Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for building construction, specifically to a cantilever support structure for a formwork support. Background Technology

[0002] For multi-story buildings with unique shapes or special structures, there are often cantilevered slabs and beams extending beyond the edge of the next floor in certain areas. During construction, it is often necessary to set up cantilevered footing points in certain areas of the formwork support. In all these cases, cantilevered support structures need to be installed within the formwork support. Currently, the conventional practice for setting up cantilevered support structures is to erect full-span scaffolding of the corresponding length based on the required cantilever length. This method is complex, time-consuming, and requires significant material and labor costs. To address these issues, existing technology has developed a solution where the cantilevered support frame is directly connected to the side of the main support frame of the formwork support, and diagonal bracing is installed at the bottom of the cantilevered support frame and the main support frame. For example, the solution disclosed in Chinese Utility Model Patent Publication No. CN220565677U. However, in this scheme, the cantilever support structure and the bottom diagonal brace are directly connected to the side of the main support frame. All the load of the cantilever support structure is borne by the side of the main support frame, and the main support frame will be subjected to eccentric load. This has the disadvantages of poor support capacity, easy collapse, and low safety. The above problems are particularly prominent when the load of the cantilever support structure is large and the cantilever length is large. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a cantilever support structure for formwork supports that can reduce material input, lower costs, improve construction efficiency, and enhance the support capacity and safety of formwork supports.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A cantilever support structure for a template bracket includes a main support frame built on an installation foundation and a cantilever support frame connected to the side of the main support frame. Multiple bottom cantilever supports located below the cantilever support frame are connected and installed on the installation foundation, and the lower end of the cantilever support frame is supported on the multiple bottom cantilever supports.

[0005] As a further improvement to the above technical solution: The bottom cantilever support includes a support beam and one or more diagonal braces connected to the support beam. The support beam is connected to and installed on the mounting foundation via a first detachable connection assembly and extends outward from the mounting foundation. The diagonal brace extends downward at an incline and is connected and fixed to the mounting foundation via a second detachable connection assembly.

[0006] The first detachable connection assembly includes a first mounting base and a plurality of first pre-embedded fasteners pre-embedded on the mounting base. The first mounting base includes a first base plate, which is attached to the surface of the mounting base and connected and fixed by the plurality of first pre-embedded fasteners. The first base plate is provided with a support member, and the support beam is supported on the support member and connected and fixed to the support member.

[0007] The support member is a U-shaped plate welded to the side of the first base plate opposite to the mounting foundation. The U-shaped plate includes a horizontal plate portion connected to the first base plate and two vertical plate portions connected between the horizontal plate portion and the first base plate on both sides. The support beam is supported on the horizontal plate portion.

[0008] The second detachable connection assembly includes a second mounting base and a plurality of second pre-embedded fasteners embedded in the mounting base. The second mounting base includes a second base plate and two limiting side plates spaced apart on the second base plate. The second base plate is attached to the surface of the mounting base and is connected and fixed by the plurality of second pre-embedded fasteners. The diagonal brace is inserted and positioned between the two limiting side plates and is connected and fixed to the two limiting side plates.

[0009] The installation foundation includes an upper floor structure, a lower floor structure located below the upper floor structure, and a second-lower floor structure located below the lower floor structure. The main support frame is installed on the upper floor structure. The support beam is connected and installed on the top surface or exterior facade of the lower floor structure via a first detachable connection component. The diagonal brace is connected and installed on the top surface or exterior facade of the second-lower floor structure via a second detachable connection component.

[0010] The installation base is a building structure, the support beam is connected and installed on the exterior of the building structure through a first detachable connecting component, and the diagonal brace is connected and installed on the exterior of the building structure through a second detachable connecting component.

[0011] A reinforcing link is also connected between the middle of the diagonal brace and the support beam.

[0012] The cantilever support structure of the template bracket also includes multiple distribution beams that span across multiple bottom cantilever supports, with the lower end of the cantilever support frame supported on the multiple distribution beams.

[0013] The main support frame is also connected to the support beam by one or more inclined ropes.

