Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of basket pull rods for cantilever scaffolds, and in particular to a pull rod type basket bolt with a slip monitoring component. Background Technology
[0002] As buildings become increasingly taller, cantilever scaffolding is being used more and more widely in construction. Traditional cantilever scaffolding typically involves reinforcing the cantilever beam with specialized pre-embedded steel bars, bolts, and plates, suspending it above the building's exterior. A tension layer is then established on the upper floor above the cantilever, and this tension layer is connected to the end of the cantilever beam furthest from the building using tie-rod type turnbuckles (e.g.,...). Figure 1 (As shown). However, existing pull-rod turnbuckles are composed of an upper screw, a lower screw, and a turnbuckle assembly. This results in a threaded connection between the turnbuckle assembly and the upper and lower screws. When this threaded connection is subjected to vibration, the tension load on the pull-rod turnbuckle fluctuates, causing slippage of the threads on the turnbuckle assembly and the upper and lower screws. This leads to changes in the distance between the upper and lower screws at their inner ends within the turnbuckle assembly. Therefore, monitoring the distance between the ends of the upper and lower screws within the turnbuckle assembly will help to monitor the stability of the pull-rod turnbuckle connection in a timely manner.
[0003] Currently, existing technologies have studied the stress conditions of tie-rod type turnbuckles to address the issue of monitoring the weight of the frame by which the tie rods in the turnbuckle do not bear the weight of the frame, thereby ensuring the overall stress distribution of the cantilever beam and improving safety. For example, the technical content disclosed in the tie-rod type turnbuckle cantilever frame tie rod stress monitoring device (patent number 202223149441.7) is relevant. However, existing technologies lack monitoring components to detect whether the upper and lower screws of the tie-rod type turnbuckle slip relative to each other during use. Therefore, our research team, based on practical construction experience, has installed a slip monitoring component between the upper and lower screws to monitor whether relative slippage occurs between them, thus providing a new structure for the tie-rod type turnbuckle. Utility Model Content
[0004] To address the aforementioned technical problems, this invention provides a tie-rod type turnbuckle with a slip monitoring component. The slip monitoring component is installed between the upper and lower screws. This component includes a slip element that can slide as the distance between the lower and upper screws changes. This allows for direct observation of the slip element's movement to determine the slip condition when stripping occurs due to vibration, thereby improving the efficiency of checking the stability of the tie-rod type turnbuckle connection after vibration of the cantilever frame.
[0005] The specific technical solution is as follows:
[0006] A pull rod type turnbuckle with a slip monitoring component includes a turnbuckle part, a lower screw rod, and an upper screw rod. The turnbuckle part includes a lower bolt and an upper bolt, and a plurality of turnbuckle rods are provided between the upper bolt and the lower bolt. The lower screw rod is threadedly connected to the lower bolt, and the upper screw rod is threadedly connected to the upper bolt. A slip monitoring component is provided between the upper screw rod and the lower screw rod, and the slip monitoring component includes a slip component that can slide as the distance between the lower screw rod and the upper screw rod changes.
[0007] To ensure the observability and measurability of the sliding distance, simplify the structure of the sliding assembly, and reduce installation difficulty, the sliding assembly preferably includes a sleeve and a rod. The sleeve has a sliding channel, and the cross-sectional shape of the sliding channel is the same as that of the rod. For example, when the cross-sectional shape of the sliding channel is square, the cross-sectional shape of the rod is also square, and the side length of the rod's cross-section is smaller than that of the sliding channel. The rod can slide freely within the sliding channel. The sleeve is fixedly connected to the end of the lower screw located inside the basket component, for example, by welding, and the rod is fixedly connected to the end of the upper screw located inside the basket component, for example, by welding.
[0008] To facilitate free sliding of the sleeve rod within the sleeve, preferably, the cross-section of the sleeve rod is circular, and the cross-section of the sliding channel is a circle with an inner diameter larger than the outer diameter of the sleeve rod.
[0009] To allow direct observation of the sliding distance, preferably, the sleeve is provided with a scale. More preferably, the scale is accurate to 0.1 mm.
[0010] In order to accurately position the end of the sleeve inside the turnbuckle on the sleeve rod after the pull rod type turnbuckle is installed, that is, the length of the positioning sleeve rod inserted into the sleeve, so as to directly observe the slippage by the distance between the positioning component and the end of the sleeve, preferably, the sleeve rod is provided with a positioning component, the positioning component can slide on the sleeve rod and be fixed in the corresponding position, and the positioning component is used to position the end of the sleeve near the upper screw on the sleeve rod.
[0011] More preferably, the positioning component is a collar sleeved on the sleeve rod, the collar being able to slide freely on the sleeve rod, and the collar being provided with a tightening bolt for tightening and fixing the collar to the sleeve rod.
