Description

TECHNICAL FIELD

[0001] The utility model relates to building construction equipment technical field, concretely is a safe and stable component for building outer wall scaffold. BACKGROUND

[0002] In modern building construction, the outer wall scaffold is a key temporary facility to ensure the safety of construction personnel and provide an operating platform, and its safety and stability are crucial. The safety and stability component of the utility model is designed to meet this demand, aiming to improve the safety and reliability of the outer wall scaffold during construction. With the vigorous development of the construction industry, the scale and height of building construction are increasing, and the requirements for the outer wall scaffold are also increasing. At present, the existing building outer wall scaffold has exposed many problems in actual use, which seriously restricts the safety and efficiency of construction. The stability of the traditional scaffold structure is poor when facing complex and changeable construction environment. For example, in strong wind weather, the scaffold is easily affected by strong wind, leading to increased shaking; during construction, the construction load changes constantly, and when the load distribution is uneven or exceeds the carrying capacity of the scaffold, the scaffold may tilt or even collapse. These safety hazards greatly threaten the safety of construction personnel, and once an accident occurs, it will cause irreparable loss.

[0003] The structure design of the existing part of the safety and stability component is too complex, containing numerous cumbersome parts and connection methods. This makes it necessary to spend a lot of time and labor during installation and disassembly, not only increasing the construction cost, but also reducing the construction efficiency. Moreover, the complex structure increases the operation difficulty of construction personnel, requiring higher professional skills, further limiting its application in actual construction.

[0004] Different types and specifications of scaffolds exist widely in the market, but some existing safety and stability components are difficult to adapt to them. They often can only be applied to scaffolds of specific types or specifications, and cannot meet the diversified construction needs, which greatly limits their application range and increases the difficulties of construction units in selecting and using safety and stability components.

[0005] In summary, it is urgent to develop a building outer wall scaffold safety and stability component with simple structure, convenient installation, safety and stability, and strong universality, which has important practical significance for improving the safety and efficiency of building construction.

[0011] Support column, the support column selects cylindrical steel pipe material, which has good compression and bending resistance, and is vertically welded to the upper surface of the base.The upper end of the support column is provided with a first threaded segment, a first through hole and a second through hole.The first threaded segment is used for threadedly connecting with the cross bar, and the height of the cross bar on the support column can be adjusted by rotating the cross bar to adapt to different construction height requirements.The cross bar is also a cylindrical steel pipe, and both ends thereof are provided with threaded holes matched with the first threaded segment of the upper end of the support column.The internal threads of the inner walls of the threaded holes are tightly matched with the first threaded segment of the support column, and a third through hole is provided at the middle position of the cross bar for hingedly connecting with the diagonal brace.The two ends of the diagonal brace are respectively hingedly connected with the first through hole in the middle of the support column and the third through hole in the middle of the cross bar.The diagonal brace, the support column and the cross bar form a triangular support structure, and the overall stability of the scaffold is effectively enhanced by utilizing the stability principle of the triangle.When subjected to external force, the diagonal brace can decompose the lateral force into vertical and horizontal components to suppress the overturning tendency of the scaffold.

[0012] Connecting device, the connecting device is composed of a connecting sleeve and a bolt.The connecting sleeve is sleeved on the outer side of the support column, and the outer peripheral surface of the connecting sleeve is provided with a plurality of connecting ears, each of which is provided with a non-through insertion hole, and the bolt is fixedly connected with the fourth through hole of the vertical rod or the first through hole of the support column by penetrating the insertion hole on the connecting ear.

[0013] The vertical rod is a cylindrical steel pipe, and the upper end of the vertical rod is provided with a second threaded section and a fifth through hole. The second threaded section can be connected with the threaded hole of the horizontal rod through thread connection, so that the vertical rod and the horizontal rod are stably connected.

Such a tolerance fit not only ensures the tightness of the threaded connection and prevents the horizontal rod from loosening during use, but also facilitates the rapid disassembly and assembly operation of the construction personnel.

[0018] Still further technical solutions, the diameter of the first hinge shaft of the diagonal brace rod is set to be between 12-16 mm, the hinge gap is accurately controlled to be within 0.5 mm, and a self-lubricating bushing is configured. Such a design enables the diagonal brace rod to automatically and flexibly adjust the angle when bearing the load, thereby reducing the response time.

[0019] Still further technical solutions, the inner diameter of the connecting sleeve of the connecting device is greater than the outer diameter of the supporting column, and the fitting gap therebetween is controlled to be between 1-3 mm, so as to ensure that the connecting sleeve can be smoothly sleeved on the supporting column, and meanwhile, excessive shaking is not generated.

[0020] Further technical solutions, the connecting lugs of the connecting device are uniformly distributed in the circumferential direction (the number is 4-8), and the through holes of each connecting lug are provided with elastic washers. Such a design can effectively adapt to the working condition that the verticality deviation of the vertical rod is ±5°, so as to ensure the stability and reliability of the connection.

[0021] (Three) beneficial effects

[0022] Compared with the prior art, the safe and stable assembly of the building outer wall scaffold provided by the utility model has:

[0023] The safe and stable assembly of the utility model mainly consists of base, support column, cross bar, diagonal brace, vertical rod and connecting device and other basic components, and has simple and clear structure. The shape and connecting mode of each component are reasonably designed, facilitating processing and manufacturing. During installation, ordinary construction personnel can complete installation quickly according to the instruction book without using complicated tools and professional technicians, greatly improving installation efficiency and shortening construction time.

