Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a steel structure scaffolding for decoration construction. Background Technology

[0002] When carrying out wall decoration construction, scaffolding is usually erected to ensure the smooth construction process. During the operation, workers often need to transport materials or pass tools to each other.

[0003] A search revealed a steel scaffolding disclosed in patent document CN114232979B, comprising multiple horizontal bars and multiple vertical bars. The vertical bars are arranged between the horizontal bars, and each horizontal bar has a connector installed at both ends. Adjacent connectors are combined to form a fixing ring. Each horizontal bar has a thickened portion on its opposite surface, and each thickened portion has a slide rail on its opposite surface. A frame is provided between the horizontal bars, and both ends of the frame are inserted into the slide rail. A sealing plate is provided at the lower end of the frame, and a storage shell is provided at the lower end of the sealing plate. Fixing holes are provided on both sides of the frame inside one slide rail, and pull ropes are tied and fixed in the fixing holes. A winding mechanism for winding the pull ropes is installed on the outer wall of one horizontal bar.

[0004] Based on the above research, it was found that existing steel scaffolding requires materials to be retrieved and placed from the outside of the scaffolding when passing materials. This requires workers to lean out of the scaffolding, which poses a certain danger. In addition, scaffolding is generally erected on the outside of the building's exterior wall, with the inside close to the exterior wall, which basically does not meet the conditions for setting up material boxes (i.e., storage shells). The outside usually needs to be equipped with protective netting, which is also inconvenient for setting up material boxes. As a result, the existing material box structure is difficult to meet the actual use needs. Therefore, a steel structure scaffolding for decoration construction is needed. Utility Model Content

[0005] The purpose of this application is to provide a steel structure scaffold for decoration construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a steel structure scaffold for decoration construction, comprising scaffold vertical pipes, scaffold horizontal pipes, and scaffold longitudinal pipes. The intersections of the scaffold vertical pipes and scaffold horizontal pipes, the scaffold horizontal pipes and scaffold longitudinal pipes, and the scaffold vertical pipes and scaffold longitudinal pipes are all fixedly connected by connecting couplers. The two rows of scaffold vertical pipes on opposite sides are also fixed with reinforcing braces by connecting couplers. A working platform is erected at the upper end of the scaffold longitudinal pipe, and the working platform is provided in multiple layers arranged vertically.

[0007] The scaffolding longitudinal tubes and the lower end of the working platform are equipped with a hoisting structure. The hoisting structure extends in the same direction as the scaffolding horizontal tubes and extends to both ends of the scaffolding.

[0008] A material box is installed at the lower end of the hoisting structure, and the hoisting structure is slidably connected to the material box through a sliding connector.

[0009] The material box includes a lifting frame, a guide rod, and a lifting box. The upper end of the lifting frame is fixedly connected to the lower end of the sliding connector. The upper end of the guide rod is fixed to the inner top wall of the lifting frame. The lower end of the guide rod moves through the box wall of the lifting box. A limiting component is installed at the lower end of the guide rod to limit the movement of the lifting box.

[0010] The limiting device limits the lifting box when it descends to the bottom of the hanging frame and is located in the middle of two adjacent working platforms, and when it rises into the hanging frame and there is a gap between it and the top wall of the hanging frame.

[0011] Preferably, the lower end of the guide rod is provided with a mounting groove;

[0012] Limiting components include:

[0013] The limiting block has one end slidably connected to the mounting groove. The upper end of the limiting block is a horizontal surface, and the bottom of the limiting block and the side wall of the limiting block away from the guide rod form an arc-shaped curved surface.

[0014] The second spring is located in the mounting groove, and its two ends are fixed to the inner side wall of the mounting groove and one end of the limiting block, respectively.

[0015] A limit groove is provided on the upper part of the lifting box, and the limit groove is connected to the through hole through which the guide rod passes;

[0016] When the lifting box moves downward, causing the limiting block to move into the limiting groove, the limiting block pops out under the elastic force of the second spring and presses against the top wall of the limiting groove.

[0017] When the lifting box moves upward, causing the limit block to move to the bottom of the lifting box, the limit block will pop out under the elastic force of the second spring and press against the bottom surface of the lifting box.

[0018] Preferably, the material box further includes a release structure for the contact limit block to limit the movement of the contact limit block, the release structure including:

[0019] The abutment sleeve is movably fitted at the lower end of the guide rod. When the abutment sleeve moves upward, it presses against the limiting block and compresses the limiting block into the mounting groove.

[0020] The elastic connector is used to elastically connect the sleeve to the lower end of the lifting box.

