Description

Technical Field

[0001] The present invention relates to the technical field of assembled buildings, and in particular to an assembled building support device and an assembly method thereof. Background Art

[0002] Prefabricated buildings refer to buildings that are assembled and installed on site through a specific and reliable connection method, such as various types of composite floors. When installing the composite floors, it is necessary to place a support frame underneath them, and then place the composite floors horizontally on the support frame. The composite floors are placed in the air, and finally cement is poured and the support frame is removed.

[0003] When the support frames in the prior art are used for support, multiple support frames are often placed at the bottom of the floor slab. However, the ground at the construction site is uneven, which causes the support frames to be unstable and sway left and right, making it impossible to horizontally support the floor slab, affecting the stability of the building after pouring, and causing the floor slab to be unstable. Therefore, when encountering uneven ground in actual construction, pads are often placed between the feet of the support frames and the ground. The pads are usually made of local materials such as waste paper, wood, etc. However, when this method is used for raising the floor, firstly, the mechanical structure itself is unstable (not strong enough), and the pads are easily squeezed away, resulting in unstable support of the floor slab. Secondly, it is difficult to find suitable pads, which invisibly increases the difficulty of construction.

[0004] And because the ground is uneven and the height changes irregularly, it is impossible to ensure that the upper end surface height of the supporting device is equal after the supporting device is leveled. However, the construction requires that all floor slabs must be kept within a small error height difference range to ensure the safety of the construction and the future stable use of the building. Therefore, it is necessary to adjust the height of the supporting plate to ensure that the height difference of the floor slab is within a very small range. Summary of the invention

[0005] The purpose of the present invention is to provide an assembled building support device and an assembly method thereof, which solves the problem that the existing support device cannot adapt to the uneven ground for stable support and cannot adjust the height of the upper end surface of the support device to be flush.

[0015] Preferably, a connecting plate is fixedly provided at the upper end of the first hydraulic cylinder, the upper end of the connecting plate is fixedly connected to the bottom end of the bottom plate, and an anti-slip member is fixedly provided at the lower end of the first hydraulic cylinder.

[0016] Preferably, a controller is fixedly provided on the hydraulic oil tank, the controller is electrically connected to the hydraulic oil tank, and the controller is electrically connected to both the laser rangefinder and the laser scanner.

[0017] Preferably, a plurality of universal wheels are arranged at the bottom end of the base plate, and a plurality of connecting members are fixedly arranged between the support member and the base plate.

[0018] Preferably, the support plate is spherically hinged with a plurality of metal balls.

[0019] A method for assembling an assembled building comprises the following specific steps:

[0020] S1. Move the device to a suitable position with the aid of the universal wheel;

[0021] S2. Then use the laser scanner and laser rangefinder to cooperate, adjust the height of each of the first hydraulic cylinders through the controller to keep the floor level;

[0022] S3. The support plate on the first support device is then adjusted to a suitable height, and then the laser rangefinder, the controller and the hydraulic tank cooperate with each other to detect and adjust the height of the support plate on the subsequent support device;

[0023] S4. After placing the floor slab, the metal ball of the ball joint can facilitate the construction workers to adjust the position and angle of the floor slab. After use, the device can be removed.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. Through the coordinated use of a laser scanner and at least two laser rangefinders, the laser rangefinder emits laser pulses onto the prefabricated wall panels or adjacent support plates and protrusions, and then the laser scanner scans and calculates the emitted point cloud data, and then feeds back to the controller, so that the controller controls the oil output of the hydraulic oil tank and the oil output ratio of the first proportional valve, so that the corresponding multiple first hydraulic cylinders extend to different heights, thereby achieving the purpose of making the base plate level and stable.

[0026] 2. The universal wheels can make the device easy to move, thereby facilitating movement. The connecting parts can increase the stability of the connection between the support and the base plate. The connecting plates can increase the contact area between the first hydraulic cylinder and the base plate, thereby reducing the pressure of the first hydraulic cylinder on the bottom of the base plate.

[0027] 3. Through the laser rangefinder and the protrusion, it is possible to judge whether the laser pulses of the laser rangefinder are all irradiated on the protrusion to judge the height difference of the support plate and which side is higher and which side is lower, so as to feedback to the controller so that the controller controls the extension or contraction of the second hydraulic cylinder, so that multiple support plates are at the same height, which is convenient for making the placed floor slabs at the same height, thereby ensuring the safety and stability of the building, and can also be adaptively adjusted according to the different heights of the prefabricated wall panels of the assembled building by controlling the retraction and extension of the second hydraulic cylinder, thereby increasing the scope of application of the device.

