Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a scaffolding member connection structure, a cup-lock scaffolding, and its application method. Background Technology

[0002] Scaffolding is a construction platform widely used in building engineering. Depending on the structure, scaffolding can be divided into several types, such as cup-lock, portal, and disc. Different building constructions require different types of scaffolding. The diverse scaffolding structures make it easier for construction workers to choose, ensuring the safety and convenience of building construction.

[0003] The existing invention patent with authorization announcement number CN102704670B discloses a lower cup buckle for cup buckle scaffolding, including a cup buckle body, a sleeve on the cup buckle body, and a recessed structure on the upright. Both the cup buckle body and the sleeve are fitted onto the upright. The inner wall of the sleeve is provided with a protrusion that extends into the recessed structure and is tightly fitted with the recessed structure.

[0004] As described in the above technical solution, a cup-lock scaffolding structure is provided, which mainly relies on the insert plates on the horizontal bars to cooperate with the cup lock and then lock it in place. The main problem with this type of scaffolding is that the insert plates may deform due to collisions or other factors during the disassembly and transportation of the scaffolding. This can cause the insert plates to fail to connect with the cup lock, affecting subsequent use; or after connection, there may be assembly gaps, resulting in instability after assembly and posing certain safety risks. This type of scaffolding has not been improved for a long time, so it is urgent to improve it. Summary of the Invention

[0005] In view of this, the present invention proposes a scaffolding member connection structure that is not easily deformed and can ensure good connection effect, a cup-lock scaffolding and its application method, to solve the problem that the existing scaffolding using plug-in connection is prone to component deformation and poses safety hazards.

[0006] The technical solution of this invention is implemented as follows:

[0007] On one hand, the present invention provides a scaffolding member connection structure, comprising:

[0008] Longitudinal bar;

[0009] The lower fastener is fixedly mounted on the longitudinal bar, and a first slot is provided on the lower fastener;

[0010] The upper fastener is slidably mounted on the longitudinal bar and is equipped with a pressure ring.

[0011] The horizontal bar is positioned opposite the vertical bar at its end, and there are multiple horizontal bars.

[0012] An insert plate is set at the end of the crossbar. One end of the insert plate is inserted into the first slot, and the other end is provided with a second slot. The pressure ring is inserted into the second slot.

[0013] The locking element is used to axially fix the upper fastener relative to the longitudinal bar.

[0014] Based on the above technical solutions, preferably, it also includes a spring, and both the upper fastener and the locking element are ring-shaped structures, with the locking element slidably connected to the longitudinal rod;

[0015] The spring is sleeved on the longitudinal rod, and the spring is located between the upper fastener and the locking element;

[0016] The longitudinal rod has a pin hole.

[0017] Based on the above technical solutions, preferably, the insert plate has an arc-shaped plate structure, the arc of the insert plate is less than a quarter circle, the insert plate has a stepped structure, and the small diameter section of the insert plate is inserted into the first slot.

[0018] A rocker arm is rotatably connected to the upper fastener. The rocker arm has a narrow section and a wide section. The narrow section of the rocker arm is connected to the upper fastener via a pivot, and the wide section is located between the large diameter section of the insert plate and the lower fastener, corresponding to the gap between two adjacent insert plates.

[0019] Based on the above technical solutions, preferably, a pressure block is provided at the end of the locking member facing the upper fastener, and the pressure block abuts against the narrow part.

[0020] Based on the above technical solutions, preferably, the end of the locking member facing the upper fastener has a flared structure.

[0021] Based on the above technical solutions, preferably, the upper fastener is provided with a latch at the end facing the locking member, and the pressure block is provided with a locking block on the side.

[0022] The latch and the lever are misaligned.

[0023] On the other hand, the present invention provides a cup-lock scaffold, including the above-mentioned scaffold member connection structure.

[0024] Furthermore, the present invention provides a cup-lock scaffolding, including the aforementioned scaffolding member connection structure, and further comprising:

[0025] The hanging rod is mounted on the swing arm;

[0026] The carrier plate is erected on the crossbar;

[0027] The pressure plate is connected to the carrier plate at one end and abuts against the hanging rod at the other end.

[0028] Based on the above technical solutions, the preferred option also includes hanging ropes, and the scaffolding pole connection structure is a multi-layered structure with a carrier plate on each layer of the scaffolding pole connection structure.