[0021] Preferably, the elastic connector includes a connecting plate and a first spring. The upper surface of the connecting plate is fixed to the lower end of the abutment, and the connecting plate is elastically connected to the lower end of the lifting box through the first spring.

[0022] Preferably, the hoisting structure includes a connecting rod and a slide rail. The upper end of the connecting rod is fixed to the lower end of the working platform by a support rod. One side of the slide rail is fixed to one side of the connecting rod. The slide rail has a horizontally extending and downward-opening slide rail, which is a T-shaped groove.

[0023] The sliding connector includes pulleys, a hanger rod, and a connector. There are two pulleys, which are respectively rolled and embedded on both sides of the slide. The hanger rod is located between the two pulleys and is rotatably connected to the two pulleys. The lower end of the hanger rod extends to the top of the hanging frame. The lower end of the hanger rod is detachably fixed to the top of the hanging frame through the connector.

[0024] Preferably, a flexible anti-collision guard is fixed at the lower end of the lifting frame, and the flexible anti-collision guard is movablely installed on the outside of the lifting box and the connecting plate.

[0025] Preferably, both the connecting rod and the slide rail are multi-section assembly structures, wherein the outer ends of the slide rails at both ends are fixed with end plates by bolts.

[0026] In summary, the technical effects and advantages of this utility model are as follows:

[0027] 1. In this utility model, by setting up a hoisting structure, sliding connectors and material boxes, when materials need to be transported on the work platform, the construction personnel only need to pull down the lifting box, place the materials in the lifting box, then raise the lifting box and push the hoisting frame to give the lifting box power, so that the material box can move along the hoisting structure to the top of another work platform under the sliding action of the sliding connectors. The construction personnel on the other work platform can then pull down the lifting box again to take out the materials. Although the movement of the material box is pushed manually, the operation is convenient.

[0028] Meanwhile, the material boxes suspended under the upper working platform are convenient for construction workers on the lower working platform to use. The entire operation does not require protruding outside the steel scaffolding, avoiding potential dangers and making it easier to store and retrieve materials.

[0029] In addition, the lifting design can effectively prevent the material boxes from affecting the work of construction workers during the transportation of materials, ensuring both convenience and safety.

[0030] 2. In this utility model, when the lifting box moves up and down, the limiting block moves to the bottom of the lifting box and into the limiting groove. Under the elastic force of the second spring, the limiting block pops out and presses against the bottom surface of the lifting box or the top wall of the limiting groove.

[0031] Specifically, when the lifting box is pulled down, the limiting groove of the lifting box moves to the position corresponding to the limiting block. Under the elastic force of the second spring, the limiting block pops out, so that the end face of the limiting block abuts against the top wall of the limiting groove, limiting the lifting box and preventing it from disengaging from the guide rod after it descends. When the lifting box rises, when the bottom of the lifting box is higher than the limiting block, the limiting block also pops out under the elastic force of the second spring, so that the end face of the limiting block abuts against the bottom surface of the lifting box, keeping the lifting box stable during movement.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Example: Reference Figures 1-6 The steel structure scaffolding for decoration construction shown includes two rows of scaffolding vertical pipes 1, two rows of scaffolding horizontal pipes 2, and multiple rows of scaffolding longitudinal pipes 3. (Refer to...) Figure 1 It can be seen that two rows of scaffolding vertical pipes 1 are arranged front and back, two rows of scaffolding horizontal pipes 2 are located between the two rows of scaffolding vertical pipes 1 and correspond to the inner side of the two rows of scaffolding vertical pipes 1 respectively, and multiple rows of scaffolding longitudinal pipes 3 are arranged vertically and evenly. The intersections of scaffolding vertical pipes 1 and scaffolding horizontal pipes 2, scaffolding horizontal pipes 2 and scaffolding longitudinal pipes 3, and scaffolding vertical pipes 1 and scaffolding longitudinal pipes 3 are all fixedly connected by connecting fasteners 4. The side of the two rows of scaffolding vertical pipes 1 that is far apart from each other is also fixed with reinforcing braces 5 by connecting fasteners 4. Multiple working platforms 6 are erected on multiple rows of scaffolding longitudinal pipes 3, and multiple working platforms 6 are arranged vertically in sequence.

[0042] The lower end of the scaffold longitudinal tube 3 and the working platform 6 is equipped with a hoisting structure 7. The hoisting structure 7 extends in the same direction as the scaffold horizontal tube 2 and extends to both ends of the scaffold body.

