Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for the construction of prefabricated building wall panels, and specifically to a support device for prefabricated building wall panels. Background Technology

[0002] In the installation of prefabricated building wall panels, after the panels are placed in their pre-set positions, they need to be reinforced to ensure accuracy and stability. During this reinforcement process, auxiliary equipment is used to temporarily fix the panels, facilitating the workers' reinforcement. Existing temporary fixing auxiliary equipment is mostly a fixed structure, unable to flexibly adapt to wall panels of different thicknesses. Instead, it involves drilling holes in the wall panels and then connecting them to the supporting structure or building structure using bolts, pins, and other connectors. This method has significant drawbacks: drilling holes damages the original structural integrity of the wall panel, weakens its mechanical properties, and may also cause the insulation and waterproofing functions to fail, leaving safety hazards. Summary of the Invention

[0003] The technical problem to be solved by this utility model is how to fix wall panels of different thicknesses and avoid damage to the wall.

[0004] The technical solution adopted by this utility model is: a prefabricated building wall panel support device, including a wall panel placed in a pre-installation position, characterized in that a fixing plate and a limiting frame are installed on one side of the wall panel, wherein the fixing plate is spaced apart from the wall panel and installed on a horizontal floor slab, the limiting frame is installed on the top of the wall panel, the limiting frame is "L" shaped, the top of the limiting frame is provided with a sliding cavity, the sliding cavity is provided with a fixing rod, the fixing rod is slidably connected to a sliding member, the bottom of the sliding member is "L" shaped and used to abut against the top of the wall panel, the side of the limiting frame is provided with a positioning cavity, the positioning cavity is connected with a positioning column, the positioning column is provided with a pushing elastic member and a ball, the side of the sliding member near the positioning cavity is connected with a pull rod passing through the side wall of the limiting frame, the pull rod is provided with multiple positioning grooves, the positioning grooves cooperate with the ball, and a first support mechanism is provided between the fixing plate and the limiting frame.

[0005] The above structure has the following beneficial effects:

[0006] (1) The sliding part is guided by the sliding cavity and the fixed rod set at the top of the limiting frame, so that the sliding part can slide freely along the fixed rod. The pull rod connected to the sliding part can move the position of the sliding part while the worker moves the pull rod. When the wall panel is to be fixed, the "L" shaped structure at the bottom of the sliding part can fit tightly against the top of the wall panel as the sliding part moves along the direction of the wall panel. When the wall panel thickness is different, the limiting position can be adjusted according to the wall panel of different thicknesses. There is no need to customize the device separately for wall panels of specific sizes, which greatly improves the versatility of the device.

[0007] (2) By setting a positioning cavity on the limit frame and setting a positioning column in the positioning cavity, the ball is continuously pushed by the push elastic element in the positioning cavity, so that it is locked into the positioning groove of the pull rod. This can quickly lock the adjustment position of the sliding part, avoid the sliding part from shifting during construction and causing the top limit to fail. At the same time, when unlocking, the ball can be disengaged from the groove by simply pulling the pull rod, which is convenient to operate.

[0008] Preferably, the positioning post has a protrusion at one end where the ball is located to prevent it from falling off.

[0009] By setting an anti-drop protrusion at the end of the positioning post where the ball is located, the range of motion of the ball can be effectively limited, preventing the ball from falling out of the positioning post due to the continuous force of the pushing elastic element or the vibration of the device. This ensures that the ball always stays in contact with the pull rod, stably cooperating with the positioning groove to achieve the positioning of the pull rod, and preventing the position of the sliding element from changing due to the ball falling out.

[0010] Preferably, the limiting frame has a knob threaded end on its side, the knob threaded end has a thread on its outer side, the knob threaded end has a circular through hole inside, the pull rod passes through the circular through hole, the end face of the knob threaded end has a diaphragm, the diaphragm has a multi-lobed structure, and a locking knob is connected to the outer wall of the knob threaded end, the locking knob has a hollow frustum shape inside.

