Abstract
Description
Technical Field
[0001] This utility model relates to the field of scaffolding technology, specifically to an auxiliary device for building construction scaffolding. Background Technology
[0002] Cantilever scaffolding refers to scaffolding whose structure is unloaded from rigid cantilever beams (frames) attached to the building structure. It is used for main structure or decoration work in building construction and for safety protection needs. Each section of scaffolding must not exceed 24 meters in height. The permissible erection height for a single cantilever scaffold is 20 meters. The building structure to which the cantilever scaffolding is attached must be a reinforced concrete or steel structure, and must not be attached to a brick-concrete or stone structure. The supporting structure of the cantilever scaffolding should be a cantilever beam or cantilever truss made of steel, and steel pipes are not permitted; its joints should be bolted or welded, and fasteners are not permitted. The fixing method to the building structure should be determined through design calculations. It is suitable for reinforced concrete and steel structures, high-rise or super high-rise buildings, for main structure or decoration work in building construction and for safety protection needs.
[0003] The uprights on cantilever scaffolding are usually welded to structural steel. This method results in higher labor costs and also makes it impossible to adjust the installation position of the uprights, affecting their reusability.
[0004] Based on this, the present invention designs an auxiliary device for building construction scaffolding to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide an auxiliary device for building construction scaffolding, in order to solve the problem mentioned in the background art that the uprights of the current cantilever scaffolding are usually welded to the steel profile. This method results in high labor costs and, on the other hand, the welding method makes it impossible to adjust the installation position of the uprights, which affects the reuse.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction scaffolding auxiliary device, comprising a steel profile installed on a concrete structure using multiple U-shaped screws, a limiting plate being fitted on two vertical sections of the U-shaped screws, the limiting plate abutting against the top surface of the steel profile, a nut being threaded onto each of the two vertical sections, the lower end face of the nut abutting against the top surface of the limiting plate, a vertical pole being installed at the end of the steel profile away from the U-shaped screws, a mounting seat being slidably connected to the steel profile, the mounting seat being connected to the steel profile using multiple first bolts, a first waist-shaped groove being provided on the steel profile for the first bolts to move freely, a driving structure being provided on the steel profile for driving the mounting seat to move horizontally, an insertion hole being provided on the mounting seat for the lower end of the vertical pole to be inserted, and a second bolt being threaded horizontally through the vertical pole, and a through hole being provided on the vertical pole for one end of the second bolt to be inserted into the mounting seat.
[0007] Preferably, the driving structure includes an ear block fixed to the profile steel, a driving screw threaded through the ear block horizontally, and one end of the driving screw extending out of the ear block being rotatably connected to the mounting base.
[0008] Preferably, the mounting base has a protrusion, and a locking block with a circular longitudinal section is coaxially fixed to the drive screw. The protrusion has a locking groove for the locking block to engage and for free rotation.
[0009] Preferably, a rotating ring is fitted at the upper end of each of the two vertical sections, and a connecting sleeve is fixedly connected to the rotating ring. A drive shaft is connected between the two connecting sleeves. Each end of the drive shaft is provided with a threaded portion in the length direction. The threads of the two threaded portions are opposite in direction, and the two threaded portions are threaded through the two connecting sleeves respectively.
[0010] Preferably, the limiting plate has a second waist-shaped groove that allows the vertical section to move freely.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by sliding the mounting base on the steel profile and using the first bolt to limit the mounting base, the installation position of the upright on the steel profile can be adjusted and it is easy to recycle. By setting a driving structure, the mounting base can be driven to move horizontally more conveniently. By setting a rotating ring, connecting sleeve and driving shaft, the driving shaft rotates, so that the two vertical sections can be pulled together, thereby pressing the vertical sections against the outer wall of the steel profile wing plate, thus stably limiting the position of the steel profile.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4This utility model provides a technical solution: a construction scaffolding auxiliary device, comprising a steel section 6 installed on a concrete structure using multiple U-shaped screws 1, a limiting plate 2 commonly fitted on two vertical sections of the U-shaped screws 1, the limiting plate 2 abutting against the top surface of the steel section 6, a nut 3 threaded onto each of the two vertical sections, the lower end face of the nut 3 abutting against the top surface of the limiting plate 2, a rotating ring 4 fitted onto the upper end of each of the two vertical sections, a connecting sleeve 5 fixedly connected to the rotating ring 4, a drive shaft commonly connected between the two connecting sleeves 5, and threaded portions 13 at both ends of the drive shaft along its length, the threads of the two threaded portions 13 having opposite directions, and the two threaded portions 13 respectively threaded through the two connecting sleeves 5. To tighten the two vertical sections so that they press against the outer wall of the wing plate of the steel section 6, first use an external tool to rotate the drive shaft. The two threaded parts 13 on the drive shaft engage with the two connecting sleeves 5 respectively. Since the threads of the two threaded parts 13 are in opposite directions, the two connecting sleeves 5 move relative to each other, tightening the two vertical sections so that they press against the outer wall of the wing plate of the steel section 6, preventing the steel section 6 from shifting and affecting the safety of the scaffolding. The limiting plate 2 has a second waist-shaped groove 14 that allows the vertical section to move freely, so that the vertical section is not interfered with by the limiting plate 2 when moving. The end of the steel section 6 away from the U-shaped screw 1 is equipped with a vertical pole 11, and the steel section 6 is slidably connected to a mounting bracket. Mounting base 9 is connected to steel section 6 by multiple first bolts 8. Steel section 6 has a first oblong groove 15 for the first bolts 8 to move freely. Steel section 6 has a drive structure for driving the horizontal movement of mounting base 9. The drive structure includes an ear block 10 fixed to steel section 6, with a drive screw 12 threaded horizontally through the ear block 10. Mounting base 9 has a protrusion 16. A circular-section locking block 17 is coaxially fixed to the drive screw 12. The protrusion 16 has a rotatable groove 18 for the locking block 17 to engage. The locking block 17 rotates and is limited within the groove 18, allowing the drive screw 12 to be rotatably connected to the mounting base 9. (The last sentence appears to be incomplete and possibly refers to adjusting the position.) When positioning the pole 11, first loosen the first bolt 8, then use an external tool to rotate the drive screw 12, so that the drive screw 12 is threaded onto the lug 10. Since the drive screw 12 is rotatably connected to the mounting base 9, it can drive the mounting base 9 to move horizontally. After it moves into place, tighten the first bolt 8, and then firmly install the mounting base 9 on the steel profile, thereby adjusting the installation position of the pole 11. The mounting base 9 has an insertion hole for the lower end of the pole 11 to be inserted, and a second bolt 7 is threaded through it horizontally. The pole 11 has a through hole for the second bolt 7 to be inserted into the mounting base 9. By inserting the second bolt 7 into the through hole, the pole 11 is installed in the mounting base 9.
