Inverted water-proof roof of building

Abstract: The utility model discloses an inverted waterproof roof of a building, which comprises a structural layer (6), wherein a haydite concrete slope making layer (5), a cement mortar screed making layer (4), a polyethylene polypropylene macromolecule composite waterproof coiled material (3), a multiporous arc polystyrene heat insulation board (2) and a microlith concrete protective layer (1) are arranged on the structural layer (6), and a contiguous gap between adjacent waterproof roofs uses a JS macromolecule composite waterproof coating material for seal and water proofing. The utility model enhances the durability of a waterproof layer, prevents the inner moisture condensation of roof structure and the injure of the waterproof layer, and improves the environment of house microclimate, and moreover, the utility model has the advantages of simple structure, reliable performance and convenient construction.

Construction machinery for pavement

Abstract: PROBLEM TO BE SOLVED: To provide a construction machinery for pavement, capable of comfortably executing expansion/contraction operation and the like of a screed while a signal distribution cable is not exposed to a high temperature and an operator does not have to concern about the signal distribution cableSOLUTION: A construction machinery for pavement provided with a signal distribution cable 21 disposed astride a traveling vehicle body and a screed 15 is equipped with a bending type wiring support device 22 The bending type wiring support device 22 has a pair of connection members 23, 24 of which respective one ends are link-coupled with each other so as to rotatable in a vertically moving direction, the other end of the connection member 24 on one side of the pair of connection members 23, 24 is link-connected to the screed 15 side so as to rotatable in a vertically moving direction, and the other end of the connection member 23 on the other side is link-connected to the traveling vehicle body side while enabling the traveling vehicle body to rotate in lateral width and vertical directions The signal distribution cable 21 is disposed along the pair of connection members 23, 24

Screeding apparatus and method

Abstract: A screed assembly apparatus for loose or plastic materials such as placed and/or poured, uncured concrete previously placed on the ground or another support surface, includes a screed frame, and mounted thereon, a striker for engaging and spreading the materials and a rotatable auger for moving the material longitudinally along the screed frame. The auger provides a pair of intertwined spiral flight coils. The striker is spaced to one side of the auger and in parallel thereto. An auger mounting means and a motive power means are engaged for rotating the auger to remove excess portions of the concrete from the pour.

Device for securing heating pipes and/or reinforcing grids, in particular for floor-heating systems

Abstract: The invention relates to a device for securing floor-heating-system pipes at a distance from an underlying floor and at least one reinforcing grid at a distance from the underlying floor, said reinforcing grid being arranged between the floor-heating-system pipes and the underlying floor. According to a modification, the device according to the invention has an extension piece, as a result of which the heating pipes can be provided at a greater distance from the underlying floor and, if appropriate, a further reinforcing grid can be provided. By arranging the floor-heating-system pipes as near as possible to the surface of the screed to be filled, a very low resistance to heat transmission is achieved.
