Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a movable and extendable scaffold used in a narrow space of a fertilizer trough and a construction method thereof. Background Art

[0002] Currently, construction workers rely on scaffolding to assist with waterproofing membrane installation in the narrow spaces of foundation pits. Common scaffolding is floor-standing, bulky, and multi-component. While the frame provides an operating platform, it is also immobile, leaving the already narrow space lacking for waterproofing membrane installation. Furthermore, installation and removal are cumbersome, time-consuming, and labor-intensive, requiring considerable movement. Summary of the Invention

[0003] In order to overcome the defects of the existing technology, a movable and extendable scaffolding for the narrow space of the fertilizer trough and a construction method thereof are provided to solve the problem of time-consuming and labor-intensive moving of the scaffolding when laying waterproof membrane in the narrow space of the foundation pit fertilizer trough.

[0004] To achieve the above purpose, a movable and extendable scaffold for the narrow space of a fertilizer tank is provided, comprising:

[0005] The suspended frame is movably set in the fertilizer trough;

[0006] Wing rods are respectively mounted on opposite sides of the upper portion of the suspended frame in a vertically adjustable manner, and walking rollers are adjustably mounted on the wing rods;

[0007] Walkway plates, with multiple layers of support rods arranged in the vertical direction respectively installed on the opposite sides of the lower part of the suspended frame, and the walkway plates are laid on the support rods corresponding to the opposite sides of the suspended frame.

[0008] Furthermore, a protective roof is installed on the top of the suspended frame.

[0009] Furthermore, the wing rod has a fixed end and a cantilevered end opposite to each other, and the fixed end is detachably mounted on the side of the suspended frame through a fastener.

[0010] Furthermore, the cantilever end is mounted with a base in an adjustable position, and the travel roller is mounted on the base.

[0011] Furthermore, friction-reducing rollers are respectively installed on opposite sides of the suspended frame.

[0012] Furthermore, the walkway boards are laid on each layer of the support rods.

[0013] Furthermore, one side of the walkway board is hinged to the support rod on one side of the suspended frame, and the other side of the walkway board is detachably mounted on the support rod on the other side of the suspended frame. When one layer of walkway boards is not in use, the other side of the one layer of walkway boards is flipped upward and detachably hung on the upper layer of support rods on one side of the suspended frame.

[0014] Furthermore, the fastener includes:

[0015] substrate;

[0016] A fixed side plate is vertically arranged on the base plate, and a first through groove is formed on one side of the fixed side plate;

[0017] The movable side panel is detachably mounted on one side of the fixed side panel. A second through slot is formed on the side of the movable side panel facing the fixed side panel. The second through slot and the first through slot together form a locking channel for the wing rod to pass through.

[0018] Furthermore, one end of the fixed side plate away from the base plate is connected to one end of the movable side plate through a tension screw, and a locking rod is installed on the other end of the movable side plate in a liftable manner. The base plate is provided with a locking hole, and the locking rod is detachably inserted into the locking hole.

[0019] The present invention provides a construction method of a movable and extendable scaffold for a narrow space of a fertilizer tank, comprising the following steps:

[0020] The suspended frame is movably arranged in the fertilizer trough;

[0021] Based on the horizontal distance from the side of the suspended frame to the wall of the fertilizer trough, the position of the walking roller on the wing rod is adjusted so that the walking roller is arranged above the outer wall of the notch of the fertilizer trough;

[0022] Based on the vertical distance from the wing rod to the outer wall of the slot, adjusting the position of the wing rod on the side of the suspended frame so that the outer wall of the slot is supported on the walking roller;

[0023] Based on the elevation of the current construction position on the side wall of the fertilizer trough, the walkway plates are laid on the corresponding support rods at opposite sides of the suspended frame, so that the elevation of the walkway plates is adapted to the elevation of the construction position;

[0024] Moving the suspended frame along the length direction of the fertilizer trough to complete the construction at the current elevation;

[0025] Based on the elevation of the next construction location, the walkway plates are laid on the support rods corresponding to the opposite sides of the suspended frame, so that the elevation of the walkway plates matches the elevation of the next construction location, thereby completing the construction of the next construction location.

