With continuous technological innovation and market demand growth, this field will usher in a broader development prospect.

[0003] In the prior art, in the practice of building engineering safety protection, such protection structures as tripods provide necessary safety protection to a certain extent, but there are still some significant inconveniences and hidden dangers in their design and use process. When the staff moves in the work area, they often encounter the situation that the activity area is separated by discontinuous protection facilities, which not only affects the work efficiency, but more importantly, increases the safety risk. In order to solve this problem, a transition plate is usually used to connect these intermittent areas to ensure that personnel can pass smoothly and safely, however, the transition plates on the market are often designed to be carried by the staff, which undoubtedly increases their work burden. In the busy and complex construction site, the staff chooses to risk crossing the gap without a transition plate because they forget to carry it or cannot quickly find it, which greatly increases the risk of accidents. In addition, even if the transition plate is carried, the on-site installation also wastes unnecessary time due to the steps of finding a suitable position, adjusting alignment, etc., which further reduces the work efficiency and causes safety hazards. UTILITY MODEL CONTENT

[0004] The utility model aims at solving the shortcomings in the prior art and provides a safety protection structure based on building engineering.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a safety protection structure based on building engineering, comprising a longitudinal beam, a cross beam is fixed on one side of the longitudinal beam, a sandwich beam is fixed on one side of the longitudinal beam, a limiting wing groove is formed on one side of the longitudinal beam, a wing plate is slidably connected to the inner wall of the limiting wing groove, a transition main plate is fixed on one side of the wing plate, the surface of the transition main plate is slidably connected with the inner wall of the sandwich beam, the wing plate and the longitudinal beam are fixed by bolts, an end upper plate is fixed at one end of the transition main plate, and an end lower plate is fixed at the other end of the transition main plate.

In the actual operation environment of the construction site, the transition main plate as a key component for connecting adjacent longitudinal beams bears the important responsibility of personnel passage and equipment transportation. However, the design feature of being suspended below can cause significant safety hazards in certain situations, especially when heavy equipment or machinery needs to pass from the top. Specifically, due to the lack of effective support structure below the transition main plate, when the weight of heavy equipment is applied to its upper surface, this concentrated load can easily cause the transition main plate to bend or deform. Once the transition main plate fails structurally under such heavy pressure, not only will it damage the transition main plate itself, but it will also trigger a chain reaction, such as causing the longitudinal beam connection to fail, the working platform to become unstable, and even causing the equipment to overturn, the personnel to fall, and other serious production accidents, posing a major threat to the safety of the construction site. In addition, the bending of the transition main plate also affects the stability and continuity of the entire protection system, making the protective measures designed to ensure safety useless, increasing the risk of operation and management difficulty. To solve these problems, the utility model adopts the installation of T-shaped pad rails, which realizes that when the workers install the transition main plate, the workers first pull out the T-shaped pad rail from the T-shaped receiving groove. When the adjacent T-shaped pad rails contact, the workers turn one end of the T-shaped pad rail to install, so that the end single fixing ring and the end double fixing ring of the adjacent T-shaped pad rails contact, the end double fixing ring is placed in the slot of the other T-shaped pad rail to improve stability, the workers tighten the bolts and nuts to fix the end single fixing ring and the end double fixing ring, and then the T-shaped pad rail is fixed by the rail screw hole and the beam screw hole, so as to keep the stability of the component and improve the stability of the equipment.

[0012] Beneficial effects:

[0013] 1、In the prior art, in the practice of construction safety protection, although such protection structures as tripods provide necessary safety protection to a certain extent, there are still some significant inconveniences and hidden dangers in the design and use process. When the staff moves in the work area, they often encounter the situation that the active area is separated by discontinuous protection facilities, which not only affects the work efficiency, but more importantly, increases the safety risk. In order to solve this problem, a transition plate is usually used to connect these intermittent areas to ensure that personnel can pass through smoothly and safely. However, the transition plates on the market often need to be carried by the staff, which undoubtedly increases their work burden. In a busy and complex construction site, the staff chooses to risk crossing the gap without a transition plate because they forget to carry it or have difficulty in quickly finding it. This behavior greatly increases the risk of accidents. In addition, even if the transition plate is carried, the on-site installation still wastes unnecessary time due to the steps of finding a suitable position, adjusting alignment, etc., which further reduces work efficiency and causes safety hazards. In view of such problems, the utility model adopts the installation of a transition main plate to solve the problem. When the staff needs to cross the gap between two adjacent longitudinal beams, they only need to simply perform a series of ingenious steps to quickly deploy and stably install the transition main plate. Specifically, the staff first identifies the specific position where the transition main plate needs to be installed, that is, the two longitudinal beams to be connected. Then, they gently pull out the pre-designed transition main plate on the inner side of each longitudinal beam. This ingenious design allows the transition main plate to be hidden inside the longitudinal beam when not in use, keeping the site clean and not affecting the work process. In order to ensure smooth and safe transition, the staff will turn one side of the transition main plate by 180 degrees. In this way, the two adjacent transition main plates can be tightly fitted in the form of an end-on plate and an end-down plate, forming a continuous and stable bridge platform. This corresponding design not only enhances the stability of the structure, but also effectively prevents accidental slipping when personnel or materials pass through. According to the actual construction site requirements, the staff can flexibly adjust the pull-out length of the transition main plate. Whether it is a narrow or wider gap, the most suitable extension distance can be found to ensure that the passing demand is met while avoiding excessive space occupation. Once the optimal position is determined, the end-on plate and the end-down plate are fixed by using screws through the pre-designed screw holes on the surface of the end-on plate and the end-down plate. This step further reinforces the structural stability of the transition main plate. Finally, in order to ensure the long-term stability and durability of the entire device, additional screws are used to firmly connect the wing plates on the transition main plate with the longitudinal beam itself. This design not only keeps the transition main plate stable inside the longitudinal beam at all times, but also greatly simplifies the installation process, reducing the operational difficulty and time cost of the staff, thereby improving work efficiency while ensuring safety, achieving the effect of improving user experience and increasing the application range of the product.

[0014] 2、In the prior art, in the actual operating environment of the construction site, the transition main plate as the key component connecting adjacent longitudinal beams undertakes the important responsibility of personnel access and equipment carrying. However, its design feature of hanging in the air below can cause significant safety hazards in specific situations, especially when heavy equipment or machinery needs to pass from the top thereof. Specifically, due to the lack of effective support structure below the transition main plate, when the weight of heavy equipment is applied to the upper surface thereof, the concentrated load can easily cause the transition main plate to bend or deform. Once the transition main plate fails structurally due to being unable to withstand such heavy pressure, not only the transition main plate itself will be damaged, but also a chain reaction will be caused, such as causing the longitudinal beam connection to fail, the working platform to be unstable, and even causing the equipment to overturn, the personnel to fall, and other serious production accidents, which pose a major threat to the safety of the construction site. In addition, the bending of the transition main plate also affects the stability and continuity of the entire protection system, making the protective measures originally designed to ensure safety become a mere formality, increasing the operation risk and management difficulty. In view of such problems, the utility model adopts the installation of T-shaped pad rails to solve the problem, which realizes that before the installation of the transition main plate, the worker first takes out the T-shaped pad rail from the T-shaped storage slot. When the adjacent T-shaped pad rails contact, the worker turns one end of the T-shaped pad rail to install, so that the end single fixed ring and the end double fixed ring of the adjacent T-shaped pad rails contact, the end double fixed ring is placed in the other T-shaped pad rail to improve the stability, the worker raises the bolt nut to fix the end single fixed ring and the end double fixed ring, then fixes the T-shaped pad rail through the rail screw hole and the beam screw hole, so as to keep the stability of the component, and achieve the effect of improving the stability of the equipment.

