Problems solved by technology

The traditional construction method is to open two small holes according to the fixed position of the Hafen groove 6 on the formwork that needs to be poured into the concrete foundation, and then pass the binding wire through the small holes and wrap it around the C-shaped groove body 1 so that the Hafen groove 6 However, during the process of pouring and vibrating concrete in the formwork, the tie wires are prone to loosening, which causes the position of the HALFEN groove 6 to shift, and sometimes even breaks away from the formwork surface

Embodiment Construction

[0021] Now take a rail transit project as an example to illustrate: this project is an urban rail transit demonstration line, in which the rail-bearing beam body is a concrete foundation, and 5830 HALFEN groove groups need to be embedded as important connection points for the installation of rail structures. Parts equipment and facilities, the accuracy of the installation elevation and position of the HALFEN trough group are important guarantees to ensure the safe and stable operation of the train in the later period. Reliable and works well.

[0022] The device and construction method for accurately installing the HALFEN tank provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The same reference numerals are used for the same parts as in the prior art.

[0023] like figure 2 and figure 1 As shown, the device for accurately installing the HALFEN groove provided by the present invention in...

Abstract

The invention discloses a device for accurately installing a Halfen groove and a construction method. The device comprises a positioning rod piece, a T-shaped toothed bolt, a nut and plywood. The construction method comprises the steps of welding and fixing the Halfen groove group; determining the positions of the template and the Halfen groove group; the Halfen groove group is in reinforced connection with the template; and demolding the Halfen groove group to remove accessories and the like. According to the device for accurately installing the Halfen groove and the construction method, operation is convenient and fast, facilities are simple, the device and the formwork are connected to form a whole, the tedious procedure of adjusting and checking the position of the Halfen groove is omitted, manpower and material resources are saved, dismounting is convenient, part of components can be recycled for multiple times, and high popularization performance is achieved.

Description

technical field [0001] The invention belongs to the technical field of rail transit engineering construction, and in particular relates to a device and a construction method for accurately installing a HALFEN trough. Background technique [0002] In recent years, with the rapid development of my country's rail transit industry, most domestic subway projects often use HALFEN troughs as pre-embedded troughs to prepare for the installation of external structures. figure 1 Front view of a commonly used HALFEN trough structure. like figure 1 As shown, the HALFEN groove 6 is mainly composed of a C-shaped groove body 1 and a plurality of anchor legs 2 whose one end is connected to the groove bottom of the C-shaped groove body 1 . In order to ensure subsequent structural installation requirements, the notch and channel of the C-shaped groove body 1 on the HALFEN groove 6 need to be flush with the outer surface of the concrete foundation after the formwork is removed, and the ancho...
