Description

Technical Field

[0001] The utility model relates to the technical field of building floor vibration isolation, in particular to a lightweight building floor vibration isolation structure. Background Art

[0002] In recent years, the public transportation-guided urban development model has developed rapidly in my country. As a representative of public transportation, the subway has become an important means to solve urban road congestion and reduce air pollution due to its environmental protection, safety and efficiency. In addition, property development above the subway can play a role in the comprehensive utilization of land resources, facilitating people's transportation, and recovering funds to feed back subway construction.

[0003] The vibration waves caused by the frequent operation of subways are transmitted to the buildings above the subway through the building foundations and load-bearing structures. They can easily cause vibration of the floors above the subway and secondary structural noise, affecting people's normal lives, interfering with the normal operation of precision instruments and equipment, and even causing cracks in the building structure. It can be seen that the environmental vibration problem caused by subway train operation on the buildings above the subway is one of the key issues affecting the development of properties above the subway.

[0004] An existing patent (publication number: CN207829149U) discloses a lightweight vibration isolation structure for a building floor. This utility model discloses a lightweight vibration isolation structure for a building floor, which includes frame columns and reinforced concrete floor slabs. The frame columns serve as supports for the reinforced concrete floor slabs. The reinforced concrete floor slabs are arranged layer by layer and at intervals on the frame columns. Slag mortar layers are added to the upper and lower surfaces of the reinforced concrete floor slabs. The thickness of the reinforced concrete floor slabs is 15 cm, and the thickness of the slag mortar layer is 5 cm. On the one hand, this structure effectively reflects the vibration energy back to the foundation of the building, and on the other hand, it can absorb part of the vibration energy, reduce the propagation of the vibration energy in the building, and reduce the vibration impact on the upper cover building. After the lightweight vibration isolation structure of this utility model is set, the vibration attenuation of the subway upper cover building can reach 3-4dB on the lower floors and 6-7dB on the higher floors.

[0005] In response to the above problems, existing patents have provided solutions, but the above patents only propose laying slag mortar layers on the top and bottom of reinforced concrete floor slabs. From the perspective of structural mechanics, if there is no separation and reinforcement structure on the outside and inside of the slag mortar layer, its ability to resist deformation and damage when subjected to vibration and the building's own load may be limited, resulting in general structural strength, affecting the overall stability and durability of the vibration isolation structure. At the same time, the top slag mortar layer is designed only from the perspective of vibration isolation, without considering functions such as sound insulation and thermal insulation. In the context of modern buildings requiring increasingly higher versatility, its practicality may be affected, and it cannot meet some building usage scenarios with high environmental requirements, and thus is not sufficient to meet people's needs.

[0006] Therefore, a lightweight vibration isolation structure for building floors is proposed. Utility Model Content

[0007] The purpose of the present utility model is to provide a lightweight vibration isolation structure for building floors, which can solve the problem that the above-mentioned patent only proposes laying slag mortar layers on the top and bottom of reinforced concrete floor slabs. From the perspective of structural mechanics, if there is no separating reinforcement structure on the outside and inside of the slag mortar layer, its ability to resist deformation and damage when subjected to vibration and the building's own load may be limited, resulting in general structural strength, affecting the overall stability and durability of the vibration isolation structure. At the same time, the top slag mortar layer is designed only from the perspective of vibration isolation, without considering functions such as sound insulation and heat preservation. In the context of modern buildings with increasingly higher requirements for multifunctionality, its practicality may be affected, and it cannot meet some building use scenarios with high environmental requirements, thereby not being able to fully meet people's needs.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a lightweight vibration isolation structure for a building floor, comprising an underground platform, a sleeper provided on the top of the underground platform, a track structure provided on the top of the sleeper, a subway vehicle provided on the top of the track structure, frame columns provided on both sides of the top of the underground platform, reinforced concrete floor slabs provided inside and on both sides of the frame columns, a cushion structure provided on the top of the reinforced concrete floor slabs, a reinforcement mechanism provided on the top of the cushion structure, a slag mortar layer provided inside the reinforcement mechanism, a sound insulation and heat preservation assembly provided on the top of the reinforcement mechanism, and the sound insulation and heat preservation assembly being located on top of the slag mortar layer;

[0009] The reinforcement mechanism includes positioning rods arranged on both sides of the top of the cushion structure, a positioning groove is opened inside the positioning rod, the front and rear sides of the positioning groove are clamped with support rods, and a reinforcement structure is provided inside the positioning groove. The positioning rods, support rods and reinforcement structure are all in contact with the slag mortar layer.

