Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction, and in particular to a positioning fixture for thin-walled concrete revetment construction. Background Technology

[0002] When producing thin-walled concrete or cement products such as parapets, pipes, and covers, steel wires or reinforcing bars (usually only one layer of smaller diameter wires or bars is placed in the center) need to be laid in the formwork according to the design drawings. Because these products have thin walls, mostly between 15 and 50 mm, and the reinforcement is relatively fine, it is not convenient to place cement mortar or other positioning blocks in the formwork in the traditional way. Therefore, it is difficult to guarantee the position of the steel wires or reinforcing bars during casting, which in turn affects the quality of the finished product.

[0003] Utility model patent CN210500793U discloses a steel wire positioning clamp, but when the steel wire is inserted into the clamp's slot, the steel wire is prone to detaching from the slot because the slot is not an open structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a positioning clamp for thin-walled concrete masonry construction, which solves the problem that the steel wire is easy to fall out when it is inserted into the groove.

[0005] To solve the above-mentioned technical problems, this utility model provides a positioning clamp for thin-walled concrete revetment construction, including a clamp body, a groove extending radially from the outer wall to the center of the clamp, a through hole connecting to the groove at the center of the clamp, and a fixing device for fixing steel wire at the through hole.

[0006] In a preferred embodiment, a circular first groove is provided along the length of the through hole, and the fixing device is disposed within the first groove.

[0007] In a preferred embodiment, the fixing device includes a guide rail disposed on the first groove and a movable locking rod disposed on the guide rail. The locking rod can be moved to lock the connection between the through hole and the groove, preventing the steel wire from falling out.

[0008] In the preferred embodiment, the guide rail is circular and coaxial with the through hole. A notch larger than the slot is provided on one side of the guide rail, and the position of the notch coincides with the position of the slot.

[0009] In the preferred embodiment, the lever is also circular, and the overlapping part of the lever and the guide rail is larger than the size of the notch.

[0010] In the preferred embodiment, the lever is made of plastic.

[0011] In the preferred embodiment, a protrusion is provided in the slot, and the slot has a chamfer at the edge; a second groove is provided on the outside of the fixture body.

[0012] The beneficial effects of this utility model are: when the steel wire is in place, the clamp on the rotating fixing device can cover the notch, so the steel wire is not easy to come out of the groove. Compared with the original setting, the steel wire is not easy to come out of the groove, and the position of the steel wire is more stable, which can improve the overall quality of thin-walled concrete.

[0019] Please see Figure 1-4 As shown, this application provides a technical solution: a thin-walled concrete revetment construction positioning clamp, including a clamp body 11, a groove 111 extending radially from the outer wall to the center on the clamp, a through hole 112 communicating with the groove 111 at the center of the clamp, and a fixing device 2 for fixing steel wire at the through hole 112.

[0020] The steel wire is inserted into the through hole 112 from the direction of the slot 111.

[0021] In a preferred embodiment, a circular first groove 113 is provided along the length of the through hole 112, and the fixing device 2 is disposed within the first groove 113.

[0022] In a preferred embodiment, the fixing device 2 includes a guide rail 21 disposed on the first groove 113 and a movable locking rod 22 disposed on the guide rail 21. The locking rod 22 can be moved to lock the connection between the through hole 112 and the slot 111, preventing the steel wire from falling out.

[0023] In a preferred embodiment, the guide rail 21 is annular and coaxial with the through hole 112. A notch 211 larger than the slot 111 is provided on one side of the guide rail 21, and the position of the notch 211 coincides with the position of the slot 111.

[0024] In the preferred embodiment, the locking lever 22 is also circular, and the overlapping part of the locking lever 22 and the guide rail 21 has a larger size than the notch 211.

[0025] When the locking lever 22 is screwed in, a portion of it still overlaps with the guide rail 21, making it less likely for the locking lever 22 to fall off from the notch 211.

[0026] Under normal circumstances, the clamping rod 22 is screwed onto the guide rail 21, exposing the notch 211, which makes it easy for the steel wire to be inserted into the through hole 112 from the groove 111. When the steel wire is in place, the clamping rod 22 is rotated to cover the notch 211, so that the steel wire is not easy to come out of the through hole 112. Compared with the original setting, the position of the steel wire is more stable, which can improve the quality of the entire thin-walled concrete.

[0027] In the preferred embodiment, the lever 22 is made of plastic.

[0028] This allows the locking rod 22 to have a certain degree of elastic deformation, enabling it to be directly inserted into the guide rail 21 from the outside. The guide rail 21 can also be made of plastic and can be glued to the first groove 113, so that the guide rail 21 and the locking rod 22 can be externally mounted and glued together in the first groove 113.

[0029] In a preferred embodiment, a protrusion 114 is provided in the slot 111, and the slot 111 has a chamfer at the edge; a second groove 116 is provided on the outside of the fixture body 11.

[0030] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
