Description

Technical Field

[0001] This invention relates to the field of basement construction management technology, specifically to a construction management system for basement sidewalls based on grooved formwork. Background Technology

[0002] In recent years, large-scale underground projects and extra-long basement side walls have gradually increased. When the length of the basement side wall is too long, the total shrinkage value of the concrete is large. When the shrinkage is constrained by the hardened concrete base slab, the wall will crack. These cracks are mainly vertical, with a large width, and are difficult to repair and cannot be completely cured, thus becoming a common quality problem.

[0003] Therefore, solving and preventing cracking of basement side walls is urgent. The best method is to release stress in advance. This invention proposes a construction management system for basement side walls based on grooved templates. During the basement construction process, grooved templates are used to groove the inner surface of the side walls, releasing stress in advance and allowing for timely adjustment and management of the grooved strips to reduce the occurrence of cracks. This system has advantages such as improving project quality, saving repair costs, and shortening the construction period. Summary of the Invention

[0004] The purpose of this invention is to provide a construction management system for basement sidewalls based on grooved formwork, and to solve the following technical problems:

[0005] How to release stress in advance and adjust and manage the pressure groove strip in a timely manner to reduce the occurrence of cracks, while improving project quality, saving repair costs, and shortening the construction period.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A construction management system for basement sidewalls based on grooved formwork includes:

[0008] A grooved template, comprising a grooved strip and a side wall template, wherein one grooved strip divides the side wall cast based on the side wall template into a first section and a second section along the longitudinal direction; the grooved strip is composed of a fixed strip and a movable strip; the first section is adjacent to the fixed strip, and the second section is adjacent to the movable strip; the fixed strip is fixed to the side wall template, and the movable strip is movably connected to the fixed strip; the direction of movement of the movable strip is from the movable strip to the fixed strip.

[0009] The monitoring module monitors the completed sidewall and acquires monitoring data, including the external wall temperature, sidewall temperature, and sidewall humidity.

[0010] The analysis module analyzes the monitoring data to obtain the sidewall condition coefficient. The sidewall condition coefficient is directly proportional to the temperature change index and the humidity change index.

[0011] The control module controls the movement of the movable bar of the pressure groove bar based on the acquired sidewall state coefficient.

[0012] The above technical solution provides a construction management scheme based on a novel grooved template. The novel grooved template consists of a side wall template and grooved strips. The grooved strips are configured with two parts: a fixed strip and a movable strip. The movable strips are controlled by a control module and can be adjusted in position according to the side wall state coefficients obtained by the monitoring and analysis modules. This provides a larger stress release space for side wall areas with poor stress release, ensuring the stress release effect of the side wall, reducing the occurrence of cracks, and enhancing the quality of the project.

[0013] As a further technical solution of the present invention: the process of obtaining the sidewall state coefficient includes:

[0014] For the current monitoring day, the formula is as follows:

[0015]

[0016] Obtain the sidewall condition coefficient for the current monitoring day. ,in This is the temperature change index for the day. The humidity change index for the day. , C is a constant term, N is the number of monitoring time points per monitoring day, and k is the number of days after the sidewall was poured. It is the number of monitoring time points out of N monitoring time points whose monitored values ​​are judged to be normal, and .

[0017] The above technical solution provides a process for obtaining the sidewall condition coefficient. This invention obtains the sidewall condition coefficient based on a bivalent function model. The temperature change index and humidity change index are always positive. By adjusting the coefficient terms in the form of a determinant, the sidewall condition coefficient is made to be directly proportional to both the temperature change index and the humidity change index. That is, the greater the temperature or humidity change during the monitoring period, the greater the sidewall condition coefficient, and the less satisfactory the stress release effect of the wall is. Therefore, based on the condition coefficient, the pressure groove strip is adjusted in a timely manner when the stress release effect of the wall is not satisfactory, providing a larger stress release space for the sidewall area with poor stress release and ensuring the stress release effect of the sidewall.

