Description

Technical Field

[0001] The invention relates to the technical field of scaffolds, in particular to a disc-type scaffold. Background Art

[0002] The connection node technology of the disc-type scaffolding originated in Germany and is a mainstream product in Europe and America. The disc-type scaffolding is becoming more and more popular due to its high bearing capacity, fewer components and simple combination. The connection of its columns is achieved by socketing and fixing with bolts, and the connection between the columns and the crossbars is achieved by welding the fixing plates on the columns and bolts.

[0003] For example, Chinese patent publication number CN110145110A discloses a disc-type scaffolding, including a vertical pole and a connecting rod welded to one end of the vertical pole, wherein a No. 1 extrusion protrusion, an adjustment groove and a No. 1 fastening hole are provided on the side of the vertical pole away from the connecting rod, and the No. 1 extrusion protrusion is located on the inner side wall of the vertical pole, and a No. 2 extrusion protrusion, an adjustment hole and a No. 2 fastening hole are respectively provided on the side wall of the connecting rod corresponding to the No. 1 extrusion protrusion, the adjustment groove and the No. 1 fastening hole.

[0004] For example, Chinese patent publication number CN110409778A discloses a disc-type scaffold with two fixed discs, including vertical poles, horizontal poles, diagonal poles and trapezoidal pins. Fixed discs and movable discs are arranged on the vertical poles, and trapezoidal slots a and trapezoidal slots b are respectively provided on the fixed discs and the movable discs. Trapezoidal slots c and trapezoidal slots are respectively provided on the horizontal poles and the diagonal poles. The horizontal poles and the diagonal poles are fixed between the fixed discs and the movable discs by the cooperation of the trapezoidal pins with the trapezoidal slots a, the trapezoidal slots b, the trapezoidal slots c and the trapezoidal slots.

[0005] The defect of the above-mentioned existing scaffolding is that the connection and fixation between the uprights and the uprights and between the uprights and the cross bars of the existing disc-type scaffolding are mostly installed and fixed by multiple bolts or pins. By using multiple bolts and pins, the installation process is relatively cumbersome and complicated, and the bolts exposed to the outside are prone to rust. There are certain safety hazards if they are installed and fixed only from the outside by bolts. It is not easy to install and fix from both the inside and the outside at the same time, which reduces the stability and firmness of the installation. Therefore, improvement is needed. Summary of the invention

[0006] The object of the present invention is to provide a disc-type scaffolding, which has the function of realizing double fixation from the inside and the outside for the connection between the vertical bar one and the vertical bar two, and the connection and fixation between the vertical bar one and the vertical bar two and the cross bar, which also realizes double fixed connection from the inside and the outside, and also reinforces the connection between the vertical bar one and the vertical bar two, as well as the connection between the vertical bar one and the cross bar and between the vertical bar two and the cross bar, thereby avoiding breakage at the connection, making the installation and fixation of the scaffolding more firm and stable, and simple and convenient to operate, without the need to use a large number of bolts for fixation, thereby solving the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a disc-type scaffolding, comprising a plurality of vertical rods 1 and 2, wherein a cross bar is provided at the connection between the vertical rods 1 and 2, a reinforcing sleeve is provided at the contact point between the vertical rods 1 and 2, and grooves for placing the reinforcing sleeves are provided at the ends of the vertical rods 1 and 2.

[0008] The ends of the vertical rod one and the vertical rod two are provided with grooves, and a plug-in rod is fixedly connected in the groove at the end of the vertical rod one, and a plug-in sleeve is fixedly connected in the groove at the end of the vertical rod two, and the plug-in rod is plugged in the plug-in sleeve, and the ends of the vertical rod one and the vertical rod two are fixedly connected with a mounting plate, and a fixing component is provided on the cross bar, and the fixing component is used to press the mounting plate to fix the vertical rod one and the vertical rod two, and a locking component is provided inside the cross bar, and the locking component is used to be inserted into the plug-in rod and the plug-in sleeve.

[0009] Preferably, the reinforcement sleeve is made of steel with high structural strength.

[0010] Preferably, the mounting plate comprises a vertical plate and a horizontal plate, the vertical plate is in contact with and fixedly connected to the surface of the first vertical rod or the second vertical rod, and the horizontal rod is provided with an indented groove for accommodating the horizontal plate.

[0011] Preferably, the fixing assembly includes an external thread opened on the cross bar, an internal thread sleeve is threadedly connected to the external thread, and the cross plate is located in the internal thread sleeve.

[0012] Preferably, a lever is fixedly connected to the internal threaded sleeve for facilitating the rotation of the internal threaded sleeve.

[0013] Preferably, a placement groove is provided on the cross plate, a cavity is provided in the cross bar, through holes connecting the placement groove and the cavity are provided on the cross plate and the cross bar, an extrusion rod is slidably arranged in the through hole, an arc plate is fixedly connected to one end of the extrusion rod close to the internal threaded sleeve, and a first elastic member for pushing the arc plate to contact the internal threaded sleeve is sleeved on the extrusion rod.

