Description

Technical Field

[0001] The present application relates to the technical field of building wall construction, and in particular to a wall reverse construction method and construction device. Background Art

[0002] Most of the factory buildings are steel structures. After the frame structure is completed, the walls need to be installed. The wall materials are usually blocks. Since the height of most factory buildings is above 5 meters, scaffolding needs to be built when installing the blocks to facilitate the construction workers to carry out the wall masonry work.

[0003] When building walls of different heights, the height of the scaffolding needs to be increased or decreased in a timely manner. Moreover, it is inconvenient to transport the blocks to the scaffolding for the construction workers to carry out the wall construction. Summary of the Invention

[0004] In order to facilitate construction workers to carry out masonry work on walls at high places, a wall reverse construction method and a construction device are provided.

[0005] In a first aspect, the present application provides a wall reverse construction device, which adopts the following technical solution:

[0006] A wall reverse construction device, comprising

[0007] A base, wherein a plurality of movable wheels are provided on the base;

[0008] A construction platform, which is escalable and arranged on a base;

[0009] A conduit is vertically arranged on the base, and one end of the conduit can be extended to abut against the floor;

[0010] A lifting arm is slidably arranged on the guide tube and is used for conveying the building blocks.

[0011] By adopting the above technical solution, the base is moved to the wall to be constructed by the moving wheels, the building blocks are placed on the lifting arm, and the construction workers stand on the construction platform and control the construction platform to rise to the height to be constructed. At the same time, the lifting arm is controlled to drive the building blocks to rise to the height to be constructed, thereby making it convenient for the construction workers to use the building blocks to carry out wall construction work at high places.

[0012] Preferably, a lifting mechanism is provided under the construction platform, and the lifting mechanism includes a first lifting tube fixed on the base, a second lifting tube is slidingly provided on the side wall of the first tube, a third lifting tube is slidingly provided on the side wall of the second lifting tube, the construction platform is fixed on the third lifting tube, and a driving component for driving the second lifting tube and the third lifting tube to lift and lower is provided on the base.

[0013] By adopting the above technical solution, the driving assembly can drive the second lifting tube to rise and fall on the side wall of the first lifting tube, and drive the third lifting tube to rise and fall on the side wall of the second lifting tube, thereby facilitating the height adjustment of the construction platform and facilitating construction workers to carry out masonry work on walls of different heights.

[0014] Preferably, a first through-groove is provided on the side wall of the first lifting tube, and a first sliding groove is provided on the side wall of the second lifting tube close to the first lifting tube, and the side wall of the first through-groove is slidably disposed in the first sliding groove;

[0015] A second through slot is formed on the side wall of the second lifting tube close to the third lifting tube, a second sliding slot is formed on the side wall of the third lifting tube close to the second lifting tube, and the side wall of the second through slot is slidably disposed in the second sliding slot.

[0016] By adopting the above technical solution, the second lifting tube is clamped with the first lifting tube through the first sliding groove, and the third lifting tube is clamped with the second lifting tube through the second sliding groove, thereby limiting the second lifting tube and the third lifting tube, so that the movement direction of the second lifting tube and the third lifting tube is both vertical.

[0017] Preferably, the driving assembly includes a winch and a first traction rope wound around the winch, a first pulley is provided on the first lifting tube, a first fixed end is provided below the first pulley, a second pulley is rotatably provided on the second lifting tube, a second fixed end is provided below the second pulley, a third fixed end is provided on the third lifting tube, the first traction rope is wound around the first pulley and fixed to the second fixed end, a second traction rope is wound around the second pulley, one end of the second traction rope is fixed to the first fixed end, and the other end of the second traction rope is fixed to the third fixed end.

[0018] With this technical solution, when the winch rotates, it winds the first traction rope, thereby pulling the second lifting tube up along the side wall of the first lifting tube. As the second lifting tube rises, because the first lifting tube is fixed to the base, the second traction rope provides traction to the third lifting tube, causing the third lifting tube to slide along the side wall of the second lifting tube, thereby raising the construction platform. Construction workers on the construction platform use the lifting mechanism to install walls of different heights.

[0019] Preferably, the catheter comprises a first telescopic tube and a second telescopic tube slidably disposed in the first telescopic rod tube, and the first telescopic tube is provided with a locking member for fixing the second telescopic tube.

