Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically to building component scaffolding, specifically a mobile building scaffolding that is easy to assemble and disassemble. Background Technology

[0002] During the construction and pouring of concrete structural components, scaffolding is required as a working platform. Traditional scaffolding is mainly composed of a large number of loose parts (steel pipes, couplers, scaffold boards, etc.). Installation and dismantling require a lot of manual labor to connect, fasten, and dismantle each part. Although it can meet the needs of building various spatial shapes, the assembly and dismantling process is not only labor-intensive and inefficient, but also requires a high level of technical skill from the operators. Improper operation can easily affect the structural stability or leave safety hazards. When frequent relocation of work positions or short-term, small-scale operations are required, this inefficient assembly and dismantling method seriously restricts the construction progress. Summary of the Invention

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1:

[0049] like Figures 1-11 As shown, this embodiment of the invention provides an easily detachable and mobile construction scaffold for providing a working platform for construction workers in construction projects, especially for temporary operations during construction. Specifically, it includes two symmetrically arranged three-bar components 1 and a footboard.

[0050] The three-bar assembly 1 includes a central bar 101, a first side bar 103, and a second side bar 104. All three bars are steel pipe structures, providing sufficient support. Universal wheels are fixedly installed at the bottom of each bar. Figure 10As shown in the figure, a first universal wheel 102 is fixedly installed at the bottom of the middle rod column 101, a second universal wheel 105 is fixedly installed at the bottom of the first side rod column 103, and a third universal wheel 106 is fixedly installed at the bottom of the second side rod column 104. When the three-rod assembly 1 is in use (in a vertical state), it can rely on the universal wheels to form on the ground, realizing the movable function. A cross beam frame 1016 is fixedly connected to the side of the middle rod column 101. The cross beam frame 1016 is a rectangular frame structure and needs to provide a large tensile force. One end of the cross beam frame 1016 far from the middle rod column 101 is fixedly connected with a mounting plate 1017. A plurality of through holes are provided on the mounting plate 1017 to facilitate the fixation of the two mounting plates 1017 by a bolt group. A first cross bar 1011 is fixedly connected to the side of the first side rod column 103. One end of the first cross bar 1011 far from the first side rod column 103 is rotatably installed on the middle rod column 101. A second cross bar 107 is fixedly connected to the side of the second side rod column 104. One end of the second cross bar 107 far from the second side rod column 104 is rotatably installed on the middle rod column 101.

[0051] By designing the structure of the above three-rod assembly 1, it can present a state as shown in Figure 11 the figure, that is, the first side rod column 103 and the second side rod column 104 are folded and overlapped, making the three-rod assembly 1 present a gantry structure, which is convenient for loading and transportation.

[0052] The two mounting plates 1017 corresponding to the two three-rod assemblies 1 are fixedly installed, and generally 8 groups of high-strength bolts are used for fixed installation; as shown in Figure 2 the figure, the two first side rod columns 103 corresponding to the two three-rod assemblies 1 are fixedly connected by a first cross frame 2. Generally, the first cross frame 2 and the first side rod column 103 are fixedly installed together by a U-shaped frame, and the two second side rod columns 104 corresponding to the two three-rod assemblies 1 are fixedly connected by a first cross frame 2. The second side rod column 104 and the first cross frame 2 are fixedly installed together by a U-shaped frame.

[0053] According to the above installation method, the middle rod column 101, the first side rod column 103, and the second side rod column 104 corresponding to the two three-rod assemblies 1 are distributed in a "day" shape. Then, a tread board is installed on the top of the two three-rod assemblies 1 distributed in a "day" shape. The tread board is used for operators to stack tools, building materials, and as a personnel working platform.

[0054] In this application, by designing the three-rod assembly 1, its first side rod column 103 and second side rod column 104 are folded and overlapped, making the three-rod assembly 1 present a gantry structure, which is convenient for loading and transportation; moreover, after the mounting plates 1017 of the two groups of three-rod assemblies 1 are butt-jointed and fixed, a mobile construction scaffolding can be formed after simple arrangement and installation of the first cross frame 2 and the tread board. Its assembly process is very simple. During the actual use process, it can reduce the workload of scaffolding erection and disassembly and improve work efficiency.

