Description

Technical Field

[0001] The present invention relates to an assembly wall construction method, and in particular to an assembly wall construction method and structure applied in the technical field of assembled building construction. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through 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] The specification of invention patent 202210380453.6 discloses a wall panel verticality monitoring device for prefabricated building construction, comprising a chassis and a calibration assembly. The chassis has an embedded groove on its upper surface, and a rotating plate is embedded in the embedded groove. An adjustment frame is fixedly connected above the rotating plate, and a locking bolt is slidably connected in the slide groove. A slide rail is provided on the inner surface of the adjustment frame, and an adjustment ring is fixedly connected between the sliders. A fastening bolt is slidably connected in the guide groove. A guide rail is provided on the inner surface of the adjustment ring. A base plate is fixedly connected between the blocks, and an indicator frame is fixedly connected to the front and right of the upper surface of the base plate. Shifting grooves are symmetrically provided in the middle of the upper and lower surfaces of the base plate. A calibration assembly for detecting the verticality of the wall panel is arranged in the shifting groove. Compared with existing verticality monitoring methods, this wall panel verticality monitoring device for prefabricated building construction improves monitoring accuracy and is easy to carry.

[0004] In the prior art, when performing verticality inspection on assembly walls, construction workers have to manually intervene in many steps. During the manual operation, construction workers are prone to operational errors, which lead to erroneous inspection results, affecting the normal construction of the assembly wall. In serious cases, it is easy to induce production safety accidents. Summary of the Invention

[0005] In view of the above-mentioned existing technology, the technical problem to be solved by the present invention is that when performing verticality detection on the assembly wall, there are many steps in which construction personnel manually intervene in the operation. During the manual operation of the construction personnel, operational errors are easily generated, resulting in errors in the detection results, which affects the normal construction of the assembly wall.

[0006] To solve the above problems, the present invention provides an assembly wall construction structure, comprising a fixed base, a leveling module placed on the upper end of the fixed base, a leveling plate and a phase change material placed in the leveling module, the density of the leveling plate being less than that of the phase change material, an electric guide rail fixedly connected to the upper end of the leveling plate, an electric slider slidably connected to 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 assembly wall construction area. The test location should be 15-20 meters away from the assembly wall, and there should be no vegetation or debris blocking the test location and the assembly wall. Clean and level the soil at the test location, and secure the fixed base to the test location using multiple locking bolts.

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

[0010] S3. Calibration work: Install the electric guide rail, electric slider and vertical laser instrument in sequence on the adjustment plate after step S2. Use the cooperation of the electric guide rail and the electric slider to move the electric slider and the vertical laser instrument to a suitable height, so that the detection light emitted by the vertical laser instrument that is perpendicular to the horizontal plane falls on the middle position of the side of the assembly wall, and 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 work is completed and the assembly wall enters the subsequent construction process.

[0011] In the above-mentioned assembly wall construction method and structure, the operation intervention of construction personnel is reduced and the accuracy of calibration is increased.

[0012] As a further improvement of the present application, in step S1, during the preparatory work, after completing the cleaning and leveling of the soil at the detection location, the detected soil is compacted to increase the structural strength of the soil in the detection area, thereby increasing the stability of the fixed base connected thereto and reducing the impact on the calibration work.

[0013] As a further improvement of the present application, the fixed base includes a base body, the upper end of the base body is provided with a mounting groove matching the shape of the leveling module, the leveling module is placed in the mounting groove, and the lower end of the base body is fixedly connected with an elastic pad, wherein the mounting groove can increase the stability of the connection between the fixed base and the leveling module and increase the calibration accuracy, while the provision of the elastic pad can make the base body more easily adapt to rough ground, making the elastic pad more stable.

[0014] As a further improvement of the present application, the leveling module includes an outer shell, a leveling spherical groove is opened at the upper end of the outer shell, 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 limiting ring is fixedly connected to the opening of the leveling spherical groove, wherein the electric heating unit can heat and liquefy the phase change material, thereby completing the leveling work.

[0015] As a further improvement and supplement to the present application, a plurality of heat dissipation units are fixedly connected to the lower end of the leveling spherical groove, and the plurality of heat dissipation units all include heat dissipation fins. A temperature sensor is fixedly connected to a heat dissipation fin. The design of the heat dissipation fins can accelerate the heat dissipation of the phase change material, so that the phase change material can be quickly solidified, greatly 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 is completely liquefied, and the electric heating unit stops immediately, reducing energy consumption.

[0016] As a further improvement and supplement to the present application, a plurality of heat dissipation holes are opened on the side wall of the shell, and the plurality of heat dissipation holes are all located on the upper side of the base body, thereby improving the fluidity of the air on the lower side of the leveling module and further increasing the heat dissipation effect of the heat dissipation unit.

[0017] As another improvement of the present application, the adjustment plate includes a plate body, the upper end of the plate body is fixedly connected to a mounting flange, the electric guide rail includes a fixed flange matching the size of the mounting flange, the upper end of the fixed flange is fixedly connected to the guide rail body, and through the cooperation of the mounting flange and the fixed flange, the adjustment plate and the electric guide rail can be quickly connected and disassembled using bolts.

[0018] As another improvement of the present application, multiple reinforcing units are placed in the phase change material, and the density of the multiple reinforcing units is the same as that of the phase change material. The reinforcing unit includes a float, and multiple elastic fibers are fixedly connected to the outside of the float. Adjacent elastic fibers are intertwined together, and the elastic fibers are made of high-elastic rubber. Reinforcing units are added to the phase change material, and a network structure is formed by using multiple elastic fibers to enhance the structural strength of the cured phase change material.

