Abstract

The utility model discloses a cast-in-situ non-bearing internal partition free from plastering. The cast-in-situ non-bearing internal partition comprises a partition board and a surface decorative layer arranged on the surface of the partition board, wherein the partition board is provided with a prefabricated cushion layer, a cast-in-situ main body layer and a mortar capping layer from bottom to top in turn. The cast-in-situ non-bearing internal partition free from plastering avoids plastering, reduces the prefabricated procedures in factories, can be reliably connected at nodes, and has low cost. Simultaneously, the cast-in-situ non-bearing internal partition is not easy to crack as adopting a cast-in-situ structure with slight expansion or low retraction, additionally fully considers the technological requirements and technical characteristics of cast-in-situ construction, is convenient to assemble and shape, and is easy to guarantee the indexes of strength, plate flatness and the like. And the effects of the cast-in-situ non-bearing internal partition have been proved through many residence projects in northwest region.

Description

A kind of cast-in-place non-bearing internal partition wall of exempting to plaster

Technical field

The utility model belongs to the body of wall field shaping technique, relates to a kind of house wall, is specifically related to a kind of cast-in-place non-bearing internal partition wall of exempting to plaster.

Background technology

Existing non-bearing internal partition wall, as party wall, the locellus wall of framework house, brick commonly used, building block etc. are built by laying bricks or stones or are made up, and this class internal partition wall is for a long time historical, and is comparatively ripe, is widely used.But need prefabrication, also want two-sided plastering when becoming wall, time-consuming, weight is big, has increased cost.

For this reason, in recent years Application and Development light lath or claim light cellular partition board, as refinforced cement batten, GRC hollow lath, gypsum hollow lath etc., according to China's present " JG/T169-2005 light lath for building partition wall " (promulgation of China Ministry of Construction), " 03J113 light lath internal partition wall " industry standards such as (China Building Standard Designing Inst.'s publication) and installation atlas, the typical construction of light lath wall or one-tenth wall mode are: according to the body of wall height, corresponding light lath is transported to the scene by prefabrication.During installation, emboss pit, the Ban Ding of light lath is coated with full adhesive, by the mutual socket of emboss pit, compacted holding out against, the plate seam is 0-8mm, and is the smaller the better.Light lath marginal belt seam groove amplexiforms the seam band in the seam groove, completely scrape adhesive, the seam crossing at two plate tops, and card is put U type antidetonation card or L shaped steel integrated circuit board, filling pea gravel concreten at the bottom of the plate, after waiting to solidify drying, the coated plate face.This class walling need not to plaster, and is in light weight, can overcome the part shortcoming of above-mentioned allowable ratio of height to sectional thickness of masonry wall or column preferably, but still existence will be prefabricated in the factory in advance, seam is easy to crack, inconvenient, the more high weak point of cost of the big transportation of length.In addition, U type antidetonation card or L shaped steel integrated circuit board are installed, are operated loaded down with trivial details, poor reliability.Also have, light lath is subjected to restrictions such as monolithic weight, transportation installation, and width only is 600mm usually, and when longer internal partition wall was installed, required number was many, and installation workload is big.

Summary of the invention

The purpose of this utility model provides a kind of cast-in-place non-bearing internal partition wall of exempting to plaster, and this internal partition wall is reliably convenient, not easy to crack, cost is low.

The technical scheme that the utility model adopted is, a kind of cast-in-place non-bearing internal partition wall of exempting to plaster comprises partition board and is arranged on the surface decoration layer of partition board external surface, and partition board is bottom-up to be disposed with prefabricated bed course, cast-in-place body layer and the clay layer that binds.

Characteristics of the present utility model also are,

Between the adjacent partition board side, partition board side and adjacent pillar or the gap width between the wall be not less than 30mm, is filled with the caulk compound stick in the gap, partition board and caulk compound stick constitute wall base body;

Also be provided with top antidetonation reinforcement in partition board wherein or the wall base body, one end of top antidetonation reinforcement is fixed in back timber or the floor, remainder is cemented in cast-in-place body layer and clay and binds in the layer, perhaps is cemented in clay and binds in the layer, perhaps is cemented in the caulk compound stick;

Also be provided with top antidetonation reinforcement and bottom antidetonation reinforcement in partition board wherein or the wall base body, one end of top antidetonation reinforcement is fixed in back timber or the floor, remainder is cemented in cast-in-place body layer and clay and binds in the layer, perhaps being cemented in clay binds in the layer, perhaps be cemented in the caulk compound stick, one end of bottom antidetonation reinforcement is fixed in back timber or the floor, the other end is embedded in the prefabricated bed course, and the two ends of steel tie difference drawknot is on the bottom antidetonation reinforcement of top antidetonation reinforcement and correspondence;

When internal partition wall length≤8m, partition board is set to the 1-3 piece;

When the length of internal partition wall was 2-8m, partition board was 2;

Cast-in-place body layer wherein is cast-in-place molded gypsum base concrete slab;

Prefabricated bed course wherein is the cement-base concrete preform strip, and perhaps water-proof gypsum base concrete preform strip perhaps is the concrete block or the machine made brick of building by laying bricks or stones on the ground;

Partition board edge wherein is provided with the seam groove.

The cast-in-place non-bearing internal partition wall that the utility model exempts to plaster need not be plastered, and has reduced the prefabrication link, and node connection is reliable, and cost is low; Simultaneously, adopt microdilatancy or the low cast-in-place structure that shrinks, not easy to crack.In addition, the utility model has also taken into full account the technological requirement and the technical characterstic of cast-in-place construction, is convenient to organize mold forming, and indexs such as intensity, plate surface evenness easily guarantee.Above-mentioned effect is verified in a plurality of residential projects of the Northwest.
