Description

Technical Field

[0001] The invention belongs to the technical field of building construction tool structures, and particularly relates to a device for fixing and connecting auxiliary scaffolding steel pipes. Background Art

[0002] Wall ties are components that reinforce the stability of other structures by connecting them to a secure fixed end. In construction projects, they are used to connect scaffolding to the main building structure and transmit tension and compression. The primary purpose of installing wall ties is to achieve a wall-attached connection, strengthen the overall stability of the scaffolding, increase its stable load-bearing capacity, and prevent major accidents such as toppling or collapse.

[0003] When fixing the scaffolding steel pipe to a wall that requires greater supporting force, it is necessary to drill a hole in the wall, insert the steel pipe into the hole, and then fix it with a locking key. The existing solution is generally to reserve a connector in the drilled hole by pouring concrete, and connect it to the scaffolding steel pipe through the connector. This connection method will make it impossible to remove the connector after the scaffolding is dismantled, and the connector will rust over a long period of time, which will have a structural impact on the wall. The existing solution will also directly set a clamping structure at both ends of the drilled hole with a structure with a clamping function. This structure requires manual operation on both sides of the wall during dismantling and installation, which is time-consuming and labor-intensive. Summary of the Invention

[0021] like Figures 1 to 4 As shown, the present invention discloses a device for fixing and connecting auxiliary scaffolding steel pipes, comprising a long rod 1, one end of which is provided with a flange front seat 2 for connecting with the steel pipe, and the other end of which is provided with a baffle 3 for rotation. Figure 2 、 Figure 3 As shown, the rotation axis of the baffle 3 is perpendicular to the axis of the long rod 1, and a counterweight 31 is provided at one free end of the baffle 3; Figure 4 As shown, three threaded holes 21 are evenly opened on the flange front seat 2, and the threaded holes 21 are connected to locking screws 22. When fixing the steel pipe, the long rod 1 is extended into the drilled hole opened in the wall, and the long rod 1 extends out of the drilled hole. When the baffle 3 is rotated and perpendicular to the axis of the long rod 1, the two free ends of the baffle 3 are blocked at the side edges of the drilled hole. The end of the scaffolding steel pipe is provided with a flange rear seat 4, and a through hole 41 is opened on the flange rear seat 4. The locking screw 22 passes through the through hole 41 and the threaded hole 21 in turn and rests on the wall. The locking screw 22 is also threadedly connected with a clamping nut 23, and the nut locks the flange rear seat 4 and the flange front seat 2.

[0022] In this structure, the fixed connection device of the steel pipe extends directly from one side of the wall. The long rod 1 is manually rotated so that the counterweight block 31 of the baffle 3 drives the baffle 3 to rotate downward, and the baffle 3 is formed into a vertical state with the horizontal plane. The long rod 1 is pulled back along the drilled hole, and the two edges of the baffle 3 can be blocked on the inside of the wall. By tightening the locking screw 22, the locking screw 22 is against the outside of the wall, and the long rod 1 can be fixed inside the drilled hole. Through the pressure of several locking screws 22, it can cope with walls of different roughness, so that the long rod 1 remains horizontal, ensuring that the seat flange has stable multi-point support, and continues to tighten the clamping nut 23. The clamping nut 23 and the flange front seat 2 will be fixed. The steel pipe can be connected to the long rod 1 by clamping the rear seat 4 of the flange. This structure does not require manual fixing and clamping of the wall and the steel pipe on both sides of the wall, and is quick to install. Compared with the fixing method of directly inserting the steel pipe into the drill hole and then clamping the parts, the long rod 1 and the steel pipe are divided into two sections. When inserting the steel pipe, there is no need to cause inconvenience in holding and fixing the steel pipe due to the excessive length of the steel pipe. When disassembling the long rod 1, loosen the locking screw 22, rotate the long rod 1, and under the action of the counterweight block 31, the baffle 3 rotates to a state where it does not block the drill hole and can be pulled out. This structure also does not need to pre-embed the fixed structure in the drill hole. No parts are left after disassembly, and the integrity of the drill hole is stronger after sealing.

