Abstract
An expansion joint of adjustable and fast-dismounted top plate support is made in the way that of two square steel pipes are covered and connected with each other; one end of the inner sleeve is wedge-shaped; the bottom side of the other end is provided with a fixing pin hole; a metal wedge matches with the inner sleeve; a screw cap is fixed below one end of the wedge shape of the inner sleeve; the metal wedge is provided with a hole, through which an adjusting screw rod is screwed to the screw cap; both ends of the bottom side of the outer sleeve are respectively provided with a fixing pin hole. During use, adjust the inner and outer sleeves of the expansion joint to an appropriate length, and insert the fixing pin holes on the bottom side of the inner sleeve and that of the outer sleeve into the fixing pins on the adjustable and fast-dismounted expansion joint of top plate and the vertical post top plate. The expansion joint has simple design and is convenient to adjust. The joint only can be when the remaining length is smaller than the standard length of transverse beam. Therefore, together with the ''adjustable and fast-dismounted top plate support'', the expansion joint can meet the design requirements for any room.
Description
One, technical field
The utility model relates to a kind of aid of roof supporting when making cast-in-situ floor in the building operations.
Two, background technology
Building scaffold is the important tool in the building operations, and fastener type steel pipe scaffold is the most frequently used instrument of building trade at present.But there is following problem in actual applications in fastener type steel pipe scaffold: 1. safety assurance is relatively poor.The main fixedly steel pipe of fastener that relies in work progress during situation generations such as, stripped thread loosening if any the fastener silk, causes potential safety hazard probably; 2. positioning performance is relatively poor.The workman is easy to take place the error of floor absolute altitude in the construction location, as it is loosening fastener to occur, and it is sagging also can floor to take place, and serious also can cause quality problems; 3. man-hour, amount was big.Rely on fastener to fix steel pipe in the construction fully, difficulty is big, man-hour amount big, human and material resources all have very big waste; 4. serious waste timber.Set up roof timbering with fastener type steel pipe scaffold, need a large amount of flitches to fix wooden form in the construction, the frame construction building of a building area 5000m2 will consume tens cubes of push rod, flitches, the serious forest reserves that consume country; 5. form cycling rate is low, can not stripping less than the freezing period of building standard regulation.So the inventor has designed a kind of " adjustable quick dismountable top plate bracket ", number of patent application is 200620130483.8, can effectively address the above problem.But because the design size size in room is all different, the clamped beam of standard can not satisfy the requirement of reality construction in the top plate bracket, if with once cutting once, has not only wasted raw material but also time-consuming taking a lot of work.
Three, summary of the invention
The technical problems to be solved in the utility model is: design a kind of expansion coupling that matches with inventor's design " adjustable quick dismountable top plate bracket ", to solve the defective that it exists.
The technical scheme that solution the utility model technical problem is taked is: connected together by two rectangular steel tubes and make expansion coupling, inner sleeve one end is the timber wedge shape, and a fixed pin holes is arranged on the other end bottom surface, and a metal timber wedge cooperates with inner sleeve; On below inner sleeve timber wedge shape one end, fixedly mount a silk cap, a hole is arranged on the metal timber wedge, the hole that the adjustment screw mandrel passes the metal timber wedge is spun on the cap; Be equipped with a fixed pin holes at two ends, outer tube bottom surface.When needing to adjust, inner sleeve is released forward, made expansion link meet the requirements of size, screw the adjustment screw mandrel, the metal timber wedge will face down along the timber wedge of inner sleeve and move, and fills up the gap of outer tube the inside, and firmly is fixed on the outer tube the inside.
To adjust screw mandrel more stable when the work in order to make, can be on the inner sleeve bottom surface, establish a guide thimble between silk cap and the metal timber wedge.
Good effect of the present utility model is: simplicity of design, use easy to adjust, can be from 10mm to adjusting arbitrarily the standard crossbeam length, that is to say, as long as residue length can be used this expansion coupling less than standard crossbeam length, just can satisfy the designing requirement in any room like this with " adjustable quick dismountable top plate bracket " supporting use of inventor's design.
Four, description of drawings
Accompanying drawing 1 is a structural representation of the present utility model; Accompanying drawing 2 is user mode figure of the present utility model.
Five, the specific embodiment
Accompanying drawing 1 is a structural representation of the present utility model, and it is connected together by two rectangular steel tubes and makes, and the total length after outer tube 2 long 450mm, inner sleeve 4 long 500mm, inner sleeve 4 all release from outer tube 2 is 900mm.Inner sleeve 4 one ends are the timber wedge shape, a fixed pin holes 3 is arranged on the other end bottom surface, a metal timber wedge 9 cooperates with inner sleeve 4, the gradient of timber wedge end is identical with the gradient of metal timber wedge 9 on the inner sleeve 4, with metal timber wedge 9 domatic corresponding one sides are planes, silk cap 6 of welding has a hole on below inner sleeve 4 timber wedge shapes one end on the metal timber wedge 9, and the hole that adjustment screw mandrel 8 passes metal timber wedge 9 is spun on the cap 6; Respectively be provided with a fixed pin holes 1,5 at two ends, outer tube 2 bottom surface.To adjust screw mandrel 8 more stable when the work in order to make, can be at guide thimble 7 of welding on inner sleeve 4 bottom surfaces, between silk cap 6 and the metal timber wedge 9.
Fig. 2 is user mode figure of the present utility model, if standard fixed beam 13,14 length is 1220mm, if the residue length of limit portion is 850mm, clamped beam 13 not up to standard, during 14 length, that is to say in the time of to use the standard fixed beam, can be with the inner sleeve 4 of this expansion coupling 10 to extrapolation, when the total length of inner sleeve 4 and outer tube 2 equals 850mm, adjust screw mandrel 8 with long spanner is screwed, metal timber wedge 9 is moved down and firmly is fixed on outer tube 2 the insides, promptly make expansion coupling 10, during use, the fixed pin holes 3 on expansion coupling 10 inner sleeves 4 bottom surfaces and the fixed pin holes 5 on the outer tube 2 are plugged on the steady pin 11 on " adjustable quick dismountable top plate bracket " 12 and the vertical rod jacking 15.