[0028] 4. The metal balls can be used to easily adjust the position and angle of the floor slab after placement, reducing the workload and labor intensity of the workers.

[0029] 5. An anti-skid part is arranged at the lower end of the first hydraulic cylinder, which can not only prevent skidding when supporting the floor slab, but also protect the bottom of the first hydraulic cylinder to prevent wear. At the same time, when transporting the device, the lower end of the first hydraulic cylinder can be extended from the bottom plate to a certain length, so that the bottom surface of the anti-skid part and the lower side of the universal wheel are in contact with the transportation tool, thereby protecting the universal wheel during transportation and preventing the small contact area between the universal wheel and the transportation tool during transportation, causing the device to move on the transportation tool, resulting in collision of the device or damage of the universal wheel due to vibration on uneven roads during transportation, thereby increasing the stability performance during transportation.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1

[0043] At present, when supporting the floor slab of a prefabricated building, a single bracket is usually used to set it up, and then the legs on the bracket are contacted with the bottom surface of the house, and then support beams are placed on multiple brackets, and then the floor slab is placed on the support beams to support the floor slab. This method is not only time-consuming and labor-intensive, but also the unfinished bottom surface of the house may have some uneven locations. Therefore, when using the bracket for support, it is also easy to affect the stability of the floor slab when supporting it, and it cannot meet the requirements of stable support for the floor slab in actual use.

[0044] In order to solve the above technical problems, please refer to the attached drawings of the specification. Figures 1 to 4It can be obtained that the first embodiment of the present invention provides an assembled building support device, including a base plate 1, a support member 2 is fixedly provided on the base plate 1, a support plate 3 is provided above the support member 2, and also includes a leveling component 4 and a detection component 6. The leveling component 4 is located at the lower side of the base plate 1 and is used to adjust the horizontality of the base plate 1. The detection component 6 is used to detect the height of the support plate 3 and the horizontality of the base plate 1. The leveling component 4 also includes a plurality of first hydraulic cylinders 401 fixedly provided on the base plate 1. The leveling component 4 also includes a hydraulic oil tank 402 fixedly provided at the upper end of the support member 2. Each first hydraulic cylinder 401 is connected to the hydraulic oil tank 402 through a first hydraulic oil pipe 403. Each first hydraulic oil pipe 403 is provided with a first proportional valve 404. The detection component 6 includes a plurality of laser rangefinders 601 arranged at one end of the support plate 3. The plurality of laser rangefinders 601 are distributed in the longitudinal direction. The support plate 3 is provided with a The laser scanner 603, the laser rangefinder 601 and the laser scanner 603 are electrically connected, and the laser rangefinder 601 and the laser scanner 603 cooperate to detect the height of the support plate 3 and the horizontality of the base plate 1. A protrusion 602 made of the same material as the support plate 3 is fixedly provided at one end of the support plate 3 away from the laser rangefinder 601, and one end of the laser rangefinder 601 can be irradiated onto the corresponding protrusion 602. A connecting plate 405 is fixedly provided at the upper end of the first hydraulic cylinder 401, and the upper end of the connecting plate 405 is fixedly connected to the bottom end of the base plate 1. An anti-slip member 406 is fixedly provided at the lower end of the first hydraulic cylinder 401. A controller 7 is fixedly provided on the hydraulic oil tank 402, and the controller 7 is electrically connected to the hydraulic oil tank 402. The controller 7 is electrically connected to the laser rangefinder 601 and the laser scanner 603. A plurality of universal wheels 101 are provided at the bottom end of the base plate 1, and a plurality of connecting members 102 are fixedly provided between the support member 2 and the base plate 1.

[0045] During specific use, the support member 2 is pushed, and the support member 2 drives the universal wheel 101 to rotate through the base plate 1, and the device is pushed to the specified position. Since the ground in the building has not been trimmed, there is a problem of unevenness. Therefore, when the universal wheel 101 contacts the ground, one of the universal wheels 101 may not be able to contact the ground, resulting in the base plate 1 being unable to maintain a horizontal state. Therefore, the base plate 1 needs to be kept level in order to better support the floor.

