Description
Technical Field
The utility model relates to a rag bolt positioner in the building engineering field is mainly applicable to industry and civil construction steel construction post and basic connection fixed.
Background
At present, reinforced concrete is adopted for the foundation of any structure, the steel column foundation section of a steel structure or a reinforced concrete structure needs to realize the transition from the foundation to the structure through foundation bolts, the foundation bolts for connection are embedded in the concrete foundation through the bottom, and the upper portion of the foundation bolts is connected to the steel column bolt holes and fixed at the bottom of a steel column. The embedded anchor bolts are usually selected and arranged according to the positions and the number of bolt holes for fixing an upper steel column in the process, most of the existing embedded bolts are fixed by one isolated embedded bolt at one time, a combination system is rarely adopted for fixing the embedded bolts of one steel column, one bolt is firstly fixed, and then the bolts are connected into a whole, although some fixing measures are temporarily adopted, the supporting mode for temporary fixing is based on bottom steel of a foundation base plate, bottom steel bars are supported on a cushion layer through cushion blocks, and the positions of the cushion blocks and the bottom steel bars are not fixedly connected, so that the positions of the cushion blocks can be deviated in subsequent processes, and the accuracy of the positioning and elevation of the embedded anchor bolts is influenced; on the other hand, the fixing mode has the following defects: the labor cost for measuring, positioning and subsequent reinforcing is high, the material cost of supporting materials, welding rods and the like is not low, and the labor cost and the material cost are higher than those for fixing a plurality of embedded bolts as a whole.
Disclosure of Invention
In order to solve the defects existing in the installation of the pre-ground bolt embedded in the existing foundation section steel column, a ground bolt positioning device is provided, which comprises 4 supporting vertical rods and a horizontal reinforcing sleeve, wherein the bottom of each supporting vertical rod is provided with a round steel, the upper end of each supporting vertical rod is provided with a nut sleeve with internal threads, the nut sleeves are welded at the top of the round steel, the horizontal reinforcing sleeve consists of 4 sections of strip steel with equal length and 4 steel pipes with equal length, the inner diameter of each steel pipe is 1mm larger than that of each supporting round steel, the width of each steel pipe is consistent with the length of each steel pipe, the steel pipes are welded and connected, the 4 supporting vertical rods penetrate through the round steel pipes of the horizontal reinforcing sleeve and are fixed on the corresponding supporting vertical rods at the lower ends of the nut sleeves by electric welding, a ground bolt is directly screwed in the nut sleeve at the top of the supporting vertical rods of the device through the screw threads of the lower sections of the ground bolt, the, thereby realizing that the elevation of the foundation bolt is basically consistent.
Drawings
The present invention will be further explained with reference to the accompanying drawings.
FIG. 1 is a structural diagram of a foundation bolt positioning device
In the figure, 1-1 nut sleeve 1-2 round steel 2-1 steel bar 2-2 steel pipe;
FIG. 2 is a front elevation view of a foundation bolt positioning device
In the figure, a supporting upright rod 1-1, a nut sleeve 1-2, round steel 2, a horizontal positioning sleeve 3 and a concrete cushion layer are shown.
Detailed Description
1. Selecting the specification of a nut sleeve of a vertical rod of the positioning device according to the specification of the embedded foundation bolt of the steel structure column, and meeting the requirement that the internal thread of the nut sleeve is consistent with the screw rod at the lower end of the embedded foundation;
2. selecting a round steel with a proper specification according to the selected nut sleeve, wherein the diameter of the round steel is 2mm larger than the inner diameter of the nut sleeve, the nut sleeve and the round steel are conveniently welded and connected, the length of the round steel is 20cm, and the round steel and the nut sleeve are welded and connected;
3. selecting a steel pipe in the horizontal reinforcing sleeve according to the specification of the embedded foundation bolt, wherein the specification of the steel pipe is 2mm larger than the outer diameter of the foundation bolt, the length of the steel pipe is 50mm, and selecting bar steel with the same width, wherein the length meets the requirement that the center distance of the adjacent steel pipe is consistent with the center distance of the two adjacent foundation bolts after the steel pipe is welded;
4. welding the steel pipes and the bar steel, firstly welding the two steel pipes at the two ends of the two bar steel, and then fixing the two welded bar steel with the steel pipes at the end parts according to the position relation of the foundation bolts;
5. the remaining 2 steel bars are welded, and the steel bars and the original steel bars form an included angle of 90 degrees and are welded on the steel pipe, so that the horizontal positioning sleeve is processed;
6. measuring and positioning the center of the embedded foundation bolt on the foundation cushion layer, and marking the occupation of the foundation bolt by using a circle;
7. drilling holes by using a hole drilling machine according to the anchor bolt occupation mark, wherein the hole diameter of the drilled holes is slightly larger than the diameter of round steel for supporting the upright stanchion by 1mm, and placing a horizontal positioning sleeve in alignment with the hole position;
8. the positioning sleeve penetrates through the positioning sleeve, the four supporting vertical rods are respectively inserted, glue is injected into gaps of the cushion layer, and the supporting vertical rods are anchored;
9. after the verticality of the supporting vertical rod is adjusted, the horizontal positioning sleeve is lifted upwards to the lower end of the nut sleeve, and the steel pipe of the positioning sleeve is welded and fixed on the supporting round steel, so that the positioning device is machined and installed;
10. the foundation bolts are directly screwed on the nut sleeves of the device, and the installation and the positioning of the embedded foundation bolts can be completed.