[0043] A material box 9 is installed at the lower end of the hoisting structure 7, and the hoisting structure 7 is slidably connected to the material box 9 through a sliding connector 8;

[0044] The material box 9 includes a hanging frame 91, a guide rod 92, and a lifting box 93. The upper end of the hanging frame 91 is fixedly connected to the lower end of the sliding connector 8. The upper end of the guide rod 92 is fixed to the inner top wall of the hanging frame 91. The lower end of the guide rod 92 moves through the box wall of the lifting box 93. A limiting component for limiting the lifting box 93 is installed at the lower end of the guide rod 92.

[0045] Based on the above structure, when materials need to be transported on the work platform 6, the construction personnel only need to pull down the lifting box 93, place the materials in the lifting box 93, then raise the lifting box 93 and push the lifting frame 91 to give power to the lifting box 93, so that the material box 9 can move along the lifting structure 7 to the top of another work platform 6 under the sliding action of the sliding connector 8. The construction personnel on the other work platform 6 can then pull down the lifting box 93 again to take out the materials. Although the movement of the material box 9 is pushed by manpower, the operation is convenient.

[0046] Meanwhile, the material box 9 suspended under the upper working platform 6 is convenient for construction workers on the lower working platform 6 to use. The entire operation does not require protruding outside the steel scaffolding, avoiding potential dangers and making it easier to store and retrieve materials.

[0047] In addition, the lifting design can effectively prevent the material box 9 from affecting the work of construction personnel during the transportation of materials. The lowest position of the lifting box 93 after it is raised is set to be higher than the height of the construction personnel and the construction work space, ensuring both convenience and safety.

[0048] The limiting components limit the lifting box 93 when it descends to below the hanging frame 91 and is located in the middle of the two adjacent working platforms 6, and when the lifting box 93 rises into the hanging frame 91 and there is a gap between it and the top wall of the hanging frame 91, thereby ensuring that the lifting box 93 will not descend during the movement.

[0049] Furthermore, a mounting groove 921 is provided at the lower end of the guide rod 92;

[0050] Limiting components include:

[0051] Limiting block 96, one end of which is slidably connected to the mounting groove 921. The upper end of the limiting block 96 is a horizontal surface, and the bottom of the limiting block 96 and the side wall of the limiting block 96 away from the guide rod 92 form an arc-shaped curved surface.

[0052] The second spring 98 is located in the mounting groove 921, and its two ends are fixed to the inner side wall of the mounting groove 921 and one end of the limiting block 96, respectively.

[0053] A limiting groove 931 is provided on the upper part of the lifting box 93, and the limiting groove 931 is connected to the through hole through which the guide rod 92 passes;

[0054] During use, when the lifting box 93 moves downward, causing the limiting block 96 to move into the limiting groove 931, the limiting block 96 pops out under the elastic force of the second spring 98 and presses against the top wall of the limiting groove 931.

[0055] When the lifting box 93 moves upward, causing the limiting block 96 to move to the bottom of the lifting box 93, the limiting block 96 will pop out under the elastic force of the second spring 98 and press against the bottom surface of the lifting box 93.

[0056] Specifically, when the lifting box 93 is pulled down (before pulling down, the limiting block 96 needs to be pressed into the mounting groove 921 to release the limiting), when the limiting groove 931 of the lifting box 93 moves to the position corresponding to the limiting block 96, the limiting block 96 pops out under the elastic force of the second spring 98, so that the end face of the limiting block 96 abuts against the inner top wall of the limiting groove 931, limiting the lifting box 93 so that the lifting box 93 cannot disengage from the guide rod 92 after it descends; when the lifting box 93 is pushed up, when the lifting box 93 rises to the bottom higher than the limiting block 96, the limiting block 96 also pops out under the elastic force of the second spring 98, so that the end face of the limiting block 96 abuts against the bottom surface of the lifting box 93, so that the lifting box 93 remains stable during the movement.

[0057] Furthermore, the supply box 9 also includes a release structure for the contact limit block 96 to limit the movement of the contact limit block 96. The release structure includes:

[0058] Abutment sleeve 94 is movably sleeved at the lower end of guide rod 92. When abutment sleeve 94 moves upward, it presses against limiting block 96 and compresses limiting block 96 into mounting groove 921.

[0059] The elastic connector, the sleeve 94 is elastically connected to the lower end of the lifting box 93 through the elastic connector;

[0060] The elastic connector includes a connecting plate 95 and a first spring 97. The upper surface of the connecting plate 95 is fixed to the lower end of the abutment 94, and the connecting plate 95 is elastically connected to the lower end of the lifting box 93 through the first spring 97.