[0046] At this time, the prefabricated floor panels have been installed and the verticality has been adjusted. Therefore, the laser rangefinder 601 is used to emit laser pulses to irradiate the adjacent prefabricated floor panels. Then, the laser scanner 603 collects the data of the points on the surface of the laser pulse and the verticality of the wall of the prefabricated wall panels, and processes them to obtain the length difference of the laser pulse line and the position of the points, thereby calculating the inclination between the base plate 1 and the prefabricated wall panels, and then the processed data is fed back to the controller 7. The controller 7 controls the hydraulic oil tank 402 to transport hydraulic oil to the first hydraulic cylinder 401 through the first hydraulic oil pipe 403. At the same time, the controller 7 controls the amount of hydraulic oil discharged by the first proportional valve 404, thereby controlling the multiple first hydraulic cylinders 401 to rise to different heights. During this process, the second proportional valve 503 is in a closed state.

[0047] When supplying oil to the first hydraulic cylinder 401 corresponding to the universal wheel 101 in a suspended state, the purpose of supplying a larger amount of oil is achieved by controlling the first proportional valve 404. For the first hydraulic cylinder 401 corresponding to the universal wheel 101 in the highest position, a smaller amount of oil is supplied to achieve a state where only the corresponding universal wheel 101 is supported, and the inclination of the base plate 1 is corrected, so that the base plate 1 can be horizontally supported for better support.

[0048] After the second support device is placed, it is adjusted accordingly. The laser rangefinder 601 of the second support device emits laser pulses to the protrusion 602 of the adjusted support plate 3, and then the laser scanner 603 scans the point data and calculates it. By using the angle difference between the laser pulse line and the protrusion 602 or the prefabricated wall panel, the end of the protrusion 602 on the irradiated support plate 3 is parallel to the vertical end face of the prefabricated wall panel. The inclination angle and direction of the base plate 1 are calculated and then fed back to the controller 7. Then, the controller 7 controls the hydraulic oil tank 402 on the support device to supply oil to the first hydraulic cylinder 401 through the first proportional valve 404 and the first hydraulic oil pipe 403 according to the feedback content, and controls the oil supply to each first hydraulic cylinder 401 through the first proportional valve 404, thereby controlling the first hydraulic cylinder 401 to extend to different heights, so that the base plate 1 can still remain level when placed on an uneven ground.

[0049] In addition, when transporting the support device, since the contact area between the universal wheel 101 and the transportation vehicle is small, it is very easy to slip during transportation, causing the support device to move and collide with the transportation vehicle, or when encountering poor road conditions, it is easy for the support device to shake or bump, causing the universal wheel 101 to be damaged and require maintenance, resulting in delays in the construction period.

[0050] Therefore, when the supporting device is on the transport vehicle, the controller 7 can control the hydraulic oil tank 402 to transport hydraulic oil to the first hydraulic cylinder 401 through the first proportional valve 404 and the first hydraulic oil pipe 403, so that the anti-slip part 406 at the lower end of the first hydraulic cylinder 401 and the lower end of the universal wheel 101 are in contact with the transport vehicle, which can play a certain supporting role while preventing damage to the universal wheel 101. At the same time, the anti-slip effect of the anti-slip part 406 can prevent the supporting device from sliding.

[0051] By setting the universal wheel 101, the device is easy to move, thereby playing a role in facilitating movement. At the same time, through the coordinated use of the laser rangefinder 601 and the laser scanner 603, multiple laser rangefinders 601 emit laser pulses to the prefabricated wall panel or the adjacent support plate 3 and the protrusion 602, and then the laser scanner 603 scans and calculates the emitted point data, and then feeds back to the controller 7, so that the controller 7 controls the oil output of the hydraulic oil tank 402 and the oil output ratio of the first proportional valve 404, so that the corresponding multiple first hydraulic cylinders 401 extend to different heights, so as to achieve the purpose of making the bottom plate 1 level and stable. By setting the connecting member 102, the stability of the connection between the support member 2 and the bottom plate 1 can be increased. At the same time, during transportation, the anti-slip member 406 on the first hydraulic cylinder 401 and the universal wheel 101 can be in contact with the transportation tool, while assisting the universal wheel 101 in supporting, it can prevent the damage of the universal wheel 101 and play an effect of preventing the support device from sliding.

