Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a combined railing rapid production platform. Background Art

[0002] Currently, there are two ways to produce railings: one is factory-made, and the other is on-site. Factory-made railings require advance customization and cannot be produced and used immediately. On-site production requires the railing steel pipes to be transported to the site. Each railing steel pipe needs to be adjusted and aligned using a spirit level before being welded and fixed (spot welding). After fixing, the horizontality and verticality of each steel pipe need to be checked one by one and adjusted and aligned using a spirit level. After confirmation, the entire piece is welded (full welding). Finally, the horizontality and verticality of each steel pipe are checked as a whole for final adjustment and leveling. Due to the need to repeatedly confirm the size and positioning of each railing section, on-site production takes a long time to complete, the process is complex, and the construction cost is high. It is impossible to achieve the required shortened construction period, which affects the progress of the project. Utility Model Content

[0043] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0044] Example 1:

[0045] This embodiment provides a modular railing rapid production platform for on-site production of railings;

[0046] like Figure 2 As shown, the handrail 4 to be manufactured is a modular handrail, comprising a main crossbar 41, a plurality of railing crossbars 42, and a plurality of railing uprights 43. The main crossbar 41 is the handrail portion of the handrail 4 and has a larger diameter and length than the railing crossbar 42. The plurality of railing uprights 43 are vertically mounted below the main crossbar 41 and spaced apart along the length of the main crossbar 41. The plurality of railing crossbars 42 are evenly spaced apart along the height of the railing uprights 43. The main crossbar 41, railing crossbars 42, and railing uprights 43 are all prefabricated components.

[0047] like Figure 1 As shown, the production platform includes: a frame 1, a braking device, two bases 2 and three limit device groups.

[0048] The frame 1 has a rectangular structure and includes a rectangular frame, a crossbar 11, and a plurality of uprights 12. The long side of the rectangular frame is arranged horizontally. A rotating shaft 13 is mounted on each of the two short sides of the rectangular frame. The two rotating shafts 13 are coaxial, and the axial directions of the two rotating shafts 13 are parallel to the length direction of the rectangular frame. The two ends of the crossbar 11 are respectively fixed to the two short sides of the rectangular frame, and the crossbar 11 is parallel to the long side of the rectangular frame. The two ends of each upright 12 are respectively fixed to the upper long side of the rectangular frame and the crossbar 11, and all uprights 12 are arranged at intervals along the length direction of the rectangular frame. The long side of the rectangular frame connected to the upright 12 is long side a, and the other long side of the rectangular frame is long side b. Each upright 12 is machined with a plurality of limiting grooves along its height direction. The limiting grooves on all uprights 12 correspond one to one along the height direction. The limiting grooves are used to place the railing crossbars 42 of the railing 4 to be manufactured. In this embodiment, the rectangular frame and the skeleton cross bar 11 are made of Q235B model 10 channel steel, and the limiting grooves are located on the two flanges of the channel steel.

[0049] like Figure 1 As shown, the three limit device groups are respectively limit device group a installed on the long side a of the rectangular frame, limit device group b installed on the skeleton cross bar 11, and limit device group c installed on the long side b of the rectangular frame. Limit device group a, limit device group b, and limit device group c are all composed of a plurality of limit devices 3. The limit devices 3 in limit device group a are spaced apart along the length direction of long side a, the limit devices 3 in limit device group b are spaced apart along the length direction of skeleton cross bar 11, and the limit devices 3 in limit device group c are evenly spaced along the direction of long side b. The limit devices 3 in limit device group a and limit device group b correspond one to one, and every two corresponding limit devices 3 are used to fix the two end ends of a railing upright 43. Therefore, the spacing between every two adjacent limit devices 3 in limit device group a and limit device group b is consistent with the spacing between two adjacent railing uprights 43 of the railing 4 to be manufactured. The limit devices 3 on limit device group c are used to fix the large cross bar 41.

