Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a formwork support frame with a non-orthogonal irregular structure. Background Technology

[0002] The construction process of non-orthogonal structural systems is more complex than that of traditional orthogonal structural systems, requiring higher levels of engineering technology and building materials. The uncertainty of construction and the risks to engineering safety also increase the difficulty of construction.

[0003] Traditional formwork erection methods typically use disc-lock scaffolding. When the cross-section of the skew beam is large, additional uprights must be added. This often results in a scattered arrangement of formwork on site, easily leading to a mix of disc-lock scaffolding and other fasteners. Erecting a single layer of formwork requires six days. For non-orthogonal, complex irregular structures, the uprights at the bottom of skew beams are prone to eccentric stress or not forming a cohesive unit with the surrounding scaffolding, resulting in poor scaffold stability. This leads to lengthy rectification periods, low construction efficiency, and significant safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a formwork support frame for non-orthogonal irregular structures, so as to solve the technical problem of poor frame stability when using formwork supports to construct non-orthogonal structural systems in the prior art. The specific technical solution is as follows:

[0005] This utility model provides a formwork support frame with a non-orthogonal irregular structure, including a vertical support mechanism, a lifting mechanism and a diagonal bracing mechanism;

[0006] The vertical support mechanism includes a vertical pole assembly, a horizontal bar assembly, and a diagonal bar assembly. The vertical pole assembly is used to support the floor slab formwork. The horizontal bar assembly is detachably connected to the vertical pole assembly. The diagonal bar assembly is detachably connected between the horizontal bar assembly and the vertical pole assembly.

[0007] The lifting mechanism includes a support beam and a telescopic upright. The two ends of the support beam are height-adjustably connected to the upright assembly. The bottom of the telescopic upright is movably mounted on the support beam, and the top of the telescopic upright is used to support the bottom template of the beam.

[0008] The diagonal bracing mechanism includes a first diagonal brace, the first end of which is used to support the beam side formwork, and the second end of which is movably connected to the upright assembly.

[0009] A further improvement of the non-orthogonal irregular structure formwork support frame of this utility model is that the diagonal bracing mechanism further includes a second diagonal brace, the first end of which is used to support the beam side formwork, and the second end of which is movably connected to the upright assembly.

[0010] A further improvement of this utility model's non-orthogonal irregular structure formwork support is that the second diagonal brace is used to vertically connect to the side formwork of the beam.

[0011] A further improvement of the non-orthogonal irregular structure formwork support frame of this utility model is that the second end of the first diagonal brace and the second end of the second diagonal brace are connected to the upright assembly through the first spherical locking assembly, and the first end of the first diagonal brace and the first end of the second diagonal brace are respectively connected to the beam side formwork through the second spherical locking assembly.

[0012] A further improvement of the non-orthogonal irregular structure formwork support frame of this utility model is that the upright assembly includes multiple supporting uprights and at least two adjustable uprights, with at least two adjustable uprights located around the beam body, and multiple supporting uprights located around the at least two adjustable uprights. The diagonal brace assembly is connected between the adjustable uprights and the crossbar assembly.

[0013] A further improvement of the non-orthogonal irregular structure formwork support frame of this utility model is that the inclined rod assembly includes multiple supporting inclined rods and at least two adjustable inclined rods. The adjustable inclined rods are connected between the adjustable upright and the horizontal rod assembly, and the supporting inclined rods are connected between the adjustable upright and the horizontal rod assembly or between the supporting upright and the horizontal rod assembly.

[0014] A further improvement of the non-orthogonal irregular structure formwork support frame of this utility model is that the top of the supporting upright, the adjustable upright and the telescopic upright are all provided with a top support, and the first end of the first diagonal brace and the first end of the second diagonal brace are also provided with the top support.

[0015] A further improvement of this utility model's non-orthogonal irregular structure formwork support frame is that the support beam is concave, and the telescopic upright is movably installed in the middle of the support beam.

[0016] The application of the technical solution of this utility model has the following beneficial effects:

[0017] This utility model relates to a non-orthogonal irregular structure formwork support frame. Through telescopic uprights movably mounted on the support beams, the uprights can be adjusted to align with the center point under the beam, ensuring the beam bottom bears the load centrally. Furthermore, through a first diagonal brace movably connected to the upright assembly, the first diagonal brace can be adjusted to align with the center point on the side of the beam, ensuring the beam bottom bears the load centrally. The frame exhibits good overall integrity and stable stress distribution, solving the technical problem of poor frame stability in existing formswork support frames used for non-orthogonal structural system construction.

