[0001] This utility model relates to the field of building engineering safety technology, and in particular to a warning device for building construction. Background Technology

[0002] The background technology of construction safety railings originated from the need to prevent safety risks such as falls from heights and falling objects during construction. In the early days, simple bamboo, wood or steel pipes were used to build them. With the development of technology, a protective system based on mechanical calculations, standardized materials such as Q235 steel pipes and aluminum alloys and modular design has gradually been formed. At the same time, innovative technologies such as intelligent monitoring have been incorporated to improve safety.

[0003] In existing technologies, traditional integrated guardrails have a fixed overall structure. When there is a large demand for them, the overall handling is labor-intensive and they are easily damaged. They are inconvenient to carry and transport, and are easily damaged by collisions during transport. In addition, traditional railings or nets are pre-made and cannot adapt to changes in on-site needs. The protective components are fixed and cannot be flexibly replaced or adjusted later.

[0004] Therefore, a warning device for construction engineering is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a warning device for construction engineering, which can solve the problems of existing integrated guardrails being inconvenient to carry, difficult to transport, and easily damaged during storage, as well as the problem that the protective components of traditional guardrails are fixed and cannot be flexibly replaced or adjusted.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a warning device for construction engineering, comprising two crossbeams, with a quick pre-assembly mechanism movably connected to both sides of the two crossbeams, a main rod movably connected to the outer side of the quick pre-assembly mechanism, and a fence assembly movably connected to one side of each of the two crossbeams, with a net movably connected to the inner side of the fence assembly and a railing movably connected to the inner side of the fence assembly. The quick pre-assembly mechanism includes a limiting box fixedly connected to both sides of the crossbeam. An elastic mounting component is movably connected to the inner side of the limiting box. Two snap-fit ​​sliders are movably connected to the outer side of the elastic mounting component. The two snap-fit ​​sliders are located at the top and bottom of the outer side of the limiting box. An installation groove is provided on the outer side of the main rod. The top and bottom of the installation groove are provided with slots.

[0007] Preferably, the enclosure assembly includes two limiting sliding boxes fixedly connected to the outside of the crossbeams, and the two limiting sliding boxes are respectively distributed on the corresponding side of the two crossbeams. The limiting sliding boxes are movably connected to the outside of the top and bottom of the netting and railing.

[0008] Preferably, a mounting base plate is fixedly connected to the bottom of the inner side of the bottom limiting slide box, and a positioning slot is provided on the inner side of the mounting base plate. Positioning blocks are fixedly connected to the bottom of the railing and the net, and the positioning blocks are inserted into the inner side of the positioning slot.

[0009] Preferably, an array of telescopic rods is fixedly connected to the top of the inner side of the top limiting slide box, a compression spring is fixedly connected to the inner side of the array of telescopic rods, a contact plate is fixedly connected to the bottom of the compression spring, and the contact plate is located at the top of the barrier and railing.

[0010] Preferably, the elastic mounting assembly includes two telescopic columns fixedly connected to the inside of the limiting box, and the two telescopic columns are respectively distributed at the top and bottom of the inside of the limiting box, and a tension spring is fixedly connected to the inside of the telescopic columns.

[0011] Preferably, each of the two telescopic columns has a fixed connecting slide plate on one side.

