[0020] First embodiment: See Figure 1 This is a structural schematic diagram of a multifunctional fixing device 100 for storing reinforcing bars 200 provided in an embodiment of this utility model. Combined with... Figures 2-4 Specifically, the multifunctional fixing device 100 includes a support base 110 and an enclosure structure 120 that cooperate with each other; the top surface of the support base 110 is used to place the reinforcing bar 200; the enclosure structure 120 is vertically connected to the opposite edge of the support base 110, and the enclosure structure 120 and the support base 110 cooperate to form a receiving space 113 for storing the reinforcing bar 200; the enclosure structure 120 is provided with a plurality of partitions 130 arranged at intervals along its height direction, and the plurality of partitions 130 with opposite top surfaces at the same height form a support platform for supporting the reinforcing bar 200; wherein, the distance between two adjacent partitions 130 arranged along the height direction is greater than the diameter of the reinforcing bar 200.

[0021] By installing dividers 130 on the enclosure structure 120, the reinforcing bars 200 are placed in layers. Specifically, the support provided by the dividers 130 at different heights effectively prevents the reinforcing bars 200 from piling up. On the one hand, the support base 110 prevents the reinforcing bars 200 from directly contacting the ground and being affected by moisture from the ground. On the other hand, the dividers 130 facilitate the handling of the reinforcing bars 200 from the multi-functional fixing device 100, preventing them from being clustered together and making it difficult to handle them in batches. In other words, by installing dividers 130, the clustered reinforcing bars 200 are separated and stored, improving handling efficiency.

[0022] Preferably, the enclosure structure 120 includes a first vertical rod group and a second vertical rod group; the support base 110 includes a first fixed support 111 and a second fixed support 112 that are detachably coupled to each other; the first vertical rod group is connected to the side of the first fixed support 111 away from the second fixed support 112; the second vertical rod group is connected to the side of the second fixed support 112 away from the first fixed support 111 and is arranged opposite to the first vertical rod group; wherein, a plurality of partitions 130 are arranged in at least one of the first vertical rod group and the second vertical rod group.

[0023] Preferably, the first fixed support 111 further includes, for example, a fixed base plate 1111 and a support structure 1113.

[0024] Specifically, the cooperation between the limiting slide rail 1112 and the first pulley group 1122 improves the efficiency of assembling the support base 110. Furthermore, by adjusting the distance between the first fixed support 111 and the second fixed support 112, that is, by changing the distance between the first vertical rod group and the second vertical rod group, different quantities of steel bars 200 can be stored. When the number of stored steel bars 200 is small, the distance between the first vertical rod group and the second vertical rod group can be adjusted to decrease; conversely, the distance between the first vertical rod group and the second vertical rod group can be adjusted to increase.

[0025] Preferably, the support structure 1113 includes interconnected horizontal plates 1114 and vertical plates 1115; The vertical plate 1115 is connected to the fixed base plate 1111 and is arranged adjacent to the limiting slide rail 1112; The horizontal plate 1114 is connected to the top of the vertical plate 1115 and extends toward the direction of the limiting slide rail 1112 to form a movable structure between it and the fixed base plate 1111, which houses the connecting base plate 1121 and the first pulley group 1122.

[0026] Preferably, the side of the connecting base plate 1121 is provided with a plurality of first limiting through holes 1123 arranged at intervals with each other; The fixed base plate 1111 is provided with a second limiting through hole 1116 for cooperating with a plurality of first limiting through holes 1123; When the limiting member passes through any one of the multiple first limiting through holes 1123 and any one of the multiple second limiting through holes 1116 in sequence, the first pulley group 1122 is restricted from reciprocating on the limiting slide rail 1112. Among them, multiple first limiting through holes 1123 and multiple second limiting through holes 1116 are respectively arranged at intervals along the first direction.

[0027] Specifically, by sequentially inserting the limiting member into the first limiting through hole 1123 and the second limiting through hole 1116, the first fixed support 111 and the second fixed support 112 are effectively fixed relative to each other, ensuring the structural stability of the multifunctional fixing device 100.

