Description

Technical Field

[0001] The utility model relates to the technical field of cantilever beam construction, and more specifically, to a template support and a construction template of a cantilever beam construction template. Background Art

[0002] In modern building construction, cantilever beams are a common building structural element, and their design and construction are of great significance to the safety and stability of the entire building. However, since cantilever beams usually extend beyond the main body of the building, their operation during the construction process becomes complicated. Especially when a climbing frame system is used for the main construction of the building, the extended part of the cantilever beam often becomes an obstacle for the climbing frame to climb. Therefore, in order to ensure the construction progress and work safety, the construction team usually performs a secondary pouring of the cantilever beam after the main building is completed. The secondary pouring requires the construction of a pouring formwork and a formwork support to ensure the smooth progress of the pouring process.

[0003] During the secondary pouring of cantilever beams, since the cantilever beams are usually set on the cantilever structure of the main building, such as balconies, the cantilever structure needs to bear a large load during the pouring process. The additional load affects the stability and structural strength of the cantilever structure. If it is not handled properly, it is easy to cause damage to the cantilever structure. More seriously, if the structural strength of the cantilever structure is weakened to a certain extent, it may cause the collapse of the entire cantilever structure, thereby causing serious production accidents.

[0004] The above shortcomings need to be improved. Utility Model Content

[0035] Example 1

[0036] like Figures 1 to 4 As shown, a formwork support for a cantilever beam construction formwork described in one embodiment of the utility model comprises a plurality of rows of vertical poles 1 connected to a building main body 9, longitudinal poles 2 are connected between each row of vertical poles 1, horizontal poles 3 are connected between each row of vertical poles 1, and the vertical poles 1 comprise formwork supporting vertical poles 101 for supporting a casting formwork 8, a balcony supporting vertical poles 102 are arranged on a first side of the formwork supporting vertical poles 101, and the balcony supporting vertical poles 102 are used to support a balcony connected to a cantilever beam 11 to be cast.

[0037] During the construction process, the position of the vertical pole 1 is first determined according to the construction drawings. The vertical pole 1 is stably connected to the building body 9 to form a solid foundation support. Then the longitudinal rods 2 and the cross bars 3 are installed between the vertical poles 1 to form a stable frame structure. The formwork support vertical pole 101 is the main structure for supporting the casting formwork 8 and is arranged below the casting formwork 8 to ensure the stability of the casting formwork 8. On the first side of the formwork support vertical pole 101, that is, the side of the formwork support vertical pole 101 close to the building body 9, the balcony support vertical pole 102 is installed. The balcony support vertical pole 102 will be used to support the balcony connected to the cantilever beam 11 to be cast.

[0038] In this embodiment, the vertical pole 1 used to support the formwork support is connected to the building body 9, and the vertical pole 1, the longitudinal pole 2, and the horizontal pole 3 form a stable frame, which can evenly distribute the load and vibration during the pouring process, reduce the pressure on the cantilever structure 10 such as the balcony, and effectively prevent the cantilever structure 10 from being damaged due to excessive load. In addition, by providing the formwork support vertical pole 101 and the balcony support vertical pole 102, the pouring formwork 8 and the balcony structure are supported respectively, the stability and safety of the pouring formwork 8 and the balcony structure are ensured, and the construction quality is improved.

[0039] like Figure 1 and Figure 2 As shown, in a preferred embodiment, a protective support upright 103 is provided on the second side of the formwork support upright 101 , and the top height of the protective support upright 103 is higher than the top elevation of the cantilever beam 11 .

[0040] During the construction process, the position of the protective support pole 103 is first determined. The protective support pole 103 is located on the second side of the formwork support pole 101, that is, the side away from the building body 9, to ensure that its top height is higher than the top elevation of the cantilever beam 11, and the height difference with the cantilever beam 11 is 1.2m, that is, higher than the center of gravity of the construction workers. Then, the protective support pole 103 is firmly connected to the horizontal bar 3 and the longitudinal bar 2 using appropriate connectors such as connecting buckles to ensure its stability and safety.

