Description

Technical Field

[0001] The present invention relates to the technical field of siphonic rainwater pipe installation, and specifically to an installation method for siphonic rainwater pipes inside curtain wall columns and steel pipes columns. Background Art

[0002] Rainwater infiltration is an effective method for rainwater utilization to recharge groundwater. Its occurrence is due to the increase in national buildings, resulting in excessive hardened ground and rainwater being unable to return to the ground. Infiltration can also be combined with rainwater collection and reuse. Rainwater infiltration can be carried out in ways such as green space infiltration, permeable pavement infiltration, shallow ditch and depression infiltration, combined infiltration of shallow ditch and infiltration channel, infiltration trench, infiltration well, infiltration pond, infiltration pipe - discharge system, etc.

[0003] As the most important part of the siphonic roof rainwater drainage system, the pipeline must ensure the safe and reliable operation of the system, efficiently and continuously. As a special drainage system, the pipeline of the siphonic system must ensure complete sealing and complete fire protection measures, and also reduce noise as much as possible, absorb vibration, resist impact external forces, and meet the deformation caused by temperature changes to the greatest extent.

[0004] Siphonic rainwater pipes mainly use HDPE (high density polyethylene) pipes, which are suitable for outdoor drainage systems due to their good corrosion resistance, wear resistance and anti-aging performance.

[0005] With the continuous improvement of the quality of life, people's aesthetic concepts have also changed to a certain extent. Therefore, the requirements for the main building body have also increased. With the progress of technology, building methods such as steel structures have been introduced into airports, large factories, and stadiums. For the sake of building aesthetics, generally the entire siphonic rainwater pipe is designed inside the steel structure, especially in the steel columns during the specific operation process.

[0006] The existing invention patent with the authorized announcement number of CN115961741B and the patent name of a siphonic rainwater pipe support inside a steel structure column, a pipeline auxiliary installation support and its installation method records that it relates to the technical field of building construction. According to the support, auxiliary installation support and installation method provided by the present invention, the siphonic rainwater pipe can be firmly fixed and installed without directly contacting the steel structure column, and at the same time, the verticality of the pipeline can be effectively ensured. Furthermore, it can reduce or even effectively avoid the many inconveniences and operation safety hazards existing during the construction process of construction workers inside the steel structure column, and cannot guarantee the construction quality and progress.

[0007] The invention patent with the authorized announcement number of CN114482233B and the patent name of "A siphonic rainwater drainage system" records that it includes a mounting plate. Along the length and width directions of the mounting plate, a plurality of infiltration ports are arranged in a matrix. The output ends of the plurality of infiltration ports are externally connected with a siphon pipe. The input end of the infiltration port is externally fixed with a siphon drainage port. The output end of the siphon pipe is connected with a first water pipe. The other end of the first water pipe is fixed with a mounting shell. On one side of the mounting shell close to the mounting plate, there is an arc-shaped air collection groove. Symmetrically arranged connection grooves are provided at both ends of the mounting shell. The first water pipe extends into the connection groove. The other connection groove at the other end of the mounting shell is connected with a second water pipe. A through hole is provided in the mounting shell. A single-floating sliding pipe is slidably arranged in the through hole. The single-floating sliding pipe is elastically connected with the side wall of the through hole close to the second water pipe through a spring. The present invention can prevent the air mass inside the pipe in the siphonic rainwater drainage system from affecting the drainage efficiency and at the same time increase the drainage channel inside the water pipe to make the drainage efficiency higher.

[0008] The central idea of the above patent is to set a sliding track and use the sliding track to slide the inner siphon rainwater pipe located in the steel structure column, which is convenient for the docking of the entire inner siphon rainwater pipe, mainly to facilitate the connection of the pipes.

[0009] However, the above solution is only applicable to the local steel structure column, and its application scenario is limited. The traditional method is to install and fix the siphon rainwater pipe outside the curtain wall column and steel pipe column. Due to the bending angle not meeting the design requirements, the siphon rainwater pipe conflicts with the beam bottom and column top beam, and at the same time, there are many bends, which cannot better meet the design requirements. Therefore, we have developed an installation method for the siphon rainwater pipe in the curtain wall column and steel pipe column. Summary of the Invention

[0010] (1) Technical problems to be solved

[0011] Aiming at the deficiencies of the prior art, the present invention provides an installation method for the siphon rainwater pipe in the curtain wall column and steel pipe column, which solves the problems that the pipeline layout is in an obvious position and affects the aesthetics, is convenient for construction, and conflicts with the pipeline installation construction specifications. It has good use effects and has a good application prospect, and solves the problems raised in the background technology.

