Abstract
The utility model discloses an advanced water-stop steel plate structure for a post-pouring zone of underground construction, which is used for advanced water-stop for a concrete post-pouring zone of the underground construction. In the utility model, the post-pouring zone is directly provided with an advanced water-stop steel plate having a water-stop structure; the water-stop structure can be formed by upwards being bent from the two sides of the steel plate, or fully welding angle irons, or being provided with a water-stop bulge, or welding angle irons at the inner sides of the steel plate, or further embedding water-expandable rubber water-stop strips in the inner sides of the bent water-stop bulge. By adopting the advanced water-stop steel plate structure, after the weight of an underground building structure can balance a buoyant force, dewatering can be removed in advance, so that not only is the underground water resource saved and the construction cost lowered, but also the influence on the stability of surrounding buildings caused the dewatering can be reduced. The advanced water-stop steel plate structure has a novel structure and unique design, and has the advantages of reliable advanced water-stop effect, strong deformation adjustability, and the like; and in addition, when the advanced water-stop steel plate structure is used in an advanced water-stop project, an underlayer is not needed to be downwardly digged, the construction quantities are small, the construction is simple, the time limit for the project is saved, and the construction cost can be lowered.
Description
Technical field
The utility model belongs to concrete building structures underground engineering construction field, relates to the structure design of the leading steel plate for sealing water that uses in the leading sealing in a kind of underground construction ater-casting.
Background technology
The ater-casting is a kind of construction measure that is used to discharge shrinkage strain and stress that often uses in the concrete building structures construction, especially in the underground construction of highrise building, in order to regulate the sedimentation between the different discrepancy in elevation buildings, often needs to be provided with pouring after settlement.This ater-casting need (after generally topping out) just can be built after the structure sediment distortion is stable, and indwelling time is very long.During this, peripheral or inner precipitation well must constantly draw water, and guarantees that underground water is not from the ater-casting of keeping somewhere permeates the ground the chamber.Long-time groundwater abstraction, the one, engineering cost is very big, also can cause peripheral WATER LEVEL CHANGES in addition, causes neighboring buildings generation sedimentation and deformation.Therefore, at these positions, ater-casting leading water stop structure measure is set, for saving construction costs, safe construction is very necessary.
Also taked some measures in recent years in work progress, effect is unsatisfactory.As the way of advising among existing national standard " Technical code for water proof in underground engineering " GB50108, it is the external labeling type rubber fastening band that width 300～400mm is set in the bottom, shrinkage joint of ater-casting adjusting deformation place, and reserve the shrinkage joint of regulating deflection with pointing, sole plate need dig more than the 250mm down, and leading seal plate and sole plate be concreting simultaneously.In addition, also have in advance and dig about 300mm under the position, ater-casting, build about a 1500～2500mm of width in advance, both sides are provided with the steel concrete waterproof articulated slab of hydro-expansive rubber bar, and the articulated slab bottom is done waterproofing course in advance.
The Chinese patent of publication number CN201581510U (inventor Xiao Hua Feng, Liu Gan etc.) discloses the leading sealing of a kind of sole plate ater-casting.Its structure is distinguished with the suggestion way among " Technical code for water proof in underground engineering " GB50108 and is, change the external labeling type rubber fastening band of being located at the bottom, shrinkage joint into middle-set-type, and the packing material at position, clear and definite shrinkage joint is an extruded polystyrene board.
The Chinese patent of publication number CN201598645U (defend by inventor's flood loyalty; Chen Kerong; Liu Jianhua) the leading sealing of a kind of sole plate ater-casting is disclosed.Its structure is basic identical with the Chinese patent of publication number CN201581510U, and difference is that the packing material at position, clear and definite shrinkage joint is the wood fibre asphalt plank.
Above-mentioned technology all need be before blinding concrete construction, earth excavation under the position, ater-casting in advance just, if under the base plate exterior waterproof coating is arranged, and the construction waterproof layer of still needing, time-consuming; Use rubber fastening band, be easy in the construction damage, stagnant water effect is undesirable; In addition, because the shrinkage joint narrower in width of reserving, the adjusting deformation ability is limited, therefore, need improve above-mentioned technology.
The utility model content
The purpose of this utility model provides the leading steel plate for sealing water structure in a kind of ater-casting, be used for the leading sealing in underground construction ater-casting, can in the concrete structure sediment distortion, allow reserving the bigger distortion of position, ater-casting generation, and can prevent effectively that underground water from infiltrating the ater-casting.
To achieve these goals, the leading steel plate for sealing water in the underground construction ater-casting that the utility model provides is constructed, and is layed in the position of underground construction ater-casting, comprises horizontal direction steel plate that extends and the upwardly extending sealing projection of being located at steel plate length direction dual-side.Wherein,
Described sealing projection is directly become by bending on the edges of plate, or forms on steel plate with the angle steel full weld.
Be provided with inboard sealing projection in addition in the inboard of steel plate both sides sealing projection, inboard sealing projection is formed on steel plate by the angle steel full weld; Inboard sealing projection is one or multi-channel.
Fixture is established in inboard in the sealing projection, inlays water-swelling rubber water bar between outside sealing projection and inboard fixture.Described fixture is that horizontal welding is connected on angle steel or the reinforcing bar spaced apart and vertical welding with steel plate on the steel plate.
The edge of sealing projection outwards is bent to form horizontal sealing outer.Described sealing outer width is 50～100mm.
Described steel plate thickness 0.5～7.5mm, preferred 2～3mm; The width of steel plate adds 15～1000mm for the ater-casting width, preferably adds 400mm; The sealing height of projection is 10～100mm, is preferably 30～40mm.
Described surface of steel plate brushing rust preventive coating or epoxy enamelled coating.
Comprehensive, the utility model is provided with the leading steel plate for sealing water of water stop structure at the position of ater-casting, steel plate thickness 0.5～7.5mm, and the width of steel plate adds 15～1000mm for the ater-casting width, and there is water stop structure on both sides.This water stop structure can be by curved on the steel plate on both sides, also can the full weld angle steel, and the curved height or the height of welding angle steel are 10～100mm on the steel plate of both sides.The water stop structure at steel plate two ends only adopts when bending on the steel plate, can be one of a side, maybe will go up curved sealing projection rolls over outward, be formed with the sealing projection of outer, also can weld angle steel again in its inboard, formation is a side multiple tracks sealing bumps formation, can inlay or not inlay water-swelling rubber water bar in the water stopping trough that bends up; When inlaying water-swelling rubber water bar, need be at water-swelling rubber water bar opposite side spot welding fixture, when preventing concreting, water-swelling rubber water bar is shifted.For preventing that leading steel plate for sealing water corrosion damages between the operating period, the external coating rustproof paint or the epoxy paint of leading steel plate for sealing water.Leading steel plate for sealing water is laid along the ater-casting length direction, and the seam between two block plates adopts welding or bonding being connected.
