Abstract

The hollow concrete tenon block of the utility model is an innovation of the house wall grain configuration and an entire block formed by the mutually connection of two zygomorphic concrete panels and three (or two) cross ribs with round holes in middle. The upper portion, the lower portion, the right portion and the left portion of the utility model are respectively equipped with cogged joints; the wall building can be conducted without mortar adhesion or with a little mortar adhesion. The inner portion of the wall is vertically and transversely formed a plurality of pore passages to provide convenience for pipeline laying. The utility model owns the advantages of light bulk specific gravity, high intensity, fast laying, low cost and even the common bricklayers can conduct laying operation, etc. The utility model can be provided to the adoption of the filler wall, the indoor baffle wall and the main wall of the frame construction.

Description

Hollow concrete tenon-connecting block

The utility model design relates to a kind of hollow concrete joggle building block (hereinafter to be referred as the concrete building block), belongs to building engineering material field.

At present, the habitual loam brick of house wall is built by laying bricks or stones both at home and abroad.Need fetch earth base and build stove high temperature and burn till of this brick exists to take the farmland and plough soil erosion; The complex manufacturing technology cycle is long, consumes energy cost height; This brick intensity difference consumes and builds by laying bricks or stones and motar, and deadweight increases the beam column load; Labor strength is big, and speed of application waits defective slowly.

In recent years, nation-building portion proposes and will " quicken the innovation of materials for wall ", widelys popularize the building block of hollow concrete joggle.Chinese patent CN2062356U has announced a kind of new construction material by retrieval---and " omnipotent building block ", can find to exist following defective again:

H type structure is adopted in 1 this building block, and horizontal cross rib only plays the effect that connects left and right sides concrete panel merely in the middle of it, can't bring into play the mechanical property of building materials load-bearing;

2 end tenons and end slot concrete section are too thin, and it is broken to rupture easily;

3 molding complexity, cost increases; The form removal difficulty, the disadvantages outweigh the advantages for the low grade of turnover rate.

The purpose of the utility model design is that a kind of house wall building block that can give full play to the building materials load performance will be provided.Reach and alleviate building deadweight, use no or little adhesive mortar, construction is easily fast, and is with low cost.And requirement is decorated in the modernization that adapts to the pipeline concealed installation.

The task of the utility model design is to be adhesive with #400 cement, particle diameter for the 5-10 millimeter and in thick river sand make aggregate, flyash and water reducing agent are made additive (can save cement about 20%), stir into all kinds of label concretes by design mixture proportion.Pour into then in the model of making in advance, mechanical pudding moulding again through natural curing, is accurately measured initial set and is reached form removal intensity, quickens the mould turnover, increases production prefabricated concrete building block, makes every effort to reduce construction costs.

Design content of the present utility model and main points: the prefabricated concrete building block of a kind of building construction body of wall by two bilateral symmetry panels 1. with the vertical cross rib in middle three (or two) band hole, garden (preceding cross rib 2., middle cross rib 3., the back cross rib 4.) connect mutually and form.Its basic building block is a day font, and supporting building block is hollow, keeps supplying the supporting use of hypodermis first and last, realizes that the structure fissure of displacement is vertical, strengthens the body of wall earthquake resistant structure; Form two (one of supporting building block) low dip band fan garden inner corner trim 5. hollow from top to bottom in the middle of each basic building block, easy in order to the dismounting core; In cross rib 3. be the T type, plane of structure is wide to be a bit larger tham two times of perpendicular ribs thick (before to be that plane of structure is wide be a bit larger tham cross rib 2. thickness add 4. thickness sum of back cross rib), when building exterior wall by laying bricks or stones, placing mortar has enough areas; Before, during and after cross rib respectively hold tenon 6. end slot 7. be isosceles trapezoid, its obtuse angle reaches 135 °, and is concavo-convex greater than 5 millimeters, in order to increasing the member section, guarantees that each end tenon, end slot are not subjected to constructing operation and transportation collision institute damaged, reaches that to pave the splicing location quick; The hole, garden of every cross rib 8. be outer garden week greater than interior garden week, outer edge surface is low dip, in order to the external mold of rib before and after the dismounting; The garden heart setting 8. of hole, garden is positioned under the cross rib center of gravity side, can guarantee the hole, garden 8. the upper edge cross rib enough sections are arranged, help the carrying construction and do not rupture.

The enforcement of the utility model design must be determined the length of basic building block * highly * width (being the wall thickness degree) according to GB common brick specification, existing construction module commonly used and beam, post design section, and the length of supporting building block should equal (or being slightly less than) half of building block substantially; Height should be consistent with basic building block with width.Concrete enforcement should be considered analogue formation is inverted in the concrete building block, could simplify and make and dismounting, improves the mould turnover rate.

The advantage of the utility model concrete building block is:

The whole members of 1 concrete building block are vertical the setting, can give full play to the performance of building materials load-bearing pressure;

In 2 bodies of wall anyhow line all have the even cloth in duct to communicate, can supply pipelining, interior decoration grace;

3 masonry technologies are grasped easily, and common apprentice can both construct, and is easy and simple to handle, favourable raising work efficiency;

4 building block models are few, from heavy and light.Indoor wall can be built by laying bricks or stones without mortar, favourable reduction engineering cost; The few hurt of house wall reconstruction dismounting building block, the reusability height;

5 energy conservation do not need high temperature sintering.Can gather materials on the spot, utilize stone field barren rock bits or fly ash in electric power plant slag, help the environmental protection of low pollution;

6 the utility model concrete building blocks are a kind of new structure form design in original building material product, rather than novel new varieties building materials, can save considerable testing expenses.

The utility model design the description of the drawings:

The basic concrete building block of Fig. 1 phantom drawing;

The supporting concrete building block of Fig. 2 phantom drawing;

Content among the figure: 1. concrete building block side panel; 2. preceding cross rib; 3. middle cross rib; 4. cross rib after; 5. the concrete building block is hollow; 6. hold tenon; 7. end slot; 8. the pre-Lingering Garden of cross rib hole.

Claims

1, a kind of hollow concrete joggle building block (hereinafter to be referred as the concrete building block) by two symmetrical concrete panels 1. with the vertical cross ribs in middle three (or two) band hole, garden (preceding cross rib 2., middle cross rib 3., the back cross rib 4.) connect mutually and form prefabricated concrete building block.It is characterized in that being the day or the shape of the mouth as one speaks, the supporting use of last hypodermis first and last; Middle form two (or one) low dip band fan garden inner corner trim 5. hollow from top to bottom; Pave and respectively hold 6. end slot frictional force restriction 7. of tenon after forward up and down, reach mutual buckle and build the jail.
