Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a steel structure support direction, and in particular to a building support structure. Background Art

[0002] Functional support frames on building roofs are an indispensable part of modern buildings, especially when additional equipment or facilities (such as water storage tanks, solar panels, communication equipment, etc.) need to be installed. These support frames not only need to bear the weight of the equipment itself, but also need to consider the impact of environmental factors such as wind pressure and snow load on the roof structure.

[0003] At present, the functional support frame of the building roof is generally made of standard steel profiles spliced ​​into a rectangular frame. Since the rectangular frame structure has a large demand for steel profiles, especially in the case of large spans or high load requirements, the material cost increases significantly. In addition to the material cost, the processing, transportation and installation costs are also relatively high. Especially in high-rise or complex structure buildings, the installation difficulty and cost will further increase.

[0004] For this purpose, a building support structure is proposed. Utility Model Content

[0005] In view of this, the utility model hopes to provide a building support structure to solve or alleviate the technical problems existing in the prior art, that is, how to use less materials to reduce production and construction costs while meeting the premise of better pressure resistance, and at least provide a beneficial option for this; the technical solution of the utility model is implemented as follows:

[0006] The invention comprises a frame assembly 1 which is in a frame shape and is used for bearing and bearing pressure, and the frame assembly 1 comprises:

[0007] (1) Triangle a located in the middle and responsible for bearing pressure,

[0008] (2) an isosceles triangle b symmetrically located on both sides of the triangle a and dispersing the pressure to its two isosceles sides when an external force acts on the top edge of the frame, wherein a straight side of the isosceles triangle b constitutes the top edge of the frame;

[0009] At the same time, in the side view of the frame assembly 1, the other straight side of the isosceles triangle b is bifurcated to disperse and bear pressure in multiple directions and angles, and is not parallel to the plane of the front view, and the "other straight side" forms a triangle e with its hypotenuse; when external force acts on the trapezoidal support frame assembly, the bifurcated layout helps to optimize the force transmission path; it can disperse the external force to more structural elements, including the outer sides of triangle e and other adjacent triangles or structural parts, thereby reducing the concentration of local stress.

[0010] In one embodiment, the frame assembly 1 includes a plurality of outer rods 102, each side of the triangle a, the isosceles triangle b, and the triangle e is a different outer rod 102, and the triangle a, the isosceles triangle b, and the triangle e are formed by connecting different outer rods 102. Thus, under the same volume, less material can be used to achieve a compression resistance effect similar to that of traditional profiles.

[0011] In one embodiment, the frame assembly 1 includes a plurality of connecting ball assemblies 101 for connecting the outer rod bodies 102 to each other.

[0012] The connecting ball assembly 101 includes a sphere 101 and an inner rod 103 fixed to the sphere 1011, the inner rod 103 can be slidably matched with the inner wall of the outer rod 102, and the inner rod 103 and the outer rod 102 are fixedly connected by bolts. Furthermore, by adjusting the sliding amount of the inner rod 103 and the outer rod 102, the size of the above-mentioned multiple triangles can be controlled, and then the volume of the frame assembly 1 can be controlled, and it is fixed by instant drilling and bolting.

[0013] In one embodiment, the inner cavity 1013 of the ball body 1011 of the connecting ball assembly 101 is a vacuum. When in use, the air valve 1014 connected to the connecting ball assembly 101 evacuates its cavity structure to a vacuum, so that the inner wall is no longer affected by air pressure. In the vacuum state, the stress generated by the connection of the inner rod body 103 and its own structural stress are mainly borne. In the vacuum state, the stress caused by the internal and external pressure difference is reduced, so that the connecting ball assembly 101 is more evenly stressed.

[0014] In one embodiment, an adjustable base assembly 2 for bottom support is provided at the bottom of the frame assembly 1, and the adjustable base assembly 2 is used to adjust the length of the base sides of the triangle a and the isosceles triangle b, that is, the ground contact area of ​​the frame assembly 1.

