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] Such as Figure 1~5 Among them, a multi-ribbed three-way prestressed prefabricated channel body reinforcement installation platform, the main beam channel body 1 is located on both sides, and a plurality of secondary beam platforms perpendicular to the main beam channel body 1 are arranged between the main beam channel body 1 Frame holes 6, the frame 2 of the secondary beam installation area is formed between the secondary beam frame holes 6;

[0038] The depth of the two ends of the main beam tank body 1 is greater than the depth in the middle, and there are 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 stand holes 6, and the end reinforcement grooves 9 The depth is greater than the depth of the secondary beam stand hole 6 . In a preferred solution, the main girder trough body 1 , the secondary girder frame hole 6 and the end reinforcing bar trough 9 are all located belo...

Embodiment 2

[0047] On the basis of Example 1, such as Figure 1~6Among them, an installation method using the above-mentioned multi-rib three-way prestressed prefabricated tank body steel bar installation platform includes the following steps:

[0048] 1. According to the structural size of the long-span multi-rib prefabricated tank body, design the detailed dimensions of the special platform for the multi-rib steel bar installation of the large-span tank body, and excavate the main beam tank body 1, the secondary beam platform hole 6 and the end according to the design requirements. Reinforcing groove 9 at the top; Precise setting out with a measuring instrument before excavation;

[0049] Preferably, the main beam tank body 1 is excavated mechanically, and the bench 2 in the secondary beam 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 b...

Abstract

The invention provides a steel bar installation rack and an installation method for a multi-rib three-directional prestress type prefabricated groove body. Main beam groove bodies are located on the two sides, a plurality of secondary beam rack holes perpendicular to the main beam groove bodies are formed between the main beam groove bodies, and secondary beam installing area racks are formed between the secondary beam rack holes; the depth of the two ends of each main beam groove body is larger than the depth of the middle of each main beam groove body, and end steel bar grooves are further formed close to the two ends of each main beam groove body, wherein the depth of the end steel bar grooves is larger than the depth of the secondary beam rack holes; and according to the installing sequence of main beams and secondary beams, the secondary beams, the main beams, side walls and bottom plates are installed sequentially, and then the whole transferring step is carried out. The installation method is matched with the specially-made steel bar installation rack, so that the construction efficiency of the multi-rib three-way prestress type prefabricated groove body is greatly improved, and the engineering progress is accelerated. By the adoption of the device and the method, a plurality of special-shaped structure steel bars of the main beams and the secondary beams of the single-truss groove body can be rapidly and efficiently installed in 96 hours, the operation conditions of the next working procedure can be prepared and the construction time of the groove body can be 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 prefabricated channel body steel bar 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 aqueducts. Therefore, 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 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...
