Technical Field
The application relates to a fastener for building, concretely relates to column base bolt mounting structure.
Background
In the traditional building method, the scheme of embedding the column base bolt is adopted for mounting the column base bolt in most cases. The general steps are that a column base bolt is pre-embedded in a concrete foundation short column during foundation construction, then a column of equipment is installed on the column base bolt, and the column of the equipment is kept stable by the column base bolt and a temporary windproof cable.
Along with the development of modularization factory building, no longer be single post installation in a module, generally have four posts at least in a module, many have 6 or 8 posts, module width more than 4 meters, length can reach 4 ~ 15 meters. And each column base is provided with two bolt holes at a small number, and is provided with 4-8 bolt holes at a large number. In consideration of manufacturing errors and other reasons, the requirement for opening holes in the column base plate is large (the diameter of the column base plate is larger than that of a bolt by no more than 6mm according to national standards), a base plate is additionally used, and the column base plate is welded with the column base plate in a construction site to transmit column base load to the bolt and a foundation, so that materials are increased, and site welding work is increased. When the whole module is installed together, all column bases can be hardly installed by adopting the embedded bolts. In fact, the accuracy of stud installation is difficult to guarantee, and the resulting large amount of field modifications have become a common quality problem.

In at least one embodiment, the post is welded to the column shoe bottom plate, the column shoe bolt mounting structure further comprising a clamp nut, the column shoe bolt being connected to the column shoe bottom plate by the clamp nut.
In at least one embodiment, the column shoe bottom plate is spaced from the top surface of the foundation column.
In at least one embodiment, the bottom of the stud bolt preformed hole has a space from the lower end of the stud bolt.
In at least one embodiment, the stud bolt prepared hole has a size larger than that of the stud bolt in a direction perpendicular to an extending direction of the stud bolt, and the stud bolt is fixed to the stud bolt prepared hole by grout curing.
Through embedding the column base bolt into the column base bolt preformed hole of the foundation short column, the column base bolt can be easily aligned with the column base bolt preformed hole, thereby ensuring simple and accurate installation of the column and the foundation short column corresponding to the column base bolt and the column base bolt preformed hole, respectively.
Drawings
Fig. 1 is a schematic view of a stud bolt mounting structure provided in the present application.
Detailed Description
Exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that the detailed description is only intended to teach one skilled in the art how to practice the present application, and is not intended to be exhaustive or to limit the scope of the application.
As shown in fig. 1, the present application provides a non-pre-buried formula column base bolt mounting structure, and this column base bolt mounting structure includes post 1, column base bottom plate 2, column base bolt 3, clamping nut 4, column base bolt preformed hole 5, foundation short column 6, pre-buried adjusting bolt 7, adjusting nut 8, backup pad 9.
The column 1 represents an equipment part connected with a foundation and can be an I-shaped steel column, the column base bottom plate 2 can be welded with the column 1 in advance before being hoisted to a designed position, and a hole for the column base bolt 3 to penetrate through is formed in the column base bottom plate 2. The foundation post 6 is a concrete or reinforced concrete foundation post which is cast in place or cast before being delivered to the site, the size of the foundation post 6 is determined according to the size of the pillar 1, for example, a 200mm x 200mm pillar 1 can be matched with a 600 x 600mm foundation post 6. Wherein, reserved column base bolt preformed hole 5 in foundation short column 6 relevant position, column base bolt preformed hole 5's cross section can be circular or square, in the direction perpendicular with column base bolt 3's extending direction, column base bolt preformed hole 5's size is greater than column base bolt 3's size, makes column base bolt 3 can adjust the position in column base bolt preformed hole 5. And after the column base is installed, grouting materials such as fine gravel concrete and the like can be utilized for secondary grouting to the column base bolt preformed hole 5.
The embedded adjusting bolt 7, the supporting plate 9 and the adjusting nut 8 are matched for use, leveling and elevation are carried out through the supporting plate 9 and the lower nut of the adjusting nut 8, the upper nut of the adjusting nut 8 is screwed down after the leveling and elevation are finished, and the column base bottom plate 2 meets the designed leveling requirement and elevation requirement. The embedded adjusting bolts 7 can be embedded in the foundation studs 6 before being transported to the site.
The clamp nut 4 denotes upper and lower nuts of the column shoe bolt 3, which are used to fasten the column shoe bolt 3 to the column shoe base plate 2. It will be understood that one of the upper and lower nuts, particularly the lower nut, of the clamping nut 4 may be replaced with another structure fixed to the stud bolt 3 or the stud bolt 3 itself, as long as the upper nut can cooperate with the structure to fasten the column shoe base plate 2 to the stud bolt 3.
A denotes a secondary grouting thickness reserved for the toe box 2 and the top surface of the foundation stub 6 (foundation top surface), and the thickness a is preferably not less than 50 mm. B represents the distance between the lower end of the stud bolt 3 and the bottom of the stud bolt preformed hole 5 after the installation is completed, as long as the distance is such that the bottom of the stud bolt preformed hole 5 does not affect the installation of the stud bolt 3, which in extreme cases may even be close to 0.
The present application also provides a stud bolt installation method for the above stud bolt installation structure, which may include the steps described below.
After the column 1 and the column base plate 2 are suspended, the column base bolt 3 is mounted on the column base plate 2 by the clamp nut 4.
The column 1, the column base bottom plate 2 and the column base bolt 3 are hung to a designed position, and the column base bolt 3 is inserted into the column base bolt preformed hole 5.
Through backup pad 9 and lower part adjusting nut 8, adjust the height of column foot bottom plate 2 to the design height, the level reaches the design requirement, screws up adjusting nut 8, accomplishes leveling and elevation step. When the column 1 and the column shoe base plate 2 are heavy, the column shoe base plate 2 and the support plate 9 can be fixed by spot welding along the outer edge of the column shoe base plate 2.
Grouting and curing the gap between the column base plate 2 and the top surface of the foundation short column 6 and the bolt preformed hole 5, and fixing the column base bolt 3 embedded into the column base bolt preformed hole 5.
It will be appreciated that the stud bolt 3 in the present application includes other similar structures that may function as a threaded bolt. For example, the stud bolt 3 may not necessarily have a thread, and it may be attached to the column base plate 2 at an installation site or at a factory by welding or the like. At least in this case, the clamping nut 4 is not necessary.
The above description of the support plate 9 is only one preferred example of the support plate of the present application. The support plate of the present application may be fixed to the foundation stub 6 and coupled with the column shoe base plate 2 in various forms. The height of the support plate relative to the base stub 6 may or may not be adjustable. The height adjustment function can be achieved by providing a shim plate between the column shoe bottom plate 2 and the support plate, or the column 1 can be brought to a predetermined height by setting the foundation stub 6 to a suitable height.
While the present application has been described with reference to exemplary embodiments, it is to be understood that the present application is not limited to the disclosed exemplary embodiments. Various modifications and alterations of the above-described embodiments may be made by those skilled in the art in light of the teachings of this application without departing from the scope thereof.
