Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a method for controlling the straightness of a tall, irregularly shaped hyperboloid building. Background Technology

[0002] With the continuous advancement of technology, people have set higher standards for their living standards, leading to dramatic changes in life and significant progress across all industries, including the ubiquitous architectural design industry. In the information age, architectural design has gradually become more "complex," and this "complexity" often stems from people's high standards and demands. For example, the pursuit of aesthetics has led to requirements for the form of buildings, and the pursuit of comfort has led to requirements for the spatial experience. The concept of "complexity" design did not appear out of thin air; rather, it is the result of a series of summaries and analyses by experts, utilizing the actual environment to upgrade buildings and better meet people's needs. This "complexity" design concept has numerous advantages and will become a major development direction for future architectural design.

[0003] For complex double-shell structures with varying curvature and irregular hyperboloid fair-faced concrete, the design requires that the curvature of each part of the double-shell structure be different, and that there be only one 50m high and 62m long oblique straight line to ensure that the control projection is a straight line at the spring and autumn equinoxes. This complex design effect requires high accuracy in the straight line of the aforementioned oblique straight line, but current construction methods do not have a straight line control technology for such complex double-shell structures with varying curvature. Summary of the Invention

[0004] In view of this, the present invention proposes a method for controlling the straightness of tall, irregularly shaped hyperboloid buildings, which can solve the problem of straightness control in fair-faced concrete buildings with tall, irregularly shaped hyperboloid structures.

[0005] This invention is implemented as follows:

[0006] This invention provides a method for controlling the straightness of the oblique curve of a tall, irregularly shaped hyperboloid building, comprising the following steps:

[0007] S10: Alloy profile side ribs are set at the outermost edge of the arch shell cover mold of the casting template to ensure that the end edge within the casting range is straight and the first casting section is cast.

[0008] S20: Wrap the upper part of the construction joint with the first pouring section by 5-10cm, and connect the lower end of the alloy profile side rib to the first pouring section by 1-2m. Place a template of the same thickness as the pouring template between the alloy profile side rib and the first pouring section, and connect the first pouring section and the alloy profile side rib vertically into a line.

[0009] S30: Attach a sponge strip to the first pouring section, attach a plastic film to the sponge strip to drain the water, and pour the second pouring section;

[0010] S40: Verify the straightness of the slope between the first pouring section and the second pouring section. If the straightness is within the allowable deviation range, proceed to the next step. If the straightness exceeds the allowable deviation range, take remedial measures until the straightness is qualified.

[0011] S50: Repeat steps 20 to S40 until all pouring sections are completed;

[0012] S60: Verify the straightness of the slope between the first and last pouring sections. If the straightness is within the allowable deviation range, the pouring is completed. If the straightness exceeds the allowable deviation range, take repair measures until the straightness is qualified.

[0013] The technical effects of the method for controlling the straightness of tall, irregularly shaped hyperboloid buildings provided by this invention are as follows: This method utilizes the straightness and resistance to deformation of the alloy profile ribs to ensure that the formwork of adjacent concrete pouring sections does not bend during concrete pouring. Combined with the method of wrapping the formwork around the upper pouring section, it further ensures the straightness between adjacent pouring sections and promotes a tight connection between them. By using a plastic film for drainage, it effectively guides the water released from the lower concrete layer to flow outwards, avoiding water accumulation and ensuring the homogeneity and quality of the newly poured concrete. Through this method, the slope of each pouring section can be monitored in real time during the construction of tall, irregularly shaped hyperboloid buildings to ensure compliance with predetermined standards. It also solves the current industry problem of lacking a straightness control technology for high-complexity, variable-curvature, double-shell structure fair-faced concrete buildings, ensuring that straight lines are smoothly and seamlessly integrated into the main body of the tall, irregularly shaped hyperboloid building.

[0014] Based on the above technical solution, the method for controlling the oblique straightness of a tall, irregularly shaped hyperboloid building according to the present invention can be further improved as follows:

[0015] Specifically, step S40, verifying the straightness between the first pouring segment and the second pouring segment, includes the following steps:

[0016] Step 1: Cast the shell sample of the first casting section in proportion. Set up a target on the shell sample and monitor the deformation curve of the first casting section under the influence of temperature and humidity in real time by deformation monitoring radar to obtain the influence factors of temperature and humidity on the deformation of the casting section.

[0017] The second step is to select measurement points on the first and second pouring sections. The measurement points should be distributed on the surface of the two adjacent pouring sections to be controlled to ensure the accuracy and reliability of the measurement values.

