Abstract
The utility model relates to architectural hardware field, in particular to a kind of U-shaped Superimposed fastener, comprise U-shaped Connection Block and the some laemodipodiform reinforcing ribs fixing with U-shaped Connection Block, fix bottom described laemodipodiform reinforcing rib upper end and U-shaped Connection Block, the bottom of described laemodipodiform reinforcing rib is herringbone or branch shape bifurcated downwardly towards surrounding.U-shaped Superimposed fastener of the present utility model makes its bearing capacity strong by the structure changing laemodipodiform reinforcing rib, is connected firmly, can meets building field high strength grappling requirement.
Description
Technical field
The utility model relates to architectural hardware field, particularly a kind of U-shaped Superimposed fastener for building, can be widely used in building curtain wall, the installation of mining equiment, fastening field.
Background technology
Superimposed fastener installs (burying) component in concealed work in advance, and be the component and fitting settled when structure is poured into a mould, for building overlap joint during superstructure by laying bricks or stones, the installation being beneficial to external works equipment Foundations is fixed.At present, although the Superimposed fastener form that building field adopts is different, varied, be made up of pre-buried cell body Connection Block and the embedded ribs be fixed on Connection Block nothing more than, the Connection Block adopted is C shape, and the embedded ribs adopted is screw-thread steel and H-shaped steel.Extensive application practice shows, this Superimposed fastener structure is simple, and mechanical property is bad, and bearing capacity is little, and when building operations, security performance is not ideal enough.
In recent years, with design level and building the improving constantly of ability, curtain wall decoration, traffic track and highway construction field were had higher requirement to the stability of Superimposed fastener and safety.For this reason, existing Superimposed fastener needs to improve further on stuctures and properties, to meet the security requirement of building operations.
Utility model content
The utility model, for Superimposed fastener structure Problems existing for building of the prior art, provides a kind of bearing capacity strong, is connected firmly, can meets the U-shaped Superimposed fastener of building field high strength grappling requirement.
The purpose of this utility model realizes like this, a kind of U-shaped Superimposed fastener, comprise U-shaped Connection Block and the some laemodipodiform reinforcing ribs fixing with U-shaped Connection Block, fix bottom described laemodipodiform reinforcing rib upper end and U-shaped Connection Block, the bottom of described laemodipodiform reinforcing rib is herringbone or dendriform bifurcated to surrounding.
Structure U-shaped Superimposed fastener beneficial effect of the present utility model is: the U-shaped Connection Block of this U-shaped Superimposed fastener can adopt hot rolling U-shaped steel or the blanking of hot bending shaping U-shaped steel of general certain size specification, and U-shaped Connection Block inner bottom part arranges the through hole for installing laemodipodiform reinforcing rib at a certain distance; Described laemodipodiform reinforcing rib adopts mild steel through hot forging forming, one end of reinforcing rib and Connection Block are riveted at through hole position and are combined, reinforcing rib other end end strikes out herringbone or the dendriform to circumferential bifurcated, during construction, laemodipodiform reinforcing rib bottom U-shaped Superimposed fastener and U-shaped Connection Block are embedded in building substrate (as concrete) in advance, play the effect of connecting building matrix (concrete); Laemodipodiform reinforcing rib end is herringbone or dendriform bifurcated to surrounding, is conducive to improving the anchoring strength between building substrate (concrete) and reinforcing rib, improves the bearing capacity of Superimposed fastener.
For improve further U-shaped Superimposed fastener of the present utility model pre-buried after anchoring strength, the radial dimension from the top down of described joint bamboo shape reinforcing rib increases gradually.
Being fixedly connected with and improving bonding strength, described laemodipodiform reinforcing rib and U-shaped Connection Block riveting for convenience of laemodipodiform reinforcing rib and Connection Block, and rivet reinforcement of weld afterwards.
For improving the anchoring strength of shape Superimposed fastener further, the upper end open edge of described U-shaped Connection Block bends inwards.
Accompanying drawing explanation
Fig. 1 is the front view of U-shaped Superimposed fastener of the present utility model.
Fig. 2 is the left view of U-shaped Superimposed fastener of the present utility model.
Wherein, 1 U-shaped Connection Block; 2 laemodipodiform reinforcing ribs.
Detailed description of the invention
As depicted in figs. 1 and 2, for the novel U-shaped Superimposed fastener of this practicality, comprise U-shaped Connection Block 1 and the some laemodipodiform reinforcing ribs 2 fixing with Connection Block 1, fix bottom laemodipodiform reinforcing rib 2 upper end and U-shaped Connection Block 1, the bottom of laemodipodiform reinforcing rib 2 is herringbone or dendriform bifurcated to surrounding, and the present embodiment is illustrated in figure 2 herringbone bifurcation structure; For improve further U-shaped Superimposed fastener pre-buried after anchoring strength, the radial dimension from the top down of joint bamboo shape reinforcing rib 2 increases gradually; Being fixedly connected with and improving bonding strength for convenience of laemodipodiform reinforcing rib 2 and U-shaped Connection Block 1, laemodipodiform reinforcing rib 2 and U-shaped Connection Block 1 riveting, and riveted joint reinforcement of weld afterwards; For improving the anchoring strength of shape Superimposed fastener further, the upper end open edge of U-shaped Connection Block 1 bends inwards, as shown in Figure 2.
When U-shaped Superimposed fastener of the present utility model makes, U-shaped Connection Block 1 can adopt hot rolling U-shaped steel or the blanking of hot bending shaping U-shaped steel of general certain size specification, and U-shaped Connection Block 1 inner bottom part arranges the through hole for installing laemodipodiform reinforcing rib 2 at a certain distance; Laemodipodiform reinforcing rib 2 adopts mild steel through hot forging forming, and one end of reinforcing rib and Connection Block are riveted at through hole position and combined, and reinforcement of weld.Laemodipodiform reinforcing rib 2 other end end strikes out herringbone or the dendriform to circumferential bifurcated, during construction, laemodipodiform reinforcing rib 2 bottom U-shaped Superimposed fastener and U-shaped Connection Block 1 are embedded in building substrate (as concrete) in advance, play the effect of connecting building matrix (concrete); Laemodipodiform reinforcing rib end is herringbone or dendriform bifurcated to surrounding, and laemodipodiform reinforcing rib size is thicker gradually from the top down, be conducive to improving the anchoring strength between building substrate (concrete) and reinforcing rib, improve the bearing capacity of Superimposed fastener.
The utility model is not limited to above-described embodiment, and U-shaped Connection Block 1 and laemodipodiform reinforcing rib 2 also can adopt bolt and nut to be connected, or the direct form such as welding, and the downward dendroid form of bifurcation of laemodipodiform reinforcing rib 2 can suitably change.Every on the basis of technical scheme disclosed in the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some technical characteristics wherein to replace and distortion, these are replaced and are out of shape all in the scope of the utility model protection.
