DETAILED DESCRIPTION

[0029] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 6 as shown in .

[0030] Embodiment 1: A wind-resistant high-altitude cantilever steel structure beam comprises a horizontally arranged cantilever steel beam 1, a wall connecting unit is welded to the right end of the cantilever steel beam 1, and the wall connecting unit is fixed to the building wall 2. A flexible anchor is installed above the cantilever steel beam 1, and a bottom support unit is installed below the cantilever steel beam 1. The right end of the flexible anchor and the right end of the bottom support unit are both fixedly connected to the building wall 2, and the left end of the flexible anchor and the left end of the bottom support unit are respectively connected to the top and bottom of a positioning sleeve, and the positioning sleeve is fixedly sleeved on the middle outer wall of the cantilever steel beam 1. An end positioning unit is also arranged on the right side of the positioning sleeve, and the end positioning unit is used to reinforce the end of the cantilever steel beam 1. The entire wind-resistant high-altitude cantilever steel structure beam is designed with a wall connection unit to fix the end of the cantilever steel beam 1. When fixing, the end positioning unit is used to complete the advanced end reinforcement connection, effectively ensuring the firmness of the end positioning; when the end is positioned and fixed, the middle upper end of the cantilever steel beam 1 is tensioned and tied to the wall through a flexible tie piece to ensure the upward pulling force, and at the same time, the bottom support unit below the middle is used to support the bottom of the entire cantilever steel beam 1. Multiple structural fixations are used to ensure the ability of the entire structure to resist wind loads and withstand cantilever torque during high-altitude cantilever installation, thereby ensuring the strength of the entire structure.

[0031] In any of the above schemes, it is preferred that the wall connection unit includes a wall connection main seat 3 fixedly welded to the right end face of the cantilever steel beam 1, and the right end face of the wall connection main seat 3 abuts against the building wall 2 and is fixed by a plurality of wall connection anchor bolts 4.

[0032] The main body of the wall connecting unit is fixed on the building wall 2 by means of the main wall connecting seat 3 in cooperation with various expansion type wall connecting anchor bolts 4, so as to finally achieve the purpose of stabilizing and fixing the right end of the entire cantilever steel beam 1.

[0033] In any of the above schemes, it is preferred that the positioning sleeve includes a first square steel tube 5 fixedly sleeved on the outer side wall of the cantilever steel beam 1, and a horizontal bolt 6 is arranged on the right side of the first square steel tube 5 and penetrates the first square steel tube 5 in the front and rear directions. A front locking nut 7 is screwed on the front end outer side wall of the horizontal bolt 6, and the front locking nut 7 abuts against the front side outer side wall of the first square steel tube 5. Vertical bolts 8 are arranged at intervals on the left side of the horizontal bolt 6, and the upper ends of the vertical bolts 8 pass from bottom to top to the top of the first square steel tube 5 and are locked in place by upper locking nuts 9. A first upper ear seat 10 and a first lower ear seat 11 are respectively welded on the upper and lower parts of the left side of the first square steel tube 5, and the first upper ear seat 10 is connected to the left end of the flexible tie member, and the first lower ear seat 11 is connected to the right end of the bottom support unit.

[0034] The main function of the positioning sleeve is to complete the positioning connection with the cantilever steel beam 1, and provide a stable installation and positioning foundation for the lower end installation of the flexible tie member and the lower end installation of the bottom support unit; when the entire first square steel pipe 5 is stably fixed, it relies on the horizontal bolts 6 and the vertical bolts 8 to complete the three-dimensional reinforcement and positioning of the entire structure, effectively ensuring the stability of the first square steel pipe 5.

[0035] When the first square steel tube 5 is positioned, the corresponding front locking nut 7 and upper locking nut 9 can be used to lock and fix the entire first square steel tube 5 on the outer wall of the corresponding cantilever steel beam 1. When the first square steel tube 5 is fixed, the first upper ear seat 10 and the first lower ear seat 11 can be stable, thereby facilitating stable positioning when connecting with the corresponding flexible tie member and bottom support unit.

[0036] In any of the above schemes, it is preferred that the flexible anchor member includes a flexible steel wire rope 12 that is inclined, the left side of the flexible steel wire rope 12 is inclined downward, the left lower end of the flexible steel wire rope 12 is fixedly connected to the first upper ear seat 10, and the right upper end of the flexible steel wire rope 12 is fixedly connected to the first wall connecting ear seat 13, and the first wall connecting ear seat 13 is fixed to the building wall 2.

[0037] In any of the above schemes, it is preferred that the bottom support unit includes an inclined side support rod 14, the upper end of the side support rod 14 is installed on the first lower ear seat 11, and the lower end of the side support rod 14 is installed on the second wall connecting ear seat 15, and the second wall connecting ear seat 15 is fixed on the building wall 2.

[0038] The flexible anchor as a whole mainly bears the tension, and can effectively use the flexible steel wire rope 12 to tighten the middle part of the entire cantilever steel beam 1 upward, thereby ensuring the stability of the cantilever steel beam 1 when the end is positioned in coordination.

[0039] Embodiment 2: Compared with Embodiment 1, this embodiment is different in that it further includes:

[0040] The angle between the side support rod 14 and the cantilever steel beam 1 is greater than the angle between the flexible steel wire rope 12 and the cantilever steel beam 1 .

[0041] Increasing the angle between the side support rod 14 and the cantilever steel beam 1 is mainly to better ensure its upward supporting effect on the cantilever steel beam 1, while at the same time being able to better extend to the left side to abut against the corresponding middle part of the cantilever steel beam 1 or the right position of the middle part, thereby ensuring the control of both the supporting position and the supporting effect.

