Abstract
A seamless connection construction method for an oversized-area ultrahigh-precision one-step forming floor is characterized in that the edges of the periphery of a first-pouring area are surrounded by angle steel, a vertical steel wire mesh is arranged at the joint of the first-pouring area and a later-pouring area, the steel wire mesh is fixed on the outer side surface of the angle steel, and two adjacent steel wire meshes are tightly connected; then concrete pouring is carried out. The invention avoids a series of quality problems of water seepage, water leakage and the like caused by construction joints at the joint in the later period.
Description
Technical Field
The invention relates to the technical field of construction engineering construction, and particularly belongs to a seamless connection construction technology for an ultra-large-area ultra-high-precision one-step forming terrace.
Background
In the construction process of the once-formed terrace with the ultra-large area and the ultra-high precision, the terrace is generally divided into regions, then concrete is poured according to the regions, a construction joint is formed between the first-poured concrete and the second-poured concrete, concrete aggregate at the construction joint is concentrated, the concrete is loose, the connection of old concrete and new concrete is obvious, and the conditions of water seepage and water leakage are easy to occur along the joint. Not only the beauty is affected, but also the maintenance and the reworking can be carried out due to the quality problems of water seepage, water leakage and the like even in the later period.
Disclosure of Invention
The invention aims to solve the technical problem of providing a seamless connection construction method for an oversized-area ultrahigh-precision one-step forming terrace, so that concrete poured in sequence is tightly combined to form an integral structure, and the problems of a series of water seepage and water leakage caused by construction joints at concrete joint parts are solved.
In order to solve the technical problems, the invention adopts the technical scheme that the seamless connection construction method for the super-large-area and ultrahigh-precision one-step forming terrace is characterized in that the periphery of a first pouring area is surrounded by angle steel, a vertical steel wire mesh is arranged at the joint of the first pouring area and a later pouring area, the steel wire mesh is fixed on the outer side of the angle steel, and two adjacent steel wire meshes are tightly connected; then concrete pouring is carried out.
The angle steel is fixed on the steel bar truss of the terrace through welding.
And (4) binding and fixing the angle steel and the steel wire mesh together.
The angle steels at two adjacent edges are connected by welding.
The aperture of the steel wire mesh is less than or equal to 2 mm.
The steel wire meshes are connected in an overlapping mode, and the overlapping length is larger than or equal to 100 mm.
According to the seamless connection construction technology for the oversized-area ultrahigh-precision one-step molding terrace, the angle steel is installed around the concrete pouring area and is welded and fixed with the steel bar truss, then the steel wire mesh is laid along the angle steel, the steel wire mesh is bound and fixed with the angle steel, and then concrete pouring is carried out. The invention can effectively connect the pre-cast concrete and the post-cast concrete into a whole through the steel wire mesh in the construction process of the super-large-area and super-high-precision one-step molding terrace, and avoids a series of quality problems such as water seepage and water leakage caused by construction joints at the joint.

FIG. 2 is a schematic cross-sectional view of the present invention.
Detailed Description
The seamless connection construction technology for the super-large-area and ultra-high-precision one-step molding terrace comprises the following construction processes: firstly, determining a concrete first-pouring area, then arranging angle steel 1 at the periphery of the concrete first-pouring area, wherein the size of the angle steel is 30mm multiplied by 3mm, and fixedly connecting the angle steel with a steel bar truss 3 of a terrace in a welding mode. The outer side surface of the angle steel is positioned on one side of the first pouring area. And the adjacent two angle steels are fixed at the intersection by welding.
By the operation, the joint of the pre-cast area and the post-cast area can be tightly combined due to the existence of the steel wire mesh, and the joint is connected into a whole, so that the aim of seamless connection is fulfilled. And a series of quality problems such as water seepage and water leakage caused by construction joints at the joint in the later period are avoided.
