DETAILED DESCRIPTION

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example

[0035] like Figures 1-5 As shown, the lifeline fixing ring structure disclosed in this embodiment of the invention includes a main fixing support plate 1 and a secondary fixing support plate 2 arranged symmetrically, as well as a U-shaped anchor ring 3. The U-shaped anchor ring 3 passes through the secondary fixing support plate 2 and the main fixing support plate 1 in sequence, and a nut 4 is threadedly connected to the end of its open end. The main fixing support plate 1, the secondary fixing support plate 2 and the concrete structure 9 are fixed together by a single U-shaped anchor ring 3.

[0036] The above structure is simple and can reduce the operation time of drilling holes in the concrete structure 9 formwork and the number of sleeves 8 used, saving installation time and material usage during the installation process. Example

[0037] like Figures 1-5 As shown, the lifeline fixing ring structure disclosed in this embodiment of the invention includes a main fixing support plate 1 and a secondary fixing support plate 2 arranged symmetrically, as well as two U-shaped anchor rings 3. The U-shaped anchor rings 3 pass through the secondary fixing support plate 2 and the main fixing support plate 1 in sequence, and a nut 4 is threaded to the end of the opening end. The main fixing support plate 1, the secondary fixing support plate 2 and the concrete structure 9 are fixed together by the two U-shaped anchor rings 3.

[0038] The difference between the lifeline fixing ring structure in Embodiment 2 and the lifeline fixing ring structure in Embodiment 1 is that the double U-shaped anchor ring 3 is used, which can improve the stability of the main fixing support plate 1 and the secondary fixing support plate 2. The structures in Embodiment 1 and Embodiment 2 can be selected according to actual usage requirements. When there is a certain load-bearing capacity requirement, the structure in Embodiment 2 can be selected. Example

[0039] like Figures 1-4 As shown, the surface of the main fixed support plate 1 has an opening (not shown in the attached figure), and a threaded end 5 is coaxially provided at the opening on the outer surface of the main fixed support plate 1. The threaded end 5 is threadedly connected to a threaded ring 6.

[0040] In the above embodiments 1 to 3:

[0041] When implementing the process of installing the lifeline fixing ring structure using sleeve 8, the following installation mode can be adopted:

[0042] Mode 1: Install all lifeline fixing ring structures using sleeve 8, including main fixing support plate 1, secondary fixing support plate 2, U-shaped anchor ring 3 and threaded ring 6.

[0043] Compared with the prior art, the material waste caused by the material pre-buried in the concrete structure 9 cannot be reused.

[0044] Mode 2, install all the life rope fixing ring structures including the main fixing support plate 1, the auxiliary fixing support plate 2 and the U-shaped anchor ring 3 by using the sleeve 8, at this time, install part of the threaded rings 6 according to the construction process, and the remaining part is transported for use by disassembling the installed threaded rings 6 according to the construction process.

[0045] Compared with the prior art, the material waste caused by the material pre-buried in the concrete structure 9 cannot be reused, and the use of the threaded rings 6 can be reduced, and the installation and use can be flexibly arranged according to the construction area.

[0046] Mode 3, according to the construction process, install the main fixing support plate 1, the auxiliary fixing support plate 2 and the U-shaped anchor ring 3 in the area needing construction, at this time, install all the threaded rings 6, and the remaining construction is completed by transporting for use by disassembling the installed main fixing support plate 1, the auxiliary fixing support plate 2 and the U-shaped anchor ring 3 according to the construction process.

[0047] Compared with the prior art, the material waste caused by the material pre-buried in the concrete structure 9 cannot be reused, and the use of the threaded rings 6 and the main fixing support plate 1, the auxiliary fixing support plate 2 and the U-shaped anchor ring 3 can be reduced, and the use of materials can be saved.

[0048] Mode 4, according to the construction process, install the main fixing support plate 1, the auxiliary fixing support plate 2 and the U-shaped anchor ring 3 in the area needing construction, and the remaining construction is completed by transporting for use by disassembling the installed main fixing support plate 1, the auxiliary fixing support plate 2 and the U-shaped anchor ring 3 according to the construction process, at this time, install part of the threaded rings 6 according to the construction process, and the remaining part is transported for use by disassembling the installed threaded rings 6 according to the construction process.

