Description

Technical Field

[0001] The invention belongs to the technical field of floor slabs, and in particular relates to an assembled composite floor slab with integrated thermal insulation and sound insulation structure. Background Art

[0002] Prefabricated composite floor is a prefabricated building component, usually used in multi-story buildings. Its main feature is that the modular components of the floor prefabricated in the factory are assembled and installed on the construction site, which can effectively improve the efficiency, quality and safety of building construction, while reducing the construction period and labor intensity on the construction site.

[0003] With the continuous development of the construction industry, the design and construction technology of prefabricated composite floors are also constantly improving. However, the existing composite floors still have the following technical problems:

[0004] The thermal insulation effect of the composite floor cannot be adjusted according to the external temperature environment. When the external temperature is high, the thermal insulation effect cannot be properly reduced, resulting in excessive thermal insulation effect, accelerating the aging or deformation of building materials (such as wood, plastic, etc.). When the external temperature is low, the thermal insulation effect cannot be improved, resulting in rapid loss of indoor heat and increased energy consumption for heating and cooling.

[0005] The sound insulation effect cannot be adjusted according to the external sound pressure conditions, and the noise level of the outside world varies greatly in different time periods and activity states. For example, it is quieter at night and noisier during the day, resulting in a relatively low sound insulation effect when the noise level is high during the day, reducing people's comfort and quality of life. When the noise level is low at night, the sound insulation effect is relatively high, resulting in the sound in the indoor space being too dull, which not only affects voice communication, but also poses certain safety hazards, such as not being able to hear the alarm during a fire.

[0006] Therefore, there is an urgent need for a composite floor that can adjust the thermal insulation and sound insulation effects of the composite floor according to the external temperature environment and sound pressure conditions. Summary of the invention

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0016] Preferably, each of the adjusting components comprises a gear fixedly connected to the end of the rotating rod, and a rack meshing with the gear is fixedly connected to the bottom end of the supporting plate in a vertical direction.

[0017] Preferably, each of the lifting force balancing components includes a control disc fixedly connected to the rotating rod, an arc-shaped guide groove is fixedly connected to the side wall of the control disc close to the guide rope wheel, a guide block is fixedly connected to the side wall of the guide rope wheel, the guide block is slidably connected to the inner wall of the arc-shaped guide groove, an electromagnetic spring is provided between the guide block and the inner wall of the arc-shaped guide groove, and a sliding rheostat for controlling the compression degree of the electromagnetic spring is provided on the side wall of the lifting plate.

[0019] Compared with the existing technology, the advantages of this thermal insulation and sound insulation structure integrated assembled composite floor are:

[0020] 1. The present invention provides an adjustment component. When the temperature changes, the ventilation rate of the ventilation steel pipe is adjusted by the thermal expansion and contraction characteristics of kerosene, thereby adjusting the thermal insulation effect by changing the air convection speed: when the outside temperature is high, the convection speed in the hollow layer is increased, so that heat is transferred faster through convection, thereby reducing the thermal insulation performance of the hollow layer and the thermal insulation effect of the composite floor slab, avoiding aging or deformation of building materials due to excessive thermal insulation effect, and improving the durability of the building structure; when the outside temperature is low, the convection speed in the hollow layer is reduced, so that the thermal insulation effect of the hollow layer and the thermal insulation effect of the composite floor slab can be enhanced, the indoor temperature can be maintained, the energy consumption of heating and cooling can be increased, and the effect of energy saving can be achieved.

[0021] 2. The present invention sets an adaptive sound insulation component. When the external sound pressure changes, the sound pressure sensor can collect data in real time, convert the sound wave energy into an electrical signal, and adjust the electric field strength around the deformable sound absorbing member: when the external noise level is high during the day, the sound insulation effect of the deformable sound absorbing member is enhanced, improving people's comfort and quality of life; and when the external noise level is low at night, the sound insulation effect of the deformable sound absorbing member is reduced, avoiding the sound in the indoor space from being too dull, and avoiding safety hazards.