[0029] One end of the rope is connected to the hanging pole of the upper scaffold member connection structure, and the other end is connected to the carrier plate on the lower scaffold member connection structure.

[0030] Furthermore, the present invention provides a method for applying the above-mentioned cup-lock scaffolding, comprising the following steps:

[0031] S1. Insert the insert plate into the first slot to initially position the crossbar and the longitudinal bar;

[0032] S2. Slide the upper fastener so that the pressure ring is inserted into the second slot;

[0033] S3. Swing the lever to fill the gap between two adjacent insert plates;

[0034] S4. Rotate the locking element to adjust its position, then press the locking element so that the pressure block abuts against the narrow part of the rocker arm;

[0035] S5. Insert the locking pin into the pin hole to axially position the locking part, then place the carrier plate on the crossbar and install the pressure plate and / or hanging rope.

[0036] S6. When disassembling, remove the pressure plate and / or hanging rope, pull out the locking pin, move the locking part, and disengage the pressure block from the narrow part of the swing arm.

[0037] S7. Rotate the locking element to misalign the pressure block with the rocker arm;

[0038] S8. Press the locking element. The flared end of the locking element guides the rocker arm, causing the rocker arm to rotate and tilt, disengaging from the gap between two adjacent insert plates.

[0039] S9. Rotate the locking element to engage the latch with the locking block, then pull it up to disengage the pressure ring from the second slot.

[0040] S10. Disconnect the insert plate at the end of the crossbar from the first slot.

[0041] The scaffolding member connection structure, cup-lock scaffolding, and application method of the present invention have the following advantages over the prior art:

[0042] (1) By providing a second slot on the insert plate, it is convenient to insert and fix it with the pressure ring of the upper fastener. At the same time, when the crossbar is disassembled and stacked, the insert plate at one end of the crossbar can be inserted into the second slot on the insert plate at the end of the other crossbar. This can achieve the shaping of the insert plate and avoid the problem of impact damage to the insert plate. This can effectively ensure good insertion and removal shape and avoid deformation during disassembly and transportation, which may lead to safety hazards in subsequent applications. At the same time, the pressure ring of the upper fastener can be inserted into the first slot of the lower fastener to achieve relative fixation and avoid deformation of the upper and lower fasteners.

[0043] (2) The insert plate is set as an arc plate structure with an arc of less than a quarter circle. This means that during assembly, adjacent insert plates do not need to be close together, which facilitates the insertion and mating with the first slot. At the same time, the insert plate is divided into two parts: a small diameter section and a large diameter section, which makes it easy to open the second slot and ensures the structural strength.

[0044] (3) By setting a swing rod on the upper fastener, the upper fastener and the insert plate can be positioned relative to each other, thus ensuring the stability of the structure. At the same time, the swing rod is set with a narrow part and a wide part. The narrow part can effectively limit the two adjacent insert plates, while the wide part can stably support the end face of the step of the insert plate, thus ensuring the stability of the structure. This structure also makes the swing rod seal the gap between adjacent insert plates, which can prevent foreign objects from entering and prevent interference, thus ensuring the convenience of disassembly.

[0045] (4) By setting a pressure block on the locking part, the end of the swing rod can be pressed by the pressure block. When the locking pin is installed in the pin hole, the lower fastener, the insert plate, the upper fastener and the locking part are relatively axially limited on the longitudinal rod, which can ensure the structural stability and have good support performance.

[0046] (5) By setting the locking part with a flared structure, after the pressure plate and the swing rod are misaligned, multiple swing rods can be rotated at the same time by pressing the locking part, releasing the engagement with the insert plate, and then the upper fastener and the insert plate can be separated, which improves the convenience of operation.

[0047] (6) By setting a locking block on the locking part and a locking buckle on the upper buckle, the locking part can be rotated to make the locking block and the locking buckle cooperate, so as to avoid the locking part and the upper buckle being separated due to the spring force during disassembly, and to facilitate the simultaneous lifting of the locking part and the upper buckle, which further improves the convenience of operation.

Detailed Implementation

[0062] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0063] like Figures 1-11 As shown, the scaffolding member connection structure of the present invention includes a longitudinal member 1, a lower fastener 2, an upper fastener 3, a horizontal member 4, a insert plate 5, a locking member 6, and a spring 7;

[0064] The cup-lock scaffolding of the present invention includes the above-mentioned scaffolding connection structure, and also includes a hanging rod 8, a carrier plate 9, a pressure plate 10 and a hanging rope 11.

