Description
Technical field
The utility model relates to a kind of subway platform bracing means.
Background technology
China's subway has been opened four more than ten years of operation, present many subway passenger flows super original design capacity far away, and safety misadventure takes place frequently, and causes and large hidden danger to the safety of the normal operation of subway, so need install safety door additional, ensures operation, Train Stopping running on time.Now, because being limited to the consideration of the each side such as station structure, Influence to operation, be only suitable in half-height safety door is installed.But platform is with the reserved half-height safety door equipment mounting interface in end when design for existing platform plate, and intensity cannot meet half-height safety door equipment installation requirement.
Safety door load requires:
The impact load of crowd's opposite house body: 1500N(at 0.2S in the time, acts in the scope of 100mm * 100mm) structure is without permanent deformation.
The extrusion load of crowd's opposite house body: 1500N/m(is apart from platform decorative cover 1.1m eminence).
Half-height safety door bears blast: ± 600Pa(standard value).Seismic condition: basic seismic design accekeration 0.20g; Basic intensity of earthquake is 8 degree.
Level of vibration: BS4675 first order level.
Many old station platform plate structures are prefabricated platform plate substantially.Prefabricated platform plate gauge lattice are unidirectional prestress trough plate (part is circular hole slab), the wide 890m of plate, and plate stitches wide 20mm, the about 110mm of construction and decoration thickness.Platform plate length in safety door fitting limit mostly is 1970mm, and one end is supported in brick wall (cantilever span 300mm), and the other end is put on agent structure bottom girder.Circular hole slab thickness is 130mm, the high 150mm of trough plate main rib, the high 100mm of inferior rib, thickness of slab 40mm.Safety door is approximately stressed: vertical power F1=5KN; Horizontal force F2=5KN; Prolong line direction horizontal force F3=1KN; Moment M=7KN.m.
According to < < urban railway system platform shielding door systems technology standard > > (CJJ183-2012) requirement, platform plate is calculated.Some stations are owing to being prefabricated platform plate, and period of service reaches 40～50 years, and difficulty of construction is relatively large.Safety door cannot directly be fixed on present situation platform plate by penetrating the mode of bolt or chemical anchor bolts.Because prefabricated platform plate adopts polylith connecting method, and scantling of structure is very little, and (thickness of slab is 40mm left and right only, even cannot meet existing code for design of concrete structures requirement), cannot meet the structure requirement of installation, and that practical structures Construction Condition exists is multiple, installation error and the structural distortion of position dimension, cause penetrating bolt or chemical anchor bolts and run into plate seam and lost efficacy, run into rib of slab and can damage rib of slab, jeopardize platform plate safety.Therefore, present situation platform plate can not directly be used for installing fixedly safety door, must carry out strengthening reconstruction.
Summary of the invention
In order to make platform that safety door can be installed, must reinforce subway platform, to guarantee the safety of facility and passenger in the work progress of safety door is installed and during metro operation.The utility model provides a kind of device of reinforcing of subway platform.
This subway platform bracing means, comprising: the first cushion blocking 2, upper adjustment member 3, lower adjustment member 4, base for supporting 5; Between platform plate 1 and upper adjustment member 3, be provided with the first cushion blocking 2; Upper adjustment member (3) is fixed on platform plate 1 by expansion bolt; Upper adjustment member 3 is connected by adjusting bolt with lower adjustment member 4; Lower adjustment member 4 is with base for supporting 5 by bolted, and base for supporting 5 is fixed on ground by expansion bolt.
The impact of vibrations on platform that produce during for further reduction train driving, is provided with the second cushion blocking 6 between lower adjustment member 4 and base for supporting 5.
Because building element tolerance is larger, for convenient, to install, lower adjustment member 4 is provided with mounting hole, and the mounting hole of upper adjustment member 3 is made as the slotted hole of vertical direction, is convenient to the setting height(from bottom) of adjustment member 3 in a big way;
In order to strengthen supporting role, upper adjustment member 3 is comprised of steel plate, main support, auxiliary stand, and its light plate is in over water placing flat, and auxiliary stand tilts to be arranged between main support and top steel plate.
In order to obtain better support effect, the auxiliary stand on upper adjustment member 3 and top steel plate angle are that 45 degree are between 60 degree.
In order to arrange the fixing upper bolt of adjusting member 3 and lower adjustment member 4, there is the space that lays mounting hole auxiliary stand lower end and the main support lower end adjusted on member 3.
Bracing means is generally arranged on the place corresponding with safety door column installation site, considers that the long or passenger flow volume of platform building time exceeds the situations such as former design value is more, also can according to circumstances, correspondingly improve the density of setting of bracing means.
The technical solution of the utility model simplicity of design, practical; The bracing means reliable operation of making according to the utility model, and setting range is large, and easy for installation.Can meet the requirement of strength that old subway platform installs safety door additional completely, reduced to greatest extent original platform plate infringement simultaneously, and the easy construction of whole subway platform improvement project, improvement expenses is relatively low, and the duration is shorter, less on metro operation impact.
