Abstract
Description
Technical Field
[0001] This utility model relates to the field of building road technology, specifically to a kind of isolation frame for building roads and bridges. Background Technology
[0002] During road and bridge construction, guardrails can delineate construction and non-construction areas, ensuring that the normal passage of vehicles and pedestrians is not affected. This helps maintain smooth traffic flow and reduces traffic congestion and chaos caused by construction. In bridge construction, guardrails can prevent workers or other personnel from accidentally entering the construction area and avoid potential dangers.
[0003] Existing isolation frames for buildings, roads, and bridges are mostly one-time fixed structures. Due to design height limitations, they cannot effectively isolate roadside buildings or obstacles, resulting in substandard isolation effects and insufficient flexibility. Therefore, we propose an isolation frame for buildings, roads, and bridges. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a barrier frame for building roads and bridges, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a barrier frame for building roads and bridges, comprising two crossbeams. Two adjusting outer rods are fixedly installed at the top of one of the crossbeams. Adjusting screws are threaded onto the outer sides of both outer rods. Adjusting inner rods are slidably connected to the inner sides of both outer rods. Several screw holes are formed inside each of the two inner rods, and these screw holes are threaded onto the adjusting screws. The tops of the two inner rods are fixedly connected to the bottom of the other crossbeam. An inner groove is formed inside one of the crossbeams, and two support arms are rotatably connected inside the groove. A sliding rod is fixedly connected between the two outer rods, and two sliders are slidably connected to the outer sides of the sliding rod. Slots are formed inside each of the sliders. The other ends of the two support arms are rotatably connected to the two slots. When the height of the device needs to be increased, one crossbeam is simply pushed upwards using the support arms, and then the adjusting screws and corresponding screw holes are engaged. This process allows the device to be adjusted in height according to requirements, thereby achieving the isolation effect.
[0006] Preferably, each of the two crossbeams has a female head fixedly installed at one end, and each of the two female heads has a pin slidably connected inside. Each of the two crossbeams has a male head fixedly installed at the other end, and each of the two male heads has a hole inside. The pin is slidably connected to the hole. By setting the female and male heads, several devices can be connected using the pin and the hole, thereby increasing the flexibility of the device.
[0007] Preferably, two sliding plates are fixedly installed on one side of one of the crossbeams, and two anti-reverse plates are fixedly installed on one side of the other crossbeam. An installation frame is slidably connected inside the two sliding plates and the two anti-reverse plates, and a guardrail is fixedly installed inside the installation frame.
[0008] Preferably, the mounting frame has two slots inside, and two locking posts are rotatably connected to the top of one of the crossbeams, with the locking posts cooperating with the slots.
[0009] Preferably, a warning sign is fixedly installed on one side of the mounting frame.
[0010] Preferably, two bases are fixedly installed at the bottom end of one of the crossbeams, and each of the two bases has four mounting holes inside.
[0011] This utility model provides a safety frame for building roads and bridges, which has the following beneficial effects:
[0012] 1. The isolation frame for road and bridge construction uses an adjustable outer rod and an adjustable inner rod. First, two sliders are brought closer together, and then two support arms are used to support one of the crossbeams. By using adjusting screws and designated screw holes, the length of the adjusting inner rod extending from the inside of the adjusting outer rod can be changed. Through this process, not only is the height of the device changed, but also an isolation effect is achieved to a certain extent.
[0013] 2. The isolation frame for roads and bridges, through the setting of male and female ends, allows for the assembly of the device when using the isolation frame on an entire road. The male and female ends work together, and then the pins and holes are used to connect them. The device can also be adjusted according to the angle of the road during assembly. This process increases the flexibility of the device. Attached Figure Description

[0020] 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.
