Description

Technical Field

[0001] The present application relates to the field of scaffolding, and in particular to a scaffolding structure for the construction of the exterior and lower foundation of a building. Background Art

[0002] During the process of repairing the exterior of a building in a building construction project, it is necessary to build a scaffolding on the outside of the wall to facilitate workers to perform high-altitude operations. The conventional operation is to bury the scaffolding directly on the ground outside the house, and then construction can begin.

[0003] During the renovation of a house, not only the outside of the house needs to be strengthened, but also the foundation. The later process of foundation excavation and strengthening will make the scaffolding unstable, thereby reducing the safety of the scaffolding. Utility Model Content

[0004] In order to improve the problem of unstable scaffolding and reduced safety in the use of scaffolding during the later foundation excavation and reinforcement process, the present application provides a scaffolding structure for the construction of the exterior and lower foundation of a building.

[0005] The present application provides a scaffolding structure for building exterior and lower foundation construction using the following technical solutions:

[0006] A scaffolding structure for the construction of the exterior and lower foundation of a building, comprising a frame for climbing operations, and also comprising a support beam group and an installation beam group, wherein the support beam group is laid on the ground and fixedly connected to the wall through a connecting unit, and the installation beam group is fixedly arranged at the bottom of the frame, and a mounting support and an adjustment unit are provided on the support beam group, and the adjustment unit is used to adjust the position of the mounting support on the support beam group and fix the mounting support, and a fixing unit is provided on the mounting support, and the fixing unit is used to fix the mounting beam group on the mounting support.

[0007] By adopting the above technical solution, when installing the scaffolding, the support beam group is first fixedly connected to the wall through the connecting unit, and then the position of the mounting support on the support beam group is adjusted by adjusting the unit body, and then the mounting beam group is placed on the mounting support, and then the mounting beam group is fixed by the fixing unit, thereby improving the connection strength between the bottom of the scaffolding and the wall, improving the stability of the scaffolding during foundation excavation, and improving the safety of the scaffolding.

[0008] In a specific possible implementation scheme, the support beam group includes a plurality of support beams arranged in parallel, and the connection units correspond to the support beams one by one;

[0009] The connection unit comprises a pad and an anchoring screw. The pad is fixedly connected to the support beam. The anchoring screw passes through the pad and is inserted into the wall to fix the pad on the wall.

[0010] By adopting the above technical solution, when fixing the support beam group and the wall, the anchor screw passes through the pad and is inserted into the wall to complete the installation and fixation between the support beam and the wall.

[0011] In a specific feasible implementation scheme, the mounting beam group includes two mounting beams arranged parallel to each other, the number of the mounting supports on each support beam is two and corresponds one-to-one with the mounting beams, and the adjustment unit on each support beam corresponds one-to-one with the mounting support.

[0012] By adopting the above technical solution, when adjusting the position of the mounting support, each adjustment unit adjusts the position of the corresponding mounting support, thereby improving the flexibility of adjusting the positions of the two mounting supports.

[0013] In a specific possible implementation scheme, the adjustment unit includes a support plate and an adjusting screw. The support plate is fixedly arranged on the side of the support beam, the adjusting screw is arranged along the length direction of the support beam and is rotatably connected to the support plate, and the adjusting screw passes through the mounting support and is threadedly connected to the mounting support.

When the adjusting screw stops rotating, the mounting support is in a fixed state, thereby improving the convenience of adjusting the position of the mounting support.

[0015] In a specific possible implementation manner, the adjusting screw passes through another one of the mounting brackets and is slidably connected.

[0016] By adopting the above technical solution, when one adjusting screw drives the mounting support to slide, the mounting support slides along another adjusting screw, thereby improving the sliding stability of the mounting support and the connection strength with the support beam.

[0017] In a specific feasible implementation scheme, the fixing unit includes two base plates, two groups of fasteners and two fixing plates. The mounting beam is an I-beam. The two base plates are fixedly arranged on the mounting support and form a space in the middle for inserting the mounting beam.

The fixing bolt passes through the rotating support block and is threadedly connected to the rotating support block. One end of the fixing bolt is hinged to the fixing plate through a sleeve. The fixing bolt is rotatably connected to the sleeve. Rotating the fixing bolt can push the fixing plate to press the web and lower flange of the mounting beam.

[0020] By adopting the above technical solution, when fixing the mounting beam, the operator screws the fixing bolts, and while the fixing bolts rotate, the fixing plates are pushed through the sleeves to fix the mounting beam on the mounting support. When the fixing plates are fixed, they are pressed against the web and the lower flange of the mounting beam at the same time, thereby improving the stability of the fixing of the mounting beam by the fixing plates.

