Fig. 1(a) and 1(b) illustrate a precast concrete wall panel 100 provided by an embodiment of the present invention, which includes a wall panel body 110 and a connection part 120. The connection part 120 is disposed on a surface of the wall panel body 110 in a height direction and a width direction, and includes at least one protrusion 121, an accommodation space 122, and a connection bar 123.

In this embodiment, the connecting portion 120 includes two protrusions 121. The protrusion 121 includes a connection end surface (i.e., an end surface where the prefabricated composite wall panel is connected to another wall panel) 121a, and the connection bar 123 includes a first side 123a adjacent to the connection end surface 121 a. The receiving space 122 is for receiving a connection bar 123. The term "contain" as used herein means "partially or completely located", that is, the connection bar 123 contained in the containing space 122 means that the connection bar 123 is partially or completely located in the containing space 122. Wherein the connection bar 123 includes a first side 123a adjacent to the connection end surface 121 a. The connector bar 123 in this embodiment is a rectangular bar or a stirrup ring and therefore also has a second side 123b remote from the connector end face. It should be noted that, in the present invention, the connecting reinforcement 123 may also be in other shapes, and may not have a second side (for example, in a "]" shape), as long as the relevant effect can be achieved.

In this embodiment, the receiving space 123 is located in the protrusion 121. The connection bars 123 are movable in the accommodation space 122 so as to be disposed in the accommodation space 122 in an inclined state (as shown in fig. 1 (a)) or a horizontal state (as shown in fig. 1 (b)), and when the connection bars 123 are disposed in the accommodation space in the horizontal state, the first sides 123a protrude out of the connection end surfaces 121 a. In the transportation and hoisting links, the connecting steel bars 123 are disposed in the accommodating space 122 in an inclined state, and do not extend out of the connecting end surface 121a, so that the transportation and hoisting of the precast concrete wall panel 100 are not disturbed. In this embodiment, the accommodating space 122 includes a transverse hole 122a and a first longitudinal hole 122b which are communicated with each other.

For clarity, fig. 1(a) is partially cut away to expose the connecting steel bars 123, and the shadow is a cutting plane; in order to more clearly express the technical features of the present invention, the reinforcing bars in the precast concrete wall panel 100 when partially cut are not shown.

Fig. 2 shows that the utility model provides a precast concrete concatenation wallboard 200, it includes concatenation wallboard body 210 and the concatenation portion 220 of setting on the face at the direction of height and the width direction place of concatenation wallboard body 210, concatenation portion 220 includes concatenation hole 221. In this embodiment, the splicing hole 221 includes a transverse hole 221a and a longitudinal hole 221b that are connected to each other. Wherein the sum of the width of the receiving space 122 (i.e., the depth of the transverse hole 122 a) and the width of the splicing hole (i.e., the depth of the transverse hole 221 a) is greater than or equal to the length of the connecting bar 123.

Fig. 3 shows a schematic cross-sectional view of a precast concrete wall body 1000 spliced by the precast concrete wall panel 100 shown in fig. 1 and the precast concrete joined wall panel 200 shown in fig. 2. The first and second sides 123a and 123b of the connection bar 123 are in the splicing part and the receiving part of the precast concrete spliced wall panel 200 and the precast concrete wall panel 100, respectively.

Since the distance between the precast concrete wall panel 100 and the precast concrete joined wall panel 200 is very small and the area is very large, it is difficult to directly contact the connecting reinforcing bars 123 to adjust the positions of the connecting reinforcing bars 123; however, since the connecting reinforcement 123 has a tendency to change from an inclined state to a horizontal state under its own weight, the indirect disturbance can also turn the connecting reinforcement 123 to a horizontal state; thus, even if the distance between the precast concrete joined wall panel 200 and the precast concrete wall panel 100 is very small, and no operation space is available, and the connecting bars cannot be directly contacted, the connecting bars 123 can be disturbed to be adjusted from the inclined state to the horizontal state, for example, the precast concrete wall panel 100 is vibrated; the connecting reinforcing steel bars 123 connecting the precast concrete spliced wallboard 200 and the precast concrete wallboard 100 have the automatic in-place performance, so that the automatic installation of the connecting reinforcing steel bars is realized, and the convenience and the rapidness are realized. Concrete is then poured into the space formed between the precast concrete wall panels 100 and the precast concrete joined wall panels 200, including the first longitudinal holes 122b and the longitudinal holes 221b, so that the precast concrete wall panels 100 and the precast concrete joined wall panels 200 are fixedly connected together to form a precast concrete wall body 1000 (the post-poured concrete is not shown).

