Description
Technical field
The utility model belongs to construction technical field of tools, consolidates in particular for the drawknot node of outrigger and structure sheaf
It is fixed.
Background technique
When carrying out erection construction, need to keep defined distance between outrigger and structure sheaf, erection according to
Specification and scheme requirement, step pitch and flooring absolute altitude can have height difference, be not easy that outrigger drawknot node is arranged, while the drawing of roofing frame body out
Node should not be also arranged.
Currently, building field generallys use the steel tube fastener formula outrigger drawknot structure of embedded steel tube in beam as shown in Figure 1
With the drawknot structure of postposition embedded board shown in Fig. 2 and outrigger drawknot.The drawknot structure of Fig. 1 is the side frame outside building floor A
Set a roof beam in place pre-buried one section vertical steel pipe B, sets up auxiliary strut D on construction outrigger C, then drag link E is arranged, passes through cross
Drag link is fixedly connected by fastener with auxiliary strut and embedded steel tube.Using this drawknot structure, in outrigger erection construction process
In, erection needs pre-buried a large amount of steel pipe, and waste of material is big, and assembling and disassembling is cumbersome, and construction finishes outside Demolition Construction
After frame, it is cumbersome to remove pre-buried drawknot steel pipe.The drawknot structure of Fig. 2 is the drag link E that steel plate F is welded with using outer end, will
Steel plate is fixed on the outside of the Vierendeel girder of building floor A with bolt G, and drag link is fixedly connected on building by cruciform fastening for falsework and is applied
On work outrigger C.This drawknot structure will punch blending bolt on Vierendeel girder and steel plate is fixed on Vierendeel girder, construction
Trouble, damages frame beam structure big, and after construction finishes Demolition Construction outrigger, repairing hole is difficult, seriously affect construct into
Degree and increase construction cost.
Summary of the invention
The purpose of this utility model is to solve the problems, such as of the existing technology, provides that a kind of structure is simple, saves material, applies
The band iron drawknot structure of work is simple and construction efficiency is high construction outrigger and structure sheaf.
The purpose of this utility model is achieved through the following technical solutions:
A kind of band iron drawknot structure of construction outrigger and structure sheaf bends l-shaped component, L-type structure by one piece of band iron
The vertical section front end of part is rived along middle line and two sides are formed separately chevron shaped forward and backward, and vertical section part is pre-buried to anchor into building
Vierendeel girder in；It is machined with mounting hole in the horizontal segment outer end of L-type component, cruciform fastening for falsework side bolt is passed through into the installation
Hole, the other side and the cross bar of construction outrigger are connected and fixed.
Band iron specification described in the utility model is long 350mm, width 40mm, thickness 4mm.The L-type component vertical section is chevron shaped
Partial angle is 45 °.
The utility model makes integrated L-type tension member using band iron, and structure is simple, and material consumption is small.L-type is drawn
The vertical section front end of knot part is fabricated to herringbone structure and is embedded in the concrete frame beam of building, and herringbone structure plays very
Good anchoring and lifting effect, i.e., will not loosen, and can ensure that and be bonded with construction outrigger.The horizontal segment of L-type tension member with
Construction outrigger cross bar only needs a cruciform fastening for falsework that can be connected and fixed, and installation and removal all very simples are quick.It has constructed
Cheng Hou cuts off the exposed part of l-shaped member along Vierendeel girder surface, and Vierendeel girder surface will not leave behind hole, be not required to repair,
Saving of work and time.

Specific embodiment
As shown in Figure 3, Figure 4, the band iron drawknot structure of a kind of construction outrigger and structure sheaf, using long 350mm, width
The band iron of 40mm, thickness 4mm, are bent into L-type component, and 1 front end of vertical section of L-type component is rived and forward and backward along middle line
Two sides are formed separately chevron shaped 3 that angle is 45 °, and vertical section part is anchoring section, by its pre-buried Vierendeel girder 7 for anchoring into building
It is interior.The angle of chevron shaped part can also be not equal to 45 °.In the 2 outer end processing mounting holes 4 of horizontal segment of L-type component, for interting
5 side bolt of cruciform fastening for falsework is passed through mounting hole 4, the company of cross bar 8 of the other side and construction outrigger 6 by the bolt of cruciform fastening for falsework
Connect fixation.The utility model institute is that the common cruciform fastening for falsework of scaffold is built in construction using cruciform fastening for falsework 5, can direct city
Purchase.According to practice of construction needs, the specification for making the band iron of L-type component can increase or reduce.
When outrigger is constructed, vertical section part, that is, anchoring section of first L-type component pre-buried in the Vierendeel girder of building, anchorage length
Meet design requirement, after the dismounting of Vierendeel girder side mode, by the horizontal segment of L-type component using the cross of cruciform fastening for falsework and outrigger of constructing
Bar is rigidly connected.
The utility model structure is simple, is easy to make, and consumption material is few, and installation and dismounting are convenient, can simplify working procedure,
Production cost is greatly reduced.In addition, also prevented the drawknot node hole on exterior wall, prevented install perforating when security risk
Deng reducing engineering cost, substantially increase speed of application.