[0061] When it is necessary to contact the limiting block 96 at the bottom of the lifting box 93 to limit the lifting box 93, the construction personnel only need to push the connecting plate 95 upward, so that the connecting plate 95 overcomes the elastic force of the first spring 97, thereby driving the abutment 94 to move upward. When the abutment 94 moves upward, it squeezes the limiting block 96 and compresses the limiting block 96 into the mounting groove 921, thereby releasing the limiting effect of the limiting block 96 on the lifting box 93, making it convenient for the construction personnel to pull down the lifting box 93 for storage or retrieval of materials.

[0062] Furthermore, the hoisting structure 7 includes a connecting rod 71 and a slide rail 72. The upper end of the connecting rod 71 is fixed to the lower end of the working platform 6 (or the scaffolding longitudinal tube 3) via a support rod 711. One side of the slide rail 72 is fixed to one side of the connecting rod 71. A horizontally extending slide rail 721 with an opening facing downwards is provided on the slide rail 72. The slide rail 721 is a T-shaped groove that is wider at the top and narrower at the bottom. The opening of the slide rail 721 is located at the lower end.

[0063] The sliding connector 8 includes pulleys 81, a hanger rod 82, and a connector 83. Two pulleys 81 are provided and are respectively rolled and embedded in the two sides of the wider groove at the top of the slide rail 721. The hanger rod 82 is located between the two pulleys 81 and is rotatably connected to the two pulleys 81. The lower end of the hanger rod 82 passes through the lower opening of the slide rail 721 and extends to the top of the hanging frame 91. The hanger rod 82 is clearance-fitted with the lower opening of the slide rail 721. The lower end of the hanger rod 82 is detachably fixed to the top of the hanging frame 91 through the connector 83.

[0064] When the construction workers push the material box 9, the material box 9 drives the pulley 81 to roll in the slide 721, which makes the movement of the material box 9 easier and allows the construction workers to apply greater force to the material box 9, thus making the material box 9 move a longer distance and meeting the material transportation needs between multiple working platforms 6 on the same plane.

[0065] Furthermore, a flexible anti-collision guardrail 99 is fixed at the lower end of the lifting frame 91. The flexible anti-collision guardrail 99 is installed on the outside of the lifting box 93 and the connecting plate 95. The flexible anti-collision guardrail 99 can play a certain protective role and prevent the lower part of the material box 9 from accidentally colliding with the construction personnel, thus avoiding injury to the construction personnel.

[0066] Furthermore, both the connecting rod 71 and the slide rail 72 are multi-section assembly structures. The outer ends of the slide rail 72 at both ends are fixed with end plates 722 by bolts. The multi-section assembly of the connecting rod 71 and the slide rail 72 is convenient to adapt to the transportation needs of materials of different lengths. At the same time, the end plates 722 can prevent the pulley 81 from falling off when it moves to the end, ensuring the reliability of the overall device during transportation.

[0067] The working principle of this utility model is as follows: In daily use, when materials need to be transported on the work platform 6, the construction personnel first push the connecting plate 95 upward, so that the connecting plate 95 overcomes the elastic force of the first spring 97, thereby driving the abutment 94 to move upward. When the abutment 94 moves upward, it squeezes the limiting block 96 and compresses the limiting block 96 into the mounting groove 921, thereby releasing the limiting effect of the limiting block 96 on the lifting box 93. Then, simply pull down the lifting box 93 and place the materials in the lifting box 93. Then, lift the lifting box 93. When the lifting box 93 rises, when the lifting box 93 is raised to the bottom higher than the limiting block 96, the limiting block 96 also pops out under the elastic force of the second spring 98, so that the end face of the limiting block 96 abuts against the bottom surface of the lifting box 93, so that the lifting box 93 remains stable during the movement.

[0068] Afterwards, the construction workers push the lifting frame 91 to provide power to the lifting box 93, which enables the material box 9 to drive the pulley 81 to roll in the slide 721. This makes the movement of the material box 9 easier, allowing the construction workers to apply greater force to the material box 9, thus enabling the material box 9 to move a longer distance. This meets the material transportation needs between multiple working platforms 6 on the same plane. The material box 9 eventually moves to the top of another working platform 6, where the construction workers pull down the lifting box 93 again to retrieve the materials. Although the movement of the material box 9 is driven by manpower, the operation is convenient.

[0069] Meanwhile, the material box 9 suspended under the upper working platform 6 is convenient for construction workers on the lower working platform 6 to use. The entire operation does not require protruding outside the steel scaffolding, avoiding potential dangers and making it easier to store and retrieve materials.

[0070] Finally, the lifting design effectively prevents the material box 9 from interfering with the work of construction personnel during the transportation of materials, ensuring both convenience and safety.

[0071] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
