Abstract
The invention discloses a kind of installation method of major diameter foundation bolt, its step is：1) screw rod is positioned；2) screw rod having good positioning is inserted into the steel reinforcement cage pricked and bound round, and is fixed screw rod using tied silk；3) operated from steel reinforcement cage close to the side of screw rod bottom, successively clamp nut, lower margin iron, nut at the bottom thread of screw rod；4) end face of the end face of two nuts respectively with lower margin iron is welded；5) position of screw rod is finely adjusted.The present invention destroys structural stability, the step of recovering reinforcing bar is welded again so as to subtract and cut off reinforcing bar to avoid cuts main body reinforcing bar, reduce work hours and machinery input, installation effectiveness is improved, and is conducive to the adjustment of foundation bolt precision, is effectively controlled the precision of foundation bolt.
Description
Technical field
The present invention relates to a kind of foundation bolt of large industrial buildings engineering, more particularly to a kind of major diameter foundation bolt
Installation method.
Background technology
In large industrial buildings, there is substantial amounts of bolt to need pre-buried, wherein the circular tangent beam for the load that takes the weight and in advance
Burying bolt has following construction features：Beam section is high；Reinforcing bar is intensive；The diameter of bolt is big, quality weight；Bolt quantity is more；Bolt embedment
Required precision is high.Traditional foundation bolt usually all includes screw rod and lower margin iron, but due to the screw rod and lower margin of foundation bolt
Iron is welded to together before the mounting, and the bar-mat reinforcement in large industrial buildings is intensive, when mounted, first foundation bolt
It is put into inside the beam that reinforcing bar is being bound, such lower margin iron is easily encountered on dense reinforcing bar, this is just to need to cut off reinforcing bar, is cut
Recovered after removing out with the method for welding, the pre-embedded bolt quality weight of overall major diameter, to use specific purpose tool or employ crane.
This method not only spends substantial amounts of manpower and machinery, and the speed of installation is slow, and work efficiency is low, and since reinforcing bar is intensive, precision tune
Whole slow, bolt molding effect is poor.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of peace of efficient, easily operated major diameter foundation bolt
Dress method.
To achieve the above object, the present invention provides following technical solution：A kind of installation method of major diameter foundation bolt,
The major diameter foundation bolt includes screw rod, and the both ends of the screw rod are equipped with external screw thread, and the bottom thread of screw rod connects two spiral shells
Mother, screw rod are also threadedly coupled plot foot iron between two nuts, and two nuts are welded with lower margin iron respectively, the major diameter
The installation method of foot bolt comprises the following steps：
1) positions screw rod；
2) screw rod is inserted into the steel reinforcement cage pricked and bound round by, and is fixed screw rod using tied silk；
3) is operated from steel reinforcement cage close to the side of screw rod bottom, successively clamp nut, lower margin at the bottom thread of screw rod
Iron, nut；
4) welds end face of the end face of two nuts respectively with lower margin iron；
5) is finely adjusted the position of screw rod.
Using above-mentioned technical proposal, when installation, is independently installed by screw rod and lower margin iron, avoids the need for cutting off reinforcing bar and welds again
Recover reinforcing bar the step of, avoid damage to structural stability, simplify process, it is cost-effective, reduce work hours and machinery input,
Difficulty of construction is reduced, improves installation effectiveness.And be conducive to the adjustment of foundation bolt precision, do not destroying the base of structure reinforcing bars
On plinth, the precision of foundation bolt is effectively controlled.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Wherein, 1. screw rod, 2. nut, 3. lower margin iron, 4. bar-mat reinforcement.
Embodiment
Below in conjunction with the accompanying drawings, by the description of the embodiment, the present invention will be further described：
As shown in Figure 1, a kind of major diameter foundation bolt of the present invention, including screw rod 1, the both ends of screw rod 1 are equipped with external screw thread,
The bottom thread of screw rod 1 connects two nuts 2, and screw rod 1 is also threadedly coupled plot foot iron 3 between two nuts 2, passes through spiral shell
The mode of line connection connects lower margin iron 3, lower margin iron 3 is changed into detachable connection, easy to position and install, two nuts 2
Welded respectively with lower margin iron 3, to ensure the fixation of lower margin iron 3.
Its installation method step is as follows：
1) positions screw rod 1；
2) screw rod 1 is inserted into the steel reinforcement cage 4 pricked and bound round by, and is fixed screw rod 1 using tied silk；
3) from steel reinforcement cage 4 close to 1 bottom of screw rod side operate, successively at the bottom thread of screw rod 1 clamp nut 2,
Lower margin iron 3, nut 2；
4) welds end face of the end face of two nuts 2 respectively with lower margin iron 3；
5) is finely adjusted the position of screw rod 1, to ensure the high accuracy of screw rod 1.
Lower margin iron 3 and screw rod 1 are first split recombinant by the present invention, avoid the need for cutting off the step that reinforcing bar welds recovery reinforcing bar again
Suddenly, simplify process, it is cost-effective, reduce work hours and machinery input, reduce difficulty of construction, improve installation effectiveness.
And be conducive to the adjustment of foundation bolt precision, on the basis of structure reinforcing bars are not destroyed, it is effectively controlled the essence of foundation bolt
Degree.Further, since the positioning work of foundation bolt of the present invention is carried out in high-altitude, when dangerous operation can be reduced by simplifying process
Between, reduce security risk factor, it is ensured that the safety of high-altitude positioning.
Above-described is only the preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention
Protection domain.
