Detailed Description

The present disclosure will be described in further detail with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not to be construed as limitations of the present disclosure. It should be further noted that, for the convenience of description, only the portions relevant to the present disclosure are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present disclosure may be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, fig. 1 is a view of a prefabricated laminated wall element in one form, in which a prefabricated laminated wall element 100 includes a first leaf 110 and a second leaf 120 spaced apart to form a cavity 130, and the two leaves are connected by a connecting assembly 140. The formed cavity 130 can reduce the weight of the prefabricated components, is easy to hoist during installation and construction, and when a plurality of prefabricated superposed wall components form a continuous building wall body, the post-cast concrete in the cavity forms a continuous interface to form a continuous structure body and can play an effective waterproof role.

The prefabricated laminated wall element 100 is typically formed on a formwork table, wherein the first and

second leaves

110, 120 are preferably formed of concrete material. The connecting assembly 140 is a steel bar cage or a connecting body composed of steel bars, and the connecting assembly 140 can not only enhance the strength of the blade plate, but also play a role in connecting the two blade plates, so that the blade plates are formed into a spaced form. Specifically, the connection assembly 140 includes a first reinforcing mesh 141 and a second reinforcing mesh 142, the first reinforcing mesh 141 is embedded in the first blade 110, the second reinforcing mesh 142 is embedded in the second blade 120, and the connection reinforcing bars or truss reinforcing bars 143 are disposed between the first reinforcing mesh 141 and the second reinforcing mesh 142, and are used for connecting the first blade 110 and the second blade 120.

In another specific embodiment, as shown in FIG. 2, FIG. 2 is a top view of the preformed laminated member shown. Wherein the connecting assembly 140 includes a first longitudinal rib 144 and a second longitudinal rib 145, the first longitudinal rib 144 is disposed in the first blade 110, the second longitudinal rib 145 is disposed in the second blade 120, and the hoop rib 146 connects the first longitudinal rib 144 and the second longitudinal rib 145, so that the first blade and the second blade form a spaced-apart form.

In this application, "outer surface" for a louver refers to the surface of the louver facing the outside of the component, and "inner surface" for a louver refers to the surface of the louver facing the cavity.

As shown in fig. 3, a first contact surface 151 and a second contact surface 152 are provided on an edge of an inner surface of the first blade 110, and the first contact surface 151 and the second contact surface 152 together form a waterproof member accommodating area 150. The flashing receiving area 150 is substantially channel shaped with a top opening at the first end 111 of the first blade 110, a side opening at the inner surface 112 of the first blade, and two end openings at the first side end 113 and the second side end 114 of the blade, respectively. The flashing receiving area extends through the leaf from a first side end 113 to a second side end 114 thereof.

Flashing receiving area 150 is configured to receive a flashing member, such as a water-swellable stop or other form of flashing that can function to stop or absorb water. The first contact surface 151 forming the flashing receiving area intersects the first end 111 of the blade, the second contact surface 152 intersects the inner surface 112, and the first contact surface 151 intersects the second contact surface 152, thereby forming the flashing receiving area. The flashing receiving area may expose the flashing to a gap formed by the two parts, for example, a gap formed when the first end 111 is spliced to another prefabricated member, or a gap formed by the inner surface 112 and cast-in-place concrete in the cavity 130. Thereby, the waterproof part can prevent water leakage and water seepage of gaps which are not in the same plane. In the present application, the waterproof is only an exemplary feature, which may also be replaced by a liquid-proof, gas-proof or sound-proof piece.

The waterproof member accommodating area 150 provided on the prefabricated overlapping member 100 can simplify the construction process of laying the waterproof member in the later construction process, so that the waterproof member has a settable space. In addition, the waterproof accommodating area 150 is designed inside the prefabricated overlapping member 100, so as to prevent the prefabricated overlapping member from invading the outer space of the member as much as possible, and other waterproof measures can be added at the position where a gap is formed, so as to achieve multiple waterproof functions.

Preferably, the flashing receiving area 150 comprises a first contact surface 151 and a second contact surface 152, the first contact surface 151 and the second contact surface 152 each having a surface roughness less than the surface roughness of the inner surface 112 of the member 100 to receive the flashing in a smoother plane to facilitate the positioning of the flashing.

As shown in fig. 4, fig. 4 is an enlarged schematic view of the waterproof member accommodating area 150. The width of the first contact surface 151 is a, preferably, a is 5mm ≦ a ≦ 25mm, and the width of the second contact surface 152 is b, preferably, b is 10mm ≦ b ≦ 40 mm.

Preferably, a ≦ b.

Another form of flashing receiving area is disclosed and figure 5 shows a schematic end view of another form of flashing receiving area. As shown in fig. 5, the waterproof member accommodating area 150 is disposed at the first end 111 of the first blade 110, and has a top opening opened at the first end 111 of the first blade 110 and two end openings opened at the first side end 113 and the second side end 114 of the blade, respectively.

This form of flashing receiving area comprises 3 contact surfaces, namely a first contact surface 151, a second contact surface 152 and a third contact surface 153. Set up 3 contact surfaces and be favorable to firm waterproof, make waterproof centre gripping in the space that 3 contact surfaces formed.

Another form of flashing receiving area disclosed herein is shown in fig. 6, where fig. 6 shows a schematic end view of another form of flashing receiving area. This form of flashing receiving area includes an arcuate contact surface. For example, in the embodiment of FIG. 5, the second contact surface 152 is an arcuate contact surface. Including circular arc contact surface can be convenient for by the formation, in addition, circular arc contact surface does benefit to the installation of waterproof, avoids bight to deposit water or other pollutants.

Another form of flashing receiving area disclosed herein is shown in fig. 7, where fig. 7 shows a schematic end view of another form of flashing receiving area. In fig. 7, the flashing receiving area comprises a first contact surface 151, a second contact surface 152 and a third contact surface 153, wherein the first contact surface 151 and the third contact surface 153 form a receiving area with a cross-sectional shape that is small-bottomed. This form of flashing receiving area facilitates the installation of the flashing. The cross-sectional shape is a shape with a large mouth and a small bottom, i.e. the size of the top opening near the first end 111 is larger than the size of the bottom opening near the inner part of the louver. The section of the shape is favorable for guiding the waterproof part to expand along the path constrained by the shape of the section after absorbing water, so that more waterproof parts are expanded at a larger opening, the water stop area of the waterproof part is increased, and the waterproof part is more favorable for waterproofing.
