Description

Technical Field

[0001] The present invention relates to the technical field of building wall installation, and particularly relates to a construction method for a green energy-saving prefabricated building wall. Background Art

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to a factory. Building components and fittings (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory and transported to the building construction site, and then assembled and installed on-site through reliable connection methods. Building houses can be manufactured in batches and sets like machine production. As long as the prefabricated house components are transported to the construction site and assembled, the building is completed.

[0003] A Chinese patent with the publication number CN112459503B and the name of a construction method for installing a thermal insulation and energy-saving prefabricated building wall aims to solve the problem that "the installation of the current prefabricated building wall requires a hoisting machine to hoist each prefabricated building wall to the splicing and installation position respectively, and then the construction workers can hold the wall by hand to control the falling direction of the wall, and then clamp and fix it before carrying out the assembly and installation, and this process is cumbersome". This application places multiple walls through a feeding mechanism, then transports the walls to the main frame mechanism, and lifts the walls to the clamping mechanism through the main frame mechanism. Then, the clamping mechanism clamps the wall and transports it to the installation position. When the wall enters the main frame mechanism from the feeding mechanism, it is necessary to manually take out the single wall placed on the feeding mechanism first, and then place it on the lifting plate, and its degree of automation is relatively low. Therefore, this application proposes an installation construction device that can automatically transfer multiple stacked walls one by one to solve the above problems. Summary of the Invention

[0004] Based on the technical problem of the relatively low degree of automation in the prior art, the present invention proposes a construction method for a green energy-saving prefabricated building wall.

[0015] Preferably, the clamping mechanism includes an orientation control plate disposed in front of the shed frame and above the pallet. At the front end of the orientation control plate, there are a pair of L-shaped clamping plates distributed oppositely. At the middle position of the orientation control plate, there is a secondary shaft rotatably connected thereto. At the front end of the secondary shaft, a first connecting rod is fixedly sleeved. Both free ends of the first connecting rod are rotatably connected to a second connecting rod whose end is rotatably connected to the clamping plate. At the front end of the orientation control plate, there is an installation opening located between the two clamping plates.

[0020] Compared with the prior art, the present invention provides a construction method for a green energy-saving prefabricated building wall, having the following beneficial effects:

[0021] 1. For a construction method of a green energy-saving prefabricated building wall, place the prefabricated building walls neatly in the placement opening, and then start the first motor. The output shaft of the first motor drives the progressive push wheel to rotate. The progressive push wheel engages with the convex column, driving the pallet to move forward progressively. When the frontmost prefabricated building wall moves forward and contacts the guiding inclined surface, the clamping block is forced to move downward until the prefabricated building wall enters the clamping opening. The first spring pushes the slider and the whole clamping block to move upward and reset, that is, the prefabricated building wall is clamped through the clamping opening, and the single wall can be automatically separated from the feeding mechanism without manual transfer of the single wall.

[0022] 2. A construction method for a green energy-saving prefabricated building wall. Start the second motor. The output shaft of the second motor drives the main shaft and a set of first gears to rotate. The first gears engage to drive the first rack to move upward. Subsequently, the first rack synchronously drives the overall upward movement of the bracket and the support plate, lifting the clamped prefabricated building wall. The top of the prefabricated building wall contacts the arc structure of the support bar and squeezes the support bar into the installation opening. When the main shaft rotates, it synchronously drives the second gear to rotate. The second gear engages to drive the second rack to move downward. The second rack engages to drive the toothed bar and the auxiliary shaft to rotate counterclockwise. When the auxiliary shaft rotates, it synchronously drives the first connecting rod to rotate. Subsequently, the two second connecting rods respectively pull the two clamping plates inward until the clamping plates clamp the prefabricated building wall from both sides. At this time, the prefabricated building wall just moves above the support bar. The second spring pushes the support bar outwards to support the prefabricated building wall from the bottom. One side of the wall is attached to the direction control plate, and active clamping of the wall can be achieved during the lifting process.

