Abstract
An external prestress reinforcement device for a diagonal brace of masonry wall body is characterized in that a screw rod 2 is mounted in a hole 1 on a beam 6, a steel plate 3 is hung on the screw rod 2, an element 4 with the function of prestress support is arranged on the steel plate 3, the diagonal brace 5 threaded on the two ends penetrates the element 4, and screw caps for tensioning the diagonal brace 5 are arranged thereon. By virtue of the rigidity of the wall body, the horizontal component of a steel bar directly resists the shearing force transmitted to the wall body; the vertical component force of the tension of the steel bar increases the axial force of the wall body, thereby facilitating the increase of the anti-shearing force of the wall body; the dead weight of the original structure is by no means remarkably increased; moreover, the technology is simple, and the application is convenient.
Description
Technical field
The utility model relates to and a kind of the existing body of wall of civil engineering is applied prestressing force, thereby strengthens the reinforcing technique field of its shear resistance, especially relates to a kind of masonry panel brace external prestressing strengthening device.
Background technology
At present, the reinforcing technique to masonry adopts the two-sided grey method of touching more.Two-sided technical essential of touching ash is: at first root out the original grieshoch of touching of body of wall, secondly both sides hang steel fabric sheet (or reinforced mesh) inside and outside body of wall, and with steel fabric sheet (or reinforced mesh) drawknot through walls of both sides inside and outside the body of wall, touch ash in the body of wall both sides with the higher mortar of strength grade then and handle, can finish reinforcing body of wall.
The shortcoming of this reinforcing technique is: 1) the dead load value added is big, reinforcement measure to the recruitment of body of wall deadweight generally the body of wall deadweight 20%～25% between.The ground subsidiary stress increases, and can cause new uneven settlement of foundation.2) engineering quantity is big.
So there is the suspicion of having reinforced body of wall and having destroyed ground in original wall reinforcement technology.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of masonry panel brace external prestressing strengthening device is provided, thereby effectively solves the problems of the prior art.
The purpose of this utility model is by realizing by the following technical solutions: described masonry panel brace external prestressing strengthening device, be characterized in: in the hole 1 on the figure beam 6 of described masonry panel screw rod 2 is installed, steel plate 3 is mounted on the screw rod 2, steel plate 3 is provided with the element 4 of band prestressing force supporting role, two is opened the brace 5 of silk and is passed element 4, and brace 5 is provided with the nut that is used to strain brace 5.
The beneficial effects of the utility model are: described masonry panel brace external prestressing strengthening device, and by means of the rigidity of body of wall, the horizontal component of reinforcing bar is directly resisted the body of wall transfer shearing force; The vertical force component of reinforcing bar pulling force has increased the axle power of body of wall, helps to increase the shear resistance of body of wall; Significantly do not increase the original structure deadweight; Technology is simple, is convenient to use.
Description of drawings
Fig. 1 is a structural principle schematic diagram of the present utility model.
Specific implementation
As shown in Figure 1, 2, described masonry panel brace external prestressing strengthening device, be characterized in: in the hole 1 on the figure beam 6 of described masonry panel screw rod 2 is installed, steel plate 3 is mounted on the screw rod 2, steel plate 3 is provided with the element 4 of band prestressing force supporting role, two is opened the brace 5 of silk and is passed element 4, and brace 5 is provided with the nut that is used to strain brace 5.
Described masonry panel brace external prestressing strengthening device, it at first prepares member when implementing, comprise screw rod 2, steel plate 3, support component 4 and welding thereof, brace 5 and corresponding nut.Locate setting-out then.Perforating 1 again, wear screw rod 2, hang the steel plate 3 of weld support element 4, the body of wall bilateral symmetry is placed brace 5, and swivel nut applies prestressing force to body of wall.
