Description

Technical Field

[0001] The invention relates to the field of construction equipment, and in particular to a brick formwork anti-seepage device and a construction method suitable for a part where a foundation directly contacts a soil body. Background Art

[0002] Brick formwork is widely used in foundation engineering as a basic construction measure. It is used in places such as caps, foundation beams, and basement floor side walls where the formwork cannot be removed or is difficult to remove after pouring concrete. In the traditional process, after the foundation cushion layer is poured and reaches a certain strength, a brick formwork is built to replace the formwork, and the inner side is mortared. After the brick wall reaches a certain strength, the soil on both sides is backfilled and compacted. However, for projects with large foundation areas, the existing technology has the following problems:

[0003] 1. The cost of mortar plastering and waterproofing inside the brick mold is high;

[0004] 2. The construction period of brick formwork is long;

[0005] 3. Poor anti-seepage structural strength: When pouring the inner concrete, the brick wall is prone to cracking due to uneven force, resulting in leakage;

[0006] 4. The quality consistency of brick molds is poor and is greatly affected by human factors. Summary of the invention

[0007] In order to solve the above problems, the present invention proposes a new brick formwork anti-seepage device based on traditional brick formwork construction measures, which can reduce construction costs, shorten construction period, improve anti-seepage structural strength, and have good consistency in factory modular production construction quality.

[0008] A T-shaped brick mold anti-seepage device comprises a bottom anti-seepage belt, a middle anti-seepage belt connected to the bottom anti-seepage belt and capable of being overlapped and combined layer by layer to expand the height, and a top anti-seepage belt connected to the end of the middle anti-seepage belt.

[0009] The bottom anti-seepage belt comprises a first web plate used for embedding into the horizontal brick joints of the brick formwork and an upper side wing plate fixed to the upper part of the outer edge of the web plate.

[0010] The middle anti-seepage belt includes a second web built into the horizontal brick seam of the brick formwork, an upper side wing plate fixed to the upper part of the outer edge of the second web, and a lower side wing plate fixed to the lower part of the outer edge of the second web.

[0011] The top anti-seepage belt comprises a third web which is wrapped and fixed to the top of the brick formwork, and a lower side wing which is fixed to the lower part of the outer edge of the third web.

[0012] The outer surface of the upper wing plate overlaps with the inner surface of the lower wing plate to achieve layer-by-layer overlapping and combined expansion height.

[0013] Preferably, the second web has a through hole for enhancing the connection strength between the upper and lower bricks in the horizontal brick joints of the brick mold, the through hole is circular, rectangular or polygonal, and the longest side of the through hole is less than 1.5 times the width of the second web.

[0014] Preferably, a snap-fit ​​structure for fixing and sealing is provided between the upper wing plate and the lower wing plate.

[0015] Furthermore, the outer side surface of the upper wing plate has a locking protrusion for locking, and correspondingly the inner surface of the lower wing plate has a locking groove that cooperates with the locking protrusion. The locking protrusion of the adjacent upper wing plate is locked and connected with the locking groove of the lower wing plate, which further enhances the sealing and thereby improves the anti-permeability performance.

[0016] Preferably, in order to adapt to the straight section, inner corner and outer corner positions of the brick mold, the T-shaped brick mold anti-seepage device includes a straight T-shaped brick mold anti-seepage device, an inner corner T-shaped brick mold anti-seepage device and an outer corner T-shaped brick mold anti-seepage device.

[0017] The linear T-shaped brick mold anti-seepage device includes a linear bottom anti-seepage belt, a linear middle anti-seepage belt connected to the linear bottom anti-seepage belt and capable of being overlapped and combined layer by layer to expand the height, and a linear top anti-seepage belt connected to the last stage of the linear middle anti-seepage belt.

[0018] The linear bottom anti-seepage belt comprises a first web plate for embedding into the horizontal brick joints of the brick formwork and an upper side wing plate fixed to the upper part of the outer edge of the web plate.

[0019] The linear middle anti-seepage belt includes a second web built into the horizontal brick seam of the brick formwork, an upper side wing plate fixed to the upper part of the outer edge of the second web, and a lower side wing plate fixed to the lower part of the outer edge of the second web.

[0020] The straight top anti-seepage belt comprises a third web which is wrapped and fixed to the top of the brick formwork, and a lower side wing which is fixed to the lower part of the outer edge of the third web.

[0021] The outer surface of the upper wing plate overlaps with the inner surface of the lower wing plate to achieve layer-by-layer overlapping and combined expansion height.

[0022] The linear bottom anti-seepage belt, the linear middle anti-seepage belt and the linear top anti-seepage belt are all linear profiles.

[0023] In order to adapt to the construction requirements of the inner corner of the brick mold, the linear bottom anti-seepage belt, the linear middle anti-seepage belt and the linear top anti-seepage belt are bent horizontally outward at 90 degrees on the structure to form an inner corner bottom anti-seepage belt, an inner corner middle anti-seepage belt and an inner corner top anti-seepage belt respectively. The three are combined to form an inner corner T-shaped brick mold anti-seepage device suitable for the inner corner of the brick mold.

