Description

Technical Field

[0001] The present invention relates to a reinforced concrete shear wall, and more specifically, to a construction method for a precast reinforced concrete shear wall with an embedded steel skeleton welded connection form. Background Art

[0002] Currently, precast reinforced concrete shear walls mainly focus on above-ground structural shear walls. The node connection forms of basement exterior wall shear wall structures mainly include the following three types: steel bar sleeve grouting connection form, steel bar slurry anchor lap connection form, and double-sided composite shear wall connection form. The first two are shear wall connection forms in the Technical Standard for Assembled Concrete Structures GBT51231-2016, and the third is a new precast reinforced concrete shear wall connection form developed by various precast concrete processing plants in the past two years. The connection methods between these three shear walls are all connected through steel bar forms. Among them, the first two are processed by grouting after sleeve and slurry anchor; the third is connected by inserting steel bars into the middle of the upper and lower composite shear walls, and then connected by pouring fine stone concrete. The steel bar connection treatment methods of these three precast reinforced concrete shear wall construction methods all have certain difficulties in node connection and concealed acceptance, and quality control is prone to defects. There are problems such as incomplete grouting in the first two, and incomplete pouring of fine stone concrete in the third, resulting in defects in the connection between the upper and lower shear walls.

[0003] Therefore, the known reinforced concrete shear wall structural methods have the above-mentioned various inconveniences and problems. Summary of the Invention

[0004] The purpose of the present invention is to propose a safe and reliable construction method for a precast reinforced concrete shear wall with an embedded steel skeleton welded connection form.

[0005] To achieve the above purpose, the technical solution of the present invention is:

[0006] A construction method for a precast reinforced concrete wall with an embedded steel skeleton welded connection form, characterized by including the following steps:

[0007] a. Fabricate the upper embedded welded connection steel skeleton of the precast reinforced concrete shear wall, including:

[0008] (1). Prepare a number of rectangular first steel plates. Each first steel plate is provided with round holes with a diameter of 40 mm in the middle of both ends in the length direction by 50 mm. The function of the round holes is to pass steel tie bars;

[0009] (2). Prepare a number of long-strip second steel plates. The top of each second steel plate is provided with a small round hole with a diameter of Φ20 mm. Two large round holes with a diameter of Φ40 mm are provided at intervals up and down in the middle of the second steel plate. An elliptical hole is provided below the small round hole. The elliptical hole is 102 mm × 20 mm for passing tie bars;

[0010] (3). Prepare several rectangular third steel plates. At the middle part of both ends of the third steel plate in the length direction, there are large round holes with a diameter of 40 mm. The function of the large round holes is to pass through steel tie bars.

[0011] (4). According to the widths of the two steel skeletons arranged in the designed concrete wall, prepare several rectangular fourth steel plates for fixed connection between the two steel skeletons.

[0012] (5). Fabricate the first steel skeleton: Vertically arrange the long strip-shaped second steel plates from one side to the other side, with a spacing of 300 mm between adjacent second steel plates. The bottom end of the second steel plate is perpendicularly welded and fixed to the horizontally arranged third steel plate, with a weld height of 10 mm. The middle part of the second steel plate is perpendicularly welded and fixed to the horizontally arranged first steel plate, so that the first steel plate is set as two horizontally arranged transverse steel plates with intervals. Fabricate the second steel skeleton in the same way, and then arrange the two steel skeletons correspondingly. At the middle part of the two steel skeletons, weld and connect them with several fourth steel plates. The welding connection points of the fourth steel plates are set at the positions of the transverse steel plates, thus fabricating the upper lattice steel skeleton of the precast reinforced concrete shear wall.

[0013] b. Fabricate the lower embedded welded connection steel skeleton of the precast reinforced concrete shear wall, including:

[0014] Fabricate the lower embedded welded connection steel skeleton of the precast reinforced concrete shear wall. The fabrication method of the lower embedded welded connection steel skeleton is exactly the same as that of fabricating the upper embedded welded connection steel skeleton of the precast reinforced concrete shear wall in step a. The difference is that no oval holes are provided, thus fabricating the lower embedded welded connection steel skeleton of the precast reinforced concrete shear wall. The small round holes of the upper embedded welded connection steel skeleton are at the top end of the steel skeleton, while the small round holes of the lower embedded welded connection steel skeleton are at the bottom end of the steel skeleton.

In the reinforcement encryption area, grade III steel Φ12@100 is used, single-layer and two-way. Make the second steel mesh cooperate with the first steel mesh and clamp and install them on both sides of the precast reinforced concrete shear wall.

[0019] (4)Install the tie bars, which are arranged in a quincunx pattern between the embedded steel members welded to connect the steel skeleton at the upper part of the precast reinforced concrete shear wall and the embedded steel members welded to connect the steel skeleton at the lower part of the precast reinforced concrete shear wall.

After reaching the strength, remove the formwork and hoist it to the finished product storage area.

[0021] d. Installation of the finished precast reinforced concrete shear walls with the embedded steel member welded connection form for the upper and lower sheets:

[0022] (1)After laying the precast floor slab at both ends of the lower precast reinforced concrete shear wall, lay the upper steel bars of the precast floor slab, then pour the C30 concrete for the cast-in-place part of the composite slab and perform curing.

[0023] (2)After the concrete for the cast-in-place part of the composite slab reaches the strength, align and weld the positions of the welded steel members at the lower part of the upper precast reinforced concrete shear wall with the embedded steel member welded connection form and the positions of the welded steel members at the upper part of the lower precast reinforced concrete shear wall with the embedded steel member welded connection form. The weld seam is 10 mm. At the same time, install the structural steel bars of grade III steel Φ12 for the post-cast part of the shear wall and the tie bars of grade III steel Φ12@200.

[0024] (3)After closing the post-cast part of the shear wall with formwork, use C40 fine aggregate concrete or C60 grout with a strength grade one higher than that of the shear wall. After reaching the strength, remove the formwork and perform curing.

[0025] (4)Repeat the above steps for the connection and installation of the upper precast reinforced concrete shear wall with the embedded steel member welded connection form and the lower finished precast reinforced concrete shear wall with the embedded steel member welded connection form.