[0018] As a further technical solution of the present invention: the process of obtaining the temperature change index and humidity change index includes:

[0019] N monitoring time points are selected and numbered for each monitoring day. For the k-th monitoring day, the measured values ​​of the monitoring values ​​of the first and second zones at the N monitoring time points are obtained.

[0020] A sidewall monitoring value change model was established for the first and second zones after pouring, and the predicted value of the monitoring value at each monitoring time point of the first and second zones was obtained based on the sidewall monitoring value change model.

[0021] Based on the first difference between the measured value and the predicted value, it is determined whether the monitoring values ​​corresponding to the first and second zones are abnormal. If the current monitoring value is determined to be abnormal, the second difference between the external wall temperature at the current monitoring time point and the ambient temperature of the corresponding side wall temperature change model is obtained, and the second difference is set as the adjustment coefficient of the monitoring value.

[0022] If the monitored value is determined to be abnormal, the monitored value will be adjusted according to the adjustment coefficient; otherwise, no adjustment will be made.

[0023] The above technical solution provides a process for obtaining temperature change index and humidity change index. Before obtaining the temperature change index and humidity change index, the data needs to be screened. The purpose of screening is to remove some abnormal data and supplement the removed data. By screening and replacement, the reliability of the data is improved, which facilitates subsequent data analysis.

[0024] As a further technical solution of the present invention: the process of adjusting the monitoring value according to the adjustment coefficient includes:

[0025] Set critical threshold If the second difference The adjustment factor is then set as follows:

[0026] ;

[0027] If the second difference If so, the adjustment coefficient output is 0;

[0028] The adjusted monitoring value output is ;

[0029] Where z is the adjustment coefficient. Let be a function to determine positive or negative signs. If the value is positive, the output is 1; otherwise, the output is -1. and These are two adjacent monitoring values ​​with the same serial number that are judged to be normal.

[0030] The above technical solution provides a process for adjusting monitoring values. The monitoring value adjustment process of the present invention requires a second judgment. When the monitoring value is abnormal and the second difference exceeds the critical threshold, the adjustment is made positively or negatively according to the abnormal situation. Compared with the traditional interpolation method, the adjustment process is more accurate and more adaptable to the construction process.

[0031] As a further technical solution of the present invention: the process of obtaining the temperature change index includes:

[0032] Based on the temperature data from the monitoring, a temperature change curve is obtained by fitting the temperature value at each monitoring time point. For day k, the formula is used:

[0033] ;

[0034] Obtain the temperature change index Where k is the number of days after the side wall is poured. It is the temperature change curve of the first partition at the i-th monitoring time point obtained by fitting. It is the temperature change curve of the i-th monitoring time point in the second partition obtained by fitting, where i is a non-zero positive integer not greater than k. and These are the preset first weighting coefficient and the second weighting coefficient, respectively.

[0035] The above technical solution provides a process for obtaining the temperature change index. The temperature change index of this invention is calculated based on the temperature data at each monitoring time point. Since the sampling time of each monitoring time point is close, it can better reflect the temperature change status of the sidewall. In addition, by using a weighted division method, the influence ratio of temperature change in the second zone is increased. Considering that the active bar mainly affects the second zone, it can ensure that the second zone can be detected in a timely manner when stress release is required.

[0036] As a further technical solution of the present invention: the process of obtaining the humidity change index includes:

[0037] Based on the humidity data from the monitoring, the humidity value at each monitoring time point is set as the average of the humidity in the first and second zones. A humidity change curve is obtained by fitting the humidity values ​​at each monitoring time point. For day k, the formula is used:

[0038]

[0039] Obtain the humidity change index ,in, is the humidity change curve of the sidewall at the i-th monitoring time point obtained by fitting, and j is a non-zero positive integer not greater than k.

[0040] As a further technical solution of the present invention: the process of controlling the movement of the movable strip of the pressure groove strip according to the obtained sidewall state coefficient includes:

[0041] Set standard value and critical days And obtain the ratio of the sidewall condition coefficient to the standard value. ;

[0042] like and If the moving bar is not adjusted, the movable bar of the grooved bar should be adjusted so that it moves 0.05mm parallel to the fixed bar; otherwise, the grooved bar should not be adjusted.

