Description

[0001] This application is a divisional application. The original application number was CN202410467305.7, the application date was April 18, 2024, and the invention title was "A Composite Floor Slab, Composite Floor Slab Lifting Construction Equipment and Method Thereof". Technical Field

[0002] This invention relates to the field of composite floor slabs, specifically a construction method for composite floor slab hoisting equipment. Background Technology

[0003] With the rapid development of the construction industry, the requirements for the quality and performance of buildings are increasing. In particular, in high-rise buildings and large public buildings, there are more stringent requirements for the load-bearing capacity and seismic performance of floor slabs. Traditional floor slab construction methods, such as integral casting or hollow slab installation, have problems such as long construction cycle, poor seismic performance and material waste, which can hardly meet the needs of modern buildings.

[0004] However, the construction technology and equipment for composite floor slabs are also key factors affecting their application. Traditional hoisting construction equipment and methods often suffer from problems such as complex operation, low precision, and poor safety, making it difficult to guarantee the installation quality and construction efficiency of composite floor slabs. Therefore, researching and developing new hoisting construction equipment and methods for composite floor slabs is of great significance for improving the construction quality and efficiency of composite floor slabs and promoting their widespread application in the construction industry. Summary of the Invention

[0005] This invention provides a construction method for a composite floor slab hoisting construction device, which overcomes the shortcomings described in the background art.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A composite floor slab includes a floor slab body composed of a first slab and a second slab. The upper edge of the first slab is provided with a downwardly recessed step edge, and the second slab is installed on the step edge. The side of the first slab away from the step edge is provided with a protruding plate. When the second slab is installed on the step edge, a first positioning groove is formed between the second slab and the step edge. When the two floor slab bodies are joined together, the protruding plate on the side of one floor slab body is embedded in the first positioning groove on the side of the other floor slab body.

[0008] The step edge is provided with a positioning hole, which is penetrated downward through a first bolt hole. The second plate has a corresponding protrusion, and the axis of the protrusion is also provided with a second bolt hole that penetrates both the upper and lower ends. When the second plate is installed on the step edge, the protrusion is embedded in the positioning hole, and the protrusion and the first bolt hole are coaxially arranged.

[0009] The first plate has symmetrically provided embedding grooves at the middle of its upper end. The embedding grooves extend downward at an incline, and a reinforcing rib protruding outward is provided at the upper edge of the embedding groove. The lower end of the first plate has a corresponding second positioning groove. When the upper and lower floor slabs are stacked, the reinforcing rib on the surface of the lower floor slab is embedded in the second positioning groove of the upper floor slab. All adjacent second bolt holes and first bolt holes are coaxially arranged.

[0010] A preferred technical solution includes a drive assembly and a clamping device mounted on a walking device. The drive assembly includes a first robotic arm, a second robotic arm, and a drive cylinder. The second robotic arm is fixed by the first robotic arm, and the drive cylinder is mounted on the side of the second robotic arm. The lower end of the second robotic arm and the lower end of the drive cylinder are respectively movably connected to the upper left and right sides of the clamping device, and the lower left and right sides of the clamping device are respectively embedded in two embedded slots of the floor slab body.

[0011] A composite floor slab hoisting construction device, the clamping device includes a clamping assembly, a support plate, and a rotary drive cylinder. The rotary drive cylinder is connected to the lower end of the support plate. The support plate drives the clamping assembly to rotate through the rotary drive cylinder. The clamping assembly is symmetrically provided with an embedded plate, a hydraulic push rod, and a fixing plate. Linear rails are respectively provided on both sides of the inner end of the clamping assembly. Corresponding sliding grooves are provided on the side of the embedded plate. The linear rails are embedded in the sliding grooves. Both embedded plates are driven to slide on the linear rails by the hydraulic push rods. The hydraulic push rods are fixed to the inner side of the clamping assembly by the fixing plate.

[0012] The embedded plate gradually slopes outward from the middle to the lower end. When the floor slab body is clamped, the embedded plate is embedded in the embedded groove, and the embedded plate abuts against the edge of the reinforcing rib.

[0013] A preferred technical solution: Two cables are provided on both sides of the clamping assembly, and each cable is connected to a hook plate at its end. The hook plate has an L-shaped structure and abuts against the lower edge of the floor slab body when clamping the floor slab body.

[0014] Based on the construction method of the composite floor slab hoisting equipment described above, the construction method includes the following specific steps:

[0015] S1: First, move all the floor slabs to the construction site as a whole, and wait for installation and assembly;

[0016] S2: The floor slab is then moved to the top of the building structure by the drive unit and clamping equipment installed on the walking device for construction.

[0017] S3: Construct a protruding or recessed structure at the corresponding position of the building structure, the protruding plate, and the first positioning groove, or directly fix the floor slab body through mortise and tenon joints.

[0018] S4: According to the required number of stacked units, move the uninstalled floor slabs to the floor slabs already installed on the building joint, and fill the space between the two floor slabs with an adhesive medium such as concrete or adhesive, so that the adhesive medium fully fills the embedded groove, the second bolt hole and the first bolt hole. Finally, stack and fix the two floor slabs by rivets passing through all the second bolt holes and the first bolt holes.