[0020] By adopting the above technical solution, when the base is moved to the front of the wall to be constructed by the moving wheels, the second telescopic tube is extended until it abuts against the ceiling, and the first telescopic tube and the second telescopic tube are fixed with a locking member, thereby limiting the sliding of the second telescopic tube in the first telescopic tube. When the second telescopic tube abuts against the ceiling, it can squeeze the base, thereby limiting the base and reducing the possibility of movement of the base during construction.

[0021] Preferably, the locking member is a locking bolt, which is threadedly connected to the first telescopic tube and abuts against the second telescopic tube.

[0022] By adopting the above technical solution, the locking bolt is screwed until the end of the locking bolt passes through the first telescopic tube and abuts against the side wall of the second telescopic tube, thereby limiting the second telescopic tube and reducing the phenomenon of the second telescopic tube slipping inside the first telescopic tube.

[0023] Preferably, a sliding block is fixedly connected to the end of the lifting arm, a sliding groove for the sliding block to slide is provided in the second telescopic tube, a limiting block is fixedly connected to the lifting arm, and a limiting groove for the limiting block to slide is provided on the first telescopic tube.

[0024] By adopting the above technical solution, when the lifting arm is raised and lowered in the first telescopic tube, the limit groove limits the limit block, making it difficult for the lifting arm to swing; when the lifting arm is raised and lowered in the second telescopic tube, the sliding groove limits the sliding block, making it difficult for the lifting arm to swing, thereby reducing the possibility of blocks on the lifting arm falling off.

[0025] Preferably, a lifting assembly is provided on the second telescopic tube, and the lifting assembly includes a pulling rope fixedly connected to the lifting arm. A reel for releasing and reeling in the pulling rope is rotatably provided in the second telescopic tube.

[0026] By adopting the above technical solution, the reel is rotated to reel in and unreel the lifting rope, thereby completing the lifting and lowering functions of the lifting arm.

[0027] In a second aspect, the present application provides a method for constructing a steel structure spatial tube truss, comprising the following steps:

[0028] S1. Positioning and setting out: Positioning and setting out between concrete support columns based on the spacing between adjacent concrete support columns. This will first determine the position of the structural columns. The height of the girders will then be calculated by measuring the height of the concrete columns and marked on the concrete columns.

[0029] A construction column is vertically arranged according to the position of the cable, one end of the construction column is fixed with the cross beam, and the other end of the construction column is fixed with the ground. The side of the concrete support column facing the construction column is provided with a clamping column with the same size as the construction column;

[0030] S2. Install the block: the two sides of the block are provided with clamping grooves, the lifting arm is arranged between the construction column and the clamping column, the clamping grooves on the two sides of the block are respectively clamped with the clamping column and the construction column, the lifting arm lifts the block, and the top end of the block abuts against the cross beam until the top end of the block abuts against the cross beam;

[0031] S3. Fix the block: the block is provided with a fixing member for supporting the block between the construction column and the clamping column, and the gap at the connection of the block is filled by spraying a filling agent after the block is fixed;

[0032] S4. Install the waist beam: when the block is installed close to the waist beam, one end of the waist beam is vertically welded on the side wall of the construction column, the other end of the waist beam is welded on the side wall of the clamping column, and then the block below the waist beam is installed and constructed.

[0033] By adopting the above technical scheme, the positioning column replaces the construction column, thereby increasing the integrity and stability of the building, and the positioning column can limit the installation of the block and improve the neatness of the block during the installation process. By combining the wall reverse construction device to install the block from top to bottom, on the one hand, the block installation is more neat, and the combination of the positioning column, the waist beam and the steel column is more close, and on the other hand, the construction time of the wall is saved.

[0034] As a preferred, the block adjacent to the waist beam is provided with a fixing groove for clamping with the waist beam, thereby making the block more closely connected with the waist beam.