[0022] 3. The present invention sets a lifting assembly and an adjusting component. During lifting, the connecting piece is lifted by the hook at the bottom of the traction rope, and then the composite floor is placed on the shear wall through the lifting vehicle body. Before lifting, the hydraulic rod can be adjusted according to the size of the composite floor, so as to adjust the position of the lifting plate. When the coverage area of ​​the composite floor is larger, the position of the lifting plate is made higher, and the guide rope wheel rotates under the action of the gear and the rack, so that the traction rope is extended more, thereby ensuring that the span at both ends of the two traction ropes increases with the increase of the coverage area of ​​the composite floor, avoiding the small span at both ends of the traction rope, resulting in insufficient stability of the hoisted object during the lifting process, and reducing the risk during the lifting process.

[0023] 4. The present invention can monitor the balance state of the floor slab body through the distance sensors arranged at both ends of the lifting plate by arranging a lifting force balancing component. When it is found that the floor slab body deviates to one side, the electric telescopic rod on that side can be controlled to open, driving the traction rope on that side to be released, so that the weight of the composite floor slab will not be concentrated on one end of the traction rope, so that both ends of the traction rope can always bear the composite floor slab, thereby improving the bearing capacity and service life of the traction rope and ensuring the safety performance during the lifting process.

DETAILED DESCRIPTION

[0031] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0032] Example:

[0033] Reference Figure 1 , Figure 3 and Figure 4 A heat-insulating and sound-insulating structure integrated assembled composite floor comprises a floor body 1, a plurality of connecting pieces 11 distributed in a rectangular array are fixedly connected to the upper end of the floor body 1, a hollow layer 12 having a heat-insulating effect is provided inside the floor body 1, and ventilation steel pipes 13 communicating with the outside are embedded in the inner walls of both sides of the hollow layer 12;

[0034] Specifically, a reinforcing net is fixedly connected to the inner wall of the hollow layer 12. The setting of the reinforcing net makes the hollow layer 12 more stable. Since air itself is a good insulating material with a relatively low thermal conductivity, the setting of the hollow layer 12 can play a role in heat preservation.

[0035] The regulating component 2 is used to adjust the thermal insulation effect of the hollow layer 12 according to the external temperature. The regulating component 2 includes a rubber tube 21 fixedly connected to the end of the ventilation steel pipe 13. The rubber tube 21 is located in the hollow layer 12. An annular liquid storage chamber 22 is fixedly connected to the inner wall of the rubber tube 21. The interior of the annular liquid storage chamber 22 is filled with kerosene with the property of thermal expansion and contraction. A heat-conducting hose 23 in contact with the outside is fixedly connected to the annular liquid storage chamber 22. The interior of the heat-conducting hose 23 is filled with silicone oil with high thermal conductivity.

[0036] Specifically, the heat-conducting hose 23 is made of a metal flexible heat-conducting material (such as a metal fiber material) and extends into the annular liquid storage chamber 22. After the temperature of the outside air is transferred to the heat-conducting hose 23, since the heat-conducting hose 23 and the tube body are filled with silicone oil with a high thermal conductivity coefficient, the heat loss is low during the process of the heat-conducting hose 23 transferring the temperature to the annular liquid storage chamber 22.

[0037] Specifically, the annular liquid storage chamber 22 is made of rubber. When the kerosene inside the annular liquid storage chamber 22 expands due to heat, the annular liquid storage chamber 22 expands in all directions. When the kerosene inside the annular liquid storage chamber 22 contracts due to cold, the annular liquid storage chamber 22 contracts and returns to its original position under the elastic force of the rubber itself. An elastic element can be provided inside the annular liquid storage chamber 22 to assist the annular liquid storage chamber 22 in returning to its original position, thereby ensuring that the kerosene inside the annular liquid storage chamber 22 can return to its original size after contraction.