[0012] (2) Technical solutions

[0026]

[0027] In the formula, CYz is the difference ratio, Ls is the size requirement corresponding to the number of segments of the siphonic rainwater pipes measured on site, and Ly is the size on the installation drawings of siphonic rainwater pipes;

[0028] S22. Compare the calculated difference ratio with the set standard error ratio. If the difference ratio is greater than or equal to the standard error ratio, re-collect the on-site data. If the difference ratio is less than the standard error ratio, do not make a response;

[0029] S23. Calculate the size range of the siphonic rainwater pipes based on the qualified size requirements corresponding to the number of segments of the siphonic rainwater pipes measured on site, and produce the siphonic rainwater pipes according to the size range.

[0030] Further, the calculated size range of the siphonic rainwater pipe includes the single-pipe size range and the comprehensive size range. The single-pipe size range includes the straight-pipe size range (L1 - L1×a, L1 + L1×a), the elbow size range (L2 - L2×a, L2 + L2×a), and the pipe expansion joint size range (L3 - L3×a, L3 + L3×a), where the calculation formulas for L1, L2, and L3 are as follows:

[0033] The comprehensive size range is (Lz - Lz×β, Lz + Lz×β), where 0 < β < 5%;

[0034] The calculation formula for Lz is as follows:

[0035]

[0036] In the formula, A is the number of straight pipes in the siphonic rainwater pipe, B is the number of elbows in the siphonic rainwater pipe, and C is the number of pipe expansion joints in the siphonic rainwater pipe.

[0037] Further, after planning all the sizes of the siphonic rainwater pipes, calculate the total length Lzc of the planned siphonic rainwater pipes, and then compare the total length Lzc with the comprehensive size range (Lz - Lz×β, Lz + Lz×β). If Lzc is within (Lz - Lz×β, Lz + Lz×β), no adjustment is made. If Lzc is outside (Lz - Lz×β, Lz + Lz×β), re-plan the sizes of the siphonic rainwater pipes.

[0057] Inside the curtain wall columns, use U-shaped clamps to fix the pipelines;

[0058] Connect the upper and lower ends of the pipelines inside the curtain wall columns to the horizontal pipelines to complete the installation of part of the siphonic rainwater pipelines inside the curtain wall columns.

[0075] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0076] Research and development concept: The central idea of the existing patent is to set a sliding track and use the sliding track to slide the internal siphonic rainwater pipe located in the steel structure column, which is convenient for the docking of the entire internal siphonic rainwater pipe, mainly to facilitate the connection of the pipes.

[0077] However, the above solution is only applicable to the local steel structure column, and its application scenario is limited. In addition, the existing traditional method is to install and fix the siphonic rainwater pipe outside the curtain wall column and steel pipe column. Due to the bending angle not meeting the design requirements, the siphonic rainwater pipe conflicts with the beam at the bottom and the column top beam, and there are many bends, which cannot well meet the design requirements. Therefore, we have developed an installation method for the siphonic rainwater pipe in the curtain wall column and steel pipe column recorded in the following embodiments.

[0078] Embodiment

[0079] Please refer to Figure 1 , an installation method for the siphonic rainwater pipe in the curtain wall column and steel pipe column, comprising the following steps:

[0080] S1. Obtain the measured data of the installation site of the siphonic rainwater pipe 1 and the data of the preset installation drawing of the siphonic rainwater pipe 1, and sort out the obtained data;

[0081] The steps of sorting out the obtained data are as follows:

[0082] S11. Obtain the number of segments and the pipe type of the siphonic rainwater pipe 1 in the preset installation drawing of the siphonic rainwater pipe 1;

[0083] S12. Number the number of segments of the siphonic rainwater pipe 1 and mark the type on the number;

[0084] S13. Retrieve the dimension requirements corresponding to the number of segments of the siphonic rainwater pipe 1 measured on site and the dimensions of the preset installation drawing of the siphonic rainwater pipe 1;

[0085] S14. Mark the retrieved dimension data on the number;

[0086] The preset installation drawing data of the siphonic rainwater pipe 1 are all the data marked on the design drawings in the design stage. The on-site measurement data of the siphonic rainwater pipe 1 installation in the building are the data collected through measurement at the construction site. Mainly, there are certain errors between the drawings and the actual construction. Therefore, it is necessary to combine and compare them for judgment. At the same time, there are also certain errors in the measurement. In order to ensure the accuracy of the collected data, it is necessary to further verify the collected data.