[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a partition frame for building roads and bridges, including two crossbeams 1. Two adjusting outer rods 2 are fixedly installed at the top of one of the crossbeams 1. Adjusting screws 201 are threadedly connected to the outer sides of the two adjusting outer rods 2. Adjusting inner rods 3 are slidably connected inside the two adjusting outer rods 2. The adjusting outer rods 2 and adjusting inner rods 3 are used to adjust the height of the device. Several screw holes 301 are opened inside the two adjusting inner rods 3. The screw holes 301 and adjusting screws 201 are threadedly connected. The screw holes 301 and adjusting screws 201 are used to fix the distance between the adjusting inner rods 3 and the adjusting outer rods 2. The top of the two adjusting inner rods 3 is fixedly connected to the bottom of the other crossbeam 1. An inner groove 101 is opened inside the crossbeam 1. Two support arms 5 are rotatably connected inside the inner groove 101. The support arms 5 are used to support one of the crossbeams 1. A sliding rod 6 is fixedly connected between the two adjusting outer rods 2. Two sliders 4 are slidably connected to the outer side of the sliding rod 6. The two sliders 4 are slotted inside the two sliders 4. The other ends of the two support arms 5 are rotatably connected to the two slots 401 respectively.
[0022] like Figure 2 As shown, each of the two crossbeams 1 has a female head 7 fixedly installed at one end, and a pin 701 is slidably connected inside each of the two female heads 7. Each of the two crossbeams 1 has a male head 8 fixedly installed at the other end. The female head 7 and the male head 8 are used to connect the two devices. Each of the two male heads 8 has a socket 801 inside, and the pin 701 is slidably connected to the socket 801. The pin 701 and the socket 801 are used to fix the two devices.
[0023] like Figure 1 As shown, two sliding plates 13 are fixedly installed on one side of one crossbeam 1, and two anti-reverse plates 14 are fixedly installed on one side of the other crossbeam 1. The two sliding plates 13 and the two anti-reverse plates 14 are slidably connected to the mounting frame 9. The mounting frame 9 is fixedly installed with a guardrail 10 for protection.
[0024] like Figure 5 As shown, the mounting frame 9 has two slots 901 inside. Two locking posts 12 are rotatably connected to the top of one of the crossbeams 1. The locking posts 12 cooperate with the slots 901. The locking posts 12 and the slots 901 are used to prevent the mounting frame 9 from shaking randomly.
[0025] like Figure 1 As shown, a warning sign 11 is fixedly installed on one side of the mounting frame 9. The warning sign 11 is used to warn pedestrians and has traffic warning slogans on it.
[0026] like Figure 4 As shown, two bases 15 are fixedly installed at the bottom of one of the crossbeams 1. The bases 15 are used to support the device. Each of the two bases 15 has four mounting holes 151 inside. The mounting holes 151 are used to fix the device on the road.
[0027] In summary, when using this isolation frame for construction roads and bridges, first move the device onto the construction road or bridge, and then place it according to the prescribed method. Because the isolation height varies on each road, it needs to be adjusted to the required height. First, carry the corresponding mounting frame 9 according to the adjusted height, and then the height can be adjusted. First, unscrew the two adjusting screws 201, then bring the two sliders 4 closer together on the sliding rod 6. Then, the two support arms 5 will push the top crossbeam 1 upwards, which will raise the two inner adjusting rods 3 from within the two outer adjusting rods 2. When the required isolation effect is achieved, use the two adjusting screws 201 to engage with the corresponding screw holes 301, thereby... The inner adjusting rod 3 is fixed inside the outer adjusting rod 2. Then, the mounting frame 9 is inserted into the slide plate 13 and the anti-reverse plate 14 in sequence to complete the assembly. Since a warning sign 11 is installed on one side of the mounting frame 9, the road isolation sign 11 can be written on the warning sign 11 to warn pedestrians. When it is necessary to splice the device, insert the male head 8 into the female head 7, insert the pin 701 into the insertion hole 801, and rotate the device according to the angle of the road to match the isolation effect of the road. After the device is fully installed, in order to ensure the stability of the device, the mounting screws and mounting holes 151 are used to fix the device on the road. The above is the working principle of this utility model.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