[0018] The third step is to install a straightness error detection device between the two measurement points to be measured.

[0019] Step 4: Measure the real-time straightness between the first pouring section and the second pouring section, and calculate the actual straightness between the first pouring section and the second pouring section in combination with the deformation influence factor.

[0020] The deformation influence factor is used because concrete undergoes a certain amount of deformation under the influence of factors such as temperature, humidity, and even material deformation, which can lead to deviations in the measured straightness. Introducing the deformation influence factor when measuring the straightness of the inclined section can promptly detect whether the straightness of the concrete structure is actually within acceptable limits or falsely exceeds the tolerance, thereby improving the accuracy of the straightness measurement. This helps construction personnel to identify problems in a timely manner and take measures to ensure construction safety and the quality of concrete structures.

[0021] Furthermore, the straightness error detection device includes a sliding bracket and two sliders disposed on the rear side of the sliding bracket. Guide bosses are slidably connected within each slider. The guide bosses are perpendicular to the sliding bracket, and a straight base plate is disposed on the rear side of each guide boss. A displacement sensor is installed at the middle of the rear side of the sliding bracket. The displacement sensor is electrically connected to a processor. A long groove is formed in the middle of the sliding bracket, and multiple probes are installed within the long groove. A detection head is disposed below each probe, and the detection head can contact the corresponding concrete surface below. Each probe is electrically connected to the processor, and the processor is also electrically connected to a computer.

[0022] Furthermore, the probe also includes a housing, within which a sliding sleeve is coaxially mounted. A first limiting block and a second limiting block are disposed between the sliding sleeve and the housing, and a guide sleeve is disposed between the first limiting block and the second limiting block. The cylindrical end of the detection head is coaxially mounted inside the bottom of the sliding sleeve, and the contact end of the detection head protrudes below the sliding sleeve. A pressure plate is installed inside the top of the sliding sleeve, and a first spring is installed between the pressure plate and the top wall of the sliding sleeve. A second spring is sleeved on the outer wall of the sliding sleeve, located between the first limiting block and the second limiting block, with both ends of the second spring abutting against the first limiting block and the second limiting block, respectively. An upper end cover and a lower end cover are respectively installed on the upper and lower end faces of the housing. A plug is coaxially mounted in the central hole of the upper end cover, and a contact is installed on the plug located inside the housing. The contact is used to contact the pressure plate inside the sliding sleeve after the sliding sleeve moves upward.

[0023] When a detection head contacts the concrete surface, the detection head moves the sliding sleeve upward, causing the contact point to contact the pressure plate and generate an electrical signal. The contact point then compresses the first spring and enters the sliding sleeve to prevent over-contact.

[0024] Furthermore, the displacement sensor is a grating linear displacement sensor or a magnetic linear displacement sensor.

[0025] The processor is an LPC11C24 processor.

[0026] Furthermore, the verification of the straightness between the first and last pouring sections in step S50 specifically includes the following steps:

[0027] Step 1: Select the measurement points on the first pouring section and the last pouring section as test points;

[0028] The second step is to install a laser rangefinder at the measurement point of the first pouring section; and to install a reflector at the test point of the last pouring section.

[0029] The third step is to use the laser rangefinder to measure the distance between the first pouring section and the last pouring section, and to calculate the straightness of the slope.

[0030] Furthermore, the laser rangefinder includes a laser emitting module, a laser receiving module, a transceiver common path module, and a computing module;

[0031] The laser emitting module is used to emit an initial laser signal to the reflector;

[0032] The laser receiving module is used to receive the reflected laser signal reflected back by the reflector.

[0033] The transceiver common path module includes a first transmission channel and a second transmission channel, used to obtain a broadband light source based on the initial laser signal, to illuminate the reflector plate with the broadband light source through the first transmission channel, and to collect the reflected laser signal received by the laser receiving module through the second transmission channel;

[0034] The calculation module is used to calculate the time difference based on the time of emitting the initial laser signal and the time of receiving the reflected laser signal, and then calculate the distance between the reflector and the laser rangefinder.

[0035] The transceiver module is electrically connected to the laser emitting module and the laser receiving module, respectively, and the computing module is electrically connected to the laser emitting module, the laser receiving module, and the transceiver module, respectively.

