[0001] This utility model relates to the field of railway drainage ditch sidewall casting, and in particular to a drainage ditch steel mold with a concave-convex interlocking structure. Background Technology

[0002] When constructing a railway drainage ditch, the walls on both sides of the ditch must first be poured with concrete, followed by the bottom of the ditch. The drainage ditch is formed by enclosing it on three sides. Currently, the drainage ditch can be constructed by pouring concrete on both sides of the ditch at the same time.

[0003] However, due to the long length of the drainage ditch, it is necessary to use casting molds to construct the walls on both sides of the ditch in sections. After one section of the ditch wall is poured and solidified, the next section is moved to be poured. The two adjacent side walls are connected by post-sealing concrete, resulting in poor integrity between the two adjacent side walls and making it easy for a single section of the side wall to collapse. Utility Model Content

During demolding, the spacing between the first and second side wall formworks can be adjusted to achieve rapid demolding. When pouring the side walls, the end face of the front side wall serves as the end face of the rear side wall. The casting template of the wall allows the subsequent side wall to connect with the previous side wall after casting, thereby improving the integrity of the drainage ditch side wall. After a single side wall section is cast, a groove is formed on the end face of the side wall through the first or second protrusion. When the subsequent side wall section is cast, the concrete of the subsequent side wall section fills the groove to form a protrusion that matches the groove, thereby interlocking the adjacent side wall sections, improving the integrity of the two adjacent side wall sections, preventing the single wall section from tilting under stress, improving the overall quality of the drainage ditch after casting, and having good economic and practical value.

[0034] Example 1

[0035] like Figures 1-7As shown, a drainage ditch steel mold with an interlocking concave-convex structure is specifically composed of a first side wall mold 1, a second side wall mold 2, and a spacing adjustment component. The first side wall mold 1 and the second side wall mold 2 are arranged opposite to each other. One end of the spacing adjustment component is connected to the first side wall mold 1, and the other end is connected to the second side wall mold 2. The first side wall mold 1 is provided with a first pouring space 14, a first pouring port 16, and a first opening 15 located at the end of the first side wall mold 1. The first opening 15 and the first pouring port 16 are respectively connected to the first pouring space 14. The first protrusion 17 is provided inside the 14, and the first protrusion 17 is connected to the first side wall mold 1. The first protrusion 17 is arranged opposite to the first opening 15. The second side wall mold 2 is provided with a second pouring space 24, a second pouring port 26 and a second opening 25 located at the end of the second side wall mold 2. The second opening 25 and the second pouring port 26 are respectively connected to the second pouring space 24. The second protrusion 27 is provided inside the second pouring space 24, and the second protrusion 27 is connected to the second side wall mold 2. The second protrusion 27 is arranged opposite to the second opening 25.

[0036] Using the first side wall mold 1 and the second side wall mold 2, the side walls on both sides of the drainage ditch can be poured simultaneously. Through the spacing adjustment component, the spacing between the first side wall mold 1 and the second side wall mold 2 can be quickly adjusted, allowing the drainage ditch steel mold with its interlocking structure to adapt to drainage ditch construction of different widths. During demolding, the spacing between the first side wall mold 1 and the second side wall mold 2 can be adjusted for rapid demolding. When pouring the side walls, the end face of the front side wall serves as the pouring template for the rear side wall, connecting the rear side wall with the front side wall after pouring, thus improving the integrity of the drainage ditch side walls. After a single side wall section is poured, a groove is formed on the end face of the side wall through the first protrusion 17 or the second protrusion 27. When pouring the rear side wall section, the concrete fills the groove, forming a protrusion that matches the groove, thus interlocking adjacent side wall sections, improving the integrity of adjacent side wall sections, preventing single wall sections from collapsing under stress, and improving the overall quality of the drainage ditch after completion.

