For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] As described in the background technology, to ensure the formation of structural joints, foam boards and extruded polystyrene boards are usually used for caulking in the prior art, or a segmented construction method is used. However, the inventors have found that the method of using foam boards and extruded polystyrene boards for caulking has the following disadvantages: the purchase cost of using all foam boards and extruded polystyrene boards for caulking is high; when pouring concrete into the mold, the foam boards and extruded polystyrene boards are easily damaged by impact, causing the boards to be sandwiched in the cast-in-place concrete, reducing the strength of the main structure concrete; workers are prone to uneven material feeding on both sides during the concrete pouring process, resulting in a large difference in the deadweight of the concrete on both sides, and the boards are squeezed, resulting in the concrete structure on the other side without a protective layer, etc. The segmented construction method has the following disadvantages: the use of segmented flow construction affects the construction period; the risk of falling from a height is greater when constructing near the edge; if edge protection is used, the cost will increase, etc.

[0044] That is, the method of using foam boards and extruded polystyrene boards for filling or segmented construction has technical problems such as high production cost, poor quality, impact on construction period and low safety.

[0045] Based on this, please refer to Figure 1-Figure 4 The embodiment of the utility model provides a structural seam template 100, which can effectively improve the above-mentioned technical problems, that is, it can reduce production costs, save construction time, improve the quality of structural seam forming, and has high construction safety.

[0046] It should be noted that the first direction in the following content is Figure 1-Figure 4 The X direction is shown in Figure 1-Figure 4 The Y direction is shown in the figure, and the third direction is Figure 1-Figure 4 The structural seam template 100 will be described in detail below.

The first inner template 21 is arranged on one side of the frame 10, and the second inner template 22 is relatively arranged on the other side of the frame 10. The first outer template 31 is arranged at intervals on the side of the first inner template 21 away from the frame 10 to form a first concrete pouring space 41, and the second outer template 32 is arranged at intervals on the side of the second inner template 22 away from the frame 10 to form a second concrete pouring space 42. By pouring concrete 200 into the first concrete pouring space 41 and the second concrete pouring space 42, after the pouring is completed, the structural joint template 100 can be taken out by relying on the gap generated by the shrinkage of the concrete 200 itself, so that the gap between the two concretes 200 is the formed structural joint 300.

[0048] That is to say, the skeleton 10 can play a supporting role in the process of pouring concrete, and cooperate with the first inner formwork 21 and the second inner formwork 22 to form a filling structure. Compared with the existing method of using foam boards and extruded polystyrene boards for filling, it can save material costs; at the same time, through the cooperation of the first inner formwork 21 and the first outer formwork 31, and the cooperation of the second inner formwork 22 and the second outer formwork 32, the structural joint 300 formed by pouring concrete has good appearance molding quality and avoids the quality risk of slag inclusion in the main structure; and the use of the structural joint formwork 100 can be carried out in parallel on the same floor. Compared with the segmented construction method, it can save implementation time. At the same time, there is no edge operation, which avoids the risk of falling from height and improves construction safety.

[0049] It should be noted that, in order to better separate the structural joint formwork 100 from the cast concrete 200 , an isolation agent may be applied to the first inner formwork 21 , the second inner formwork 22 , the first outer formwork 31 and the second outer formwork 32 .

[0050] Specifically, please refer to Figure 2 , Figure 2 The schematic diagram of the structure of the skeleton 10 provided in this embodiment, combined with Figure 1 and Figure 2The skeleton 10 includes a first support frame 11, a second support frame 12 and a plurality of inner support bars 13. The first support frame 11 and the second support frame 12 are arranged at intervals, and the plurality of inner support bars 13 are arranged at intervals. Each inner support bar 13 is connected to the first support frame 11 and the second support frame 12 at the same time. The first inner template 21 is arranged on the side of the first support frame 11 away from the second support frame 12, and the second inner template 22 is arranged on the side of the second support frame 12 away from the first support frame 11. In other words, the first inner template 21 is fixed on the outer side of the first support frame 11, and the second inner template 22 is fixed on the outer side of the second support frame 12, and then the first support frame 11 and the second support frame 12 are firmly connected by the plurality of inner support bars 13, thereby forming a high-strength caulking structure.

