The right-angle vertices of the right-angled structures are chamfered. The left clamping plate and the inner clamping plate are positioned opposite each other, as are the outer clamping plate and the inner clamping plate. The left clamping plate, right clamping plate, outer clamping plate, and inner clamping plate abut against each other in pairs and are fixed with bolts, collectively forming a cross-shaped hollow structure. This hollow structure is used to house the tower body of the cross-jointed angle steel tower.

[0006] A first loading hole that communicates with each other is provided at the same position where the left clamping plate and the outer clamping plate abut together, and a second loading hole that communicates with each other is provided at the same position where the right clamping plate and the outer clamping plate abut together.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be further described in detail below with reference to specific examples and accompanying drawings. Exemplary embodiments will be described in detail here, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] A temporary loading point assembly for a cross-jointed angle steel tower includes a left clamping plate 1, a right clamping plate 2, an outer clamping plate 3, and an inner clamping plate 4, all of which are right-angled structures.

[0027] The right-angled structure has a chamfered vertex to avoid mismatch with the curvature of the angle steel on the tower body, improve the fit between the clamping plate and the angle steel on the tower body, and thus improve the clamping tightness between the clamping plate and the tower body, which is beneficial for stabilizing the loading of external forces.

[0028] The left clamping plate 1 and the inner clamping plate 4 are arranged opposite each other, and the outer clamping plate 3 and the inner clamping plate 4 are arranged opposite each other. The left clamping plate 1, the right clamping plate 2, the outer clamping plate 3 and the inner clamping plate 4 abut against each other and are fixed by fixing bolts 5, forming a cross-shaped hollow structure. The hollow structure is used to accommodate the tower body of the cross-jointed main material angle steel tower. Through the four detachable clamping plates, the loading point can be set at any position on the tower body, which is highly adaptable. Moreover, the hollow structure obtained by enclosure is a cross-shaped structure, which conforms to the characteristics of the commonly used angle steel material of the tower body, and the fit is higher, thus making the test results more accurate.

[0029] A first loading hole 6, which communicates with each other, is provided at the same position where the left clamping plate 1 and the outer clamping plate 3 abut. A second loading hole 7, which communicates with each other, is provided at the same position where the right clamping plate 2 and the outer clamping plate 3 abut. By using two loading holes, compared with applying force from one side, more combinations of force direction and magnitude can be applied, which is beneficial to the reliability of the test results.

[0030] This application may further include the following technical solution: Bolt washers 8 are provided at the abutment points of the left clamping plate 1, right clamping plate 2, outer clamping plate 3, and inner clamping plate 4. The bolt washers 8 have threaded holes for bolts to pass through, and their thickness is greater than the thickness of the angle steel tower body of the cross-jointed main material. The bolt washers 8 reduce the possibility of bolt stripping. Preferably, the washers are made of silicone, rubber, or other materials with a certain degree of elasticity and hardness. This also enhances the tightness of the fixed connection between the four clamping plates and prevents hard friction damage to the clamped tower body when the clamping plates are connected by bolts.

[0031] The application may further include the following technical solution: the left clamping plate 1 and the outer clamping plate 3 extend outward from the abutting point to form a first loading plate and a second loading plate, and the first loading plate and the second loading plate are provided with the first loading hole 6.

[0032] The right clamping plate 2 and the outer clamping plate 3 extend outward from their contact points to form a third loading plate and a fourth loading plate, respectively. The second loading hole 7 is provided on both the third loading plate and the fourth loading plate.

[0033] The application may further include the following technical solution: a first loading pad 11 and a second loading pad 12 are respectively provided between the first loading plate and the second loading plate, and between the third loading plate and the fourth loading plate, and the first loading pad 11 and the second loading pad 12 are respectively provided with a first loading hole 6 and a second loading hole 7.

[0034] This application may further include the following technical solution: the outer edges of the first and second loading plates are configured with rounded corners. The rounded corners reduce wear on loading components such as wire ropes.

[0035] This application may further include the following technical solution: anti-slip pads 9 are provided on the inner sides of the left clamping plate 1 and the right clamping plate 2, and the thickness of the anti-slip pads 9 is less than the thickness of the tower body of the cross-jointed main material angle steel tower. The anti-slip pads 9 can further reduce the sliding friction between the clamping plates and the tower body, and improve the stability of the fixed connection between the clamping plates and the tower body.

[0036] This application may further include the following technical solution: anti-slip pads 9 are provided on the inner sides of the outer clamping plate 3 and the inner clamping plate 4, and the thickness of the anti-slip pads 9 is less than the thickness of the tower body of the cross-jointed main material angle steel tower. The anti-slip pads 9 can be placed on the outer side of the angle steel of the clamped tower body or on the inner side of the angle steel of the clamped tower body.

[0037] This application may further include the following technical solution: the anti-slip pad 9 has a square structure, and one edge of the anti-slip pad 9 protrudes from the left clamping plate 1 or the right clamping plate 2. The anti-slip pad 9 is a cushioning pad with a certain degree of elasticity, such as rubber or silicone. In addition to its anti-slip effect, the protruding part can also protect the edge of the angle steel of the clamped tower body, reducing frictional damage between the edge of the angle steel of the clamped tower body and the protruding chamfer of the clamping plate.

[0038] This application may further include the following technical solution: stiffening plates 10 are provided on the inner sides of the right-angled structures of the left clamping plate 1, right clamping plate 2, outer clamping plate 3, and inner clamping plate 4. The stiffening plates 10 improve the stability of the clamping plate structure, thereby enhancing the stability and reliability of the test results during the loading experiment.

[0039] This application may further include the following technical solution: at least two stiffening plates 10 are provided, with the two stiffening plates 10 located at the upper and lower ends of the right-angle structure. Since the clamping plate is a single-piece structure similar to a V-shape, its outer surface is in complete contact with the tower body after being connected to it. The fit between the contact surface and the tower body surface has a significant impact on the test. Therefore, to ensure that the clamping plate maintains a right-angle and deformation-free state as much as possible, stiffening plates 10 are provided at least at the upper and lower ends of the clamping plate, which are prone to damage and deformation. This improves its stress stability and also facilitates the uniform application of force to the connected and fixed tower body after the loading hole is subjected to force, thereby improving the accuracy of the test results.

[0040] When in use, first install the left clamping plate 1, right clamping plate 2, inner clamping plate 4, and outer clamping plate 3 of the loading plate assembly onto the main tower body where the loading and hanging wires need to be applied; insert the first loading pad 11, the second loading pad 12, and the bolt washer 8 into the gap between the left clamping plate 1, right clamping plate 2, inner clamping plate 4, and outer clamping plate 3, then turn in the fixing bolt 5, confirm the position, and tighten to complete the installation; during the loading test, the loading test can be completed by connecting a steel wire rope to the first loading hole 6 and / or the second loading hole 7; after the test, remove the steel wire rope, loosen and remove the fixing bolt 5 used for fixing, complete the dismantling of the assembly, and collect and store it.
