Abstract
The utility model discloses a major diameter rag bolt, the tool comprises a scre, the both ends of screw rod all are equipped with the external screw thread, the bottom threaded connection two nuts of screw rod, screw rod lower margin iron of threaded connection still between two nuts, two nuts respectively with the welding of lower margin iron, the utility model discloses an avoid cutting the main part reinforcing bar, destroy structural stability to subtract the step of cutting off the reinforcing bar rewelding and resumeing the reinforcing bar, reduce work hours and mechanical input, improved the installation effectiveness, and be favorable to the adjustment of rag bolt precision, the effectual precision of controlling rag bolt.
Description
Technical field
The utility model relates to a kind of stone bolt of large industrial buildings engineering, particularly a kind of major diameter stone bolt.
Background technique
In large industrial buildings, have a large amount of bolt to need pre-buried, wherein the take the weight tangent beam of circle that carries and pre-embedded bolt have following construction features: beam section is high; Reinforcing bar is intensive; The diameter of bolt is large, quality weight; Bolt quantity is many; Bolt embedment required precision is high.Traditional stone bolt all comprises screw rod and lower margin iron usually, but because the screw rod of stone bolt and lower margin iron weld together before the mounting, and reinforcing mesh in large industrial buildings is intensive, when mounted, first stone bolt is put into reinforcing bar just inside the beam of colligation, such lower margin iron is easily encountered on dense reinforcing bar, this just needs to cut off reinforcing bar, recover by the method for welding after cutting off out, overall large diameter pre-embedded bolt quality weight, use special tool or employ crane.This method not only spends a large amount of manpowers and machinery, and the speed of installation is slow, and work efficiency is low, and due to reinforcing bar intensive, precision adjustment is slow, and bolt molding effect is poor.
Model utility content
Technical problem to be solved in the utility model is to provide major diameter stone bolt and the installation method thereof that a kind of efficiency is high, be easy to operation.
For achieving the above object, the utility model provides following technological scheme: a kind of major diameter stone bolt, comprises screw rod, and the two ends of described screw rod are equipped with outside thread, the bottom thread of screw rod connects two nuts, and screw rod is also threaded plot pin iron between two nuts.
Preferably, two nuts weld with lower margin iron respectively.
Adopt technique scheme, during installation, screw rod and lower margin iron are independently installed, avoid needing to cut off reinforcing bar and weld the step recovering reinforcing bar again, avoid destroying structure stability, simplify operation, cost-saving, reduce work hours and the input of machinery, reduce difficulty of construction, improve installation efficiency.And be conducive to the adjustment of stone bolt precision, do not destroying on the basis of structure reinforcing bars, effectively controlling the precision of stone bolt.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein, 1. screw rod 2. nut 3. lower margin iron 4. reinforcing mesh.
Embodiment
Below in conjunction with accompanying drawing, by the description to embodiment, the utility model is described further:
As shown in Figure 1, a kind of major diameter stone bolt of the utility model, comprise screw rod 1, the two ends of screw rod 1 are equipped with outside thread, and the bottom thread of screw rod 1 connects two nuts 2, screw rod 1 is also threaded plot pin iron 3 between two nuts 2, the mode be threaded connection connects lower margin iron 3, makes lower margin iron 3 become detachable connection, is convenient to location and installs, two nuts 2 weld with lower margin iron 3 respectively, in order to guarantee the fixing of lower margin iron 3.
Its installation method step is as follows:
1). screw rod 1 is positioned;
2). screw rod 1 is inserted into and pricks in the reinforcement cage 4 that bound round, and use tied silk to be fixed by screw rod 1;
3). from reinforcement cage 4 bottom screw rod 1 side operation, successively at bottom thread place tightening nut 2, lower margin iron 3, the nut 2 of screw rod 1;
4). the end face of two nuts 2 is welded with the end face of lower margin iron 3 respectively;
5). the position of screw rod 1 is finely tuned, in order to ensure the highi degree of accuracy of screw rod 1.
Lower margin iron 3 and screw rod 1 are first split recombinant by the utility model, avoid needing to cut off reinforcing bar and weld the step recovering reinforcing bar again, simplify operation, cost-saving, reduce work hours and the input of machinery, reduce difficulty of construction, improve installation efficiency.And be conducive to the adjustment of stone bolt precision, do not destroying on the basis of structure reinforcing bars, effectively controlling the precision of stone bolt.In addition, the positioning work due to the utility model stone bolt carries out in high-altitude, simplifies operation and can reduce the dangerous operation time, reduces security risk factor, guarantee the safety that high-altitude is located.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
