Problems solved by technology

The mechanical performance of the tenon-groove connection has certain limitations. Filling the joint with modified epoxy resin can meet the waterproof requirements in the northern region of my country, but in the southern region of my country, the precipitation is relatively large, and its waterproof performance remains to be investigated; while steel bars In addition to the difficulty in the positioning of steel bars in the method of sleeve and concrete secondary pouring, the secondary pouring of concrete will also cause problems such as prolonging the construction period and environmental pollution

Embodiment Construction

[0026] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] like figure 1 and figure 2 As shown, the connection structure of the vertical components of a prefabricated underground structure in the present invention includes an upper component 1 and a lower component 2, wherein the joint between the upper component 1 and the lower component 2 is a concave-convex structure, and the upper component 1 It is tenon-jointed with the lower side member 2, and the joint between the upper side member 1 and the lower side member 2 is filled with modified epoxy resin.

[0028] Several evenly distributed sleeves 3 are arranged in the lower member 2 of the present invention near the seam, and the lower steel bars 5 fixedly connected with the sleeves 3 are pre-embedded in the lower member 2 . In the upper side member 1, an upper side steel bar 4 is arranged at a position opposite to each sleeve 3, and one en...

Abstract

The invention discloses a connecting structure of an assembly type underground structure vertical member. The connecting structure comprises an upper component and a lower component which are connected in a mortise joint manner, and a plurality of sleeves are arranged in the lower component and close to the joint. An upper side steel bar is arranged in the upper component, at the position corresponding to each sleeve, and one end of the upper side steel bar extends into the sleeve. The connecting structure of an upper side steel bar inserting into a sleeve and the mortise connecting structureare combined, so that the bearing limitation of a simple mortise joint structure is overcome. Secondary pouring of concrete is avoided, the construction period is shortened, and the pollution to the environment is reduced.

Description

technical field [0001] The invention relates to a connection structure of assembled structural components in the field of civil engineering, in particular to a connection structure of vertical components of an assembled underground structure and a construction method thereof. Background technique [0002] The prefabricated underground station is built in the form of "building blocks": Compared with the traditional cast-in-place underground station, the beams, columns, side walls, roof, etc. of the prefabricated underground station are all prefabricated components. The components are assembled. It not only improves the production efficiency, but also ensures the construction quality of concrete; at the same time, it can reduce the use of on-site formwork, effectively saving construction materials and labor requirements; Noise pollution and environmental pollution. The construction technology of prefabricated underground stations provides an effective method to solve many pr...
