Description

Technical Field

[0001] The present invention relates to a method for constructing prefabricated walls, and in particular to a method and structure for constructing a prefabricated wall calibration device applied in the field of prefabricated building construction technology. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. During the construction process of prefabricated buildings, vertical testing is usually required to ensure that the completed building meets the standards.

[0003] Invention patent 202210380453.6 discloses a wall panel verticality monitoring device for prefabricated building construction, including a chassis and a calibration component. The upper surface of the chassis has a groove, within which a rotating plate is fitted. An adjusting frame is fixedly connected above the rotating plate. A locking bolt is slidably connected within a sliding groove. A slide rail is provided on the inner surface of the adjusting frame. An adjusting ring is fixedly connected between the sliders. A fastening bolt is slidably connected within a guide groove. A guide rail is provided on the inner surface of the adjusting ring. A base plate is fixedly connected between the locking blocks. Indicator frames are fixedly connected to the front and right sides of the upper surface of the base plate. A symmetrical sliding groove is provided in the middle of the upper and lower surfaces of the base plate, within which the calibration component for detecting the verticality of the wall panel is located. Compared with existing verticality monitoring methods, this wall panel verticality monitoring device for prefabricated building construction improves monitoring accuracy and is easier to carry.

[0004] In existing technologies, there are many manual steps involved in the verticality testing of prefabricated walls. These manual operations are prone to errors, leading to incorrect test results, which can affect the normal construction of the prefabricated walls and, in severe cases, may even cause safety accidents. Summary of the Invention

[0005] The technical problem that this invention aims to solve in response to the above-mentioned prior art is that when performing verticality testing on assembled walls, there are many manual intervention steps by construction personnel. During the manual operation, operational errors are easily generated, leading to incorrect test results and affecting the normal construction of the assembled walls.

[0006] To solve the above problems, the present invention provides an assembly wall calibration device, including a fixed base, a leveling module placed on the upper end of the fixed base, an adjusting plate and a phase change material placed inside the leveling module, the density of the adjusting plate being less than the density of the phase change material, an electric guide rail fixedly connected to the upper end of the adjusting plate, an electric slider slidably connected on the electric guide rail, and a vertical laser instrument mounted on the electric slider.

[0007] Its usage mainly includes the following steps:

[0008] S1. Preparation: Select a test location in the prefabricated wall construction area. The test location should be 15-20 meters away from the prefabricated wall, and there should be no vegetation or debris obstructing the test location from the prefabricated wall. Clean and level the soil at the test location, and use multiple locking bolts to fix the base to the test location.

[0009] S2. Leveling: Place the leveling module on the upper side of the fixed base and fix it. Heat the phase change material to make it liquefy. At this time, under the action of gravity, the liquid surface of the phase change material is horizontal. The leveling plate floating on the surface of the phase change material will also automatically level itself. As the heating stops, the phase change material solidifies, and the leveling work ends.

[0010] S3. Calibration: Install the electric guide rail, electric slider, and vertical laser on the adjustment plate after step S2. Use the electric guide rail and electric slider to move the electric slider and vertical laser to a suitable height so that the detection light emitted by the vertical laser, which is perpendicular to the horizontal plane, falls on the middle of the side of the assembly wall. Adjust the position of the assembly wall according to the positional relationship between the detection light and the assembly wall until the side of the assembly wall coincides with the detection light. The calibration is then completed, and the assembly wall proceeds to the subsequent construction process.

[0011] The above-mentioned prefabricated wall construction method and structure reduce the intervention of construction personnel and increase the accuracy of calibration.

[0012] As a further improvement to this application, in step S1, the preparation work includes cleaning and leveling the soil at the detection location, compacting the soil to increase the structural strength of the soil in the detection area, thereby increasing the stability of the fixed base connected to it and reducing the impact on the calibration work.

[0013] As a further improvement of this application, the fixed base includes a base body. The upper end of the base body is chiseled with an installation groove that matches the shape of the leveling module. The leveling module is placed in the installation groove. An elastic pad is fixedly connected to the lower end of the base body. The chiseling of the installation groove can increase the stability of the connection between the fixed base and the leveling module and increase the calibration accuracy. The setting of the elastic pad can make the base body more adaptable to rough ground and make the elastic pad more stable.

[0014] As a further improvement of this application, the leveling module includes a housing with a leveling spherical groove carved at the upper end. The phase change material and the leveling plate are placed in the leveling spherical groove, and the leveling plate is in contact with the inner wall of the leveling spherical groove. An electric heating unit is fixedly connected to the bottom plate of the leveling spherical groove, and a limit ring is fixedly connected to the opening of the leveling spherical groove. The electric heating unit can heat and liquefy the phase change material to complete the leveling work.

