Problems solved by technology

Both the hollow-core floor technology and the ribbed floor technology are floor structures. During the long-term engineering practice, it was found that most of the hollow-core floor technologies use embedded mandrels to form cavities in the floor. Further reduce the amount of steel and concrete, but although a certain amount of self-weight has been reduced, there is still a certain amount of cumbersome steel and concrete. Therefore, it is necessary to better improve the mandrel so that it can effectively overcome the above problems. Improve safety performance

Abstract

The invention discloses a composite mandrel for construction, which includes an adsorption vibrator, which is arranged on the upper surface of the eaves, and the eaves and the adsorption vibrator are connected by vertical external molds arranged on both sides of the adsorption vibrator. The vertical outer mold has a triangular structure, which are fixedly connected with the eaves and the adsorption vibrator by superglue. There are corresponding ventilation holes between the vinyl board and the composite lining board. The polystyrene board has a convex edge extending near the bottom outside. The angle between the convex edge and the polystyrene board is between ten and thirty degrees. A corresponding cavity is opened between the inner bottom surface of the vinyl plate and the composite liner, and a fixing piece is installed in the cavity. The composite mandrel for this building is made of lightweight materials, which is very convenient for production and transportation, simple in construction, good in fire resistance, good in pressure resistance and sealing, and can effectively guarantee the quality of construction and installation.

Description

technical field [0001] The invention relates to a composite mandrel, in particular to a composite mandrel for construction. Background technique [0002] The advancement of construction technology promotes the diversification of building structures. Compared with traditional residential houses, buildings such as gymnasiums, large conference halls and underground garages usually have the characteristics of large spans and large bays. The demand for load bearing is due to the thicker floor slab and wider and higher beams, so the overall self-heaviness of the floor slab is large, and the amount of concrete and steel bars is relatively large. Both the hollow-core floor technology and the ribbed floor technology are floor structures. During the long-term engineering practice, it was found that most of the hollow-core floor technologies use embedded mandrels to form cavities in the floor. Further reduce the amount of steel and concrete, but although a certain amount of self-weigh...
