Embodiment 1
[0051] Such as Figure 1-8 As shown, the cable trench fireproof sealant construction device includes: sealing plate, the sealing plate is made of insulating material;
[0052] The sealing plate is provided with two pieces; the sealing plate is provided with a hole for the cable 8 to pass through; at least one of the sealing plates is provided with an injection port 11 to inject fireproof sealant into the sealing plate through the injection port 11 .
[0053] The cable trench fireproof sealant construction device of the present invention is used for fireproof sealant filling, which solves the problem that the fireproof sealant has poor filling compactness and affects the fireproof function, and the cable trench fireproof sealant construction device itself also has a fireproof function. The use of sealant can effectively improve the fireproof function of cables, and can be used alone for fireproofing of cable trenches. Preferably, during construction, the two sealing plates of...
Embodiment 2
[0071] Such as Figure 1-8 As shown, the cable trench fire prevention device provided by the present invention includes a firewall 7 and the cable trench fireproof sealant construction device described in the first embodiment above. The cable trench fireproof sealant construction device itself has a certain fireproof effect. After it is installed inside the firewall 7, it cooperates with the firewall 7 to form a cable trench fireproof structure, which can cooperate with the injected fireproof sealant to form a better fireproof effect. , Effectively improve the fire prevention effect of the cable.
[0072] In the cable trench fire prevention device provided by the present invention, two sealing plates are relatively blocked on both sides of the firewall 7, and a glue injection area is formed between the firewall 7 and the two sealing plates. During construction, the two sealing plates can be used in contact with each other or at a distance from one end, and the sealant will mo...
Embodiment 3
[0076] Such as Figure 1-8 As shown, the cable trench fireproof sealant construction method uses the cable trench fireproof sealant construction device described in any one of the above, and the method includes the following steps:
[0077] a. The two sealing plates of the construction device are relatively blocked on both sides of the firewall 7, and the control cable 8 passes through the holes of the two sealing plates to realize the sealing of the cable 8 and the hole;
[0078] b. Inject fireproof sealant into the space between the two sealing plates through the injection port 11 until the fireproof sealant fills the space between the two sealing plates;
[0079] c. After the injection of the fireproof sealant is completed, the injection port 11 is blocked.
[0080]Principle: The cable trench fireproof sealant construction device of the present invention is used to solve the problems of poor filling compactness and poor fireproof function when filling fireproof sealant bet...
