Technical Field

[0001] This invention relates to the field of indoor thermal insulation flooring construction technology, specifically to a thermal insulation construction method and system for precast concrete floor slabs in large spaces. Background Technology

[0002] The construction of indoor thermal insulation flooring generally adopts the wet concrete method, which is to use commercial concrete plant to cast-in-place lightweight concrete, or the dry method, which is to mix sand, cement and lightweight concrete aggregates indoors and then spread them on site. The above two types of indoor thermal insulation flooring construction are prone to quality problems such as hollowing and cracking in the later stage. In addition, after the concrete is completed, subsequent construction processes can only be carried out after the concrete has reached the required curing period, which leads to the extension of the construction period.

[0017] Furthermore, the splicing plate a is made by mixing lightweight concrete aggregate, cement, and sand in a corresponding mold.

[0018] Furthermore, the connecting line is circular in shape, forming a complete circle when adjacent splicing plates a or b are joined together.

[0019] Furthermore, the specific steps for performing virtual shape extraction are as follows:

[0026] The precast concrete slab cutting and analysis system is suitable for constructing a three-dimensional model of the construction area based on the acquired point cloud data and calculating the required shape and area of ​​the precast concrete slab.

[0027] Furthermore, the precast concrete slab cutting analysis system includes a building data acquisition module, a concrete slab cutting calculation module, a shape cutting module, and a marking module;

[0044] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0045] In the following text, see references Figures 1-5 This invention is described.

[0046] Figure 4 This invention discloses an embodiment of a thermal insulation construction system for large-space precast concrete floor slabs. The system includes at least one point cloud data acquisition device 7. If there is only one construction area, one point cloud data acquisition device 7 can be used for data collection. If there are multiple construction areas, multiple point cloud data acquisition devices 7 can be used simultaneously, or at least one point cloud data acquisition device 7 can be used to collect data from multiple construction areas separately. The system also includes a precast floor slab cutting and analysis system 6 located on a cloud server 5. The point cloud data acquisition device 7 uses a point cloud camera, and construction personnel need to collect point cloud data of the construction area beforehand. The collected data is uploaded to the cloud server 5 via a communication device 8 for the precast floor slab cutting and analysis system 6 to perform three-dimensional modeling and calculation of the construction area.

[0047] In some embodiments, the construction drawings of the construction area can be imported as a data source into the precast concrete slab cutting analysis system 6 for three-dimensional modeling and calculation.

[0048] The difference between the two modeling methods mentioned above is that using point cloud data acquisition device 7 to collect data for modeling can obtain data from the actual construction area, resulting in a more accurate 3D model. However, the 3D model obtained by importing the construction drawings of the construction area into the precast concrete slab cutting analysis system 6 as the data source deviates from the actual completed construction area. Several adjustments are needed to calculate the area of ​​the precast concrete slab 1 and to determine the position of the tangent line in the subsequent segmentation in order to meet the construction requirements. However, its usage cost is lower than that of using point cloud data acquisition device 7.

[0049] Specifically, the precast concrete slab cutting analysis system 6 includes a building data acquisition module 61, a concrete slab cutting calculation module 62, a shape cutting module 63, and a marking module 64;

[0050] Among them, the building data acquisition module 61 is suitable for acquiring point cloud data of the construction area collected by the point cloud data acquisition device 7;

[0051] The above also includes preprocessing of point cloud data, including removing point cloud data above the preset extraction height threshold to reduce the total amount of point cloud data and improve the system's computing speed.

[0052] The extraction height threshold is set according to the actual situation. The starting point for extraction height is the ground of the construction area, and the ending point is set according to the actual situation. The distance from the starting point to the ending point is the extraction height.

[0053] Among them, the floor cutting calculation module 62 is suitable for constructing a three-dimensional model of the construction area based on point cloud data; and generating a virtual precast floor slab 1 that can saturately cover the construction area based on the three-dimensional model of the construction area, and calculating the virtual splicing plates a11 to d14 required for splicing.

[0054] The specific meaning of saturated coverage is: when the virtual precast slab 1 is superimposed on the three-dimensional model ground area of ​​the construction area, it can completely fill the ground area. Based on the obtained virtual precast slab 1, splicing plates a11 to d14 are used to splice and fill it to obtain the position and quantity of all splicing plates a11 to d14.

[0055] The shape-taking and cutting module 63 is adapted to import the virtual precast slab 1 obtained above into the three-dimensional model of the construction area, and after identifying the edge of the three-dimensional model of the construction area and performing virtual shape-taking, mark it with tangent a2 in the virtual precast slab 1; and after the construction personnel introduce construction error parameters, determine the position of tangent b3 and mark it in the virtual precast slab 1.

