Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the following describes the contents of the present invention in further detail with reference to the accompanying drawings and detailed description. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.

The embodiment provides a post-cast strip cover plate structure, as shown in fig. 1 and 2, including reserving post-cast strip 2 between two cast-in-place strips 1, two insides of post-cast strip 2 are provided with wall body 3 along the length direction mirror image, the height of wall body 3 is greater than cast-in-place strip 1, steel plate 4 is installed at the top of wall body 3, steel plate 4 includes roof 401, and follows the curb plate 402 that roof 401 both sides set up, roof 401 and curb plate 402 transition lock are at the up end of two sets of wall bodies 3.

It should be noted that, after the steel plate 4 is fastened, a small amount of concrete may be used to seal the joint between the steel plate 4 and the wall 3, and other waterproof materials may also be used to seal the joint, which is not limited herein. In addition, the steel plate 4 can adopt an impact device to shatter the concrete at the joint before being dismantled, and then the steel plate 4 is lifted up, so that the recycling of the steel plate 4 is not influenced.

In this embodiment, through two inboard wall bodies 3 that highly are greater than cast-in-place area 1 of setting up of post-cast strip 2 to in the up end lock joint steel sheet 4 of wall body 3, the rainwater can't invade from the junction of wall body 3 and steel sheet 4, and waterproof sealing is effectual, and later stage steel sheet 4 can recycle. Meanwhile, the rigidity, strength and durability of the adopted steel plate 4 are higher than those of other materials such as a traditional wood formwork, the steel plate is not easy to damage and move randomly, and the steel plate can bear the traffic of a common small trolley and the like without damage and movement. The good waterproof effect can realize that basement fitment, installation specialty insert the construction in advance.

For the further waterproof effect who improves, optional, cast-in-place area 1's up end is towards the direction slope setting of keeping away from wall body 3, forms and looks for the slope layer, and the rainwater is difficult to be in piling up the steel sheet 4 and cast-in-place area 1's junction along looking for the low-lying region of slope layer flow direction cast-in-place area 1, avoids corroding steel sheet 4 for a long time.

Aiming at the leakage problem at the two sides of the post-cast strip 2, in some optional schemes, a cement waterproof layer 5 is further arranged between the wall body 3 and the cast-in-place strip 1, the cement waterproof layer 5 covers the upper end surface of the wall body 3, the total height of the cement waterproof layer 5 and the wall body 3 is larger than that of the cast-in-place strip 1, the height of the wall body 3 does not need to be larger than that of the cast-in-place strip 1, and the steel plates 4 are in transition buckling connection with the upper end surfaces of the two groups of cement waterproof layers 5. The concrete that cement waterproof layer 5 provided can prevent from the rainwater entering post-cast strip 2 from waterproof.

Optionally, the cement waterproof layer 5 intrudes into the bottom of the cast-in-place strip 1 to form an arc portion 501. The arc portion 501 is arranged in a later stage, a waterproof layer is additionally arranged, the waterproof layer can be uniformly and continuously coated, and the waterproof weak point caused by inconsistent thickness is avoided.

In some optional schemes, a waterproof coiled material 6 is further laid between the cement waterproof layer 5 and the cast-in-place belt 1, the waterproof coiled material 6 covers the upper end face of the cement waterproof layer 5, the total height of the waterproof coiled material 6, the cement waterproof layer 5 and the wall body 3 is larger than that of the cast-in-place belt 1, the height of the wall body 3 does not need to be larger than that of the cast-in-place belt 1, and the steel plate 4 is in transition buckling connection with the upper end faces of the two groups of waterproof coiled materials 6. The waterproof coiled material 6 can be a thick asphalt polyurethane tire waterproof coiled material, so that the two sides of the post-cast strip are ensured not to leak.

In some optional schemes, a cement protective layer 7 is further laid between the waterproof roll 6 and the cast-in-place belt 1, the cement protective layer 7 covers the upper end face of the waterproof roll 6, the total height of the cement protective layer 7, the waterproof roll 6, the cement waterproof layer 5 and the wall body 3 is larger than that of the cast-in-place belt 1, the height of the wall body 3 does not need to be larger than that of the cast-in-place belt 1, and the steel plates 4 are in transition buckling connection with the upper end faces of the two groups of cement protective layers 7. The cement protective layer 7 is used as a protective layer for the waterproof roll material 6 and the cement waterproof layer 5, and can effectively prevent the waterproof roll material 6 and the cement waterproof layer 5 from being damaged by external force.

In some optional schemes, the steel plate 4 is coated with anti-rust layers on two sides before installation, so that the service life of the steel plate is prolonged. Furthermore, the surface of the rust-proof layer on the upper end surface part of the steel plate 4 is coated with a warning mark for warning engineering personnel that the post-cast strip is not necessarily close.