[0015] As a further improvement to this application, the lower end of the leveling spherical groove is fixedly connected to multiple heat dissipation units, each of which includes heat dissipation fins. A temperature sensor is fixedly connected to one of the heat dissipation fins. The design of the heat dissipation fins can accelerate the dissipation of heat from the phase change material, allowing the phase change material to solidify quickly and significantly reducing the time required for step S2 and leveling. When the temperature sensor detects that the temperature is higher than the phase change temperature of the phase change material, it indicates that the phase change material has completely liquefied, and the electric heating unit immediately stops, reducing energy consumption.

[0016] As a further improvement to this application, multiple heat dissipation holes are drilled on the side wall of the housing. These holes are located on the upper side of the base body, which improves the airflow under the leveling module and further enhances the heat dissipation effect of the heat dissipation unit.

[0017] As another improvement of this application, the adjusting plate includes a plate body, the upper end of which is fixedly connected to a mounting flange, and the electric guide rail includes a fixing flange that matches the size of the mounting flange. The upper end of the fixing flange is fixedly connected to the guide rail body. Through the cooperation of the mounting flange and the fixing flange, the adjusting plate and the electric guide rail can be quickly connected and disassembled using bolts.

[0018] As another improvement of this application, multiple reinforcing units are placed in the phase change material. The density of the multiple reinforcing units is the same as that of the phase change material. The reinforcing unit includes a float. Multiple elastic fibers are fixedly connected to the outside of the float. Adjacent elastic fibers are entangled together. The elastic fibers are made of high-elasticity rubber. By adding reinforcing units to the phase change material, the multiple elastic fibers form a mesh structure to enhance the structural strength of the cured phase change material.

[0019] In summary, in this application, the prefabricated wall construction calibration work is only performed manually in step S1 and the preparation work. The selection of the detection location in step S1 is obtained by calculation, and the soil cleaning and leveling work at the detection location has little impact on the subsequent calibration work. In the subsequent leveling and calibration work, no human intervention is required, only the prefabricated wall needs to be adjusted, which reduces the operation intervention of construction personnel and increases the accuracy of calibration.

[0020] Meanwhile, reinforcing units are added to the phase change material, and multiple elastic fibers are used to form a mesh structure to enhance the structural strength of the cured phase change material. This makes the cured phase change material less susceptible to damage from the gravity of the adjusting plate and electric guide rail, and less likely to affect the leveling effect.

Detailed Implementation

[0033] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0034] First implementation method:

[0035] Figure 1-3 and Figure 8An assembly wall calibration device is shown, including a fixed base 1, a leveling module 3 placed on the upper end of the fixed base 1, an adjusting plate 4 and a phase change material placed inside the leveling module 3, the phase change material having a phase change temperature of switching from solid to liquid that is higher than the construction site temperature, the density of the adjusting plate 4 being less than the density of the phase change material, an electric guide rail 7 fixedly connected to the upper end of the adjusting plate 4, an electric slider 8 slidably connected to the electric guide rail 7, and a vertical laser instrument 9 mounted on the electric slider 8;

[0036] Its usage mainly includes the following steps:

[0037] S1. Preparation: Select a test location in the prefabricated wall construction area. The test location should be 20m away from the prefabricated wall, and there should be no vegetation or debris blocking the test location and the prefabricated wall. Clean and level the soil at the test location, and use multiple locking bolts 2 to fix the fixed base 1 at the test location.

[0038] S2. Leveling: Place the leveling module 3 on the upper side of the fixed base 1 and fix it. Heat the phase change material to make it liquefy. At this time, under the action of gravity, the liquid surface of the phase change material is horizontal. The leveling plate 4 floating on the surface of the phase change material will also automatically level. As the heating stops, the phase change material solidifies and the leveling work ends.

[0039] S3. Calibration: Install the electric guide rail 7, electric slider 8, and vertical laser 9 sequentially on the adjustment plate 4 after step S2. Use the electric guide rail 7 and electric slider 8 to move the electric slider 8 and vertical laser 9 to a suitable height so that the detection light emitted by the vertical laser 9, which is perpendicular to the horizontal plane, falls on the middle of the side of the assembly wall. Adjust the position of the assembly wall according to the positional relationship between the detection light and the assembly wall until the side of the assembly wall coincides with the detection light. The calibration is then completed, and the assembly wall proceeds to the subsequent construction process.

