DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0034] As Figures 1-4As shown, this invention provides the following technical solution to solve the problem of unstable and rapid installation of concrete pouring formwork for parapet walls on pitched roofs: a formwork system for parapet walls on pitched roofs, including a bottom formwork frame, a main formwork frame, and an upper suspended formwork frame. The main formwork frame is located on one side of the bottom formwork frame, and the upper suspended formwork frame is located above the bottom formwork frame and connected to the upper end of the main formwork frame. The bottom formwork frame includes a support base 1 and several bottom formwork templates 2 installed on the upper end of the support base 1. The main formwork frame includes at least two parallel vertically arranged main rods 3 and connecting crossbars for connecting the main rods 3. The upper suspended formwork frame includes horizontal suspension rods 4 connected to the upper ends of the corresponding main rods 3 and inclined suspension rods 7 connected to the corresponding horizontal suspension rods 4. The inclined suspension rods 7 and horizontal suspension rods 4 are arranged in a cross configuration, and limiting crossbars 5 and 6 are installed at two opposite included angles. The inclined suspension rods 7 extend above the bottom formwork templates 2, and several upper formwork templates 9 are connected to the lower side of the inclined suspension rods 7 through several suction devices 8.

[0035] Specifically, the bottom formwork, main formwork, and upper suspended formwork are all assembled on-site. The bottom formwork 2 and upper formwork 9 are ordinary concrete pouring formwork, and their dimensions can be adjusted according to the dimensions of the parapet wall of the sloping roof. The spacing of the main support rods 3 can also be adjusted according to the length of the bottom formwork 2 and upper formwork 9; generally, the spacing of the main support rods 3 should be slightly smaller than the length of the bottom formwork 2 and upper formwork 9. Meanwhile, the angle of the inclined suspension rods 7 can be adjusted by the position of the limiting crossbars 5 and 6 to meet the requirements of pouring concrete of different thicknesses.

[0036] The support base 1 is assembled from steel pipes, which can serve as columns or beams. The support base 1 is formed by crisscrossing the steel pipes. The bottom formwork 2 needs to be installed on the surface of the support base 1. The suction device 8 keeps the upper formwork 9 suspended in the air, and corresponding reinforcing bars can be placed between the upper formwork 9 and the bottom formwork 2 before pouring concrete to form the parapet wall.

[0037] In this embodiment, as Figure 1 As shown, the main support rod 3 includes an upper main support rod 36 and a lower main support rod 32 arranged axially. The upper main support rod 36 and the lower main support rod 32 can slide axially. A locking component 35 is provided between the upper main support rod 36 and the lower main support rod 32. The relative axial movement between the upper main support rod 36 and the lower main support rod 32 can adjust the height of the entire main support rod 3. The locking component 35 can take various forms, such as locking screws or positioning pins arranged radially along the upper main support rod 36 and the lower main support rod 32, or it can be a locking nut arranged axially. The axial movement of the locking nut tightens the end of the upper main support rod 36 or the lower main support rod 32, thereby locking the upper main support rod 36 and the lower main support rod 32.

[0038] To ensure the stable placement of the main rod 3, the main rod 3 also includes a bottom plate 31 at the lower end, and the upper side of the bottom plate 31 is connected to the lower main rod 32 by several diagonal braces 33.

Both the upper connecting crossbar 37 and the lower connecting crossbar 34 are connected to the main support bar 3 through a fastener 10. The fastener 10 can be a commonly used connecting fastener for construction scaffolding. Its structure is existing technology and will not be described in detail here.

The connection position between the horizontal suspension rod 4 and the inclined suspension rod 7 is fixed. The tilt angle of the inclined suspension rod 7 can be adjusted by the position of the limiting crossbars 5 and 6 on the horizontal suspension rod 4.

[0041] In this embodiment, as Figure 4 As shown, the suction device 8 includes a suction cup 81 and a connector 84 installed at the tail of the suction cup 81. The connector 84 is connected to the inclined suspension rod 7. A control air valve 82 is installed on the suction cup 81, and a suction cup fine adjuster 83 for adjusting the length of the connector 84 is installed on the connector 84. The control air valve 82 can be connected to an external negative pressure suction device, such as an air pump or air cylinder, to extract the air from the contact surface between the suction cup 81 and the upper template 9, so that the suction cup 81 firmly adheres to the upper template 9. If the control air valve 82 releases air, the suction cup 81 and the upper template 9 can be separated.

[0042] The suction cup adjuster 83 can be a threaded sleeve. By rotating the threaded sleeve, the connector 84 can be extended or retracted, thus adjusting the length of the connector 84.