[0019] To sum up, in this application, the assembly wall construction calibration work is only manually operated in step S1 and the preparatory work, and the selection of the detection position in step S1 is obtained through 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 assembly wall needs to be adjusted, which reduces the operational intervention of construction personnel and increases the accuracy of calibration.

[0020] At the same time, a reinforcing unit is added to the phase change material, and a network structure is formed by multiple elastic fibers to strengthen the structural strength of the solidified phase change material, so that the solidified phase change material is not easily damaged by the gravity of the leveling plate and the electric guide rail, and is not easily affected by the leveling effect.

DETAILED DESCRIPTION

[0033] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0034] The first implementation method:

[0035] Figure 1-3 and Figure 8An assembly wall construction structure is shown, comprising a fixed base 1, a leveling module 3 being placed on the upper end of the fixed base 1, a leveling plate 4 and a phase change material being placed within the leveling module 3. The phase change material has a phase transition temperature, from solid to liquid, higher than the construction site temperature. The density of the leveling plate 4 is lower than that of the phase change material. An electric guide rail 7 is fixedly connected to the upper end of the leveling plate 4, an electric slider 8 being slidably connected to the electric guide rail 7, and a vertical laser instrument 9 is mounted on the electric slider 8.

[0036] Its usage mainly includes the following steps:

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

[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 liquefy it. At this time, under the action of gravity, the liquid surface of the phase change material is horizontal, and the leveling plate 4 floating on the surface of the phase change material will also automatically adjust to the level. When the heating work stops, the phase change material solidifies, and the leveling work is completed.

[0039] S3. Calibration work: Install the electric guide rail 7, electric slider 8 and vertical laser instrument 9 in sequence on the adjustment plate 4 after step S2. Use the cooperation of the electric guide rail 7 and the electric slider 8 to move the electric slider 8 and the vertical laser instrument 9 to a suitable height, so that the detection light perpendicular to the horizontal plane emitted by the vertical laser instrument 9 falls on the middle position of the side of the assembly wall, and 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 work is completed and the assembly wall enters the subsequent construction process.

[0040] Compared with the prior art, the assembly wall construction calibration work of this embodiment is manually operated only in step S1 and the preparatory work, and the selection of the detection position in step S1 is obtained by calculation, while 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 assembly wall needs to be adjusted, which reduces the operational intervention of construction personnel and increases the accuracy of calibration.

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

[0042] Step S1, during the preparation work, after completing the cleaning and leveling of the soil at the detection location, the soil to be detected is compacted to increase the structural strength of the soil in the detection area, thereby increasing the stability of the fixed base 1 connected thereto and reducing the impact on the calibration work.

[0043] See also Figure 3-4 The fixed base 1 includes a base body 101. The upper end of the base body 101 is provided with a mounting groove 102 that matches the shape of the leveling module 3. The leveling module 3 is placed in the mounting groove 102. The lower end of the base body 101 is fixedly connected with an elastic pad 103. The mounting 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 easily adapt to rough ground, making the elastic pad 103 more stable.

[0044] See also Figure 3 and Figure 5-Figure 6 The leveling module 3 includes a shell 301, and a leveling spherical groove 303 is cut out at the upper end of the shell 301. The phase change material and the leveling plate 4 are placed in the leveling spherical groove 303, and the leveling plate 4 is in contact with the inner wall of the leveling spherical groove 303. The bottom plate of the leveling spherical groove 303 is fixedly connected with an electric heating unit 5, and the opening of the leveling spherical groove 303 is fixedly connected with a limiting ring 304, wherein the electric heating unit 5 can heat and liquefy the phase change material to complete the leveling work. In particular, in the present application, the method of placing the leveling plate 4 into the leveling spherical groove 303 can be achieved by designing the shell 301 to merge the upper and lower parts, or designing the leveling plate 4 to be foldable and unfoldable, and the lower end of the leveling spherical groove 303 is fixedly connected There are multiple heat dissipation units 6, and each of the multiple heat dissipation units 6 includes a heat dissipation fin 601. A temperature sensor 602 is fixedly connected to a heat dissipation fin 601. The design of the heat dissipation fin 601 can accelerate the heat dissipation of the phase change material, so that the phase change material can be quickly solidified, greatly 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 means that the phase change material is completely liquefied, and the electric heating unit 5 stops immediately to reduce energy consumption. Multiple heat dissipation holes 302 are opened on the side wall of the shell 301, and the multiple heat dissipation holes 302 are all located on the upper side of the base body 101, which improves the fluidity of the air on the lower side of the leveling module 3 and further increases the heat dissipation effect of the heat dissipation unit 6.

[0045] See also Figure 5 and Figure 7The adjusting plate 4 includes a plate body 401, the upper end of the plate body 401 is fixedly connected to a mounting flange 402, the electric guide rail 7 includes a fixing flange 701 that matches the size of the mounting flange 402, and 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] The second implementation method:

[0047] Figure 9-10 An assembly wall construction structure is shown, in which multiple reinforcement units 10 are placed in a phase change material. The density of the multiple reinforcement units 10 is the same as that of the phase change material. The reinforcement unit 10 includes a float 1001, and multiple elastic fibers 1002 are fixedly connected to the outside of the float 1001. Adjacent elastic fibers 1002 are intertwined together, and 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 a plurality of elastic fibers 1002 are used to form a mesh structure to strengthen the structural strength of the solidified phase change material, so that the solidified phase change material is not easily damaged by the gravity pressure of the leveling plate 4 and the electric guide rail 7, and is not easily affected by the leveling effect.

[0049] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