[0011] The limit bracket has a knob threaded end with a circular through hole on its side, through which the pull rod passes. It works in conjunction with a multi-lobed diaphragm and a locking knob in the hollow frustum. When the locking knob is turned, the inner wall of the frustum can compress the multi-lobed diaphragm to contract, causing the diaphragm to grip the pull rod. This structure provides a double lock for the pull rod based on ball positioning, further enhancing the positional stability of the pull rod and the sliding component. It can also compensate for situations where ball positioning fails, such as when the wall plate thickness is inconsistent, causing the ball to fail to embed in the positioning groove.

[0012] Preferably, the end of the diaphragm valve is provided with an annular protrusion, which is used to abut against the pull rod.

[0013] By setting an annular protrusion at the end of the diaphragm, the time required to turn the locking knob can be effectively shortened, allowing the diaphragm to come into contact with the pull rod more quickly. At the same time, the diaphragm is subjected to stronger pressure from the locking knob, further improving the locking effect.

[0014] Preferably, the first support mechanism includes a first connecting rod and two first sliding rods, with the two first sliding rods slidably connected to both sides of the first connecting rod.

[0015] By setting first sliding rods on both sides of the first connecting rod, the overall length of the first support mechanism can be flexibly adjusted. This design can adapt to different installation distances between the fixed plate and the limiting frame, such as differences in wall panel size and deviations in the reserved position of the floor slab, which significantly improves the adaptability of the device.

[0016] Preferably, the bottom of the wall panel abuts against a connecting member, and a second support mechanism is provided between the connecting member and the first connecting rod. The second support mechanism includes a second connecting rod and a second sliding rod. The second connecting rod is rotatably connected to the first connecting rod, and the second connecting rod is slidably connected to the second sliding rod.

[0017] By setting an abutment at the bottom of the wall panel and having it abut against the wall panel, the wall panel is limited. Then, a second support mechanism connects the first support mechanism and the abutment, achieving coordinated fixation of the wall panel at two points: the top limiting frame and the bottom abutment. At the same time, the second support mechanism can be adjusted in angle and length according to actual needs to accommodate the positional deviation between the wall panel abutment and the first support structure, making the support force on the wall panel more balanced. This effectively prevents the wall panel from tilting due to uneven force during pre-installation and effectively improves the stability of the wall panel fixation.

[0018] Preferably, a through hole is provided on the top surface of both the first connecting rod and the second connecting rod, and a rectangular groove is provided on both sides of the through hole. An arc-shaped groove is provided at the end of the first sliding rod near the first connecting rod and at the end of the second sliding rod near the second connecting rod. Two limiting levers are rotatably connected in the arc-shaped grooves, and the limiting levers cooperate with the rectangular grooves.

[0019] By providing through holes with rectangular grooves on the top surfaces of the first and second connecting rods, and arc-shaped grooves at the ends of the first and second sliding rods, and by providing a limiting lever that is rotatably connected to the arc-shaped grooves, the sliding rod can be quickly locked in position by simply rotating the limiting lever to engage with the rectangular groove after it has been adjusted to the appropriate position. This locking method requires no additional tools, is simple and convenient to operate, and can significantly shorten the time for length adjustment and fixing of the support mechanism, thereby improving installation efficiency. At the same time, the stable cooperation structure between the rectangular groove and the limiting lever can effectively prevent the sliding rod from loosening under force, ensuring a constant support length.

[0020] Preferably, the first connecting rod is provided with a partition, and pre-tightening elastic members are provided on both sides of the partition and inside the second connecting rod. One end of the pre-tightening elastic member on both sides of the partition abuts against the partition, and the other end abuts against the side wall of the first connecting rod. One end of the other pre-tightening elastic member provided inside the second connecting rod abuts against the inner wall of the second connecting rod, and the other end abuts against the side wall of the second sliding rod.

