Description
Technical field
The utility model relates to the special construction apparatus of bridge-collision-avoidance wall assembling and dismantling mould, cantilever pouring concrete construction, the Shu Zhangla operation of case beam transverse prestress and hanging-outside decoration and constructions such as being used for high-speed railway, elevated road, is specifically related to a kind of agent structure that is used for Hanging Basket.
Background technology
At present when bridge-collision-avoidance wall assembling and dismantling moulds such as high-speed railway, elevated road, cantilever pouring concrete construction and Shu Zhangla operation of case beam transverse prestress and hanging-outside decoration and construction, adopt lands that steel pipe scaffold, suspended formwork support, A-frame form template supports or suspension type steel pipe template support etc. more.Land steel pipe scaffold to site requirements height, steel pipe consumption big and long construction period, can not be used for the bridge crossing construction or on stride the existing line construction; Suspended formwork supports and A-frame form template supports installation and removes difficulty, and security risk is big; Suspended formwork support need be when bridge deck concrete be mated formation layer construction pre-buried resistance to plucking reinforcing bar and with the steel pipe welding to prevent toppling of support system, its rigidity is little, cost is high, complex structure.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of agent structure that is used for Hanging Basket is provided, this agent structure that is used for Hanging Basket has the frame construction of a plurality of channel-section steels and i iron welding formation, and the connecting hole of symmetrical distribution is set on channel-section steel, and by angle steel and connecting hole bolt to constitute one, provide a kind of and assembled simply and the strong Hanging Basket agent structure of interchangeability.
This utility model purpose realizes being finished by following technical scheme:
A kind of agent structure that is used for Hanging Basket, described Hanging Basket is used for bridge-collision-avoidance wall assembling and dismantling mould, cantilever pouring concrete construction, the Shu Zhangla operation of case beam transverse prestress and hanging-outside decoration and construction, it is characterized in that: described agent structure comprises a plurality of frame constructions that are made of channel-section steel and i iron welding, the upper/lower terminal portion of described frame construction is equipped with flanged plate, be welded with the steel plate earrings of band circular hole on the described channel-section steel, described steel plate earrings is used for and the angle steel bolt, to connect a plurality of described frame constructions.
Described frame construction is for to be made of No. 10 channel-section steels of Q345 common low alloy structural steel and No. 8 i iron bond pads.
Described steel plate earrings is symmetrically distributed in described agent structure up and down.
The utility model has the advantages that: adopt the cradle structure of this agent structure simple, light and handy, assembly and disassembly are quick, are convenient to carrying, keeping; Structure is segmented to combine, and assembling is simple and interchangeability is strong.
Description of drawings
Accompanying drawing 1 is the utility model embodiment general assembly front view;
Accompanying drawing 2 is the utility model embodiment general assembly vertical view;
Accompanying drawing 4 is the utility model embodiment steel wheel seat structure schematic diagram.
The specific embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As shown in Figures 1 to 4, always represent respectively with reference to label 1-13: truss agent structure 1, hanging system 2, support and connection are 3, tail balancing weight system in equilibrium 4, Running System 5, upper cantilever i iron 6, square steel pipe 7, gripper shoe 8, wheel carrier 9, copper sheathing bearing 10, main shaft 11, roller 12, pin connect hole 13.
Referring to Fig. 1-4, the basic structure of cradle structure can be divided into truss agent structure 1 according to the purposes difference in the utility model, hanging system 2, tail balancing weight system in equilibrium 4, Running System 5 four major parts.
Wherein, agent structure 1 is as the body of cradle structure, and this agent structure is all installed and relied on to all the other hanging systems 2, tail balancing weight system in equilibrium 4 and Running System 5.
The body of agent structure 1 is a truss, No. 10 channel-section steels of material selection Q345 common low alloy structural steel and No. 8 i iron assembly welding shape structures in a row, and two ends are provided with flanged plate and mainly bear the vertical shear that hanging system 2 and tail balancing weight system in equilibrium 4 transmit up and down.Be welded with the steel plate earrings of band circular hole on No. 10 channel-section steels, its purposes be when assembly unit with in the steel bushing bolt-inserting hole on the bracing frame 3, it is stressed jointly that truss and bracing frame 3 are closely coupled together, the formation frame construction.All steel plate earrings on truss symmetry up and down all are used interchangeably.
Based on above-mentioned agent structure, the one side can be connected with hanging system 2, and opposite side adopts tail balancing weight system in equilibrium balanced load, and its lower end can be provided with Running System 5 whole moving and use, and below is described in detail for each composition that relies on agent structure:
Hanging system 2 is the groundwork device of cradle construction, its main material is selected square steel pipe 7 and upper cantilever i iron 6 for use, beam-ends square tube hollow pin connects, the change in location that pin connects hole 13 can make boom table regulate with the 10cm spacing, maximum lifting value is 60cm, to connect the spacing in hole 13 be 10cm to adjacent pin on both any two vertical direction, and the quantity that pin connects hole 13 is 7.Latch adopts 8.8 grades of M20 high-strength bolts to connect.The effect of steel I-beam end face eyelet supplies bracing frame and an angle steel to be connected to form four rows and hangs beam integral body.Steel I-beam bottom surface flange eyelet is used for being connected with flange bolt on the truss.
Tail balancing weight system in equilibrium 4 is mainly used in the platform that Hanging Basket overturning or slip resistance analysis safety is put the ballast material.Its material selection 100 * 50 * 5mm square steel pipe is hung rod member and is all adopted the flanged plate bolt to connect up and down, and platform structure adopts No. 10 common channel-section steels to be connected with the square steel pipe bolt.The suspension rod installation dimension all accomplishes to exchange.
Running System 5 is mainly whole the moving of Hanging Basket assembling back block construction and uses, and is installed on a plurality of steel wheel seat structures of the flanged plate both sides of truss agent structure 1 bottom surface for symmetry.Wherein the steel wheel seat structure includes one and is used for and gripper shoe 8 that the bottom surface bolt of truss agent structure 1 is fixing, gripper shoe 8 lower ends are welded with two parallel wheel carriers 9, the other end of wheel carrier 9 is respectively equipped with corresponding copper sheathing bearing 10, be set with a main shaft 11 in two copper sheathing bearings 10, be fixed with the roller 12 of a diameter 100mm on the main shaft.Adopting the reason of copper sheathing bearing 10 is that environment is abominable in bridge construction, plain bearing is prone to fault, and 10 body structures of copper sheathing bearing cause resistance big, and especially the confficient of static friction and the coefficient of kinetic friction differ bigger, make to have static easily, fixing characteristic.The grease of should annotating during the assembling of this steel wheel seat structure guarantees the lubricated parts depreciation that reduces, all can dismounting for ease of maintaining whole parts.
