Description

Join plate for steel tube scaffold

What the utility model was related is a kind of junction plate of steel pipe scaffold, uses this junction plate that the steel pipe of two intersections is connected scaffold, is widely used in building engineering field or other supports.

Using support in the past construction work, is that steel pipe is directly welded, and makes many identical frame purlins, and then overlapping being socketed to form.Make support, cost height in this way, transportation volume is huge, can not change with the requirement of site operation, and must leave the gap at cover contact and bolt tie point place, because this gap exists, the easy pine of cover contact strides, and causes contingency.At present, in construction work, use scaffold, adopt connection fastener that vertical rod, cross bar and base are constituted the space lattice structure,, connect like this that the required connector of scaffold is many, time-consuming to bring many inconvenience to construction because the rigidity difference often needs many diagonal brace pull bars.

The junction plate that the purpose of this utility model is to provide steel pipe scaffold to use constitutes the space lattice structure with column steel pipe, crossbeam steel pipe and the base that intersects, and it is hard as the rigidity as the crystal that it is had.

Inventive concept of the present utility model is that all not in same plane, its intersection steel pipe therebetween a slice square plate is used as connector for column steel pipe center line and crossbeam steel pipe center line, and by U bolt, nuts and taper washer make it constitute rigid unitary.

Below in conjunction with accompanying drawing, junction plate of the present utility model is specified:

The utility model steel pipe scaffold uses junction plate, is two kinds of square or rectangulars, and it is stamped to form by steel plate.The main performance of its junction plate is four edges edge with junction plate as diagonal brace, and four angles are as tie point.The shallow hook of same direction bending 90 degree of corresponding two angles on diagonal, corresponding two angles also bend the shallow hook of 90 degree in the other direction on another diagonal equally, and the hook root strikes out concavo-convex saddle type, and concave surface is bill dorsad.See Fig. 1 for details.

For satisfying the requirement of construction work, according to construction requirement, the utility model provides several difform junction plates;

1, two quadrature steel pipe junction plates (1),---it is for connecting two root post steel pipes (7) and the 90 degree uses of crossbeam steel pipe (8) quadrature.This junction plate is square steel plate, and two jiaos is axis with the diagonal respectively on its diagonal, bends two pairs of shallow hooks respectively in pairs in the other direction, and hook root place forms concave surface bill dorsad, is beneficial to U bolt, and the contact surface of steel pipe and junction plate fits like a glove.When connecting two plain edition column steel pipes (7) and crossbeam steel pipe (8), to be parallel to junction plate two diagonal way, the both sides of being close to junction plate (1), each is located with four jiaos of saddle type hook root positions (18) of junction plate (1) with four U bolts (4), cooperate U bolt cap (11) and taper washer (9) and U bolt saddle type base (13), in the middle of junction plate clamping two steel pipes.When connecting special steel pipe,, with taper washer (9) steel pipe is connected with the reinforcement of junction plate (1) by four U bolts (4) and U bolt cap (11) being drilled with eight (four pairs) taper bolt holes (5) near (1) four bill place of junction plate.Be drilled with four (two pairs) bolts hole near the junction plate center simultaneously.Connect for the longitudinal and transverse quadrature of steel pipe.Certainly, the diameter of bolt hole should be slightly larger than the diameter of U bolt, so that U bolt passes through smoothly.See Fig. 2,3.

2, two oblique steel pipe junction plates (2),---it designs for two oblique steel pipes.This junction plate (2) be shaped as rectangle, according to the construction needs, the diagonal angle that rectangle is two jiaos is designed to 60 °, 45 ° and does not wait specification, it is identical that square steel plate structure is described in the structure of its junction plate and front.See Fig. 4 for details.

3, three quadrature steel pipe junction plates (3),---it designs for horizontal direction two intersections crossbeam (8) and column steel pipe (7) closely cooperate.It is used near adjustable column footing (15) and joint portion, adjustable column termination (14) strengthens column steel pipe (7).This junction plate is that a slice is converted into L shaped square plate, on column steel pipe (7) connection vertical line, be drilled with a pair of bolt taper hole for U bolt (4) connection, on horizon, be drilled with X-axis and Z-direction, the U bolt (4) that crossbeam steel pipe (8) is connected, two pairs of parallel bolt taper holes.Same by U bolt (4), U bolt cap (11) and taper washer (9) are fastenedly connected, for this junction plate (3) and portraitlandscape steel pipe are coincide, the L shaped square plate angle of this junction plate is designed to circular arc type, two pairs of parallel bolt taper hole centers are stamped into saddle type on horizon, strengthen the contact surface of column steel pipe (7).See Fig. 6.

When connecting overweight steel pipe, the utility model also provides a kind of overweight steel pipe support junction plate (12), and it is a slice square steel plate, and on the diagonal four jiaos, be drilled with the taper bolt hole in pairs, and strike out concavo-convex saddle type in this screw center, replace shallow hook.The column steel pipe can be with splicing sleeve (10), strengthens rigidity.See Fig. 5 for details.

When the little extremely square junction plate (1) of distance takes place to disturb with junction plate (1) between column steel pipe (7) and column steel pipe (7), the utility model provides ultra dense collection steel pipe support junction plate (17) to replace junction plate (1), this ultra dense collection steel pipe support junction plate is the polygon-octagonal steel plate, and each is spent according on one side every 90 mutually in its four pairs (two pairs) taper bolt holes.See Fig. 7.

As for above-mentioned various junction plate thickness, it depends on and intersects the diameter of steel pipe, and the utility model will be according to diameter of steel tube and on-the-spot needs, and the design series of products use for the user.

During use, choose four groups of U bolts (4), two groups of U bolts (4) are enclosed within on the column steel pipe (7), two groups of U bolts (4) are enclosed within on the crossbeam steel pipe (8) in addition, select a slice junction plate for use, steel pipe (7) is located at the hook root saddle type position (18) of junction plate, lock together with U bolt (4) and junction plate, equally with steel pipe (8) near the hook root saddle type position of junction plate reverse side, lock together.If when connecting special steel pipe, the U bolt taper hole near four jiaos can be passed through U bolt (4), U bolt cap (11) and taper washer (9) and U bolt saddle type base (13) are firmly strengthened it and are connected.Other tie point situations are identical.Column steel pipe (7) is also identical with cant beam steel pipe (6) oblique situation.Three crossing situations of two horizontal gird steel pipes and column steel pipe, the front illustrates.So use difformity junction plate provided by the utility model to constitute the steel pipe scaffold of space lattice formula, it has hard as the rigidity as the crystal.See Fig. 7.Because of whole tie points are closely to encircle mutually, taper washer (9) has been eliminated the gap between U bolt (4) and taper bolt hole (5) in addition, power on any direction in space is applied on any steel pipe, be distributed at once on all structures, the distortion of any steel pipe will not take place.

By the steel pipe scaffold of assembling above, adopt electric wrench, will shorten the engineering time.As seen this scaffold is except that selecting different junction plates for use, and 90% parts can use general purpose accessory.It is strong to the utlity model has rigidity, and material is simple, and standardization a bit all is chosen as tie point arbitrarily on the steel pipe, connects the influence that support is not subjected to concavo-convex ground and slope.In building engineering field, this junction plate has use value widely.
