Abstract
Description
Technical Field
[0001] This invention relates to the field of fire door installation technology, and in particular to an installation and fixing structure and a fire door for high-speed railway station buildings. Background Technology
[0002] As an important location, the installation of fire doors in high-speed railway stations is particularly important, as fire doors can serve as devices to prevent the spread of fire in the event of a fire.
[0003] When fire doors are installed, the door frame is fixed to the wall using bent iron sheets to ensure temporary fixation. Because the iron sheets are thin, they can be covered with a coating after the door frame is installed, thus not affecting the aesthetics of the wall. However, the current method is to use screws to fix the iron sheets to the wall. This method causes the screw heads to protrude, affecting the flatness of the wall and damaging the aesthetics of the walls in public places. Summary of the Invention
[0004] The purpose of this invention is to provide an installation and fixing structure and a fireproof door for high-speed railway station buildings to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an installation and fixing structure, comprising:
[0006] A connecting component, the connecting component including a mounting section and a bending section;
[0007] A fixing plate, the fixing plate being used for connecting the installation of components, the installation section being disposed on one side of the fixing plate;
[0008] Mounting bolts are used to fix the mounting section to the fixing plate;
[0009] A plug-in block is disposed on one side of the bent section, and the outer wall of the plug-in block is provided with a tensile groove for resisting pull-out.
[0010] Preferably, an extension section for connecting the mounting section and the bending section is fixedly connected to one end of the mounting section and the bending section respectively, and the bending section is used for multi-angle bending.

[0013] Preferably, the connector includes an upper memory metal sheet, a lower memory metal sheet, and a heating element. The upper and lower memory metal sheets are respectively attached to the upper and lower surfaces of the heating element. The tensile groove is provided on the non-attached surfaces of the upper and lower memory metal sheets. The upper and lower memory metal sheets are symmetrically arranged. The inner ends of both the upper and lower memory metal sheets are connected to the inner side of the bent section. The outer ends of both the upper and lower memory metal sheets are pointed. When the heating element is powered on and heats up, the outer end of the upper memory metal sheet bends upward and the outer end of the lower memory metal sheet bends downward.
[0014] Preferably, the bent section is provided with a through hole, and the conductive wire of the heating element passes through the through hole to conduct electricity to an external power source.
[0015] Preferably, one end of the plug block is fixedly connected to the inner side of the bent section, the outer side of the bent section is provided with a stepped hole that communicates with the through hole, a T-shaped conductive post is provided in the stepped hole, the vertical end of the T-shaped conductive post is inserted into the through hole and electrically connected to the conductive wire, an insulating washer is provided between the T-shaped conductive post and the bent section, and the top plane of the T-shaped conductive post does not protrude from the outer side of the bent section.
[0016] Preferably, the mounting and fixing structure further includes a positive electrode pressure bar and a negative electrode pressure bar. During installation, the positive electrode pressure bar is connected to a positive power supply, and the negative electrode pressure bar is connected to a negative power supply. The positive electrode pressure bar and the negative electrode pressure bar respectively press down on the T-shaped conductive pillars of the positive and negative electrodes of the heating element, so that the bent section is in close contact with the wall. At the same time, the heating element is energized and heats up, and the upper and lower memory metal sheets bend and expand outward after being heated.

[0019] The technical effects and advantages of this invention are as follows:
[0020] This invention utilizes the design of connecting components and plug-in blocks. During the installation of the door frame and wall, the mounting section and fixing plate are first installed using mounting bolts. Then, the connecting component is fitted to the outer wall. At this point, the portion of the connecting component protruding from the wall can be bent to ensure a tight fit between the connecting component and the outer wall. While the bent section is in contact with the wall, pressing or hammering the bent section inserts the plug-in block into the wall, firmly connecting the bent section to the wall without any noticeable protrusion, thus maintaining the flatness of the outer wall. Furthermore, the shape-memory metal design ensures the plug-in block is firmly fixed to the wall, effectively guaranteeing the stability of the fire door installation. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1
[0033] This invention provides, for example Figure 1-3 The installation and fixing structure shown includes:
[0034] Connecting component 1, which includes mounting section 11 and bending section 13;
[0035] Fixing plate 2 is used to connect the installation of component 1, and mounting section 11 is provided on one side of fixing plate 2;
[0036] Mounting bolt 3 is used to fix the mounting section 11 to the fixing plate 2;
[0037] The plug-in block 4 is located on one side of the bent section 13, and the outer wall of the plug-in block 4 is provided with a tensile groove 41 for resisting pull-out.
[0038] Specifically, an extension section 12 for connecting the installation section 11 and the bending section 13 is fixedly connected to one end of the installation section 11 and the bending section 13. The bending section 13 is used for multi-angle bending. A round hole for inserting the installation bolt 3 is opened on one side of the installation section 11. The fixing plate 2 is groove-shaped. The installation section 11 is set in the recess of the fixing plate 2. One end of the plug block 4 is fixedly connected to one side of the bending section 13. The tensile groove 41 is serrated.
