[0002] In the existing technology, steep slope roofs are widely used in various types of buildings. The existing slope roof construction usually adopts two methods, one is the manual compaction method to pour concrete, and the other is the double-sided formwork method. During the construction of the former, although the construction cost can be guaranteed, the density of the concrete is difficult to control, and it is easy to have the phenomenon of rough surface and exposed reinforcement, which leads to quality risks such as roof leakage; the latter has a higher construction cost, and the formwork needs to be opened in many places, and then concrete pads are used to ensure the cross-sectional size. Not only is the labor and material cost high, the construction process is cumbersome, and multiple openings are prone to leakage risks in the later stage. If the concrete is not vibrated in place, it is easy to have quality problems such as honeycombs and holes. There are technical problems such as the density of concrete is difficult to control, the positioning and installation process of the formwork is cumbersome, the construction cost is high, and there are quality risks due to multiple openings or inadequate vibration.

[0030] Embodiment 1:

[0031] like Figures 1 to 4 As shown, a schematic diagram of an embodiment of a sloping roof concrete pouring positioning device of the present invention includes a sloping roof formwork structure arranged above a wall 1, the sloping roof formwork structure includes a bottom formwork 2 and a top formwork 3, the bottom formwork 2 is connected to the wall 1, a pouring space 10 is formed between the top formwork 3 and the bottom formwork 2, and also includes a connecting member and a positioning member, the top formwork 3 is rotatably connected to the wall 1 through the connecting member, and the positioning member is arranged between the wall 1 and the top formwork 3 to limit the inclination angle of the top formwork 3. The wall 1 in this embodiment can be a fixed wall that has been completed, and can also generally refer to a wall formwork used for the construction of the wall 1.

[0032] In this embodiment, the connecting member includes a vertical plate 4 connected to the wall 1 and a supporting plate 5 connected to the top formwork 3 , and the vertical plate 4 is rotatably connected to the supporting plate 5 .

[0033] In this embodiment, the vertical plate 4 is installed outside the wall 1 so that it can be disassembled after concrete pouring. The vertical plate 4 has a mounting hole 41 and is fixed to the wall 1 by embedded bolts. The support plate 5 has a fixing hole 51 and is fixed to the top template 3 by screws. The vertical plate 4 and the support plate 5 are rotatably connected by a hinge assembly, and the hinge assembly includes a rotating shaft 8 and a rotating sleeve 9. In this embodiment, the rotating shaft 8 is connected to the vertical plate 4, and the rotating sleeve 9 is sleeved outside the rotating shaft 8 and connected to the support plate 5; in other embodiments, the rotating shaft 8 can also be connected to the support plate 5, and the rotating sleeve 9 is sleeved outside the rotating shaft 8 and connected to the vertical plate 4.

[0034] In this embodiment, the positioning member includes a diagonal brace 6 , one end of which is connected to the vertical plate 4 , and the other end of which is used to limit the inclination angle of the top formwork 3 .

[0035] On the other hand, the present invention also provides a construction method of a sloping roof concrete pouring positioning device, comprising the following steps:

[0036] After the top formwork 3, the bottom formwork 2, the connecting members and the positioning members are installed with each other, concrete is poured from the gap between the top formwork 3 and the bottom formwork 2, that is, concrete is poured in the pouring space 10. Before pouring, an overhead support 7 can be preset in the pouring space 10 to temporarily carry the top formwork 3. The concrete gradually rises in the pouring space 10, and the top formwork 3 is driven to rotate as the concrete is filled. The end of the top formwork 3 close to the diagonal support 6 is gradually pressed down. When the top formwork 3 abuts against the diagonal support 6, the top formwork 3 stops rotating and is parallel to the bottom formwork 2. Concrete with a larger slump can be used to reduce the requirements for vibration.

[0037] Concrete may also be vibrated through the top formwork 3 for reinforcement.

