Description

Technical Field

[0001] This invention belongs to the technical field of wall masonry devices, and specifically relates to a two-structure wall masonry device and construction method. Background Technology

[0002] After the main structure of the prefabricated building is completed, the space is divided by building secondary structural walls. There is a lot of masonry work on the construction site, and the quality of the wall construction is one of the key processes that affect the aesthetics of the building. The difficulty is especially in controlling the quality of the wall construction and the safety of construction on the open surfaces above the second floor.

[0003] Currently, the on-site masonry construction method for structures with exposed sides involves first erecting a large amount of scaffolding on one side of the exposed surface as a safe construction platform for subsequent masonry and wall leveling work. For cantilevered sections or high-rise buildings, a large number of scaffolding frames and supports are erected sequentially upwards, resulting in high material and construction costs and significant safety hazards associated with working at heights. During block masonry, since the tie bars are pre-welded to the steel columns, it is often difficult to precisely control the tie bars at the mortar joint gaps during actual block construction. When the position of the tie bars deviates under this construction method, it is not easy to adjust. On-site workers often forcibly adjust the position by bending the steel bars, which greatly weakens the tie effect of the steel bars. At the same time, it is difficult to make secondary repairs after wall leveling work is carried out during exposed work, and the appearance quality is difficult to guarantee. After the masonry is completed, it is difficult to adjust the verticality and flatness of the wall, resulting in difficulties in controlling the quality of wall construction. Summary of the Invention

[0004] In order to reduce scaffolding construction, lower costs, and improve construction safety and quality during the construction of two-structure walls, this invention provides a two-structure wall construction device and construction method.

[0005] The technical solution of the present invention is as follows:

[0006] A two-structure wall masonry device, comprising:

[0007] A track assembly, at least a portion of which is vertically and retractably positioned below the steel frame to be built, for supporting the precast wall;

[0008] A base plate is movably mounted on the track assembly to support and move the precast wall.

[0009] A masonry formwork is used to assist in the construction of precast walls, and the masonry base plate is located inside or below the masonry formwork.

[0010] Furthermore, the orbital assembly includes:

[0011] A track frame is set on the ground where the wall is to be built, along the direction of movement of the precast wall;

[0012] A plurality of movable bases are provided, which are vertically and vertically mounted on the track frame for adjusting the height of the track frame and moving the track frame.

[0013] Two guide rails are spaced apart on the track frame for the masonry base plate to move along the track frame.

[0014] Furthermore, the track frame includes two longitudinal beams and several transverse beams, wherein the transverse beams are spaced apart between the two parallel longitudinal beams for connecting the two longitudinal beams.

[0015] The movable bases are evenly spaced at the bottom of the two longitudinal beams;

[0016] Each of the aforementioned guide rails is positioned on top of a longitudinal beam.

[0017] Furthermore, the wall construction device also includes multiple spaced blocks, which are used to support the precast wall from below after it reaches the design position to facilitate the demolding of the base plate.

[0018] The masonry base plate is movably mounted on the guide rail, and the side of the masonry base plate facing the exterior facade of the wall is provided with multiple intermittent grooves running vertically to avoid multiple pad blocks.

[0019] Furthermore, the movable base is equipped with a hydraulic lifting device and casters.

[0020] Furthermore, the masonry formwork is equipped with a brick gauge rod to control the number of brick courses and the thickness of the brick joints in the precast wall; and / or,

[0021] The masonry formwork is also equipped with a monitoring camera to identify the depth and fullness of the mortar joints in order to monitor the quality of the wall plastering.

[0022] A construction method for building a two-structure wall includes the following steps:

[0023] S1. Construct the wall on the masonry base slab, pre-embed tie bars in the wall, and open welding holes;

[0024] S2. Perform wall treatment;

[0025] S3. Move the precast wall to the designed wall position;

[0026] S4. Lower the wall, adjust its verticality, weld the tie bars, and move the wall construction device out from under the wall.

[0027] S5. Grouting and sealing of welding holes, grouting and fixing of the bottom of the wall, and completion of the masonry of the secondary structural wall.

