Description

TECHNICAL FIELD

[0001] The present application belongs to the field of building scaffold, in particular to a disc buckle structure of disc buckle scaffold, a vertical rod and a scaffold support structure. BACKGROUND

[0002] The disc buckle scaffold, also known as round disc scaffold, chrysanthemum disc scaffold, disc insertion scaffold, wheel disc scaffold, and Layher scaffold, is similar to general scaffolds and includes vertical rods, horizontal rods, diagonal rods, and adjustable bases. The difference is that the vertical rods are steel pipes of a certain length with a disc welded at intervals. The horizontal rods and diagonal rods are connected to the vertical rods through a disc structure. The disc has eight holes, four of which are used to connect the horizontal rods and the other four are used to connect the diagonal rods. The horizontal rods and diagonal rods have similar connecting heads for connection with the disc. The connecting head is U-shaped with a hole in each arm. The horizontal rods are fixed to the connecting head, and the diagonal rods are connected to the connecting head through a hinge. When connected, the disc is in the opening of the U-shaped connecting head. The connecting head and the disc are fixed by a pin that passes through the hole and the hole in the disc. To make installation easier, the pin has a pin at one end. The two holes in the connecting head are different sizes, so the pin can only pass through one hole, allowing the pin to move with the connecting head. This disc scaffold is easy to install and disassemble. Only a hammer-like tool is needed to install and disassemble the scaffold. The pin is hammered down to make it tight or hammered up to make it loose.

[0003] This form of pin may cause the connecting head and the disc to completely separate if the pin is loose or the hammering step is missed during installation and construction. Accidental contact or strong vibration may cause the connecting head and the disc to completely separate, posing a certain safety hazard. However, due to the error in the shape of the parts, the pin may be tight or just fall on the connecting head by gravity, which cannot be reliably judged by visual inspection. Workers need to feel the tightness one by one during maintenance and repair, which is a large workload and prone to omissions. SUMMARY

[0004] The present application aims to solve the problem of the need for separate hammering of each pin during installation and disassembly in the prior art, and the large workload of installation, disassembly, maintenance and repair. The present application provides a disc buckle structure of disc buckle scaffold, a vertical rod and a scaffold support structure.

[0005] The above technical purpose of the present application is achieved by the following technical scheme:

[0006] The disc buckle structure of a disc buckle type scaffold comprises a buckle disc, a limiting piece fixedly connected to the buckle disc, a constraint disc slidingly connected to the limiting piece, a plurality of inserting pieces and a locking assembly arranged on the constraint disc, wherein the buckle disc is provided with a horizontal rod hole and an inclined rod hole, the constraint disc is arranged above the buckle disc, the inserting pieces are arranged in one-to-one correspondence with the horizontal rod holes and the inclined rod holes respectively, the limiting piece is provided with a first limiting part and a second limiting part, when the locking assembly is locked with the first limiting part of the limiting piece, the inserting pieces are arranged above the buckle disc and the interval between the inserting pieces and the buckle disc is not less than the thickness w of an arm of a connecting head, and when the locking assembly is locked with the second limiting part of the limiting piece, the inserting pieces are inserted into the corresponding horizontal rod holes and inclined rod holes.

[0007] According to the technical scheme, the eight inserting pieces corresponding to the eight hole positions are simultaneously inserted into the buckle disc by the constraint disc, and the locking assembly is used to lock the height position of the constraint disc, so that the inserting state position of the inserting pieces is limited, even if the inserting pieces are not tightly inserted with the connecting head and the buckle disc, the connecting head and the buckle disc can also be prevented from being completely separated due to accidental touch or large vibration, and thus it is not necessary to individually hammer each connecting piece during installation and disassembly, which helps to reduce the workload of installation and disassembly and the tools required during operation; in addition, since the constraint disc needs to surround the vertical rod, it is difficult for accidental touch acting on the individual inserting pins or the constraint disc to provide a vertical upward force to the constraint disc, and the accidental touch with horizontal force component can instead increase the friction force between the constraint disc and the vertical rod, so that the locking assembly bearing the eight inserting pieces bears less external force than the single inserting pin in the prior art, and the reliability is higher. In addition, the inserting pieces do not need to be tightly inserted, and the height position of each inserting piece on the constraint disc can reflect the height position of each inserting piece, so that the number of nodes to be judged during maintenance is much less than that of the conventional scaffold, and the workload of maintenance can be greatly simplified.

