Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically a detachable and reusable edge protection device. Background Technology

[0002] In today's construction industry, with the continuous advancement of building technology and the increasing diversification of building forms, high-rise buildings and structurally complex building projects are becoming more and more common. The main structures of these buildings often employ reinforced concrete frame structures or frame-shear wall structures, and to enhance the building's aesthetics and functionality, glass curtain walls are frequently chosen for the exterior design. However, the window sill height of glass curtain walls often fails to meet the relevant regulations regarding edge protection height. This leads to a problem: after the completion of the structural construction and before the installation of the glass curtain wall, the entire facade of the building is in a state of openness, lacking necessary protection.

[0003] This situation of being exposed to the elements poses a significant safety hazard to construction work. Without effective edge protection measures, construction workers face an extremely high risk of falling while working at heights, which not only threatens their lives but also severely impacts the construction project. Therefore, how to effectively implement edge protection and ensure construction safety has become a crucial technical issue that urgently needs to be addressed in the construction industry.

[0004] Traditional edge protection measures often employ steel pipes and couplers for erection. However, this method has several shortcomings in practical application. First, due to the large building area and the potential need for edge protection on each floor, a large number of steel pipes and couplers are required. This not only increases the difficulty of material turnover but also significantly raises construction costs. Second, the steel pipe erection process is relatively crude, resulting in poor stability and difficulty meeting increasingly stringent safety protection requirements. Furthermore, in actual construction, insufficient worker responsibility or improper operation may lead to loose steel pipe coupler connections or the steel pipes being placed haphazardly at the erection site without reinforcement, all of which further reduce the safety of edge protection. Utility Model Content

[0005] The present invention aims to overcome the defects of the prior art and provide a detachable and reusable edge protection device to solve the safety protection problem in the air-to-ground state.

[0006] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0007] A detachable and reusable edge protection device, characterized in that it comprises:

[0008] Iron plate, used as the base support for the protective device, with fixing holes on it;

[0009] Expansion bolts are used to fix the iron plate to the existing structure by passing through the fixing holes on the iron plate;

[0010] The column is welded to the iron plate and has a screw cap 4 for threading a steel wire rope.

[0011] The steel wire rope, threaded onto the nut, forms the main component of the edge protection;

[0012] The plastic sleeve is threaded onto the steel wire rope, serving both a protective and aesthetic purpose.

[0013] The removable and reusable edge protection device is characterized in that: the iron plate has a size of 150mm×150mm×3mm, and small holes are left at the four corners for installing expansion bolts.

[0014] The detachable and reusable edge protection device is characterized in that: the expansion bolts are M12 in size, which firmly fix the iron plate to the existing structure.

[0015] The detachable and reusable edge protection device is characterized in that the iron plates are arranged at 2m intervals.

[0016] The detachable and reusable edge protection device is characterized in that: the diameter of the steel pipe column is 48mm, the height is uniformly adjusted according to the height of the existing enclosure structure and the setting height of the steel wire rope, and a screw cap is welded on the column in advance at the setting position of the steel wire rope for threading the steel wire rope.

[0017] The detachable and reusable edge protection device is characterized in that: the diameter of the steel wire rope is 8mm, and its two ends are passed through the screw caps and tightened to keep the steel wire rope in a taut state, thereby forming effective edge protection.

[0018] The detachable and reusable edge protection device is characterized in that: the length of the plastic sleeve matches the setting height of the steel wire rope, and after being threaded onto the steel wire rope, it is tightened and fixed at the edge protection position together with the steel wire rope.

[0019] The beneficial effects of this utility model are as follows: As can be seen from the above technical solution, this application provides a detachable and reusable edge protection device. Edge protection railings are constructed by threading steel wire ropes through plastic sleeves. Compared to traditional steel pipe and fastener erection, this method significantly reduces construction costs while ensuring high construction quality. It also offers high construction efficiency, resulting in a good overall appearance after construction, and the materials can be reused. Furthermore, traditional steel pipe and fastener erection methods, due to insufficient worker responsibility, may result in loose connections or haphazard placement of steel pipes without reinforcement. This application, using welded steel pipes, fully meets normal edge protection requirements. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0025] like Figure 1-3 As shown: A detachable and reusable edge protection device, comprising:

[0026] Iron plate 1 is used as the base support for the protective device and has fixing holes on it;

[0027] Expansion bolts 2 are passed through the fixing holes on the iron plate to fix the iron plate to the existing structure;

[0028] The column 3 is welded to the iron plate and is provided with a screw cap 4 for threading a steel wire rope.