[0065] like Figures 1-10 As shown, there is a vertical rod 1; a lower fastener 2, which is fixedly mounted on the vertical rod 1 and has a first slot 100; an upper fastener 3, which is slidably mounted on the vertical rod 1 and has a pressure ring 31; a horizontal rod 4, which is positioned opposite to the vertical rod 1 at its end, and multiple horizontal rods 4 are provided; an insert plate 5, which is positioned at the end of the horizontal rod 4, with one end of the insert plate 5 inserted into the first slot 100 and the other end having a second slot 200, and the pressure ring 31 inserted into the second slot 200; and a locking member 6, which is used to axially fix the upper fastener 3 relative to the vertical rod 1.

[0066] As described above, the longitudinal rod 1 is used to connect to the base to provide support;

[0067] The first slot 100 on the lower fastener 2 is used to insert one end of the insert plate 5. Then, the upper fastener 3 is slid to insert the pressure ring 31 of the upper fastener 3 into the second slot 200 of the insert plate 5, so as to position the insert plate 5 and realize the connection between the horizontal bar 4 and the vertical bar.

[0068] In order to ensure the stability of the connection structure, a locking component 6 is set. After the upper fastener 3 is axially positioned by the locking component 6, the longitudinal bar 1, the lower fastener 2, the upper fastener 3, the horizontal bar 4 and the insert plate 5 are relatively positioned to ensure a stable support effect.

[0069] With this structure, when the crossbars 4 are disassembled and stacked, the insert plate 5 at the end of one crossbar 4 can be inserted into the second slot 200 on the insert plate 5 at the end of another crossbar 4. This can fix the shape of the insert plate 5 and avoid the problem of impact damage to the insert plate 5. This can effectively ensure that the insertion and removal shape is good, so as to avoid deformation during disassembly and transportation, which may lead to safety hazards in subsequent applications.

[0070] Meanwhile, after the insert plate 5 is removed, the pressure ring 31 of the upper fastener 3 can be inserted into the first slot 100 of the lower fastener 2 to achieve relative fixation, so as to prevent the upper fastener 3 and the lower fastener 2 from deforming due to external impacts and other factors.

[0071] like Figures 2-5 As shown, both the upper fastener 3 and the locking member 6 are ring-shaped structures, and the locking member 6 is slidably connected to the longitudinal rod 1; the spring 7 is sleeved on the longitudinal rod 1, and the spring 7 is located between the upper fastener 3 and the locking member 6; a pin hole 101 is provided on the longitudinal rod 1.

[0072] As described above, both the upper fastener 3 and the locking element 6 are designed as ring structures, which makes it easy to fit them onto the vertical rod 1 and slide them on the vertical rod 1, thereby achieving the locking and fixing of the insert plate 5.

[0073] Furthermore, a spring 7 is provided between the upper fastener 3 and the locking member 6. After the upper fastener 3 is inserted and fixed to the insert plate 5, the locking member 6 is pressed to compress the spring 7, and then the locking pin is inserted into the pin hole 101, so that the upper fastener 3 can cooperate with the lower fastener 2 to fix the insert plate 5 and the crossbar 4.

[0074] like Figure 2 and Figure 11 As shown, the insert plate 5 has an arc-shaped plate structure with an arc of less than a quarter circle. The insert plate 5 has a stepped structure, and the small diameter section of the insert plate 5 is inserted into the first slot 100. A swing rod 32 is rotatably connected to the upper fastener 3. The swing rod 32 has a narrow part 321 and a wide part 322. The narrow part 321 is connected to the upper fastener 3 through a pivot, and the wide part 322 is located between the large diameter section of the insert plate 5 and the lower fastener 2, corresponding to the gap between two adjacent insert plates 5.

[0075] As described above, the insert plate 5 is set as an arc-shaped plate structure and has a stepped structure, which makes it convenient for the large diameter section of the insert plate 5 to fit into the longitudinal rod 1 to ensure a good supporting effect, and also makes it convenient for the small diameter section to be inserted into the first slot 100.

