Description

Technical Field

[0001] This application relates to the field of construction scaffolding technology, specifically a construction scaffolding. Background Technology

[0002] Scaffolding, also known as construction scaffolding, is a temporary structural facility used in construction to provide workers with a working platform, supporting materials, and safety protection.

[0003] Most existing scaffolding is assembled and then fixed. During construction, traditional scaffolding can only be fixed indoors for workers to stand on. This means that some exterior wall projects of buildings need to be re-suspended for construction, increasing the burden of carrying tools. Furthermore, suspended construction lacks a stable foothold, increasing the difficulty of construction.

[0004] Therefore, this application provides a construction frame to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a construction scaffold that aims to solve the problem mentioned in the background art that existing construction scaffolds can only provide footholds indoors and cannot take care of the outside.

[0006] To achieve the above objectives, this application provides the following technical solution: a construction frame, including a base frame and brake wheels fixedly installed at the four corners of the bottom of the base frame. A longitudinally movable intermediate frame is telescopically connected to the top of the base frame, and a longitudinally movable top frame handrail is telescopically connected to the top of the intermediate frame. A screw jack with both ends connected to the base frame and the intermediate frame respectively is fixedly installed on the base frame. Several longitudinally arranged adjusting pin holes are opened at the four corners near the top of the intermediate frame, and an adjusting pin bolt that is screwed to the top frame handrail is inserted into one of the adjusting pin holes.

[0007] The top frame armrests have top side bars on both sides, and the middle frame has waist side bars on both sides. A footboard is fixedly installed on the top side bar for placing on the waist side bar or the top side bar.

[0008] The intermediate frame has two cantilever rods symmetrically hinged to one side of one of the waist side rods for suspending the footboard on both sides. In this way, the base frame serves as the fundamental support, and its bottom brake wheels facilitate overall movement and fixation. The screw jack serves as the core lifting device; by adjusting the height of the intermediate frame, the construction scaffold can adapt to the needs of different floors or construction surfaces. The telescopic connection between the intermediate frame and the top frame handrail further expands the longitudinal working range of the construction scaffold. The footboard serves as a standing platform for workers and can be flexibly placed on the waist side rod or the top side rod depending on the construction location. The cantilever rod design breaks through the limitations of traditional construction scaffolds, allowing workers to work in areas inaccessible to traditional construction scaffolds, such as the exterior walls of buildings, by suspending the footboard.

[0009] Preferably, limiting plates are fixedly connected to both sides of the foot pedal, and a first locking bolt is threaded through the limiting plate and screwed to the waist side rod or the top side rod.

[0010] Preferably, the waist side rod and the top side rod are respectively provided with a first screw hole and a third screw hole for accommodating the first locking bolt screw connection.

[0011] Preferably, the two ends of the cantilever rod are respectively equipped with a second locking bolt and a third locking bolt. The second locking bolt passes through one end of the cantilever rod and is screwed to the intermediate frame, and the third locking bolt passes through the other end of the cantilever rod and is screwed to the side of the footboard.

[0012] Preferably, the foot pedal has a fourth screw hole on both sides without the limiting plate for screwing in the third bolt, and the intermediate frame has a second screw hole for screwing in the second bolt.

[0013] Preferably, the top side rod is fixedly installed on the top frame handrail by a detachable structure, the detachable structure including a locking block fixedly connected to the bottom of both ends of the top side rod and a locking frame fixedly connected to the top frame handrail and corresponding to the locking block for inserting the locking block.

[0014] Preferably, the crossbars on both sides of the top frame handrail are covered with sleeves.

[0015] This construction scaffold, through the extension, adjustment, and combination of multiple components, can flexibly meet the needs of indoor and outdoor construction.

[0016] The construction frame has a base frame as its foundation support, and its bottom brake wheels facilitate overall movement and fixation.

[0017] The construction scaffold uses a screw jack as its core lifting device. By adjusting the height of the intermediate frame, the scaffold can adapt to the needs of different floors or construction surfaces. The telescopic connection between the intermediate frame and the top frame handrail further expands the longitudinal working range of the scaffold. The footboard serves as a standing platform for workers and can be flexibly placed on the waist side bar or the top side bar depending on the construction location. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] This embodiment provides a construction frame, such as Figures 1-4 As shown, the construction frame includes a base frame 1 and brake wheels 11 fixedly installed at the four corners of the bottom of the base frame 1. The top of the base frame 1 is telescopically connected to a longitudinally movable intermediate frame 2. The top of the intermediate frame 2 is telescopically connected to a longitudinally movable top frame handrail 3. The base frame 1 is fixedly installed with screw jacks 5 that are connected to the base frame 1 and the intermediate frame 2 at both ends respectively. Several longitudinally arranged adjusting pin holes 22 are opened at the four corners of the intermediate frame 2 near the top. An adjusting pin 23 that is screwed to the top frame handrail 3 is inserted into one of the adjusting pin holes 22.

