Description

Technical Field

[0001] This utility model belongs to the technical field of concrete pouring equipment, specifically relating to a concrete pouring chute. Background Technology

[0002] Concrete pouring commonly employs methods such as pumping concrete into the formwork (pump truck, ground pump), hoisting concrete into the formwork, direct dumping concrete into the formwork by dump truck, and excavating and dumping concrete into the formwork by excavator.

[0003] Pumped concrete placement is widely used in concrete construction for buildings, bridges, water conservancy, and municipal engineering projects. In water conservancy projects, pump trucks are commonly used for pouring concrete. The suspended concrete placement method is often used in situations where the volume of concrete to be poured is small, the pouring location is high, and there is available lifting equipment. For example, it is used in the pouring of concrete in small water towers or certain sections of multi-story industrial buildings. The dump truck direct placement method can be used in some foundation projects where the appearance quality of the concrete is not critical, the pouring site is open, and there is a certain slope. For example, it can be used for the pouring of ground concrete in some large open-air parking lots and the construction of road base concrete. In sites with narrow spaces, difficulty in setting up pump trucks, and inconvenient transportation, and when the volume of concrete to be poured is small, the excavator digging and pouring method can be used.

[0004] However, the above methods are not suitable for situations where the pouring location is low, there is a certain drop, and the amount of concrete is large. For example, pouring the foundation of large hydraulic structures such as dams, or constructing large concrete foundations. Utility Model Content

[0005] The purpose of this utility model is to provide a concrete pouring chute, which has a simple structure, strong practicality, is easy and convenient to use, and is suitable for various environments on construction sites.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A concrete pouring chute includes a strip-shaped chute body, longitudinal ribs, and several transverse fixing frames. The transverse fixing frames include upper transverse ribs, lower transverse ribs, and vertical ribs. The upper transverse ribs and lower transverse ribs are connected by two symmetrical vertical ribs.

[0008] The longitudinal keel includes a lower longitudinal keel, which is symmetrically placed on the lower transverse keel and connected in series with several transverse fixing frames;

[0009] The cross-section of the strip chute is arc-shaped. The strip chute is inserted through several transverse fixed frames and placed on the longitudinal keel. The strip chute is fixed together with the transverse fixed frames and the longitudinal keel.

[0010] Preferably, the strip chute is made of a half-width double-arm corrugated pipe.

[0011] Preferably, the longitudinal keel further includes an upper longitudinal keel, which is symmetrically arranged on the sides of the trough of the strip chute and fixed to the transverse fixing frame.

[0012] Preferably, a support is provided on the longitudinal keel.

[0013] Preferably, supports are symmetrically arranged on the longitudinal keels on both sides of the chute.

[0014] Preferably, the longitudinal keel and the bracket are rotatably connected. The bracket may be a telescopic bracket.

[0015] Preferably, the outlet section of the chute is provided with a flexible hose.

[0016] Preferably, the inlet section of the chute is provided with hooks and a casting funnel.

[0017] This invention addresses the problems of high turnover rate and limited space in chutes, requiring lightweight chutes that can be easily moved and positioned by personnel. It also addresses the issues of high roughness in chute construction materials, which easily trap concrete, are difficult to clean, and prone to clogging. By using double-arm corrugated pipes as the main material for the chute, and to address the problem of long concrete transportation distances, a multi-section chute assembly method can be adopted. Through various structural improvements, a combined concrete pouring chute device has been developed and applied in constructed projects, achieving good results.

[0018] The beneficial effects of this utility model are: it provides a concrete pouring combined chute device with simple structure, reasonable design, convenient construction and good construction effect, which can quickly and easily complete the installation operation and has low construction cost.

[0020] Reference numerals: 1. Strip chute body; 2. Upper transverse keel; 3. Lower transverse keel; 4. Vertical keel; 5. Lower longitudinal keel; 6. Upper longitudinal keel. Detailed Implementation

[0021] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] like Figure 1 As shown, a concrete pouring chute includes a strip-shaped chute body 1, longitudinal ribs and several transverse fixing frames. The transverse fixing frames include upper transverse ribs 2, lower transverse ribs 3 and vertical ribs 4. The upper transverse ribs 2 and lower transverse ribs 3 are connected by two symmetrical vertical ribs 4.

