Abstract
The present invention relates to technical field of building construction, the processing method of specifically a kind of equipment basic pre-buried bolt thread curtailment.Including pre-embedded bolt is cut off from screw thread, position is cut off below secondary grout layer, special processing factory is taken into the upper half and adds straight screw sleeve, an equal diameter bolt is taken all to cut off threaded portion, it is held out against with former pre-embedded bolt in straight screw sleeve middle position and is tightened, straight screw sleeve upper and lower opening is fully welded with lengthening threaded rod and pre-embedded bolt respectively, entire sleeve is poured into secondary grout layer or less after the installation is completed by equipment.Construction method of the present invention is simple, easy to operate, does not destroy existing equipment basis, and intensity is up to standard, can effectively save labour turnover and material cost, shortens the construction period, reduces construction cost.
Description
Technical field
The present invention relates to technical field of building construction, the place of specifically a kind of equipment basic pre-buried bolt thread curtailment
Reason method.
Background technique
The saying of " high bolt low embedded part " is known as in construction, in order to avoid foundation settlement when equipment basic pre-buried bolt
Bolt thread curtailment is caused, bolt absolute altitude can improve 0-20mm than design height, but in actual operation, can be because of measurement
The case where reasons such as human error, design mistake, foundation settlement is excessive cause equipment basic pre-buried bolt thread curtailment, leads
Cause nut when equipment installation that can not be fully screwed into.
Currently used conventional methods are all to cut bolt surrounding concrete, again pre- after bolt is integrally taken out
It burying, this method not only elapsed time, waste material and can cut off obstacle reinforcing bar in operation, influence basic integral strength, or
Person cuts off bolt piece longer bolt of direct butt welding, but this method welding difficulty is big, not can guarantee bolt strength, if not
Change bolt, reduce equipment absolute altitude, it will cause coupled other equipment will drop absolute altitude simultaneously, and difficulty of construction increases.
Summary of the invention
Present invention seek to address that the above problem, to provide a kind of construction is simple, easy to operate, proof strength, shorten work
Phase, reduce cost equipment basic pre-buried bolt thread curtailment processing method.
The present invention solves described problem, the technical solution adopted is that:
A kind of processing method of equipment basic pre-buried bolt thread curtailment, includes the following steps:
(1) pre-embedded bolt is cut off from screw thread, and polished flat, cut off position below secondary grout layer；
(2) upper half screw rod cut off is taken into special processing factory and processes straight screw sleeve；
(3) it takes an equal diameter bolt all to cut off threaded portion, and the threaded rod cut off is polished flat, as lengthening
Threaded rod；
(4) lengthening threaded rod is held out against with original pre-embedded bolt in straight screw sleeve middle position and is tightened；
(5) straight screw sleeve upper and lower opening is fully welded welding with lengthening threaded rod and pre-embedded bolt respectively；
(6) entire straight screw sleeve is poured into secondary grout layer or less after the installation is completed by equipment.
The present invention by adopting the above technical scheme, compared with prior art, the feature protruded is:
Construction method is simple, easy to operate, do not destroy existing equipment basis, intensity is up to standard, can effectively save labour turnover and
Material cost shortens the construction period, reduces construction cost.
Preferably, the further technical solution of the present invention is:
Pre-embedded bolt is cut off to the screw thread at least retaining straight screw sleeve half length from screw thread.

Specific embodiment:
Below with reference to embodiment, the invention will be further described, and purpose, which is only that, more fully understands the content of present invention, therefore, institute
The example of act is not intended to limit protection scope of the present invention.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, a kind of place of equipment basic pre-buried bolt thread curtailment
Reason method, includes the following steps:
(1) pre-embedded bolt 8 being embedded in concrete equipment basis 7 is cut off from screw thread, and polished flat, cut off position
In secondary grout layer 6 hereinafter, simultaneously at least retaining the screw thread of 5 half length of straight screw sleeve.
(2) upper half screw rod cut off is taken into the high-intensitive straight screw sleeve 5 of special processing factory's processing.
(3) it takes an equal diameter bolt all to cut off threaded portion, and the threaded rod cut off is polished flat, as
Lengthen threaded rod 1.
(4) threaded rod 1 will be lengthened with torque spanner to tighten in straight screw sleeve 5 with original pre-embedded bolt 8, and make
Threaded rod 1 is lengthened to hold out against with original pre-embedded bolt 8 in 5 middle position of straight screw sleeve.
(5) 5 upper and lower opening of straight screw sleeve is fully welded welding and done and reinforced with lengthening threaded rod 1 and pre-embedded bolt 8 respectively, welded
It is careful not to hurt base material when connecing.
(6) by 3 fixed equipment pedestal 4 of the lengthening threaded rod 1 of pre-embedded bolt 8, nut 2 and gasket, after the installation is completed will
Entire straight screw sleeve 5 is poured into 6 or less secondary grout layer.
Construction method of the present invention is simple, easy to operate, does not destroy existing equipment basis, intensity is up to standard, can effectively save
Cost of labor and material cost shorten the construction period, reduce construction cost.
The foregoing is merely preferably feasible embodiment of the invention, not thereby limiting the scope of the invention,
It is all to use equivalence changes made by description of the invention and its accompanying drawing content, it is intended to be included within the scope of the present invention.
