Abstract
The utility model relates to building support apparatus field, disclose a kind of scaffold butt joint fastener, comprise bowl button, lower bowl button, set bolt, locking nut, set bolt adopts T-slot bolt, by set bolt run through that screw that upper bowl button and lower bowl buckle forms steel pipe fixing, the screw place detained at lower bowl arranges boss, boss caves inward formation circular groove, and T-shaped set bolt just in time can be placed in groove.The utility model uses T-slot bolt to replace traditional bolt, and the setting of the boss with groove structure is buckled by lower bowl, when T-slot bolt is through upper and lower bowl button, groove structure just in time can fix T-slot bolt, the locking nut screwing the T-slot bolt other end is only needed when locking, facilitate operation, also save material.
Description
Technical field
The utility model relates to building supporting field of components, especially a kind of be applied on scaffold to clasp.
Background technology
Building trade is the important component part of Chinese national economy, the support apparatus of building trade experienced by the upgrading of various ways from ancient times to the present, wherein more representational is upgrading from from bamboo support apparatus to steel lining equipment, no matter be bamboo support apparatus or steel lining equipment, fastening devices is all very important, in steel lining equipment in the prior art, scaffold is more typical, its main composition is steel pipe and to clasp, rely on and some steel pipes are fixed by the support apparatus forming architecture enclosing to clasp, Fig. 1 is the structural representation to clasp of prior art, as shown in Figure 1, bowl fastening type conventional is at present rely on set bolt to run through to clasp, steel pipe is fixed by the effect of locking nut by lower two bowl buttons, two ends due to set bolt are all to stretch out, lower bowl button, at this moment need to realize fixing just must use, lower two locking nuts, and must be dependence two spanners when locking, a locking nut is first fixed by a spanner, rotating another locking nut to be fixed with spanner, this fixed form is obviously cumbersome, and require that operator two hand works simultaneously, therefore this fixed form of scaffold needs to improve.
Utility model content
The purpose of this utility model is overcome above-mentioned the deficiencies in the prior art and provide a kind of scaffold butt joint fastener, solve scaffold of the prior art use clasp is fixed time cumbersome, need simultaneously to the problem that two locking nuts operate.
For achieving the above object, the technical solution adopted in the utility model is:
Scaffold butt joint fastener, comprise bowl button, lower bowl button, set bolt, locking nut, is characterized in that: described set bolt adopts T-slot bolt, by set bolt run through that screw that upper bowl button and lower bowl buckle forms steel pipe fixing, arrange boss at the screw place of described lower bowl button, described boss caves inward formation circular groove, and described T-shaped set bolt just in time can be placed in groove.
As preferably, described boss and lower bowl button one-body molded, circular groove is machined by milling machine.
As preferably, described boss is welded on the screw place of described lower bowl button.
As preferably, described locking nut is hex nut, and is provided with pad at locking nut and the contact position of upper bowl button.
The technical program mainly for of the prior art to clasp when being fixed steel pipe, use spanner is needed to be fixed a locking nut, the problem that the practical operation caused operating another locking nut with spanner is cumbersome, the technological means adopted mainly uses T-slot bolt to replace traditional bolt, and reeded boss is set by the screw place detained at lower bowl, when T-slot bolt is through upper, during lower bowl button, one of T-slot bolt corrects and can be fixed in the groove of boss, when needs contacting piece is locked, only need to screw with spanner the locking nut that upper bowl buckles can complete.
The beneficial effects of the utility model: use T-slot bolt to replace traditional bolt, and the setting of the boss with groove structure is buckled by lower bowl, when T-slot bolt is through upper and lower bowl button, groove structure just in time can fix T-slot bolt, the locking nut screwing the T-slot bolt other end is only needed when locking, facilitate operation, also save material.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art;
Fig. 2 sectional drawing of the present utility model;
Fig. 3 is top view of the present utility model;
Fig. 4 is upward view of the present utility model;
Fig. 5 is the structural representation of the utility model T-slot bolt.
In figure: the upper bowl button of 11-, bowl button under 12-, 3-pad, 4-locking nut, 5-steel pipe, 6-boss, 7-set bolt, 8-groove.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model and operating principle is described in a schematic manner.
Shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, scaffold butt joint fastener, comprise bowl button 11, lower bowl button 12, set bolt 7, locking nut 4, described set bolt 7 adopts T-slot bolt, forms fixing steel pipe, arrange boss 6 at the screw place of described lower bowl button 12 by set bolt 7 screw run through on upper bowl button 11 and lower bowl button 12, described boss 6 caves inward formation circular groove 8, and described T-shaped set bolt just in time can be placed in groove 8.
As preferably, described boss 6 and lower bowl are detained 12 one-body molded, and circular groove 8 is machined by milling machine.
As preferably, described boss 6 is welded on the screw place of described lower bowl button 12.
As preferably, described locking nut 4 is hex nut, and is provided with pad 3 at locking nut 4 and the contact position of upper bowl button 11.
In practical operation, when needs are fixed steel pipe 5, first two joint steel pipe adjustment positions are docked, with bowl button 11 and lower bowl button 12, steel pipe 5 is encased, after aligned position, set bolt 7 is inserted, in the screw of lower two bowl buttons, make one of tee T bolt to correct and can be fixed in the groove 8 of boss 6, because one end of tee T bolt has been fixed, only need to be tightened with spanner when locking the locking nut 4 of bolt 7 other end, doing so avoids and act on while set bolt 7 two ends locking nut 4, facilitate operation, also save material simultaneously.
Certainly; as other embodiments of the present embodiment; fixed form for the set bolt other end can adopt various ways; in a word, the simple change structurally or in fixed form made under the enlightenment of above-mentioned detailed description of the invention of those skilled in the art or displacement all belong to protection domain of the present utility model.