[0038] This embodiment realizes the rotation connection between the bottom formwork 2 and the top formwork 3 through the connecting member, and uses the poured concrete to drive the top formwork 3 to rotate. When the top formwork 3 is parallel to the bottom formwork 2 through the diagonal brace 6, the rotation stops due to the abutment against the diagonal brace 6, thereby controlling the thickness of the concrete pouring of the inclined roof, ensuring the uniformity of the concrete pouring thickness, and having a simple structure, and can also improve the construction quality. This embodiment can utilize the fluidity of concrete to make it flow from top to bottom along the inclined bottom formwork 2 for filling, and can reduce the vibration requirements through gravity. At the same time, a vibrator can also be used in combination to vibrate through the top formwork 3 to reduce the quality risks of honeycombs, exposed reinforcement, etc. in the concrete.

[0039] Embodiment 2:

[0040] like Figure 5As shown, in this embodiment, the diagonal brace 6 can be extended and adjusted. By adjusting the length of the diagonal brace 6, different inclination angles of the top formwork 3 can be limited, so that it can meet the construction requirements of roof concrete pouring with different slopes, so that the concrete poured on the bottom formwork 2 with different slopes can ensure uniform thickness.

[0041] In this embodiment, the diagonal brace 6 includes an outer rod and an inner rod disposed inside the outer rod, the inner rod is connected to the vertical plate 4 and has a plurality of telescopic holes, the outer rod has a limit hole, the limit hole corresponds to at least one telescopic hole and is fixed by a fastening bolt. It can be understood that the telescopic method of the diagonal brace 6 can be used as long as it can meet the telescopic function, and the specific structure can be flexibly selected based on the common technical knowledge of those skilled in the art, such as a structure of a sliding rod, a sliding sleeve and a locking member, or a structure in which a hole is opened in the sliding rod or the sliding sleeve and a fixing member is inserted through the corresponding hole, or an electric telescopic rod, etc.

[0042] Embodiment 3:

[0043] like Figure 6 As shown, in this embodiment, the diagonal brace 6 is movably connected to the vertical plate 4 to be adjusted to be suitable for the construction of roofs with different slopes.

[0044] In different embodiments, the diagonal brace 6 can be freely selected and matched in the following ways: sliding connection with the vertical plate 4; rotation connection with the vertical plate 4; telescopic connection of the diagonal brace 6; etc., to achieve flexible positioning to meet the construction requirements of roofs with different slopes.

[0045] In this embodiment, the diagonal brace 6 is slidably connected to the vertical plate 4 and the diagonal brace 6 is rotatably connected to the vertical plate 4. The manner of sliding connection or rotatably connection between the diagonal brace 6 and the vertical plate 4 and its specific structure can be flexibly selected based on the common technical knowledge of those skilled in the art.

[0046] In this embodiment, the diagonal brace 6 includes an abutment tube and an adjusting screw. One end of the adjusting screw is connected to the vertical plate 4 , and the other end is connected to the inner thread of the abutment tube to adjust the length of the diagonal brace 6 .

[0047] In this embodiment, the diagonal brace 6 is slidably connected to the vertical plate 4 through a movable sleeve 11. The vertical plate 4 has multiple movable holes evenly distributed along its length direction. The movable sleeve 11 is sleeved on the outside of the vertical plate 4 and has positioning holes corresponding to the movable holes. The positioning holes can correspond to the corresponding movable holes and are fixed by positioning bolts and positioning nuts.

[0048] In this embodiment, the diagonal brace 6 is rotatably connected to the vertical plate 4 through a clip assembly, and the clip assembly includes a first clip, a second clip, a rotating shaft and a plurality of locking nuts. The first clip and the second clip are both connected to the movable sleeve 11, and the diagonal brace 6 is rotatably arranged between the first clip and the second clip. The rotating shaft passes through the first clip, the diagonal brace 6 and the second clip in sequence and is threadedly connected to at least one locking nut at both ends for fastening.

[0049] In this embodiment, there is no need to change the position of the embedded bolts on the wall 1. Not only can the vertical plate 4 be fixed directly through the embedded bolts and the mounting holes 41, but also, according to the construction requirements of roofs with different slopes, the diagonal braces 6 can be slid or rotated relative to the vertical plate 4 for preliminary adjustment to locate the maximum inclination angle of the top template 3, thereby avoiding multiple holes on the wall 1 and ensuring the quality of the wall 1. According to the construction situation, fine-tuning can be performed by rotating the abutment tube to achieve precise positioning.
