Description

Technical Field

[0001] The invention relates to the field of formwork support structures, in particular to a formwork support structure for building construction. Background Art

[0002] The supporting structure is usually composed of a supporting frame and connecting pipe formwork panels. The supporting frame is the part that bears the main load, and common components include vertical poles, horizontal poles and other components made of materials such as steel pipes, wood or aluminum alloys; the connecting pipe 12 is used to connect the various supporting components into a whole, such as fasteners, bolts, etc.; the formwork panel is in direct contact with the newly poured concrete and plays a shaping role. During the concrete pouring process, it bears the lateral pressure and gravity of the newly poured concrete, as well as the loads generated during the construction process, such as the weight of construction workers, materials and equipment. For example, in the frame structure construction of high-rise buildings, the beam formwork can ensure that the shape and size of the beam meet the design requirements, and within a period of time after the concrete is poured, it ensures that the structure of the beam does not deform or displace before reaching a certain strength;

[0003] However, most existing support structures can only support single-sided structures. When fixing L-shaped structure templates such as stair joints and wall joints, multiple support structures are required for fixing, and the connection between the two templates is fixed by covering them with fixings or nails, which is too inconvenient. Summary of the Invention

[0004] The present invention provides a template support structure for building construction, which overcomes the shortcomings described in the background art.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A formwork support structure for construction, wherein an abutment portion is movably mounted on the upper end of a shaped member, and a threaded support member is passed through the shaped member so that the abutment portion is supported on the formwork surface after the threaded support member passes through the shaped member;

[0007] The I-shaped part includes an upper plate, a lower plate and a connecting pipe. The upper plate and the lower plate are connected by the connecting pipe. A reinforcement is provided in the connecting pipe, and the reinforcement is movably installed in the connecting pipe.

[0008] The abutment portion includes a movable abutment plate, which includes a abutment plate body and telescopic columns symmetrically arranged on the left and right sides of the lower end of the abutment plate body. The abutment plate body is fixed to the I-shaped piece by the telescopic columns arranged on the left and right sides. Through holes for passing bolts are respectively provided on both sides of the abutment plate body.

[0009] The threaded support member includes a threaded pipe, and the upper plate and the lower plate are both provided with a threaded hole. The threaded pipe passes through the two threaded holes from bottom to top, and the threaded pipe is threadedly connected to the threaded hole.

[0010] The telescopic column includes a hollow tube and a connecting rod. The hollow tubes are respectively arranged at both ends of the connecting rod. Springs are provided in the two hollow tubes. The two ends of the springs are respectively against the connecting rod and the corresponding hollow tube. The hollow tube located on the lower side is connected to the upper plate through a connecting shaft.

[0011] A better technical solution is that the threaded tube passes through the two threaded holes from bottom to top and then is pressed against the positioning groove set on the surface of the plate body. When the threaded tube pushes the plate body upward, the corresponding springs in the two hollow tubes are stretched through the hollow tubes on both sides.

[0012] A preferred technical solution, the abutment portion includes movable abutment plates symmetrically arranged on both sides of the upper end of the I-shaped part, and a threaded abutment tube 2 is arranged between the two movable abutment plates, and the threaded abutment tube 2 passes through the I-shaped part. When the two adjacent templates that are at an angle are supported by the two movable abutment plates, the two movable abutment plates respectively abut against the two templates, and the threaded abutment tube 2 passes through the I-shaped part and abuts at the connecting end of the two templates.

[0013] A preferred technical solution is that the connecting pipe is hollow, with openings on both sides of the connecting pipe, and a rotating adjustment piece is provided in the connecting pipe. The rotating adjustment piece protrudes from the surface of the connecting pipe through the openings provided on both sides of the connecting pipe. The second threaded pipe passes through the rotating adjustment piece, and the rotating adjustment piece is threadedly connected to the second threaded pipe. The outward extension length of the second threaded pipe can be adjusted by rotating the rotating adjustment piece.

[0014] There are angles between the second threaded abutment tube and the movable abutment plates on both sides.

