Grooving-free masonry construction method based on BIM technology and prefabricated building blocks and grooved building blocks

Abstract

The invention relates to the technical field of building construction, in particular to a grooving-free masonry construction method based on a BIM technology and prefabricated building blocks and thegrooved building blocks. An electromechanical model and a structure model are combined, arrangement of the building blocks for masonry wall bodies is adjusted according to the electromechanical modeland a grooved building block model, staggered joint masonry between the grooved building blocks and the building blocks for the masonry wall bodies is achieved, it is guaranteed that the grooved building blocks and the building blocks for the masonry wall bodies are mutually clamped to form a whole, and the stability after building forming is improved; the BIM model and portable projection equipment are used for projecting to the site for construction on the same screen, so that the construction accuracy and efficiency are guaranteed; and by combining the prefabrication of the grooved buildingblocks and the building blocks for the masonry wall bodies, the standardized masonry members are prepared in a fixed-point centralized mode, the scattering of the construction waste is reduced, the generation amount of the construction waste is reduced, the labor intensity of the construction waste collection is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a slot-free masonry construction method based on BIM technology and prefabricated blocks and a block with slots. Background technique [0002] With the increasing emphasis on green construction and strict control, it has become the focus of the construction industry to actively take measures to control the amount of waste generated by construction and reduce the cost of construction waste cleaning. [0003] Autoclaved aerated concrete blocks are used as materials for building enclosures and filling structures. They have excellent thermal insulation properties and have been widely used in the construction industry. However, due to the low price of aerated concrete blocks, the cost control of the construction industry The impact is small, and it is often easily overlooked by project managers, causing the loss rate of aerated concrete blocks to reach about 5% during us...

Problems solved by technology

It can be seen that the scheme applies the installation of the water and electricity pipeline box in advance, and uses the blocks and prefabricated concrete components cut and processed on site to wrap the pipeline box, so as to realize one-time masonry forming and avoid opening grooves on the wall after the masonry is formed. It leads to quality hazards such as hollowing, cracking, and wall leakage on the wall; however, this technical solution requires a higher technical level of the masonry workers, resulting in a relatively high cost of masonry, and in the process of masonry, it is still necessary to On-site cutting of blocks, resulting in scattered distribution of construction waste between floors and buildings, resulting in a large amount of construction waste and high waste cleaning costs; it is difficult to meet the requirements of green construction

In addition, because the pipeline needs to be installed in a confined space, it is difficult to divide the pipeline and ensure the construction quality.

[0005] Not only that, in the prior art, in order to improve the convenience of installing wire pipes and wire boxes on the wall made of blocks, it is avoided to use cutting equipment to open wire pipe grooves and wire boxes on the wall after the wall is formed. Box slots, and then put the wire pipes and wire boxes into the wall, resulting in low construction efficiency, and the defects of cutting a large amount of construction waste. The modification of the concrete block structure for masonry has been studied, such as : The patent application number is 202010729156.9 which discloses that the threading wall is embedded on the main wall. The threading wall includes a wire box block and a plurality of wire pipe blocks built on the wire box block. It can be seen that the structural design of the device is unreasonable , leading to two problems: the first aspect: it is impossible to form a staggered installation between the main wall and the main wall, resulting in poor stability between the threading wall and the main wall; the second aspect: during the masonry process In this case, the pipelines can only be arranged in the vertical direction, and when it is necessary to adjust the pipeline layout position, it is still necessary to re-groove the main wall for installation, for example: it is necessary to distribute the pipelines from the lower right corner of the wall to the wall In the upper left corner of the upper right corner, it can only be laid vertically upwards from the lower right corner to the top of the upper right corner, and then use cutting equipment to cut out the wire pipe groove to the upper left corner from the top of the upper right corner, and then realize the wire pipe installation; or directly from the right The lower corner is cut to the upper left corner by cutting equipment to realize the installation of wire pipes. This process is not only easy to generate construction waste, but also cumbersome to construct
