Description

Technical Field

[0001] The invention relates to the technical field of side support equipment, in particular to a side support device for installing a prefabricated wall panel. Background Art

[0002] Prefabricated wall panels are an important component of prefabricated buildings. During on-site installation, how to fix the prefabricated wall panels conveniently and efficiently while ensuring that the wall panels do not shake slightly after being fixed is a major problem that many people in the industry are currently working hard to solve. Therefore, after the building wall panels are assembled, the wall panels must be supported to ensure that the wall panels do not shake slightly after being fixed. Currently, inclined support rods are mostly used. The inclined supports on the market usually consist of two parts: a threaded rod and a sleeve. The length of the inclined support is adjusted through the threaded connection between the threaded rod and the sleeve for fine-tuning of the wall during the wall support process, thereby ensuring that the wall is always in a vertical state and avoiding wall shaking.

[0003] The Chinese patent publication number CN217129028U discloses an assembled exterior wall panel diagonal support structure, which adjusts the overall length of the diagonal support member by rotating a threaded sleeve to control the screw to retract or extend into the threaded sleeve.

[0004] The Chinese patent publication number CN105804417A discloses a support for the installation of prefabricated components of assembled buildings and its use method. The device improves the structure of the telescopic parts so that the telescopic rods have the function of adjusting in three-dimensional space, and two telescopic rods are provided, so that the force is effectively decomposed, the pressure is concentrated on the bolts, the embedded parts are sheared, and excessive pulling of the embedded parts is avoided.

[0005] However, the bidirectional reverse-thread inclined support structure widely used in the current construction field has fundamental mechanical defects: its threaded force transmission path causes the load to be concentrated on the threaded meshing surface, triggering stress concentration and the risk of material fatigue fracture, and single-point failure will cause the overall bearing capacity to collapse. Although the industry has tried to alleviate the load pressure by increasing the number of supports, this solution only achieves planar load dispersion and fails to break through the structural shackles of threaded force transmission. Instead, it has led to secondary problems such as a 30% to 50% surge in construction costs and a decrease in building space utilization. It is urgent to develop a new force transmission mechanism to replace the traditional thread-dependent structural system. Summary of the Invention

[0009] Furthermore, the adjustment support structure also includes a transmission assembly provided in the movable base, and the transmission assembly includes: a worm, which is rotatably installed inside the movable base, and the worm is perpendicular to the plane where the prefabricated plate is located; a rotating shaft, which is rotatably installed inside the movable base, and the rotating shaft is parallel to the plane where the prefabricated plate is located; a worm wheel, which is installed on the rotating shaft, and the worm wheel is engaged with the worm, and a gear is installed on the outside of the rotating shaft below the worm wheel; a rack, which is provided in the bottom structure, and the rack is perpendicular to the plane where the prefabricated plate is located, and the rack is engaged with the gear to enable the movable base to move on the bottom structure.

[0010] Furthermore, the bottom structure includes: a fixed plate, which is fixed to the bottom plate and hinged to the first support arm; a guide frame, which is fixed to one end of the fixed plate close to the prefabricated plate and slidingly connected to the movable seat, and the rack is fixed to the axial direction of the guide frame.

[0011] Furthermore, the guide frame is an "I"-shaped structure, and the width of the upper surface of the guide frame is smaller than the width of its lower surface, so that the gap between the upper and lower surfaces of the guide frame forms a second guide groove; a slot is opened at the lower end of the middle part of the movable seat, and the slot is an inverted "convex"-shaped structure, so that the lower end of the movable seat forms a sliding connection with the guide frame.

[0012] Furthermore, mounting grooves are provided on both sides of the slot on the inner side of the movable seat, and the opposite surfaces of the two mounting grooves are open for accommodating gears.

[0013] Furthermore, first guide grooves adapted to the lifting slide are provided on both sides of the contact plate, an upper connecting buckle is installed on the outer side of the contact plate near the upper end, and a lower connecting buckle is installed on the outer side of the contact plate near the lower end, the upper connecting buckle and the lower connecting buckle are adapted to the embedded bolts, and sliders slidably connected to the first guide grooves are installed on the inner sides of the upper connecting buckle and the lower connecting buckle.

[0014] Furthermore, a connector is installed between two adjacent contact plates, and the connector consists of two groups of square sleeves and a connecting rod located between the two groups of square sleeves.

