Disclosed is a device for guiding, conveying, or treating a fiber cable (7), comprising several driven rollers (2, 3, 4.1, 4.2, 4.3, 4.3, 4.4), the fiber cable being guided along the circumference of the rollers so as to partly wrap therearound. The rollers encompass a roller (2) for feeding the fiber cable and a roller (3) for discharging the fiber cable. The remaining rollers (4.1, 4.2, 4.3, 4.4) are disposed relative to the feeding roller and the discharging roller in such a way that the fiber cable can be guided on the rollers at a respective angle of contact of >180 DEG . In order to involve all rollers to the same extent for guiding, conveying, and treating the fiber cable, the feeding roller and the inlet of the fiber cable as well as the discharging roller and the outlet of the fiber cable are arranged relative to each other such that the fiber cable can be guided along the circumference of the feeding roller and the circumference of the discharging roller so as to partly wrap therearound at a respective angle of contact of >180 DEG .

A composite foamed cement slab is composed of a main frame made of steel or concrete, a foamed cement core, a steel truss in the foamed cement core and connected to the main frame, and the surface layer reinforced by anticracking material. Its advantages are high heat-insulation and sound-proofness, high resistance to cracking, impact, water, acid and alkali, high durability and weatherability, light weight and low cost.

The invention belongs to the architecture field, and particularly relates to an architecture structural system assembled by composite architecture boards and a construction method. The system comprises a load bearing partition plate performing functions as the beam and the column of a building and an external wall plate. Transverse frames performing the function of the beam, inner plate structureconnectors and external structure connectors are arranged in a floor plate and a roof plate. The external structure connector comprises a wall bottom connector; an angle connector; a positioning connector; a connector connecting the floor plate, the external wall plate and the partition plate; a connector connecting the roof, the external wall and the gable wall; a ridge connector and so on. The invention is a plate-type total prefabricated housing construction technology, which has the comprehensive service performance of load bearing, shock absorption, hear and sound insulation, high efficiency, energy saving, durability and fire resistance, and conforms to the requirements of the green architecture. The method is capable of rapidly assembling and installing on the field and reducing the total cost of a house, as well as achieving the integration and the industrialization of the housing construction.

The invention relates to a fabricated construction method with construction energy-saving reformation, comprising: firstly, a steel structure connecting plate is additionally positioned on the top part of the original construction structure; a connected layer steel structure fixed to the steel structure connecting plate is positioned in order to connect with the original construction structure; anenergy-saving compound outer wallboard with foaming cement material, a partition panel, a folding floor slab, an energy-saving compound roof panel with foaming cement material are positioned, which are connected with the connected layer steel structure directly or by a plate material connector; a heat insulation and sealing material is filled in the gaps in and out of the board slots or between the board and the original construction structure, namely, the reformation of the energy-saving property of the original construction and the story-adding of the old building has been completed; secondly, a connecting plate of the wallboard and a strut member of the outer wallboard are additionally positioned outside the original construction structure; an energy-saving compound outer wallboard with foaming cement material is positioned outside the outer wall of the original construction, which is fixedly connected with the connector of the wallboard by the strut member of the wallboard; the heat insulation and sealing material is filled in the slots of the outer wallboard, namely, the reformation of energy-saving quality of the outer wall of the original construction has been completed.

Provided is a vehicle seat by which an impact of rear end collision is reduced and of which peripheral structure of a side frame is simplified. A vehicle seat includes: a seat back frame which includes side portions positioned at the sides thereof, a pressure receiving member which is jointed to the seat back frame through joint members and supports an occupant, and an impact reduction member which is disposed on at least one of the side portions to engage with the joint member and to move by a predetermined amount of impact load applied to the pressure receiving member so that the pressure receiving member is caused to move rearward; in which the side portion includes a convex portion protruding in the movement range of the impact reduction member, and the impact reduction member abuts against the convex portion so that the movement of the impact reduction member is prevented.