[0019] Compared with existing technologies, this technical solution has the following advantages:

[0020] In this invention, the floor slabs are all pre-formed. When the composite floor slabs are installed onto the building structure, they can be simultaneously snapped or spliced ​​onto the building structure through the protruding plates on both sides of the floor slabs or the first positioning groove. To achieve the above two connection methods, it is necessary to build or form corresponding structures on the building structure to increase the connection relationship. When installing the composite floor slabs in this invention, the number installed varies with the thickness of the building to be built. When multiple floor slabs are stacked, they can be stacked upwards in sequence, and the adjacent reinforcing ribs can be embedded in the second positioning groove to form a fixation between the upper and lower floor slabs. At the same time, in order to further fix multiple floor slabs, concrete or adhesive can be filled between the two floor slabs. By attaching the adhesive to the surface between the two floor slabs and filling the embedded groove, a fixation is formed.

[0021] In this invention, when multiple floor slabs are stacked together, the protrusion of the upper floor slab can be inserted into the positioning hole for positioning. Therefore, the positioning hole can be understood as a structure used in conjunction with the protrusion. During the construction process, it mainly plays the role of guiding and limiting. When the second plate is installed on the edge of the step, the construction personnel can fix the single floor slab by installing bolts, so that the bolts pass through the second bolt hole and the first bolt hole. When fixing multiple floor slabs, it is only necessary to install a rod-shaped fastener such as a rivet or bolt of sufficient length to realize the installation of multiple floor slabs.

[0022] In this invention, the embedding groove is set at an angle to facilitate the insertion of the embedding plate. Driven by the hydraulic push rods, the embedding plates on both sides move to the sides, and guided by the contour of the embedding groove, the entire floor slab body is lifted up. By expanding outward and engaging with the embedding groove, the floor slab body is clamped and fixed. Therefore, it can be understood that when clamping the floor slab body, the clamping device in this invention only needs to insert the embedding plates on both sides into the embedding groove on the upper side of the first plate body at the same time, and extend the output shafts of the hydraulic push rods on both sides outward at the same time, and the floor slab body will automatically complete the positioning without human operation and guidance, thereby further accelerating the construction efficiency of the construction personnel.

[0037] like Figures 1-3As shown, this invention proposes a composite floor slab, comprising a floor slab body 3 composed of a first plate 31 and a second plate 32. The upper edge of the first plate 31 has a downwardly recessed step edge, and the second plate 32 is installed on the step edge. A protruding plate 314 is provided on the side of the first plate 31 away from the step edge. When the second plate 32 is installed on the step edge, a first positioning groove 315 is formed between the second plate 32 and the step edge. When the two floor slab bodies 3 are joined together, the protruding plate 314 on the side of one floor slab body 3 is embedded into the first positioning groove 315 on the side of the other floor slab body 3. Since the composite floor slab of this invention is mainly used for constructing quick-build building structures, the floor slab bodies 3 in this invention are all pre-formed. When the composite floor slab is installed onto the building structure, it can... The building structure can be simultaneously fastened or spliced ​​by the protruding plates 314 or the first positioning groove 315 on both sides of the floor slab body 3. To achieve the above two connection methods, it is necessary to build or form a corresponding structure on the building structure to increase the connection relationship. When installing the composite floor slab in this invention, the number installed varies with the thickness of the building to be built. When multiple floor slab bodies 3 are stacked, they can be stacked upwards in sequence, and the adjacent reinforcing ribs 312 can be embedded in the second positioning groove 316 to form a fixation between the upper and lower floor slab bodies 3. At the same time, in order to further fix multiple floor slab bodies 3, concrete or adhesive can be filled between two floor slab bodies 3. The fixation is formed by attaching the adhesive medium to the surface between the two floor slab bodies 3 and filling the embedding groove 311.

[0038] The step edge is provided with a positioning hole 313, which passes downward through a first bolt hole 3131. The second plate 32 has a corresponding protrusion 321, and the axis of the protrusion 321 is also provided with a second bolt hole 3211 passing through both the upper and lower ends. When the second plate 32 is installed on the step edge, the protrusion 321 is embedded in the positioning hole 313, and the protrusion 321 and the first bolt hole 3131 are coaxially arranged. Based on this, when multiple floor slab bodies 3 are stacked vertically, the protrusion 321 of the upper floor slab body 3 can be inserted. Positioning is performed in the positioning hole 313. Therefore, the positioning hole 313 can be understood as a structure used in conjunction with the protrusion 321. During the construction process, it mainly plays the role of guiding and limiting. When the second plate 32 is installed on the edge of the step, the construction personnel can install bolts again, so that the bolts pass through the second bolt hole 3211 and the first bolt hole 3131 to form a single floor slab body 3. When fixing multiple floor slab bodies 3, it is only necessary to install a rod-shaped fastener such as a rivet or bolt of sufficient length to realize the installation of multiple floor slab bodies 3.

