Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a three-dimensional cross-shaped node positioning structure and its installation method. Background Technology

[0002] Steel components refer to composite steel structural members capable of bearing and transmitting loads, constructed from steel plates, angle steel, channel steel, I-beams, welded steel, or hot-rolled H-beams that have been cold-bent or welded and connected by connectors. During construction, the nodes of the cross-shaped steel components need to be erected on supporting frames for installation and positioning. If there is a deviation in the initial on-site positioning, the resources required for secondary positioning are essentially the same as for the initial positioning, resulting in significant on-site correction costs. Therefore, after the initial positioning of the steel components is accurate, their positions need to be firmly fixed to prevent loosening and displacement due to external forces.

[0003] Currently, the method simply uses a support frame to elevate the star-shaped steel components, but there is no effective measure to secure them after positioning. However, during construction, disturbance to the star-shaped steel components is inevitable due to the operation of large machinery or workers, resulting in low work efficiency and increased costs due to secondary positioning. Summary of the Invention

[0004] To improve construction efficiency and reduce positioning costs, this application provides a three-dimensional cross-shaped node positioning structure and installation method.

[0005] On the one hand, the three-dimensional cross-shaped node positioning structure provided in this application adopts the following technical solution:

[0006] A three-dimensional cross-shaped node positioning structure includes:

[0007] The support frame is installed at the required positioning location of the star-shaped steel component;

[0008] A platform fixing clip is embedded in the support frame, and the upper surface of the platform fixing clip and the upper surface of the support frame are on the same plane;

[0009] A fixing component is provided on the platform fixing clip. The fixing component includes a fixing buckle embedded in the platform fixing clip and a fixing screw disposed inside the fixing buckle. There is space between the fixing buckle and the fixing screw for embedding the cross-shaped steel component.

[0010] By adopting the above technical solution, during the construction process, preparatory work is first carried out to reduce the positioning space to the position of the support frame. Then, the position of the support frame is fixed, and positioning is performed on the support frame. The platform positioning clip installation rod is installed on the support frame, thereby reducing the required positioning range. Then, the cross-shaped steel component is fixed by adjusting the fixing buckles and fixing screws in the fixing components. Finally, by positioning the fixing components, the fixing screws and fixing buckles are installed on the platform fixing clips, thereby indirectly positioning the cross-shaped steel component.

[0011] Optionally, multiple fixing screws are provided, which are spaced apart and form a regular quadrilateral.

[0012] By adopting the above technical solution, multiple fixing screws are provided, thus giving them a stable supporting force. Adjusting a single fixing screw at a different position allows for fine-tuning of the star-shaped steel component, resulting in more precise positioning. Furthermore, adjustments can be made according to the required location during the adjustment process.

[0013] Optionally, the fixing screws are arranged in pairs, and the center of the regular quadrilateral formed by multiple fixing screws is also provided with a fixing screw, with the central fixing screw located at the center of the connecting line between two opposing fixing screws.

[0014] By adopting the above technical solution, two fixing screws are used, and these two screws are symmetrically arranged, thus ensuring a uniform distribution of the force applied to the star-shaped steel component. This avoids uneven stress on the star-shaped steel component, which could prevent it from being placed parallel to the ground. Furthermore, the screws also provide support in the middle, ensuring the stability of the star-shaped steel component.

[0015] Optionally, a steel pad is provided on the support frame, the steel pad is connected to the platform fixing clip, and the fixing screw can be inserted into the steel pad at the same time.

[0016] By adopting the above technical solution, the steel pad can insert a positioning transition between the platform fixing clips and the fixing components, while adding an extra positioning step, making the positioning more accurate. During operation, after the platform fixing clips are installed, the steel pad can be used to further reduce the area, thereby making the positioning even more precise.

[0017] Optionally, the support frame has a hollowed-out center, the fixing component is along the edge of the support frame, and the fixing buckle is perpendicular to the edge of the support frame.

[0018] By adopting the above technical solution, the support frame is hollowed out in the middle, which reduces the amount of raw materials and weight while still providing support, thereby reducing manpower. Furthermore, the fixing components can be arranged around the circumference of the support frame, which can simultaneously fix the positions of multiple cross-shaped steel components, thereby further improving the positioning efficiency of multiple components.

