Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a coupler for a scaffolding with lugs. Background Art

[0002] During the construction of a building exterior wall, specifically during the construction of the external frame of a steel pipe scaffolding, it is usually necessary to use couplers to connect to the main structure to ensure the stability of the steel pipe external scaffolding. However, in some special node positions, such as bay window balconies and other positions, there may be a retracted structure, resulting in difficulty in connecting the coupler to the external frame. In such positions, there will be parts that require extra-long couplers for connection. If conventional couplers are used for connection, after exceeding a certain length, the stability of the coupler will decrease, and the torsional force of the super-strong coupler will be too large, leading to the coupler falling off or loosening, thus affecting the safety of the external frame structure.

[0003] In summary, there is an urgent need for a coupler that can stably connect the scaffolding to special nodes of the main structure to solve the problems existing in the prior art. Summary of the Utility Model

[0007] A further improvement of the coupler for a scaffolding with lugs of the utility model is that the rod body assembly further includes an adjusting nut, and the adjusting nut is screwed on the first thread.

[0008] A further improvement of the wall connecting member of the scaffolding with ear plates of the present utility model lies in that an adjusting plate is provided on the adjusting nut.

[0009] A further improvement of the wall connecting member of the scaffolding with ear plates of the present utility model lies in that a fastener is provided on the hollow rod.

[0023] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0024] See Figures 1 to 6 As shown, a wall connecting member of a scaffolding with ear plates includes a rod body assembly 1, an ear plate assembly 2 and an embedded component 3. The rod body assembly 1 includes a hollow rod 11. A first thread 12 is provided on the outer periphery of the hollow rod 11, and a second thread is provided on the inner periphery of the hollow rod 11. The embedded component 3 includes a first sleeve 34, an ear plate slot 32, a connecting rod 31 and an embedded plate 33. A third thread is provided on the outer periphery of the connecting rod 31, and the third thread is adapted to the second thread. The connecting rod 31 is coaxially arranged inside the first sleeve 34. The ear plate slot 32 is fixed on the outer periphery of the first sleeve 34 and communicates with the first sleeve 34. The embedded plate 33 is vertically fixed on the first end of the first sleeve 34 and the first end of the connecting rod 31. One end of the ear plate 22 is vertically fixed on the embedded plate 33. The ear plate assembly 2 includes a second sleeve 21 and an ear plate 22. A fourth thread is provided on the inner periphery of the second sleeve 21, and the fourth thread is adapted to the first thread 12. The ear plate 22 is fixed on the outer periphery of the second sleeve 21, and the ear plate 22 is adapted to the ear plate slot 32.

[0025] Specifically, the length of the first thread 12 on the outer periphery of the hollow rod 11 is greater than the sum of the lengths of the first sleeve 34 and the second sleeve 21. The diameter of the connecting rod 31 is smaller than the outer diameter of the hollow rod 11, and the inner diameter of the first sleeve 34 is not less than the outer diameter of the second sleeve 21.

[0026] Preferably, as Figure 3 and Figure 4As shown, the number of the earplate slots 32 is at least two, the number of the earplates 22 is at least two, and the earplates 22 and the earplate slots 32 are arranged in one-to-one correspondence. In this embodiment, the number of the earplate slots 32 is four, and the four earplate slots 32 are arranged in pairs opposite to each other. The number of the earplates 22 is four, and the four earplates 22 are arranged in pairs opposite to each other. The width of the earplate 22 is smaller than the slot width of the earplate slot 32, so that the earplate 22 can be smoothly inserted into the earplate slot 32. Through the insertion arrangement of the earplate 22 and the earplate slot 32, when the hollow rod 11 is inserted into the first sleeve 34 and the second sleeve 21, the situation that the reserved component and the earplate component 2 are twisted and loosened is avoided, and the stability of the device is provided.

[0027] Preferably, as Figure 2 shown, the rod assembly 1 further includes an adjusting nut 13, and the adjusting nut 13 is screwed onto the first thread 12. The adjusting nut 13 can further fix the earplate component 2 to ensure the stability of the hollow rod 11 and the scaffold.

[0028] Preferably, the adjusting nut 13 is provided with adjusting plates. The number of the adjusting plates is two, and the two adjusting plates are arranged opposite to each other, so that the position of the adjusting nut 13 can be adjusted by manually screwing the adjusting plates.

[0029] Preferably, the hollow rod 11 is provided with fasteners 14. Further, the number of the fasteners 14 is at least two, and at least two of the fasteners 14 are fixedly spaced along the axial direction of the hollow rod 11. The fastener 14 is U-shaped and is provided with pins at both ends. The fastener 14 facilitates the fixation of the scaffold members.

[0030] Preferably, the length of the earplate 22 is greater than the length of the earplate slot 32.

[0031] As Figure 5 and Figure 6As shown in the figure, during use, first determine the position of the wall connecting member, measure and lay out the embedding position of the wall connecting member embedding component 3, partially embed the embedding component 3 into the beam structure, and the embedding plate 33 can be welded and fixed with the additional bars in the beam to ensure the stability of the wall connecting member. Subsequently, concrete is poured. After the concrete reaches the strength and the formwork is removed, the wall connecting member is installed. First, partially insert the ear plates 22 into the embedding component 3. The four ear plates 22 on the ear plate component 2 are respectively inserted into the four ear plate slots 32 of the embedding component 3 in a one-to-one docking manner. At this time, the connecting rod 31 in the first sleeve 34 is also inserted into the second sleeve 21 of the ear plate component 2. Since the diameter of the connecting rod 31 is smaller than the inner diameter of the second sleeve 21, the third thread on the connecting rod 31 does not engage with the fourth thread in the second sleeve 21 at this time; because the length of the ear plate 22 is longer than the length of the ear plate slot 32 of the embedded part, a part of the ear plate 22 is still exposed outside the concrete structure after the ear plate 22 is inserted to the bottom. At this time, the rod body component 1 is installed, and the hollow rod 11 is inserted into the second sleeve 21. At this time, the front end of the hollow rod 11 is rotated and inserted, and the first thread 12 on the hollow rod 11 engages with the fourth thread in the second sleeve 21. At this time, continue to rotate the hollow rod 11. When the hollow rod 11 touches the connecting rod 31 in the first sleeve 34, the second thread of the hollow rod 11 engages with the sensitive thread of the connecting rod 31. Rotate the hollow rod 11 until the end of the rod body touches the connecting plate of the embedding component 3 at the bottom. At this time, adjust the adjusting nut 13 on the hollow rod 11, tighten the nut until the nut touches the second sleeve 21, and the wall connecting member is installed as shown in Figure 5 the figure. At this time, the installation of the steel pipe of the wall connecting member and the scaffold can be carried out. The steel pipe is arranged parallel to the hollow rod 11 and is respectively connected with the two fasteners 14 on the hollow rod 11, then the connection and use of the wall connecting member are completed.

[0032] The wall connecting member of the scaffolding with ear plates of the present utility model solves the technical problem that the wall connecting member in the prior art is prone to excessive torque, resulting in the detachment or loosening of the wall connecting member through the insertion connection of the embedding component 3 and the ear plate component 2. The present utility model improves the overall stiffness and anti-torsion and anti-tensile capacity of the wall connecting member, avoids the problem of detachment or loosening of the wall connecting member. At the same time, the double fasteners 14 are used on the hollow rod 11 to connect the steel pipe, increasing the stiffness of the steel pipe connecting the outer frame and ensuring the safety of the scaffold structure.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