[0036] The beneficial effects of adopting the above-mentioned improved scheme are as follows: By setting up a common transceiver module, and utilizing the flexible and configurable length characteristics of optical fiber, long-distance laser ranging can be achieved, which is suitable for tall, irregularly shaped hyperboloid buildings. Fiber optic transmission has the characteristics of low requirements for the installation environment and can work in complex conditions such as narrow, uneven, repeatedly bent, blocked, humid, submerged, sealed, electromagnetic interference, and radiation, which helps to reduce ranging errors and improve the accuracy of measuring the straightness of tall, irregularly shaped hyperboloid buildings. At the same time, by utilizing the wide spectral characteristics of the light source, rapid ranging of points on a single line in space can be achieved at the same time, improving measurement speed and efficiency.

[0037] Furthermore, the transceiver common path module specifically includes: an all-fiber transmission unit, a first collimation coupling unit, and a first dispersion unit; the all-fiber transmission unit includes a main fiber, the main fiber including the first transmission channel and the second transmission channel; the first collimation coupling unit is separated from the all-fiber transmission unit; the first dispersion unit is separated from the first collimation coupling unit.

[0038] The all-fiber transmission unit is used to obtain a broadband light source based on the initial laser signal, transmit the broadband light source from the main optical fiber through the first transmission channel, and receive the reflected laser signal reflected back after the broadband light source illuminates the reflector through the second transmission channel.

[0039] The first collimation coupling unit is used to collimate the broadband light source and couple the reflected laser signal so that the all-fiber transmission unit receives the reflected laser signal through the second transmission channel;

[0040] The first dispersion unit is used to disperse the collimated broadband light source so that the broadband light source illuminates the reflector.

[0041] Furthermore, the laser receiving module specifically includes: a second collimation coupling unit, a second dispersion unit, and a detection unit; the second collimation coupling unit is used to collimate the reflected laser signal; the second dispersion unit is used to diverge the collimated reflected laser signal; and the detection unit is used to receive the diverged reflected laser signal.

[0042] Furthermore, the laser emitting module is a semiconductor laser with a wavelength of 970nm to 980nm.

[0043] Compared with existing technologies, the beneficial effects of the method for controlling the straightness of tall, irregularly shaped hyperboloid buildings provided by this invention are as follows: This method utilizes the straightness and resistance to deformation of the alloy profile ribs to ensure that the formwork of adjacent concrete pouring sections does not bend during concrete pouring. Combined with the method of wrapping the formwork around the previous pouring section, it further ensures the straightness between adjacent pouring sections and promotes a tight connection between them. By introducing a deformation influence factor when measuring the straightness, it can promptly detect situations where the straightness of the concrete structure is falsely acceptable or exceeds the tolerance, improving the accuracy of straightness measurement and helping construction personnel to identify problems and take timely measures to ensure construction safety and the quality of the concrete structure. Through this method, the straightness of each pouring section can be monitored in real time during the construction of tall, irregularly shaped hyperboloid buildings to ensure compliance with predetermined standards. It also solves the current industry problem of lacking a straightness control technology for high-complexity, variable-curvature, double-shell structure fair-faced concrete buildings.

Therefore, they should not be construed as limitations on this invention.

[0056] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0057] like Figure 1 The diagram shows a flowchart of a method for controlling the oblique straightness of a tall, irregularly shaped hyperboloid building provided by this invention, which specifically includes the following steps:

[0058] S10: Alloy profile side ribs are set at the outermost edge of the arch shell cover mold of the casting template to ensure that the end edge within the casting range is straight and the first casting section is cast.

[0059] S20: Wrap the upper part of the construction joint with the first pouring section by 5-10cm, and connect the lower end of the alloy profile side rib to the first pouring section by 1-2m. Place a template of the same thickness as the pouring template between the alloy profile side rib and the first pouring section, and connect the first pouring section and the alloy profile side rib vertically into a line.

[0060] S30: Attach a sponge strip to the first pouring section, and attach a plastic film to the sponge strip to guide the flow, then pour the second pouring section;

[0061] S40: Verify the straightness of the slope between the first and second pouring sections. If the straightness is within the allowable deviation range, proceed to the next step. If the straightness exceeds the allowable deviation range, take remedial measures until the straightness is qualified.

[0062] S50: Repeat steps 20 to S40 until all pouring sections are completed;

[0063] S60: Verify the straightness of the slope between the first and last pouring sections. If the straightness is within the allowable deviation range, the pouring is complete. If the straightness exceeds the allowable deviation range, take remedial measures until the straightness is qualified.