[0087] S2. Analyze the sorted data and calculate the dimensional data of the siphonic rainwater pipe 1;

[0088] S21. Calculate the difference ratio between the dimensional requirements corresponding to the number of segments of the siphonic rainwater pipe 1 measured on-site and the dimensions on the preset installation drawing of the siphonic rainwater pipe 1. The specific calculation formula is as follows:

[0089]

[0090] In the formula, CYz is the difference ratio, Ls is the dimensional requirement corresponding to the number of segments of the siphonic rainwater pipe 1 measured on-site, and Ly is the dimension on the installation drawing of the siphonic rainwater pipe 1;

[0091] S22. Compare the calculated difference ratio with the set standard error ratio. If the difference ratio is greater than or equal to the standard error ratio, re-collect the on-site data. In this case, usually the collected data is incorrect. Therefore, it is usually necessary to re-collect. If it is found through multiple collections and verifications that the collected data is correct, the design team needs to re-design the relevant scheme of the rainwater pipe to ensure that the rainwater can flow out normally. If the difference ratio is less than the standard error ratio, no response is made;

[0092] The error in normal construction is relatively small. Therefore, the difference ratio calculated based on the actual collected data will be less than the standard error ratio, indicating that the collected data is normal.

[0093] S23. Calculate the dimensional range of the siphonic rainwater pipe 1 based on the qualified dimensional requirements corresponding to the number of segments of the siphonic rainwater pipe 1 measured on-site, and produce the siphonic rainwater pipe 1 according to the dimensional range.

[0094] Calculating the dimensional range of the siphonic rainwater pipe 1 includes the single-piece dimensional range and the comprehensive dimensional range. Among them, the single-piece dimensional range includes the straight pipe dimensional range (L1 - L1×a, L1 + L1×a), the elbow dimensional range (L2 - L2×a, L2 + L2×a), and the pipe expansion joint dimensional range (L3 - L3×a, L3 + L3×a). The calculation formulas for L1, L2, and L3 are as follows:

[0095]

[0096] Wherein, Ls1 is the horizontal distance, Ls2 is the vertical drop distance, h1 - h2 is the height difference between the two ends of the pipeline, D is the diameter of the pipeline, R is the radius of the elbow, α is the expansion coefficient of the expansion joint, and 0 < a < 3%;

[0097] The single - root size range mainly limits the size of a single - section siphonic rainwater pipeline 1, avoiding the processed siphonic rainwater pipeline 1 being too long or too short, so that the subsequent installation of the pipeline is more convenient, reducing the workload of subsequent processing and having a better use effect.

[0098] The comprehensive size range is (Lz - Lz×β, Lz + Lz×β), where 0 < β < 5%;

[0099] The calculation formula of Lz is as follows:

[0100]

[0101] Wherein, A is the number of straight pipes in the siphonic rainwater pipeline 1, B is the number of elbow pipes in the siphonic rainwater pipeline 1, and C is the number of pipeline expansion joints in the siphonic rainwater pipeline 1.

[0102] After planning the size of the siphonic rainwater pipeline 1, calculate the total length Lzc of the planned siphonic rainwater pipeline 1, and then compare the total length Lzc with the comprehensive size range (Lz - Lz×β, Lz + Lz×β). If Lzc is within (Lz - Lz×β, Lz + Lz×β), no adjustment is made. If Lzc is outside (Lz - Lz×β, Lz + Lz×β), re - plan the size of the siphonic rainwater pipeline 1.

[0103] The main function of the comprehensive size range is to achieve the effect of comprehensive management, mainly to avoid the error accumulation of each section of the siphonic rainwater pipeline 1, resulting in a large error in the entire siphonic rainwater pipeline 1 formed finally and affecting the subsequent installation. Therefore, after designing the size of each section of the siphonic rainwater pipeline 1, it is also necessary to further verify the designed size. When verifying, compare Lzc with (Lz - Lz×β, Lz + Lz×β). If Lzc is inside (Lz - Lz×β, Lz + Lz×β), no treatment is required. If Lzc is outside (Lz - Lz×β, Lz + Lz×β), it means that the error is too large and the plan needs to be re - planned to reduce the error, so as to facilitate the subsequent connection of the siphonic rainwater pipeline 1, which is more convenient to use and has a good use effect.

