Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a scaffold for building construction. Background Technology

[0002] In the process of building construction, scaffolding is a key piece of equipment that supports construction workers to carry out high-altitude operations. The storage platform used to place construction tools and building materials is a core component that directly affects work efficiency and operational safety. Construction workers need to frequently access tools and replenish materials. A well-organized and flexibly adjustable storage space can effectively reduce ineffective labor and lower the risk of material transfer during high-altitude operations.

[0003] Existing scaffolding platforms are mostly fixed structures, allowing materials to be placed only in fixed locations. When the work location changes, materials must either be repeatedly moved manually, increasing physical exertion and wasting time; or the scaffolding must be disassembled and moved to adjust the placement position, which is cumbersome and can easily damage the stability of the scaffolding, making it difficult to meet the construction requirements of "convenient material placement and flexible repositioning". In view of this, we propose a new type of scaffolding for building construction. Utility Model Content

[0004] The purpose of this utility model is to provide a scaffold for building construction to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a scaffolding for building construction, comprising:

[0006] Four horizontal bars are arranged in a square shape. Vertical bars are symmetrically fixed on both sides of each horizontal bar, and the four vertical bars are arranged in a square shape in the vertical direction. Multiple longitudinal bars that are linearly and equally spaced are fixedly installed between the two vertical bars on the left and right sides.

[0007] Two guide rods are fixedly installed between two vertical rods on the same layer, and a shelf is provided directly above the two guide rods.

[0008] A moving mechanism is provided, located directly below the shelf, and is used to control the shelf to slide laterally on two guide rods.

[0009] Preferably, a foot pad is fixedly installed at the bottom end of the vertical rod.

[0010] Preferably, a diagonal brace is fixedly installed between the two vertical bars on the front and rear sides, and the two diagonal braces are arranged in a cross pattern.

[0011] Preferably, a reinforcing rib is fixedly installed at the connection between the vertical rod and the longitudinal rod.

[0012] Preferably, the upper surface of the shelf is provided with an anti-slip layer.

[0013] Preferably, the moving mechanism includes:

[0014] Four sets of sliding components are symmetrically arranged and slidably mounted on the guide rods. Each sliding component consists of two vertically symmetrical C-shaped support rods and movable components fixedly mounted on both sides of the C-shaped support rods. An L-shaped support rod is fixedly installed between the two C-shaped support rods on the same side, and the shelf is fixedly installed between the two L-shaped support rods located above.

[0015] Preferably, the moving component includes:

[0016] A fixed base is fixedly installed at the end of a C-shaped strut. Three fixed blocks are fixedly installed on the outer wall of the fixed base in a circularly evenly spaced manner. A rotating shaft is fixedly installed on the fixed blocks, and a roller sleeve is rotatably installed on the rotating shaft.

[0017] Preferably, the fixing block is symmetrically provided with extrusion blocks on both sides, the extrusion blocks cover the upper surface of the fixing block, and the extrusion blocks are fixed to the fixing seat by bolts.

[0018] The beneficial effects of this utility model are:

[0019] This scaffolding for building construction uses a moving mechanism in conjunction with a storage board. The storage board can neatly place tools and auxiliary materials, solving the problem of scattered placement. The moving mechanism can drive the storage board to slide smoothly along the guide rod, allowing items to be moved horizontally with the work position without moving materials or scaffolding. This solves the pain point of "difficulty in moving items" of traditional fixed platforms, and the stable sliding prevents items from falling. It combines convenience and safety, effectively improving construction efficiency. Attached Figure Description

[0028] Example 1:

[0029] This embodiment provides a scaffold for building construction, including:

[0030] Four horizontal bars 1 are arranged in a square shape. Vertical bars 2 are symmetrically fixed on both sides of the horizontal bars 1. The four vertical bars 2 are arranged in a square shape in the vertical direction. Multiple longitudinal bars 3 are fixedly installed between the two vertical bars 2 on the left and right sides in a linear and equally spaced manner.