[0012] Preferably, a plurality of groups of the sliding block and the sliding groove are correspondingly arranged, each sliding groove is arranged in a different direction and is obliquely arranged, and the end of the sliding groove approaching the limiting part is higher than the end of the sliding groove moving away from the limiting part.

DETAILED DESCRIPTION

[0041] The present application is further described in detail below with reference to the accompanying drawings. Identical parts are denoted by identical reference signs.

[0042] A scaffold support structure, such asFigure 1 As shown, it comprises upright poles 200, horizontal poles 300, inclined poles 400 and adjustable bases 500, as shown in Figure 2 As shown, the upright pole 200 comprises a pole body 210 and disc buckle structures 100, and several disc buckle structures 100 are evenly arranged along the length direction of the pole body 210. As shown in Figure 3 As shown, the horizontal pole 300 comprises a pole body 310 and a connecting head 320 fixedly connected at both ends of the pole body 310, as shown in Figure 4 As shown, the inclined pole 400 comprises a pole body 410 and a connecting head 420 hingedly connected at both ends of the pole body 410, and the connecting head 320 and the connecting head 420 are similar in structure, both of which are U-shaped, and both arms of the U-shaped are provided with insertion holes, and the edges of the connecting head 320 and the connecting head 420 are provided with chamfers. The adjustable base 500 is threadedly connected with an adjusting nut 510, the upright pole 200 is inserted on the threaded rod of the adjustable base 500 and falls on the adjusting nut 510, and the height of the upright pole 200 can be adjusted by rotating the adjusting nut 510. The horizontal pole 300 is horizontally arranged between two upright poles 200, the connecting head 320 at both ends of the horizontal pole 300 is respectively connected to the disc buckle structures 100 of the same height on the two upright poles 200, and the connecting head 420 at both ends of the inclined pole 400 is respectively connected to the disc buckle structures 100 of different heights on two adjacent upright poles 200.

[0043] The disc buckle structure 100 of the disc buckle type scaffold of the upright pole 200, as shown in Figure 5 and Figure 6 As shown, it comprises a buckle disc 110, a limiting piece 120, a constraint disc 130, an insertion piece 140 and a locking assembly. The buckle disc 110 is a circular ring and is welded on the pole body 210, four horizontal pole holes 111 and four inclined pole holes 112 are formed on the buckle disc 110, the horizontal pole holes 111 and the inclined pole holes 112 are arranged at intervals and are uniformly distributed on the buckle disc 110.

