Description

Technical Field

[0001] This utility model relates to the field of factory construction technology, and in particular to a novel fire prevention device for the interior of a liquid chlorine plant. Background Technology

[0002] During the construction of liquid chlorine plants, firewalls are often used as partitions for the interior walls. Fire doors and matching door frames are often installed on the firewalls. The thickness of the firewall varies depending on its fire resistance rating, while the thickness of the door frame cannot be arbitrarily changed. Therefore, the thickness of the firewall is often greater than that of the door frame. After the decorative surfaces on both sides of the wall are finished, they can easily form external corners with the door frames. During use, because the external corners of the decorative surfaces protrude from the door frames, they are easily bumped and cracked, affecting the overall quality and appearance of the wall, which can easily cause fire hazards and thus affect the normal and stable production of the liquid chlorine process. Utility Model Content

[0003] The purpose of this invention is to provide a novel fire prevention device for the interior of a liquid chlorine plant, in order to solve the technical problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel fireproof device for the interior of a liquid chlorine plant includes a firewall, a steel door frame mounted on the firewall, and a fireproof door within the steel door frame. The firewall has a doorway, and the steel door frame and fireproof door are located within the doorway. The fireproof door is hinged to the steel door frame. The firewall includes vertically reinforcing columns on both sides of the doorway opening, a light steel keel vertically mounted on the side of the reinforcing columns away from the doorway, and decorative panels on both sides of the reinforcing columns and the light steel keel. The steel door frame includes a main steel frame and a sub-steel frame, which are fixedly installed side-by-side along the thickness direction of the firewall. The subframe includes two C-shaped subframes and two connecting plates. Each C-shaped subframe includes a web and two leg plates. The two C-shaped subframes are arranged opposite each other with openings along the thickness direction of the firewall. An adjustment joint is provided between the two C-shaped subframes to adjust the thickness of the steel subframe. The connecting plates are strip steel plates with the same height as the C-shaped subframes. The two connecting plates are respectively located inside the adjustment joints on both sides of the steel subframes. The two sides of the connecting plates are welded and fixed to the inner sides of the C-shaped subframe leg plates on both sides of the adjustment joints. A guide rod is provided between the two C-shaped subframes. The two ends of the guide rod are welded and fixed to the inner sides of the webs of the two C-shaped subframes.

[0006] Furthermore, a second connecting plate is provided on the side of the steel main frame away from the fire door. Multiple fixed steel bars are provided between the steel main frame and the reinforcing column, and between the steel sub-frame and the reinforcing column. One end of the multiple fixed steel bars is welded and fixed perpendicularly to the reinforcing column, and the other end is welded and fixed to the first connecting plate and the second connecting plate on the adjacent side, respectively.

[0007] Furthermore, the light steel keel has a C-shaped structure, with the height and width of the reinforcing column and the light steel keel being flush, and the light steel keel abutting against the reinforcing column.

[0008] Furthermore, the side of the light steel keel that abuts against the reinforcing column is provided with a vertically elongated groove and a raised strip, which are interlocked with each other.

[0009] Furthermore, the steel main frame has a vertically extending limiting groove at the inner corner of the exterior side, and multiple hinges are provided on the exterior side of the steel main frame, through which the fire door is hinged to the steel main frame.

[0010] Furthermore, the guide rod includes an inner tube and an outer tube, with the outer tube sleeved on the inner tube and slidably connected to it.

[0011] Furthermore, the decorative panel is flush with the height of the light steel keel, and the decorative panels on both sides of the firewall abut against the steel main frame and the steel sub-frame, respectively.

[0012] Furthermore, the internal cavities of the firewall and steel door frame are filled with fireproof rock wool.

[0013] Compared with the prior art, this utility model has the following features and beneficial effects:

[0014] This utility model features a steel main frame and a steel sub-frame arranged side-by-side along the thickness direction of a firewall. The steel sub-frame includes two C-shaped sub-frames with openings facing each other along the firewall's thickness direction and two connecting plates. An adjustment gap is provided between the two C-shaped sub-frames to facilitate changing the spacing between them. This allows for adjusting the thickness of the steel sub-frame according to different firewall thicknesses, ensuring that the overall thickness of the steel door frame is greater than the firewall thickness. This prevents the decorative panels on both sides of the firewall from forming an inside corner with the steel door frame, avoiding the formation of an outside corner when the firewall thickness exceeds the steel door frame. This prevents the outside corners of the decorative panels from protruding from the steel door frame during use, which can easily be bumped, cracked, and affect the overall quality and appearance of the wall. Furthermore, the added steel sub-frame can form a unified whole with the steel main frame, offering impact resistance, convenient installation, and aesthetically pleasing finishes. It has significant promotional and practical value, and its widespread application will generate substantial economic benefits. Attached Figure Description

[0017] To make the technical means, innovative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.

[0018] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model. They are all illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0019] This utility model discloses a novel fire prevention device for the interior of a liquid chlorine plant, such as... Figure 1 As shown, the device includes a firewall, a steel door frame mounted on the firewall, and a fire door 1 mounted inside the steel door frame. The thickness of the steel door frame is greater than the thickness of the firewall. A door opening is provided in the firewall. The steel door frame and the fire door 1 are located inside the door opening. The fire door 1 is hinged to the steel door frame. The firewall includes vertically arranged reinforcing columns 2 on both sides of the door opening, a light steel keel 3 vertically arranged on the side of the reinforcing columns 2 away from the door opening, and decorative panels 4 arranged on both sides of the reinforcing columns 2 and the light steel keel 3.

