Description

Technical Field

[0001] The invention relates to the technical field of construction equipment configuration, and in particular to a method for installing a hydraulic prefabricated assembly component. Background Art

[0002] Prefabricated buildings are the direction of future construction development. At present, the application of prefabricated components in civil engineering and transportation bridge projects is booming. Due to the special nature of the structure, the application of prefabricated components in hydraulic structures is very low. Traditional hydraulic building components mostly use cast-in-place concrete structures, which require a large amount of formwork materials during construction, and steel bar laying and building concrete must be carried out on site, which is time-consuming and labor-intensive, greatly affected by the environment, and has high construction costs. At the same time, many hydraulic concrete prefabricated prefabricated components are connected by steel bar connection and other methods, and then concrete is cast on site, which seriously affects the construction period, and the workload is large, the construction is complicated, and it is easy to cause quality problems, which is not conducive to ensuring the overall safety and quality of building prefabricated components.

[0003] Chinese patent publication number CN114592595 discloses a node connection device for hydraulic prefabricated assembled concrete components. By setting a connecting gear, a positioning gear and a connecting rack, the guide device can be quickly and accurately moved up on the outside of the concrete pillar, thereby facilitating the subsequent rapid and stable positioning operation of the concrete prefabricated parts. At the same time, the limiting gear ring and the connecting gear ring can drive the two sets of limiting devices to accurately position the concrete prefabricated parts through the limiting gear and the connecting screw rod, thereby improving the accuracy and stability of the installation and positioning of the concrete prefabricated parts. It can be seen that in the above technical scheme, the node connection device of the hydraulic prefabricated assembled concrete components has the following problems: the node connection device of the hydraulic prefabricated assembled concrete components has a complicated connection process, a high manufacturing cost, and high requirements for operators.

[0038] Furthermore, the central control module determines two types of adjustment methods for the leveling height of the subsequent construction plane according to the difference between the settlement depth of the component and the preset first settlement depth, wherein;

[0039] The first type of adjustment method is that the central control module adjusts the leveling height of the subsequent construction plane to the second leveling height under the preset third settlement depth difference condition;

[0040] The second type of adjustment method is that the central control module adjusts the embedded bolt holes under the preset third settlement depth difference condition to enhance the connection strength between the components and modify the offset angle.

[0041] Further, in step S4, the central control module determines whether the vibration intensity during transportation is within the allowable range according to the total connection length of the hydraulic prefabricated assembly components in two types of determination methods, wherein;

It is less affected by the external environment, shortens the construction period, and can still be completed normally during the rainy season.

[0050] Furthermore, the hydraulic prefabricated components to be installed include a plurality of hydraulic prefabricated assembled components. Installing a plurality of assembled components at one time can reduce the installation cost and make the installation process simpler.

[0051] Furthermore, the raised teeth and grooves are provided on the precast concrete teeth in the hydraulic prefabricated assembled components so that preliminary pre-fixation can be performed during the installation process, so that the horizontal angle that needs to be calibrated during the subsequent installation is small and the bolt fixing effect is more stable.

[0052] Furthermore, three judgment conditions are set for the settlement depth, with the aim of determining the cause of the settlement that affects stability, accurately determining the different causes of the settlement according to the different settlement depths, and making corrections accordingly.

[0053] Furthermore, different adjustment methods are formulated for different causes of settlement, so that the adjustment results are more accurate and the corresponding adjustment process is simpler.

[0054] Furthermore, different adjustment methods are set for the reasons of settlement caused by different connection strengths in order to reduce unnecessary adjustment steps. Only the embedded bolt holes of the components that must be adjusted are adjusted, making the adjustment process more efficient and accurate.

[0055] Furthermore, the total length of the prefabricated component connections is determined during transportation in order to determine whether the vibrations generated by the machine during transportation affect the connection stability of the prefabricated components, thereby avoiding insufficient stability of the connection due to direct installation.

[0056] Furthermore, the vibration intensity during transportation is adjusted by adjusting the speed of the power motor to achieve the effect of adjusting the stability during transportation, which is simpler and more effective than setting other adjustment methods.