[0013] Preferably, a contact pad is fixedly connected to the bottom of the contact plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application, by setting up a quick pre-assembly mechanism, can disassemble the guardrail into two sets of main poles, two sets of crossbeams, and several prefabricated components of railings and netting. This enables the classified storage and transportation of the required components. Since the components are of equal shape, they can avoid collision damage during transportation. Furthermore, classified storage reduces the overall handling difficulty. During installation, by utilizing the linkage pressure rod, linkage slide plate, telescopic column, and tension spring in the crossbeam limiting slide box, the limiting clamping assembly of the crossbeam and main pole can be quickly completed through simple pressing and releasing operations. This solves the problems of the traditional integrated guardrail having a fixed overall structure, which is labor-intensive and easily damaged when there is a large demand, and is inconvenient to carry and transport, as well as being easily damaged by collisions during transportation. 2. This application, by setting up a fence assembly, enables flexible installation and adjustment of railings and netting using top and bottom limiting sliding boxes. During installation, the contact plate inside the top limiting sliding box is manually pushed to compress the array telescopic cylinder and compression spring, allowing the bottom positioning block of the netting or railing to slide into the opening. After releasing, it is positioned. During adjustment, the assembly is lifted and the contact plate is pressed, allowing the installation point to be switched or removed by sliding within the sliding box. This method eliminates the need for fixed pairing of railings and netting, allowing for easy replacement and adjustment of the combination and distribution according to site requirements. This solves the problems of traditional protective components being difficult to adapt to changes in site requirements after processing and shaping, and having fixed combinations that cannot be flexibly replaced or adjusted later.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 The present invention provides the following technical solution: A construction warning device includes two horizontal beams 1, with a quick pre-assembly mechanism 2 movably connected to both sides of the two horizontal beams 1, a main rod 3 movably connected to the outer side of the quick pre-assembly mechanism 2, a fence assembly 4 movably connected to one side of each of the two horizontal beams 1, a barrier net 5 movably connected to the inner side of the fence assembly 4, and a railing 6 movably connected to the inner side of the fence assembly 4. The quick pre-assembly mechanism includes a limiting box 21 fixedly connected to both sides of the crossbeam 1. An elastic mounting component 22 is movably connected to the inner side of the limiting box 21. Two snap-fit ​​sliders 23 are movably connected to the outer side of the elastic mounting component 22. The two snap-fit ​​sliders 23 are located at the top and bottom of the outer side of the limiting box 21. An installation groove 24 is provided on the outer side of the main rod 3. A slot 25 is provided at the top and bottom of the installation groove 24.

[0019] In this embodiment: instead of using the traditional integrated guardrail, a prefabricated guardrail section consisting of two sets of main poles 3, two sets of crossbeams 1, several railings 6, and a net 5 is used. When in use, components of the same shape can be classified, stored, and transported to avoid collisions. After arriving at the construction environment, it can be quickly and flexibly assembled: first, the larger surface of one side of the main pole 3 is placed on the ground, and the two sets of crossbeams 1 are taken out and the outer limit sliding box 41 of the crossbeam 1 is oriented towards the center of the main pole 3. Using the limit box 21 and elastic installation component 22 on the installation side of the crossbeam 1 and the main pole 3, the two locking sliders 23 are brought closer to each other, the distance between them is reduced, and the lateral distance is shortened so that they can enter the inner side of the main pole 3 installation groove 24 at the same time. After pushing the crossbeam 1 to the innermost side of the installation groove 24 and stabilizing it horizontally, the linkage pressure rod 7 is released. Under the pull back of the telescopic columns 22a on both sides and the inner tension spring 22b, the two linkage sliding plates 22c drive the locking sliders 23 to slide to both sides, the distance between them increases, and they are locked into the two sets of locking slots 25 in the installation groove 24 to complete the limit locking and achieve quick assembly.

[0020] Specifically, such as Figure 1 , Figure 4 As shown, the enclosure assembly 4 includes two limiting slide boxes 41 fixedly connected to the outside of the crossbeam 1, and the two limiting slide boxes 41 are respectively distributed on the corresponding side of the two crossbeams 1. The limiting slide boxes 41 are movably connected to the outside of the top and bottom of the netting 5 and the railing 6.

[0021] Specifically, such as Figure 1 , Figure 4 As shown, a mounting base plate 42 is fixedly connected to the bottom of the inner side of the bottom limiting slide box 41. A positioning slot 43 is provided on the inner side of the mounting base plate 42. Positioning blocks 44 are fixedly connected to the bottom of the railing 6 and the net 5. The positioning blocks 44 are inserted into the inner side of the positioning slot 43.

[0022] Specifically, such as Figure 1 , Figure 4As shown, an array of telescopic rod cylinders 45 is fixedly connected to the top of the inner side of the top limiting slide box 41, a compression spring 46 is fixedly connected to the inner side of the array of telescopic rod cylinders 45, and a contact plate 47 is fixedly connected to the bottom of the compression spring 46. The contact plate 47 is set at the top of the barrier net 5 and the railing 6.

