[0036] The guide groove 13 is provided on the outer peripheral surface of the connector 1 and is located between the first connection part 11 and the second connection part 12 in the axial direction. The guide groove 13 is used to guide the destruction to separate the first connection part 11 and the second connection part 12, thereby separating the first connection member and the second connection member.

[0037] The connecting piece of the embodiment of the utility model can connect the first connecting member and the second connecting member, and when disassembling, the guide groove guides the destruction, so that the first connecting part and the second connecting part are separated, and then the first connecting member and the second connecting member are separated, and the separation process is not easy to damage the connecting member. The connecting piece of the embodiment of the utility model is disposable, and the connecting members on both sides can be quickly disassembled after being destroyed. After cleaning the damaged connecting piece, it can be connected and used again, which reduces the construction complexity of disassembly and reconnection, and is convenient and quick.

[0038] Optionally, the connector 1 is a plastic connector, that is, the connector 1 is made of plastic, for example, a polymer material is used to manufacture the connector 1 by an integral injection molding process. Connectors made of plastic have low cost, simple process, and are easy to break.

[0039] In some embodiments, in order to facilitate connection with the first connecting member and the second connecting member, the outer circumference of at least one of the first connecting portion 11 and the second connecting portion 11 is provided with an external thread. Correspondingly, the first connecting member and the second connecting member may be provided with an internal threaded hole. Optionally, the outer circumference of the first part 11 of the connector 1 is provided with an external thread, and is threadedly connected to the internal threaded hole of the first connecting member, and optionally, the outer circumference of the second part 12 of the connector 1 is provided with an external thread, and is threadedly connected to the internal threaded hole of the second connecting member.

[0040] In some optional embodiments, such as Figure 1 As shown, the cross section of the guide groove 13 of the connecting member 1 is triangular, and the width of the guide groove 13 gradually increases from the inside to the outside along the radial direction of the connecting member 1.

[0041] In some optional embodiments, such as Figure 3 As shown, the cross section of the guide groove 13 of the connecting member 1 is rectangular, and the width of the guide groove 13 is the same from the inside to the outside along the radial direction of the connecting member 1.

[0042] In some optional embodiments, such as Figure 4 As shown, the cross section of the guide groove 13 of the connecting member 1 is trapezoidal, and the width of the guide groove 13 gradually increases from the inside to the outside along the radial direction of the connecting member 1.

[0043] In some embodiments, the guide groove 13 of the connector 1 is annular, and the guide groove 13 extends along the circumference of the connector 1, surrounding the outer peripheral surface of the connector 1. The annular guide groove 13 is arranged around the outer peripheral surface of the connector 1, and the position where the connector 1 is provided with the guide groove 13 is a breakable position, and the first connector 11 and the second connector 12 are easier to separate. It can be understood that the radius of the position of the connector 1 corresponding to the guide groove 13 is smaller than the radius of the first connector 11 and the radius of the second connector 12.

[0044] Optionally, the outer circumferential surface of the connector 1 is provided with a plurality of annular guide grooves 13, which are arranged in sequence in the axial direction of the connector 1. When the first connecting member and the second connecting member are disassembled, any of the plurality of guide grooves 13 can guide the breakage.

[0045] As an example, Figure 1 As shown, the outer circumferential surface of the connecting member 1 is provided with a first guide groove 131 and a second guide groove 132 . The first guide groove 131 and the second guide groove 132 are both annular and are arranged at intervals in the axial direction of the connecting member 1 .

[0046] In other embodiments, the outer circumferential surface of the connector 1 is provided with a plurality of guide grooves 13, wherein at least some of the guide grooves 13 are arranged at intervals around the circumference of the connector 1. For example, the outer circumferential surface of the connector 1 is provided with a first guide groove and a second guide groove, the first guide groove and the second guide groove are opposite in the radial direction of the connector 1, and when disassembling, the connector 1 is broken at the positions corresponding to the first guide groove and the second guide groove, so that the first connection part 11 and the second connection part 12 are separated.

[0047] In some embodiments, Figure 5 As shown, the connector 1 further includes a baffle 14, which is located between the first connecting portion 11 and the second connecting portion 12 in the axial direction of the connector 1. When assembled, the baffle 14 is located between the first connecting member and the second connecting member, and the first side of the baffle 14 abuts against the first connecting member, and the second side of the baffle 14 abuts against the second connecting member. The baffle 14 is used to limit and position the cooperation between the connector 1 and the first connecting member, and between the connector 1 and the second connecting member. Figure 5 As shown, the outer circumference of the baffle 14 is located outside the outer circumference of the first connecting portion 11 and the second connecting portion 12 .

[0048] In order to facilitate the separation of the first connection portion 11 from the first connection member, and to facilitate the separation of the second connection portion 12 from the second connection member, in some embodiments, as Figure 2 As shown, the middle part of the connecting member 1 is provided with a through hole 15 extending along the axial direction of the connecting member 1, and the cross section of the through hole 15 is a polygon. After the first connecting portion 11 and the second connecting portion 12 are separated, a tool can be inserted into the through hole 15 of the first connecting portion 11 to quickly separate the first connecting portion 11 from the first connecting member, and a tool can be inserted into the through hole 15 of the second connecting portion 12 to quickly separate the second connecting portion 12 from the second connecting member.

[0049] Alternatively, if Figure 2 As shown, the cross section of the through hole 15 is hexagonal, and after the destruction, the first part 11 and the second part 12 are taken out using a hexagonal wrench. It can be understood that the through hole 15 can also be a shape corresponding to other commonly used wrench structures.

[0050] In some embodiments, in order to facilitate the assembly of the connecting member 1 with the first connecting member and the second connecting member, the edges of the two opposite ends of the connecting member 1 in the axial direction are both chamfered.

