Description

Technical Field

[0001] The invention relates to the technical field of steel bar shed installation, in particular to an assembled temporary steel bar shed. Background Art

[0002] The steel bar shed is a protective structure at the construction site, which is used to protect the processing site of steel bar materials. Traditional steel bar sheds usually use steel pipes as the supporting frame and are fixedly installed at a certain position on the construction site. Rigid protective plates or flexible protective cloths are used for shielding and protection on the top and sides. At present, both protective plates and protective cloths are installed with fixed connections, such as screws, welding or clamping, which requires a lot of manpower and material resources during installation and disassembly. It is also easy to damage the protective plates or protective cloths, resulting in the inability to reuse the materials. In addition, due to the limited elasticity of the protective plates or protective cloths themselves, the top protective plates or protective cloths are easily damaged by falling debris. Summary of the invention

[0003] In view of the technical problems in the prior art, the present invention provides an assembled temporary steel bar shed, comprising a supporting frame, a flexible protective cloth and a connecting mechanism, wherein the bottom of the supporting frame is supported on the ground, and the flexible protective cloth is movably connected to the supporting frame through the connecting mechanism, and the connecting mechanism comprises two fixed plates, two movable plates and two groups of connecting springs, the two fixed plates are symmetrically arranged about the center line of the supporting frame, and are installed on the top surface edge of the supporting frame, the two movable plates are respectively slidably connected to the two fixed plates through an adjusting component, and the sliding direction is a vertical direction, a clamping space is formed between the movable plate and the fixed plate, the two groups of connecting springs are symmetrically arranged about the center line of the supporting frame, and one end of each group of connecting springs is connected to the side bottom end of the supporting frame through a bracket, the two ends of the flexible protective cloth respectively pass through the two clamping spaces and are fixedly connected to the other end of the connecting spring, and the flexible protective cloth is fixedly laid on the top and two sides of the supporting frame under the elastic force of the two groups of connecting springs.

[0004] Furthermore, the connecting mechanism also includes two groups of compression springs and two pressure plates. The two groups of compression springs are fixedly connected to the two movable plates respectively. The pressure plate is fixedly connected to one end of the compression spring away from the movable plate. The pressure plate fits tightly with the flexible protective cloth under the elastic force of the compression spring.

[0005] Furthermore, a first roller is rotatably mounted on the fixed plate, the first roller is located below the pressure plate, and both ends of the flexible protective cloth are fixedly connected to the connecting spring via the first roller.

[0006] Furthermore, the two first rollers are respectively installed on the sides of the two fixing plates that are away from each other.

[0007] Furthermore, the bracket is slidably connected to the side of the support frame, and the sliding direction is a vertical direction. The bracket and the support frame are locked by bolts.

[0008] Furthermore, a winding assembly is installed on the side of the support frame, and the winding assembly is located at one end of the support frame close to the top. The two ends of the flexible protective cloth are fixedly connected to the connecting springs via the two winding assemblies respectively. When the bracket slides upward relative to the support frame, the winding assembly winds up the flexible protective cloth. When the bracket slides downward relative to the support frame, the winding assembly releases the flexible protective cloth.

[0009] Furthermore, the winding assembly includes at least two second rollers and a mounting frame cooperating with the second rollers, the second rollers are rotatably mounted on the mounting frame, at least two of the second rollers are spaced apart in the vertical direction, one of the mounting frames is rotatably connected to the side of the support frame through a fixed rod, and the other mounting frame is rotatably connected to the side of the support frame through a movable rod, the end of the flexible protective cloth is fixedly connected to the connecting spring after passing through at least two second rollers, when the bracket slides upward relative to the support frame, the second roller moves away from the side of the support frame driven by the movable rod, and when the bracket slides downward relative to the support frame, the second roller moves close to the side of the support frame driven by the movable rod.

[0010] Furthermore, the winding assembly also includes a return spring, which corresponds to the movable rod one by one. The return spring is sleeved on the outside of the movable rod, and the two ends of the return spring are respectively fixedly connected to the mounting bracket and the support frame. When the bracket is located at the bottom end of the side of the support frame, the return spring is in a compressed state and the elastic force is maximum.

[0011] Furthermore, the adjustment assembly includes two mounting holes on the fixed plate, two sliding posts and two pin shafts on the movable plate. The sliding posts are slidably mounted in the mounting holes. The sliding posts are provided with a plurality of through holes at intervals along their length direction. The two pin shafts correspond one to one with the two sliding posts. The pin shafts are slidably mounted on the fixed plate and are located on one side of the mounting hole. When one end of the pin shaft slides into the mounting hole and cooperates with the through hole, the movable plate and the fixed plate are relatively fixed. Otherwise, the movable plate and the fixed plate slide relatively.

