Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated floor slabs, and specifically relates to a building thermal insulation and energy-saving prefabricated floor slab and its assembly method. Background Technique

[0002] In the prefabricated building industry, some precast components are produced in factories and then assembled at the construction site. Factory standardized production, controllable quality, high efficiency, fast speed, and no waste of materials can achieve improving construction efficiency, increasing the reuse rate of formwork, reducing environmental pollution, and ensuring the quality and safety of buildings. During the hoisting and assembly of existing prefabricated floor slabs, it is necessary to ensure that the gaps between every two adjacent floor slabs are the same and the two ends are aligned to reduce subsequent processes such as caulking and repair. However, during the current hoisting process, since the lifting tool is supported by flexible steel cables, small-range offsets are likely to occur during the hoisting and transfer process, resulting in deviations in the gaps between two adjacent floor slabs and requiring multiple adjustments, which greatly reduces the construction efficiency.

[0003] For example, a prefabricated floor slab and a prefabricated floor slab joint structure disclosed in the publication number CN212295249U can greatly improve the shear resistance and compressive resistance of the floor slab. However, during the hoisting process, the stepped notch lacks effective guidance and requires multiple adjustments to complete, increasing the assembly difficulty. The prefabricated floor slab connection structure disclosed in the publication number CN208309944U, although assembled by the mutual cooperation between the installation holes and the fixing nails, still requires multiple adjustments during the hoisting process to align them, and there is still the problem of low construction efficiency.

[0004] Therefore, a building thermal insulation and energy-saving prefabricated floor slab and its assembly method are proposed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a building thermal insulation and energy-saving prefabricated floor slab and its assembly method, which solves the problems raised in the background technique.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A building thermal insulation and energy-saving prefabricated floor slab includes a precast floor slab body filled with thermal insulation materials. Assembly holes are provided on the side walls of the floor slab body, and connection blocks are arranged on the side walls of the floor slab body. A connection component for assisting hoisting, a limiting component for keeping the floor slab body in a horizontal state during hoisting, and an assembly component for assembling the floor slab bodies together after hoisting are arranged in the floor slab body. The connection component includes:

[0007] Fixed rods, both ends of which are fixed in the floor slab body to provide support for the connection component;

[0008] The support frame, the bottom of which is slidably arranged in the fixing rod and the assembly hole, provides support for the limit assembly;

[0015] Preferably, the limit assembly includes: a limit block slidably mounted in the guide plate and having a return spring fixed at one end; a guide groove provided on the side wall of the guide block and cooperating with the limit block to limit the swing angle of the floor body.

[0016] Preferably, the assembly component includes: an auxiliary block, the side wall of which is fixed on the side wall of the fixing rod; a driving plate, one end of which is slidably inserted into the connecting block and the bottom cooperates with the auxiliary block to move upward under the drive of the auxiliary block; a spring 2, one end of which is fixed on the top of the driving plate and the other end is fixed on the connecting block to provide a downward elastic force to the driving plate.

[0017] Preferably, the assembly component also includes: a fixed sleeve, which is slidably arranged in the connecting block and has a sliding groove on the outer wall of the inner ring; a sliding column, one end of which is fixed to the connecting block and the other end is slidably arranged in the sliding groove to limit the moving direction of the fixed sleeve.

[0018] Preferably, the assembly component further includes: a mounting block with its side wall fixed to the side wall of the fixed rod; a positioning rod with one end slidably passing through the mounting block and being clamped into the fixed sleeve under an external force to restrict the movement of two adjacent floor slab bodies; and a third spring with one end fixed to one end of the positioning rod and the other end fixed inside the mounting block to provide the elastic force required for the positioning rod to reset.

[0019] The present invention also provides an assembly method for a building thermal insulation and energy-saving prefabricated floor slab, including the following steps:

[0025] Preferably, the distance that the sliding plate and the guiding plate move under the drive of the guiding block is between 0 - 5 cm.

[0026] The present invention provides a building thermal insulation and energy-saving prefabricated floor slab and its assembly method. Compared with the prior art, it has the following beneficial effects:

[0027] (1). For this building thermal insulation and energy-saving prefabricated floor slab and its assembly method, the previous floor slab body provides guidance for the subsequent floor slabs through the connection component, enabling quick and accurate positioning and alignment during hoisting, reducing the time for manual adjustment, avoiding repeated position adjustments due to floor slab inclination or misalignment, improving the installation speed, preventing the newly hoisted floor slabs from tilting or sliding forward and backward, reducing the safety risks in high-altitude operations, ensuring that the joints between each floor slab are uniform and flat, contributing to improving the overall building quality. After the floor slabs are assembled, the connection component can be automatically unlocked, facilitating removal and reuse, saving material costs. The connection component is standardized and modular, easy to maintain, replace, and uniformly manage, shortening the construction period, and indirectly reducing energy consumption and carbon emissions.

