Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a connecting fastener for engineering building scaffolding. Background Technology

[0002] Construction scaffolding is a temporary structure used in construction to support workers and materials, ensuring safe and efficient construction. Fasteners are key components used to secure the scaffolding, ensuring its stability and safety.

[0003] There are many types of scaffolding connecting couplers on the market. For example, a scaffolding connecting coupler with publication number CN220814876U is disclosed on the China Patent website. This coupler can be used for scaffolding connection, but it has some defects and shortcomings that need to be improved: (1) Due to structural design reasons, some existing scaffolding connecting couplers have poor flexibility and adaptability. When the coupler connects the scaffolding steel pipes, the connection direction of the steel pipes is often fixed and difficult to adjust, thus failing to meet complex construction needs; (2) Most existing scaffolding connecting couplers are fastened by the mutual cooperation between bolts and nuts. The fastening method is relatively simple. Under long-term use or vibration and impact, the bolts and nuts are prone to loosening, which leads to the failure of the scaffolding coupler connection; (3) Some existing scaffolding connecting couplers have limited load-bearing capacity and lack effective reinforcement measures. Under high load or complex stress conditions, the coupler is prone to deformation or breakage, thus affecting its service life. Therefore, in view of the above problems, the engineering construction scaffolding connecting coupler provided by this utility model is of great significance. Utility Model Content

[0004] This utility model provides a connecting fastener for engineering construction scaffolding. By tightening the adjusting nut, the fixed angle between the two fixed seats can be adjusted through the interaction between the adjusting nut and the adjusting rod, allowing the scaffolding steel pipe to adjust its direction within a certain angle range. This effectively improves the flexibility and adaptability of the connecting fastener, enabling it to meet different construction needs. The connecting fastener can be initially tightened by the interaction between the first fastening rod 7 and the first fastening nut 8. The connecting fastener can be further tightened by the interaction between the locking block, the second fastening rod, and the second fastening nut. Compared with a single tightening method, this effectively prevents the connecting fastener from failing due to loosening of the first fastening rod and the first fastening nut during long-term use or when subjected to vibration or impact. The reinforcing ribs and multiple reinforcing blocks can respectively reinforce the fixed seat and the movable seat, thereby improving the structural strength and load-bearing capacity of the fixed seat and the movable seat, and preventing deformation or breakage under high load or complex stress conditions. In summary, this solves the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] Furthermore, a protective pad is provided on the arc-shaped inner wall surface of both the fixed seat and the movable seat.

[0011] Furthermore, the top and bottom outer walls of the fixing base are both fixedly connected with reinforcing ribs, which are triangular in shape and whose bottoms are fixedly connected to the fixing base.

[0012] Furthermore, a number of reinforcing blocks are fixedly connected to the outer wall of the movable seat. The reinforcing blocks are arc-shaped strips and are distributed in an equidistant ring along the arc surface of the movable seat.

[0013] The present invention has the following advantages over the prior art:

[0014] (1) When using the engineering construction scaffolding connecting fastener of this utility model, the fixed angle between the two fixed seats can be adjusted by tightening the adjusting nut and the adjusting rod, so that the scaffolding steel pipe can be adjusted within a certain angle range, thereby effectively improving the flexibility and adaptability of the connecting fastener and enabling it to meet different construction needs.

[0029] Please see Figure 1-6As shown, this utility model discloses a connecting fastener for construction scaffolding, comprising a pair of fixed seats 1 and a pair of movable seats 2. The inner side of the fixed seat 1 is arc-shaped and has a groove 3. An adjustment hole 4 is provided at the bottom of the groove 3, and an adjustment rod 5 is inserted into the adjustment hole 4. The rod body of the adjustment rod 5 is provided with external threads and is threadedly connected to an adjusting nut 6 that matches it. The top and bottom inner walls of the fixed seat 1 are both fixedly connected with a first fastening rod 7. The rod body of the first fastening rod 7 is provided with external threads and is threadedly connected to a first fastening nut 8 that matches it. The inner side of the movable seat 2 is arc-shaped, and both its top and bottom ends have fastening holes 9. When it is necessary to connect the scaffolding, the two scaffolding steel pipes to be connected can be... The movable seat 2 is inserted into and fitted onto the inner arc-shaped surface of the fixed seat 1 to ensure that the scaffolding steel pipe is in close contact with the fixed seat 1. Then, by tightening the first fastening nut 8, a fastening force can be applied to fix the movable seat 2 onto the fixed seat 1, so that the scaffolding steel pipe is in close contact with the movable seat 2. This completes the connection and fastening of the scaffolding. The two fixed seats 1 can rotate between each other. By tightening the adjusting nut 6, the fixed angle between the two fixed seats 1 can be adjusted through the cooperation between the adjusting nut 6 and the adjusting rod 5, so that the scaffolding steel pipe can be adjusted within a certain angle range. This effectively improves the flexibility and adaptability of the connecting fastener, enabling it to meet different construction needs.

[0030] The diameter of the fastening hole 9 is equal to the diameter of the first fastening rod 7, and the center of each fastening hole 9 corresponds one-to-one with the center of each first fastening rod 7. The first fastening rod 7 can be aligned and passed through the corresponding fastening hole 9 so that the movable seat 2 can be installed and fixed on the fixed seat 1. Then, the connection fastener can be initially fastened by the mutual cooperation between the first fastening rod 7 and the first fastening nut 8.