[0068] Step S1, manufacturing the main body of the hydraulic prefabricated assembly component, determining the length of the embedded hole according to the length of the bolt during the manufacturing process, and casting the main body of the hydraulic prefabricated assembly component to form a single hydraulic prefabricated assembly component after the manufacturing is completed;

[0069] Step S2, leveling the reference installation plane of a single hydraulic prefabricated assembly component, determining the laying direction of the hydraulic prefabricated assembly component, installing the single hydraulic prefabricated assembly component as a reference to a specified position of the installation plane along the laying direction, using a settlement monitoring sensor to detect the horizontal settlement depth of the installation plane before and after installation with a preset settlement detection cycle, and the central control module adjusts the leveling height of the subsequent construction plane to a corresponding height according to the settlement depth of the hydraulic prefabricated assembly component;

[0070] Step S3, installing a component moving track along the laying direction, and installing a transfer frame as a reference transfer frame at a preset reference position of the hydraulic prefabricated assembly component serving as a reference;

[0071] Step S4, arranging a component transfer frame on the moving track, the component transfer frame moves on the moving track, transferring a single hydraulic prefabricated assembled component to be assembled to a first assembly position, and fixing the component transfer frame with a preset assembly position of the hydraulic prefabricated assembled component to be assembled to form an assembly transfer frame of the hydraulic prefabricated assembled component, and fixing the component transfer frame with a preset reference position of the hydraulic prefabricated assembled component to be assembled to form an assembly fixing frame of the hydraulic prefabricated assembled component;

[0072] Step S5, connecting the installed hydraulic prefabricated assembly component and the hydraulic prefabricated assembly component to be installed, and the central control module adjusts the length of the embedded hole to a corresponding length according to the inclination angle of the hydraulic prefabricated assembly component when the connection strength is initially determined to be lower than the allowable range;

[0073] Step S6, moving the reference transfer frame to a second assembly position, and fixing it as the assembly transfer frame of the subsequent hydraulic prefabricated assembly component and the preset assembly position of the subsequent hydraulic prefabricated assembly component;

[0074] Step S7, repeating steps S3 to S6 to perform transverse overlap of the next hydraulic prefabricated assembly component until all hydraulic prefabricated assembly components are integrated;

[0075] Wherein, the first assembly position is a reference position from the next hydraulic prefabricated assembly component; the preset assembly distance is a maximum distance at which the hydraulic prefabricated assembly component does not deform in a cantilevered state.

[0076] Compared with the prior art, the beneficial effects of the present invention lie in that the key points of the new type are simple construction procedures, simple construction operations, little impact of the external environment on the construction, shortened construction period, low requirements on operators and easy quality assurance, and there are very few component breakages, damages and the like. It is less affected by the external environment, shortens the construction period, and can still be completed normally during the rainy season.

[0077] Specifically, in step 5, the connection process of the installed hydraulic prefabricated assembled components and the hydraulic prefabricated components to be installed includes:

[0078] Step S51, placing the protruding portion of the frontmost precast concrete tooth of the hydraulic prefabricated component to be installed along the horizontal direction of the installed hydraulic prefabricated component to be vertically aligned above the concave portion of the precast concrete tooth groove of the installed hydraulic prefabricated component;

[0079] Step S52, buckle the hydraulic prefabricated assembled component to be installed into the hole according to the prefabricated concrete teeth to keep the overall stability of the component;

[0080] Step S53, insert high-strength bolts into the upper and lower four perforated steel columns respectively, and screw the high-strength bolts into the embedded holes to complete the connection.

[0081] The hydraulic prefabricated components to be installed include a plurality of hydraulic prefabricated assembled components. Installing a plurality of assembled components at one time can reduce the installation cost and make the installation process simpler.

[0082] See also Figures 3 to 5 As shown in the figure, the upper connection composite steel plate 1, the precast concrete member 2, the lower connection composite steel plate 3, the embedded hole 4, the upper precast concrete tooth 5, the lower precast concrete tooth 6, the arc steel plate 7, the steel column with holes 8, the stirrup 9, and the welded steel bar 10;

[0083] Specifically, the single hydraulic prefabricated assembly component includes: a plurality of connected combined steel plates, a prefabricated concrete body and a steel plate connection part,

[0084] The precast concrete body comprises a concrete component structure body, a precast concrete tooth arranged at a front end portion of the concrete component structure body in a transverse direction, and a precast concrete tooth groove arranged at a rear end portion of the concrete component structure body in a transverse direction;

[0085] The raised portion of the precast concrete tooth is arranged correspondingly to the recessed portion of the precast concrete tooth groove, the recessed portion is connected to the lower portion of the rear end surface of the concrete component structure body, the recessed portion is provided with two cylindrical grooves, and the raised portion is provided with two cylindrical raised teeth.