[0028] (2) The building heat-insulating and energy-saving prefabricated floor slab and its assembling method can effectively restrain the deflection of the floor slab in the left-right direction, ensure its accurate alignment, and avoid the inclined state when the floor slab body is hoisted to the same horizontal plane as the previous floor slab body, which may cause misalignment and bring difficulties to the subsequent assembling work. It helps to achieve high-precision splicing, reduce subsequent processes such as caulking and repairing, reduce the thermal bridge effect and air infiltration, improve the building's heat-insulating and energy-saving performance, and can significantly improve the stability, safety and assembling accuracy during the hoisting process of the prefabricated floor slab.

[0029] (3) The building heat-insulating and energy-saving prefabricated floor slab and its assembling method can automatically complete the assembling action after the floor slab arrives, without manual operation for fastening or alignment, saving a large amount of labor and time, forming a stable structural system, improving the overall bearing capacity and seismic performance, ensuring the same connection state for each floor slab, reducing human errors, realizing standardized and modular construction, carrying out hoisting and assembling integrally, accelerating the overall construction progress, especially suitable for high-rise buildings and projects with tight construction periods. Cooperating with the BIM system, robotic hoisting equipment and automatic control system, it realizes the intelligent construction of prefabricated buildings, not only achieving the fast, accurate and stable connection of prefabricated floor slabs, but also greatly improving the construction efficiency, quality and safety.

[0030] Other features and advantages of the present invention will be described in the subsequent specification, and part of them will become obvious from the specification or be understood by implementing the present invention.

DETAILED DESCRIPTION

[0044] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0045] In the embodiments of the present application, the devices or elements referred to or implied must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise precisely and specifically specified.

[0046] See also Figures 1 to 12 , the present invention provides the following technical solutions:

[0047] Embodiment 1: A building insulation energy-saving assembled floor, comprising a prefabricated floor body 1 filled with insulation material, an assembly hole is opened on the side wall of the floor body 1, a connecting block 39 is arranged on the side wall of the floor body 1, and a connecting component for auxiliary lifting, a limiting component for keeping the floor body 1 in a horizontal state during lifting, and an assembly component for assembling the floor body 1 after lifting are arranged in the floor body 1, and the connecting component comprises: a fixing rod 2, a mounting plate 21, a mounting shaft 22, a toggle rod 23, a fixing block 24, a spring 25, a support frame 26, a movable shaft 27, a limiting rod 28, a sliding plate 29, a guide plate 210, a connecting rod 212, a guide block 213, a limiting groove 214, and a plug plate 216.

[0048] Both ends of the fixing rod 2 are fixedly installed in the floor body 1, and the fixing rod 2 is used to provide support for the connecting assembly. The top of the mounting plate 21 is fixedly installed on the bottom of the fixing rod 2, and both ends of the mounting shaft 22 are hingedly connected to the side walls of the mounting plate 21 through a torsion spring. The toggle rod 23 is fixedly penetrated on the mounting shaft 22, and the toggle rod 23 unlocks the support frame 26 under the action of external force. One end of the fixing block 24 is slidably penetrated in the support frame 26, and the fixing block 24 is used to fix the support frame 26 on the fixing rod 2. One end of the spring 25 is fixedly installed on the fixing On the side wall of the fixed block 24, the other end of the spring 1 25 is fixedly installed in the support frame 26, and the spring 1 25 is used to provide elastic force for returning the fixed block 24. The bottom of the support frame 26 is slidably penetrated in the fixed rod 2 and the assembly hole. The support frame 26 is used to provide support for the limit assembly and the assembly assembly. The bottom of the movable shaft 27 is hingedly installed on the top of the support frame 26 through a torsion spring. The bottom of the limit rod 28 is fixedly installed on the top of the movable shaft 27. The limit rod 28 changes its angle under the drive of the sliding plate 29, thereby limiting the moving direction of the guide block 213.

