Spacer for reducing concrete usage of construction slab

Abstract

The invention provides a cushion block which can reduce the transfer of noise and vibration between upper and lower floors via a floor slab, at the same time, reduce thickness of the floor slab and using quantity of concrete. Therefore, the invention relates to a hollow plastic cushion block which is filled in the floor slab to reduce the using quantity of concrete. The structure of the cushion block has the characteristics that: shape of horizontal section is round; transverse diameter of vertical section is longer, vertical (perpendicular direction) diameter is shorter, presenting the transverse convex shape; block body is ellipse with flat urn shape at top and bottom.

Description

Technical field [0001] The invention relates to a cushion block used in a floor slab, which can be used to reduce the amount of concrete used in the floor slab. Background technique [0002] Concrete is used for floor construction between floors and floors of high-rise buildings. Because concrete has a very high compressive strength, but its tensile strength and flexural strength are low, the strength of a floor slab made of concrete only must be small, so The truss structure (5) made by weaving steel bars (8) is usually filled inside the floor slab as shown in Fig. 9. Here, when the floor slab is produced by casting concrete, it is necessary to fill the truss structure (5) inside it to increase the flexural and tensile strength of the floor slab and control the generation of concrete cracks. [0003] However, the floor slab erected between the building floor and the floor is the common part of the upper and lower floors. While forming the upper floor, it also forms the ceiling o...

Problems solved by technology

[0006] However, the above-mentioned conventional pads (32) are simple to manufacture, easy to install, and have the simplest appearance design, so people are used to making the pads spherical for use, but in order to reduce the amount of concrete used, the space inside the ball must be increased. The diameter of the ball must be increased for this reason, and now the thickness (t) of the slab (33) also increases correspondingly along with the increase of the pad (32) diameter, so the overall height of the building will also increase, and the negative effect produced thereby is slightly Accidents can offset the effect of reducing the amount of concrete used

[0007] Another problem is that if the thickness of the concrete covering the upper and lower parts of the spacer (32) is reduced in order to reduce the thickness (t) of the floor slab and the amount of concrete used, it will be accompanied by the negative effect that noise and vibration are easily transmitted to the lower floor.
