Through the cooperative arrangement of the first supporting piece, the second supporting piece and the supporting plate, when the first supporting piece and the second supporting piece need to be taken down, only the connecting rod and the movable rod need to be held, and the movable rod moves to drive the limiting block to move through the adjusting rod to be separated from the limiting tooth groove in the surface of the supporting rod; therefore, the first supporting piece and the second supporting piece can be easily taken down from the supporting plate, the disassembling difficulty of the first supporting piece and the second supporting piece is reduced, and then the demolding efficiency is improved.

Description

[0002] Concrete floor drainage ditches are often used for concrete floors, indoor concrete floors with water, and outdoor concrete floors. However, with the development of industrial construction, various disciplines have been integrated and interpenetrated, and concrete drainage has been applied in industrial construction projects. Concrete drainage is difficult to construct due to the small cross-sectional dimensions of the components and the limited working space.

[0003] The Chinese patent with announcement number CN210887509U discloses a concrete cast-in-place floor drainage ditch mold, which is characterized in that it includes a support member A and a partition, and the partition is provided with two groups, and the partition is in the shape of an "and", that is, it includes two vertical bodies and a horizontal body, the vertical bodies are respectively arranged on both sides of the horizontal body, the vertical body is perpendicular to the horizontal body, and the vertical body and the horizontal body are both strip-shaped plate bodies, one vertical body is arranged above the horizontal body, and the other vertical body is arranged below the horizontal body, the support member A spans between the partitions, the support member A is a strip body with an "L"-shaped cross-section, the support member A includes a plate body A and a plate body B, one side edge of the plate body A and the plate body B is connected in a "V" shape, and the other side is a free edge, the free edge end is provided with a slot, the slot is strip-shaped and perpendicular to the free edge, and the upper vertical body can be embedded in the slot.

[0004] However, the above technical solution has the following shortcomings: after the pouring is completed and the concrete is solidified, the support parts need to be removed before the partition can be removed. Since the support parts are between the two partitions, after the concrete is poured, the support parts are subjected to the inward extrusion force exerted by the partitions, which makes it difficult to remove the support parts from the partitions, affecting the demolding efficiency.