[0026] The beneficial effects of the present invention are that the movable and extendable scaffolding for the narrow space of a fertilizer trough provides workers with a safe and reliable scaffolding tool within the narrow space of a fertilizer trough, and by being "movable", it is endowed with the characteristics of being simple, lightweight, economical and efficient. The movable and extendable scaffolding for the narrow space of a fertilizer trough of the present invention moves horizontally along the outer wall of the basement for construction until construction is completed from one end of the outer wall to the other. During this process, workers do not need to pause construction, climb out of the fertilizer trough, manually lift the scaffolding to the next point, and then return to the fertilizer trough space to continue construction. Construction workers can move vertically up and down along the side walls of the outer wall on the suspended frame to assist workers in construction at different heights.

[0039] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0040] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] Reference Figures 1 to 5 As shown, the present invention provides a movable and extendable scaffold for the narrow space of a fertilizer trough, comprising: a suspended frame 1, wing rods 2, and a walkway board 3.

[0042] The suspended frame 1 is movably arranged in the fertilizer tank 5. In the present embodiment, the suspended frame is constructed by using steel pipes and fasteners.

[0043] See Figure 1 As shown, the suspended frame includes vertical poles and horizontal poles. The number of vertical poles is at least four. In this embodiment, the four vertical poles are arranged in a matrix. The horizontal pole connects two adjacent vertical poles.

[0044] As a preferred embodiment, a protective roof is installed on the top of the suspended frame 1. When the working environment is complex and there is a risk of falling objects from high altitude, the protective roof is arranged on the suspended frame.

[0045] Continue to combine Figure 1 and Figure 2 As shown, wing rods 2 are respectively mounted on opposite sides of the upper portion of the suspended frame 1 in a vertically adjustable manner. Travel rollers 21 are also mounted on the wing rods 2 in a vertically adjustable manner.

[0046] In this embodiment, the wing bars are arranged in the horizontal direction. When the movable and extendable scaffolding for the narrow space of the manure tank of the present invention is used, the wing bars are arranged along the width direction of the manure tank. The wing bars 2 have a fixed end and a cantilevered end opposite to each other.

[0047] The fixed end of the wing rod 2 is detachably mounted on the side of the suspension frame 1 through a fastener 4. When the setting elevation of the wing rod needs to be adjusted, the wing rod is removed and then mounted on the vertical pole of the suspension frame at the specified elevation through the fastener.

[0048] The cantilevered end of the wing bar 2 is adjustably mounted with a base 22. The travel roller 21 is mounted on the base 22. When the position of the travel roller on the wing bar needs to be adjusted, the travel roller is removed and then mounted on the wing bar at the specified position through a fastener.

[0049] As a preferred embodiment, the fastener 4 includes: a base plate 41 , a fixed side plate 42 , and a movable side plate 43 .

[0050] For details, see Figure 3 and Figure 4 As shown, the base plate 41 is a rectangular plate. The fixed side plate 42 is vertically arranged on the base plate 41. A first through groove is formed on one side of the fixed side plate 42;

[0051] The movable side plate 43 is detachably mounted on one side of the fixed side plate 42. A second through slot is formed on the side of the movable side plate 43 facing the fixed side plate 42. The second through slot and the first through slot together form a locking channel for the wing rod 2 to pass through.

[0052] In this embodiment, the end of the fixed side plate 42, away from the base plate 41, is connected to one end of the movable side plate 43 via a tension screw 44. A locking rod 45 is detachably mounted on the other end of the movable side plate 43. The base plate 41 has a locking hole formed therein. The locking rod 45 is removably inserted into the locking hole.

[0053] In a preferred embodiment, a lug is connected to the side of the movable side panel facing away from the fixed side panel. The lug has a threaded hole. The threaded hole is coaxial with the lock hole. The locking rod has external threads. The screw is threaded into the threaded hole of the lug, and one end of the locking rod is removably inserted into the lock hole.

[0054] Combine Figure 1 and Figure 2 As shown, two opposite sides of the lower part of the suspended frame 1 are respectively installed with multiple layers of support rods 31 arranged in the vertical direction. The walkway boards 3 are laid on the support rods 31 at the corresponding positions on the two opposite sides of the suspended frame 1.

[0055] Preferably, a walkway board 3 is laid on each layer of support rods 31 to carry out construction at construction locations of different elevations.

[0056] In this embodiment, one side of the walkway board 3 is hinged to a support rod 31 on one side of the suspended frame 1. The other side of the walkway board 3 is detachably mounted on a support rod 31 on the other side of the suspended frame 1. When a layer of walkway boards 3 is not in use, the other side of the walkway board 3 is flipped upward and detachably suspended from a support rod 31 on the upper layer on one side of the suspended frame 1.

