[0002] Frame columns are core load-bearing components of civil buildings such as teaching complexes, and their structural stability and molding precision directly affect the overall safety performance of the building. Formwork shells, as molding molds in the concrete pouring process of frame columns, are mainly used to limit the cross-sectional dimensions of the columns and ensure the concrete pouring shape; they are a key auxiliary component in frame column construction. In building construction, formwork shells need to be assembled according to the design specifications of the frame columns to form a closed cavity before concrete pouring. Traditionally, formwork shells are mostly assembled on-site by cutting and manually splicing to adapt to the construction needs of frame columns in different projects.

[0003] However, the aforementioned prefabricated modular frame shell column rapid positioning and splicing device has a complicated construction process. The assembly of the shell relies on repeated manual adjustments and positioning, which is time-consuming and redundant. It cannot meet the schedule requirements for simultaneous construction of multiple sub-projects, indirectly affecting the construction efficiency and forming quality of the frame columns.

[0021] Example 1 The prefabricated assembled frame mold column quick positioning and splicing device provided in this embodiment, such as Figures 1-8As shown, the system includes: a first mold shell plate 1 and a second mold shell plate 2. Two first mold shell plates 1 and two second mold shell plates 2 are provided, and they are symmetrically arranged. The two first mold shell plates 1 and two second mold shell plates 2 enclose a frame column mold shell cavity. Positioning components 3 are provided on both sides of the first mold shell plates 1 and 2. The two symmetrically arranged first mold shell plates 1 and 2 are detachably connected via the positioning components 3. An installation plate 4 is detachably installed on one side of the outer surface of the first mold shell plate 1. One end of the installation plate 4 has a load-bearing base plate 404 connected to the ground. Insertion holes 103 are provided on the lower surface of the first mold shell plates 1 and 2. Insertion rods 101 are fixedly installed at both ends of the upper surface of multiple first mold shell plates 1 and 2. Lifting holes 102 are provided on one side of each insertion rod 101 for on-site lifting and transportation of the mold shell plates. Two triangular base blocks 403 are installed on one side of the mounting plate 4. The mounting plate 4 is bolted to both sides of the first mold shell plate 1. The upper surface of each of the two triangular base blocks 403 is provided with insertion holes. Two sets of first ear plates 405 are installed on one side of the mounting plate 4. Each of the two sets of first ear plates 405 is rotatably connected to an upper inclined support rod 401 by a pin. The other end of each of the two upper inclined support rods 401 is rotatably connected to the load-bearing base plate 404 by a pin. A second ear plate 406 is installed on one side of the lower half of the mounting plate 4. A lower inclined support rod 402 is rotatably installed in the second ear plate 406 by a pin. The other end of the lower inclined support rod 402 is rotatably installed to the load-bearing base plate 404 by a pin.

[0022] Through the design of the first mold plate 1, the second mold plate 2, the positioning component 3, the upper inclined support rod 401, and the lower inclined support rod 402, the mold plates can be quickly hoisted on site using the lifting hole 102. During vertical splicing, the insertion rod 101 of the upper mold plate is aligned with the insertion hole 103 of the lower mold plate and inserted. Laterally, the positioning component 3 allows the first mold plate 1 and the second mold plate 2 to quickly connect and enclose the cavity. After the mounting plate 4 is fixed with the first mold plate 1, the angles of the upper inclined support rod 401 and the lower inclined support rod 402 are adjusted via pins. The connection between the load-bearing base plate 404 and the ground provides support. It provides bidirectional oblique support to counteract the lateral pressure and buoyancy during the casting of the mold cavity, reducing on-site casting procedures. The mold plate splicing process does not require complicated tools, shortening on-site operation time. The support structure and the mold plate work together to avoid mold displacement or deformation during casting, improving the forming accuracy and construction stability of the frame column. When the mounting plate 4 is fixed to one side of the first mold plate 1 with bolts, the stability can be strengthened by inserting another set of bolts into the insertion holes on the triangular bottom block 403 installed on one side of the mounting plate 4. In addition, the time spent installing the ear plate can be reduced when installing the diagonal brace.