[0015] Among them, the adjustable base assembly 2 includes a base 201 fixed to the ground, the base 201 is provided with a lower narrow slide groove 2012 and an upper wide slide groove 2011 with a tooth structure, a slider 2013 is slidably matched with the lower narrow slide groove 2012, and the upper surface of the slider 2013 is threadedly connected with a fastener 2014, the fastener 2014 is composed of a bolt and a clamping block f sleeved on the bolt, and the clamping block f can be clamped in the tooth structure of the upper wide slide groove 2011.

[0016] When in use, after determining the ground contact area of ​​the frame assembly 1, slide the slider 2013 to the corresponding position, and then fix the bolt in the corresponding sphere 1011 of the connecting ball assembly 101, and screw the block f into the tooth structure of the upper wide slide groove 2011 by rotating the bolt, thereby achieving adjustable fixation.

[0017] In one embodiment, a storage platform 3 for placing objects is fixedly connected to the frame assembly 1. That is, the corresponding connection ball assembly 101 located at the upper part is threadedly connected to the storage platform 3 through a knob 1012. The main body of the knob 1012 is a screw structure, which is connected to the ball 1011 of the connection ball assembly 101 through threaded matching.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. Flexibility and adjustability: The frame assembly 1 of the utility model adopts a design of multiple outer rods 102 and connecting ball assemblies 101, which makes the structure extremely flexible and adjustable. Users can easily control the size of triangle a, isosceles triangle b and triangle e by adjusting the sliding amount of inner rod 103 and outer rod 102 according to actual needs, and then adjust the volume and shape of the entire frame assembly 1.

[0020] 2. Cost-effectiveness: Since the utility model is highly adjustable and flexible, the same set of frame components 1 can be adapted to different usage scenarios through simple adjustments, thereby reducing manufacturing costs and storage costs. Since the same compressive resistance can be achieved with less material, the most direct benefit is the saving in material costs. This can significantly reduce the cost of purchasing raw materials for companies that mass-produce and use profiles. Using less material also means that energy consumption, labor and time costs in the processing process will be reduced accordingly. For example, the workload of processes such as cutting, welding, and grinding will be reduced, thereby improving production efficiency. At the same time, less material use also means that less waste will be generated during the production process, which is of great significance for reducing the environmental burden and promoting sustainable development.

[0021] 3. Stability and load-bearing capacity: The inner cavity 1013 of the ball 1011 in the connection ball assembly 101 of the utility model is designed to be in a vacuum state, which reduces the stress caused by the internal and external pressure difference, makes the connection ball assembly 101 more evenly stressed, and improves the stability and load-bearing capacity of the structure. At the same time, this design also helps to extend the service life of the connection ball assembly 101.

[0022] 4. Diversified application scenarios: The design of the adjustable base assembly 2 of the utility model enables the frame assembly 1 to adapt to different use environments and load requirements. By adjusting the position of the slider 2013, the ground contact area of ​​the frame assembly 1 can be easily changed, increasing its applicability and flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned purposes, features and advantages of the utility model more understandable, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited to the specific embodiments disclosed below;

[0035] Example 1: In the prior art, the functional support frame of the building roof is generally made of standard steel profiles spliced ​​into a rectangular frame. Since the rectangular frame structure has a large demand for steel profiles, especially in the case of large spans or high load requirements, the material cost increases significantly; for this reason, please refer to Figure 1-7 , this embodiment will provide a technical solution of the building support structure to solve the above technical problems:

[0036] In this example, see Figures 1 to 4 : It includes a frame assembly 1 in a frame shape and used for bearing and bearing pressure. The design of the frame assembly 1 adopts a structure projected into a specific geometric shape in a front view, including a triangle a located in the middle, and isosceles triangles b symmetrically located on both sides of triangle a. The straight sides of the isosceles triangle b constitute the top side of the frame, so that when an external force acts on the top side of the frame, the pressure can be effectively dispersed to the two isosceles sides of the isosceles triangle b.

[0037] Among them, when an external force acts on the top edge of an isosceles triangle, the force will be transmitted downward along the two sides of the triangle (i.e., the isosceles sides). Since the lengths of the isosceles sides are equal, the force is evenly distributed on these two sides. This force dispersion reduces the risk of single-point force and makes the entire structure more stable. That is, when an external force acts on the top edge, the force can be smoothly transmitted along the isosceles sides to other parts of the frame. The continuity of the material helps to further disperse and reduce the impact of single-point force.