[0055] In one embodiment, each three-bar assembly 1 is provided with two sets of first crossbars 1011 and two sets of second crossbars 107, which are used to increase the stability of the connection between the first side bar 103, the second side bar 104 and the middle bar 101. The two sets of second crossbars 107 are located inside the two sets of first crossbars 1011. There are two sets of crossbeam frames 1016. The two sets of first crossbars 1011 are located inside the two sets of crossbeam frames 1016. The lower crossbeam frame 1016 directly supports the first crossbar 1011 and the second crossbar 107. One end of the first crossbar 1011 far from the first side bar 103 is fixedly connected with a first sleeve 1014. The first sleeve 1014 is sleeved on the middle bar 101, and the first sleeve 1014 and the middle bar 101 are rotatably installed. One end of the second crossbar 107 far from the second side bar 104 is fixedly connected with a second sleeve 1013. The second sleeve 1013 is sleeved on the middle bar 101, and the second sleeve 1013 and the middle bar 101 are rotatably installed. A stabilizing sleeve 108 is fixedly connected to the middle bar 101 and between the two sets of second sleeves 1013. The top of the stabilizing sleeve 108 supports the upper first crossbar 1011 and second crossbar 107.

[0056] As Figure 10 shown, the lower crossbeam frame 1016 supports the lower first sleeve 1014, and the bottom end of the stabilizing sleeve 108 restricts the lower second sleeve 1013, so that the lower first sleeve 1014 and second sleeve 1013 are both relatively stable; the top end of the stabilizing sleeve 108 supports the upper first sleeve 1014, and the upper crossbeam frame 1016 restricts the upper second sleeve 1013, so that the upper first sleeve 1014 and second sleeve 1013 are both relatively stable, making the entire three-bar assembly 1 relatively stable.

[0057] When assembled into a disassemblable and movable construction scaffolding in the shape of a "day" character as Figure 2 shown, it is necessary to keep the middle bar 101, the first side bar 103 and the second side bar 104 in the three-bar assembly 1 on the same straight line. For this purpose, the following structure is designed in this application: Another side of the first sleeve 1014 is fixedly connected with a short section 1012 parallel to the first crossbar 1011. An installation piece 1010 is fixedly connected to the end of the stabilizing sleeve 108. The short section 1012, the second crossbar 107 and the installation piece 1010 are fixedly installed through a U-shaped locking piece 1015. In this way, the second crossbar 107 and the first crossbar 1011 are always kept on a straight line, and the second crossbar 107, the first crossbar 1011 and the middle bar 101 are fixed together (the purpose is to keep the second crossbar 107, the first crossbar 1011 perpendicular to the crossbeam frame 1016).

[0058] In one embodiment, in order to increase the stability of the two three-bar components 1 after connection, lugs 109 are fixedly connected to the sides of the stabilizing sleeve 108 near both ends; a tie rod assembly 7 is connected between the two stabilizing sleeves 108 corresponding to the two three-bar components 1. The tie rod assembly 7 includes two tie rods that are distributed in a cross pattern. The ends of the tie rods are movably installed with the lugs 109, and the cross parts of the tie rods are also rotatably connected by pins.

[0059] In one embodiment, the footboard is a second platform 5, which includes two sets of parallel second crossbeams 502 and several planks 501. A limiting block 1018 is fixedly connected to the top of the upper crossbeam 1016. A notch is formed between the limiting block 1018 and the intermediate column 101. The second crossbeams 502 are located inside the notch, and both ends of the second crossbeams 502 are fixedly installed with the first side column 103 and the second side column 104, respectively. The two sets of parallel second crossbeams 502 provide a support frame, and the planks 501 are clipped onto the two sets of parallel second crossbeams 502.

[0060] Specifically, the plank 501 includes: two sets of parallel angle steel cross members 5011, hook members 5012, and cross plate members 5013. Both ends of the angle steel cross members 5011 are fixedly connected to hook members 5012. The hook members 5012 correspond to the second cross frame 502 and can be hung on the second cross frame 502. Several cross plate members 5013 perpendicular to the angle steel cross members 5011 are fixedly connected between the two sets of parallel angle steel cross members 5011. Several cross plate members 5013 provide support surfaces for the angle steel cross members 5011.

[0061] In one embodiment, in order to add a platform for temporarily placing building materials, multiple first crossbeams 2 are provided, and the end of the uppermost first crossbeam 2 extends outward to form a long frame 2a, on which a suspension platform assembly 6 is installed.