[0017] The present invention has the following beneficial effects:

[0018] (1) The side support device for installing prefabricated wall panels is formed into a parallelogram with variable height by a first support arm, a second support arm, and a first connecting rod. The support projection length is changed by adjusting the lifting slide of the second connecting rod to achieve adjustment when supporting the prefabricated panel. The traditional threaded force transmission method is improved to a four-bar linkage through a parallelogram mechanism, which evenly distributes the load to the hinge node and avoids the problem of stress concentration on the traditional threaded meshing surface.

[0019] (2) The side support device for installing prefabricated wall panels forms a first triangular structure through a contact plate, a second support arm, and a first connecting rod. The first triangular structure (acute angle / obtuse angle) is used to dynamically adapt to different wall panel sizes, change the support point position, effectively reduce the support point stress caused by the lever effect, and improve the support stability.

[0020] (3) The side support device for installing the prefabricated wall panel forms a force-saving lever with the embedded part as the fulcrum through the fixed plate and the guide frame. The farther the movable seat is from the embedded part, the longer the lever arm is, and the higher the stability of the fixed plate is. When the support point is higher (obtuse angle structure), the lever arm is shortened, but the overall stability can still be maintained through the compensation of the side support force. The side support decomposes the horizontal force F into the component force F2 along the support direction, and F2 is further decomposed into the vertical component force F21 and the horizontal component force F22, balancing the load through the lever effect.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0035] See also Figures 1-10 , an embodiment of the present invention provides a technical solution: a side support device for installing prefabricated wall panels, including a bottom structure and a contact plate 4, the bottom structure is fixedly connected to the embedded parts on the bottom plate 1, it should be noted that the bottom plate 1 needs to be installed with embedded parts during casting, after the bottom plate 1 is formed, the embedded parts are fixed to the bottom plate 1, thereby serving as the support and fixation of the bottom structure, the contact plate 4 is fixedly connected to the embedded bolts 3 on the prefabricated plate 2, and preferably a buffer pad is provided on the side of the contact plate 4 facing the prefabricated plate 2.

[0036] The side support device for installing prefabricated wall panels provided in this embodiment also includes a first support arm 11, a second support arm 12 and a first connecting rod 13, wherein one end of the first support arm 11 is hinged to the end of the bottom structure away from the prefabricated panel 2, and one end of the second support arm 12 is hinged to the upper end of the contact plate 4. There are two groups of first connecting rods 13, and the two ends of the two groups of first connecting rods 13 are hinged to the first support arm 11 and the first connecting rod 13 respectively, so that the first support arm 11, the second support arm 12 and the first connecting rod 13 form a parallelogram. At this time, the enclosed parallelogram is in an unstable state, and its height is variable. By changing the height of the parallelogram, the first support arm 11 and the second support arm 12 are made closer to or farther away from each other.

[0037] In order to achieve the height change of the parallelogram in this solution, the side support device for installing the prefabricated wall panel provided in this embodiment also includes a second connecting rod 14, one end of the second connecting rod 14 is hinged to a corner point of the parallelogram, and preferably a through groove 18 is opened in the middle to prevent the second connecting rod 14 from interfering with the four sides of the parallelogram. In this solution, the second connecting rod 14 is preferably hinged to a corner point of the lower end of the parallelogram close to the prefabricated panel 2. It should be noted that the hinge of the four corner points of the parallelogram will not interfere with the hinge of the second connecting rod 14 and the corner point of the parallelogram. The two hinge modes here are set independently of each other, and the other end of the second connecting rod 14 is rotatably installed with a lifting slide 17, which can slide vertically along the contact plate 4, thereby changing the angle between the second connecting rod 14 and the contact plate 4, further making the second connecting rod 14 The other end of the connecting rod 14 can push the parallelogram to deform so as to adjust the height of the parallelogram. The change in the height of the parallelogram represents the change in the projection length of the first support arm 11 on the second support arm 12, thereby realizing the adjustment of the distance between the first support arm 11 and the second support arm 12. It should be noted that the hinge point between the second connecting rod 14 and the corner point of the parallelogram is used as the center of the circle, and the second connecting rod 14 is used as the radius to make the movement arc of the second connecting rod 14 when the center of the circle is the fixed point. At this time, there will be two intersections between the movement arc and the lifting path of the lifting slide 17. The upper intersection will make the first triangular structure formed between the contact plate 4, the second connecting rod 14 and the second support arm 12 an obtuse triangle, and the lower intersection will make the first triangular structure formed between the contact plate 4, the second connecting rod 14 and the second support arm 12 an acute structure.

