, that is, each vertical joint 200 corresponds to the middle part of a porous brick directly below. Once the vertical channel 110 in the middle part of the porous brick corresponds to the vertical joint 200 in whole or in part, the mortar in the vertical joint 200 may flow into the vertical channel 110 under the action of gravity, causing local holes in the mortar layer in the vertical joint 200.

[0031] Please refer to Figure 1 The difference between this embodiment and the prior art is that the porous brick body 100 in this embodiment is provided with a first base 310 on the right side and a second base 320 on the left side. The height and left and right width of the first base 310 and the second base 320 are the same, and the first base 310 and the second base 320 are staggered in the left and right direction so that the first base 310 and the second base 320 jointly block the mortar from flowing downward in the vertical joint 200. In this embodiment, the first base 310 on the right side of the porous brick body 100 and the second base 320 on the left side are staggered in the left-right direction. Therefore, when two adjacent porous bricks are laid together, there are a first base 310 and a second base 320 in the vertical joint 200 between them. For example, the first base 310 is located at the front of the vertical joint 200, and the second base 320 is located at the rear of the vertical joint 200. The staggered arrangement of the two bases prevents the mortar from flowing downward at the front of the vertical joint 200 and the second base 320 from flowing downward at the rear of the vertical joint 200. This together achieves the blocking of the mortar in the vertical joint 200, preventing the mortar in the vertical joint 200 from flowing downward into the vertical channel 110 of the porous brick below, thereby preventing voids in the mortar layer in the vertical joint 200 and improving the seepage prevention ability at the vertical joint 200.

[0032] Furthermore, in this embodiment, the first base 310 and the second base 320 are at the same height. Therefore, the first base 310 and the second base 320, which intersect each other in the same vertical joint 200, block the mortar at the same height. On the one hand, this avoids the gap caused by the height difference between them, preventing the mortar from flowing down through the gap between the first base 310 and the second base 320, thus improving the blocking effect on the mortar. On the other hand, it allows the mortar above the first base 310 and the second base 320 to be evenly distributed, improving the bonding strength and seepage prevention performance. If the left and right widths of the first base 310 and the second base 320 are different, for example, the former is larger than the latter, then when the first base 310 abuts against the side of the adjacent porous brick during construction, the second base 320 on the adjacent porous brick cannot abut against the side of the porous brick where the first base 310 is located, resulting in a gap. This causes the second base 320 to not completely block the mortar, allowing the mortar to flow down through the gap. Therefore, in this embodiment, the left and right widths of the first base 310 and the second base 320 are the same, so that during the masonry process, the first base 310 and the second base 320 in the same vertical joint 200 can completely block the mortar above them, thereby improving the blocking effect on the mortar and further preventing the mortar from flowing downward.

[0033] Please refer to Figure 2 Preferably, in this embodiment, the first base 310 has an upward-facing and horizontal first blocking surface 311, and the second base 320 has an upward-facing and horizontal second blocking surface 321, with the first blocking surface 311 and the second blocking surface 321 at the same height. The first base 310 blocks the mortar above it through the horizontally upward-facing first blocking surface 311, and the second base 320 blocks the mortar above it through the horizontally upward-facing second blocking surface 321. Therefore, the first blocking surface 311 and the second blocking surface 321 are set at the same height, making the mortar above them evenly distributed. Furthermore, the horizontal setting of the first blocking surface 311 and the second blocking surface 321 ensures that the mortar is evenly distributed on both sides, further improving the adhesion and seepage prevention performance of the mortar layer in the vertical joint 200.