[0021] By setting pre-tightening elastic elements on both sides of the partition inside the first connecting rod and inside the second connecting rod, a continuous pre-tightening force can be applied to the first sliding rod and the second sliding rod. This ensures that even if the sliding rod is slightly displaced due to vibration after adjustment and locking, it can be pressed and reset by the pre-tightening elastic elements, thus preventing gaps in the support mechanism that could lead to loosening of the support.

[0022] Preferably, the partition and the side wall of the first sliding rod, the inner wall of the second connecting rod and the side wall of the second sliding rod are all provided with circular grooves, and the two ends of the pre-tightening elastic member are respectively embedded in the corresponding circular grooves.

[0023] By setting circular grooves on the partition, the side wall of the first sliding rod, the inner wall of the second connecting rod, and the side wall of the second sliding rod, the two ends of the pre-tightening elastic element are embedded in the grooves. This allows for precise positioning of the pre-tightening elastic element, preventing it from shifting or twisting when it is under stress. It ensures that the pre-tightening elastic element always applies pre-tightening force to the sliding rod in the preset position, avoiding the failure of the pre-tightening function due to misalignment of the pre-tightening elastic element, and effectively improving the structural stability and reliability of the support mechanism.

[0024] Preferably, a pull ring is connected to the end of the pull rod away from the slider.

[0025] By installing a pull ring at the end of the pull rod away from the slider, workers can directly pull the pull rod to adjust the position of the slider, improving the convenience of slider adjustment and increasing overall installation efficiency. Attached Figure Description

[0039] Example

[0040] The following description, in conjunction with specific embodiments, provides further details. Figure 1-9As shown, this embodiment is a prefabricated building wall panel support device, including a wall panel 10 already placed in a pre-installation position. A fixing plate 20 and an abutment member 30 are installed on one side of the wall panel 10. The fixing plate 20 is a certain distance away from the wall panel 10 and is fixed to a horizontal floor slab by bolts. The bolts are arranged on both sides of the fixing plate 20. The fixing plate 20 is made of high-strength rectangular steel plate. The abutment member 30 abuts against the wall panel 10. The abutment member 30 is made of "L"-shaped steel plate, and an anti-slip pad is attached to the numerical end face that contacts the wall panel 10. The surface of the anti-slip pad has anti-slip texture to enhance the contact between the abutment member 30 and the wall panel 10. Friction between them; A limit frame 40 is installed on the top of the wall panel 10. The limit frame 40 is "L"-shaped and made of high-strength metal. The top of the limit frame 40 is provided with a sliding cavity 41. A fixed rod is provided in the sliding cavity 41. The fixed rod is also made of high-strength metal. A sliding member 42 is installed on the fixed rod. The top of the sliding member 42 is slidably connected to the fixed rod. In addition, a reset elastic member 411 is also sleeved on the fixed rod. The reset elastic member 411 is a cylindrical helical spring. One end of the reset elastic member 411 abuts against the inner wall of the sliding cavity 41, and the other end of the reset elastic member 411... The sliding member 42 abuts against the top side wall of the sliding member 42, and the bottom of the sliding member 42 is also designed in an "L" shape to facilitate abutment against the wall panel 10; a knob threaded end 47 is provided on the side of the limiting bracket 40, the outer side of the knob threaded end 47 is threaded, and the inside is a circular through hole 70. A pull rod 43 is welded and fixed to the side of the sliding member 42 near the knob threaded end 47. The pull rod 43 passes through the circular through hole 70 inside the knob threaded end 47, and a pull ring 431 is threadedly connected to the end of the knob threaded end 47 away from the sliding member 42, so as to facilitate pulling the sliding member 42 through the pull ring 431; in addition, the knob A diaphragm 471 is fixed to the end face of the threaded end 47 by welding. The diaphragm 471 is made of elastic metal material and can deform with continuous external force. When the external force is removed, it can return to its original shape. In this embodiment, the diaphragm 471 has multiple petals and an annular protrusion at the end of the petal body, which can abut against the pull rod 43. The outer wall of the knob threaded end 47 is threaded with a locking knob 48. The inside of the locking knob 48 is a hollow frustum, which makes it easy to fit tightly against the diaphragm 471 when rotating. As the locking knob 48 rotates continuously, the diaphragm 471 moves towards the pull rod 43 until the diaphragm 471 locks the pull rod 43.A positioning cavity 44 is provided above the threaded end 47 of the knob, while multiple positioning grooves 45 are provided on the pull rod 43. A positioning post 46 is threadedly connected to the positioning cavity 44. The positioning post 46 contains a push elastic element 461 and a ball 462. The push elastic element 461 is a cylindrical helical spring. The end of the positioning post 46 with the ball 462 has a protrusion that tightens towards the ball 462 to prevent the ball 462 from falling off. Under the action of the push elastic element 461, the ball 462 always fits against the pull rod 43. When the pull rod 43 moves to the position with the positioning groove 45, the ball 462 will partially embed into the positioning groove 45, thereby fixing the pull rod 43.