[0028] Furthermore, prior to step S1, the following is also included:

[0029] S0. Install a wall construction device on the indoor floor of the building along a direction perpendicular to the two structural walls;

[0030] The process after step S5 also includes:

[0031] S6. Dismantle the wall construction device or move the wall construction device to the next work point.

[0032] Furthermore, in step S3, moving the prefabricated wall to the designed wall position includes:

[0033] Using the aforementioned wall construction device, under the action of the guide rail, the precast wall is moved along the longitudinal beam direction of the track frame to the designed wall position via the construction base plate; and / or,

[0034] Step S3 also includes: placing a pad below the designed position of the wall; Step S4 also includes: lowering the wall onto the pad.

[0035] Furthermore, in step S4, lowering the wall onto the pad includes:

[0036] Using the aforementioned wall construction device, the height of the movable base is lowered by a hydraulic lifting device, causing the construction base plate to detach from the bottom of the precast wall, and the bottom of the wall to sit on the pad block.

[0037] The beneficial effects of this invention are as follows:

[0038] This invention discloses a two-structure wall construction device and method. The device allows for prefabrication of walls within a building's interior. For cantilevered sections or high-rise two-structure construction, it eliminates the need for extensive scaffolding, effectively reducing material and construction costs. Furthermore, it eliminates the need for high-altitude work on scaffolding, lowering safety hazards. In the construction method, tie bars are pre-embedded within the wall, eliminating the need for later adjustments and maximizing their strength. The wall surface can be smoothed during prefabrication, eliminating the need for secondary repairs and improving construction quality. Additionally, adjusting the wall's verticality and flatness before fixing it to the building frame further enhances construction quality. Attached Figure Description

[0045] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] Example 1:

[0050] refer to Figures 1 to 4 The embodiment provides a two-structure wall masonry device, including: a track assembly 1, a masonry base plate 2 and a masonry formwork 3, and may also include multiple pads 4.

[0051] The track assembly 1 is used to lift and lower at least part of the steel frame to be built, to support the precast wall, and to move and position the precast wall, thereby improving work efficiency.

[0052] The base plate 2 is movably mounted on the track assembly 1 to support and move the precast wall.

[0053] The masonry formwork 3 is used to assist in the construction of precast walls. The masonry base plate 2 is located inside or below the masonry formwork 3. When the masonry base plate 2 is located inside the masonry formwork 3, the masonry formwork 3 can be erected on the ground below the masonry base plate 2. When the masonry base plate 2 is located below the masonry formwork 3, the masonry formwork 3 can be erected on the masonry base plate 2.

[0054] The two-structure wall construction device provided in this embodiment allows for the prefabrication of walls inside the building. For cantilevered sections or high-rise two-structure construction, there is no need to erect a large amount of scaffolding, which can effectively reduce the input of materials and construction costs. Furthermore, it eliminates the need for high-altitude operations on tall scaffolding, thus reducing safety hazards.

[0055] In a preferred embodiment, the track assembly 1 includes: a track frame 101, a plurality of movable bases 102 and two guide rails 103.

[0056] The track frame 101 is set on the ground of the wall to be built along the direction of movement of the precast wall. The track frame 101 includes two longitudinal beams and several transverse beams. The transverse beams are spaced apart between the two parallel longitudinal beams to connect the two longitudinal beams. The track frame 101 serves as the load-bearing structure of the entire track assembly 1. Both the transverse beams and the longitudinal beams can be made of steel pipes.

[0057] Several movable bases 102 are elliptically mounted on the track frame 101 for adjusting the height of the track frame 101 and moving the track frame 101. The movable bases 102 are evenly spaced at the bottom of the two longitudinal beams. The movable bases 102 are equipped with hydraulic lifting devices and moving wheels. The hydraulic lifting devices can be hydraulic cylinders, which can adjust the height of the track frame 101. The maximum height of the movable base 102 is higher than the height of the wall pad 4, and the minimum height of the lowering is lower than the height of the wall pad 4. The moving wheels can be casters, which can move the track frame 101 so as to remove the track assembly 1 and the masonry base plate 2 from the bottom of the wall, or transfer the wall masonry device.

[0058] Two guide rails 103 are spaced apart on the track frame 101 for the masonry base plate 2 to move along the track frame 101. Each guide rail 103 is located on the top of a longitudinal beam.