[0086] The steel plate connection part is arranged at the front end part of the concrete member structure body in the transverse direction, and the connection combination steel plate group includes two connection combination steel plates arranged along a first height level and two connection combination steel plates arranged along a second height level, wherein the first height is higher than the convex part, and the second height is lower than the groove bottom surface of the concave part;

[0087] The upper connection composite steel plate and the lower connection composite steel plate are welded to the welded steel bars at a fixed position, and the stirrups are welded to the welded steel bars to fix the upper connection composite steel plate, the lower connection composite steel plate and the welded steel bars;

[0088] Among them, in the precast concrete tooth, the axis of a single groove is perpendicular to the horizontal plane, the axis of a single raised tooth is perpendicular to the horizontal plane, the lower end surface of the raised tooth is lower than the upper end surface of the groove, and the cylindrical radius of the raised tooth is smaller than the cylindrical radius of the groove;

[0089] The purpose of setting raised teeth and grooves on the precast concrete teeth in hydraulic prefabricated assembled components is to perform preliminary pre-fixation during the installation process, so that the horizontal angle required for subsequent installation is small and the bolt fixing effect is more stable;

[0090] It is understandable that the raised tooth shape and the corresponding recessed shape provided in the present invention are not unique, and the purpose is to preliminarily pre-fix two hydraulic prefabricated assembled components with concrete teeth, and other raised tooth shapes and corresponding recessed shapes that can achieve this function can be used instead.

[0091] Specifically, in step S2, the central control module determines whether the installation stability is within the allowable range according to the settlement depth of the prefabricated component in three types of determination methods, wherein:

[0092] The first determination method is that the central control module determines that the stability of the installation is within the allowable range under the condition of a preset first settlement depth;

[0093] The second determination method is that the central control module determines that the installation stability is lower than the allowable range under the preset second settlement depth condition, and adjusts the leveling height of the subsequent construction plane to the corresponding height by calculating the difference between the settlement depth of the component and the preset first settlement depth;

[0094] The third determination method is that the central control module determines that the stability of the installation is lower than the allowable range under the preset third settlement depth condition, preliminarily determines that the connection strength between the hydraulic prefabricated assembled components is lower than the allowable range, and performs a secondary determination on whether the connection strength between the hydraulic prefabricated assembled components is lower than the allowable range according to the inclination angle of the prefabricated components;

[0095] Set the preset first settlement depth to h1 and the preset second settlement depth to h2, then:

[0096] The preset first settlement depth condition is h≤h1;

[0097] The preset second settlement depth condition is h1<h≤h2;

[0098] The preset third settlement depth condition is h2<h.

[0099] It can be understood that the value of the preset first settlement depth h1 is set to the maximum value of the standard settlement range in this project, and the value of the preset second settlement depth h2 is set to about 1.5 times of h1, which can obtain a better judgment effect.

[0100] Three judgment conditions are set for the settlement depth in order to determine the causes of settlement that affect stability. According to different settlement depths, the different causes of settlement can be accurately determined and corrections can be made accordingly.

[0101] Specifically, the central control module determines three types of adjustment methods for the leveling height of the subsequent construction plane according to the difference between the settlement depth of the component and the preset first settlement depth under the preset second settlement depth condition, wherein:

[0102] The first type of adjustment method is that the central control module adjusts the leveling height of the subsequent construction plane to a preset leveling height under the preset first settlement depth difference condition;

[0103] The second type of adjustment method is that the central control module uses a preset first height adjustment coefficient α1 to adjust the leveling height of the subsequent construction plane to the first leveling height under the preset second settlement depth difference condition;

[0104] The third type of adjustment method is that the central control module uses a preset second height adjustment coefficient α2 to adjust the leveling height of the subsequent construction plane to the second leveling height under a preset third settlement depth difference condition;

[0105] Assuming that the difference between the settlement depth h of the component and the preset first settlement depth h1 is Δh, the preset first settlement depth difference is Δh1, and the preset second settlement depth difference is Δh2, then:

[0106] The preset first settlement depth difference condition is Δh≤Δh1;

[0107] The preset second settlement depth difference condition is Δh1<Δh≤Δh2;

[0108] The preset third settlement depth difference condition is Δh2≤Δh;

[0109] It can be understood that the value of the preset first settlement depth difference Δh1 is set to 0.3 times h2-h1, and the value of the preset second settlement depth Δh2 is set to about 0.7 times h2-h1, which can obtain a better judgment effect; the preset first height adjustment coefficient is less than the preset second height adjustment coefficient and is greater than 1, α2>α1>1; the preset leveling height can be based on the leveling height corresponding to the settlement depth set to Δh1 in a limited number of tests, and similarly, the first leveling height can be based on the leveling height corresponding to the settlement depth set to Δh2 in a limited number of tests, and the second leveling height can be based on the leveling height corresponding to the local maximum settlement depth in the historical record set in a limited number of tests.