[0041] The limiting frame 40 and the fixing plate 20 are connected by a first support mechanism, and the first support mechanism and the abutment member 30 are connected by a second support mechanism. The first support mechanism includes a first connecting rod 51 and a first sliding rod 52. Two first sliding rods 52 are provided, respectively located on both sides of the first connecting rod 51. A partition is provided inside the first connecting rod 51, and pre-tensioning elastic elements 53 are provided on both sides of the partition. The pre-tensioning elastic elements 53 are also cylindrical helical springs. One end of the pre-tensioning elastic element 53 abuts against the partition, and the other end abuts against the side wall of the first connecting rod 51. To prevent the positions of the two ends of the pre-tensioning elastic element 53 from shifting, pre-tensioning elastic elements are provided on both the partition and the side wall of the first connecting rod 51. A circular groove is provided so that both ends of the pre-tightening elastic element 53 are embedded in the circular groove; a through hole 70 is also provided on the top surface of the first connecting rod 51. In this embodiment, the through hole 70 is a rectangular through hole 70. Rectangular grooves 71 are also provided on both sides of the through hole 70. Due to the setting of the rectangular grooves 71, the two sides of the through hole 70 form a complementary structure; an arc-shaped groove 80 is provided at one end of the first sliding rod 52 near the first connecting rod 51. Two limiting levers 90 are rotatably connected in the arc-shaped groove 80. When the first sliding rod 52 is adjusted to a suitable position, the two limiting levers 90 are moved in different directions so that the limiting levers 90 are locked in the rectangular grooves 71, thereby completing the fixation of the position of the first sliding rod 52.

[0042] The second support mechanism includes a second connecting rod 61 and a second sliding rod 62. The second connecting rod 61 is rotatably connected to the first connecting rod 51, and the second connecting rod 61 is slidably connected to the second sliding rod 62. Similar to the fixing method between the first connecting rod 51 and the first sliding rod 52 in the first support mechanism, the top surface of the second connecting rod 61 is also provided with another through hole 70 and a rectangular groove 71. The second sliding rod 62 is also provided with another arc-shaped groove 80 and a limiting lever 90. When the second sliding rod 62 moves to a suitable position, the second sliding member 42 is fixed by rotating the corresponding rectangular groove 71 of the limiting lever 90. The end of the second sliding rod 62 away from the second connecting rod 61 is rotatably connected to the abutment 30.

Fix the pull rod 43; then install the first support frame between the fixed plate 20 and the limiting frame 40, and then adjust the position of the first sliding member 42. When it is adjusted to a suitable position, rotate the limiting lever 90 to fix the position of the first sliding member 42. Then install the second support mechanism between the first connecting rod 51 and the abutment member 30. Similarly, adjust the position of the second sliding rod 62 until it is adjusted to a suitable position. Then rotate the limiting lever 90 set on the second sliding rod 62 to fix the second sliding rod 62.
