[0021] In order to facilitate the understanding of the present application, the present application will be described in more detail below in conjunction with the drawings and specific embodiments. However, the present application can be implemented in many different forms, and is not limited to the embodiments described in the specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present application more thorough and comprehensive.
[0022] Embodiment 1: in combination Figures 1-2 It is understood that a pre-embedded pipe for basement construction column concrete conveying includes: a pipe mouth section 1, which is internally hollow; a chute pipe section 2, which is internally hollow, is fixedly installed below the pipe mouth section 1 and is structured with the pipe mouth section 1 to form a channel for concrete flow, the bottom inner contour line of the pipe mouth section 1 falls on the top inner contour line of the chute pipe section 2; a pipe clamp 3 is arranged outside the chute pipe section 2.
[0023] Usage instruction: installation before use, the pre-embedded pipe is installed close to the primary structure column 4, when the basement roof concrete is poured, the pipe mouth section 1 is pre-embedded, and the size meeting the design requirements is selected according to the actual needs. For example, the pipe mouth section 1 is pre-embedded on the garage roof 5. In the secondary structure construction, the chute pipe section 2 is fixedly connected below the pipe mouth section 1 to the basement, and the pipe clamp 3 is used in combination with the screw nail to surround and fix it on the primary structure column 4, so that the chute pipe section 2 is stable; the exposed pipe mouth section 1 can be wrapped with concrete and painted with warning color to avoid being damaged, and the overall structure is stable. After the overall installation of the pre-embedded pipe is completed, the pipe mouth section 1 and the chute pipe section 2 form a concrete conveying chute from the ground to the ground. When concrete is needed in the secondary structure construction, a bend joint is used to extend to the pipe mouth section 1, and concrete can be quickly conveyed from the concrete conveying chute to the basement, which shortens the concrete conveying time and improves the concrete pouring quality; less labor is required.
[0024] After the construction is completed, the chute pipe section 2 is cut off, and the pipe mouth section 1 is backfilled.
[0025] Embodiment 2: on the basis of the structure of embodiment 1, in this embodiment, the pipe mouth section 1 is a hollow circular pipe, which can be made of PVC material; the chute pipe section 2 is a hollow conical pipe with the pipe diameter gradually decreasing from top to bottom; and the maximum pipe diameter of the chute pipe section 2 is not less than the bottom pipe diameter of the pipe mouth section 1, so that there is no material blocking step, ensuring smooth concrete conveying.
[0026] For the maximum pipe diameter of the chute pipe section 2 being equal to the bottom pipe diameter of the pipe mouth section 1, the bottom of the pipe mouth section 1 and the top of the chute pipe section 2 are respectively provided with flanges corresponding in size and bolt hole position, and are fastened and connected by fastening bolts, the pipe mouth section 1 and the chute pipe section 2 are seamlessly and smoothly connected, and refer to Figure 3 It is understood.
[0027] For the maximum pipe diameter of the chute section 2 is greater than the bottom pipe diameter of the pipe section 1, the bottom of the pipe section 1 and the top of the chute section 2 are respectively provided with flanges, and are connected by expanding and connecting through fastening bolts, and the inner contour line of the bottom of the pipe section 1 falls on the inner contour line of the top of the chute section 2, as shown in Figure 4 It is understood that the top connecting part of the chute section 2 is designed to be bent upwards to form a buckling plate 201, and the flanges on the pipe section 1 are designed to be petal-shaped butt blocks 101, and gaps are formed between adjacent butt blocks 101, as shown in Figure 5 The buckling plate 201 is also designed to be petal-shaped, and during installation, the buckling plate 201 is first embedded into the gaps between the butt blocks 101, and then is rotated to be hung on the butt blocks 101, and then is fastened by using fastening bolts, so that the installation is more convenient and the structure is stable. The present application mainly forms a concrete chute, and the expanding and connecting butt blocks are not contacted by concrete, that is, the chute section 2 is not a force-bearing part.
[0028] In one embodiment, the pipe clamp 3 is tangent to the outer wall of the chute section 2, and there are at least two tangent points. The pipe clamp 3 plays a role in fixing the chute section 2.
[0029] In one embodiment, a plurality of pipe clamps 3 are equidistantly distributed on the outer wall of the chute section 2. Multiple fixing points make the chute section 2 stable and safe to use.
[0030] In one embodiment, the pipe clamp 3 is a U-shaped frame with a right angle. The chute section 2 is formed to be outwardly expanded and protected, and the structure is more durable.
[0031] In some embodiments, the pipe section 1 and the chute section 2 can have a circular or square cross section, and can be variable-diameter or constant-diameter. The pipe section 1 can also be a galvanized pipe. The pipe clamp 3 can be a steel wire rope, which binds the chute section 2 and is fixed at the end of the structural column 4.
[0032] The present application uses a pipeline to form a concrete conveying chute, so that the concrete can be quickly conveyed to the basement, and the concrete conveying time is shortened, and the labor cost is also reduced. The pipe section 1 is pre-buried on the top plate of the basement, and the chute section 2 is fixed on the structural column by using pipe clamps and screws, so that it is stable and can be repeatedly used for quick conveying, solving the problem of large demand and small single transportation capacity of the bucket car, obviously shortening the concrete conveying time, and facilitating the construction, reducing the concrete waiting time on site, improving the concrete pouring quality, and reducing the construction difficulty.
[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