[0010] Preferably, the sound insulation and heat preservation assembly includes a sound insulation layer arranged on top of the positioning rod, the support rod, the reinforcement structure and the slag mortar layer, and the sound insulation layer is made of a composite sound insulation material.

[0011] Preferably, a heat-insulating layer is provided on the top of the sound-insulating layer, and the heat-insulating layer is made of a composite heat-insulating material.

[0012] Preferably, a covering layer is provided on the top of the thermal insulation layer, and the covering layer is made of mud and sand material.

[0013] Preferably, the cushion structure includes a plane layer arranged on the top of the reinforced concrete floor slab, and the top of the plane layer is in contact with the bottom of the positioning rod, the support rod, the reinforcement structure and the slag mortar layer respectively.

[0014] Preferably, an embedded layer is embedded inside the top of the planar layer, and the embedded layer is made of mesh wire material.

[0015] Preferably, the reinforcement structure includes a transverse reinforcement rod arranged inside the positioning groove, the transverse reinforcement rod is in contact with the slag mortar layer, and a reinforcement groove is formed on the top of the transverse reinforcement rod.

[0016] Preferably, a reinforcement rod is clamped inside the reinforcement groove, and the reinforcement rod is in contact with the slag mortar layer.

[0017] Preferably, a flow opening is provided on the outer side of the reinforcement rod, and the flow opening is in the shape of a circular hole.

[0018] Preferably, the reinforcement rod is made of thin aluminum material, and the transverse reinforcement rod is made of hard aluminum material.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The present application sets a reinforcement mechanism. When the slag mortar layer is subjected to vibration and the load of the building itself, the positioning rods, support rods and reinforcement structure in the reinforcement mechanism work together. The positioning rods provide vertical support and positioning for the entire reinforcement system, and the positioning grooves inside them provide installation positions for the support rods and reinforcement structure. The support rods are clamped in the positioning grooves to support the slag mortar layer in the horizontal direction to prevent it from deforming in the horizontal direction. The reinforcement structure further strengthens the constraint on the slag mortar layer in the positioning grooves, so that it can better resist deformation and damage when bearing loads. Since the reinforcement mechanism is in close contact with the slag mortar layer, when the slag mortar layer is subjected to external force, the stress can be transmitted and dispersed through the reinforcement mechanism. The positioning rods transmit the vertical stress to the foundation structures such as the underground platform and frame columns, and the support rods and reinforcement structure disperse the horizontal stress to the surrounding structural components, thereby avoiding excessive local stress in the slag mortar layer and improving the structural strength and overall stability of the slag mortar layer.

[0021] 2. This application incorporates a sound insulation component located on top of the slag mortar layer. When sound waves reach the component, they block and absorb the sound, effectively reducing the transmission of sound from below the floor slab to the interior space above, creating a relatively quiet environment within the building. Furthermore, the component also features low thermal conductivity. When heat is transferred from inside or outside the building to the floor slab, the insulation material hinders the transfer of heat, thereby providing insulation, maintaining a stable internal temperature, and reducing energy consumption.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-6 , this utility model provides a technical solution:

[0031] A lightweight vibration isolation structure for a building floor comprises an underground platform 1, a sleeper 2 being provided on the top of the underground platform 1, a track structure 3 being provided on the top of the sleeper 2, a subway vehicle 4 being provided on the top of the track structure 3, frame columns 5 being provided on both sides of the top of the underground platform 1, reinforced concrete floor slabs 6 being provided inside and on both sides of the frame columns 5, a cushion structure 7 being provided on the top of the reinforced concrete floor slabs 6, a reinforcement mechanism 8 being provided on the top of the cushion structure 7, a slag mortar layer 9 being provided inside the reinforcement mechanism 8, a sound insulation and heat preservation assembly 10 being provided on the top of the reinforcement mechanism 8, and the sound insulation and heat preservation assembly 10 being located on top of the slag mortar layer 9;

[0032] The reinforcement mechanism 8 includes a positioning rod 801 arranged on both sides of the top of the cushion structure 7, a positioning groove 802 is opened inside the positioning rod 801, and support rods 803 are clamped on the front and rear sides of the positioning groove 802. A reinforcement structure 804 is arranged inside the positioning groove 802, and the positioning rod 801, support rod 803 and reinforcement structure 804 are all in contact with the slag mortar layer 9.

