Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a precast slab structure for foundation formwork. Background Technology

[0002] Traditional brick formwork is a method of using brick masonry instead of wooden or steel formwork for support, mainly used in places where side formwork is difficult to remove, such as basement foundations and pile caps.

[0003] However, large-scale brick formwork construction involves a large amount of work, requiring significant manpower and resources. The next construction process can only proceed after the mortar strength has reached a certain level, resulting in a long construction period, high costs, and the low strength of the brick formwork, which can easily lead to cracks and collapses during backfilling around the foundation. Summary of the Invention

[0004] To address the aforementioned shortcomings in existing technologies, this utility model provides a precast slab structure for foundation formwork, which solves the problems of large-scale brick formwork construction, requiring significant manpower and resources, and the need to wait for the mortar to reach sufficient strength before proceeding to the next construction step, resulting in a long construction cycle.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A precast slab structure for a basic mold includes a first precast slab, which is vertically arranged and has a first groove along its centerline on its top surface and symmetrical slots about the centerline axis; a second precast slab, on which a first protrusion is fixedly installed along its centerline on its bottom surface and is vertically arranged and installed on the top surface of the first precast slab; and a sealing plate, the two ends of which are adapted to the first groove and the first protrusion, respectively; the first and second precast slabs are connected as a whole by the sealing plate, and the sealing plate has symmetrically arranged positioning holes, which are inclined.

[0006] In this way, when assembling the mold of the foundation, the first precast plate is placed vertically on the pre-leveled pad, the sealing plate is placed by aligning the end face of the first groove with the first precast plate, and then the second precast plate is placed with the sealing plate to complete the assembly of the mold. Specifically, the first and second precast plates are made by pre-mixing fibers with cement, aggregates (perlite, ceramsite, slag) and water into a mixture, and then extruding, hollowing and vibrating to make a porous plate. After the first and second precast slabs are connected into a whole by the sealing plate, positioning steel bars are inserted into the positioning holes to strengthen the connection between the first and second precast slabs. This structure can shorten the construction cycle of the foundation formwork, improve the flexural strength and impact strength of the formwork, and thus reduce the possibility of cracks and collapses during backfilling around the foundation.

[0007] Furthermore, the top surface of the sealing plate has a second groove that matches the first protrusion. The bottom surface of the sealing plate has a second protrusion that matches the first groove. The bottom surface of the sealing plate has a symmetrically fixed locking block that matches the locking groove. Thus, the first precast slab and the second precast slab can form a stable whole through the sealing plate, reducing the area that workers need to plaster and thus reducing the workload of workers.

[0008] Furthermore, the surface of the second groove is provided with diagonal lines, which can reduce the possibility of relative slippage between the sealing plate and the second precast plate.

[0009] Furthermore, metal tie rods are used to fix the transverse connection between the first and second precast slabs, which can improve the stability of the transverse connection and make it easier to control the gap width at the transverse connection.

[0010] Furthermore, anti-crack strips are fixedly installed on both sides of the connection between the first and second precast slabs, which can ensure the flatness of the top and improve the overall integrity of the precast slab structure.

[0011] Furthermore, the sealing plate is bonded to the first precast plate and the second precast plate with cement glue, which can enhance the stability of the connection and facilitate subsequent processes.

[0012] Furthermore, the first precast slab has drainage holes evenly spaced on its side, which facilitates the drainage of water accumulated within the foundation mold and improves the stability of the foundation. Attached Figure Description

[0014] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0016] Example 1: like Figures 1-4 As shown, this utility model discloses a precast plate structure for a basic mold, comprising: a first precast plate 1, which is vertically arranged, with a first groove 101 along the centerline on the top surface of the first precast plate 1 and symmetrical slots 102 about the centerline axis on the top surface of the first precast plate 1; a second precast plate 2, with a first protrusion 201 fixedly installed on the bottom surface of the second precast plate 2 along the centerline, and the second precast plate 2 is vertically arranged and installed on the top surface of the first precast plate 1; and a sealing plate 3, with its two vertical end faces respectively adapted to the first groove 101 and the first protrusion 201; the first precast plate 1 and the second precast plate 2 are connected as a whole by the sealing plate 3, and the sealing plate 3 has symmetrically arranged positioning holes 301, which are inclined.

