Abstract
The invention relates to a sealing structure for gaps between a steel plate and concrete in pouring-type steel bonding construction, and the sealing structure can be used for solving the problems that the existing gap sealing glue is wasted seriously, the construction period is long, the effective bonding area of the steel plate is small, the dense degree for pouring of pouring-type steel bonding glue is very difficult to control, and the detection accuracy on the effective bonding area of the steel plate is low. The sealing structure is provided with the steel plate, a concrete plate is arranged on the steel plate, a transparent sealing strip with the L-shaped section is bonded on the side surface of the edge of the steel plate, the top end of the sealing strip is bonded with the concrete plate, and a cavity the area of which is larger than that of the steel plate is formed between the steel plate and the concrete plate and is filled with structural glue. According to the sealing structure, the consumption and waste of liquid glue are less; the sealing construction time is shortened by virtue of colloid with high curing speed; and the pouring condition of the glue liquid in the gap between the steel plate and the concrete can be watched in a pouring construction project, thereby improving the controllability on the pouring of the structural glue.
Description
Technical field
the present invention relates to the strengthening construction field of highway bridge, be specifically related to a kind of hermetically-sealed construction that pours into steel bonding construction light plate and concrete gap.
Background technology
Cohesive-Steeled Reinforcement Technique is to using structure glue as bonding adhesive, and steel plate or the section bar of reinforcing use are bonded on reinforced concrete structure securely, makes the common stressed reinforcing technique of steel plate or section bar and reinforced concrete structure.This technology has simply, fast, does not affect construction profile and usage space, and the construction period is short, and therefore the advantage such as can not get angry during construction is used widely in bridge strengthening field.
Steel-bonded reinforcement construction technology is divided into being coated with scrapes method steel bonding and perfusion steel bonding: being coated with and scraping method steel bonding is to scrape paste structure glue at strengthening steel slab and concrete surface painting, before structure glue sclerosis, steel plate and concrete conglutination is fixed; Perfusion steel bonding is first strengthening steel slab to be fixed on concrete, by after steel plate and concrete clearance seal, then to pressure injection flow-like structure glue in steel plate and concrete gap.Perfusion steel bonding working procedure is more, still, when strengthening steel slab thickness surpasses in 5mm or the larger situation of monolithic strengthening steel slab area, must adopt perfusion steel bonding guarantee steel bonding effect.
Perfusion steel bonding construction need to seal steel plate and concrete gap, and the conventional method adopting is to take and allocate sealing compound in recommending to join glue ratio, then uses spatula that steel plate periphery gap, expansion bolt and adhesive pouring nozzle gap is around sealed with sealing compound.There is following problem in conventional steel plate and concrete clearance seal method: (1) adopts in the construction of spatula blade coating joint seal glue, and the loss of joint seal glue is larger, wastes more serious; (2) the joint seal adhesive curing time longer, extended the seal construction time, increased the construction period; (3), while adopting joint seal rubber seal to close steel plate periphery gap, part joint seal glue enters steel plate and concrete gap, has reduced the effective bonding area of steel plate; (4), owing to adopting joint seal rubber seal to close steel plate and concrete gap, in perfusion steel bonding work progress, cannot observe the closely knit situation of perfusion of the inner pouring type steel bonding of steel plate and concrete gap glue; (5) after perfusion steel bonding has been constructed, the mode that need to adopt hand hammer to knock is checked effective bonding area of steel plate, method of inspection trouble, and be difficult to accurately effective bonding area of estimation steel plate.
Summary of the invention
The object of this invention is to provide a kind of hermetically-sealed construction that pours into steel bonding construction light plate and concrete gap, to overcome, the waste of prior art joint seal glue is serious, the construction period is long, the effective bonding area of steel plate is little, the closely knit control difficulty of the perfusion of pouring type steel bonding glue large and the low defect of effective bonding area check degree of accuracy of steel plate.
The technical solution adopted in the present invention is:
The hermetically-sealed construction in perfusion steel bonding construction light plate and concrete gap, is provided with steel plate and concrete structure, it is characterized in that:
Described side, edges of plate by the 502 gluing cross sections that are connected to for the transparent sealing bar of " L " shape, weather strip top is mutually bonding with concrete structure by 502 glue, between steel plate and concrete structure, form the cavity that area is greater than steel plate, interstitital texture glue in cavity.
Between the weather strip of described " L " shape, by AB is gluing, connect.
The end face of two bossings of the weather strip of described " L " shape is inclined-plane.
The present invention has the following advantages:
1, the present invention adopts 502 glue and two kinds of colloid sealing off gap of AB glue and space, and consumption glue quantity is few, and waste is few.
2, the present invention adopts the fast colloid of curing rate, has reduced the seal construction time, has shortened the construction period.
3, the present invention adopts L-type transparent sealing bar, can observe glue in steel plate and concrete gap perfusion situation in pouring construction process, has improved the controllability of structure glue perfusion.
4, the present invention adopts L-type transparent sealing bar, and in structure glue filling process, it is inner that structure glue flows into L-type transparent sealing bar, significantly improves effective bonding area of steel plate.
5, the present invention adopts L-type transparent sealing bar, and the rear removal L-type transparent sealing bar of having constructed, can judge structure glue perfusion effect according to the full degree of steel plate marginal texture colloid, has improved the testability of perfusion steel bonding construction effect.
