Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building construction, and particularly relates to a roof grid foundation positioning map deepening method based on BIM. BACKGROUND

[0002] With the rapid development of the real estate industry and the continuous standardization of relevant policies, the future development of the construction industry is obviously differentiated. With the increasingly fierce market competition in the construction industry, construction enterprises are facing enormous survival and development pressure, and enterprises will develop or retreat.

[0003] At present, market competition is increasingly fierce, and building engineering has shown diversified development. Modern building construction is becoming more and more complex. The traditional roof grid foundation construction sequence is to first plant a roof panel on the roof panel, then pour concrete, and finally arrange ceramic tiles. If this method is used for construction, because the roof grid foundation is constructed first and the number is large, and the grid foundation needs to be considered to be located in the middle of the ceramic tile during the later brick arrangement process, it is difficult to achieve the above requirements for the on-site roof ceramic tile arrangement, which will lead to a large number of brick cutting on the roof, seriously affecting the overall visual effect, and cannot meet the high-quality standard requirements of the project, and also increases the labor burden of workers and increases the cost input. Therefore, the traditional construction technology cannot meet the building requirements, and it is necessary to use new technology BIM (Building Information Modeling) to deepen the building information model technology.

[0029] In order to make the purpose, technical scheme and advantages of the present application more clear, specific, complete and clear, the technical scheme of the present application will be described below in conjunction with the drawings.

[0030] Please refer to Figure One The present application provides a BIM-based roof grid foundation positioning map deepening method, which comprises the following steps:

[0031] S1, measure all walls on the roof through the control lines laid on site

[0032] All walls on the roof are measured by the control line laid on site. For longer walls, at least three points, i.e. two ports and the middle part, should be measured to meet the measurement requirements. In a specific embodiment, all walls on the roof are measured by the control line laid on site. The control line is a black solid line laid on the roof panel in multiple horizontal and vertical lines, which can measure the actual size of all walls on the roof. At the same time, the control line should be marked on the inner side of the parapet. After the corresponding process of the roof is completed, the mark line should be introduced again on the roof to make it consistent with the original line. The purpose is that all sizes of the BIM deepening design brick arrangement drawing are based on this control line. Therefore, by introducing the control line, the BIM deepening design can be effectively associated with the site implementation, and the high quality standard requirements of the project can be met.

[0033] During the measurement, the minimum value is found by left and right swinging the steel ruler. The left and right swinging of the steel ruler can effectively avoid the inaccuracy of the data caused by the fact that the ruler is not straight, which in turn affects the accuracy of the deepening design of the roof brick arrangement drawing. Secondly, for longer walls, at least three points, i.e. two ports and the middle part, should be measured, the purpose of which is to find the shortest distance of the control line from the wall edge. As long as the tile arrangement on the shortest distance can be controlled, the effective arrangement of all wall edge tiles can be ensured, and the phenomenon of cutting tiles will not occur.

[0034] S2, adjusting the roof CAD drawing based on the on-site measured data

[0035] Based on the on-site measured data, the roof CAD drawing is adjusted. If it is found that the adjustment value of the roof wall line is too large, the corresponding part should be marked. After all the wall line sizes are reasonably adjusted, return to the construction site and re-measure the size of the marked part to ensure the authenticity of the data. In a specific embodiment, the roof CAD drawing is adjusted according to the data returned from the on-site measurement. During the adjustment process, if it is found that the adjustment size of the wall line is too large, the corresponding part should be marked. After all the wall line sizes are reasonably optimized, the roof construction site should be returned, and the size of all marked parts should be re-measured. Finally, the size of the wall line of the roof CAD drawing from the control line is consistent with the actual measured value on site, which ensures the correlation and accuracy of the on-site measured data and the subsequent BIM deepening design.

