[0046] The horizontal frame 31 usually has two layers. If the steel cage module to be prefabricated is too high, the length of the vertical pole 32 can be extended. Of course, in some other embodiments, there may be multiple layers of horizontal frames 31, that is, multiple layers of horizontal frames 31 are placed on the support rod 4. There may also be multiple layers of horizontal frames 31, some of which are placed on the support rod 4, and the remaining horizontal frames 31 are used as spares, that is, after the top horizontal frame 31 is hoisted away, the spare horizontal frames 31 are supplemented and placed on the support rod 4, so as to realize the rapid recycling of the prefabricated support device.

[0047] like Figure 4 As shown in the figure, the short cross bar 312, the horizontal bar 311 and the vertical bar 32 are all made of galvanized steel pipes. The short cross bar 312 and the horizontal bar 311 can be connected by a traditional scaffolding connection cross fastener. In this embodiment, in order to ensure the disassembly speed and the stability of the connection, the short cross bar 312 is connected to the horizontal bar 311 through a U-shaped connecting piece 313; the bottom opening of the U-shaped connecting piece 313 can accommodate the short cross bar 312 to pass through; the two free ends of the U-shaped connecting piece 313 are provided with a The through hole through which the horizontal rod 311 passes, the short cross rod 312 and the horizontal rod 311 are distributed up and down and cross each other; a fastening bolt 314 is provided at the bottom of the U-shaped connecting piece 313, and the fastening bolt 314 is threadedly connected to the U-shaped connecting piece 313. By tightening, the fastening bolt 314 can be extended into the end of the U-shaped connecting piece 313 and rest against the surface of the short cross rod 312, thereby pressing the short cross rod 312 against the surface of the horizontal rod 311 to realize the connection between the short cross rod 312 and the horizontal rod 311.

[0048] When the horizontal frame 31 has two layers, there are usually four vertical rods 32, which are respectively located at the two ends of the horizontal rod 311, and the vertical rods 32 are connected to the short cross rod 312 through cross fasteners.

When the limit member 43 is a spring pin, its fixed part is installed on the fixed through slot 41.

[0050] Example 2

[0051] like Figure 5 As shown, a construction method of a vertical wall reinforcement cage module is provided, comprising:

[0052] Step 1: Assemble the prefabricated support device and fix all the columns 2 on the ground in a straight line, and also fix the two positioning plates 1 on the ground in a front-to-back distribution.

[0053] Assemble the prefabricated support device, including:

[0054] Step 1.1: Select a number of unit section columns 21 according to the height of the steel cage module to be prefabricated, and install the unit section columns 21 as columns 2 in an end-to-end manner.

[0055] The unit section columns 21 are detachably connected by bolts; the number of the columns 2 can be determined according to the length of the steel cage module to be prefabricated.

[0056] Step 1.2: Install the support rod 4 on the column 2 , and place the horizontal rod 311 on the support rod 4 .

[0057] The support rod 4 is detachably mounted on the column 2 by means of screws.

[0058] Step 1.3: Connect the horizontal bars 311 on the front and rear sides of each layer through the short cross bars 312. During the connection process, adjust the connection position of the short cross bars 312 and the horizontal bars 311 according to the distance between the front and rear sides of the wall reinforcement cage module to be prefabricated.

[0059] Specifically, when the horizontal rod 311 is placed on the support rod 4, it has been penetrated by a plurality of U-shaped connectors 313, the short cross bar 312 is inserted into the opening between the U-shaped connector 313 and the horizontal rod 311, and the connection between the short cross bar 312 and the horizontal rod 311 is completed by tightening screws.

[0060] Step 1.4: Connect the horizontal racks 31 of adjacent layers into a whole through the vertical poles 32.

[0061] Step 2: Insert the bottom of the vertical reinforcement into the positioning through hole 11 of the positioning plate 1 according to the designed spacing, and tie the upper part of the vertical reinforcement to the horizontal rod 311 of each layer to realize the vertical reinforcement tying of the prefabricated steel cage module.