[0031] Two guide rods 7 are fixedly installed between two vertical rods 3 on the same layer, and a shelf 8 is provided directly above the two guide rods 7.

[0032] A moving mechanism is located directly below the shelf 8 and is used to control the shelf 8 to slide laterally on the two guide rods 7.

[0033] In this embodiment, the moving mechanism includes:

[0034] Four sets of sliding components are symmetrically arranged and slidably installed on the guide rod 7. Each sliding component consists of two vertically symmetrical C-shaped support rods 9 and a movable component fixedly installed on both sides of the C-shaped support rods 9. An L-shaped support rod 10 is fixedly installed between the two C-shaped support rods 9 on the same side. The shelf 8 is fixedly installed between the two L-shaped support rods 10 located above.

[0035] In this embodiment, the moving component includes:

[0036] The fixed seat 11 is fixedly installed at the end of the C-shaped support rod 9. Three fixed blocks 12 are fixedly installed on the outer wall of the fixed seat 11 in a circumferentially evenly distributed manner. A rotating shaft 14 is fixedly installed on the fixed block 12, and a roller sleeve 15 is rotatably installed on the rotating shaft 14.

[0037] In this embodiment, pressing blocks 13 are symmetrically arranged on both sides of the fixing block 12. The pressing blocks 13 cover the upper surface of the fixing block 12 and are fixed to the fixing seat 11 by bolts.

[0038] The four horizontal bars 1 are made of Q235B grade hot-rolled steel pipes with an outer diameter of 50mm and a wall thickness of 3.5mm. The ends of two adjacent horizontal bars 1 are welded and fixed by right-angle connectors (unmarked) to form a U-shaped frame with a side length of 2.5m, ensuring the rigidity of the overall horizontal support foundation. The horizontal bars 1 are fixed to the vertical bars 2 on both sides by full welding, with a weld height of not less than 3mm. The number of vertical bars 2 on each side is set to 3 longitudinal bars, which are evenly distributed along the length of the horizontal bars 1, and the vertical spacing between adjacent vertical bars 2 is 1.The 8m height meets the height requirements for personnel operation during building construction. The longitudinal rods 3 between the left and right vertical rods 2 are also made of Q235B grade steel pipe, with an outer diameter of 40mm and a wall thickness of 3mm. Both ends of the longitudinal rods 3 are fixed to the vertical rods 2 via sleeve connectors (unmarked), with a sleeve length of 80mm, reinforced by spot welding. The spacing of the longitudinal rods 3 is 600mm, ensuring stable support for the guide rods 7 while reducing material usage. The two guide rods 7 are set parallel, with their axes perpendicular to the axes of the longitudinal rods 3. Both ends of the guide rods 7 are bolted to the longitudinal rods 3 via flanges (unmarked). The flange hole diameter matches the bolt specifications, and the bolt tightening torque is controlled at 45-50 N·m to ensure stable support between the guide rods 7 and the longitudinal rods 3. Rod 3 has no relative displacement; the shelf 8 is made of 5mm thick Q235 steel plate, and its length and width dimensions are adapted to the spacing between the two guide rods 7 and the length of the longitudinal rod 3, respectively. The lower surface of the shelf 8 is fixed to the two upper L-shaped support rods 10 by welding. The weld seam is continuously distributed along the length of the L-shaped support rod 10, and the weld leg size is 4mm; in the four sets of sliding components of the moving mechanism, the two C-shaped support rods 9 of each set of sliding components symmetrically clamp the guide rod 7 from top to bottom. The C-shaped support rod 9 is made of C-shaped channel steel (opening towards the guide rod 7). The channel width of the channel steel is 2-3mm larger than the outer diameter of the guide rod 7 to ensure that the C-shaped support rod 9 can slide smoothly along the guide rod 7 without obvious shaking; in the moving components on both sides of the C-shaped support rod 9, the fixed seat 11 is made of cast iron. The iron frame is integrally formed, with its inner diameter interference-fitted with the outer diameter of the C-shaped support rod 9. After assembly, it is tightened and fixed by radial M10 bolts to prevent axial movement between the fixing seat 11 and the C-shaped support rod 9. Three fixing blocks 12 are evenly distributed along the circumference of the fixing seat 11, with a central angle of 120° between adjacent fixing blocks 12. The fixing blocks 12 are made of rectangular steel plates (8mm thick, 50mm long and 30mm wide). One end of the fixing block 12 is welded to the fixing seat 11, and the weld length covers the width of the fixing block 12. The rotating shaft 14 is a U-shaped steel plate (6mm thick), with its open end welded to the other end of the fixing block 12. The width of the U-shaped groove is 1mm larger than the outer diameter of the roller sleeve 15. The roller sleeve 15 is made of wear-resistant cast iron. The cylindrical sleeve is manufactured with an inner diameter that is clearance-fitted to the pin (unmarked) of the rotating shaft 14. The pin has a diameter of 12mm and a length extending 5mm beyond each side of the rotating shaft 14. Both ends of the pin are limited by cotter pins (unmarked) to prevent the roller sleeve 15 from detaching from the rotating shaft 14. The pressing block 13 is an arc-shaped steel plate (the arc is consistent with the outer circle of the fixing seat 11, and the thickness is 5mm). Through holes (11mm diameter) are opened at both ends of 13 to match the pre-set threaded holes of 11. Bolts are passed through the through holes and tightened to the fixing seat 11. The pressing block 13 covers the welded area between the fixing block 12 and the fixing seat 11, preventing corrosion of the welded area and enhancing the bending resistance of the fixing block 12, thus preventing deformation of the fixing block 12 when the roller sleeve 15 is under stress.