[0057] Recombination Figure 1 and Figure 2As shown, as a preferred embodiment, friction-reducing rollers 11 are respectively installed on two opposite sides of the suspension frame 1.

[0058] The friction-reducing rollers 11 on the side walls of the fertilizer trough serve as side wall contact points to reduce the friction resistance during the movement of the suspended frame and improve sliding convenience.

[0059] In this embodiment, based on the position of the fertilizer trough, the suspended frame is divided into an upper suspension body, a middle base and a lower suspension body.

[0060] Among them, the composition of the central base is:

[0061] The central base of the suspended frame is free from the constraints of the previous scaffolding grounded at the bottom of the fertilizer trough and unable to move, and now serves as a sliding base and gravity support. Therefore, the "central base" becomes the core of the suspended frame. The structure of the central base mainly includes the following:

[0062] ① The wing rod on the middle base is a Q235 steel pipe fitting that spans the space of the fertilizer trough. One end of the wing rod is placed on the outer wall of the slot on one side of the fertilizer trough (the basement roof), and the other end of the wing rod is placed on the outer wall of the slot on the other side of the fertilizer trough. In this way, the middle base is converted from the ground support force at the bottom of the fertilizer trough to the suspended support force at the top of the fertilizer trough.

[0063] ② In order to adapt to the height difference between the outer walls of the slots on both sides of the fertilizer trough, the wing rods across the fertilizer trough space are divided into upper wing rods and lower wing rods, and then the vertical rods are arranged, which are connected by 90° fasteners (such as Figure 5 As shown, the basic structure of the fasteners is the same as that of the running rollers. Two fasteners (set at 90 degrees) are used to connect and secure the crossbars to the vertical poles to form a solid base. Each upper and lower crossbar needs to be connected and secured to the vertical poles on both sides of the central base to enhance the stability of the base frame.

[0064] ③ Install running rollers at the wing rod's load point. This allows the weight of the central base to be transferred to the outer walls of the slot on both sides of the fertilizer trough through the running rollers. These running rollers also facilitate the longitudinal movement of the central base along the fertilizer trough. Furthermore, the wing rods can be extended to accommodate additional running rollers, depending on the available space in the underground garage roof. This can be used to construct a movable material platform attached to the central base, and counterweights can be placed to balance and stabilize the base.

[0065] ④ On the other hand, because the walking rollers are omnidirectional, in order to ensure that the frame does not deviate to the left or right during movement (so as not to fall into the fertilizer trough), friction-reducing rollers need to be arranged on the side panels of the middle base; thus, there is an "L-shaped double pulley combination" on the upper openings of both sides of the fertilizer trough, which ensures the linear sliding direction and safety of the middle base.

[0066] ⑤ Through steps ①, ②, ③, and ④, the "central base" is essentially complete. To further enhance the base's stability and accommodate the operating platform, another identical "central base" is placed longitudinally. Using longitudinal rods, the two "central bases" are connected to form a "tic-tac-toe" central base. This completes the movable base.

[0067] Secondly, the composition of the lower suspension.

[0068] Secondly, based on the "middle base", the "lower suspension body" is suspended downward and arranged, which mainly serves as an up and down channel and working platform. The specific steps are as follows:

[0069] ① The vertical rods arranged on the base extend downward. If the length is insufficient, friction-reducing rollers are arranged to extend and lengthen the vertical rods to facilitate the arrangement of the lower suspension body. The lower suspension rods must not touch the bottom of the fertilizer tank (always maintain a certain distance and be in a suspended state).

[0070] ② Using the suspended vertical poles as support, 90° fasteners were used to add and attach longitudinal and transverse steel pipes. These were used to arrange short steel pipe components, such as guardrails, operating platform support rods, and upper and lower step rods. The upper and lower step rods (300mm apart) were placed on the sidewall of the foundation pit (not the surface for coiled material paving), allowing for easy access without hindering the paving process. Only the guardrails and operating platform support rods were placed on one side of the basement's exterior wall, with the principle of stabilizing the structure and facilitating operations being the guiding principles.

[0071] ③ The attachment parts of the suspended vertical rods (except pulleys) must not come into contact with the side walls of the fertilizer trough to avoid affecting the moving points of the frame.

