Abstract
The invention discloses a method for preassembling a large-sized vault. The method is characterized in that a preassembled terrace is paved; a bracket used for preassembling is built on the terrace; and single tiles of each part of the processed vault are arranged at corresponding positions of the bracket and adjacent single tiles are connected. The method brings convenience to the connection between the single tiles, solves the problem that the inner part of the vault has a welding trace due to the welding between the single tiles and a fixed support, and meets the design requirement under the condition that the welding is not permitted in the inner part of the vault.
Description
Technical field
The present invention relates to a kind of vault manufacturing technology, particularly a kind of large-scale vault is carried out pre-assembled method.
Background technology
Carry out in the pre-assembling process at large-scale vault, the mode that adopts the vault interior welds to support is usually assembled in advance.As ground moral formula hotblast stove, its vault mainly is made up of several parts such as segment, spherical zone and awl bands, and every part can be divided into some single watt again.Ground moral formula hotblast stove in the past allows the vault interior welds to support in design, by support and single watt of inwall between welding single watt is fixed on the corresponding position in a certain order.So, not only increase the assembling back and removed the operation of vault inner support, but also can on every single watt internal surface, leave the welding scar, destroyed the single watt of original smooth finish of inwall, having to, the internal surface to every single watt carries out grinding process before dispatching from the factory, and has wasted manpower and materials.The more important thing is, in case when the user has higher the requirement to the vault enclosure interior (not allowing welding as vault inside), this packaging technology can't satisfy the requirement in the design.
Summary of the invention
The object of the present invention is to provide a kind of large vault preassembling method, solution leaves the problem of welding scar because of welding the vault inside of being caused between single watt and the fixed support, so that under the situation that does not allow to weld in vault inside, still can meet design requirement, realize pre-assembling vault.
The object of the present invention is achieved like this, and a kind of large vault preassembling method is characterized in that: lay pre-assembly platform; On platform, build the carriage of pre-assembling usefulness; Single watt of the vault each several part that processes is placed on the corresponding position of carriage and and connects adjacent single watt.When building pre-assembling carriage, at first on pre-assembly platform, carrying out horizontal shape of the mouth as one speaks projection line according to the geometrical dimension of vault; Carry out blanking with the circumferential weld place that band is connected according to the geometrical dimension of vault at the vault band then; Be assembled into the carriage of being formed by some circular arc supporting beams with section bar at last.
Since the present invention the vault band be with the circumferential weld place be connected, geometrical dimension blanking according to vault, build the carriage that every band is assembled usefulness in advance with section bar, made things convenient for single watt with single watt between be connected, avoided leaving the problem of welding scar, also satisfied the design requirements that does not allow in vault inside under the welding situation simultaneously because of the vault inside that welding caused between single watt and the fixed support.

Embodiment
The present invention is an example with a kind of ground moral formula hotblast stove vault shown in Figure 1, and large vault preassembling method is described further.
As shown in Figure 1, ground moral formula hotblast stove vault by big segment 1, big spherical zone 2, awl be with 3, zona glomerulosa 4, bead lack 5 and form.Big segment 1 is made up of Habenaria dipionema Sohltr, and spherical zone 2 has three bands greatly, and every band is by ten pieces watts of compositions, awl is with 3 four bands are arranged, wherein two bands by Herba Chloranthi Henryi (Herba Choranthi seu Lysimachiae) forms, other two bands are made up of Herba Oxalidis Griffithii, zona glomerulosa 4 has a band, form by seven pieces watts, bead lacks 5 and forms by one piece watt.Vault is assembled in advance in factory, and vault inside did not allow welding when Design Requirement Drawing was assembled in advance, assembles in advance to take apart with single watt form after qualified to dispatch from the factory.It is 14mm that big segment 1, big spherical zone 2, zona glomerulosa 4, bead lack 5 thicknesss of slab, and it is 25mm that awl is with 3 thicknesss of slab, the internal surface alignment.
As shown in Figure 2, a kind of large vault preassembling method of the present invention may further comprise the steps:
The one, according to the design paper requirement single watt of vault each several part (big segment 1, big spherical zone 2, awl with 3, zona glomerulosa 4, bead lack 5) is carried out work in-process processing, be numbered according to the position at every single watt of place;
The 2nd, lay the pre-assembly platform of vault (order of first two steps is in no particular order);
The 3rd, on pre-assembly platform, carry out the horizontal shape of the mouth as one speaks projection line of vault according to the geometrical dimension of vault, at the circumferential weld place that vault band and band (big spherical zone 2, awl with 3, zona glomerulosa 4) are connected, geometrical dimension according to vault is carried out blanking, be assembled into the carriage of being formed by some circular arc supporting beams with section bar, the radian of the circular arc supporting beam vault internal surface pairing with it of carriage matches, and guarantees single watt internal surface alignment;
The 4th,, single watt of position is adjusted on the single watt of corresponding position that is placed in carriage by numbering, and adjacent single watt is connected by board-like regulator, make vault reach Design Requirement Drawing.
Shown in Fig. 3,4,5, board-like regulator is made up of the riser 6, web plate 8 and the punching pin 11 that are welded on vertical circumferential weld both sides on the single watt of outside surface.Riser 6 is provided with a through hole 7; Respectively there is an oblong aperture 10 that is slightly larger than riser 6 width at the two ends of web plate 8, are welded with cushion block 9 around each oblong aperture 10.During use, earlier riser 6 is welded on the corresponding position on vertical circumferential weld both sides, then web plate 8 is enclosed within on the riser 6, order of accuarcy according to single watt of position, punching pin 11 is aimed at the hole 7 of riser 6, impact punching pin 11 with hand hammer and adjust single watt position, simultaneously adjacent single watt is coupled together, make vault reach Design Requirement Drawing.
In addition, the hoop adjustment is indulged in single watt of position also can be cooperated with chock and adjust by " L " plate that falls that is welded on the single watt of outside surface, and connect by angle steel and the fitted bolt that is welded on single watt of outside surface upper limb, make vault reach Design Requirement Drawing.