[0051] like Figure 1 As shown, the first part 11 has a first end and a second end opposite to each other in the axial direction of the connecting member 1, and the second part 12 has a first end and a second end opposite to each other in the axial direction of the connecting member 1, the first end of the first part 11 is a free end, the second end of the first part 11 is connected to the first end of the second part 12 and a guide groove 13 is provided therebetween, the second end of the second part 12 is a free end, the edge of the first end of the first part 11 is chamfered, and the edge of the second end of the second part 12 is chamfered.

[0052] In some embodiments, the first connection portion 11 and the second connection portion 12 of the connection member 1 are symmetrical with respect to the guide groove 13 , so that the structure of the connection member 1 is more reasonable and the forces on the first connection portion 11 and the second connection portion 12 are more balanced.

[0053] The connector 1 of the utility model can be used in a concrete casting mold to cast and manufacture concrete pipe segments. Figure 6-Figure 11 As shown, the concrete casting mold 100 of the present invention comprises a bottom mold 2 and a plurality of connecting members, wherein the connecting members are the connecting members 1 of any one embodiment of the present invention.

[0054] The upper surface of the bottom mold 2 is provided with a plurality of connection holes 21 at intervals, and the connector 1 corresponds to the connection holes 21 one by one. The first connection portion 11 extends upward to be connected to the inserted rib 3 located above the bottom mold 2, and the second connection portion 12 extends downward into the corresponding connection hole 21 and is connected to the bottom mold 2. The guide groove 13 provided on the outer peripheral surface of the connector 1 has a relatively weak structural strength. When disassembling the mold, the connector 1 is split from the guide groove 13, and the first connection portion 11 is separated from the second connection portion 12, thereby separating the inserted rib 3 from the bottom mold 2, thereby realizing rapid disassembly of the mold. In other words, the first connection member is the inserted rib 3, and the second connection member is the bottom mold 2.

[0055] Since the mold needs to be disassembled and reassembled after each casting of the pipe segment, and the tower mold is often huge in size and complex in structure, conventional bolts are usually used to connect the assembly joints of the mold in the related technology, but the operation is inconvenient due to insufficient operating space, and there are also problems such as low production efficiency and high cost.

[0056] The concrete pouring mold of the embodiment of the utility model can be used for pouring and producing concrete tower segments. Before pouring, the inserted rebar is connected to the bottom mold by a connecting piece, so that the inserted rebar can be positioned relative to the bottom mold. During the grouting and pouring process, the accuracy of the pre-embedded inserted rebar and the pouring stability are effectively guaranteed. When the mold is removed, the connecting piece breaks at the guide groove, and the first connecting part and the second connecting part of the connecting piece are separated, so that the bottom mold can be quickly separated from the inserted rebar.

[0057] The concrete casting mold of the embodiment of the utility model utilizes a connecting piece to connect the dowel bar to the bottom mold. The connecting piece has extremely low requirements for operating space, which greatly improves the operational efficiency of disassembly and reassembly of the concrete tower mold, thereby improving the efficiency of concrete pipe segment production.

The connection hole 21 is a threaded hole, and the second connection portion 12 of the connector 1 is threadedly connected to the corresponding connection hole 21.

[0060] Specifically, Figure 6-Figure 11As shown, the upper part of the dowel sleeve 2 is sleeved with the bottom of the dowel 3, and the lower part of the dowel sleeve 2 extends downward, and the inner circumference is provided with an internal thread. The outer circumference of the first connecting portion 11 of the connector 1 is provided with an external thread.

[0063] When assembling the bottom mold 2, the threaded sleeve 23 is inserted downward into the corresponding through hole 221 on the bottom mold panel 22, so that the bottom of the threaded sleeve 23 extends downward from the through hole 221, and the threaded sleeve 23 is welded to the bottom mold panel 22 below the bottom mold panel 22. For example, the threaded sleeve 23 is welded to the bottom mold panel 22 using a fillet weld intermittent welding process to facilitate the replacement of the threaded sleeve 23 later.

[0064] like Figure 8 and Fig.11 As shown, in order to facilitate the assembly of the threaded sleeve 23, the bottom of the threaded sleeve 23 is provided with a chamfer.

[0065] Furthermore, in order to facilitate the separation of the bottom mold 2 and the inserted rib 3, as Figure 7 and Fig.10 As shown, the top surface of the threaded sleeve 23 is flush with the top surface of the bottom mold panel 22.

[0066] In other embodiments, the bottom mold panel 22 and the threaded sleeve 23 are an integral structure.

[0067] In some embodiments, Figure 8 and Fig.11As shown, the connector 1 further includes a baffle 14, which is located between the first connector 11 and the second connector 12 in the axial direction of the connector 1, the lower surface of the baffle 14 abuts against the bottom mold 2, and the upper surface of the baffle 14 abuts against the reinforcing bar sleeve 2. The baffle 14 is used to limit and position the cooperation between the first connector 11 and the threaded sleeve 23, and the baffle 14 is also used to limit and position the cooperation between the second connector 12 and the reinforcing bar sleeve 2.

[0070] In some embodiments, Figure 6-Figure 11 As shown, the concrete casting mold 100 also includes a sealing gasket 5, which is clamped between the rebar sleeve 2 and the bottom mold 2. The sealing gasket 5 effectively seals the joint between the rebar sleeve 2 and the bottom mold 2 to prevent the slurry from flowing in during grouting and facilitates the destruction of the connecting piece 1 and the demoulding of the bottom mold 2 during disassembly.

[0071] According to the following Figure 6-Figure 11 A concrete pouring mold 100 in a specific embodiment of the present invention is described.

[0072] exist Figure 6-Figure 8In the illustrated embodiment, the bottom mold 2 includes a bottom mold panel 22 and a plurality of threaded sleeves 23.
