Description
Technical field
The utility model relates to a kind of edge protection of steel pipe, specifically a kind of L applied in steel pipe type edge protection
Shape group welds bolt arrangement.
Background technique
With national market rapid economic development, urbanization progress, land resource is increasingly reduced, city is on the middle and senior level,
Super high-rise building is increasing, and Building Construction security protection also can not be ignored.In construction, to prevent personnel from falling
It falls, it is standing to set edge protection.
Existing edge protection structure is typically all that material is fixed by fastener etc., and material is typically all to be rented
It rents or buys, higher cost.
Utility model content
The purpose of this utility model is to provide a kind of L shape groups applied in steel pipe type edge protection to weld bolt arrangement,
To solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions:
It is a kind of apply in steel pipe type edge protection L shape group weldering bolt arrangement, including be pierced by shearing wall column to draw spiral shell
Bolt, chevron card and nut, the split bolt are L-shaped structure, and shearing wall column is corresponding to the upper and lower of the exposed parts of split bolt
Two sides are respectively equipped with steel pipe, and chevron cutting ferrule is located at the head end of split bolt, and nut is fixed on the head end of split bolt and locking, makes
It obtains chevron card to compress steel pipe, forms steel pipe edge protection.
As a further solution of the present invention: the contact surface of the chevron card and steel pipe is and steel tube surface mutual
The curved surface matched.
The split bolt includes steel bar end and screw rod as a further solution of the present invention, and screw rod welding is solid
It is scheduled on the head end of L shape steel bar end.
The split bolt is arranged in the part in shearing wall column as a further solution of the present invention,
PVC casing.
Compared with prior art, the utility model has the beneficial effects that after the penstock installation of this edge protection externally
Stress is directly applied to shearing wall column, and stress intensity is limited with the bending strength of steel pipe, greatly exceeds and require in associated safety
Dynamics, be the several times that it requires dynamics, do not limited by installation form again, improve and improve for traditional edge protection
Optimal selection form, have the advantages that at low cost, reusable and economical environment-protective, have shear wall, column etc. cast-in-place on both sides
It can be widely used when the case where reinforced concrete member.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of L shape group weldering bolt arrangement applied in steel pipe type edge protection.
In figure: 1- shears wall column, 2- chevron card, 3- nut, 4- steel pipe, 5- split bolt, 6-PVC casing, 501- reinforcing bar
Head, 502- screw rod.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, in the utility model embodiment, a kind of L shape group weldering bolt applied in steel pipe type edge protection
Structure, split bolt 5, chevron card 2 and nut 3 including being pierced by shearing wall column 1, the split bolt 5 are L-shaped structure, shearing
Wall column 1 is respectively equipped with steel pipe 4 in the two sides up and down of the exposed parts of corresponding split bolt 5, and chevron card 2 is set in split bolt 5
Head end, nut 3 is fixed on the head end of split bolt 5 and locking, so that chevron card 2 compresses steel pipe 4, forms steel pipe and faces frontier defense
Shield, since stress external after the penstock installation of this edge protection is directly applied to shearing wall column 1, stress intensity is with steel pipe 4
Bending strength be limited, greatly exceed the dynamics required in associated safety, be the several times that it requires dynamics, do not pacified again
The limitation of dress form improves and improved optimal selection form for traditional edge protection.
The contact surface of the chevron card 2 and steel pipe 4 is the curved surface being mutually matched with 4 surface of steel pipe.
The split bolt 5 includes steel bar end 501 and screw rod 502, and screw rod 502 is weldingly fixed on the head of L shape steel bar end 501
End, when practice of construction, (screw thread and round steel are ok the bar dowel head that can be directly discarded using construction site, as long as length reaches
Just to 200MM or so) and discarded screw head through walls (exterior wall water-proof bolt pounds the split bolt head to get off), butt welding is carried out
Connect, form split bolt 5, with this split bolt 5 pass through the split bolt hole on shearing wall column 1 to the steel pipe 4 of edge protection into
Row is effectively fixed.
The split bolt 5 is arranged with PVC casing 6 in the part in shearing wall column 1, i.e., opens on shearing wall column 1
If split bolt hole in PVC casing 6 is installed, convenient for the placement of split bolt 5.
Having the advantage that for the utility model is as follows:
Secure context: it is more firm than traditional part after fixed, subsequent construction is influenced small, it is not easy to it is removed, destroys, it can be long-term
It keeps；
Protect quality: bearing capacity is big, and more than the dynamics several times of safety code requirements, edge protection effect is very good；
Cost effectiveness: can be all using the waste of construction site, material cost is negligible, only consumes a small amount of artificial
Cost is not easy to be removed, destroy compared to traditional approach, saves the cost of labor for repeatedly restoring protection, can be used in turn, further
Cost is reduced, is increased economic efficiency；
Saving metal material and energy: live waste material (discarded steel bar end, discarded sealing up screw head) is made full use of, traditional approach saving is compared
Fastener etc. leases material, reaches section material effect, while the steel material that this part is discarded is turned waste into wealth, and does not need to melt down smelting again
Refining, reaches effects of energy conservation and environmental protection, finally realizes saving metal material and energy.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in
All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting
Related claim.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