[0038] In view of the problem that the thermal insulation effect of the composite floor cannot be adjusted according to the external temperature environment in the prior art, the present invention sets an adjustment component 2. When the temperature changes, the ventilation rate of the ventilation steel pipe 13 is adjusted by utilizing the thermal expansion and contraction characteristics of kerosene, thereby adjusting the thermal insulation effect by changing the air convection speed. The specific adjustment process is as follows:

[0039] When the outside temperature is high, the annular liquid storage chamber 22 expands due to the expansion of kerosene, thereby enlarging the rubber tube 21, increasing the air flow through the rubber tube 21 per unit time, increasing the convection speed of the air in the hollow layer 12, and allowing heat to be transferred faster through convection, thereby reducing the insulation performance of the hollow layer 12 and the insulation effect of the composite floor, avoiding aging or deformation of building materials due to excessive insulation effect, and improving the durability of the building structure;

[0040] When the outside temperature is low, the annular liquid storage chamber 22 shrinks due to the contraction of kerosene under the action of the internal elastic element, and the rubber tube 21 becomes smaller, thereby reducing the air flow through the rubber tube 21 per unit time. By reducing the convection velocity in the hollow layer 12, the insulation effect of the hollow layer 12 and the thermal insulation effect of the composite floor can be enhanced, the indoor temperature can be maintained, the energy consumption of heating and cooling can be reduced, and the effect of energy saving can be achieved.

[0041] Reference Figure 1 and Figure 5 The present invention also includes an adaptive sound insulation component 3, which is used to adaptively adjust the sound insulation effect according to the intensity of the noise. The adaptive sound insulation component 3 includes a receiving groove 31 opened at the bottom end of the floor body 1, and a deformable sound absorbing member 32 made of electrodeformable material is fixedly connected to the center position of the receiving groove 31. A control module for adjusting the surface area and shape of the deformable sound absorbing member 32 is provided inside the floor body 1.

[0042] Specifically, the control module includes a microcontroller disposed inside the floor body 1 and a plurality of sound pressure sensors distributed in an array. The microcontroller adjusts the electric field intensity applied to the peripheral side of the deformable sound absorbing member 32 according to the plurality of sound pressure sensors.

[0043] Specifically, the sound pressure sensor uses a sensor that can detect the sound pressure level in real time (such as a MEMS microphone sensor) and has good frequency response characteristics. A microcontroller (such as Arduino, Raspberry Pi, etc.) is used to connect the sound pressure sensor to collect data in real time, and the electric field strength around the deformable sound absorbing member 32 is adjusted in real time according to the collected sound pressure data. The deformable sound absorbing member 32 is made of electrodeformable material. Electrodeformable material is a type of polymer that can change its shape or size under the action of an electric field, so that the deformable sound absorbing member 32 can deform according to the applied electric field, adjust its surface area and shape, and change the propagation path of the sound wave and the sound absorption performance.

[0044] In view of the problem that the sound insulation effect cannot be adjusted according to the external sound pressure in the prior art, the present invention sets an adaptive sound insulation component 3. When the external sound pressure changes, the sound pressure sensor can collect data in real time, convert the sound wave energy into an electrical signal, and adjust the electric field strength around the deformable sound absorbing member 32. The specific adjustment process is as follows:

[0045] When the external noise level is high during the day, the current is automatically increased, so that the deformation degree of the deformable sound absorbing member 32 is increased, its surface area and shape are adjusted, the propagation path of the sound wave and the sound absorption performance are changed, so that the sound insulation effect of the deformable sound absorbing member is enhanced, and people's comfort and quality of life are improved;

[0046] When the external noise level is low at night, the sound insulation effect of the deformable sound absorbing member 32 is reduced, thereby preventing the sound in the indoor space from being too dull and avoiding safety hazards.