[0033] In this embodiment: by setting the reinforcement mechanism 8 formed by the positioning rod 801, the support rod 803 and the reinforcement structure 804, the slag mortar layer 9 is constrained and supported from multiple directions. The positioning rod 801 provides vertical positioning and support, the support rod 803 prevents the slag mortar layer 9 from deforming in the horizontal direction, and the reinforcement structure 804 further enhances the restraint ability of the slag mortar layer 9. This multi-directional reinforcement method enables the slag mortar layer 9 to more effectively resist deformation and damage when subjected to vibration and the building's own load, thereby improving the overall stability and durability of the vibration isolation structure. The setting of the sound insulation component 10 makes up for the deficiency of the prior art that only considers the vibration isolation function. In the context of increasingly higher environmental requirements for modern buildings, this component can effectively reduce sound propagation and provide a quiet environment inside the building. At the same time, it can also play a role in heat preservation, maintain stable indoor temperature, and reduce energy consumption. The setting of the cushion structure 7 provides a better support foundation for the reinforcement mechanism 8 and the slag mortar layer 9, making the connection between the various structural components tighter and more reasonable. The reinforcement mechanism 8 is in close contact with the slag mortar layer 9, which not only enhances the strength of the slag mortar layer 9, but also better transmits and disperses stress. The sound insulation component 10 is located on the top of the slag mortar layer 9 and works in conjunction with other structures to achieve the integration of multiple functions such as vibration isolation, sound insulation and heat preservation.

[0034] Specifically, such as Figure 5 As shown, the sound insulation and heat preservation assembly 10 includes a sound insulation layer 1001 arranged on the top of the positioning rod 801, the support rod 803, the reinforcement structure 804 and the slag mortar layer 9, and the sound insulation layer 1001 is made of composite sound insulation material.

[0035] Specifically, such as Figure 5 As shown, a thermal insulation layer 1002 is provided on the top of the sound insulation layer 1001, and the thermal insulation layer 1002 is made of composite thermal insulation material.

[0036] Specifically, such as Figure 5 As shown, a covering layer 1003 is provided on the top of the thermal insulation layer 1002, and the covering layer 1003 is made of mud and sand material.

[0037] In this embodiment: the sound insulation layer 1001 made of composite sound insulation material can effectively block and absorb sound, reduce the sound propagation from the bottom of the floor to the indoor space above, and provide a quiet environment inside the building. The thermal insulation layer 1002 is made of composite thermal insulation material, which has the characteristics of low thermal conductivity. The special structure inside the composite thermal insulation material, such as the air layer or thermal insulation particles, can reduce heat conduction and heat convection, and hinder the heat from the inside or outside of the building to the floor, thereby playing a role in insulation, maintaining the internal temperature of the building stable, and reducing energy consumption. The capping layer 1003 is made of mud and sand material. It is located on the top of the thermal insulation layer 1002 and protects the thermal insulation layer 1002 to prevent the thermal insulation layer 1002 from being affected by external factors, thereby improving the overall performance and service life.

[0038] Specifically, such as Figure 6 As shown, the cushion structure 7 includes a plane layer 701 arranged on the top of the reinforced concrete floor 6, and the top of the plane layer 701 contacts the bottom of the positioning rod 801, the support rod 803, the reinforcement structure 804 and the slag mortar layer 9 respectively.

[0039] Specifically, such as Figure 6 As shown, an embedded layer 702 is embedded inside the top of the planar layer 701 , and the embedded layer 702 is made of a mesh material.

[0040] In this embodiment: by setting the planar layer 701 on the top of the reinforced concrete floor 6, it is in contact with the positioning rod 801, the support rod 803, the reinforcement structure 804 and the bottom of the slag mortar layer 9 respectively, thereby providing a flat support foundation for these structural components, making the connection between the components tighter and more stable, and the planar layer 701 can evenly transfer loads and vibrations, avoiding uneven structural force due to uneven foundation, thereby improving the performance of the entire vibration isolation structure. At the same time, the embedded layer 702 is made of mesh material and is located on the inner side of the top of the planar layer 701. The mesh material has certain toughness and tensile strength. It can enhance the structural strength of the planar layer 701 to a certain extent, and prevent the planar layer 701 from cracking or deforming when subjected to horizontal force.

[0041] Specifically, such as Figure 4 As shown, the reinforcement structure 804 includes a transverse fixing rod 8041 arranged inside the positioning groove 802, the transverse fixing rod 8041 is in contact with the slag mortar layer 9, and a reinforcement groove 8042 is opened on the top of the transverse fixing rod 8041.

