Abstract

The utility model relates to a cement concrete hollow block. The utility model is composed of a block body, a central macropore, twelve small holes and a plurality of shallow grooves, wherein, the small holes are uniformly arranged at the circumference with equal intervals; the shallow grooves are provided with four side surfaces. The utility model is shaped by that mould boxes are ejected. Rib-shaped spaces which are uniformly arranged between the macropore and the small holes make the integral structure of the block have balanced stress distribution; under the condition of equal volume weight, the load bearing of the utility model is bigger than the load bearing of other building blocks, and the strength is higher. The utility model which is especially suitable for replacing hollow clay bricks can be used as a building load-bearing wall and buildings with load bearing and without load bearing.

Description

The cement concrete building-block

The utility model relates to a kind of building block, particularly the cement concrete building-block.

General employing of light cement concrete block for the instead of clay brick adds macrovoid to reduce unit weight.Because large-spacing that macrovoid forms and thin-walled have brought difficulty to the brill embedded part operation in built-in fitting operation during the building operations and the later stage decoration, embedded part can't arbitrarily be fixed or be fixing not firm often.Very easily damaged in manufacturing, transportation and work progress in addition.

The purpose of this utility model provides a kind of new cement concrete 13 hole building blocks that substitute at present general structural clay tile and other building-block.

The utility model cement concrete building-block carries out conventional maintenance to finished product after adopting diaphragm capsule to annotate to smash moulding with cement concrete.Structurally the macropore with building block central authorities is the center, equidistantly arranges 12 apertures all around, makes to form uniform rib shape between central macropore and the aperture at interval.Four sides of building block have several shallow slots.The central macropore of building block and all around aperture can be square opening or circular port.

Adopt said structure, the integrated stress of building block is evenly distributed, under the situation that unit weight equates this building block bigger than other building block load-bearing, intensity is higher.The various pre-buried and brill that the arrangement of apertures of this building block is more convenient on the wall body structure buries construction.This building block is particularly suitable for the instead of clay hollow brick as building bearing wall and other need load-bearing and non-bearing structure by laying bricks or stones.

Below in conjunction with description of drawings example structure of the present utility model.

Fig. 1 is a top plan view of the present utility model.

Fig. 2 is an A-A sectional drawing of the present utility model.

Shown in Figure 2 as Fig. 1, foursquare building block body 4 is provided with central macropore 1,12 apertures 2 all around, and the side has several shallow slots 3 all around.Building block body central authorities macropore 1 be a through hole, and 12 apertures 2 be blind hole, blind hole be provided with a little air-vent in case during the building block demoulding generation negative pressure be out of shape.Shallow slot 3 increases rugosity in order to whitewashing for making block surfaces all around.
