The beneficial effect of the utility model: the requirement of rag bolt position can be satisfied, the requirement of rag bolt anchor power can be satisfied again.
Description
Technical field
The utility model relates to equipment mounting technique field, is specifically related to a kind of adjustable type stone bolt.
Background technology
In engineering construction job site, a lot of visual plant, for ensureing installation accuracy, all adopts backup land bolt holes mode, mounting foot bolt while treating equipment installation, and therefore, anchor bolt box center deviation is very large on precision of equipment installation impact.For various reasons, the anchor bolt box handed in civil engineering unit all can the quality problems such as the larger or reserved hole wall out of plumb of location deviation, stone bolt is caused to install not in place, be difficult to meet equipment installation requirement, if carry out hole milling again to the preformed hole exceeding deviation, will the significant wastage of construction delay and manpower and materials be caused, destroy concrete foundation quality simultaneously, cause potential safety hazard, and due to foundation failure, the problem such as easily cause that backing plate is installed nowhere.In view of the foregoing, be necessary to provide a kind of novel stone bolt mounting means, reduce the requirement to anchor bolt box deviation, cost-saving, improve efficiency of construction.
Summary of the invention
The technical problems to be solved in the utility model is, in view of the foregoing defects the prior art has, provides a kind of adjustable type stone bolt, can foot bolt status requirement contentedly, again can foot bolt anchored force requirement contentedly.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of adjustable type stone bolt, comprises bolt lower margin, steel washer, described steel washer is provided with elongated hole, and the bolt of long stem of bolt lower margin is equipped with by elongated hole and steel washer, and bolt lower margin is positioned in preformed hole together with steel washer, and bolt lower margin is under steel washer.
By such scheme, described elongated hole is long lumbar hole.
The utility model has following beneficial effect:
1, adopt adjustable type stone bolt, can effectively solve anchor bolt box offset issue;
2, by adjustable type stone bolt, stone bolt installation difficulty can be reduced, can foot bolt status requirement contentedly, again can foot bolt anchored force requirement contentedly, ensure installation quality, save construction cost, improve efficiency of construction.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model adjustable type stone bolt;
Fig. 2 is the top view of Fig. 1;
In figure, 1-bolt lower margin, 2-preformed hole, 3-steel washer, 4-elongated hole.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
With reference to shown in Fig. 1 ~ Fig. 2, adjustable type stone bolt described in the utility model, comprise bolt lower margin 1, steel washer 3, described steel washer 3 is provided with elongated hole 4, the bolt of long stem of bolt lower margin 1 is equipped with by elongated hole 4 and steel washer 3, bolt lower margin 1 is positioned in preformed hole 2 together with steel washer 3, and bolt lower margin 1 is steel washer 3 times.
Described elongated hole 4 is long lumbar hole.
The installation steps of the utility model adjustable type stone bolt:
1) make steel washer 3 according to the size and dimension of preformed hole 2, the thickness of steel washer 3 should calculate according to the stressing conditions of bolt lower margin 1 to be determined;
2) arrange one elongated hole 4 at steel washer 3 center, the size of elongated hole 4 should match with stone bolt 1 diameter;
3) when installing, bolt lower margin 1 is inserted in the elongated hole 4 of steel washer 3, bolt lower margin 1 is put into anchor bolt box 2 together with steel washer, according to the position of actual deviation adjustment bolt lower margin 1 in the elongated hole 4 of steel washer 3, bolt lower margin 1 is made to reach installation site;
4) after equipment installation in position, carry out preliminary centering, accurate adjustment is carried out to bolt lower margin 1 simultaneously, be located at the center of plant bottom case bolt hole, and ensure that stone bolt 1 is in plumbness;
5) once grouting is carried out to bolt lower margin 1, complete whole work that bolt lower margin 1 is installed.
Above-describedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalence change that the utility model claim is done, still belong to protection domain of the present utility model.
