[0002] Composite floor slabs are assembled integral floor slabs made of prefabricated panels and cast-in-place reinforced concrete layers. Composite floor slabs have good integrity, flat upper and lower surfaces, and are easy to decorate the finishing layer. They are suitable for high-rise buildings and large-span buildings that require high overall rigidity. At the same time, because composite floor slabs are prefabricated, the construction period is greatly shortened, and they are widely used in engineering.

[0041] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the embodiment of the present application. It is worth noting that the embodiments described in the drawings are only part of the embodiments of the present application, not all of the embodiments. That is, the embodiments described by the drawings are exemplary and are intended to be used to explain the present application, and cannot be understood as limiting the present application.

[0042] The following will be combined Figure 1-Figure 5 The composite floor support device 100 provided in an embodiment of the present application is described.

[0043] The present application embodiment provides a composite floor support device 100, such as Figure 1-Figure 5 As shown, it includes side plates 110 , transverse support plates 121 , longitudinal support plates 122 , lifting plates 130 , guide members 131 , composite floor support plates 140 , driving devices 150 and locking members 132 .

[0044] The side plate 110 is used for being detachably connected to the embedded component system 300 , and the transverse support plate 121 extends in the horizontal direction and is vertically fixed on the side plate 110 .

[0045] Two longitudinal support plates 122 are arranged at intervals. Both of the two longitudinal support plates 122 extend in the vertical direction and are vertically fixed to the upper side of the transverse support plate 121 . Both of the two longitudinal support plates 122 are fixedly connected to the side plate 110 .

[0046] The lifting plate 130 is located on the upper side of the two longitudinal support plates 122. A guide member 131 is connected between the lifting plate 130 and at least two of the two longitudinal support plates 122 and the side plates 110. A composite floor support plate 140 for supporting the composite floor is arranged on the upper side of the lifting plate 130.

[0047] The driving device 150 is used to be arranged on the transverse support plate 121 between the two longitudinal support plates 122, and the output end of the driving device 150 is used to drive the lifting plate 130 to move upward and downward in the vertical direction away from or toward the transverse support plate 121 under the guidance of the guide member 131. The transverse support plate 121 is provided with a locking member 132 for locking the lifting position of the lifting plate 130.

[0048] The side panel 110 can be installed on the embedded component system 300 of the side wall 400 by means of a locking nut, and the side of the side panel 110 away from the transverse support plate 121 is in contact with the side wall 400 or the cement cast wood formwork 200 on the side of the side wall 400. After installation, the top of the side panel 110 is lower than the elevation of the prefabricated panel 500.

[0049] The transverse support plate 121 is fixed at the middle of the height of the side plate 110. The lifting plate 130 spans the top between the two longitudinal support plates 122. The top area of ​​the composite floor support plate 140 can be slightly smaller than the top area of ​​the lifting plate 130, and its surface close to the side plate 110 can be flush with the surface of the side plate 110 away from the transverse support plate 121.

[0050] When the composite floor support device 100 of the embodiment of the present application is used, first, the main body of the composite floor support device 100 is installed below the position where the prefabricated panel 500 is to be installed, so that the side panel 110 is connected to the embedded part system 300 of the side wall 400, and the side panel 110 is arranged parallel to the side wall 400. Secondly, the prefabricated panel 500 is hoisted and placed on the composite floor support plate 140 on the upper side of the lifting plate 130. After that, the driving device 150 is placed on the transverse supporting plate 121 between the two longitudinal supporting plates 122, and the output end of the driving device 150 moves upward and abuts against the lower surface of the lifting plate 130. Then, the height of the prefabricated panel 500 is adjusted according to the actual situation, so that the output end of the driving device 150 moves up and down, and the lifting plate 130 moves up and down in the vertical direction under the guidance of the guide member 131. After the adjustment is completed, the position of the lifting plate 130 is locked by the locking member 132, and the driving device 150 is unloaded and taken out. At this point, the positioning of the elevation position of the composite floor is completed. Then, subsequent pouring work of the composite floor is carried out. After the poured concrete of the composite floor reaches a certain strength, the connection between the side plate 110 and the embedded part system 300 is removed, and the composite floor support device 100 is stored for next use.

[0051] The composite floor support device 100 provided in the embodiment of the present application can adjust the height of the composite floor, has a reasonable structure, is simple to operate, is easy to disassemble, and can be reused, thereby improving construction efficiency, reducing costs, and improving the overall aesthetics after construction.

[0052] In one possible implementation, Figure 2 Combined with Figure 1 and Figure 3 As shown, the lifting plate 130 is connected to the composite floor support plate 140 through a universal ball 133.

[0053] In this way, the lifting plate 130 and the composite floor support plate 140 are universally connected, and the composite floor support plate 140 can be adaptively leveled in the horizontal direction under the action of the universal ball 133 and the gravity of the composite floor.