[0043] As a further technical solution of the present invention: the movable strip has a T-shaped structure, the fixed strip has a concave structure, the movable strip can be inserted into the groove of the concave structure of the fixed strip, a transmission component is provided between the fixed strip and the movable strip, the transmission component includes a first rotating rod rotatably disposed on the fixed strip, a second rotating rod is also disposed in the fixed strip, a worm gear is disposed on the first rotating rod, a worm wheel that cooperates with the worm gear is disposed on the second rotating rod, a threaded rod is disposed on the first rotating rod, and the threaded rod is threadedly connected to the movable strip.

[0044] As a further technical solution of the present invention: the groove strip is vertically installed on the inner surface of the basement side wall. The length of the groove strip is the net height of the basement minus 400mm. A 200mm gap is left between the top and bottom ends and the structural beam. The thickness of the groove strip is the same as the thickness of the side wall formwork. The thickness of the groove strip does not exceed the thickness of the protective layer of the wall. The width of the groove strip is between 45-55mm. The groove strip is installed at least once every 15 meters.

[0045] The beneficial effects of this invention are:

[0046] The novel grooved template of the present invention consists of a side wall template and a grooved strip. The grooved strip is configured as a fixed strip and a movable strip. The movable strip is controlled by the control module and can adjust its position according to the side wall state coefficient obtained by the monitoring module and the analysis module. This provides a larger stress release space for side wall areas with poor stress release, ensures the stress release effect of the side wall, reduces the occurrence of cracks, and enhances the quality of the project.

[0047] This invention obtains the sidewall condition coefficient based on a bivalent function model. The temperature change index and humidity change index are always positive. By adjusting the coefficient terms in the form of a determinant, the sidewall condition coefficient is made to be directly proportional to both the temperature change index and the humidity change index. That is, the greater the temperature or humidity change during the monitoring period, the greater the sidewall condition coefficient, and the less satisfactory the stress release effect of the wall is. Therefore, based on the condition coefficient, the pressure groove strip is adjusted in time when the stress release effect of the wall is not satisfactory, providing a larger stress release space for the sidewall area with poor stress release and ensuring the stress release effect of the sidewall.

[0048] Before acquiring the temperature change index and humidity change index of this invention, the data needs to be screened. The purpose of screening is to remove some abnormal data and supplement the removed data. By screening and replacement, the reliability of the data is improved, which facilitates subsequent data analysis.

[0049] The monitoring value adjustment process of this invention requires a second judgment. When the monitoring value is abnormal and the second difference exceeds the critical threshold, the adjustment is made positively or negatively according to the abnormal situation. Compared with the traditional interpolation method, the adjustment process is more accurate and more adaptable to the construction process.

[0050] The temperature change index of this invention is calculated based on the temperature data at each monitoring time point. Since the sampling time of each monitoring time point is similar, it can better reflect the temperature change status of the sidewall. In addition, by using a weighted division method, the influence ratio of temperature change in the second zone is increased. Considering that the active bar mainly affects the second zone, it can ensure that the second zone can be detected in a timely manner when stress release is required.

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Please see Figures 1-4 As shown, in one embodiment, a construction management system for basement sidewalls based on grooved formwork is provided, including:

[0061] The grooved template consists of a grooved strip 20 and a side wall template 10. A grooved strip 20 divides the side wall cast based on the side wall template into a first section and a second section along the longitudinal direction. The grooved strip 20 is composed of a fixed strip 21 and a movable strip 22. The first section is adjacent to the fixed strip 21, and the second section is adjacent to the movable strip 22. The fixed strip is fixed to the side wall template, and the movable strip 22 is movably connected to the fixed strip 21. The direction of movement of the movable strip 22 is from the movable strip 22 to the fixed strip 21.

[0062] The monitoring module monitors the completed sidewall and acquires monitoring data, including the external wall temperature, sidewall temperature, and sidewall humidity.