[0014] Compared with the prior art, the advantages of this utility model are: The cantilever support structure of this utility model for formwork supports has multiple bottom cantilever supports installed on the installation foundation. These multiple bottom cantilever supports provide support to the lower end of the cantilever support frame. Compared with the traditional method of erecting full-span scaffolding, this method can reduce material input, lower costs, and improve construction efficiency. At the same time, the main load of the cantilever support frame acts on the bottom cantilever supports connected to the installation foundation, which can greatly reduce the load and eccentric load on the main support frame, making the formwork support less prone to collapse and improving the support capacity and safety of the formwork support.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1 like Figure 1 As shown, the cantilever support structure of the formwork support in this embodiment includes a main support frame 1 erected on an installation foundation 100 and a cantilever support frame 2 connected to the side of the main support frame 1. Multiple bottom cantilever supports 3 located below the cantilever support frame 2 are connected and installed on the installation foundation 100, and the lower end of the cantilever support frame 2 is supported on the multiple bottom cantilever supports 3. This cantilever support structure of the formwork support, by installing multiple bottom cantilever supports 3 on the installation foundation 100, provides support to the lower end of the cantilever support frame 2. Compared to the traditional method of erecting full-span scaffolding, this reduces material input, lowers costs, and improves construction efficiency. Simultaneously, the main load of the cantilever support frame 2 acts on the bottom cantilever supports 3 connected to the installation foundation 100, which greatly reduces the load and eccentric load on the main support frame 1, making the formwork support less prone to collapse and improving its support capacity and safety.

[0025] In this embodiment, the bottom cantilever support 3 includes a support beam 31 and a diagonal brace 32 connected to the support beam 31. The support beam 31 is connected to and installed on the installation foundation 100 via a first detachable connecting assembly 4 and extends outward from the installation foundation 100. The diagonal brace 32 extends downward at an incline and is connected and fixed to the installation foundation 100 via a second detachable connecting assembly 5. By connecting one end of the support beam 31 to the installation foundation 100 via the first detachable connecting assembly 4 and fixing the diagonal brace 32 to the installation foundation 100 via the second detachable connecting assembly 5, the installation and fixing of the bottom cantilever support 3 can be completed. Then, the cantilever support frame 2 can be erected on the support beam 31. This bottom cantilever support 3 has good load-bearing capacity and has the advantages of simple structure, low cost, good support stability, and convenient assembly and disassembly. The bottom cantilever support 3 is preferably made of welded steel profiles.

[0026] In this embodiment, as Figure 2As shown, the first detachable connection assembly 4 includes a first mounting base 41 and a plurality of first pre-embedded fasteners 42 pre-embedded on the mounting base 100. The first mounting base 41 includes a first base plate 411. The first base plate 411 is attached to the surface of the mounting base 100 and connected and fixed by the plurality of first pre-embedded fasteners 42. The first base plate 411 is provided with a support member 412. The support beam 31 is supported on the support member 412 and connected and fixed to the support member 412. During installation, the first base plate 411 is brought into contact with the surface of the mounting base 100 and connected and fixed with multiple first pre-embedded fasteners 42 embedded in the mounting base 100. Then, one end of the support beam 31 is supported on the support member 412, and the support beam 31 is connected and fixed to the first mounting seat 41 by welding or bolting. The installation is simple, and the support member 412 supports the support beam 31. The main load on the support beam 31 is directly applied to the support member 412, rather than being transmitted through welding points or bolts, which can improve the load-bearing capacity of the first mounting seat 41 and ensure safety and reliability.

[0027] Preferred, such as Figure 5 As shown, the support member 412 is a U-shaped plate welded to the side of the first base plate 411 opposite to the mounting base 100. The U-shaped plate includes a horizontal plate portion 4121 connected to the first base plate 411 and two vertical plate portions 4122 connected between the horizontal plate portion 4121 and the first base plate 411 on both sides. The support beam 31 is supported on the horizontal plate portion 4121. This support member 412 has a high load-bearing capacity, and its structure is simple, low in cost, and easy to process and manufacture.