[0041] In this embodiment, by setting the protective support pole 103 higher than the cantilever beam 11 and with a height difference of 1.2m from the cantilever beam 11, accidents such as falling are prevented, and the safety of construction workers is effectively protected. In addition, the firm connection between the protective support pole 103 and the crossbar 3 and the longitudinal bar 2 also ensures the stability of the entire formwork support, further enhancing the safety during the construction process. In actual application, the height difference between the protective support pole 103 and the cantilever beam 11 can be set according to actual construction needs, generally not less than 1.2m.

[0042] like Figure 1 As shown, in a preferred embodiment, a wall connecting member 4 is provided on the protective support upright 103 , and the wall connecting member 4 extends into the mold cavity of the casting template 8 and is connected to the cantilever beam 11 skeleton.

[0043] During the construction process, first determine the installation position of the wall connecting piece 4 on the protective support upright 103 to ensure that it can be effectively connected to the cantilever beam 11 skeleton in the mold cavity of the casting template 8. Then, fix the wall connecting piece 4 on the protective support upright 103 by connecting buckles, tying or welding, and ensure that it is stable and reliable. Then, the part of the wall connecting piece 4 that extends into the mold cavity is tightly connected to the cantilever beam 11 skeleton, and the wall connecting piece 4 is connected to the cantilever beam 11 skeleton by tying or welding. In this example, the cantilever beam 11 is cast twice, and the width of the two castings is different. The first casting area is located below the second casting area, and the width of the first casting area is larger. The wall connecting piece 4 goes deep into the two casting areas from top to bottom. After the first casting is completed, the first casting part is integrated with the cantilever structure 10 such as the balcony. At this time, the wall connecting piece 4 supports the cantilever beam 11 through the protective support upright 103 on the one hand, and pulls the protective support upright 103 through the cantilever beam 11 on the other hand to prevent the protective support upright 103 from tipping over. After the first pouring part solidifies, the second pouring is carried out. At this time, the wall connecting piece 4 is used to connect the first pouring part and the second pouring part. After the pouring is completed, the excess part of the wall connecting piece 4 can be cut. In actual application, the number of pouring times of the cantilever beam 11 can be determined according to the construction requirements and the construction environment, that is, it can be cast once or multiple times. It should be noted that no matter how many times the pouring is performed, the wall connecting piece 4 goes deep into each pouring area.

[0044] The wall connecting piece 4 extends into the mold cavity of the casting template 8 and is connected to the skeleton of the cantilever beam 11. On the one hand, it enhances the overall stability of the template support. On the other hand, during the casting process of the cantilever beam 11, the wall connecting piece 4 can assist in pulling the cantilever beam 11 and share part of its load, thereby reducing the burden of the template support uprights 101, improving the bearing capacity of the entire template support, and reducing the load on the balcony to ensure the stability of the balcony. In addition, the tight connection between the wall connecting piece 4 and the skeleton of the cantilever beam 11 can also effectively prevent the template support from displacement or deformation during the casting process, ensuring the stability of the template support. In addition, the wall connecting piece 4 can tie the concrete poured twice, so that the concrete poured twice can be tightly connected to prevent structural defects caused by loose connection.

[0045] like Figure 1 As shown, in a preferred embodiment, the balcony support uprights 102 and the protection support uprights 103 adjacent to the formwork support uprights 101 are symmetrically arranged with respect to the formwork support uprights 101 .

[0046] During the construction process, the position of the formwork support pole 101 is determined according to the construction drawings and design requirements, so that it stands vertically below the casting formwork 8. Subsequently, the balcony support poles 102 and the protection support poles 103 are symmetrically arranged on both sides of the formwork support pole 101, respectively, based on the formwork support pole 101. During the installation process, the spacing and verticality between the poles 1 meet the construction requirements, ensuring the symmetrical relationship between the balcony support poles 102 and the protection support poles 103 and the formwork support poles 101. Through measurement and adjustment, the balcony support poles 102 and the protection support poles 103 are installed and positioned, and a stable support structure is formed between the formwork support poles 101.