[0064] It should be noted that alloy profile ribs are set at the outermost edge of the arch shell formwork. The profiles can remain straight and are not easily deformed. The height of the profiles is the same as the thickness of the ribs. The formwork at the external corners is treated with a mortise and tenon joint. The profiles connecting to the old wall of the first pouring section can ensure that the upper and lower concrete components will not bend. The pouring formwork at the construction joint is wrapped 5 cm down to hug the original wall of the first pouring section. The secondary ribs extend vertically or horizontally to a row of bolts on the completed wall. Tie bolts are used to fasten the formwork through the wall of the first pouring section to ensure that the formwork fits tightly to the wall of the first pouring section. When using membrane drainage, materials such as wire mesh can be added to the membrane to enhance its load-bearing capacity and strength, so as to better control the process of water release from the lower concrete.

[0065] In the above technical solution, step S40, verifying the straightness between the first and second pouring sections, specifically includes the following steps:

[0066] The first step is to cast a shell sample of the first casting section in proportion, set up targets on the shell sample, and monitor the deformation curve of the first casting section under the influence of temperature and humidity in real time through deformation monitoring radar to obtain the influence factors of temperature and humidity on the deformation of the casting section.

[0067] The second step is to select measurement points on the first and second pouring sections. The measurement points should be distributed on the surface of the two adjacent pouring sections to be controlled to ensure the accuracy and reliability of the measurement values.

[0068] The third step is to install a straightness error detection device between the two measurement points to be measured.

[0069] The fourth step is to measure the real-time straightness between the first and second pouring sections, and calculate the actual straightness between them in conjunction with the deformation influence factor.

[0070] In use, a deformation monitoring radar is set at the target of the shell sample. The deformation monitoring radar is used to monitor the concrete structure of the first pouring section in real time for multiple natural days. Combined with the actual temperature and humidity conditions of multiple natural days, the deformation curves of the first pouring section in different measurement environments are obtained. Then, the influence factors of temperature and humidity on the deformation of the pouring section are obtained. When pouring the next pouring section, the construction parameters are controlled in combination with the deformation influence factors of the pouring section. At the same time, when measuring the straightness of the adjacent pouring sections, the influence of the deformation influence factors on the straightness is considered to detect false compliance or false deviation of the inclination in a timely manner.

[0071] like Figure 2-4 As shown, further, in the above technical solution, the straightness error detection device includes a sliding bracket 10 and two sliders 11 disposed on the rear side of the sliding bracket 10. Guide bosses 12 are slidably connected in the sliders 11 respectively. The guide bosses 12 are perpendicular to the sliding bracket 10, and a straight substrate 13 is disposed on the rear side of the guide bosses 12. A displacement sensor 14 is installed at the middle position of the rear side of the sliding bracket 10. The displacement sensor 14 is electrically connected to the processor 20. A long groove is opened in the middle of the sliding bracket 10. Multiple probes 30 are installed in the long groove. A detection head 36 is disposed below the probes 30. The detection head 36 can contact the corresponding concrete surface below. The probes 30 are electrically connected to the processor 20 respectively. The processor 20 is also electrically connected to the computer 40.

[0072] In use, considering the straightness requirements of tall, irregularly shaped hyperboloid buildings, probes 30 are installed within the measurement length. Probes 30 are inserted from the front end of the sliding bracket 10 and are equidistantly set on the sliding bracket 10. The contacts 39 of the probes 30 are adjusted to be on the same straight line. The spacing of the points to be detected is adjusted by sliding the probes 30 in the long groove of the sliding bracket 10. After the probes 30 are installed, the standard position points on the concrete are first brought into contact with the contacts 39 of the probes 30. The set of position signals triggered by the contacts 39 of each probe 30 is stored in the storage unit of the processor 20. This set of position signals is the initial error set of the probes 30.

[0073] During testing, the sliding bracket 10 is manually moved along the guide boss 12, and multiple probes 30 installed on the same horizontal line approach the concrete surface. Multiple detection heads 36 will contact the feature points of the concrete surface in sequence, emit position data information sets, which are processed by the processor 20 to obtain position data after eliminating the initial error and draw the contour curve, which is displayed on the computer 40. The straightness error value of the concrete surface is detected by the minimum area method.

[0074] Furthermore, in the above technical solution, the probe 30 also includes a housing 31, within which a sliding sleeve 32 is coaxially mounted. A first limiting block 33 and a second limiting block 34 are provided between the sliding sleeve 32 and the housing 31, and a guide sleeve 35 is provided between the first limiting block 33 and the second limiting block 34. The cylindrical end of the detection head 36 is coaxially mounted inside the bottom of the sliding sleeve 32, and the contact end of the detection head 36 protrudes below the sliding sleeve 32. A pressure plate 37 is installed inside the top of the sliding sleeve 32, and a first spring 3 is installed between the pressure plate 37 and the top wall of the sliding sleeve 32. 71. A second spring 321 is sleeved on the outer wall of the sliding sleeve 32. The second spring 321 is located between the first limiting block 33 and the second limiting block 34, and the two ends of the second spring 321 abut against the first limiting block 33 and the second limiting block 34 respectively. An upper end cover 311 and a lower end cover 312 are respectively installed on the upper and lower end faces of the housing 31. A plug 38 is coaxially installed in the center hole of the upper end cover 311. A contact 39 is installed on the plug 38 located inside the housing 31. The contact 39 is used to contact the contact pressure piece 37 inside the sliding sleeve 32 after the sliding sleeve 32 moves upward.

