Description

Technical Field

[0001] This utility model relates to the technical field of fire doors, specifically to an external T-shaped fire door frame. Background Technology

[0002] The "T" on a fire door is a symbol indicating the gap between the door leaf and the door frame. According to national standards, the gap between the fire door leaf and the door frame must be controlled within a certain range to ensure its sealing and fire resistance performance. The "T" symbol, typically appearing as numbers such as "2.0," "2.5," "3.0," or "3.5" on the door leaf and frame.

[0003] During the installation of T-shaped fire door frames, because the main body of the door frame is a one-piece structure, the surface of the building must be damaged before the door frame can be installed inside the building. Then, foaming agent is used to seal the gaps between the building and the door frame. However, in the event of a fire, the foaming agent will melt directly, affecting the fire-blocking effect of the fire door. Summary of the Invention

[0004] The purpose of this utility model is to provide an external T-shaped fireproof door frame to solve the above-mentioned defects caused by the prior art.

[0005] An external T-shaped fireproof door frame includes a door frame panel, an alloy clamping plate one, and an alloy clamping plate two. The alloy clamping plate one is symmetrically arranged on the outer side of the door frame panel, and the outer side of the door frame panel has symmetrically opened pin holes. A positioning mechanism is provided on the outer side of the door frame panel. The positioning mechanism installs the door frame panel and the alloy clamping plate one in stages on the outer side of the building, thereby reducing the gap between the door frame panel and the building. A clamping mechanism is provided on the outer side of the alloy clamping plate one. The clamping mechanism adjusts the clamping spacing according to the thickness of the building wall, improving the flexibility of the door frame panel during positioning.

[0006] Preferably, the positioning mechanism includes bolts, positioning holes, rock wool boards, nuts, and double-sided adhesive strips. Positioning holes are evenly spaced on the outer side of the first alloy clamping plate. Bolts are installed inside the positioning holes, and nuts are connected to the tail ends of the bolts. Double-sided adhesive strips are connected to both the upper and lower sides of the door frame plate. Rock wool boards are connected to the top ends of the double-sided adhesive strips. Nuts are evenly spaced on one side of the second alloy clamping plate.

[0007] Preferably, the first alloy clamp is connected to the second alloy clamp by bolts that are connected at equal intervals.

[0008] Preferably, the clamping mechanism includes an alloy clamping plate one, an alloy clamping plate two, a silicone rubber plate, flat steel rods, and guide grooves.

Guide grooves are provided at equal intervals on one side of the alloy clamping plate one.

[0009] Preferably, the alloy clamping plate two is connected to the alloy clamping plate one by flat steel rods that are equally spaced on one side.

[0010] Preferably, the alloy clamp plate 2 is connected to the outer side of the flat steel rod through guide grooves that are opened at equal intervals.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. During use, the modular and split structure facilitates the fine-tuning, grinding, or cutting of the outer sides of alloy clamping plate one and alloy clamping plate two according to the size differences of the door slots of the building, thereby improving the convenience of installation in the same building.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, an external T-shaped fireproof door frame includes a door frame panel 1, an alloy clamping plate 1 2, and an alloy clamping plate 2 6. The alloy clamping plate 1 2 is symmetrically arranged on the outer side of the door frame panel 1. The door frame panel 1 has symmetrically opened pin holes 11 on the outer side. The door frame panel 1 has a positioning mechanism 7 on the outer side. The positioning mechanism 7 installs the door frame panel 1 and the alloy clamping plate 1 2 on the outer side of the building in stages, thereby reducing the gap between the door frame panel 1 and the building. The alloy clamping plate 1 2 has a clamping mechanism 12 on the outer side. The clamping mechanism 12 adjusts the clamping spacing according to the thickness of the building wall, improving the flexibility of the door frame panel 1 during the positioning process.