[0047] In this embodiment, the balcony support poles 102 and the protective support poles 103 are symmetrically arranged to ensure the structural balance of the construction formwork support of the cantilever beam 11, effectively preventing structural stress or deformation caused by uneven force, and improving the structural stability of the cantilever beam 11 and its connected balcony, and prolonging their service life. Secondly, the symmetrical design enhances the overall stability of the formwork support, enabling it to resist interference from external factors such as wind and vibration, ensuring safety during construction.

[0048] like Figure 2 and Figure 3 As shown, in a preferred embodiment, a first scissors strut 5 is vertically arranged on the protective support upright 103, and a second scissors strut 6 is horizontally arranged on the bottom cross bar 3.

[0049] During the construction process, the construction workers measured and marked the positions of the first scissors brace 5 and the second scissors brace 6 according to the construction drawings and design requirements. Then, using appropriate connectors and fastening tools, the first scissors brace 5 is vertically installed on the protective support pole 103 to ensure that it is tightly connected to the pole 1 and can provide effective support. Next, the second scissors brace 6 is horizontally installed on the bottom crossbar 3 to ensure that it is firmly fixed on the crossbar 3 and forms a stable support network with the first scissors brace 5.

[0050] By setting the first scissors brace 5 on the protective support upright 103 and the second scissors brace 6 on the bottom cross bar 3, the overall stability and rigidity of the template support structure are enhanced, effectively preventing the support structure from being deformed or unstable due to external factors such as wind or loads generated during construction, and ensuring the construction quality of the cantilever beam 11 and the safety of the balcony connected to it. Secondly, the mutual cooperation of the first scissors brace 5 and the second scissors brace 6 forms a stable support network, which enables the support structure to transmit force more evenly when bearing loads, further improving the bearing capacity and stability of the structure.

[0051] In a preferred embodiment, a protective net is arranged on the protective support upright pole 103, and a pedal is arranged on the bottommost cross bar 3. The pedal comprises a wooden square arranged at the bottom, and the wooden square is fully covered with plywood, and the plywood is connected to the wooden square.

[0052] During the construction process, the construction workers customize a suitable protective net according to the size and shape of the protective support pole 103, and use connecting tools such as wire to firmly fix it on the pole 1. Then, the pedal is installed. The pedal is mainly composed of wooden planks and plywood spread on the wooden planks. The construction workers first lay the wooden planks to ensure that the wooden planks are flat and firmly placed on the crossbar 3. Then, plywood is spread on the wooden planks, and nails or other appropriate connection methods are used to tightly fix the plywood and the wooden planks, providing a stable standing and walking platform for the construction workers to prevent loosening or slipping when the workers step on them.

[0053] By setting a protective net on the protective support upright 103 and a pedal on the bottom cross bar 3, the protective net effectively prevents the risk of people and objects falling from a height, provides a safe construction environment for workers, reduces work-related accidents, and protects the lives of workers. Secondly, the pedal is set to provide workers with a stable standing and walking platform, and the combination of wooden squares and plywood enhances the carrying capacity and stability of the pedal, so that workers can work more comfortably and stably during the construction process, improving work efficiency and safety. In addition, an anti-slip structure can be set on the plywood to increase the roughness of the plywood surface, so that construction workers can stand and walk stably even in adverse weather conditions, further ensuring the safety and reliability of the construction process.

[0054] like Figure 1 and Figure 4 As shown, in a preferred embodiment, one end of the formwork supporting upright 101 and one end of the balcony supporting upright 102 are respectively provided with a length adjusting member 104, and the length adjusting member 104 is used to adjust the length of the formwork supporting upright 101 or the balcony supporting upright 102 so that both ends thereof are pressed tightly against each other.

[0055] During the construction process, the construction personnel first determine the precise lengths of the template support poles 101 and the balcony support poles 102 according to the specific dimensions of the cantilever beam 11 and the balcony and the requirements of the construction drawings. Then, the length of the pole 1 is fine-tuned using the length adjustment member 104 to ensure that the two ends of the pole 1 can be pressed against the building body 9 and the cantilever beam 11 or the balcony, thereby achieving stable support. The length adjustment member 104 generally includes a support block, a screw connected to the support block, and an adjustment block threadedly connected to the screw. The construction personnel change the position of the adjustment block on the screw by rotating the adjustment block, thereby adjusting the effective length of the pole 1. In actual application, the height adjustment member 702 can be set at the top of the pole 1 or at the bottom of the pole 1. In addition, the height adjustment member 702 can also use a hydraulic telescopic rod, an electric telescopic rod, etc.