[0019] On the other hand, the three-dimensional cross-shaped node positioning structure provided in this application adopts the following technical solution:

[0020] Optional steps include:

[0021] Preparation: Conduct comprehensive measurements, place the support frame at the required positioning location on the cross-shaped steel component, and fix the position of the support frame;

[0022] Installation and repositioning: Fix the platform fixing clips and steel pads to the support frame, and further position the cross-shaped steel components on the steel pads.

[0023] Install the fixing components: After repositioning, install the fixing screws and fixing clips into the corresponding positions on the steel pads, leaving space between the fixing screws and fixing clips for the placement of the cross-shaped steel components;

[0024] Adjusting the fixing components: After placing the star-shaped steel component in the space, tighten the fixing screws to press the star-shaped steel component tightly from the bottom, and adjust the fixing buckles to press the star-shaped steel component tightly from the top.

[0025] Secure the steel component by locking the fixing screws and clips onto the steel pad.

[0026] By adopting the above technical solution, preparatory work needs to be carried out first during the construction process. The position of the most basic support frame is fixed first, and then the positioning is carried out on the support frame to reduce the required positioning range. Then, the cross-shaped steel component is fixed by adjusting the fixing components, and then the cross-shaped steel component is indirectly positioned by positioning the fixing components.

[0027] Optionally, comprehensive measurements can be performed, including the following steps: by determining the dimensional relationships between the working points of each node in the on-site construction and the center points of each component, the design coordinate values ​​of the cross-shaped steel component can be obtained, and a three-dimensional spatial model of the node can be established.

[0028] By adopting the above technical solution, comprehensive testing is required during positioning to ensure accuracy. Positioning involves measuring the working points of each node and the dimensions of each component at the construction site to determine the location of the center point. A three-dimensional spatial model is then established based on these coordinates. The more points determined, the more accurate the modeling, thus ensuring the positioning of the cross-shaped steel structure.

[0029] Optionally, the positioning position of the cross-shaped steel component can be further positioned on the steel pad, including the following steps: using a measuring instrument to detect the external dimensions of the steel pad, measuring the coordinates on the steel pad, and automatically converting the obtained relative coordinate values ​​into geometric figures, i.e., solid models, through drawing software, and then positioning them according to the actual situation using the solid model.

[0030] By adopting the above technical solution, the position of the star-shaped steel component needs to be further located within the range of the steel base plate. During positioning, a measuring instrument is required to measure the shape and dimensions of the steel base plate, which facilitates subsequent modeling. Through analysis, the specific positioning of the star-shaped steel component can be obtained, making the positioning more accurate.

[0031] Optionally, the fixing screws and fixing clips are installed on the corresponding positions of the steel pad, including the following steps: make the geometric center point and measurement point on the connecting main end face of the steel pad, then perform physical measurement and make measurement records, input each point according to the measurement records and mark it, then make the corresponding simulated plane according to the input points, and install the fixing screws and fixing clips according to the positions on the plane.

[0032] By adopting the above technical solution, in order to make the positioning of the star-shaped steel components more accurate, the fixing screws and fixing clips are positioned to achieve indirect positioning of the star-shaped steel components. In the positioning of the fixing screws and fixing clips, it is necessary to measure the main end face of the steel pad connection, mark the center point, simulate the model, analyze the position that needs to be positioned, and perform positioning in reality to achieve the positioning of the fixing screws and fixing clips.

[0033] Optionally, the fixing screws and fixing clips are locked in the position of the steel pad, including the following steps: During installation, the fixing screws and fixing clips are first arranged on the steel pad. After the cross-shaped steel components are placed, the fixing screws and fixing clips are then embedded in the steel pad, and the positions of the fixing screws and fixing clips are fixed with expansion screws.

[0034] By adopting the above technical solution, during installation, since the position of the star-shaped steel component cannot be accurately determined beforehand, it is necessary to pre-install the fixing screws and fixing clips. The star-shaped steel component is placed between the fixing screws and fixing clips. The position of the star-shaped steel component is first fixed by adjusting the distance between the fixing screws and fixing clips. Then, the position of the fixing screws and fixing clips is positioned and fixed, thereby realizing the positioning of the star-shaped steel structure.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] By setting up a support frame, platform fixing clips, fixing components, fixing buckles, and fixing screws, the construction process involves first preparing by narrowing down the positioning space to the position of the support frame, then fixing the position of the support frame, and then positioning the platform positioning clips on the support frame to reduce the required positioning range. The cross-shaped steel component is then fixed by adjusting the fixing buckles and fixing screws in the fixing components. Finally, the fixing components are positioned, and the fixing screws and fixing buckles are installed on the platform fixing clips to indirectly position the cross-shaped steel component.

