Traditional building flower bed molds are mostly one-time use of wooden templates manually on site, which consumes wood and labor, has high costs, low work efficiency, and there are certain construction risks in high-altitude operations. On the other hand, as a component for planting plants cantilevered outside the building, the flower bed has high requirements for waterproofness while ensuring structural stability. At present, various flower beds require additional complex processes to ensure waterproofness after assembly. Summary of the invention

[0027] like Figure 1 As shown, the construction method of the embedded flower bed disclosed in this embodiment has the following specific steps:

[0028] Step 1: reserve a flower bed hole on the building base. The flower bed hole is a rectangular hole with grooves on both sides of the hole wall for embedding connecting steel bars.

[0029] Step 2: Prefabricate the flower bed in the factory. Prefabrication requires the use of prefabricated molds. Figure 1 As shown, the prefabricated mold includes an outer mold 1, an inner mold 2 and a connecting cantilever 3; the inner mold 2 is placed inside the outer mold 1, and the top surface is connected to the top surface of the outer mold through the connecting cantilever 3 to form a mold cavity, and then concrete is poured into the mold cavity, and the mold is demoulded after curing. Figure 2 As shown, the completed flower bed 4 includes a flower bed body 41 and a lap beam 42, and a connecting steel bar 43 extends out from the outer end of the lap beam to improve the casting effect with the building base.

[0030] At the same time, in order to facilitate assembly and demoulding, the outer mold 1, the inner mold 2 and the connecting cantilever 3 are designed to be assembled.

[0031] Figure 3As shown, the outer mold 1 includes an inner rib 11, an outer rib 12, a corner rib 13 and a main reinforcement fixing baffle 14. The outer rib 11 and the inner rib 12 have the same structure and are both rectangular frames, one side of which is open in the length direction, and a number of vertical ribs are arranged therein, and a mounting hole is provided on the top surface. The corner rib 12 is an L-shaped rib, including two sections, and the length of one end is equal to the length difference between the outer rib and the inner rib. The main reinforcement fixing baffle 14 is a rectangular plate. During assembly, the outer rib and the inner rib are arranged in parallel, a pair of corner ribs are arranged at both ends of the outer rib, and the other end is connected to the main reinforcement fixing baffle, and the other end of the main reinforcement fixing baffle is connected to the inner rib. The corner rib makes up for the length difference between the inner rib and the outer rib, and a strip area is formed between the corner rib and the inner rib. During pouring, the connecting steel bars are pre-buried in the strip area, and the outer end of the leveling steel bar extends to the outside of the main reinforcement fixing baffle, so that a lap beam 42 is formed in the strip area. The main body area surrounded by the other side of the corner rib, the outer rib and the inner rib is used to install the inner mold 2 so as to form a mold cavity for pouring the flower bed main body 41.

[0032] like Figure 4 As shown, the inner mold 2 is a rectangular mold, including a long baffle plate 21 of the sinking platform, a short baffle plate 22 of the sinking platform and a connecting plate 23; the long baffle plate 21 of the sinking platform is L-shaped, including a long side and a short side, and the outer end faces of the long side and the short side are both inclined surfaces; the corner baffle plate 22 of the sinking platform is an L-shaped plate, including two short sides, and the outer end faces of the two short sides are both inclined surfaces; the connecting plate 23 is a rectangular plate, which is provided with a plurality of assembly holes. During assembly. The two corner baffle plates of the sinking platform are arranged at the two ends of the same diagonal line of the inner mold, and are detachably connected between the two long baffle plates of the sinking platform, and the connecting plate is connected to the top surface of the long side of the long baffle plate of the sinking platform. Since the joint surface of the long baffle plate and the short baffle plate of the sinking platform is an inclined surface, it is convenient to remove the mold, and when removing the mold, a diagonal splicing scheme is adopted, the short baffle plates of the sinking platform at both ends of the diagonal line can be demolded first, and then the long baffle plates of the sinking platform are removed to further improve the convenience of demolding, facilitate assembly, and different lengths of long baffle plates of the sinking platform can be selected according to the use requirements of different lengths, which is conducive to improving versatility and realizing modularization. After the inner mold 2 is assembled, it is placed in the mold cavity of the outer mold 1, and is detachably connected by connecting the cantilever 3 to enclose a casting cavity.

[0033] like Figure 5 As shown, the connecting cantilever 3 includes a crossbeam 31, an outer pole 32, an inner pole 33 and a bottom plate 34; a pair of outer poles are arranged at both ends of the crossbeam in a door shape; the inner pole is connected to the lower middle part of the crossbeam; a connecting hole is arranged on the bottom plate, and each bottom plate is arranged at the bottom of the outer pole and the inner pole; the connecting cantilever is connected to the outer mold through the bottom plate under the outer pole, and is connected to the inner mold through the bottom under the inner pole. The connection between the inner mold and the outer mold adopts a cantilever process, and the mold can be removed after the concrete reaches the strength, and the prefabricated flower bed can be obtained by curing. The flower bed is directly poured with concrete at one time, which can meet the strength requirements while ensuring waterproof performance.

[0034] Step 3: Place the prefabricated flower bed into the hole of the flower bed.

[0035] Step 4: Pour concrete on the assembly surface of the flower bed and the flower bed hole to cover the connecting steel bars to form a whole. Since it is an embedded integrated flower bed, both sides are cast in situ to form a whole, which has reliable safety performance and can be used in high-rise buildings.

[0036] Compared with traditional construction methods, this method does not require on-site mold making during construction, which reduces the intensity of work, improves work safety and construction efficiency, and shortens the construction period. In addition, the mold can be reused, which can save materials. On the other hand, after the construction is completed, the flower bed is embedded in the building matrix to form a whole, which has reliable safety performance and can be used in high-rise buildings.