[0039] Based on the above, this invention also proposes a composite floor slab hoisting construction device, including a drive assembly 1 and a clamping device 2 mounted on a walking device. The drive assembly 1 includes a first robotic arm 11, a second robotic arm 12, and a drive cylinder 13. The second robotic arm 12 is fixed by the first robotic arm 11, and the drive cylinder 13 is mounted on the side of the second robotic arm 12. The lower ends of the second robotic arm 12 and the lower ends of the drive cylinder 13 are respectively movably connected to the upper left and right sides of the clamping device 2. The lower left and right sides of the clamping device 2 are respectively embedded in two embedding slots 311 of the floor slab body 3. The clamping device 2 includes a clamping assembly 21, a support plate 22, and a rotation drive. The hydraulic cylinder 23 is connected to the lower end of the support plate 22. The support plate 22 drives the clamping assembly 21 to rotate through the hydraulic cylinder 23. The clamping assembly 21 is symmetrically provided with an embedded plate 212, a hydraulic push rod 213, and a fixing plate 214. The inner ends of the clamping assembly 21 are respectively provided with linear rails 215. The side of the embedded plate 212 is provided with a corresponding sliding groove 2121. The linear rails 215 are embedded in the sliding grooves 2121. Both embedded plates 212 are driven to slide on the linear rails 215 by the hydraulic push rod 213. The hydraulic push rod 213 is fixed to the inner side of the clamping assembly 21 by the fixing plate 214. The middle and lower ends of the embedded plate 212 gradually tilt outward.

[0040] Meanwhile, in this invention, the upper middle part of the first plate 31 is symmetrically provided with an embedding groove 311. The embedding groove 311 extends downward at an inclination, and the upper edge of the embedding groove 311 is provided with an outwardly protruding reinforcing rib 312. The lower end of the first plate 31 is provided with a corresponding second positioning groove 316. When the upper and lower floor slab bodies 3 are stacked, the reinforcing rib 312 on the surface of the lower floor slab body 3 is embedded in the second positioning groove 316 of the upper floor slab body 3. All the adjacent second bolt holes 3211 and the first bolt holes 3131 are coaxially arranged. When clamping the floor slab body 3, the embedding plate 212 is embedded in the embedding groove 311, and the embedding plate 212 abuts against the edge of the reinforcing rib 312.

[0041] It is necessary to explain that the inclined shape of the embedding groove 311 in this invention is to facilitate the insertion of the embedding plate 212. Under the drive of each hydraulic push rod 213, the embedding plates 212 on both sides move to the sides. As the contour of the embedding groove 311 guides, the entire floor slab body 3 is lifted up. When the two embedding plates 212 expand outward and engage with the embedding groove 311, the floor slab body 3 is clamped and fixed. Therefore, it can be understood that when the clamping device 2 in this invention clamps the floor slab body 3, as long as the embedding plates 212 on both sides are simultaneously inserted into the embedding groove 311 on the upper side of the first plate 31 and the output shafts of the hydraulic push rods 213 on both sides extend outward, the floor slab body 3 will automatically complete the positioning without the need for manual operation and guidance, thereby further accelerating the construction efficiency of the construction personnel.

[0042] Furthermore, two cables 211 are respectively provided on both sides of the clamping component 21, and each cable 211 is connected to a hook plate 2111 at its end. The hook plate 2111 has an L-shaped structure. When clamping the floor slab body 3, the hook plate 2111 rests against the lower edge of the floor slab body 3. The hook plate 2111 is provided to facilitate the clamping component 21 to grip the floor slab body 3, and plays a protective role to prevent the floor slab body 3 from falling off when it is not successfully clamped. The hook plate 2111 can effectively prevent this situation from happening.

[0043] It is necessary to explain that the support plate 22 is provided with a first connecting block 221 and a second connecting block 222. The first connecting block 221 is oscillatingly connected to the second robotic arm 12, and the second connecting block 222 is oscillatingly connected to the drive cylinder 13.

[0044] Based on the aforementioned composite floor slabs and composite floor slab hoisting equipment, this invention also proposes a construction method for composite floor slab hoisting equipment, the construction method comprising the following specific steps:

[0045] S1: First, move all the floor slabs 3 as a whole to the construction site, and wait for installation and assembly;

[0046] S2: The floor slab body 3 is then moved to the top of the building structure by the drive unit 1 and clamping device 2 installed on the walking device for construction.

[0047] S3: Construct a protruding or recessed structure at the corresponding position of the building structure and the protruding plate 314 and the first positioning groove 315, or directly fix the floor slab body 3 through mortise and tenon joints.

[0048] S4: According to the required number of stacked units, the uninstalled floor slab bodies 3 are transported to the floor slab bodies 3 that have been installed above the building joint, and the space between the two floor slab bodies 3 is filled with adhesive medium such as concrete or adhesive, so that the adhesive medium fully fills the embedded groove 311, the second bolt hole 3211 and the first bolt hole 3131. Finally, the two floor slab bodies 3 are stacked and fixed by rivets passing through all the second bolt holes 3211 and the first bolt holes 3131.

[0049] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