[0023] Example 2 The prefabricated assembled frame mold column quick positioning and splicing device provided in this embodiment, such as Figures 3-8As shown, the system includes: a positioning assembly 3 comprising a positioning insert plate 301 and positioning holes 306. The positioning insert plate 301 is fixedly installed on both ends of one side of the first mold shell plate 1, and the positioning holes 306 are opened on both sides of the second mold shell plate 2. The second mold shell plate 2 can be correspondingly engaged with the positioning insert plate 301 on one side of the first mold shell plate 1 through the positioning holes 306. Mounting holes 302 are opened at both ends of the first mold shell plate 1, and limiting rods 304 are fixedly installed on both sides of the second mold shell plate 2. When the second mold shell plate 2 is engaged with the positioning holes 306 through the positioning insert plate 301, the limiting rods 304 on both sides simultaneously pass into the mounting holes 302 at the corresponding ends of the first mold shell plate 1. The limiting rod 304 has a limiting hole 305 in the mounting hole 302 segment. A limiting plate 303 is installed and removed in the limiting hole 305. The limiting plate 303 and the first mold shell plate 1 have the same pin hole on one side. The pin hole in the first mold shell plate 1 passes through the mounting hole 302, and a positioning pin 307 is inserted into the pin hole. The positioning pin 307 passes through the pin hole to fix the limiting plate 303 and the first mold shell plate 1, so that the limiting rod 304 is fixed in the mounting hole 302.

[0024] Through the design of positioning insert plate 301, positioning hole 306, limiting rod 304, and positioning pin 307, when the first mold plate 1 and the second mold plate 2 are connected, the positioning insert plate 301 and the positioning hole 306 are precisely guided and engaged, quickly limiting the lateral displacement of the mold plate. The limiting rod 304 is simultaneously inserted into the mounting hole 302 to further constrain the vertical displacement. After the limiting plate 303 is inserted into the limiting hole 305, the positioning pin 307 passes through the pin hole to lock the limiting plate 303 and the first mold plate 1, forming multiple positioning constraints. The splicing process does not require repeated calibration, improving positioning efficiency. The locking structure is stable and reliable, preventing the mold plate splicing joint from loosening, reducing the risk of leakage in the on-site pouring process, and ensuring the sealing and integrity of the mold cavity during the pouring process. At the same time, when disassembling, only the positioning pin 307 and the limiting plate 303 need to be pulled out to separate the mold plate, further improving the construction efficiency and forming quality of the frame column.

[0025] In summary, the prefabricated modular frame shell column rapid positioning and splicing device provided in this embodiment has the following advantages: the first shell plate 1 and the second shell plate 2 are prefabricated and do not require on-site cutting; the positioning insert plate 301, positioning hole 306, limiting rod 304, limiting plate 303, and positioning pin 307 reduce manual adjustment; the insertion rod 101 and insertion hole 103 enable rapid vertical splicing; the lifting hole 102 facilitates hoisting; the mounting plate 4, upper inclined support rod 401, lower inclined support rod 402, and load-bearing base plate 404 simplify the reinforcement process; the standardized components are adaptable to multiple sub-projects, shorten the operation cycle, and improve construction efficiency and forming quality.

[0026] In use, the first mold plate 1 and the second mold plate 2 are hoisted through the lifting hole 102. When vertically splicing, the insertion rod 101 of the upper mold plate is inserted into the insertion hole 103 of the lower mold plate. When horizontally connecting, the positioning insert plate 301 of the first mold plate 1 is inserted into the positioning insert hole 306 of the second mold plate 2. At the same time, the limiting rod 304 of the second mold plate 2 is inserted into the mounting hole 302 of the first mold plate 1. The limiting plate 303 is inserted into the limiting hole 305 of the limiting rod 304. Then, the positioning pin 307 is used to lock the pin hole between the limiting plate 303 and the first mold plate 1. The mounting plate 4 is fixed to the first mold plate 1 with bolts. The upper inclined support rod 401 and the lower inclined support rod 402 are connected to the load-bearing base plate 404 after the angle is adjusted by the pin shaft. The connection between the load-bearing base plate 404 and the ground forms an inclined support, completing the assembly, positioning and stabilization of the mold column.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
