Description

A concrete prefabricated wall panel

technical field

The utility model relates to a prefabricated wallboard, in particular to a concrete prefabricated wallboard.

Background technique

Prefabricated buildings are an important embodiment of the integration of low-carbon concepts in my country's social development. They provide flexible construction ideas for urbanization, improve the speed of my country's urbanization process, and promote the sound and rapid development of socialist social economy. The use of prefabricated wall panels to build prefabricated buildings can improve the degree of factory and mechanized construction, reduce on-site wet work, save on-site labor, overcome seasonal influences, and shorten the construction period. At present, when carrying out project decoration, it is often necessary to re-drill holes on the prefabricated wall panels for hoisting various types of pipes, which increases labor, and the impact of the electric drill on the wall panels is likely to cause cracking of the prefabricated wall panels, affecting the progress and quality of the project .

Utility model content

The technical problem to be solved by the utility model is to provide a concrete prefabricated wall panel, which avoids the problem of cracking caused by opening holes, and improves the progress and engineering quality of prefabricated construction projects.

To solve the problems of the technologies described above, the technical scheme adopted by the utility model is as follows:

A concrete prefabricated wall panel, in which horizontally and vertically arranged steel bars are pre-embedded, on the surface of the concrete prefabricated wall panel, there are circular tubes left in it during pouring, and the circular tubes run through the concrete precast wall front and back The through hole in the middle of the round tube forms a reserved hole, and the round tube and the steel bar are staggered from each other.

Further, the reserved holes are regularly arranged horizontally and vertically.

Further, the distances between the left and right adjacent reserved holes and the upper and lower adjacent reserved holes are all multiples of 100mm, 150mm, 200mm, or 300mm.

Further, the diameter of the reserved hole is 10-30 mm.

Further, the concrete prefabricated wall panel is made by one-time pouring molding process.

Further, the concrete prefabricated wall panel is a prefabricated shear wall panel, a prefabricated inner wall panel or a prefabricated outer wall panel.

Compared with the prior art, the utility model has the following beneficial effects:

The surface of the concrete prefabricated wall panel of the utility model is distributed with round tubes left in it during pouring, and the middle through hole of the round tube forms a reserved hole, which avoids the problem of cracking caused by opening the hole. In the prefabricated construction project, the prefabricated The reserved holes can be used for hoisting installation, mold fixing, decorative decoration and temporary support, and can also be used for anchoring of wire pipes, water pipes, fire pipes, air conditioning installations, curtain walls and insulation layer installations, which solves the problem of opening prefabricated wall panels during construction. The problem of cracking the wallboard caused by the hole improves the progress and quality of the prefabricated construction project, improves the safety, and facilitates the later construction of the workers.

Detailed ways

A concrete prefabricated wall panel as shown in Figure 1 and Figure 2, the concrete prefabricated wall panel is formed by pouring concrete 1, and horizontally and vertically arranged steel bars 3, 4 are pre-embedded in it, and the concrete prefabricated wall panel There are circular tubes left in it during pouring, and the circular tubes run through the prefabricated concrete wall panels front and back, that is, the circular tubes can be fixed on the formwork corresponding to the position of the reserved hole 2 during pouring. After the pouring is completed and demoulding, The round pipe is left in the concrete prefabricated wallboard, and the middle through hole of the round pipe forms a reserved hole 2 .

The circular pipe and the steel bar are staggered, and the reserved hole 2 is located at the center point of the square grid formed by the horizontal and vertical steel bars 3 and 4. The diameter of the reserved hole 2 is 10-30 mm, which can meet the force requirements. The reserved holes 2 are regularly arranged horizontally and vertically, and the distance between the left and right adjacent reserved holes 2 and the upper and lower adjacent reserved holes 2 is a multiple of 100mm or 150mm or 200mm or 300mm.

The concrete prefabricated wall panel is made by one-time pouring molding process, that is, the forming cavity is composed of building templates, and concrete 1 is poured from the upper opening of the forming cavity, and the prefabricated wall panel of the final shape is formed in one time in the forming cavity, and the one-time pouring molding guarantee The quality of the surface of the wall panel is avoided, and the layered cracking of the wall panel is avoided, and the molding cavity is formed by the formwork. The cavity is vertical, and the opening is on the top. .

The concrete prefabricated wall panel of the utility model can be used as a prefabricated shear wall panel, a prefabricated inner wall panel and a prefabricated outer wall panel, and the last unused reserved holes on the concrete prefabricated wall panel can be sealed or filled at a later stage.

The above-mentioned embodiments of the utility model are not limiting the protection scope of the utility model, and the implementation manner of the utility model is not limited thereto. On the premise of not departing from the above-mentioned basic technical idea of the present utility model, other modifications, replacements or changes made to the above-mentioned structure of the present utility model in various forms shall fall within the protection scope of the present utility model.