[0051] Further, in the present embodiment, the first support frame 11 includes a plurality of first horizontal bars 111 and a plurality of first vertical bars 112, the second support frame 12 includes a plurality of second horizontal bars 121 and a plurality of second vertical bars 122, the plurality of first horizontal bars 111 and the plurality of second horizontal bars 121 are arranged at intervals and correspond one to one along the first direction, the plurality of first vertical bars 112 and the plurality of second vertical bars 122 are arranged at intervals and correspond one to one along the first direction; the plurality of first vertical bars 112 and the plurality of second vertical bars 122 are arranged at intervals along the second direction, the plurality of first horizontal bars 111 and the plurality of second horizontal bars 121 are arranged at intervals along the third direction, one end of each inner support bar 13 is connected to the first horizontal bar 111 and the first vertical bar 112 at the same time, and the other end is connected to the second horizontal bar 121 and the second vertical bar 122 at the same time; wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0052] like Figure 2 As shown, in this embodiment, through the mutual connection and cooperation of multiple first vertical bars 112, multiple second vertical bars 122, multiple first horizontal bars 111, multiple second horizontal bars 121 and multiple inner support bars 13, a structure in which multiple small rectangular brackets are arranged in a matrix can be formed. Compared with filling the seams entirely with foam boards or extruded polystyrene boards, production costs are saved, and the internal structures of the skeleton 10 interact with each other, have higher strength, and can form a structural seam 300 of better quality.

[0053] In order to better connect the first inner template 21, the second inner template 22 and the frame 10, please refer to Figure 3 and Figure 4 , Figure 3 A cross-sectional view of the structural seam template 100 provided in this embodiment in a first direction, Figure 4 The cross-sectional view of the structural seam template 100 provided in this embodiment in the second direction, combined with Figure 3 and Figure 4The structural seam template 100 also includes a connecting piece 51 , and the first inner template 21 and the second inner template 22 are both connected to the frame 10 via the connecting piece 51 .

The first inner formwork 21, the third inner formwork 23, the second inner formwork 22 and the fourth inner formwork 24 are sequentially arranged around the skeleton 10; the top formwork 25 is arranged on the top surface of the skeleton 10, and the bottom formwork 26 is arranged on the bottom surface of the skeleton 10.

[0056] It is easy to understand that in this embodiment, the first inner template 21, the second inner template 22, the third inner template 23, the fourth inner template 24, the top template 25 and the bottom template 26 are all connected to the frame 10 by screws.

[0057] Please combine Figure 1 and Figure 3 During the installation of the structural seam formwork 100 and the pouring of the concrete 200, in order to facilitate the staff to check the elevation, in this embodiment, the top height of the skeleton 10 is higher than the top surfaces of the first outer formwork 31 and the second outer formwork 32; the top height of the first inner formwork 21 is higher than the top surfaces of the first outer formwork 31 and the second outer formwork 32; the top height of the second inner formwork 22 is higher than the top surfaces of the first outer formwork 31 and the second outer formwork 32.

The first fixing tube 66 is arranged between the first clip 64 and the first outer template 31. The first nut 62 is sleeved on the screw rod 61 and is located on the side of the first clip 64 away from the first fixing tube 66, so as to fix the first clip 64 and the first fixing tube 66 to the first outer template 31; similarly, the second clip 65 is sleeved on the screw rod 61 and is located on the side of the second outer template 32 away from the second inner template 22.

Of course, in other embodiments, the above structure can also be made of other materials such as plastic.

[0065] Through the above description, this embodiment also provides a method for preparing a structural seam template 100, and the preparation method specifically includes:

[0066] Step S10: Use wooden beams to make a skeleton 10, the height of the skeleton 10 is: the height of the concrete 200 + 200mm, the width of the skeleton 10 is: the width of the structural joint 300 - 15mm*2 (15mm is the thickness of the first inner formwork 21 and the second inner formwork 22); the length of the skeleton 10 is: the length of the structural joint 300 - 15mm*2 (15mm is the thickness of the third inner formwork 23 and the fourth inner formwork 24); the spacing between the multiple first vertical bars 112, the second vertical bars 122, the first horizontal bars 111 and the second horizontal bars 121 is 250mm, and the spacing between the multiple inner support bars 13 is 500mm.

[0069] Step S40: Connect the lifting ring 52 to the first inner formwork 21, the second inner formwork 22 and the frame 10, and connect the lifting ring 52 to the tower crane to transport the caulking structure to a designated location.

[0070] Step S50: Assemble the first fixing plate 71 and the first outer formwork 31 , and separate them from the first inner formwork 21 to form a first concrete pouring space 41 ; assemble the second fixing plate 72 and the second outer formwork 32 , and separate them from the second inner formwork 22 to form a second concrete pouring space 42 .

[0071] Step S60: Drill holes in the first fixed plate 71, the first outer template 31, the first inner template 21, the second inner template 22, the second outer template 32 and the second fixed plate 72, and pass the pipe sleeve 68 through the drilled holes in sequence through the first fixed plate 71, the first outer template 31, the first inner template 21, the frame 10, the second inner template 22, the second outer template 32 and the second fixed plate 72.
