Example 1:
as shown in fig. 1-5:
a positioning method for embedded sleeves of a multi-layer building bottom plate comprises the following steps:
step 1, selecting a reserved hole on a foundation slab 1 (a slab of a first floor) as a first reference hole (not labeled in the figure), and determining the coordinate positions of the axes of other reserved holes on the foundation slab through a bottom layer positioning mechanism in a multi-layer building slab embedded sleeve positioning device by taking the axis position of the first reference hole as a standard, wherein after the axis coordinate positions are determined, the coordinate positions of embedded sleeves of an upper layer of the foundation slab to be poured can be determined, and the accurate positions of all the embedded sleeves can be easily found only by the fact that the coordinate system of the upper layer of the foundation slab to be poured is the same as the coordinate system of the foundation slab;
step 3, arranging an upper layer positioning mechanism in a multilayer building bottom plate embedded sleeve positioning device above the bottom template 2 and at the round hole of the second reference hole 14, enabling the coordinate systems of the upper layer positioning mechanism and the bottom layer positioning mechanism to be the same through adjustment, referencing the coordinate positions of the axes of all the reserved holes on the foundation bottom plate, determining the positions of all the reserved holes on the bottom plate to be poured through the upper layer positioning mechanism, and arranging an embedded sleeve 15 at the positions;
step 4, arranging an embedded sleeve 15 at the second reference hole 14, and casting the bottom plate to be cast into a shape after the reinforcement cage is built;
and 5, positioning the positions of the embedded sleeves of other floors according to the method described in the step 2-4.
In the prior art, each embedded sleeve needs to be positioned one by one, and each positioning time needs to irradiate temperature measuring test paper through laser and rotate to burn out the position mark of the embedded sleeve, so that obvious defects exist in the mode that: the line width of the annular line of the position mark burnt out by the temperature measurement test paper is difficult to master, the line width is inconsistent due to long burning time or poor laser energy consumption, errors are also caused due to positioning based on the annular line, in addition, along with the rising of floors, the laser line passes through the embedded sleeves of the layers below to sinter and position the temperature measurement test paper on the bottom template of the bottom plate to be poured, and the edge of each embedded sleeve below is inevitably blocked, so that construction is inconvenient. In the invention, the position of the first reference hole can be determined according to the inner diameter of the first reference hole only by determining the axial position of the first reference hole, and the position of the second reference hole can be rapidly determined by determining the axial position of the second reference hole through a longitudinal laser line positioned at the center. Along with the lifting of the floors, the invention can not cause the problem that the longitudinal laser lines are blocked because the longitudinal laser lines at the periphery are separated from the inner walls of the second reference holes at the upper layer, and the operation is simpler.
