Description
Technical field
This utility model relates to underground traffic road auxiliary device technical field, particularly relates to a kind of subway dispersing platform.
Background technology
Along with developing rapidly of national economy, the traffic of each big and medium-sized cities is the most crowded.The advantages such as subway is quick by feat of it, comfortable have been increasingly becoming the effective way solving these urban transport problems.In the subway station in nearly all city, subway train, personnel are the most intensive, taking, subway train runs into the attack of terrorism, transmission system breaks down or during the accident such as breaking out of fire, evacuate as early as possible the most rapidly, in an orderly manner from running tunnel inner tissue passenger, eliminate or reduce and cause because fire escape is obstructed injures and deaths to become crucial.
Traditional subway dispersing platform is based on concrete, general employing C40 concrete for making, thickness is 80 ~ 100mm, support uses traditional steel bracket, both has with the use of the problem existed: the evacuation platform weight of C40 concrete for making is big, installs more heavy, needs hanging device to carry out carrying and installation, outward appearance is coarse, ground freezing corrosion poor performance.Steel bracket is in metro environment, owing to underground humidity easily causes its phenomenon occurring that corrosion is ruptured.In addition to traditional concrete evacuation platform, have also appeared fiber glass resin evacuation platform in the recent period, it mainly solves evacuation platform and installs heavy problem, but simultaneously its loss of properties on aging, heatproof fire-protection rating are low, bear the negative blast ability within subway, easily causing evacuation platform to fly impact railcar in junction point breakage, safety problem highlights.Therefore, it is necessary to this is improved.
Utility model content
In view of this, the purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of excellent in durability, fire-protection rating are high, the subway dispersing platform of easy construction.
In order to solve above-mentioned technical problem, this utility model uses following scheme to realize:
A kind of subway dispersing platform, is installed on tunnel wall, and including the multiple supports poured by powder concrete, described support is connected with tunnel wall, and adjacent support is provided with the fixed thereto cover plate poured by powder concrete.
Support in this utility model and cover plate are powder concrete of the prior art and pour and form, powder concrete is the new material of a kind of superhigh intensity, high tenacity, high-durability, the evacuation platform making support and cover plate composition possesses on the premise of ensureing high intensity, weight can be greatly reduced so that construct more convenient, a dead lift, and, the support utilizing powder concrete to be prepared from corrodes more resistant to acid-alkali salt, and endurance quality is more preferable, it is to avoid the problem of conventional metals support corrosion.This utility model can greatly reduce the consumption of cover plate with two pieces of adjacent cover plates of support at same support.
Described support is triangular in shape, and what it contacted with tunnel wall is provided with for carrying out bolted bolt hole with tunnel wall, that it contacts with cover plate while being provided with for carrying out bolted embedded nut respectively with adjacent two cover plates.
The support support effect of triangle is more preferable, and more saves material.Support be bolted fixing with tunnel wall and cover plate, this connected mode is firm, convenient.By presetting preburied nut on support so that it is the most firm with the connection of cover plate, and junction can be prevented cracking.
Described support is hollow right angled triangle, and is built-in with the arrangement of reinforcement adapted with its shape in support, and the two ends of described arrangement of reinforcement form overlap joint at the hypotenuse of support, a length of 70 ~ 150mm of overlap joint.
Support is the right angled triangle of hollow and built-in arrangement of reinforcement, can reduce concrete material and also ensure that intensity.The two ends of arrangement of reinforcement are not only to connect the most permissible, but form certain lap of splice, the concrete of lap-joint can be prevented crack occur under using for a long time, through the substantial amounts of test of inventor, can obtain preferably effect in the range of 70 ~ 150mm.
The two ends that described cover plate is relative are provided with for carrying out bolted bar shaped bolt hole with support.
Owing to cover plate can cause the existence of tolerance due to a variety of causes during manufacturing, therefore, if the bolt hole on cover plate is circular, occur when then coordinating with the embedded nut on support that the probability that position offsets is bigger, therefore, in this utility model, cleverly the bolt hole on cover plate is set to bar shaped, therefore can preferably coordinate with embedded nut on support.
The thickness of described cover plate is 20 ~ 40mm.Cover plate of the present utility model uses powder concrete to prepare, and therefore under ensureing certain intensity, the thickness of cover plate can be reduced to 20 ~ 40mm, decrease the consumption of concrete, reduce weight so that construct more convenient.
Four angles of described cover plate are fillet.Fillet structure is possible to prevent scratch workman artificial lifting when, and fillet structure can effectively prevent coming off of corner cover plate is trampled when, and effect is better than right-angle structure.
Described cover plate is provided with multiple profit reduction and reserving hole that can be used for lifting.By retaining a percentage of the total profits for the enterprise's own use the setting in hole, artificial lifting is more convenient.
Being built-in with by the crisscross reinforcement network formed of long arrangement of reinforcement and short arrangement of reinforcement in described cover plate, described long arrangement of reinforcement adapts with the length of cover plate, and described short arrangement of reinforcement adapts with the width of cover plate.
Coordinated with powder concrete by crisscross reinforcement network so that the pressure-bearing effect of cover plate is better.The described here length adapted as arrangement of reinforcement is slightly less than the length of cover plate or both may be used of width.
The surface of described cover plate is provided with anti-skid design.The anti-skid design arranged adds the frictional force between human body, prevents from sliding into.
Compared with prior art, this utility model has the advantages that this utility model forms evacuation platform by the support made with powder concrete and arrangement of reinforcement and cover plate, overall construction design weight is low, convenient and quick construction, fire-protection rating height, acid and alkali-resistance salt corrosion, excellent in durability.