[0012] More preferably, the positioning component includes a positioning member sleeved on the basket pole and a control member sleeved on the sleeve, wherein the positioning member and the control member are connected by a connecting rod; the positioning member can slide freely on the basket pole, and the positioning member is provided with a fixing member that can tighten and fix the positioning member on the basket pole; the control member is provided with a free channel through which the sleeve can pass.
[0013] More preferably, the positioning assembly includes a positioning member sleeved on the basket rod and a control member sleeved on the sleeve rod, wherein the positioning member and the control member are connected by a connecting rod; the positioning member can slide freely on the basket rod; the control member can slide freely on the sleeve rod, and the control member is provided with a tightening bolt, which is used to tighten and fix the control member on the sleeve rod.
[0014] Compared with the prior art, the technical effects of this invention are reflected in:
[0015] This invention features a simple structure and is easy to install. After the tie-rod turnbuckle is installed, the slip monitoring component can be directly welded between the upper and lower screws, enabling direct observation of the stripping phenomenon or severity of the tie-rod turnbuckle and improving the efficiency of checking the installation stability of the tie-rod turnbuckle.

[0024] To facilitate a correct understanding of the present invention by those skilled in the art, and to enable them to fully understand the technical content of the present invention, the technical solution of the present invention will be further described below in conjunction with specific embodiments. However, this description does not limit the scope of protection claimed by the present invention. Those skilled in the art should not limit the scope of protection of the present invention to the following description. Any equivalent substitutions or changes made by those skilled in the art or those familiar with the art based on the present invention, and based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
[0025] like Figure 1 As shown, in the prior art, when erecting a cantilever scaffold, the cantilever beam 6 is installed on the building using structural components such as bolts on the cantilever layer 5. Simultaneously, a tension layer 4 is determined above the cantilever layer 5, and a tensioning layer 4 is constructed using a basket-like component 1, a lower screw 2, and an upper screw 3. The basket-like component 1 includes a lower bolt 1.1 and an upper bolt 1.2, and several (e.g., three, four, five, etc., usually three) basket-like rods 1.3 are provided between the upper bolt 1.1 and the lower bolt 1.2. The material is usually steel bars. Both bolt 1.1 and lower bolt 1.2 are connected by welding or integral molding, referring to the corresponding structure in the prior art. The lower screw 2 is threadedly connected to the lower bolt 1.1, and the upper screw 3 is threadedly connected to the upper bolt 1.1. The tie rod type turnbuckle, which is formed by the matching connection of the upper screw 3 and the upper bolt 1.1, connects the tension layer 4 to the upper part of the cantilever beam 6 away from the building end. Then, uprights 7 are erected on the cantilever beam 6, and several horizontal bars are connected between the uprights 7 to form a cantilever scaffolding or cantilever frame structure. However, vibration often occurs during the use of the cantilever frame, causing stripping between the upper screw 3 and the upper bolt 1.1, and between the lower screw 2 and the lower bolt 1.2. This causes relative displacement between the upper screw 3 and the lower screw 2, resulting in a greater distance within the turnbuckle 1. This changes the stress on the tie rod type turnbuckle, affecting the overall safety. Therefore, after vibration occurs, it is necessary to check the connection of the pull rod turnbuckle. However, the existing technology cannot directly observe the slippage between the upper and lower screws, which requires turning the pull rod turnbuckle to adjust the tension during inspection, making the inspection difficult and inefficient.
[0026] Therefore, our research team has improved the existing tie-rod type turnbuckle structure, such as... Figure 2 As shown, a slippage monitoring component is provided between the upper screw 3 and the lower screw 2, and the slippage monitoring component includes a slippage component that can slide as the distance between the lower screw 2 and the upper screw 3 changes. This allows for a direct visualization of the relative slippage of the lower screw 2 and the upper screw 3 when the cantilever frame is subjected to vibration, enabling direct observation of whether slippage has occurred during inspection and improving inspection and maintenance efficiency.
[0027] like Figure 2 and Figure 3 As shown, in some embodiments, the sliding assembly includes a sleeve 8 and a rod 9. The sleeve 8 has a sliding channel 10, and the cross-sectional shape (e.g., square, rectangle, circle) of the sliding channel 10 is the same as the cross-sectional shape (e.g., square, rectangle, circle) of the rod 9. The rod 9 can slide freely within the sliding channel 10. The sleeve 8 is fixedly connected (e.g., welded) to the end of the lower screw 2 located within the turnbuckle 1, and the rod 9 is fixedly connected (e.g., welded) to the end of the upper screw 3 located within the turnbuckle 1. When vibration causes stripping, the distance between the end of the upper screw 3 and the end of the lower screw 2 located within the turnbuckle 1 changes, causing a change in the sliding position of the rod 9 within the sliding channel 10. By observing the position of the end of the sleeve 8 within the turnbuckle 1 on the rod 9, the length of the rod 9 inserted into the sliding channel 10 can be determined, directly revealing the change and improving inspection and maintenance efficiency. During installation and use, it should be ensured that the central axis of the sleeve rod 9 and the central axis of the sliding track 10 are on the same straight line. The sleeve rod 9 can be made of solid steel, hollow steel pipe, etc.; in a preferred embodiment, the sleeve 8 is made of steel pipe.
