Technical Field
The invention relates to the technical field of building construction, in particular to a post-cast strip forming vertical mold for inter-column connection and a construction and use method thereof.
Background
With the increasing number of steel structures and steel-concrete composite structure buildings, the problems of corrosion resistance and fire resistance of the steel structures are more and more concerned by people.
The common steel structure adopts anticorrosive paint and fireproof paint for corrosion prevention and fire prevention, but the construction process is multiple, and the construction efficiency of the steel structure is influenced; and the material cost and the construction cost are high.
In the invention application CN201911373299.4 entitled fully clad steel-concrete composite member, the composite member comprises a web and a panel at the end of the web, the web is perpendicular to the panel, concrete is arranged between the web and the panel and at the side of the panel, and the concrete is clad on the composite member along the circumferential direction of the composite member. The device can realize the integration of corrosion resistance and fire resistance, realizes the age synchronization of the corrosion-resistant coating, the fire-resistant coating and the structure life, and reduces the cost.
When the completely-coated steel-concrete combined column is connected with the column, the coated steel structures of the completely-coated steel-concrete combined column and the column need to be welded firstly, concrete is poured at the steel structures after welding, and a vertical post-pouring belt is formed after the concrete is solidified. The post-cast strip needs to use a vertical mold, the traditional vertical mold is only a few simple wood boards, the wood boards are enclosed at the connecting area of the columns, then every two adjacent wood boards are clamped through steel bars so that the wood boards are wrapped at the enclosed area to form a mold body, and then grouting is injected into the mold body. The traditional vertical mold has unstable use effect, and the wood board is easy to loosen; although the grouting material can be selected from grouting materials with better flow state performance, the concrete form and the pouring effect of the grouting material in the closed area cannot be visually seen, and the judgment is not good.
Disclosure of Invention
The invention provides a post-cast strip forming vertical mold for inter-column connection, which is used as a concrete forming solidification template in an inter-column connection area and can be stably enclosed at the periphery of the inter-column connection area so as to improve the forming quality of the post-cast strip.

In the embodiment, the used grouting material is selected from IV-type cement-based grouting materials, the diameter of the thrown crushed stone is 5-25mm, the grouting material is poured into the enclosed area of the cladding formwork riser 1 from the grouting nozzle 10, and the card formwork riser unit plates 3 are gradually increased along with the pouring of the grouting material so as to increase the height of the cladding formwork riser 1 and lift the height of the grouting nozzle 10, so that the situation in the enclosed area of the cladding formwork riser 1 can be observed by construction technicians in the whole grouting and pouring process.
In addition, when the broken stones are thrown into the enclosed area of the cladding vertical template 1, the broken stones are guaranteed to be uniformly distributed, and when the cladding vertical template is used as a die body, the distribution positions of the broken stones can be well observed.
In addition, when the fixed connecting piece 2 is used for connecting the vertical mould unit plates 3 adjacent to each other in the horizontal direction, the connecting plate body 4 extending from the short side of each vertical mould unit plate 3 is kept outwards and positioned outside the enclosing area so as to ensure the complete shape of a post-cast strip and the attractive appearance of a surface layer, and the connecting plate body 4 is prevented from being sunk into concrete and being difficult to remove the vertical mould unit plates 3 in the later period.
When grouting material is poured into the enclosed area of the cladding vertical template 1, the sealing and plugging block 15 in the through hole 5 can be taken out to observe the flowing condition of the grouting material in the enclosed area, and then the through hole 5 is continuously sealed by the sealing and plugging block 15.
Where not mentioned above, all are applicable to the prior art.
Finally, it should be noted that: the above examples are only for illustrating the technical solutions of the present invention, and are not limited thereto. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
