[0002] With the rapid development of the national economy and cities, in order to meet the needs of the general public for improved work and life quality, various large venues, hospitals and other public buildings have emerged in large numbers. The mechanical and electrical installation, intelligentization, medical special equipment and pipelines of such public buildings are intricate. In order to realize the use function of the building, higher floor height requirements are required than ordinary building engineering spaces. The corresponding secondary structure masonry and secondary structure concrete components have high construction height and large volume. The traditional construction method is used, which is difficult to construct and has a long construction period. The appearance quality of the concrete components is poor, and a large number of secondary turnover materials such as formwork, wooden squares, and tension screws are required. Summary of the invention

[0003] The present invention is aimed at the above-mentioned problems and specifically designs a construction method for secondary structure concrete components using standardized brick molds based on modular design, so that it can be combined with BIM software to simulate the layout and assembly of secondary structure concrete components, extract the parameters of the unit modules that constitute the secondary structure concrete components, and design and process standardized brick molds.

[0004] To achieve the above object, the present invention provides a method for constructing a secondary structure concrete member using a fixed brick mold based on a modular design, comprising the following steps: Step 1: Based on the general description of the building and structural construction design, structural drawings, architectural drawings, and relevant requirements of the design and construction specifications, use CAD and BIM software to conduct in-depth design and drawing of the secondary structural concrete components of all floors of the building; Step 2: Before the formal construction of the masonry secondary structure, check the position relationship between the main concrete structure and the secondary structure, and review the detailed design drawings based on the actual situation. Adjust the positions where the relevant parameters between the main structure and the secondary structure are significantly different, and ask the design unit to confirm. After verification and confirmation, the number of unit modules of secondary structural concrete components on each floor shall be counted and summarized; Step 3: According to the secondary structure detailed design drawings confirmed by the design unit, select representative walls, and use BIM modeling to simulate the layout and assembly of masonry and fixed brick molds; After the overall layout drawing is completed, the secondary structure concrete components are decomposed into unit modules; Step 4: According to the decomposed unit module parameters, combined with the actual situation on site and the construction progress requirements, adopt BIM modeling to carry out corresponding mold design and processing; Step 5: After the first fixed brick mold is processed, the fixed brick mold is tested and the finished product accuracy and product qualification rate of the fixed brick mold are tested; Step 6. Before the formal construction on site, the finalized brick molds of each wall masonry and secondary structure concrete components are assembled and arranged as a whole, and construction can be carried out after verification and confirmation.

[0005] Furthermore, in the step 2, the axis, elevation, size, and position deviation of the main concrete structure of the building are first reviewed, and the positional relationship between the completed main structure and the secondary structure masonry, ring beam, and structural column is checked.

[0006] Preferably, in step three, the representative wall is a wall having only a ring beam but no structural column, or a wall having both a ring beam and a structural column, or a T-shaped wall, an L-shaped wall, or a cross wall.

[0007] Preferably, in step 4, the precision error of the shaping brick mold does not exceed 2 mm.

[0008] Preferably, in step five, the precision error of the finished brick mold does not exceed 3 mm.

[0009] Furthermore, in the step six, before formal masonry, first clean the base of the masonry wall, check the axis, elevation, position, and size of the wall, erect the skin number rod, and according to the secondary structure construction drawings after in-depth design, refer to the assembly methods of various types of walls and standardized brick molds in the typical wall standardized brick mold layout, and carry out the overall combination layout of wall masonry and standardized brick molds to ensure that the masonry method, mortar joints, and masonry lap length meet the requirements of design and construction specifications before masonry.

[0010] Furthermore, in step six, after the masonry mortar strength reaches the strength required by the design and construction specifications, the secondary structural concrete components are poured. When pouring concrete, each pouring height does not exceed 500mm, and steel bars are used to vibrate and compact it.

[0011] Furthermore, in step six, when building the wall, it is difficult to clean up the garbage at the structural column, and protective measures are taken at the holes of the shaped bricks to prevent mortar debris from falling into the structural column.

[0012] Furthermore, in step four, the shaped brick mold includes a steel plate template, a steel rectangular tube keel, a base, a clamp and a limit plate, the steel plate template is fixedly connected to the base, the steel rectangular tube keel is fixedly connected to the steel plate template, the steel plate template is equipped with the clamp, and the limit plate is fixedly installed between the steel plate template and the base.