[0021] In a specific feasible implementation scheme, a rotating shaft is fixedly provided on the rotating support block, the rotating shaft is inserted into the base plate and is rotatably connected, a torsion spring is sleeved on the rotating shaft, one end of the torsion spring is connected to the base plate, and the other end is connected to the rotating support block, and the torsion spring is used to push the fixed plate to abut against the web of the support beam.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The embodiment of the present application discloses a scaffolding structure for the construction of the exterior and lower foundation of a building.

[0034] Reference Figure 1A scaffolding structure for the exterior and lower foundation construction of a building includes a frame 1, a support beam group 2, and an installation beam group 3. The frame 1 is a frame structure formed by splicing a plurality of horizontal bars and longitudinal bars. Workers can climb onto the frame 1 to carry out repair work. The support beam group 2 in this embodiment includes four support beams 21, one end of each support beam 21 is laid on the ground, and the other end is fixedly connected to the wall 5 through a connecting unit 4. The installation beam group 3 in this embodiment includes two installation beams 31, which are arranged in parallel. The bottom of each row of longitudinal bars on the frame 1 is fixedly arranged on the installation beam 31. The installation beam 31 and the support beam 21 in this embodiment are both I-beams. The frame 1 and the wall 5 are fixedly connected by a plurality of connecting rods 11. One end of the connecting rod 11 is fixedly connected to the vertical bar of the frame 1 by a clamp, and the other end is fixedly connected to the wall 5 by an anchor rod, so as to improve the connection strength between the frame 1 and the wall 5.

[0035] Reference Figure 1 Each support beam 21 is provided with a mounting bracket 6 (as shown in the attached Figure 3 ) and the adjustment unit 7, the mounting support 6 and the adjustment unit 7 are in one-to-one correspondence with the mounting beam 31, so that each mounting support 6 can be adjusted in position by an adjustment unit 7, thereby improving the flexibility of position adjustment of the two mounting supports 6. The adjustment unit 7 is used to adjust the position of the mounting support 6 on the support beam 21 and fix the mounting support 6. Each mounting support 6 is provided with a fixing unit 8, and the fixing unit 8 is used to fix the mounting beam 31 on the mounting support 6. The mounting beam 31 and the support beam 21 are arranged in a cross.

[0036] When installing the scaffolding, first lay the support beam 21 on the ground, then fix each support beam 21 to the wall through the connecting unit 4, then adjust the position of the mounting bracket 6 on the support beam 21 through the adjusting unit 7, so that the distance between the two mounting brackets 6 meets the spacing between the two mounting beams 31 on the frame body 1, then place the mounting beam 31 on the mounting bracket 6, and then fix the mounting beam 31 through the fixing unit 8. By fixing the bottom of the scaffolding with the support beam 21, the connection strength between the bottom of the scaffolding and the wall 5 is improved, the stability of the scaffolding during foundation excavation is improved, and the safety of the scaffolding is improved.

[0037] Reference Figure 2 The connection unit 4 in this embodiment includes a pad 41 and an anchor screw 42. The pad 41 is fixedly connected to the support beam 21 by welding. There are multiple anchor screws 42. Multiple anchor screws 42 pass through the pad 41 and are inserted into the wall 5 to fix the pad 41 on the wall 5, thereby completing the installation and fixation between the support beam 21 and the wall 5.

[0038] Reference Figure 3The adjustment unit 7 in this embodiment includes a support plate 71 and an adjustment screw 72. There are two support plates 71. The two support plates 71 are arranged at intervals along the length direction of the support beam 21. Each support plate 71 is located in the groove on the side of the support beam 21 and is fixedly welded to the web, upper flange and lower flange of the support beam 21. The adjustment screw 72 is arranged along the length direction of the support beam 21. The adjustment screw 72 is located in the grooves on both sides of the support beam 21. The two ends of the adjustment screw 72 are respectively inserted into the support plates 71 on the same side and are rotatably connected with the support plates 71. Both ends of the mounting support 6 are fixedly provided with connecting plates 73 inserted into the grooves on both sides of the support beam 21. The connecting plates 73 are slidably arranged with the support beam 21. The adjusting screw 72 is threadedly connected with the connecting plate 73 on the corresponding mounting support 6, and another adjusting screw 72 is slidably connected with another connecting plate 73 on the corresponding mounting support 6. The sliding stability of the mounting support 6 and the connection strength with the support beam 21 are improved.

