Prefabricated block for switch box and socket box of infilled wall masonry

Abstract

The invention relates to a prefabricated block for a switch box and a socket box of an infilled wall masonry. The prefabricated block comprises a prefabricated block body for the switch box and the socket box of the infilled wall masonry, and is characterized in that the prefabricated block body for the switch box and the socket box of the infilled wall masonry is a concrete prefabricated block with the length of 240 mm, the width of 200 mm and the height of 200 mm; a groove for accommodating a switch box body and a socket box body is arranged in a concrete prefabricated block body between the length-direction surface and the top surface of the concrete prefabricated block; one surface of the groove is communicated with the length-direction surface of the concrete prefabricated block; and the other surface of the groove is communicated with the top surface of the concrete prefabricated block. The prefabricated block for the switch box and the socket box of the infilled wall masonry has the advantages that the prefabricated block is simple in structure and convenient to manufacture, materials are saved, the phenomena of wall cracking, building block breakage and the like caused by the fact that a wall body is damaged by slotting holes formed in the rear portion of a masonry infilled wall are effectively avoided, one-time forming of a masonry project is guaranteed, a wall surface is neat, the appearance quality is good, and the quality of a masonry project is improved.

Description

technical field [0001] The invention relates to a concrete prefabricated block, in particular to a prefabricated block used for filling wall masonry switch boxes and socket boxes. Background technique [0002] In the construction of civil construction projects, some switch boxes and socket boxes are designed in the post-filling wall. The traditional method is to make a second slot on the corresponding position of the wall after the masonry is completed, and dig out the switch box or socket box groove. Hole. However, there are many shortcomings in this method. The shape and size of the grooves excavated in the wall are uneven and irregular, which makes it difficult to install in the later stage, and it is easy to cause cracks in the blocks of the wall, and seriously, it will cause the blocks in this position to break. The size and shape of the excavated slots are difficult to control, which makes it difficult and not dense to seal the wall openings after the switch box and s...

Problems solved by technology

However, there are many shortcomings in this method. The shape and size of the grooves excavated in the wall are uneven and irregular, which makes it difficult to install later, and it is easy to cause cracks in the blocks of the wall, which will seriously cause the blocks in this part to break.

The size and shape of the excavated slots are difficult to control, which makes it difficult and not dense to seal the wall openings after the switch box and socket box are installed later

In addition, the vibration generated during the slotting process will easily lead to cracks on the wall surface and loose masonry, which will easily cause cracks in the later plastering, increasing maintenance costs, and the cost of slotting is relatively high

[0003] Therefore, there are above-mentioned inconveniences and problems in the known secondary digging out switch box or socket box groove hole mode.