[0037] In one or more embodiments, the first sidewall mold 1 includes a first outer side plate 11, a first inner side plate 12, and a first end plate 13. The first end plate 13 is detachably connected to the first outer side plate 11 and detachably connected to the first inner side plate 12. The first outer side plate 11, the first end plate 13, and the first inner side plate 12 together form a first casting space 14. A first opening 15 is disposed opposite to the first end plate 13, and a first protrusion 17 is connected to the first end plate 13. The second sidewall mold 2 includes a second outer side plate 21. The second inner side plate 22 and the second end plate 23 are detachably connected to the second outer side plate 21 and the second inner side plate 22. The second outer side plate 21, the second end plate 23, and the second inner side plate 22 together form a second casting space 24. The second opening 25 is opposite to the second end plate 23. The second protrusion 27 is connected to the second end plate 23. The spacing adjustment assembly is connected to the first inner side plate 12 and the second inner side plate 22. The side panels 22 are parallel; after the first side wall mold 1 and the second side wall mold 2 are cast, a groove is formed on the end face of the cast side wall by the first protrusion 17 or the second protrusion 27. When the next section of the side wall is cast, the end face of the previous section of the side wall with the groove serves as the template for the tail end of the next section of the side wall. When the next section of the side wall is cast, the concrete is filled into the groove. After the next section of the side wall is formed, it extends into the groove of the previous section of the side wall, thereby improving the integrity of the adjacent side walls and preventing the collapse of a single section of the side wall. The side walls on the sides can interlock and support the middle side walls; the first end plate 13 is detachably connected to the first inner side plate 12 and the first outer side plate 11 respectively, which facilitates demolding and adjustment of the position of the first side wall mold 1; the second end plate 23 is detachably connected to the second inner side plate 22 and the second outer side plate 21 respectively, which facilitates demolding and adjustment of the position of the second side wall mold 2; the length of the first outer side plate 11 and the length of the first inner side plate 12 are both 5m; the length of the second outer side plate 21 and the length of the second inner side plate 22 are both 5m.

[0038] Specifically, the spacing adjustment assembly includes four spacing adjustment mechanisms 9, which are spaced apart. One end of each spacing adjustment mechanism 9 is connected to the first inner template and the other end is connected to the second outer template, so that the spacing between the first inner side plate 12 and the second inner side plate 22 can be adjusted. During pouring, the first inner side plate 12 and the second inner side plate 22 support each other and are parallel to each other.

[0039] In an optional embodiment, the first protrusion 17 is conical and is connected to the middle of the first end plate 13; the second protrusion 27 is conical and is connected to the middle of the second end plate 23; the first protrusion 17 and the second protrusion 27 are truncated pyramids, and in some embodiments, the first protrusion 17 and the second protrusion 27 are cones or frustums.

[0040] In an optional embodiment, the first outer side plate 11 is perpendicular to the first end plate 13, and the first inner side plate 12 is perpendicular to the first end plate 13, with the first inner side plate 12 being vertically arranged; the second outer side plate 21 is perpendicular to the second end plate 23, and the second inner side plate 22 is perpendicular to the second end plate 23, with the second inner side plate 22 being vertically arranged; the first end plate 13 is vertically arranged, and the second end plate 23 is vertically arranged; the first inner side plate 12 is vertically arranged, and the second inner side plate 22 is vertically arranged, so that the inner side of the formed drainage channel is concave, which can surround the water in the drainage channel; by making the first outer side plate 11 perpendicular to the first end plate 13 and the second outer side plate 21 perpendicular to the second end plate 23, the uniformity of the formed sidewall is ensured.

[0041] In an optional embodiment, the first inner side plate 12 is vertically arranged, the bottom of the first outer side plate 11 and the bottom of the first inner side plate 12 are spaced apart by a distance A, and the top of the first outer side plate 11 and the top of the first inner side plate 12 are spaced apart by a distance B, where distance A is greater than distance B; the second inner side plate 22 is vertically arranged, the bottom of the second outer side plate 21 and the bottom of the second inner side plate 22 are spaced apart by a distance C, and the top of the second outer side plate 21 and the top of the second inner side plate 22 are spaced apart by a distance D, where distance C is greater than distance D; the formed side wall is a side wall with a right-angled trapezoidal cross-section; due to the large pressure at the bottom of the drainage ditch, the bottom thickness of the designed cast side wall is large, so the first outer side plate 11 and the second outer side plate 21 are inclined to reduce the amount of concrete used; distance A = distance C = 1m; distance B = distance D = 0.5m.

[0042] In an optional embodiment, the first outer side plate 11 is provided with at least two first limiting beams 3, the first limiting beams 3 abutting against the first end plate 13, the first limiting beams 3 being detachably connected to the first inner side plate 12, and the first limiting beams 3 being detachably connected to the first outer side plate 11; the second outer side plate 21 is provided with at least two second limiting beams 4, the second limiting beams 4 abutting against the second end plate 23, the second limiting beams 4 being detachably connected to the second inner side plate 22, and the second limiting beams 4 being detachably connected to the second outer side plate 21; the first end plate 13 can be quickly installed and disassembled by the detachable connection and fixation of the first limiting beams 3, and the second end plate 23 can be quickly installed and disassembled by the detachable connection and fixation of the second limiting beams 4, thereby accelerating the mold assembly and disassembly, facilitating demolding and assembly, and thus speeding up the casting process; since the side wall end is embedded by the first protrusion 17 or the second protrusion 27, when disassembling the mold, the first end plate 13 and the second end plate 23 should be removed first.