[0044] The limiting member 120 is integrally fixed to the buckle disc 110. The limiting member 120 can adopt various shapes as long as it can constrain the sliding and positioning of the restraint disc 130. In the embodiment, the limiting member 120 is a circular tube, and the limiting member 120 is coaxially arranged with the buckle disc 110 and has an inner diameter equal to that of the buckle disc 110. A guide groove 123 for guiding the sliding of the restraint disc 130 is formed in the outer circumferential surface of the limiting member 120, and the length direction of the guide groove 123 is parallel to the axis of the buckle disc 110. The restraint disc 130 is a whole circular ring, and a guide strip 1301 matched with the guide groove 123 is arranged on the inner wall of the restraint disc 130. The restraint disc 130 comprises a disc body 131 and a cover body 132. Eight slide holes 133 matched with the inserting members 140 are formed in the disc body 131, and each slide hole 133 is arranged directly above a horizontal rod hole 111 or an inclined rod hole 112. An inserting member 140 is arranged in each slide hole 133, and the inserting member 140 can slide along the axis of the buckle disc 110. A limiting flange 141 is arranged at the top end of the inserting member 140 to prevent the inserting member 140 from sliding upwards from below the disc body 131. The cover body 132 can prevent the inserting member 140 from sliding downwards from above the disc body 131. The bottom end of the inserting member 140 extends out of the lower surface of the disc body 131 and is provided with a chamfer. As shown in Figure 10 , the locking assembly comprises a slide groove 134 formed between the disc body 131 and the cover body 132 and a slide block 135 matched with the slide groove 134. The slide block 135 slides in the slide groove 134 to approach or move away from the limiting member 120. The side of the slide groove 134 close to the limiting member 120 penetrates the disc body 131, and a part of the slide block 135 can slide out of the disc body 131 from the slide groove 134. Figure 6 As shown in Figure 7 , when the locking assembly is locked in the first limiting portion, the inserting member 140 is always located above the buckle disc 110, and the interval between the inserting member 140 and the buckle disc 110 is not less than the thickness w of the arm of the connecting head 320. At this time, there is enough distance between the inserting member 140 and the buckle disc 110 to ensure that the inserting member 140 does not interfere with the movement of the connecting head to the buckle disc 110. Figure 8 As shown in Figure 9As shown, when the locking assembly is locked at the third limiting part, the position of the connecting piece is between the fully locked position and the fully unlocked position. If the connecting piece 140 slides to the highest position, the interval between the connecting piece 140 and the buckle disc 110 is not less than the thickness w of the arms of the connecting head one 320. If the connecting piece 140 is located at the lowest position, the connecting piece 140 is above the buckle disc 110 and the interval between the two is less than the thickness w of the arms of the connecting head one 320. The third limiting part is used to realize the pre-fixing function. When the connecting head of the cross rod 300 or the inclined rod 400 is inserted into the buckle disc 110, the connecting head can be translated by being abutted on the chamfer of the connecting piece 140, so that the connecting piece 140 can slide upward. When the connecting piece 140 contacts the top of the connecting head and encounters the insertion hole on the connecting head, the connecting piece 140 can fall into the insertion hole under the action of gravity. Since there is no chamfer in the insertion hole, the connecting piece 140 can be stably inserted into the connecting head, so that the pre-fixing of the connecting head and the buckle disc 110 can be realized. Only a simple insertion operation is needed to install the cross rod 300 and the inclined rod 400 to the accurate position. In order to facilitate the unlocking operation, the cover body 132 is provided with a through hole, and the sliding block 135 is fixedly provided with an operating block 136 extending out of the through hole. In order to increase the range that can be contacted by the hand, the operating block 136 is in the shape of a long strip. In the embodiment, the operating block 136 is provided with an arc-shaped long strip. The upper surface of the operating block 136 is provided with a force plate 137, so as to facilitate the force exerted by the fingers of the human hand.

[0045] In the embodiment, as shown in Figure 7 、 Figure 8 and Figure 9 , the top surface of the limiting piece 120 serves as the first limiting part. When the locking assembly is locked with the first limiting part, the sliding block 135 falls on the top surface of the limiting piece 120, preventing the restraint ring from sliding downward. The second limiting part is a limiting groove two 121 opened on the limiting piece 120. When the locking assembly is locked with the second limiting part, the end of the sliding block 135 close to the limiting piece 120 extends into the limiting groove two 121, preventing the restraint ring from moving up and down. The third limiting part is a limiting groove three 122 opened on the limiting piece 120. When the locking assembly is locked with the second limiting part, the end of the sliding block 135 close to the limiting piece 120 extends into the limiting groove three 122, preventing the restraint ring from moving up and down. In order to avoid that simple vibration or accidental touch unlocks the locking assembly, multiple sets of the sliding block 135 and the sliding groove 134 are correspondingly arranged. Each sliding groove 134 is arranged in a different direction and is obliquely arranged. The end of the sliding groove 134 close to the limiting piece 120 is higher than the end away from the limiting piece 120, so as to rely on the gravity to keep the locking position of the limiting piece 120 at the low position stable. In order to further improve the locking stability, as shown in Figure 11 , an elastic piece 138 can be arranged in the sliding groove 134. The elastic piece 138 applies an elastic force to the sliding block 135 in the corresponding sliding groove 134, which is directed toward the limiting piece 120. Figure 12As shown, magnetic attraction structures can also be provided on the sliding groove 134 and the sliding block 135 respectively or simultaneously, for example, a magnetic piece 139 is provided on one of the sliding groove 134 and the sliding block 135, and when the locking assembly is locked with the limiting piece 120, the magnetic attraction structures are in an attraction state. One of the inclined sliding groove 134 structure, the elastic piece 138 and the magnetic attraction structure can be used in the locking assembly, or a combination of several schemes can be used simultaneously.