[0017] Thus, when assembling the mold of the foundation, the first precast plate 1 is placed vertically on the pre-leveled pad, the sealing plate 3 is placed with its end face that is adapted to the first groove 101 aligned with the first precast plate 1, and then the second precast plate 2 is placed aligned with the sealing plate 3 to complete the assembly of the mold. Specifically, the first precast plate 1 and the second precast plate 2 are porous plates made by pre-mixing fiber with cement, aggregate (perlite, ceramsite, slag) and water into a mixture, and then extruding, hollowing, and vibrating to form a porous plate. After the first precast slab 1 and the second precast slab 2 are connected into a whole by the sealing plate 3, the positioning steel bars are inserted into the positioning hole 301 to strengthen the connection between the first precast slab 1 and the second precast slab 2. With this structure, the construction cycle of the foundation formwork can be shortened, the flexural strength and impact strength of the formwork can be improved, and the possibility of cracks and collapse during backfilling around the foundation can be reduced.

[0018] The top surface of the sealing plate 3 has a second groove 302, which is adapted to the first protrusion 201. The bottom surface of the sealing plate 3 has a second protrusion 303, which is adapted to the first groove 101. The bottom surface of the sealing plate 3 has a symmetrically fixed locking block 304, which is adapted to the locking groove 102. Thus, the first precast slab 1 and the second precast slab 2 can form a stable whole through the sealing plate 3, reducing the area that workers need to plaster, thereby reducing the workload of workers.

[0019] The surface of the second groove 302 is provided with diagonal lines 4, which can reduce the possibility of relative slippage between the sealing plate 3 and the second precast plate 2.

[0020] Metal tie rods are used to fix the transverse connection of the first precast slab 1 and the second precast slab 2, which can improve the stability of the transverse connection and make it easier to control the width of the seam at the transverse connection.

[0021] Crack-resistant strips are fixedly installed on both sides of the connection between the first precast slab 1 and the second precast slab 2. Specifically, the crack-resistant strips on the sides of the first precast slab 1 and the second precast slab 2 are installed with the non-cut surface of the mesh cloth facing upwards, which can ensure the flatness of the top and improve the overall integrity of the precast slab structure.

[0022] The sealing plate 3 is bonded to the first precast plate 1 and the second precast plate 2 with cement glue, which can enhance the stability of the connection and facilitate subsequent processes.

[0023] The first precast slab 1 has drainage holes 5 evenly spaced on its side, which facilitates the drainage of water accumulated in the foundation mold and improves the stability of the foundation.

[0024] Example 2: like Figures 5-7 As shown, the other features of Example 2 are the same as those of Example 1, except that: The first precast slab 1 has a first groove 101 along the centerline on one end face and a slot 102 symmetrically formed about the centerline axis on the other end face; the second precast slab 2 has a first protrusion 201 fixedly installed on one end face along the centerline and is perpendicular to the first precast slab 1; the sealing plate 3 has vertical end faces that abut against the first groove 101 and the side of the second precast slab 2 respectively; the first precast slab 1 and the second precast slab 2 are connected as a whole by the sealing plate 3, and the sealing plate 3 has symmetrically formed positioning holes 301, which are inclined.

[0025] In this way, the sealing plate 3 is aligned and connected to the first precast plate 1 through the second protrusion 303 and the locking block 304. The end face of the sealing plate 3 with the second groove 302 abuts against the side of the second precast plate 2. Specifically, the second groove 302 and the side of the second precast plate 2 are bonded together with cement glue. The surface of the second groove 302 is provided with diagonal lines 4, which can simulate the surface after roughening and further improve the stability of the cement glue bonding. With this structure, the first precast plate 1 can be vertically connected to the second precast plate 2, which improves the applicability of this precast plate structure.
