Description
Technical field
The invention belongs to the structures such as xoncrete structure chimney, water tower and implement the technical field of high-altitude manual demolition, spy
Not there is provided a kind of concrete chimney dismantling operation platform, be safe and stable in the manual demolition of a kind of high-altitude
Operating platform, by low cost, high efficiency and the security reliability of door frame dismountable constitution realization high-altitude dismantling.
Background technology
The xoncrete structure structures such as chimney, water tower are because it is the highest, remove the features such as danger is big, Chang Cai at present
With directional blasting technology, and for special area, have inflammable and explosive danger or surrounding enviroment, close on residential block etc.
Factor must use manual demolition, practicality again, the one-tenth while of how accomplishing safe and reliable for safety prevention measure
This is low is a big technical barrier, and the present invention is by constructing high-altitude operation platform with door frame erection method, it is achieved high-altitude
Safe and stable property.
Summary of the invention
It is an object of the invention to provide a kind of concrete chimney dismantling operation platform, being technically characterized in that of solution:
By the component of simple portal-framed structure by assembled configuration one high-altitude dismantling operating platform.The present invention provides a kind of
Simple and reasonable, it is possible to effectively the danger of high-altitude manual work to be protected, ensured, meet high-altitude artificial
The requirement removed.
The present invention includes door frame (for many Pin door frame), tie-beam, base plate and protection network.Described door frame is unified chi
Very little, including channel-section steel support body, angle steel railing and hanger, support body, railing vertical rod, hanger, type of attachment is welding.
Door frame support body is ∏ shape, uses the welding of 14# channel-section steel, and door frame bottom is L-shaped hanger, uses 50 angle steel, and bolt is even
Connect, easy disassembly.Door frame top is guardrail upright pole, uses 50 angle steel, and bolt connects.During Demolition Construction, with 12
Pin door frame is angularly distributed on chimney wall, and door frame is connected with chimney wall jackscrew bar.Tie-beam spiral shell is used between door frame
Tethering and connect, tie-beam uses 14# channel-section steel to make.The process at the position that tie-beam is mainly connected with door frame, connection side
Formula uses high-strength bolt to be aided with quantity and the boundary of works area of steel wire rope scalable door frame.Hold according to loading angle, load
The feature of weight, typically uses the door frame quantity such as 6,9,12 to carry out assembly, notes order and connected mode in assembly,
In construction, the increase along with barrel diameter is adjusted by the form that is flexible coupling of steel wire rope, it is ensured that platform stabilization.
After connecting, upper berth platform floor, base plate uses the wooden scaffold board of specification 250mm*50mm, lays direction and company
Connect beam vertical, smooth laying, lay rear upper berth asbestos pad.Top guardrail upright pole with cross bar connect, cross bar with
Vertical rod chien shih is connected with, high 1.5 meters, and twice cross bar is brushed with the paint at red white interval on railing.Bottom hangs
Frame hangs double layer security protection network, one layer of big eye net, one layer of close mesh protection network.
(1) door frame: girder selects 14a channel-section steel notch vertical, and its cross section property is:
Area: A=18.51cm2
Inertia is away from Iy=53.2cm4
Rotary inertia: Wy=13.01cm3
The radius of gyration: iy=1.7cm
Sectional dimension: b=58mm, h=140mm, t=9.5mm
(2) tie-beam: select material identical with door frame girder, the channel-section steel of specification.For connecting platform center
The support of platform floor.
(3) platform floor: select the wooden scaffold board (Masson Pine, Lignum seu Ramulus Cunninghamiae Lanceolatae) that building site is conventional, specification 250mm*50mm.
(4) protection network: use double layer security net, 100 square centimeters of one layer of big eye protection network 800 mesh, one layer of close mesh
Safety net 2000 mesh/100 square centimeter.Thus rubble can be stopped, the falling of the object such as fragment of brick, splash.
The form component that the present invention utilizes door frame, tie-beam to use bolt, steel wire rope to connect by certain angle is torn open
Except operation platform, can be effectively improved safety and the efficiency of construction of high-altitude manual demolition, this platform has simple in construction
Rationally, assemble in operation, design margin evaluation height and easily operated feature of constructing, it is adaptable to high-altitude coagulation
The manual demolition construction of soil chimney.

Detailed description of the invention
The present invention includes door frame (for many Pin door frame), tie-beam, base plate and protection network.Described door frame is unified chi
Very little, including channel-section steel support body, angle steel railing and hanger, support body, railing vertical rod, hanger, type of attachment is welding.
Below in conjunction with the accompanying drawings, the present invention is described in further detail.
(1) assemble shown in schematic diagram such as Fig. 2 operating platform, the making of this operating platform, installation, predominantly door frame
Assemble, be generally 6,9,12 Pin according to the rational quantity of the diameter matches of chimney, angularly assembled, connected mode
For connecting with tie-beam and steel wire rope, bottom boarding two-layer.
(2) as shown in Fig. 3 operating platform profile, door frame holds out against fixing with jackscrew bar with chimney wall when assembling, as
Shown in Fig. 1 door frame detail drawing, above door frame, 50 angle steel are the support of platform guardrail, connect into 1.5 with angle steel bolt above
The high guardrail of rice.Door frame lower outer is 50 angle steel hangers, end boarding, plug-in close mesh protection network, prevents falling rocks.
Top dress discharging rod and supervising device.
(3), during barrel Demolition Construction, when diameter becomes big with the reduction of barrel, font door frame should be increased open,
Increasing operating platform simultaneously, during in order to ensure to increase door frame, make the stability of whole platform, its measure is for utilizing group
During dress, the hole of φ 50 in the middle of former door frame cross-arm, wears the steel wire rope of three road φ 14, first unclamps two therein, another
Root, as safety rope, treats that two steel wire ropes stay enough scopes, by two fag end lockings, then unclamps as insurance
Restrict one and utilize same method by tight for this cord lock.Then the door frame of addition is evenly arranged along barrel girth, and will
Operating platform scaffold board is completed, is tied, various equipment, check and accept on inspection after can come into operation.