[0012] Beneficial effects:

[0013] 1. In the present invention, by setting two fixed plates, two movable plates and two groups of connecting springs, the limit between the movable plate and the fixed plate and the elastic force of the connecting springs can be used to conveniently and quickly realize the assembly and disassembly of the flexible protective cloth. Compared with the existing fixing methods such as screws or welding, the flexible protective cloth will not be damaged, so that the flexible protective cloth can be reused. At the same time, it can ensure that the flexible protective cloth will not fold, thereby improving the aesthetic effect. In addition, the elastic force of the connecting springs can also be used to effectively buffer the fallen debris, thereby extending the service life of the flexible protective cloth and avoiding the safety risks caused by the secondary falling of debris, thereby improving the protective effect of the steel shed. Specifically, when debris falls on the flexible protective cloth, the kinetic energy of the debris will cause the flexible protective cloth to sink inward, thereby driving the connecting springs on both sides to stretch. In this process, the kinetic energy of the falling debris can be offset by the elasticity of the flexible protective cloth itself and the buffering of the two groups of connecting springs. Combined with the setting of the movable plate being slidably connected to the fixed plate through an adjusting component, the installation of flexible protective cloths of different thicknesses can be met.

[0014] 2. In the present invention, by setting two groups of compression springs and two pressure plates, on the one hand, the elastic force of the compression springs can be used to improve the fixing effect of the flexible protective cloth, thereby improving the wind resistance of the flexible protective cloth, and on the other hand, the flexible protective cloth can be flattened to further prevent the flexible protective cloth from folding; by setting the first roller, the friction resistance of the flexible protective cloth during movement can be reduced, the installation and disassembly efficiency can be improved, and at the same time, the flexible protective cloth can be prevented from being damaged due to friction; combined with the setting that the two first rollers are respectively installed on the side of the two fixed plates away from each other, it can be ensured that the flexible protective cloth will not contact the side of the fixed plate at the corner, thereby further reducing the friction resistance of the flexible protective cloth during movement.

[0015] 3. In the present invention, by setting a sliding connection between the bracket and the side of the support frame, the shielding area of ​​the side of the support frame by the flexible protective cloth can be conveniently adjusted to meet different usage requirements. Combined with the setting of bolt locking, the initial elastic force of the connecting spring can be adjusted, thereby ensuring the firmness of the structure while improving the assembly and disassembly efficiency.

[0016] 4. In the present invention, the winding and releasing of the flexible protective cloth can be realized through the setting of the winding component, so as to ensure the fixing effect of the flexible protective cloth while preventing the flexible protective cloth from scattering. In addition, it can also avoid the occurrence of damage to the flexible protective cloth due to pulling. Specifically, when the bracket slides upward, the flexible protective cloth on the top will become loose and fall, thereby reducing or even losing the protective effect. At this time, the excess flexible protective cloth is wound up by the winding component to ensure that the top flexible protective cloth always has a certain tension. When the bracket slides downward, due to the limited length of the flexible protective cloth, the elasticity of the flexible protective cloth itself will be destroyed, and in severe cases, the flexible protective cloth will be torn. At this time, the flexible protective cloth is released by the winding component. , which can supplement the moving length; combined with the settings of at least two second rollers, the mounting frame fixing rod and the movable rod, the movement of the movable rod can be used to compensate for the length change of the flexible protective cloth during the movement of the bracket, ensuring that the flexible protective cloth on the top is always in the best state; through the setting of the reset spring, automatic compensation can be achieved, that is, when the bracket slides upward, the second roller will move away from the side of the support frame under the drive of the movable rod, and when the bracket slides downward, the second roller will move close to the side of the support frame under the drive of the movable rod. When the bracket is located at the bottom end of the side of the support frame, the reset spring is in a compressed state, and the setting with the maximum elastic force can limit the downward sliding position of the bracket.

[0017] 5. In the present invention, by setting two mounting holes, two sliding columns, two pins and multiple through holes, the height of the clamping space between the movable plate and the fixed plate can be adjusted by utilizing the cooperation of the through holes of the pins to meet the installation requirements of flexible protective cloths of different thicknesses.

