Description

Bowl button self-locking multifunction scaffold

The utility model relates to a kind of building operations scaffold.

In recent years, the building operations scaffold has bigger development, especially the use of early removing system, make various support members, connector, regulating part all has new development, patent No. CN86201080 tooth button-type multifunction scaffold has been given priority to connector, utilize the engagement of tooth button, improved the stability of scaffold integral installation, but this profile of tooth bowl links fitting, the star cement in addition that is often fallen down above in practice of construction bonds, clear up these dry slags and need spend a large amount of work, not so can't re-use, this connected mode will be located accurately difficulty, and can only do stepping with a tooth pitch aspect horizontal, buckle can not be at an arbitrary position and column tight fit mutually, and the shaggy tooth processing cost of card bowl and buckle is higher.

The purpose of this utility model is:

1, provide a kind of have auto-lock function, taper surface contact, as the card bowl and the buckle of ricker and stull connector;

2, provide a kind of stable, highly can be freely regulated, parts are dismantled and assembled, interchangeability is good various support members.

Screw rod one end is connected and fixed with the pin-and-hole of cottor pin at pin-and-hole place and base steel pipe, and the screw rod other end inserts in the column tube, is held by the nut rotation, to form adjusting column of the present utility model.

With the pipe that has equidistant pin-and-hole that is welded with base plate, add a pair of fine setting screw rod, nut, can form the adjusting column of coarse adjustment of a kind of energy and fine tuning.

The utility model compared with the prior art, its advantage is:

1, is connected with buckle can self-locking for card bowl, the stability height, and energy location and installation quadrangle scaffold, not only accurately but also rapid; Again the polygon scaffold can be installed.

2, water body refuse not in the bowl button is exempted constructor's cleaning;

3, adopt several standarized components and indivedual special-purpose member promptly to can be assembled into multi-purpose support member; Reduce the cost of construction department.

The utility model is finished like this:

Scaffold of the present utility model is by column, be welded in card bowl and the clip that is enclosed within on the column on the column, be welded with the connecting rod (stull of buckle, diagonal brace), ladder, oblique scaffold floor, horizontal holder support, perpendicular holder support and adjustable column are formed, it is characterized in that: be welded with the card bowl on the column at a certain distance, buckle external surface on its inner surface and the connecting rod, the contact surface that is the two is the taper surface of angle together, this angle is one from the locking angle, during connection, in the cone tank between buckle insertion column and card bowl, the top-down application of force, buckle can be easily by wedging in cone tank.

The upper limb plane of card bowl is provided with four locating slots at right angle each other, and when being convenient to set up the quadrangle scaffold, stull and column can be located rapidly.

The following inner edge of card bowl is provided with several leaks, and the cement slurry of being convenient to fall in the card bowl spills.

Prevent that as hanging the scaffold time spent card bowl and buckle from taking off keeper of lock and being enclosed within on the column, its upper limb is a hypotenuse, constitute from the locking angle with its base, and the rotation clip, hypotenuse and the ejector pin that is welded on the column are right after and lock.

Horizontal, vertical holder support of the present utility model and adjusting column are that employing is modular, promptly adopt several same parts (as screw rod, nut, cottor pin etc.) and indivedual special-purpose member (as holder fastener, base etc.) to assemble as far as possible.

Holder support main body is a screw rod, and the screw rod upper end is connected and fixed with the pin-and-hole of holder fastener steel pipe at the pin-and-hole place with cottor pin, and insert in the column tube screw rod lower end, and withstands column tube to form horizontal, vertical holder support of the present utility model by the nut rotation.

Embodiment

Fig. 1 is each parts connection diagram of the utility model scaffold; By column 1, connecting rod (stull 2, diagonal brace 3), tiltedly scaffold floor 5 and ladder 4 etc. are formed, both sides link to each other with exterior wall 33 with the adjustable horizontal holder support of * 7; The bottom by 8 on adjustable column in the bottom surface; The top is by 6 templates of adjustable holder support; So that on template, carry out cast-in-situ floor or beam operation.Be welded with card bowl 9 on the column 1 at a certain distance; By connecting buckle 11 wedgings (Fig. 2) and linking to each other to form scaffold with connecting rod.

Be welded in the card bowl 9 (Fig. 3 on the column 1,4) inner surface and buckle 11 (Fig. 5,6) external surface, the contact surface that is both is the taper surface of tapering together, this cone angle is from the locking angle, the part that buckle 11 inserts card bowl 9 is the little down big conical ring of, buckle 11 inserts in the cone tank of

columns

1 and 9 in card bowl also the application of force from top to bottom, buckle 11 can be easily by wedging in card bowl 9 grooves, the upper limb plane 12 of card bowl is provided with four locating slots 13 at right angle each other, the width of locating slot 13 equates with the width of buckle 11, when setting up the quadrangle scaffold, can be rapid, correctly the location combines.This card bowl 9 and buckle 11 also can set up the scaffold of any limit shape (as hexagon).

The following inner edge 14 of card bowl 9 is provided with several leaks 15, is convenient to cement slurry and spills under leak, makes in the card bowl groove can not accumulate dry slag, removes the trouble of constructor's scarfing cinder from.

As preventing that card bowl 9 and buckle 11 from taking off keeper of lock 10 and being enclosed within on the column 1, its upper limb 34 is hypotenuses, constitute from the locking angle with its base, and rotation clip 10, hypotenuse is right after and locks with the ejector pin that is welded on the column 1.Generally speaking not by clip 10 but the self-locking angle lock of card bowl 9 and buckle 11 is reliable and stable.Just hanging scaffold and climbing the frame time spent,, can use clip 10 lockings for the self-locking that prevents card bowl 9 and buckle 11 comes off.

Horizontal, vertical adjustable holder support 6,7 (Fig. 7) of the present utility model and to regulate column 8 (Fig. 8) be to adopt modularly promptly adopt several same parts (as screw rod 19 (Figure 10), nut 21 (Figure 13,14) and cottor pin 22) and indivedual special-purpose member (to be assembled into the support member of difference in functionality as holding in the palm fastener 20 (Figure 11,12) base 24 (Figure 15,16) etc. as far as possible.

Holder support the 6, the 7th is made up of screw rod 19, holder fastener 20, nut 21 and cottor pin 22, screw rod 19 is the threadless screw rods in a top, there is a pin-and-hole 27 at no screw thread place, one spacing hole 23 is arranged at the bottom, the holder fastener 20 be welded by U-shaped steel plate 25 and steel pipe 31, have on the steel pipe 31 one with screw rod 19 corresponding pin-and-holes 27; Nut can have handgrip 32, be spun on the screw rod 19, the steel pipe 31 mat cottor pins 22 of screw rod 19 insertion holder fasteners 20 are connected to a fixed by the pin-and-hole 27 of the two, screw rod 19 inserts in the column tubes 1 certain-length and is held by nut 21, can make the length gradual change of screw rod 19 insertion column tubes 1 when swivel nut 21, can regulate height, in like manner can regulate horizontal holder support 7 to connect left and right sides side wall 33, spacing hole 23 inserts the sign that plays code length in the column tube 1 for screw rod 19.

The difference of regulating column 8 and

holder support

6,7 only is to change holder fastener 20 into base 24, and gets final product with holder support 6 inversions, and base 24 is to be welded by steel plate 30 and steel pipe 27.

When screw rod 19 being changed into equidistant pin-and-hole pipe 26 and a pair of screw rod 28, nut 29 (Figure 10) be about to form one can be slightly, the adjustable column 8 of thin tuning.
