[0033] The technical solution of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0034] In the description of the embodiments of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood by specific circumstances.

[0035] Reference Figure 1-2 , a super-thick concrete pavement casting formwork system, which includes: a channel steel member 1, an elevation plate 2, a height adjustment member 3, a reinforcing vertical rod 4 and a reinforcing diagonal rod 5. The channel steel member 1 is placed horizontally, and the groove is facing the side away from the casting area. Its web 1-1 serves as the side form of the casting area. During implementation, due to the limited width of a single channel steel member 1, multiple channel steel members 1 can be adaptively stacked in the height direction according to the elevation of the super-thick concrete pavement, and the wing plates 1-2 of adjacent channel steel members 1 are overlapped and fastened to obtain a casting side form with appropriate height; the reinforcing vertical rod 4 and the reinforcing diagonal rod 5 are arranged on one side of the wing plate 1-2 of the channel steel member 1, the reinforcing vertical rod 4 is vertically arranged and connected to the wing plate 1-2 of the channel steel member 1, and the bottom end is anchored in the foundation, and the reinforcing diagonal rod 5 is obliquely arranged, one end of which is connected to the wing plate 1-2 of the channel steel, and the other end is anchored in the foundation.

[0036] By adopting the above technical scheme, during the pouring construction of ultra-thick concrete pavement, the web 1-1 of the high-strength channel steel member 1 is used as the pouring side formwork, which can improve the side limiting effect on the ultra-thick concrete and improve the construction quality; and the number of channel steel members 1 and the position of the elevation plate 2 can be increased or decreased at any time according to the elevation of the concrete pavement, and the construction is convenient and fast, and the control of the pavement elevation is accurate; after the reinforcement vertical rods 4 and the reinforcement diagonal rods 5 are installed, a triangular stable support system is formed with the foundation. Compared with the traditional wooden square back ribs, the support firmness and stability are higher, which has a greater positive effect on the smooth construction and construction quality.

[0037] Since the channel steel member 1 is a metal component, it is usually difficult to separate it after the concrete is poured and solidified. Therefore, this embodiment also provides a release agent layer 6 on the web 1-1 of the channel steel member 1. The release material is sprayed, coated, or brushed to achieve isolation between the concrete and the channel steel member 1, which is beneficial to the demoulding process after the ultra-thick concrete pavement is solidified.

[0038] The height adjustment member 3 includes a high-strength nut 3-1 and an adjusting screw 3-2. The high-strength nut 3-1 is fixed to the topmost channel steel member 1. The adjusting screw 3-2 is screwed into the high-strength nut 3-1. The elevation plate 2 is arranged at the bottom end of the adjusting screw 3-2. By rotating the adjusting screw 3-2, the height of the elevation plate 2 can be changed. Before construction, the height of each elevation plate 2 is adjusted to be uniform and accurate, so as to provide accurate elevation indication during construction and pouring.

[0039] Since the road has a certain construction length, the elevation plates 2 should also be set continuously, or evenly distributed on the channel steel member 1 at intervals to save consumables under the premise of meeting the construction requirements. In some preferred implementation schemes, multiple elevation plates 2 and height adjustment members 3 can be set along the length direction of the channel steel member 1, and the spacing between adjacent elevation plates 2 is 4m to 8m, preferably 6m.

[0040] To facilitate material acquisition, production and installation, the part of the reinforcement vertical rod 4 extending out of the foundation is fixed to the channel steel member 1 by a high-strength nut 27. During implementation, several groups of high-strength nuts 27 are evenly distributed along the length direction of the channel steel member 1 at one end of the wing plate 1-2 of the channel steel member 1. In the vertical direction, at least two high-strength nuts 27 are provided in each group. The reinforcement vertical rod 4 is screwed to the high-strength nut 27, and its bottom end is anchored in the foundation to stably support the channel steel member 1.

[0041] The reinforcing diagonal rod 5 is installed through the annular clamp 8 arranged on the top of the topmost channel steel member 1. One end of the reinforcing diagonal rod 5 is inserted into the annular clamp 8 and locked, and the other end is provided with an anchor screw hole 5-6, and the anchor screw hole 5-6 is provided with an anchor screw 9. The anchor screw 9 fixes the end of the reinforcing diagonal rod 5 to the foundation.

[0042] In order to achieve stable support, the annular clamp 8 should be fixed on the channel steel member 1 at a constant angle. In order to adapt to the pouring construction at different elevations, the number of channel steel members 1 will also be appropriately increased or decreased. In order to increase the application range and support stability of this formwork system, the reinforcing diagonal rod 5 can be set to be retractable, that is, the length of the reinforcing diagonal rod 5 can be appropriately increased or decreased according to the height of the annular clamp 8, so as to firmly anchor its bottom end to the ground. For example: the reinforcing diagonal rod 5 is configured as a slide rail 5-1 and a slide bar 5-2 that are slidably connected and fixed by a locking member, a plurality of pin holes 5-3 are set on the slide rail 5-1, and a pin hole 2 5-4 that matches the pin hole 1 5-3 is set on the slide bar 5-2. The locking member can be a high-strength bolt 5-5 installed in the pin hole 1 5-3 and the pin hole 2 5-4. By changing the overlapping area of ​​the slide rail 5-1 and the slide bar 5-2, the total length of the reinforcing diagonal rod 5 can be adjusted, and its installation and adjustment are very convenient.

[0043] In order to facilitate material acquisition, the above-mentioned slide rail 5-1 and slide rod 5-2 can both be made of high-strength steel pipes commonly found on construction sites.

[0044] As mentioned above, during actual construction, it is necessary to increase or decrease the number of channel steel parts 1 according to different construction requirements, and the channel steel parts 1 need to be firmly connected. Therefore, during implementation, it is necessary to set a plurality of connecting holes 1-3 on the wing plate 1-2 of the channel steel part 1, and pass high-strength bolts 10 through the connecting holes 1-3 to connect and fasten adjacent channel steel parts 1.

[0045] During construction, it is necessary to save consumables as much as possible to reduce construction costs while ensuring the stability of the support. Therefore, the reinforcing vertical bars 4 and the reinforcing diagonal bars 5 can be alternately arranged along the length direction of the channel steel member 1. The spacing between adjacent reinforcing vertical bars 4 and reinforcing diagonal bars 5 is 400mm to 600mm, preferably 500mm.

[0046] Compared with the prior art, the beneficial effects of the utility model are as follows: when pouring ultra-thick concrete pavement, the web 1-1 of the high-strength channel steel member 1 is used as the pouring side formwork, which can improve the side limiting effect on the ultra-thick concrete and improve the construction quality; and the number of channel steel members 1 and the position of the elevation plate 2 can be increased or decreased at any time according to the elevation of the concrete pavement, and the construction is convenient and fast, and the control of the pavement elevation is accurate; after the reinforcement vertical rods 4 and the reinforcement diagonal rods 5 are installed, a triangular stable support system is formed with the foundation. Compared with the traditional wooden square back ribs, the support firmness and stability are higher, which has a greater positive effect on the smooth construction and construction quality.

[0047] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
