Specific embodiment
In order to which the purpose of this utility model and advantage is more clearly understood, with reference to embodiments to the utility model into
Row illustrates.It should be appreciated that following text is only used to one or more of specific embodiments of description the utility model,
Considered critical is not carried out to the protection scope that the utility model is specifically requested.
The technical solution that the utility model is taken is as shown in Figures 1 to 3, a kind of reusable exterior wall steel pipe scaffold company
Wall part device, including scaffold 1, drawknot point structure 2 and frame beam 3, the scaffold 1 include horizontally disposed horizontal even wall steel
Pipe 12 and the scaffold internal riser 13 arranged vertically, the horizontal even wall steel pipe 12 pass through fastener 11 and the scaffold internal riser
13 connect, and the drawknot point structure 2 includes T-bolt 24, connects sleeve 23, shell 22 and round steel 21, the T-bolt 24
Screw rod end is connected by connecting sleeve 23 with round steel 21, is also arranged with shell 22 outside the connection sleeve 23；The drawknot node
The T-bolt end of structure 2 is preset in the frame beam 3, the end face and the side of the described one end of shell 22 far from T-bolt
The side flush of grid beam 3 is arranged；The horizontal even wall steel pipe 12 is fixed on the round steel 21 by welding manner；In shell
It is inside inserted in connector sleeve cylinder, T-bolt is screwed into connection sleeve and is embedded in frame beam sides, and one end of round steel is screwed into company by silking
In female connector cylinder, the other end weld horizontal of round steel connects wall steel pipe, level even wall steel pipe by fastener and scaffold internal riser into
The reliable drawknot of row, ultimately forms connector drawknot node device.
Specifically, shell 22 is truncated cone-shaped hollow sleeve, and the relatively large one end of truncated cone-shaped hollow sleeve diameter is close to circle
Steel 21 arranges that the relatively small one end of truncated cone-shaped hollow sleeve diameter is arranged close to T-bolt 24, and truncated cone-shaped hollow sleeve is straight
The end face of the relatively large one end of diameter and the Side shuttering flush arrangement of frame beam 3；Shell is arranged to truncated cone-shaped hollow sleeve, when
Connection sleeve be embedded in frame beam (concrete) it is interior when, small horn-like in the big the inside of collar extension is presented in shell, can pass through hexagonal set
Barrel spanner back-outs shell together with connection sleeve out of frame beam.
As shown in Figure 2 and Figure 3, connection sleeve 23 is hexagonal prisms sleeve, is provided with internal screw thread and positive stop key in hexagonal prisms sleeve
231, the middle position of hexagonal prisms sleeve lining is arranged in the positive stop key 231；It is metal material that sleeve is connected in the present embodiment,
Long 30cm sets diameter inside as 12mm harness cord, positive stop key is additionally provided among hexagonal prisms sleeve, and positive stop key can control hexagonal prisms set
Cylinder both ends are screwed into the half that silking length reaches hexagonal prisms length sleeve respectively, it is ensured that both ends screw rod is screwed into effective length of silking
Degree.
In addition T-bolt is bolt that diameter is 12mm in the present embodiment, T-bolt be embedded in frame beam can increase with
The bond stress of concrete improves the bolt withdrawal resistance of T-bolt；Round steel uses 12 round steel of φ, makees resistance to plucking carrying to 12 round steel of φ
Power detection, as a result 18.1kN is much larger than 8kN, meets " construction fastener type steel pipe scaffold technical specification of security " JGJ130-
It is required in 2011, it is sufficient to illustrate to connect sleeve connection 12 round steel of φ and to be embedded in T-bolt in concrete safe and reliable.
When it is implemented, the interior bone of shell 22 is the regular hexagon being used cooperatively with hexagonal prisms sleeve, it is convenient for six ribs
Column sleeve cylinder is inserted into the through-hole of shell, makes two kinds of close structure fittings.
More specifically scheme is that the positive stop key 231 is retention bead, week of the retention bead along hexagonal prisms sleeve
It is arranged to uniform intervals, and retention bead 231 is at least provided with two.
The specific installation steps of the reusable exterior wall steel pipe scaffold wall-connecting piece device of the utility model are as follows:
Step 1 will connect sleeve 23 first and be inserted into the shell 22 of plastics (or other materials) in hexagonal through-hole, make two kinds
Material is closely engaged and is integrated, and then diameter 12mm silking one end of T-bolt 24 is screwed to connect in sleeve 23 and reaches positive stop key
(the relatively small one end of housing diameter is screwed into outside 231；
Step 2, by scaffold special construction plan determine drawknot node position, place T-bolt 24 and connection sleeve
23 with shell 22, make T-bolt in inside, the relatively large one end end face of housing diameter be placed on the outside of frame beam or shear wall with
Side shuttering flush, casting concrete are paid attention to when pouring to built-in fitting drawknot node finished product protection；
After side template is removed at step 3, drawknot node, 12 round steel of φ is screwed into the connection length of sleeve 1/2 with one end of silking
Degree reaches at positive stop key and (is screwed into the relatively large one end of housing diameter), and the other end of 12 round steel of φ passes through welding manner and level
Even one end of wall steel pipe connects, and even wall steel pipe is carried out level by the scaffold internal riser near fastener and external scaffolding host node
Reliable drawknot；
When step 4, exterior wall scaffold are removed, first by 12 round steel of φ and the wall-connecting piece that wall steel pipe is welding as one horizontal even from even
Back-out in female connector cylinder, then will connect sleeve with hexagon socket wrench and shell is back-outed from concrete, recycling keeping is repeatable
It uses, only T-bolt is stayed in frame beam and can not be recycled and reused；There are one in this side for frame beam or shear wall at this time
A very little hole, slightly fills and leads up processing, will not cause to leak.
In short, reusable exterior wall steel pipe scaffold wall-connecting piece device provided by the utility model, directly by T-type spiral shell
Bolt is screwed into connection sleeve one end and is embedded at the specified tie point of frame beam or shear wall side together with round estrade plastic shell；It tears open
Except when will connect sleeve and plastic shell with hexagon socket wrench and back-out from concrete reusable, only T-bolt stays in
Not reproducible recycling in concrete；Design not only saves fastener at drawknot node and leases used in usage charges and gas cutting in this way
Oxygen and acetylene take, and reduce the waste of steel pipe, moreover it is possible to reach that structure is simple, safe and reliable, economize on resources the purpose that reduces the cost；
Sleeve and truncated cone-shaped hollow sleeve are connected after the taking-up of Vierendeel girder shear wall side, side is slightly filled out there are a very little hole
Flat processing has effectively prevented outer foundation hand hole leakage.
The embodiments of the present invention is explained in detail above in conjunction with attached drawing, but the utility model is not limited to
Above embodiment, for those skilled in the art, in knowing the utility model after contents,
Under the premise of not departing from the utility model principle, several same transformation and substitution can also be made to it, these same transformation and
Substitution also should be regarded as belonging to the protection scope of the utility model.
