Description

Technical Field

[0001] The utility model relates to the technical field of floor slab installation, in particular to an installation device for a laminated dense-rib cavity floor slab. Background Art

[0002] Generally speaking, a one-way or two-way ribbed floor with a rib spacing of less than 1.5 meters is called a dense rib floor. Since the two-way dense rib floor bears the load in both directions, it has better mechanical performance. Compared with the reinforced concrete solid floor, the reinforced concrete cast-in-place hollow floor consumes less material and is lighter in weight. It is widely used in construction engineering.

[0003] In the prior art, the Chinese utility model with publication number CN216007473U discloses a new type of prefabricated dense-rib cavity floor slab, which includes cast-in-place dense ribs, a prefabricated bottom plate, side wall plates, and a prefabricated top plate. The prefabricated bottom plate, side wall plates, and prefabricated top plate enclose a cavity body, which is cast-in-place with the longitudinal and transverse steel reinforcement skeleton to form a cavity dense-rib floor slab; the prefabricated bottom plate and prefabricated top plate are provided with positioning protrusions on all sides; the side wall plates are made of renewable plastic, and the side wall plates are an integral structure formed by four single plates that can be folded and connected in sequence. This utility model replaces the traditional reinforced concrete prefabricated side wall plates with side wall plates made of renewable plastic. The side wall plates are a foldable integral structure, which is not only lightweight and easy to install, but also reduces transportation costs;

[0004] Although the cavity floor slabs in the existing technology reduce transportation costs, the installation method of prefabricated floor slabs in construction mostly uses a crane or a tower crane to lift the floor slabs to the installation location through a lifting rope, and then workers push the floor slabs to the installation location and pull out the lifting ropes. This method is relatively cumbersome and prone to safety accidents, which is not conducive to construction. Therefore, we need to propose a composite dense-rib cavity floor slab installation device.

[0024] See also Figure 1-4 The utility model provides a technical solution: a composite multi-rib cavity floor slab installation device, comprising:

[0025] A connecting assembly 100 for hook hanging, with multiple sets of bidirectional ring hanging bars 600 hung on the lower end of the connecting assembly 100, each set of bidirectional ring hanging bars 600 having a hanging assembly 200 hung on the lower end, the multiple sets of hanging assemblies 200 arranged in a rectangular array, the lower ends of the multiple sets of hanging assemblies 200 each clamping a floor slab body 400, and a limit assembly 300 provided at the lower end of the connecting assembly 100;

[0026] The lifting assembly 200 includes a fixed block 201, and two groups of guide columns 203 are fixedly connected to the lower surface of the fixed block 201. The lower ends of the two groups of guide columns 203 are fixedly connected to a right-angle carrier plate 204. The outer sides of the two groups of guide columns 203 are slidably connected to a pressure plate 206. The lower surface of the pressure plate 206 is bonded with an anti-slip pad 208. The upper surface of the pressure plate 206 is fixedly connected to a telescopic sleeve 209. The outer side of the telescopic sleeve 209 is provided with a compression spring 210.

The multiple groups of steel balls 205 contact the building support formwork, thereby facilitating the separation of the lifting assembly 200 and the floor slab body 400 and improving the disassembly efficiency of the lifting assembly 200.

[0028] A handle 207 is fixedly connected to one side of the pressure plate 206, and the outer surface of the handle 207 is provided with an anti-slip sleeve. The telescopic sleeve 209 is arranged between the two groups of guide columns 203. The handle 207 can be used to facilitate the rapid adjustment of the position of the pressure plate 206, thereby improving the efficiency of hoisting the floor cover body 400 and improving the installation efficiency of the floor cover body 400.

[0029] The limiting assembly 300 includes a fixed column 301 and a telescopic column 304. The lower surface of the fixed column 301 is provided with a storage hole 302 for the telescopic column 304 to slide and plug in. The lower ends of both sides of the telescopic column 304 are fixedly connected with a storage square tube 307. The opposite sides of the two groups of storage square tubes 307 are plugged with a limiting square column 308. The storage square tube 307 facilitates the storage of the limiting square column 308, so that different specifications of the floor cover body 400 can be used for lifting, thereby improving the scope of application.

[0030] Two sets of hanging ribs 500 for inserting the limiting square columns 308 are fixedly connected to the upper surface of the floor slab body 400.

The lower surfaces of the two groups of lower fixed plates 105 are fixedly connected with lower lifting ears 106 for hanging the upper ends of the bidirectional ring hanging bars 600. The lower lifting ears 106 on the two groups of lower fixed plates 105 facilitate lifting the lifting assembly 200 through the bidirectional ring hanging bars 600, thereby improving the stability of the lifting of the floor slab body 400.

[0034] When in use, the steel cable eye 104 of the connecting assembly 100 is hung on the hook of a tower crane or a crane so that the entire device can be moved to the area where the floor panels are stacked. The construction personnel first pull out the limiting square column 308 and insert it into the hanging rib 500 on the surface of the floor panel body 400 to facilitate rapid adjustment of the lifting assembly 200. After the lifting handle 207 makes the right-angle carrier plate 204 contact the floor panel body 400, the anti-slip pad 208 on the pressing plate 206 is made to fit the surface of the floor panel body 400 under the action of the compression spring 210. Repeat the process of clamping four sets of lifting assemblies 200 at the four corners of the floor panel body 400, thereby achieving rapid clamping of the floor panel body 400. Or the crane raises the hook to facilitate the rapid movement of the floor slab body 400 and improve the stability during the movement. After moving to the self-propelled position, the steel ball 205 of the lifting component 200 contacts the building template and maintains a certain distance between the floor slab and the template. The construction worker quickly toggles the handle 207 to separate the lifting component 200 from the floor slab body 400, and the hook drops again to place the floor slab body 400 in the designated template area, thereby realizing the rapid installation of the floor slab body 400. After the installation is completed, the limiting square column 308 is stored in the storage square tube 307 to facilitate the lifting of the next group of floor slab bodies 400. The operation is simple and fast, which improves the safety of the workers.