[0046] When the scaffold is built, first place the adjustable base 500 according to the plan, adjust the height of the adjusting nut 510, insert each vertical rod 200, and the constraint disc 130 is pre-set in the second limiting part, then install the cross rod 300, directly top the two ends of the cross rod 300 into the corresponding position of the buckle disc 110, and the corresponding insertion piece 140 rises under the guidance of the chamfer and then falls into the insertion hole, completing the fixing of the cross rod 300, and then pre-fix the diagonal rod 400, the pre-fixing process of the diagonal rod 400 is similar to that of the cross rod 300, which will not be described here. When all the connecting heads that need to be connected on one buckle disc 110 are pre-fixed, the user simultaneously pushes the operation blocks 136 with fingers to move away from the vertical rod 200, so that the sliding block 135 slides out of the limiting groove three 122, and then moves the constraint disc 130 downward, so that each insertion piece 140 is inserted into the corresponding insertion hole, until the sliding block 135 passes through the limiting groove two 121 and slides into it, and the constraint disc 130 and the insertion piece 140 are locked with the limiting piece 120, completely completing the installation of this node, and then connecting the subsequent cross rods 300 and diagonal rods 400.

[0047] When disassembling, the user simultaneously pushes the operation blocks 136 with fingers to move away from the vertical rod 200, so that the sliding block 135 slides out of the limiting groove three 122, and then pulls the constraint disc 130 upward, so that each insertion piece 140 slides out of the corresponding insertion hole, until the sliding block 135 is above the limiting piece 120, and the operation blocks 136 are released, so that each insertion piece 140 is completely separated from each connecting head, at this time, each cross rod 300 and diagonal rod 400 of this node can be easily removed, and after the investigation, the constraint disc 130 is preferably moved to the second limiting part to facilitate the next installation.

[0048] It should be noted that the disc body 131 and the cover body 132 of the constraint disc 130 can adopt a whole ring structure, but in this way, when the disc buckle structure 100 is installed on the vertical rod 200, the constraint disc 130 needs to be pre-sleeved on the vertical rod 200 before welding each buckle disc 110, which may cause some inconvenience during welding. Therefore, as shown in the drawings, Figure 13As shown, the constraint disc 130 can also be provided in a two half-ring structure, and after the buckle disc 110 is welded, the constraint disc 130 is installed, the two half-ring structure is specifically that the disc body 131 is a ring structure formed by two half-ring discs 1311, the cover body 132 is a ring cover formed by two half-ring covers 1321, and each half-ring cover 1321 is connected with the two half-ring discs 1311 through bolts. In this way, the cover body 132 can be connected with the half-ring disc 1311 and the half-ring cover 1321 in a staggered manner, and the cover body 132 can be used to constrain the plug-in part 140 and the sliding block 135 or to connect the two half-ring discs 1311.

[0049] In addition, the buckle structure 100 of the scaffold can fix the plug-in part 140 on the constraint disc 130, and the related setting of the third limiting part is cancelled, so that the scaffold does not have a pre-fixing function, but the setting cost can be reduced.

[0050] The specific embodiment is only an explanation of the present application, and is not a limitation of the present application.