[0024] The base is fixed to the ground through anti-skid lines and foundation bolts, effectively preventing the base from sliding during construction and ensuring that the assembly is stable. The triangular stable structure formed by the diagonal brace, the support column and the cross bar can effectively bear external loads such as wind force and construction load. When subjected to external force, the threaded connection and hinged connection of the assembly can be self-adapted according to the actual stress condition, further improving the safety performance and greatly reducing the risk of shaking, tilting and collapse of the scaffold, providing reliable safety protection for construction personnel.

[0025] The connecting sleeve of the connecting device can be sleeved outside the support column with different diameters, and by flexibly adjusting the position and number of bolts, it can adapt to different types and specifications of scaffold vertical rods. This makes the safe and stable assembly have wide applicability and can meet various construction needs, reducing the cost and trouble of construction units due to the need to replace the safe and stable assembly because of different types of scaffolds.

The support column 2 is a cylindrical steel pipe welded to the upper surface of the base 1. The support column 2 has a first threaded section 21 at its upper end and a first through hole 22 and a second through hole 23. The crossbar 3 is also a cylindrical steel pipe with threaded holes 31 at both ends that mate with the first threaded section 21. The first threaded section 21 is threaded through the threaded holes 31, supporting the support column 2 and... The crossbar 3 has a third through hole 32 in the middle; the diagonal brace 4 has a first hinge shaft 41 at each end, one end of the diagonal brace 4 is hinged to the first through hole 22 through the first hinge shaft 41, and the other end is hinged to the third through hole 32 through the first hinge shaft 41; the connecting device 5 includes a connecting sleeve 51 and a bolt 53, the connecting sleeve 51 is sleeved on the outside of the support column 2; the connecting sleeve 51 has a plurality of connecting ears 52 around its perimeter, the connecting ears 52 are used to fix the connection to the first through hole 22 or the fourth through hole 62 through the bolt 53;

[0037] The upright 6 is a cylindrical steel pipe; the end of the upright 6 is provided with a second threaded section 61, and the upright 6 is provided with a fourth through hole 62 and a fifth through hole 64. The second threaded section 61 is connected to the threaded hole 31 by threads; the upright 6 is installed in the connecting lug 52, and the bolt 53 is used to fix the connecting lug 52 to the support column 2 or the upright 6.

[0038] In another embodiment of this utility model, such asFigures 1-6 As shown: the anti-slip texture 11 of the base 1 consists of staggered raised stripes; anchor bolts are inserted into the mounting holes 12 for fixing to the ground; the support column 2 is perpendicular to the base 1, and the welding position of the support column 2 and the base 1 is located at the center of the base 1; the inner wall of the threaded hole 31 is provided with an internal thread that matches the first threaded section 21 of the support column 2, and the threaded drive engagement between the first threaded section 21 and the threaded hole 31 is used to adjust the height of the crossbar 3; the two ends of the diagonal brace 4 are respectively located at the middle of the support column 2 and the crossbar 3, used to form... The structure is a triangular support structure; the inner diameter of the connecting sleeve 51 is greater than the outer diameter of the support column 2, and the connecting lug 52 has a through hole with an elastic washer inside; the bolt 53 is locked to the upright 6 and the support column 2 through the through hole; the upright 6 is also provided with a second hinge shaft 63, which is hinged to the first hinge shaft 41; the support column 2, the crossbar 3, the diagonal brace 4 and the upright 6 are all made of high-strength carbon steel and the surface is galvanized for rust prevention; there are 4-8 connecting lugs 52, which are arranged in an array around the connecting sleeve 51.

[0039] In another embodiment of this utility model, the base 1 includes anti-slip texture 11 and four mounting holes 12. When installing, the base 1 is placed in a predetermined installation position to ensure that the anti-slip texture 11 is in full contact with the ground, so as to give full play to the function of the anti-slip texture and increase the friction between the base and the ground. Anchor bolts are inserted into the ground through the mounting holes 12 at the four corners of the base, and the anchor bolts are tightened with a wrench according to the specified torque to ensure that the base is firmly fixed to the ground and will not shift during subsequent construction.

[0044] The working principle of this utility model patent is as follows: The base's anti-slip texture and anchor bolts provide double fixation to prevent slippage; the support column vertically transfers the load to the ground, and the threaded connection of the crossbar allows for height adjustment; the hinged diagonal brace forms a dynamic triangular structure, decomposing lateral forces into vertical and horizontal components to suppress overturning; the connecting sleeve adapts to different uprights, and stress is dispersed through multi-point bolt fixation. All components work synergistically to optimize the load transfer path, improving resistance to wind loads, eccentric loads, and overall stability.

[0045] After the installation of the safety and stability components is completed, a comprehensive debugging and inspection must be carried out to ensure that the components can function properly. First, carefully inspect the connection points of each component, checking that bolts are tightened, welds are free of cracks, and connections between components are secure, without any loosening or detachment. Second, check the rotational flexibility of the diagonal braces, ensuring they can rotate freely within a certain angle range, and verifying the effectiveness of the triangular stabilizing structure. Finally, conduct a load test on the scaffolding to simulate the load conditions during actual construction, observing the stability and safety of the components under load. If any abnormalities are found, construction should be stopped immediately, and the components adjusted and repaired until they meet the safety requirements for use.