[0028] In this embodiment, as Figure 3 and Figure 6As shown, the second detachable connection assembly 5 includes a second mounting base 51 and a plurality of second pre-embedded fasteners 52 pre-embedded on the mounting base 100. The second mounting base 51 includes a second base plate 511 and two limiting side plates 512 spaced apart on the second base plate 511. The second base plate 511 is attached to the surface of the mounting base 100 and is connected and fixed by the plurality of second pre-embedded fasteners 52. The diagonal brace 32 is inserted and positioned between the two limiting side plates 512 and is connected and fixed to the two limiting side plates 512. During installation, the second base plate 511 is brought into contact with the surface of the mounting base 100 and connected and fixed with multiple second pre-embedded fasteners 52 embedded in the mounting base 100. Then, the diagonal brace 32 is connected and fixed to the second mounting seat 51 by welding or bolting. This installation is simple. The diagonal brace 32 is inserted and positioned between the two limiting side plates 512 and connected and fixed to them. During installation, the two limiting side plates 512 provide positioning for the diagonal brace 32, facilitating installation. Furthermore, the diagonal brace 32 is simultaneously connected to both limiting side plates 512, ensuring a stable and reliable connection. In this embodiment, the first pre-embedded fastener 42 and the second pre-embedded fastener 52 are preferably pre-embedded bolts. The first base plate 411 and the support member 412 are both made of steel plates and are welded together to form the first mounting seat 41. The second base plate 511 and the limiting side plates 512 are also made of steel plates and are welded together to form the second mounting seat 51.

[0029] In this embodiment, the installation foundation 100 includes an upper floor structure 101, a lower floor structure 102 located below the upper floor structure 101, and a second-lower floor structure 103 located below the lower floor structure 102. The main support frame 1 is mounted on the upper floor structure 101. The support beam 31 is connected and installed on the exterior of the lower floor structure 102 via a first detachable connection component 4. The diagonal brace 32 is connected and installed on the exterior of the second-lower floor structure 103 via a second detachable connection component 5. The load of the cantilever support frame 2 can be transferred to the lower floor structure 102 and the second-lower floor structure 103 through the bottom cantilever support 3. The bottom cantilever support has good installation stability and high overall support capacity.

[0030] In other embodiments, the support beam 31 may be connected to the top surface of the next floor structure 102 via the first detachable connection component 4, and the diagonal brace 32 may be connected to the top surface of the second floor structure 103 via the second detachable connection component 5.

[0031] In this embodiment, a reinforcing connecting rod 33 is also connected between the middle part of the diagonal brace 32 and the support beam 31, which can improve the overall structural strength and support capacity of the bottom cantilever support 3.

[0032] In this embodiment, as Figure 4As shown, the cantilever support structure of the template bracket also includes multiple distribution beams 6 spanning multiple bottom cantilever supports 3, with the lower end of the cantilever support frame 2 supported on the multiple distribution beams 6. The number and position of the distribution beams 6 placed on the multiple bottom cantilever supports 3 can be flexibly adjusted. This allows for the installation of cantilever support frames 2 with different upright spacings even with a smaller number of bottom cantilever supports 3 and without needing to adjust the connection position between the bottom cantilever supports 3 and the installation foundation 100, improving the flexibility and applicability of use. Furthermore, by adjusting the number and position of the distribution beams 6, all uprights of the cantilever support frame 2 can be connected and supported, ensuring stable and reliable support.

[0033] In this embodiment, one or more inclined ropes 7 are connected between the main support frame 1 and the support beam 31. The inclined ropes 7 exert an upward lifting effect on the bottom cantilever support 3, which can further improve the support capacity of the bottom cantilever support 3.

[0034] In this embodiment, the first mounting base 41 is used to connect the mounting support beam 31, and the second mounting base 51 is used to connect the mounting diagonal brace 32. This achieves stable and reliable installation of the cantilever support frame 21 on the mounting foundation 100 while minimizing the installation space required.

[0035] Example 2 The cantilever support structure of the template bracket in this embodiment is basically the same as that in Embodiment 1, the main difference being that, Figure 7 As shown, in this embodiment, the installation foundation 100 is a building structure. The bottom cantilever support 3 is equipped with two diagonal braces 32. The support beam 31 is connected to and installed on the exterior facade of the building structure via a first detachable connecting assembly 4. Each diagonal brace 32 is also connected to and installed on the exterior facade of the building structure via a second detachable connecting assembly 5. The cantilever support structure of the formwork bracket in this embodiment is suitable for situations where only the exterior facade of the building structure can provide an installation location for the bottom cantilever support 3.

[0036] In other embodiments, the bottom cantilever support 3 may also be provided with a greater number of diagonal braces 32.

[0037] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
