Detailed Description
The technical scheme of the method for improving the compactness of the fabricated concrete grouting connection node according to the invention will be further described in detail with reference to the following embodiments.
The stepping furnace forming refractory brick of the embodiment shown in fig. 1-3 comprises a prefabricated brick 2 and a base plate 1, wherein a connecting piece is arranged on the base plate 1, and a plurality of connecting through holes 4 are arranged on the prefabricated brick 2.
During the installation, directly connect prefabricated brick 2 through connect the via hole 4 and connecting piece, will be able to bear or endure firebrick and install 3 one sides at heat-resisting steel, when the release of nai firebrick, breakage, directly take off resistant firebrick, install new resistant firebrick, great reduction step furnace prosthetic time, can furthest shorten because of resistant firebrick release, the broken time limit that delays of breakage, the broken prefabricated brick 2 that gets off of changing, but carry out restoration back repeatedly usable.
In this embodiment, the connecting member includes a plurality of bolts 5 and nuts 6, the bolts 5 and the nuts 6 are all welded to the chassis 1, and each bolt 5 is inserted into one of the connecting through holes 4 and detachably connected to the prefabricated brick 2 through the nut 6; connecting through hole 4 includes wide hole portion 402 and narrow hole portion 403 from last down in proper order, the internal diameter of narrow hole portion 403 is slightly greater than the diameter of bolt 5, the internal diameter of wide hole portion 402 is slightly greater than the external diameter of nut 6, the length of bolt 5 is greater than the degree of depth of narrow hole portion 403, the length of bolt 5 is less than connecting through hole 4's degree of depth.
The installation principle is as follows: aligning the connecting through hole 4 of the prefabricated brick 2 with the bolt 5, and inserting the prefabricated brick 2 onto the bolt 5, as shown in fig. 2, the length of the bolt 5 is greater than the depth of the narrow hole part 403, but the length of the bolt 5 is less than the depth of the connecting through hole 4, so that the upper part of the bolt 5 extends to the wide hole part 402, at this time, the nut 6 is screwed onto the bolt 5 of the wide hole part 402, and the nut 6 is screwed onto the bottom of the wide hole part 402, completing the installation; when the prefabricated brick 2 is loosened and broken, the nut 6 is screwed out, the prefabricated brick 2 is taken out, and a new prefabricated brick 2 is replaced, so that the operation is convenient, the workload is low, the repair time is greatly saved, and the delay period caused by repairing the stepping furnace can be shortened to the greatest extent.
In this embodiment, a nut washer 7 is provided between the bottom of the wide hole 402 and the nut 6.
And a nut gasket 7 is added, so that the fixation is more stable.
A method of using a walking beam furnace to form refractory bricks, in which method a walking beam furnace of the above kind is used to form refractory bricks, the method comprising the steps of:
the method comprises the following steps: installing a chassis 1 welded with bolts 5 beside the heat-resistant steel 3;
step two: aligning the narrow hole part 403 of the connecting through hole 4 with the bolt 5 and inserting the prefabricated tile 2 on the bolt 5, since the length of the bolt 5 is greater than the depth of the narrow hole part 403, but the length of the bolt 5 is less than the depth of the connecting through hole 4, the upper part of the bolt 5 extends to the wide hole part 402;
step four: screwing the nut washer 7 and the nut 6 onto the bolt 5 positioned in the wide hole part 402 in sequence, and screwing the nut washer 7 and the nut 6 into the bottom of the wide hole part 402 in sequence;