[0023] In this embodiment: The unobstructed side of the crossbeam 1 facilitates installation in the protected area. The installation process for the railing 6 or the netting 5 is as follows: First, align the side with the positioning block 44 on its outer side with the opening on one side of the bottom limiting slide box 41. Then, manually push the contact plate 47 inside the top limiting slide box 41 upwards a short distance to stably insert the bottom into the aligned opening. Next, push the netting 5 or railing 6 directly in and release the brief pressure on the contact plate 47. This installation method is because the railing 6 and netting 5 have positioning blocks 44 at their bottoms, and the overall travel is greater than the area where the top enters the limiting slide box 41. When the bottom is in contact with the opening of the limiting slide box 41, it can slide in and out; when the top is in contact with the opening... When in the positioning installation state, the contact plate 47 needs to be pressed upward to retract the array telescopic cylinder 45 and the inner compression spring 46 between it and the inner wall of the top limiting slide box 41. This creates a gap between the part of the net 5 and the railing 6 located inside the top limiting slide box 41 and the opening, making it easier for the bottom to be aligned and slide in. During adjustment, lift the net 5 or railing 6 upward inside the limiting slide box 41 to disengage the bottom positioning slot 43 from the positioning insert 44. Then press the contact plate 47, and the net 5 or railing 6 can slide left and right to select the installation point of another positioning slot 43 or remove it, thereby realizing convenient installation of the protected area, flexible adjustment of combination and distribution to meet protection requirements.

[0024] Specifically, such as Figure 2 , Figure 3 As shown, the elastic mounting assembly 22 includes two telescopic columns 22a fixedly connected to the inside of the limiting box 21, and the two telescopic columns 22a are respectively distributed at the top and bottom of the inside of the limiting box 21. A tension spring 22b is fixedly connected to the inside of the telescopic column 22a.

[0025] Specifically, such as Figure 2 , Figure 3 As shown, each of the two telescopic columns 22a has a fixed connecting slide plate 22c on one side. The connecting slide plate 22c is slidably connected to the inside of the limit box 21. Two snap-fit ​​sliders 23 are fixedly connected to the outside of the connecting slide plate 22c and are respectively distributed on the opposite side of the connecting slide plate 22c.

[0026] In this embodiment: by pressing the two sets of linkage pressure rods 7 on one side of the limiting box 21, the linkage pressure rods 7 slide towards the center of the limiting box 21 at the same time, and drive the linkage slide plate 22c inside the limiting box 21 to move towards the center. When the linkage slide plate 22c moves, the telescopic column 22a and its internal tension spring 22b between it and the inner wall of the limiting box 21 will be stretched and accumulate elastic potential energy. The locking sliders 23 on the outer side of the two sets of linkage slide plates 22c approach each other under the pressure and the distance between them decreases. The lateral distance is shortened to the point that they can enter the inner side of the mounting groove 24 of the main rod 3 at the same time. After placing the crossbeam 1 in the innermost side of the mounting groove 24 and stabilizing it in a horizontal state, the linkage pressure rods 7 are released. Under the pull back of the telescopic columns 22a on both sides and the inner tension springs 22b, the two linkage slide plates 22c drive the two locking sliders 23 to slide to both sides and the distance between them increases. They are locked into the two sets of locking slots 25 inside the mounting groove 24, and the limiting and locking are completed.

[0027] Specifically, such as Figure 3 As shown, the front and rear sides of the linkage slide plate 22c are fixedly connected with linkage pressure rods 7, and the linkage pressure rods 7 are slidably connected to the outside of the limit box 21.

[0028] Specifically, such as Figure 4 As shown, a contact pad 8 is fixedly connected to the bottom of the contact plate 47.

[0029] In this embodiment: the linkage pressure rod 7 facilitates the adjustment of the internal linkage slide plate 22c from the outside, and the contact pad 8 can reduce contact damage to personnel, the barrier net 5, and the fence.

