Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of disc buckle frame construction, and particularly relates to a disc buckle frame formwork method for overhanging position. BACKGROUND

[0002] The existing disc buckle frame (disc buckle scaffold) has a fixed module number. When the formwork is set for the overhanging position of a building, the disc buckle frame often exceeds the overhanging position, which hinders the erection of the outer frame outside the overhanging position after the construction of the overhanging position is completed. On the other hand, when the overhanging position of the building has a protruding structure, the disc buckle frame with a fixed module number is not convenient to adjust the position of the rod during the construction process according to the position of the protruding structure, which causes the load distributed on the rod to be uneven during the formwork process for the protruding structure, which not only causes the deformation and damage of the rod at the stress concentration position, but also causes the formwork to loosen and the concrete to leak. SUMMARY

[0003] The disc buckle frame formwork method for overhanging position provided by the embodiments of the present application can set the construction structure of the disc buckle frame according to the structure of the overhanging position, so that the formwork structure is more stable and does not hinder the erection of the outer frame outside the overhanging position.

[0004] A disc buckle frame formwork method for overhanging position, comprising:

[0005] constructing a structure model of the overhanging position according to construction drawings;

[0006] setting a virtual boundary outside the structure model of the overhanging position;

[0007] identifying the formwork surface in the structure model of the overhanging position, and identifying the protruding structure in the structure by using the formwork surface;

[0008] generating the construction structure of the disc buckle frame according to the identification result and the set virtual boundary.

[0009] Further, the step of identifying the protruding structure in the structure of the overhanging position by using the formwork surface is as follows:

[0010] obtaining all orthographic projection planes of the structure model of the overhanging position in the formwork direction;

[0011] identifying the elevation values of the orthographic projection planes;

[0012] identifying the elevation distribution of the orthographic projection planes by using the elevation values, and identifying the protruding structure existing in the formwork surface.

[0013] Further, the non-protruding formwork surface is defined as a reference surface, the protruding formwork surface is defined as an adjustment surface, and the step of generating the construction structure of the disc buckle frame is as follows:

[0014] Calculate the load distribution of the reference surface and the adjustment surface;

[0015] According to the load distribution and the module of the disc buckle frame, arrange the erection structure of the disc buckle frame under the reference surface and the adjustment surface;

[0016] Identify the module abnormal horizontal rod in the erection structure of the disc buckle frame;

[0017] Replace the module abnormal horizontal rod with the telescopic horizontal rod;

[0018] Perform stress analysis on the erection structure of the disc buckle frame, and output the erection structure parameters of the disc buckle frame when the stress meets the requirements.

[0019] Further, after replacing the module abnormal horizontal rod with the telescopic horizontal rod, the following steps are further included:

[0020] Identify whether the telescopic horizontal rod is a force-bearing rod;

[0021] If it is not a force-bearing rod, perform stress analysis, and output the erection structure parameters of the disc buckle frame when the stress meets the requirements;

[0022] If it is a force-bearing rod, calculate the load it bears, and evaluate the reliability of the current telescopic horizontal rod. If the reliability does not meet the requirements, introduce a telescopic support to support the telescopic horizontal rod;

[0023] After performing stress analysis, output the erection structure parameters of the disc buckle frame when the stress meets the requirements.

[0024] Further, evaluating the reliability of the telescopic horizontal rod includes the following steps:

[0025] Identify the length of the telescopic horizontal rod after replacing the telescopic horizontal rod;

[0026] According to the length and parameters of the telescopic horizontal rod, calculate the load extreme value it can bear;

[0027] Set a safety threshold using the above load. If the load borne by the telescopic horizontal rod calculated exceeds the safety threshold, it is determined that the reliability does not meet the requirements.

[0028] Further, if the erection structure of the disc buckle frame exceeds the virtual boundary, optimize the structure that exceeds the virtual boundary, so that the erection structure of the disc buckle frame is located within the range of the normal projection face of the structure model in the cantilever position.

[0029] Further, the telescopic horizontal rod includes a telescopic segment a, a telescopic segment b, and a telescopic segment c. The two ends of the telescopic segment b are respectively threadedly connected with the telescopic segment b and the telescopic segment c. The telescopic segment a and the telescopic segment c are used to connect with the disc buckle on the vertical rod of the disc buckle frame.

[0030] Further, the telescopic support comprises a support base connected to the middle part of the telescopic section b, and one end of the telescopic rod a and the telescopic rod b are respectively hinged to the bottom of the support base, and the other end of the telescopic rod a and the telescopic rod b are connected to the vertical rod through the clamp.

[0031] Further, the radial load application point of the telescopic horizontal rod is arranged at the middle part of the telescopic section b or simultaneously arranged at the middle part of the telescopic section a and the telescopic section c.

[0032] Further, if the telescopic horizontal rod is a bearing rod, and the support stress of the telescopic horizontal rod supported by the telescopic support cannot meet the demand, the span between the disc buckle frame vertical rod connected to the telescopic horizontal rod is adjusted, so that the stress of the telescopic horizontal rod meets the demand.