[0023] In a further solution, Figure 1 and Figure 2 As shown, the long rod 1 includes a front tube 11 and a rear tube 12, the rear end of the front tube 11 is slidably arranged on the rear end of the rear tube 12, the baffle 3 is rotatably arranged at the front end of the front tube 11, and the flange front seat 2 is arranged at the front end of the rear tube 12. The rear end of the front tube 11 is closed and fixed with a threaded column 13, the threaded column 13 passes through the rear end of the rear tube 12, and a locking nut 14 is threadedly connected to the threaded column 13, and the locking nut 14 is against the front end of the rear tube 12.

[0024] This structure allows the long rod 1 to be extended and shortened to adapt to walls of different thicknesses. After the long rod 1 is fixed to the wall by the locking screw 22, the locking nut 14 can be further tightened to enhance the grip of the long rod 1 on the wall.

[0025] In a further solution, Figure 2 and Figure 4As shown, it also includes three tightening adjustment parts 15 arranged around the outside of the rear tube 12, and the tightening adjustment part 15 includes a wedge block 151 slidably arranged on the inner side of the front end of the rear tube 12, and the sliding direction of the wedge block 151 is perpendicular to the axis of the rear tube 12. The wedge block 151 is fixed with a counter-pin 152, which passes through the rear tube 12 and abuts against the side wall of the drilled hole. The end of the rear tube 12 is threadedly connected with a long stud 153, and the end of the long stud 153 is rounded. The moving direction of the long stud 153 extends along the axis of the rear tube 12, and the end of the long stud 153 abuts against the inclined surface of the wedge block 151, and the long stud 153 is screwed into to push the counter-pin 152 outward.

[0026] Since the long rod 1 needs to be inserted into the drill hole, the outer diameter of the long rod 1 is slightly smaller than the drill hole. The structure can adjust the three long studs 153 separately so that the three offset pins 152 are respectively against the side walls of the drill hole to adjust the inclination of the long rod 1 in the drill hole. The long rod 1 can also be positioned in the drill hole to prevent the long rod 1 from moving up and down. The adjusting component of the adjustment pin, that is, the long stud 153, can be set at the front end of the rear tube 12 through the wedge block 151 structure, and can also be easily adjusted and locked after the long rod 1 is inserted into the drill hole.

[0027] In a further solution, Figure 2 and Figure 3 As shown, two support plates 111 are provided at the front end of the front cylinder 11, and the baffle 3 is rotatably arranged between the two support plates 111. A limit block 112 is also provided between the two support plates 111, and a spring pin 113 is provided on the limit block 112. The spring pin 113 faces the free end of the baffle 3 where the counterweight block 31 is not provided.

[0028] In this structure, the two support plates 111 are used to support the baffle 3, and the limit block seat 112 is used to support the horizontal state of the block seat to prevent the baffle 3 from getting stuck in the drill hole when the long rod 1 is extended into the drill hole. When the long rod 1 is disassembled, the long rod 1 is rotated, and under the action of the spring pin 113, the baffle 3 is deflected from the vertical state, and then restored to the horizontal state under the action of gravity to cooperate with the recovery of the long rod 1.

[0029] In a further solution, Figure 2 and Figure 3 As shown, the rear end of the rear tube 12 is further provided with a guide column 121 , and the rear end of the front tube 11 is provided with a guide hole 114 that cooperates with the guide column 121 .

[0030] This structure is used to prevent relative rotation between the front cylinder 11 and the rear cylinder 12.

[0031] In a further solution, a long block 24 is fixedly provided on the side of the flange front seat 2. When the long block 24 is located at the lower side of the flange front seat 2, the baffle 3 rotates downward due to the gravity of the counterweight 31.

[0032] The long strip 24 serves as an auxiliary observation structure. When the long strip 24 is downward, the baffle 3 rotates downward under the action of the counterweight 31 to form a vertical blocking state. When the long strip 24 is upward, the long rod 1 has rotated 180°. This structure can assist the operator in extending the long rod 1 on one side of the wall, avoiding the baffle 3 from being in the wrong position due to the unknown rotation angle of the long rod 1.

[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
