Detailed Description
As shown in figures 1 and 2, a seamless connection structure of a prefabricated staircase and a wall body comprises a cement layer 3 arranged between a prefabricated staircase 1 and the wall body 2, the prefabricated staircase 1 adopts the existing common prefabricated staircase, the cement layer 3 is arranged between the prefabricated staircase 1 and the wall body 2, the cement layer 3 is made of expansive cement, gaps are often generated between the prefabricated staircase and the wall body due to the reasons of errors and the like in the installation process of the prefabricated staircase and are difficult to avoid, therefore, the cement layer 3 is arranged in the gaps and is blocked, a plurality of support rods 4 which are horizontally arranged are uniformly arranged in the cement layer 3 along the length direction of the prefabricated staircase 1, two ends of each support rod 4 are respectively fixed with the end surface of the prefabricated staircase 1 and the wall body 2, specifically, two ends of each support rod 4 respectively extend into the end surfaces of the wall body 2 and the prefabricated staircase 1, a sealing bottom plate 5 is arranged at the bottom of the prefabricated staircase 3 along the length direction, the width of sealing bottom plate 5 is unanimous with the width on cement layer 3, sealing bottom plate 5 is last to be equipped with the connecting rod 6 with 4 one-to-one of bracing piece along length direction, the top of connecting rod 6 is connected with the middle part of bracing piece 4, adopt this kind of mode installation sealing bottom plate 5 to ensure that sealing bottom plate 5 has sufficient bearing capacity, prevent to pour into cement in the gap and advance when forming cement layer 3's operation, because of the weight of inflation cement or inflation extrusion make installation sealing bottom plate 5 take place the displacement, and then influence the normal use of this structure.
The top on cement layer 3 is equipped with sealed roof 7, sealed roof 7 is the trapezium structure with the step face looks adaptation of prefabricated staircase 1, the lower surface of sealed roof 7 is equipped with the elastic layer 9 that constitutes by sponge material, the width of sealed roof 7 is unanimous with the width on cement layer 3, sealed roof 7 and sealed bottom plate 5 can constitute a space of pouring into cement, pour into expansion cement in this space and can constitute cement layer 3, prefabricated staircase 1 is close to the terminal surface of wall body 2 and the corresponding department of wall body 2 and prefabricated staircase 1 is equipped with a plurality of inflation holes 8, the effect of setting up inflation holes 8 is, make the expansion cement that constitutes cement layer 3 expand to inflation holes 9 in the in-process that the inflation warp, give its inflation deformation space, prevent its stress oversize, cause the extrusion to make it take place to deformation sealed roof 7 and sealed bottom plate 5.
The utility model discloses a use mode as follows:
firstly, the prefabricated staircase 1 is installed, the installation mode of the prefabricated staircase adopts the installation mode of the existing common prefabricated staircase, the prefabricated staircase 1 and the side wall body 2 close to the prefabricated staircase can normally generate a gap of 1-3cm in the installation process, meanwhile, the support rod 4 is arranged in the gap, the specific arrangement mode is that holes are formed in the end face of the prefabricated staircase 1 and the wall body 2, then one end of the support rod 4 is inserted into the hole of the wall body 2, then the transverse prefabricated staircase 1 is moved to enable the other end of the support rod 4 to enter the hole in the end face of the prefabricated staircase 1, on the next step, the position of the sealing bottom plate 5 is adjusted to enable the sealing bottom plate 5 to be located at the bottom end of the gap, then the sealing top plate 7 is installed, and after the sealing top plate 7 is installed, a gap can be reserved at the top of the sealing top.
Then can pour into expansion cement in gap 3 through the breach at the top of roof 7, thereby form cement layer 3, be equipped with inflation hole 8 because of the terminal surface of prefabricated staircase 1 and the relevant position department of wall body 2, the certain expansion deformation space of expansion cement has been given, thereby the effectual expansion cement that has prevented is because of the pressure of expansion deformation to sealed bottom plate 5 and sealed roof 7, meanwhile elastic layer 9 that the lower surface of sealed roof 7 set up can be deformed by pressure when receiving the pressure of expansion cement, further reduced the pressure to sealed roof 7, the normal use of this structure has been ensured, can accomplish the shutoff to prefabricated staircase gap after waiting that expansion cement solidifies to form cement layer 3.
Compared with a mode of directly pouring cement mortar, the connection structure is firmer and firmer, no crack is generated, and the filled gap is matched with the stair step surface, so that the connection structure is more attractive.