[0014] Preferably, the locking assembly includes a hole opened at the end of the cross bar, and the hole and the cavity are interconnected, a clamping rod is slidably connected in the hole, a wedge block is fixedly connected to one end of the clamping rod, and the other end of the plug rod is inserted into the reinforcement sleeve, the plug rod and the plug sleeve in sequence, and a clamping groove matching the clamping rod is opened in the reinforcement sleeve, the plug rod and the plug sleeve.

[0015] Preferably, the bottom end of the extrusion rod is provided with an inclined surface matched with the upper inclined surface of the wedge block.

[0016] Preferably, a second elastic member is sleeved on the clamping rod

[0017] Preferably, the first elastic member is a first spring, the two ends of which are respectively connected to the inner wall of the placement groove and the arc plate, and the second elastic member is a second spring, the two ends of which are respectively connected to the inner wall of the cavity and the wedge block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By setting the reinforcing sleeve, the connection between the vertical bar 1 and the vertical bar is reinforced, and by setting the mounting plate, the connection between the vertical bar 1 and the horizontal bar and between the vertical bar 2 and the horizontal bar is reinforced, avoiding breakage at the connection and making the installation and fixation of the scaffolding more firm and stable.

[0020] Second, through the arrangement of the vertical plate, the horizontal plate, the sunken groove, the external thread and the internal thread sleeve, when the internal thread sleeve comes into contact with the vertical plate, the internal thread sleeve will press the horizontal plate into the sunken groove, thereby realizing the initial fixation of the vertical rod 1 and the vertical rod from the outside, and the connection and fixation between the vertical rod 1 and the vertical rod 2 and the horizontal rod from the outside.

[0021] 3. By setting the placement groove, the arc plate, the extrusion rod and the first spring, when the internal threaded sleeve is rotated to press the horizontal plate, the elastic force of the first spring will be overcome to push the arc plate to shrink into the placement groove, thereby pushing the extrusion rod to be inserted into the through hole of the cross bar, thereby realizing the connection and fixation of the cross bar from the inside. The cross bar can withstand greater lateral tension, so that when the cross bar is subjected to lateral tension, it will not be separated from the vertical bar, and the connection with the vertical bar will be more stable and firm.

[0022] Fourth, through the arrangement of the wedge block, the clamping rod, the second spring and the clamping groove, since the inclined surface on the wedge block is adapted to the inclined surface at the bottom end of the extrusion rod, when the extrusion rod is inserted into the cross bar, it will overcome the elastic force of the second spring and push the clamping rod to be inserted into the reinforcing sleeve, the plug-in sleeve and the plug-in rod in sequence, thereby realizing the re-fixation of the vertical rod one and the vertical rod two from the inside, and increasing the vertical bearing tension at the connection between the vertical rod one and the vertical rod two, making the connection between the vertical rod one and the vertical rod two more firm and stable.

[0023] 5. In summary, through the coordinated use of the above-mentioned related structures, the connection between the vertical rod one and the vertical rod two is double fixed, and the connection and fixation between the vertical rod one, the vertical rod two and the cross rod is also double fixed, and the fixation between the vertical rod one, the vertical rod two and the cross rod is carried out simultaneously, avoiding a single back and forth installation and fixation, and also reinforcing the connection between the vertical rod one and the vertical rod two, as well as the connection between the vertical rod one and the cross rod and the vertical rod two and the cross rod, avoiding breakage at the connection, and the operation is simple and convenient, without the need to use a large number of bolts for fixing, thereby improving operating efficiency.

DETAILED DESCRIPTION

[0032] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 7The present invention provides a technical solution: a disc-type scaffolding, comprising a plurality of vertical bars 1 and vertical bars 2, a cross bar 3 is arranged at the connection between the vertical bars 1 and the vertical bars 2, a reinforcing sleeve 4 is sleeved at the contact between the vertical bars 1 and the vertical bars 2, and grooves for placing the reinforcing sleeve 4 are opened at the ends of the vertical bars 1 and the vertical bars 2.

[0034] The ends of the vertical rod 1 and the vertical rod 2 are both provided with grooves, and the groove at the end of the vertical rod 1 is fixedly connected with a plug rod 5, and the groove at the end of the vertical rod 2 is fixedly connected with a plug sleeve 6, the plug rod 5 is plugged into the plug sleeve 6, and the ends of the vertical rod 1 and the vertical rod 2 are both fixedly connected with a mounting plate 7, and a fixing component is provided on the cross bar 3, and the fixing component is used to press the mounting plate 7 to fix the vertical rod 1 and the vertical rod 2, and a locking component is provided inside the cross bar 3, and the locking component is used to be inserted into the plug rod 5 and the plug sleeve 6.

[0035] Furthermore, the reinforcing sleeve 4 is made of steel with high structural strength, and the reinforcing sleeve 4 reinforces the connection between the vertical rod 1 and the vertical rod 2, thereby preventing the connection from breaking when subjected to an inclined tensile force.

