Detailed Description
The present application is described in further detail below with reference to figures 1-7.
The embodiment of the application discloses a bridge frame fire wall penetrating mounting structure. Referring to fig. 1 and 2, the bridge through firewall mounting structure includes a mounting channel 2 penetrating through the firewall 1 and a bridge 3 penetrating through the mounting channel 2, wherein the bridge 3 is used for a cable 4 to penetrate through.
Example 1
Referring to fig. 1, for the purpose of conveniently penetrating the bridge frame 3, the cross-sectional area of the installation channel 2 is larger than that of the bridge frame 3, and the cross-sectional area of the installation channel 2 is controlled to be less than or equal to 0.48m2It is possible to avoid excessive influence on the structural strength of the firewall 1. The fireproof filling material 5 is filled between the bridge frame 3 and the inner wall of the installation channel 2, and in the embodiment, the fireproof filling material 5 is fireproof rock wool. On one hand, the fireproof filling material 5 enables the bridge frame 3 to be kept at a fixed position in the installation channel 2, and can absorb the vibration of the bridge frame 3 and increase the installation stability of the bridge frame 3; on the other hand, the fireproof filler 5 has excellent fireproof performance, and ensures that the bridge frame fireproof wall penetrating mounting structure has the function of preventing fire from spreading between fireproof areas on two sides of the fireproof wall.
Referring to fig. 1 and 2, fire protection plates 6 are installed on both sides of a fire protection wall 1 through fixing connectors 9. The middle part of the fireproof plate 6 is provided with an abdicating through hole 62, the shape of the abdicating through hole 62 is the same as the shape of the cross section of the bridge frame 3, and the bridge frame 3 penetrates through the abdicating through hole 62. The fire prevention plate 6 may be a plate made of a non-combustible material such as a steel plate or a cement plate. The fireproof plate 6 is thin, and the abdicating through hole 62 with high size matching degree with the bridge frame 3 is easier to process because the abdicating through hole 62 is easier to process.
Referring to fig. 1 and 2, the fire protection plate 6 of the present embodiment is made of steel plate, which has certain fire resistance and decoration, and is beneficial to improving the fire resistance of the bridge frame through the fire protection wall mounting structure. During installation construction, firstly, the bridge frame 3 is penetrated in the installation channel 2 and filled with fireproof fillers 5, so that the bridge frame is preliminarily fixed by 3 times. Because the fireproof filling material 5 has certain pores, the filling thickness of the fireproof filling material 5 can be slightly larger than the depth of the installation channel 2 during filling, and after the subsequent installation of the fireproof plate 6, the fireproof filling material 5 can be extruded and filled compactly, so that the internal space of the installation channel 2 is fully filled. Then, the periphery of the opening of the installation channel 2 is coated with fireproof mud to form a first fireproof sealing part 7, the fireproof plate 6 is covered, and the fireproof plate 6 is fixed through a fixing connecting piece 9, so that the fireproof plate 6 is firmly installed, and the opening of the installation channel 2 is sealed. Finally, fireproof mud is coated around the bridge frame 3 to form a second fireproof blocking part 8 for blocking a gap between the bridge frame 3 and the abdicating through hole 62. Firewall 6, first fire prevention shutoff portion 7 and 8 three cooperatees of second fire prevention shutoff portion for 1 both sides fire prevention district of preventing wall is by fully separating, has greatly promoted the fire behavior, and even if the local fire prevention mud that appears of first fire prevention shutoff portion 7 or second fire prevention shutoff portion 8 is not hard up, can not cause too big negative effects to the whole fire behavior that the crane span structure passed and prevents that wall mounting structure.
Referring to fig. 2 and 3, the fixing connector 9 for mounting the fire shield 6 is not limited, and a screw, an expansion screw, or other common connectors may be selected, and in this embodiment, the fire shield 6 is fixed by an anchor rod 91 and a fastening nut 92. The anchor rods 91 are distributed at four corners of the fireproof plate 6, one end of each anchor rod is inserted into the fireproof wall 1, the other end of each anchor rod penetrates through the first fireproof sealing part 7 and the fireproof plate 6 in sequence, and the tail end of each anchor rod is connected with a fastening nut 92 in a threaded mode. The tightening action of the four corners of the fireproof plate 6 can be adjusted by screwing the tightening nuts 92, so that the fireproof plate 6 is firmly installed, and the gap between the fireproof plate 6 and the fireproof filling material 5 and the first fireproof sealing part 7 can be reduced.
Referring to fig. 4, according to different actual construction occasions, a suitable auxiliary fixing mode can be selected to support and fix the bridge frame 3, so as to increase the installation stability of the bridge frame 3. In the embodiment, a rectangular frame-shaped bracket 31 and a suspension rod 32 are selected, the bracket 31 is sleeved on the bridge frame 3, the suspension rod 32 is connected to the top of the bracket 31, and one end of the suspension rod 32, which is far away from the bracket 31, is fixed on a ceiling, so that the bridge frame 3 can be uniformly stressed at any position in the length direction. For the purpose of reducing the vibration of the bridge 3, the distance between the hanging rod 32 nearest to the firewall 1 and the wall is preferably not more than 1 meter.
Example 2
Example 2 differs from example 1 in that: the fireproof plate 6 is formed by splicing a plurality of block plates 61.
Referring to fig. 5 and 6, the fire-proof plate 6 of the present embodiment includes two sub-plates 61, and each sub-plate 61 is provided with a relief notch 611. After the two sub-boards 61 are assembled, the two abdicating notches 611 form an abdicating through hole 62 together. Compare with monoblock PLASTIC LAMINATED 6, this kind of PLASTIC LAMINATED 6 that forms is assembled by a plurality of block daughter boards 61 is more nimble when the installation, can receive the space restriction in construction site less. Referring to fig. 6, when the fire prevention plate 6 of the present embodiment is installed, the two sub-plates 61 may be split in parallel.
Referring to fig. 7, in order to increase the splicing firmness between the sub-boards 61, a rib is arranged on the edge of one sub-board 61, and a strip-shaped groove for the rib to be clamped into is arranged on the edge of the other sub-board 61. So, two daughter boards 61 splice the back, and the strip groove is gone into to the bead card, and area of contact is bigger between two daughter boards 61, and difficult not hard up has also guaranteed to have sufficient sealed isolation.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