[0037] By incorporating a steel pad, a positioning transition is inserted between the platform fixing clips and the fixing components, adding an extra layer of positioning for greater accuracy. During operation, after installing the platform fixing clips, the steel pad can be used to further reduce the area, thereby achieving even greater positioning precision. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0044] On the one hand, this application discloses a three-dimensional cross-shaped node positioning structure.

[0045] Reference Figure 1 and Figure 2 A three-dimensional cross-shaped node positioning structure includes a support frame 1 set at the required positioning position of the cross-shaped steel component, a platform fixing clip 2 embedded in the support frame 1, and a fixing component 3 set on the platform fixing clip 2.

[0046] The upper surface of the platform fixing clip 2 and the upper surface of the support frame 1 are on the same plane; the fixing component 3 includes a fixing buckle 31 embedded in the platform fixing clip 2 and a fixing screw 32 disposed inside the fixing buckle 31, and there is space between the fixing buckle 31 and the fixing screw 32 for embedding the cross-shaped steel component.

[0047] During construction, preparatory work is first carried out to reduce the positioning space to the position of support frame 1. Then, the position of support frame 1 is fixed, and positioning is performed on support frame 1. The platform positioning clip installation rod is installed on support frame 1, thereby reducing the required positioning range. Then, the cross-shaped steel component is fixed by adjusting the fixing buckle 31 and fixing screw 32 in the fixing component 3. Then, by positioning the fixing component 3, the fixing screw 32 and fixing buckle 31 are respectively installed on the flat platform fixing clip 2, thereby indirectly positioning the cross-shaped steel component.

[0048] Reference Figure 1 and Figure 2 Multiple fixing screws 32 are provided, arranged in pairs, with the multiple fixing screws 32 spaced apart, forming a regular quadrilateral. A fixing screw 32 is also positioned at the center of the quadrilateral, with the central fixing screw 32 located at the center of the line connecting two opposite fixing screws 32. This application uses a quadrilateral with four fixing screws 32 as an example. The four fixing screws 32 are symmetrical in pairs, and the line connecting them lies on the same straight line as the diagonal of the quadrilateral.

[0049] Multiple fixing screws 32 are provided, thus providing a stable supporting force. Fine-tuning of the star-shaped steel component can be achieved by adjusting one fixing screw 32 at different positions, resulting in more precise positioning. Furthermore, adjustments can be made according to the required position. Two symmetrical fixing screws 32 ensure a uniform distribution of force applied to the star-shaped steel component, preventing uneven stress that could cause it to not be placed parallel to the ground. Additionally, the screws provide support in the middle, ensuring the stability of the star-shaped steel component.

[0050] Reference Figure 1 and Figure 2A steel pad 4 is installed on the support frame 1. The steel pad 4 is connected to the platform fixing clip 2, and the fixing screw 32 can be inserted into the steel pad 4. The steel pad 4 can insert a positioning transition between the platform fixing clip 2 and the fixing component 3, and at the same time add a positioning step, making the positioning more accurate. During operation, after the platform fixing clip 2 is installed, the area can be further reduced by setting the steel pad 4, thereby making the positioning even more accurate.

[0051] The support frame 1 has a hollow center, and the fixing component 3 is arranged along the edge of the support frame 1. The fixing buckle 31 is perpendicular to the edge of the support frame 1. The hollow center of the support frame 1 reduces the amount of raw materials and weight while still providing support, thus reducing manpower. Furthermore, the fixing component 3 can be arranged around the circumference of the support frame 1, allowing multiple cross-shaped steel components to be fixed simultaneously, thereby further improving the positioning efficiency.

[0052] The implementation principle of a three-dimensional cross-shaped node positioning structure in this application embodiment is as follows: During the construction process, preparatory work is first carried out to reduce the positioning space to the position of the support frame 1, then the position of the support frame 1 is fixed, and then positioning is performed on the support frame 1. The platform positioning clip installation rod is installed on the support frame 1, thereby reducing the required positioning range. Then, the cross-shaped steel component is fixed by adjusting the fixing buckle 31 and fixing screw 32 in the fixing component 3. Then, by positioning the fixing component 3, the fixing screw 32 and fixing buckle 31 are respectively installed on the flat platform fixing clip 2, thereby indirectly positioning the cross-shaped steel component.

