Drainage channel steel mould with pull screw as drain hole

Abstract

This utility model relates to the field of railway drainage ditch construction, and particularly to a drainage ditch steel mold that uses tie rods as drainage holes. It includes a side wall mold with tie rods whose axes coincide with the designed drainage pipe hole axis. Pipe fittings are mounted on the tie rods, and the tie rods pass through the pipe fittings. After the concrete side wall is poured and formed, the pipe fittings fitted on the tie rods are embedded in the side wall, forming drainage pipe holes, thus avoiding drilling into the side wall and preventing damage to the wall structure. The tie rods limit the position of the pipe fittings, preventing positional displacement and positioning conflicts. One end of the pipe fitting abuts against the inner side plate, and the other end abuts against the outer side plate, sealing both ends of the pipe fitting and preventing concrete from entering the pipe fitting during pouring. This optimizes the construction process of the drainage pipe holes, ensures accurate positioning of the drainage pipe holes, and improves the overall construction quality of the drainage ditch.

Description

Technical Field

[0001] This utility model relates to the field of railway drainage ditch construction, and in particular to a drainage ditch steel mold in which the tie rod also serves as a drainage hole. Background Technology

[0002] Currently, the side walls of railway drainage ditches are formed by pouring concrete, and drainage pipe holes need to be installed on the poured side walls. In the current construction of cast-in-place concrete drainage ditches, either the step-by-step construction method or the pre-embedded pipe method can be used to form drainage pipe holes on the side walls. The step-by-step construction method first uses tie rods to reinforce the steel mold, and after the concrete is poured and the mold is removed, a second drilling is performed to form drainage pipe holes. The pre-embedded pipe method involves installing pre-embedded pipes inside the mold before the concrete is poured.

[0003] However, in actual construction, the step-by-step construction method requires drilling, which can easily damage the wall structure and make it difficult to guarantee the accuracy of the hole position; the pre-embedded pipe method is prone to positioning conflicts, and the pre-embedded pipe is prone to floating or shifting during the pouring and vibration process, causing deviation of the drainage pipe hole axis or even blockage. Utility Model Content

[0033] Example 1

[0034] like Figures 1-6 As shown, a drainage channel steel mold that uses tie rods as drainage holes is specifically composed of a spacing adjustment component 2 and two symmetrically arranged side wall molds 1. The two ends of the spacing adjustment component 2 are respectively connected to the side wall molds 1. The side wall mold 1 is composed of a first end plate 11, an inner side plate 14, and an outer side plate 13. The inner side plate 14 and the outer side plate 13 are spaced apart. The inner side plate 14 is detachably connected to the first end plate 11, and the outer side plate 13 is detachably connected to the first end plate 11. The first end plate 11, the outer side plate 13, the inner side plate 14, and the existing wall structure are assembled to form the frame of the side wall mold 1. Concrete is poured between the inner side plate 14 and the outer side plate 13. After solidification, the space between the three sections forms a side wall. The frame is equipped with several tie rods 3. One end of the tie rod 3 is connected to the inner side plate 14, and the other end is detachably connected to the outer side plate 13. The axis of the tie rod 3 coincides with the axis of the designed drain pipe hole. A pipe fitting 5 is provided on the tie rod 3. The tie rod 3 passes through the pipe fitting 5. After the side wall is formed, the pipe fitting 5 is embedded in the side wall, so that the pipe fitting 5 serves as a drain pipe hole. One end of the pipe fitting 5 abuts against the inner side plate 14, and the other end abuts against the outer side plate 13. During pouring, the inner side plate 14 seals the end of the pipe fitting 5, and the outer side plate 13 seals the other end of the pipe fitting 5 to avoid or reduce the entry of concrete into the pipe fitting 5.

[0035] Concrete is filled between the inner side plate 14 and the outer side plate 13. After the concrete is poured and formed, the pipe fitting 5, which is sleeved on the tie rod 3, is embedded in the side wall, so that the pipe fitting 5 forms a drainage pipe hole. This avoids drilling holes in the side wall through the step-by-step construction method, thus preventing damage to the wall. The tie rod 3 limits the position of the pipe fitting 5, preventing the pre-embedded pipe fitting 5 from shifting position and avoiding positioning conflicts. One end of the pipe fitting 5 abuts against the inner side plate 14, and the other end abuts against the outer side plate 13, so that both ends of the pipe fitting 5 are closed, which can prevent concrete from entering the pipe fitting 5 during pouring. The process of constructing the drainage pipe hole is optimized, ensuring the accurate position of the drainage pipe hole and improving the overall construction quality of the drainage channel.

[0036] When pouring concrete into a drainage ditch that has already been cast and has existing side walls, the end face of the previous side wall can be used as a pouring template. The end face of the previous side wall, the inner side plate 14, the outer side plate 13, and the first end plate 11 together form a pouring space with openings at the top and bottom. When the side wall template 1 is placed on the ground, the opening at the bottom is covered by the ground, so that the pouring space can accommodate the concrete injected from the top opening. After the concrete solidifies, the side wall is formed, so that the subsequent side wall is well connected to the previous side wall.

[0037] In an optional embodiment, the end of the pull rod 3 is detachably connected to the inner side plate 14, the pull rod 3 passes through the inner side plate 14, and abuts against the inner side plate 14 through the bolt 33 on the pull rod 3.