[0015] A preferred technical solution is that the surface of the rotating adjustment member is arrayed with anti-slip strips and is provided with an inwardly recessed groove, and the connecting member is provided with a corresponding protrusion at the corresponding position of the groove, and the protrusion is embedded in the groove to form a limit for the rotating adjustment member, and the rotating adjustment member is provided with two threaded holes extending to the upper and lower ends, and the threaded pipe second pipe passes through the threaded hole second and forms a threaded connection with the threaded hole second;

[0016] The surface of the threaded tube is provided with a limiting groove extending along the length direction of the threaded tube, and the I-shaped part is provided with a through hole for the threaded tube to pass through. The corresponding parts of the through hole and the limiting groove are provided with a protruding block protruding outward, and the protrusion is inserted into the limiting groove to adjust the length of the threaded tube extending out of the through hole by rotating the adjusting part.

[0017] A preferred technical solution is that a strip-shaped abutment rod is provided at the upper end of the second threaded abutment tube. The strip-shaped abutment rod has a long strip structure, and a plurality of spikes are arranged in an array in the extension direction of the surface of the strip-shaped abutment rod. The spikes are arranged upwardly and each spike has an angle with the surface of the strip-shaped abutment rod. The second threaded abutment tube can be extended outward by rotating the rotating adjustment piece until the spikes abut against the connecting ends of the two templates. The rotating adjustment piece can then be continued to be rotated so that the spikes arranged on the surface of the strip-shaped abutment rod are inserted into the template for fixation.

[0018] Compared with the existing technology, this technical solution has the following advantages:

[0019] Through the cooperation of a movable abutment plate and a threaded abutment tube 1, efficient support of a single-sided formwork can be achieved. It has a simple structure and is easy to operate. It can quickly meet the support needs of a single-sided formwork and has strong adaptability. It can cope with formworks of different thicknesses. At the same time, the design of the I-shaped parts and the threaded connection ensures the stability of the support. It can also achieve multi-point support and fixation of two adjacent formworks that are at an angle to each other through the cooperation of two movable abutment plates and a threaded abutment tube 2, effectively preventing deformation or displacement of the formwork. Its design has strong adaptability and flexibility, and can adapt to L-shaped structure formworks with different angles. The extension length of the threaded abutment tube 2 can be adjusted by rotating the adjustment piece, which is easy to operate and further enhances the fixing effect of the formwork connection end.

[0034] Limiting groove 41 , strip-shaped abutting rod 42 , and spike 421 . DETAILED DESCRIPTION Example 1

[0035] like Figure 1 As shown, the present invention proposes a formwork support structure for construction, comprising an I-shaped member 1 and an abutment portion, wherein the abutment portion is movably mounted on the upper end of the I-shaped member 1, and a threaded support member is passed through the I-shaped member 1, so that the threaded support member passes through the I-shaped member 1 and supports the abutment portion on the formwork surface;

[0036] The I-shaped part 1 includes an upper plate, a lower plate and a connecting pipe 12. The upper plate and the lower plate are connected by the connecting pipe 12. A reinforcement is provided in the connecting pipe 12, and the reinforcement is movably installed in the connecting pipe 12; the abutting part includes a movable abutment 2, and the movable abutment 2 includes a abutment body 21 and telescopic columns 22 symmetrically arranged on the left and right sides of the lower end of the abutment body 21. The abutment body 21 is fixed to the I-shaped part 1 by the telescopic columns 22 arranged on the left and right sides. Through holes 212 for passing bolts are respectively provided on both sides of the abutment body 21.

[0037] Among them, the threaded support member includes a threaded abutment tube 3, and both the upper plate and the lower plate are provided with a threaded hole 11. The threaded abutment tube 3 passes through the two threaded holes 11 from bottom to top and then abuts against the positioning groove 211 provided on the surface of the abutment plate body 21, and the threaded abutment tube 3 and the threaded hole 11 are threadedly connected; the telescopic column 22 includes a hollow tube 221 and a connecting rod 222, and the hollow tubes 221 are respectively provided at both ends of the connecting rod 222. Springs 223 are provided in the two hollow tubes 221, and the two ends of the spring 223 are respectively abutted against the connecting rod 222 and the corresponding hollow tube 221. The hollow tube 221 located on the lower side is connected to the upper plate through a connecting shaft 224.

[0038] A preferred technical solution is that when the plate body 21 is pushed upward, the corresponding springs 223 in the two hollow tubes 221 are stretched through the hollow tubes 221 on both sides.

[0039] In construction, for formwork that requires single-sided support, such as some simple wall formwork or beam formwork, the structure of the present invention can provide a more convenient and stable support method. The I-shaped part 1 is placed at a suitable position below the formwork, and its lower plate is in contact with the ground to play a supporting and stabilizing role. The threaded pipe 3 is screwed into the threaded hole 11 of the lower plate. As the threaded pipe 3 is screwed in, its upper end will be against the positioning groove 211 on the surface of the plate body 21. By rotating the threaded pipe 3, the mechanical force of the thread is utilized. The threaded push tube 3 moves upward in the threaded hole 11, thereby pushing the push plate body 21 to move upward. The push plate body 21 is fixed to the I-shaped part 1 through the telescopic column 22. The spring 223 in the telescopic column 22 will be compressed as the push plate body 21 rises. When the push plate body 21 rises to contact and tightly abut the template surface, the threaded push tube 3 stops rotating. At this time, the I-shaped part 1, the threaded push tube 3 and the push plate body 21 work together to form a stable support structure to support one side of the template.

[0040] Compared to existing methods that require multiple supporting structures and cover the joints of two formwork panels with fixings or nails, the present invention supports single-sided formwork with a single I-shaped member 1, a threaded abutment tube 3, and a single abutment portion (a movable abutment plate 2). During operation, the height of the abutment plate 21 can be adjusted simply by rotating the threaded abutment tube 3, ensuring that the abutment plate 21 fits snugly against the formwork surface. This significantly simplifies the process and improves construction efficiency. Example 2

[0041] like Figure 2-Figure 10 As shown, the abutment portion includes movable abutment plates 2 symmetrically arranged on both sides of the upper end of the I-shaped member 1, and a threaded abutment tube 4 is arranged between the two movable abutment plates 2, and the threaded abutment tube 4 passes through the I-shaped member 1. When the two adjacent templates that are at an angle are supported by the two movable abutment plates 2, the two movable abutment plates 2 are respectively abutted against the two templates, and the threaded abutment tube 4 passes through the I-shaped member 1 and abuts at the connection end of the two templates.

[0042] A preferred technical solution is that the connecting tube 12 is hollow, with openings on both sides of the connecting tube 12, and a rotating adjustment member 13 is provided in the connecting tube 12. The rotating adjustment member 13 protrudes from the surface of the connecting tube 12 through the openings provided on both sides of the connecting tube 12, and the threaded pipe 4 passes through the rotating adjustment member 13. The rotating adjustment member 13 is threadedly connected to the threaded pipe 4, and the outward extension length of the threaded pipe 4 can be adjusted by rotating the rotating adjustment member 13;

[0043] There is an included angle between the threaded abutment tube 2 4 and the movable abutment plates 2 on both sides.

[0044] When in use, the I-shaped part 1 is placed below the connection of two adjacent templates that are at an angle to each other, so that the upper plate of the I-shaped part 1 is located below the connection ends of the two templates. By adjusting the length of the telescopic column 22, the two movable abutment plates 2 are tightly fitted with the sides of the two templates, respectively, to initially support the two templates. This preliminary support method provides a basis for subsequent fixation, ensuring that the template will not undergo large displacement during subsequent operations, and the outward extension length of the threaded abutment tube 2 4 is adjusted by rotating the rotary adjustment member 13. After the end of the threaded abutment tube 2 4 contacts the connection ends of the two templates, continue to rotate the rotary adjustment member 13 so that the threaded abutment tube 2 4 gradually applies pressure to the connection ends of the two templates until the threaded abutment tube 2 4 firmly rests on the connection ends of the two templates. This fixing method utilizes the threaded connection between the threaded abutment tube 2 4 and the rotary adjustment member 13 to achieve precise fixation through mechanical principles, ensuring that the connection ends of the two templates are tightly fixed to prevent deformation or displacement during the concrete pouring process.