[0049] One end of the sliding plate 29 is slidably inserted into the support frame 26, and the sliding plate 29 is used to limit the position of the floor body 1. The bottom of the guide plate 210 is fixedly installed on the top of the sliding plate 29, and the guide plate 210 can move under the drive of the sliding plate 29. One end of the connecting rod 212 is fixedly installed on the side wall of the support frame 26, and the connecting rod 212 is used to provide support for the guide block 213. The side wall of the guide block 213 is fixedly installed on the other end of the connecting rod 212. The guide block 213 cooperates with the sliding plate 29 to limit the moving direction of the floor body 1. The limiting groove 214 is opened on the side wall of the guide block 213, and the limiting groove 214 is adapted to the limiting rod 28 to limit the position of the guide block 213. The top of the plug plate 216 is fixedly installed on the bottom of the guide block 213. The plug plate 216 is used to drive the toggle rod 23 to move and unlock the support frame 26.

[0050] In use, the floor slab body 1 is made of mortar and steel materials, with an assembly hole left on one side and a connecting block 39 made on the other side symmetric to it. At the same time, the floor slab body 1 is filled with heat-insulating materials and coated with a heat-insulating coating. During the process of hoisting the floor slab body 1 into a building with a frame structure, the floor slab body 1 is fixed by a hoisting device and then hoisted;

[0051] Before hoisting, the pre-prepared connecting components are installed into the floor slab body 1. The support frame 26 is inserted into the fixing rod 2. Under the action of the first spring 25, the fixing block 24 pops out of the support frame 26 and snaps into the fixing rod 2, thus completing the fixation. The support frame 26 provides a supporting force to the connecting rod 212, the connecting rod 212 provides a supporting force to the guiding block 213. At the same time, the support frame 26 provides a supporting force to the sliding plate 29 and the movable shaft 27, the sliding plate 29 provides a supporting force to the guiding plate 210, and the movable shaft 27 provides a supporting force to the limiting rod 28;

[0052] When hoisting the first floor slab body 1 in a row, construction workers are needed to assist in placing it at the preset position. When hoisting the second floor slab body 1 in this row, the guiding block 213 on the current floor slab body 1 is aligned with the support frame 26 on the previous floor slab body 1. Then, by controlling the hoisting device, the currently hoisted floor slab body 1 is moved towards the previous floor slab body 1, so that the guiding block 213 on the current floor slab body 1 is snapped into the sliding plate 29 and the guiding plate 210 of the support frame 26 on the previous floor slab body 1. And the guiding block 213 on the current floor slab body 1 pushes the sliding plate 29 and the guiding plate 210 to move towards the side where the previous floor slab body 1 is located. Through the sliding fit between the sliding plate 29 and the support frame 26, the sliding plate 29 can only move linearly along the support frame 26 under the action of an external force. When the sliding plate 29 and the guiding plate 210 move linearly along the support frame 26 under the push of the guiding block 213, one end of the limiting rod 28 is pushed by the guiding plate 210 to move. With the movable shaft 27 providing a supporting force to the limiting rod 28, the limiting rod 28 can be flipped with the movable shaft 27 as the axis under the push of the guiding plate 210, so that the other end of the limiting rod 28 is snapped into the limiting groove 214 of the guiding plate 210. At the same time, there is a sliding fit between the limiting rod 28 and the limiting groove 214. At this time, the floor slab body 1 can no longer be moved horizontally, but is lowered from top to bottom to the same horizontal plane. Through the mutual cooperation between the limiting rod 28 and the limiting groove 214, and the mutual cooperation between the sliding plate 29, the guiding plate 210 and the guiding block 213, the floor slab body 1 is prevented from tilting forward and backward at the angle shown during the descending and assembling process; Figure 1 That is, it flips with the connecting rod 212 as the axis;

[0053] When the current floor slab body 1 being hoisted is lowered to a parallel state with the previous floor slab body 1, that is, when the top surfaces are at the same horizontal plane, the insertion plate 216 at the bottom of the guide block 213 on the floor slab body 1 being hoisted will insert along the hole in the middle of the fixed rod 2. By pushing the insertion plate 216, the toggle lever 23 is moved, and the mounting shaft 22 provides a supporting force for the toggle lever 23, and the mounting plate 21 provides a supporting force for the mounting shaft 22, so that the toggle lever 23 rotates around the mounting shaft 22 under the push of the insertion plate 216. When rotating, the end of the toggle lever 23 located inside the fixed rod 2 squeezes the inclined surface at the bottom of the fixed block 24, so that the fixed block 24 retracts into the support frame 26 from the fixed rod 2 under the squeezing of the toggle lever 23. At this time, the support frame 26 on the previous floor slab body 1 can be removed together with other connection components;

