Abstract

The utility model relates to a quick disassemble type adjustable bracket. The quick disassemble type adjustable bracket is composed of a top plate (1), a supporting rod (11), a nut (12), a pin shaft (13), a supporting seat (14) and a pin chain (15), wherein, the middle of the supporting rod (11) is provided with a quadrate pin hole (16) with an inclined shape, and the supporting seat (14) is supported by the pin shaft (13) inside the quadrate pin hole (16) with an inclined shape. The utility model has double functions that a post head can be early disassembled, and the supporting seat can be adjusted. The quick disassemble type adjustable bracket not only can early disassemble a mould, but also can adjust supporting height.

Description

Quick disassemble type adjustable bracket

The utility model relates to civil works template scaffold technical field.

When cast-in-place concrete floor or concrete roof construction, for consumption and the shortening construction period that reduces template, supporting beam, normally the quick detach bracket is installed on the top of bearing support or cramp bar, as early tearing column cap (China Patent No.: 89208740.4), the early stage dismounting to accelerate turnover of template and supporting beam used open.Owing to early tear the complex structure of column cap open, the processing cost height, function singleness, and because contact area and frictional force between support bracket and the pin plate are all bigger, and labour intensity is higher during use is used dumb grade and is affected application.

The purpose of this utility model just is to provide a kind of simple structure, uses flexibly and has concurrently early tears the quick detach bracket of column cap and two kinds of functions of adjustable bracket open.

Existing accompanying drawings structure of the present utility model.

Accompanying drawing 1 is a diagrammatic sketch of early tearing column cap in the prior art open, is made up of top board (1), cramp bar (2), base plate (3), inserted link (4), pin plate (5) and support bracket (6).Accompanying drawing 2 is early to tear the elevation of column cap cramp bar (2) open, in both sides, cramp bar (2) middle part a bracket (9) is arranged respectively, and a limiting plate (10) is arranged at the top of cramp bar (2).Accompanying drawing 3 is lateral views of cramp bar (2).During use, the inserted link (4) of cramp bar (2) bottom is inserted in the steel pipe (8) on bearing support top, base plate (3) is bearing in above the steel pipe (8); Pin plate (5) is installed in above the bracket (9), pin plate (5) is supporting support bracket (6) again, and the supporting beam of template (7) is bearing on the support bracket (6).Remove or when removing supporting beam (7) in early days, with adz-eye hammer hammering pin plate (5) and it is dropped to above the base plate (3), supporting beam (7) and the template above it are landed in succession and are removed, and top board (1) is still supporting floor at this moment.

Accompanying drawing 4 is diagrammatic sketch of the present utility model, is made up of top board (1), cramp bar (11), nut (12), bearing pin (13), supporting base (14) and pin chain (15).

Accompanying drawing 5 is elevations of cramp bar (11).

Accompanying drawing 6 is lateral views of cramp bar (11).

The middle part of cramp bar of the present utility model (11) has that flat declivity gradient is the square oblique shape pin-and-hole (16) of θ on one, θ＜9 degree; Pin-and-hole (16) width is C, C=10-30mm; Height one side is h for the H opposite side, and H＞h, H=15-40mm.The top that cramp bar (11) is positioned at pin-and-hole (16) does not have screw thread, and screw thread is arranged at the bottom; Supporting base (14) is identical with the base plate of multi-functional jacking (China Patent No. is 92202553.3), and top is rectangular, and (bottom is rounded and several ribs are arranged for a * b) or square, the one group of bossed location of opposite side dop wherein; The be square bearing pin (13) of oblique shape, the big end size of an end size is little, and gradient is the same with the gradient of pin-and-hole (16).Being positioned at the big end of bearing pin (13) size has a pin chain (15) to connect together with supporting base (14).

The utility model inserts the lower end of cramp bar (11) in the steel pipe (8) on bearing support top in use, and nut (12) is bearing on the steel pipe (8); Insert in the pin-and-hole (16) bearing pin (13) and locking simultaneously, bearing pin (13) is gone up surface bearing and supporting base (14), and supporting base (14) is gone up surface bearing and supporting beam (7).When supporting beam (7) is removed or is removed in early days, with the little end of adz-eye hammer hammering bearing pin (13) size, bearing pin (13) is gone out cramp bar (11) by hammering when, supporting base (14) drops to earlier on the nut (12), supporting beam (7) and template are landed in succession, and top board this moment (1) is still supporting floor.

The utility model is torn column cap open with morning and is compared, and has following advantage:

At first, the utility model is screwed and nut (12) is installed that the lifting by adjusting nut (12) during use just can reach the purpose of regulating the bracket effective height because cramp bar (11) is positioned at the bottom of pin-and-hole (16).Therefore, the utility model is early torn open the function of column cap except that having, and also has the function of adjustable bracket simultaneously.Secondly, contact area between bearing pin of the present utility model (13) and the supporting base (14) is very little, only be 1/10th of contact area between the pin plate (5) of early tearing column cap open and the support bracket (6), therefore to tear the used hammer force of column cap open much smaller than Zao for the hammer force of using when dismounting supporting beam (7).Once more, the utility model is owing to simple structure, and processing cost is low, weight saving 10-15%.So, the utlity model has significant technical economic benefit and social benefit.

Claims

1, a kind of adjustable quick dismountable bracket of being made up of top board (1), cramp bar (11), nut (12), bearing pin (13), supporting base (14) and pin chain (15) is characterized in that:

A. there is the be square pin-and-hole (16) of oblique shape of flat declivity at cramp bar (11) middle part, and the height of pin-and-hole (16) one sides is greater than opposite side;

B., the bearing pin (13) of one square oblique shape is arranged in the pin-and-hole (16), and an end size is bigger, and an end size is less, and its gradient is the same with the gradient on pin-and-hole (16) base;

C. there is a pin chain (15) to be connected together between bearing pin (13) and the supporting base (14);