[0049] Compared with the prior art, the material waste caused by the material pre-buried in the concrete structure 9 cannot be reused, and the use of the threaded rings 6 and the main fixing support plate 1, the auxiliary fixing support plate 2 and the U-shaped anchor ring 3 can be reduced, and the use of materials can be saved.

[0050] As shown in Figures 2-5 The threaded ring 6 includes a screw rod 62 threadedly connected with the threaded end 5, a buckle ring 61 connected with one end of the outer side of the screw rod 62, and a clamping groove 621 arranged on the one end of the outer side of the screw rod 62.

[0051] In contrast, a locking structure 7 is provided to lock the position of the threaded ring 6 to prevent it from coming out. The locking structure 7 includes a card 71 and an elastic ball 72. The card 71 is inserted into the insertion hole 11, and the elastic ball 72 is disposed in the blind hole 111. The elastic ball 72 is used to fix the position of the card 71, and the card 71 is used to fix the position of the threaded ring 6. The main fixing support plate 1 has an insertion hole 11 that penetrates its side wall, and at least one blind hole 111 is provided on the same side of the side wall of the insertion hole 11.

[0052] Specifically, the card 71 has a through hole a711 and a through hole b712 that are interconnected. The through hole a711 can accommodate the lead screw 62 to pass through, and the through hole b712 is used to engage with the card slot 621 to fix the position of the threaded ring 6.

[0053] The above-mentioned locking process includes:

[0054] 1. Unlocked status:

[0055] At this time, when the card 71 is moved to the unlocked state, the opening on the surface of the main fixed support plate 1 is coaxial with the through hole a711 on the card 71, and the screw 62 of the threaded ring 6 can freely pass through the through hole. Rotating the threaded ring 6 at will can drive it to extend or retract the threaded end 5.

[0056] 2. Locked state:

[0057] The screw 62 of the threaded ring 6 needs to be fully rotated and retracted into the threaded end 5. At this time, the card 71 is moved to the locked state. The axis of the opening on the surface of the main fixed support plate 1 is offset from the axis of the through hole a711 on the card 71. The slot 621 and the through hole b712 are engaged together. The card 71 abuts against the screw 62, fixing the position of the screw 62. No matter how the threaded ring 6 is rotated, it cannot be driven to extend or retract into the threaded end 5, thus fixing its position.

[0058] like Figure 5 As shown, in order to facilitate identification of the current state of the lifeline fixing ring structure, the surface of the card 71 is provided with a recessed mark 714. The recessed mark 714 serves two purposes: firstly, it acts as an identifier; secondly, its recessed structure enhances the friction of the card 71, making it easier to slide the card 71 inside the socket 11.

[0059] In another embodiment, the recessed mark 714 on the surface of the card 71 can also be a convex mark, which has the same function as the recessed mark 714, only the form is different.

[0060] In order to avoid the card 71 from being locked or unlocked due to the sliding movement, the card 71 is provided with a tooth groove 713 on the side close to the elastic bullet 72, and the elastic bullet 72 comprises a base 722, a spring 723 and a bullet head 721, which are sequentially arranged in the blind hole 111, wherein the bullet head 721 is in contact with the tooth groove 713 under the elastic force of the spring 723.

[0061] The number of the blind holes 111 is consistent with the number of the elastic bullets 72.

[0062] When a single elastic bullet 72 is arranged, the damping of the card 71 is small, when two elastic bullets 72 are arranged, the damping of the card 71 is increased, and when more elastic bullets 72 are arranged, the damping of the card 71 is sequentially increased. In the selection process, the appropriate number of elastic bullets 72 is selected according to the actual demand, and generally, the damping effect is best when two elastic bullets 72 are arranged.

[0063] As shown in Figure 2 The opposite side surfaces of the main fixed support plate 1 and the auxiliary fixed support plate 2 are provided with an arc, and a cavity for accommodating fingers is formed on the inner side of the main fixed support plate 1 and the inner side of the auxiliary fixed support plate 2, respectively.

