Description

Technical Field

[0002] As one of the structural types of prefabricated buildings, prefabricated buildings are widely used in various types of buildings. Their main structural components are prefabricated in factories and assembled on site. When installing vertical prefabricated components, the method of "aligning the outer contour of the wall base and the center line of the wall top" is adopted to ensure that the installation space position of the exterior wall components is accurate while ensuring the exterior wall is flush. Among them, "aligning the outer contour of the wall base" can ensure that after the construction of the building facade is completed, that is, after the cavity and node parts are poured and filled with concrete, there is no "misalignment" phenomenon at the connection nodes of the upper and lower walls.

[0003] Therefore, after a stage of prefabricated component construction is completed, it is necessary to detect the flatness of the outer contour of the prefabricated component installation to avoid misalignment between the upper and lower walls. The misalignment between the upper and lower walls needs to be measured. The current measuring tools are operated by hand, which is convenient and fast, but requires operators to work along the edge or even lean out of the building to carry out construction, which poses a safety hazard of falling from heights.

[0017] 1. The prefabricated components of the prefabricated building are installed with an outer contour flatness detection device. The wire is manually lowered and the structure is slowly unwound, and the weighted shot slowly moves downward. By controlling the falling speed of the weighted shot, the weighted shot is prevented from moving under inertia after being subjected to force, so that the change in the movement direction of the weighted shot that conflicts with the prefabricated building body is mainly caused by the change in direction caused by the change in the cross-section of the prefabricated building body.

The rotating connecting plate component 3 drives the winding frame to rotate through the transmission shaft 1 to control the winding frame to reel in or unwind the wire. The staff can use the flatness detection structure to detect the flatness of the outer contour of the prefabricated component without electricity. The external threaded component 1 moves to push the friction plate 1 to move toward the L-shaped support plate. Finally, the friction plate 1 resists the L-shaped support plate to generate friction. At this time, the rotation of the friction plate 1 is limited, the rotation of the connecting plate component 3 is limited, the rotation of the winding frame is limited, the unwinding of the wire is terminated, and the downward movement of the weighted lead shot is terminated.

[0019] 3.

DETAILED DESCRIPTION

[0033] Specifically, by holding the handle (4) fixedly connected to one side of the L-shaped support plate (21) in the flatness detection structure (2), the staff can lift the flatness detection structure (2) through the handle (4), and then place the flatness detection structure (2) on the assembled prefabricated component building body (1). Figure 2 As shown, the protection box (213) and the positioning plate (26) in the flatness detection structure (2) are respectively arranged on both sides of the assembled prefabricated component building body (1);

[0034] Subsequently, the staff member pulls the L-shaped support plate (21) through the handle (4), so that the two arc-shaped plates (27) symmetrically fixedly connected at one end of the inner side of the L-shaped support plate (21) away from the assembled prefabricated component building body (1) move toward the assembled prefabricated component building body (1), and a weighted lead ball (210) is arranged between the two arc-shaped arc-shaped plates (27), and the outer partial curved surface of the weighted lead ball (210) is arranged inside the arc-shaped concave interior of the two arc-shaped plates (27), so that the arc-shaped plates (27) can The elastic support assembly is provided between the L-shaped support plate (21) and the two positioning plates (26); during the movement of the L-shaped support plate (21), the positioning plates (26) abut against the assembled prefabricated component building body (1), so that the movement is limited; at this time, the elastic support assembly is extended, and the positioning plates (26) abut against the assembled prefabricated component building body (1) without affecting the movement of the L-shaped support plate (21);

[0035] Furthermore, a connecting plate member 2 (28) is fixedly connected to one side of each of the two arc-shaped plates (27), and one end of each of the two connecting plate members 2 (28) is fixedly connected to a pressure sensor (29). One side of the pressure sensor (29) supported by the two connecting plate members 2 (28) and the weighted lead ball (210) simultaneously contact one side of the assembled prefabricated component building body (1). When the pressure sensor (29) contacts the assembled prefabricated component building body (1), the pressure sensor (29) is pressed, and a display (232) electrically connected to the pressure sensor (29) receives feedback from the pressure sensor (29). At this time, the pressure sensor (29) controls the electrical The manually lowerable structure connected thereto works, and at this time, the forward and reverse motor (214) in the manually lowerable structure works, and the forward and reverse motor (214) drives the winding frame (216) fixedly connected to the output end to rotate. Since one end of the pull wire (211) is fixedly connected to the winding frame (216) and the pull wire (211) is partially wrapped around the winding frame (216), the winding frame (216) rotates to unwind the pull wire (211), and the pull wire (211) is fixed to the top center of the weighted lead shot (210), and the pull wire (211) passes through the wire tube (212) fixedly connected to the L-shaped support plate (21), and the wire tube (212) is set to be U-shaped, such as Figure 1As shown, under the limiting guidance of the wire tube (212), the end of the pull wire (211) fixed to the weighted lead ball (210) is vertically downward, so the weighted lead ball (210) is subjected to a vertical downward force under the influence of gravity;

