Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a novel scaffolding wall connecting piece. Background Art

[0002] Wall ties are an important part of scaffolding. Many cases of scaffolding collapse accidents at home and abroad are caused by improper setting of wall ties or failure to replace them in time after the wall ties were removed. Scaffolding instability is usually divided into overall instability and local instability. Among them, overall instability is the main form of damage caused by scaffolding instability. The damage is caused by the lack of lateral stiffness of wall ties or a transverse frame with a large initial curvature. Wall ties that are reasonably set, have high bearing capacity, and meet the requirements of the structure can play a direct role in improving the calculated span of the calculation unit and increasing the lateral stiffness, and thus play an important role in the overall stability of the scaffolding.

For example, during the later scaffolding dismantling process, workers need to cooperate in filling holes, and there is a risk of water seepage in the holes of the external wall scaffolding. Therefore, the existing technology needs to be improved. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 , the utility model provides a technical solution:

[0021] In the present technical solution, a novel scaffolding wall connecting member comprises a steel plate 2 and a steel pipe 1, wherein the steel pipe 1 is welded to the lower end of the side wall of the steel plate 2, and a connecting hole 3 is provided at the upper end of the side wall of the steel plate 2. A screw rod 5 is assembled inside the connecting hole 3, and the outside of the screw rod 5 is located on one side of the steel plate 2 and is screwed with a nut a7, and the outside of the screw rod 5 is located on the other side of the steel plate 2 and is screwed with a nut b4. An anti-slip groove 8 is provided at the end of the screw rod 5, and an anti-slip groove 8 is screwed with an anti-slip rod 10 inside the anti-slip groove 8. The outer wall of the screw rod 5 is located on the right side of the nut b4 and is provided with four slots 11, which are connected to the anti-slip groove 8. The angle between each two adjacent slots 11 is 45°. After the anti-slip rod 10 is screwed into the anti-slip groove 8, the end of the screw rod 5 is supported, and the supporting angle of the screw 5 is 25°.

[0022] This technical solution consists of five parts: ordinary steel pipes, steel plates, screws, nuts a, nuts b, and plastic protective sleeves. During the erection of the scaffolding, the wall connecting parts between the frame and the main structure are generally pre-buried short steel pipes on the beams of the main structure. After the concrete pouring is completed and solidified, they are connected to the scaffolding; or after the concrete pouring is completed and the frame column formwork is removed, the frame and the frame column are connected. This uses a lot of materials, and the steel pipes pre-buried in the structural beams cause material waste; there are many scaffolding holes that need to be left during the construction of the masonry project, especially masonry workers often remove the wall connecting parts privately to facilitate their work, causing safety hazards; in the later stage of the scaffolding dismantling process, masonry workers are also required to cooperate with scaffold workers to seal the scaffolding holes reserved in the wall. The density of the scaffolding eye sealing is also poor, and water seepage often occurs in the scaffolding holes on the exterior wall. The present invention first uses a 5mm thick steel plate with a size of 60*100mm, opens a connecting hole φ18 in the middle at 1 / 4 of the long side, and then welds the steel plate to one end of a φ48*3.0 steel pipe with a length of 1.2 meters. The welding is offset, and the φ18 hole is exposed to pass the screw to form an integral wall connecting tool. The reinforcement nut a and the nut b fall on the screw 5, and an anti-slip groove 8 is provided at the bottom end of the screw 5. The anti-slip rod 10 is screwed in, and the screw 5 divided into four parts by the groove 11 is propped open to prevent the nut b4 from loosening.

[0023] In some technical solutions, the inner wall of the anti-slip groove 8 is provided with a reverse internal thread 12, and the outer wall of the anti-slip rod 10 is provided with a reverse external thread 16, and the reverse external thread 16 and the reverse internal thread 12 cooperate with each other.

[0024] In this technical solution, the anti-drop rod 10 is an expansion bolt in the prior art.

[0025] In some technical solutions, the end of the anti-drop rod 10 is installed on the driving disk 9, and a cross groove is provided on the side wall of the driving disk 9.

[0026] In this technical solution, it is convenient to rotate the anti-drop rod 10 and to operate it with a screwdriver.

[0027] In some technical solutions, the four slots 11 formed on the screw 5 are inclined and distributed in a fan shape, and the inclination angle between the short side and the long side of the slot 11 is 5°.

[0028] In this technical solution, the provided slots 11 can not only prop up the screw rod 5 to prevent the nut b4 from loosening, but also avoid causing damage to the screw rod 5.

[0029] In some technical solutions, a fixing ring 17 is fixedly installed on the outer upper end of the screw 5 , and an annular pressing plate 13 , a spring 18 and an annular rubber sheet 15 are sheathed on the circumferential surface of the screw 5 .

[0030] In this technical solution, when the screw 5 is rotated, the annular rubber sheet 15 slides upward due to the action of the screw hole. As the screw is further screwed, the annular rubber sheet 15 contacts the fixing ring 17. The annular rubber sheet 15 is deformed due to the action of the fixing ring 17, sealing the screw hole. The spring 18 is located on the upper side of the annular pressing sheet 14, so that the annular pressing sheet 14 is squeezed downward due to the action of the spring 18. The extrusion block 13 is squeezed downward due to the action of the annular pressing sheet 14, so that the extrusion block 13 further squeezes the edge of the annular rubber sheet 15, thereby improving the sealing effect. The annular pressing sheet 14 is located on the upper side of the fixing ring 17, the spring 18 is located on the upper side of the annular pressing sheet 14, the annular rubber sheet 15 is located on the lower side of the fixing ring 17, and the extrusion block 13 is fixedly installed at the lower end edge of the annular pressing sheet 14.

[0031] In some technical solutions, a plastic protective sleeve 6 is sheathed on the outside of the screw rod 5 and the nut a7.

[0032] In this technical solution, the plastic protective sleeve is wrapped to prevent concrete from being injected into the nut a.

[0033] Working principle: Before pouring the main concrete, the nuts are embedded in the structural beams and wrapped with plastic protective sleeves to prevent concrete from being injected into the nuts. After the concrete solidifies, the beam formwork is removed to expose the nut holes. The steel pipe 1 of the integral wall connection is fixed to the inner and outer uprights of the scaffolding, and the steel plate 2 is pressed tightly against the structural beam. The φ18 hole is aligned with the embedded nut hole, and then the φ16 screw 5 is inserted to rigidly fix the wall connection and the embedded nut to complete the connection of the wall connection. This wall connection can effectively ensure the rigid connection between the scaffolding frame and the main structure, and effectively ensure the stability and safety of the frame. When the frame is dismantled, the φ16 screw is unscrewed, the wall connection and the structural beam are separated, and the nut hole can be sealed during the exterior wall surface decoration. This nut hole is a non-through hole, which can effectively prevent rainwater from the exterior wall from seeping into the room. This wall connection can be recycled to reduce the loss of tempered material.
