Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a fireproof blocking device which can be shaped and reused. Background Art

[0002] According to the fire protection acceptance specification, the casing through the floor needs to be fireproofed. The utility model patent with the authorization announcement number CN210661692U discloses a fireproof sealing device inside the wall casing and a wall casing construction structure. It specifically discloses a filler part and a pusher part. The pusher part cooperates with the material cavity of the filler part. The filler part is a hollow cylindrical body with a fan-shaped ring cross section, including an inner shell and an outer shell. The inner shell, the outer shell and the two side surfaces together form a hollow cylindrical body with upper and lower openings. The connection between the inner shell and the two side surfaces is hinged on one side and fixed by a snap connection on the other side. The pusher part is a fan-shaped ring body that cooperates with the hollow cylindrical body. When the pusher part is inserted into the hollow cylindrical body, all the fireproof materials in the hollow cylindrical body are pushed out. The above patent has high sealing density and is easy to construct.

[0003] However, the above patent is troublesome to insert and cooperate with the pushing part and the filling part during use. In addition, there is a lack of a device for compacting the gap between the sleeve and the pipe, so the density of the fireproof material needs to be improved. Utility Model Content

[0010] Beneficial effects:

[0011] 1. In the present invention, by arranging the arc-shaped door frame, the inner slide groove, the outer slide groove, the inner slide plate, the outer slide plate, the sealing plate and the push plate, the relative sliding of the inner slide plate and the outer slide plate can be utilized to open the cavity, so as to facilitate and quickly realize the addition of the sealing material. At the same time, the outer slide plate drives the push plate to send the sealing material into the gap through the sealing plate. In addition, the sealing material filled in the gap is compacted by the sliding inner slide plate, thereby greatly improving the sealing density. Combined with the 90° hinge and the opening direction toward the bottom of the column, it is convenient to discharge the sealing material from the cavity, and it can also increase the contact area with the sealing material in the gap, thereby improving the compaction efficiency and effect. In addition, it can also facilitate the automatic resetting of the sealing plate. The specific process is as follows: first, by moving toward the arc-shaped door frame The outer slide is then moved upwards to the top side of the slide, so that the outer slide and the inner slide are staggered to open the cavity, and then the sealing material is added to the cavity, and the outer slide is moved in the opposite direction to close the cavity, and the outer slide and the inner slide are synchronously slid to the bottom ends of the outer and inner slide grooves, and then the curved door frame is inserted into the gap to be sealed. The appropriate insertion depth can be selected according to the actual situation, and then the outer slide is slid down and the sealing material in the cavity is squeezed by the push plate to open the sealing plate, and the sealing material is injected into the gap through the sealing plate until the sealing material is completely out of the cavity and the sealing plate is closed. Finally, the inner template is lowered and the sealing material in the gap is compacted by the sealing plate until the lower end of the inner slide is flush with the lower end of the outer slide. At this time, the curved door frame is pulled out and waits for the next addition of sealing material.

[0012] 2. In the present invention, by setting the extrusion plate, the extrusion rod and the length of the extrusion rod not less than the length of the inner slide or the outer slide, the sealing material in the cavity can be discharged conveniently to improve efficiency. At the same time, the extrusion plate can be used to compact the sealing material in the gap to further improve the sealing density.

[0013] 3. In the present invention, the setting of two push rods can facilitate the sliding control of the inner and outer slides. Combined with the setting of the push rods installed in the middle of the inner or outer slides, it can ensure that the inner and outer slides are subjected to balanced forces when sliding. The setting of the handle can facilitate holding, improve the pushing and pulling efficiency of the push rods, and at the same time limit the sliding displacement of the inner and outer slides to prevent them from escaping from the inner and outer slide grooves.

[0014] 4. In the present invention, the installation groove, buffer assembly and roller are arranged to reduce the friction between the inner slide and the outer slide and the pipe and the casing respectively, which facilitates the injection and compaction of the sealing material; combined with the arrangement of the spring, telescopic rod and bracket, the roller can be buffered to prevent jamming.
