Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to an expandable and contractible flexible conduit for concrete pouring. Background Technique
[0002] A thin-walled structure is a structure composed of thin plates, thin shells and slender members, which can withstand large loads with less weight and less material. Wooden houses are the products of the early use of thin-walled structures by humans. Each member of the thin-walled structure may be subjected to axial force, shear force and bending moment, and each plate and shell may be subjected to bending moment, shear force and tensile or compressive force in the middle plane.
[0003] For the concrete pouring of high thin-walled structures, due to the small cross-sectional size and dense steel bars, the concrete conduit cannot penetrate deep into the structure, resulting in a high concrete drop, easy segregation of concrete, and thus unqualified concrete forming quality and potential leakage hazards. Therefore, we designed an expandable and contractible flexible conduit for concrete pouring. Content of the Utility Model
[0004] The purpose of the utility model is to provide an expandable and contractible flexible conduit for concrete pouring to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: An expandable and contractible flexible conduit for concrete pouring, including a flexible conduit for conveying concrete, and fixed buckles and clamps are respectively arranged at both ends of the flexible conduit. A steel bar frame is lapped on the side surface of the flexible conduit, and a formwork is lapped on the lower surface of the steel bar frame. The shape of the formwork is concave. A support plate is lapped on the upper surface of the formwork. A concave rod is arranged on the side surface of the support plate. A roller I is sleeved on the surface of the concave rod. A bearing is arranged on the front surface of the support plate. The inner ring of the bearing is fixedly connected with a support rod. The top end of the support rod is fixedly connected with a cross bar, and a roller II is sleeved on the surface of the cross bar. A connecting plate is fixedly connected to the front surface of the support plate, and a counterbore is opened on the upper surface of the connecting plate.
[0006] On the basis of the above technical solution, the utility model can also be improved as follows.
[0007] Preferably, the material of the flexible conduit is rubber with good wear resistance and toughness. The inner ring surface of the clamp is fixedly connected with the surface of the material conveying end of the flexible conduit. The feeding end of the flexible conduit is connected with the discharging end of the truck-mounted concrete pump through a fixed buckle. By arranging a clamp at the bottom end of the flexible conduit, it is convenient to increase the insertion and downward movement effect of the flexible conduit.
[0008] Preferably, both sides of the steel bar frame are respectively lapped with the inner side walls of the concave template, and the discharging end of the flexible conduit is located inside the concave template, and the height difference between the end of the flexible conduit and the concrete pouring point is not more than two meters, preventing the pouring from being too high and the concrete from segregation, which affects the quality of concrete pouring.
[0009] Preferably, the surface of the first roller is lapped with the inner corner surface of the flexible conduit, and the first roller is located above the steel bar frame. By arranging the first roller at the corner of the flexible conduit, it is convenient for the flexible conduit to move downwards, preventing the flexible conduit from rubbing against the template or steel bars, and increasing the service life of the flexible conduit.
[0010] Preferably, bearings are embedded in the front and back surfaces of the support plate, and the outer rings of the two bearings are respectively fixedly connected to the front and back surfaces of the support plate, and the inner rings of the two bearings are fixedly connected with support rods. By arranging the bearings and support rods, it is convenient for the support rods to flip through the bearings, increasing the use and storage effects of the support rods.
[0011] Preferably, support rods are fixedly connected to both ends of the cross bar, and the cross bar is parallel to the surface of the support rods. The lower surface of the second roller on the surface of the cross bar is movably connected to the surface of the flexible conduit. By arranging the cross bar and the second roller, it is convenient for the support rods, the cross bar and the second roller to limit the flexible conduit, preventing the flexible conduit from displacing during the process of conveying concrete.
[0012] Preferably, connecting plates are fixedly connected to the front and back surfaces of the support plate, and the lower surfaces of the connecting plates and the support plate are on the same horizontal plane. By arranging the connecting plates on the front and back surfaces of the support plate, it is convenient for the connecting plates to be fixed to the template and the ground through bolts.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:
[0015] Through the provided flexible conduit of the present utility model, before concrete pouring, it is convenient to fix the flexible conduit at the front end of the guide rail of the truck pump or the ground pump through the fixing buckle, and then fold the flexible conduit and insert it into a suitable position inside the thin-wall structure of the template.