[0035] In summary, the present application has at least one of the following beneficial technical effects:

[0036] 1. The base is moved to the wall to be constructed by the moving wheel, the block is placed on the lifting arm, the construction personnel stand on the construction platform, the construction platform is controlled to rise to the height to be constructed, and the lifting arm is controlled to drive the block to rise to the height to be constructed, thereby facilitating the construction personnel to use the block to perform the wall construction work at a high place;

[0037] 2. When the winch rotates, the first traction rope is wound, thereby pulling the second lifting pipe to rise on the side wall of the first lifting pipe, when the second lifting pipe rises, the second traction rope provides a traction force to the third lifting pipe, thereby driving the third lifting pipe to slide on the side wall of the second lifting pipe, and further driving the construction platform to rise. The construction personnel on the construction platform and through the lifting mechanism install and construct the wall at different heights;

[0038] 3. Positioning columns can replace structural columns, thereby increasing the integrity and stability of the building. Positioning columns can also limit the installation of blocks, improving the neatness of the blocks during installation. By combining the wall reverse construction device to install blocks from top to bottom, on the one hand, it can not only ensure the neatness of the block installation and a tighter connection with the positioning columns, waist beams and steel columns, but also save wall construction time.

[0046] The following is combined with Figure 1-4 This application is described in further detail.

[0047] The embodiment of the present application discloses a wall reverse construction device. Figure 1 , including a base 1, a plurality of moving wheels 11 are provided under the base 1, and four moving wheels 11 are provided and are respectively arranged at four corners close to the base 1. A construction platform 3 is provided on the base 1, and a protective fence and a protective door for entering and exiting the construction platform 3 are provided around the construction platform 3.

[0048] Reference Figure 1 and Figure 2 A lifting mechanism 2 is provided on the base 1, and the lifting mechanism 2 includes a first lifting tube 21, a second lifting tube 22 and a third lifting tube 23. The first lifting tube 21 is fixed on the base 1, the second lifting tube 22 is slidably set on the side wall of the first lifting tube 21, the third lifting tube 23 is slidably set on the side wall of the second lifting tube 22, and the construction platform 3 is fixed on the top of the third lifting tube 23.

[0049] Reference Figure 2 A first sliding groove 221 is provided on the side wall of the second lifting tube 22 close to the first lifting tube 21, and a first through groove 211 is opened on the side wall of the first lifting tube 21. The side wall of the first through groove 211 is slidably set in the first sliding groove 221, so that the first lifting tube 21 limits the second lifting tube 22, so that the movement direction of the second lifting tube 22 is vertical.

[0050] Reference Figure 2 A second through-slot 222 is formed on the side wall of the second lifting tube 22 near the third lifting tube 23. A second sliding slot 231 is formed on the side wall of the third lifting tube 23 near the second lifting tube 22. The side wall of the second through-slot 222 slides within the second sliding slot 231. Thus, the second lifting tube 22 limits the third lifting tube 23, ensuring that the third lifting tube 23 moves vertically.

[0051] Reference Figure 2 A first pulley 212 is fixed to the top of the first lifting tube 21, a first fixed end 213 is fixed to the bottom end of the first lifting tube 21, a second pulley 223 is fixed to the top of the second lifting tube 22, a second fixed end 224 is fixed to the bottom end of the second lifting tube 22, and a third fixed end 232 is fixed to the bottom end of the third lifting tube 23.

[0052] Reference Figure 1 and Figure 2The lifting mechanism 2 further comprises a driving assembly for driving the second lifting pipe 22 and the third lifting pipe 23 to perform lifting movement, the driving assembly comprising a winch 24 and a first traction rope 25 wound on the winch 24, the first traction rope 25 being wound on a first pulley 212 at an end away from the winch 24 and fixed on a second fixed end 224. A second traction rope 26 is wound on a second pulley 223, one end of the second traction rope 26 being fixed on the first fixed end 213 and the other end of the second traction rope 26 being fixed on a third fixed end 232.

[0053] When the winch 24 rotates, the first traction rope 25 is wound, thereby pulling the second lifting pipe 22 to ascend on the side wall of the first lifting pipe 21. When the second lifting pipe 22 ascends, the second traction rope 26 provides traction force to the third lifting pipe 23, thereby driving the third lifting pipe 23 to slide on the side wall of the second lifting pipe 22, and further driving the construction platform 3 to ascend. During the construction of the factory building, the construction personnel on the construction platform 3 can install and construct the wall at different heights by means of the lifting mechanism 2.

[0054] With reference to Figure 1 The side wall of the base 1 is connected with a plurality of support arms 12, the number of the support arms 12 being four, and an end of each support arm 12 away from the base 1 is fixedly connected with a hydraulic telescopic rod 13. The hydraulic telescopic rod 13 can increase the height of the base 1, provide support force to the base 1, and reduce the pressure of the base 1 on the moving wheels 11 during the construction, thereby prolonging the service life of the moving wheels 11.

