Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The embodiment of the device is as follows:

referring to fig. 1 to 6, there is shown a preferred construction of the basement roof post-cast strip pre-closing device of this embodiment. As shown, the basement roof post-cast strip pre-closing device comprises: the locking mechanism comprises a body 1, a first locking mechanism 2, a second locking mechanism 3 and a buffer mechanism. The body 1 is used for covering the post-cast strip 17, and the body 1 is connected with basement top plates 18 on two sides of the post-cast strip 17. Specifically, the size of the body 1 is larger than the width of the post-cast strip 17, and then the two ends of the body 1 can not only cover the post-cast strip 17, but also be lapped with the top plates 18 of the basement on the two sides of the post-cast strip 17 and connected at the lapping position. During specific implementation, the body 1 is internally provided with a double-layer bidirectional reinforcing mesh, so that the bending and tensile resistance of the body 1 is enhanced.

In specific implementation, the specification of the body 1 is 1.2m 0.12 m. The width direction of the body 1 coincides with the width direction of the post-cast strip 17, i.e., the direction a in fig. 4, and the width of the body 1 is 40cm wider than the width of the post-cast strip 17. The body 1 is internally double-layer and bidirectional with the three-level steel diameter of 16@200, and the steel bars 103 are bound.

The first locking mechanism 2 and the second locking mechanism 3 are respectively arranged on two opposite sides of the body 1. During the concrete implementation, because the size of body 1 can't match with the length of post-cast strip 17, so can set up a plurality of bodies 1 and splice in order to carry out the shutoff to post-cast strip 17. When two adjacent bodies 1 are spliced, the first locking mechanism 2 of one body 1 is locked with the second locking mechanism 3 of the other body 1, so that the two bodies 1 are connected together.

The top (upper part shown in fig. 1) of the body 1 is a part far away from the basement roof 18, and the bottom (lower part shown in fig. 1) of the body 1 is a part contacting with the basement roof 18 on both sides of the post-cast strip 17. Buffer gear sets up in the bottom of body 1 to, buffer gear contacts with the basement roof 18 of post-cast strip 17 both sides, and buffer gear is used for all buffering the basement roof 18 of body 1 and post-cast strip 17 both sides when the basement roof 18 of post-cast strip 17 both sides takes place to subside. Specifically, when the basement roofs 18 on the two sides of the post-cast strip 17 subside, the buffer mechanism has the effect of preventing the deformation of the basement roofs 18 on the two sides of the post-cast strip 17 from affecting the body 1, and simultaneously preventing the deformation of the basement roofs 18 on the two sides of the post-cast strip 17 from being affected by the body 1, that is, the buffer mechanism enables the body 1 not to restrict the deformation of the basement roofs 18 on the two sides of the post-cast strip 17, and meanwhile, the deformation of the basement roofs 18 on the two sides of the post-cast strip 17 does not affect the body 1.
