Description

Technical Field

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

[0002] The rapid pace of urban development means higher requirements for construction, and the increased complexity of construction projects exacerbates the occurrence of accidents on construction sites. Safety hinges on management, and accident prevention is paramount. Construction safety devices have emerged as a result. In recent years, the renovation of old residential areas has become increasingly important. During construction in these areas, the possibility of falling debris injuring people is greater due to the age of the buildings. Therefore, construction safety devices are essential to prevent accidents during renovations.

[0003] In existing technologies, when renovating old residential areas, there is generally a lack of resources to relocate the residents. Often, the renovation and resettlement of residents are carried out simultaneously. To protect the workers and original residents, multiple levels of safety nets are often installed on the construction site. However, when installing existing safety nets, lower nets are easy to install, while higher nets require workers to climb to higher scaffolding positions for installation. Furthermore, all four corners need to be secured. Workers need to wear safety harnesses when working at heights, but the safety harnesses prevent workers from walking back directly when securing the four corners. This results in a higher accident rate during the operation, causing production accidents and injuries or fatalities. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a protective device for building renovation and construction.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a construction renovation protection device, comprising a square steel frame, with long slots on both sides of the square steel frame, a fixed column plate fixed to one end of each long slot, a primary mesh hanging ring fixed to one side of the fixed column plate, a primary protective net detachably connected to the primary mesh hanging ring, an inner column fixed to the other end of the primary protective net, an outer column fixed to one side of the fixed column plate, an outer column having an unfolding air rail, an inner column having a retracting primary air rail, a sealing disc slidably connected to the inner wall of the outer column, an inner air sleeve fixed to one side of the sealing disc, a retracting secondary air rail on the inner air sleeve, a spacer fixed to the surface of the inner air sleeve, a small sealing disc slidably connected to the inner wall of the inner air sleeve, a small spacer fixed to one side of the small sealing disc, and an inner column fixed to one side of the small spacer. In the prior art, during the renovation of old residential areas, resources are generally lacking for the resettlement of residents, and often the residents' living arrangements and the renovation of the old residential area are carried out simultaneously. To protect those present... For construction workers and residents of older communities, multi-level safety nets are often installed at construction sites for personnel protection. However, while lower safety nets are easy to install, higher ones require workers to climb to higher scaffolding positions for installation, and all four corners need to be secured. Workers must wear safety harnesses while working at height, but the harnesses prevent them from walking back directly after securing the corners, leading to a higher accident rate and potential production accidents resulting in injuries or fatalities. To address this issue, this invention uses an outer column installation method. Before use, workers install the outer column on the inner wall of a square steel frame at height using a fixing plate. One end of the safety net is then fixed to the primary net hanging ring, and the other end is fixed to one end of the inner column. When the safety net needs to be deployed, an air pump is connected to the deployment air track inlet. The air pump supplies air inward, pushing the inner column and inner air sleeve out sequentially, thus deploying the safety net. This improves production safety and reduces the accident rate.

[0006] Preferably, the bottom of the square steel frame is fixed with multiple secondary support columns. Each secondary support column has a track groove on its surface, and the track groove has multiple bite grooves. A main support column is slidably connected to the surface of each secondary support column. The main support column also has a track groove on its surface. A collar is slidably connected to one end of the main support column. The collar has a rotating groove on its surface, and a lever is rotatably connected to the inner wall of the rotating groove. A pressure bite is slidably connected to the surface of the lever. In the prior art, the building material for floor protection scaffolding is generally steel pipe, which is heavy and difficult for workers to assemble. It lacks modularity and requires cranes or elevators to help workers lift the materials before securing them. This operation is also necessary for some lower floors, which leads to… When renovating old residential buildings, the roads are narrow, making it difficult for large equipment such as cranes to enter. Furthermore, the buildings are often low-rise. Demolishing walls to widen the roads would be too costly and disrupt residents' travel. To address these issues, this invention uses a ring-installation method. When workers are working on lower floors, they can first install secondary support columns at the bottom of the square steel frame. Then, by rotating a wrench, the clamping teeth disengage from the groove. Workers use pulleys to lift the square steel frame to a suitable height, and then control the wrench to rotate the clamping teeth back into the groove, thus fixing the secondary support column to the main support column. Due to the modular design of the square steel frame platform and support column components, there is no need to use a crane to assist workers in binding and assembling the structure, thereby improving production safety and increasing production efficiency.