[0047] Reference Figure 1 , Figure 2 and Figure 6 The floor slab is assembled using a lifting device, which includes:

[0048] The lifting assembly 4 is used to assemble the floor slab body 1. The lifting assembly 4 includes a lifting vehicle body 41 arranged on one side of the floor slab body 1. The upper end of the lifting vehicle body 41 is fixedly connected to a hydraulic cylinder 42. The top output end of the hydraulic cylinder 42 is fixedly connected to a slide rail 43. A slider 44 and an electric push rod for driving the slider 44 are slidably connected in the slide rail 43. The bottom of the slider 44 is fixedly connected to a support plate 45. The bottom end of the support plate 45 is fixedly connected to a hydraulic rod 46. The telescopic end of the hydraulic rod 46 is fixedly connected to a lifting plate 47. The bottom sides of the lifting plate 47 They are all rotatably connected to a rotating rod 48, each of which is equipped with a guide rope wheel 49, and each guide rope wheel 49 has a plurality of traction ropes 410 wound up on it. The bottom end of each traction rope 410 is provided with a hook 411 that cooperates with the connecting piece 11, and each rotating rod 48 is provided with an adjusting component 5 for adjusting the span and span angle between the traction rope 410 and the floor body 1 to improve the stability during the lifting process. A lifting force balancing component 6 is provided between each rotating rod 48 and the guide rope wheel 49 for preventing the weight of the floor body 1 from being concentrated on the traction rope 410 at one end during the lifting process.

[0049] Specifically, the adjusting component 5 includes a gear 51 fixedly connected to the end of the rotating rod 48 , and a rack 52 meshing with the gear 51 is fixedly connected to the bottom end of the supporting plate 45 in a vertical direction.

[0050] In order to improve the stability of the floor body 1 during the assembly process, the present invention is provided with a hoisting assembly 4 and an adjusting component 5. During hoisting, the connecting member 11 is hoisted by the hook 411 at the bottom end of the traction rope 410, and then the composite floor is placed on the shear wall through the hoisting vehicle body 41. Before hoisting, the hydraulic rod 46 can be adjusted according to the size of the composite floor, so as to adjust the position of the hoisting plate 47. When the coverage area of ​​the composite floor is larger, the position of the hoisting plate 47 is made higher, and the guide rope wheel 49 rotates under the action of the gear 51 and the rack 52, so that the traction rope 410 is released and extended more, thereby ensuring that the span of the two ends of the traction rope 410 on both sides increases with the increase of the coverage area of ​​the composite floor, avoiding the small span of the two ends of the traction rope 410, resulting in insufficient stability of the hoisted object during the hoisting process, and reducing the risk during the hoisting process;

[0051] At the same time, the increase in the position of the lifting plate 47 causes the height of the traction ropes 410 at both ends to also increase during the process of increasing their length, so that the span angle between the traction ropes 410 at both ends will not be too large, ensuring that the span angle of the traction ropes 410 is in a more appropriate position, avoiding excessive span angles that will cause the tension of the traction ropes 410 to increase, avoiding the traction ropes 410 from breaking, and further improving the stability during the lifting process.

[0052] The lifting force balancing component 6 includes a control disc 61 fixedly connected to the rotating rod 48, and an arc-shaped guide groove 62 is fixedly connected to the side wall of the control disc 61 close to the guide rope wheel 49, and a guide block 63 is fixedly connected to the side wall of the guide rope wheel 49. The guide block 63 is slidably connected to the inner wall of the arc-shaped guide groove 62, and an electromagnetic spring 64 is provided between the guide block 63 and the inner wall of the arc-shaped guide groove 62. A sliding rheostat for controlling the compression degree of the electromagnetic spring 64 is provided on the side wall of the lifting plate 47.

[0053] Specifically, the sliding rheostat includes a resistance rod 65 fixedly connected to the side wall of the hanging plate 47, a slider 66 is slidably connected to the resistance rod 65, an electric telescopic rod 67 for controlling the position of the slider 66 on the resistance rod 65 is provided on the side wall of the hanging plate 47, and distance sensors 68 for controlling the electric telescopic rod 67 are provided on both sides of the lower end of the hanging plate 47. The electromagnetic spring 64 is connected in series with the power supply device arranged inside the hanging plate 47 through the resistance rod 65 and the slider 66.