[0104] Normally, the processed siphonic rainwater pipeline 1 is longer than the length of the siphonic rainwater pipeline 1 analyzed from the actual collected data. However, it is designed for the convenience of subsequent overall plan adjustment. Therefore, there is a situation where the processed siphonic rainwater pipeline 1 is shorter than the length of the siphonic rainwater pipeline 1 analyzed from the actual collected data.

[0105] S3. Analyze the installation drawings of the preset siphonic rainwater pipe 1 to obtain the installation scenario of the siphonic rainwater pipe 1;

[0106] The installation scenario of the siphonic rainwater pipe 1 includes setting part of the siphonic rainwater pipe 1 inside the steel pipe column 3 and installing part of the siphonic rainwater pipe 1 inside the curtain wall column 2.

[0107] There is also the installation of some local siphonic rainwater pipes 1 that is the same as the installation method in the prior art. This patent does not improve it, and it belongs to the prior art, so it will not be described in detail.

[0108] S4. Construct the siphonic rainwater pipe 1 according to the installation scenario, and set part of the siphonic rainwater pipe 1 inside the curtain wall column 2 and the steel pipe column 3.

[0109] The present invention provides a method for installing siphonic rainwater pipes inside curtain wall columns and steel pipe columns, which solves the problems that the pipeline layout in an obvious position affects the aesthetics and is convenient for construction, and conflicts with the pipeline installation construction specifications. It has good use effects and has a good application prospect.

[0110] The present invention provides a method for installing siphonic rainwater pipes inside curtain wall columns and steel pipe columns, which optimizes the design and accurately positions. The system is optimized in design, and the length and butt joints of each section of the pipeline are precisely calculated to ensure the accurate butt joint of each section of the pipeline, which can increase the usable space of the building, reduce the decoration cost. The pipeline is installed inside the curtain wall column 2, effectively saving the usable space of the building, having good use effects and having a good application prospect.

[0111] As Figure 8 shown, the steps of setting part of the siphonic rainwater pipe 1 inside the steel pipe column 3 are as follows:

[0112] Construction preparation, formulating the scheduling plan for materials, personnel and tools;

[0113] After transporting the processed steel pipe column 3 to the installation position, install the support of the steel pipe column 3;

[0114] Perform anti-corrosion treatment on the pipeline inside the steel pipe column 3 and temporarily fix the pipeline inside the steel pipe column 3;

[0115] Weld the pipeline inside the steel pipe column 3;

[0116] Perform a water tightness test on the pipeline inside the steel pipe column 3. The water tightness test is mainly to avoid the situation of rainwater leakage affecting relevant structures;

[0117] After the hoisting of the steel pipe column 3 is completed, personnel enter the steel pipe column 3;

[0118] Manually inspect the pipeline inside the steel pipe column 3;

[0119] Perform anti-corrosion treatment on all welded joints. This technology enables the pipeline to be used for a long time, with good overall use effect and good application prospects.

[0120] Fix the pipeline. The pipeline is fixed by using existing pipeline connection methods. This patent does not make improvements in the final pipeline fixing aspect, so no more description will be given.

[0121] Since the siphonic rainwater pipeline 1 has been tested when leaving the factory, its quality can meet the requirements. Therefore, no tests are required in the early stage, and tests can be carried out after installation.

[0122] During the construction process, the siphonic rainwater pipeline 1 will be processed and there may be collisions of the siphonic rainwater pipeline 1, which will cause damage to the siphonic rainwater pipeline 1. Therefore, after construction, re-tests must be carried out. To ensure safety, further inspections are still required after the tests. Usually, manual inspection methods are used to achieve the inspection of the siphonic rainwater pipeline 1.

[0123] The installation of the siphonic rainwater pipeline 1 inside the steel pipe column 3 is very convenient. First, weld the angle iron brackets to the steel pipe column 3 and temporarily fix the pipeline in sections. Next, use argon arc welding to weld the joints of the sectional pipelines. Then, carry out the water tightness test inside the steel pipe column 3. Subsequently, the installation personnel enter the steel pipe column 3 for inspection. After inspection, if there are no problems, anti-corrosion treatment and fixation are carried out on the steel pipe column 3 to complete the installation of the siphonic rainwater pipeline 1 inside the steel pipe column 3.

[0124] As Figure 7 shown, after the hoisting of the steel pipe column 3 is completed, a camera device can also enter the pipeline inside the steel pipe column 3, photograph the inner wall of the pipeline, and transmit the photographed data to the computer to identify whether there are defects inside the pipeline based on the pipeline defect recognition algorithm.