[0063] The analysis module analyzes the monitoring data to obtain the sidewall condition coefficient. The sidewall condition coefficient is directly proportional to the temperature change index and the humidity change index.

[0064] The control module controls the movement of the movable bar 22 of the pressure groove bar 20 based on the acquired side wall state coefficient.

[0065] This embodiment provides a construction management scheme based on a novel grooved template. The novel grooved template of this invention consists of a side wall template and grooved strips. The grooved strips are configured as two parts: a fixed strip and a movable strip. The movable strips are controlled by a control module and can be adjusted in position according to the side wall state coefficients obtained by the monitoring module and the analysis module. This provides a larger stress release space for side wall areas with poor stress release, ensuring the stress release effect of the side wall, reducing the occurrence of cracks, and enhancing the quality of the project.

[0066] The process of obtaining the sidewall state coefficients includes:

[0067] For the current monitoring day, the formula is as follows:

[0068]

[0069] Obtain the sidewall condition coefficient for the current monitoring day. ,in This is the temperature change index for the day. The humidity change index for the day. , C is a constant term, selected based on the construction scale; N is the number of monitoring time points per monitoring day; and k is the number of days after the sidewall is poured. It is the number of monitoring time points out of N monitoring time points whose monitored values ​​are judged to be normal, and .

[0070] This embodiment provides a process for obtaining the sidewall state coefficient. The present invention obtains the sidewall state coefficient based on a bivalent function model. The temperature change index and humidity change index are always positive. By adjusting the coefficient terms in the form of a determinant, the sidewall state coefficient is made to be directly proportional to both the temperature change index and the humidity change index. That is, the greater the temperature change or humidity change during the monitoring period, the greater the sidewall state coefficient, and the less satisfactory the stress release effect of the wall is. Therefore, based on the state coefficient, the pressure groove strip is adjusted in time when the stress release effect of the wall is not satisfactory, providing a larger stress release space for the sidewall area with poor stress release and ensuring the stress release effect of the sidewall.

[0071] The process of obtaining the temperature change index and humidity change index includes:

[0072] N monitoring time points are selected and numbered for each monitoring day. For the k-th monitoring day, the measured values ​​of the first and second zones of the N monitoring time points are obtained. The monitored values ​​include temperature and humidity. The numbering of the monitoring points is related to the time sequence of the monitoring points. That is, the first monitoring time point obtained on the k-th monitoring day is monitoring time point 1, and the last monitoring time point is monitoring time point N.

[0073] Models for the changes in sidewall monitoring values ​​after pouring are established for the first and second zones respectively. Based on the sidewall monitoring value change models, the predicted values ​​of the monitoring values ​​at each monitoring time point in the first and second zones are obtained. The monitoring value change models can be constructed using simulation software. There are no restrictions on the software used, but simulation software with high accuracy is preferred.

[0074] Based on the first difference between the measured value and the predicted value, it is determined whether the corresponding monitoring values ​​of the first and second zones are abnormal. The judgment result includes normal and abnormal. If the current monitoring value is determined to be abnormal, the second difference between the external wall temperature at the current monitoring time point and the ambient temperature of the corresponding side wall temperature change model is obtained, and the second difference is set as the adjustment coefficient of the monitoring value.

[0075] If the monitored value is determined to be abnormal, the monitored value will be adjusted according to the adjustment coefficient; otherwise, no adjustment will be made.

[0076] This embodiment provides a process for obtaining the temperature change index and humidity change index. Before obtaining the temperature change index and humidity change index, the data needs to be screened. The purpose of screening is to remove some abnormal data and supplement the removed data. By screening and replacement, the reliability of the data is improved, which facilitates subsequent data analysis.

