Description

Technical Field

[0001] The utility model relates to the technical field of construction devices, and particularly relates to a waterproof safety belt hanging point device for a tie rod sleeve. Background Art

[0002] At the present stage, construction site safety is particularly important. However, there are few available safety belt hanging points on the outer facade of the main structure. During the formwork reinforcement process of cast-in-place concrete components such as columns, beams, and walls in the main structure construction stage, tie rods are used for reinforcement, and tie rod sleeves need to be used in supporting the tie rods. After the formwork is removed after concrete pouring, the sleeves will remain permanently in the concrete components. Since the sleeves penetrate through the concrete components, they will become weak points for leakage on the outer facade of the main structure. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a waterproof safety belt hanging point device for a tie rod sleeve, and the technical scheme adopted is as follows:

[0004] A waterproof safety belt hanging point device for a tie rod sleeve, characterized in that it comprises:

[0005] A threaded sleeve, with a hanging point ring detachably connected to one axial end, and an internal threaded hole with a length distributed along the axial direction of the threaded sleeve provided at the other end;

[0006] A connecting screw, with one axial end threadedly connected to the internal threaded hole, and a fixed baffle fixedly connected to the other end, and a sliding baffle also slidably connected to the connecting screw;

[0007] An expansion rubber ring, coaxially sleeved outside the connecting screw and located between the fixed baffle and the sliding baffle.

[0008] Furthermore, multiple groups of sliding baffles are provided, and expansion rubber rings are provided between the fixed baffle and the sliding baffles and between adjacent groups of sliding baffles.

[0009] Furthermore, an installation screw is fixedly connected to the end of the threaded sleeve away from the screw, a nut is fixedly connected to the hanging point ring, and the nut is threadedly connected to the installation screw.

[0010] Furthermore, multiple groups of protrusions are axially provided on the outer surface of the expansion rubber ring.

[0011] Furthermore, the outer diameter of the expansion rubber ring in the uncompressed state is less than or equal to the outer diameters of the fixed baffle and the sliding baffle.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. Axially adjust the threaded sleeve and the connecting rod to squeeze and expand the rubber ring. The rubber ring is squeezed and expanded between the fixed baffle and the sliding baffle, so that the rubber ring generates frictional force with the inner wall of the external wall screw hole, thereby realizing the fixation and waterproofing of the screw hole. The original screw hole of the external wall can be used without additional drilling.

[0014] 2. Multiple groups of expansion rubber rings are arranged at intervals, which is convenient for installation and replacement.

[0015] 3. Multiple groups of protrusions are arranged on the outer surface of the expansion rubber ring, which can effectively improve the frictional force between the rubber ring and the inner wall of the screw hole, thereby improving the fixing effect.

[0016] 4. The hanging point ring is connected to the installation screw through a nut, and then fixedly connected to the threaded sleeve, which is convenient for disassembly and the hanging point ring can be reused.

[0017] 5. The outer diameter of the expansion rubber ring in the uncompressed state is less than or equal to the outer diameters of the fixed baffle and the sliding baffle, which can reduce the friction between the expansion rubber ring and the inner wall of the tension rod sleeve during installation and facilitate installation.

Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0024] In the description of the utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the view direction or positional relationship, and is only for the convenience of describing the utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the utility model.

[0025] Such as Figures 1 - 3 The waterproof safety belt hanging point device for the tie rod sleeve shown in the figure includes a threaded sleeve 1, a connecting screw rod 2, an expansion rubber ring 3, a fixed baffle 4, a sliding baffle 5, and a hanging point ring 8.

[0026] Specifically, the threaded sleeve 1 has a sleeve structure with a hollow interior and internal threads. The internal threads are distributed left and right along the axial direction of the threaded sleeve 1 and penetrate through the left end of the threaded sleeve 1. An installation screw rod 6 is fixedly connected to the right end of the threaded sleeve 1. A nut 7 is fixedly connected to the hanging point ring 8. The hanging point ring 8 can be connected to the threaded sleeve 1 through the threaded connection between the nut 7 and the installation screw rod 6, and the relative positional relationship between the hanging point ring 8 and the threaded sleeve 1 can be adjusted.

[0027] The right end of the connecting screw rod 2 is threadedly connected to the internal threaded hole of the threaded sleeve 1, and the two are coaxially distributed. The axial relative position between the threaded sleeve 1 and the connecting screw rod 2 can be adjusted through threaded connection. A fixed baffle 4 is fixedly connected to the left end of the connecting screw rod 2. In addition, a plurality of sliding baffles 5 are slidably connected to the connecting screw rod 2. The sliding baffles 5 can move along the axis direction of the connecting screw rod 2. Expansion rubber rings 3 are arranged between the fixed baffle 4 and the sliding baffles 5 and between two adjacent groups of sliding baffles 5. The expansion rubber rings 3 are coaxially sleeved outside the connecting screw rod 2.

[0028] In addition, in this embodiment, a plurality of groups of protrusions are arranged on the outer surface of the expansion rubber ring 3 along the axial direction. This structure can increase the friction force and waterproof effect between the deformed expansion rubber ring 3 and the inner wall of the wall bolt hole. The outer diameter of the expansion rubber ring 3 in the unextruded state is equal to the outer diameters of the fixed baffle 4 and the sliding baffle 5. The setting of this structure can reduce the friction force between the expansion rubber ring 3 and the inner wall of the tie rod sleeve during installation.

[0029] The working principle of this device is as follows:

[0030] During construction, first, the expansion rubber ring 3 and the sliding connection plate 5 are sleeved on the connecting screw rod 2 at intervals. The right end of the connecting screw rod 2 is connected to the threaded sleeve 1. Then, the above structure is inserted into the screw hole of the exterior wall from one end of the fixed baffle 4. The right end of the threaded sleeve 1 extends out of the exterior wall screw hole by a certain length. At this time, the threaded sleeve 1 is rotated by a socket wrench to squeeze the expansion rubber ring 3, so that the expansion rubber ring 3 is in close contact with the inner wall of the exterior wall screw hole, thus achieving the fixing and waterproofing effects. After adjustment, the hanging point ring 8 is connected to the mounting screw rod 6 through the nut 7. The hanging point ring 8 can be used for single-point hanging of a safety belt or for hanging a safety rope. After use, the hanging point ring 8 can be removed and reused.

[0031] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