[0022] The top frame armrest 3 has top side bars 31 on both sides opposite to each other, and the middle frame 2 has waist side bars 21 on both sides opposite to each other. A footboard 4 for placing on the waist side bar 21 or the top side bar 31 is fixedly installed on the top side bar 31.

[0023] The middle frame 2 is symmetrically hinged to one side of one of the waist side bars 21, with two cantilever bars 6 for cantilevering the footboard 4 on both sides.

[0024] In use, the construction frame is moved to the designated position by the brake wheel 11 and the brake wheel 11 is fixed to ensure the stability of the construction frame; the screw jack 5 is operated to adjust the intermediate frame 2 to a suitable height to meet the needs of the construction surface. According to the construction range, the intermediate frame 2 and the top frame handrail 3 are extended and locked by adjusting the adjusting pin 23 and adjusting pin hole 22 to expand the longitudinal working space of the construction frame; the footboard 4 is placed on the waist side bar 21 or the top side bar 31 to provide a stable standing platform for workers; when construction is required on the exterior wall of the building, the cantilever bar 6 is extended and one end of the footboard 4 is cantilevered to the outside of the window. Before this, the other end of the footboard 4 is fixedly installed on one side of the intermediate frame 2, so that both ends of the footboard 4 are provided with stable support points. Workers can stand on the footboard 4 to work. During this period, the top frame handrail 3 can also be lifted to contact the ceiling by the screw jack 5, so that both ends of the entire device are limited, further improving the stability and safety when cantilevered.

[0025] Specifically, limiting plates 41 are fixedly connected to both sides of the foot pedal 4. The limiting plates 41 have first locking bolts 42 that are screwed to the waist side rod 21 or the top side rod 31. The waist side rod 21 and the top side rod 31 are respectively provided with first screw holes 211 and third screw holes 311 for screwing the first locking bolts 42. After the first locking bolts 42 pass through the limiting plates 41, they are screwed to the first screw holes 211 on the waist side rod 21 and the third screw holes 311 on the top side rod 31, respectively, to firmly fix the foot pedal 4 to the corresponding side rods. The installation and removal of the foot pedal 4 can be completed by a simple screwing method, which is convenient and quick to operate and improves construction efficiency.

[0026] Specifically, the two ends of the cantilever pole 6 are equipped with a second locking bolt 61 and a third locking bolt 62, respectively. The second locking bolt 61 passes through one end of the cantilever pole 6 and is screwed to the intermediate frame 2. The third locking bolt 62 passes through the other end of the cantilever pole 6 and is screwed to the side of the foot pedal 4. The foot pedal 4 has a fourth screw hole 43 on both sides without the limiting plate 41 for screwing the third locking bolt 62. The intermediate frame 2 has a second screw hole 24 for screwing the second locking bolt 61. The second screw hole 24 provides a fixing point for the second locking bolt 61 on the intermediate frame 2, and the fourth screw hole 43 provides a fixing point for the third locking bolt 62 on the foot pedal 4, ensuring that the cantilever pole 6 can stably connect the intermediate frame 2 and the foot pedal 4.

[0027] Furthermore, the top side rod 31 is fixedly installed on the top frame handrail 3 by a detachable structure. The detachable structure includes locking blocks 312 fixedly connected to the bottom of both ends of the top side rod 31 and locking frames 32 fixedly connected to the top frame handrail 3 and corresponding to the locking blocks 312 for insertion of the locking blocks 312. The locking blocks 312 at both ends of the top side rod 31 can be inserted into the locking frames 32 on the top frame handrail 3, realizing the detachable connection between the top side rod 31 and the top frame handrail 3. The detachable structure makes it easy to remove the top side rod 31 from the top frame handrail 3, which facilitates the transportation and storage of the construction frame and saves space.

[0028] Furthermore, the crossbars on both sides of the top frame handrail 3 are covered with sleeves 33; the sleeves 33 cover the crossbars on both sides of the top frame handrail 3, providing a comfortable grip for construction workers and providing soft contact when touching the ceiling.

[0029] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