[0031] The first fastening rod 7 is fitted with a washer 10, which is located between the first fastening rod 7 and the first fastening nut 8. The inner diameter of the washer 10 corresponds to the diameter of the first fastening rod 7, and the surface of the washer 10 is provided with herringbone anti-slip texture. The washer 10 can be installed between the first fastening rod 7 and the first fastening nut 8 to distribute pressure, thereby preventing the first fastening rod 7 and the first fastening nut 8 from being damaged by excessive tightening force on the fixed seat 1 and the movable seat 2. At the same time, the anti-slip texture on the surface of the washer 10 can increase the friction between the washer 10 and the first fastening rod 7 and the first fastening nut 8, thereby preventing the first fastening rod 7 and the first fastening nut 8 from loosening due to vibration or load changes.

[0032] The fixed base 1 and the movable base 2 are both equipped with locking blocks 11 at their top and bottom, and are also fixedly connected to the top and bottom of the fixed base 1 and the movable base 2 with second fastening rods 12. The rods of the second fastening rods 12 are provided with external threads and are threadedly connected to a second fastening nut 13 that mates with them. The locking blocks 11 are provided with locking grooves 14, which are rectangular and whose width corresponds to the diameter of the second fastening rod 12. After the connecting fastener is initially tightened by the cooperation between the first fastening rod 7 and the first fastening nut 8, the locking blocks 11 can be installed on the fixed base 1. The first fastening rod 7 and the first fastening nut 8 are tightened at the top and bottom of the movable seat 2, so that each second fastening rod 12 passes through and fits against the groove wall of the locking groove 14. Then, by tightening the second fastening nut 13, a fastening force can be applied to fix the locking block 11 on the fixed seat 1 and the movable seat 2 until the locking block 11 is in close contact with the top and bottom surfaces of the fixed seat 1 and the movable seat 2. This allows for secondary fastening of the connecting fastener. Compared with a single fastening method, this can effectively prevent the connection of the scaffolding fastener from failing due to the loosening of the first fastening rod 7 and the first fastening nut 8 when the connecting fastener is used for a long time or subjected to vibration and impact.

[0033] The fixed seat 1 and the movable seat 2 are both provided with a protective pad 15 on their arc-shaped inner wall surfaces. The protective pad 15 can be made of elastic materials such as sponge and is fixed by means of glue. When the scaffold steel pipe is attached to the arc-shaped inner wall of the fixed seat 1 and the movable seat 2, the protective pad 15 can play a wear-resistant buffering role to prevent the surface of the steel pipe from being worn due to direct contact with the fixed seat 1 and the movable seat 2.

[0034] The top and bottom outer walls of the fixed base 1 are both fixedly connected with reinforcing ribs 16. The reinforcing ribs 16 are triangular and their bottoms are fixedly connected to the fixed base 1. The fixed base 1 can be reinforced by the reinforcing ribs 16 to improve the structural strength and load-bearing capacity of the fixed base 1, thereby preventing it from deforming or breaking under high load or complex stress conditions.

[0035] Among them, the outer wall of the movable seat 2 is fixedly connected with several reinforcing blocks 17. The reinforcing blocks 17 are arc-shaped strips and are distributed in an equidistant ring along the arc surface of the movable seat 2. The movable seat 2 can be reinforced by multiple reinforcing blocks 17 to improve the structural strength and load-bearing capacity of the movable seat 2, thereby preventing it from deforming or breaking under high load or complex stress conditions.

[0036] All standard parts used in the application documents can be purchased from the market. All components in this application documents can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

[0037] The working principle of this utility model is as follows:

[0038] In use, the two scaffolding steel pipes to be connected can be inserted and fitted onto the inner arc-shaped surface of the fixed base 1 to ensure tight contact between the scaffolding steel pipes and the fixed base 1. Then, tightening the first fastening nut 8 applies a tightening force to fix the movable base 2 onto the fixed base 1, ensuring tight contact between the scaffolding steel pipes and the movable base 2. This completes the connection and fastening of the scaffolding. The two fixed bases 1 can rotate. By tightening the adjusting nut 6, the fixing angle between the two fixed bases 1 can be adjusted through the interaction between the adjusting nut 6 and the adjusting rod 5, allowing the scaffolding steel pipes to adjust their direction within a certain angle range. This effectively improves the flexibility and adaptability of the connecting fastener, enabling it to meet different construction needs. The connecting fastener is initially tightened through the interaction between the first fastening rod 7 and the first fastening nut 8. Further tightening is achieved through the interaction between the first fastening rod 7 and the first fastening nut 8. After the fastener is initially tightened by mutual cooperation, the locking blocks 11 can be installed on the top and bottom of the fixed seat 1 and the movable seat 2 respectively, so that each of the second fastening rods 12 passes through and fits against the groove wall of the locking groove 14. Then, by tightening the second fastening nut 13, a tightening force can be applied to fix the locking blocks 11 on the fixed seat 1 and the movable seat 2 until the locking blocks 11 are in close contact with the top and bottom surfaces of the fixed seat 1 and the movable seat 2. This allows for a secondary tightening of the fastener. Compared with a single tightening method, this can effectively prevent the connection of the scaffolding fastener from failing due to the loosening of the first fastening rod 7 and the first fastening nut 8 during long-term use or when subjected to vibration or impact. The fixed seat 1 and the movable seat 2 can be reinforced by the reinforcing ribs 16 and multiple reinforcing blocks 17 respectively, so as to improve the structural strength and load-bearing capacity of the fixed seat 1 and the movable seat 2, thereby preventing them from deforming or breaking under high load or complex stress conditions.
