Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a pre-embedded positioning device for bolt holes of a climbing frame support. Background Art

[0002] Climbing frames are widely used in the protection of high-rise buildings. The climbing frames need to be attached to the outside of the main structure using wall-mounted supports and need to be lifted using their own equipment, so there are high requirements for the buried position of the wall-mounted supports.

[0003] The traditional climbing frame wall support adopts the method of pre-embedded sleeves without penetrating the formwork. After the structural wall and beam reinforcement is completed, the nylon sleeve is tied and fixed to the steel bar with binding wire, and then the subsequent formwork construction is carried out. After the concrete is poured, the formwork is removed to install the wall support.

[0004] However, when this method is used for construction, each layer of the structure needs to be repositioned, resulting in a slow construction speed. In addition, the casing is not firmly fixed, resulting in the need for re-drilling after deviation, and the casing cannot be reused, which needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a pre-embedded positioning device for the bolt holes of the climbing frame support, which can make the bolt holes of the climbing frame support formed in one time, eliminate the problem of re-drilling due to inaccurate positioning in the later stage, realize the turnover of materials, and improve the construction efficiency and quality.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a pre-embedded positioning device for bolt holes of a climbing frame support, comprising:

[0007] Nylon sleeves are set in the formwork and used to form bolt holes after casting;

[0008] A gasket is arranged on the outside of the template and aligned with the nylon sleeve;

[0009] A fixing bolt is threadedly connected to the nylon sleeve and penetrates the washer.

[0010] In a preferred example, the utility model can be further configured as follows: the outer diameter of the nylon sleeve is gradually reduced from one end close to the fixing bolt to the other end.

[0011] In a preferred example, the utility model can be further configured as follows: the nylon sleeve includes a multi-section tube body, one end of the tube body is provided with a screw rod, and the other end is provided with a screw hole for the screw rod to be screwed into.

[0012] In a preferred example, the utility model can be further configured as follows: a hexagonal groove is provided at one end of the tube body close to the screw hole.

[0013] In a preferred example, the utility model can be further configured as follows: the outer side wall of the nylon sleeve is evenly provided with a plurality of slots arranged along its axial direction, and a clip strip is embedded in the slot, and the outer side wall of the clip strip is flush with the outer side wall of the nylon sleeve.

[0014] In a preferred example, the utility model can be further configured as follows: a concave hole is provided at the end of the clamping strip, and a pull ring is provided in the concave hole.

[0015] In a preferred example, the utility model can be further configured as follows: a steel frame is provided inside the nylon sleeve and the clamping strip.

[0016] In summary, the utility model has the following beneficial effects:

[0017] 1. Before pouring concrete, the washers and fixing bolts are passed through the formwork and fixed to the nylon sleeve. The connection is firm and there is no disturbance of the embedded parts by concrete vibration, which avoids the process of re-drilling in the later stage and saves labor costs. After the concrete pouring is completed, the embedded parts are removed with an electric wrench and can be installed in the same position of the next layer, which realizes multiple turnover and reduces material costs;

[0018] 2. By setting up segmented nylon sleeves, the length and thickness of the nylon sleeves can be switched according to actual use requirements, thereby improving the practicality of embedded parts;

[0019] 3. By setting up a split nylon sleeve, the card strip and the nylon sleeve can be removed in sequence, making the removal and removal process of the nylon sleeve more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Embodiment 1:

[0027] like Figure 1 , Figure 2 As shown, a pre-embedded positioning device for the bolt hole of a climbing frame support includes a nylon sleeve 1, a washer 2 and a fixing bolt 3.

[0028] like Figure 1 , Figure 2 As shown, the nylon sleeve 1 is arranged in the template and is used to form the bolt hole after casting. The outer diameter of the nylon sleeve 1 from one end close to the fixing bolt 3 to the other end is gradually reduced to facilitate the disassembly of the nylon sleeve 1 after use.

[0029] like Figure 1 , Figure 2 As shown, the washer 2 is arranged on the outside of the template and is aligned with the nylon sleeve 1. The fixing bolt 3 is threadedly connected to the nylon sleeve 1 and the washer 2 is passed through.

[0030] Before pouring concrete for structural walls and beams, holes are opened at the designed positions on the template according to the climbing frame detailed drawing, and then the nylon sleeve 1 is placed in the template, with the thick end aligned with the hole on the template, and then the nylon sleeve 1 is fixed to the inside of the template using washers 2 and fixing bolts 3. After pouring concrete for structural walls and beams, the fixing bolts 3, washers 2 and templates are removed in turn, and finally the nylon sleeve 1 is withdrawn from the concrete using an electric wrench to form a bolt embedded hole.

[0031] Therefore, by setting the nylon sleeve 1 fixed at both ends, the nylon sleeve 1 is firmly connected, there is no disturbance of the embedded parts by concrete vibration, and the later re-drilling process is avoided, saving labor costs. At the same time, it can be installed to the same position of the next layer, realizing multiple turnover and reducing material costs.

[0032] Embodiment 2:

[0033] like Figure 3 As shown, the nylon sleeve 1 includes a multi-section tube body 11, a screw rod 12 is arranged at the thin end of the tube body 11, and a screw hole 13 for the screw rod 12 to be screwed into is arranged at the thick end. A hexagonal groove 14 is arranged at one end of the tube body 11 close to the screw hole 13.

[0034] By providing a segmented nylon sleeve 1, the length and thickness of the nylon sleeve 1 can be switched according to actual use requirements, thereby improving the practicality of the embedded part. At the same time, when removing the nylon sleeve 1, a wrench can be inserted into the groove 14 to control the rotation of each section of the tube body 11, thereby realizing the individual removal and quick removal of each section of the tube body 11.

[0035] Embodiment 3:

[0036] like Figure 4As shown, the outer wall of the nylon sleeve 1 is evenly provided with a plurality of slots 15 arranged along the axial direction thereof, and a clip strip 16 is embedded in the slot 15, and the outer wall of the clip strip 16 is flush with the outer wall of the nylon sleeve 1. A concave hole 17 is provided at the end of the clip strip 16, and a pull ring 18 is provided in the concave hole 17.

[0037] When the nylon sleeve 1 needs to be installed, the clamping strip 16 is embedded in the clamping groove 15 so that the two ends of the clamping strip 16 are flush with the two ends of the nylon sleeve 1. When removing the nylon sleeve 1, a tool can be used to hook the pull ring 18, and then the clamping strip 16 can be pulled outward to fall off first, so as to remove the clamping strip 16, and then the electric wrench can be used to control the rotation of the nylon sleeve 1 to remove the nylon sleeve 1. The staged removal method can ensure that the contact area between each part and the concrete is small, and the nylon sleeve 1 and the clamping strip 16 can be easily removed, so as to realize the convenient removal of the nylon sleeve 1.

[0038] like Figure 4 As shown, a steel frame 19 is provided inside the nylon sleeve 1 and the clamping strip 16 to increase the structural strength of the nylon sleeve 1 and the clamping strip 16 to prevent breakage or deformation during the removal process, thereby ensuring convenient removal and stable turnover of the nylon sleeve 1 and the clamping strip 16.
