Description

[Technical field]

[0001] The invention relates to the technical field of side wall hoisting, and in particular to a device and a method for correcting eccentric hoisting of a prefabricated culvert side wall component. [Background technology]

[0002] With the rapid development of my country's economy, infrastructure construction is in full swing. With the acceleration of infrastructure construction, the project construction is required to be completed quickly during the construction process. Prefabricated prefabricated components can quickly complete the installation and construction of the project while ensuring quality, meeting the current infrastructure construction requirements. More and more infrastructure construction uses concrete prefabricated components to achieve rapid construction. In the rapid application of prefabricated components, the hoisting of components is the key process to complete prefabricated construction. With the application of prefabricated construction in various projects, the requirements for the hoisting of concrete prefabricated components in projects are getting higher and higher.

[0003] In infrastructure, when constructing new or expanding highways or railways and other facilities, culvert construction is a key project that determines whether the project can enter full construction. Prefabricated culvert construction provides a guarantee for the rapid completion of culvert construction. At present, the prefabricated culvert side wall structure adopts a single-side reserved lifting ring for lifting, which not only simplifies the production of prefabricated molds, but also facilitates the pouring of prefabricated concrete components. At the same time, it also meets the requirements of culvert clearance and prevents the appearance of lifting rings in the culvert clearance, which may cause safety hazards in the operation process.

[0004] During the construction of prefabricated culverts, the lifting construction of side wall components is mainly based on eccentric lifting. However, there are currently main problems with the eccentric lifting of side wall components during the prefabricated construction of culverts: 1. Concrete components collide with the ground, etc., damaging the structural lines and structures. 2. Single-sided lifting is prone to inaccurate positioning, requiring repeated lifting and adjustment of positions, etc., which reduces the efficiency of culvert lifting. 3. Single-sided lifting causes single-sided force on concrete, requiring the laying of reinforcing steel bars, which increases costs. 4. Single-sided lifting of components causes large cable stress, which reduces the safety of lifting prefabricated culvert side wall components under the same conditions. How to solve the problem of eccentric lifting of components during the lifting process has become a key point in the current rapid construction of transportation facilities. Therefore, it is urgent to apply a method and model for correcting the eccentric lifting problem of prefabricated side wall components to ensure the vertical lifting and installation of prefabricated side wall components, reduce the damage to components caused by eccentric lifting and increase in economic costs, which is also a technical problem that infrastructure urgently needs to solve.

[0005] At present, there is still a lack of eccentric lifting solutions in the construction process of prefabricated culverts. [Summary of the invention]

[0034] The second panel 2 is provided with a first side panel 7 and a second side panel 8 which are arranged vertically and parallel to each other, so that a gap is formed between the first side panel 7 and the second side panel 8 for fixing and inserting the prefabricated culvert side wall component 200; a vertical plate 9 is also provided on the side of the first side panel 7 away from the gap, and a second through hole 10 is also provided on the end of the vertical plate 9 away from the second panel 2, and a notch 11 for the lifting ring to be exposed is also provided on the end of the first side panel 7 away from the second panel 2, and a second rod 12 is simultaneously penetrated through the second through hole 10 and the lifting ring, so that the prefabricated culvert side wall component 200 is fixedly connected to the vertical plate 8, and further the prefabricated culvert side wall component 200 is fixedly connected to the device 100. The vertical plate 9 not only plays the role of fixed connection with the lifting ring of the prefabricated culvert side wall component 200, but also plays the role of reinforcing the device 100 of the present invention. Among them, the first panel 1, the second panel 2 and the support plate 3 are all 10mm thick steel plates, and the vertical plate 9 is 16a channel steel. The first rod 5 and the second rod 12 are both round rods.

[0038] Furthermore, an I-beam 19 is fixedly disposed between the first panel 1 and the second panel 2, and the vertical portion of the I-beam 19 is located between the two rows of the first through holes 4.

[0040] A method for hoisting using the above-mentioned device for correcting eccentric hoisting of prefabricated culvert side wall components comprises the following steps:

[0041] (1) The first rod 5 is passed through the first through hole 4, and the first rod 5 is fixed to the support plate 3 by bolts, and one end of the suspension rope 6 is passed through the third through hole 15 and then fixed to the first rod 5;

[0042] (2) After the device 100 is vertically lifted by a crane through a lifting rope 6, the device 100 is placed on the prefabricated culvert side wall member 200 by utilizing the gap between the first side plate 7 and the second side plate 8;

[0043] (3) Using the second rod 12 to simultaneously pass through the second through hole 10 on the vertical plate 9 and the lifting ring on the prefabricated culvert side wall component 200, the device 100 is connected to the prefabricated culvert side wall component 200 to form a combined whole;

[0044] (4) The combined whole formed by connecting the device 100 and the prefabricated culvert side wall component 200 is then hoisted. During the hoisting, the hoisting angle α is greater than 60°. Since the second side plate 8 of the device 100 is in close contact with the prefabricated culvert side wall component 200, it can be ensured that the prefabricated culvert side wall component 200 does not swing arbitrarily during the hoisting process, so that the hoisting point, the center of gravity of the prefabricated culvert side wall component and the center of gravity of the combined whole are on the same vertical line (such as Figure 4 ).

[0045] In the present invention, the device 100 of the present invention is fixedly connected with the prefabricated culvert side wall component 200 to form a whole, and the prefabricated culvert side wall component 200 is vertically hoisted so that the lifting point, the center of gravity of the prefabricated side wall and the center of gravity of the combined whole are on the same vertical line (such as Figure 4 ), which solves the problem of inaccurate positioning during eccentric hoisting. The present invention sets a circular first rod 5 so that one end of the hoisting rope 6 is fixed on the circular first rod 5, instead of directly tying the hoisting rope 6 to the support plate 3 or the first panel 1, thereby reducing the shear force on the wire rope at the connection and improving the service life of the wire rope. When hoisting, the hoisting angle α is greater than 60 degrees, which reduces the horizontal shear force of the hoisting rope 6, further improves the service life of the hoisting rope 6, and increases the safety of the hoisting process of the prefabricated culvert side wall component 200. By setting a first rectangular plate 13, a first triangular plate 14, a second triangular plate 16, a second rectangular plate 17, a third triangular plate 18, etc. for reinforcing, the device 100 is formed as a whole, and the I-beam 19 is used as the main force distribution component, so that the overall force of the device 100 is uniform, and the large deformation of the steel plates such as the first panel 1, the second panel 2, the first side plate 7, the second side plate 8 and the vertical plate 9 due to excessive load is reduced, and the prefabricated culvert side wall component 200 is prevented from shaking during the hoisting process. Therefore, the present invention corrects the problem of eccentric hoisting of the prefabricated culvert side wall component 200, is simple to operate, has fewer hoisting steps, and improves the construction efficiency of the prefabricated culvert.

[0046] The above description is a detailed description of the preferred feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modified changes completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