[0039] Example 2:

[0040] This embodiment provides a scaffold for building construction. In addition to the technical solution of the above embodiment, it also has the following technical features: 2 has 4 fixedly installed at its bottom end.

[0041] Among them, foot pad 4 is made of nitrile rubber (Shore hardness 60-70HA), which combines wear resistance and elasticity. The overall structure of foot pad 4 is cylindrical (diameter 100mm, height 50mm), and the top has a cylindrical groove that matches the bottom of the vertical rod 2 (groove depth 20mm, diameter interference fit with the outer diameter of the vertical rod 2). The inner wall of the groove is coated with epoxy resin adhesive to enhance the bonding strength between foot pad 4 and vertical rod 2. The bottom of foot pad 4 has diamond-shaped anti-slip texture (texture depth 2mm, spacing 5mm) to increase the coefficient of friction with the ground and prevent the scaffolding from slipping due to external forces during construction. For construction scenarios with uneven ground, the bottom of foot pad 4... It can be replaced with an adjustable structure (unnumbered) – that is, a threaded sleeve is added above the rubber base, and the sleeve is threaded to the bottom end of the vertical rod 2. The height of the vertical rod 2 can be adjusted by rotating the sleeve to keep the top of the four vertical rods 2 horizontal. The adjustment range is 0-30mm. In addition to adhesive bonding, the foot pad 4 can also be fixed to the vertical rod 2 by opening an annular groove at the bottom end of the vertical rod 2. The inner wall of the groove of the foot pad 4 is provided with a limiting protrusion (matching the annular groove). During assembly, the protrusion is inserted into the annular groove to form a mechanical limit and prevent the foot pad 4 from falling off the vertical rod 2. In addition, the side wall of the foot pad 4 is provided with a drainage hole (5mm in diameter) to prevent rainwater from accumulating between the foot pad 4 and the ground and to prevent the foot pad 4 from aging and cracking after long-term soaking.

[0042] Example 3:

[0043] This embodiment provides a scaffold for building construction. In addition to the technical solution of the above embodiment, it also has the following technical features: diagonal braces 5 are fixedly installed between the two vertical bars 2 on the front and rear sides, and the two diagonal braces 5 are arranged in a cross pattern.

