[0002] With the advancement of new building industrialization, traditional construction methods are no longer able to adapt to current development requirements due to problems such as long construction period, difficult to ensure quality, and large pollution on the construction site. Modular construction is a form of construction that is prefabricated in the factory and transported to the site for assembly. Compared with traditional structural forms, modular structures have the advantages of high construction efficiency, high degree of standardization, labor saving, low carbon and environmental protection, safety and reliability, etc., and have shown great development potential in the context of new building industrialization.

[0003] Due to the different building requirements, structural needs, and application scenarios, the key issue of modular construction methods is to develop prefabricated components that are easy to connect, flexible in design, and have good overall performance.

The steel bars in the shear wall are densely reinforced, and the on-site construction has a large workload and difficulty in steel bar binding. The on-site formwork is difficult to support and dismantle, and the construction period is too long, resulting in high winter construction costs for concrete pouring and maintenance. Therefore, it is necessary to develop new high-performance shear wall structures and modular design and construction technologies with good stress performance and fast construction.

[0026] The UHPC formwork-honeycomb steel concrete composite structure wall based on modular construction has a simple structure. The design of the composite structure wall can be adjusted according to the building requirements, structural requirements, and application scenarios, and has the advantage of flexible design. The prefabricated UHPC formwork serves as both a load-bearing element and a casting formwork, solving the problem of difficulty in on-site formwork support and dismantling.

After reasonable optimization, the material cost can be the same as or even lower than that of the reinforced concrete solution. Considering the construction cost and the shortened construction period, it has good economic benefits.

[0031] In general, a UHPC formwork-honeycomb steel-concrete composite structure wall based on modular construction combines the characteristics of steel-concrete structure and prefabricated composite structure.

The width of the composite structure wall can be adjusted according to building requirements, structural requirements, and application scenarios, and has the advantage of flexible design. The honeycomb H-shaped steel is set inside the UHPC formwork, which can effectively reduce the area of ​​steel bars, reduce the workload of steel bar binding, shorten the construction period, and also enhance the deformation capacity and energy consumption capacity of the wall under earthquake action. The components are connected by bolts, which is convenient to construct and reliable, and has broad prospects for engineering applications. BRIEF DESCRIPTION OF THE DRAWINGS

The honeycomb H-shaped steel 2, the steel cage 3 and the cast-in-place concrete 4 are all located inside the prefabricated UHPC formwork 1. Among them, the prefabricated UHPC formwork 1, the honeycomb H-shaped steel 2 and the steel cage 3 are factory prefabricated parts, and the cast-in-place concrete 4 is a site-cast part.

The vertical steel bars 14 are tied to the horizontal steel bars 13 and can be arranged throughout the length of the prefabricated UHPC formwork 1.

[0051] The present invention adopts high-strength bolts 5 to ensure good connection effect and wall performance. In some embodiments, the high-strength bolts 5 can also be replaced by rivet bolts, single-side bolts, etc. of the same specifications.

[0052] The cast-in-place concrete 4 of the present invention can be selected according to the engineering requirements, for example, it can be ordinary concrete, high-strength concrete, self-compacting concrete, recycled concrete or radiation-proof concrete.

[0053] As mentioned above, the prefabricated UHPC formwork 1 of the present invention can be designed into various shapes. In order to facilitate assembly, the present invention designs several template units, such as Figure 4 , Figure 5 and Figure 6 As shown, they are rectangular UHPC templates 6, U-shaped UHPC templates 7 and L-shaped UHPC templates 15. The prefabricated UHPC formwork 1 can be composed of a plurality of U-shaped UHPC templates 7 and a plurality of rectangular UHPC templates 6, or can be composed of a plurality of U-shaped UHPC templates 7, a plurality of rectangular UHPC templates 6 and a plurality of L-shaped UHPC templates 15. Preferably, the honeycomb H-shaped steel 2 of the present invention is used to be arranged at the joints of adjacent templates, and the adjacent templates are connected by high-strength bolts 5. Further preferably, the joints of adjacent templates correspond to the webs of the honeycomb H-shaped steel 2, and the high-strength bolts 5 pass through the flange plate 9 and the template to connect the adjacent templates to the honeycomb H-shaped steel 2.

The first rectangular plate and the third rectangular plate are located on the same side of the second rectangular plate, and the two are parallel and have equal areas. The side of the first rectangular plate and the third rectangular plate away from the second rectangular plate is the splicing side, and reserved holes 8 are evenly arranged along the height direction on the splicing side, and its height direction is the height direction of the wall.

[0056] like Figure 6 As shown, the L-shaped UHPC template 15 is composed of two rectangular plates, the plate thickness is 20-50mm, and the top view shape is "L-shaped", and one side of the first rectangular plate is connected to one side of the second rectangular plate, and preferably connected vertically.

[0057] The above-mentioned reserved hole 1 8 corresponds to the reserved hole 2 12 on the flange plate 9 of the honeycomb H-shaped steel 2, and the high-strength bolt 5 passes through the reserved hole 1 8 and the reserved hole 2 12, that is, the connection between the corresponding template and the honeycomb H-shaped steel 2 is realized. That is, the adjacent templates are connected by the flange plate 9 of the honeycomb H-shaped steel 2, and the upper and lower flange plates 9 of the honeycomb H-shaped steel 2 are connected to the adjacent templates, so that the honeycomb H-shaped steel 2 is fully supported in the prefabricated UHPC formwork 1.

The high-strength bolts 5 pass through the reserved holes 1 8 and the reserved holes 2 12 to connect one flange plate 9 of the honeycomb H-shaped steel 2 to the U-shaped UHPC template 7 and the rectangular UHPC template 6. Obviously, on the other splicing side of the U-shaped UHPC template 7, high-strength bolts 5 are also used to pass through the reserved holes 1 8 and the reserved holes 2 12 to connect the other flange plate 9 of the honeycomb H-shaped steel 2 to another rectangular UHPC template 6.

On each splicing side, the high-strength bolt 5 passes through the reserved hole 1 8 and the reserved hole 2 12 to connect the corresponding templates.

[0060] Furthermore, in this embodiment, the two honeycomb H-shaped steels 2 near the corners can be replaced with honeycomb T-shaped steels 16. In this case, the size of the L-shaped UHPC template 15 at the outer corner is small, while the size of the L-shaped UHPC template 15 at the inner corner is large.

In order to improve the strength at the node, a full-length reinforcing steel pipe 17 can be set in the middle of the cross-shaped cavity.

[0062] Furthermore, the prefabricated UHPC formwork 1 of the present invention can also be a T-shaped cavity structure, that is, the top view is a "T-shaped frame", thereby forming a T-shaped wall. It is composed of three U-shaped UHPC templates 7 located at three ends, two L-shaped UHPC templates 15 located at the corners, and several rectangular UHPC templates 6 located between the corners and the ends and between the ends. On each splicing side, high-strength bolts 5 pass through the reserved hole 1 8 and the reserved hole 2 12 to connect the corresponding templates. In order to improve the strength at the node, a full-length reinforcing steel pipe 17 can be set at the corner of the T-shaped cavity structure.