[0042] In any of the above schemes, it is preferred that the end positioning unit includes a second square steel tube 16 fixedly sleeved on the outer side wall of the cantilever steel beam 1, and side wall columns 17 are symmetrically arranged above and below the second square steel tube 16, and the left ends of the two side wall columns 17 are respectively hinged on the ears welded at the corresponding positions of the second square steel tube 16, and the right ends of the two side wall columns 17 are respectively hingedly installed on the corresponding end wall ear seats 18, and each of the end wall ear seats 18 is anchored and fixed to the side wall of the building wall 2.

[0043] It should be noted that the end positioning unit mainly cooperates with the corresponding wall connecting unit to further strengthen and position the right end connection part or the near end part of the entire cantilever steel beam 1. When positioning, the side wall columns 17 set on the upper and lower sides can better complete the side support, so that a stable triangular support structure is formed between the side wall columns 17 and the building wall 2 and the cantilever steel beam 1, thereby improving the stability of the entire connection part; multi-point support enhances the supporting strength of the entire frame structure.

[0044] In any of the above schemes, it is preferred that a shifting seat 19 is integrally formed and fixedly connected on the outer side wall of the right end of the second square steel tube 16, and a main anti-slip plate 20 is arranged on the left side of the wall connecting main seat 3. The main anti-slip plate 20 is sleeved on the periphery of the head of each wall connecting anchor bolt 4 through the respective polyhedral main holes 25 arranged thereon to achieve limiting. The right side of the main anti-slip plate 20 abuts against the left side of the wall connecting main seat 3, and an anti-slip spring 21 is sleeved on the outer side wall of the cantilever steel beam 1 between the shifting seat 19 and the wall connecting main seat 3, and the left end of the anti-slip spring 21 abuts against the right side surface of the shifting seat 19, and the right end of the anti-slip spring 21 abuts against the left side surface of the main anti-slip plate 20.

[0045] It should be noted that the installed main anti-fall-off vertical plate 20, which is sleeved on the outer periphery of the head of each corresponding wall anchor bolt 4, can simultaneously control the head of each wall anchor bolt 4 from rotating, effectively preventing the entire wall anchor bolt 4 from rotating, thereby reducing the probability of loosening and falling off due to frequent wind load vibration.

[0046] In order to ensure the stability of the main anti-detachment vertical plate 20 and prevent it from moving horizontally and causing separation from the head of the wall anchor bolt 4, the rightward tightening force of the anti-detachment spring 21 is effectively ensured to effectively ensure its rightward tightening force, thereby effectively ensuring the fixing effect of the entire main anti-detachment vertical plate 20.

[0047] In any of the above solutions, it is preferred that the cantilever steel beam 1 is a square steel beam. The entire square steel beam can effectively ensure the structural strength of its beam body, and at the same time facilitate the installation and positioning of various components thereon, thereby reducing the probability of rotation.

[0048] In any of the above schemes, it is preferred that a horizontally arranged upper anti-slip plate 22 is sleeved on the periphery of the upper locking nut 9, and the upper anti-slip plate 22 is engaged with the outer wall of the upper locking nut 9 through a polygonal limiting hole 23 arranged on its left side, and a through rectangular hole 24 for sleeved on the periphery of the first upper ear seat 10 is arranged on the right side of the upper anti-slip plate 22.

[0049] The main function of the upper anti-slip plate 22 is to utilize the multi-prism limiting hole 23 provided thereon to cooperate with the outer side wall of the upper locking nut 9, thereby ensuring that the upper locking nut 9 will not rotate loose at will, thereby improving the anti-slip effect.

[0050] In addition, since the right side of the upper anti-slip plate 22 is also directly sleeved on the outer periphery of the first upper ear seat 10, the positioning of the two holes of the polygonal limiting hole 23 and the through rectangular hole 24 can effectively ensure the anti-rotation effect of the entire upper anti-slip plate 22, and effectively ensure the anti-rotation limiting effect of the entire structure on the upper locking nut 9.

[0051] It should be noted that during installation and construction, after each nut is installed, it is reinforced by spot welding to achieve further anti-loosening fixation with the bolts at the corresponding position.

[0052] Specific principle: The wind-resistant high-altitude cantilevered steel structure beam in this design is mainly designed by using wall connecting units to fix the end of the cantilevered steel beam 1.

[0053] The end positioning unit is used to complete the advanced end reinforcement connection, which can ensure the firmness of the end positioning.

[0054] When the end is positioned and fixed, the middle upper end of the cantilevered steel beam 1 is tensioned and tied to the wall through a flexible tie piece to ensure the upward tie force.

[0055] Furthermore, the bottom support unit at the bottom of the middle is used to support the bottom of the entire cantilever steel beam 1, and multiple structural fixations are used to ensure the ability of the entire structure to resist wind loads and withstand cantilever torque during high-altitude cantilever installation, thereby ensuring the strength of the entire structure. From the above, it can be seen that the overall structure of the wind-resistant high-altitude cantilever steel structure beam relies on the wall connection unit to complete the main positioning, and the support and positioning of the entire cantilever steel beam 1 are achieved under the dual effects of the flexible tie member and the bottom support unit, effectively improving the load resistance and wind resistance of the entire structure; the end positioning unit added at the end can achieve further reinforcement of the root of the cantilever steel beam 1 in both the upper and lower directions, effectively further improving the positioning stability of the root of the entire cantilever steel beam 1; the anti-slip spring 21 can be used to keep the main anti-slip vertical plate 20 against the right, effectively realizing the locking and positioning of each wall-connected anchor bolt 4, preventing it from rotating and loosening due to wind load vibration, and improving its anti-slip effect.

Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents.