[0044] The diagonal brace 5 is made of Q235B grade steel pipe (outer diameter 50mm, wall thickness 3.5mm) of the same specification as the vertical brace 2. The intersection angle of the two diagonal braces 5 is set at 60°. At this angle, the shear and tensile performance of the diagonal brace 5 is optimal, which can distribute the lateral load of the scaffolding to the greatest extent. The two ends of the diagonal brace 5 are fixed to the vertical brace 2 by clamp connectors (unmarked). The clamp consists of two semi-circular steel plates (thickness 6mm). The inner diameter of the clamp is adapted to the outer diameter of the vertical brace 2. The two clamps are tightened with M14 bolts. The tightening torque of the bolts is controlled at 60-65 N·m to ensure that there is no relative rotation between the clamp and the vertical brace 2. A cross-shaped connector (unmarked) is provided at the intersection of the two diagonal braces 5. The connector is made of four steel plates welded into a cross structure. Each steel plate has an arc-shaped groove that matches the outer diameter of the diagonal brace 5. The inner wall of the arc-shaped groove is covered with a rubber pad (2mm thick), which can not only avoid rigid collision between the diagonal brace 5 and the connector, but also enhance the stability of the intersection point. For scaffolding with a height of more than 6m, a set of diagonal braces 5 must be set between every two layers of vertical bars 2, and the intersection direction of the upper and lower layers of diagonal braces 5 is staggered (60° for the upper layer and 120° for the lower layer) to form a three-dimensional anti-lateral displacement system. The surface of the diagonal brace 5 is coated with the same anti-rust paint as the vertical bars 2 (epoxy zinc-rich primer + alkyd topcoat) to ensure that the corrosion rate of the diagonal brace 5 and the vertical bars 2 is the same, thus extending the service life of the overall scaffolding.

[0045] Example 4:

[0046] This embodiment provides a scaffold for building construction. In addition to the technical solution of the above embodiment, it also has the following technical features: a reinforcing rib 6 is fixedly installed at the connection between the vertical bar 2 and the longitudinal bar 3.

[0047] Among them, the reinforcing rib 6 is made of Q345 high-strength steel plate (10mm thick), with an overall shape of a right triangle. The lengths of the right-angled sides are 100mm and 80mm respectively, and the hypotenuse is rounded (radius 5mm) to prevent personnel from being injured by bumps during construction. The two right-angled sides of the reinforcing rib 6 are respectively attached to the vertical rod 2 and the longitudinal rod 3. The contact surface is coated with welding anti-spatter agent, and then fixed by fillet weld. The weld height is 6mm, and the weld length covers the entire length of the right-angled sides. After welding, the weld is subjected to flaw detection (penetration test) to ensure that there are no defects such as porosity and cracks. At the connection between the vertical rod 2 and the longitudinal rod 3, the number of reinforcing ribs 6 is set to 2 for the vertical rod, respectively. Symmetrically installed on both sides of the connection node between vertical rod 2 and longitudinal rod 3, forming a bidirectional stress dispersion structure, dispersing the concentrated stress at the node to the main structure of vertical rod 2 and longitudinal rod 3; weight-reducing holes (15mm in diameter) are opened on the surface of the reinforcing rib 6 to reduce the amount of material used without reducing strength. The center of the weight-reducing hole is 30mm away from the right-angle vertex of the reinforcing rib 6 to avoid weakening the strength of the weld; for vertical rod 2 or longitudinal rod 3 with a diameter greater than 50mm, the length of the right-angle side of the reinforcing rib 6 needs to be increased proportionally (for every 10mm increase in diameter, the length of the right-angle side increases by 20mm) to ensure that the reinforcing rib 6 can effectively cover the connection node and play a sufficient strengthening role.

[0048] Example 5:

[0049] This embodiment provides a scaffold for building construction. In addition to the technical solution of the above embodiment, it also has the following technical features: the upper surface of 8 is provided with an anti-slip layer.