[0039] When adjusting the position of the mounting support 6, the operator rotates the adjusting screw 72, and the adjusting screw 72 drives the mounting support 6 to slide on the support beam 21 under the support of the support plate 71. When the adjusting screw 72 stops rotating, the mounting support 6 is in a fixed state, thereby improving the convenience of adjusting the position of the mounting support 6.

[0040] Reference Figure 3 , Figure 4 The fixing unit 8 in this embodiment includes two substrates 81, two sets of fasteners 82 and two fixing plates 83. The substrates 81, the fasteners 82 and the fixing plates 83 correspond to each other one by one. The two substrates 81 are fixedly arranged on the mounting support 6 in parallel and at intervals, and a space is formed in the middle for the mounting beam 31 to be inserted. The mounting beam 31 can be inserted between the two substrates 81 and abut against the mounting support 6. The fastener 82 is arranged on the base plate 81. The fastener 82 in this embodiment includes a rotating support block 821 and a fixing bolt 822. A placement slot 84 is opened on the top of each base plate 81. The rotating support block 821 is arranged in the placement slot 84. The opposite sides of the rotating support block 821 are fixed with a rotating shaft 85. The axis of the rotating shaft 85 is perpendicular to the sliding direction of the mounting support 6. The two rotating shafts 85 are inserted into the side wall of the placement slot 84 on the same side and are rotatably connected to the base plate 81. A torsion spring 86 is sleeved on each rotating shaft 85. One end of the torsion spring 86 is fixedly connected to the base plate 81, and the other end is fixedly connected to the rotating support block 821.

[0041] Reference Figure 3 , Figure 5The fixing bolt 822 passes through the rotating support block 821 and is threadedly connected to the rotating support block 821. The two fixing plates 83 are respectively located in the grooves on both sides of the support beam 21 and fit with the web of the support beam 21. The side of the fixing plate 83 away from the web of the support beam 21 is hinged with a sleeve 87, and the sleeve 87 can rotate along the vertical direction. One end of the fixing bolt 822 is inserted into the sleeve 87 and is rotatably connected with the sleeve 87. Rotating the fixing bolt 822 can push the fixing plate 83 to press the web and lower flange of the mounting beam 31. The torsion spring 86 can apply an initial thrust to the rotating support block 821, so that the fixing bolt 822 can push the fixing plate 83 to press against the web of the support beam 21.

[0042] When fixing the mounting beam 31, the mounting beam 31 is inserted between the two base plates 81 and overlapped on the mounting support 6. Then the operator screws the fixing bolt 822. While the fixing bolt 822 rotates, it pushes the fixing plate 83 through the sleeve 87 to fix the mounting beam 31 tightly on the mounting support 6. At the same time, the two fixing plates 83 tighten and fix the web of the support beam 21, thereby completing the fixing of the mounting beam 31 and improving the convenience of installing the mounting beam 31. When the fixing plate 83 is fixed, it is pressed against the web and lower flange of the mounting beam 31 at the same time, thereby improving the stability of the fixing plate 83 fixing the mounting beam 31. The rotating support block 821 is pushed by the torsion spring 86, and the rotating support block 821 pushes the fixing plate 83 to abut against the web of the mounting beam 31 through the fixing bolt 822, thereby improving the stability of the fixing plate 83 and the web of the mounting beam 31, and facilitating the fixing of the fixing plate 83 to the mounting beam 31.

[0043] The implementation principle of a scaffolding structure for the exterior and lower foundation construction of a building in the embodiment of the present application is as follows: when installing the scaffolding, first lay the support beam 21 on the ground, then pass the anchor screw 42 through the pad 41 and insert it into the wall 5 to complete the fixed connection between the support beam 21 and the wall, then rotate the adjusting screw 72, and the adjusting screw 72 drives the mounting support 6 to slide on the support beam 21 under the support of the support plate 71, and adjust the position of the mounting support 6 on the support beam 21 so that the distance between the two mounting supports 6 meets the spacing between the two mounting beams 31 on the frame body 1, and then The mounting beam 31 is placed on the mounting support 6, and then the mounting beam 31 is inserted between the two base plates 81 and overlapped on the mounting support 6. Then the operator screws the fixing bolts 822. While the fixing bolts 822 rotate, they push the fixing plates 83 through the sleeves 87 to fix the mounting beam 31 tightly on the mounting support 6. At the same time, the two fixing plates 83 clamp the webs of the supporting beams 21, thereby completing the fixation of the mounting beam 31, thereby improving the connection strength between the bottom of the scaffolding and the wall 5, improving the stability of the scaffolding during foundation excavation, and improving the safety of the scaffolding.
