Abstract

The invention relates to the technical field of fixed buildings, in particular to a gravity type damping filling wall which comprises a frame structure, two brickworks arranged in the frame structure side by side, and prestress ribs located on the two sides of the two brickworks and crossed at the diagonal position of the frame structure. A steel groove support is arranged below each brickwork. The two ends of each steel groove support are connected with the ground through opposite supporting legs respectively. Slide grooves are formed in the supporting legs. V-shaped supports are arranged between every two opposite supporting legs. The two ends of each V-shaped support are arranged in the slide grooves of the corresponding supporting legs on the two sides. Slide wheels are arranged at the bottom ends of frame columns of the frame structure. The top ends of the prestress ribs are fixed to the upper portion of the frame structure. The bottom ends of the prestress ribs are wound around the slide wheels and fixed to the middles of the V-shaped supports on the corresponding sides. By stretching or releasing the prestress ribs, the field angles of the V-shaped supports are changed. The two brickworks in the frame structure deform in the lateral direction of the frame structure so as to vertically and oppositely move, and therefore energy consumption happens to a damping medium in the filling wall, and the risks of cracking breakage and plane outward collapse of the filling wall are reduced.

For making the purpose of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the premise not making creative work, broadly fall into the scope of protection of the invention.
As shown in Figure 1, a kind of gravity type damping infilled wall that the embodiment of the present invention provides includes standing on the frame structure 1 on ground, the first masonry 21 being arranged side by side being filled in frame structure 1 and the second masonry 22 and being positioned at two panels masonry both sides and the presstressed reinforcing steel intersected in frame structure 1 diagonal positions, the top of presstressed reinforcing steel is the first presstressed reinforcing steel 31 near the first masonry 21, the top of presstressed reinforcing steel is the second presstressed reinforcing steel 32 near the second masonry 22, and the both sides of masonry are equipped with the first presstressed reinforcing steel 31 and the second presstressed reinforcing steel 32 crossed one another;Steel tank support it is equipped with below every masonry, it it is the first steel tank support 41 below first masonry 21, being the second steel tank support 42 below second masonry 22, the two ends of the first steel tank support 41 and the second steel tank support 42 are connected with ground by the leg 5 being oppositely arranged respectively; Concrete, in the present embodiment, the first steel tank support 41 and the second steel tank support 42 all can be connected with ground by multipair leg 5. Being equipped with chute on each leg 5, be provided with V-type and support 6 between two relative legs 5, V-type supports the two ends of 6 and is respectively arranged in the chute of both sides leg 5, is used for supporting steel tank support and moves up and down; Concrete, in the present embodiment, V-type supports the bottom of 6 and is fixed on ground, and V-type supports the top of 6 and can slide up and down along chute. Frame structure 1 includes the Vierendeel girder 11 at top and the frame column 12 of both sides, and the bottom of frame column 12 is provided with pulley 13, and the bottom of frame column 12 is it can also be provided that rolling bearing; The top of frame structure 1 is fixed on the top of presstressed reinforcing steel, the middle part that pulley 13 is fixed on the V-type support 6 of this side is walked around in the bottom of presstressed reinforcing steel, the subtended angle of 6 is supported by the mobile change V-type of presstressed reinforcing steel, preferably, the top of the first presstressed reinforcing steel 31 is fixed on the first masonry 21 side frame column 12 and Vierendeel girder 11 intersection, and the bottom of the first presstressed reinforcing steel 31 is walked around the pulley 13 of frame column 12 bottom of the second masonry 22 side and is connected with the middle part of two V-types supports 6 below the second masonry 22; The top of the second presstressed reinforcing steel 32 is fixed on the intersection of the second masonry 22 side frame column 12 and Vierendeel girder 11, the bottom of the second presstressed reinforcing steel 32 is walked around the pulley 13 of frame column 12 bottom of the first masonry 21 side and is connected with the middle part of two V-types supports 6 below the first masonry 21, in the present embodiment, the angle that V-type supports 6 is set to 90 ��.
When load action to the right there is lateral deformation to the right in framework, second presstressed reinforcing steel 32 is stretched, causing the angle that the V-type bottom the first steel tank support 41 supports 6 to increase, the angle that the first steel tank support 41 supports 6 due to this V-type increases and upwards lifting, i.e. the first masonry 21 upwards lifting. Meanwhile, the first presstressed reinforcing steel 31 is relaxed, and the V-type of the second steel tank support 42 lower end supports the angle of 6 and reduces, the second steel tank support 42 pan-down therewith, i.e. the second masonry 22 pan-down. Similarly, when load action to the left there is lateral deformation to the left, the first masonry 21 pan-down, the second masonry 22 upwards lifting in framework. Provable by calculating, when there is the horizontal comparison of 1 unit in framework, the relative sidesway between two panels body of wall can reach 1.66 units.

It is equipped with damping layer 7 between sidewall and the frame column 12 of two panels masonry. The damping layer 7 of masonry and frame column 12 support is possible not only to deformation power consumption, additionally it is possible to offset the Incoordinate deformation between framework and brickwork, it is to avoid the horizontal shear failure of infilled wall. Damping layer 7 adopts elastomeric material to make. It should be noted that damping layer 7 is not limited to elastomeric material, it is also possible to be the material of other energy that can dissipate such as foam cement brick.
In sum, gravity type provided by the invention damping infilled wall stretches due to presstressed reinforcing steel or loosens rising or falling of the first masonry 21 caused and the second masonry 22, the stretcher strain of 1 two diagonals of frame structure and compression are converted the detrusion between for two panels masonry simultaneously, part seismic energy is converted to the damping energy dissipation of damping layer and is lifted the gravitional force of masonry, the energy of earthquake of significantly having dissipated. Meanwhile, it is inharmonious that the damping material between two panels masonry, between masonry and framework can also deform between cushioning frame structure and masonry, reduces the risk of infilled wall cracking failure. It addition, be positioned at masonry both sides presstressed reinforcing steel arranged in a crossed manner except the effect with drawknot, it is also possible to prevent from toppling outside the plane of masonry. The simple structure of the gravity type damping infilled wall of the present invention, it is simple to construction application.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit; Although the present invention being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