[0028] like Figure 3 and Figure 4 As shown, in some embodiments, the sleeve 9 has a circular cross-sectional shape, and the sliding track 10 has a circular cross-sectional shape with an inner diameter larger than the outer diameter of the sleeve 9. This improves the sliding effect of the sleeve 9 within the sliding track 10.
[0029] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the sleeve 9 is provided with a scale. In some preferred embodiments, the scale can be accurate to 0.1mm or 0.01mm. This allows for direct observation of the sliding situation and sliding distance, improving inspection efficiency.
[0030] In some embodiments, the sleeve 9 is provided with a positioning component, which can slide on the sleeve 9 and be fixed in a corresponding position. The positioning component is used to position the end of the sleeve 8 near the upper screw 3 on the sleeve 9. This ensures that after the pull-rod type turnbuckle is installed, the end of the sleeve 8 inside the turnbuckle 1 can be accurately positioned on the sleeve 9. This allows for direct observation of the distance between the positioning component and the end of the sleeve 8 when the upper screw 3 and lower screw 2 slip and move away, thus determining the slippage phenomenon and situation and improving inspection efficiency. In use, after the pull-rod type turnbuckle is installed, the positioning component is slid on the sleeve 9 until the end of the positioning component near the sleeve 8 is in close contact with the end of the sleeve 8, and then it is fixed. In this embodiment, it is ensured that the end of the sleeve 9 near the sliding channel 10 is located inside the sliding channel 10 or at the opening of the sliding channel 10.
[0031] In some embodiments, the positioning component is a collar sleeved on the sleeve rod 9. The collar is free to slide on the sleeve rod 9, and a tightening bolt is provided on the collar for tightening and fixing the collar to the sleeve rod 9. In use, the collar is slid until its end near the end of the sleeve 8 is flush with the end of the sleeve 8, and then fixed to the sleeve rod 9 using the tightening bolt. Furthermore, during installation, it should be ensured that the end of the sleeve rod 9 near the sliding track 10 is located within the sliding track 10 or is flush with the opening of the sliding track 10.
[0032] like Figure 4 and Figure 5 As shown, in some embodiments, the positioning assembly includes a positioning member 11 sleeved on the basket rod 1.3 and a control member 14 sleeved on the sleeve rod 9. The positioning member 11 and the control member 14 are connected by a connecting rod 13 (e.g., steel bar, steel material, etc.) (e.g., by welding). The positioning member 11 can slide freely on the basket rod 1.3, and the positioning member 11 is provided with a fixing member 12 that can tighten and fix the positioning member 11 on the basket rod 1.3. The control member 14 is provided with a free channel 15 through which the sleeve rod 9 can pass. After the pull rod type turnbuckle is installed, the sliding positioning part 11 drives the control part 14 to slide on the sleeve rod 9, so that the end of the control part 14 near the end of the sleeve 8 is close to the end of the sleeve 8. Then, the fixing part 12 is used to tighten and fix it on the turnbuckle 1.3. The sleeve rod 9 can pass through the free channel 15, so the distance of the end of the sleeve 8 away from the control part 14 can be observed to determine whether the lower screw 2 has slipped away or moved closer. At the same time, the distance between the control part 14 and the upper screw 3 can be combined to determine whether the upper screw 3 has slipped. Thus, it is possible to determine whether the stripping phenomenon occurs on the lower screw 2 or the upper screw 3, thereby improving the efficiency of inspection and maintenance.
[0033] like Figure 4 and Figure 5 As shown, in some embodiments, the positioning assembly includes a positioning member 11 sleeved on the basket rod 1.3 and a control member 14 sleeved on the sleeve rod 9. The positioning member 11 and the control member 14 are connected by a connecting rod 13. The positioning member 11 can slide freely on the basket rod 1.3. The control member 14 can slide freely on the sleeve rod 9, and the control member 14 is provided with a tightening bolt for tightening and fixing the control member 14 to the sleeve rod 9. This allows for the inspection of the relative distance slippage after the upper screw 2 and lower screw 3 have stripped, improving inspection and maintenance efficiency.
[0034] For any other matters not covered in this invention, they can be addressed by referring to existing technologies or common knowledge known to those skilled in the art, and by using conventional technical means.
