Description

Sound insulation building structure Technical Field The utility model relates to the technical field of building structure devices, in particular to a sound insulation building structure. Background At present, facilities such as a water pump, an air conditioning unit, a fan and the like are commonly used in civil or commercial buildings, noise generated by the equipment is mainly low-frequency noise, the noise frequency range is 63-250Hz, the noise is mainly high in penetrability, and the noise can be transmitted to a far place through the building and air. Because the equipment is generally directly placed on the concrete and rubber cushion block for sound insulation, the sound insulation effect is poor, and the ground sound insulation effect of many buildings is poor, so that vibration and noise generated during the operation of the equipment are easily transmitted through the ground. In the past, the ground is generally reformed, the ground is cut to be paved again or a sound insulation structural layer is additionally paved on the basis of the existing ground to separate the noise of equipment, but the mode has longer construction time, large and complex construction engineering, more various sound insulation construction tools and building materials, high cost and no longer movement or repeated use after construction. Therefore, it is necessary to provide a sound insulation building structure which can be quickly constructed on the existing ground, is convenient to move, can be repeatedly used, and has good sound insulation effect. Disclosure of utility model The utility model provides a sound insulation building structure, which solves the problems in the background technology, and adopts the following technical scheme: The utility model provides a sound insulation building structure, locates on the ground of foundation, foundation subaerial has laid the pitch layer, the structure is including removing lifting mechanism, it has placed multilayer sound insulation structure layer in the lifting mechanism to remove, multilayer sound insulation structure layer is laid on the pitch layer through removing lifting mechanism, multilayer sound insulation structure layer top is equipped with the tray, erect mechanical equipment on the tray is interior, and be equipped with a plurality of spring damper between tray and the mechanical equipment, the top surface of tray four peripheral portion is equipped with the support connection structure who is used for connecting mechanical equipment four sides respectively. Preferably, the spring damping device comprises an upper footstock with a convex-shaped structure and a lower base with a concave-shaped structure, the upper footstock is fixed at the bottom of the mechanical equipment, the lower base is fixed in the tray, the protruding end of the upper footstock is movably abutted with the concave part of the lower base, a spring is sleeved on the outer periphery side of the protruding end of the upper footstock, the upper end of the spring is in contact with the upper footstock, and the lower end of the spring is in contact with the lower base. The upper top seat and the lower base are movably butted with each other to play a role in guiding up and down, so that the phenomenon that mechanical equipment is inclined left and right due to vibration during working is avoided, and the damping effect is realized by matching with a spring. Preferably, the supporting and connecting structure comprises a plurality of lifting lugs I fixed on the top surfaces of four sides of the tray, lifting lugs II corresponding to the lifting lugs I one to one are arranged on the periphery sides of the mechanical equipment respectively, and connecting rods are connected between the lifting lugs I and the lifting lugs II. The connecting rod is used for supporting mechanical equipment, makes the connecting rod through the lug connection, prevents the condition that mechanical equipment during operation leaned over all around, plays simultaneously to the limit for height effect of lower base and last footstock, prevents that the interior concave part of lower base from going up the footstock. Preferably, rubber layers are arranged on the concave part and the upper top surface of the lower base, the outer surface of the lifting lug I and the outer surface of the lifting lug II. The rubber layer is used for preventing the upper top seat from being in direct contact with the lower base to play a role in protection, and preventing the connecting rod from directly colliding with the first lifting lug or the second lifting lug to generate additional noise, and plays a certain damping effect when the upper top seat is in contact with the lower base. Preferably, the movable lifting mechanism comprises a square outer frame body, hydraulic cylinders I are respectively arranged on the peripheral walls inside the outer frame body, a supporting plate is connected to one end, opposite to the outer frame bod
