Technical Field

[0001] The utility model belongs to the technical field of the installation of assembled PC precast components, and particularly relates to a fixing tool for a cantilever square pipe of an assembled PC precast component. Background Art

[0002] An assembled PC precast component refers to a concrete product processed and produced in a factory in a standardized and mechanized manner, which is widely used in fields such as construction, transportation, and water conservancy, and plays an important role in the national economy.

[0003] When an assembled PC precast component is installed, it is necessary to temporarily fix the support member. Both ends of the cantilever square pipe serving as a support need to be temporarily fixed on the channel steel beam. Currently, holes are drilled in the cantilever square pipe and the channel steel, and the square pipe is fixed to the channel steel beam with bolts.

[0004] However, due to the low reuse rate, drilling takes a lot of time, and corresponding holes need to be drilled in the cantilever square pipe and the channel steel, which affects the service life of the square pipe and the channel steel. In addition, the installation and disassembly of bolts through hole alignment both take a lot of time, affecting the installation efficiency of the assembled PC precast component. Summary of the Utility Model

The top of the U-shaped clamping plate is connected to the cover plate. Both side walls of the U-shaped clamping plate are in a C-shaped structure. A through hole is formed in the middle of the cover plate, and a nut is coaxially connected to the through hole. The fixing bolt is threadedly connected to the nut.

[0007] Further, both sides of the cover plate have inwardly bent hook-shaped structures, and slots matching the hook-shaped structures are formed at the tops of both side walls of the U-shaped clamping plate, and the hook-shaped structures are inserted into the slots.

[0008] Furthermore, one side of the cover plate is rotatably connected to the top of one side wall of the U-shaped clamping plate through a hinge, and the other side of the cover plate is connected to the top of the other side wall of the U-shaped clamping plate through a buckle.

[0009] Furthermore, the opening width of the C-shaped structure is one-half of the side wall width of the U-shaped clamping plate.

[0010] Furthermore, the distance between the lower edge of the opening of the C-shaped structure and the lower edge of the side wall of the U-shaped clamping plate is greater than the width between the upper edge of the opening of the C-shaped structure and the upper edge of the side wall of the U-shaped clamping plate.

[0011] Further, the width of the cover plate is less than the length of the slot.

[0012] Further, the fixing bolt is an external hexagonal bolt.

[0013] The prefabricated PC precast component cantilever square pipe fixing tooling provided by the utility model utilizes the C-shaped structure on the side wall of the U-shaped clamping plate to be clamped with the bending part of the channel steel, and limits the square pipe by rotating the fixing bolt to press the square pipe and the channel steel.

[0020] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further details the utility model with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0021] See Figure 1 , 3 , 4, 5, the embodiment of the utility model provides a prefabricated PC precast component cantilever square pipe fixing tooling for temporarily fixing the square pipe 02 on the channel steel 01. This tooling includes a U-shaped clamping plate 1, a cover plate 2 and a fixing bolt 3. The top of the U-shaped clamping plate 1 is connected to the cover plate 2. Both side walls of the U-shaped clamping plate 1 are C-shaped structures. A through hole is opened in the middle of the cover plate 3, and a nut 4 is coaxially connected to the through hole. The fixing bolt 3 is threadedly connected to the nut 4.

[0022] The U-shaped clamping plate 1 is composed of a bottom plate and two side walls perpendicular to the bottom plate. The distance between the two side walls is slightly larger than the width of the square tube 02. When in use, the square tube 02 passes through between the two side walls of the U-shaped clamping plate 1.

[0023] The cover plate 2 is fixedly connected or detachably connected to the top of the U-shaped clamping plate 1. When the cover plate 2 is fixedly connected to the U-shaped clamping plate 1, this tooling can be sleeved on the square tube 02 from one end of the square tube 02.