[0038] In this solution, the first triangular structure can improve the stability of the prefabricated board 2 when supporting, such as Figure 3 As shown, when the first triangular structure is an acute angle, the lifting slide 17 moves toward the lower end of the contact plate 4, achieving two-point support at the upper and lower ends of the contact plate 4, which can be used to support conventional wall panels; Figure 4As shown, when the first triangular structure is an obtuse angle, the lifting slide 17 moves toward the upper end of the contact plate 4, and the support point is higher, which can achieve support for a higher wall panel.

[0039] To further explain, the common height / length specifications of prefabricated panels 2 are 3000mm, 3300mm, 3600mm, 3900mm and 4200mm. In special cases, there are also lengths of 3800mm and 4000mm, but the longest length of ordinary prefabricated wall panels is 4200mm‌. In this solution, prefabricated panels 2 with a length or height exceeding 3900mm can be regarded as super-high wall panels. After the prefabricated panels 2 are installed, the connection ability between their lower ends and the base plate 1 is poor. After being subjected to external forces, the prefabricated panels 2 are equivalent to a labor-saving lever with the joint as the fulcrum. At the same height of the support point, the higher the prefabricated panel 2, the worse the support effect. To improve the support strength of the prefabricated panel 2, it is necessary to increase the height of the support point. In this solution, the height of the support point is adjusted by changing the height of the lifting slide 17, so that higher prefabricated panels 2 can be supported. Due to the stability of the first triangular structure, the support effect is greatly improved.

[0040] In addition, the side support device for installing prefabricated wall panels provided in this embodiment also includes an adjustable support structure, which is installed on the bottom structure and is used to adjust the height of the lifting slide 17 on the contact plate 4.

[0041] like Figures 1-4 As shown, the adjustable support structure provided in this embodiment includes a movable seat 9 and a side support 10. The movable seat 9 is arranged on the bottom structure, and the movable seat 9 is slidably connected to the bottom structure to adjust the vertical distance from the movable seat 9 to the prefabricated panel 2; there are two groups of side supports 10, one end of the two groups of side supports 10 is respectively hinged to the two sides of the movable seat 9, and the other end of the side support 10 is hinged to the lifting slide 17, so that the bottom plate 1, the side support 10 and the prefabricated panel 2 form a second triangular structure, and then realize the support of the lifting slide 17, thereby improving the support stability of the lower end of the resistance plate 4, and further improving the stability of the support process of the prefabricated panel 2.

[0042] like Figure 9 and Figure 10 As shown, the adjustment support structure provided in this embodiment also includes a transmission assembly arranged in the movable seat 9, and the transmission assembly includes a worm 29, which is rotatably installed inside the movable seat 9, and the worm 29 is perpendicular to the plane where the prefabricated plate 2 is located. Preferably, a transmission cavity 28 is provided at the upper end of the movable seat 9 for installing the worm 29, and a rocker 30 can be installed at the driving end of the worm 29 to drive the worm 29 to rotate.

[0043] The transmission assembly provided in this embodiment also includes a rotating shaft 31, which is rotatably installed inside the moving base 9, and the rotating shaft 31 is parallel to the plane where the prefabricated plate 2 is located. A worm gear 32 is installed on the rotating shaft 31, and the worm gear 32 meshes with the worm 29. A gear 33 is installed on the outer side of the rotating shaft 31 below the worm gear 32, and a rack 27 is provided in the bottom structure, and the rack 27 is perpendicular to the plane where the prefabricated plate 2 is located. In this scheme, the worm 29 is driven to rotate by the rocker 30, and the worm 29 meshes with the worm gear 32, so that the worm gear 32 drives the rotating shaft 31 to rotate, further causing the gear 33 to rotate, and the rack 27 meshes with the gear 33, so that the moving base 9 moves on the bottom structure. Since the worm gear 32 has self-locking ability when meshing with the worm 29, the moving base 9 will not rotate the gear 33 under the thrust of the lower end of the side support 10, thereby ensuring the stability of the position of the moving base 9 and improving the overall structural stability of the equipment.

[0044] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 9 As shown, the bottom structure provided in this embodiment includes a fixing plate 7, which is fixed on the base plate 1 and fixedly connected to the embedded parts on the base plate 1, and one end of the fixing plate 7 close to the embedded parts is hinged to the first support arm 11.

