Description

Technical Field

[0001] This invention relates to the field of building auxiliary support frame technology, specifically to an auxiliary support device for the installation of prefabricated balconies. Background Technology

[0002] The support system for prefabricated balcony installation generally adopts a traditional scaffolding steel pipe frame system. The spacing between the uprights is 0.6 meters, 0.8 meters, and 1.2 meters. There are no fewer than three horizontal tie rods. The uprights and horizontal rods are connected by bolts and fasteners or disc buckles and pins. An adjustable threaded T-shaped top support is installed at the top of the uprights. Wooden blocks or sleepers are placed on the top support. The elevation and flatness of the prefabricated balcony installation are adjusted by the adjustable threaded T-shaped top support.

[0003] Existing auxiliary support equipment is cumbersome to install, requiring splicing and fixing during use. This makes it difficult to adjust the support area after installation, necessitating continuous adjustments. Furthermore, when the upper part of the auxiliary support equipment supports and fixes the precast balcony, it cannot restrict the edge of the precast balcony, making it prone to displacement on the auxiliary support equipment. To address these issues, we propose an auxiliary support equipment for precast balcony installation. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary support device for the installation of prefabricated balconies, in order to solve the problems mentioned in the background art. The existing auxiliary support devices are cumbersome to install, require splicing and fixing during use, and are not easy to adjust after installation. This makes it necessary to constantly adjust the support area after splicing and installation. Furthermore, when the upper part of the auxiliary support device supports and fixes the prefabricated balcony, it cannot restrict the edge of the prefabricated balcony, making the prefabricated balcony prone to positional displacement on the auxiliary support device.

Each of the four sets of sliding sleeves has a support rod hinged to one of its opposite sides. The opposite end of each of the four sets of support rods is connected to the opposite column. The four sets of support rods are arranged in parallel and intersecting directions. The six sets of columns are symmetrically divided into two groups, and a first hinge rod and a second hinge rod are hinged between the two groups of columns. The first hinge rod and the second hinge rod are rotatably connected.

[0011] Preferably, the expansion assembly includes two sets of first top plates, two sets of second hinge rods movably mounted on the upper ends of four sets of columns at the left and right ends, two sets of screws fixedly mounted on opposite sides of the two sets of first top plates, and a second top plate movably mounted on opposite sides of the four sets of screws.

Multiple sets of movable slots are provided in the first top plates below the two sets of storage slots. Springs are installed in the multiple sets of movable slots. A stop block is movably installed in the upper opening of the multiple sets of movable slots. The lower end of the stop block abuts against the upper end of the spring. Limiting plates are rotatably installed on opposite sides of the two sets of first top plates.

[0013] Preferably, the limiting plate is L-shaped and the limiting plate is V-shaped and installed on the first top plate, with the lower side of the opposite end of the two sets of limiting plates abutting the upper end of the abutment block.

[0014] Preferably, the fixing assembly includes two sets of first base plates, which are movably installed on the lower sides of four sets of columns at the left and right ends of the six sets of columns. Clamping plates are movably installed on the lower sides of the two sets of first base plates. A second threaded groove is provided in both sets of first base plates and the two sets of clamping plates. A second bolt is inserted into the second threaded groove by thread. A second base plate is movably installed on the lower sides of the two sets of columns at the center position of the six sets of columns.

[0019] When the prefabricated balcony is placed on the extension component, the prefabricated balcony presses down on the limiting components at both ends of the extension component, causing the limiting components to rotate and squeeze and limit the left and right sides of the prefabricated balcony, thus preventing the prefabricated balcony from shifting after it is placed on the extension component.

[0020] By fixing the lower ends of the six sets of columns to the edge of the prefabricated balcony on the next floor with fixing components, the six sets of columns can remain parallel to the position of the prefabricated balcony to be installed during installation, and prevent the six sets of columns from moving during the installation of the prefabricated balcony.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Please see Figure 1-6 The present invention provides an embodiment of an auxiliary support device for the installation of a prefabricated balcony, comprising six sets of columns 1 for supporting the prefabricated balcony;

[0031] The storage components are hinged to the six sets of columns 1. The storage components on the four sets of columns 1 at the left and right ends of the six sets of columns 1 are cross-installed. The storage components are used to provide quick unfolding and fixing when the six sets of columns 1 support the installation of the prefabricated balcony.

[0032] The expansion component is installed on the upper end of the six sets of columns 1. The expansion component is detachably connected to the six sets of columns 1. The expansion component is used to adapt to the installation of the six sets of columns 1 when they are unfolded into different sizes.

[0033] Limiting components are set on the upper left and right ends of the extension components. The limiting components are rotatably connected to the extension components. The limiting components are used to limit the position of the prefabricated balcony on the left and right sides when the prefabricated balcony is placed on the extension components.