[0007] Preferably, both ends of the square steel frame are provided with short slots, and multiple fixed hangers are detachably connected to the short slots. A ladder side steel is fixed to the bottom of each fixed hanger, and a ladder tread is fixed to one side of the ladder side steel. In the prior art, the passageways between protective scaffolding floors are relatively simple, generally consisting of makeshift ladders welded and assembled by workers themselves. The quality varies greatly, and accidents are easily caused when workers pass through. Furthermore, these ladders are directly welded to the main structure, making them immovable, cumbersome to use, and inconvenient, resulting in low production efficiency. To address these problems, this utility model solves the issue by installing ladder treads, enabling fixed hangers to be suspended from the short slots of the square steel frame of each floor's protective platform. When workers need to move between floors, the fixed hangers of the ladder can be rotated for movement, and they can be easily removed for use elsewhere. In some old residential building renovation sites, where there are many residents, to prevent residents and children from climbing the ladder out of curiosity, workers can remove and store the fixed hangers after climbing the ladder and hanging on the floor, preventing residents from accidentally entering the site, thus improving user experience and reducing the occurrence of production accidents.

[0008] Preferably, a secondary mesh hanging ring is fixed to the surface of the collar, and a secondary protective mesh is fixed to the surface of the secondary mesh hanging ring. Through the combination of multiple protective meshes, most accidents involving falling and injuring people can be avoided.

[0009] Preferably, the other end of the main support column is fixed with a fixing base plate to facilitate the fixing of the main support column to the ground or the low-rise square steel frame.

[0010] Preferably, multiple warning lights are fixed on both sides of the square steel frame to warn nearby personnel not to approach.

[0011] Preferably, the top of the ladder tread has rounded corners to prevent sharp edges from injuring or scratching workers.

[0012] Beneficial effects

[0013] 1. In existing technologies, during the renovation of old residential areas, resources are generally lacking for the resettlement of residents. Often, the renovation and resettlement of residents are carried out simultaneously. To protect both on-site workers and original residents, multi-level safety nets are typically installed at the construction site. However, existing safety nets are difficult to install. Lower nets are relatively easy to install, while higher nets require workers to climb to higher scaffolding for installation, and all four corners need to be secured. Workers must wear safety harnesses when working at heights, but securing the corners is restricted by the harnesses, preventing workers from walking directly. Returning to the site can lead to a higher accident rate during operation, causing production accidents and injuries. To address this issue, this utility model solves the problem by installing an outer sleeve column. Before use, workers install the outer sleeve column on the inner wall of the high-altitude square steel frame using a fixed column plate. One end of the protective net is then fixed to the primary net hanging ring, and the other end is fixed to one end of the inner column. When workers need to unfold the protective net, an air pump is connected to the unfolding air track inlet. The air pump supplies air inward, pushing the inner column and inner air sleeve out sequentially, thus unfolding the protective net. This improves production safety and reduces the accident rate.

[0014] 2. In existing technologies, the construction material for floor protection scaffolding is generally steel pipe, which is heavy and cumbersome for workers to assemble. It lacks modularity and requires the assistance of cranes or elevators to help workers lift the materials and then secure them. This operation is also required for some lower floors. This makes it difficult for cranes and other large equipment to enter the narrow roads of old residential areas during renovations. Furthermore, widening roads by demolishing walls would be too costly and would affect residents' travel. To address these issues, this utility model uses a ring installation method. When workers are working on lower floors, they can first install the secondary support column at the bottom of the square steel frame, then rotate the lever to disengage the clamping teeth from the groove. Workers can then use pulleys to lift the square steel frame to a suitable height, and then control the lever to rotate again to engage the clamping teeth in the groove, thus fixing the secondary support column to the main support column. Due to the modularity of the square steel frame platform and support column components, there is no need to use cranes to assist workers in assembling the scaffolding, thereby improving production safety and increasing production efficiency.