[0125] The steps for installing part of the siphonic rainwater pipeline 1 inside the curtain wall column 2 are as follows:

[0126] Construction preparation, formulate the scheduling plan for materials, personnel and tools, so as to quickly realize the installation of the siphonic rainwater pipeline 1;

[0127] Weld the corresponding processed pipelines. Before welding the pipelines, it is necessary to detect the ends of the pipeline welding. When the ends of the pipeline are uneven, the uneven ends need to be removed and then welding can be carried out.

[0128] Perform anti-corrosion treatment on the welded pipelines. The anti-corrosion scheme adopted is the same as the existing anti-corrosion technology, which belongs to the common knowledge of those skilled in the art, so no more description will be given;

[0129] The end of the pipeline is closed with a blind end plate, and then a water tightness test is carried out. When defects are found in the water tightness test, further inspection and maintenance are required to eliminate the defects.

[0130] Place the qualified pipeline in the curtain wall column 2.

[0131] Weld angle iron brackets in the curtain wall column 2.

[0132] Fix the pipeline with U-shaped clamps in the curtain wall column 2.

[0133] The angle iron brackets and U-shaped clamps cooperate with each other, so that the overall installation of the siphonic rainwater pipeline 1 is more stable, effectively avoiding the loosening of the siphonic rainwater pipeline 1 in the later stage.

[0134] Connect the upper and lower ends of the pipeline in the curtain wall column 2 to the horizontal pipeline to complete the installation of part of the siphonic rainwater pipeline 1 in the curtain wall column 2.

[0135] In this embodiment, the connection of the pipelines is mainly carried out by welding.

[0136] Before welding the pipeline, the end of the pipeline is cut by plasma cutting, and then argon arc welding is used for welding the stainless steel pipeline.

[0137] The material of the siphonic rainwater pipeline in this embodiment is stainless steel pipeline.

[0138] The present invention provides a method for installing a siphonic rainwater pipeline in a curtain wall column and a steel pipe column. Before welding the pipeline, the end of the pipeline is cut by plasma cutting, and then argon arc welding is used for welding the stainless steel pipeline. The welding quality is high and it has good application prospects.

[0139] The installation of the siphonic rainwater pipeline 1 in the curtain wall column 2 is very convenient. Just weld the siphonic rainwater pipeline 1 by argon arc welding outside in advance, conduct a water tightness test outside, apply anti-corrosion to the pipeline, pass the welded siphonic rainwater pipeline 1 through the curtain wall column 2, weld angle iron brackets in the curtain wall column 2 through the reserved holes, fix the siphonic rainwater pipeline 1 to the angle iron brackets with U-shaped clamps, and at the same time connect the upper and lower ends to the siphonic rainwater horizontal pipeline to complete the installation of the siphonic rainwater pipeline 1 in the curtain wall column 2.

[0140] The present invention provides a method for installing a siphonic rainwater pipeline in a curtain wall column and a steel pipe column, reducing the cross-construction during the hoisting of the steel column, effectively ensuring safety, not affecting the hoisting time of the steel column, having little impact on the construction period, and being able to well guarantee the welding quality of the pipeline. Moreover, the siphonic rainwater pipeline 1 is concealed, enhancing the aesthetic feeling of the building, with good use effect and good application prospects.

[0141] The present invention provides a method for installing siphonic rainwater pipes inside curtain wall columns and steel pipe columns. The described solution installs part of the siphonic rainwater pipes 1 inside the steel pipe columns 3 and curtain wall columns 2. The situation of installing the siphonic rainwater pipes 1 inside the steel pipe columns 3 and curtain wall columns 2 will become a mainstream practice, making the designed siphonic rainwater pipes 1 aesthetically pleasing and convenient for construction, and preventing conflicts with the pipeline installation construction specifications.

[0142] In the application, several formulas involved are calculated by taking their numerical values after dimensionless treatment. The establishment of the formulas is obtained by collecting a large amount of data for software simulation to get a formula closest to the actual situation. Some coefficients or weights in the formulas are set by those skilled in the art according to the actual situation, so no more details will be given here.

[0143] The above embodiments can be implemented in whole or in part by software, hardware, firmware or any other combination. When implemented using software, the above embodiments can be implemented in whole or in part in the form of a computer program product. Those of ordinary skill in the art can realize that the units and algorithm steps of each example described in combination with the embodiments disclosed herein can be implemented by electronic hardware, or a combination of computer software and electronic hardware. Whether these functions are executed in a hardware or software manner depends on the specific application and design constraints of the technical solution.