[0033] The beneficial effects of the above technical solutions provided by the embodiments of the present application at least include:

[0034] 1. By identifying the boundary of the overhanging position of the building structure, and designing the disc buckle frame erection structure according to the structural model of the overhanging position, the finally erected disc buckle frame can not only meet the demand of formwork support stress, but also keep the disc buckle frame erection structure within the boundary of the overhanging position, avoiding the influence on the erection of the outrigger outside the overhanging position.

[0035] 2. In the process of designing the disc buckle frame erection structure, the telescopic horizontal rod is used, and the telescopic characteristics of the telescopic horizontal rod are used to optimize the position of the rod according to the protruding structure of the overhanging position. Compared with the existing disc buckle frame with fixed modulus, the adjustment of the position of the rod is more flexible, which can avoid the damage of the rod caused by stress concentration due to uneven load distribution and the problem of slurry leakage caused by formwork loosening.

[0045] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be accurately conveyed to those skilled in the art.

[0046] Figure 1 A structural diagram of a building cantilevered position using a fixed modulus disc buckle frame in the prior art is shown, wherein the disc buckle frame, also known as a disc buckle 2 type scaffold, includes vertical rods 1, horizontal rods 6, disc buckles 2, wedge-shaped pins, etc. In the existing disc buckle frame, the modulus of the vertical rods 1 has specifications of 500mm, 1000mm, 1500mm, 2000mm, 2500mm, 3000mm, etc., and the modulus of the horizontal rods 6 has specifications of 1200mm, 1500mm, 1800mm, etc. During the building process of the disc buckle frame, different fixed modulus vertical rods 1, horizontal rods 6, disc buckles 2, wedge-shaped pins, etc. are selected for building.

[0047] The wedge-shaped pin is used to fix the position of the horizontal rod 6 and the disc buckle 2 after the horizontal rod 6 and the disc buckle 2 are connected.

[0048] During the building process, although different specifications of rod members can be used for building due to the fixed modulus, abnormalities may still occur during the building process, such as Figure 1As shown, when the horizontal rod 6 with a fixed module is adopted, the structure of the disc buckle frame exceeds the edge of the overhanging position, so that the completed disc buckle frame will hinder the erection of the outer frame outside the overhanging position, and affect the subsequent construction, and as shown, when the overhanging structure has a protruding structure, when supporting the protruding structure, due to the adoption of the horizontal rod 6 with a fixed module, the load borne by the horizontal rod 6 during the supporting process will be deviated to one side, thereby causing stress concentration, causing the rod at the stress concentration position to be deformed and damaged, and causing the formwork to be loose and the problem of slurry leakage.

[0049] As Figure 2 shown, in order to solve the above problems, the present application provides a disc buckle frame formwork supporting method for an overhanging position.

[0050] It comprises the following steps:

[0051] S1, constructing a structure model of the overhanging position according to the construction drawings.

[0052] The commonly used BIM software includes Revit, Navisworks, Bentley Navigator, ArchiCAD, etc., and the appropriate software is selected according to the project requirements and the team's familiarity to construct the structure model of the building overhanging position, and the above-mentioned model construction process adopts the prior art, and the specific construction process is not described here.

[0053] S2, setting a virtual boundary on the outer side of the structure model of the overhanging position.

[0054] It comprises the following steps:

[0055] S21, importing the above-mentioned structure model of the overhanging position;

[0056] S22, identifying the end face of the overhanging end (the side away from the building);

[0057] S23, taking out the outermost end face;

[0058] S24, constructing a virtual boundary by using the end face.

[0059] S3, identifying the formwork surface in the structure model of the overhanging position, and identifying the protruding structure in the structure by using the formwork surface.

[0060] The meaning of the above-mentioned formwork surface is the surface in contact with the disc buckle frame, which is used to set the formwork supported by the disc buckle frame.

[0061] In the process of identifying the protruding structure in the structure by using the formwork surface:

[0062] S31, obtaining all the orthographic projection surfaces of the structure model of the overhanging position in the formwork direction;

[0063] S32, identify the elevation values ​​of each orthographic projection plane;

[0064] S33. Using the above elevation values, the elevation distribution of the orthographic projection surface is identified, and the protruding structures existing on the formwork surface are identified.

[0065] The reference surface for the above elevation values ​​is the ground, where the elevation values ​​of the projected surface of the protruding structure are lower than the elevation values ​​of the projected surface of the non-protruding structure.

[0066] Among them, the non-protruding formwork surface is defined as the reference surface, and the protruding formwork surface is defined as the adjustment surface.

[0067] S4. Based on the above recognition results and the set virtual boundaries, generate the assembly structure of the disc buckle frame.

[0068] The steps for generating the assembly structure of the disc buckle frame are as follows:

[0069] S41, Based on the load distribution and the module of the disc buckle frame, arrange the mounting structure of the disc buckle frame below the reference plane and the adjustment plane;

[0070] S42, Identify the modularly abnormal horizontal bar 6 in the above-mentioned disc buckle frame construction structure;

[0071] The definition of a module abnormality is: the current total number of horizontal bars of module 6 cannot meet the usage requirements of the construction, such as being too long or too short.