[0015] 3. In existing technologies, the access points for protective scaffolding on different floors are often rudimentary, typically consisting of makeshift ladders welded and assembled by workers themselves. These ladders vary in quality and can easily cause accidents when workers pass through. Furthermore, these ladders are directly welded to the main structure, making them immovable, cumbersome, and inconvenient to use, resulting in low production efficiency. To address these issues, this invention solves the problem by installing ladder treads. This allows for the hanging and fixing of the ladder in the short slots of the square steel frame of each floor's protective platform. When workers need to move between floors, the ladder's fixing can be rotated for movement, and it can be easily disassembled for use elsewhere. In some older residential building renovation sites, where there are many residents, to prevent residents and children from climbing the ladder out of curiosity, workers can remove and store the fixing after climbing the ladder to the next floor, preventing residents from accidentally entering the site. This improves user experience and reduces the occurrence of production accidents. Attached Figure Description

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0027] Reference Figure 1-6A construction safety device for building renovation includes a square steel frame 1. Both sides of the square steel frame 1 have elongated slots 101. A fixing column plate 2 is fixed to one end of each slot 101. A primary mesh hanging ring 201 is fixed to one side of the fixing column plate 2. A primary protective net 104 is detachably connected to the primary mesh hanging ring 201. An inner column 2011 is fixed to the other end of the primary protective net 104. An outer column 202 is fixed to one side of the fixing column plate 2. The outer column 202 has an expanding air rail 203 and an inlet primary air rail 204. A sealing disc 207 is slidably connected to the inner wall of the inner air sleeve 205. An inner air sleeve 205 is fixed to one side of the sealing disc 207. The inner air sleeve 205 has a secondary air rail 206 for intake and exhaust. A spacer 208 is fixed to the surface of the inner air sleeve 205. A small sealing disc 209 is slidably connected to the inner wall of the inner air sleeve 205. A small spacer 2010 is fixed to one side of the small sealing disc 209. An inner column 2011 is fixed to one side of the small spacer 2010. In the renovation of old residential areas, there is generally a lack of resources to relocate the residents. Often, the residents' living arrangements and the renovation of the old residential area are carried out simultaneously. To protect on-site workers and residents of older communities, construction sites often install multi-level safety nets. However, existing safety nets have limitations: lower nets are easier to install, while higher nets require workers to climb to higher scaffolding positions for installation, and all four corners need to be secured. Workers must wear safety harnesses while working at heights, but the harnesses prevent them from walking back directly after securing the corners, leading to a higher accident rate and potential injuries or fatalities. The solution is to install outer columns 202. Before use, workers install the outer columns 202 on the inner wall of the square steel frame 1 using column plates 2. One end of the safety net is then fixed to the primary net hanging ring 201, and the other end to one end of the inner column 2011. When the safety net needs to be deployed, an air pump is connected to the inlet of the deployment air track 203. The air pump supplies air inward, pushing out the inner column 2011 and inner air sleeve 205 sequentially, thus deploying the safety net. This improves production safety and reduces the accident rate. Multiple warning lights 103 are fixed on both sides of the square steel frame 1 to warn nearby personnel not to approach.