[0053] Reference Figure 3 and Figure 4 On the other hand, the three-dimensional cross-shaped node positioning structure provided in this application adopts the following technical solution:

[0054] Optional steps include:

[0055] S1. Preparation: Conduct comprehensive measurements, place support frame 1 at the required positioning position of the cross-shaped steel component, and fix the position of support frame 1.

[0056] S11. By determining the dimensional relationships between the working points of each node and the center point of each component during on-site construction, the design coordinate values ​​of the cross-shaped steel component are obtained, and a three-dimensional spatial model of the node is established.

[0057] During positioning, comprehensive testing is required to ensure accuracy. Positioning involves measuring the working points of each node and the dimensions of each component at the construction site to determine the location of the center point. A three-dimensional spatial model is then built based on these coordinates. The more points identified, the more accurate the modeling, thus ensuring the precise positioning of the cross-shaped steel structure.

[0058] S2. Installation and repositioning: Fix the platform fixing clip 2 and steel pad 4 to the support frame 1, and further position the cross-shaped steel component on the steel pad 4;

[0059] S21. Use a measuring instrument to inspect the external dimensions of the steel pad 4, perform coordinate measurements on the steel pad 4, and automatically convert the obtained relative coordinate values ​​into geometric figures, i.e., solid models, using drawing software. Then, use the solid models to locate and correspond to the actual situation.

[0060] The position of the star-shaped steel component needs to be further determined within the range of the steel base plate 4. During positioning, a measuring instrument is required to measure the shape and dimensions of the steel base plate 4 to facilitate subsequent modeling. Through analysis, the specific positioning of the star-shaped steel component can be obtained, making the positioning more accurate.

[0061] S3. Install the fixing component 3: After repositioning, install the fixing screw 32 and the fixing buckle 31 to the corresponding positions of the steel pad 4 respectively, leaving space between the fixing screw 32 and the fixing buckle 31 for the placement of the cross-shaped steel component;

[0062] S31. Make the geometric center point and measurement point on the connecting main end face of the steel pad 4, then perform physical measurement and make measurement records. Input each point according to the measurement records and mark it. Then make the corresponding simulated plane according to the input points. Install the fixing screw 32 and fixing buckle 31 according to the position on the plane.

[0063] To achieve more accurate positioning of the star-shaped steel components, the fixing screws 32 and fixing clips 31 are positioned to indirectly position the star-shaped steel components. In positioning the fixing screws 32 and fixing clips 31, the connecting main end face of the steel pad 4 needs to be measured, the center point marked, a model simulated, and the required positioning position analyzed. Positioning is then performed in reality to achieve the positioning of the fixing screws 32 and fixing clips 31.

[0064] S4. Adjust the fixing component 3: After placing the cross-shaped steel component in the space, tighten the fixing screw 32 to press the cross-shaped steel component from the bottom, and adjust the fixing buckle 31 to press the cross-shaped steel component from the top.

[0065] S5. Complete the fixing: Lock the fixing screw 32 and fixing buckle 31 at the position of the steel pad 4 to complete the fixing of the steel component.

[0066] S51. During installation, first arrange the fixing screws 32 and fixing clips 31 on the steel pad 4. After the cross-shaped steel components are placed, then embed the fixing screws 32 and fixing clips 31 into the steel pad 4, and use expansion screws to fix the positions of the fixing screws 32 and fixing clips 31.

[0067] During installation, since the position of the star-shaped steel component cannot be accurately determined beforehand, the fixing screws 32 and fixing clips 31 need to be pre-installed. The star-shaped steel component is placed between the fixing screws 32 and fixing clips 31. The position of the star-shaped steel component is first fixed by adjusting the distance between the fixing screws 32 and fixing clips 31. Then, the positions of the fixing screws 32 and fixing clips 31 are positioned and fixed, thereby realizing the positioning of the star-shaped steel structure.

[0068] During construction, preparatory work is required first. The position of the most basic support frame 1 is fixed first, and then the positioning is carried out on the support frame 1 to reduce the required positioning range. Then, the cross-shaped steel component is fixed by adjusting the fixing component 3, and the cross-shaped steel component is indirectly positioned by positioning the fixing component 3.

[0069] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