[0018] This utility model addresses non-orthogonal structural systems. By installing support beams under individual secondary beams, the erection of ground-mounted uprights for the secondary beams can be eliminated. Only support beams need to be placed on the uprights on both sides of the beam, with telescopic uprights installed within the support beams. This saves material input, speeds up construction, and is suitable for the formwork erection of all large-span, large-space, and high-rise non-orthogonal structural system projects. During the main structure construction phase, the formwork system adopts a disc-lock scaffold plus double support beam system, which offers high construction efficiency, simple erection, and good concrete forming quality after demolding.

[0019] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0026] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] In this embodiment, the template includes a floor slab template 17, beam side templates 18, and beam bottom templates 19. During pouring, the floor slab template 17, beam side templates 18, and beam bottom templates 19 are combined to form a pouring space for pouring the floor slab 8 and the beam 9 (see [link]). Figure 2 and Figure 3 ).

[0028] See Figures 1-4 As shown, a non-orthogonal irregular-shaped formwork support frame includes a vertical support mechanism, a lifting mechanism, and an inclined bracing mechanism;

[0029] The vertical support mechanism includes a vertical pole assembly, a horizontal bar assembly, and a diagonal bar assembly. The vertical pole assembly is used to support the floor slab formwork 17. The horizontal bar assembly is detachably connected to the vertical pole assembly. The diagonal bar assembly is detachably connected between the horizontal bar assembly and the vertical pole assembly.

[0030] The lifting mechanism includes a support beam 5 and a telescopic upright 4. The two ends of the support beam 5 are height-adjustably connected to the upright assembly. The bottom of the telescopic upright 4 is movably installed on the support beam 5, and the top of the telescopic upright 4 is used to support the bottom template of the beam.

[0031] The diagonal bracing mechanism includes a first diagonal brace 15, the first end of which is used to support the beam side formwork 18, and the second end of which is movably connected to the upright assembly.

[0032] Specifically, since both ends of the support beam 5 are height-adjustable to the upright assembly, the height of the support beam 5 can be adjusted to accommodate different beam heights 9, thus improving the flexibility of the formwork support. This height-adjustable and movable connection method can be achieved using existing scaffolding clips or clamp structures. The telescopic upright 4 can be length-adjusted using a screw structure or a combination of a male and female rod and a pin.

[0033] Preferably, the diagonal bracing mechanism further includes a second diagonal brace 16, the first end of which is used to support the beam side formwork 19, and the second end of which is movably connected to the upright assembly. By adjusting the positions of the first diagonal brace 15 and the second diagonal brace 16 on the upright assembly, the support angle of the beam side formwork 18 is adjusted, thereby adjusting the support force, so that the beam side formwork 18 is stably supported and maintains force balance.

[0034] Preferably, the second diagonal brace 16 is used for vertical connection to the beam side formwork 18. Vertical connection allows the vertical support force of the second diagonal brace 16 to be fully applied to the beam side formwork 18, while at other angles, the support force provided by the second diagonal brace 16 will not be fully transmitted to the beam side formwork 18, thus affecting the magnitude of the support force.

[0035] Preferably, the second end of the first diagonal brace 15 and the second end of the second diagonal brace 16 are connected to the upright assembly through the first spherical locking assembly 11. The first end of the first diagonal brace 15 and the first end of the second diagonal brace 16 are respectively connected to the beam side formwork 18 through the second spherical locking assembly, so that the first diagonal brace 15 and the second diagonal brace 16 are set at an angle, thereby increasing the support area of ​​the beam side formwork 18 and making the beam side formwork 18 stably supported.