[0015] 3、In the prior art, in the safety protection system of construction engineering, steel net plays a crucial role, which not only can effectively prevent personnel or object from falling accidentally, but also can resist the invasion of external environmental factors to a certain extent, guarantee the safety and stability of the construction site, however, although its protection function is remarkable, steel net faces a problem that cannot be ignored in the actual installation process: because the length of the steel net is usually long, which makes its installation process such as carrying, positioning and fixing particularly cumbersome and difficult, specifically, the long size of the steel net is not light in weight, and needs multiple workers to work cooperatively to complete the carrying, which not only increases the labor intensity, but also improves the operation difficulty, in the installation process, it is a test of technology and patience to accurately place the heavy steel net to the predetermined position and ensure that the tension is moderate and fixed firmly, in addition, because the area of the steel net is large, once the installation is not in place or needs to be adjusted, the cost and time consumption of rework will be significantly increased, which undoubtedly further reduces the work efficiency and affects the operation experience of the workers, in view of such problems, the utility model adopts the installation of net edge square to solve the problem, realizes that when the workers install the steel net, the net edge square on both sides of the steel net is respectively placed in the square groove of the longitudinal beam, and the position of the net edge square in the square groove is limited through the combination of the screw fixing groove and the fixed residual circle, and the fixed residual circle and the screw fixing groove are fixed by using the bolt, so that the length and the installation complexity of the steel net are significantly reduced, and the effect of improving the user experience is achieved.

However, despite its significant protective function, the steel mesh 404 faces a problem that cannot be ignored in the actual installation process: because the length of the steel mesh 404 is usually long, it makes the installation process such as carrying, positioning and fixing particularly cumbersome and difficult. Specifically, the long-size steel mesh 404 is often not light in weight, and needs to be carried by multiple workers, which not only increases the labor intensity, but also increases the operation difficulty. In the installation process, it is a test of technology and patience to accurately place the heavy steel mesh 404 in the predetermined position and ensure that it is moderately tensioned and firmly fixed. In addition, due to the large area of the steel mesh 404, once the installation is not in place or needs to be adjusted, the cost and time consumption of rework will increase significantly, which undoubtedly further reduces the work efficiency and affects the operation experience of the workers. The installation of the net edge rectangle 402 solves the problem, which realizes that when the workers install the steel mesh 404, the net edge rectangle 402 on both sides of the steel mesh 404 is placed in the rectangular groove 4 of the longitudinal beam 1 respectively, and the position of the net edge rectangle 402 in the rectangular groove 4 is limited through the combination of the screw fixing groove 401 and the fixed residual circle 403, and the fixed residual circle 403 and the screw fixing groove 401 are fixed by bolts, thereby significantly reducing the length and installation complexity of the steel mesh 404, and achieving the effect of improving the user experience.

The anti-skid groove is provided at the top of the transition main plate 2, which realizes the convenience of the workers, and achieves the effect of improving the user experience.

[0029] The working principle of the utility model discloses: when the staff faces the gap between two adjacent longitudinal beams 1, they only need to simply execute a series of ingenious steps, namely, the quick deployment and stable installation of the transition main plate 2 can be realized, in particular, the staff first identifies the specific position of the transition main plate 2 to be installed, namely, the two longitudinal beams 1 to be connected, then, they gently pull out the transition main plate 2 preset on the inner side of the two longitudinal beams 1, this ingenious design allows the transition main plate 2 to hide in the longitudinal beam 1 when not in use, keeps the site clean and does not affect the operation process, in order to ensure the smoothness and safety of transition, the staff will turn the transition main plate 2 on one side by 180 degrees, in this way, the two adjacent transition main plates 2 can be closely fitted in the form of end upper plate 202 and end lower plate 201, forming a continuous and stable bridge platform, this corresponding design not only enhances the stability of the structure, but also effectively prevents accidental falling when personnel or materials pass, according to the actual construction site requirements, the staff can flexibly adjust the pull-out length of the transition main plate 2, whether it is narrow or wide gap, the most suitable stretching distance can be found, ensuring that the passing demand is met and the space is not occupied too much, once the best position is determined, through the screw hole on the surface of the end upper plate 202 and the end lower plate 201, the structure stability of the transition main plate 2 is further reinforced by using bolts, finally, in order to ensure the long-term stability and durability of the whole device, the wing plate 203 on the transition main plate 2 and the longitudinal beam 1 itself are firmly connected by using additional bolts, this design not only makes the transition main plate 2 always maintain a stable state inside the longitudinal beam 1, but also greatly simplifies the installation process, reduces the operation difficulty and time cost of the staff, thereby improving the work efficiency while ensuring safety.