[0072] like Figures 3-4 As shown, the telescopic horizontal bar 3 includes telescopic section a31, telescopic section b32 and telescopic section c33. The two ends of telescopic section b32 are threadedly connected to telescopic section b32 and telescopic section c33 respectively. Telescopic section a31 and telescopic section c33 are used to connect to the disc buckle 2 on the disc buckle frame upright 1.

[0073] The above embodiments are only one example of the telescopic horizontal bar 3. The connection of the above structure can also be configured as a plug-in type, that is, both ends of the telescopic section b32 are plugged into the telescopic section b32 and the telescopic section c33 respectively, and a buckle is provided to fix the position of the telescopic section b32 and the telescopic section c33. The buckle forms include:

[0074] 1. Threaded holes are provided on the radial sidewalls of telescopic sections a31 and c33, and hand-tightening screws are provided to be threaded into the threaded holes. The positions of telescopic sections a31 and c33 on telescopic section b32 are fixed by rotating the hand-tightening screws.

[0075] 2. Holes with the same diameter are made in the telescopic sections a31, b32 and c33. After the holes overlap, they are fixed with pins to fix the position of telescopic sections a31 and c33 on the telescopic section b32.

[0076] Through the above setting, the length of the telescopic horizontal rod 3 can be adjusted to achieve the effect of adjusting the modulus of the existing horizontal rod 6, and various protruding structures can be used according to different structures of the building cantilever structure.

[0077] In the process of building the disc mouth frame, the radial load application point of the telescopic horizontal rod 3 is arranged at the middle of the telescopic section b32 or at the middle of the telescopic section a31 and the telescopic section c33 at the same time, so as to realize the effect of uniformly dispersing the load and avoid the problem of deformation and damage of the rod caused by stress concentration.

[0078] In an embodiment, if the telescopic horizontal rod 3 is a load-bearing rod and the telescopic support 4 cannot meet the demand when supporting the telescopic horizontal rod 3, the span between the disc buckle frame stand rod 1 connected to the telescopic horizontal rod 3 is adjusted to make the telescopic horizontal rod 3 meet the demand.

[0079] S43, the telescopic horizontal rod 3 is introduced to replace the modulus abnormal horizontal rod 6;

[0080] After the telescopic horizontal rod 3 replaces the modulus abnormal horizontal rod 6, the following steps are further included:

[0081] S431, identifying whether the telescopic horizontal rod 3 is a load-bearing rod;

[0082] S432, if it is not a load-bearing rod, after stress analysis, the building structure parameters of the disc buckle frame are output when the stress meets the demand;

[0083] S433, if it is a load-bearing rod, the load it bears is calculated, and the reliability of the current telescopic horizontal rod 3 is evaluated, if the reliability does not meet the demand, the telescopic support 4 is introduced to support the telescopic horizontal rod 3;

[0084] S434, after stress analysis, the building structure parameters of the disc buckle frame are output when the stress meets the demand.

[0085] The above evaluation of the reliability of the telescopic horizontal rod 3 includes the following steps:

[0086] Identifying the length of the telescopic horizontal rod 3 after replacing the telescopic horizontal rod 3;

[0087] According to the length and parameters of the telescopic horizontal rod 3, the load extreme value it can bear is calculated;

[0088] A safety threshold is set using the above load, and when the load borne by the telescopic horizontal rod 3 calculated exceeds the safety threshold, it is judged that the reliability does not meet the demand.

[0089] The safety threshold can be set to 80%, 75%, 70% of the load extreme value, and the specific value can be set according to demand, preferably 80%.

[0090] S44, force analysis is performed on the building structure of the disc buckle frame, and the building structure parameters of the disc buckle frame are output when the force meets the requirements.

[0091] As shown in the figure, Figures 3-4 The telescopic support 4 includes a support seat 41 connected to the middle part of the telescopic section b32, one end of the telescopic rod a42 and the telescopic rod b43 are respectively hinged on both sides of the bottom of the support seat 41, and the other end of the telescopic rod a42 and the telescopic rod b43 are connected with the vertical rod 1 through the clamp 5.

[0092] According to the length of the telescopic horizontal rod 3, the expansion angle and length of the telescopic support 4 are adjusted, so that it is connected with the clamp 5 and installed on the vertical rod 1.

[0093] The present application can make the finally built disc buckle frame not only meet the requirements of formwork stress, but also keep the disc buckle frame building structure within the cantilever position boundary, avoid the influence on the erection of the outer frame outside the cantilever position, on the other hand, in the process of designing the disc buckle frame building structure, the telescopic horizontal rod 3 is used, and the position of the rod is optimized according to the protruding structure of the cantilever position, compared with the existing modulus fixed disc buckle frame, the adjustment of the rod position is more flexible, which can avoid the damage of the rod caused by stress concentration and the problem of slurry leakage caused by formwork loosening.