[0024] Furthermore, the internal corner T-shaped brick mold anti-seepage device includes a internal corner bottom anti-seepage belt, a internal corner middle anti-seepage belt connected to the internal corner bottom anti-seepage belt and capable of overlapping and combining layer by layer to expand the height, and a internal corner top anti-seepage belt connected to the internal corner middle anti-seepage belt at the last stage.

[0025] In order to adapt to the construction requirements of the positive corner position of the brick mold, the linear bottom anti-seepage belt, the linear middle anti-seepage belt and the linear top anti-seepage belt are bent horizontally inward at 90 degrees on the structure to form a positive corner bottom anti-seepage belt, a positive corner middle anti-seepage belt and a positive corner top anti-seepage belt respectively. The three are combined to form a positive corner T-shaped brick mold anti-seepage device suitable for the positive corner of the brick mold.

[0026] Furthermore, the anti-seepage device of the external corner T-shaped brick mold includes a external corner bottom anti-seepage belt, a external corner middle anti-seepage belt connected to the external corner bottom anti-seepage belt and capable of overlapping and combining layer by layer to expand the height, and a external corner top anti-seepage belt connected to the final stage of the external corner middle anti-seepage belt.

[0027] Furthermore, in the T-shaped brick mold anti-seepage device as described above, the spacing between the first web and the adjacent second web, the second web and the adjacent second web, and the final second web and the third web is equal to the sum of the thickness of the brick and the thickness of the horizontal brick seam, thereby ensuring structural coordination between the anti-seepage device and the brick mold.

[0028] Preferably, the linear T-shaped brick mold anti-seepage device, the inner corner T-shaped brick mold anti-seepage device and the outer corner T-shaped brick mold anti-seepage device are made of PVC polyvinyl chloride material, which has tensile strength, ductility, low temperature characteristics, immersion resistance, chemical stability and resistance to corrosion by salt, alkali and other chemical substances.

[0029] Furthermore, the upper side wing plates of the straight T-shaped brick formwork anti-seepage device, the inner corner T-shaped brick formwork anti-seepage device and the outer corner T-shaped brick formwork anti-seepage device overlap with the adjacent lower side wing plates to form a sealing structure. Both ends of the upper side wing plates and the lower side wing plates are provided with sockets for horizontal length combination connection to ensure installation flatness. The web is buried in the mortar joint, and the plate thickness is less than or equal to the mortar joint thickness. Preferably, the plate thickness is equal to the mortar joint thickness, so that the mortar joint thickness can be effectively controlled to remain consistent and the masonry quality can be ensured. The T-shaped wing plates refer to the form of water-stop steel plates and tile-hanging roofs, overlap layer by layer and ensure that the water-facing surface faces downward, which can effectively extend the water penetration path and ensure the effectiveness of anti-seepage measures.

[0030] Furthermore, the T-shaped brick mold anti-seepage device as described above has a full-length snap-in protrusion at one end of the upper wing plate and a corresponding snap-in groove at one end of the lower wing plate. The snap-in protrusion and the snap-in groove facilitate installation and positioning while ensuring reliable connection between the upper and lower layers and increasing airtightness.

[0031] A construction method for a T-shaped brick formwork anti-seepage device comprises the following construction steps:

[0032] (1) Determine the edge and corner positions of the wall to be built according to the cushion layer elastic line, and lay the linear bottom anti-seepage strip, the positive corner bottom anti-seepage strip, and the negative corner bottom anti-seepage strip;

[0033] (2) Lay the first layer of bricks and build vertical joints. The width of the vertical joints should not exceed 10 mm and should be full, straight and smooth. The vertical joints should be filled with mortar and the horizontal joints should not be built for the time being;

[0034] (3) Lay the linear middle anti-seepage belt, the positive angle middle anti-seepage belt, and the negative angle middle anti-seepage belt, and connect the snap-in grooves of the lower wing plates and the snap-in protrusions of the upper wing plates layer by layer. Lay the horizontal joints, fill the through holes reserved in the second web with mortar, and then lay the next layer of bricks and their vertical joints until the designed height;

[0035] (4) Laying a straight top anti-seepage belt, a positive angle top anti-seepage belt, and a negative angle top anti-seepage belt, the engaging groove of the lower wing plate is engaged with the engaging protrusion of the upper wing plate adjacent to the lower side and installed in place.

[0036] The T-shaped brick mold anti-seepage device provided by the present invention has the following beneficial technical effects:

[0037] (1) Reduce construction costs: The present invention replaces the artificial plastering layer and waterproof layer, saving construction costs such as manpower and materials;

[0038] (2) Shorten the construction period: Install with masonry, complete in one go, shorten the construction period;

[0039] (3) Improve the strength of the anti-seepage structure: solve the problem of cracks in the corners of the brick wall due to uneven force during the pouring of concrete on the inner side of the traditional brick formwork construction measures, which makes the concrete prone to leakage;

[0040] (4) Good consistency in construction quality: The present invention adopts factory modular production, which avoids the influence of human factors on the construction quality and achieves good consistency in construction quality. BRIEF DESCRIPTION OF THE DRAWINGS