[0028] and / or The first pulley block 1122 is equipped with brake pads.

[0029] Preferably, the fixed base plate 1111 is provided with a guide ramp 1117 at the edge position corresponding to the limiting slide rail 1112; wherein, the moving structure enters the limiting slide rail 1112 by cooperating with the guide ramp 1117. By setting the guide ramp 1117, the difficulty of pushing the first slide rail group into the limiting slide rail 1112 is reduced, and the efficiency of assembling the support base 110 is improved.

[0030] Preferably, any partition 130 includes a nested ring 131 and a support rod 132; the nested ring 131 is connected to the enclosure structure 120 and is used to pass through the support rod 132.

[0031] Preferably, either the first vertical rod group or the second vertical rod group is composed of a plurality of vertical support rods 132 arranged at intervals; at least one side of any vertical support rod 132 is provided with a plurality of partitions 130 arranged at intervals along its height direction; wherein, the support rod 132 provided in either the first vertical rod group or the second vertical rod group extends toward the other.

Specifically, the water-permeable perforated structure can prevent water accumulation and avoid water contact with the reinforcing bar 200 placed above it.

[0034] Second embodiment: See Figure 5 This is a structural schematic diagram of a multifunctional fixing device 100 for storing steel bars 200 provided in an embodiment of this utility model, combined with... Figure 1 , Figures 6-9Specifically, the multifunctional fixing device 100 includes a support base 110 and an enclosure structure 120 that cooperate with each other; the top surface of the support base 110 is used to place the reinforcing bar 200; the enclosure structure 120 is vertically connected to the opposite edge of the support base 110, and the enclosure structure 120 and the support base 110 cooperate to form a receiving space 113 for storing the reinforcing bar 200; the enclosure structure 120 is provided with a plurality of partitions 130 arranged at intervals along its height direction, and the plurality of partitions 130 with opposite top surfaces at the same height form a support platform for supporting the reinforcing bar 200; wherein, the distance between two adjacent partitions 130 arranged along the height direction is greater than the diameter of the reinforcing bar 200.

[0035] Preferably, the enclosure structure 120 includes multiple nested first L-shaped rods 1 and multiple second L-shaped rods 2; a horizontal plate 4 is fixedly connected between two adjacent first L-shaped rods 1, and a fixing plate 5 is fixedly connected to one side of the horizontal plate 4, extending towards the second L-shaped rod 2; the outer walls of the multiple second L-shaped rods 2 away from the first L-shaped rods 1 are fixedly connected by a pull plate 6, and a threaded rod 7 is threaded onto the pull plate 6; wherein the threaded rod 7 engages with any of the multiple screw holes on the fixing plate 5 located below it to adjust the spacing between the multiple first L-shaped rods 1 and the multiple second L-shaped rods 2. Through the engagement between the first L-shaped rods 1 and the second L-shaped rods 2, the steel reinforcement 200 is prevented from directly contacting the ground and rusting due to moisture when stored, thereby improving the performance of the steel reinforcement 200 and enhancing construction safety.

[0036] For example, at least one separator 130 connects a first L-shaped rod 1 and a second L-shaped rod 2 opposite to it. Specifically, when there are multiple separators 130, they are spaced apart along the height direction of the first L-shaped rod 1 and the second L-shaped rod 2 to store and support the reinforcing bars 200 at different heights, thus separating the reinforcing bars 200 and preventing them from piling up. Furthermore, when it is necessary to move the reinforcing bars 200, a large number of reinforcing bars 200 are tightly packed together, making it difficult to move them effectively using tools. However, by combining the technical solution of this utility model embodiment, the reinforcing bars 200 are separated and placed separately. The spacing between the separators 130 formed at different heights enables effective handling of the reinforcing bars 200, while avoiding the problem of rainwater accumulating on the surface of the multifunctional fixing device 100 when it is placed outdoors due to the reinforcing bars 200 being tightly packed together.

