Description
Technical field
The present invention relates to towering structure technical field of construction, and in particular to a kind of towering structure constructor row ladder is helped
The fixed device of wall and construction method.
Background technique
Currently, towering structure construction be both needed to set up people's row safety climbing ladder for construction worker above and below, traditional handicraft
In, the connection of people's row safety climbing ladder and towering structure and fixed take install embedded part more on towering structure, pass through connection
The mode of rod piece and slugging consolidates ladder, or to drawing, reinforcement welding connecting rod is fixed to be climbed using towering structure template
Ladder has the disadvantage in that in practice of construction
(1) it by the way of pre-buried slugging connecting rod, needs to bury a large amount of embedded parts in construction.It is easily buried in embedded part construction
Enter in concrete, need when demoulding to find and digs out embedded part.Embedded part needs to weld with connecting rod, and when dismounting need to carry out oxyacetylene metal-cutting and cut off, high
Sky carries out oxyacetylene metal-cutting operation inconvenience and there are very big security risks.Embedded part after cutting off connecting rod need to polish and make antirust treatment.
(2) after drilling installation slugging connecting rod by the way of, boring damage concrete surface, and easily with main reinforcement phase
It touches, makes troubles to drilling.Embedded part needs to take out expansion bolt after removing, and carries out bolt hole reparation.Embedded part mode is installed after drilling
Embedded part buried depth is shallow, and wind loading rating is lower, and there are security risks.
One connecting rod of (3) pre-buried point connections needs to increase embedded part point if it is desired to increasing stability, can be to height
It alarms structures concrete surface and causes more repairing faces, do not need the clear-water concrete of later period decoration especially, one can be reduced
The qualification rate of secondary construction.
(4) embedded part for needing to remove, in demolishing process, it is difficult to remove, and is easy to cause concrete at embedded part big break
It is bad, increase repairing face.The old and new's structure is easy to produce shrinkage joint, apparent repairing defect occurs, and perception is poor.
(5) embedded part that do not remove, surface need to polish and make antirust treatment, not only bad for towering structure clear water coagulation
Native appearance also needs later period long term maintenance.
In consideration of it, needing to invent the knot that a kind of construction efficiency is high, adhesive force is strong, the repairing surface of a wound is small and can reuse at present
Structure and construction method.
Summary of the invention

Gu.
Mountable horizontal constructions steel pipe 25 and building buckle 26 between the stationary fixture of two joint outer parts, can be to apply
The equal scaffolds facility of worker's row safety climbing ladder 27 provides sustaining wall connection.
The present invention also proposes a kind of fixed construction method of towering structure constructor row ladder sustaining wall, and this method includes following
Step:
The first step, the installation of built-in fitting suit component.Tapered cup nut 1 and resistance to plucking rod piece are fitted together first, and wrapped up
Good corrugated cover；When installation, according to 27 size of constructor's row safety climbing ladder that standard knot forms, above-mentioned built-in fitting suit component is measured
Installation site, evacuation towering structure inside reinforcing bar, is then installed.Installation method multiplicity: (1) as shown in figure 4, passing through spiral shell
Bolt 1 is directly attached from template 24 and tapered cup nut 1, can be increased sealant between tapered cup nut 1 and template 24, be prevented ash
It starches excessive.When form removal 24, bolt 1 is removed.(2) as shown in figure 5, bolt 2 10 is connect with tapered cup nut 1, so
Another section of screw thread of bolt 2 10 is passed through on the inside of template 24 afterwards, and is secured with nuts.When dismounting, nut is removed, then remove
Template 24 removes bolt two finally by the hole of 2 two sections of screw rod junctions of bolt.The hole that method (2) is reserved in template 24
It is smaller.
Second step, sustaining wall joint outer part, support installation.When form removal 24, connection construction people's row safety climbing ladder is needed
When 27, corresponding above-mentioned first one step process, is that method (1) removes bolt 1 respectively, method (2) removes nut, then form removal
24, finally by the hole of 2 10 two sections of screw rod junctions of bolt, bolt 2 10 is removed, joint outer part is connected by bolt 1
It connects.The screw rod of joint outer part 19 is connect with tapered cup nut 1 first, by being inserted into crooked chisel in the hole of nut casing 20
Carry out the elastic adjusting of screw rod.More than two joint outer parts are installed, stationary fixture is opened, horizontal constructions steel is further installed
Pipe 25 and building buckle 26, then other building steel tubes 25 are subjected to horizontal constructions steel pipe 25 and constructor's row safety climbing ladder 27 etc.
Sustaining wall connection between scaffold facility.
Third step, built-in fitting suit component are removed.When constructor's row safety climbing ladder 27 is removed, support dress is successively removed
It sets, while spanner is removed by using tapered cup nut and removes tapered cup nut 1, in use, bolt 12 is directed at inserting for tapered cup nut 1
Hole 3, the screwed connection of fastening bolt 13 and tapered cup nut 1 further compress spanner 11 and tapered cup nut 1, are formed whole.Peace
Dress pulls pawl 14, makes the four croziers adaptation for pulling 11 outer of pawl 14 and spanner.It combines ratchet spanner 16 with hexagon sleeve head 15
Together, then by hexagon sleeve head 15 it is mounted on the hexagon for pulling pawl 14, is back and forth pulled, pawl is pulled in the drive of ratchet spanner 16
14 single direction rotations counterclockwise can quickly remove tapered cup nut 1.Finally unclamp the screw thread of fastening bolt 13 and tapered cup nut 1
Connection, tapered cup nut 1 is recycled.
Then corrugated cover is removed using corrugated cover removal tool, in use, steel wire 7 is inserted into threaded hole of steel 18.2 first
In, cover wall is torn, boss band 6.1 is formed, then in the boss with holes 18.2 that the end of boss band 6.1 is inserted into the body of rod 18, rotation
Turn lever 17, at this point, boss with holes 18.2 has clamped down on boss band 6.1, the cover wall of corrugated cover 5 caused to tear from cutting 8,
And volume is covered on the body of rod 18, band portals outer.Finally, device to hole carries out cleaning and mortar blocks.
Protection scope of the present invention is not limited to the above embodiments, it is clear that those skilled in the art can be to this hair
It is bright to carry out various changes and deformation without departing from scope and spirit of the present invention.If these changes and deformation belong to power of the present invention
In the range of benefit requirement and its equivalent technologies, then including the intent of the present invention also includes these changes and deforms.
