Description

Technical Field

[0001] The present invention relates to the field of hoisting full prefabricated wall panels, and more specifically, to a full prefabricated wall panel nail-free and pre-embedded component and a fixing and adjusting method. Background Art

[0002] At present, in fully prefabricated construction projects, after the prefabricated wall panels are hoisted into place, before permanent connections are formed, it is necessary to install inclined supports for reliable temporary fixation, and use the inclined supports to adjust the angle to ensure the verticality of the prefabricated wall panels. This is a very important means.

[0003] At present, there are basically two methods for reliable temporary fixation of full prefabricated wall panels and inclined supports: a. directly use cement self-tapping screws to nail the inclined supports to the full prefabricated wall panels; b. reserve threaded sleeves on the full prefabricated wall panels and fix the full prefabricated wall panels and inclined supports with bolts; However, both of the above methods have very obvious technical defects: a. When using cement self-tapping screws, since the on-site operators cannot identify the position and direction of the pre-buried water and electricity pipes in the fully prefabricated wall, cement self-tapping screws often penetrate the pre-buried water and electricity pipes, which require grooving and repair in the later decoration; b. Embedding threaded sleeves in the fully prefabricated wall panels will complicate the production process, especially when the wall panel surface is roughened, it will interfere with the cantilevered embedded sleeves, affecting the factory production efficiency; c. Both of the above methods have the problem of holes left after the disassembly of the inclined support that need to be repaired; d. In more and more actual cases, the fully prefabricated wall panels will be preliminarily decorated or renovated during factory production to reduce on-site construction time. The above two methods will destroy the preliminary decoration or fine decoration pre-constructed in the factory; e. In the above two methods, during the actual on-site operation, the operators need to go up and down the ladder or ladder to operate, which poses a construction safety risk; f. Both of the above methods have the problem of repeated use of cement self-tapping screws or embedded sleeves. Summary of the invention

[0004] In order to solve the above problems, this patent proposes a fully prefabricated wall panel that does not require nails or pre-embedded components and a fixing and adjustment method, which can quickly make the fully prefabricated wall panels temporarily fixed and the angle adjusted without the need for pre-embedded components, self-tapping screws, or repairs.

[0019] The following further describes the present invention in detail with reference to the accompanying drawings and embodiments, and the specific implementation process is as follows: Embodiment

[0020] As Figures 1 - 9 shown, the present invention provides a nail - free and embedded - free assembly for fully precast wall panel. In this embodiment, the structure to be connected is a steel structure or a concrete structure. Among them, the concrete structure can be a cast - in - place or precast floor slab. It is characterized by including: a hanging bracket assembly and a diagonal bracing member; The hanging bracket assembly is of a U - shaped structure and is hung upside down at the upper end of the fully precast wall panel; one end of the diagonal bracing member is rotatably connected to the hanging bracket assembly, and the other end of the diagonal bracing assembly is fixed to the structure to be connected, so as to realize the temporary fixation of the fully precast wall panel and the structure to be connected.

[0021] In a preferred embodiment of the present application, it further includes a pressure plate assembly, which is arranged on the hanging bracket assembly. The pressure plate assembly is set to be adjustable in distance from the fully precast wall panel and is used to press against the fully precast wall panel.

[0022] In a preferred embodiment of the present application, the hanging bracket assembly includes a hanging bracket cross bar 51, a first hanging bracket vertical bar 52, a second hanging bracket vertical bar 53, and a hanging bracket diagonal bar 54; both ends of the hanging bracket cross bar are perpendicularly connected to the first hanging bracket vertical bar and the second hanging bracket vertical bar respectively. The length of the first hanging bracket vertical bar is longer than that of the second hanging bracket vertical bar. The bottom of the second hanging bracket vertical bar is connected to the hanging bracket diagonal bar. The arrangement of the hanging bracket diagonal bar makes the entrance of the hanging bracket assembly larger than the distance between the first hanging bracket vertical bar and the second hanging bracket vertical bar. The hanging bracket diagonal bar serves as a guiding component to facilitate the hanging bracket assembly to be hung upside down above the fully precast wall panel.

[0023] In a preferred embodiment of the present application, the diagonal bracing member includes an upper connecting rod, a middle adjusting rod, and a tail connecting rod assembly; The middle adjusting rod has internal threads, and the upper connecting rod 71 and the tail connecting rod assembly are respectively threadedly connected to both ends of the middle adjusting rod 72; The tail connecting rod assembly includes a tail connecting rod 73 and a mounting seat. The mounting seat 74 is hinged to the bottom of the tail connecting rod, and the mounting seat is fixed to the structure to be connected through self-tapping screws / expansion bolts 75.

