Description
Technical field
The utility model relates to a kind of jig, relates in particular to a kind of reinforcing bar card.
Background technology
In construction work during concreting, often need to template be through on reinforcing bar and be fixed, or use pull bar that a plurality of templates are fixed together, at present need to be on reinforcing bar or pull bar when fixed form machining screw, or use screwed pull bar, attaching nut is to be fixed again, this has not only increased screw thread processing cost, when the reinforcing bar stretching out outside template or pull bar are longer, need multiple rotary to move the permanent position that screw thread could arrive regulation, thereby can greatly increase workman's the amount of labour.
Chinese invention patent application, application number 200680049122.3, a kind of reinforcing-bar engagement device is disclosed, it comprises possessing have the main component of the through hole that reinforcing bar can pass and be embedded into through a plurality of chimeric member between the reinforcing bar of through hole and the inner peripheral surface of this through hole, the inner peripheral surface of through hole is made to the funnel shaped dwindling along axis direction diametric(al), on the inner peripheral surface of chimeric member, be provided with the holding section with above-mentioned reinforcing bar, at least a portion of the outer peripheral face of chimeric member, be provided with the inner peripheral surface of aforementioned body member and carry out the taper seat that face contacts.Adopt above-mentioned reinforcing-bar engagement device when reinforcing bar has pretension, to it, to carry out engaging, but do not apply under the state of tension force when reinforcing bar, or reinforcing bar is while in use occurring axially to change, and can cause chimeric member in through hole, to occur to become flexible, and then cause the not firm of engaging, even lost efficacy.
And for example Chinese utility model patent CN2291464Y discloses a kind of Reinforcing bar clamp, it comprises draw ring, draw ring connects a card, there is one section of conical bore at card center, in conical bore, correspondence is fitted with conical dop, and there is the reinforcing bar jack of band card tooth at dop center, and dop is at least two halves structure along jack, conical bore end has a gland, between gland and dop, spring is housed.This jig in use, when being applied with pulling force to reinforcing bar, jig can have good engaging to reinforcing bar, if but while there is axially change in reinforcing bar, dop is also easily loosening in card, and then cause reinforcing bar to come off, if and select the spring that stiffness factor is larger, can make gland to screw moment of torsion excessive, be not easy to operation.
Utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of reinforcing bar card, and it can carry out engaging in the optional position of reinforcing bar or pull bar, simple to operate, and engaging is firm.
For achieving the above object, this reinforcing bar card comprises inner hollow and has the body of the through hole passing for reinforcing bar, also comprise the fixture block that is arranged on body interior, on body, be connected with to fixture block apply active force so that fixture block is pressed on the retaining mechanism in inner body wall by penetrate intrinsic reinforcing bar by through hole.Adopt this scheme, by arriving after assigned position in reinforcing bar or pull bar insertion body, use retaining mechanism to promote fixture block, thereby reinforcing bar or pull bar are pressed in inner body wall, and retaining mechanism after reinforcing bar or pull bar compression can not become flexible voluntarily, can make the engaging in body of reinforcing bar or pull bar firm.
As to restriction of the present utility model, described retaining mechanism comprise be threadedly connected on described body, fixture block is implemented to the bolt of pushing tow.Adopt the bolt being threaded with body to make simple to operate, and be convenient to body manufacture.
As the restriction to aforesaid way, the axis of described bolt stretches into the angle that body direction becomes along the center line edge of stretching into body direction and described through hole be obtuse angle.This just makes under the pushing tow of bolt, fixture block has to the thrust of reinforcing bar the reinforcing bar of preventing axially movable component occurs, especially the direction of advance when body interior compresses along fixture block is designed to the gradually little infundibulate in space, and fixture block is positioned at its direction of advance one end and is designed to be funnel shaped cavity shape when similar with body, can make the engaging of reinforcing bar reach better effect.
As to restriction of the present utility model, on the contact surface of fixture block and reinforcing bar, be provided with the first engaging groove matching with reinforcing bar external surface, the setting of the first engaging groove can make the profile of fixture block and reinforcing bar or pull bar match, and increase the contact surface of fixture block and reinforcing bar or pull bar, thereby be more conducive to fixture block holding tightly reinforcing bar or pull bar.
As the restriction to aforesaid way, the inner body wall relative with the first engaging groove is provided with the second recessed engaging groove.
As the restriction to aforesaid way, at the first engaging groove and the second engaging groove, at least on one, be provided with screw thread, set up screw thread and can increase the first engaging groove or the enclasping force of the second engaging groove to reinforcing bar or pull bar.
As to improvement of the present utility model, the one end on body with through hole is provided with chevron card, can make purposes of the present utility model more extensive.
In sum, adopt the technical solution of the utility model, can to it, carry out firm engaging in the optional position of reinforcing bar or pull bar, and saved reinforcing bar or pull bar machining screw and repeatedly screwed the trouble of nut, simple to operate, save man-hour, and its one end is designed to chevron card, saved equally the inconvenience that common chevron card need screw nut.