[0024] When the cover plate 2 is detachably connected to the U-shaped clamping plate 1, the cover plate 2 and the U-shaped clamping plate 1 can be combined into a whole, and the cover plate 2 can also be disassembled from the top of the U-shaped clamping plate 1, which is suitable for the situation where there is not enough space at both ends of the square tube 02 for this tooling to be sleeved from both ends of the square tube 02. When the cover plate 2 is disassembled, the U-shaped clamping plate 1 can be buckled on the bottom of the square tube 02 from below the square tube 02, and then the cover plate 2 and the U-shaped clamping plate 1 can be connected.

[0025] When the cover plate 2 is detachably connected, as Figure 2 shown, in an embodiment of the present utility model, both sides of the cover plate 2 have hook-shaped structures 5 bent inward, and slots 6 matching the hook-shaped structures 5 are provided at the tops of the two side walls of the U-shaped clamping plate 1, and the hook-shaped structures 5 are inserted into the slots 6.

[0026] The cover plate 2 and the U-shaped clamping plate 1 are combined into a whole by inserting the hook-shaped structures 5 on both sides of the cover plate 2 into the slots 6. In addition, in order to facilitate the cover plate 2 to drive the fixing bolt 3 to press different positions of the square tube 02 within a small range to find a stable fixing point, the width of the cover plate 2 is set to be smaller than the length of the slot 6. In this way, the position of the cover plate 2 can be changed by sliding the position of the hook-shaped structure 5 in the slot 6, and then the position of the fixing bolt 3 can be changed.

[0027] When the cover plate 2 is detachably connected, in another embodiment of the present utility model, one side of the cover plate 2 is rotatably connected to the top of one side wall of the U-shaped clamping plate 1 through a hinge, and the other side of the cover plate 2 is connected to the top of the other side wall of the U-shaped clamping plate 1 through a buckle. The buckle can not only press the cover plate 2 tightly on the top of the U-shaped clamping plate 1 to keep the structure of the tooling stable, but also facilitate opening and closing.

[0028] In order to ensure the structural strength of the U-shaped clamping plate 1, in the embodiment of the present utility model, the opening width of the U-shaped structure on the side wall of the U-shaped clamping plate 1 is one-half of the side wall width of the U-shaped clamping plate 1. In addition, the distance between the lower edge of the opening of the U-shaped structure and the lower edge of the side wall of the U-shaped clamping plate 1 is greater than the width between the upper edge of the opening of the U-shaped structure and the upper edge of the side wall of the U-shaped clamping plate 1.

[0029] The fixing bolt 3 can be an external hexagonal bolt or an internal hexagonal bolt, which can bear a greater load and has a long service life.

[0030] When the cantilever square pipe fixing tooling for the assembled PC precast component provided by the embodiment of the present utility model is in use, if the cover plate 2 is fixedly connected to the U-shaped clamping plate 1, first place the two ends of the square pipe 02 on the channel steel 01. After adjusting the position of the square pipe 02, sleeved the U-shaped clamping plate 1 of the tooling from the end of the square pipe 02 onto the square pipe 02, so that the lower edge and the side edge of the U-shaped opening on the side wall of the U-shaped clamping plate 1 are respectively attached to the inner groove surface of the channel steel 01 and the top surface of the groove side wall. Rotate the fixing bolt 3 with a wrench so that the flat surface at the bottom of the fixing bolt 3 presses the square pipe 02 against the surface of the channel steel 01, thereby limiting and fixing the square pipe 02.

[0031] If there is not enough space at both ends of the square pipe 02 to sleeve the tooling, then use the tooling with the cover plate 2 detachably connected to the U-shaped clamping plate 1. When installing this tooling, the cover plate 2 can be opened first, and the U-shaped clamping plate 1 is buckled onto the bottom of the square pipe 02 from below the square pipe 02, and then the cover plate 2 is connected. The connection method can be the insertion of the hook-shaped structure 5 and the slot 6 in the above embodiment, or it can be a snap connection.

[0032] After the tooling is used up, loosen the fixing bolt 3 to release the fixation, and then the tooling can be removed.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