As shown in fig. 4, the connecting portion 120 of the precast concrete wall panel 100 further includes a first longitudinal rib 124, and the first longitudinal rib 124 is disposed in the first longitudinal hole 122 b. The second side 123b of the connecting reinforcement 123 is connected to the first longitudinal bar 124.

In this embodiment, the first longitudinal bar 124 can be moved so that the connection bar 123 is disposed in the accommodating space 122 in an inclined state or a horizontal state. One technique is to connect the second side 123b of the reinforcement bar 123 to the first longitudinal bar 124. Pulling the first longitudinal bar 124 longitudinally upwards or pushing the first longitudinal bar 124 downwards to drive the connecting steel bar 123 to be in an inclined state; the first longitudinal bar 124 is moved in the opposite direction to adjust the connecting bar 123 to be horizontal. In other embodiments of the present invention, the second side 123b can move up and down along the length direction of the first longitudinal rib 124, so as to be disposed in the accommodating space 122 in an inclined state or a horizontal state.

In this embodiment, two first longitudinal ribs 124 are disposed in each first longitudinal hole 122b, and the two first longitudinal ribs 124 are located on the other surface of the first longitudinal hole 122b far from the connecting end surface 121a, and are connected to the second side 123b of the connecting reinforcement 123 in a horizontal state.

For clarity, fig. 4 is partially cut away to expose the connecting steel bar 123 and the first longitudinal bar 124, and the shadow is a cutting plane; in order to more clearly express the technical features of the present invention, the reinforcing bars in the precast concrete wall panel 100 when partially cut are not shown.

Fig. 5 shows a schematic cross-sectional view of a precast concrete wall body 2000 formed of the precast concrete wall panel 100 shown in fig. 4 and the precast concrete joined wall panel 200 shown in fig. 2.

Fig. 6 shows another form of precast concrete wall 2000. In the embodiment shown in fig. 6, a third longitudinal bar 222 is provided in the longitudinal hole 221b of the splicing hole 221 of the precast concrete spliced wall panel 200, wherein the third longitudinal bar 222 is connected to the first side 123a of the connecting bar 123.

The utility model discloses in, precast concrete wallboard 100's connection terminal surface 121a can set up on any one of three faces of arch 121. The embodiment of fig. 7 has the connection end surface 121a perpendicular to the wall panel body 110.

For clarity of expression, fig. 7 is partially cut away to expose the connecting steel bars 123, and the shadow is a cutting plane; in order to more clearly express the technical features of the present invention, the reinforcing bars in the precast concrete wall panel 100 when partially cut are not shown.

Fig. 8 shows another embodiment of a precast concrete wall panel 100, in which the connecting end surface 121a has the same direction as that of fig. 7, and a first longitudinal rib 124 is provided in the receiving space 122.

For clarity, fig. 8 is partially cut away to expose the connecting steel bar 123 and the first longitudinal bar 124, and the shadow is a cutting plane; in order to more clearly express the technical features of the present invention, the reinforcing bars in the precast concrete wall panel 100 when partially cut are not shown.

Fig. 9 is a schematic cross-sectional view of a precast concrete wall 3000 formed by connecting 2 precast concrete wall panels 100 shown in fig. 8, wherein the connecting reinforcements 123 are connected, concrete (not shown) is poured into a space formed between the precast concrete wall panels, and the connection process is similar to the precast concrete wall 1000 shown in fig. 3 and is not repeated herein. With the connection configuration shown in fig. 9, compared with the configuration shown in fig. 6, the protrusion 121 protrudes out of the wall plate body 110 by a larger size, which is beneficial to the arrangement of the connection steel bars 123 with a larger size: in one embodiment, if the thickness of the precast concrete wall 3000 is 240mm and the thickness of the wall panel body 110 is 40mm, the protrusion 121 protrudes out of the wall panel body 110 by a size of 150mm, which is very convenient for installing the connection part and the connection steel bar. However, with the structure shown in fig. 6, if the thickness of the precast concrete wall is 240mm and the thickness of the wall panel body 110 is 40mm, the size of the protrusion 121 protruding out of the wall panel body 110 is about 70mm, which makes the manufacturing difficult. Thus, from another perspective, the thickness of precast concrete wall 3000 can be reduced using the joint construction shown in fig. 9, for example, the thickness of precast concrete wall of the modular building shown in fig. 23, which is composed of precast concrete wall panels, can be 240mm or less to 200mm, while the thickness of precast concrete wall of the modular building of the prior art can be up to 300mm or even 400 mm.