[0045] The bottom structure provided in this embodiment also includes a guide frame 8, which is fixed to one end of the fixed plate 7 close to the prefabricated plate 2, and the guide frame 8 is slidingly connected to the movable seat 9. The rack 27 is fixed to the axial direction of the guide frame 8, and the rack 27 is engaged with the gear 33 to make the movable seat 9 move on the guide frame 8 to adjust the distance between the movable seat 9 and the prefabricated plate 2.

[0046] In this solution, since the fixed plate 7 is fixedly connected to the embedded parts on the base plate 1, the fixed plate 7 and the guide frame 8 form a labor-saving lever structure with the embedded parts as the fulcrum. During this process, the lifting slide 17 will be subjected to the horizontal force F. By decomposing F, we obtain a component force F2 in the direction of the side support 10. F2 acts directly on the moving seat 9. Then, by decomposing F2, we obtain a horizontal component force F22 and a vertical component force F21. F21 acts on the labor-saving lever. Since the farther the moving seat 9 is from the embedded parts, the longer the lever arm, the better the stability of the fixed plate 7. This just corresponds to the situation that when the first triangular structure is an obtuse angle, the distance between the lower end of the side support 10 and the prefabricated plate 2 is shorter. At this time, the stability of the lower end of the side support 10 is better. The stability of the fixed plate 7 is poor, and as the lever arm increases, the stability of the fixed plate 7 is improved, thereby compensating for the overall stability of the equipment, so that the equipment can also provide good support effects when facing higher prefabricated panels 2. When the first triangular structure is an acute angle, although the stability of the fixed plate 7 decreases in comparison, it still forms a labor-saving lever structure with the embedded parts as the fulcrum with the guide frame 8, F21 increases, so that the fixed plate 7 is still stable, and at this time the moving seat 9 is far away from the prefabricated panel 2, which increases the bottom length of the second triangular structure, and then the component of the force exerted on the lifting slide 17 on the side support 10 will increase, so that the force of the moving seat 9 on the fixed plate 7 increases, so as to compensate for the reduction of the lever arm of the labor-saving lever structure and still make the equipment stable.

[0047] like Figure 9 and Figure 10 As shown, in order to satisfy the requirement that the moving seat 9 can move on the guide frame 8 without separating from the guide frame 8, the guide frame 8 provided in this embodiment is an "I"-shaped structure, and the width of the upper surface of the guide frame 8 is smaller than the width of its lower surface, so that the gap between the upper and lower surfaces of the guide frame 8 forms a second guide groove 26, and a notch 35 is provided at the lower end of the middle part of the moving seat 9. The notch 35 is an inverted "convex"-shaped structure, so that the lower end of the moving seat 9 forms a sliding connection with the guide frame 8, and the notch 35 cooperates with the second guide groove 26 to restrict the moving seat 9 on the guide frame 8 to prevent the moving seat 9 from separating from the guide frame 8 after being subjected to force.

[0048] like Figure 9 and Figure 10 As shown, the movable seat 9 provided in this embodiment has mounting grooves 34 on both sides of the notch 35 , and the opposite surfaces of the two mounting grooves 34 are open to accommodate the gear 33 , thereby realizing transmission between the gear 33 and the rack 27 .

[0049] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, the first guide grooves 19 adapted to the lifting slide 17 are opened on both sides of the contact plate 4 provided in this embodiment, and an upper connecting buckle 5 is installed near the upper end position of the outer side of the contact plate 4, and a lower connecting buckle 6 is installed near the lower end position of the outer side of the contact plate 4. The upper connecting buckle 5 and the lower connecting buckle 6 are adapted to the embedded bolt 3. Preferably, the upper connecting buckle 5 and the lower connecting buckle 6 are both bow-shaped structures, and connecting through holes are provided at both ends. The connecting through holes are flat structures and are used to adjust the connection position of the embedded bolt 3 and the upper connecting buckle 5 and the lower connecting buckle 6 on the vertical plane to improve the fault tolerance of the equipment. After the embedded bolt 3 is inserted into the connecting through hole, the gasket and the nut are installed in sequence to realize the upper connecting buckle 5 and the lower connecting buckle 6. The connecting buckle 6 is fixed. In addition, anti-slip pads are installed on the inner sides of the upper connecting buckle 5 and the lower connecting buckle 6 and the contact plate 4 to increase the stability of the upper connecting buckle 5 and the lower connecting buckle 6 after they are fixed, and improve the stability of the contact plate 4 after installation. A slider 20 is installed on the inner sides of the upper connecting buckle 5 and the lower connecting buckle 6, which is slidably connected to the first guide groove 19. Preferably, the slider 20 is fixed to the inner sides of the upper connecting buckle 5 and the lower connecting buckle 6 by means of clamping, bolts, etc., and the slider 20 cooperates with the first guide groove 19 so that the upper connecting buckle 5 and the lower connecting buckle 6 can slide along the contact plate 4 to adjust the position height of the upper connecting buckle 5 and the lower connecting buckle 6 to make them compatible with the embedded bolts 3.