[0024] The longitudinal keel includes a lower longitudinal keel 5, which is symmetrically placed on the lower transverse keel 3 and connected in series with several transverse fixing frames; the longitudinal keel also includes an upper longitudinal keel 6, which is symmetrically arranged on the sides of the trough of the strip chute body 1 and fixed to the transverse fixing frames.

[0025] The cross-section of the strip chute 1 is arc-shaped. The strip chute is inserted through several transverse fixed frames and placed on the longitudinal keel. The strip chute is fixed together with the transverse fixed frames and the longitudinal keel.

[0026] The strip-shaped chute body 1 is made of half-width double-arm corrugated pipe. Supports are installed on the longitudinal keel. Supports are symmetrically installed on the longitudinal keels on both sides of the chute.

[0027] The longitudinal keel and the bracket are rotatably connected. The bracket can be a telescopic bracket.

[0028] The outlet section of the chute is equipped with a flexible hose.

[0029] The inlet section of the chute is equipped with hooks and a pouring funnel.

[0030] This invention is applicable to various concrete pouring applications using chutes, especially in areas with narrow spaces, long horizontal concrete transport distances, and gentle longitudinal slopes. First, the double-walled corrugated pipe is divided into two halves, with one half used as the strip chute body. The chute surface made with double-walled corrugated pipes has advantages such as light weight, low roughness, difficulty in concrete adhesion, and easy cleaning. Then, the strip chute body is fixed by four longitudinal joists and horizontal fixing frames installed at certain intervals, making the chute appear square overall, facilitating transportation and on-site fixing.

[0031] Each section of this utility model of chute is 6m long. During construction, multiple sections of chute can be assembled according to site requirements. The chute should be placed on the ground as much as possible. If it needs to be suspended in the air, a telescopic support should be used for support.

[0032] The specific manufacturing process of this utility model is as follows:

[0033] 1. Half-width double-arm corrugated pipe: A 6m long double-arm corrugated pipe is cut into two half-width double-arm corrugated pipes to form a strip chute. The double-arm corrugated pipes are generally selected with a diameter of 600-800mm.

[0034] 2. Longitudinal keel: Two longitudinal keels are symmetrically installed in both directions along the outer surface of the half-width double-arm corrugated pipe to provide chute rigidity. The upper longitudinal keel is installed on the pipe edge of the half-width double-arm corrugated pipe, and the lower longitudinal keel is installed below the double-arm corrugated pipe and fixedly connected to the transverse fixing frame.

[0035] 3. Fix the horizontal fixing frame. Along the longitudinal direction of the chute, install one horizontal keel at the top and bottom of the chute every 1.5-2.0m. Connect the horizontal keel to the longitudinal keel (nail or tie). Then add one vertical keel between the two horizontal keels for fixing.

[0036] 4. One end of the chute is close to the horizontal keel, and the pipe of the chute extends out to the other end. When the two chutes are connected, the protruding part of the pipe is placed on the upper end of the horizontal reinforcement side.

[0037] 5. Supports are erected below the chute and fixed to the joints of the horizontal and vertical joists to prevent instability caused by joist movement. In practice, two movable supports can be installed on the chute. These supports can be extended, retracted, and folded away. When erecting the chute, the supports can be unfolded first and then supported on the ground via telescopic rods to form a stable triangular structure, thereby achieving the purpose of chute erection.

[0038] 6. A flexible hose can be installed at the outlet section of the chute as needed. The hose can be made of rubber and its diameter is the same as or larger than that of the chute. This allows the concrete in the chute to flow directly into the hose, effectively preventing concrete splashing and reducing concrete loss. It also makes it easier for operators to pour concrete in the surrounding area.

[0039] 7. As needed, hooks can be added to the inlet section of the chute to connect with the tank truck outlet. A funnel can also be installed, filled with concrete, which flows into the chute from the funnel, making it easy to move.

[0040] The keel and support frame of this invention can be made of wood or steel pipe. The various components are fixedly connected by wire binding or nailing.

[0041] For any content not described in detail in this utility model, conventional technical knowledge in the field can be used.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
