[0028] As shown in Figure 1 , the C-type stockyard includes a ground part, a lower reinforced concrete retaining wall 1 part and an upper unloading platform 5 part, the present application introduces a BIM-based assembly type C-type stockyard construction method, which includes the following steps.

[0029] a. Using BIM technology, the upper unloading platform 5 of the stockyard is divided into a plurality of concrete beam plate modules.

[0030] b. Perform the construction of the lower reinforced concrete retaining wall 1 structure of the stockyard.

[0031] c. While performing the reinforced concrete retaining wall 1 construction, the support plate 6 is prefabricated outside the site according to the concrete beam plate modules divided in step a.

[0032] d. Perform the construction of the column 2 and main beam 3 combination of the unloading platform 5, as shown in Figure 2 .

[0033] e. Install the secondary beam 4 between the adjacent two main beams 3.

[0034] f. Install the support plate 6 on the secondary beam 4, as shown in Figure 3 .

[0035] g. Tie the steel on the support plate 6 and install the embedded parts, and then perform the pouring construction of the concrete beam plate module.

[0036] h. After the unloading platform 5 construction is completed, the ground floor reinforced concrete structure is constructed.

[0037] Before performing the C-type stockyard construction, the C-type stockyard is divided into modules using BIM technology, including dividing the reinforced concrete retaining wall 1 and dividing the unloading platform 5.

[0038] The reinforced concrete retaining wall 1 is divided into several regions by using the BIM technology, is divided into several layers along the height direction, and is divided into several segments along the length direction for each layer. During the construction of the reinforced concrete retaining wall 1, the layers are constructed from bottom to top, and the segments are constructed in the middle of each layer at intervals. Through the construction at intervals, the two adjacent regions are not continuously constructed, but are constructed at intervals, so that the stress of the already poured part is fully released, and after the stress is released, the subsequent region can be directly poured, without the need of reserving a post-pouring gap, and the construction efficiency is improved.

[0039] In the division of the reinforced concrete retaining wall 1, every 3.6 meters along the height direction is a layer, and every 40 meters along the length direction is a segment.

[0040] As shown in Figure 4 , Figure 5 The support plate 6 includes a reinforced concrete plate, the length of the reinforced concrete plate is equal to the interval between two adjacent main beams 3, so that after the support plate 6 is placed on the secondary beam 4, the two ends of the support plate 6 are just lapped on the two main beams 3. A plurality of rows of binding steel bars 7 are arranged on the upper plate surface of the reinforced concrete plate, and the outer steel bars 8 are arranged on the side edges of the two ends of the reinforced concrete plate, respectively.

[0041] When the support plate 6 is installed on the secondary beam 4, the two ends of the reinforced concrete plate are aligned with the two adjacent main beams 3, respectively, and the outer steel bars 8 are connected with the reserved steel bars on the top of the main beams 3, and the part is poured together during pouring, so as to realize the connection between the support plate 6 and the main beams 3, and the support plate 6 is supported by the secondary beam 4 below at the same time.

[0042] In step g, when the steel bars are bound before pouring, the steel bars are bound on the binding steel bars 7, so that when pouring, the newly poured concrete and the reinforced concrete plate of the support plate 6 can be integrated.

[0043] When the steps f and g are constructed, the beam plate modules divided in step a are sequentially constructed in segments until the construction of the entire unloading platform 5 is completed.

[0044] The present application utilizes the BIM technology to divide the C-shaped stockyard into modules, and constructs according to the modules, especially for the unloading platform 5 of the cantilever structure, the prefabricated support plate 6 is used instead of the existing pouring formwork, and the scaffold is not needed to be erected for the pouring formwork as usual, after the support plate 6 is installed, the pouring of the unloading platform 5 is directly performed on the support plate 6, and after the pouring is completed, the support plate 6 becomes a part of the unloading platform 5, without the need of subsequent form removal operation.

[0045] The support plate 6 is manufactured in a factory, and the manufacturing quality is ensured through the factory manufacturing, and the on-site workload is reduced; on site, mainly the modules are assembled, the assembling process is hoisted into position by using a car crane, and high-altitude operation is reduced.

[0046] The upper structure in time can be constructed in parallel with the lower structure, and the construction time is shortened. The prefabricated support plate 6 can avoid the erection, removal, transportation, maintenance and storage of the scaffold body of thousands of tons, and can also avoid the complex procedures of the super-dangerous project. At the same time, after the upper structure construction is completed, the load-bearing frame does not need to wait for maintenance to reach 100% strength before removal, and the ground civil construction and equipment installation process construction can be arranged. Finally, the effect of greatly reducing the cost and shortening the construction period is achieved.
