Abstract
The utility model relates to building template accessories, more particularly to the readily removable bolt type pin of L shape, including pin body and clamp nut, the pin body front is equipped with threaded portion, the clamp nut screws on the threaded portion, and the pin body rear portion is equipped with the bending head of upward bending, and the rear side outer cylinder in the middle part of the pin body is equipped with undercut portion, the cutting face in the undercut portion is vertical plane, and the downside in the middle part of the pin body is vertically welded with flap shutter.The utility model in pin body by being arranged undercut portion, so that L shape pin rotation need to only can be realized to the disengaging between pin and beam side bottom, reduces disassembly difficulty, construction efficiency improves.
Description
Technical field
The utility model relates to building template accessories, and in particular to the readily removable bolt type pin of L shape.
Background technique
With the development of building iron die system, pin steel framework integrated programme becomes the mainstream of construction.In steel plastic formwork
Construction in, it is various that beam bottom connects quantity with beam side, can be time-consuming if every time all removed connector, therefore to set
Method allows connector to be fixed in beam bottom, and typically now beam side is placed on connector using not allowing connector to land every time,
Side template is just pressed against connector, the problem of causing not Easy disassembling mould, time-consuming due to the effect of pressing force.
Utility model content
The technical problems to be solved in the utility model is in view of the deficiencies of the prior art, to provide L shape readily removable bolt type pin.
The technical problems to be solved in the utility model is achieved through the following technical solutions, and the utility model discloses L
The readily removable bolt type pin of shape, including pin body and clamp nut, the pin body front are equipped with threaded portion, the compression spiral shell
Mother screws on the threaded portion, bending head of the pin body rear portion equipped with upward bending, in the middle part of the pin body
Rear side outer cylinder is equipped with undercut portion, and the cutting face in the undercut portion is vertical plane, and the downside in the middle part of the pin body is perpendicular
To being welded with flap shutter.
Further, the bending angle of the bending head is 90 degree.
Further, the bending inner surface of the bending head is equipped with scarf.
Further, intermediate incline is equipped between the undercut portion and threaded portion of the pin body.
Further, the flap shutter is welded between the bending head of pin body and threaded portion.
Further, the flap shutter selects square plate.
Compared with the prior art, the utility model has the following advantages:
(1) the utility model in pin body by being arranged undercut portion, so that only L shape pin rotation need to can be realized
Disengaging between pin and beam side bottom, reduces disassembly difficulty, and construction efficiency improves；
(2) pin is passed through the direct fixing lock of clamp nut by pin and the integrated design of steel framework by the utility model
It closes on steel framework, it is time saving and energy saving without picking up every time；
(3) the utility model is equipped with flap shutter in pin body and improves beam to realize the accuracy of rotation
The reliability that bottom is connect with beam side.

Specific embodiment
As shown in Figs 1-4, the readily removable bolt type pin of the L shape of the utility model, including pin body 1 and clamp nut 2, institute
1 front of pin body is stated equipped with threaded portion 13, the clamp nut 2 screws on the threaded portion 13, after the pin body 1
Portion is equipped with the bending head 11 of upward bending, and the rear side outer cylinder at 1 middle part of pin body is equipped with undercut portion 14, the undercut
The cutting face in portion 14 is vertical plane, and the downside at 1 middle part of pin body is vertically welded with flap shutter 12.The bending head
11 bending angle is 90 degree, the bending inner surface of the bending head 11 equipped with scarf 111, the pin body 1 it is recessed
It cuts and is equipped with intermediate incline between portion 14 and threaded portion 13, the flap shutter 12 is welded on the bending head 11 and spiral shell of pin body 1
Between line portion 13, the flap shutter 12 selects square plate.In actual use, first with clamp nut 2 by pin body 1
It is fixed on 3 side of beam bottom plate, bending head 11 is gone into position straight up, flap shutter 12 connects with beam bottom limit plate 31 at this time
Touching, beam side plate 4 are placed in pin body 1, so that beam side plate 4 is connected on beam bottom plate 3 using pin body 1, are sold at this time
The cylinder of nail ontology 1 contacts compression with 4 bottom of beam side plate, when needing to remove beam side plate 4, bending head 11 can be rotated 90 degree,
At this moment undercut portion 14 is disengaged with 4 bottom of beam side plate, while bending head 11 is also gone in horizontal plane, can be smoothly by beam side plate 4
It is removed by beam bottom plate 3.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
