Abstract

The invention discloses a novel self-insulating constructional column which is positioned at the joint of a small-sized hollow block wall, and reinforced concrete is cast to be a column through the constructional column. The constructional column is characterized in that two same part-open insulation blocks with multi-row cores are built layer by layer in a staggered way so as to form the column wall; the column core is cast with reinforced concrete to form the constructional column; the part-open insulation block with multi-row cores is internally provided with parallel bar-type through holes; heat insulation materials are filled in the bar-type through holes; and at different wall joints, the constructional columns and the core columns compose straight constructional columns and L-shaped constructional columns respectively. Due to the self-insulating mode, the overall performance of the wall can be ensured; since the cold and hot bridge is cut off by the holes arranged in a staggered way, the cold and hot bridge is blocked and a good thermal insulation effect can be obtained; simultaneously, since the insulation blocks with multi-row cores are built layer by layer in the staggered way to form the column wall, a formwork needs not to be supported separately, so that the formwork and labour power are saved and the construction is convenient. The self-insulating constructional column is convenient for promotion and has great application value.

Description

A kind of novel from the heat-insulation and heat-preservation constructional column

Technical field

The application relates to a kind of novel from the heat-insulation and heat-preservation constructional column

Background technology

At present, the building energy consumption of China has accounted for about 30% of national total energy consumption.And in American-European developed country, building energy consumption can account for higher.And popular External Walls Heating Insulation has external wall outer insulation, the gentle sandwich wall of exterior wall insulating at present.Interior insulation is to add in the inside of external wall structure to do insulation layer.Because insulation layer is made in body of wall inside, has reduced the usable floor area of the commercial house; Next is the secondary decoration that influences the resident, does not hang the weight of decoration painting and so on the indoor wall, and interior wall suspension and mounting article are easy to destroy internal insulation structure; Be phenomenons such as body of wall is mouldy in possibly producing once more.External Thermal Insulation Technology for External still has jejune place, such as constructional difficulties and cost than higher, run into that bad weather comes off easily, seepage, and can not tile fixing with hang defective such as marble, even the danger of initiation fire is arranged.The siphonal lobe wall of tradition sandwich wall can't change maintenance difficult.And because the siphonal lobe wall is a non, under the effect, siphonal lobe wall easy of crack is destroyed outside other planes such as wind or earthquake.The conservation measures of traditional heat-preserving wall just seems and is difficult to satisfy the demands that this just requires a kind of simple and effective novel energy-conserving body of wall.

Constructional column be mainly used in length bigger from heat-insulation and heat-preservation infilled wall and multilayer load-bearing in heat-insulating and heat-preserving wall.Constructional column can guarantee the integrality of wall ability, prevents thermal cracking and settlement crack, and the infilled wall at a lot of positions all will adopt constructional column.Traditional interior insulation can not be blocked cold and hot bridge fully with outer heat preservation technology, remains in many defectives.This solves the problem of the cold and hot bridge of post part with regard to requiring a kind of simple and effective novel structure post.

The application content

The application mainly solves the cold and hot bridge problem of constructional column part.It is big to solve hollow concrete block wall stem stem quantity, constructional difficulties, the unmanageable weakness of concrete quality.Adopt this novel characteristics that have high insulating effect, easy construction saving template from the heat-insulation and heat-preservation constructional column.The application's purpose realizes through following technical scheme.

A kind of novel from the heat-insulation and heat-preservation constructional column, form post jamb by successively staggered the assembling of multi-form many rounds insulation blocks, build steel concrete again and form.Many rounds insulation blocks width adds that the mortar gray seam thickness equals wall thickness.In that row's strip through-hole of many rounds insulation blocks outside, insert the heat-insulation and heat-preservation material before building by laying bricks or stones; Then by the successively staggered formation post jamb that assembles of constructional column dimensional requirement; Build by laying bricks or stones after the completion and in the macropore that forms post jamb, insert reinforcing bar again, concreting and forming from the heat-insulation and heat-preservation constructional column.

Adopt this mode from heat-insulation and heat-preservation, can guarantee integrality of wall can, prevent thermal cracking and settlement crack; And, blocked cold and hot bridge because cold and hot bridge is cut off by staggered hole, can play good heat insulating effect; Simultaneously because the successively staggered formation post jamb that assembles of many rounds insulation blocks; So just do not need again formwork separately, saved template and manpower, easy construction.Make this be convenient to promote the use of from the heat-insulation and heat-preservation constructional column.Has very big using value.

The specific embodiment

Below will combine accompanying drawing that the application is described further:

Embodiment 1:

A kind of novel from the heat-insulation and heat-preservation constructional column, as shown in Figure 1, for assembling many rounds insulation blocks 1 of constructional column post jamb; When construction, in strip through-hole, insert the heat-insulation and heat-preservation material through assembling combination, form the constructional column post jamb, the cold and hot bridge of blocking-up post part; Can form gingival cyst of mucous gland in the newborn easily and rub with the hands, as shown in Figure 3, in macropore, insert reinforcing bar again after building completion by laying bricks or stones; Concreting forms constructional column.

Embodiment 2:

A kind of novel from the heat-insulation and heat-preservation constructional column, as shown in Figure 2, for assembling many rounds insulation blocks 2 of constructional column post jamb; When construction, in strip through-hole, insert the heat-insulation and heat-preservation material through assembling combination, form the constructional column post jamb, the cold and hot bridge of blocking-up post part; As shown in Figure 4; In macropore, insert reinforcing bar again after building completion by laying bricks or stones, concreting forms constructional column.
