Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0015] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See also Figure 1 and Figure 2 As shown, a concrete protective door involved in this embodiment includes an inner plate 1 and an outer plate 2 matched with the inner plate 1, a ring frame 3 close to the edge is connected between the outer plate 2 and the inner plate 1, a pouring port 4 is opened on the outer plate 2, and a plurality of main partition ribs 5 extending radially and arranged between the inner plate 1 and the outer plate 2 are arranged on the outer periphery of the pouring port 4, one end of the main partition rib 5 is close to the pouring port 4, and the other end extends to the ring frame 3, and a concrete partition chamber 6 arranged between the inner plate 1 and the outer plate 2 is formed between two adjacent main partition ribs 5, one end of the concrete partition chamber 6 is connected to the pouring port 4, and the other end is closed by the ring frame 3, and the end of the concrete partition chamber 6 away from the pouring port 4 is provided with a balancing port 7 opened on the outer plate 2.

[0018] Furthermore, the pouring port 4 is provided with a pouring neck (not shown) connected to the outer plate 2 , and a flange 9 is provided on the pouring neck.

[0019] Furthermore, the interval angles between two adjacent main partition ribs 5 are equal.

[0020] In this embodiment, the mixed concrete is poured into the pouring port 4. Since the pouring port 4 is connected to all the concrete sub-cavities 6, all the concrete sub-cavities 6 can be filled during the continuous pouring process. The balance port 7 is provided to discharge excess gas and to determine that the concrete sub-cavities 6 are filled when the concrete overflows.

[0021] Example 2

[0022] See also Figure 1 and Figure 2 As shown, the concrete protective door involved in this embodiment is further configured on the basis of Embodiment 1, wherein a supporting partition rib 8 connected to the main partition rib 5 is provided in the concrete chamber 6 .

[0025] In this embodiment, both the main partition ribs 5 and the branch partition ribs 8 can be used to connect the outer plate 2 and the inner plate 1. By arranging the branch partition ribs 8 in a staggered arrangement in each concrete cavity 6, a tortuous channel can be formed in the cavity, which facilitates concrete pouring and avoids the formation of large bubbles inside.

[0026] The concrete protective door involved in the utility model is divided into partitions in a cavity formed by inner and outer plates and a ring frame, and is fenced by main dividing ribs. All concrete sub-cavities formed by the fences can also be connected to the pouring port, so that when pouring concrete at the pouring port, all concrete sub-cavities can be filled at the same time, achieving a rapid filling effect, so that the prepared concrete protective door has good impact resistance, is easy to manufacture and process, has complete overall functions, and is highly practical.