[0043] Specifically, a first limiting block is provided on the first outer side plate 11, and a second limiting block is provided on the second inner side plate 22. One end of the first limiting beam 3 is tenon-jointed to the first limiting block, and the other end is tenon-jointed to the second limiting block. A third limiting block is provided on the second outer side plate 21, and a fourth limiting block is provided on the second inner side plate 22. One end of the second limiting beam 4 is tenon-jointed to the third limiting block, and the other end is tenon-jointed to the fourth limiting block. This facilitates the installation and disassembly of the first limiting beam 3 and the second limiting beam 4. When the first outer side plate 11 and the second outer side plate 21 are inclined, the first end plate 13 can avoid floating during pouring by abutting against the first limiting block, and the second end plate 23 can avoid floating during pouring by abutting against the third limiting block.

[0044] In an optional embodiment, the first outer side plate 11 is provided with a first baffle 7, which abuts against the first end plate 13; the second outer side plate 21 is provided with a second baffle 8, which abuts against the second end plate 23. The first end plate 13 is prevented from moving upward by the first baffle 7, and the second end plate 23 is prevented from moving upward by the second baffle 8, so that the first end plate 13 or the second end plate 23 can be installed quickly.

[0045] In an optional embodiment, the two ends of the first limiting beam 3 are bolted to the first inner side plate 12 and the second limiting beam 4 are bolted to the second inner side plate 22 and the second inner side plate 22, respectively.

[0046] In an optional embodiment, the first outer side plate 11 is provided with a plurality of first molding mechanisms 5, and the second outer side plate 21 is provided with a plurality of second molding mechanisms 6. The first molding mechanisms 5 are connected to the spacing adjustment assembly, and the second molding mechanisms 6 are connected to the spacing adjustment assembly. The first molding mechanisms 5 can prevent the first outer side plate 11 from floating. Since the spacing adjustment assembly is connected to the first inner side plate 12, the first molding mechanisms 5 prevent the first inner side plate 12 from floating. The second molding mechanisms 6 can prevent the second outer side plate 21 from floating. Since the spacing adjustment assembly is connected to the second inner side plate 22, the second molding mechanisms 6 prevent the second inner side plate 22 from floating.

[0047] In an optional embodiment, the spacing adjustment assembly includes four spacing adjustment mechanisms 9 arranged in an array. Each spacing adjustment mechanism 9 includes a first adjustment groove 91, a second adjustment groove 92, and an adjustment member 93. One end of the adjustment member 93 is slidably connected to the first adjustment groove 91, and the other end is slidably connected to the second adjustment groove 92. The first adjustment groove 91 is connected to the first inner side plate 12, and the second adjustment groove 92 is connected to the second inner side plate 22. A first pressing mechanism 5 is connected to the first adjustment groove 91, and a second pressing mechanism 6 is connected to the second adjustment groove 92. This prevents the first inner side plate 12 and the second inner side plate 22 from floating, allowing the adjustment member 93 to adjust the spacing between the first inner side plate 12 and the second inner side plate 22. Specifically, the adjustment member 93 includes a first adjustment beam and a second adjustment beam. One end of the first adjustment beam is hinged to the first inner side plate 12, and the other end is slidably connected to the second adjustment groove 92. Furthermore, the end of the first adjustment beam is provided with a first positioning member. The first adjusting beam abuts against the second adjusting groove 92, thereby adjusting the inclination of the first adjusting beam and thus adjusting the distance between the first inner side plate 12 and the second inner side plate 22. One end of the second adjusting beam is hinged to the second inner side plate 22, and the other end is slidably connected to the first adjusting groove 91. The end of the second adjusting beam is provided with a second positioning member, which abuts against the first adjusting groove 91, thereby adjusting the inclination of the second adjusting beam and thus adjusting the distance between the first inner side plate 12 and the second inner side plate 22. A first connecting rod is provided on the first molding mechanism 5, which is connected to the first adjusting groove 91 to fix the distance between the first outer side plate 11 and the first inner side plate 12, preventing deformation during casting. A second connecting rod is provided on the second molding mechanism 6, which is connected to the second adjusting groove 92 to fix the distance between the second outer side plate 21 and the second inner side plate 22, preventing deformation during casting.

[0048] In an optional embodiment, the first protrusion 17 is welded to the first end plate 13, and the second protrusion 27 is welded to the second end plate 23 to ensure connection strength.

[0049] This utility model discloses a drainage ditch steel mold with an interlocking concave-convex structure. When using it, during the pouring of the first section of the side wall, a shield is set at the first opening 15 and the second opening 25. The shield can be the wall at the beginning of the drainage ditch or other baffles, so that the side wall can be constructed and a groove is formed at the end of the side wall. During the pouring of subsequent side walls, the end of the previous section of the side wall is used as a template, and the concrete is embedded in the groove, so that the side walls of adjacent sections are interlocked, thereby improving the integrity of the drainage ditch side wall after pouring.
