Problems solved by technology

Since the progress of the linear water conservancy project is greatly affected by the prefabrication speed of the aqueduct prefabricated components, the conventional method of on-site binding of steel bars on the storage space directly arranges the channel body steel bar binding process on the key construction route of the project, and the multi-rib structure The formwork is complicated and difficult to install. If it is constructed alternately with the steel bar installation process, construction interference will inevitably occur between them, which will have a great impact on the construction progress of the tank body

Embodiment 1

[0037] like Figures 1~5 Among them, a multi-rib three-way prestressed prefabricated trough body reinforcement installation platform, the main beam trough body 1 is located on both sides, and a plurality of secondary beam platforms perpendicular to the main beam trough body 1 are arranged between the main beam trough bodies 1 The frame hole 6, the sub-beam installation area frame 2 is formed between each sub-beam frame hole 6;

[0038] The depth of the two ends of the main beam groove body 1 is greater than the depth in the middle, and there are also end reinforcement grooves 9 near the two ends of the main beam groove body 1. The end reinforcement grooves 9 are parallel to the secondary beam platform holes 6. The depth is greater than the depth of the secondary beam stand hole 6 . In a preferred solution, the main beam groove body 1 , the secondary beam platform hole 6 and the end reinforcement groove 9 are all located below the ground 11 . With this structure, it is conven...

Embodiment 2

[0047] On the basis of Example 1, as Figures 1~6In the above, an installation method of the above-mentioned multi-rib three-way prestressed prefabricated groove body reinforcement installation bench, comprising the following steps:

[0048] 1. According to the structural dimensions of the long-span multi-rib prefabricated trough body, the detailed dimensions of the special bench for the installation of the multi-rib steel bar for the large-span trough body are designed. 9. Before excavation, use measuring instruments to accurately set out;

[0049] Preferably, the main girder groove body 1 is excavated mechanically, and the bench 2 in the secondary girder installation area is excavated manually.

[0050] 2. The base layer of the steel bar installation platform is hardened and leveled, the horizontal surface is made of concrete, the facade is made of brick structure, and the surface of the brick structure is set with mortar plastering;

[0051] 3. Install two lateral elevati...

Abstract

The invention provides a multi-rib three-direction prestressed prefabricated trough body reinforcement installation platform, the main beam trough body is located on both sides, and a plurality of secondary beam platform holes perpendicular to the main beam trough body are arranged between the main beam trough bodies , the secondary beam installation area bench is formed between the holes of each secondary beam bench; the depth of the two ends of the main beam groove body is greater than the depth of the middle, and there are also end reinforcement grooves near the two ends of the main beam groove body, and the depth of the end reinforcement grooves is Greater than the depth of the secondary beam gantry hole. The installation sequence of primary and secondary beams is secondary beam, main beam, side wall, bottom plate, and overall transfer. The installation method of the present invention cooperates with the special steel bar installation platform, greatly improves the construction efficiency of the multi-rib three-way prestressed prefabricated groove body, and speeds up the project progress. By adopting the device and method of the present invention, the installation of a large number of special-shaped structural steel bars for the main beam and the secondary beam of a single trough can be completed quickly and efficiently within 96 hours, and the operation conditions of the next process are satisfied, and the construction time of the trough body is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of multi-rib prestressed aqueduct construction, in particular to a multi-rib three-direction prestressed prestressed aqueduct steel reinforcement installation platform and an installation method. Background technique [0002] In recent years, with the rapid development of lifting technology, super-large tonnage engineering lifting equipment has been widely used in the construction of large-scale water conservancy aqueduct projects, so aqueduct construction technology has also derived a new development direction, factory standardized prefabrication Aqueduct technology has been developed to a certain extent. Since the progress of the linear water conservancy project is greatly affected by the prefabrication speed of the prefabricated components of the aqueduct, the conventional method of tying steel bars on site in the warehouse directly arranges the steel bar binding process of the aqueduct on the key constru...