[0062] In actual use, some building materials are placed on the suspended platform assembly 6, and then personnel transfer the building materials from the suspended platform assembly 6 to the platform at the top of the easily disassembled and mobile building scaffold, thus forming a two-layer structure, which is more convenient to use.

[0063] Specifically, the suspended platform assembly 6 includes: two sets of parallel first angle steels 601, two sets of parallel second angle steels 602, several T-shaped frames 604, a central beam 605, and suspension steel wires 603.

[0064] Two sets of first angle steels 601 and two sets of second angle steels 602 are fixedly connected to form a rectangular frame. Suspension steel wires 603 are fixedly connected to the outer side of the second angle steels 602. The other end of the suspension steel wires 603 is fixedly connected to the long frame 2a. Several T-shaped frames 604 are fixedly connected between the two sets of first angle steels 601. A central beam 605 is fixedly connected between the two sets of second angle steels 602. The central beam 605 is fixedly connected to several T-shaped frames 604. The central beam 605 is used to increase the strength of the T-shaped frames 604.

[0065] Example 2:

[0066] like Figures 10-12 As shown, this embodiment of the invention provides an easily detachable and assembleable mobile construction scaffold for providing a working platform for construction workers in construction projects, especially for temporary operations during construction. Specifically, it includes two symmetrically arranged three-bar components 1 and a footboard.

[0067] The three-bar assembly 1 includes a central bar 101, a first side bar 103, and a second side bar 104. All three bars are steel pipe structures, providing sufficient support. Universal wheels are fixedly installed at the bottom of each bar. Figure 10 As shown, a first caster wheel 102 is fixedly installed at the bottom of the middle rod 101, a second caster wheel 105 is fixedly installed at the bottom of the first side rod 103, and a third caster wheel 106 is fixedly installed at the bottom of the second side rod 104. This allows the three-bar assembly 1 to be movable when in use (in a vertical position) by relying on the caster wheels to form a stable position on the ground. A crossbeam frame 1016 is fixedly connected to the side of the middle rod 101. The crossbeam frame 1016 is a rectangular frame structure that needs to provide a large tensile force. The crossbeam frame 1016 is located away from the middle rod. One end of the pole 101 is fixedly connected to a mounting plate 1017. The mounting plate 1017 has several through holes to facilitate the fixing of two mounting plates 1017 with bolts. The side of the first side pole 103 is fixedly connected to a first crossbar 1011. The end of the first crossbar 1011 away from the first side pole 103 is rotatably installed with the middle pole 101. The side of the second side pole 104 is fixedly connected to a second crossbar 107. The end of the second crossbar 107 away from the second side pole 104 is rotatably installed with the middle pole 101.

[0068] By designing the above-mentioned three-bar component 1 structure, it can present the following: Figure 11 The state shown is such that the first side rod 103 and the second side rod 104 are folded and overlapped, so that the three-bar assembly 1 presents a gantry structure, which is convenient for loading and transportation.

[0069] The two mounting plates 1017 corresponding to the two three-bar components 1 are fixedly installed, generally using 8 sets of high-strength bolts; the two first side rods 103 corresponding to the two three-bar components 1 are directly fixedly connected through the connecting sleeve 3, and the two second side rods 104 corresponding to the two three-bar components 1 are fixedly connected through the connecting sleeve 3, such as... Figure 12 As shown: the middle rod 101, the first side rod 103, and the second side rod 104 corresponding to the two three-bar components 1 are distributed in a rhombus shape, and the foot plate is a rhombus-shaped first platform 4. The two ends of a diagonal line on the foot plate are respectively fixedly installed with two connecting sleeves 3.

[0070] In some smaller spaces, two three-bar components 1 can be used to erect a diamond-shaped scaffold, and a diamond-shaped first platform 4 can be provided.

[0071] Specifically, a limiting block 1018 is fixedly connected to the top of the upper crossbeam 1016. The limiting block 1018 is located in the limiting opening reserved on the first plate 4. The limiting block 1018 is used to limit the first plate 4 and prevent the first plate 4 from sliding.

[0072] In practical use, the connection methods of the two three-bar components 1 in Embodiment 1 and Embodiment 2 can also be combined to form a structure with one side being triangular and the other side being square, thereby adapting to different space usage needs.

[0073] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