[0038] At the same time, in the side view of the frame assembly 1, the other straight side of the isosceles triangle b adopts a bifurcated design, which makes the straight side not parallel to the plane of the front view, and together with the hypotenuse of the isosceles triangle b, forms a triangle e. Such a layout helps to disperse the external force to more structural elements, including the outer side of triangle e and other adjacent triangles or structural parts, when the external force acts on the trapezoidal support frame assembly, thereby achieving optimized force transmission and reducing the concentration of local stress.

[0039] Among them, when external force acts on the trapezoidal support frame assembly, the force can be dispersed to more structural elements through these different paths, thereby reducing the risk of single-point force. The bifurcated design helps to achieve force dispersion and balance inside the frame assembly 1. When external force acts on the frame, the force can be dispersed to adjacent structural elements through triangle e, thereby achieving force balance. The force dispersion and balancing effect helps to reduce local stress concentration in the frame assembly 1 and improve its overall bearing capacity.

[0040] Specifically: The design principle of the frame component 1 is based on geometric stability and dispersed force transmission. As the core part of the structure, the stability of triangle a provides a solid foundation for the overall structure, which can effectively resist external forces and maintain the overall stability of the structure. The design of the isosceles triangle b utilizes its geometric characteristics to disperse the pressure on the top edge to the two isosceles sides, thereby reducing local pressure concentration. In the side view, the other straight side of the isosceles triangle b adopts a bifurcated design, which further enhances the stability of the structure because it can disperse and withstand pressure in multiple directions and angles. When external force acts on the structure, the bifurcated layout can optimize the force transmission path and disperse the external force to more structural elements, thereby improving the overall compressive performance.

[0041] It can be understood that in the above scheme: the functionality of the frame assembly 1 is mainly reflected in its strong compressive resistance and optimized force transmission. The combined design of triangle a and isosceles triangle b enables the structure to remain stable when subjected to external forces and effectively resist pressure. The bifurcated design of isosceles triangle b further enhances the stability of the structure because it can disperse the external force to more structural elements, including the outer side of triangle e and other adjacent triangles or structural parts. Such a design not only reduces the concentration of local stress, but also improves the overall compressive resistance.

[0042] In this example, see Figure 2-3 : In a specific embodiment of the frame assembly 1, multiple outer rods 102 are used as the basic unit of the structure. These outer rods 102 are cleverly combined together to form each side of triangle a, isosceles triangle b and triangle e. Specifically, triangle a, isosceles triangle b and triangle e are not cut or bent from a whole piece of material, but are formed by connecting different outer rods 102 through connectors or welding. This design method allows the outer rods 102 of appropriate length and specifications to be selected and combined according to actual needs when constructing the frame assembly 1, thereby maximizing the utilization of materials.

[0043] Specifically: The principle of this embodiment is to make full use of the strength and stability of the outer rod 102, and form a frame assembly 1 with excellent compressive resistance through reasonable combination and connection. Since each triangle is connected by different outer rods 102, under the action of external force, these outer rods 102 can bear the pressure together and disperse the pressure to the entire structure through the connection points. This way of dispersing pressure effectively improves the overall stability of the structure, so that the frame assembly 1 can use less material to achieve a compressive resistance effect similar to that of traditional profiles under the same volume.

[0044] It can be understood that in the above scheme: the frame assembly 1 formed by connecting multiple outer rods 102 has significant advantages. First, it maximizes the utilization of materials and reduces manufacturing costs. Secondly, due to the design method of dispersing pressure, the frame assembly 1 can better maintain stability when subjected to external forces, thereby improving the overall pressure resistance. In addition, the frame assembly 1 is more flexible and convenient in assembly and disassembly, and can be quickly assembled or adjusted according to actual needs.