[0033] The present invention provides a temporary assembled steel bar shed, such as Figures 1 to 5As shown, it includes a support frame 1, a flexible protective cloth 2 and a connecting mechanism. The bottom of the support frame 1 is supported on the ground. The support frame 1 is assembled from a criss-cross top frame and a plurality of columns arranged at the corners of the top frame to ensure its structural strength. To facilitate the rapid installation and disassembly of the support frame 1, the top frame can be assembled and connected in two parts. The flexible protective cloth 2 is movably connected to the support frame 1 through the connecting mechanism. The flexible protective cloth 2 can be freely folded and has a certain toughness and can bear a certain impact force. To improve the protective effect of the steel shed, a protective plate can be arranged between the top frame and the flexible protective cloth 2, wherein the protective plate can be a steel structure sandwich panel or a color pressure plate. The connecting mechanism includes two fixed plates 3, two movable plates 4 and two groups of connecting springs 5. The two fixed plates 3 are symmetrically arranged about the center line of the support frame 1 and are installed on the top edge of the support frame 1. The two movable plates 4 are slidably connected to the two fixed plates 3 through adjustment components 6, and the sliding direction is vertical. A clamping space is formed between the movable plate 4 and the fixed plate 3. The two groups of connecting springs 5 ​​are symmetrically arranged about the center line of the support frame 1, and one end of each group of connecting springs 5 ​​is connected to the bottom end of the side of the support frame 1 through a bracket 7, wherein each group of connecting springs 5 ​​includes a plurality of springs arranged at intervals in the horizontal direction. The two ends of the flexible protective cloth 2 respectively pass through the two clamping spaces and are fixedly connected to the other end of the connecting spring 5. The flexible protective cloth 2 is fixedly laid on the top and two sides of the support frame 1 under the elastic force of the two groups of connecting springs 5.

[0034] In the present embodiment, by setting two fixed plates 3, two movable plates 4 and two groups of connecting springs 5, the limit between the movable plate 4 and the fixed plate 3 and the elastic force of the connecting springs 5 ​​can be used to conveniently and quickly realize the assembly and disassembly of the flexible protective cloth 2. Compared with the existing fixing methods such as screws or welding, the flexible protective cloth 2 will not be damaged, so that the flexible protective cloth 2 can be reused. At the same time, it can ensure that the flexible protective cloth 2 will not fold, thereby improving the aesthetic effect. During specific installation or disassembly, the support frame 1 is first fixed to the ground, and then the two fixed plates 3 are fixedly installed on the two side edges of the top of the support frame 1, and the movable plate 4 is connected to the fixed plate 3 through the connecting mechanism. Then, the flexible protective cloth 2 is laid on the top of the support frame 1, and the two ends of the flexible protective cloth 2 are passed through the clamping space formed by the two fixed plates 3 and the movable plate 4, so that the two ends are laid on both sides of the support frame 1 until. The flexible protective cloth 2 is fully unfolded and the connecting spring 5 is finally connected to the side of the supporting frame 1 through the bracket 7. It can be fixed here by bolts, and the end of the flexible protective cloth 2 is fixed to the connecting spring 5 to ensure that the flexible protective cloth 2 has a certain tension; in addition, the elastic force of the connecting spring 5 can also be used to effectively buffer the fallen debris, thereby extending the service life of the flexible protective cloth 2 and avoiding the safety risks caused by the secondary falling of debris, thereby improving the protection effect of the steel shed. Specifically, when debris falls on the flexible protective cloth 2, the kinetic energy of the debris will cause the flexible protective cloth 2 to sink inward, thereby driving the connecting springs 5 ​​on both sides to stretch. In this process, the elasticity of the flexible protective cloth 2 itself and the buffering of the two groups of connecting springs 5 ​​can offset the kinetic energy of the falling debris. Combined with the setting of the movable plate 4 slidingly connected to the fixed plate 3 through the adjustment component 6, it can meet the installation of flexible protective cloths 2 of different thicknesses.

The pressure plate 9 is fixedly connected to one end of the compression spring 8 away from the movable plate 4. The pressure plate 9 is tightly fitted with the flexible protective cloth 2 under the elastic force of the compression spring 8, which can be achieved by adjusting the position between the movable plate 4 and the fixed plate 3. To ensure that the flexible protective cloth 2 can move freely under the elastic force of the connecting spring 5, the elastic force of the connecting spring 5 is much greater than the elastic force of the compression spring 8.

[0036] In this embodiment, by providing two groups of compression springs 8 and two pressure plates 9, on the one hand, the elastic force of the compression springs 8 can be utilized to improve the fixing effect of the flexible protective cloth 2, thereby improving the wind resistance of the flexible protective cloth 2; on the other hand, the flexible protective cloth 2 can also be flattened to further prevent the flexible protective cloth 2 from folding.

[0037] In the present invention, preferably, Figure 1 , Figure 2 and Figure 6 As shown, a first roller 10 is rotatably mounted on the fixed plate 3, and the first roller 10 is located below the pressure plate 9.

[0040] In this embodiment, by setting a sliding connection between the bracket 7 and the side of the support frame 1, the flexible protective cloth 2 on the side of the support frame 1 can be opened or closed, thereby conveniently adjusting the shielding area of ​​the side of the support frame 1 by the flexible protective cloth 2 to meet different usage requirements. Combined with the bolt locking setting, the position of the bracket 7 can be fixed, and the initial elastic force of the connecting spring 5 can be adjusted, thereby ensuring the firmness of the structure while improving the assembly and disassembly efficiency.

It is further preferred that the second roller 11 connected to the fixed rod 13 is just located directly below the first roller 10.