[0072] ④ When the depth of the fertilizer trough is large and a single vertical rod is not enough to reach the height of the working surface, a "pulley-type double fastener" can be arranged at the bottom of the vertical rod to continue to lengthen and extend the vertical rod.

[0073] Finally, the composition of the upper suspension.

[0074] Based on the "middle base", the "upper suspension body" is suspended upwards and arranged, which mainly serves to connect, reinforce and arrange the protective roof. The specific steps are as follows:

[0075] The vertical rods arranged on the base extend upward. When the length is insufficient, fasteners are arranged to lengthen and extend the vertical rods to facilitate the arrangement of the upper suspension body.

[0076] Relying on the suspended vertical poles, fasteners are used to add and attach longitudinal and transverse steel pipes to arrange the connecting rods of the vertical poles to form a stable "well shape".

[0077] When the working environment is complex and there is a risk of falling objects from height, a protective roof can be arranged on the upper suspension.

[0078] The present invention provides a construction method of a movable and extendable scaffold for a narrow space of a fertilizer tank, comprising the following steps:

[0079] S1. The suspended frame 1 is movably arranged in the fertilizer tank 5.

[0080] S2. Based on the horizontal distance from the side of the suspended frame 1 to the groove wall of the fertilizer trough 5, adjust the position of the walking roller 21 on the wing rod 2 so that the walking roller 21 is set above the outer wall 52 of the groove opening of the fertilizer trough 5.

[0081] S3. Based on the vertical distance between the wing rod 2 and the outer wall 52 of the slot, adjust the position of the wing rod 2 on the side of the suspended frame 1 so that the outer wall 52 of the slot is supported on the walking roller 21.

[0082] S4. Based on the elevation of the current construction position on the side wall 51 of the fertilizer trough 5, the walkway plate 3 is laid on the support rods 31 corresponding to the opposite sides of the suspended frame 1, so that the elevation of the walkway plate 3 is adapted to the elevation of the construction position.

[0083] S5. Move the suspended frame 1 along the length direction of the fertilizer trough 5 to complete the construction at the current elevation.

[0084] S6. Based on the elevation of the next construction location, the walkway slab 3 is laid on the support rods 31 corresponding to the opposite sides of the suspended frame 1, so that the elevation of the walkway slab 3 is adapted to the elevation of the next construction location, thereby completing the construction of the next construction location.

[0085] The movable and extendable scaffolding for the narrow space of a fertilizer trough of the present invention provides workers with a safe and reliable scaffolding tool in the narrow space of the fertilizer trough, and is given the characteristics of being simple, lightweight, economical and efficient by being "movable".

[0086] The present invention's movable and extendable scaffolding, used in the narrow space of a manure tank, moves horizontally along the basement exterior wall (i.e., one side of the manure tank), facilitating the installation of waterproofing membranes after one roll has been laid, followed by the installation of the second and third rolls, until the membranes are laid from one end of the exterior wall to the other. This process eliminates the need for workers to pause, climb out of the manure tank, manually lift the scaffolding to the next point, and then return to the manure tank to continue laying the membranes. (This example only illustrates the installation of membranes; the installation of extruded panels on the exterior wall can also be substituted.)

[0087] Construction workers can move vertically up and down along the side walls of the exterior wall on the suspended frame to help workers lay the rolls at different heights.

[0088] The width of the movable and extendable scaffolding used in the narrow space of the fertilizer trough of the present invention can be flexibly adjusted to adapt to fertilizer trough spaces of different widths (the distance between the outer wall side wall and the foundation pit side wall).

[0089] The height of the movable and extendable scaffolding for the narrow space of the fertilizer tank of the present invention can be flexibly adjusted to adapt to fertilizer tank spaces with different height differences (height differences between the outer wall top plate and the top of the foundation pit side wall).

[0090] The movable and extendable scaffold for the narrow space of the fertilizer trough of the present invention has the feature of mobility, thereby giving the advantages of saving rods, being simple, efficient and convenient, and adapting to small spaces and saving working space.

[0091] The movable and extendable scaffolding for the narrow space of the fertilizer trough of the present invention has the characteristics of mobility and complete rods and components, thereby providing the advantages of simplicity, efficiency and convenience, the advantages of adapting to small spaces and facilitating construction operations, and the advantages of guaranteed safety.

[0092] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention herein is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features having similar functions disclosed in this application.