[0059] Multiple spacers 4 are placed at intervals at the designed positions on the wall. The spacers 4 are used to support the precast wall from below after it reaches the designed position, facilitating the demolding of the base slab 2. The spacers 4 can be precast concrete blocks, prefabricated on-site, placed under the wall to provide support for positioning the precast wall. Simultaneously, they leave space at the bottom of the wall for grouting, allowing for a wet connection between the wall and the structure. After the grout solidifies, it reinforces the wall. The height of the spacers 4 is generally around 20cm.

[0060] The masonry base plate 2 is movably mounted on the guide rail 103. The masonry base plate 2 moves on the guide rail 103 driven by a motor. The side of the masonry base plate 2 facing the exterior facade of the wall has multiple vertically spaced grooves 201. Figure 3 As shown, the groove 201 is used to avoid multiple pad blocks 4. When the masonry base plate 2 is moved to the designed position, the pad blocks 4 pass through the groove 201. After the pad blocks 4 support the precast wall from below, the demolding operation can be completed by moving the masonry base plate 2.

[0061] As a preferred implementation, a brick gauge (not shown) can be installed on the masonry formwork 3 to control the number of brick courses and the thickness of the brick joints in the precast wall. During construction, the flatness and verticality of the wall surface can be controlled by laser. A monitoring camera (not shown) can also be installed on the masonry formwork 3 to identify the depth and fullness of the mortar joints, thereby monitoring the quality of the wall smoothing and improving the construction quality of the secondary structure wall.

[0062] Example 2:

[0063] refer to Figure 5 This embodiment provides a wall construction method using the two-structure wall masonry device as described in Embodiment 1, which includes the following steps: S1-S5, and may also include S0 and S6.

[0064] S0. Install a wall construction device on the indoor floor of the building along a direction perpendicular to the two structural walls.

[0065] S1. Construct a wall on the masonry base slab 2, and pre-embed tie bars 5 in the wall and open welding holes 6. By pre-embedding the tie bars 5 in the wall and then welding them together, the problem of mismatch between the height of the tie bars 5 and the number of masonry blocks during traditional two-structure masonry is solved.

[0066] S2. Perform wall treatment, which may include wall plastering and wall curing. Inspect the appearance quality of the wall and repair it in a timely manner. After the wall curing is completed and the wall has formed strength, it can be connected to the main components. This effectively avoids the damage caused by uneven stress due to material deformation during the curing period of traditional two-structure masonry. While curing the precast wall, remove the masonry formwork 3 to facilitate the subsequent movement of the precast wall or the demolding of the precast wall.

[0067] S3. Place pad block 4 on the ground below the designed wall position and move the precast wall to the designed wall position.

[0068] As a preferred embodiment, moving the prefabricated wall to its designed location includes:

[0069] Using the wall construction device as described in Example 1, the precast wall is moved to the designed position along the longitudinal beam of the track frame 101 by the construction base plate 2 under the action of the guide slide rail 103.

[0070] S4. Place the wall on the pad 4, adjust the verticality of the wall, weld the tie bar 5, and move the wall masonry device out from under the wall. During construction, the verticality of the wall can be adjusted and fixed with the help of diagonal bracing tools.

[0071] In a preferred embodiment, the wall is placed onto the pad 4, including:

[0072] Using the wall construction device as described in Example 1, the height of the movable base 102 is lowered by a hydraulic lifting device, so that the construction base plate 2 is separated from the bottom of the precast wall and the bottom of the wall sits on the pad 4.

[0073] S5, Welding hole 6 is grouted and sealed, and the bottom of the wall is grouted and fixed to complete the masonry of the secondary structural wall.

[0074] S6. Dismantle the wall construction device or move the wall construction device to the next work point.

[0075] In the construction method of the two-structure wall in this embodiment, the tie bar 5 is pre-embedded in the wall, eliminating the need for subsequent adjustment of the tie bar 5 position and maximizing the retention of the tie bar 5's tensile strength. Furthermore, the wall surface can be smoothed during the prefabrication process, eliminating the need for secondary repairs and improving construction quality. In addition, the verticality and flatness of the wall surface are adjusted before the two-structure wall is fixed to the building frame, further improving construction quality.

[0076] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
