Description
Technical field
The present invention relates to building safety technical field of construction, are concretely related to a kind of tower crane occasional passage and its installation
Method.
Background technology
Tower crane is the common heavy mechanical equipment in construction site, also known as " derrick crane ", passes through a section spreading
(referred to as " standard knot ") is a kind of on building site for hanging the raw material of the constructions such as working reinforcing bar, wood stupefied, concrete, steel pipe
Essential equipment；Adhesion tower-crane is one kind relatively common in numerous tower crane types, since building height is higher,
It is rigidly connected between tower crane and building to reinforce the stability of derrick crane, generally abuts proposed building and arrange.
Since tower crane distance structure floor is there are a certain distance, tower body can rise with the rising of story height, tower
Department is on and off duty daily to need included vertical cat ladder among tower crane tower body manually to be climbed, and there is great safety is hidden
Suffer from, especially when sleety weather, hot weather, severe cold weather, cat ladder bench freezes, is moist, driver's climate condition,
The influence of the factors such as own bodies and mental status easily causes safety accident during upper and lower climbing.
In order to save the climbing time of tower department or more tower crane, safety accident caused by avoiding climbing is needed in tower crane tower body
An occasional passage is suitably highly set up between fabric structure, tower department first reaches from the stair or construction elevator of building
The floor of occasional passage is set up, then goes to tower crane tower body from occasional passage, then climb remaining height along vertical cat ladder and arrive
Up in tower crane cockpit, the occasional passage set up constantly up is promoted with the rising of depth of building, greatly reduces tower
The height of vertical cat ladder is climbed by department, to reduce security risk.
Traditional occasional passage is generally set up using steel pipe, and channel is usually chosen in attachment rack position, using steel pipe
Easy channel is set up into, scaffold board is laid on the lateral steel pipe of the bottom of the channel and is passed through for tower department, it is logical that steel pipe sets up safety
The major defect in road is：The channel needs repeatedly to be set up with the rising of tower body and story height, while setting up need to be in height
Aerial to carry out operation, operation is got up inconvenience, and there are certain security risks, while between every tower crane and building
Distance be not fixed, the occasional passage of regular length cannot be met the requirements.
For the problems in the relevant technologies, currently no effective solution has been proposed.
Invention content
Therefore a kind of tower crane occasional passage of present invention proposition and its installation method, for solving in above-mentioned background technology
Problem.
The technical proposal of the invention is realized in this way：A kind of tower crane occasional passage, including set tube coupling and intubation save, and
Set tube coupling and intubation section by alternately it is interspersed splice is connected, folding guard rail is provided on described sleeve pipe section, on the folding guard rail
Be hinged with railing pipe, be arranged with telescoping tube in the railing pipe, and railing pipe replace with telescoping tube interspersed connection and set tube coupling and
Intubation section corresponds to.
Further, described sleeve pipe section includes the cylindrical chute casing with coulisse, and is welded in two cylinders
The first netted channel plate between sliding slot casing, intubation section include intubation, and the intubation lower section is provided with connecting pole, two
The second netted channel plate is provided between the connecting pole, the intubation matches setting with cylindrical chute casing.
Further, cylindrical chute casing end is provided with limited location snap ring, and the intubation is provided at both ends with and limits
The limit protrusion of position snap ring cooperation.
Further, it is welded with respectively with the contact position of cylindrical chute casing and circle below the described first netted channel plate
The parallel square steel of cylindricality sliding slot casing is equidistantly welded with three mutually isostructural square steel between two square steel.
Further, two connecting pole lower ends are welded with square steel, and three are equidistantly welded between two square steel
Mutually isostructural square steel.
Further, including occasional passage end is hinged with safety door, and the safety close to the side of building floor layer
It is provided with locking device between door and railing pipe, the locking device includes loop chain and lock.
Further, further include be welded with latch hook in cylindrical chute casing end close to standard section of tower crane side, and
Lantern ring is respectively welded in the cylindrical chute outside of sleeve of the two neighboring set tube coupling in centre position.
Further, the folding guard rail is that diamond shape folds push-pull configuration, and the diamond shape being spaced folds the end of push-pull configuration
It is point articulated on adjacent railing pipe.
A kind of installation method of tower crane occasional passage, includes the following steps：
S1, measure tower crane between building building at a distance from, measurement distance is appropriately extended, and records；
S2, on the ground, by set tube coupling and intubation section cooperation telescopic adjustment, being adjusted to the data recorded in S1, making
Occasional passage is sling by lantern ring with tower crane, when occasional passage is transported to corresponding floor by tower crane, first by one end of occasional passage
It is held in floor plates, then adjusting the angle makes latch hook be hooked on the cross bar of standard knot, and tower crane unclamps channel, releases lantern ring,
Installation is complete；
S3, it checks installation, determines that occasional passage installation is stablized, come into operation.
By above disclosure, beneficial effects of the present invention are：The present invention saves the side of splicing using set tube coupling and intubation
Formula can be adjusted arbitrarily by being used cooperatively for cylindrical chute casing, intubation, folding guard rail and railing pipe and telescoping tube
Length meets construction required distance；Simple in structure, demolition, installation are convenient, reusable, set up, solve existing without repeating
Super High tower crane walkway setting up and in demolishing process exist construct it is cumbersome the problems such as, improve the number of turnover, save
A large amount of manpower, eliminates security risk when installing and dismounting, effectively increases the safety of tower on tower crane driver, design science
Rationally, suitable construction promotes the use.
