Embodiment 2

[0089] In this example, if image 3 As shown, the difference from Embodiment 1 is: between the first trolley and the trolley support top template 2-1 installed on the second trolley and between the third trolley and the fourth trolley The trolley support top formwork 2-1 installed on the trolley is connected through the grooved combined formwork, and the lower part of the first vertical formwork segment in the grooved combined formwork is passed through the first The two vertical formwork sections 12 are connected to the bottom connection formwork 2-21; the assembled formwork 25 is passed between the second trolley and the trolley support top formwork 2-1 mounted on the third trolley to connect.

[0090] In this embodiment, the structures and connections of other parts are the same as those in Embodiment 1.

Embodiment 3

[0092] In this example, if Figure 4 As shown, the difference from Embodiment 1 is that in this embodiment, the number of the longitudinally moving trolleys 1 is 5, that is, N=4. The 5 longitudinally moving trolleys 1 are respectively the first from left to right. One car, second car, third car, fourth car and fifth car. That is to say, the first trolley is the left trolley, and the fifth trolley is the right trolley. Between the first trolley and the trolley support top formwork 2-1 installed on the second trolley and between the fourth trolley and the trolley support top formwork installed on the fifth trolley 2-1 are connected through the single formwork 24, the second trolley and the trolley mounted on the third trolley support the top formwork 2-1 and the third trolley It is connected with the trolley support top formwork 2-1 installed on the fourth trolley through the grooved combined formwork, and the first vertical formwork section in the grooved combined formwork T...

Abstract

The invention discloses a combined lining formwork trolley for a subway station. The combined lining formwork trolley comprises a movable supporting system and a formwork assembly, wherein the movable supporting system is composed of a plurality of longitudinal moving trolley bodies capable of moving in the subway station under construction, the formwork assembly is arranged on the movable supporting system and conducts molding construction on secondary linings of the subway station under construction, and the longitudinal moving trolley bodies are arranged in the same horizontal plane from left to right; the formwork assembly comprises a combined top formwork and two side formworks, the two side formworks are symmetrically arranged on the left side and the right side of the combined top formwork respectively, and the combined top formwork comprises a plurality of trolley supporting top formworks mounted on the longitudinal moving trolley bodies respectively and middle connecting formworks connected between every two trolley supporting top formworks which are adjacent in a left-right mode; the middle connecting formworks are horizontal connecting formworks or groove type combined formworks. The combined lining formwork trolley is simple in structure, reasonable in design, easy and convenient to use and operate, good in usage effect and capable of solving the problems that construction is complex, the construction efficiency is low, the occupied space is large and the use effect is poor when a traditional subway station lining construction method is adopted.

Description

technical field [0001] The invention belongs to the technical field of subway station lining construction, and in particular relates to a combined subway station lining formwork trolley. Background technique [0002] With the acceleration of urbanization and the popularization of automobiles, urban traffic problems have become increasingly prominent. Rail transit is a better solution to long-term congestion. At present, many large and medium-sized cities in China have begun to build a large number of underground railways. The development of China's subway construction has become impossible. Against the tide of history. [0003] As an important part of subway construction, the construction technology of the secondary concrete lining of the main structure of the station is the decisive factor. The subway station is underground and has a large buried depth. The design service life is 100 years, and the span is about 19 meters. There are longitudinal beams and columns in the mi...
