[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0021] For examples, see Figure 1-4 , the utility model provides a technical solution:
[0022] A stably connected floating foundation comprises a structural floor 1, a leveling layer 2 is arranged on the base surface of the structural floor 1, a waterproof coating layer 3 is arranged on the base surface of the leveling layer 2, a slope layer 4 is arranged on the base surface of the waterproof coating layer 3, a vibration isolation rubber pad 5 is installed on the base surface of the slope layer 4, a galvanized steel plate 6 is arranged on the base surface of the vibration isolation rubber pad 5, a plastic film 7 is arranged on the base surface of the galvanized steel plate 6, a floating platform 8 is arranged on the base surface of the galvanized steel plate 6, a sound insulation cotton pad 9 is arranged on one side of the vibration isolation rubber pad 5, and a surrounding rubber plate 10 is arranged between the floating platform 8 and the structural floor 1.
[0023] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The waterproof coating layer 3 is made of acrylic material, the leveling layer 2 is made of cement mortar material, the slope layer 4 is made of fine stone concrete material, multiple groups of vibration isolation pads 5 are provided and are respectively located on the outer walls of the slope layer 4, the floating platform 8 is made of thick reinforced concrete material, the vibration isolation pad 5 is made of CDM vibration isolation pad material, the sound insulation cotton pad 9 is made of 50mm thick low-density glass fiber / rock wool material, and the thickness of the galvanized steel plate 6 is not less than 2mm.
[0024] The working process of the utility model: when working with the floating foundation with stable connection designed by the scheme, the platform must be kept clean, flat and dry before arranging the vibration isolation glue, and the height difference per square meter area shall not exceed 5mm. All cracks shall be repaired and the residues shall be cleaned. If the original floor is too rough, it shall be treated with a leveling layer 2. The thickness of the leveling layer 2 shall not be less than 20mm. If necessary, a steel bar layer may be added to prevent the leveling layer 2 from breaking under high load. According to the construction drawing, a 200mm high cement edge is poured around the position of the floating platform 8. 20# channel steel can also be used instead of the edge. The vibration isolation glue is glued to the inside of the edge. If the floating platform 8 contacts the wall or column, an edge rubber plate 10 is provided between the floating platform 8 and the structural floor 1.
[0025] Before the construction of the vibration isolation pad 5, first clean the site where the floating platform 8 needs to be installed, remove the uneven concrete surface or metal exposed part below the ground and wall surface height, and then use high-resistance mortar to level the ground to the height required by the building design. The surface of the surrounding walls also needs to be leveled to ensure that the platform is flat and should not be uneven, undulating, or misaligned. Pay special attention to the flatness of the ground at the position of the vibration isolation pad 5, use ink lines to lay out the ground, pre-set the position of the vibration isolation pad 5, and then use a small amount of universal glue to stick the vibration isolation pad 5 to the fixed position. The painted surface of the vibration isolation pad 5 must face up. Finally, verify any discrepancies between the drawings and the construction site and revise them. If the wall is irregular, it must be ensured that the distance between the edge of the vibration isolation pad 5 and the edge of the wall does not exceed 100mm. If it exceeds, an additional row of vibration isolation pads 5 must be added;
[0026] The gaps between the vibration-isolating glues are filled with 50 mm thick low-density sound-absorbing materials (glass fiber / rock wool), and the sound-isolating cotton pads 9 are filled to achieve a good physical sound-isolating effect, which is similar to the effect of a sound-absorbing wall. This is passive sound insulation, and combined with the active sound insulation of the floating platform 8, the effects are superimposed, making the vibration-reducing and sound-isolating advantages of the floating platform 8 more obvious.
[0027] By laying the galvanized steel plates 6 with a thickness of not less than 2mm on the channel steel one by one in a certain order, it must be ensured that the steel plates are free of rust and have a flat surface. The galvanized steel plates 6 are single-piece plates. The galvanized steel plates 6 are fixed by spot welding after being butted against each other. The interval between the welding points of the joints is not more than 300mm, and the width of the joints is not more than 3mm, so as to improve the connection strength between the galvanized steel plates 6 and avoid the compression deformation of the seams of the galvanized steel plates 6. The location of the spot welding should avoid the vibration isolation pads 5 to avoid burning the vibration isolation. The welding points should be painted with anti-corrosion paint. The joints of the galvanized steel plates 6 should be T-shaped, and there should be no cross joints. This can reduce the number of joints and make the corners of the galvanized steel plates 6 not easy to sink and deform. In order to ensure the overall flatness of the surface of the galvanized steel plates 6, the galvanized steel plates 6 cannot be overlapped up and down;
[0028] After the galvanized steel plate 6 is laid, a waterproof layer is laid on it. The waterproof layer material is plastic film 7, which has good waterproof performance and is easy to construct. The laying direction of the plastic film 7 should be along the wind direction, and the overlapping length should not be less than 100mm. Before laying, the sundries on the galvanized steel plate 6 should be cleaned, the laying position should be accurate, and it should be fixed with adhesive tape after laying. The plastic film 7 must be flat and firm without damage. The waterproof layer of the plastic film 7 should be higher than the surrounding edge and closed at its outer edge facade to prevent leakage during concrete pouring;
[0029] When pouring concrete, it should be done in layers and sections. The pouring height of each layer should be determined according to the structural characteristics and the density of steel bars. Concrete pouring should be done continuously. If it must be interrupted, the interval time should be shortened as much as possible, and the second layer of concrete should be poured before the initial setting of the previous layer of concrete. Generally, if it exceeds 2 hours, it should be treated as a construction joint. When pouring concrete, a special person should be assigned to regularly observe the formwork, steel bars, reserved openings, embedded parts, and inserted bars for displacement changes or blockage. If any problems are found, the pouring should be stopped immediately, and the repairs should be completed before the initial setting of the poured concrete. During the concrete pouring, the position of the column and the position of the embedded parts should be checked in time. The poured floor slab can only be operated on it after the concrete reaches 1.2MPa. The concrete should be covered within 12 hours after pouring and watered for maintenance;
[0030] The places where the floating platform 8 contacts the structural floor 1 need to be isolated from the rigid connection with an elastic edge rubber sheet 10 of about 10 mm thickness. The edge rubber sheet 10 must be laid flat, close to the wall, and the interface should be minimized. The laying height should be 200 mm higher than the concrete surface. After the concrete layer is constructed, cut the raised part, and then apply sealant on its surface to seal it;
[0031] The floating platform 8 is composed of an elastic layer and a floating layer on the surface of the building structure floor 1. The floating layer is cast by reinforced concrete, and the elastic layer is composed of elastic supporting members. The floating platform 8 is essentially an active vibration isolation method to isolate the sound source from the building. The floating structure of the floor has good effects on active vibration isolation and noise reduction and passive vibration isolation for power equipment and instruments, which is beneficial to solving the current construction field. As a vibration isolation structure, the floating platform has some limitations in practical applications. Specifically, on-site feedback and engineering practice show that the vibration reduction effect of the existing floating platform is not ideal, and it is difficult to meet the increasingly stringent vibration isolation standards and requirements. Due to the limitations of their design and materials, these platforms cannot effectively isolate and reduce vibration and impact from the ground, and have poor practicality.