[0045] In this example, see Figure 5 : In a specific embodiment of the frame assembly 1, a connecting ball assembly 101 is introduced as a connecting element between the outer rod body 102. The connecting ball assembly 101 is composed of a sphere 101 and an inner rod body 103 fixed in the sphere 101. The design of the inner rod body 103 enables it to slide and fit on the inner wall of the outer rod body 102, and such a sliding fit relationship provides adjustability for the frame assembly 1. In practical applications, the inner rod body 103 and the outer rod body 102 are fixedly connected by bolts to ensure the stability and reliability of the structure. By adjusting the sliding amount between the inner rod body 103 and the outer rod body 102, the size of triangle a, isosceles triangle b and triangle e can be flexibly controlled, thereby achieving precise control of the overall volume of the frame assembly 1. After the adjustment is completed, it is fixed by immediate drilling and bolting to ensure the stability and safety of the structure.

[0046] Specifically: The principle of this embodiment is to utilize the sliding fit relationship between the inner rod body 103 and the outer rod body 102 in the connecting ball assembly 101 to achieve the adjustability of the frame assembly 1. The ball body 101 serves as a connection point, allowing the outer rod body 102 to be connected and angle-adjusted in different directions. The design of the inner rod body 103 enables it to slide inside the outer rod body 102, thereby changing the effective connection length between the outer rod bodies 102. Through the fixing action of the bolts, the inner rod body 103 and the outer rod body 102 can be firmly connected together to ensure the stability and load-bearing capacity of the structure. This design principle enables the frame assembly 1 to be flexibly adjusted and optimized according to actual needs to adapt to different application scenarios and load-bearing requirements.

[0047] It should be pointed out that if Figures 1 to 5 The inner rod body 103 and the outer rod body 102 are bolted together through temporary (ie, real) openings. In the figure, for ease of display, the inner rod body 103 and the outer rod body 102 have reached the maximum travel point, that is, the inner rod body 103 is fully wrapped by the outer rod body 102.

[0048] It can be understood that in the above scheme: the frame assembly 1 using the connecting ball assembly 101 realizes the adjustability of the frame assembly 1, so that the user can flexibly adjust the size and shape of the structure according to actual needs. This adjustability not only improves the applicability of the frame assembly 1, but also reduces the manufacturing cost and storage cost. Secondly, through the fixing effect of the bolts, the stability and safety of the structure are guaranteed, so that the frame assembly 1 can withstand large external forces and remain stable. In addition, this design method also simplifies the assembly and disassembly process of the frame assembly 1, and improves the construction efficiency and convenience of use.

[0049] In this example, see Figure 2 , 3 5: The bottom of the frame assembly 1 is designed with an adjustable base assembly 2 for supporting the entire frame and adjusting its ground contact area. The adjustable base assembly 2 is mainly composed of a base 201 fixed to the ground, and a lower narrow groove 2012 and an upper wide groove 2011 are provided on the base 201, wherein the lower narrow groove 2012 is used for the sliding fit of the slider 2013, and the upper wide groove 2011 has a tooth structure for engaging with the block f of the fastener 2014. The upper surface of the slider 2013 is threadedly connected with the fastener 2014, and the fastener 2014 is composed of a bolt and a block f. When in use, first determine the ground contact area of ​​the frame assembly 1 according to the requirements, and then slide the slider 2013 to the corresponding position. Then, fix the bolt in the ball 1011 of the corresponding connecting ball assembly 101, and screw the block f into the tooth structure of the upper wide groove 2011 by rotating the bolt, so as to achieve adjustable fixation.

[0050] Specifically, the principle of the above embodiment is to utilize the sliding property of the slider 2013 in the lower narrow slot 2012 and the clamping effect of the fastener 2014 and the tooth structure of the upper wide slot 2011 to achieve the adjustable ground contact area of ​​the frame assembly 1. When the slider 2013 slides in the lower narrow slot 2012, it will drive the part of the frame assembly 1 connected thereto to move, thereby changing the ground contact area. The fixed connection between the bolt of the fastener 2014 and the ball 1011, and the clamping effect of the clamping block f and the tooth structure of the upper wide slot 2011, ensure the stability and fixity of the frame assembly 1 after adjustment.

