Abstract
The utility model discloses an arc-shaped concrete hollow module-card building block, which comprises an arc-shaped outer wall, cross ribs, convex ribs and a haunch, wherein the arc-shaped outer wall and the cross ribs form a major building space; the arc-shaped outer wall and the convex ribs are used for the bond of the building blocks in the upper row and the lower row; and the arc-shaped outer wall, the cross ribs, the convex ribs and the haunch are used for transferring vertical force. Due to the haunch, the force transfer path is more explicit; and due to the cross ribs, the structure has larger resistance to outside transverse loads. Vertical holes are used for arranging vertical reinforcing steel bars and pouring concrete; trapezoidal holes at the lower parts of the cross ribs are used for arranging transverse reinforcing steel bars; and the concrete and the reinforcing steel bars form a net structure with excellent stress performance. After the building blocks are laid, the wall of a well has good waterproof impervious performance due to the height difference between the arc-shaped outer wall and the convex ribs between an upper building block and a lower building block.
Description
Technical field
The utility model relates to borehole wall field, is specially the building block of a kind of arc concrete hollow mould card.
Background technology
Concrete block is used widely in manhole and the construction of other underground installation boreholes wall; But concrete hollow block commonly used at present often exists from great, shortcomings such as power transmission is indeterminate, the many long construction periods of operation, construction inconvenience, water impermeability difference; Not only wasted more material; Wasted ample resources, improved cost, and caused certain hidden danger for the safety of structure and the normal use of building.
Summary of the invention
The purpose of the utility model is to provide a kind of conduct oneself with dignity less, easy construction, minimizing formwork, mechanical characteristic is good and have the arc concrete hollow mould card building block of better waterproof impervious characteristic.
The utility model comprises two arc outer walls, two cross ribs, two fins, two haunches; It is characterized in that a last placement surface that is applicable to alignment is respectively arranged at its described two arc outer wall tops; Article two, a following placement surface that is applicable to alignment is respectively arranged at the arc outer wall bottom; Last placement surface extends to form the haunch that improves stress performance to building block inside; Haunch extends upward the fin that is formed for agreeing with; The arc outer wall on both sides, fin and haunch are connected through two cross ribs perpendicular to arc outer wall; The top of cross rib have one be applicable to the alignment and in the concordant placement surface of fin, the cross rib bottom is higher than the following placement surface of arc outer wall, in the cross rib lower central a trapezoidal hole that is used to arrange transverse reinforcement and core grouted concrete bottom horizontal flow sheet is arranged; The arc outer wall on both sides, fin, haunch and two cross ribs are formed for arranging the vertical hole of vertical reinforcement and core grouted concrete, and each edge of arc outer wall respectively has a leg-of-mutton chamfering that forms vertical mortar seam.The utility model be a kind of arc to the quantic building block, when building by laying bricks or stones not only arc outer wall align, and cross rib also aligns, and encloses a circular borehole wall, not only guaranteed the continuity of vertical Path of Force Transfer, also reduced the operation of formwork in the work progress.Arc outer wall, cross rib, fin and haunch are used to transmit vertical force, because the existence of haunch makes Path of Force Transfer clearer and more definite, the transmission of power is more even, and cross rib makes structure for outside transverse load bigger resistivity arranged.Vertical hole can be arranged vertical reinforcement, and trapezoidal hole can be arranged transverse reinforcement, and trapezoidal hole has certain area, guarantee core grouted concrete after, the borehole wall is inner to form a kind of netted structure, has superior overall performance.Simultaneously, the arc interlocking concrete block makes building well wall more simple and convenient, has accelerated speed of application.
The height of the utility model fin is greater than the height of cross rib bottom placement surface under the arc outer wall, and this difference in height makes the borehole wall have good waterproof impervious characteristic.
The borehole wall that the utility model forms is reserved with vertical groove and the transverse concave groove that is used to fill mortar, and vertical groove and transverse concave groove all are positioned at the building block outward flange, can direct injection or smear mortar.

Fig. 1 is the axonometric drawing of main piece;
Fig. 2 is the top view of main piece;
The axonometric drawing that Fig. 3 builds for the building block group.
Description of reference numerals is following:
1-arc outer wall 2-haunch 3-fin 4-goes up the trapezoidal hole of placement surface 5-
Placement surface 9-chamfering under the vertical hole 7-of the 6-cross rib 8-
The vertical groove 11-of 10-transverse concave groove.
The specific embodiment
Below will combine accompanying drawing that the utility model is described further:
Fig. 3 has provided the group of arc concrete hollow mould card building block and has built sketch map.As shown in the figure, the construction of its masonry way and common reinforcing bars building block body of wall is similar, and the limit is placed the building block limit and arranged reinforcing bar, concrete perfusion then.