[0064] The advantage of this arrangement is that during the installation or disassembly process, the raised cavity facilitates the entry of the fingers of the construction personnel, assists in the fixing of the positions of the main fixed support plate 1 and the auxiliary fixed support plate 2, facilitates the disassembly and installation work of the construction personnel, and can reduce the falling of the main fixed support plate 1 and the auxiliary fixed support plate 2 during the installation process.

[0065] As shown in Figures 1-6 A construction method of a reusable life rope fixing ring structure, comprising the following steps:

[0066] S1, before the formwork of the concrete structure 9, a hole matching the sleeve 8 is reserved at the corresponding position of the formwork of the concrete structure 9

[0067] This step can be completed during the formwork processing. After the installation position of the life rope fixing ring structure and the specific structure (single U-shaped anchor ring 3, double U-shaped anchor ring 3) of the life rope fixing ring structure are determined in the construction drawing of the formwork, the hole opening operation is completed according to the position of the hole.

[0068] S2, after the formwork, the sleeve 8 is placed in the hole, and the post-cast concrete is poured after plugging to obtain the concrete structure 9.

[0069] In step S2, the processing of the sleeve 8 includes two ways:

[0070] 1、According to the thickness of the template, the corresponding thickness of the plugging head (on the one hand to avoid the concrete into the sleeve 8 inside the role, on the other hand to avoid the concrete from the hole in the plate casted from the hole), the sleeve 8 is inserted into the hole in the template, at this time the hole and the sleeve 8 are in a closed state, the plugging head is clamped in the template, realizing the positioning of the sleeve 8, at this time the need for binding and positioning steps in the prior art is eliminated, greatly improving the efficiency of construction.

[0071] 2、The length of the sleeve 8 is set to the thickness of the two templates plus the thickness of the concrete structure 9, at this time without plugging head, the sleeve 8 is inserted into the hole in the template, at this time the hole is closed by the sleeve 8, avoiding the concrete from the hole in the plate casted from the hole, on the other hand, since the two ends of the sleeve 8 are flush with the outside of the template, at this time the concrete in the template will not enter the inside of the sleeve 8, the two ends of the sleeve 8 are clamped in the template, realizing the positioning of the sleeve 8 through the hole, at this time the need for binding and positioning steps in the prior art is eliminated, greatly improving the efficiency of construction, when installing the life rope fixing ring structure after pouring, the excess sleeve 8 can be cut or not.

[0072] S3, after removing the template, the sleeve 8 is left in the concrete structure 9.

[0073] The sleeve 8 can also be removed after the formwork, and the hole formed by the sleeve 8 is directly used for the installation of the life rope fixing ring structure.

[0074] S4, respectively, the main fixed support plate 1 and the auxiliary fixed support plate 2 are placed on the front face 91 and the back face 92 of the concrete structure 9, inserted into the U-shaped anchor ring 3 and locked with the nut 4 for fixation, and the threaded ring 6 is connected.

[0075] S5, after rotating the screw rod 62 part of the threaded ring 6 to completely immerse into the threaded end 5, the card 71 is pushed to lock the position of the threaded ring 6.

[0076] The locking principle is as follows: after pushing the card 71 and placing it in the locked state, since the through hole b712 on the card 71 is in the form of a straight line, it is clamped with the card slot 621 on the screw rod 62, which limits the axial direction of the screw rod 62, at this time the rotating buckle 61 is rotated, the axial movement of the screw rod 62 is limited, which avoids the safety accident caused by the rotation of the threaded ring 6.

[0077] The application adopts the detachable structure, directly inserts the sleeve 8 into the hole of the formwork after reserving the hole on the formwork in the pouring construction process, and pours without binding and positioning, which guarantees the construction efficiency, and before the building curtain wall construction process, the life rope fixing ring structure is installed by using the sleeve 8 to connect the life rope, after use, the life rope fixing ring structure is disassembled to be transported and reused, which can avoid material waste.

[0078] Obviously, various modifications and changes can be made to the present application by those skilled in the art without departing from the spirit and scope of the application. Accordingly, it is intended that all such modifications and changes be included within the scope of the application as defined in the following claims and their equivalents.