[0076] Among them, the curvature of the insert plate 5 is less than a quarter circle, so that during assembly, adjacent insert plates 5 do not need to be in close contact, which facilitates the insertion and engagement with the first slot 100, thereby avoiding frictional interference between adjacent insert plates 5.

[0077] Furthermore, the upper fastener 3 is provided with a swing rod 32, so that after the upper fastener 3 is inserted into the second slot 200, the swing rod 32 can be rotated to close the gap between two adjacent insert plates 5.

[0078] The swing arm 32 is configured with a narrow part 321 and a wide part 322. The narrow part 321 can effectively limit the movement of two adjacent insert plates 5, while the wide part 322 can stably support the end face of the step of the insert plate 5, thereby ensuring the stability of the structure.

[0079] This structure also seals the gap between the swing arm 32 and the adjacent insert plate 5, preventing foreign objects from entering and thus preventing interference, thereby ensuring ease of disassembly.

[0080] This ensures that the connection mechanism of this member is not affected by foreign objects such as sand and gravel during construction, and has good application reliability;

[0081] like Figure 2 , Figure 10 and Figure 11 As shown, a pressure block 61 is provided at one end of the locking member 6 facing the upper fastener 3, and the pressure block 61 abuts against the narrow part 321;

[0082] As described above, by setting a pressure block 61 on the locking member 6, the end of the swing rod 32 can be pressed by the pressure block 61 to limit the swing rod 32. When the locking pin is installed into the pin hole 101, the lower fastener 2, the insert plate 5, the upper fastener 3 and the locking member 6 are relatively axially limited on the longitudinal rod 1, which can ensure the stability of the structure, form a rigid connection as a whole, and be unaffected by the elastic force of the spring 7, thus having good support performance.

[0083] like Figure 2 , Figure 5 ,like Figure 8 and Figure 11 As shown, the end of the locking member 6 facing the upper fastener 3 has a flared structure;

[0084] As described above, when the swing rod 32 is positioned relative to the upper fastener 3 and the insert plate 5, the wide part 322 of the swing rod 32 will abut against the stepped surface of the insert plate 5. It cannot be directly separated during disassembly. It can only be separated by rotating the swing rod 32 and tilting it. However, since there are multiple swing rods 32, it is time-consuming and laborious to adjust the position of the swing rod 32 individually. Therefore, it can be adjusted synchronously by locking part 6.

[0085] During operation, release the locking pin. At this time, the locking part 6 can slide on the vertical rod 1. First, move the locking part 6 away from the upper buckle 3 so that the pressure block 61 separates from the end of the swing rod 32. Then rotate the locking part 6 to offset the pressure block 61 from the swing rod 32. Then press the locking part 6. When the flared structure of the locking part 6 contacts the end of the swing rod 32, all the swing rods 32 will rotate under the guidance of the flared structure of the locking part to disengage from the insert plate 5. Then lift the locking part 6 and the upper buckle 3 together to disengage from the insert plate 5. This effectively improves the convenience of disassembly and assembly.

[0086] like Figure 2 , Figure 5 and Figure 11 As shown, a latch 33 is provided at one end of the upper fastener 3 facing the locking member 6, and a locking block 62 is provided on the side of the pressure block 61; the latch 33 and the swing rod 32 are offset.

[0087] As described above, by setting a locking block 62 on the locking member 6 and a locking buckle 33 on the upper fastener 3, during disassembly, the locking member 6 is first pressed against the upper fastener 3, and then the locking member 6 can be rotated to engage the locking block 62 and the locking buckle 33. This prevents the locking member 6 from separating from the upper fastener 3 due to the elastic force of the spring 7 during disassembly. Under the action of the spring 7, the locking block 62 and the locking buckle 33 are stably engaged, and the upper fastener 3 and the locking member 6 will not separate. The swing rod 32 always remains tilted and will not fall back to jam the insert plate 5. At this time, the upper fastener 3 and the insert plate 5 can be lifted and separated simply by holding the swing rod 32 or the locking member 6, which further improves the convenience of operation. Afterwards, the locking member 6 is rotated again to separate the locking block 62 and the locking buckle 33, and the upper fastener 3 and the locking member 6 will separate under the action of the spring 7.