[0054] In another embodiment different from the foregoing embodiment, the number of the support frames 26 and the guide blocks 213 is increased, so that the number of the unilateral support frames 26 and the guide blocks 213 is three groups or other numbers. However, multiple groups of support frames 26 are all connected inside the fixed rod 2 through the support frames 26 shown in Figure 1 By increasing the number of connection components, the stability of the floor slab body 1 during the descending process is improved, and it will not deflect forward and backward.

[0055] The technical solution of this embodiment different from the foregoing embodiment includes: a limiting component for keeping the floor slab body 1 in a horizontal state during hoisting is arranged inside the floor slab body 1. The limiting component includes: a limiting block 211, a return spring, and a guide groove 215. One end of the limiting block 211 is slidably installed inside the guide plate 210, and a return spring is fixedly installed at one end of the limiting block 211. The other end of the return spring is fixedly installed inside the guide plate 210. The return spring is used to provide a restoring elastic force for the limiting block 211. The guide groove 215 is opened on the side wall of the guide block 213, and the cooperation between the guide groove 215 and the limiting block 211 limits the swing angle of the floor slab body 1.

[0056] During use, during the hoisting alignment process, when the guide block 213 on the current floor slab body 1 is caught in the sliding plate 29 on the previous floor slab body 1, the guide block 213 first squeezes the limiting block 211 to make the limiting block 211 retract into the guide plate 210. When the guide block 213 is completely caught in the sliding plate 29, the limiting block 211 just corresponds to the guide groove 215. Subsequently, under the action of the return spring, the limiting block 211 pops out of the guide plate 210 and is caught in the guide groove 215;

[0057] After the limiting block 211 is caught in the guide groove 215, through the mutual limitation between the limiting block 211 and the guide groove 215, then control the hoisting equipment to lower the floor slab body 1 to the same height as the previous floor slab body 1.

[0058] The technical solutions of this embodiment different from the foregoing embodiments include: An assembly component for assembling the floor slab body 1 after hoisting is provided in the floor slab body 1. The assembly component includes: an auxiliary block 3, a driving plate 31, a second spring 32, a fixed sleeve 33, a sliding column 34, a sliding groove 35, a positioning rod 36, a third spring 37, and a mounting block 38;

[0059] The side wall of the auxiliary block 3 is fixedly installed on the side wall of the fixed rod 2. One end of the driving plate 31 slides through the connecting block 39, and the bottom of the driving plate 31 cooperates with the auxiliary block 3. The driving plate 31 can move upward under the drive of the auxiliary block 3. One end of the second spring 32 is fixedly installed on the top of the driving plate 31, and the other end of the second spring 32 is fixedly installed on the connecting block 39. The second spring 32 is used to provide a downward elastic force to the driving plate 31. The fixed sleeve 33 is slidably arranged in the connecting block 39, and a sliding groove 35 is opened on the outer wall of the inner ring of the fixed sleeve 33. One end of the sliding column 34 is fixedly installed on the connecting block 39, and the other end of the sliding column 34 slides through the sliding groove 35. The sliding column 34 is used to limit the moving direction of the fixed sleeve 33. One end of the positioning rod 36 slides through the mounting block 38. The positioning rod 36 can be locked into the fixed sleeve 33 under the action of an external force to limit the movement of two adjacent floor slab bodies 1. One end of the third spring 37 is fixedly installed on one end of the positioning rod 36, and the other end of the third spring 37 is fixedly installed in the mounting block 38. The third spring 37 is used to provide the elastic force required for the positioning rod 36 to reset. The side wall of the mounting block 38 is fixedly installed on the side wall of the fixed rod 2. The mounting block 38 is used to provide support for the third spring 37 and the positioning rod 36.

