Description
Technical field
The utility model relates to a kind of assembly for scaffold for building, relates more specifically to a kind of sleeve pipe for scaffold.
Background technology
In current scaffold industry, part for connecting upright pole is generally the internal diameter seamless steel pipe larger than vertical rod external diameter or the external diameter pipe less than vertical rod internal diameter, seamless steel pipe is welded on vertical rod pipe, and little pipe uses bolton after inserting vertical rod pipe after needing punching.But these two kinds of mounting means location are all cumbersome, and after installing, because inside does not have positioning bar, stress point is eccentric, there is gap, easily cause and rock between upper and lower vertical rod, and then cause scaffold unstable, and security performance is also had a greatly reduced quality.
Utility model content
The purpose of this utility model is to provide a kind of sleeve pipe for scaffold, thus solve vertical rod of the prior art install inconvenience, connect insecure, cause the defect that scaffold security performance is not high.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions:
A kind of sleeve pipe for scaffold is provided, described sleeve pipe is used to any two vertical rods of connecting pin hand cradle, described sleeve pipe has the tubular wall of surrounding cavity, described wall has at least one pair of to be arranged symmetrically with centered by the center longitudinal axis of described cavity and the bolt hole running through described wall, the inner side of described wall also has boss circumferentially, axially spaced apart at described wall of described boss and described bolt hole.
Described wall has two to being arranged symmetrically with the bolt hole running through described wall centered by the center longitudinal axis of described cavity.
Four described bolts hole in the circumferential uniform intervals are opened.
Described boss radially to extend internally a width towards the center longitudinal axis of described cavity on the inner side of described wall, and described width is preferably 4 ~ 5mm.
Described bolt hole at described sleeve pipe along its intermediate section axially, described boss is near a tail end along its axis of described sleeve pipe.
The inner side of described wall also has and axially extends from the wall between described bolt hole and boss the guiding rib ending at described boss, described guiding rib has the spigot surface that relatively described wall tilts to extend.
Described guiding rib is four, and preferably, every bar guiding rib is aimed in the axial direction with described bolt hole respectively, but in fact also can misalignment.
According to the utility model, provide a kind of sleeve pipe simultaneously with bolt hole and boss, ensure that the Fast Installation of vertical rod when scaffolding erecting, and by arranging guiding rib at internal surface of sleeve pipe, to guarantee between vertical rod and vertical rod without acceptance of persons, without rocking, the scaffold firm stable built, safety is higher.

Fig. 1 is the sectional view of the sleeve pipe according to a preferred embodiment of the present utility model;
Fig. 2 is the sectional view under the sleeve pipe as shown in Figure 1 using state when connection two vertical rods;
Fig. 3 is the top view of structure shown in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, provide preferred embodiment of the present utility model, and be described in detail, enablely understand function of the present utility model, feature better.
As shown in Figure 1, be sleeve pipe 1 according to a particularly preferably embodiment of the present utility model.This sleeve pipe 1 can be used to any two vertical rods 2,2 ' (see Fig. 2) of connecting pin hand cradle.This sleeve pipe 1 has the tubular wall 12 of surrounding cavity 11, this cavity 11 vertically extends along a center longitudinal axis 13, this wall 12 has two to being arranged symmetrically with the bolt hole 14 running through described wall 12 centered by center longitudinal axis 13, adjacent any two bolts hole in these four bolts hole 14 are in 90 ° to be evenly arranged in the circumferential.The inner side of this wall 12 also has boss 15 circumferentially, axially spaced apart at wall 12 of boss 15 and bolt hole 14.As shown in fig. 1, bolt hole 14 at described sleeve pipe 1 along its intermediate section axially, described boss 15 is near a tail end along its axis of described sleeve pipe 1.The inner side of wall 12 also have four guiding ribs 16 aimed in the axial direction with four bolts hole 14 respectively, this guiding rib 16 axially extends from the wall 12 between described bolt hole 14 and boss 15 and ends at boss 15, and there is the spigot surface 161 of relatively described wall 12 inclination extension, thus form the cavity of convergent near contiguous boss 15.
Preferably, boss 15 radially to extend internally a width towards the center longitudinal axis 13 of described cavity 11 on the inner side of described wall 12, and described width is 4 ~ 5mm.
According to above preferred embodiment of the present utility model, article four, guiding rib 16 is aimed in the axial direction with four bolts hole 14 respectively, but only unrestricted as an example, even if be also enough to realize technique effect of the present utility model because guiding rib 16 is not aimed in the axial direction with bolt hole 14.
According to above preferred embodiment of the present utility model, this sleeve pipe 1 has four bolts hole 14, but only unrestricted as an example, because two bolts hole 14 are also enough to realize technique effect of the present utility model.Arrange 4 bolts hole only conveniently to install, make vertical rod rotate some angles a little and get final product erection bolt, save the set-up time.
According to a preferred embodiment of the present utility model, use any two vertical rods 2 of this sleeve pipe 1 connecting pin hand cradle, 2 ', in order to realize any two vertical rods 2, the connection of 2 ', vertical rod 2, also should have a pair installing hole 21 corresponding with the bolt hole 14 on sleeve pipe 1, specifically as shown in Figure 2 on 2 '.
With reference to figure 2 ~ Fig. 3, concrete using method is as follows: first, the below of a vertical rod 2 ' from sleeve pipe 1 is inserted, to the top of this vertical rod 2 ' against the boss 15 inside the wall 12 of sleeve pipe 1, then girth welding is carried out along this sleeve pipe 1 with the end of the junction of vertical rod 2 ', as shown in black triangles region in Fig. 2, after having welded, sleeve pipe 1 and vertical rod 2 ' form as one.
Then, the top of another root vertical rod 2 from sleeve pipe 1 is inserted, under the guide effect of spigot surface 161 being positioned at the guiding rib 16 inside the wall 12 of sleeve pipe 1, vertical rod 2 move down until the bottom of vertical rod 2 be resisted against sleeve pipe 1 wall 12 inside boss 15 stop, adjustment vertical rod 2 while vertical rod 2 is inserted, align with the bolt hole 14 on sleeve pipe 1 to make the installing hole 21 in vertical rod 2, subsequently bolt 4 is inserted the bolt hole 14 on sleeve pipe 1, the installing hole 21 in vertical rod 2 successively, then mounting nuts 5 is fastening.So, namely achieve by a sleeve pipe the connection of two vertical rods.
According to the utility model, provide a kind of sleeve pipe simultaneously with bolt hole and boss, ensure that the Fast Installation of vertical rod when scaffolding erecting, and by arranging guiding rib at internal surface of sleeve pipe, be convenient to vertical rod and insert along spigot surface direction, concentricity deviation is little, guarantee top vertical rod and below vertical rod between without acceptance of persons, without rocking, the scaffold firm stable built, safety is higher.
Above-described, be only preferred embodiment of the present utility model, and be not used to limit scope of the present utility model, above-described embodiment of the present utility model can also make a variety of changes.Namely every claims according to the utility model application and description are done simple, equivalence change and modify, and all fall into the claims of the utility model patent.The not detailed description of the utility model be routine techniques content.