[0052] Embodiment 2

[0053] When the inventor put the above-mentioned embodiments into actual use, it was found that although the above-mentioned embodiment 1 can ensure the levelness of the base plate 1, due to the unevenness of the ground itself, when ensuring the levelness of the base plate 1, it is impossible to ensure that the height of the support plate 3 is equal. However, the construction requires that all floor slabs must be kept within a small error height difference range to ensure the safety of the construction and the future stable use of the building. Therefore, the height of the support plate 3 needs to be adjusted to ensure that the height difference of the floor slabs is within a very small range.

[0054] In order to solve the above technical problems, based on the above embodiment 1, please refer to the accompanying drawings of the specification. Figure 1 Fig. 9It can be obtained that the adopted technical solution includes a base plate 1, a support member 2 is fixedly provided on the base plate 1, a support plate 3 is provided above the support member 2, and also includes a height adjustment component 5 and a detection component 6. The height adjustment component 5 is arranged between the support member 2 and the support plate 3 and is used to adjust the height of the support plate 3. The detection component 6 is used to detect the height of the support plate 3. The height adjustment component 5 includes a plurality of second hydraulic cylinders 501 fixedly arranged on the upper end of the support member 2, each of the second hydraulic cylinders 501 is connected to the hydraulic oil tank 402 through a second hydraulic oil pipe 502, each of the second hydraulic oil pipes 502 is provided with a second proportional valve 503, and the plurality of second hydraulic cylinders 501 are provided with a plurality of second hydraulic cylinders 501. The ends are fixedly connected to the support plate 3. The detection component 6 includes a plurality of laser rangefinders 601 fixedly arranged at one end of the support plate 3. The laser rangefinder 601 is used to detect the height of the support plate 3 and the horizontality of the base plate 1. A protrusion 602 made of the same material as the support plate 3 is fixedly arranged at one end of the support plate 3 away from the laser rangefinder 601. One end of the laser rangefinder 601 can irradiate the corresponding protrusion 602. A controller 7 is fixedly arranged on the hydraulic oil tank 402. The controller 7 is electrically connected to the hydraulic oil tank 402. The controller 7 is electrically connected to the laser rangefinder 601. A plurality of metal balls 301 are provided on the ball joint of the support plate 3.

[0055] In actual use, based on the above-mentioned embodiment 1, after the base plate 1 is leveled, the height of the support plate 3 needs to be adjusted. Although the ground is uneven, the height difference is small, and the thickness of the support plate 3 is set to be greater than the height difference between the highest and lowest points of the ground. Therefore, when the laser rangefinder 601 is working, at least one laser pulse of the laser rangefinder 601 can be irradiated on the protrusion 602 of the adjacent support device.

[0056] When adjusting the height of the support plate 3, the height of the support device installed subsequently is adjusted based on the height of the protrusion 602 on the first support device placed in the first embodiment and the height of the support plate 3. First, the laser rangefinder 601 on the subsequent support device generates a laser pulse to the protrusion 602 of the adjusted support device, and then calculates the return time of the laser pulse to calculate whether the receiving time of the two laser rangefinders 601 is the same. When the receiving time is the same, as shown in the figure of the specification Figure 5 As shown, the heights of the two support plates 3 are the same, and there is no need to adjust the heights of the support plates 3 .

[0057] When the receiving time is different, there are several situations, as shown in the attached figure of the specification. Figures 6 to 9 As shown, it should be noted that the bottom plate 1 is in a horizontal state at this time. Figure 6As shown, the receiving result of the laser rangefinder 601 is fed back to the controller 7, which laser rangefinders 601 can irradiate the protrusion 602 and which are located above the irradiated support plate 3, so that the controller 7 controls the hydraulic oil tank 402 to extract the hydraulic oil in the second hydraulic cylinder 501 through the second hydraulic oil pipe 502 and the second proportional valve 503, thereby controlling the second hydraulic cylinder 501 to move downward. When the time for multiple laser rangefinders 601 to receive the laser pulses they emit is exactly the same, the extraction of the hydraulic oil in the second hydraulic cylinder 501 is stopped.