[0055] With reference to Figure 1 and Figure 3 Two guide pipes 4 are vertically and fixedly connected on the base 1, each guide pipe 4 comprising a first telescopic pipe 41 and a second telescopic pipe 42 slidably connected in the first telescopic pipe 41, and the end of the first telescopic pipe 41 being provided with a plurality of locking members 43, the locking members 43 being locking bolts, the locking bolts being threadedly connected with the first telescopic pipe 41 and abutting against the second telescopic pipe 42, and the ends of the two second telescopic pipes 42 being connected with an abutting plate 44.

[0056] With reference to Figure 3 The guide pipe 4 is slidably connected with a lifting arm 5, the first telescopic pipe 41 being provided with a receiving groove 411 in the length direction, the second telescopic pipe 42 being slidably arranged in the receiving groove 411, the second telescopic pipe 42 being provided with a sliding groove 421 in the length direction, and one end of the lifting arm 5 being fixedly connected with a sliding block 51 slidably arranged in the sliding groove 421. The two side walls of the lifting arm 5 are respectively fixedly connected with limiting blocks 52, and the receiving groove 411 is provided with limiting grooves 412 for the movement of the limiting blocks 52 on the two side walls.

[0057] With reference to Figure 3A lifting assembly 6 is provided at the end of the lifting arm 5 away from the base 1. The lifting assembly 6 includes a servo motor 63. The servo motor 63 is fixed to the side wall of the second telescopic tube 42. The driving end of the servo motor 63 passes through the side wall of the second telescopic tube 42 and is fixed with a winding drum 61. A pulling rope 62 is wound around the winding drum 61. The end of the pulling rope 62 away from the winding drum 61 is fixed to the sliding block 51.

[0058] The working principle of the reverse wall construction device of the present embodiment is as follows: the base 1 is moved to the front of the wall to be constructed, the hydraulic telescopic rod 13 is extended to raise the base 1 until the moving wheel 11 is suspended in the air, and then the second telescopic tube 42 is slid so that the abutment plate 44 is pressed against the ceiling in the room, and the locking bolt is tightened so that the locking bolt is pressed against the second telescopic tube 42, thereby limiting the position of the second telescopic tube 42. When the abutment plate 44 is pressed against the ceiling, the device can be limited in position, reducing the possibility of the device sliding during the construction process, thereby improving construction safety.

[0059] The hoist 24 rotates, reeling in the first traction rope 25, thereby pulling the second lifting tube 22 upward along the side wall of the first lifting tube 21. As the second lifting tube 22 rises, because the first lifting tube 21 is fixed to the base 1, the second traction rope 26 provides traction to the third lifting tube 23, causing the third lifting tube 23 to slide along the side wall of the second lifting tube 22, thereby raising the construction platform 3. During the construction of the factory building, due to its high floors, construction workers on the construction platform 3 and using the lifting mechanism 2 performed installation work on walls of different heights.

[0060] When construction workers are laying bricks on a higher wall, they need to first move the bricks 75 onto the scaffolding. However, when the scaffolding is high, it is not easy to move the bricks 75. Instead, the bricks 75 are placed on the lifting arm 5, and the servo motor 63 rotates to drive the winding drum 61 to reel in the bricks, thereby pulling the lifting arm 5 to move on the guide tube 4 until the lifting arm 5 is raised to the height of the construction platform 3, making it easier for construction workers to lay bricks on the construction platform 3.

[0061] The present application also discloses a wall reverse construction method, comprising the following steps:

[0062] S1. Positioning and setting out: refer to Figure 4Since the clearance height of the factory building is relatively high, generally greater than 5 meters, and the length of the wall is greater than 8 meters, according to the requirements of the building code, it is necessary to set a waist beam 73 and a structural column 72 on the wall to increase the integrity and stability of the building. According to the spacing between adjacent concrete support columns 71, positioning and laying out are performed between the concrete support columns 71 to first determine the position of the structural column 72. Then, by measuring the height of the concrete support column 71, the setting height of the waist beam 73 is calculated and marked on the concrete support column 71. In this embodiment, the structural column 72 and the waist beam 73 are both square steel. In the construction process of traditional buildings, the waist beam 73 and the structural column 72 are both reinforced concrete structures. First, it is necessary to plant steel bars in the wall, then install the formwork and pour concrete. After pouring, it is necessary to wait until the concrete reaches the initial setting strength before removing the formwork. The construction process of the structural column 72 and waist beam 73 made of concrete requires a lot of time and the construction steps are cumbersome. Using square steel to replace the concrete structural column 72 and waist beam 73 can save a lot of time, thereby improving the construction progress.

