Abstract
The utility model discloses a seismic strengthening structure of a retained exterior wall. The structure is characterized by comprising a strengthened wall body cast inside the retained exterior wall, wherein the strengthened wall body is internally provided with a two-way reinforcement fabric slice layer; the inside of the retained exterior wall is provided with openings at intervals; the opening is pre-cast with an anchor bar; and the strengthened wall body and the inner side of the retained exterior wall are connected into a whole in a manner of combed scrubbing. By adopting the manner of combed scrubbing, the strengthening structure causes the newly built strengthened wall body, beams, columns and other structures to be connected with the retained exterior wall into a whole, thus achieving the purpose of seismic strengthening of old walls needing to be retained. Due to the action of combed scrubbing and the anchor bar, the newly built reinforced concrete structure is caused to be connected with the old walls tightly to achieve the effect of strengthening the old wall. The method is simple in operation, small in implementing difficulty and economical, saves cost and does not damage the old walls.
Description
Technical field
The utility model relates to a kind of protection external wall reinforcing technique, specifically discloses a kind of preserved building exterior wall seismic reinforcing structure.
Background technology
The exterior wall of general protection building is built into by brick wall; and because existing intensity is lower; can't satisfy the antidetonation grade that existing earthquake resistant code requires; in order to make old building recover function of use and " restoring the old as the old " again; the old building exterior wall is not removed and kept its outer elevation appearance; so must take the measure of corresponding structure reinforcing technique that it is carried out seismic hardening, satisfy following function of use.
Present existing exterior wall reinforcing technique mainly contains: exterior wall is carried out steel bonding, carbon fiber reinforcement or two-sided employing gauze wire cloth whitewash mortar technology; the reinforcing or the cost of these forms are higher; the perhaps low requirement that does not have seismic hardening of fastening strength grade will destroy again or to the protection exterior wall.Therefore existing exterior wall reinforcing technique can't satisfy the needs of protection external wall repairing and reinforcement.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of reparation that both can realize protecting exterior wall, can satisfy the reservation exterior wall seismic reinforcing structure of seismic hardening requirement again, thereby overcomes the above-mentioned defective that prior art exists.
The technical scheme of the utility model technical solution problem is as follows:
A kind of reservation exterior wall seismic reinforcing structure, it is characterized in that, comprise and be cast in the reinforcement body of wall that keeps inner side of outer wall, two-way concrete slab net lamella is set in the described reinforcement body of wall, described reservation inner side of outer wall is interval with the hole, pre-buried dowel in the hole, described reinforcement body of wall fuses by gingival cyst of mucous gland in the newborn stranding mode with the reservation inner side of outer wall.
Preferably, also comprise the frame column that is provided with at interval, frame column is arranged on to be strengthened in the body of wall, and fuses by gingival cyst of mucous gland in the newborn stranding mode with the reservation inner side of outer wall.
Preferably, also be included in one reinforced concrete circle beam that each floor outer ring is provided with, described concrete ring beam is arranged on to be strengthened in the body of wall, and fuses by gingival cyst of mucous gland in the newborn stranding mode with the reservation inner side of outer wall.
The thickness of described reinforcement body of wall is 80mm～120mm.
By above disclosed technical scheme as can be known, the utility model is by adopting outside keeping opening holes within the walls, pre-buried dowel in the hole, and build the reinforcement body of wall outward within the walls, the mode that reinforcement body of wall and reservation exterior wall are rubbed with the hands by gingival cyst of mucous gland in the newborn connects as one, further can also be by the mode that frame column and each floor outer ring are provided with reinforced concrete circle beam is set at a certain distance, structures such as strengthening body of wall, beam, post is held together with keeping exterior wall, thereby reach the seismic hardening purpose of the old body of wall that need are kept.
Because the effect that gingival cyst of mucous gland in the newborn is rubbed with the hands makes that newly watering reinforced concrete structure tightly links to each other with old body of wall, reaches the reinforcement effect to old body of wall under the effect of gingival cyst of mucous gland in the newborn stranding and dowel, this practice is simple to operate, the implementation difficulty is little, and economic and saving cost more can not produce old body of wall and destroy.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, 2, the utility model keeps the exterior wall seismic reinforcing structure, comprise and be cast in the reinforcement body of wall 2 that keeps exterior wall 1 inboard, two-way concrete slab net lamella 21 is set in the described reinforcement body of wall 2, described reservation exterior wall 1 clear width is provided with hole 11, pre-buried dowel 3 in the hole, described reinforcement body of wall 2 is rubbed 6 with reservation exterior wall 1 inboard with the hands by gingival cyst of mucous gland in the newborn and is fused.Described reinforcement body of wall 2 is the thick C30 pea gravel concreten body of wall of 100mm.
Shown in Fig. 3,4, also comprise the frame column 4 that is provided with at interval, frame column 4 is arranged on to be strengthened in the body of wall 2, and fuses by gingival cyst of mucous gland in the newborn stranding 6 with reservation exterior wall 1 inboard.
Shown in Fig. 5,6, also be included in one reinforced concrete circle beam 5 that each floor outer ring is provided with, described concrete ring beam 5 is arranged on to be strengthened in the body of wall 2, and fuses by gingival cyst of mucous gland in the newborn stranding 6 with reservation exterior wall 1 inboard.
To historical protective buildings, need keep the most of zone of exterior wall by designing requirement, and will replace the old brick mix structure in inside, form new frame construction.So need on the basis that keeps foreigner's wall, make the old and new's structure form an integral body.Specific implementation method:
