Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and in particular to a matching component for a disc buckle frame body armpit angle and overhanging position. BACKGROUND

[0002] In the field of building construction, disc buckle scaffolding is widely used due to its many advantages, among which full-disc buckle scaffolding is often used for station frame construction. However, during construction, the frame construction at the armpit angle and overhanging position faces a series of technical problems. In terms of component standards, the current relevant specifications lack clear provisions for frame construction at the armpit angle and overhanging position. This deficiency directly leads to the fact that, during on-site construction, a disc buckle steel pipe is mostly used to reinforce the armpit angle position.

[0003] From the perspective of structural stability and safety, the disc buckle steel pipe reinforcement method has obvious shortcomings. Due to the connection characteristics of the disc buckle steel pipe itself, when subjected to certain external forces, it is prone to loosen and deform, which poses a serious threat to the quality and stability of the entire frame.

[0004] At the same time, for the operation frame platform of the side wall temporary frame, the conventional method is to lay overhanging footboards as a walking channel. This method has many defects in terms of safety and convenience. In terms of safety, the fixing method of the overhanging footboard is relatively simple, and during the worker's walking process, the worker may fall and get injured due to shaking, displacement, etc. In terms of convenience, its width and carrying capacity are limited, which is not conducive to the worker's carrying of tools and materials, and reduces the construction efficiency.

[0005] In summary, the reinforcement of the frame construction at the armpit angle and overhanging position of the disc buckle scaffolding in the prior art is unstable, affecting the quality and safety of the frame. Therefore, based on the above problems, the prior art needs to be improved. CONTENT OF THE INVENTION

[0006] The purpose of the present application is to improve the efficiency and safety of frame construction.

[0007] The above technical purpose of the present application is achieved by the following technical solution: a matching component for a disc buckle frame body armpit angle and overhanging position, comprising a horizontal rod, one end of the horizontal rod being detachably installed on a main body vertical rod, the end of the horizontal rod away from the main body vertical rod being provided with a mounting sleeve for sleeving a protective rail piece; an inclined strut is provided on the mounting sleeve, one end of the inclined strut away from the mounting sleeve being provided on the main body vertical rod.

[0008] By adopting the technical scheme, one end of the horizontal rod is detachably installed on the main body vertical rod, facilitating installation and disassembly, improving construction efficiency, and facilitating flexible adjustment and reuse in different scenes. The installation sleeve at the other end of the horizontal rod can accommodate the guardrail part, providing reliable safety protection for the construction personnel at the armpit and cantilever part, effectively reducing the safety risk in the construction process. The inclined brace arranged on the installation sleeve further enhances the stability of the entire component, enabling the guardrail part to be more firmly installed on the disc buckle frame body, ensuring that it can play a good protective role under various complex construction conditions, thereby providing a strong guarantee for the smooth construction.

[0009] Optionally, a stiffening rod is connected between the horizontal rod and the inclined brace.

[0010] By adopting the technical scheme, the presence of the stiffening rod greatly enhances the structural strength of the entire matching component. At the armpit and cantilever part of the disc buckle frame body, a large stress is often borne, and the stiffening rod effectively shares the pressure borne by the horizontal rod and the inclined brace, making the component more stable and reliable. This not only improves the safety during construction, reduces the potential risks caused by deformation or damage of the component, but also prolongs the service life of the matching component and reduces the maintenance cost. The stiffening rod makes the connection between the horizontal rod and the inclined brace more compact, forming a stable triangular structure, further improving the anti-interference ability of the entire component under complex construction environment, thereby providing a solid guarantee for the smooth construction.

[0011] Optionally, the stiffening rod and the installation sleeve are arranged in parallel.

[0012] By adopting the technical scheme, parallel arrangement makes the entire component more regular in appearance and more reasonable in layout in limited space, avoiding possible space waste and installation interference caused by staggered rod parts. Parallel arrangement helps uniform force transmission. When the armpit and cantilever part of the disc buckle frame body are subjected to external force, the stiffening rod can work cooperatively with the installation sleeve to uniformly disperse the force to each part, reducing local stress concentration, thereby improving the stability and carrying capacity of the entire component. This parallel arrangement also facilitates the operation of the construction personnel during installation and disassembly, making the assembly of the component more convenient and efficient, thereby providing strong support for the smooth progress of the construction schedule.

[0013] Optionally, the horizontal rod is provided with a mounting part at one end close to the main body vertical rod, the mounting part is concave to form a mounting groove, the main body vertical rod is provided with a connecting disc, the connecting disc can be embedded into the mounting groove, the mounting part is hollow to form an installation channel for inserting a plug pin, and the installation channel and the mounting groove are in communication.

[0014] By adopting the above technical scheme, the concave mounting groove in the horizontal rod mounting piece and the connecting disc on the main body vertical rod are mutually embedded, so that the connection between the horizontal rod and the main body vertical rod is more accurate and stable. The connecting disc can be firmly embedded in the mounting groove, effectively preventing the horizontal rod from shaking or shifting during use, and improving the structural stability of the entire disc buckle frame body. The hollow mounting channel in the mounting piece and the design for inserting the mounting pin further enhance the connection strength between the horizontal rod and the main body vertical rod. The use of the pin provides a reliable locking mechanism for the connection, ensuring that the horizontal rod is tightly connected to the main body vertical rod under various external forces, greatly improving the safety during construction. The connection method is simple to operate, facilitating installation and disassembly by construction personnel, improving work efficiency, and reducing construction cost.

[0015] Optionally, one end of the diagonal brace close to the main body vertical rod is provided with an abutting piece, and the abutting piece is concavely provided with an abutting groove, and the main body vertical rod can be embedded in the abutting groove.

[0016] By adopting the above technical scheme, the abutting piece at one end of the diagonal brace is concavely provided with an abutting groove, and the main body vertical rod can be embedded therein, so that the connection between the diagonal brace and the main body vertical rod is more tight and stable. At the axillary angle and overhanging part of the disc buckle frame body, the diagonal brace bears a large lateral force, and the embedded connection can effectively prevent the diagonal brace from shifting or slipping when under stress, ensuring that the diagonal brace can always play its supporting role, thereby enhancing the stability of the entire frame body at special parts. The embedded design of the abutting groove and the main body vertical rod makes the installation process more convenient and efficient. Construction personnel only need to align the main body vertical rod with the abutting groove and embed it, without the need for complex adjustment and fixing operations, greatly saving installation time and labor cost. It is convenient for later maintenance and disassembly, improving the flexibility of the disc buckle frame body.

[0017] Optionally, the mounting sleeve is provided with a disc buckle, and the disc buckle is provided with a through hole for inserting the pin.

[0018] By adopting the above technical scheme, the disc buckle on the mounting sleeve allows two of the matching components to be assembled together, greatly enhancing the adaptability and flexibility of the disc buckle frame body at the axillary angle and overhanging part. In actual construction, multiple matching components can be combined and installed according to different engineering needs and space layouts, thereby better meeting the safety protection and structural support requirements in complex construction environments. The design of the disc buckle facilitates transportation and storage. In the unused state, multiple matching components can be disassembled into smaller parts for transportation, reducing the occupied space and transportation cost. At the construction site, construction personnel can quickly assemble according to the actual situation, improving the construction efficiency. At the same time, the disc buckle connection method is simple and reliable, ensuring the overall stability and safety after assembly.

[0019] Optionally, the through hole is provided with a plurality of through holes.

[0020] By adopting the above technical scheme, when the two disc buckle frame body armpit angles and overhanging positions need to be assembled with each other by using the matching components, the plurality of through holes provide more connection options. The connection position can be adjusted according to actual needs, so that the assembly is more flexible and variable, and different installation angles and space requirements can be adapted. The plurality of through holes also increase the stability of the connection. By selecting the through holes at different positions for the bayonet connection, the stress of the connection position can be dispersed, and local excessive stress can be prevented. In actual use, if a through hole is worn or damaged, other through holes can be selected, thereby prolonging the service life of the matching components and reducing maintenance costs.

[0021] Optionally, the mounting sleeve is provided with a threaded structure.

[0022] By adopting the above technical scheme, the threaded structure makes the connection between the protective barrier and the mounting sleeve more stable. At the armpit angles and overhanging positions of the disc buckle frame body, various external forces may act on the protective barrier, and the threaded connection can effectively prevent the protective barrier from loosening or slipping, thereby providing more reliable protection for construction safety. The threaded structure is convenient to install and disassemble. Construction personnel can easily install or disassemble the protective barrier on the mounting sleeve by rotating the protective barrier, thereby improving work efficiency. The threaded structure also has a self-locking function. As the protective barrier is screwed in, the connection becomes tighter and tighter, thereby reducing the risk of loosening caused by accidental collisions and the like.

[0023] In summary, the present application at least has the following beneficial effects:

[0024] 1. By providing a mounting sleeve at one end of the horizontal rod and matching with the inclined brace, the armpit angles and overhanging positions of the disc buckle frame body can be efficiently and conveniently reinforced, thereby improving the construction efficiency compared with the traditional fastener steel pipe method;

[0025] 2. The design of the inclined brace on the mounting sleeve enhances the stability and safety of the overall structure, thereby effectively reducing the safety hazards in the construction process;

[0026] 3. The detachable installation design between the horizontal rod and the main body vertical rod facilitates quick assembly and disassembly, thereby improving the construction convenience and safety. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0031] The application will be further described in detail below with reference to the accompanying drawings.

[0032] In this embodiment, with reference to Figs. 1-2 A matching component for the corner and overhanging part of a disc buckle frame body, comprising a crossbar 1, one end of the crossbar 1 being detachably mounted on a main body vertical rod 2, the end of the crossbar 1 away from the main body vertical rod 2 being provided with a mounting sleeve 3 for sleeving a guardrail component 4; the mounting sleeve 3 is provided with a diagonal brace 5, one end of the diagonal brace 5 away from the mounting sleeve 3 being arranged on the main body vertical rod 2, thereby effectively improving the construction efficiency and ensuring the work safety.

[0033] Specifically, the crossbar 1 is usually made of alloy steel pipe, having good strength and load-bearing capacity, and being able to reduce the overall weight while ensuring the structural strength, so as to make the installation more convenient. The crossbar 1 can also adopt a reinforcing rib structure to enhance the overall rigidity of the crossbar 1. The reinforcing rib structure can be a multi-directional plate structure, which not only increases the strength of the crossbar 1, but also reduces the material cost.

[0034] The mounting sleeve 3 is usually made of steel pipe, and is provided with a threaded structure 16 inside to facilitate connection with other components. The design of the mounting sleeve 3 can be changed according to actual needs. The threaded structure 16 inside the mounting sleeve 3 enables the mounting sleeve 3 to be threadedly connected with the guardrail component 4. Not only can the stable installation of the guardrail component 4 be ensured, but also the mounting sleeve 3 can be conveniently disassembled and reused. The mounting sleeve 3 can also be made of high-strength steel plate, and its cross section can be square or circular, with the specific size being adjusted according to actual needs. The crossbar 1 and the mounting sleeve 3 are fixedly connected by welding, so as to ensure the stability and durability of the structure.

[0035] One end of the diagonal brace 5 is connected with the mounting sleeve 3, and the other end is connected with the main body vertical rod 2, so as to form a triangular structure. The connection between the diagonal brace 5 and the mounting sleeve 3 can be achieved by welding or threaded connection. One end of the diagonal brace 5 is provided with an abutting component 12, and the abutting component 12 is provided with an inner recessed abutting groove 13, and the main body vertical rod 2 is embedded in the abutting groove 13 to form a stable connection. The inclination angle of the diagonal brace 5 can be adjusted according to actual installation needs, for example, the inclination angle is set to be between 30° and 60°, so as to ensure the stability and load-bearing capacity. Preferably, additional reinforcing rings can be arranged at both ends of the diagonal brace 5 to increase the stability of the overall structure. The reinforcing rings can be made of steel plates with a thickness of 3 mm and are fixedly connected with the diagonal brace 5 by welding.

[0036] Embodiment 2

[0037] Specifically, referring to Figs. 1-2 , the cross bar 1 and the inclined brace 5 are connected with a stiffener 6, which can be made of steel pipe or steel plate. One end of the stiffener 6 is welded and fixed with the cross bar 1, and the other end is welded and fixed with the inclined brace 5. It can effectively improve the stability and carrying capacity of the overall structure. Preferably, the stiffener 6 and the mounting sleeve 3 are arranged in parallel, which is more regular and orderly during installation and use. Parallel arrangement not only looks more beautiful in appearance, but also helps to uniformly transmit force. When the disc buckle 14 frame body bears external force, the stiffener 6 can work cooperatively with the cross bar 1 and the inclined brace 5 to uniformly disperse the force to each part, avoiding local stress concentration. For example, when the disc buckle 14 frame body is subjected to lateral wind load or vibration during construction at the armpit angle and cantilever position, the stiffener 6 can effectively enhance the stability and carrying capacity of the overall structure, preventing the cross bar 1 and the inclined brace 5 from deforming or being damaged. In actual construction, construction personnel can select appropriate stiffener 6 materials and sizes according to specific engineering requirements and site conditions. For parts bearing larger load, steel plates with larger thickness or steel pipes with larger diameter can be selected as stiffeners 6 to improve the strength and stability of the overall structure. At the same time, during welding, the welding process specification must be strictly followed to ensure the welding quality and avoid welding defects affecting the performance and service life of the stiffener 6. By using the stiffener 6 made of steel pipe or steel plate, and welding one end of the stiffener 6 with the cross bar 1 and the other end with the inclined brace 5, as well as arranging the stiffener 6 and the mounting sleeve 3 in parallel, the overall structural stability and carrying capacity of the matching components for the armpit angle and cantilever position of the disc buckle 14 frame body can be significantly improved, providing strong guarantee for construction safety and engineering quality.

[0038] Embodiment 3

[0039] Specifically, referring to Figs. 1-2 , the cross bar 1 is provided with a mounting piece 7 near one end of the main vertical rod 2, the mounting piece 7 is concave to form a mounting groove 8, the main vertical rod 2 is provided with a connecting disc 9, the connecting disc 9 can be embedded into the mounting groove 8, the mounting piece 7 is hollow to form a mounting channel 10 for inserting a bolt 11, and the mounting channel 10 and the mounting groove 8 are communicated.

[0040] In practical applications, the horizontal rod 1 is first installed near one end of the main vertical rod 2. The design of the mounting part 7 makes the installation process more convenient and stable. The concave mounting groove 8 in the mounting part 7 cooperates with the connecting disc 9 on the main vertical rod 2. The connecting disc 9 can be precisely fitted into the mounting groove 8, ensuring the accurate and relative fixation of the horizontal rod 1 and the main vertical rod 2 in the horizontal direction. After the connecting disc 9 is embedded in the mounting groove 8, the insertion pin 11 is inserted through the hollow installation channel 10 in the mounting part 7. The design of the installation channel 10 being in communication with the mounting groove 8 allows the insertion pin 11 to smoothly pass through the installation channel 10 and enter the mounting groove 8, thereby locking the connecting disc 9. The insertion operation of the insertion pin 11 is simple and convenient, and can quickly achieve the firm connection of the horizontal rod 1 and the main vertical rod 2. When selecting the insertion pin 11, different materials and specifications of the insertion pin 11 can be selected according to actual needs to ensure the strength and stability of the connection. At the same time, in order to improve the installation efficiency, marks or guide structures can be provided on the mounting part 7 to facilitate the construction personnel to accurately find the position of the installation channel 10, and ensure that the insertion pin 11 can be smoothly inserted.

[0041] In the disassembly process, the insertion pin 11 is only pulled out of the installation channel 10, and the connection between the horizontal rod 1 and the main vertical rod 2 is released, which is convenient and fast. This detachable connection makes the disc buckle 14 frame body more flexible and convenient during transportation, storage and assembly, and can adapt to different construction scenes and needs. Through the cooperation of the mounting part 7, the mounting groove 8, the connecting disc 9 and the insertion pin 11, reliable connection of the horizontal rod 1 and the main vertical rod 2 is achieved, which provides a strong guarantee for the stable use of the disc buckle 14 frame body armpit and cantilever part with matching components.

[0042] Embodiment 4

[0043] Specifically, referring to Figs. 1-2 , the inclined support 5 is provided with an abutting part 12 at one end close to the main vertical rod 2, and the abutting part 12 is concavely provided with an abutting groove 13, and the main vertical rod 2 can be fitted into the abutting groove 13. In the actual production and installation process, the abutting part 12 at one end of the inclined support 5 close to the main vertical rod 2 needs to be carefully designed and processed. The concave abutting groove 13 in the abutting part 12 should be accurately matched according to the size of the main vertical rod 2 to ensure that the main vertical rod 2 can be closely fitted into the abutting groove 13. First, when making the abutting part 12, high-strength metal materials can be used to form through casting, forging or mechanical processing. The shape and size of the abutting groove 13 should be strictly controlled to match the shape of the main vertical rod 2, so as to achieve good fitting effect. At the same time, in order to increase the strength and stability of the abutting part 12, reinforcing ribs can be provided on the abutting part 12 or the abutting part 12 can be designed to be thickened.

[0044] In the installation of the diagonal brace 5, the main vertical rod 2 is aligned with the abutting groove 13 of the abutting piece 12, and then slowly embedded into the groove. In order to ensure the firmness of the embedding, anti-skid lines can be provided on the inner wall of the abutting groove 13 or a material with high friction coefficient can be used to increase the friction between the main vertical rod 2 and the abutting groove 13. Once the main vertical rod 2 is embedded into the abutting groove 13, the connection between the diagonal brace 5 and the main vertical rod 2 can be further strengthened by welding, bolting or other fixing methods. For example, a plurality of bolt holes can be provided around the abutting piece 12, and the abutting piece 12 and the main vertical rod 2 are firmly connected together by bolts. During actual use, the connection part of the diagonal brace 5 and the main vertical rod 2, especially the abutting groove 13 of the abutting piece 12, should be regularly checked to ensure that the main vertical rod 2 is always tightly embedded in the abutting groove 13 without loosening or displacement. If problems are found, the abutting piece 12 should be repaired or replaced in time to ensure the stability and safety of the carabiner 14 frame.

[0045] Embodiment 5

[0046] Specifically, referring to Figs. 1-2 , the mounting sleeve 3 is provided with a carabiner 14, and the carabiner 14 is provided with a through hole 15 for inserting the bolt 11. Preferably, the through hole 15 is provided with a plurality of through holes. The carabiner 14 on the mounting sleeve 3 allows two such matching components to be assembled together, greatly enhancing the adaptability and flexibility of the carabiner 14 frame in the armpit and cantilever positions. In actual construction, multiple matching components can be combined and installed according to different engineering needs and space layouts, thereby better meeting the safety protection and structural support requirements in complex construction environments. The design of being able to be assembled facilitates transportation and storage. In the unused state, multiple matching components can be disassembled into smaller parts for transportation, reducing the occupied space and transportation cost. At the construction site, construction personnel can quickly assemble according to the actual situation, improving the construction efficiency. At the same time, the connection mode of the carabiner 14 is simple and reliable, ensuring the overall stability and safety after assembly.

[0047] The carabiner 14 on the mounting sleeve 3 is made of high-strength metal material and is fixed on the mounting sleeve 3 by precise welding or mechanical connection. The through hole 15 provided on the carabiner 14 is used for inserting the bolt 11, and the position and size of these through holes 15 should be reasonably arranged according to the actual use requirements. When the through hole 15 is provided with a plurality of through holes, more choices can be provided for installation and connection. In the actual installation process, construction personnel can select appropriate through holes 15 for bolt 11 insertion according to different installation angles and needs. When using the bolt 11 for connection, the material of the bolt 11 should also have sufficient strength and hardness to ensure the firmness of the connection. The bolt 11 can be made of steel or other high-strength alloy materials, and its surface can be treated to prevent rust to prolong the service life.

[0048] Example 6

[0049] Specifically, referring to Figs. 1-2 , the mounting sleeve 3 is provided with a threaded structure 16. When manufacturing the mounting sleeve 3, an advanced processing technology is used to process the threaded structure 16 on the inner wall of the sleeve. The accuracy and quality of the thread can be ensured by mechanical processing methods such as turning and thread rolling.

[0050] The pitch and depth of the thread should be reasonably designed according to the size of the guardrail member 4 and the required connection strength. Generally speaking, the pitch should not be too large or too small to ensure that the guardrail member 4 can be smoothly rotated and firmly connected. The depth of the thread should be sufficient to provide sufficient friction and stability. When installing the guardrail member 4, align one end of the guardrail member 4 with the opening of the mounting sleeve 3, and then slowly rotate the guardrail member 4 to make it rotate into the mounting sleeve 3. Due to the action of the thread, the guardrail member 4 will gradually be closely combined with the mounting sleeve 3. During the rotation process, a certain torque can be appropriately applied to ensure the tightness of the connection. In order to further enhance the stability of the connection, after the guardrail member 4 is rotated into the mounting sleeve 3, a locking nut or other fixing device can be used for reinforcement. The locking nut can be rotated on the guardrail member 4 and tightly fit with the end of the mounting sleeve 3 to prevent the guardrail member 4 from loosening during use. During actual use, the threaded structure 16 in the mounting sleeve 3 and the connection of the guardrail member 4 should be checked regularly. If the thread is damaged or the guardrail member 4 shows signs of loosening, it should be repaired or replaced in time. At the same time, when installing and disassembling the guardrail member 4, attention should be paid to the operation specification to avoid damaging the threaded structure 16 by excessive force or improper tools.

[0051] The embodiments of the specific implementation are the preferred embodiments of the present application, and are not limited to the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