[0054] Specifically, the distance sensor 68 can monitor the position of the lifting plate 47 on both sides of the floor in real time, thereby monitoring the inclination state of the floor, and sending the inclination state of the floor to the microcontroller through an electrical signal, and the microcontroller controls the opening and closing of the electric telescopic rods 67 on both sides, thereby realizing the release of the traction rope 410.

[0055] In order to prevent the weight of the composite floor from being concentrated on one of the traction ropes 410 when the composite floor is shaken due to factors such as wind during assembly, the present invention provides a lifting force balancing component 6, and can monitor the balance state of the floor body 1 through the distance sensors 68 provided at both ends of the lifting plate 47. When it is found that the floor body 1 deviates to one side, the electric telescopic rod 67 on this side can be controlled to open, thereby adjusting the position of the slide 66 on the resistance rod 65, and adjusting the electric field strength around the electromagnetic spring 64 on this side, so that the compression degree of the electromagnetic spring 64 on this side is increased, so that the guide block 63 on this side slides in the arc guide groove 62, so that the guide rope wheel 49 on this side rotates relative to the rotating rod 48, driving the traction rope 410 on this side to be released, so that the weight of the composite floor will not be concentrated on one end of the traction rope 410, so that the two ends of the traction rope 410 can always carry the composite floor, thereby improving the carrying capacity and service life of the traction rope 410, and ensuring the safety performance during the lifting process.

[0056] The present invention can be explained by the following operation mode:

[0057] During the use of the composite floor, when the temperature changes, the ventilation rate of the ventilation steel pipe 13 is adjusted by the thermal expansion and contraction characteristics of kerosene, so as to adjust the thermal insulation effect by changing the air convection speed. When the outside temperature is high, the annular liquid storage chamber 22 expands and becomes larger due to the expansion of kerosene, so that the rubber tube 21 becomes larger, the convection speed in the hollow layer 12 is increased, and the heat is transferred faster through convection, thereby reducing the thermal insulation performance of the hollow layer 12 and the thermal insulation effect of the composite floor. When the outside temperature is low, the annular liquid storage chamber 22 shrinks under the action of the internal elastic element due to the contraction of kerosene, and the convection speed in the hollow layer 12 is reduced, so that the thermal insulation effect of the hollow layer 12 and the thermal insulation effect of the composite floor can be enhanced, the indoor temperature is maintained, the energy consumption of heating and cooling is reduced, and the effect of energy saving is achieved;

[0058] When the external sound pressure changes, the sound pressure sensor can collect data in real time, convert the sound wave energy into an electrical signal, and adjust the electric field strength around the deformable sound absorbing member 32. When the external noise level is high during the day, the current is automatically increased, so that the deformation degree of the deformable sound absorbing member 32 is increased, and its surface area and shape are adjusted, so as to change the propagation path of the sound wave and the sound absorption performance, so that the sound insulation effect of the deformable sound absorbing member is enhanced. When the external noise level is low at night, the sound insulation effect of the deformable sound absorbing member 32 is reduced to avoid the sound in the indoor space being too dull.

[0059] During the assembly of the composite floor, the connecting piece 11 is lifted by the hook 411 at the bottom of the traction rope 410, and then the composite floor is placed on the shear wall by the lifting vehicle body 41. Before lifting, the hydraulic rod 46 can be adjusted according to the size of the composite floor, so as to adjust the position of the lifting plate 47. When the coverage area of ​​the composite floor is larger, the position of the lifting plate 47 is made higher, and the guide rope wheel 49 rotates under the action of the gear 51 and the rack 52, so that the traction rope 410 is extended further, thereby ensuring that the span at both ends of the traction rope 410 increases with the increase of the coverage area of ​​the composite floor. At the same time, the height of the end of the traction rope 410 connected to the guide rope wheel 49 under the lifting plate 47 is increased, so that the span and span angle between the traction ropes 410 at both ends are in a suitable state, thereby improving the stability during the lifting process.