[0034] Preferably, the first base 310 has a first pressing surface 312 that is inclined downwards from the porous brick body 100, and the second base 320 has a second pressing surface 322 that is inclined downwards from the porous brick body 100. The first pressing surface 312 and the second pressing surface 322 are used to press the mortar in the vertical joint 200 downwards at an angle. During construction, the porous bricks being constructed are pressed laterally to the left and right of adjacent constructed porous bricks to form vertical joints 200 between them. Before construction, mortar is usually applied to the side of one of the porous bricks, and then the mortar is pressed into the vertical joint 200 during the lateral pressing process to form a mortar layer. In this embodiment, the first base 310 has a first extrusion surface 312, and the second base 320 has a second extrusion surface 322. The first extrusion surface 312 and the second extrusion surface 322 are respectively inclined in the direction away from the porous brick body 100. Therefore, when the two porous bricks are laterally extruded into mortar, the first extrusion surface 312 and the second extrusion surface 322 both move laterally towards the mortar and extrude mortar at an angle. This can reduce the resistance of the lateral movement of the porous bricks during construction, making it easier for construction workers. It can also fill the bottom of the first base 310 and the second base 320 with mortar, so that the top and bottom of the first base 310 and the second base 320 are bonded by mortar, further improving the bonding force between adjacent porous bricks.

[0035] In this embodiment, the presence of the first base 310 and the second base 320 divides the mortar layer in the vertical joint 200 into an upper mortar layer and a lower mortar layer. The first base 310 and the second base 320 block the upper mortar layer above them to prevent mortar from flowing downward into the vertical channels 110 of the porous brick below. However, the lower mortar layer below the first base 310 and the second base 320 will still flow into the vertical channels 110 of the porous brick below under the action of gravity, resulting in collapsed holes in the lower mortar layer. Therefore, further, in this embodiment, the first base 310 is located at the bottom of the right side of the porous brick body 100, and the second base 320 is located at the bottom of the left side of the porous brick body 100, so that a partition space 410 is formed below the first extrusion surface 312 and the second extrusion surface 322. On the one hand, the first base 310 and the second base 320 are both located at the bottom, which can increase the vertical thickness of the upper mortar layer and reduce the vertical thickness of the lower mortar layer, that is, reduce the amount of mortar in the lower mortar layer. In this way, even if some mortar in the lower mortar layer flows down into the vertical channels 110 of the porous brick below, the negative impact on the lower mortar layer is also small. Furthermore, in this embodiment, the first extrusion surface 312 of the first base 310 is inclined towards the mortar, and the second extrusion surface 322 of the second base 320 is also inclined towards the mortar. The partition space 410 formed below the first extrusion surface 312 and the second extrusion surface 322 is used to accommodate the lower mortar layer. Compared with the horizontal setting, the height of the partition space 410 can be increased. In this way, when local collapse and voids occur in the lower mortar layer, it is convenient to replenish mortar from the front and rear outlets of the partition space 410 to fill the voids in the lower mortar layer and ensure the adhesion and seepage prevention performance of the lower mortar layer.

[0036] Please refer to Figure 3In this embodiment, the first base 310 and the second base 320 on the porous brick body 100 are staggered in the left-right direction, so that the first base 310 and the second base 320 located in the same vertical joint 200 are arranged one after the other to jointly block the mortar in the vertical joint 200. Further, in one embodiment of this application, the projection of the first base 310 on the left side of the porous brick body 100 in the left-right direction is connected to the second base 320, so that the first base 310 and the second base 320 in the same vertical joint 200 are joined together. Thus, there is no obvious gap between the first base 310 and the second base 320 in the same vertical joint 200 (including the case where there is a small amount of mortar between them resulting in a slight gap of 0-5 mm), and they are roughly in a state of mutual contact, preventing the blocked mortar from flowing downwards between the first base 310 and the second base 320, thereby improving the mortar blocking effect. In the previous embodiment, the first base 310 and the second base 320 are generally in a state of mutual abutment, including the case where mortar with a front-to-back thickness of 0-5 mm is sandwiched between them. This is because during actual construction and mortar application, some mortar may inevitably adhere to the opposing sides of the first base 310 and the second base 320, or some mortar may be squeezed between the first base 310 and the second base 320 during the process of squeezing the mortar in the vertical joint 200. However, the amount of mortar appearing between the first base 310 and the second base 320 is very small, usually only 0-5 mm in front-to-back thickness. Therefore, even if it exists, it is difficult for it to flow downwards and can be stably sandwiched between the first base 310 and the second base 320. Thus, this situation is also considered as the state of the first base 310 and the second base 320 being spliced ​​together.