[0028] Multiple secondary support columns 307 are fixed at the bottom of the square steel frame 1. The surface of each secondary support column 307 has a track groove 301 with multiple bite grooves 308. A main support column 3 is slidably connected to the surface of the secondary support column 307. The surface of the main support column 3 has a track groove 301. One end of the main support column 3 is slidably connected to a collar 302. The surface of the collar 302 has a rotating groove 304. A lever 305 is rotatably connected to the inner wall of the rotating groove 304. A pressure bite 306 is slidably connected to the surface of the lever 305. The building materials for floor protection scaffolding are generally steel pipes, which are heavy and difficult for workers to assemble. They lack modularity and require cranes or elevators to assist workers in lifting the materials for securing them. This process is also necessary for some lower floors, which leads to… When renovating old residential buildings, the roads are often narrow, making it difficult for large equipment like cranes to access them. Furthermore, the buildings are often low-rise. Demolishing walls to widen the roads would be too costly and disrupt residents' lives. A solution is to install a collar 302. This allows workers on lower floors to first install the secondary support column 307 at the bottom of the square steel frame 1. Then, by rotating the lever 305, the clamping teeth 306 disengage from the groove 308. Workers then use pulleys to lift the square steel frame 1 to a suitable height. Finally, the lever 305 is rotated again to engage the clamping teeth 306 in the groove 308, securing the secondary support column 307 to the main support column 3. Due to the modular design of the square steel frame 1 platform and support column components, cranes are no longer needed for assembly, improving safety and increasing efficiency. The collar 302 has a secondary mesh hanging ring 303 fixed to its surface, and the secondary mesh hanging ring 303 has a secondary protective net 3010 fixed to its surface. This multi-layered protective netting helps prevent most falls and injuries. The other end of the main support column 3 is fixed with a fixing base plate 309, which facilitates the fixing of the main support column 3 to the ground or the lower square steel frame 1. The top of the ladder tread 402 is provided with a tread rounded corner 403 to avoid sharp edges of the ladder tread 402 from injuring or scratching workers.

[0029] Both ends of the square steel frame 1 are provided with short slots 102, and multiple fixed hangers 4 are detachably connected to the short slots 102. The bottom of the fixed hanger 4 is fixed with a ladder side steel 401, and a ladder step 402 is fixed to one side of the ladder side steel 401. The passage between the protective scaffolding of each floor is relatively simple, usually a simple ladder welded and built by the workers themselves. The quality is uneven, which can easily cause accidents when workers pass through. Moreover, this kind of ladder is directly welded to the main body and cannot be moved, which is cumbersome to use and lacks convenience, resulting in low production efficiency. The method of installing ladder steps 402 solves the problem, so that the short slots 102 of the square steel frame 1 of each floor's protective platform can be used to suspend the fixed hangers 4. When workers need to move between floors, the fixed hangers 4 of the ladder can be rotated and moved. They can also be removed at any time for use in other places. In some old residential building renovation sites, due to the large number of residents, in order to prevent some residents and children from climbing the ladder out of curiosity, the workers can remove and put away the fixed hangers 4 after climbing the ladder and hanging on the floor, so as to prevent residents from accidentally entering the site, thereby improving the user experience and reducing the occurrence of production accidents.

[0030] The working principle of this utility model is as follows: When workers are constructing on a lower floor, they can first install the secondary support column 307 at the bottom of the square steel frame 1, then rotate the wrench 305 to make the clamping teeth 306 disengage from the groove 308. Workers use pulleys to lift the square steel frame 1 to a suitable height, and then control the wrench 305 to rotate so that the clamping teeth 306 enter the groove 308, thus fixing the secondary support column 307 to the main support column 3. Due to the modularity of the square steel frame 1 platform and support column assembly, there is no need to use a crane to assist workers in binding and assembling. Before use, workers install the outer column 202 on the inner wall of the square steel frame 1 at a high altitude using the fixed column plate 2, and then fix one end of the protective net to the primary net hanging ring 201 and the other end to one end of the inner column 2011. When workers need to unfold the protective net, they connect the air pump to the unfolding air track. At entrance 203, the air pump supplies air inward to push out the inner column 2011 and inner air sleeve 205 in sequence, causing the protective net to unfold. The secondary net hanging ring 303 can install the secondary protective net 3010. Through the combination of multiple protective nets, most accidents of falling and injuring people can be avoided. The short slots 102 of the square steel frame 1 of each floor's protective platform can be used to suspend the fixed hanger 4. When the staff needs to move between floors, the fixed hanger 4 of the ladder can be rotated and moved. It can also be removed at any time for use in other places. In some old residential building renovation sites, due to the large number of residents, in order to prevent some residents and children from climbing the ladder out of curiosity, the staff can remove and put away the fixed hanger 4 after climbing the ladder and hanging on the floor to prevent residents from accidentally entering the site. The fixed base plate 309 facilitates the fixing of the main support column 3 to the ground or the lower square steel frame 1.
