Disclosed are a deck plate for a floor slab, a slab module integrated with an ondol pipe, and a floor system integrated with an ondol pipe. The deck plate for a floor slab according to the present invention forms the floor slab of a building and includes a pipe installation groove configured to have an ondol pipe placed therein and iron reinforcing rods installed within the deck plate. The deck plate is made of concrete. In accordance with the present invention, since the deck plate that is previously fabricated using processes, such as concrete forming and curing, in an additional manufacturing plant is used to form the floor slab of a building, the construction time and the cost of construction can be substantially reduced because the concrete forming and curing processes need to be performed in a building construction site. Furthermore, since an ondol pipe has only to be disposed in a pipe installation groove already formed in the deck plate for the purpose of a heating construction in a construction site, the construction time and the cost of construction can be reduced because additional heating panel construction is omitted in a construction site.

The present invention relates to a manufacturing method for acoustic foam. More specifically, the manufacturing method for acoustic foam including resin foam containing an open cell and a closed cell includes physically blowing up the closed cell by applying impact to one or both sides of the acoustic foam in a contact or non-contact manner. The method improves shock-absorption, mechanical strength, workability, heat insulation, and noise blocking/dispersion of the acoustic foam.

The present invention relates to a floor impact noise isolator for construction and a method for constructing a floor using the same. The present invention provides a floor impact noise isolator for construction, including a noise isolating body; and a reinforcing member formed with an inflow hole which is filled with mortar. In addition, the present invention provides a method for constructing a floor of a building, comprising the steps of installing the floor impact noise isolator according to the present invention; and introducing mortar into the inflow hole formed in the reinforcing member of the noise isolator. According to the present invention, the noise isolating body is supported by the reinforcing member and the inflow hole formed in the reinforcing member is filled with mortar to thereby have excellent strength and prevent a crack from occurring in the mortar layer. Further, a local load distribution is transformed into a surface load distribution, thereby improving a noise isolation property.