[0030] Working Principle: In construction sites, protective fences are typically used to warn of dangerous areas and prevent people from approaching. However, traditional integrated protective fences are inconvenient to carry and transport when large quantities are needed, and can be damaged by collisions during transport. Furthermore, existing protective fences usually select either railings 6 or netting 5, or a combination of both, but these are usually pre-designed and cannot be changed or freely combined according to needs. Therefore, traditional integrated protective fences are no longer used. Instead, a section of prefabricated protective fence consisting of two sets of main poles 3, two sets of crossbeams 1, and several railings 6 and netting 5 is used. During use, the required components can be categorized, stored, and transported in a way that avoids collisions, ensuring the fence reaches the construction site. After the work environment is set up, quick and flexible splicing can be achieved. First, take out one side of the main rod 3 and place its larger side on the ground. Then, take out two sets of crossbeams 1. After ensuring that the limiting sliding box 41 on the outside of the crossbeam 1 faces the center of the main rod 3, use the limiting box 21 on the installation side of the crossbeam 1 on the main rod 3. By pressing the two sets of linkage pressure rods 7 on one side of the limiting box 21, the linkage pressure rods 7 slide towards the center of the limiting box 21 at the same time. This drives the linkage sliding plate 22c inside the limiting box 21 to move towards the center. During the movement of the linkage sliding plate 22c, the telescopic column 22a between it and the inner wall of the limiting box 21 and the tension spring 22b inside it will be manually pressed to stretch and allow the tension spring 22b inside to accumulate elastic potential energy for rebound. The two sets of linkage... The outer side of the sliding plate 22c is equipped with locking sliders 23. Under pressure, the two locking sliders 23 move closer together, reducing their distance. This shortens the lateral distance enough for both locking sliders 23 to simultaneously enter the inner side of the mounting groove 24 of the main rod 3. After being placed at the innermost part of the mounting groove 24, the horizontal state of the crossbeam 1 is stabilized, and the pressure on the linkage rod 7 is released. Under the pull back of the telescopic columns 22a on both sides and the inner tension spring 22b, the two linkage sliding plates 22c quickly slide to both sides, increasing the distance between the two locking sliders 23 and causing them to engage with the two sets of locking slots 25 located inside the mounting groove 24. This completes the limiting and locking, enabling quick assembly. After installing another set of crossbeams 1 in the same way, the protected area can be flexibly configured. Due to the above... Only one set of main poles 3 was installed, so the other side of the crossbeam 1 was unobstructed, facilitating the installation of the protected area. The main installation process for both the railing 6 and the netting 5 is as follows: First, align the side of the railing 6 or netting 5 with the positioning block 44 with the opening on one side of the bottom limiting slide box 41. Then, manually push the contact plate 47 inside the top limiting slide box 41 upwards a short distance so that the bottom aligned opening can be stably entered. This allows the netting 5 or railing 6 to be directly pushed in, while simultaneously releasing the brief pressure on the contact plate 47. This installation method is necessary because the bottom of the railing 6 and netting 5 is equipped with positioning blocks 44 for locking, so the overall travel is greater than the area where the top enters the limiting slide box 41, and the bottom must be in contact with the opening of the limiting slide box 41 before it can slide in and out.When the top of the sliding box 41 is in a positioning installation state, it is necessary to press the contact plate 47 upwards, causing the array telescopic cylinder 45 and its inner compression spring 46 between it and the inner wall of the top sliding box 41 to retract. This creates a certain gap between the inner part of the baffle 5 and the railing 6 of the top sliding box 41 and the opening of the top sliding box 41, thus aligning the bottom and allowing direct sliding. Similarly, during adjustment, simply lift the baffle 5 or railing 6 upwards from the inside of the sliding box 41 to disengage its bottom positioning slot 43 from the positioning insert 44. The aforementioned pressing contact plate 47 allows the guardrail 5 or railing 6 to slide left and right, enabling the selection of installation points for additional positioning slots 43 or their removal. In summary, this allows for convenient installation of the protected area, with flexible adjustments to its combination and distribution to meet protection requirements. After the protected area is installed, the other main pole 3 can be installed as described above, thus installing one section of the guardrail. Although the description is lengthy, the overall installation method is simple, easy to learn, requires no installation experience, and achieves pre-assembly, thus optimizing the construction warning device for building engineering.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
