Specific implementation manners

[0018] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0019] Please refer to Figures 1-3, the present utility model provides an implementation scheme: In the process of modern building construction, when connecting the wall panels of prefabricated buildings after prefabrication, grouting connection is often used. However, in the structure of grouting connection, the pure concrete structure formed by grouting cannot effectively play an earthquake-resistant role. When subjected to horizontal vibration, horizontal fracture of the grouting cylinder is likely to occur.

[0020] In view of the above problems, this application discloses an energy-saving, environmentally friendly and earthquake-resistant prefabricated building wall. The wall is composed of a prefabricated wall base 1 and a prefabricated wall main body 6. The prefabricated wall base 1 and the prefabricated wall main body 6 adopt a concrete structure. The prefabricated wall base 1 is a rectangular plate of concrete structure, and the prefabricated wall main body 6 extends from the prefabricated wall base 1. A steel reinforcement cage 5 is arranged on the prefabricated wall base 1, and the prefabricated wall main body 6 is arranged on the prefabricated wall base 1. The prefabricated wall main body 6 is a concrete structure wrapped outside the steel reinforcement cage 5, and the two are internally reinforced through the steel reinforcement cage 5;

[0021] According to the attached drawings of the specification Figures 1-3 it can be seen that, furthermore, a number of embedded sleeves 2 are arranged on the prefabricated wall base 1, and a number of embedded vertical rods 3 are arranged on the ground corresponding to the prefabricated wall base 1. The number of embedded vertical rods 3 are inserted into the number of embedded sleeves 2. When installing the prefabricated wall panel, the embedded sleeve 2 is aligned with the embedded vertical rod 3 for insertion, which plays a role of guiding and strengthening. A transverse connection and strengthening grouting assembly 4 is arranged on any embedded sleeve 2. Through the transverse connection and strengthening grouting assembly 4, grout is injected into the embedded sleeve 2, thereby connecting the embedded sleeve 2 and the embedded vertical rod 3 to form a complete bottom concrete structure;

[0022] Specifically, according to the attached drawings of the specification Figures 1-3 it can be seen that the above-mentioned transverse connection and strengthening grouting assembly 4 includes a transverse connection rod 41. The transverse connection rod 41 is fixed at the top of the embedded sleeve 2, and the end of the transverse connection rod 41 extends to the outside of the prefabricated wall base 1. A pair of strengthening rods are symmetrically arranged at the bottom of the transverse connection rod 41 on both sides of the embedded sleeve 2;

[0023] In the specific implementation process, the transverse connection rod 41 is communicated with the embedded sleeve 2 and extends horizontally out of the prefabricated wall base 1. The transverse connection rod 41 forms a T-shaped head at the top of the embedded sleeve 2. On the one hand, the transverse connection rod 41 is used as a grouting channel, and on the other hand, with the assistance of a pair of strengthening rods, the combination of the embedded sleeve 2 and the prefabricated wall base 1 is more sufficient, improving the horizontal earthquake resistance. Furthermore, the pair of strengthening rods and the bottom of the embedded sleeve 2 are connected through an integral foundation groove 46, further strengthening the horizontal earthquake resistance effect, and at the same time, through the integral foundation groove 46, the contact area between the concrete foundation and the wall ground is enlarged, improving the horizontal earthquake resistance;

[0024] To achieve the grouting operation, the above-mentioned transverse connection and reinforcement grouting assembly 4 further includes a slurry discharge hole 42. A slurry discharge hole 42 is provided in the center of the transverse connection rod 41. A grouting through hole is provided on the integral foundation trench 46 and communicated with the embedded sleeve 2. The inner cavity of the embedded sleeve 2 communicates the grouting hole 44 with the slurry discharge hole 42. One side of the grouting hole 44 extends out a grouting rod 43, and the grouting rod 43 extends to the outer wall of the precast wall bottom foundation 1.

[0025] In the specific implementation process, through the setting of the grouting rod 43, grouting can be carried out into the integral foundation trench 46 and the embedded sleeve 2 through the grouting hole 44. When the grouting overflows from the slurry discharge hole 42, it is regarded as the completion of grouting. The concrete foundation formed after grouting and the embedded sleeve 2, the embedded vertical rod 3 and the transverse connection rod 41 form an interactive composite reinforced concrete foundation, which has higher seismic resistance compared with the concrete foundation formed by single grouting.

[0026] As a preferred solution, furthermore, the width of the precast wall bottom foundation 1 is the same as that of the precast wall body 6 to ensure the consistency of the wall.

[0027] As a preferred solution, furthermore, the transverse connection rod 41 and the grouting rod 43 are arranged in parallel, and the transverse connection rod 41 and the grouting rod 43 are integrally formed with the embedded sleeve 2, which is convenient for grouting production.

[0028] As a preferred solution, furthermore, both the transverse connection rod 41 and the grouting rod 43 are plate-shaped structures with a cylindrical shape. The transverse connection rod 41 and the grouting rod 43 are arranged in parallel, and the transverse connection rod 41 and the grouting rod 43 are integrally formed with the embedded sleeve 2.

[0029] As a preferred solution, furthermore, the two strengthening rods are connected to both sides of the embedded sleeve 2 through a pair of triangular reinforcing plates 45, which further improves the connection tightness of the steel members between the embedded sleeve 2, the strengthening rods and the transverse connection rod 41.

[0030] As a preferred solution, furthermore, several pairs of fixing rods 7 are arranged at the bottom end of the steel reinforcement cage 5 and buried in the precast wall bottom foundation 1 to enhance the connection tightness between the precast wall bottom foundation 1 and the precast wall body 6.

[0031] Generally speaking, the energy-saving, environmental protection and earthquake-proof precast wall of this building adopts the precast wall assembly construction. The construction process is simple and green. An integral embedded sleeve 2 and a transverse connection and reinforcement grouting assembly 4 are provided on the foundation of the precast wall. The transverse connection and reinforcement grouting assembly 4 and the embedded sleeve 2 can form a reinforced steel mesh for strengthening the wall bottom foundation, so that the combination and support between the wall and the ground during grouting are better, and further enhance the seismic resistance of the connection position between the precast wall and the ground.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