[0036] Specifically, the first spherical locking assembly 11 includes a fixed ball, multiple pins 3, and multiple fastening nuts. The pins adopt a screw structure. Multiple openings for the pins 3 to be inserted are respectively provided on the fixed ball, the first diagonal support rod 15, the second diagonal support rod 16, and the adjustable upright rod 1. When two pins 3 are simultaneously inserted into the fixed ball and the adjustable upright rod 1, and then two more pins are simultaneously inserted into the fixed ball and the first diagonal support rod 15, and the fastening nuts are used to tighten each pin 3, the position of the first diagonal support rod 15 on the adjustable upright rod 1 can be fixed. Figure 4 As shown, the first diagonal brace 15 is offset from the center of the fixed ball by 3cm. When it is necessary to connect the second diagonal brace 16 at the same time, two additional pins 3 are used to insert and fix the second diagonal brace 16 to the fixed ball. The structure of the second spherical locking assembly is the same as that of the first spherical locking assembly 11. A connecting rod is provided on the back of the beam side formwork 18, and an opening for the pins 3 to be inserted is also provided on the connecting rod. The beam side formwork 18 and the second diagonal brace 16 can be fixed by inserting one or two pins 3 simultaneously into the connecting rod, the fixed ball and the second diagonal brace 16. The first diagonal brace 15 can be fixed in the same way. The angle between the adjustable upright 1 and the first diagonal brace 15 in the plane can be customized according to the angle in the actual project. The position of the opening for the pins 3 can be calculated according to the specific actual needs.

[0037] Preferably, the upright assembly includes multiple supporting uprights 7 and at least two adjustable uprights 1. The at least two adjustable uprights 1 are located around the beam 9, and the multiple supporting uprights 7 are located around the at least two adjustable uprights 1. The diagonal brace assembly connects the adjustable uprights 1 and the horizontal brace assembly. Specifically, the adjustable upright 1 includes an adjusting section 14 and a non-adjustable section 14 connected along its length. The adjusting section 14 can be adjusted in length using a screw structure or a pin-and-groove structure. The entire length of the adjustable upright 1 can be adjusted by adjusting the length of the adjusting section 14, thereby adapting to the support of floor slab formwork 17 at different heights. During construction, supporting uprights 7 of different lengths can be used for support at floor slabs 8 at different heights. In areas with variable heights, the supporting uprights 7 can be replaced with adjustable uprights 1. The horizontal brace assembly includes multiple supporting horizontal bars 6 spaced apart and connected to the supporting uprights 7 and / or the adjustable uprights 1.

[0038] Preferably, the diagonal brace assembly includes multiple supporting diagonal braces 12 and at least two adjustable diagonal braces 13. The adjustable diagonal braces 13 are connected between the adjustable upright 1 and the crossbar assembly, and the supporting diagonal braces 12 are connected between the adjustable upright 1 and the crossbar assembly, or between the supporting upright 7 and the crossbar assembly. The adjustable diagonal braces 13 can also be adjusted in length using a screw structure or a nut-and-pin structure. The adjustable diagonal braces 13 can provide tension to the support beam 5 to ensure the stability of the structure.

[0039] Preferably, the top of the supporting upright 7, the adjustable upright 1, and the telescopic upright 4 are all provided with top supports 2, and the first end of the first diagonal brace 15 and the first end of the second diagonal brace 16 are also provided with top supports 2. The top supports 2 can directly support the formwork, increasing the contact area with the formwork, thereby increasing the stress area and improving the stability of the entire formwork support. Furthermore, the top supports 2 support the formwork, while multiple spacers 10 are spaced apart between the formwork and the reinforced concrete structure.

[0040] Preferably, the support beam 5 is concave, and the telescopic upright 4 is movably installed in the middle of the support beam 5. In this embodiment, there are two telescopic uprights 4, which are movably and spaced apart in the middle of the support beam 5. By moving the two telescopic uprights 4 left and right on the support beam 5, different beam widths 9 can be accommodated, thereby improving the flexibility of the entire formwork support. The concave support beam 5 provides support for the telescopic uprights 4 and concentrates both ends of the support beam 5 and the second annular locking member at the adjustment section, thereby achieving simultaneous height adjustment, saving adjustment operation steps, and facilitating installation.

[0041] The top surface of a non-orthogonal irregular structure includes main beams, inclined secondary beams, and floor slabs. For example... Figure 2 As shown, when arranging the uprights of the main beam, taking a 600mm×1300mm beam section as an example, according to the calculation results, two additional uprights are required at the bottom of the main beam compared to the inclined secondary beam. The spacing along the length of the main beam is 900mm. The distance between the uprights on the floor slabs on both sides of the main beam must be greater than or equal to 250mm on both sides of the beam, and they should be arranged parallel to the direction of the main beam.