[0062] Tying the upper part of the vertical reinforcement to the horizontal rod 311 of each layer can ensure the verticality of the vertical reinforcement. The tying adopts 14# galvanized iron wire.

[0063] Step 3: Tie the horizontal reinforcement of the prefabricated reinforcement cage module.

[0064] Install horizontal steel bars from bottom to top in sequence according to standard spacing; each intersection of horizontal steel bars and vertical bars is bounded by binding wire, and no binding is allowed; the binding method adopts the figure-eight buckle method, and the direction of the figure-eight buckle is bounded by the middle vertical bar of the mesh, and is arranged symmetrically, and cannot be all in one direction; for walls with 4 layers of steel mesh, they should be tied in sequence from inside to outside (4L-1L), and the intersections of the 3 rows of horizontal bars and vertical bars at the top and bottom of the steel mesh should be tied and reinforced with 14# galvanized iron wire.

[0065] Step 4: The horizontal steel bars located at the front and rear sides of the column 2 are fixed by tensioning, and the tensioning and fixing of the wall embedded parts area and the area affected by the column 2 and the support rod 4 are suspended.

[0066] Step 5: hoist the preliminarily bound steel cage module and the uppermost horizontal frame 31 to the designated position. Before hoisting, separate the vertical pole 32 from the uppermost horizontal frame 31, and separate the support pole 4 and the lower horizontal frame 31 from the steel cage module.

[0067] The lifting point during hoisting is set at the top of the steel cage module, and the setting of the lifting point on the top of the steel cage module can refer to the existing technology.

[0068] When the lower horizontal frame 31 is separated from the steel cage module, loosen the fastening bolts 314 and pull the short cross bar 312 out of the U-shaped connecting piece 313; when the support rod 4 is a telescopic structure, when the support rod 4 is separated from the steel cage module, it is only necessary to retract the support rod 4.

[0069] Step 6: After the lifting is in place, the uppermost horizontal frame 31 inside the steel cage module is removed, and the reinforcement in the area affected by the columns 2 and the support rods 4 is fixed to complete the construction of the steel cage module.

[0070] When disassembling the topmost short cross bar 312 and horizontal bar 311 inside the steel cage module, loosen the fastening bolt 314 and pull the short cross bar 312 out of the U-shaped connecting piece 313.

[0071] Furthermore, in the present embodiment, when the vertical reinforcement and horizontal reinforcement of the prefabricated reinforcement cage module are being tied, the tying is performed simultaneously on the front and rear sides of the column 2 and maintained symmetric.

[0072] Furthermore, in the present embodiment, among the horizontal steel bars of the prefabricated steel cage module, the horizontal steel bars at the top and bottom layers are tied with the vertical bars of the steel cage module after the hoisting is completed.

[0073] Specifically, when tying horizontal steel bars, the horizontal steel bars at the top and bottom layers are tied on-site of the wall, that is, the prefabricated steel cage module is connected to the existing vertical bars in the wall through steel bar joints. After the connection is completed, the horizontal steel bars at the bottom layer of the steel cage module are tied to the vertical bars.

[0074] When in use, several layers of horizontal rods 311 and short cross rods 312 are configured as spares to achieve rapid recycling of the prefabricated support device. That is, after the top horizontal frame 31 and the steel cage module are hoisted away, the spare horizontal frame 31 is placed on the support rod 4, and the next prefabricated steel cage module can be made.

[0075] In order to ensure the overall stability of the steel cage, the main reinforcement is not disconnected when encountering the opening, but is cut after it is in place; however, additional reinforcement such as additional reinforcement bars at the opening, lateral structural reinforcement, U-shaped edge banding reinforcement, etc. need to be placed in advance during the prefabricated steel cage module stage. After the subsequent steel cage module is hoisted into place, the main reinforcement is cut according to the actual positioning on site, and the positioning of the additional reinforcement is adjusted.

[0076] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0077] The above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