[0038] In one or more embodiments, the side wall mold 1 further includes a second end plate 12, with the first end plate 11 and the second end plate 12 disposed opposite to each other; the first end plate 11 is detachably connected to the outer side plate 13 and the inner side plate 14, and the second end plate 12 is detachably connected to the outer side plate 13 and the inner side plate 14; the first end plate 11, the second end plate 12, the outer side plate 13 and the inner side plate 14 are assembled to form the frame of the side wall mold 1; after the second end plate 12 is installed, the side wall mold 1 can independently cast the side wall.

[0039] In one or more embodiments, the tie rods 3 are horizontally arranged, and adjacent tie rods 3 are spaced apart. The arrangement position of the tie rods 3 is set according to the design position of the drain hole pipe.

The abutment 31 is threadedly connected to the tie rod 3 and abuts against the outer plate 13. Specifically, the abutment 31 is a nut. By tightening the nut, the tie rod 3 can be quickly installed and disassembled, which is convenient for mold assembly and disassembly. By adjusting the tightness of the nut, the inner plate 14 abuts against the end of the pipe fitting 5, and the outer plate 13 abuts against the end of the pipe fitting 5, thereby ensuring the sealing of the end of the pipe fitting 5.

[0042] In an optional embodiment, the end of the tie rod 3 is provided with a hook-shaped part 34, and the inner side plate 14 is provided with a connecting ring 7. The hook-shaped part 34 is detachably connected to the connecting ring 7. The tie rod 3 is quickly set by hooking the hook-shaped part 34 onto the connecting ring 7, so that the tie rod 3 can be quickly connected. By disassembling the tie rod 3, the space occupied is reduced, the demolding is facilitated, the risk of the tie rod 3 injuring the operator is reduced, and the safety of operation is ensured. In use, the connecting ring 7 enters the pipe fitting 5, that is, the pipe fitting 5 is required to accommodate the connecting ring 7. The angle between the hook-shaped part 34 and the tie rod 3 is less than 90 degrees, so that the hook-shaped part 34 can be firmly hooked onto the connecting ring 7.

[0043] In one or more embodiments, the bottom of the outer side plate 13 is provided with a molding mechanism 4 for anchoring and connecting to the ground. The outer side plate 13 is connected to the ground through the molding mechanism 4, and the outer side plate 13 is connected to several molding mechanisms 4 to prevent the outer side plate 13 from floating. In some embodiments, the inner side plate 14 is also connected to the molding mechanism 4 to prevent the inner side plate 14 from floating. In a specific embodiment, the first end plate 11 is bolted to the outer side plate 13 and the inner side plate 14 respectively. In an optional embodiment, the second end plate 12 is bolted to the inner side plate 14 and the outer side plate 13 respectively.

[0044] In one or more embodiments, the pipe fitting 5 includes a PVC pipe, the inner diameter of which is at least twice the outer diameter of the tie rod 3, so that the tie rod 3 can freely pass through or out of the PVC pipe; this facilitates installation by operators, and the specifications of the PVC pipe are selected according to the specifications of the designed drain hole pipe.

[0045] In one or more embodiments, a support sleeve 6 is fixedly provided on the side of the inner side plate 14 facing the pouring space; the support sleeve 6 is inserted into the pipe fitting 5; the tie rod 3 passes through the support sleeve 6, and the support sleeve 6 is embedded in the pipe fitting 5 to position the pipe fitting 5, ensuring the accuracy of the pipe fitting 5 and the sealing of the end of the pipe fitting 5; in some embodiments, a support sleeve 6 for embedding the end of the pipe fitting 5 is also provided on the outer side plate 13, so that both ends of the pipe fitting 5 are positioned and sealed, improving the positional accuracy of the pipe fitting 5 and improving the pouring quality of the side wall.

[0046] In one or more embodiments, the spacing adjustment assembly 2 includes a plurality of spacing adjustment mechanisms 21 arranged along the length of the drainage ditch. Each spacing adjustment mechanism 21 has a side wall mold 1 connected to both ends. Each spacing adjustment mechanism 21 includes a first adjustment groove 211, a second adjustment groove 212, and an adjustment element. The first adjustment groove 211 and the second adjustment groove 212 are both vertically arranged and connected to the side wall mold 1. The adjustment element consists of a first adjustment beam 213 and a second adjustment beam 214. The side wall mold 1 connected to the first adjustment groove 211 is hinged to the first adjustment beam 213, and the side wall mold 1 connected to the second adjustment groove 212... A second adjusting beam 214 is hinged, and a first adjusting beam 213 is slidably connected to a second adjusting groove 212, and a second adjusting beam 214 is slidably connected to a second adjusting groove 212; this allows the first adjusting beam 213 to slide in the second adjusting groove 212 and the second adjusting beam 214 to slide in the first adjusting groove 211, thereby changing the distance between the two side wall molds 1; specifically, a first limiting member is provided on the first adjusting beam 213, which abuts against the second adjusting groove 212 to limit the first adjusting beam 213; a second limiting member is provided on the second adjusting beam 214, which abuts against the first adjusting groove 211 to limit the second adjusting beam 214.

[0047] In an optional embodiment, the top of the molding mechanism 4 is provided with a rod, which is connected to the first adjustment groove 211 or the second adjustment groove 212, thereby connecting the inner side plate 14 to the molding mechanism 4.

[0048] It should be noted that when the inner side plate 14 or the outer side plate 13 is inclined, a pad 32 is inserted through the tie rod 3. The pad 32 adapts to the inclined surface, so that the abutting member 31 abuts against the pad 32, and then the pad 32 abuts against the inclined inner side plate 14 or the outer side plate 13.