[0050] The anti-slip layer is made of EPDM rubber (4mm thick), which is oil-resistant, aging-resistant, and resistant to high and low temperatures (-40℃ to 80℃), making it suitable for the complex environment of building construction. The anti-slip layer is fully covered on the upper surface of the shelf 8, with the coverage area matching the upper surface area of ​​the shelf 8. The edges of the anti-slip layer are aligned with the edges of the shelf 8 to avoid steps. The anti-slip layer is fixed to the shelf 8 using a dual method of "adhesion + mechanical fixing"—first, neoprene rubber adhesive is applied to the upper surface of the shelf 8, and after the anti-slip layer is applied, pressure is applied (0.5MPa, pressure held for 12 hours) to ensure a firm bond; then, through holes (8mm diameter) are made around the perimeter and at 300mm intervals in the middle of the anti-slip layer. The anti-slip layer is fixed to the shelf 8 using countersunk bolts (M8). The head of the countersunk bolt is 1mm lower than the surface of the anti-slip layer to prevent people from tripping when stepping on it. The upper surface of the anti-slip layer has raised strip patterns (2mm high, 5mm wide, and 10mm apart). The pattern direction is consistent with the length direction of the shelf 8. This can increase the friction between the soles of people's shoes and the anti-slip layer, and guide rainwater to flow along the pattern to both sides of the shelf 8 (the sides of the shelf 8 have drainage grooves, which are not labeled). In addition, the anti-slip layer can be cut into different shapes according to construction needs. For areas on the shelf 8 where tools need to be placed, thickened anti-slip blocks (6mm thick) can be added at the corresponding positions to further enhance the stability of tool placement and prevent tools from slipping.

[0051] Working principle:

[0052] Before construction, the four horizontal bars 1 are assembled into a U-shaped horizontal frame using right-angle connectors. Then, the top of the vertical bars 2 is welded and fixed to both sides of the horizontal bars 1 to ensure that the four vertical bars 2 are distributed vertically in a U-shape. Subsequently, longitudinal bars 3 are installed between the left and right vertical bars 2, fixed with sleeve connectors and reinforced by spot welding. The number of layers of longitudinal bars 3 is determined according to the construction height. Guide bars 7 are installed between the two longitudinal bars 3 on the same layer and fixed with flanges and M12 high-strength bolts to ensure that the guide bars 7 are parallel and horizontal.

[0053] Next, assemble the moving mechanism: symmetrically clamp the C-shaped support rods 9 onto the guide rods 7, connect the fixed base 11 to the end of the C-shaped support rods 9, install the fixed block 12, rotating shaft 14, and roller sleeve 15 on the fixed base 11, and use the pressing block 13 to cover the connection between the fixed block 12 and the fixed base 11 with bolts. Then, connect the upper and lower C-shaped support rods 9 into a whole using L-shaped support rods 10. Finally, weld the shelf 8 between the two upper L-shaped support rods 10. After that, install foot pads 4 at the bottom of the vertical rods 2, and adjust the height of the foot pads 4 according to the flatness of the ground to ensure that the scaffolding is level. Install cross diagonal braces 5 between the front and rear vertical rods 2 and fix them with clamp connectors. Install reinforcing ribs 6 at the connection between the vertical rods 2 and the longitudinal rods 3, and strengthen the joint by welding. Finally, lay an anti-slip layer on the upper surface of the shelf 8 and fix it with both adhesive and countersunk bolts. During construction, personnel can stand on the platform 8 to operate. By pushing the platform 8, the roller sleeve 15 of the moving mechanism rolls along the guide rod 7, causing the platform 8 to slide laterally, eliminating the need to frequently move the entire scaffold. The anti-slip layer prevents personnel from slipping, the diagonal brace 5 and the reinforcing rib 6 ensure the stability of the scaffold under stress, and the foot pad 4 prevents the scaffold from slipping. The overall structure meets the safety and convenience requirements of building construction.
