Abstract
The utility model relates to a vibration isolation construction technology for an equipment foundation, in particular to a vibration isolation and noise reduction equipment foundation of steel frame floating construction. Aiming at the defects of not really ideal vibration isolation effect, complicated technological process, long construction period, high cost, large load of floor slabs, complicated processing of waterproof joints on the roof, incapability of avoiding forced vibration and resonance of the floor slabs, large noise radiating surface and the like of the existing vibration isolation method by concrete base slab floating construction which is float-constructed on a structural building or the base slab, the vibration isolation and noise reduction equipment foundation of the steel frame floating construction connects the steel frame on a concrete structure column or a buttress directly, a vibration isolator is arranged between the equipment and the steel frame, thus realizing double vibration isolation by the steel frame and the vibration isolator, avoiding the forced vibration of the floor slabs effectively, and avoiding indoor noise due to the vibration of the floor slabs and ensuring the safety of the structure; and the equipment foundation has short construction period and is convenient, economical and practical.
Description
Technical field
The utility model relates to Equipment Foundations vibration isolation construction technology, relates in particular to a kind of steelframe " floating building " vibration isolation, noise reducing apparatus basis, improves acoustic environment in the building.
Background technology
Work units such as the air source heat pump that in modern architecture, is equipped with, blower fan, cooling tower, water pump, be installed in mostly on roofing, the floor floor, the vibration of these Large-power High-Speed running devices and consequent noise have brought very big influence for the normal use of building.In order to obtain better damping, noise reduction, usually adopt concrete floor " floating building " basis to carry out vibration isolation in the design and construction, with flexible material Equipment Foundations and building structure beam slab are separated, but its floating building on structure floor, vibration isolating effect is not satisfactory, has that complex technical process, long construction period, cost height, floor load are big, roof waterproof node processing complexity, can not avoid defectives such as floor forced vibration and resonance and noise radiation face are big.
Summary of the invention
The utility model is not satisfactory at current device " floating building " vibration insulating foundation vibration isolating effect, long construction period, the cost height, the floor load is big, can not avoid defectives such as floor forced vibration and resonance and noise radiation face are big, the structural column vertical rigidity is big having analyzed, the floor vertical rigidity is little, on the good basis of air vibration isolating effect, a kind of steelframe of utility model " floating building " vibration isolation, the construction method on noise reducing apparatus basis, use vibration isolator, " floating building " vibration isolation system that section steel beam is formed replaces existing floating Equipment Foundations of building on floor, with the air is the flexible class vibration isolation materials such as rubber that vibration isolation material replaces conventional floating underpin, actual conditions and equipment mounting condition according to engineering structures, adopt the capital buttress, modes such as anchor steel plate or bracket are installed steelframe behind the post limit, to the demanding application scenario of noise reduction, the power transmission point that is connected with post at steelframe is provided with the neoprene bearing pad, form the obstruct point of solid-borne sound transmission, to obtain acoustic environment in the better building.Steelframe of the present utility model " floating building " vibration isolation, noise reduction are constructed from heavy and light, and it is less to take up room, and is easy to install in roofing, floor, and short construction period, construction technology is simple, makes building obtain better acoustic environment, and can not produce damage to the building structure beam slab.
The technical solution of the utility model is:
Steelframe " floating building " vibration isolation, noise reducing apparatus basis, it is characterized in that mainly comprising vibration isolator, steelframe and Zhi Dun, described steelframe is made up of section steel beam, it is basic primary structure member equipment is quiet, that dynamic load passes to structure vertical members such as post, shear wall, also be partiting polarization component, it is connected with the structure vertical member; Described vibration isolator is arranged between equipment and the steelframe.This device carries out directly passing on great structural column of vertical rigidity or the shear wall behind the two-stage vibration isolation to the equipment exciting force, replaces existing floating Equipment Foundations of building on floor, and steelframe and structure beam slab separate.Steelframe is made up of section steel beam, is basic primary structure member equipment is quiet, that dynamic load passes to structure vertical members such as post, shear wall, also is partiting polarization component.
Described steelframe is connected the employing roof and adds capital buttress, post limit pre-embedded steel slab or add modes such as back anchor steel plate or post limit bracket with the structure vertical member.
Described section steel beam is i iron, channel-section steel or welding rectangle girder steel, is determined by intensity, rigidity and Cable Power Computation.In the steelframe design and installation process, should consider to reduce rigidity under intensity and the stability condition satisfying as far as possible.Many beams shelving same equipment need the length unanimity, guarantee the rigidity unanimity, avoid torsional oscillation.。
Described vibration isolator is determined its model and number by designing and calculating, each vibration isolator want stressed substantially symmetrically.To prevent " vibration short circuit " phenomenon during installation.
As preferably, truss-steel beam should adopt the shaped steel of cross section symmetry, as i iron, welding rectangle steel.
The utlity model has following advantage:
1, twice vibration isolation, vibration insulation and noise reduction are effective.After the disturbance process vibration isolator of vibratory equipment, the steelframe vibration isolation, the disturbance that is delivered to the basis is very little, i.e. the transmission of isolation mounting is than very little, and the noise measured value is lower than the requirement of related standards.
2, the strong point of vibration isolation system is on concrete column.The vertical dynamic stiffness of concrete column is bigger, is not easy to produce forced vibration and resonance.
3 steelframes are from heavy and light, and it is less to take up room, and are easy to install in roofing, floor.And short construction period, construction technology is simple, the convenient application.
4 avoid the easily aging shortcoming that becomes " firmly " of traditional rubber vibration insulating pad, prolong the cycle of maintenance of equipment, reduce maintenance cost; Help improving the service life of equipment, save the secondary input and the running cost of capital.
5 with respect to other vibration isolating methods, and the utility model makes building obtain better acoustic environment, and can not produce damage to the building structure beam slab.
Description of drawings:
Fig. 1 is the utility model structural representation;
Wherein: 1 steelframe, 2 vibration isolators, 3 pre-buried or back anchor steel plates, 4 neoprene bearing pads, 5 buttresses, 6 posts, 7 beams, 8 equipment.
