Description

A prefabricated hollow slab shear wall structure

technical field

The utility model relates to an assembled hollow plate shear wall structure, which belongs to the field of building industrialization.

Background technique

In the existing prefabricated shear wall structure system, the prefabricated shear walls are all constructed in the form of layered prefabrication (according to the floor height) and on-site assembly. The vertical steel bars between the upper and lower prefabricated shear walls are connected in the form of grouting sleeves, bellows grout anchors, and restraint grout anchors. In the shear wall structure of these three connection forms, the wall panels are all solid wall panels, and the wall panels are heavy and difficult to lift.

"Code for Design of Prefabricated Shear Wall Structure" DB11/1003-2013 (Beijing local standard) stipulates that in the 7th degree area, the prefabricated circular hole plate shear wall system can be used when the building height is less than 60m. In this system, the circular hole plate shear wall is prefabricated in layers (according to the floor height), and the vertical connection steel bars of the wall panels are arranged in the circular holes, and the upper and lower layers of steel bars are lapped and connected. The round hole panels are spliced according to a certain width modulus, and there are many vertical joints on the wall panels, and there are a large number of outer formworks during construction, which is inconvenient for on-site construction.

In addition, in the existing hollow wall panel structure system, the pre-embedded line pipes need to be arranged vertically along the circular hole passage, and when the line pipes are laid horizontally, on-site slotting is required, resulting in low construction efficiency.

The concealed beam 3 is provided with beam longitudinal ribs 4; the pre-embedded wall panel connector 23 and the cast-in-place node connector 22 are both provided with cast-in-place node longitudinal ribs 24 . As shown in FIGS. 7 and 8 , the hidden beam 3 is provided with a pre-embedded line pipe 16 , a wire box 19 or a water pipe 17 along its length direction.

Preferably, each prefabricated shear wall is assembled from 3-6 hollow wall panels, and at least one prefabricated shear wall is provided with a window installation area 12 in the middle. In this embodiment, the shear wall without windows is spliced from bottom to top by 3 hollow wall panels 13, 14, 15, and the shear wall with windows is composed of 4 hollow wall panels 1, 2, 10, 11 stitched together. As shown in Figures 1 and 6, a single-sided shear wall with a window installation area 12 includes a hollow wall panel 1 at the bottom, a hollow wall panel 11 at the top, and a hollow wall panel at the bottom. Two middle hollow wall panels 2,10 between the wall panel 1 and the uppermost hollow wall panel 11; two middle hollow wall panels 2,10, one lowermost hollow wall panel 1, and one uppermost hollow wall panel The window installation area 12 is enclosed between the wall panels 11 .

The pumping hole 18 reserved by the wallboard is a square hole or a round hole.

During the construction of water and electricity pipelines, as shown in Figure 7, between two socket points on the same circuit in the same component, the construction process when connecting the pipelines is: the installation of the lower hollow wall panel is completed → opening → installation of the wire box → laying the pipeline (After laying the hidden beam reinforcement, lay the wire pipe in the joint of the hollow wall panel) → butt joint of the wire and conduit box → install the upper hollow wall panel. Where h is the height of the wire box from the ground. As shown in Figure 8, the horizontal pipes of the water supply pipes can be laid using the horizontal joints of the hollow wall panels. The specific construction process is: the installation of the lower hollow wall panels is completed → the laying of water pipes (after the hidden beam reinforcement is laid, the water pipes are laid in the joints of the hollow wall panels) → the installation of the upper hollow wall panels.

As shown in Figure 1, the utility model adopts a variety of connection forms different from the traditional structural system:

First of all, the prefabricated part of the shear wall adopts an evacuated design, and the evacuated part can be a round hole or a square hole. The vertical connecting steel bars of the shear wall are arranged in the pumping holes, and the vertical steel bars are lapped in the form of binding. After the shear wall is evacuated, the weight of the wall panel can be greatly reduced, and the prefabricated components are easy to lift, as shown in Figure 2.

Secondly, the hollow wall panels of the prefabricated shear walls are provided with two horizontal separation joints within the height range of a floor, and the wall panels are divided into three sections along the height, which are window sill height H1, window height H2, and window beam height H3, as shown in the figure 3. After the wall panels are separated along the height, a structural concealed beam is made through the joints of the wall panels. The concealed beam can ensure the vertical integrity of the wall panels and can solve the problem of water leakage at the horizontal joints of the wall panels. After separation, the height of the wall panel is reduced and the quality is reduced, which is convenient for mass production in the factory. The vertical joint position of the prefabricated wall panel is determined according to the bay and depth of the building, and the entire width is used to reduce the number of vertical joints on site.

Overhanging thin walls are set at the joints of prefabricated shear wall hollow wall panels and vertical cast-in-place nodes. This thin-walled structure can be used as the outer formwork when the joint concrete is poured and the formwork is set up on site. Simplify the on-site formwork process, speed up the on-site construction progress, and the project can achieve the effect of no external frame as a whole. As shown in Figure 4 and Figure 5.

As shown in Figure 5, at the junction position between the prefabricated shear wall hollow wall panel and the floor, flanging is provided along the outer side, and the flanging height is the same as the thickness of the floor slab. This structural design method can solve the problem of formwork on the outside of the floor when the floor is poured, simplify the on-site formwork process, and speed up the on-site construction progress. At the same time, it can ensure that the appearance of the wall is smooth after the floor slab is poured, and the construction quality of on-site pouring can be improved.

The construction method of the above-mentioned prefabricated hollow slab shear wall structure is as follows:

S1, arranging vertical connectors to form vertical connecting ribs of the fabricated hollow wall panel structure;

S2, hoisting the lowermost hollow wall panel, so that the vertical connector passes through the reserved pumping hole of the lowermost hollow wall panel;

S3. The lowest layer of hollow wall panels is installed in place, so that the cantilevered thin walls at the ends of two adjacent hollow wall panels are spliced vertically or horizontally, and between the embedded wall panel connectors at the ends of two adjacent hollow wall panels fixedly connected; and laying hidden beams at the top of the lowest hollow wall panel, and allowing the vertical connectors to pass through the hidden beams;

S4. After the hidden beam layout is completed, according to the layout of the water and electricity lines, pre-embed the pipeline box or/water pipe in the pumping hole reserved along the hidden beam and wall panel;

S5. The concrete in the hollow wall panel of the lowest layer is poured in-situ. After the pipeline layout is completed, the concrete for the pumping holes, concealed beams and the cast-in-situ joints of the adjacent two prefabricated shear walls shall be poured in the wall panel;

S6. The construction of the hollow wall panels on the middle and top floors. During the construction process, repeat the process steps of S2-S5 in the construction of the lower wall panels.

Of course, it is also possible to complete the concrete pouring of the pumping holes and hidden beams within the entire story height range at one time after the installation of the wall panels within the entire story height range is completed.