[0024] During specific implementation, the operator rotates the middle adjusting rod through the adjusting handle to achieve the purpose of adjusting the length of the diagonal bracing. Figure 9 As shown: the tail connecting rod assembly, where the mounting seat is fixed on the floor slab. At this time, a stable triangle is formed among the fully precast wall panel, the components of the present application, and the cast-in-place or precast floor slab.

[0025] In a preferred embodiment of the present application, the diagonal bracing member is connected to the hanging bracket assembly through a rotating component; The rotating component 4 includes a base 41, a first bearing 42, and a first rotating shaft 43; the first rotating shaft is installed on the base through the first bearing. The end of the first rotating shaft is fixed to the base through a gasket 46 and a first bolt 47. The other end of the first rotating shaft is hinged to the upper connecting rod, and the base is fixed to the first hanging bracket vertical bar. Figure 7 As shown: the base is welded and fixed to the first hanging bracket vertical bar. The other end of the first rotating shaft is connected to the upper connecting rod through a pin 44, and an anti-detachment pin 45 is provided to prevent the pin from accidentally falling off during vibration, impact, or long-term use.

[0026] In the above embodiment, the rotating component mainly realizes the adjustment of the upper connecting rod in 4 directions through the combination of the first bearing, the first rotating shaft, and the pin. Coupled with the telescopic adjustment of the middle adjusting rod, the adjustment in 6 directions can be achieved.

[0027] In a preferred embodiment of the present application, Figure 5As shown: the assembly form of the hanging rack assembly and the pressure plate assembly. The pressure plate assembly 6 includes a pressure plate 61, a second bearing 62, a second rotating shaft 63, high-strength bolts 64 and high-strength nuts 65. The high-strength bolts are screwed to the lower part of the first vertical rod of the hanging rack and are fastened by high-strength nuts. The other end of the high-strength bolts is connected to the second rotating shaft. The second rotating shaft is connected to the pressure plate through the second bearing. The pressure plate is of a disc-shaped structure, and its plate surface presses against the surface of the fully precast wall panel for positioning and fixing the fully precast wall panel. By rotating the high-strength bolts, the thickness of the wall panel that needs to be temporarily fixed can be adjusted.

[0028] In a preferred embodiment of the present application, an adjusting handle 76 is provided on the middle adjusting rod to facilitate screwing the middle adjusting rod and adjusting the overall length of the diagonal bracing member.

[0029] As Figure 1 shown: After the fully precast wall panel nail-free and embedded-free assembly is completed, a universal adjustable diagonal bracing structure is formed. When the fully precast wall panel is hoisted, diagonal bracing is required for temporary fixing. During specific implementation, the operator only needs to stand on the floor slab and directly hang the hanging rack on the top of the wall panel, and rotate Figure 3 the pressure plate assembly with an electric wrench, so that the entire diagonal bracing forms a reliable connection with the wall panel. Embodiment

[0030] A fixing and adjusting method using a fully precast wall panel nail-free and embedded-free assembly includes the following steps: 1) After the fully precast wall panel 1 is hoisted and positioned, the operator stands on the structure to be connected 2 (in this embodiment, it is the floor slab) and directly hangs the hanging rack assembly on the top of one side of the fully precast wall panel. 2) Use an electric wrench to rotate the pressure plate assembly. The mutual acting force between the hanging rack assembly and the pressure plate assembly presses the top of the wall panel, so that the entire diagonal bracing forms a reliable connection with the wall panel. 3) Hold the middle adjusting rod and adjust the installation angle, and use self-tapping screws / expansion bolts to fix the tail connecting rod assembly on the structure to be connected. 4) Repeat the operations in steps 1) to 3). Install a fully precast wall panel nail-free and embedded-free assembly 3 at the other end of the wall panel as well. If the wall panel exceeds 6 meters, install a fully precast wall panel nail-free and embedded-free assembly at the middle position of the wall panel as well. 5) Rotate the middle adjusting rod to adjust the distance between the upper connecting rod and the tail connecting rod assembly to achieve the purpose of adjusting the verticality of the fully precast wall panel. 6) Remove the hook. The temporary fixing and adjustment of the fully precast wall panel are completed, and continue with the installation of the next fully precast wall panel.

[0031] The present application proposes a method for fixing and adjusting fully precast wall panels without nails and embedded parts. Compared with traditional inclined supports, the top of the wall panel is pressed tightly through the interaction between the hanging bracket assembly and the pressure plate assembly, eliminating the embedded sleeves or cement self-tapping screws in the wall panel; through the combined action of the rotating assembly and the tail connecting rod assembly, the entire inclined support can be installed on the floor at any angle, without the need to plan the layout of inclined supports for the entire building to avoid interference between inclined supports.

[0032] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and embodiments. It can be fully applicable to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the embodiments shown and described herein.