[0051] It can be understood that in the above scheme: the design of the adjustable base assembly 2 provides great flexibility and applicability for the frame assembly 1. By adjusting the position of the slider 2013, the ground contact area of ​​the frame assembly 1 can be easily changed to adapt to different use environments and load requirements. At the same time, the clamping action of the fastener 2014 and the tooth structure of the upper wide slide 2011 ensures the stability and safety of the frame assembly 1 after adjustment. This design method not only improves the applicability of the frame assembly 1, but also reduces the manufacturing cost and storage cost, because the same set of frame assembly 1 can be adapted to different use scenarios through simple adjustment.

[0052] In this example, see Figures 1 to 4 : In order to increase its practicality and functionality, a storage table 3 for placing items is specially designed. This storage table 3 is connected to the upper part of the frame assembly 1 in a fixed manner, specifically, it is connected to the storage table 3 through the corresponding connecting ball assembly 101 located at the upper part. In order to achieve this connection, the connecting ball assembly 101 is equipped with a knob 1012, and the main body of the knob 1012 is a screw structure, which is connected to the ball 1011 of the connecting ball assembly 101 by threaded matching. In this way, the storage table 3 can be firmly fixed to the frame assembly 1 through the knob 1012, providing a stable storage space for users.

[0053] Specifically, the screw structure of the knob 1012 and the ball 1011 of the connecting ball assembly 101 are used to achieve a firm connection between the storage platform 3 and the frame assembly 1. When the knob 1012 is tightened, its screw structure will penetrate into the ball 1011, and the storage platform 3 will be firmly fixed on the frame assembly 1 through the bite of the screw thread. This connection method is not only simple and convenient, but also has high stability and load-bearing capacity, which can ensure the safety and reliability of the storage platform 3 during use.

[0054] It should be noted that when the top sides of the triangle a and the isosceles triangle b are adjusted, the form of the preset openings on the storage table 3 will cause interference with the mechanism, especially the interference with the connecting ball assembly 101 in the area d in the figure. Therefore, it is recommended that in practice, according to the actual positions of the triangle a and the isosceles triangle b, the connecting holes are opened in real time and matched with the connecting ball assembly 101 in the area d.

[0055] It is understandable that in the above scheme: the design of fixing the storage table 3 on the frame assembly 1 provides the user with additional storage space, so that the frame assembly 1 is not only a supporting structure, but also a practical storage platform. Secondly, the threaded connection between the knob 1012 and the connecting ball assembly 101 ensures the firm connection and stability between the storage table 3 and the frame assembly 1, so that the user can safely place items on the storage table 3. In addition, this design method also makes the disassembly and installation of the storage table 3 very simple and convenient, and the user can adjust or replace the storage table 3 at any time according to actual needs.

[0056] Embodiment 2: Based on Embodiment 1, this embodiment further optimizes the structure provided in Embodiment 1:

[0057] In this example, see Figures 6-7 The ball 1011 of the connecting ball assembly 101 is specially designed to have an inner cavity 1013, and this inner cavity 1013 is evacuated to a vacuum state when in use. In order to realize this design, the ball 1011 is equipped with an air valve 1014 connected to the inner cavity 1013. When in use, the inner cavity 1013 of the ball 1011 is evacuated to a vacuum through the air valve 1014 connected to an external air extraction device, so that the inner wall of the ball 1011 is no longer affected by air pressure. In this vacuum state, the connecting ball assembly 101 is mainly subjected to the stress generated by the inner rod body 103 through the connection and its own structural stress.

[0058] Specifically: The principle of the above embodiment is to use the vacuum state to reduce the stress caused by the internal and external pressure difference. When the inner cavity 1013 of the sphere 1011 is evacuated to a vacuum, the inner wall of the sphere 1011 is no longer affected by the air pressure, so the stress caused by the internal and external pressure difference is greatly reduced. In this way, the connecting ball assembly 101 is more uniform when subjected to force, and can effectively resist external pressure and maintain structural stability. At the same time, since the stress caused by the internal and external pressure difference is reduced, the service life and bearing capacity of the connecting ball assembly 101 are also improved.