[0036] As the tension wire (211) is slowly unwound by the manually lowerable structure, the weighted lead ball (210) slowly moves downward. By controlling the falling speed of the weighted lead ball (210), the weighted lead ball (210) is prevented from moving under inertia after being subjected to force, so that the movement direction of the weighted lead ball (210) that contacts the assembled prefabricated component building body (1) changes mainly due to the change in direction caused by the blockage of the cross-sectional change of the assembled prefabricated component building body (1). If the assembled prefabricated component building body (1) is inclined, the weighted lead ball (210) moves left and right under the action of the assembled prefabricated component building body (1). At the same time, the laser lamp (230) fixedly connected to the weighted lead ball (210) keeps working. The laser lamp (230) emits laser light to irradiate the focusing plate (223). The working camera (231) captures the left and right position change of the laser light on the focusing plate (223). The display (231) 2) receiving an image captured by an electrically connected camera (231), and since the unwinding distance of the pull wire (211) can be calculated based on the working time of the forward and reverse motors (214), the display (232) can easily calculate the downward movement distance of the weighted shot put (210). The display (232) can generate a statistical graph with the X-axis being the downward movement distance of the weighted shot put (210) and the Y-axis being the left and right movement distance of the weighted shot put (210) based on the image captured by the camera (231) and the downward movement distance of the weighted shot put (210), so that the detection result of the flatness of the outer contour of the prefabricated component of the assembled prefabricated component building body (1) can be displayed more clearly, making it convenient for workers to arrange the construction of the prefabricated components; and the workers do not need to lean out to the side of the assembled prefabricated component building body (1) to view the position of the weighted shot put (210), thereby reducing safety hazards and reducing judgment errors.

[0037] At the same time, the external threaded member 2 (31) in the rotating clamping structure (3) is rotated because the connecting plate member 7 (33) sleeved on the outer side of the external threaded member 2 (31) is fixedly connected to the L-shaped support plate (21), so the external threaded member 2 (31) can rotate, and the connecting plate member 6 (32) sleeved on the outer side of the external threaded member 2 (31) is fixedly connected to the connecting frame (35) on both sides, and the two connecting frames (35) both penetrate the L-shaped support plate (21), and two friction plates 2 (34) are fixedly installed between the two connecting frames (35), and one end of the rotating external threaded member 2 (31) is rotatably connected to one friction plate 2 (34), and the two friction plates The two friction plates (34) are integrally arranged under the action of the connecting frame (35) and the connecting plate member (32), so that the two friction plates (34) move toward the assembled prefabricated component building body (1) at the same time, and the friction plates (34) are pressed against one side of the assembled prefabricated component building body (1). The two positioning plates (26) are pressed against the other side of the assembled prefabricated component building body (1) by the elastic support assembly. The L-shaped support plate (21) is installed on the assembled prefabricated component building body (1), and the flatness detection structure (2) can be installed on the assembled prefabricated component building body (1), thereby avoiding the possibility of the weighted shot (210) moving left and right due to hand shaking of the staff.

Therefore, after the positioning plates (26) abut against the assembled prefabricated component building body (1), the L-shaped support plate (21) is continuously pulled to drive the weighted lead ball (210) to move toward the assembled prefabricated component building body (1). At this time, the plurality of spring-type telescopic rods (23) are extended. When the positioning plates (26) are blocked by the assembled prefabricated component building body (1), the movement of the L-shaped support plate (21) is not restricted.

[0039] In addition, such as Figure 1As shown, a protection frame (233) is fixedly mounted on one side of the L-shaped support plate (21), and the display (232) is mounted inside the protection frame (233), thereby reducing the possibility of collision between the display (232) and the building, and providing protection for the display (232) used at the construction site.