[0039] Furthermore, the connecting component 1 is made of a thin metal sheet with a thickness of 1mm. The mounting section 11, extension section 12, and bending section 13 are integrated into one sheet. The insertion block 4 is made of metal. Through the opening of the tensile groove 41, the insertion block 4 is shaped like an arrow, with the tip of the arrow pointing away from the bending section 13. The arrow shape on the shoulder of the insertion block 4 facilitates the insertion of the insertion block 4 into the interior of the wall 7. The part where the insertion block 4 connects to the bending section 13 is fixed by welding. The fixing plate 2 is set in a groove shape to store the mounting bolts 3 and prevent them from being installed. The bolt 3 protrudes from the door frame 5, and the serrated anti-tensile groove 41 provides good tensile resistance when the plug block 4 is inserted into the wall 7, thus preventing the plug block 4 from being pulled out at will, and ensuring the stability of the connection between the bent section 13 and the wall 7. Two connecting components 1 are symmetrically arranged inside the groove of the fixing plate 2. Whether the bent section 13 is bent depends on the width of the wall 7 when the door frame 5 is actually installed. When the bent section 13 protrudes from the mounting bolt 3, the bent section 13 is bent; otherwise, the bent section 13 does not need to be bent. Example 2
[0040] like Figure 4-7 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the plug-in block 4 includes an upper memory metal sheet 42, a lower memory metal sheet 43, and a heating element 44. The upper memory metal sheet 42 and the lower memory metal sheet 43 are respectively attached to the upper and lower surfaces of the heating element 44. The tensile groove 41 is provided on the non-attached surfaces of the upper memory metal sheet 42 and the lower memory metal sheet 43. The upper memory metal sheet 42 and the lower memory metal sheet 43 are symmetrically arranged. The inner ends of the upper memory metal sheet 42 and the lower memory metal sheet 43 are both connected to the inner side of the bending section 13. The outer ends of the upper memory metal sheet 42 and the lower memory metal sheet 43 are both set as pointed portions. When the heating element 44 is powered on and heats up, the outer end of the upper memory metal sheet 42 bends upward and the outer end of the lower memory metal sheet 43 bends downward. In this embodiment, both the upper shape memory metal sheet 42 and the lower shape memory metal sheet 43 are made of single-pass shape memory alloy. This shape memory alloy deforms at a relatively low temperature and can recover its original shape after heating. In this embodiment, the heating element 44 is a thin-film heating element, an aluminum foil heating element, or a tungsten wire heating element.
[0041] In this embodiment, the bent section 13 is provided with two through holes 131, and the conductive wires 45 of the positive and negative electrodes of the heating element 44 pass through the two through holes 131 respectively to connect with the external power supply.
[0042] In this embodiment, one end of the plug block 4 is fixedly connected to the inner side of the bent section 13. The outer side of the bent section 13 is provided with a stepped hole 132 that communicates with the through hole 131. A T-shaped conductive post 46 is provided in the stepped hole 132. The vertical end of the T-shaped conductive post 46 is inserted into the through hole 131 and electrically connected to the conductive wire 45. An insulating washer 47 is provided between the T-shaped conductive post 46 and the bent section 13. The top plane of the T-shaped conductive post 46 does not protrude from the outer side of the bent section 13, thus ensuring the flatness of the wall surface.
[0043] In this embodiment, the installation and fixing structure further includes a positive electrode pressure bar 8 and a negative electrode pressure bar 9. During installation, the positive electrode pressure bar 8 is connected to a positive power supply, and the negative electrode pressure bar 9 is connected to a negative power supply. The positive electrode pressure bar 8 and the negative electrode pressure bar 9 respectively press down on the T-shaped conductive posts 46 of the positive and negative electrodes of the heating element 44, so that the bent section 13 is tightly attached to the wall. At the same time, the heating element 44 is energized and heats up. The upper memory metal sheet 42 and the lower memory metal sheet 43 bend and expand outward after being heated, thereby making the plug block 4 firmly fixed on the preset hole on the wall, so that the wall will not crack during later use. Example 3
[0044] This invention provides, for example Figure 8-10 The fire door shown is a type of fireproof door for high-speed railway station buildings. The fireproof door includes the above-mentioned installation and fixing structure. The fireproof door includes a fireproof door body 6. A door frame 5 for installing the fireproof door body 6 is fitted on the outside of the fireproof door body 6. Rectangular grooves for installing fixing plates 2 are respectively opened on both sides of the door frame 5. A wall 7 for fixing the door frame 5 is fitted on the outside of the door frame 5. The wall 7 is used for inserting the plug block 4.
[0045] Furthermore, wall 7 is the wall of the high-speed railway station building. Wall 7 can be a masonry wall or a concrete wall. When wall 7 is a masonry wall, the interlocking block 4 is inserted between the cement mortar between two bricks. When wall 7 is a concrete wall, the interlocking block 4 is directly inserted into the concrete by hammering the bent section 13, or a hole is pre-drilled in the concrete wall, the hole of which fits tightly with the interlocking block 4, and then the interlocking block 4 is directly inserted into the hole. The fire door body 6 is an existing fire door. The fire door body 6 is hinged to the door frame 5. The rectangular groove in the door frame 5 is used for the filling of cement mortar after the fire door body 6 is installed. Multiple fixing plates 2 are set and symmetrically set in the rectangular grooves on both sides of the door frame 5. The parts of the fixing plates 2 that contact the inner wall of the rectangular groove are fixed by welding. Before the fire door body 6 is installed, the door frame 5 needs to be temporarily fixed and connected to the groove in the wall 7. At this time, the bending section 13 is used. The plug block 4 of the bending section 13 is inserted into the wall 7 to complete the temporary fixation of the door frame 5 to the wall 7. Then, bolts are used to permanently and firmly fix the door frame 5 to the wall 7. After that, paint is applied to cover the bending section 13. Because the bending section 13 is thin, it will not protrude obviously and will not affect the overall flatness of the wall 7. Finally, the hinges on the fire door body 6 and the door frame 5 are installed to complete the installation of the fire door body 6.
[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
