In conjunction with accompanying drawing, the utility model is further described.
Embodiment 1
This utility model includes column, platform fine strain of millet, ladder beam, diagonal brace, it is characterised in that:
See Fig. 3 and Fig. 4, also include bonding formula draw-in groove 1；The described formula that bonds draw-in groove 1 is for set arc in a plate 1-1
It is formed through gap 1-4 between the edge of two terminations of hole 1-2, described arcuate socket 1-2 and the plate 1-1 of corresponding side；This
Arcuate socket 1-2 in example is preferably with excellent arcuate socket.Described gap 1-4, totally in splayed, is positioned at eight within plate 1-1
The two ends of the gap 1-4 of font respectively and form partition portion between two terminations of arcuate socket 1-2；Described arcuate socket 1-2 with
Telescopic spring pin 1-6 it is respectively equipped with on the termination in two partition portions between gap 1-4；
The rear wall of the formula that the bonds draw-in groove 1 that two are parallel transversely disposed is fixed on column 8 and forms one group and bond formula card slotware；
Two spaces bonded between formula draw-in groove 1 may be used for dodging other movable part.
See Fig. 2 and Fig. 6, the upper and lower both sides of described terraced beam 6 respectively with the inner edge pin joint of adjacent landing beam 4；Platform
The top of the exterior bottom pin joint diagonal brace 5 of the outside of beam 4；The diagonal brace roller bearing 7 of the affixed lateral arrangement in bottom of diagonal brace 5；Platform
The inside bottom of the outside of beam 4 is respectively and fixedly connected with the landing beam roller bearing 71 of a lateral arrangement；
It is respectively equipped with upper and lower two groups on column 8 below corresponding each landing beam 4 and bonds formula card slotware；Described platform
The two ends of beam roller bearing 71 are respectively nested in one group of two arcuate socket 1-2 bonding formula card slotware of top；The two of diagonal brace roller bearing 7
In holding one group that is respectively nested in lower section two the arcuate socket 1-2 bonding formula card slotware；
Seeing Fig. 5, described pin joint uses rotary shaft connecting pin 2；Described rotary shaft connecting pin 2 is pin 2-1's
One end fixed head 2-2, the other end of pin 2-1 is along the radial direction apertured of pin 2-1, a bolt type steady pin 2-4 mid portion
Through described hole, bolt type steady pin 2-4 is respectively arranged at two ends with nut and is positioned at the outside of pin 2-1, uses this rotation
The more convenient installation of rotating shaft connecting pin 2.
Seeing Fig. 1, such landing beam 4 constitutes folding stair part with ladder beam 6 pin joint, and folding when to install this
During stair part, just landing beam roller bearing 71, diagonal brace roller bearing 7 are connected, when to dismantle with corresponding formula draw-in groove 1 inlay card that bonds respectively
Time, as long as landing beam roller bearing 71 is taken out in the corresponding arcuate socket 1-2 bonding formula card slotware with diagonal brace roller bearing 7, should
Folding stair part can migration it place installation.In this example, landing beam 4 is played good supporting role by diagonal brace 5, dismounting
After, diagonal brace 5 is pinned on landing beam to be received together with folding stair part, in order to migration is again repeated utilization at it.
In this example between landing beam 4 and column 8, and it is respectively adopted between diagonal brace 5 and column 5 and bonds formula draw-in groove 1 and realize
Detachable connection.This bonds formula draw-in groove 1 can embrace landing beam roller bearing 71 and diagonal brace roller bearing 7, it is to avoid overhead welding, it is achieved install
Quickly purpose, it is only necessary to landing beam roller bearing 71 and diagonal brace roller bearing 7 are pushed and can complete in bonding formula draw-in groove accordingly to install.
Further, the inwall of described gap 1-4 is smooth arc line shaped.
Seeing Fig. 4, further, described gap 1-4 is narrow in the outer edge of plate 1-1, wide at members inside
Splayed；Rib 1-5 is formed respectively between the outer wall of the inwall of described gap 1-4 and the plate 1-1 of sides adjacent.This example China and foreign countries
The splayed gap 1-4 of narrow inner width allows for facilitating landing beam roller bearing 71 or the embedding of diagonal brace roller bearing 7 and taking-up, gap simultaneously
Inwall uses smooth arc line shaped to be also based on this consideration.Gap 1-4 herein to a certain extent, to the portion in the inner of installation
Part serves the effect of guiding.
Described Telescopic spring pin 1-6 includes the end that one end of a sleeve 1-61 is fixed on the partition portion of plate 1-1
On head, setting one end of nested pin 1-63 again after spring 1-62 in sleeve 1-61, the other end of pin 1-63 runs through sleeve 1-61
Other end constituted.During embedding, can be compressed during due to pin 1-63 stress, therefore can be made landing beam roller bearing 71 and diagonal brace
Roller bearing 7 is conveniently embedded and bonds in formula draw-in groove 1, and is further ensured that landing beam roller bearing 71 and diagonal brace roller bearing 7 are bonded formula draw-in groove 1
Embrace tightly；On the other hand, as long as compression Telescopic spring pin 1-6, landing beam roller bearing 71 and diagonal brace roller bearing 7 just can be easily
Take out in bonding formula draw-in groove 1.
The free end of further described pin 1-63 is set to inclined-plane, facilitates landing beam roller bearing 71 and diagonal brace roller bearing 7
Embed.
Further, it is positioned on the pin 2-1 inside bolt type steady pin 2-4 and is also arranged with removable insole pieces 2-3.
Further, the outline of described plate 1-1 is totally square.
All parts in this utility model can be respectively adopted steel part.Between landing beam and ladder beam, use pin joint, can rise
Effect to foldable and deformable；And landing beam 4 and diagonal brace 5 pin joint are integrated, free to rotate.
Practical operation can be assembled as follows:
1. landing beam 4, ladder beam 6 are first pre-assembled to folding stair part with diagonal brace 5 on ground；
2., after column 8 makes, can weld bonding formula draw-in groove 1 on it in advance；
3. crane is by folding stair part integral hoisting to every layer setting height(from bottom), now can will be welded on one with diagonal brace 5
The diagonal brace roller bearing 7 risen pushes and bonds in formula draw-in groove 1 accordingly, the landing beam roller bearing 71 that then will weld together with landing beam 4
Push and bond in formula draw-in groove 1 accordingly, just complete the installation of one layer of platform, analogize can progressively install with secondary, until whole stair
Install, the most time saving and energy saving.