[0036] Furthermore, the mounting plate 7 includes a vertical plate 71 and a horizontal plate 72. The vertical plate 71 is attached to and fixedly connected to the surface of the vertical bar 1 or the vertical bar 2. The horizontal bar 3 is provided with an inner groove for placing the horizontal plate 72. When the horizontal plate 72 is connected and fixed to the horizontal bar 3 through a fixing assembly, the mounting plate 7 plays a role of preliminary connection and fixation of the vertical bar 1 and the vertical bar 2, and at the same time plays a role of supporting and reinforcing the connection between the vertical bar 1 and the horizontal bar 3, as well as the vertical bar 2 and the horizontal bar 3, avoiding breakage at the connection, thereby making the installation and fixation of the scaffolding more firm and stable.

[0037] Furthermore, the fixing assembly includes an external thread formed on the cross bar 3 , an internal thread sleeve 8 is threadedly connected to the external thread, and the cross plate 72 is located inside the internal thread sleeve 8 .

[0038] When it is necessary to install and fix the vertical rod 1, the vertical rod 2 and the cross bar 3, first put on the reinforcing sleeve 4, then insert the connecting rod 5 into the connecting sleeve 6, the cross plate 72 is located in the sunken groove, and then rotate the internal threaded sleeve 8. When the internal threaded sleeve 8 is rotated to contact the vertical plate 71, the internal threaded sleeve 8 will press the cross plate 72 tightly into the sunken groove, thereby realizing the preliminary fixation of the vertical rod 1 and the vertical rod 2 from the outside, and the connection and fixation between the vertical rod 1 and the vertical rod 2 and the cross bar 3 from the outside, and the installation and fixation of the three are carried out simultaneously, and there is no need to use a large number of bolts, thereby improving the installation efficiency.

[0039] Furthermore, a lever 9 is fixedly connected to the internal threaded sleeve 8 for facilitating the rotation of the internal threaded sleeve 8. The arrangement of the lever 9 makes it easier and more convenient to rotate the internal threaded sleeve 8.

[0040] Furthermore, a placement groove is provided on the cross plate 72, a cavity is provided in the cross bar 3, through holes connecting the placement groove and the cavity are provided on the cross plate 72 and the cross bar 3, an extrusion rod 10 is slidably arranged in the through hole, an arc plate 11 is fixedly connected to one end of the extrusion rod 10 close to the internal threaded sleeve 8, and a first elastic member for pushing the arc plate 11 to contact the internal threaded sleeve 8 is sleeved on the extrusion rod 10.

[0041] When the internal threaded sleeve 8 is rotated to press the cross plate 72, the arc plate 11 can be pressed by hand first, so that the arc plate 11 is retracted into the placement groove, and then the internal threaded sleeve 8 is rotated. When the internal threaded sleeve 8 presses one end of the arc plate 11, the pressure on the arc plate 11 by hand can be released, and then the internal threaded sleeve 8 is continued to be rotated, which will overcome the elastic force of the first spring 14 to push the arc plate 11 to retract into the placement groove, thereby pushing the extrusion rod 10 to be inserted into the through hole of the cross bar 3, thereby realizing the connection and fixation between the mounting plate 7 and the cross bar 3 from the inside. The cross bar 3 can withstand a larger lateral pulling force, so that the cross bar 3 will not be separated from the vertical rod when subjected to lateral pulling force, and the connection with the vertical rod is more stable and firm.

[0042] Furthermore, the locking assembly includes a hole opened at the end of the cross bar 3, and the hole and the cavity are interconnected. A clamping rod 12 is slidably connected in the hole, and a wedge block 13 is fixedly connected to one end of the clamping rod 12. The other end of the clamping rod 12 is inserted into the reinforcement sleeve 4, the plug-in rod 5 and the plug-in sleeve 6 in turn, and a clamping groove adapted to the clamping rod 12 is opened in the reinforcement sleeve 4, the plug-in rod 5 and the plug-in sleeve 6.

[0043] Furthermore, the bottom end of the extrusion rod 10 is provided with an inclined surface matched with the upper inclined surface of the wedge block 13 .

[0044] Since the inclined surface on the wedge block 13 is compatible with the inclined surface at the bottom end of the extrusion rod 10, when the extrusion rod 10 is inserted into the cross bar 3, it will overcome the elastic force of the second spring 15 and push the clamping rod 12 to be inserted into the reinforcement sleeve 4, the plug-in sleeve 6 and the plug-in rod 5 in sequence, thereby realizing the re-fixation of the vertical rod 1 and the vertical rod 2 2 from the inside, and increasing the vertical bearing tension at the connection between the vertical rod 1 and the vertical rod 2, so that the connection between the vertical rod 1 and the vertical rod 2 2 is more firm and stable.

[0045] Furthermore, a second elastic member is sleeved on the clamping rod 12 .

[0046] Furthermore, the first elastic member is a first spring 14, and the two ends of the first spring 14 are respectively connected to the inner wall of the placement groove and the arc plate 11, and the second elastic member is a second spring 15, and the two ends of the second spring 15 are respectively connected to the inner wall of the cavity and the wedge block 13.