[0034] The fixing component is installed on the lower end of the six sets of columns 1. The fixing component is fixedly connected to the prefabricated balcony on the next floor. The fixing component is used to fix the lower end of the six sets of columns 1 to prevent displacement when supporting the prefabricated balcony. This device controls the size of the six sets of columns 1 when unfolded by the storage component, and facilitates the unfolding and installation of the six sets of columns 1 in different positions, thereby improving the installation speed of the six sets of columns 1. Then, the expansion component is unfolded and adapted to the six sets of columns 1 for installation, which increases the overall support effect of the prefabricated balcony. The limiting component limits and fixes the left and right sides when the prefabricated balcony is placed on the expansion component. When the six sets of columns 1 are unfolded, they are connected and fixed to the prefabricated balcony on the next floor through the fixing component, so as to keep the prefabricated balcony fixed during the auxiliary installation of the prefabricated balcony.

[0035] Furthermore, the storage assembly includes four sets of sliding sleeves 2, which are movably installed on the four sets of columns 1 at the left and right ends of the six sets of columns 1. Each of the four sets of sliding sleeves 2 has a support rod 3 hinged to one of its opposite sides. The opposite ends of the four support rods 3 connected to the sliding sleeves 2 are connected to the opposite columns 1. The four support rods 3 are arranged in parallel and crosswise configurations. The six sets of columns 1 are symmetrically divided into two groups, and a first hinge rod 4 and a second hinge rod 5 are hinged between the two groups of columns 1. The first hinge rod 4 and the second hinge rod 5 are rotatably connected. This structure allows the six sets of columns 1 to be unfolded back and forth through the crosswise support rods 3, and then the six sets of columns 1 to be unfolded left and right through the first hinge rod 4 and the second hinge rod 5. This allows the six sets of columns 1 to be unfolded and installed on the construction site.

[0036] Furthermore, the expansion assembly includes two sets of first top plates 6, two sets of second hinge rods 5 movably installed on the upper ends of four sets of columns 1 at the left and right ends, two sets of screw rods 7 fixedly installed on opposite sides of the two sets of first top plates 6, and a second top plate 8 movably installed on opposite sides of the four sets of screw rods 7. Four sets of grooves 9 are symmetrically opened in the second top plate 8, and the four sets of screw rods 7 are movably inserted into the grooves 9. Four sets of screws 10 are rotatably installed at the openings of the four sets of grooves 9. The four sets of screws 10 are threaded onto the four sets of screw rods 7. By twisting the four sets of screws 10, the four sets of screw rods 7 slide out from the second top plate 8. The four sets of screw rods 7 drive the two sets of first top plates 6 to unfold to the left and right ends, so that the expansion assembly can be unfolded and connected with the six sets of columns 1 for installation, thereby providing auxiliary support during the installation of the prefabricated balcony.

[0037] Furthermore, the limiting component includes two sets of storage slots 15, which are symmetrically opened in the two sets of first top plates 6. Multiple sets of movable slots 16 are opened in the first top plates 6 below the two sets of storage slots 15. Springs 17 are installed in the multiple sets of movable slots 16. A stop block 18 is movably installed in the upper opening of the multiple sets of movable slots 16. The lower end of the stop block 18 abuts against the upper end of the spring 17. Limiting plates 19 are rotatably installed on opposite sides of the two sets of first top plates 6. When the prefabricated balcony is placed on the two sets of first top plates 6 and second top plates 8, the limiting plates 19 at the left and right ends of the two sets of first top plates 6 limit the left and right sides of the prefabricated balcony, so that the prefabricated balcony will not slide or shift to the left and right sides after being placed on the two sets of first top plates 6 and second top plates 8, thereby improving the limiting effect of the prefabricated balcony installation.

[0038] Furthermore, the limiting plate 19 is L-shaped and V-shaped, installed on the first top plate 6. The lower side of the opposite end of the two sets of limiting plates 19 abuts against the upper end of the abutment block 18. According to the shape and installation method of the limiting plate 19, when the prefabricated balcony is placed on the two sets of first top plates 6 and second top plates 8, the prefabricated balcony squeezes the two sets of limiting plates 19 on the ends of the two sets of first top plates 6, squeezing the ends of the two sets of limiting plates 19 installed in the first top plates 6 into the storage groove 15, thereby limiting the other ends of the two sets of limiting plates 19 to the left and right ends of the prefabricated balcony.

[0039] Furthermore, the fixing assembly includes two sets of first base plates 20, which are movably installed on the lower sides of four sets of columns 1 at both ends of the six sets of columns 1. Clamping plates 21 are movably installed on the lower sides of the two sets of first base plates 20. Second threaded grooves 22 are opened in both sets of first base plates 20 and two sets of clamping plates 21. Second bolts 23 are inserted into the second threaded grooves 22 by threads. Second base plates 24 are movably installed on the lower sides of the two sets of columns 1 in the center position of the six sets of columns 1. This structure can fix the two sets of clamping plates 21 to the upper edge of the prefabricated balcony of the next layer by twisting the four sets of second bolts 23. Thus, the two sets of first base plates 20 and clamping plates 21 are clamped and fixedly installed on the edge of the prefabricated balcony of the next layer, thereby fixing the six sets of columns 1.

