Sample, when the upper half bar that the lower half bar of a upright bar unit piece is inserted into another upright bar unit piece, lower half bar is fully inserted to
Installation can be completed using its gravity, between very convenient and upright bar unit piece in the inside of half bar, and the two is seated cooperation
Bond strength it is high.The length of the upper half bar 11 and lower half bar 12 is 300mm.The total length of upright bar unit piece 10 is 600mm,
When two upright bar unit pieces are mutually inserted, the lower half bar of a upright bar unit piece is fully inserted into the upper half of another upright bar unit piece
Bar, that is, often increase a upright bar unit piece, the length of upright bar is increased by 300mm, meets the modulus requirement in building height direction,
The radical of suitable upright bar unit piece can be selected as needed.The mounting hole includes the first mounting hole 14, and the disk buckles 13
For annular disk button, four the first mounting holes 14 are evenly provided with along peripheral direction, first mounting hole 14 is circular through hole,
The mounting hole further includes the second mounting hole 15, is equipped with one second mounting hole 15 between two neighboring first mounting hole, and described the
Two mounting holes 15 are arc-shaped through-hole.Under normal conditions, the screw rod 24 at 20 both ends of cross-bar unit part is inserted into the first mounting hole 14
, if building is odd-shaped cross section, screw rod 24 can be inserted into the second mounting hole i.e. arc-shaped through-hole, utilize the arc of through-hole
Structure adjusts the setting angle between cross bar and upright bar, so as to adjust the angle of scaffold to meet the need of special-shaped building
It asks.
As shown in Figure 5 and Figure 6, the first side pole 21 in the cross-bar unit part 20,22 and second side pole 23 of connecting rod be all
For round steel pipe, the inside of first side pole 21 is equipped with internal thread, and the screw rod 24 is fitted vertically in the first side pole 21
One end, the connecting rod 22 are integrally formed part and the equal length of the first linkage section and the second linkage section, the first linkage section
Outside is equipped with external screw thread, and internal thread is equipped on the inside of the second linkage section, external screw thread is equipped on the outside of the insertion end of second side pole 23,
First side pole, 21 and first linkage section is spirally connected fixation by internal and external screw thread, and second linkage section and the second side pole are inserted
Enter end or the second linkage section of a connecting rod and the first linkage section of another connecting rod to be spirally connected fixation by internal and external screw thread.It is horizontal
The minimum length of bar unit part 20 for successively by 21, connecting rods 22 of first side pole and 23 grafting of the second side pole and
Into, will be first by multiple 22 phase interfix of connecting rod by increasing the number of connecting rod when the length of cross-bar unit part to be increased
Intermediate bar is formed after connecing, then assembles to form cross-bar unit part by the first side pole, intermediate bar and the second side pole.The second end
The inserting paragraph and fixed section of bar 23 are integrally formed the equal length of part and the two, and the outer diameter of the insertion end is slightly less than fixed section
Internal diameter, the screw rod 24 is fitted vertically one end far from inserting paragraph in fixed section, the inserting paragraph and the first linkage section
Outer diameter is equal, and the internal diameter of the fixed section and the second linkage section is equal.The length of first side pole 21 is 300mm, connecting rod
22 length is 600mm and the length of the second side pole 23 is 600mm.Cross-bar unit part 20 divides for lateral cross-bar unit part and longitudinal direction
Cross-bar unit part, longitudinal cross-bar unit part are mutually inserted by first side pole, two connecting rods and second side pole,
Lateral cross-bar unit part forms intermediate bar and a second side pole phase by the connecting rod of first side pole, three or three or more
Mutual grafting forms, and can select the radical of connecting rod as needed so as to form the different lateral cross-bar unit part of length, often increase
Add a connecting rod, the length of cross bar is increased by 300mm, meets the modulus requirement of building width direction.
The installation process of the present invention：An as shown in Figure 1, part (in scaffold frame body of the present embodiment for scaffold frame body
Interbed), in the structure of cuboid：A height of 3m, width 1.2m, a length of 3.6m combine shape by upright bar, counterbracing 30 and cross bar
Into by being mutually inserted to form upright bar by multiple upright bar unit pieces 10, lower half bar 12 is directly inserted into upper half bar 11 during grafting
In both can, the height of each layer of scaffold is 3m in the present embodiment, i.e. each layer of scaffold is mutual by 10 upright bar unit pieces 10
Grafting forms；Cross bar is made of cross-bar unit part 20, and cross-bar unit part 20 divides for lateral cross-bar unit part and longitudinal cross-bar unit
Part, longitudinal cross-bar unit part are mutually spirally connected by 21, two connecting rods 22 of first side pole and second side pole 23, i.e.,
The width of this scaffold is 1.2m, and lateral cross-bar unit part is by 21, four connecting rods 22 of first side pole and a second end
Bar 23 is mutually spirally connected, i.e., each lateral cross-bar unit part length is 1.8m, and the length of this scaffold is the multiple of 1.8m；Often
One layer of cross-bar unit part is equipped with every the height of 1.5m, during installation, the both ends screw rod 24 of cross-bar unit part 20 is inserted into upright bar respectively
(when building is polymorphic structure, screw rod can be inserted into the second mounting hole 15, led in the first mounting hole 14 that unit piece disk is buckled
The arcuate structure of the second mounting hole is crossed to adjust the setting angle between cross-bar unit part and upright bar unit piece so that entire foot hand
The angle of frame meets the demand of special-shaped building), then locked by nut 25, and cross-bar unit part and upright bar unit piece are consolidated
Fixed connection, and counterbracing 30 is installed between upper and lower two lateral cross-bar unit parts, by the both ends screw rod 24 of counterbracing 30
It is inserted into the first mounting hole 14 for buckleing of upright bar unit piece disk respectively, then by nut check, and by counterbracing 30 and upright bar
Unit piece is fixedly connected, and two counterbracings are arranged in a crossed manner, forms " X " font, so as to play lateral support to scaffold and enclose
The effect of shield improves the security performance of scaffold, and the present invention is easy for installation, easy to disassemble and transports, and use scope is wide.
It should be pointed out that for those of ordinary skill in the art, without departing from the inventive concept of the premise, may be used also
To make several modifications and improvements, these belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with
