Description
Technical field
The utility model relates to the urban traffic field, specifically is the armrest seat that bar is installed on a kind of subway evacuation platform.
Background technology
At present, city underground is because factor such as the volume of the flow of passengers is big, escape condition in tunnel is poor, escape distance, escape time are few the serious accident that the dead group of group hinders just very easily occurs in case fire occurs.And evacuation platform is set is the effective ways of alleviating fire incident in the subway.Consider that for safety factor the height that must be suitable for people's grasped above evacuation platform is provided with the bar that extends along the length of tunnel direction, and on the bar at a certain distance as 1.5 meters be provided with one bar be fixed on armrest seat on the tunnel wall.
The armrest seat of traditional subway evacuation platform as shown in Figure 1, it comprises the seat of honour and following, the described seat of honour is made of the upper cross plate 101 that connects as one and first circular arc cover 102, described following by the holder 103 that connects successively, lower cross plate 104 and second circular arc cover 105 constitute, described holder 103, lower cross plate 104 and second circular arc cover 105 are one, described upper cross plate 101 is provided with the hole of passing for bolt 106, also be provided with corresponding with upper cross plate 101 hole of passing for bolt 106 on the described lower cross plate 104, described holder 103 is provided with two expansion bolt via holes 107, the described seat of honour and following the glass fiber reinforced plastic by the SMC compacting constitute described upper cross plate 101, lower cross plate 104, the thickness of first circular arc cover 102 and second circular arc cover 105 is all less than the thickness of holder 103.
People are prefabricated hole for the expansion bolt on tunnel wall earlier, the expansion bolt that passes the expansion bolt via hole by two then and screw in the hole for the expansion bolt of tunnel wall is fixed on holder on the tunnel wall, then bar is matched with down in second circular arc cover of seat, then first circular arc hitch is combined in second circular arc and puts, at last with the bolt locking seat of honour of passing hole on upper cross plate and the lower cross plate and following.
There is following defective in the armrest seat of the subway evacuation platform of above prior art: at first, because this armrest seat is a glass-reinforced plastic material, the armrest seat of this material can only adopt mould pressing process to make, and the metal die cost of mould pressing process is very high, open a cover metal die and must spend several thousand yuan, so the manufacturing cost height; Secondly, the intensity of glass fiber reinforced plastic and hardness are all undesirable, for the armrest seat intensity hardness that makes glass fiber reinforced plastic reaches designing requirement, each parts of this armrest seat particularly holder must do very abundant, so just certainly will more take material, further increase cost, and need a plurality of armrest seats in a tunnel, these armrest seats stack up, and the material that expends is huge; Once more, fix an armrest seat and need two cover expansion bolt assemblies (generally comprising dormant bolt, expand tube, plain washer, spring pad and hex nut), this just need make a call to two hole for the expansion bolts on tunnel wall, article one, all armrest seats in the tunnel stack up, the quantity of the expansion bolt assembly that consumes is big, and the punching process wastes time and energy, loaded down with trivial details inconvenience.
The utility model content
The technical problems to be solved in the utility model is that the armrest seat of the low subway evacuation platform of a kind of cost is provided.
Technical solution of the present utility model is, a kind of armrest seat with subway evacuation platform of following structure is provided, it comprises the holder that is linked in sequence into an integral body, first transverse slat, starting stave, upper cross plate, the circle cover of band opening, lower cross plate and following riser, the described upper end of riser down can push against the junction at first transverse slat and starting stave, be equipped with the hole that supplies bolt to pass of position correspondence on described upper cross plate and the lower cross plate, described holder is provided with an expansion bolt via hole, described holder, first transverse slat, starting stave, upper cross plate, the circle cover of band opening, lower cross plate is the identical metalwork of thickness with following riser.
After adopting above structure, the armrest seat of the utility model subway evacuation platform compared with prior art has the following advantages:
People are a prefabricated hole for the expansion bolt on tunnel wall earlier, again bar is passed the circle cover of armrest seat, to be fixed on the holder of an expansion bolt via hole on the body of wall by one group of expansion bolt assembly then, pass on upper cross plate and the lower cross plate corresponding hole with a bolt at last and screw, the junction and the circle that make the upper end of riser down push against at first transverse slat and starting stave overlap the armrest seat banding, the installation of single armrest seat.
Because round cover, lower cross plate and the following riser of described holder, first transverse slat, starting stave, upper cross plate, band opening are the identical metalwork of thickness, like this, this armrest seat can be stamped to form with the metal sheet such as the steel plate of a block length, and Sheet Metal Forming Technology is without the die sinking tool, much lower with respect to its cost of mould pressing process, so this armrest seat cost is low; And because this armrest seat is a metalwork, its intensity hardness is big, so each component thickness of this armrest seat is thin, materials are economized, and further reduce cost; Again because metalwork armrest seat intensity hardness is bigger, can only be provided with an expansion bolt via hole on the holder, and, the inventor learns through testing repeatedly, by a fixing bar of a plurality of armrest seats, each armrest seat only depends on once the cover expansion bolt assembly is fixing can satisfy intensity, the requirement of hardness, like this, with respect to the original armrest seat of fixing by two cover expansion bolt assemblies, this armrest seat can guaranteed strength and hardness, saved a cover expansion bolt assembly again and made a call to a hole for the expansion bolt less, and whole armrest seats in a tunnel stacks up, abridged expansion bolt huge amount, so saved great amount of cost, and compared with prior art, this armrest seat be installed on tunnel wall, beaten the hole for the expansion bolt of half less, so save trouble and labor is more installed more convenient.