[0040] Furthermore, the two sets of clamping plates 21 are L-shaped, and the inner right side of the two sets of clamping plates 21 is flush with the left and right sides of the six sets of columns 1. The lower sides of the two sets of first base plates 20 and the lower sides of the second base plates 24 are on the same plane. Based on the shape of the two sets of clamping plates 21 and the lower plane position of the two sets of first base plates 20 and second base plates 24, this structure ensures that when the two sets of first base plates 20 and second base plates 24 are attached to the prefabricated balcony on the next floor, the support height of the six sets of columns 1 can be kept consistent.

[0041] Furthermore, two sets of slots 11 are provided on the lower sides of the two sets of first top plates 6 and second top plates 8 and on the upper sides of the two sets of first bottom plates 20 and second bottom plates 24. Insert blocks 12 are welded and installed on the upper and lower ends of the six sets of columns 1. The six sets of insert blocks 12 are movably inserted into the six sets of slots 11. First threaded grooves 13 are provided on the two sets of first top plates 6, second top plates 8, two sets of first bottom plates 20, and second bottom plates 24 and in the insert blocks 12. First bolts 14 are movably inserted into the first threaded grooves 13. This structure inserts the insert blocks 12 on the upper and lower sides of the six sets of columns 1 into the slots 11 on the first top plates 6, second top plates 8, two sets of first bottom plates 20, and second bottom plates 24, and fixes them by inserting the first bolts 14 into the first threaded grooves 13, so that the two sets of first top plates 6, second top plates 8, two sets of first bottom plates 20, and second bottom plates 24 are fixedly connected to the six sets of columns 1.

[0042] Furthermore, both sets of first roof slabs 6 and second roof slabs 8 have wavy patterns on their upper surfaces. The wavy patterns on the upper surfaces of the two sets of first roof slabs 6 and second roof slabs 8 are three millimeters thick. This structure, based on the patterns on the upper surfaces of the two sets of first roof slabs 6 and second roof slabs 8, increases the friction between the two sets of first roof slabs 6 and second roof slabs 8 when the prefabricated balcony is placed on them. Moreover, based on the thickness of the patterns, the durability of the patterns on the upper surfaces of the two sets of first roof slabs 6 and second roof slabs 8 is increased.

[0043] Working principle: When providing auxiliary support for prefabricated balconies, such as... Figure 2 and Figure 3 As shown, first, pull the two sets of columns 1 forward and backward in groups of three to unfold. The unfolding of the six sets of columns 1 causes the four sets of support rods 3 to rotate and unfold. Furthermore, the four sets of sliding sleeves 2 connected to the four sets of support rods 3 slide and unfold on the four sets of columns 1. After unfolding the four sets of support rods 3 and the six sets of columns 1 forward and backward, unfold the six sets of columns 1 to the left and right. When the six sets of columns 1 unfold, they cause the first hinge rod 4 and the second hinge rod 5 connected to the six sets of columns 1 to unfold, thus allowing the six sets of columns 1 to be used. After unfolding the six sets of columns 1, as shown... Figure 5 and Figure 6As shown, firstly, the two sets of first top plates 6 and second top plates 8 are fitted onto the inserts 12 at the upper end of the six sets of columns 1 through slots 11. Then, the first bolts 14 are inserted into the first threaded grooves 13 to fix the six sets of columns 1 to the two sets of first top plates 6 and second top plates 8. When connecting the two sets of first top plates 6 and second top plates 8 to the six sets of columns 1, turning the four sets of screws 10 causes the four sets of screw rods 7 to slide out from the four sets of grooves 9. The sliding out of the four sets of screw rods 7 causes the two sets of first top plates 6 to move and unfold to the left and right ends, so that the two sets of first top plates 6 and second top plates 8 are adapted to the unfolded size of the six sets of columns 1. Then, the two sets of first bottom plates 20 and second bottom plates 24 are fitted onto the inserts 12 at the upper end of the six sets of columns 1 through slots 11. The first bolts 14 are inserted into the first threaded grooves 13 to fix the two sets of first bottom plates 20 and second bottom plates 24 to the six sets of columns 1. After fixing the connection, twist the four sets of second bolts 23 to move the two sets of clamping plates 21 downwards, clamping the lower side of the first base plate 20 and the upper side of the clamping plates 21 onto the edge of the prefabricated balcony, thus fixing the six sets of columns 1. When assisting in the installation of the prefabricated balcony, when the prefabricated balcony is placed on the two sets of first top plates 6 and second top plates 8, the left and right ends of the prefabricated balcony are squeezed against the two sets of limiting plates 19. The two sets of limiting plates 19 are squeezed and flipped into the storage groove 15, and the opposite ends of the two sets of limiting plates 19 are clamped with the edge of the prefabricated balcony. When the two sets of limiting plates 19 are stationary, the spring 17 in the movable groove 16 pushes out the abutment block 18, so that the abutment block 18 abuts against the limiting plates 19, preventing the two sets of limiting plates 19 from flipping into the storage groove 15 when stationary. The above is the entire working principle of the present invention.