[0059] It can be understood that in the above scheme: the implementation method in which the inner cavity 1013 of the ball body 1011 of the connecting ball assembly 101 is designed to be in a vacuum state has significant advantages. First, the stress caused by the internal and external pressure difference is reduced, so that the connecting ball assembly 101 is more uniform when subjected to force, and the stability and bearing capacity of the structure are improved. Secondly, the design of the vacuum state also helps to improve the service life and durability of the connecting ball assembly 101, because it reduces fatigue and damage caused by air pressure. In addition, this design method also makes the connecting ball assembly 101 more suitable for special environments such as high altitudes and low air pressure, because the air pressure in these environments is low and the impact on the connecting ball assembly 101 is also small. Therefore, the connecting ball assembly 101 of this embodiment has broad application prospects in the fields of construction, machinery, aerospace, etc.

[0060] It should be pointed out that the inner cavity 1013 of the sphere 1011 needs to be equipped with a sealing ring 1015 and other structures to seal the matching parts of other structural parts.

[0061] It should be noted that in the first embodiment Figure 5 In the embodiment, the sphere 1011 is a solid structure, but in this embodiment, reference should be made to Figure 7 The sphere 1011 structure shown in the figure; meanwhile, in practice, the specific type can also be selected according to the scheme of this embodiment or the scheme of embodiment 1. Figure 5 or Figure 7 The sphere 1011 structure.

[0062] Test example 1:

[0063] 1. Overview:

[0064] This case aims to verify the advantages of a new type of building support structure in terms of material efficiency and compressive performance by comparing it with a frame structure built using traditional technology. Carbon steel (following the GB / T699-1999 standard) was used as a unified material to ensure a fair comparison. Through precise modeling and finite element simulation, the performance of the two structures under the same load conditions was evaluated.

[0065] (II) Experimental Materials and Methods

[0066] 2.1 Experimental group structure:

[0067] As in the structures disclosed in Examples 1 and 2, the main material is carbon steel (GB / T699-1999) with a density of 7.85t / m3. The structural dimensions are 2.2m long, 1.7m wide and 1.5m high;

[0068] 2.2 Control group structure:

[0069] The traditional frame structure is also made of carbon steel (GB / T699-1999) with a density of 7.85t / m3. Its dimensions are consistent with those of the experimental group, i.e., 2.2m long, 1.7m wide, and 1.5m high, and is welded from 40b I-beams.

[0070] (III) Test methods:

[0071] Autodesk Inventor software was used to build three-dimensional models of the experimental group and the control group. In the software assembly environment, the finite element simulation module of Autodesk Inventor was used for simulation analysis.

[0072] Conventional gravity conditions were imposed on both structures and a homogeneous water tower was placed on top of them with a weight of 1.8 tons to simulate the actual load.

[0073] The modal analysis mode was used to perform finite element simulation and output a visual image of the structural deformation. The material volume calculation function of the software was used to accurately measure and record the total amount of material used in the two structures.

[0074] (IV) Experimental results and analysis:

[0075] 4.1 Structural deformation:

[0076] like Figures 8-9 As shown, the outer rods in the experimental group showed only slight deformation, while the supported water tower remained stably fixed to the structure, indicating good load-bearing capacity and structural stability. In contrast, the top area of ​​the control group showed moderate deformation, indicating that its compressive resistance was relatively weak.

[0077] 4.2 Material utilization efficiency:

[0078] like Figures 8-9 As shown, under the same total volume limit, the control group consumed 140.784 kg of carbon steel materials, and the experimental group structure only used 80.283 kg of carbon steel materials, which is roughly half of the control group. This shows that the new structure provided by this specific embodiment is more efficient in material use, achieving a lightweight design while maintaining excellent mechanical properties.

[0079] (V) Conclusion:

[0080] This case study shows through comparative analysis that the new building support structure has significant advantages over the traditional frame structure in terms of materials and compressive performance. It can not only effectively resist external loads and maintain structural stability, but also save more materials, reflecting higher design efficiency and sustainability.

[0081] The above-mentioned embodiments only express the implementation methods of the relevant practical applications of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