[0088] In some embodiments, in the scaffold member connection structure of the present invention, there are two pin holes 101, one of which is close to the lower fastener 2 and the other is relatively far away. The pin hole 101 far away from the lower fastener 2 is used to install the locking pin positioning plate 5, and the pin hole 101 close to the lower fastener 2 is used to install the locking pin to fix the upper fastener 3 and the lower fastener 2 relatively.

[0089] Specifically, after the crossbar 4 and the insert plate 5 are disassembled, the pressure ring 31 of the upper fastener 3 is inserted into the first slot 100 of the lower fastener 2 to achieve relative abutment and fixation between the two to avoid deformation due to collision. At this time, the locking part 6 and the spring 7 are moved to the lower fastener 2. After the spring 7 abuts against the upper fastener 3, the locking part 6 is pressed to compress the spring 7. Then, the locking pin is inserted into the pin hole 101 near the lower fastener 2 for positioning to ensure structural stability.

[0090] like Figure 11 and Figure 12As shown, the hanging rod 8 is set on the swing rod 32; the carrier plate 9 is built on the crossbar 4; the pressure plate 10 is connected to the carrier plate 9 at one end and abuts against the hanging rod 8 at the other end.

[0091] As described above, the hanging rod 8 is used to limit the swing rod 32 to prevent the swing rod 32 from failing to stably cooperate with the pressure block 61 due to wear, thereby preventing the swing rod 32 from overturning during the application of the scaffold.

[0092] Specifically, the crossbar 4 is used to lay the carrier plate 9, which serves as a construction platform;

[0093] When laying the carrier plate 9, a pressure plate 10 is set on the carrier plate 9 to press down the hanging rod 8 on the swing rod 32, which can further ensure the stability of the swing rod 32 and prevent the swing rod 32 from shifting.

[0094] In some embodiments, to avoid any gaps in the fit, the pressure plate 10 may be configured as a spring rod to ensure that it can stably hold the swing arm 32.

[0095] In some embodiments, the scaffolding member connection structure is arranged in a multi-layered structure, and each layer of the scaffolding member connection structure is provided with a carrier plate 9; one end of the hanging rope 11 is connected to the hanging rod 8 of the upper layer of the scaffolding member connection structure, and the other end is connected to the carrier plate 9 of the lower layer of the scaffolding member connection structure.

[0096] As described above, the present invention provides a structure that enhances the positional stability of the swing arm 32;

[0097] The scaffolding members are often built in multiple layers. In this case, the carrier plate 9 on the lower layer of scaffolding members can be connected to the hanging rod 8 on the upper layer of scaffolding members by the hanging rope 11. The weight of the carrier plate 9 on the lower layer of scaffolding members pulls the hanging rod 8, thereby ensuring the positional stability of the swing rod 32 and achieving mutual reinforcement of the upper and lower layers of scaffolding member structures.

[0098] The application method of the cup-lock scaffolding of the present invention includes the following steps:

[0099] S1. Insert the insert plate 5 into the first slot 100 to initially position the crossbar 4 and the vertical bar 1.

[0100] S2. Slide the upper fastener 3 so that the pressure ring 31 is inserted into the second slot 200;

[0101] S3. Swing the swing rod 32 to fill the gap between two adjacent insert plates 5;

[0102] S4. Rotate the locking member 6 to adjust its position, then press the locking member 6 so that the pressure block 61 abuts against the narrow part 321 of the swing rod 32.

[0103] S5. Insert a locking pin into the pin hole 101 to axially position the locking part 6. Then, place the carrier plate 9 on the crossbar 4 and install the pressure plate 10 and / or hanging rope 11.

[0104] S6. When disassembling, remove the pressure plate 10 and / or the hanging rope 11, remove the locking pin, move the locking part 6, and disengage the pressure block 61 from the narrow part 321 of the swing arm 32.

[0105] S7. Rotate the locking component 6 to misalign the pressure block 61 with the swing rod 32;

[0106] S8. Press the locking part 6. The flared end of the locking part 6 guides the swing rod 32. The swing rod 32 rotates and tilts, disengaging from the gap between the two adjacent insert plates 5.

[0107] S9. Rotate the locking member 6 to make the latch 33 engage with the locking block 62, and then pull it up to make the pressure ring 31 disengage from the second slot 200.

[0108] S10. Disconnect the insert plate 5 at the end of the crossbar 4 from the first slot 100.

[0109] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