[0060] During use, during the process of hoisting the current floor slab body 1 to a state parallel to the previous floor slab body 1, as the current floor slab body 1 continuously descends, it will drive the connecting block 39 to move downward synchronously, making the distance between the auxiliary block 3 on the previous floor slab body 1 and the driving plate 31 on the current floor slab body 1 closer and closer until the auxiliary block 3 abuts against the driving plate 31 and gives an upward extrusion force to the driving plate 31. Through the sliding fit between the driving plate 31 and the floor slab body 1, the driving plate 31 can only move linearly along the floor slab body 1. By the driving plate 31 squeezing the fixed sleeve 33 upward, the sliding groove 35 opened on the fixed sleeve 33 and the sliding column 34 are in sliding fit, so that the sliding column 34 limits the fixed sleeve 33, making the fixed sleeve 33 only able to slide along the sliding column 34 under the extrusion of the driving plate 31;

[0061] During the sliding process of the fixed sleeve 33 along the sliding column 34, the fixed sleeve 33 will first push the positioning rod 36 to move. Through the sliding fit between the positioning rod 36 and the mounting block 38, and at the same time, the third spring 37 provides elastic force to the positioning rod 36, causing the positioning rod 36 to first retract into the mounting block 38 and then pop out under the action of the third spring 37 and snap into the fixed sleeve 33. The two positioning rods 36 on the left and right of the mounting block 38 correspondingly snap into Figure 12 the two fixed sleeves 33 shown in Figure 12 , thereby assembling the two adjacent floor slabs 1 together;

[0062] Through the mutual limitation between the connecting block 39 and the assembly hole, the two adjacent floor slabs 1 cannot move back and forth. Through the mutual limitation between the positioning rod 36 and the fixed sleeve 33, the two adjacent floor slabs 1 cannot move left and right, thus being firmly assembled together.

[0063] The embodiment of the present invention also provides an assembly method for an energy-saving prefabricated floor slab for building thermal insulation, including the following steps:

[0064] S1. Install the connection component, the limit component, and the assembly component on the floor slab 1 in advance, fix the prefabricated floor slab 1 on the hoisting equipment, and start the hoisting equipment to hoist the floor slab 1 into the building;

[0065] S2. When the previous floor slab 1 is hoisted and the next floor slab 1 is to be hoisted, the sliding plate 29, the guiding plate 210, and the guiding block 213 in the connection components on the two floor slabs 1 cooperate with each other to limit the direction of the hoisting position of the next floor slab 1;

[0066] S3. When the next floor slab 1 is placed at the same height as the previous floor slab 1, the limit component restricts the deviation direction of the next floor slab 1;

[0067] S4. When the two floor slabs 1 are at the same height, the assembly component operates, and the positioning rod 36 and the fixed sleeve 33 cooperate with each other to assemble the two adjacent floor slabs 1 together;

[0068] S5. Continue the hoisting and assembly operations of the next floor slab 1.

[0069] The distance that the sliding plate 29 and the guiding plate 210 move under the drive of the guiding block 213 is between 0 - 5 cm.

[0070] To sum up, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages: The previous floor slab 1 provides guidance for the subsequent floor slabs 1 through the connection component, enabling quick and accurate positioning and alignment during hoisting, and reducing the time for manual adjustment;

[0071] Avoid repeated position adjustments due to the inclination or misalignment of the floor slab body 1, improving the installation speed;

[0072] Prevent the newly hoisted floor slab body 1 from tilting or sliding forward and backward, reducing the safety risks during high-altitude operations;

[0073] Ensure that the joints between each floor slab are uniform and flat, contributing to improving the overall building quality;

[0074] After the floor slabs are assembled, the connection components can be automatically unlocked, facilitating removal and reuse, saving material costs. The connection components are standardized and modular, easy to maintain, replace, and uniformly manage, shortening the construction period and indirectly reducing energy consumption and carbon emissions;

[0075] Effectively restrain the deflection of the floor slab body 1 in the left-right direction, ensure its accurate alignment, and avoid the situation where the floor slab body 1 is inclined when hoisted to the same horizontal plane as the previous floor slab body 1, resulting in misalignment and bringing difficulties to the subsequent assembly work;

[0076] Help achieve high-precision splicing and reduce subsequent processes such as caulking and patching;

[0077] Reduce the thermal bridge effect and air infiltration, improving the thermal insulation and energy-saving performance of the building;

[0078] Significantly improve the stability, safety, and assembly accuracy during the hoisting process of the prefabricated floor slab body 1;

[0079] After the floor slab body 1 is in place, the assembly action can be automatically completed without manual operation for fastening or alignment, saving a large amount of labor and time;

[0080] Form a stable structural system, improve the overall load-bearing capacity and seismic performance, ensure the same connection state for each floor slab body 1, reduce human errors, and achieve standardized and modular construction.