[0040] Compared to existing technologies, the prefabricated wall construction calibration work in this embodiment only requires manual operation in step S1 and the preparation work. The selection of the detection position in step S1 is obtained by calculation, and the soil cleaning and leveling work at the detection position has little impact on the subsequent calibration work. In the subsequent leveling and calibration work, no human intervention is required, only the prefabricated wall needs to be adjusted, reducing the operation intervention of construction personnel and increasing the accuracy of calibration.

[0041] The phase change material can be a composite material of paraffin and expanded graphite, with a phase change temperature of 48℃–52℃, which is higher than the normal construction temperature. During the verticality calibration process, it is easy to be in a solidified state.

[0042] Step S1: In the preparation work, after cleaning and leveling the soil at the test location, the soil to be tested is compacted to increase the structural strength of the soil in the test area, thereby increasing the stability of the fixed base 1 connected to it and reducing the impact on the calibration work.

[0043] Please see Figure 3-4 The fixed base 1 includes a base body 101. The upper end of the base body 101 is chiseled with an installation groove 102 that matches the shape of the leveling module 3. The leveling module 3 is placed in the installation groove 102. An elastic pad 103 is fixedly connected to the lower end of the base body 101. The chiseling of the installation groove 102 can increase the stability of the connection between the fixed base 1 and the leveling module 3 and increase the calibration accuracy. The setting of the elastic pad 103 can make the base body 101 more adaptable to rough ground and make the elastic pad 103 more stable.

[0044] Please see Figure 3 and Figures 5-6 The leveling module 3 includes a housing 301, with a leveling spherical groove 303 cut into its upper end. The phase change material and the leveling plate 4 are placed inside the leveling spherical groove 303, and the leveling plate 4 is fitted against the inner wall of the leveling spherical groove 303. An electric heating unit 5 is fixedly connected to the bottom plate of the leveling spherical groove 303, and a limit ring 304 is fixedly connected to the opening of the leveling spherical groove 303. The electric heating unit 5 can heat and liquefy the phase change material, thereby completing the leveling operation. Specifically, in this application, the method of placing the leveling plate 4 into the leveling spherical groove 303 can be achieved by designing the housing 301 with its upper and lower parts combined, or by designing the leveling plate 4 to be foldable and unfoldable for fixation. The lower end of the leveling spherical groove 303 is fixedly connected... There are multiple heat dissipation units 6, each including heat dissipation fins 601. A temperature sensor 602 is fixedly connected to one of the heat dissipation fins 601. The design of the heat dissipation fins 601 can accelerate the dissipation of heat from the phase change material, allowing the phase change material to solidify quickly and significantly reducing the time required for step S2 and leveling. When the temperature sensor 602 detects that the temperature is higher than the phase change temperature of the phase change material, it indicates that the phase change material is completely liquefied, and the electric heating unit 5 immediately stops, reducing energy consumption. Multiple heat dissipation holes 302 are drilled on the side wall of the outer shell 301. The multiple heat dissipation holes 302 are all located on the upper side of the base body 101, improving the airflow under the leveling module 3 and further increasing the heat dissipation effect of the heat dissipation unit 6.

[0045] Please see Figure 5 and Figure 7The adjusting plate 4 includes a plate body 401, and a mounting flange 402 is fixedly connected to the upper end of the plate body 401. The electric guide rail 7 includes a fixing flange 701 that matches the size of the mounting flange 402. The upper end of the fixing flange 701 is fixedly connected to the guide rail body 702. Through the cooperation of the mounting flange 402 and the fixing flange 701, the adjusting plate 4 and the electric guide rail 7 can be quickly connected and disassembled using bolts.

[0046] Second implementation method:

[0047] Figure 9-10 An assembly wall calibration device is shown, in which multiple reinforcing units 10 are placed in a phase change material. The density of the multiple reinforcing units 10 is the same as that of the phase change material. Each reinforcing unit 10 includes a float 1001. Multiple elastic fibers 1002 are fixedly connected to the outside of the float 1001. Adjacent elastic fibers 1002 are wound together. The elastic fibers 1002 are made of high elastic rubber.

[0048] In this embodiment, a reinforcing unit 10 is added to the phase change material, and multiple elastic fibers 1002 are used to form a mesh structure to strengthen the structural strength of the cured phase change material, so that the cured phase change material is not easily damaged by the gravity of the adjusting plate 4 and the electric guide rail 7, and is not easily affected by the leveling effect.

[0049] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
