[0029] The following describes embodiments of the present invention in conjunction with the accompanying drawings. The described embodiments are only a part of the embodiments of the invention, rather than all the embodiments.

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0031] The embodiments described below with reference to the accompanying drawings are exemplary and intended only to explain the present invention and are not to be construed as limiting the present invention. In describing the present invention, it should be understood that terms such as "install," "connect," "fix," and "plug in" are to be understood broadly, encompassing direct connection, installation, fixation, or plugging, as well as indirect connection, installation, fixation, or plugging, and the present invention is not intended to limit these terms.

[0032] like Figures 1 to 7 As shown, a schematic diagram of an embodiment of a quick-plug elevator shaft template structure of the present invention includes a plurality of mutually enclosed side templates 1; corner connectors 2, which are used to connect adjacent side templates 1, and the corner connectors 2 are plugged into the side templates 1; transverse support plates 3, both ends of which are respectively connected to corresponding corner connectors 2, and at least one transverse support plate 3 is installed between each two adjacent corner connectors 2 for reinforcement; and a bracing assembly, wherein each pair of transverse support plates 3 of equal height and oppositely arranged are connected to each other through a bracing assembly for bracing. Preferably, the number of the side templates 1 and the number of the corner connectors 2 are both four, which are connected to each other to form a closed rectangular structure. The ends of the transverse support plates 3 are plugged into the corresponding corner connectors 2. It should be understood that in different embodiments, the plugging can be direct plugging or indirect plugging.

[0033] This embodiment adopts a plug-in and bracing assembly method to replace the traditional fastener-type scaffolding construction method, which can improve construction efficiency; the two ends of the transverse support plate 3 can support the corresponding corner connectors 2, and the bracing assembly can reinforce the transverse support plate 3 and support multiple transverse support plates 3 of relatively equal height. The bracing assembly is matched with the transverse support plate 3, which can support in multiple directions inside the elevator shaft template structure to reduce the problem of biased deformation of the side template 1. The side template 1 is connected by the prefabricated corner connector 2 to ensure that the adjacent side templates 1 are accurately docked and densely spliced, which is convenient for discovering installation deviations during construction and reducing the hidden dangers of mold expansion.

[0034] Preferably, the corner connector 2 defines a slot 21 for connecting to the side formwork 1. This slot 21 extends vertically through the corner connector 2, defining the template's insertion position. This facilitates quick and precise assembly and reduces misalignment of adjacent side formwork 1 during construction. The height of the corner connector 2 is equal to that of the side formwork 1. This fully covered, high-height connection eliminates weak points in the segmented supports, prevents stress concentration, and evenly transmits force, ensuring the service life of each component and improving construction quality.

[0035] In this embodiment, a plurality of positioning plates 4 are further included, through which the transverse support plates 3 are plugged into the corner connectors 2. Preferably, the corner connectors 2 are L-shaped structures. The right-angle structure better ensures that the multiple side templates 1 are enclosed into a rectangular structure. The multiple side templates 1 and the corner connectors 2 are assembled into a whole and restrain each other to ensure structural stability. The positioning plates 4 are square to adapt to the corner connectors 2. Each corner connector 2 is provided with multiple positioning plates 4 at intervals along the height direction. In other embodiments, reinforcing ribs are provided on the inner side of the L-shaped corner connector 2 to increase the bending strength.

[0036] In this embodiment, the positioning plate 4 defines mounting holes 41, and the transverse support plate 3 has connectors 31 at both ends for insertion into the mounting holes 41. Two sides of the square positioning plate 4 are used to connect with the L-shaped corner connector 2, while the other two sides define mounting holes 41 at corresponding locations for insertion into the transverse support plate 3. Both ends of the transverse support plate 3 extend downward to form the connectors 31. The mounting holes 41 are elongated, with a length no less than the width of the connector 31, and a width no less than the thickness of the connector 31, ensuring a compatible interlocking connection.

[0037] In this embodiment, the support assembly includes a retractable bracket and a support member 5 connected to the bracket, and the support member 5 is plugged into the corresponding horizontal support plate 3. Preferably, the support member 5 is a U-shaped fixture, and its opening is used to plug into the horizontal support plate 3.

[0038] In this embodiment, the bracket includes a bracket body and a plurality of telescopic rods 8 movably connected to the bracket body. Ends of the telescopic rods 8 away from the bracket body are connected to the support member 5.