[0023] In this embodiment, the positioning mechanism 7 includes bolts 3, positioning holes 4, rock wool boards 5, nuts 9, and double-sided adhesive strips 13. Positioning holes 4 are evenly spaced on the outer side of the alloy clamping plate 1 2. Bolts 3 are installed inside the positioning holes 4. Nuts 9 are connected to the tail end of the bolts 3. Double-sided adhesive strips 13 are connected to both the upper and lower sides of the door frame plate 1. Rock wool boards 5 are connected to the top end of the double-sided adhesive strips 13. Nuts 9 are evenly spaced on one side of the alloy clamping plate 2 6.

[0024] In this embodiment, the alloy clamping plate 2 is connected to the alloy clamping plate 6 by bolts 3 that are connected at equal intervals. The bolts 3 simultaneously lock the alloy clamping plate 2, the alloy clamping plate 6, and the wall.

[0025] In this embodiment, the clamping mechanism 12 includes an alloy clamping plate 2, an alloy clamping plate 6, a silicone rubber plate 8, a flat steel rod 10, and a guide groove 14. The silicone rubber plate 8 is attached to one side of the alloy clamping plate 2, and the alloy clamping plate 6 is connected to the other side of the silicone rubber plate 8. The flat steel rod 10 is welded at equal intervals on one side of the alloy clamping plate 2, and bolts 3 are connected through the outer side of the flat steel rod 10. The guide groove 14 is provided at equal intervals on one side of the alloy clamping plate 2.

[0026] In this embodiment, the alloy clamping plate 2 is connected to the alloy clamping plate 2 by flat steel rods 10 arranged at equal intervals on one side, and the flat steel rods 10 are used to position and guide the connection between the alloy clamping plate 2 and the alloy clamping plate 2.

[0027] In this embodiment, the alloy clamp plate 6 is connected to the outside of the flat steel rod 10 through guide grooves 14 with equal spacing. The guide grooves 14 are used to position and store the flat steel rod 10, reducing the occurrence of corrosion.

[0028] In practical applications, this type of external T-shaped fire door frame includes the following tasks:

[0029] Step 1: During use, firstly, a portion of alloy clamp 12 is attached to one side of the wall, and the flat steel rod 10 on one side of alloy clamp 12 is connected to the guide groove 14 corresponding to one end of alloy clamp 26. Alloy clamp 26 is attached to the other side of the wall. Then, the distance between alloy clamp 12 and alloy clamp 26 is adjusted, and the wall is clamped and positioned by alloy clamp 12 and alloy clamp 26 on both sides.

[0030] Step 2: At the same time, a silicone rubber plate 8 is set between alloy plate 1 2 and alloy plate 2 6. The silicone rubber plate 8 blocks the gap between alloy plate 1 2 and alloy plate 2 6 (or the gap between alloy plate 1 2 and alloy plate 2 6 can be blocked according to the gap of the building). The silicone rubber plate 8 is compressed and deformed according to the irregular shape of the gap.

[0031] Step 3: At the same time, rock wool boards 5 are installed on the upper and lower sides of the door groove of the building. The rock wool boards 5 are used to press the alloy plywood 1 2, alloy plywood 2 6 and the upper and lower sides of the door frame board 1, thereby reducing the gap between the building and the alloy plywood 1 2, alloy plywood 2 6 and door frame board 1. At the same time, the double-sided adhesive strip 13 installed on the top of the door frame board 1 is used to bond to the outside of the rock wool board 5 to prevent the rock wool board 5 from shaking after installation (cement can fill the remaining gaps and reduce the gap between the door frame board 1 and the building).

[0032] Step 4: The operator installs the bolts 3 of the appropriate length inside the positioning holes 4, and sequentially inserts them through the alloy clamping plate 1 2, the flat steel rod 10, and the alloy clamping plate 2 6, so that the tail end of the bolt 3 is locked with the nut 9 corresponding to one side of the alloy clamping plate 2 6. The door frame plate 1 is then welded to the outer side of the alloy clamping plate 1 2. Welding can be performed after the alloy clamping plate 1 2 is fixed to the wall, which improves the accuracy of welding and joining of the door frame plate 1.

[0033] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
