Description

Local reinforcing apparatus of outer heat preservation wall

Technical Field

The utility model relates to a local reinforcing device for an external thermal insulation wall surface, and belongs to the technical field of external wall thermal insulation of constructional engineering.

Background

The traditional external wall insulation is a 'rear anchoring and pasting method', namely: firstly, an outer wall structure is made, then the heat-insulating layer is directly fixed by rivets, and then plastering covering is carried out outside the heat-insulating layer, which is commonly called thin plastering.

The service life of the thin plastering heat preservation technology is 20 years, and the service life is reached or approached successively. At the moment, the performance indexes of the insulation board are basically good, and only individual anchoring and bonding systems are no longer suitable for continuous work to form a wall hollowing phenomenon, so that the storage of the buildings is huge, and if the outer wall insulation system is renewed and reworked, the construction is huge, and the resource waste is caused.

Local reinforcement means: on the premise of not dismantling the original building structure system which reaches the design service life, the new technology and the new process are utilized to carry out local transformation treatment, thereby reaching the new standard or the new design requirement.

The existing 'post-anchoring external wall insulation' structural form and construction process at home and abroad:

as shown in fig. 1 and fig. 2, the full-paved anchor-bonding structure comprises from inside to outside:

1) the wall structure a: reinforced concrete structures are abundant, and other structures such as brick walls and block walls exist;

2) pasting mortar b: traditional materials and construction processes;

3) and c, heat preservation nails: the anchoring connecting piece of the heat insulation plate and the wall structure;

(1) c-1: the heat-insulating nail body is generally a hollow plastic piece, so that a cold bridge is avoided;

(2) c-2: a cavity for accommodating an expansion nail c-5 to pass through;

(3) c-3: the anchoring head is provided with expandable threads, and c-5 is extruded into the pointed end of the cavity to expand and gradually cling to the side wall of the pre-drilled wall hole to play an anchoring role;

(4) c-4: the disc base has the function of fixing the insulation board;

(5) c-5: expansion nails: and drilling into the cavity c-2 of the heat-insulating nail, and extruding the heat-insulating nail to expand after entering the anchoring head c-3, so as to realize the anchoring of the heat-insulating nail and the wall body.

4) And (3) insulating layer d: the material and specification are processed and customized according to the design requirements, and the traditional process is adopted;

5) glass fiber net e: the insulation board is bonded, so that gaps of the insulation board are stable and do not expand, and a partial waterproof effect is achieved;

6) finishing layer f: the traditional process is carried out safely according to design.

The technical defects of the existing structural form and process are as follows:

the anchoring force of the heat preservation nail is insufficient:

a) the heat preservation nail is made of: because the heat preservation nail runs through in this insulation board body, for avoiding producing cold bridge phenomenon (be unfavorable for heat retaining heat conduction phenomenon), can only be with the material preparation that material and heated board are close, if: a plastic. The material itself determines the serious shortage of anchoring force.

b) Installing a program: wall body drilling, heated board drilling, insert the heat preservation nail, insert the inflation nail, accomplish in the lump, moreover key pin fin inflation effect operation workman is invisible, belongs to blind operation, and its anchor effect is in doubt.

c) The anchoring mechanism is as follows: the expansion anchoring is required to be made of hard materials such as steel and the like, and only can generate stable and firm anchoring force with a wall body, and the heat-insulating nails are made of flexible materials and are not enough to generate stable and firm anchoring force.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide a local reinforcing device for an external thermal insulation wall surface, which does not need to integrally remove a thermal insulation board, provides a local processing structure for the external wall with simple structure and easy operation, simultaneously realizes reinforcement and repair for the thermal insulation structure of the external wall of a building, and has practicability.

In order to solve the above problems, the specific technical scheme of the utility model is as follows: the utility model provides a local reinforcing apparatus of outer heat preservation wall, includes outer wall, and the heated board has been laid in the relative outside of outer wall, and the glass fiber net has been laid in the relative outside of heated board, and the decorative board has been laid in the glass fiber net outside, and fixedly connected with has the anchor structure who compresses tightly the function on the heated board.

The anchoring structure comprises a ring bottom, the ring bottom is fixedly connected with the outer wall body, the ring bottom is connected with a flange through a supporting column, and the diameter of the flange is larger than the diameter of the outer circle of the supporting column.

And a reserved anchor bolt hole is formed in the ring bottom, and the anchor nail penetrates through the reserved anchor bolt hole to be fixedly connected with the outer wall body.

The support column is of a cavity structure, and a through hole is formed in the side wall of the support column.

The utility model has the following beneficial effects:

local reinforcement and repair are realized, and the problem of overall building safety is solved.

The cost of transformation and maintenance is more economical and practical.