[0058] Situation Figure 7 As shown, the controller 7 also extracts the hydraulic oil in the second hydraulic cylinder 501 to lower the height of the second hydraulic cylinder 501. The second proportional valve 503 is capable of controlling the ratio of oil inlet and outlet. When the laser pulse emitted by the laser rangefinder 601 is tilted, the scanning result of the laser scanner 603 is fed back to the controller 7, so that the controller 7 controls a single or multiple second proportional valves 503 to change the oil outlet or oil suction rate of the second proportional valve 503, and adjusts the second hydraulic cylinder 501 separately, thereby avoiding uneven oil outlet and still ensuring that the support plate 3 is always in a horizontal state.

[0059] When the situation is as shown in the attached figure of the specification Figure 8 and Fig. 9 As shown, it is only necessary to feed back the result of the laser pulse receiving time of the laser rangefinder 601 to the controller 7. In this state, the laser rangefinder 601 on the lower side receives the laser pulse for a long time, and then the controller 7 controls the hydraulic oil tank 402 to transport hydraulic oil to the second hydraulic cylinder 501 through the second hydraulic oil pipe 502 and the second proportional valve 503, so that the second hydraulic cylinder 501 rises to a certain height, until the laser pulses of the two laser rangefinders 601 can just completely irradiate the protrusion 602, the controller 7 controls the hydraulic oil tank 402 to stop supplying oil, and closes the second proportional valve 503, so that the multiple support plates 3 are at the same height.

[0060] When the heights of all support plates 3 are adjusted to a flush state, the floor slab is placed on the support plate 3. Since the floor slab is lifted using a lifting device and then the floor slab is manually pulled and the direction and the falling point are adjusted, there will be a certain deviation in the placement position of the floor slab. At this time, it is necessary to manually use a crowbar to move the position of the floor slab. This process is time-consuming and labor-intensive, and is prone to safety accidents. Therefore, a metal ball 301 is provided on the support plate 3 on a ball hinge, and a small part of the metal ball 301 leaks out on the support plate 3. On this basis, when the floor slab is moved, the metal ball 301 can rotate slightly, thereby reducing the friction between the floor slab and the metal ball 301, which can greatly reduce the amount of manual labor, reduce the probability of safety accidents, and facilitate the adjustment of the angle and position of the floor slab.

[0061] By setting up the laser rangefinder 601 and the protrusion 602, it is possible to judge whether the laser pulses of the laser rangefinder 601 are all irradiated on the protrusion 602 to judge the height difference of the support plate 3 and which side is higher and which side is lower, so as to give feedback to the controller 7 so that the controller 7 controls the extension or contraction of the second hydraulic cylinder 501, so that multiple support plates 3 are at the same height, which is convenient for placing the floor slabs at the same height, thereby ensuring the safety and stability of the building, and the metal ball 301 is provided, which can facilitate the adjustment of the position and angle of the placed floor slab, reducing the workload and labor intensity of the workers.

[0062] Embodiment 3

[0063] On the basis of the above embodiment, this embodiment further provides a method for assembling a prefabricated building, including the following specific steps:

[0064] S1. Push the support member 2, the support member 2 moves the device to a suitable position through the base plate 1 with the help of the universal wheel 101;

[0065] S2. Then use the laser scanner 603 and the laser rangefinder 601 to cooperate, and feed the results back to the controller 7, and the controller 7 controls the hydraulic oil tank 402 and the first proportional valve 404 to adjust the height of the plurality of first hydraulic cylinders 401, respectively, so that the bottom plate 1 remains level;

[0066] S3. Then adjust the support plate 3 on the first support device to a suitable height, and then use the laser rangefinder 601 and the controller 7 and the hydraulic tank 402 to cooperate with each other to detect and adjust the height of the support plate 3 on the subsequent support device to be the same as the height of the first support plate 3;

[0067] S4. After placing the floor, the metal ball 301 of the ball joint can reduce the friction between the metal ball 301 and the floor, so that the metal ball 301 can rotate to a certain extent, so that the construction workers can adjust the position and angle of the floor conveniently. After use, the device can be removed.

[0068] In summary, the present invention provides an assembled building support device and an assembly method thereof, which can solve the technical problems of unstable support when the ground is uneven and inconvenient adjustment of multiple floor slabs to the same height.

[0069] The universal wheel 101, the first hydraulic cylinder 401, the hydraulic oil tank 402, the first proportional valve 404, the second hydraulic cylinder 501, the second proportional valve 503, the laser rangefinder 601, the laser scanner 603 and the controller 7 and their connection methods in the present invention are all prior arts and will not be described in detail here.

[0070] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
