Problems solved by technology

The safety gate cannot be fixed directly to the existing platform slab by penetrating bolts or chemical anchors
Since the prefabricated platform slab adopts multi-piece splicing method, and the structural size is very small (the thickness of the slab is only about 40mm, which cannot even meet the requirements of the current concrete structure code), it cannot meet the structural requirements of the installation, and the actual structural construction conditions exist in various positions and sizes. The installation error and structural deformation will cause the penetrating bolts or chemical anchor bolts to fail when they meet the slab seams, and the slab ribs will be damaged when they meet the slab ribs, which will endanger the safety of the platform slab
Therefore, the current platform slab cannot be directly used to install and fix safety doors, and must be reinforced and transformed

Embodiment 1

[0021] The technical solution disclosed by the present invention is: to reinforce the subway platform through a reinforcement device to increase the load capacity of the subway platform. The specific method is to set the reinforcement device at the place corresponding to the installation position of the column of the subway safety door. The reinforcement device includes: a top steel plate 24, The main column 29, the auxiliary support 27, and the two ends of the auxiliary support 27 are respectively hinged with the main column 29 and the top steel plate 24.

[0022] In order to reduce the damage to the platform caused by the vibration generated when the subway train is running, and also to provide suitable pre-tightening force for the reinforcing device and the platform, a shock absorbing pad 23 is provided between the top steel plate 24 and the platform plate 22 .

[0023] For ease of installation, the height of the main column 29 is designed to be smaller than the distance bet...

Embodiment 2

[0033] A reinforcement device for a platform, comprising: a first shock-absorbing pad 2, an upper adjustment member 3, a lower adjustment member 4, and a support base 5; a first shock-absorption pad 2 is provided between the platform board 1 and the upper adjustment member 3 for Reduce the impact of the vibration generated when the train is running on the platform, and at the same time provide an appropriate pre-tightening force between the reinforcement device and the platform plate 1; the upper adjustment member 3 and the lower adjustment member 4 are connected by adjusting bolts; the lower adjustment member 4 and the supporting base 5 is fastened by bolts, and the support base 5 is fixed on the foundation by expansion bolts. The whole device plays a supporting role to the platform board 1, increases the strength of the platform board 1, and can meet the requirement of installing the safety door on the platform strength. Because the structure of the device is simple, the con...

Embodiment 3

[0048] A reinforcement device for a platform, comprising: a first shock-absorbing pad 2, an upper adjustment member 3, a lower adjustment member 4, and a support base 5; a first shock-absorption pad 2 is provided between the platform board 1 and the upper adjustment member 3 for Reduce the impact of the vibration generated when the train is running on the platform, and at the same time provide an appropriate pre-tightening force between the reinforcement device and the platform plate 1; the upper adjustment member 3 and the lower adjustment member 4 are connected by adjusting bolts; the lower adjustment member 4 and the support base 5 is fastened by bolts, and the support base 5 is fixed on the foundation by expansion bolts. The whole device plays a supporting role to the platform board 1, increases the strength of the platform, and can meet the requirement of installing the safety door on the strength of the platform.

Abstract

The invention discloses a subway platform reinforcing construction method; a reinforcing device comprises a first damping pad (2), an upper adjusting member (3), a lower adjusting member (4), and a support pedestal (5); the features are that the first damping pad (2) is arranged between a platform plate (1) and the upper adjusting member (3); the upper adjusting member (3) is fixed on the platform plate (1) through expansion bolts; the upper and lower adjusting members (3,4) are connected through adjusting bolts; the lower adjusting member (4) is connected with the support pedestal (5) through bolts; the support pedestal (5) is fixed on the ground foundation through expansion bolts. According to the method, the pre-tightening force between the reinforcing device and the platform plate is adjusted through the structure of the reinforcing device. The reinforcing device is simple in design, convenient in construction, low in reconstruction cost, short in construction period, thus having small influence on subway operation.

Description

technical field [0001] The invention relates to a reinforcement construction method for a subway platform. Background technique [0002] China's subway has been in operation for more than 40 years. Now the passenger flow of many subways far exceeds the original design capacity, and safety accidents occur frequently, which poses great hidden dangers to the normal operation of the subway. Therefore, it is necessary to install safety doors to ensure operation and train parking. Run on time. Due to various considerations such as station structure and operational impact, it is only suitable for installing half-height security doors. However, at the time of design of the current platform board, the half-height safety door equipment installation interface is reserved at the end of the platform, and the strength cannot meet the installation requirements of the half-height safety door equipment. [0003] Safety door load requirements are: [0004] The impact load of the crowd on t...