[0037] In another embodiment of this application, the projection of the first base 310 along the left-right direction on the left side of the porous brick body 100 forms a gap joint 420 with the second base 320 at a front-to-back interval, so that the gap joint 420 can be filled with a mortar layer. In this embodiment, the first base 310 and the second base 320 have a significant front-to-back gap to form the gap joint 420, for example, the front-to-back width is greater than 5 mm. During construction, mortar can be directly applied to the opposing sides of the first base 310 and the second base 320. After construction, the first base 310 and the second base 320 compress the mortar in the gap joint 420, so that a mortar layer is also formed in the gap joint 420. By increasing the bonding force between the first base 310 and the second base 320, the bonding strength between adjacent porous bricks is improved. Furthermore, the first base 310 and the second base 320 are integrally formed with the porous brick body 100 and are made of the same material. The first base 310 and the second base 320 are arranged one in front of the other, which is the inside and the outside of the brick wall. The mortar layer in the gap channel 420 separates the first base 310 and the second base 320. When the outside of the wall comes into contact with water, for example, when the outer first base 310 absorbs water, the mortar layer in the gap channel 420 can prevent the water in the first base 310 from continuing to flow to the second base 320, thereby improving the water-proofing ability.

[0038] However, in embodiments where a spacer channel 420 exists between the first base 310 and the second base 320, if the spacer channel 420 corresponds precisely to the vertical channel 110 of the porous brick below, the mortar in the vertical channel 110 is relatively abundant and, under gravity, easily flows downwards into the vertical channel 110, causing collapse and voids in the mortar layer. Therefore, for further improvements, please refer to... Figure 4 In this embodiment, the porous brick body 100 has multiple vertical channels 110 arranged in a front-to-back pattern in its middle section. The spacer joint 420 and the vertical channels 110 in the middle of the porous brick are staggered in the left-right direction. For the same porous brick, the projections of its vertical channels 110 on the left and right sides in the left-right direction do not coincide with the spacer joint 420. Thus, the spacer joint 420 will not correspond to the vertical channels 110 of the porous brick below it, thereby preventing the mortar layer in the spacer joint 420 from collapsing and creating holes, and ensuring water-proof performance.

[0039] Please refer to Figure 5-8Preferably, in one embodiment of this application, a first protrusion 510 located above the first base 310 is provided on the right side of the porous brick body 100, and a second protrusion 520 located above the second base 320 is provided on the left side of the porous brick body 100. The front-to-back length of the first protrusion 510 and the second protrusion 520 are consistent with the porous brick body 100, and the left-to-right width is smaller than the left-to-right width of the first base 310. The first protrusion 510 is higher than the second protrusion 520, so that a flow gap 530 is formed between the first protrusion 510 and the second protrusion 520. In this embodiment, when two adjacent perforated bricks are laid together, in the vertical joint 200, the first protrusion 510 on the left perforated brick has a right-side gap with the side of the right perforated brick, and the second protrusion 520 on the right perforated brick has a left-side gap with the side of the left perforated brick. The right-side gap and the left-side gap are misaligned vertically. Furthermore, the first protrusion 510 and the second protrusion 520 form a flow gap 530 between them due to their height difference. Therefore, the first protrusion 510 and the second protrusion 520 play a certain role in hindering the mortar, allowing more mortar to adhere near the first protrusion 510 and the second protrusion 520, reducing the downward flow of mortar, and improving the uniformity of the mortar layer in the vertical joint 200.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
