Description

Technical Field

[0001] The utility model relates to the technical field of the installation of embedded iron parts in walls, and more specifically, to a shear wall with split embedded iron parts in a part where steel bars are densely arranged. Background Technique

[0002] A shear wall is also called a wind-resistant wall, a seismic wall or a structural wall. It is a wall in a building or structure that mainly bears the horizontal load and vertical load (gravity) caused by wind load or seismic action, and prevents the structure from being damaged by shear (shearing). It is also called a seismic wall and is generally made of reinforced concrete.

[0003] In the design of drawings at the top of the shear wall concrete structure and other parts, there are generally situations where the wall steel bars and the concealed beam steel bars are densely arranged and staggered. When installing long embedded iron parts in such parts, due to the too dense arrangement of steel bars, the anchor steel bars of the embedded iron parts collide with the structural steel bars when being lowered and cannot be installed. The construction difficulty is large and the installation accuracy is poor. However, this long embedded part is used for installing equipment later, and high requirements are placed on its flatness. It is difficult to control the flatness of the above-mentioned long embedded iron part. Summary of the Invention

[0004] In view of this, the utility model proposes a shear wall with split embedded iron parts in a part where steel bars are densely arranged, including:

[0005] A shear wall body, which includes horizontal steel bars, vertical steel bars and stirrups. The horizontal steel bars are vertically connected to form a wall frame, and the stirrups are arranged in the shear wall body to obliquely pull and fix the vertical steel bars and the horizontal steel bars;

[0006] A split embedded iron part, which includes an embedded iron part and anchor steel bars. The embedded iron part is arranged at the part where the steel bars are densely arranged on the shear wall body, and a plurality of reserved holes are arranged on the embedded iron part. The anchor steel bars pass through the reserved holes and are inserted into the shear wall body.

[0007] Preferably, the thickness of the embedded iron part ≥ 20 mm and the length ≥ 3 m.

[0008] Preferably, the embedded iron part is fixed to the shear wall body through the arranged positioning steel bars.

[0009] Preferably, the positioning steel bars are welded at the four corners of the pre-installation position of the embedded iron part.

[0010] Preferably, the specification of the embedded steel bar is φ14 with a length of 350 mm.

[0011] Preferably, the embedded iron part is welded and connected to the positioning steel bars.

[0012] Preferably, the elevation, flatness and plane position of the embedded iron part meet the construction requirements.

[0013] Preferably, the outer surface of the anchoring steel bars is thread-rolled.

[0014] Preferably, a mating nut corresponding to the reserved hole is provided on one side of the embedded part close to the shear wall body, and the specification of the mating nut matches that of the anchoring steel bars.

[0015] Preferably, the anchoring steel bars are welded to the embedded part by plug welding at the position of the reserved hole.

[0016] The shear wall provided by the present utility model with a split embedded part in the area where steel bars are densely arranged has the following advantages: welding nuts at the bottom of the reserved hole of the embedded part can prevent the anchoring steel bars from falling into the shear wall and being unable to be taken out, which can enhance the anti-pulling performance of the embedded part and facilitate the adjustment of the flatness of the embedded part; the combined installation of the shear wall is convenient, shortening the construction period. It can be prefabricated, and after passing the acceptance and being put into use, it is transported to the construction site, and the installation is fast and simple, reducing the construction period, saving time and effort, and facilitating the cleaning of materials; the welding quality, installation accuracy and construction safety are guaranteed, the construction efficiency is improved, and thus the construction period is shortened.

[0032] A construction method for a shear wall with split embedded iron parts at a densely reinforced area:

[0033] (1) Welding of positioning steel bars: After the steel bars and formwork in the densely-reinforced areas such as the shear wall body have been accepted, weld 350mm long φ14 positioning steel bars at the four diagonal positions of the embedded iron parts designed in the drawings;

[0034] (2) Making embedded steel plates, that is, making embedded iron parts: the embedded steel plates are made according to the designed dimensions and reserved holes for anchoring steel bars are cut to prevent some anchoring steel bars from being unable to penetrate into the designed positions in the later stage. The number of reserved holes is appropriately increased to ensure that the length of the anchoring steel bars in the later stage is sufficient. The bottom of the reserved holes of the reserved steel plates is welded with matching nuts of the same specifications as the anchoring steel bars;

[0035] (3) Installation of embedded steel plates: hoisting and welding of embedded steel plates and positioning steel bars, and checking elevation, flatness and plane position, etc.;

[0036] (4) Production of anchor steel bars: The anchor steel bars are threaded with full-length threads by professional threading machines and matched with nuts of the same specifications;

[0037] (5) Installation of anchor steel bars: Since the embedded iron parts are located at the top of the shear wall and the formwork on both sides of the shear wall has been completed, there is not enough space for the installation of anchor steel bars. Therefore, the anchor steel bars are screwed down through the nuts in the reserved holes on the embedded steel plates. If part of the anchor steel bars hit the structural steel bars of the shear wall or the hidden beam during the screwing process, the screwing can be stopped.

[0038] (6) Welding of embedded steel plates and anchor steel bars: After the anchor steel bars are inserted into the designed position, the welding operation is carried out by perforation plug welding.

[0039] The utility model discloses a shear wall with split embedded iron parts in a densely distributed steel bar area, which has the following beneficial technical effects: the welded nuts at the bottom of the reserved holes of the embedded iron parts can prevent the anchor steel bars from falling into the shear wall and being unable to be taken out, can enhance the pull-out resistance of the embedded parts, and is convenient for adjusting the flatness of the embedded iron parts; the shear wall assembly is convenient to install, shortens the construction period, can be processed in advance, and can be transported to the construction site after acceptance and use, which is quick and easy to install, shortens the construction period, saves time and effort, and is convenient for material cleaning; ensures welding quality, installation accuracy and construction safety, improves construction efficiency, and thus shortens the construction period.