[0056] By providing the length adjusting member 104 on the supporting pole 1 and the balcony supporting pole 102, the length of the pole 1 can be quickly and accurately adapted to different construction requirements, ensuring that both ends of the pole 1 are tightly pressed together, and both the cantilever beam 11 and the balcony can achieve stable support, thereby enhancing the stability and safety of the entire supporting structure, and ensuring the safety of construction workers and the quality of construction. The use of the length adjusting member 104 improves construction efficiency and reduces material waste caused by size mismatch.

[0057] In a preferred embodiment, the upright pole 1 is a steel pipe, and the bottom of the steel pipe is sealed.

[0058] During the construction process, first select a steel pipe that meets the specification requirements as the vertical pole 1, and then seal the bottom of the steel pipe to prevent debris from entering the pipe, thereby preventing debris from falling from the steel pipe. Generally, a special sealing agent or welding method is used. After the sealing is completed, the vertical pole 1 is installed. According to the construction drawings, the vertical pole 1 is fixed at a predetermined position to ensure verticality and stability. In actual operation, the bottom of the vertical pole 1 can be sealed when it is fixed. In addition, the longitudinal rod 2 and the cross rod 3 are also steel pipes.

[0059] In this embodiment, a steel pipe is used as the vertical pole 1. On the one hand, the high strength and stability of the steel pipe ensure that the vertical pole 1 is not easily deformed or damaged during use, effectively extending the service life. On the other hand, the bottom plugging effectively prevents debris from entering the pipe and preventing debris from falling from the steel pipe and injuring people.

[0060] Example 2

[0061] like Figure 4 As shown, a cantilever beam construction template in one embodiment of the utility model includes a template support of the above-mentioned cantilever beam construction template.

[0062] In this embodiment, the formwork support is a stable frame composed of vertical poles 1 and vertical and horizontal poles 3 connected to the building body 9, which can effectively support the casting formwork 8 and the balcony structure, and ensure the safety and stability during the casting process of the cantilever beam 11.

[0063] like Figure 4 As shown, in a preferred embodiment, the construction formwork of the cantilever beam 11 includes a supporting beam 7, the supporting beam 7 includes a plurality of cantilevered main beams 701, the cantilevered main beams 701 include a connecting portion connected to the building body 9 and a supporting portion extending out of the building body 9 for supporting the formwork bracket, and a height adjusting member 702 is provided at the bottom of the connecting portion, and the height adjusting member 702 is used to raise the height of the cantilevered main beam 701 so that the bottom elevation of the supporting portion is not lower than the top elevation of the balcony inverted beam.

[0064] During the construction of the support beam 7, the connection point between the connection part of the cantilever main beam 701 and the building main body 9 is first determined, and the height adjustment member 702 is installed at the connection point. The height of the cantilever main beam 701 is adjusted by selecting the height adjustment member 702 of appropriate height, so that the top elevation of the height adjustment member 702 is higher than the top elevation of the balcony inverted beam, thereby making the bottom elevation of the support part higher than the top elevation of the balcony inverted beam, and then the connection part and the building main body 9 are firmly connected. At this time, the height of the cantilever main beam 701 is adjusted in place, and its support part also stably extends out of the building main body 9, providing solid support for the casting formwork 8.

[0065] In this embodiment, the support beam 7 effectively solves the problem of balcony structure damage in the traditional construction method by setting a cantilever main beam 701 and a height adjustment member 702. The height of the cantilever main beam 701 is adjusted by the height adjustment member 702, so that the bottom elevation of the support part is not lower than the top elevation of the balcony inverted beam, thereby avoiding the direct pressure of the casting formwork 8, the formwork support and the concrete slurry on the balcony structure, which not only ensures the quality of the casting of the cantilever beam 11, but also ensures the safety and stability of the balcony structure. During the construction process, the structure is easy to install, flexible to adjust, and has high stability, providing a safer and more reliable support solution for the construction of the cantilever beam 11. In addition, the support beam 7 can be reused, which makes the construction cost low.

