Abstract
The invention discloses an improved buckling-piece structure for a concrete formwork, comprising a buckling piece, a locking piece and a spring, wherein a clamping pin is arranged at one end of the buckling piece, the end part of the clamping pin is inwards recessed to form a clamping port, and the clamping port is adaptive to the concrete formwork by virtue of a fixing tube. The buckling-piece structure further comprises a sleeve handle, wherein the sleeve handle comprises a grip and a sleeve barrel which are vertically connected; a sleeve tube is arranged on the other end part of the buckling piece; the sleeve tube is arranged along the depth direction of the clamping port; the sleeve tube is sleeved with the sleeve barrel to form a spring cavity; the spring is arranged in the spring cavity, and the both ends of the spring are jacked against the inner cavity wall of the spring cavity; and a locking pin is arranged at one end of the locking piece, and the other end of the locking piece penetrates through the spring and then is connected together with the sleeve handle. In the case that the improved buckling-piece structure disclosed by the invention is used for jointing the formwork, the fixing tube is clamped via the clamping port so that the clamping pin is clamped in a groove on the formwork, the handle is pressed downwards to press the locking pin in another groove on the surface of the formwork, the handle is rotated to clamp the locking pin in the groove, and after the handle is released, the spring bounces to fasten the fixing tube with the formwork together. The spring is not easily corroded by concrete and muddy water, and is capable of normally playing a role because of being arranged in the spring cavity, thus prolonging the service life and eliminating potential safety hazards.
Description
Technical field
The present invention relates to a kind of syndeton of concrete blinding, particularly relate to a kind of improvement concrete blinding fastener structures.
Background technology
A large amount of templates of using in the process of precast concrete, because the concrete blinding that difform building is used is different, therefore most template can not be reused and cause significant wastage; Adopted standardized modular unit, modular unit is reusable and can be spliced into the concrete blinding of various shapes for this reason.But existing modular unit splices when construction a piece, and is fixed with complicated securing member, inefficiency and operation inconvenience.
In order to address the above problem, the applicant has applied for " a kind of ready-package concrete blinding fastener device ", it comprises the fastener being installed in the stationary pipes that fixing splicing concrete blinding uses, and is located in and on this fastener, modular unit is fastened on to the latch fitting in stationary pipes.Fastener is directly connected in the stationary pipes that fixing splicing concrete blinding uses, and latch fitting is fixed on concrete blinding in stationary pipes through after fastener.
But, one end of above-mentioned fastener is fastened in stationary pipes, the other end of fastener is fastened on concrete blinding by latch fitting, due to fastener two ends respectively with the corresponding formation of stationary pipes and concrete blinding assembly relation, so, in order further to improve the efficiency of loading and unloading of concrete blinding, be necessary to improve the structure of latch fitting.
In order to address the above problem, the applicant has applied for " a kind of press fastening type loads and unloads concrete blinding tube clamps device soon ", it comprises fastener, latch fitting and adjusting screw(rod) or adjusting nut, one end indent of fastener forms card division, this card division has the bayonet socket being interlocked by stationary pipes with concrete blinding, latch fitting is supported with rotation by spring and is loosened the other end that the mode of supporting stationary pipes is located in this fastener, and this latch fitting is along the depth direction setting of above-mentioned bayonet socket; Adjusting screw(rod) or adjusting nut are arranged on the outer surface of above-mentioned fastener, and this adjusting screw(rod) is along the depth direction setting of the bayonet socket of described fastener.
But, because above-mentioned spring housing is outside latch fitting, spring can get rusty by burn under the effect of concrete, muddy water, even produce bonding phenomenon, latch fitting spring can not be played a role, and then causes latch fitting can not be pressed in the lip-deep groove of concrete blinding, even if can be pressed in above-mentioned groove, because spring can not normally rebound, latch fitting can not tightly be snapped together stationary pipes and concrete blinding.The polylith concrete blinding being connected together by tube clamps device, stationary pipes so just exists potential safety hazard.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of improvement concrete blinding fastener structures that can prevent spring rust corrosion.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of improvement concrete blinding fastener structures, comprise fastener, latch fitting and spring, one end of fastener is provided with bayonet lock and this end indent forms bayonet socket, bayonet socket and concrete blinding are suitable by stationary pipes, also comprise cover handle, cover is comprising handle and the sleeve being vertically connected on together, the other end of described fastener is provided with sleeve pipe, sleeve pipe is along the depth direction setting of described bayonet socket, sleeve pipe and jacket casing are connected together and form a spring cavity, described spring is arranged in this spring cavity, and two free ends of spring are supported respectively on the internal chamber wall of spring cavity; One end of described latch fitting is provided with lock pin, and the other end of described latch fitting is through linking together with cover handle after spring.
The joining place of described fastener and described bayonet lock is formed with reducing diameter part, and the outer wall that described fastener points to described bayonet lock is provided with reinforcement.
The inwall of described sleeve pipe and described sleeve protrudes respectively formation positioning step, and two described free ends of described spring respectively correspondence are supported on positioning step.
Described jacket casing is outside described sleeve pipe.
Described latch fitting links together by bearing pin and described cover handle.
Adopt after said structure, a modification of the present invention concrete blinding has following beneficial effect with fastener structures: during splicing concrete blinding, first bayonet socket is blocked to stationary pipes and bayonet lock is sticked in the lip-deep groove of concrete blinding, then press down the lock pin that handle makes latch fitting end and compress into lip-deep another groove of concrete blinding, and rotate handle lock pin is stuck in above-mentioned groove, unclamp the bounce-back of handle rear spring, thereby the stationary pipes in bayonet socket and concrete blinding are tightly fixed together.Because spring is arranged in sleeve pipe and the formed spring cavity of sleeve, be difficult for being corroded by concrete, muddy water, spring can normally play a role, thereby has extended the life-span of fastener structures, has eliminated potential safety hazard.
