Description

Technical Field

[0001] This utility model belongs to the field of building equipment technology, specifically relating to a tool-type external wall steel wire rope tying device. Background Technology

[0002] In engineering fields such as building construction, bridge erection, and equipment installation, cantilever structures are widely used due to their advantages such as not occupying lower space and flexible layout. Among them, cantilevered I-beams, as core load-bearing components, are often used to support formwork, operating platforms, and scaffolding construction loads. To ensure the structural stability and load-bearing safety of cantilevered I-beams and avoid excessive deflection or overturning risks due to the load on the cantilever end, it is usually necessary to install tie-down or support devices for reinforcement and restraint. Currently, there are two main types of reinforcement methods for cantilevered I-beams. One type uses rigid support structures such as diagonal steel sections, which are fixed between the main structure and the I-beam by welding or bolting. However, this method has problems such as complex processing and installation, large material consumption, inconvenient disassembly, and high requirements for construction space, making it difficult to adapt to complex site environments. The other type is the wire rope tie-down method, which uses wire ropes to connect the cantilever end of the I-beam to the upper main structure, and the tensile strength of the wire ropes distributes the cantilever load. However, existing wire rope splicing devices are mostly temporary, piecemeal structures. The connection between the wire rope and the upper fixing point lacks dedicated and reliable prefabricated components, and often relies on on-site welding or binding, resulting in low installation efficiency and safety hazards. At the same time, existing wire rope fixing points are usually fixed structures, which cannot adapt to changes in different cantilever angles and splicing directions, leading to unreasonable stress on the wire rope and making it difficult to meet the safety and convenience requirements of engineering construction.

[0003] Chinese patent CN217711629U discloses a reusable steel cantilever frame wire rope tying device, including a pre-embedded sleeve in the top edge beam and a connecting mechanism detachably connected to the pre-embedded sleeve. The connecting mechanism is connected to a cantilevered I-beam via a wire rope, and the cantilevered I-beam is anchored to the bottom edge beam. This patent uses a pre-embedded sleeve and a detachable connection to set up the connecting mechanism, and uses wire ropes to tighten the cantilevered I-beam to form a tying device. This not only facilitates the installation and dismantling of the tying device, but also allows for reusability, and the structure does not damage the main structure of the building. It also increases the utilization rate of the tying points, reduces steel usage costs, and makes the tying points more stable and reliable. Disassembly and assembly are convenient, and the inspection process is easy to check for problems, improving construction efficiency. It is highly practical, easy to process, and has a high turnover rate. However, the U-shaped clamp in this patent needs to be clamped onto the top edge beam, making it mainly suitable for structures with standard edge beams. It cannot be directly applied to walls with external insulation boards, lacking versatility. Utility Model Content

[0004] The purpose of this utility model is to provide a tool-type external wall steel wire rope tying device to solve the problems of poor angle adaptability, cumbersome installation and disassembly, and insufficient versatility of existing steel wire rope fixing devices, so as to achieve flexible adjustment of the tying angle, stable and convenient installation, and ensure the stability of the cantilever structure and construction safety.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A tool-type external wall steel wire rope tying device is used for tying and fixing cantilevered I-beams installed on the exterior wall of a building with external insulation panels. It includes a tying main rod, one end of which is detachably fixed to the exterior wall. The other end of the tying main rod is fixedly provided with a hinge portion, which includes a bearing steel plate. A movable lifting ring is hinged to the surface of the bearing steel plate, and a through hole for threading a steel wire rope is provided on the movable lifting ring. A telescopic adjustable support is fixedly provided on the side of the bearing steel plate away from the movable lifting ring. The adjustable support includes two internal threaded sleeves fixedly connected to the bearing steel plate. A telescopic rod rotates within the internal threaded sleeves, and the telescopic direction of the telescopic rod is parallel to the axis of the tying main rod.

[0007] Furthermore, the supporting steel plate is arranged in a rectangular plate shape.

[0008] Furthermore, the movable lifting ring is D-shaped, comprising a curved arc portion and a straight connecting portion, which is hinged to the supporting steel plate via a hinge ring.

[0009] Furthermore, the end of the main tie rod furthest from the building's exterior wall is perpendicular to and fixedly connected to the surface of the supporting steel plate.

[0010] Furthermore, the end of the telescopic rod closest to the internal threaded sleeve is screwed into the internal threaded sleeve, while the end of the telescopic rod furthest from the internal threaded sleeve rests against the exterior wall of the building.

[0011] Furthermore, a locking nut is provided on the telescopic rod in conjunction with the internal threaded sleeve, and the end face of the locking nut abuts against the end of the internal threaded sleeve away from the bearing steel plate.

