Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
With reference to shown in Fig. 1, a kind of socket joint type key slot type construction formwork early-dismantling device provided by the invention, comprises adjusting screw(rod) 1, early dismantling head 2 and socket joint pedestal 3.
Described adjusting screw(rod) 1 peripheral hardware external screw thread, is arranged on vertical rod 12 top.
Described early dismantling head 2 comprises bracket 4 and bracket 5, and bracket 4 is in hollow cylindrical, and its axial centre runs through and is provided with the internal thread 6 suitable with adjusting screw(rod) 1 external screw thread.Bracket 4 top connects the bracket 5 of hollow cylindrical, and described bracket 5 is with bracket 4 is coaxial and internal diameter is equal, and bracket 5 external diameter is less than bracket 4 external diameter.During use, early dismantling head 2 is rotatably connected with adjusting screw(rod) 1 by internal thread 6, can adjust the position of early dismantling head 2 on adjusting screw(rod) 1 as required.Mostly use welding in prior art, this mode makes the direction of early-dismantling device in vertical rod 12 and position once determining, then can not change, can not adjust at any time in work progress according to construction demand.The present invention adopts the mode be threaded, can according to Specific construction needs, by screwing all number changes of screw thread, adjusts the position of early-dismantling device in vertical rod 12 and relative direction at any time.
Described socket joint pedestal 3 in hollow cylindrical, its internal diameter and bracket 5 external diameter suitable, bracket 5 can insert among socket joint pedestal 3.Socket joint pedestal 3 be circumferentially with cone-shaped nib 7, the shape of cone-shaped nib 7 is up-narrow and down-wide, inner narrow outer wide.
During use, buckle in cone-shaped nib 7 by cross bar 13 assembling with suitable conical socket, conical socket and cone-shaped nib 7 engage each other formation auxiliary connection.When not needing to use, conical socket is taken out from cone-shaped nib 7, does not need to use any screw or welding equipment, load and unload very convenient.
When the template gravity of early-dismantling device carrying is relatively little, the socket joint pedestal of minor diameter is adopted to bear.When the template gravity of early-dismantling device carrying is relatively large, adopts the socket joint pedestal of minor diameter to be difficult to bear, then need to adopt large diameter socket joint pedestal.Therefore, described bracket 5 bottom outer wall is provided with circular first step 8, and described bracket 4 top is connected with first step 8, and the external diameter of described first step 8 is greater than bracket 5 external diameter and is less than bracket 4 external diameter.When adopting the socket joint pedestal of minor diameter, socket joint pedestal 3 places first step 8 top; When adopting large diameter socket joint pedestal 3, socket joint pedestal 3 places first step 8 bottom.
Jacking of the prior art all can not install vertical rod 12 additional on jacking top, but often run in work progress and need to install vertical rod 12 additional to increase the situation of the load capacity of early-dismantling device in early-dismantling device bottom, therefore, the present invention is provided with circular second step 9 in bracket 4 lower inner wall axial running through, and the internal diameter of second step 9 is greater than bracket 4 internal diameter and is less than bracket 4 external diameter.When installing the vertical rod 12 of minor diameter additional, second step 9 top is placed in vertical rod 12; When adopting large diameter vertical rod, second step 9 bottom is placed in vertical rod.
Preferably, the two ends of described bracket 4 are provided with the handle 10 of rotatable early dismantling head, and rotary handle 10 drives early-dismantling device to move up and down along the external screw thread of adjusting screw(rod) 1, the height of adjustable early-dismantling device on adjusting screw(rod) 1.
Preferably, described bracket 5 is circumferentially with the through hole 11 of hollow out.This design at guarantee early dismantling head 2 while having enough intensity, rigidity and stability, can reduce the overall weight of early dismantling head 2, saves production cost, efficient energy-saving.
Preferably, the circumference of described socket joint pedestal 3 is evenly provided with four cone-shaped nib 7, and the shape of described cone-shaped nib 7 is up-narrow and down-wide, inner narrow outer wide.Four cone-shaped nib 7 make socket joint pedestal 3 can connect cross bar 13 at four direction, improve the practicality of early-dismantling device.
During use, adjusting screw(rod) 1 is arranged on scaffold upright rod 12 top, early dismantling head 2 is screwed in adjusting screw(rod) 1, it is outside that socket joint pedestal 3 is arranged on bracket 4, and socket joint pedestal 3 connects cross bar 13, for beam, the post of support shuttering.During the template needing adjustment to be positioned on cross bar 13, turning handle 10 drives early dismantling head 2 to rotate up and down in adjusting screw(rod) 1, and socket joint pedestal 3 moves up or down thereupon, cross bar 13 and template can be driven to move up and down, complete adjustment process.
The present invention adopts conical socket and cone-shaped nib 7 to engage each other the connected mode forming auxiliary connection, and this connection is reliable and stable, has and prevents collapsing de-function.When needs dismounting is of the present invention, only needs to cross bar 13 1 power vertically upward, namely can realize being separated of early-dismantling device and cross bar 13, efficiently simple to operate.Compared with connecting with fastener, the present invention's assembling, dismounting save time more than 90%, greatly reduce labour intensity, improve operating efficiency.Compared with early-dismantling device of the prior art, connecting portion contact area of the present invention is comparatively large, and friction factor is comparatively large, and its connected node shearing resistance, tension, measuring body ability are stronger, and the bearing capacity of whole connection system for guide rail is stronger, stability is higher.
The above is only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, and all technical schemes belonged under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be considered as protection scope of the present invention.
