Description

A kind of outdoor pole body construction method

technical field

The invention belongs to the field of building construction, in particular to an outdoor pole body construction method.

Background technique

At present, the foundation needs to be prepared before the pole is erected, the floor flange and anchor bolts are pre-embedded, and the concrete plane foundation is leveled. After confirming that the rod body is vertical, tighten the flange with nuts to fix the rod body. Since the concrete plane is generally a cement plastered surface, the levelness is not high; the flange at the bottom of the rod body is mostly welded, and the levelness cannot be guaranteed due to welding reasons or the unevenness of the metal bottom of the flange itself. The perpendicularity between the rod body and the bottom surface is caused to deviate, and after the rod body is fixed, it is very inconvenient to fine-tune the rod body.

Contents of the invention

In order to overcome the deficiencies in the prior art, the present invention provides an outdoor pole construction method. The method has simple and convenient operation steps, solves the problem of rapid adjustment of verticality in outdoor pole construction, and gets rid of the defects of foundation construction and materials themselves.

Step 3, pour concrete in the pit where the anchor bolt cage is placed in step 2 so that the space below the flange of the base plate is filled with concrete and keep the anchor bolts in a vertical state during the pouring process;

Step 4. After maintaining the concrete poured in step 3 for 3 to 4 weeks, install a first nut on the threaded part of each anchor bolt above the flange of the base plate, and then install a nut on the flange of the base plate. An inflatable cushion device is placed on it, and the inflatable cushion device includes four independent inflatable cushions and a controller connected to each of the inflatable cushions, and the four independent inflatable cushions are evenly placed on the flange of the bottom plate Above the plate, the controller is provided with four buttons, which respectively control the inflation and deflation of the four inflatable cushions;

Step 5. Install the rod body, that is, put the rod body flange on the anchor bolts and the rod body flange is located above the four inflatable pads and the plurality of first nuts, and then pass through the four Inflate and deflate the inflatable cushion to adjust the verticality of the rod body. When the vertical instrument measures that the rod body is in a vertical state and the rod body flange is on the same level as the ground plane, the adjustment is located under the rod body flange. The first nuts make the plurality of first nuts support the rod body, then screw on the second nuts that fix the flange of the rod body, so that the rod body is in a fixed state, and then the air in the four inflatable cushions is completely released And pull it out from under the flange of the rod body;

Step 6: Carry out the second pouring of concrete so that the gap between the flange of the rod body and the flange of the bottom plate is filled with concrete.

Preferably, in the outdoor pole construction method, the inflatable cushion is a high-pressure inflatable cushion.

Preferably, in the above-mentioned outdoor rod body construction method, the specific structure of the anchor bolt cage is: the bottom flange is provided with a plurality of bolt holes penetrating the bottom flange, and the number of the bolt holes is The number of the anchor bolts is equal, the upper ends of the plurality of anchor bolts are all provided with first external threads, a nut is fitted outside the first external threads and a port of the nut is closed, the The inner surface of the nut is provided with an internal thread adapted to the first external thread on the upper end of the anchor bolt, and the outer surface of the nut is provided with a second external thread, and the length of the nut is 100% of the upper end of each anchor bolt. 2/3 of the length of the first external thread, the upper end of each anchor bolt passes through the bolt hole of the flange of the bottom plate and a second nut is arranged under the flange of the bottom plate for fixing, the bottom plate The nut is screwed on the top of the flange for fixing, and the first nut in the step 4 is installed on the nut.

Preferably, in the outdoor rod body construction method, before step 3, a protective cover is placed above the bottom plate flange of the anchor bolt cage to protect the threaded part of the anchor bolt, and the cross-sectional shape of the protective cover is Set in accordance with the cross-sectional shape of the bottom plate flange.

Preferably, in the construction method for the outdoor pole body, the protective cover is made of pearl cotton material, and a foam material is arranged inside the protective cover.

Preferably, in the above-mentioned outdoor pole body construction method, the lower end of each anchor bolt is in the shape of a letter S along the longitudinal axis of the anchor bolt.

Preferably, in the construction method for the outdoor pole body, the number of the anchor bolts is 4, 6 or 8.

Preferably, in the outdoor rod body construction method, a flat washer and a spring washer are arranged between the rod body flange and the second nut, and before the second nut is screwed in in step 5, the flat washer and the spring washer are first screwed in , and then screw in the second nut.

Preferably, in the construction method for the outdoor pole body, a protective layer is provided on the surface of the anchor bolts, and the protective layer is a multi-element alloy co-infiltration layer.

Compared with the prior art, the outdoor rod body construction method described in the present invention, one is to increase the first nut and the inflatable cushion device placed on the flange of the bottom plate, and adjust the verticality of the rod body through the inflatable cushion device. When the vertical instrument measures that the rod body is vertical, tighten the first nut and the second nut to fix the rod body. The inflation and deflation process of the inflatable cushion is easy to control and can be adjusted precisely. The flange plate was not leveled during the first concrete pouring. At this time, just adjust the rod body vertically, fix it and then perform the second concrete pouring, so it is more accurate, and it can also save manpower. Single or double cooperation can Can get the job done. The second is to add a nut to the threaded part of the anchor bolt. The outer surface of the nut is also provided with external threads, so the nut can play the role of tightening and fixing the flange of the bottom plate. The flange of the rod body is set on the nut. The first nut and the second nut above can fix it. Since the threaded part is exposed to the outside after a long period of use, it is easy to be damaged. If the external thread on the nut is damaged, it can be replaced without pulling out the whole nut. The anchor bolts can still be used again, which is simple and convenient. Third, the shape of the lower end of the anchor bolt is S-shaped, which increases the contact area between the lower end of the anchor bolt and the concrete foundation, and the anchor bolt is fixed stably and reliably.
