Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a quick-installation device for vertical opening guardrails that does not require drilling. Background Technology

[0002] During construction, protecting openings is a crucial aspect of ensuring safe production. These openings include reserved openings, passageways, elevator shafts, stairwells, and post-cast slab surfaces. Their existence creates potential safety risks such as falls and falling objects during construction. Therefore, effectively protecting all types of openings is an important measure to prevent accidents and ensure the safety of construction workers.

[0003] Traditional methods for installing guardrails at vertical openings typically involve drilling expansion bolts into the wall to secure the guardrails or safety netting. While this method ensures the stability of the guardrails to a certain extent, it also has several problems and shortcomings. First, drilling expansion bolts is labor-intensive and time-consuming, requiring construction workers to use specialized tools for precise operation, increasing the difficulty and cost of construction. Second, the use of expansion bolts can cause some damage to the wall, affecting its aesthetics and integrity. When removing the guardrails, the bolt heads are often left in the wall, which not only affects the wall's appearance but may also cause inconvenience for subsequent decoration and use. To remove these bolt heads, construction workers often need to perform secondary repairs, further increasing construction time and costs. Therefore, we propose a drill-free, quick-installation device for vertical opening guardrails. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example:

[0025] Please see Figures 1-4 A quick-installation device for vertical opening guardrails without drilling is disclosed, comprising two oppositely arranged first U-shaped clips 1, which are used to clamp onto the wall of the vertical opening. A guardrail 2 is provided between the two first U-shaped clips 1, and the guardrail 2 is a telescopic structure. A second U-shaped clip 3 is provided on the side of the first U-shaped clips 1, and the two ends of the guardrail 2 are installed in the second U-shaped clip 3. The first U-shaped clips 1 and the second U-shaped clip 3 are both made of thick steel plates and are welded together.

[0026] A screw rod 4 is threaded through both sides of the first U-shaped clip 1, and the screw rod 4 is threadedly connected to the first U-shaped clip 1. A pad 5 is rotatably connected to the inner end of the screw rod 4. By placing the first U-shaped clip 1 on both sides of the wall and rotating the screw rod 4 to push the pad 5 to one side of the wall, the wall is clamped and fixed to the inner side of the first U-shaped clip 1. The size of the first U-shaped clip 1 is not limited to the figure shown and can be designed according to needs.

[0027] In this application, the pad 5 is made of rubber, which increases the friction when in contact with the wall and will not damage the wall. The inner side of the pad 5 is provided with anti-slip ridges that extend horizontally, which further increases the stability of the pad 5 when in contact with the wall.

[0028] In this application, the guardrail 2 includes a first connecting section 201 and a second connecting section 202. Both the first connecting section 201 and the second connecting section 202 have multiple through holes along their length. By using bolts and nuts, the bolts pass through the through holes on the first connecting section 201 and the second connecting section 202 in sequence to connect and fix the first connecting section 201 and the second connecting section 202. Furthermore, by moving the first connecting section 201 and the second connecting section 202 relative to each other, the overall length of the guardrail 2 can be adjusted according to the width of the opening.

[0029] In this application, a groove is formed on the top surface of the first connecting segment 201, and the second connecting segment 202 slides in conjunction with the groove. The groove restricts the position of the second connecting segment 202, facilitating the sliding extension or shortening of the first connecting segment 201 and the second connecting segment 202. A protrusion is formed on the inner side of the groove at the top surface of the second connecting segment 202, extending along the length of the first connecting segment 201. This protrusion restricts the position of the second connecting segment 202, preventing the first connecting segment 201 and the second connecting segment 202 from misaligning when adjusting their lengths.

[0030] In one possible embodiment, a positioning block 6 is provided at the right angle of the top surface of the first U-shaped card 1, and an mounting component 7 is provided at the right angle of the bottom surface of the first U-shaped card 1. The positioning blocks 6 on two adjacent first U-shaped cards 1 are inserted and engaged with the mounting components 7. The positioning blocks 6 and mounting components 7 facilitate the vertical installation of multiple sets of first U-shaped cards 1 and guardrails 2. First, multiple first U-shaped cards 1 are spliced ​​together, and then connected to the mounting components 7 through the positioning blocks 6. This facilitates the uniform adjustment of the length of the guardrails 2 when installing in vertical openings. When the opening is curved or bent, the first U-shaped cards 1 and guardrails 2 can also be installed independently, thus improving the applicability of the device.

[0031] In this application, the bottom surface of the mounting component 7 is provided with a plug groove 701. The cross-section of the plug groove 701 is T-shaped. On the one hand, the plug groove 701 is designed to facilitate cooperation with the positioning block 6 to splice two adjacent first U-shaped clips 1. On the other hand, the plug groove 701 can also be used to install a protective net. By setting a plug at the end of the protective net that can engage with the plug groove 701, the end of the protective net is fixed at the plug groove 701. By combining two sets of first U-shaped clips 1 and the guardrail 2, the four corners of a protective net can be fixed.

[0032] In this application, two limiting blocks 8 are provided on the top surface of the positioning block 6 near the end. One end of the limiting block 8 is rotatably connected to the positioning block 6. The outer end of the limiting block 8 is set as an arc. By setting the limiting block 8, when the positioning block 6 is inserted into the insertion groove 701, by rotating the limiting block 8, the end of the limiting block 8 is rotated to the stepped groove inside the insertion groove 701, so that the limiting block 8 is stuck in the insertion groove 701, preventing the positioning block 6 from moving in the vertical direction.

[0033] In this application, both the positioning block 6 and the mounting component 7 are L-shaped structures, which facilitates the restriction of position when two adjacent first U-shaped cards 1 are spliced ​​together.

[0034] In use, the two oppositely arranged first U-shaped clips 1 are clamped onto the walls on both sides of the vertical opening. By rotating the screw 4, since the screw 4 is threadedly engaged with the first U-shaped clip 1, the pad 5 is rotatably connected to the screw 4. When the screw 4 is rotated, it pushes the pad 5 to one side of the wall, thereby clamping and fixing the wall to the inside of the first U-shaped clip 1. When fixing the two first U-shaped clips 1, the first connecting section 201 and the second connecting section 202 move relative to each other, lengthening or shortening according to the width of the opening. The groove facilitates the sliding of the first connecting section 201 and the second connecting section 202 relative to each other. The inner side of the groove is provided with a protrusion at the top surface of the second connecting section 202 to restrict the position of the second connecting section 202 and prevent the first connecting section 201 and the second connecting section 202 from being misaligned when adjusting their lengths.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