[0077] The process of adjusting the monitored values ​​based on the adjustment factor includes:

[0078] Set critical threshold The critical threshold value is set based on empirical data, usually between 7℃ and 15℃. If the second difference... The adjustment factor is then set as follows:

[0079] ;

[0080] If the second difference If so, the adjustment coefficient output is 0;

[0081] The adjusted monitoring value output is ;

[0082] Where z is the adjustment coefficient. Let be a function to determine positive or negative signs. If the value is positive, the output is 1; otherwise, the output is -1. and These are two adjacent monitoring values ​​with the same serial number that are judged to be normal. It should be noted that when the number of monitoring values ​​judged to be normal is insufficient or non-existent, the sidewall monitoring value change model needs to be adjusted.

[0083] This embodiment provides a process for adjusting the monitoring value. The monitoring value adjustment process of the present invention requires a second judgment. When the monitoring value is abnormal and the second difference exceeds the critical threshold, the adjustment is made positively or negatively according to the abnormal situation. Compared with the traditional interpolation method, the adjustment process is more accurate and more adaptable to the construction process.

[0084] The process of obtaining the temperature change index includes:

[0085] Based on the temperature data from the monitoring, a temperature change curve is obtained by fitting the temperature value at each monitoring time point. For day k, the formula is used:

[0086] ;

[0087] Obtain the temperature change index Where k is the number of days after the side wall is poured. It is the temperature change curve of the first partition at the i-th monitoring time point obtained by fitting. It is the temperature change curve of the i-th monitoring time point in the second partition obtained by fitting, where i is a non-zero positive integer not greater than k. and These are the preset first weighting coefficient and second weighting coefficient, respectively. and The value of is positively correlated with the area of ​​the first and second partitions, and is a constant. Generally speaking, The value ranges from 0.1 to 0.3. The value ranges from 0.5 to 0.8.

[0088] This embodiment provides a process for obtaining the temperature change index. The temperature change index of this invention is calculated based on the temperature data at each monitoring time point. Since the sampling time at each monitoring time point is close, it can better reflect the temperature change status of the sidewall. In addition, by using a weighted division method, the influence ratio of temperature change in the second zone is increased. Considering that the activity bar mainly affects the second zone, it can ensure that the second zone can be detected in a timely manner when stress release is required.

[0089] The process of obtaining the humidity change index includes:

[0090] Based on the humidity data from the monitoring, the humidity value at each monitoring time point is set as the average of the humidity in the first and second zones. A humidity change curve is obtained by fitting the humidity values ​​at each monitoring time point. For day k, the formula is used:

[0091]

[0092] Obtain the humidity change index ,in, is the humidity change curve of the sidewall at the i-th monitoring time point obtained by fitting, and j is a non-zero positive integer not greater than k.

[0093] The process of controlling the movement of the movable strip of the pressure groove strip based on the obtained sidewall condition coefficient includes:

[0094] Set standard value and critical days And obtain the ratio of the sidewall condition coefficient to the standard value. The standard value and critical days are set based on empirical data. The standard value is related to the construction process and usually ranges from 3 to 12. The critical days are the number of days the side wall is initially solidified. They are related to the construction process and the size of the side wall. The larger the volume of the side wall, the larger the critical days.

[0095] like and If the moving bar 22 of the groove bar 20 is adjusted, the moving bar should be moved 0.05mm parallel to the fixed bar. Otherwise, the groove bar should not be adjusted.

[0096] The movable bar 22 has a T-shaped structure, and the fixed bar 21 has a concave structure. The movable bar 22 can be inserted into the groove of the concave structure of the fixed bar 21. A transmission component is provided between the fixed bar 21 and the movable bar 22. The transmission component includes a first rotating rod 23 rotatably mounted on the fixed bar 21. A second rotating rod 24 is also provided inside the fixed bar 21.

A threaded rod is provided on the first rotating rod 23, and the threaded rod is threadedly connected to the movable bar 22.

[0097] The groove strip 20 is vertically installed on the inner surface of the basement side wall. The length of the groove strip 20 is the clear height of the basement minus 400mm. A 200mm gap is left between the top and bottom ends and the structural beam. The thickness of the groove strip 20 is the same as the thickness of the side wall formwork, generally 18mm.