[0066] like Figure 4 As shown, in a preferred embodiment, the supporting portion of the cantilevered main beam 701 is provided with a longitudinal connecting beam 703, and the longitudinal connecting beam 703 is used to connect each cantilevered main beam 701 and support the formwork support.

[0067] During the construction process, the position of the cantilever main beam 701 is first determined according to the design, and the prefabricated longitudinal connecting beam 703 is connected to each cantilever main beam 701. When connecting, the horizontality and verticality of the longitudinal connecting beam 703 are adjusted to meet the requirements of the supporting formwork bracket. The connection can be made by using high-strength connectors or welding to ensure a firm and reliable connection. In this example, the vertical pole 1 is welded to the longitudinal connecting beam. After the connection is completed, the connection part is reinforced and protective measures are taken to ensure construction safety.

[0068] In this embodiment, the longitudinal connecting beam 703 is provided to connect the cantilevered main beam 701 and support the formwork support. The use of the longitudinal connecting beam 703 enhances the integrity between the cantilevered main beams 701 and improves the stability and bearing capacity of the structure. Secondly, through the support of the longitudinal connecting beam 703, the formwork support is more evenly stressed, thereby preventing deformation and damage of the formwork caused by uneven stress.

[0069] like Figure 4 As shown, in a preferred embodiment, a plurality of first connecting members 704 are provided on the connecting portion, and the first connecting members 704 penetrate the connecting support portion, the height adjusting member 702 and the floor of the building body 9 .

[0070] During the construction process, first, according to the support requirements of the support beam 7, the position of the connection point is pre-determined on the floor slab, so that the first connection members 704 can be reasonably distributed to stably support the cantilevered main beam 701. Subsequently, multiple first connection members 704 are arranged on the connection part, and the first connection members 704 can be made of high-strength materials to ensure the stability and safety of the connection. During installation, the first connection members 704 penetrate the floor slab connecting the support part, the height adjustment member 702 and the building body 9, and the first connection members 704 are ensured to be tightly combined with each part by welding, fastener connection or other reliable methods.

[0071] By arranging a plurality of first connectors 704 at the connection part, the connection between the cantilever main beam 701 and the building body 9 is made stable, effectively preventing structural deformation or damage caused by external loads, so that the casting formwork 8, the formwork support and the concrete slurry can be stably supported. Secondly, the connector runs through the support part, the height adjustment member 702 and the floor slab to form an integral structure, which enhances the rigidity and stability of the entire support beam 7, improves the safety during the construction process, and ensures the quality of the casting of the cantilever beam 11.

[0072] like Figure 4 As shown, in a preferred embodiment, a second connecting member 705 is provided on the supporting portion, and the second connecting member 705 connects the supporting portion and the upper cross beam of the building body 9.

[0073] During the construction process, the position and quantity of the second connector 705 are determined according to the design drawings, and are marked at appropriate positions of the support. Then, the second connector 705 is accurately installed on the support to ensure that the connector fits tightly with the support. Then, the other end of the second connector 705 is connected to the upper beam of the building body 9, usually by bolts, welding or other fastening methods.

[0074] In this embodiment, by providing a second connecting member 705 on the supporting part and connecting it to the upper cross beam of the building body 9, the connection strength between the supporting part and the building body 9 is enhanced, the stability and safety of the entire supporting structure are effectively improved, and it is able to resist the influence of external loads and vibrations, thereby ensuring the reliability and durability of the supporting beam 7 during use.

[0075] Specifically, Figure 4 As shown, the second connecting member 705 is a steel wire rope. By setting the steel wire rope as the second connecting member 705, the steel wire rope, as a high-strength, corrosion-resistant material, has excellent bearing capacity and durability, and can provide stable and reliable support for the formwork support, casting formwork 8, cantilever beam 11, etc.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