[0039] In this embodiment, the bracket body includes an outer sleeve 6 and multiple threaded adjustment tubes 7. A telescopic rod 8 is threaded and movably mounted within the outer sleeve 6. The telescopic rod 8 is fixed in its telescopic length by corresponding threaded adjustment tubes 7. The telescopic rod 8 mates with the internal threads of the threaded adjustment tubes 7 to achieve telescopic adjustment and precise support. The threaded engagement also provides better resistance to vibration and impact during construction, ensuring structural stability.

[0040] In this embodiment, the support body is cross-shaped. Specifically, the outer sleeve 6 is cross-shaped, which supports the four side formworks 1 in cooperation with the four threaded adjusting pipes 7 and the four telescopic rods 8. Preferably, the cross-shaped support assembly can be telescoped in four directions, uniformly distribute the four-way load, and can also be telescoped and adjusted to a central symmetric structure to resist the deformation of the side formwork 1.

[0041] In this embodiment, each corner connecting piece 2 is fixedly connected with a plurality of positioning plates 4. In another embodiment, the corner connecting piece 2 can be provided with a plurality of embedded grooves in the height direction for inserting the positioning plate 4, so as to realize the height adjustment of the positioning plate 4. An elastic rubber pad can be arranged in the embedded groove to form a buffer for the positioning plate 4, eliminate the assembly gap, and improve the friction force, so as to ensure the stability of the insertion of each positioning plate 4 and the corresponding corner connecting piece 2.

[0042] On the other hand, the application also provides a construction method of the quick-insertion type elevator shaft formwork structure, which comprises the following steps:

[0043] S1. Positioning and installation, according to the size of the elevator shaft, accurately fixing the vertically arranged corner connecting piece 2 at the corner position, and confirming that the included angle of the L-shaped corner connecting piece 2 is inward, so as to be inserted with the side formwork 1 to form a polygonal structure, preferably a general rectangular structure.

[0044] S2. Inserting the side formwork 1, inserting the side formwork 1 with the corresponding corner connecting piece 2, that is, inserting into the insertion slot 21 of the corresponding corner connecting piece 2, and surrounding a plurality of side formworks 1 to form a polygonal structure, preferably a rectangular structure, to complete the preliminary installation of the shaft four-wall formwork.

[0045] S3. Installing the horizontal support plate 3, connecting the two ends of the horizontal support plate 3 with the corresponding corner connecting piece 2 at the required height, and arranging a plurality of horizontal support plates 3 at the same height to form a polygonal support frame, and arranging at least one horizontal support plate 3 between the two adjacent corner connecting pieces 2, specifically, inserting the insertion part 31 of the horizontal support plate 3 into the mounting hole 41 of the adjacent two corresponding positioning plates 4 at the same height, arranging every four horizontal support plates 3 at the same height to form an internal rectangular support frame, and arranging a plurality of groups along the height of the side formwork 1 to preliminarily support the side formwork 1.

[0046] S4. Install the bracing assembly, place the bracing assembly in the center of the corresponding polygonal support frame and tighten the bracing assembly against the transverse support plates. Specifically, place the bracing assembly in the center of the rectangular frame formed by the four transverse support plates 3 at the same height, adjust the size of the cross-shaped bracing assembly, rotate the threaded adjusting tube 7 to preliminarily adjust the extension length of the telescopic rod 8 relative to the outer sleeve tube 6, insert the corresponding bracing member 5 into the middle of each transverse support plate 3, and then finely adjust the telescopic amount of the telescopic rod 8 to make the bracing assembly extend in four directions and tightly press against the corresponding transverse support plates 3. Preferably, the extension lengths of the four telescopic rods 8 of each bracing assembly are kept consistent to ensure uniform bracing force.

[0047] At the positioning plates 4 at different heights of the corner connectors 2, steps S3 and S4 are repeated to install multiple layers of transverse support plates 3 and bracing assemblies to form multiple layers of reinforced bracing.

[0048] The embodiment does not need to build a fastener type scaffold, but uses a quick socket type to build, which can improve the construction efficiency, the bracing type assembly ensures the stability of the formwork reinforcement, the prefabricated corner connector is inserted into the formwork, which not only facilitates the personnel construction operation, but also ensures the precise butt joint of the formwork, has a simple structure, high construction efficiency, and can improve the construction quality.