[0012] Furthermore, the end of the main tie rod away from the hinge is threaded through the exterior wall of the building and connected with a locking nut.

[0013] Furthermore, a gasket is installed between the locking nut and the building's exterior wall.

[0014] Furthermore, the diameter of the main tie rod is 20-30mm.

[0015] Furthermore, the diameter of the movable lifting ring cross-section is 15-25mm.

[0016] The beneficial effects of this utility model are as follows:

[0017] The movable lifting ring of this utility model is connected to the bearing steel plate through a hinge, and can rotate freely around the hinge point, allowing the wire rope to be flexibly adjusted according to the actual knot direction, realizing free adjustment of the knot angle and significantly improving the versatility of the device. The adjusting support adopts a telescopic design, and its extension length can be adjusted by rotating the telescopic rod, thereby adapting to external insulation boards of different thicknesses. During installation, the adjusting support can extend into the insulation board, and its end abuts against the building wall to provide stable support, making the installation process convenient and efficient. The overall structure of this device is reliable, effectively enhancing the anti-overturning and anti-deformation capabilities of the knot point, and ensuring the stability and safety of the cantilever structure under construction loads.

[0027] Example 1

[0028] like Figure 1-6As shown, the tool-type external wall steel wire rope tying device is used for tying and fixing the cantilevered I-beams 2 installed on the building exterior wall 1 with external insulation board. It includes a tying main rod 3, one end of which is detachably fixed to the building exterior wall 1, and the other end of which is fixedly provided with a hinge part. The hinge part includes a bearing steel plate 4, and a movable lifting ring 5 is hinged on the plate surface of the bearing steel plate 4. The movable lifting ring 5 has a through hole for threading the steel wire rope. A telescopic adjustable support 6 is fixedly provided on the plate surface of the bearing steel plate 4 away from the movable lifting ring 5. The adjustable support 6 includes two internal threaded sleeves 601 fixedly connected to the bearing steel plate 4. A telescopic rod 602 rotates inside the internal threaded sleeves 601. The telescopic direction of the telescopic rod 602 is parallel to the axis of the tying main rod 3.

[0029] The supporting steel plate 4 is arranged in a rectangular plate shape.

[0030] The movable lifting ring 5 is D-shaped in shape. The movable lifting ring 5 includes a curved arc part 501 and a straight connecting part 502. The connecting part 502 is hinged to the bearing steel plate 4 through the hinge ring 7.

[0031] The end of the main tie rod 3 away from the building's exterior wall 1 is perpendicular to and fixedly connected to the surface of the supporting steel plate 4.

[0032] The end of the telescopic rod 602 near the internal threaded sleeve 601 is screwed into the internal threaded sleeve 601, and the end of the telescopic rod 602 away from the internal threaded sleeve 601 abuts against the building's exterior wall 1.

[0033] A locking nut 8 is provided on the telescopic rod 602 in conjunction with the internal threaded sleeve 601. The end face of the locking nut 8 abuts against the end of the internal threaded sleeve 601 away from the bearing steel plate 4.

[0034] The end of the main tie rod 3 away from the hinge is connected to the building's exterior wall 1 with a locking nut 9.

[0035] A gasket is provided between the locking nut 9 and the building exterior wall 1.

[0036] The diameter of the main tie rod 3 is 20-30mm.

[0037] The diameter of the cross-section of the movable lifting ring 5 is 15-25mm.

[0038] Working process and principle:

[0039] I. Installation and Initial Fixing

[0040] Pre-drill holes for tie bolts on the exterior wall 1 of the building, and pass one end of the main tie rod 3 through the hole. On the inside of the exterior wall 1, insert washers in sequence and tighten the lock nuts 9 for initial fixation, so that the load-bearing steel plate 4, movable lifting ring 5 and adjusting support 6 of the device are located on the outside of the exterior wall 1.

[0041] II. Adjusting the length

[0042] Based on the actual thickness of the insulation board on the building's exterior wall 1, rotate the telescopic rod 602 so that it screws into or out of the threaded sleeve 601 until the distal end of the telescopic rod 602 can abut against the surface of the building's main structure. After adjustment, tighten the locking nut 8 on the telescopic rod 602 so that its end face is tightly against the end of the threaded sleeve 601, thereby locking the position of the telescopic rod 602 and forming a stable support.

[0043] III. Fastening and Connecting

[0044] On the inner side of the building's exterior wall 1, finally tighten the locking nut 9 to firmly anchor the main tie rod 3. During the tie-up process, connect one end of the wire rope to the cantilever end of the cantilevered I-beam 2, and pass the other end through the through hole of the movable lifting ring 5 and fix it in place. The movable lifting ring 5 can rotate freely around the hinge ring 7, automatically adapting to the wire rope tie-up direction and achieving angle adjustment.
