Description

Template assembly connecting fastener

Technical field

The invention belongs to construction formwork interface unit field, relate to a kind of template assembly connecting fastener.

Background technology

In the prior art, construction formwork, when steel template or wooden template connect use in assembly unit, adopt common bolt, nut perforation formula assembly unit ways of connecting mostly, this traditional interface unit has tangible deficiency: speed of application is slow, and the template assembly quality is difficult for guaranteeing, easily is damaged at the construction field (site), and be easy to after being shaken become flexible voluntarily, have a strong impact on the concrete casting quality sometimes; Also have many enterprises to adopt as: disclosed assembly unit cover card among the Chinese patent ZL992058503, its structure is: have the double hook pin on the main component, and puller bolt relative with the double hook pin and the band saddle shaped plate put arranged, during use, need have supporting diplopore on the Form board frame, the double hook pin hooks in the diplopore, saddle shaped plate rides over the top of two Form board frames, locking puller bolt then gets final product, the great advantage of this kind interface unit is that speed of application is fast, but still have tangible weak point: Form board frame must have the diplopore of standard, also be damaged easily at the construction field (site), be easy to loosening voluntarily after being shaken, strict to double hook pin inside dimension simultaneously, and after repeatedly using, be that the supporting diplopore or the double hook script body of Form board frame all can dimensional errors take place because of wearing and tearing, thereby bring the influence that is difficult to avoid for the template assembly quality, thereby influence the concrete casting quality; For another example: the disclosed anchor clamps scheme of Chinese patent ZL012711071, form by three parts: the wedge of band wedge tooth, a left side half fastener and right half fastener of band tooth bar, during use, the contraposition of left and right two halves fastener is stuck on the frame of template, at this moment, tooth bar on half fastener of a left side passes the groove of right half fastener. the road, then wedge is inserted from vertical hole of conduit and mesh together with horizontal tooth bar, when applying wedging power, because helical teeth function, produce lateral displacement under wedge tooth and the tooth bar engagement, tightly combine mutually thereby drive the two halves fastener; The great advantage of this kind anchor clamps is that speed of application is fast, template assembly is fastening reliable, also need not punching on the frame of template, but has high and other the unsatisfactory parts of cost; The disclosed new-type connector of Chinese patent ZL031374328 for another example, mainly form by special-shaped plate bolt and supporting T-shaped spring wedge, during use, special-shaped plate bolt passes the connecting hole on the assembled formwork frame, the bar hole of T-shaped spring wedge is enclosed within the bolt shoulder and goes up and be stuck on the inside face of bolt head, after the wedging, the wedge body produces certain elastic buckling, and its great advantage is simple in structure, easy construction, wear-resistant and anti-collision, long service life, its weak point are that the elastic buckling of wedge body is prone to fatigue, and artificial wedging dynamics is difficult for holding, during use, the fastening speed of application that still influences of boring a hole is one by one also easily lost etc. simultaneously.

Summary of the invention

The technical problem that solves:

A kind of template assembly connecting fastener is provided, adopts the movable chuck wedge of holding concurrently fastening, and the structure that dop and wedge are integrated is as the template assembly connector, can overcome the deficiencies in the prior art, the dress hole that need not on the Form board frame to fight, simple in structure, easy to use, locking and dismounting speed are fast, easy damaged and losing not, cost is low, long service life, in the fastening process of wedge, template can be located automatically, levelling, and stress was good during template assembly used, fastening reliable, assembly unit quality height.

The technical scheme that adopts:

Template assembly connecting fastener, have dop 1 and wedge 6, it is characterized in that: fixed claw 2 positioning and fixing of dop 1 are on positioning body 4, the movable claw 3 of dop 1 by little axle 5 and positioning body 4 hinges together, wedge 6 is subjected to mechanical axis 7 and movable claw 3 hinges together by what be contained in movable claw 3 afterbodys, has the oblique slideway 8 that is subjected to mechanical axis 7 on the wedge 6; When jig was applied to flat formwork assembly unit flat formwork, positioning body 4 was straight tube-like, had automatic location, double inner plane 9 and the outerplanar 10 stressed and parallel to each other of smoothing; Slideway 8 and outerplanar 10 also are that the baseplane 11 of wedge 6 is the α angle, and α is generally 4～10 °; The pawl head position of fixed claw 2 and movable claw 3 has frame 16 supporting corresponding chucking faces 12 and the double smoothing face 13 in location with template.

Beneficial effect:

Adopt the movable chuck fastening structure of wedge of holding concurrently, and dop and wedge be integrated, the dress hole that need not to fight on simple in structure, easy to use, the Form board frame, and locking and dismounting speed are fast, easy damaged and losing not, cost is low, and long service life is in the wedge 6 fastening processes, template can be located automatically, levelling, stress was good during template assembly used, and fastening reliable, assembly unit quality height can be applicable to the assembly unit of multiple shape template.

The specific embodiment

Further explanation in detail in conjunction with the accompanying drawings;

As shown in Figure 1, when jig was applied to flat formwork assembly unit flat formwork, positioning body 4 was straight tube-like, had automatic location, double inner plane 9 and the outerplanar 10 stressed and parallel to each other of smoothing; Slideway 8 and outerplanar 10 also are that the baseplane 11 of wedge 6 is the α angle, and α is generally 4～10 °.

Shown in Fig. 1～4, it is board-like that fixed claw 2 and movable claw 3 are double fastener, two clamping plate of movable claw 3 are connected to one by mechanical axis 7; The pawl head position of fixed claw 2 and movable claw 3 has frame 16 supporting corresponding chucking faces 12 and the double smoothing face 13 in location with template.

As shown in Figure 5, when jig is applied to the external corner template of flat formwork assembly unit angle mould, positioning body 4 is the crutch shape of being with right-angle side 14, fixed claw 2 positioning and fixing are in the end of right-angle side 14, have automatic location, smoothing inner plane 9 and the outerplanar 10 stressed and parallel to each other of holding concurrently, the inboard of right-angle side 14 have perpendicular to automatic location, the levelling of inner plane 9 hold concurrently stressed in plane 15; Slideway 8 and outerplanar 10 also are that the baseplane 11 of wedge 6 is the α angle, and α is generally 4～10 °.

As shown in Figure 6, movable claw 3 is that double fastener is board-like, its double plate is connected to one by mechanical axis 7, and the pawl head position of movable claw 3 has frame 16 supporting corresponding chucking faces 12 and the double smoothing face 13 in location with template.

The concrete structure size at each parts, position, especially fixed claw 2, movable claw 3 and wedge 6 on the jig must be supporting corresponding with the physical dimension of template corresponding and frame 16 thereof, and be easy to use to guarantee, fastening reliable, template assembly quality height.

Jig of the present utility model is equally applicable to the assembly unit of circular arc template, and template assembly to add epistasis fastening.Press among Fig. 1,5 shown in the arrow, after jig is in place, wedge 6 is applied wedging power, wedge 6 is in slip, being subjected to mechanical axis 7 by oblique slideway 8 drives, is the point of rotation thereby make movable claw 3 with little axle 5, drives its reverse displacement in claw position, its chucking face 12 and the location smoothing face 13 of holding concurrently is stuck on the frame 16 tightly, to wedge 6 oppositely apply power then jig unclamp.