[0110] Different adjustment methods are formulated for different causes of settlement, so that the adjustment results are more accurate and the corresponding adjustment process is faster.

[0111] Specifically, the angular displacement sensor measures the offset angle of the component connection at the third settlement depth, and the central control module determines whether the connection strength between adjacent prefabricated components is within the allowable range according to the offset angle.

[0112] The first type of connection strength angle determination method is that the central control module determines that the stability of the installation is within the allowable range under the first offset angle condition;

[0113] The second type of connection strength angle determination method is that the central control module determines that the installation stability is lower than the allowable range under the second offset angle condition;

[0114] Among them, the second offset angle condition is that the offset angle is less than or equal to the first offset angle; the second offset angle condition is that the offset angle is greater than the first offset angle.

[0115] It can be understood that the first offset angle is an angle that does not affect the horizontality during the subsequent construction process and can still be stabilized within the allowable range. It is set according to the relevant construction standards of this project.

[0116] Specifically, the central control module determines two types of adjustment methods for the leveling height of the subsequent construction plane according to the difference between the settlement depth of the component and the preset first settlement depth, wherein;

[0117] The first type of adjustment method is that the central control module adjusts the leveling height of the subsequent construction plane to the second leveling height under the preset third settlement depth difference condition;

[0118] The second type of adjustment method is that the central control module adjusts the bolt embedded holes under the preset third settlement depth difference condition to enhance the connection strength between the components and modify the offset angle;

[0119] Different adjustment methods are set for settlements caused by different connection strengths in order to reduce unnecessary adjustment steps. Only bolt embedded holes are adjusted for components that must be adjusted, making the adjustment process more efficient and accurate.

[0120] It is understandable that the preset leveling height can be adjusted by modifying the flatness of the ground surface or compacting the ground to achieve the leveling height, and no specific limitation is made here.

[0121] Specifically, in step S4, the central control module determines whether the vibration intensity during transportation is within the allowable range according to the total length of the prefabricated components, in two ways:

[0122] The first type of vibration intensity determination method is that the central control module determines that the stability of transportation is within an allowable range under the condition of a preset first total connection length;

[0123] The second type of vibration intensity determination method is that the central control module determines that the stability of transportation is lower than the allowable range under the condition of the preset second total connection length;

[0124] Assuming the total length of the prefabricated components to be L, and the first total length to be L1, we have:

[0125] The preset first connection total length condition is L≤L1;

[0126] The preset second connection total length condition is L1<L;

[0127] It can be understood that the first total connection length L1 is 0.7 times the longest distance of the straightness detection in this project, which is generally a number of prefabricated parts. As for the quantity value, it can be obtained according to the corresponding standards of the project and will not be repeated here.

[0128] The total length of the connection of the prefabricated components is determined during transportation in order to determine whether the vibration generated by the machine during transportation affects the connection stability of the prefabricated components, thereby avoiding insufficient stability of the connection caused by direct installation;

[0129] Specifically, two types of adjustment methods for the rotation speed of the power motor are determined according to the difference in the total length of the connection of the prefabricated components, wherein;

[0130] The first type of vibration intensity adjustment method is that the central control module continues to maintain normal transportation in the current transportation state under the first connection total length difference condition;

[0131] The second type of vibration intensity adjustment method is that the central control module adjusts the power motor speed to the first speed using a preset first speed under the second total connection length difference condition;

[0132] Assuming the difference between the total connection length L of the prefabricated component and the preset first total connection length L1 is ΔL1, then:

[0133] The preset first connection total length difference condition is L1≤ΔL1;

[0134] The preset second connection total length difference condition is ΔL1≤L1;

[0135] It can be understood that the value of the first difference is set to 0.3 times the longest distance of the straightness detection in this project.

[0136] The vibration intensity during transportation is adjusted by adjusting the speed of the power motor to achieve the effect of adjusting the stability during transportation. This is simpler and more effective than setting other adjustment methods.
