[0002] In high-rise and super-high-rise construction projects, when the construction reaches a certain height, it is difficult for the boom-type concrete pump truck to pump concrete to the construction pouring floor. This requires the installation of vertical concrete pumping pipes on the poured floors, and the delivery of concrete to the construction floors by high-pressure pumping. Concrete will generate huge impact force during the pumping process, causing strong vibrations, and even damage the floor slabs and concrete delivery pump pipes, which affects the construction quality and also poses a great safety hazard. The more commonly used method is to use wooden blocks to fill and fix the gaps in the reserved holes after the pumping pipe is installed, but this method is prone to waste of materials, and the impact and vibration will also cause the wooden blocks to fall off, which is dangerous. In addition, the fixing and disassembly process is complicated, and it is difficult to flexibly adjust the fixing effect according to actual conditions. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.

[0021] Example: Figure 1-Figure 4 As shown, a concrete pumping pipe fixing device comprises an upper clamping plate 1 and a lower clamping plate 2, which are connected by bolts and are used to be clamped on the floor slab; a limiting rod 3 is rotatably connected to the upper clamping plate 1, and a limiting plate 4 is slidably connected to the lower clamping plate 2, and the inner side surface of the limiting plate 4 is provided with a plurality of strip-shaped grooves 5 that can be mutually engaged with the limiting rod 3, and the outer side surface of the limiting plate 4 is provided with an arc-shaped groove 7 that can be mutually engaged with the concrete pumping pipe 6.

[0022] Furthermore, the upper splint 1 is configured as a right-angle Z-shaped structure, and two wing columns 8 are provided at the upper end of the upper side plate of the upper splint 1, and a rotatable rotating shaft 9 is provided between the two wing columns 8. A through hole 10 is provided at the top of the wing column 8 to provide non-fixed support for the two ends of the rotating shaft 9. The limit rod 3 is fixed on the rotating shaft 9, and the bottom of the limit rod 3 is connected to the top of the upper side plate of the upper splint 1 through a spring 11.

[0023] Furthermore, right-angled triangle plates 12 are provided on the upper sides of both ends of the lower clamping plate 2, and oval sliding holes 13 are provided on the two right-angled triangle plates 12. Oval sliding blocks 14 are provided on both ends of the limiting plate 4, and the two sliding holes 13 are respectively provided for the sliding blocks 14 at both ends of the limiting plate to slide. The right-angled triangle plates 12 are vertically fixed on the lower clamping plate 2 parallel to and close to the floor slab. The width of the lower clamping plate 2 is longer than the bottom side of the right-angled triangle plates 12. The extended part and the right-angled long side of the right-angled triangle plates 12 form an L-shaped structure closely attached to the lower positive angle of the floor slab, and the sliding holes 13 are provided parallel to the hypotenuse of the right-angled triangle plates 12. The waist positions of the opposite sides of the two right-angled triangle plates 12 are connected by a transverse connecting rod 15, and two symmetrical threaded rods 16 are arranged on the upper end of the transverse connecting rod 15. A limiting hole 17 matching the threaded rod 16 is arranged on the lower side plate of the upper clamping plate 1. The threaded rod 16 is connected to the limiting hole 17 by a nut 18, and a washer is arranged at the lower end of the nut 18. The threaded rod 16 adopts a double-threaded rod. The double-thread thread has better transmission performance and higher firmness than the single-thread thread, which can effectively avoid the problem of failure of the fixing device due to broken threads or loose bolts caused by construction impact vibration, and can effectively ensure the safety and fixing strength of the device.

[0024] Furthermore, the slot 7 is connected to the limit plate 4 through a connecting rod 19, and a rubber gasket is provided on the inner side of the slot 7 to increase the friction between it and the concrete pumping pipe 6, enhance the limiting and fixing effect, and also play an effective buffering role between the slot 7 and the concrete pumping pipe 6, thereby reducing the damage to the device caused by the impact of the concrete pumping pipe 6 during construction.

[0025] In this embodiment, the limit plate 4 is embedded in the sliding hole 13 through the slider 14 to realize the assembly connection of the two groups of components. At the same time, the sliding hole 13 is used as a moving track to realize the oblique upward and downward movement of the limit plate 4, and then the fastening strength is adjusted according to the position of the concrete pumping pipe 6 in the floor hole. The specific method is: press down the connecting rod 19 to realize the overall downward movement of the limit plate 4, and the lower the position, the greater the fastening strength. However, in the actual construction process, the concrete pumping pipe 6 has a large impact vibration, which will cause the limit plate 4 to loosen and move upward. In order to solve this problem, a groove 5 is designed in the device to flexibly limit and fix the limit plate 4, specifically: adjust the limit plate 4 to an appropriate position, and then rotate the limit rod 3 so that its end is engaged with a certain groove 5. At the same time, the spring 11 can provide elastic support for the limit rod 3 to ensure that the limit rod 3 does not slip from the groove 5 due to its own weight and lose the limiting effect.

[0026] After use, by pressing down the limit rod 3, moving the limit plate 4 diagonally upward, and unscrewing the connecting bolts, the entire device can be dismantled and recycled. This device changes the shortcomings of the traditional fixing method, such as waste of resources, unstable effect, and potential safety hazards. The pumping pipe fixing device can be flexibly installed according to the thickness of the floor slab, which is safe and reliable; the fastening effect can be flexibly adjusted according to the position of the pumping pipe; the entire concrete pumping pipe fixing device is easy to disassemble and easy to recycle.

[0027] The construction method of the concrete pumping pipe fixing device comprises the following steps: S1. According to actual construction requirements, the concrete pumping pipe 6 is vertically installed from bottom to top through the reserved holes of the floor slabs of each floor to the construction operation floor; S2, installing the concrete pumping pipe fixing device on the floor slab; S3, according to the position of the concrete pumping pipe 6 in the floor hole, the limit plate 4 is adjusted to a proper position to provide a suitable supporting and fastening effect, and then the limit rod 3 is used to limit and fix the limit plate 4 through the groove 5, and the concrete pumping pipe 6 is fixed through the clamping groove 7; S4, after the construction is completed, press down the limit rod 3, move the limit plate 4 obliquely upward, unscrew the nut 18, and the whole device can be disassembled in reverse for turnover.

[0028] The above are only implementation modes of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent schemes made using the contents of the present invention specification, directly or indirectly applied in other related technical fields, are also within the patent protection scope of the present invention.