[0054] In one possible implementation, Figure 1 and Figure 3 As shown, a rubber pad 141 for buffering is provided on the upper side of the composite floor support plate 140 .

[0055] In this way, the rubber pad 141 can have a cushioning effect on the composite floor, thereby preventing the gravity impact of the composite floor from affecting the stability of the entire device.

[0056] In one possible implementation, Figure 1-Figure 4 As shown, the top of the longitudinal support plate 122 is flush with the top of the side plate 110 .

[0057] In this way, the bottom surface of the lifting plate 130 is flush with the top of the side plate 110, which makes it easy to operate the up and down movement of the lifting plate 130 with the top of the side plate 110 as a reference, and to adjust the height of the composite floor, which is convenient to operate.

[0058] In one possible implementation, Figure 1 and Figure 3 As shown, guide members 131 are provided between the two longitudinal support plates 122 and the side plates 110 and the lifting plate 130 .

[0059] In this way, the lifting and lowering movement of the lifting plate 130 in the vertical direction is guided by the three groups of guide members 131, thereby improving the accuracy of adjusting the lifting height.

[0060] In one possible implementation, Figure 1 and Figure 3 As shown, the guide member 131 includes a guide rod extending in the vertical direction, the upper end of the guide rod is fixedly connected to the lifting plate 130, the lower end of the guide rod is a free end, and the surfaces of the side plate 110 and the longitudinal support plate 122 are tightly fitted with the side surfaces of the corresponding guide rod.

[0061] Alternatively, the guide member 131 includes a guide rod and a guide rail extending in the vertical direction, the upper end of the guide rod is fixedly connected to the lifting plate 130, the lower end of the guide rod is a free end, and guide rails are arranged on the surfaces of the side plate 110 and the longitudinal support plate 122 at positions corresponding to the guide rods, and the guide rods are slidably connected in the guide rails.

[0062] In this way, the guiding function of the guide member 131 on the lifting plate 130 can be achieved through the cooperation between the guide rod and the surface or the guide rod and the guide rail, and the appropriate structural form of the guide member 131 can be selected according to actual conditions.

[0063] In one possible implementation, Figure 1 , Figure 3-Figure 5 As shown, a plurality of connection holes 111 for connecting the embedded component system 300 are provided on the side plate 110 , and each connection hole 111 is in the shape of a long strip extending in the horizontal direction.

[0064] The embedded part system 300 may include a plurality of steel bars that are inserted into the connection seat, the inner ends of the connection seat and the steel bars are embedded in the side wall 400, and the outer ends of the steel bars extend out of the side wall 400 toward the side of the prefabricated panel 500 and are processed with external threads. The connection holes 111 on the side panel 110 correspond to the number and position of the steel bars. The cement casting tree formwork 200 is provided with long strip formwork connection holes corresponding to the number and position of the steel bars. The long strip connection holes 111 can improve the adaptability of the side panel 110 to the change in the spacing between the steel bars when connecting.

[0065] When in use, the simulated cement-casting wood formwork 200 and the side panel 110 are sequentially inserted into the protruding ends of the steel bars, and the locking nut is screwed onto the protruding ends of the steel bars from one side of the side panel 110, so that the side panel 110 and the cement-casting wood formwork 200 fit closely to the side wall 400, thereby fixing the composite floor support device 100 on the embedded part system 300 at the side wall 400.

[0066] In one possible implementation, Figure 1 and Figure 4 As shown, the driving device 150 includes a hydraulic jack, which is placed on the transverse support plate 121 , and the output end of the hydraulic jack abuts against the lower surface of the lifting plate 130 .

[0067] In this way, the lifting plate 130 can be adjusted to any height by hydraulic drive, which is convenient for operation.

[0068] In a feasible embodiment, the locking member 132 includes a plurality of high-strength bolts, each of which is passed through a preset bolt hole in the transverse support plate 121, the head end of each high-strength bolt is located on the lower side of the transverse support plate 121, the tail end of each high-strength bolt supports the lower surface of the lifting plate 130, and a locking nut is arranged between the head end of each high-strength bolt and the transverse support plate 121.

[0069] The lifting plate 130 may be supported by four high-strength bolts, and the position of the lifting plate 130 may be locked by a locking nut, so that the lifting plate 130 remains stable at the elevation position.

[0070] In one possible implementation, Figure 1 and Figure 3 As shown, the composite floor support device 100 also includes two spaced-apart ribs 123 , both of which extend in the vertical direction and are vertically fixed to the lower side of the transverse support plate 121 , and both of which are fixedly connected to the side plate 110 .

[0071] Among them, the two rib plates 123 can be symmetrically arranged in a one-to-one correspondence with the two longitudinal support plates 122 on the upper side of the transverse support plate 121, and the rib plates 123 are used to improve the support of the lifting plate 130, thereby improving the support capacity of the composite floor.