[0042] Specifically, such as Figure 4 As shown, a reinforcement rod 8043 is clamped inside the reinforcement groove 8042, and the reinforcement rod 8043 is in contact with the slag mortar layer 9.

[0043] In this embodiment: by arranging the cross-fixing rod 8041 inside the positioning groove 802 and in contact with the slag mortar layer 9, a reinforcement groove 8042 is opened on its top, and the reinforcement rod 8043 is clamped in the reinforcement groove 8042 and also in contact with the slag mortar layer 9. This structural design enables the cross-fixing rod 8041 and the reinforcement rod 8043 to restrain and support the slag mortar layer 9 from different directions. The cross-fixing rod 8041 mainly provides horizontal support force to prevent the slag mortar layer 9 from deforming in the horizontal direction, and the reinforcement rod 8043 reinforces the slag mortar layer 9 in the vertical direction. The two work together to enhance the structural strength of the slag mortar layer 9, so that it can better resist deformation and damage when subjected to vibration and the building's own load.

[0044] Specifically, such as Figure 4 As shown, a flow opening 11 is opened on the outer side of the reinforcement rod 8043, and the flow opening 11 is in the shape of a circular hole.

[0045] Specifically, such as Figure 4 As shown, the reinforcement rod 8043 is made of thin aluminum material, and the cross-reinforcement rod 8041 is made of hard aluminum material.

[0046] In this embodiment: by opening a flow port 11 on the outside of the reinforcement rod 8043, the slag mortar layer 9 can flow, and the reinforcement rod 8043 is made of thin aluminum material, which has certain strength and toughness. Its strength can provide effective support for the slag mortar layer 9, and its toughness enables it to deform to a certain extent without breaking when bearing load, thereby better adapting to the deformation requirements of the slag mortar layer 9, and at the same time avoiding damage to the slag mortar layer 9 due to excessively hard material. The cross-fixing rod 8041 is made of hard aluminum material, which has high strength and hardness, which enables the cross-fixing rod 8041 to provide stable support force for the slag mortar layer 9 in the horizontal direction, effectively preventing the slag mortar layer 9 from deforming in the horizontal direction, and ensuring the structural integrity and stability of the slag mortar layer 9.

[0047] Working principle: During the use of the lightweight vibration isolation structure of the building floor, the subway vehicle 4 generates vibration waves when running on the track structure 3. The vibration waves are transmitted to the underground platform 1 through the sleepers 2, and then affect the frame columns 5 and the reinforced concrete floor 6. At this time, the plane layer 701, positioning rods 801, support rods 803, cross-fixing rods 8041, reinforcement rods 8043 and slag mortar layer 9 on the top of the reinforced concrete floor 6 work together to reduce the vibration. The slag mortar layer 9 itself has certain vibration isolation performance and can absorb and reflect part of the vibration energy. The positioning rods 801, support rods 803 and the composition of cross-fixing rods 8041 and reinforcement rods 8043 support and constrain the slag mortar layer 9 from multiple directions. When the vibration wave is transmitted to the slag mortar layer 9, it can help the slag mortar layer 9 to better resist deformation, ensure the stable performance of its vibration isolation performance, and effectively reduce the propagation of vibration waves in the building. At the same time, when the sound wave propagates from the bottom of the building to the reinforced concrete floor 6, the The sound insulation layer 1001 on top of the slag mortar layer 9 begins to play a role, effectively blocking and absorbing sound, reducing the propagation of sound to the indoor space above the building, and providing a relatively quiet environment inside the building. The thermal insulation layer 1002 on top of the sound insulation layer 1001 has an insulation effect. At the same time, the covering layer 1003 located on top of the thermal insulation layer 1002 is made of mud and sand materials, which maintains the stability of the internal temperature of the building and reduces energy consumption. In addition, the plane layer 701 provides a flat support foundation for the slag mortar layer 9, which can evenly transfer loads and vibrations. The embedded layer 702 on the inner side of the top of the plane layer 701 is made of mesh material, which enhances the structural strength of the plane layer 701 and prevents it from cracking or deforming when subjected to horizontal forces. At the same time, it improves the bonding force between the plane layer 701 and other structural components. The overall coordination not only enhances the strength of the slag mortar layer 9, but also better transfers and disperses stress, ensuring the stable operation of the entire vibration isolation structure.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