[0063] A structural column 72 is vertically installed according to the layout position. One end of the structural column 72 is fixed to the crossbeam 77, and the other end is fixed to the ground. A clamping column 74 is provided on the side of the concrete support column 71 facing the structural column 72. The clamping column 74 has the same size as the structural column 72 and is made of square steel.

[0064] S2. Install block 75: refer to Figure 5 In this embodiment, the blocks 75 are ALC autoclaved blocks 75; in other embodiments, they may be aerated blocks. Attachment slots 751 are provided on both sides of the blocks 75. The base 1 is moved in front of the wall to be constructed, with the lifting arm 5 positioned between the structural column 72 and the attaching column 74. The hydraulic telescopic rod 13 is extended to raise the base 1 until the moving wheel 11 is suspended. The second telescopic tube 42 is then extended to force the contact plate 44 into contact with the roof of the factory, thereby positioning the device and reducing the risk of the base 1 slipping during construction.

[0065] The building block 75 is moved between the clamping column 74 and the structural column 72, and the clamping grooves 751 on both sides of the building block 75 are clamped with the clamping column 74 and the structural column 72 respectively, and then the lifting arm 5 performs the lifting work until the top end of the building block 75 abuts against the crossbeam 77.

[0066] When the building block 75 is lifted on the lifting arm 5, the clamping column 74 and the structural column 72 limit the building block 75, reducing the possibility of the building block 75 tipping over or shifting when being lifted upward on the lifting arm 5. The structural column 72 and the clamping column 74 can assist in the installation of the building block 75.

[0067] S3. Fixed block 75: refer to Figure 6A fixing part 76 is provided between the block 75 and the structural column 72 and the clamping column 74. The fixing part 76 is an L-shaped angle iron. When the block 75 contacts the upper crossbeam 77 or the block 75 through the lifting arm 5, the construction platform 3 rises, and the construction workers stand on the construction platform 3 and contact one side of the L-shaped angle iron with the bottom surface of the block 75, and weld the other side of the L-shaped angle iron to the side wall of the fixed column or the clamping column 74. The L-shaped angle iron plays a role in fixing the block 75. Compared with the traditional mortar masonry method, fixing the block 75 with the L-shaped angle iron can save construction time and reduce construction costs. In the process of fixing the block 75 with mortar, construction waste and dust will be generated. In comparison, the solution of the present application is more in line with the requirements of green construction, and is not easy to generate dust during the construction process, thereby protecting the environment.

[0068] After the building block 75 is fixed between the clamping column 74 and the structural column 72, the filler is sprayed on the connection of the building block 75, and the gaps between the building block 75 and the beam 77, the building block 75 and the structural column 72, and the building block 75 and the clamping column 74 are sprayed with filler to fill the gaps between the building block 75 and the adjacent structures, so that the building block 75 and the surrounding structures are more tightly combined. In this embodiment, the filler can be grout or caulking agent and other materials with adhesive force. The filler tube can also increase the bonding strength between the building block 75 and the surrounding structures, so that the connection between the building block 75 and the surrounding structures is more firmly.

[0069] S4. Installing the waist beam 73: Install the building blocks 75 from top to bottom to form the wall. When the building blocks 75 are installed near the waist beam 73, weld one end of the waist beam 73 vertically to the side wall of the structural column 72, and weld the other end of the waist beam 73 to the side wall of the clamping column 74. The adjacent edges of the building blocks 75 adjacent to the waist beam 73 are each provided with a fixing groove 752 that clamps with the waist beam 73, ensuring a more secure connection between the building blocks 75 and the waist beam 73.

[0070] Repeat the above operation process. When the building blocks 75 are installed to form a wall, the lifting arm 5 is disassembled, and the construction workers stand on the construction platform 3 and adjust the height of the construction platform 3 to perform plastering or painting on the wall.

[0071] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
