Conveying and pouring device based on concrete construction of high-rise building

Abstract

The invention relates to the field of concrete pouring equipment, and discloses a conveying and pouring device based on the concrete construction of a high-rise building. According to the conveying and pouring device based on the concrete construction of the high-rise building, high-rise concrete conveying pipelines are arranged on a tower crane standard section and a tower crane boom, and the length of each section of vertical pump pipes is consistent with the length of the tower crane standard section and increases at the same time. The conveying and pouring device has the characteristics ofsimple operation, flexible rotation and the like. The conveying and pouring device based on the concrete construction of the high-rise building structurally comprises a vertical conveying pipeline arranged in the tower crane standard section and a transverse conveying pipeline arranged on the side surface of the tower crane boom. The upper end part of the vertical conveying pipeline is connectedto the left end part of the transverse conveying pipeline through a first elbow, and rotating joints matched with the vertical conveying pipeline and the transverse conveying pipeline are arranged atthe two end part of the first elbow correspondingly. A shock absorption fixed assembly device matched with the tower crane standard section is arranged on the vertical conveying pipeline, and a supporting assembly matched with the transverse conveying pipeline is fixedly arranged on the side surface of the boom. The conveying and pouring device based on the concrete construction of the high-rise building is simple in operation and convenient to use, and is suitable for all kinds of building construction sites, especially for the construction of the high-rise building.

Description

Technical field [0001] The invention relates to the field of concrete pouring, in particular to a conveying and pouring device based on high-rise building concrete construction. Background technique [0002] At present, the concrete construction of high-rise buildings mainly uses fixed pumps and spreaders, assisted by tower cranes to complete the conveying and pouring of concrete. However, the following problems inevitably exist in the use of the above-mentioned machinery: [0003] 1. In large-area pouring, due to the limitation of the distributor itself, the material radius is small, which cannot meet the actual cloth range, and multiple distributors are required for cross pouring. In the blind area of ​​the pouring, the material is often cut from the same part of the pillar or shear wall. Until the concrete is poured, this will often cause excessive side pressure on the single-sided formwork, resulting in explosion or expansion; at the same time, because the concrete flows in th...

AI Technical Summary

Problems solved by technology

[0003] 1. In large-area pouring, due to the limitation of the placing machine itself, the distributing radius is small, which cannot meet the actual distributing range. Multiple placing machines are required for cross pouring. In the blind spot of pouring, the material is often cut from the same part of the column or shear wall. Until the concrete is poured, this will often cause excessive side pressure of the single-sided formwork, resulting in mold explosion or expansion; at the same time, because the concrete flows in the same direction, the pressure on both sides is unbalanced, causing the shear wall or column formwork to move in the same direction. Biased

[0004] 2. Before setting up the placing machine, it is necessary to reserve enough working space and the mechanical self-weight load directly acts on the pouring surface, which may easily cause displacement, deformation, damage or blockage of the formwork, steel bars, reserved holes, embedded parts, and inserting bars.

[0005] 3. When pouring concrete at each level, a concrete delivery pump must be temporarily installed at the operation level. After the pouring is completed, a section of the pump pipe will be dismantled, which takes a lot of time and effort.

Due to the high pressure of the fixed delivery pump, when the concrete is delivered, the pump pipe vibrates back and forth on the surface of the formwork, resulting in structural cracks during the initial setting of the poured concrete, and the noise disturbs the residents

[0006] 4. During the pouring process of the placing machine, 4-6 people are required to pull the pipe. On the one hand, the labor cost is increased, the labor intensity is high, and the pouring time is too long. , so that the protective layer is oversized and unevenly distributed, resulting in structural cracks in the poured concrete floor

The formwork support is vibrated by the distribution machine, causing the formwork to sink, causing the concrete floor to be bent and uneven, and a series of common quality problems in the concrete floor.