[0056] Virtual shaping is mainly used to identify the shape and size of the edge of the construction area, so that the precast floor slab 1 can conform to the shape and size of the construction area, reduce secondary processing in the later stage, and improve construction efficiency.

[0057] from Figures 1-3 It can be seen that tangent a2 is located on the outer side near the edge, and tangent b3 is located on the inner side away from the edge. The aforementioned tangent a2 or tangent b3 is used to mark the area that needs to be cut off from splicing panels a11 to d14. Tangent b3 is used to mark the position of the cut. During the cutting process, it is necessary to cut along tangent b3 in order to facilitate the installation of splicing panels a11 to d14.

[0058] The construction error is caused by deviations in the construction of the ground base and irregularities in the edges of the construction area. The construction error is determined according to the actual situation. Based on the calculated tangent a2, the position of tangent a2 is adjusted according to the set error value (error parameter) to obtain tangent b3. During cutting, the cutting is carried out along the position of tangent b3 to facilitate subsequent installation.

[0059] The marking module 64 is adapted to set a construction number for each virtual splicing board a11 to splicing board d14, and at the same time set different connection lines 4 between any two adjacent splicing boards a11, b12, c13 and d14.

[0060] It should be noted that the numbering is represented by numbers or letters, preferably numbers. The four-span splicing line connects two splicing plates. During subsequent installation, the accuracy of the installation position can be determined by observing the splicing line, which reduces the chance of construction errors, reduces rework, and improves construction efficiency.

[0061] Figures 1-3The structure of the precast floor slab 1 is shown. It is composed of several splicing panels a11, b12, c13, and d14. Each splicing panel a11 to d14 has a hole 17 on the same side and a pin 18 on the opposite side that can be inserted into the hole 17. The other side of splicing panel a11 has a tongue and groove joint a15. The other two sides of splicing panel b12 have tongue and groove joints b16. The other two sides of splicing panel c13 have tongue and groove joints a15. The other side of splicing panel d14 has a tongue and groove joint b16. The tongue and groove joints a15 and b16 can be interlocked. During installation, the splicing panels a11 to d14 are assembled by the pin 18 engaging with the hole 17 and the tongue and groove joints a15 and b16 engaging with each other.

[0062] In a preferred embodiment, the splicing plate a11 is made by mixing lightweight concrete aggregate, cement, and sand in a corresponding mold.

[0063] In a preferred embodiment, the wire 4 is circular in shape, forming a complete circle when adjacent splicing plates a11 or b12 are spliced ​​together.

[0064] like Figures 1-5 As shown in the figure, this invention provides a method for thermal insulation construction of precast concrete floor slabs in large spaces, including the following steps:

[0065] S1, acquire the building data of the construction area; including the size and shape parameters of the construction area;

[0066] S2, construct a three-dimensional model of the construction area based on the building data;

[0067] S3, based on the three-dimensional model of the construction area, calculate the coverage area of ​​the precast concrete slab 1 required to saturate and cover the construction area;

[0068] S4. Calculate the number and location of splicing plates a11 to d14 required for splicing precast floor slab 1 based on the coverage area of ​​the precast floor slab 1.

[0069] S5. Based on the shape of the construction area, the edge of the construction area is virtually shaped, and the position of the tangent a2 is determined at the corresponding position of the precast concrete slab 1.

[0070] The specific steps for performing virtual shape extraction are as follows:

[0071] Import the coverage area parameters of the precast floor slab 1 into the three-dimensional model of the construction area to completely cover the ground of the construction area;

[0072] Identify the edges of the construction area;

[0073] Calculate the position of the edge in the precast floor slab 1 and mark it using tangent a2;

[0074] Complete the virtual shape extraction operation.

[0075] S6, introduce construction error parameters to determine the position of tangent b3;

[0076] S7. Mark the splicing plates a11 to d14 according to the positions of tangent a2 and tangent b3 respectively, and number each splicing plate a11 to d14 according to the construction sequence.

[0077] S8, set different positions of the connecting lines 4 between any two adjacent splicing boards a11, b12, c13, and d14;

[0078] S9. Based on the parameters obtained above, precast floor slab 1 is produced and constructed in the order of the numbers.

[0079] This invention uses precast concrete floor slabs with interlocking joints for the construction of indoor thermal insulation flooring. This not only avoids the aforementioned quality problems such as hollow spots and cracks, but also allows for subsequent construction processes to be carried out immediately after the slabs are laid, greatly shortening the construction period.