[0013] Furthermore, in step five, before the shaped brick mold is cast and manufactured, cold-drawn steel bars are arranged in the mold.

The embodiments of the present invention are described in detail below in conjunction with the drawings: The following is combined with Figure 1-Figure 13 The present invention is described in further detail: like Figure 1-Figure 11 As shown, this embodiment discloses a method for constructing a secondary structure concrete component of a fixed brick mold based on modular design, comprising the following steps: Step 1: Deepen the design. According to the general description of the building and structural construction design, structural drawings, architectural drawings, and relevant requirements of the design and construction specifications, use CAD and BIM technology to deepen the design of the secondary structural concrete components of all floors of the building and enter them into the drawings to ensure the accuracy and operability of the deepening documents of the secondary structural concrete components; Step 2: Structural review. Before the formal construction of the secondary masonry structure, first review the axis, elevation, size, and position deviation of the main concrete structure of the building, check the positional relationship between the completed main structure and the secondary structure masonry, ring beam, and structural column to be built, and review the detailed design drawings in combination with the actual situation. For the positions where the relevant parameters between the main structure and the secondary structure are significantly different, timely adjustments should be made, and the design unit should be asked to confirm them. After verification and confirmation, the number of unit modules of secondary structural concrete components on each floor shall be counted and summarized; Step 3: Layout of typical wall fixed brick molds. According to the secondary structure detailed design drawings confirmed by the design unit, select representative walls, preferably: walls with only ring beams but no structural columns, walls with both ring beams and structural columns, T-shaped walls, L-shaped walls, and cross walls. Use BIM modeling to carry out the layout design of masonry and fixed brick mold combination; After the overall layout drawing is completed, the secondary structure concrete components are decomposed into unit modules; Step 4: Mould processing: According to the secondary structure concrete component unit module parameters decomposed from the typical wall brick mould layout, combined with the actual situation on site and the construction progress requirements, BIM modeling technology is used to design and process the mould to ensure the accuracy and reliability of the mould size and size parameters, and the mould precision error does not exceed 2mm; like Figure 12-13 As shown, the molded brick mold includes a steel plate template 1, a steel rectangular tube keel 2, a base 3 and a clamp 4. The steel plate template 1 has multiple groups, which are assembled and welded above the base 3. The inverted mold space formed by the steel plate template 1 matches the ring beam unit module. The steel rectangular tube keel 2 is fixedly welded to the outer wall of the steel plate template 1. After each steel plate template 1 is assembled, it is locked by the clamp 4. The clamp 4 is preferably: a fastening bolt; The fixed brick mold used in the ring beam unit module also includes a limit plate 5 installed between the steel plate template 1 and the base 3 to lock the positions of the steel plate template 1 and the base 3 to resist deformation caused by grouting impact; The standard brick mold used in the structural column unit module also includes a handle 6 installed in the steel plate template 1; Step 5: Making the final brick mold. After the first final brick mold is processed, the final brick mold is tested and the precision and qualified rate of the final brick mold are tested. The precision error of the final brick mold is no more than 3mm. In order to prevent the fixed brick mold from cracking and breaking, before pouring, the fixed brick mold is equipped with 4mm diameter cold-drawn steel bars to increase the crack resistance of the fixed brick mold; Step 6: Wall layout, masonry, and pouring of concrete components. Before formal masonry, first clean the masonry wall base, check the axis, elevation, position, and size of the wall, and set up the skin number pole. According to the secondary structure construction drawings after in-depth design, refer to the assembly methods of various types of walls and standardized brick molds in the typical wall standardized brick mold layout, and carry out the overall combination layout of wall masonry and standardized brick molds to ensure that the masonry method, mortar joints, and masonry overlap length meet the requirements of design and construction specifications. After checking and confirming that they are correct, masonry can be carried out; During the wall construction process, it is difficult to clean up the garbage at the structural column, and protective measures should be taken at the holes of the shaped bricks to prevent mortar debris from falling into the structural column; After the masonry mortar strength reaches the strength required by the design and construction specifications, the secondary structural concrete components can be poured. When pouring concrete, each pouring height shall not exceed 500mm, and steel rods shall be used to vibrate and compact it.