[0023] 3. A construction method for a green energy-saving prefabricated building wall. Before starting the alignment mechanism, first start the second motor to rotate in the reverse direction, so that the clamping mechanism releases the clamping of the wall and drives the separation and positioning mechanism to move downward for reset. At this time, the wall is supported by the support bar on the direction control plate. Then start the first push rod. The output shaft of the first push rod pushes the bridge plate, the insertion post, the direction control plate and the wall towards the installation point, and then manual assembly can be carried out, thus realizing the fixed-point transportation of the wall.

[0048] Refer to Figures 2 - 15 , a construction method for a green energy-saving prefabricated building wall, which uses a building wall installation construction device. The construction device includes a feeding mechanism, a separation and positioning mechanism, a lifting mechanism, a clamping mechanism, an alignment mechanism, and a height adjustment mechanism. The feeding mechanism includes a shed 1, a T-shaped slide rail 2 fixed to the inner wall of the bottom of the shed 1, and a placement plate 3 slidably connected to the T-shaped slide rail 2. The upper part of the placement plate 3 is of a U-shaped structure, and the lower part is of a T-shaped structure. A plurality of uniformly distributed placement openings 4 for placing prefabricated building walls are opened at the top of the placement plate 3. A strip plate 19 is fixed to the side of the T-shaped structure of the placement plate 3, and a plurality of uniformly distributed convex columns 20 are fixed to the outside of the strip plate 19. A first motor 21 is fixed to the outside of the T-shaped slide rail 2, and the output shaft of the first motor 21 is connected to a progressive push wheel 22 that engages with the convex columns 20. Place the prefabricated building walls neatly in the placement openings 4, and then start the first motor 21. The output shaft of the first motor 21 drives the progressive push wheel 22 to rotate. The progressive push wheel 22 engages with the convex columns 20 to drive the pallet 5 to move forward progressively.

[0049] Further, the separation and positioning mechanism includes a pallet 5 disposed between the prefabricated building wall and the placement plate 3. A pair of oppositely distributed brackets 6 are fixedly connected to the front end of the pallet 5. A cushion block 18 that abuts against the inner wall of the bottom of the placement plate 3 is disposed at the bottom of the pallet 5. Two symmetrical openings 7 are opened at the top of the pallet 5. Sliding grooves 8 are opened on both inner walls of the openings 7. A slider 10 is slidably connected in the sliding grooves 8. A first spring 9 is fixed to the bottom end of the slider 10, and the other free end of the first spring 9 is fixed to the bottom of the sliding grooves 8. A clamping block 11 detachably connected to the slider 10 is disposed between the two sliders 10. A clamping opening 13 for clamping the prefabricated building wall is opened at the top of the clamping block 11. An introduction inclined surface 12 exposed above the opening 7 is provided on the rear end surface of the clamping block 11. When the frontmost prefabricated building wall moves forward, it contacts the introduction inclined surface 12, and the clamping block 11 moves downward under force until the prefabricated building wall enters the clamping opening 13. The first spring 9 pushes the slider 10 and the whole of the clamping block 11 to move upward and reset, that is, the prefabricated building wall is clamped through the clamping opening 13.

[0050] Furthermore, through holes 14 communicating with the sliding grooves 8 are formed on both sides of the pallet 5. A round hole 15 is formed on the clamping block 11. A screw rod 17 passing through the through hole 14 is inserted into both the round hole 15 and the slider 10 near the through hole 14. A threaded groove 16 threadedly connected to the screw rod 17 is formed on the inner side surface of the other slider 10.

[0051] Furthermore, the lifting mechanism includes a group of support columns 23 fixed to the top of the shed frame 1. The same frame 24 is fixed to the tops of the two support columns 23. A main shaft 25 is rotatably connected inside the frame 24. A group of first gears 26 are sleeved on the main shaft 25. A second motor 27 with its output shaft connected to the end of the main shaft 25 is fixed to one side of the frame 24. A first rack 28 slidably connected to the frame 24 and meshing with the first gears 26 is arranged on the front inner wall of the frame 24. The end of the first rack 28 is fixed to the support 6. By starting the second motor 27, the output shaft of the second motor 27 drives the main shaft 25 and the group of first gears 26 to rotate. The first gears 26 drive the first rack 28 to move upward by meshing, and then the first rack 28 synchronously drives the whole support 6 and the pallet 5 to move upward, so as to lift the clamped prefabricated building wall body.

