[0029] Example 1

[0030] like Figure 1 to Figure 4 As shown, the utility model provides a technical solution:

[0031] A wall connecting member with adjustable length, which at least includes but is not limited to a connecting rod 1 and a limiting clamp 2; the end of the connecting rod 1 is provided with a non-return groove 11 and a connecting ring 12; the limiting clamp is provided with a spring member 21 for limiting the non-return groove 11 and a pulling member 22 connected to the connecting ring 12.

[0032] Based on the above structure, when in use, part of the structure of the limit clamp is embedded in the main structure before the concrete of the main structure is poured; the pulling member 22 is connected to the connecting ring 12, and the connecting ring 12 is driven to move along the length direction of the limit clamp through the action of the pulling member 22, and the spring member 21 limits the non-return slot 11 to prevent the limit clamp 2 from retracting, thereby ensuring the stability of the connection, and the connection rod 1 is adjusted by changing the fixed length of the connection rod 1 in the limit clamp. The connection rod 1 is connected to the scaffolding through the fastener 3 to achieve adjustment and fixation of the scaffolding.

[0033] As an example, the connecting rod 1 may include a rod body 13 and a slot portion 14. The rod body 13 is a cylindrical structure as a whole. The slot portion 14 is arranged at one end of the rod body 13. The anti-return slot 11 is evenly arranged in multiple numbers along the length direction of the slot portion 14. The connecting ring 12 is arranged on the end of the slot portion 14 away from the rod body 13.

[0034] Based on the above structure, the rod body 13 is set to a cylindrical structure, which can facilitate the fastener 3 to be quickly connected thereto, and the anti-return slot 11 is set to multiple, so that the slot part 14 itself has a certain length, which is convenient for adjustment within a predetermined length range.

[0035] As an example, the limit clamp 2 may include a main sleeve 23 and a connecting plate 24, wherein the connecting plate 24 is arranged on a side wall of the main sleeve 23 close to the pulling member 22, and the spring member 21 is arranged on an end of the main sleeve 23 away from the pulling member 22; at least two spring members 21 are arranged at circumferential positions of the main sleeve 23;

[0036] The connecting plate 24 is provided with fixing screw holes 25; the fixing screw holes 25 are arranged in at least two rows, a filling sleeve 26 is arranged at the bottom of the connecting plate 24, the filling sleeve 26 is arranged to match the number of the fixing screw holes 25, and a U-shaped embedded part 27 is arranged in each row of the filling sleeve; the length of the U-shaped embedded part 27 is not less than the length of the filling sleeve 26, and an external thread may be arranged at the end of the U-shaped embedded part 27;

[0037] The end of the U-shaped embedded part 27 passes through the filling sleeve 26 and the fixing screw hole 25 and is connected to the nut to form a stable structure.

[0038] Based on the above structure, when in use, multiple U-shaped embedded parts 27 are set in the cast body, and then the end of the U-shaped embedded part 27 is passed through the filling sleeve 26, and the nut is tightened to make the end of the filling sleeve 26 contact with the interface of the cast body, and finally a stable connection structure is formed. The U-shaped embedded part 27 is the basis of the overall structure and provides support for the whole.

[0039] As an example, the spring member 21 may include an articulated seat 211, a check rod 212, a spring seat 213 and a spring body 214; the articulated seat 211 and the spring seat 213 are both arranged on the side wall of the main sleeve 23, the articulated seats 211 are arranged in pairs, and the check rod 212 is arranged between adjacent articulated seats 211; the check rod 212 can rotate relative to the articulated seat 211, and the spring body 214 is arranged between the spring seat 213 and the check rod 212.

[0040] Based on the above structure, the anti-return rod 212 is pulled by the spring body 214 to keep it in an inclined state when it is stationary. When the limit clamp 2 passes through the anti-return rod 212 and is inserted into the main sleeve 23, the anti-return rod 212 resists the anti-return slot 11, so that it can only move in one direction.

