Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering protective frames, and particularly relates to an adjustable protective frame for temporary construction in construction engineering. Background Technique

[0002] In the current construction engineering field, especially for the safety protection of high-risk areas such as elevator shafts and unclosed windows during high-rise building construction, traditional methods mostly use building steel pipes combined with wire winding to build temporary protective frames. However, this method not only has low efficiency and a cumbersome construction process, but also the formed protective net has large gaps and limited protective performance, making it difficult to effectively prevent accidents. In addition, due to the significant differences in the layout and spacing dimensions of different construction sites and specific operation areas, traditional protective frames lack flexibility and are difficult to adapt to diverse needs, further reducing the efficiency of erection and disassembly, and increasing construction time and labor costs.

[0003] To solve the above problems, some construction units have adopted the solution of customizing protective frames. However, since the design schemes of each construction project are different, these customized protective frames are often difficult to be reused in other projects after demolition, resulting in a large amount of idle and wasted resources and high costs. Therefore, there is a certain market demand for designing a protective frame that has both high efficiency in erection and disassembly. Summary of the Invention

[0004] In view of the above deficiencies of the prior art, the utility model provides an adjustable protective frame for temporary construction in construction engineering to solve the above problems.

[0005] An adjustable protective frame for temporary construction in construction engineering of the utility model includes a first side rod and a second side rod. A telescopic grille is hinged between the first side rod and the second side rod. Locking parts are arranged at the hinge points of the first side rod and the telescopic grille, and the hinge points of the second side rod and the telescopic grille. A plurality of left insertion plates extending leftward are arranged on the front surface of the first side rod, and a plurality of right insertion plates extending rightward are arranged on the front surface of the second side rod. Left slots corresponding to the right insertion plates one by one are arranged on the front surface of the first side rod, and right slots corresponding to the left insertion plates one by one are arranged on the front surface of the second side rod.

[0006] Further, rubber strips are arranged at the left end of the first side rod and the right end of the second side rod, and anti-slip patterns are arranged on the rubber strips.

[0007] Further, both the first side rod and the second side rod are hollow square tubes, and socket joints are arranged at the tops.

[0008] Further, rubber pads are arranged on the socket joints.

[0009] Further, through holes are provided on the plug connector, and fixing jacks corresponding to the through holes are provided on one side of the bottom ends of the first side rod and the second side rod.

[0010] Further, handles are provided on the front and rear sides of the top ends of the first side rod and the second side rod.

[0011] Further, the locking part is a fastening knob.

[0012] Compared with the prior art, the protective frame effectively solves the problems of low construction efficiency, poor protection performance and weak adaptability of the traditional protective frame. Through the retractable grille and plug-in slot design, flexible adjustment and quick connection are realized, the protection performance and stability are enhanced, and it is easy to disassemble, install and reuse, reducing the construction cost and improving the construction safety and efficiency.

[0019] In order to better understand the present invention, the following will be combined with Figures 1 to 5 to explain in detail the embodiments of the present invention.

[0020] It should be noted that the "front, rear, left, right, up, down" directions described in the text are all based on the Figure 1 "front, rear, left, right, up, down" directions in.

[0021] See Figures 1 to 5The utility model discloses an adjustable protective frame for temporary construction of a building project, comprising a first side bar 1 and a second side bar 2. A retractable telescopic grille 3 is hinged between the first side bar 1 and the second side bar 2. The first side bar 1 and the second side bar 2 serve as the main frame of the protective frame. The design adopts a hollow square tube material. This design not only reduces the overall weight, facilitates transportation and installation, but also enhances the stability and durability of the structure. The hinge point between the first side bar 1 and the telescopic grille 3 and the hinge point between the second side bar 2 and the telescopic grille 3 are both provided with a locking portion 4. By adjusting the telescopic grille 3, the user is allowed to adjust the distance between the first side bar 1 and the second side bar 2 according to actual needs to adapt to protection areas of different sizes. Figure 5 As shown in , after the telescopic grille 3 is expanded, the left end of the first side rod 1 and the right end of the second side rod 2 are respectively against the walls on both sides. At this time, the locking part 4 is used to lock the telescopic grille 3 to form protection.

[0022] like Figure 1 and Figure 4 As shown in , the locking portion 4 is preferably a tightening knob (existing technology), which can tighten or loosen the telescopic grille 3 by rotating it to ensure that it can be firmly locked after being adjusted to a suitable position to prevent accidental movement.

[0023] Considering the rough surface of the wall, in order to increase the friction between the protective frame and the wall surface and improve the firmness, such as Figure 3 As shown in the figure, the left end of the first side rod 1 and the right end of the second side rod 2 are both provided with rubber strips 9, and the rubber strips 9 are provided with anti-slip patterns. The contact area with the wall surface is increased by the setting of the rubber strips 9 and the anti-slip patterns to enhance the stability of the protective frame after installation.

[0024] Considering that some project sites have oversized windows, the maximum length of a single protective frame after being stretched out is not enough to support the distance of the oversized window. Therefore, the protective frame is also designed with a structure that can connect multiple protective frames horizontally to achieve extension. Figure 1 , Figure 2 and Figure 3As shown in the figure, on the front of the first side rod 1, there are several left insertion plates 5 extending leftward, and correspondingly, on the second side rod 2, there are several right insertion plates 6 extending rightward. On the front of the first side rod 1, there are left slots 7 corresponding one-to-one to the right insertion plates 6, and on the front of the second side rod 2, there are right slots 8 corresponding one-to-one to the left insertion plates 5. By docking the second side rod 2 of one protective frame with the first side rod 1 of another protective frame, multiple protective frames can be horizontally docked to achieve an extended structure. The above-mentioned left insertion plates 5 and right insertion plates 6 are only used for the quick connection of multiple protective frames in the horizontal direction and also have a baffle function. When the anti-slip rubber strips 9 (set at both ends and with anti-slip patterns) on the first side rod 1 and the second side rod 2 are closely abutted against the wall, the left insertion plates 5 and the right insertion plates 6 will respectively form an L-angle structure with the walls on both sides. This design effectively prevents the protective frame from tipping or falling outward due to external forces, enhancing the overall stability and safety of the protective frame.

[0025] In addition, for construction environments with different floor heights, especially in areas such as elevator shafts near stairs where higher requirements are placed on the protection height, the protective frame provides a flexible solution. Since after the telescopic grille 3 is fully opened, its width will increase while its height will correspondingly decrease, which may result in insufficient protection height. For this reason, at the top ends of the first side rod 1 and the second side rod 2, there are insertion joints 10, which are adapted to the ports of the hollow square tubes, enabling the protective frame to achieve the up-and-down docking of two or more protective frames through the up-and-down plugging of the insertion joints 10. In addition, the insertion joints 10 are designed with rubber pads 11 to increase friction, and are provided with through holes 12, and on one side of the bottom ends of the first side rod 1 and the second side rod 2, there are fixed jacks 13 corresponding to the through holes 12. After the two protective frames are docked up and down, bolts and other fasteners are allowed to be used for further fixation. In this way, the height of the protective frame can be adjusted according to actual needs to meet the requirements of different construction scenarios.

[0026] To improve the safety and convenience during operation, handles 14 are also provided on the front and rear sides of the top end of the protective frame, facilitating two construction workers to open or contract the telescopic grille 3 from both sides.
