How to deal with the seams between the hollow core slabs of the new house?

First, the original filling between the gaps of the hollow slab is cleaned up, and then the installed middle seam is re-cut with a special sewing machine to minimize the gap width difference between the plates, and then fill it with marble glue close to the color of the plate. It is required to be close enough to the color of the original panel.

Fill the adjusted marble glue again, because there will be a certain degree of shrinkage after the marble glue is completely solidified, so the marble glue should be slightly higher than the level of the plate, so that it will not be filled many times.

The grinding and polishing sheet and grinding filler are used to make it a horizontal plane with the hollow core plate, which increases the overall feeling, solves the problem of high and low position between the gaps, and prevents the gaps from returning to black again.

With the special cutting grinding disc, the cutting position is carefully polished, so that it becomes a flat whole with the plate.

The hollow plate crystallization powder and crystallizer are used to polish with the crystal surface grinder, and the plate and the crystallization powder are subjected to a physical and chemical comprehensive reaction under the action of high temperature under the heavy pressure of grinding to form a dense and hard crystalline protective layer.

It is not possible to lay a brick wall on a prefabricated hollow core slab, there is no beam bracket underneath, you can consider a lightweight board or infill wall, which is lighter in weight. It can be raised 40 cm, and the drainage pipe goes to the outer wall, pay attention to waterproofingwith a water repellent agent.

First use waterproofing agent mixed with cement mortar to do it at the base of the bathroom, and after it is dry, then use waterproofing agent mixed with cement ash to brush a layer on the surface of the first time. With the coil, first clean the base layer and dry the base layer, then spread the coil on the ground, and heat the coil with a spray gun, which is the gap bonding between the coil and the coil. However, the membrane is relatively fragile, and the surface is easy to be broken by the stones when backfilling, resulting in water leakage.

Non-woven fabric, which is similar to cloth, after brushing the base layer with cement mortar thinly, it can be directly spread on it.

The joints between the hollow slabs, filled with fine stone concrete, are tamped. The wide seam should be reinforced and the template should be hung below. Very fine seams, the stones can't go down, and they are filled with cement mortar.

How to deal with the difference in the plate seam when the hollow core slab is laid? Please give specific steps [[can be dealt with or not dealt with depending on the situation]].

When the slab gap is large, it is necessary to add steel bars to make fine stone concrete [method In fact, at the joint, the concrete should be poured to create a small beam of I-section along the long direction of the hollow slab, and the trabecular also has a role that is to connect the two hollow slabs into a whole Propolis boiled more and then connected into a piece into an overall version of the windy early summer, not only the formwork, you can use the hanging mold process construction This method The construction progress is fast and the follow-up construction is not like cast-in-place concrete to wait for the strength of the concrete Disadvantages The seismic performance is slightly poor].

Is it a prefabricated hollow core slab? When the slab joint difference is large, steel bars should be added to make fine stone concrete.
