It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.

[0024] Some unique regional style ancient town building group, its outer surface of the red brick or green brick wall, exquisite workmanship, historical traces of sedimentation, eye-pleasing, has a high value of cultural relics. But because of the construction of long time, there is unreasonable building layout, water, electricity and heating facilities are simple, live in, extremely inconvenient, and the ancient town building is basically brick and concrete structure, the floor steel corrosion is serious, the bearing capacity and seismic resistance of the main structure is poor.

[0025] The traditional transformation mode is reinforcement. In the case of not changing the original building layout, reinforce the masonry bearing wall and floor to achieve the purpose of continuing to live safely. The traditional transformation mode is subject to the original building layout, cannot change the size space, and cannot take into account the change of the use function demand of the building in different years. Moreover, the old building reinforced by the traditional way, due to the lack of old building data, its seismic performance after reinforcement is difficult to calculate accurately.

[0026] Based on this, as shown in Figure 1 Figure 4 The embodiment provides a brick and concrete house transformation and reinforcement structure, which comprises a masonry outer wall 5, a foundation beam 1 arranged at the bottom of the inner and outer sides of the masonry outer wall 5, a unloading beam 2 arranged at the bottom of the masonry outer wall 5, wherein the unloading beam 2 transversely penetrates the masonry outer wall 5 and is connected with the foundation beam 1, and a cement mortar surface layer 6 arranged on the inner side of the masonry outer wall 5; a structural column 7, which penetrates each floor slab and extends to the bottom of a roof slab, wherein a strip foundation 3 is arranged at the bottom of the structural column 7; a structural beam slab 8, which is arranged on each layer, wherein the end of the structural beam slab 8 is connected with the structural column 7 or the masonry outer wall 5, the end of the structural beam slab 8 connected with the masonry outer wall 5 is provided with a buttress 9, and the buttress 9 extends downward to the foundation beam 1 along the masonry outer wall 5.

[0027] ​The base beam 1, the unloading beam 2, the structure column 7 and the structure plate beam are all reinforced concrete. Specifically, the reinforced concrete base beam 1 is newly added on both sides of the masonry outer wall 5 to widen the masonry outer wall 5 and enlarge the foot foundation, the reinforced concrete base beam 1 and the enlarged foot foundation of the masonry outer wall 5 are connected by using the plum-blossom-shaped planting steel bar Φ14@500x500, and the reinforced concrete unloading beam 2 with a size of 200X500 is evenly spaced (every 1.5m) and arranged to cross the enlarged foot foundation of the masonry outer wall 5, and is anchored into the newly added reinforced concrete base beam 1 on both sides of the masonry outer wall 5, so that the newly added reinforced concrete base beam 1 and the enlarged foot foundation of the masonry outer wall 5 bear the force cooperatively. The inner side of the masonry outer wall 5 is reinforced by using the 100-thick cement mortar surface layer 6, the Φ10@150 bidirectional steel mesh net is arranged in the cement mortar surface layer 6 and connected with the masonry outer wall 5, and the plum-blossom-shaped planting steel bar Φ10@300x300 can also be used to make the two bear the force cooperatively.

[0028] During the construction, the inner partition wall and the floor of each layer of the building need to be removed, and the structure beam plate 8 of each layer of frame is newly built; before the removal of the partition wall of each layer and the construction of the floor of each layer, the newly added structure column 7 (including the base) is continuously penetrated through the floor of each layer and is constructed to the bottom of the roof plate. It is necessary to pay attention to the beam reinforcement at the joint of each layer of beam and column. The structure beam plate 8 is newly built on the floor of each layer, the end of the structure beam plate 8 is connected with the structure column 7 or the masonry outer wall 5, the newly built structure beam plate 8 and the structure column 7 form a newly built frame structure. The position where the structure beam plate 8 is connected with the masonry outer wall 5 is provided with a buttress column 9, the buttress column 9 extends downward to the base beam 1 along the masonry outer wall 5, the unloading beam 2 with a size of 300X500 is arranged below the buttress column 9 to cross the enlarged foot foundation of the masonry outer wall 5 and is anchored into the newly added reinforced concrete base beam 1 on both sides of the masonry outer wall 5, so that the axial force of the buttress column 9 is uniformly transmitted to the base.

[0029] Further, at the position of the base beam 1 of the masonry outer wall 5, an overhanging bottom plate 10 can be arranged to increase the stress area of the base.

[0030] Further, the top of the newly added structure column 7 adopts a strip foundation 3, and a hidden beam 4 is arranged in the strip foundation 3 to enhance the integrity of the structure base.

[0031] Based on the above embodiment, the present embodiment further provides a construction step, and the steps are as follows:

[0032] Step one: support the floor of each layer and the roof and set the peripheral outer wall support. The peripheral outer wall support needs to be calculated and confirmed, and the weakening of the stability and bearing capacity of the masonry outer wall 5 during the construction process, when the floor of the middle layer is removed and the new floor structure is not poured, is fully considered.

[0033] Step two: reinforce the base of the masonry outer wall 5 and reserve the post-poured belt when the inner partition wall of the first layer hinders. The reinforcement of the base of the masonry outer wall 5 needs to be calculated and confirmed.

[0034] Further, the foundation beam 1 is newly added on both sides of the masonry outer wall 5 to widen the foundation of the masonry outer wall 5, and the foundation beam 1 is planted with the Φ14@500x500 bolt between the foundation of the masonry outer wall 5.

[0035] Further, the unloading beam 2 with the size of 200X500 is arranged every 1.5m to cross the masonry outer wall 5 to enlarge the foot foundation, and the unloading beam 2 is anchored into the newly added foundation beam 1 on both sides of the masonry outer wall 5, so that the newly added foundation beam 1 and the foundation of the masonry outer wall 5 bear the force cooperatively.

[0036] Step three: the newly added structural column 7 (including the strip foundation 3 and the hidden beam 4) is constructed to the bottom of the roof floor.

[0037] Further, the newly added structural column 7 needs to penetrate through the floor of each layer, and the beam rib at the beam column joint of each layer needs to be reserved, and the original structure floor back support needs to be paid attention to.

[0038] Step four: the roof floor is removed and the structural beam plate 8 is constructed according to the cast-in-place concrete structure, and the reinforcing rib for the outer wall reinforcement needs to be reserved.

[0039] Step five: the uppermost masonry outer wall 5 is reinforced, and the construction post-pouring belt is reserved at the original inner partition wall, and after the masonry outer wall 5 is reinforced, the inner partition wall of this layer is removed, and the post-pouring belt of the outer wall is closed. Similarly, steps four and five are sequentially performed downwards until the first layer outer wall is reinforced and the first layer inner partition wall is removed.

[0040] Step six: the inner partition wall of each layer and the pipe well equipment are constructed according to the new building layout.

[0041] The above is only used for describing the implementation mode of the utility model, and is not used for limiting the utility model, and any modification, equivalent replacement, improvement and the like made by the skilled in the art without creative labor within the spirit and principle of the utility model should be included in the protection scope of the utility model.