[0042] like Figure 3 As shown, when arranging the upright components of the inclined secondary beam, taking a 400mm×1100mm beam section as an example, the support beam 5 is used instead of the bottom support upright components of the beam. The spacing along the beam length direction is 1200mm. This is applicable to all beam types 9 with a line load of less than 17.4kN / m. The arrangement method is the same as that of the main beam.

[0043] When arranging the uprights for floor slab 8, taking a slab thickness of 180mm as an example, the calculation results show that the spacing between the uprights is 1200mm×900mm. The direction of the uprights for floor slab 8900mm is determined by the spacing of the uprights along the bottom of the main beam, and the direction of the uprights for floor slab 81200mm is determined by the spacing of the uprights along both sides of the inclined secondary beam.

[0044] When the formwork is erected, (1) 10 pads are laid along the length of the inclined secondary beam with a spacing of 11mm. The spacing of the formwork along the length of the inclined secondary beam is 900mm and the horizontal spacing is 1200mm. Two uprights are added to the bottom of the inclined secondary beam. Two A48.3×3.0 steel pipes are placed in the top support 2 with a spacing of 1200mm between the two steel pipes. The ground sweeping bar is no more than 550mm from the ground and the horizontal step distance is 1500mm. (2) It is applicable to beams with a beam line load ≤17.4kN / m and is applicable to the beam-slab upright common support system. According to the control line of the inclined secondary beam, the common plate uprights on both sides of the inclined secondary beam are erected first. Then the support beam 5 is connected to the upright assembly. By adjusting the left and right sliding of the top support 2 on the upper part of the support beam 5, the top support 2 is evenly distributed on the bottom of the inclined secondary beam to avoid eccentric force. Modular 600mm, 900mm, and 1200mm support crossbars 6 are used to tie the upright assembly, and the inclined secondary beam support system is formed. (3) For structural slabs with a thickness of 180mm~360mm, the calculation results show that the horizontal spacing of the uprights of the formwork support is 900mm, the longitudinal spacing is 1200mm, the 6-step spacing of the support crossbar is 1.5m, the template is 15mm thick large plywood, the specifications of the bottom pad of the template are 50mm×70mm, the spacing of the timber is 250mm, the ground sweeper is no more than 550mm from the ground, and the diagonal bracing is arranged every two spans in the longitudinal and transverse directions.

[0045] Furthermore, it is worth noting the reinforcement method for ultra-high (height greater than 8m) formwork: (1) Before the formwork is erected, the vertical structural columns are constructed in sections, each section being 2-3 meters long, with the construction reaching 100mm from the bottom of the structural beam 9 as the standard, leaving room for error to facilitate the subsequent laying of the bottom beam formwork 19. After the beam and slab formwork is erected, the frame is connected to the structural column by steel pipes and fasteners to reinforce the column and improve the stability of the frame. (2) The support uprights 7 of the formwork should use continuous steel pipes as much as possible, and protective buckles must be added at the intersection of the support uprights 7 and the formwork crossbars (at each location). (3) The camber size of the top slab formwork should be determined according to the beam span: <4m does not consider camber, 4m≥L>12m is cambered at 2‰ of the span, L≥12m is cambered at 3‰ of the span, and cantilevered components are cambered at 4‰ of the span.

[0046] This utility model relates to a non-orthogonal irregular structure formwork support frame. Through a telescopic upright 4 movably mounted on the support beam 5, the telescopic upright 4 can be adjusted to align with the center point under the beam, ensuring the beam bottom is centrally stressed. Through a first diagonal brace 15 movably connected to the upright assembly, the first diagonal brace 15 can be adjusted to align with the center point on the side of the beam, ensuring the beam bottom is centrally stressed. The frame has good overall integrity and stable stress distribution, solving the technical problem of poor frame stability in existing formswork support frames used for non-orthogonal structural system construction.

[0047] This utility model addresses non-orthogonal structural systems. By installing a support beam 5 under a single secondary beam, the erection of the secondary beam's supporting poles can be eliminated. Only the support beam 5 needs to be placed on the uprights on both sides of the beam, with telescopic uprights 4 installed within the support beam 5. This saves material input, speeds up construction, and is suitable for the formwork erection of all large-span, large-space, and high-rise non-orthogonal structural system projects. During the main structure construction phase, the formwork system adopts a disc-lock scaffold plus double support beam 5 system, which has high construction efficiency, is simple to erect, and results in good concrete forming quality after demolding.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