[0036] S3, BIM roof brick arrangement drawing deepening design based on the adjusted roof CAD drawing

[0037] Please refer to Figure Two, based on the adjusted roof CAD drawings to carry out BIM roof brick laying deepening design, the deepening design principle is: first, confirm the daughter wall and stair wall thickness, based on the thickness of the practice layer, the accurate size of the ceramic tile is reserved from the wall edge, the thickness of the wall practice layer plus 3cm of filling thickness; second, the brick joint is uniform and consistent, the separation joint is 20mm and the interval is not more than 6m, the brick laying should start from the stair wall and be arranged horizontally and vertically. In a specific embodiment, based on the adjusted roof CAD drawings, the adjusted CAD drawings are imported into Revit software for three-dimensional modeling and brick laying deepening design. Since the wall construction on the roof belongs to post-construction, therefore, before the roof brick laying deepening design, the thickness of the daughter wall and stair wall should be confirmed, based on the thickness of the practice layer, the accurate size of the ceramic tile is reserved from the wall edge, to ensure the effective construction of the wall and the roof brick laying, in this embodiment, the thickness of the practice layer is reserved by adding 3cm of extruded board filling thickness. Secondly, some matters should be paid attention to during the BIM roof brick laying process:

[0038] 1. The brick joint is uniform and consistent, which can be adjusted to 9-11mm. Adjustment is also an important part of BIM deepening design, which is often realized by adjusting the ceramic tile in the region by 1mm, and it should be noted that two adjacent extreme difference adjustment areas, such as area one is 11mm and area two is 9mm, should not be placed together.

[0039] 2. The separation joint is 20mm and the interval is not more than 6m, which is the requirement of the relevant specification.

[0040] 3. The brick laying should start from the stair wall and be arranged horizontally and vertically. The selection of stair wall to start laying is mainly to consider that the stair wall is long and high, and the ceramic tile laying problem should be solved in advance to avoid using more materials for repair in the later period; horizontal and vertical arrangement is adopted, that is, horizontal and vertical cross single row arrangement is made at the stair wall.

[0041] The brick laying only needs to ensure that most of the daughter wall, long wall and stair wall ceramic tile laying meets the requirements, and for the small short wall that does not meet the requirements, the insulation board is used for repair in the later period.

[0042] S4, based on the BIM roof brick laying deepening drawing to carry out the roof grid foundation positioning Figure Two Second deepening

[0043] Please refer to Figures Three to Five , based on the BIM roof brick laying deepening drawing to carry out the roof grid foundation positioning Figure TwoSecond deepening, the second deepening is carried out on the original design roof grid foundation base map, the roof grid foundation base is accurately located in the middle of the ceramic tile, and the position relationship of the second deepening roof grid foundation base can be quickly marked out through the control line. In a specific embodiment, the original design roof grid foundation positioning map is imported into the Revit software and combined with the BIM roof tile deepening map to carry out the second deepening of the roof grid foundation positioning map, the roof grid foundation is 400*400mm and 200*400mm, Figure Four The grid foundation size is 400*400mm, the horizontal and vertical directions of the original design grid foundation are adjusted by 50mm and 40mm respectively, so that it is located in the middle of the ceramic tile; Figure Five The grid foundation size is 200*400mm, the horizontal and vertical directions of the original design grid foundation are adjusted by 35mm and 30mm respectively, so that it is located in the middle of the ceramic tile.

[0044] Through the BIM roof tile deepening map, the positions of all roof grid foundations can be quickly adjusted, so that they are accurately located in the middle of the ceramic tile, meet the high-quality standard requirements, and the position relationship of the second deepening roof grid foundation can be quickly marked out through the control line.

[0045] S5, confirming whether the deepened roof grid foundation positioning map is reasonable

[0046] Discuss and confirm with the roof-related professional and technical personnel and the grid manufacturer whether the deepening of the roof grid foundation positioning map is reasonable, and put forward the deepening deficiency and improvement opinion, until the relevant units reach a unified opinion, and finally complete the deepening of the roof grid foundation positioning map. In a specific embodiment, through the above-mentioned roof grid foundation positioning deepening map, the general contractor unit leads the discussion and confirmation of whether the deepened roof grid foundation positioning map is reasonable by the professional and technical personnel of the roof units, and the deficiency and improvement opinion of each unit is further deepened until the relevant units reach a unified opinion, and finally the deepening work of the roof grid foundation positioning map is completed.