[0075] In use, under the action of contact force, the detection head 36 drives the sliding sleeve 32 to move upward along the first limit block 33 and the second limit block 34 against the second spring 321, so that the contact 39 contacts the contact pressure plate 37 and sends out a trigger electrical signal. The trigger electrical signal sent by the contact 39 is transmitted to the processor 20 through the plug 38, so that the displacement pulse information received by the displacement sensor 14 by the processor 20 is interrupted and triggered. At the same time, the processor 20 collects these trigger position data and records them in the storage unit.

[0076] The trigger signal is connected to the input port of the processor 20, and the input port of the processor 20 is set to interrupt mode. The processor 20 has a built-in CAN bus transceiver and controller, and the internal 32-bit counter realizes the reception of the pulse signal of the displacement sensor 14. When a signal is triggered, the storage unit of the processor 20 records the displacement of the workpiece being tested at the detection point. As each probe 30 contacts the concrete surface in turn, the processor 20 collects and records the position information of each detection point.

[0077] Furthermore, in the above technical solution, the displacement sensor 14 is a grating line displacement sensor or a magnetic line displacement sensor.

[0078] Furthermore, in the above technical solution, step S50, verifying the straightness between the first and last pouring sections, specifically includes the following steps:

[0079] Step 1: Select measurement points on the first and last pouring sections as test points;

[0080] The second step is to install a laser rangefinder at the measurement point of the first pouring section; and to install a reflector at the test point of the last pouring section.

[0081] The third step is to use a laser rangefinder to measure the distance between the first and last pouring sections and to calculate the straightness of the slope.

[0082] like Figure 5 As shown, further, in the above technical solution, the laser rangefinder includes a laser emitting module, a laser receiving module, a transceiver common path module, and a computing module;

[0083] The laser emitting module is used to emit an initial laser signal toward the reflector;

[0084] The laser receiving module is used to receive the reflected laser signal that has been reflected back by the reflector.

[0085] The transceiver common path module includes a first transmission channel and a second transmission channel, which are used to obtain a broadband light source based on the initial laser signal, to illuminate the reflector plate through the first transmission channel, and to collect the reflected laser signal received by the laser receiving module through the second transmission channel.

[0086] The calculation module is used to calculate the time difference based on the time of emitting the initial laser signal and the time of receiving the reflected laser signal, and then calculate the distance between the reflector and the laser rangefinder.

[0087] The transceiver module is electrically connected to the laser emitting module and the laser receiving module, respectively, and the computing module is electrically connected to the laser emitting module, the laser receiving module, and the transceiver module, respectively.

[0088] In use, the laser emitting module emits a laser towards the reflector, while the transceiver module collects the initial laser signal. After the laser reaches the reflector, it is reflected, and the laser receiving module receives the reflected laser signal. At the same time, the transceiver module collects the reflected laser signal received by the laser receiving module and transmits it to the calculation module. The calculation module combines the time of emitting the initial laser signal and the time of receiving the reflected laser signal to calculate the time difference, and then calculates the distance between the test point of the first pouring section and the test point of the last pouring section.

[0089] Furthermore, in the above technical solution, the transceiver common path module specifically includes: an all-fiber transmission unit, a first collimation coupling unit, and a first dispersion unit; the all-fiber transmission unit includes a main fiber, and the main fiber includes a first transmission channel and a second transmission channel; the first collimation coupling unit is separated from the all-fiber transmission unit; the first dispersion unit is separated from the first collimation coupling unit.

[0090] Furthermore, in the above technical solution, the laser receiving module specifically includes: a second collimation coupling unit, a second dispersion unit, and a detection unit; the second collimation coupling unit is used to collimate the reflected laser signal; the second dispersion unit is used to diverge the collimated reflected laser signal; and the detection unit is used to receive the diverged reflected laser signal.

[0091] Furthermore, in the above technical solution, the laser emitting module is a semiconductor laser with a wavelength of 970nm to 980nm.

[0092] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
