Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a modular hoisting formwork that is easy to reuse. Background Technology

[0002] In the construction process of building engineering, in order to achieve certain building functions such as bathrooms and balconies, there are structures with different heights marked between adjacent components, which are called high-low spans. The side formwork construction at the high-low spans is also called suspended formwork construction.

[0003] To facilitate mold turnover, existing suspended formwork construction usually adopts a combined suspended formwork, generally aluminum formwork, mainly composed of side formwork and L-shaped corner formwork. The L-shaped corner formwork occupies a large space during turnover, increasing transportation costs; at the same time, two different shapes of formwork need to be designed, increasing manufacturing costs.

[0004] Based on this, this application provides a modular lifting formwork that is easy to reuse to solve the above problems. Utility Model Content

[0005] This utility model aims to solve the technical problems existing in the prior art. To this end, this utility model provides a modular lifting mold that is easy to reuse, enabling assembly using a single type of template, eliminating the need to design L-shaped corner molds, reducing mold manufacturing costs, and also reducing mold transportation costs.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A modular formwork for easy reuse is provided, comprising side templates, corner bracing assemblies, and interlocking connectors. The side templates include a panel, crossbeams located on the back of the panel near the top and bottom, and connecting blocks at both ends of the crossbeams. One end of the panel has equally spaced grooves, and the other end has tenons that interlock with the grooves. Multiple side template panels are joined by tenons and grooves to form a regular polygonal closed frame. Vertically joined adjacent side templates are fixedly connected to the crossbeams via corner bracing assemblies. Horizontally joined adjacent side templates are fixedly connected to the connecting blocks of the crossbeams via interlocking connectors.

[0008] In some alternative embodiments, the gusset assembly includes a gusset rod and a bolt assembly, with both ends of the gusset rod being fixedly installed on the crossbeams of two perpendicularly spliced ​​side templates by the bolt assembly.

[0009] In some alternative embodiments, the splicing connector includes a screw and two nuts, the two ends of which pass through the connecting blocks on the crossbeams of the two adjacent side templates that are horizontally spliced ​​and are then locked by the nuts.

[0010] In some alternative embodiments, the crossbeam is made of channel steel, with its open side facing away from the panel.

[0011] In some alternative embodiments, the side formwork further includes longitudinal beams, with multiple longitudinal beams disposed between the two transverse beams.

[0012] In some alternative embodiments, the panel is provided with thickened portions at both ends of the crossbeam.

[0013] In some alternative embodiments, the panel is made of wood, aluminum alloy, or steel.

[0014] In some alternative implementations, the side templates are provided with various lengths for combination assembly into hanging molds of different specifications.

[0015] In some alternative embodiments, the method also includes bracing beams, the ends of which are fixedly mounted to the crossbeams of two oppositely arranged side templates by bolt assemblies.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses grooves and tenons to splice the side templates, and fixes them with corner braces and splicing connectors. This splicing structure eliminates the need to design L-shaped corner templates, and only requires the uniform production of the same type of side templates, which greatly reduces the manufacturing cost of the mold. At the same time, the same type of side templates can be stacked to prevent damage, and the space occupied during turnover is small, which reduces transportation costs. Attached Figure Description

[0028] Example 1

[0029] This embodiment provides a modular lifting formwork that is easy to reuse, as shown in the attached figure. Figure 1 As shown, it includes side template 1, corner brace assembly 2, and splicing connector 3, wherein:

[0030] As attached Figure 1 and attached Figure 2As shown, the side template 1 includes a panel 1.1, a crossbeam 1.2 located on the back of the panel near the top and bottom, and connecting blocks 1.3 located at both ends of the crossbeam. One end of the panel 1.1 has equally spaced grooves 1.1.0, and the other end has a tenon 1.1.1 that interlocks with the grooves 1.1.0. Multiple side template panels 1.1 are joined together by tenons 1.1.1 and grooves 1.1.0 to form a regular polygonal closed frame, generally a square closed frame, but the specific design depends on the requirements. In this embodiment, the panel 1.1 can be made of wood (preferably plywood), aluminum alloy, or steel.

[0031] As attached Figure 1 As shown, the two adjacent side templates 1 that are vertically spliced ​​are fixedly connected to the crossbeam 1.2 by a bracket assembly 2. Preferably, the bracket assembly 2 includes a bracket rod 2.1 and a bolt assembly 2.2, and the two ends of the bracket rod 2.1 are respectively fixedly installed on the crossbeam 1.2 of the two vertically spliced ​​side templates 1 by the bolt assembly 2.2.

[0032] As attached Figure 1 and attached Figure 3 As shown, the two adjacent side templates 1 that are horizontally spliced ​​are fixedly connected to the crossbeam 1.2 via a splicing connector 3 and a connecting block 1.3. Preferably, the splicing connector 3 includes a screw 3.1 and two nuts 3.2. The two ends of the screw 3.1 pass through the connecting blocks 1.3 on the crossbeam 1.2 of the two adjacent side templates 1 that are horizontally spliced ​​and are respectively locked by the nuts 3.2.

[0033] To facilitate the installation of the splicing connectors and corner braces, the crossbeam 1.2 in this embodiment is preferably made of channel steel, with its open side facing away from the panel. This allows both the threaded rods and corner braces to be housed within the channel steel.

[0034] Preferably, the side formwork 1 in this embodiment has multiple length specifications. Different specifications of side formwork can be assembled into different specifications of hanging formwork by selecting different specifications of side formwork according to the construction process dimensions to meet the construction requirements.

[0035] Example 2

[0036] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 3 As shown, in this embodiment, multiple longitudinal beams 1.4 are also provided on the back of the side formwork 1 between the two horizontal beams 1.2 to strengthen the structural strength of the side formwork.

[0037] Example 3

[0038] Based on Embodiment 1 or Embodiment 2, this embodiment preferably provides thickened portions 1.1a at both ends of the panel 1.1 of the side template 1 located at the crossbeam 1.2, which can increase the thickness of the side template splice and improve the bonding strength of the splice.

[0039] Example 4

[0040] Based on any of the above embodiments, this embodiment also includes a support beam 4, as shown in the attached figure. Figure 1 As shown, the two ends of the multiple supporting beams 4 are fixedly installed on the crossbeams 1.2 of the two oppositely arranged side templates 1 by bolt assemblies 2.2. The supporting beams can increase the structural strength of the closed frame and prevent the side templates from expanding.
