Description

Technical Field

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

[0002] Currently, precast reinforced concrete walls mainly consist of shear walls for above-ground structures. The node connection forms of shear wall structures for basement exterior walls mainly include the following three types: reinforced sleeve grouting connection form, reinforced mortar anchor lap connection form, and double-sided composite shear wall connection form. The first two are shear wall connection forms specified in the Technical Standard for Assembled Concrete Structures GBT51231 - 2016, and the third is a newly developed precast shear wall connection form by various precast concrete processing plants in the past two years. The connection methods between these three types of shear walls are all carried out through steel bar forms. Among them, the first two are processed by grouting after sleeve and mortar anchor; the third is connected by inserting steel bars into the middle of the upper and lower laminated shear walls, and then connected by pouring fine stone concrete. The steel bar connection processing methods of these three precast shear wall structures all have certain difficulties in node connection and concealed acceptance, and it is easy to have defects in quality control. For example, the grouting of the first two is not dense, and the fine stone concrete poured in the third is not dense, etc., resulting in defects in the connection between the upper and lower shear walls.

[0003] Therefore, the known connection methods for two shear walls have the above-mentioned various inconveniences and problems.

[0004] The purpose of the present invention is to propose a construction method for a precast reinforced concrete wall with a safe and reliable embedded steel plate bolt 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 plate bolt connection form, characterized by including the following steps:

[0007] a. Fabricate the upper embedded bolt connection steel plate of the precast reinforced concrete wall, including the following steps:

[0008] (1) Take one piece of the first type of steel plate, 2200mm×1100mm×12mm, Q235 steel plate, and divide it into two parts along the short direction of the steel plate: the upper part is 2200mmX100mm, and the lower part is 2200mmX1000mm. In the part of the precast wall where the steel plate is connected by embedded bolts at the upper part, square holes of 32mm×66mm, 40mm×66mm, ……, 40mm×66mm, 32mm×66mm are opened at intervals of 57mm, 93mm, 100mm, 100mm, ……, 93mm, 57mm in sequence along the long direction for passing the tie bars. At the same time, double bolt holes of M12, M16, ……, M16, M12 are opened in the gaps between the square holes; in the part buried in the precast wall at the lower part, square holes of 140mm×140mm are opened every 200mm at 30mm from the edges of the long direction and the short direction, and the function is to pass the wall reinforcement bars and the floor slab reinforcement bars;

[0009] Use the same method to make another piece of 2200mm×1100mm×12mm, Q235 steel plate.

[0010] (2) Adopt 300mm long grade III steel Φ12mm reinforcement bars with a spacing of 400mm×400mm, and align and weld the two made 2200mm×1100mm×12mm, Q235 steel plates to form a steel plate frame composed of two steel plates, and the spacing between the two steel plates is 300mm;

[0011] b. Make the lower part of the precast reinforced concrete wall with embedded bolt connection steel plate, including the following steps:

[0012] (1) Take one piece of the second type of steel plate, 2200mm×900mm×12mm, Q235 steel plate, and divide it into two parts along the short direction of the steel plate: the upper part is 2200mmX800mm, and the lower part is 2200mmX100mm. In the part buried in the precast wall at the upper part, square holes of 140mm×140mm are opened every 200mm at 30mm from the edges of the long direction and the short direction, and the function is to connect the tie bars. In the part where the upper and lower precast walls are connected at the lower part, square holes of 32mm×66mm, 40mm×66mm, ……, 40mm×66mm, 32mm×66mm are opened at intervals of 57mm, 93mm, 100mm, 100mm, ……, 93mm, 57mm in sequence along the long direction for passing the wall reinforcement bars. At the same time, bolt holes of M12, M16, ……, M16, M12 are opened in the gaps between the square holes;

[0013] Use the same operation to make another piece of 2200mm×1100mm×12mm, Q235 steel plate;

[0014] (2) Adopt grade 3 steel bars Φ12mm with a length of 288mm, spaced at 400mm×400mm. Align and weld two fabricated Q235 steel plates of 2200mm×1100mm×12mm to form a steel plate frame composed of two steel plates, with a spacing of 300mm between the two steel plates.

[0015] c. Fabricate a precast reinforced concrete wall with an embedded steel plate bolt connection form, including the following steps:

[0023] After the concrete of the cast-in-place part of the laminated slab reaches the required strength, align the M12 and M16 10.9-grade bearing-type high-strength bolt holes at the lower part of the precast reinforced concrete wall with bolt connection form of the upper steel plate with the M12 and M16 10.9-grade bearing-type high-strength bolt holes at the upper part of the precast reinforced concrete wall with bolt connection form of the lower steel plate, install the M12 and M16 high-strength bolt connection pairs, and at the same time install the structural steel bars of grade III steel Φ10 and stirrups of grade III steel Φ10@100 for the post-cast part of the precast wall.

[0024] After closing the post-cast part of the precast wall with formwork, use C35 fine aggregate concrete or C60 grouting material with a strength grade one higher than that of the precast wall. After reaching the required strength, remove the formwork for curing.

[0096] The present invention has substantial features and remarkable technical progress. The construction method of the precast reinforced concrete wall with a steel plate bolt connection form of the present invention is different from the steel bar connection methods of the standard steel bar sleeve grouting connection form, the steel bar slurry anchor lap joint connection form, and the double-sided composite shear wall connection form.

Those skilled in the relevant technical fields can also make various transformations or changes without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and should be defined by each claim.

(2) After the concrete of the cast-in-place part (4) of the composite slab reaches the strength, align the M12 and M16 10.9-grade bearing-type high-strength bolt holes at the lower part of the upper precast reinforced concrete wall with steel plate bolt connection form (1) with the M12 and M16 10.9-grade bearing-type high-strength bolt holes at the upper part of the lower precast reinforced concrete wall with steel plate bolt connection form, and install the M12 and M16 high-strength bolt connection pairs (8, 15). At the same time, install the structural steel bars of grade III steel Φ10 and the tie bars of grade III steel Φ10@100 (9) for the post-cast part of the precast wall. (3) After closing the post-cast part of the precast wall with formwork, use grout (5) with a strength grade one higher than that of the precast wall. After reaching the strength, remove the formwork and carry out curing.
