The template inserted pin has the advantages of being ingenious in concept, reasonable in design, reliable in splicing and fixing and convenient to operate, the inserted pin body and the safety pin body are respectively provided with the force discharging face, in an initial pin dropping operation process, with the help of tools such as hammers, the pin foot portion and the inserted pin portion are beat, once the pin foot portion and the inserted pin portion slide to the force discharging faces, the action of shear force will be immediately discharged, therefore, the safety pin body and the inserted pin body can be conveniently taken out, and template dismantling work is achieved.
Description
Technical field:
The utility model belongs to the realm of building construction, and is particularly a kind of in order to lock the template latch of two adjacent template steel frameworks.
Background technology:
Existing steel framework template extensively applies to building, on outer body of wall and the shear wall cast-in-place construction, has characteristics easy for installation, that can be repeatedly used, significantly reduces the waste of timber.The steel framework die shape is rectangular configuration, and build process generally is spliced by plural piece, needs to adopt fastener to be fixed between the adjacent steel frame template.Fastener roughly is divided into outer fastener and interior fastener two classes, and outer fastener is by fastening the steel framework at the adjacent forms back side, reaches the effect of splicing fixed form, and this fastener has only simple function; Interior fastener namely is the steel framework that passes adjacent forms by latch etc., reaches the effect of pinning adjacent forms, has good reliability, and can pin the machine leader to tie wall body two facade templates simultaneously, and dual-use material also makes constructing operation become simple.Interior fastener body is latch, pass in the steel framework preformed hole of adjacent forms, produce bigger shearing force when building shear wall, cause latch stuck in the steel framework preformed hole, be difficult to deviate from, make troubles for the dismounting template, how a kind of latch of being convenient to dismantle template is provided, namely become the object of the utility model research.
Summary of the invention:
The purpose of this utility model is to design on a kind of latch by the steel sheet sheet metal forming and the safety plug to be equipped with the template latch that unloads the power face.
Technical solutions of the utility model are achieved in that a kind of template latch, comprise latch and safety plug, it is characterized in that latch slabbing structure, have a nail head and plug pin portion, the plug pin portion surface is provided with a hole slot for the safety plug insertion, and the one side has the power of unloading face; Safety plug slabbing structure has pin head and a pin foot, and pin foot has the power of unloading face, and sells foot and can insert in the described hole slot, avoids latch to deviate under vibration environment or external force effect.
Described latch and safety plug are the steel disc of the identical and uniform thickness of outline.
All offer hole slot on described latch and the safety plug, both have identical structure.Both are used interchangeably, and offer convenience to constructing operation.
The pin foot of the plug pin portion of described latch and safety plug is class ox horn structure, the arc angle that has a rectangular section and go out toward a lateral deviation, and the big cambered surface of this arc angle is for unloading the power face.
The pin foot of the plug pin portion of described latch and safety plug all has a rectangular section and a wedge-shaped segment, and the inclined-plane of wedge-shaped segment is for unloading the power face.
Above-mentioned wedge-shaped segment is one-sided ramp structure, and this inclined-plane is for unloading the power face.
The long axis direction of described hole slot is consistent with the direction of unloading the power face.
The utlity model has be skillfully constructed, rational in infrastructure, the fixing characteristics reliable, easy and simple to handle of splicing; Latch and safety plug all have the power face that unloads, during initial out of stock operation, and can be by instruments such as hammers, beat pin foot and plug pin portion, unload power face place in case slide to, can unload the effect of shearing force at once, make safety plug and latch conveniently to take out, realize the operation of dismounting template.

The specific embodiment:
See figures.1.and.2, the template latch comprises latch 1 and safety plug 2, and latch 1 slabbing structure has a nail head 11 and plug pin portion 12, and plug pin portion 12 surfaces are provided with a hole slot 13 for the safety plug insertion, and the one side has the power of unloading face 14; 12 one-tenth class ox horns of the plug pin portion of latch 1 structure, the arc angle 122 that has a rectangular section 121 and go out toward a lateral deviation, the big cambered surface of this arc angle 122 is for unloading power face 14.Rectangular section 121 mainly plays stressed effect, and its length is slightly larger than the thickness of two template steel frameworks, makes adjacent forms that reliable location be arranged.
And described safety plug 2 has two kinds of structures, the one, and identical with latch 1 structure, be used interchangeably, bring very big facility to construction; The 2nd, special-purpose safety plug 2 is not namely offered hole slot on its surface yet, and dotted line is represented the position of this hole slot among the figure.
Again, the long axis direction of described hole slot 13 is consistent with the direction of unloading power face 14.In addition, on latch 1 and safety plug 2, also can offer eyelet 15, available iron silk or rope are tied both, perhaps tie up on the steel framework again, form one-to-one relationship, when building template, conveniently take.
With reference to Fig. 3 and Fig. 4, latch 1 is identical with safety plug 2 structures, and the plug pin portion 12 of latch 1 has a rectangular section and a wedge-shaped segment 123, and this wedge-shaped segment 123 is one-sided ramp structure, and this inclined-plane can play the effect identical with last example for unloading power face 14.
With reference to Fig. 5, the application legend when actual template is spliced for latch 1 and safety plug 2, during concatenation, earlier the plug pin portion 12 of latch 1 is inserted in the preformed hole of adjacent steel framework 3 alignment, pass two facade templates simultaneously to the preformed hole of the machine leader 4 that draws, hole slot 13 on its plug pin portion 12 is exposed to outside the opposite side steel framework, inserts safety plug 2 again, reliably pins adjacent forms; After the cast molding, need the dismounting template, this moment, the template that is stitched together was subjected to being parallel and perpendicular to the shearing force effect of the both direction of template face, during dismounting safety plug 2, need overcome the power that is parallel to the template face, the pin portion that utilizes hammer up to knock safety plug 2 until unloading power face place, can take out safety plug; And latch 1 is subjected to the shearing force effect perpendicular to the template face, also needs to knock plug pin portion with hammer, moves it to unloading power face place, can conveniently take out latch.Overcome the defective till traditional latch needs whole to pound out steel framework, make the dismounting template become simply, and can protect the preformed hole structure on the steel framework.