[0037] Preferably, a side plate 3 is fixedly connected to one side of both the first L-shaped rod 1 and the second L-shaped rod 2, and a first bolt 301 is threaded onto the side plate 3. A U-shaped groove is opened at the top of both the first L-shaped rod 1 and the second L-shaped rod 2, and a fixing rod 304 is fixedly connected inside the U-shaped groove. A telescopic plate 302 is rotatably connected to the outer wall of the fixing rod 304, and a square flange 303 is fixedly connected to the end of the telescopic plate 302 away from the fixing rod 304. A telescopic spring 101 is fixedly connected to the inner wall of the first L-shaped rod 1, and a crossbar 102 is fixedly connected to the inner side wall of the first L-shaped rod 1. The crossbar 102 is located on both sides of the telescopic spring 101, and sliding blocks 103 are fixedly connected to both sides of the second L-shaped rod 2.

[0038] Specifically, threaded holes are provided on both the side plate 3 and the telescopic plate 302, with two threaded holes corresponding to each other. The first bolt 301 fixes the telescopic plate 302 to the side plate 3 through the threaded holes. The two square flanges 303 are fixed by bolted rods 7. One end of the telescopic spring 101 is connected to the inner wall of the first L-shaped rod 1, and the other end of the telescopic spring 101 is connected to the second L-shaped rod 2. The telescopic spring 101 can not only adjust the distance between the first L-shaped rod 1 and the second L-shaped rod 2, but also clamp the two sides of the reinforcing bar 200, improving the safety of the reinforcing bar 200. A crossbar 102 is fixedly connected to the inner wall of the first L-shaped rod 1, and the crossbar 102 is located on both sides of the telescopic spring 101. Sliding blocks 103 are fixedly connected to both sides of the L-shaped rod 2. The sliding blocks 103 have sliding openings and are slidably connected to the crossbar 102 through the sliding openings. By pulling the pull plate 6, the second L-shaped rod 2 slides outward according to the action of the telescopic spring 101, thereby increasing the distance between the first L-shaped rod 1 and the second L-shaped rod 2. Then, the steel bar 200 is fixed on top by the action of the two telescopic plates 302 and the square flange 303. This setting increases the usable area for storing the steel bar 200. The cooperation between the telescopic plates 302 and the square flange 303 increases the stability of the steel bar 200 and reduces the danger to construction workers caused by the storage of the steel bar 200.

[0039] The functional principle of this utility model can be explained through the following operation: Before placing the reinforcing bar 200, the two square flanges 303 are disassembled using the bolt rod 7. Then, the two telescopic plates 302 are lifted, and the side plate 3 is fixed to the telescopic plate 302 using the first bolt 301. Then, the distance between the first L-shaped rod 1 and the second L-shaped rod 2 is adjusted according to the number of reinforcing bars 200. The pull plate 6 is pulled, causing the second L-shaped rod 2 to slide outward under the action of the telescopic spring 101, thereby increasing the distance between the first L-shaped rod 1 and the second L-shaped rod 2. When the distance between the first L-shaped rod 1 and the second L-shaped rod 2 is adjusted, the fixing plate 5 and the pull plate 6 are fixed using the bolt rod 7. At this time, the reinforcing bar 200 can be placed. The steel bar 200 is stored on top of the first L-shaped rod 1 and the second L-shaped rod 2. After the steel bar 200 is stored, the first bolt 301 is removed. Then, using the telescopic effect of the telescopic plate 302 (this is existing technology and will not be described in detail), the two square flanges 303 are brought into contact and then fixed by the bolt rod 7. It should be noted that this setting avoids the steel bar 200 from directly contacting the ground and rusting due to moisture, thereby improving the use effect of the steel bar 200, improving construction safety, and increasing the usable area for storing the steel bar 200. The cooperation between the telescopic plate 302 and the square flanges 303 increases the stability of the steel bar 200 storage and reduces the danger to construction personnel caused by the storage of the steel bar 200.

[0040] Although the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