[0029] Steel wire rope 5 is threaded onto the nut and forms the main component of the edge protection;

[0030] The plastic sleeve 6 is threaded onto the steel wire rope, serving both a protective and aesthetic purpose.

[0031] The iron plate measures 150mm × 150mm × 3mm, with small holes at the four corners for installing expansion bolts.

[0032] The expansion bolts are M12 in size, which are used to firmly fix the iron plate to the existing structure.

[0033] The iron plates are set at 2m intervals.

[0034] The diameter of the steel pipe column is 48mm, and the height is adjusted uniformly according to the height of the existing enclosure structure and the installation height of the wire rope. In addition, screw caps are welded on the column in advance at the installation position of the wire rope for threading the wire rope.

[0035] The steel wire rope has a diameter of 8mm. After passing through the nuts at both ends, it is tightened to keep the steel wire rope taut and form effective edge protection.

[0036] The length of the plastic sleeve is matched with the installation height of the steel wire rope. After being threaded onto the steel wire rope, it is tightened and fixed at the edge protection position along with the steel wire rope, which not only protects the steel wire rope from damage, but also improves the overall aesthetics of the site.

[0037] According to the "Technical Specification for Safety of High-Altitude Operations in Building Construction" (JGJ80-2016), when guardrails are used for edge protection, the protection height should be 1200mm. Key construction technical parameters are as follows:

[0038] 1. When the height of the existing enclosure structure is between 80cm and 120cm, a steel wire rope shall be installed at the 120cm position;

[0039] 2. When the height of the existing enclosure structure is between 40-80cm, install two steel wire ropes at 120cm and 80cm.

[0040] 3. When the height of the existing enclosure structure is between 20-40cm, install three steel wire ropes at 40cm, 80cm, and 120cm.

[0041] The main construction process and technical requirements are as follows:

[0042] Step 1: Measure and lay out the lines. Determine the number and location of protective steel wire ropes based on the existing enclosure structure height, ensuring that the steel plates are at the same elevation and on the baseline.

[0043] Step 2: Fix the iron plates; On the established uniform baseline, set the iron plates at 2m intervals. The iron plates are 150mm*150mm*3mm in size, with small holes at the four corners, and are fixed to the existing structure with M12 expansion bolts.

[0044] Step 3: Column fabrication; The columns are made of 48mm diameter steel pipes. The column height and the wire rope setting height are unified according to the baseline height. The screw caps are welded in advance at the wire rope setting position for wire rope threading. The height of the column after installation is uniformly set to exceed the wire rope by 15cm to ensure overall aesthetics.

[0045] Step 4: Column welding; After the columns are fabricated, they are welded to the iron plate that is fixed to the existing structure.

[0046] Step 5: Pull the steel wire rope; according to the set height, thread an 8mm steel wire rope through the screw cap welded to the column. After installation, pull the steel wire rope to keep it taut.

[0047] Step 6: Thread the plastic sleeve; while threading the steel wire rope, prepare the plastic sleeve and thread it at the height where the edge protection is set up.

[0048] Repeat the above steps to complete the edge protection for the other floors.

[0049] This application can save construction costs. Compared with the traditional steel pipe and fastener erection method, this solution uses steel wire ropes threaded through plastic sleeves to construct the edge protection system, which significantly reduces material and construction costs.

[0050] Secondly, it helps ensure construction quality. Precise measurement, layout, and fixing processes ensure the stability and reliability of the edge protection device, thus effectively guaranteeing construction quality.

[0051] Furthermore, it improves construction efficiency. Due to its convenient construction methods, the erection and dismantling of edge protection can be completed quickly, thus significantly increasing construction efficiency. At the same time, once the protective devices are installed, the overall appearance of the site is good, contributing to a better construction image.

[0052] At the same time, it also enables the reuse of materials. The materials used, such as steel wire ropes, plastic sleeves, and iron plates, can all be reused, further reducing construction costs and material waste, which is in line with the concept of green construction.

[0053] Finally, this application fully meets the requirements for edge protection. Traditional steel pipe fastener erection methods may have problems such as loose connections or inadequate reinforcement measures, while this solution ensures the robustness and stability of the edge protection device by welding iron components to steel pipes, greatly improving construction safety.

[0054] The above are merely embodiments provided in this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