[0052] Furthermore, the clamping mechanism includes an orientation control plate 31 arranged in front of the shed frame 1 and above the pallet 5. A pair of L-shaped clamping plates 32 distributed oppositely are arranged at the front end of the orientation control plate 31. A secondary shaft 33 rotatably connected to the orientation control plate 31 is arranged at the middle position of the orientation control plate 31. A connecting rod 34 is fixedly sleeved on the front end of the secondary shaft 33. Connecting rods 35 with their ends rotatably connected to the clamping plates 32 are rotatably connected to both free ends of the connecting rod 34. An installation opening located between the two clamping plates 32 is formed at the front end of the orientation control plate 31. A support bar 43 with an arc-shaped front end is inserted into the installation opening. Guide grooves 44 are formed on both sides of the support bar 43. Guide blocks 45 fixed to the side wall of the installation opening are slidably connected to the guide grooves 44. A second spring 46 with its other free end fixed to the front inner wall of the front end of the guide groove 44 is fixed to the front end of the guide block 45. When the prefabricated building wall body is lifted upward, the top of the prefabricated building wall body contacts the arc-shaped structure of the support bar 43 and presses the support bar 43 into the installation opening. When the secondary shaft 33 rotates, it synchronously drives the connecting rod 34 to rotate, and then the two connecting rods 35 respectively pull the two clamping plates 32 inward until the clamping plates 32 clamp the prefabricated building wall body from both sides. At this time, the prefabricated building wall body just moves above the support bar 43. The second spring 46 pushes the support bar 43 to move outwards to support the prefabricated building wall body from the bottom, and one side of the wall body is attached to the orientation control plate 31.

[0053] Furthermore, a T-shaped sliding seat is arranged at the rear end of the clamping plate 32. A pair of docking grooves forming a sliding fit with the sliding seat are formed at the front end of the orientation control plate 31, which can facilitate the assembly of the clamping plate 32 to the orientation control plate 31, so that the two form a sliding fit.

[0054] Further, a second gear 37 is fixedly sleeved on the main shaft 25, a second rack 38 which is slidably connected thereto is arranged on the inner wall of the rear end of the frame 24, a toothed bar 36 which meshes with the second rack 38 is fixedly sleeved on the auxiliary shaft 33. When the wall body of the prefabricated building is lifted, the main shaft 25 synchronously drives the second gear 37 to rotate, the second gear 37 meshes to drive the second rack 38 to move downward, and the second rack 38 meshes to drive the toothed bar 36 and the auxiliary shaft 33 to rotate counterclockwise.

[0055] Further, the alignment mechanism includes a pair of fixing plates 29 fixed to the top of the shed frame 1. Insertion columns 30 fixed to the control plate 31 are inserted into the fixing plates 29. The same bridge plate 40 is fixed to the rear ends of the two insertion columns 30. A first push rod 39 whose output shaft is fixed to the bridge plate 40 is fixed to the top of the shed frame 1. Before starting the alignment mechanism, first start the second motor 27 to rotate in the reverse direction, so that the clamping mechanism releases the clamping of the wall body and drives the separation and positioning mechanism to move downward to reset. At this time, the wall body is supported by the support bar 43 on the control plate 31. Then start the first push rod 39, and the output shaft of the first push rod 39 pushes the bridge plate 40, the insertion columns 30, the control plate 31 and the wall body to move towards the installation point, and then manual assembly can be carried out.

[0056] Further, the height adjustment mechanism is located on the bottom plate 42 below the shed frame 1. Four second push rods 41 whose output shafts are fixed to the shed frame 1 are fixed to the top of the bottom plate 42 at the four corners. By starting the second push rods 41, the output shafts of the second push rods 41 drive the whole shed frame 1 to move upward, so that the device can be adaptively adjusted according to the installation height of the wall body.

[0057] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