[0041] As an example, the center line between the spring seat 213 and the adjacent hinge seat 211 is colinear, a support rod 215 is provided at the center position of the check rod 212, the support rod 215 is inserted into the hinge hole on the hinge seat 211, and a connecting seat 216 is provided at the end of the check rod 212 away from the main sleeve 23; one end of the spring body 214 is connected to the connecting seat 216, and the other end is connected to the spring seat 213.

[0042] Based on the above structure, setting the connecting seat 216 at the end of the anti-return rod 212 can increase the torque and improve the pulling force of the spring on the anti-return rod 212.

[0043] As an example, a threaded hole 28 and a locking bolt 29 can be provided in the length direction of the main sleeve 23; the threaded hole 28 protrudes from the side wall of the main sleeve 23 and penetrates the side wall of the main sleeve 23, and an internal thread is provided on the inner wall of the threaded hole 28, and the end of the locking bolt 29 can be screwed into the main sleeve 23 through the threaded hole 28.

[0044] The size of the locking bolt 29 is matched with the size of the anti-return slot 11 so that it can be inserted into the anti-return slot 11 to limit its position.

[0045] As an example, the threaded sleeve holes 28 can be arranged in a plurality of groups along the length direction of the main sleeve 23 , and each group of threaded sleeve holes 28 is provided with a plurality of threaded sleeve holes 28 along the circumferential position of the main sleeve 23 .

[0046] Based on the above structure, when in use, the connecting rod 1 is initially locked by a spring to prevent the connecting rod 1 from retracting, and then the connecting rod 1 is locked for a second time by inserting multiple locking bolts 29 into the anti-return groove 11. Through two lockings, the stability of the connection can be guaranteed.

[0047] As an example, the pulling member 22 may include a handwheel 221, a rotating rod 222, a rope clamp 223 and a rope clamp ring 224; the rotating rod 222 is arranged to pass through the main sleeve 23, and a rotating bearing 225 may be arranged on the contact portion between the rotating rod 222 and the main sleeve 23; the handwheel 221 is arranged at the end of the rotating rod 222, the rope clamp 223 is arranged at the center position of the rotating rod 222, and the rope clamp ring 224 is arranged on the rope clamp 223.

[0048] Based on the above structure, when in use, the steel rope is passed through the steel rope clamp ring 224 and the connecting ring 12 to connect the two as a whole, and then the steel rope is retracted on the steel rope clamp wheel 223 by rotating the hand wheel disk 221, so that the connecting rod 1 gradually moves to one side, so that the position of the rod body 13 can be accurately adjusted and locked.

[0049] The construction method of the wall connecting member with adjustable length in this embodiment is as follows:

[0050] (1) Installation of fixed embedded parts

[0051] Two steel bars need to be placed vertically above the bottom of the fixed embedded part to fix the embedded part and the steel bars to prevent the fixed embedded part from deflecting when subjected to forces in other directions;

[0052] (2) Wall connection adjustment method

[0053] After the adjustable wall connection is installed, keep the fixing bolts in a non-tightened state, use the fastener 3 to connect and fix it to the external scaffolding, use an electric wrench to operate the adjustment device to adjust the external scaffolding, and the connecting frame rod is deeply inserted into the main sleeve. The non-return slot 11 passes through the non-return device to prevent the connecting frame rod from slipping.

[0054] (3) Wall connection fixing method

[0055] When the external scaffolding is in a safe state, the connecting frame rods are tightened with fixing bolts to form a rigid connection between the external scaffolding, the connecting frame rods, the main sleeve, the fixed embedded parts, and the main structure of the building to ensure the stability of the external scaffolding.

[0056] This solution is used in housing construction projects. By fixing the embedded parts embedded in the main structure and adjusting the rods connecting the frame, the verticality of the external scaffolding is adjusted. To a certain extent, it solves the problem that the distance between the external scaffolding and the main structure is inconvenient to adjust during the erection of the external scaffolding. In the process of using the wall connection parts with adjustable length for construction, the collapse of the external scaffolding is reduced, ensuring the safe production of the project and the life safety of the construction workers.