[0020] The light steel keel 3 is a C-shaped structure made of bent steel plate. The height and width of the reinforcing column 2 and the light steel keel 3 are the same. The light steel keel 3 abuts against the reinforcing column 2. The side of the light steel keel 3 that abuts against the reinforcing column 2 is provided with a vertically continuous groove and a protrusion. The groove and the protrusion are interlocked with each other. The steel door frame includes a steel main frame 5 and a steel sub-frame 6. The steel main frame 5 and the steel sub-frame 6 are fixedly installed side by side along the thickness direction of the firewall. The steel main frame 5 and the steel sub-frame 6 are respectively located on the outdoor side and the indoor side.

[0021] The steel main frame 5 has a vertically extending limiting groove 10 at the inner corner of the exterior side. The steel main frame 5 has multiple hinges 11 on the exterior side. The fire door 1 is hinged to the steel main frame 5 through the hinges 11. When the fire door 1 is closed, one side of the fire door 1 is placed in the limiting groove 10. The steel subframe 6 includes two C-shaped subframes 601 and two connecting plates 602. The C-shaped subframe 601 is a C-shaped structure made of galvanized steel sheet bent into shape. The C-shaped subframe 601 includes a web plate and two leg plates. The two C-shaped subframes 601 are arranged opposite each other with openings along the thickness direction of the firewall.

[0022] Both sides of the steel subframe 6 are provided with adjustment slots to adjust the thickness of the steel subframe 6 along the thickness direction of the firewall. The connecting plate 602 is a strip steel plate with the same height as the C-shaped subframe 601. The two connecting plates 602 are respectively located inside the adjustment slots on both sides of the steel subframe 6. The two sides of the connecting plate 602 are welded and fixed to the inner side of the leg plate of the C-shaped subframe 601 on both sides of the adjustment slot. The sum of the width of the connecting plate 602, twice the width of the leg plate of the C-shaped subframe 601, and the width of the steel main frame 5 is greater than the thickness of the firewall. By setting the adjustment slots, the distance between the two C-shaped subframes 601 is changed, which makes it easy to adjust the thickness of the steel subframe 6 according to different firewall thicknesses, so that the overall thickness of the steel door frame is greater than the thickness of the firewall.

[0023] A guide rod 7 is provided between the two C-shaped subframes 601. The guide rod 7 includes an inner tube and an outer tube. The outer tube is sleeved on the inner tube and slidably connected to the inner tube. The two ends of the guide rod 7 are welded and fixed to the inner side of the web of the two C-shaped subframes 601 respectively. By setting the guide rod 7 between the two C-shaped subframes 601, the alignment accuracy is improved when changing the distance between the two C-shaped subframes 601. A connecting plate 8 is provided on the side of the steel main frame 5 away from the fire door 1. Multiple fixing steel bars 9 are provided between the steel main frame 5 and the reinforcing column 2, and between the steel subframe 6 and the reinforcing column 2.

[0024] Multiple fixed steel bars 9 are welded and fixed at one end to the reinforced column 2 vertically, and at the other end to the connecting plate 602 and connecting plate 8 on the adjacent side, respectively, so that the steel sub-frame 6 and the steel main frame 5 are welded to the reinforced column 2. The decorative panel 4 is a 12mm thick gypsum board. The height of the decorative panel 4 is flush with the light steel keel 3. The decorative panels 4 on both sides of the light steel keel 3 abut against the steel main frame 5 and the steel sub-frame 6, respectively, thereby sealing the gap between the firewall and the steel door frame. The internal cavity of the firewall and the steel door frame is filled with fireproof rock wool 12.

[0025] During construction, reinforced columns 2 and light steel keel 3 are fabricated and installed according to the thickness of the firewall in the design. The spacing between the two C-shaped subframes 601 is adjusted according to the overall thickness of the firewall, and connecting plate 602 is welded. Then, the steel subframe 6 and steel main frame 5 are fixed so that the total thickness of the steel subframe 6 and steel main frame 5 is greater than the overall thickness of the firewall. Then, fireproof rock wool 12 is filled into the internal cavity of the firewall and steel door frame. Plasterboard is pasted on both sides of the light steel keel 3 and reinforced columns 2 so that a small inside corner is formed between the steel door frame and the plasterboard. Then, the fire door 1 is hinged to the steel main frame 5 and installed using hinge 11.

[0026] This utility model uses a steel main frame 5 and a steel sub-frame 6 arranged side by side along the thickness direction of the firewall. The steel sub-frame 6 includes two C-shaped sub-frames 601 with openings opposite each other along the thickness direction of the firewall and two connecting plates 602. An adjustment gap is left between the two C-shaped sub-frames 601, so as to facilitate changing the spacing between the two C-shaped sub-frames 601. This allows the thickness of the steel sub-frame 6 to be adjusted according to different firewall thicknesses, so that the overall thickness of the steel door frame is greater than the thickness of the firewall.

[0027] The decorative panels 4 on both sides of the firewall form an inside corner with the steel door frame. This avoids the situation where the firewall thickness is greater than the steel door frame, resulting in an outside corner between the decorative panels 4 and the steel door frame. This prevents the outside corner of the decorative panels 4 from protruding from the steel door frame during use, which could easily be bumped, cracked, and affect the overall quality and appearance of the wall, potentially causing a fire hazard. Furthermore, the added steel subframe 6 can form a whole with the main steel frame, providing the benefits of impact resistance, convenient installation, and a neat finish.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
