Description

H type concrete block

Technical field

The utility model relates to a kind of construction material, particularly relates to a kind of concrete block of masonry panel.

Background technology

Concrete block is a kind of novel wall material, has lightweight, joint soil, characteristics of energy saving, meets the wall reform policy.And, having the characteristic of reinforced concrete structures such as intensity height, ductility be good again by the reinforced masonry structure of its construction, it is to melt masonry and concrete performance in a kind of materials for wall of one, at present by the many national extensive uses of America and Europe.Reinforcing bars building block masonry retaining wall is used in a large number in the U.S., safety, economic, attractive in appearance, and each side is with the obvious advantage.

At present domestic most widely used be the small-sized ordinary concrete building block.But it does not allow to adopt straight joint to build by laying bricks or stones when masonry panel, because, when straight joint formula masonry panel is taked in the small-sized ordinary concrete building block, in body of wall, can form straight joint, stability and bearing capacity all can descend greatly.Though adopt correct fissure of displacement building construction method can avoid this problem, it can only adopt joint bar technology when building the concrete reinforcement body of wall by laying bricks or stones, be difficult for accurately for the vertical reinforcement location in the body of wall, construction quality is difficult to guarantee.

Existing N formula multifunctional building block also can accurately be located to reinforcing bar, but can only place reinforcing bar every the hole, can not satisfy the requirement that reinforcing bar is placed in the every hole of a lot of structural requirements.

For example, when body of wall mainly bears from out-of-plane load (as outer wall of basement and reinforcing bars building block masonry retaining wall), if reinforcing bar position can not get guaranteeing in the reinforced masonry wall, the bearing capacity of body of wall is difficult to realize the set goal, and the security performance of building can not get ensureing.What the construction of present reinforcing bars building block build shearing force wall structure and reinforcing bars building block masonry retaining wall structure was all taked is to build the technology of inserting vertical reinforcement about the 3m height again, is difficult to the correctness of the position of assurance vertical reinforcement in the practice of construction.And the correctness of the position of vertical reinforcement has material impact to the stressed particularly body of wall of structure stressed.And N formula multifunctional building block be owing to can only place reinforcing bar every the hole, and in the primary structure member, the diameter of reinforcing bar will be excessive the plane outside, makes that concrete is difficult to vibrate, and is difficult for the safety of assurance structure.

The utility model content

The technical problems to be solved in the utility model just is: at not determining reinforcement location or can not be with the seam shortcoming that reinforcing bar is placed in every hole when building by laying bricks or stones in the above-mentioned reinforcing bars building block body of wall under mainly bearing plane external load situation effectively, provide a kind of concrete block and end thereof with low cost, easy construction to join piece, this building block can be carried out the same seam of hole, rib, wall alignment and build by laying bricks or stones when building the arrangement of reinforcement body of wall by laying bricks or stones, in work progress, can accurately easily must determine the position of reinforcing bar in body of wall, and can reinforcing bar be set every hole easily; Whole wall construction technology difficulty is little, and construction quality is easy to ensure.

For reaching above-mentioned target, the solution that the utility model proposes is: its transverse shape is a H shape, the building block both ends open, and the centre is provided with cross rib.As required, on the cross rib level trough can be set.

The brick-building art of the utility model H type blockwork is characterised in that: elder generation is the position of reinforcing bars building block masonry vertical reinforcement fixedly, uses H type concrete block masonry again.Because be to adopt H type concrete block masonry, building block need not to penetrate from the reinforcing bar top, can satisfy the requirement that makes effective location of reinforcing bar and easy construction two aspects simultaneously, and can place vertical reinforcement in every hole.Every block one to three skin is placed horizontal reinforcement, with the vertical reinforcement colligation together, horizontal reinforcement and vertical reinforcement can well be located, and have avoided the bad location of joint bar technology reinforcing bar, stress performance can affected problem.Per three to four micromicros are to water concrete one time, and concrete adopts ordinary concrete to get final product.It is simple and convenient to construct.

Compare with the small-sized ordinary concrete building block, advantage of the present utility model is: (1) is though body of wall is to build by laying bricks or stones with seam, but behind grout, because the grout concrete is with it gang in the relative body of wall of adjacent H type building block both ends open, body of wall straight joint can not occur, the stability of body of wall and bearing capacity do not descend, on the contrary owing to building block in body of wall has realized that rib alignment in hole improves the resistance to compression bearing capacity from top to bottom; (2) under the situation of grout, stem stem kernel of section from top to bottom remains on the same axis, and the shearing resistance effective depth of section of stem stem reality does not reduce, thereby the shear strength of grout block masonry improves again; Can fix reinforcing bar earlier when (3) constructing, fixing earlier reinforcing bar can not exert an influence to building by laying bricks or stones of blockwork; Building block can be walked around reinforcing bar and builds by laying bricks or stones when building by laying bricks or stones, is particularly suitable for building by laying bricks or stones of reinforcing bars building block masonry retaining wall; In to the masonry wall grout, can select ordinary concrete as required, irritate once, also can select large fluidity grout concrete every about 3m, to irritate once every 600mm～800mm; (4) the utility model is improved the building block geometric format, and has changed the construction technology of traditional building block, and it is simple and convenient to construct; (5) but mechanization production, constant product quality.

Compare with N formula functional normal concrete block, advantage of the present utility model is: the building block of (1) H type is when building the reinforcing bars building block body of wall by laying bricks or stones, can take the every hole of pre-aligned reinforcement rebar craft be provided with vertical spacer bars with the seam build by laying bricks or stones, and N formula functional normal concrete block can only take every the hole be provided with vertical spacer bars with the seam build by laying bricks or stones; (2) for stressed bigger body of wall outside the plane, the building block of H type can be provided with spacer bars in every hole, and like this, bar diameter is moderate, is easy to concrete perfusion; And N formula functional normal concrete block can only be taked every the hole vertical spacer bars to be set, and will cause bar diameter thick excessively, and quantity is too much, is difficult for meeting design requirement and the construction quality requirement.