[0050] like Figure 1 As shown, in order to further improve the stability of the prefabricated panel 2 after installation, a connecting piece is installed between two adjacent contact plates 4. The connecting piece consists of two groups of square sleeves 15 and a connecting rod 16 located between the two groups of square sleeves 15. The two ends of the connecting rod 16 are respectively inserted into the square sleeves 15 and slidably connected to the square sleeves 15 to adjust the distance between the two adjacent contact plates 4. The two adjacent side support devices are connected through the connecting piece, thereby realizing three-dimensional support after the installation of the prefabricated panel 2 and improving the support effect.

[0051] like Figure 5 As shown, in order to realize the connection between the connecting member and the contact plate 4, a plug 22 is provided at one end of the square sleeve 15 close to the contact plate 4, and a second socket 23 is provided on the plug 22. A slot 25 for connecting with the plug 22 is provided at the top of the contact plate 4, and a first socket 21 passing through the slot 25 is provided on the outside of the contact plate 4. A pin 24 for connecting with the second socket 23 is installed inside the first socket 21, thereby realizing the fixation between the square sleeve 15 and the contact plate 4.

[0052] like Figure 1 As shown, the first support arm 11, the second support arm 12, the first connecting rod 13, and the second connecting rod 14 provided in this embodiment are all made of square steel or I-beams. Square steel or I-beams have a strong supporting effect and are not easy to deform, providing a better foundation for the support of the prefabricated panel 2 after installation.

[0053] During use (working), the position of the lifting slide 17 is adjusted according to the specific height of the prefabricated panel 2. When the prefabricated panel 2 is an ultra-high wall panel, the lifting slide 17 needs to be moved to the middle section of the contact plate 4, so that the first triangular structure formed between the second support arm 12, the second connecting rod 14 and the contact plate 4 is an obtuse triangle. When the prefabricated panel 2 is of normal wall panel height, the lifting slide 17 needs to be moved to the lower section of the contact plate 4, so that the first triangular structure formed between the second support arm 12, the second connecting rod 14 and the contact plate 4 is an acute triangle. The second triangular structure is formed by the bottom plate 1, the side support 10 and the prefabricated panel 2, and then the support of the lifting slide 17 is realized, thereby improving the support stability of the lower end of the contact plate 4, and further improving the stability of the support process of the prefabricated panel 2.

[0054] According to the position of the embedded bolts 3, the positions of the upper connecting buckle 5 and the lower connecting buckle 6 are adjusted so that the contact plate 4 is fixed on the prefabricated plate 2, and the fixed plate 7 is fixed by the embedded parts. The rocker 30 is rotated to drive the worm 29 to rotate through the rocker 30, and the worm 29 is engaged with the worm gear 32, so that the worm gear 32 drives the rotating shaft 31 to rotate, and further rotates the gear 33, and the rack 27 is engaged with the gear 33, so that the movable seat 9 moves on the bottom structure, thereby adjusting the position of the movable seat 9, and the side support 10 is driven by the movable seat 9 to move, so as to adjust the angle between the side support 10 and the horizontal plane, and further make the side support 10 drive the lifting slide 17 to move on the contact plate 4, thereby adjusting the distance between the lifting slide 17 and the bottom plate 1 to change the lifting position. The support height of the lowering slide 17. Of course, the height adjustment here can only be used for fine-tuning after the equipment is installed. It is mainly suitable for the situation where the prefabricated panel 2 is tilted. Driven by the lifting slide 17, the second connecting rod 14 is moved, so that the second connecting rod 14 pulls a corner point of the parallelogram structure to change the height of the parallelogram, and then adjusts the longest distance from the first support arm 11 to the second support arm 12 to push the prefabricated panel 2 to move until the prefabricated panel 2 is perpendicular to the base plate 1. In this process, since the worm gear 32 has self-locking ability when meshing with the worm 29, the movable seat 9 will not rotate the gear 33 under the thrust of the lower end of the side support 10, thereby ensuring the stability of the position of the movable seat 9 and improving the overall structural stability of the equipment.
