Abstract
The invention relates to the field of a construction fastener, and particularly relates to a reinforcing fastener of an anti-collapse bracket. The reinforcing fastener comprises a support sleeve which is sleeved on a vertical steel pipe in a sliding manner, wherein the support sleeve comprises a sliding sleeve section and a switch section; the sliding sleeve section is in sliding fit with the steel pipe; the switch section is formed by protruding outwards from the wall of the sliding sleeve section; a support structure for supporting a crossed fastener is arranged at the top of the support sleeve; the reinforcing fastener also comprises a tensioning block which is wedged into the switch section to lock the support sleeve on the corresponding steel pipe; the reinforcing fastener can be sleeved on the vertical steel pipe of a scaffold in use; then the reinforcing fastener is arranged below the crossed fastener in a sliding manner; and finally the reinforcing fastener resists against between the support sleeve and corresponding steel pipe by knocking at the tensioning block, so as to fix the support sleeve. Thus, the reinforcing fastener can play a role of supporting the crossed fastener; the crossed fastener can be effectively prevented from sliding downwards; and the problem of collapse of the existing scaffold caused by poor bonding strength of the crossed fastener and the steel pipe is also solved.
Description
Technical field
The present invention relates to building buckle field, particularly relate to a kind of anti-reinforcement fastener that falls down.
Background technology
Scaffold is one of the most common device in building site, and it is that the rapid construction of building site brings huge convenience.But what require construction safety along with building field improves constantly, it is obviously inadequate that scaffold only can accelerate speed of application, and except accelerating except speed of application, the safety problem of scaffold is also more and more valued by the people.
What current scaffold was maximum is that the form adopting steel pipe to be combined with common cross buckle is built, at most small-sized construction site, possesses fabulous security performance, but, once run into some large work items, the supporting capacity of scaffold and security performance still need to be considered, such as in bridge construction, require that scaffold possesses extremely strong supporting capacity, if this kind of occasion still only adopts common scaffold, then well must ensure construction safety, easily occur the accident of falling down.And according to experience in the past, cause the reason of falling down primarily of two, one is the insufficient strength of cross buckle; Two is that the bond strength of cross buckle and steel pipe is inadequate, and cross buckle glides relative to corresponding steel pipe under heavy condition.The insufficient strength of cross buckle itself still solves by changing the means such as material, by contrast, the problem of the poor bonding strength between cross buckle and steel pipe then seems that some is thorny, if but want the risk reducing construction to greatest extent, then necessarily there is the adhesion that a kind of component can compensate or strengthen between cross buckle and steel pipe.
Summary of the invention
The object of the present invention is to provide a kind of anti-reinforcement fastener that falls down, to solve the problem of falling down that existing scaffold causes due to the poor bonding strength of its cross buckle and steel pipe.
In order to solve the problem, anti-falling down of the present invention strengthens fastener by the following technical solutions: the anti-reinforcement fastener that falls down, comprise the support set for being slidably sleeved on vertical steel pipe, support set comprises sliding sleeve portion for being slidably matched with steel pipe and by the outwardly switch portion formed of the jacket wall in sliding sleeve portion, and the top of support set has the braced structures for supporting cross buckle, this reinforcement fastener also comprises for wedging in switch portion support set to be locked in the expanding block on corresponding steel pipe.
The switch portion of support set is provided with spacing hole, and expanding block is provided with the lever corresponding with spacing hole, and this lever is through the lateral surface protruding from switch portion after spacing hole.
The U-shaped profile of described switch portion, the cross section in sliding sleeve portion is c-shaped, and switch portion and sliding sleeve portion are arranged mouth to mouth, and described spacing hole is located at at the end of the U-shaped that switch portion is formed.
The side towards sliding sleeve portion of described expanding block has the cambered surface with the outline adaptation of corresponding steel pipe.
Described expanding block is provided with the scale being used to indicate its wedging degree of depth.
Described scale is located on the side elevation of expanding block.
Described expanding block is voussoir.
The groove bottom of the groove that the switch portion of support set surrounds is the inclined-plane tilting to draw close to sliding sleeve portion gradually from bottom to top.
Described expanding block to hold out against between switch portion and corresponding steel pipe and is locked by support set when up, and when going upward to extreme position, the upper end of expanding block is still positioned under the braced structures of support set.
Because the anti-support set of strengthening fastener of falling down of the present invention comprises sliding sleeve portion for being slidably matched with steel pipe and by the outwardly switch portion formed of the jacket wall in sliding sleeve portion, and the top of support set has the braced structures for supporting cross buckle, this reinforcement fastener also comprises for being wedged in switch portion support set to be locked in the expanding block on corresponding steel pipe simultaneously, therefore, can this reinforcement fastener be enclosed within the vertical steel pipe of scaffold in use, then make it by sliding the below place being positioned at cross buckle, make it hold out against support set can be fixed between support set and corresponding steel pipe finally by knocking expanding block, thus this reinforcement fastener can be made to play the effect supporting cross buckle, efficiently avoid the downslide of cross buckle, solve existing scaffold due to the poor bonding strength of its cross buckle and steel pipe and the problem of falling down caused.
Further, spacing hole can play position-limiting action to expanding block on the one hand, prevents it from losing, and also makes the lever of expanding block expose on the other hand, thus lever can be made as the force part of expanding block, by knocking lever to realize when locking or unblock support set; The cross section of switch portion is set to U-shaped and can increases bonded area between expanding block and switch portion, increase adhesion therebetween; Described cambered surface can increase the contact area of expanding block and steel pipe, increases the adhesion of expanding block and steel pipe further; Described scale can indicate the wedging degree of depth of expanding block, makes operator obtain the information whether held out against with this; Side elevation scale being located at expanding block can have handled easily, and person observes, and the structure adopting voussoir can simplify switch portion as expanding block is easy to process; Reinforcement fastener of the present invention makes the upper end of expanding block still submerge when expanding block goes upward to extreme position braced structures, expanding block can be avoided like this to contact with corresponding cross buckle, avoid it surprisingly to loosen.
