Description
Technical field the utility model relates to stone bolt Embedment Construction technology such as overlength, a fairly large number of large scale industry building of pre-embedded anchoring bolts and large-scale steel structure basis, particularly relates to a kind of pre-buried overlength whole shaped steel locating rack device of foot bolt fundamentally that is used for.
Background technology for as projects such as large-scale industrial construction such as thermal power plant, plant gas, power station, large-scale steel structure basis and various boiler rooms in construction, it is pre-buried to face the high-strength stone bolt of a lot of large equipment bases, the basic pre-embedded bolt specification of this class building is many, quantity big and construction precision is had relatively high expectations, and has produced normal mounting and the debugging that bigger deviation will directly influence equipment in case bolt is pre-buried individually.
Usually, the main following two kinds of forms of large equipment base built-in process many for the pre-embedded bolt specification, that quantity is big:
1, adopt inner support to fix, the mounting process pre-embedded anchoring bolts of primary concreting concrete location.This method is common built-in process for a fairly large number of Equipment Foundations of pre-embedded anchoring bolts, and its location is relatively accurate, and is pre-buried fair guaranteed.But the inner support of the method is built in Equipment Foundations with pre-buried stone bolt when concreting in the lump for once using, and stone bolt is subjected to the external force effect and is offset in that concreting is appropriate to the occasion, for the installation of equipment is made troubles.
2, adopt support arm to fix, support arm adopts the fulcrum of scaffold building to be arranged at the foundation structure outside, comes pre-embedded anchoring bolts.Its location of this kind built-in process is relatively accurate, and pre-buried quality is better, but if the scaffold large usage quantity that is to use be subjected to construction machinery or personnel's external force effect in construction after, is difficult for checking, reset and adjusting.
Ghana's plant gas first and second phases of projects that my company undertakes the construction of amount to six combustion machine bases, single key dimension 21.3m * 4.0m * 1.3m, the curved anchor of pre-buried 34 M45-772 band, the stone bolt that flat segments 150mm is long.Two on combustion gas basis is in all bases maximum one, single key dimension 22.249m * 7.25m * 2.655m/1.63m/1.0m, the stone bolt of the curved anchor of pre-buried 47 M45 band.Many large equipment bases are piece formula basis independently, have much to give on base surface to bury ironware and give and stay bolt housings or direct-burried bolt; During construction to basic foundation, give embedded part, give and stay absolute altitude, axial location, planeness and the verticality etc. of bolt hole and direct-burried bolt etc. that higher requirement is arranged, particularly foot bolt is installed comparatively dispersion to this project equipment fundamentally, required precision is higher, and boiler foundation, steam turbine pedestal etc. all belongs to concrete in mass.At this basis overlength, pre-embedded anchoring bolts quantity is more and have the characteristics of curved anchor and vibrations, adopts common job practices can't satisfy working procedure and is connected and the duration needs, required precision can't guarantee, does not reach the effect of economic use simultaneously.For this reason, in order to ensure the accuracy of pre-embedded anchoring bolts, I have used whole shaped steel locating rack to come pre-embedded anchoring bolts at company's design.
Utility model content the technical problems to be solved in the utility model is to provide a kind of pre-buried overlength whole shaped steel locating rack device of foot bolt fundamentally that is used for rational in infrastructure, easy to install.Use this device, locating support can be reused, and guarantees the accuracy of pre-embedded anchoring bolts location, and construction cost is low, convenient and quick construction, and installation rate is fast, short construction period.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme of taking: a kind of pre-buried overlength whole shaped steel locating rack device of foot bolt fundamentally that is used for, comprise locating support, locating support comprises that two longerons reach and longeron several crossbeams of getting in touch connected vertically; It is characterized in that: locating support also comprises and longeron several supporting traverses connected vertically, the supporting traverse two ends are positioned at foundation structure periphery, longeron outside, the peripheral position corresponding with the supporting traverse two ends of foundation structure is installed with concrete buttress, fixedlys connected with concrete buttress in the supporting traverse two ends; It is corresponding that longeron sidewall, supporting traverse and get in touch crossbeam and be installed with several location that are used to be connected basic pre-embedded anchoring bolts and choose ear, location are chosen the position of the position of ear and basic pre-embedded anchoring bolts.
The utility model locating support section steel manufacture mainly is to utilize shaped steel support arm system, carries out stone bolt and locatees pre-buried.The fulcrum that is used for fixing the locating support of basic pre-embedded anchoring bolts is that the supporting traverse two ends are fixed on the foundation structure concrete buttress in addition, locating support is on foundation structure, locating support and Equipment Foundations structure break away from fully, choose on the ear wanting pre-buried basic pre-embedded anchoring bolts to be fixed on the location that the shaped steel locating support is provided with.By the processing dimension of control shaped steel locating support and the accuracy of hoisted in position, control the position precision of the horizontal direction of basic pre-embedded anchoring bolts; The up-down adjustment nut on the ear is chosen in the up-down adjustment nut of two screw rods by regulating concrete buttress upper support point steel plate and location, controls the vertical position precision of stone bolt.
Ghana's plant gas first and second phases of projects that the utility model has been undertaken the construction of in my company amount to six combustion machine foundation constructions and use.By to four combustion machines fundamentally the multi-form built-in process contrast of two kinds of foot bolts calculate and analyze, use only four combustion machines, 3.8 ten thousand yuan of the pre-buried way cost savings usually of foot bolt fundamentally of monolithic devices steelframe locating support pre-embedded anchoring bolts construction system.Concrete pouring is finished and is reached detachable locating support after the prescribed strength requirement, and reusable characteristics are arranged, and after all bases finished construction, used shaped steel of shaped steel locating support and nut also can be used for the construction at other position.
Facts have proved employing the utility model, pre-buried position is accurate, and short construction period need be few with equipment, and operating procedure is simple, and surcharge is few.Particularly be applicable to the pre-buried of curved anchor of band and the large equipment base stone bolt that has vibrations.