[0045] Two movable abutment plates 2 support the two formworks separately, while threaded abutment tubes 2 secure the connecting ends of the two formworks. This multi-point support and fixation method ensures more stable support for the formwork against the lateral pressure and gravity generated by concrete pouring, as well as the loads generated during construction. Compared to existing support structures that can only support single-sided structures, this invention effectively solves the problem of inconvenient support for L-shaped formwork, providing a more stable and reliable support solution.

[0046] Furthermore, an angle exists between the threaded abutment tube 2 and the movable abutment plates 2 on either side. This design allows the threaded abutment tube 2 to better adapt to the angle between the two templates. Regardless of how the angle changes, the threaded abutment tube 2 can adjust its extension length to securely abut the connecting ends of the two templates. This adaptable design allows the present invention to be applied to L-shaped templates with different angles, providing strong versatility and adaptability.

[0047] The surface of the rotating adjustment member 13 is arrayed with anti-slip strips 131 and is provided with an inwardly recessed slot 132. The connecting member is provided with a corresponding protrusion at the corresponding position of the slot 132. The protrusion is embedded in the slot 132 to limit the rotation of the adjusting member 13. The rotating adjustment member 13 is provided with a second threaded hole 133 extending to the upper and lower ends. The threaded pipe 4 passes through the second threaded hole 133 and forms a threaded connection with the second threaded hole 133.

[0048] The surface of the threaded abutment tube 2 4 is provided with a limiting groove 41 extending along the length direction of the threaded abutment tube 2 4, and a through hole 14 for the threaded abutment tube 2 4 to pass through is provided in the I-shaped part 1, and the corresponding positions of the through hole 14 and the limiting groove 41 are provided with outwardly protruding bumps 141, which are inserted into the limiting groove 41 so as to adjust the length of the threaded abutment tube 2 4 extending out of the through hole 14 by rotating the adjusting member 13.

[0049] When securing the I-shaped member using the support structure of this embodiment, ensure that the I-shaped member 1 is properly positioned below the junction of the two adjacent, angled templates, and that the two movable abutment plates 2 have been adjusted to a position that closely fits the sides of the two templates using the telescopic function of the telescopic columns 22. Check that the second threaded abutment tube 4 has properly passed through the second threaded hole 133 of the rotary adjustment member 13, and that the retaining groove 41 of the second threaded abutment tube 4 is properly engaged with the protrusion 141 in the I-shaped member 1, to ensure that the second threaded abutment tube 4 can move smoothly during adjustment.

[0050] Furthermore, a strip-shaped abutment rod 42 is provided at the upper end of the threaded abutment tube 4. The strip-shaped abutment rod 42 is in an elongated structure, and a plurality of spikes 421 are arranged in an array along the extension direction of the surface of the strip-shaped abutment rod 42. The spikes 421 are arranged obliquely upward, and each spike 421 forms an angle with the surface of the strip-shaped abutment rod 42. The threaded abutment tube 4 can be extended outward by rotating the rotary adjustment member 13 until the spikes 421 abut against the connecting ends of the two templates. The rotary adjustment member 13 can then be further rotated to insert the spikes 421 provided on the surface of the strip-shaped abutment rod 42 into the template for fixation. According to the method described above, the threaded abutment tube 4 can be extended outward by rotating the rotary adjustment member 13 until the spikes 421 of the strip-shaped abutment rod 42 abut against the connecting ends of the two templates. This process requires careful observation of the contact between the spikes 421 and the template to ensure that the spikes 421 can evenly abut or penetrate the template surface to form a fixed position. When the spikes 421 abut the connecting ends of the two templates, continue to rotate the rotary adjustment member 13. Since the spikes 421 are set upward at an angle, and each spike 421 has an angle with the surface of the strip-shaped abutment rod 42, continuing to rotate the rotary adjustment member 13 will cause the threaded abutment tube 24 to extend further outward, thereby pushing the spikes 421 into the template. This plug-in fixing method can more firmly fix the connecting ends of the two templates together, preventing the template from deformation or displacement during the concrete pouring process.

[0051] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of the present invention. In other words, equivalent changes and modifications made according to the scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