[0050] Each limiting device 3 includes: two L-shaped angle steels and a pin. The vertical parts of the two L-shaped angle steels are arranged opposite to each other. The horizontal part of the L-shaped angle steel is fixedly connected to the long side of the rectangular frame or the skeleton cross bar 11, and the vertical part of the L-shaped angle steel is perpendicular to the plane where the rectangular frame is located. A through hole a is processed on the vertical part of the L-shaped angle steel, and the through holes a of the two L-shaped angle steels are coaxial. The two ends of the pin shaft pass through and are installed in the through holes a of the two L-shaped angle steels respectively. In the limiting device group a and the limiting device group b, the spacing between the vertical parts of the two L-shaped angle steels in each limiting device 3 is consistent with the outer diameter of the railing upright 43. The axis of the through hole a of the limiting device 3 is parallel to the length direction of the long side of the rectangular frame. Several railing uprights 43 are placed one by one between the two L-shaped angle steels of the corresponding limiting devices 3, and are locked and fixed by pins (that is, the railing uprights 43 are limited in the space surrounded by the two L-shaped angle steels and the pins. Before fixing the railing uprights 43, it is necessary to first fix the large cross bar 41, then place the railing cross bar 42, and then put the railing uprights 43 between the L-shaped angle steels and fix them. The ends of the railing uprights 43 are against the large cross bar 41 to prevent the railing uprights 43 from falling. The spacing between the vertical parts of the two L-shaped angle steels in each limiting device 3 in the limiting device group c is consistent with the outer diameter of the large cross bar 41. The axis of the through hole a of the limiting device 3 is parallel to the length direction of the short side of the rectangular frame. The large cross bar 41 is placed between the two angle steels of the limiting device 3 in the limiting device group c, and is locked and fixed by pins. The limiting device 3 can provide limiting and support for the large crossbar 41 and the railing uprights 43 of the railing 4, thereby preventing the railing 4 from moving during welding, causing deformation of the railing 4.

[0051] In this embodiment, the L-shaped angle steel in the stopper 3 is made of ∠50x5 equal-leg angle steel. Because the spacing between two adjacent stoppers 3 is determined based on the spacing requirements of the railing uprights 43 of the handrail 4, repeated measurement, adjustment, and alignment are unnecessary. After the railing 4's main crossbar 41, railing crossbars 42, and railing uprights 43 are positioned, spot welding is performed, followed by direct welding. The stopper 3 prevents movement of the railing components during welding, thus preventing deformation of the handrail 4 during welding.

[0052] Two bases 2 are arranged opposite each other on either side of the frame 1. Both bases 2 have an equilateral triangular structure. The two rotating shafts 13 on the rectangular frame of the frame 1 are rotatably mounted on the two bases 2 via bearings. The outer rings of the bearings are fixedly connected to the bases 2, while the inner rings of the bearings are fixedly connected to the rotating shafts 13 of the rectangular frame, enabling the frame 1 to rotate about the axis of the rotating shafts 13. In this embodiment, the bearings are preferably angular contact ball bearings made of 6388 cast steel. The equilateral triangular structure of the bases 2 ensures the stability of the production platform.

[0053] The braking device includes a flange, a braking rod and a braking ring, and is used to brake the frame 1 so that the frame 1 can stop at a set rotation angle.

[0054] The brake ring is fixedly connected to one of the bases 2. The axis of the brake ring is parallel to the axis of the bearing.

[0055] The flange is coaxially fixed to the rotating shaft 13 at the end of the base 2 of the rectangular frame (the base 2 to which the brake ring 4 is fixed). A plurality of through holes b are machined on the flange, and the plurality of through holes b are evenly arranged along the circumference of the flange. The diameter of the through holes b on the flange is the same as the inner diameter of the brake ring. When the flange is rotated until one of the through holes b coincides with the brake ring, the frame 1 is braked by inserting a brake rod through the through hole b on the flange and the brake ring, so that the frame 1 can stop at the set rotation angle, facilitating the welding of the railing 4. In this embodiment, the brake rod is made of a galvanized steel pipe with a diameter of 18 mm.

[0056] In this embodiment, the flange is DN40-PN10, and the inner diameter of the brake ring is 20 mm.

[0057] The production platform in this embodiment draws on the support and rotation methods of old-fashioned popcorn machines. The skeleton 1 can rotate and brake, and can fix, support and limit the railing components (large cross bars, railing uprights and railing cross bars). Through this production platform, the construction period can be shortened by about 30%.

[0058] Example 2:

[0059] This embodiment discloses a modular railing rapid production platform based on the structure of Example 1. The production platform is based on the structure of Example 1. Among the plurality of frame uprights 12, except for the frame uprights 12 located at the two ends, the remaining frame uprights 12 are grouped in pairs, with the two frame uprights 12 in each group mounted on opposite sides of two opposing limit devices 3 in limit device group a and limit device group b, respectively. The spacing between the two frame uprights 12 on either side of the limit device 3 and the limit device 3 is no less than 200 mm, avoiding the weld between the main crossbar 41 and the railing uprights 43.

[0060] Example 3:

[0061] This embodiment discloses a combined railing rapid production platform, based on the structure of embodiment 1. The frame 1 further includes: support poles 14.

[0062] The support rod 14 is located in the middle of the rectangular frame of the frame 1. Its ends are fixedly connected to the two long sides of the rectangular frame, and its shaft is fixedly connected to the frame crossbar 11. The support rod 14 is provided with a retaining groove along its length, which is used to accommodate the railing crossbar 42.

[0063] The length direction of the support rods 14 is parallel to the length direction of the short side of the rectangular frame, which is used to increase the structural strength of the frame 1 and ensure the stability and safety of the production platform.

[0064] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
