Description
Technical Field
The invention relates to the technical field of ancient building reinforcement, in particular to a blue brick wall reinforcement device and a construction method thereof.
Background
The reinforcing of green brick wall body of ancient building among the prior art has the fresh concern, then can't really provide a universal application and effective technical scheme all the time to rectifying of green brick wall body of ancient building, and just will rectify and consolidate the technical scheme who organically combines yet to propose to green brick wall body of ancient building.
The prior technical scheme is summarized from practical experience and mainly aims at wall body rectification, does not relate to the reinforcement of the wall body, and is difficult to reinforce while slightly rectifying compared with the original construction conditions without special equipment. The specific description is as follows:
the method comprises the steps of drilling a hole in the protruding portion of the deformed wall body, pressing a steel plate on the protruding portion, enabling a threaded iron rod to penetrate through the wall body, enabling one end of the threaded iron rod to be connected with the steel plate, enabling the other end of the threaded iron rod to be connected with a flexible cable, installing a support on the indoor ground, enabling the flexible cable to be connected to the support, pulling the steel plate through rotation of a basket screw, and pulling the deformed portion of the.
The scheme has obvious problems in the deviation rectifying process: firstly, the deviation rectifying process is complex, and the traction direction is very inconvenient to change. The angle of the steel plate pulled by the flexible cable is fixed, but the deformation angle of the wall body is changed frequently, so that a constructor needs to drill holes again on the ground and install the flexible cable straightening devices and supports if the pulling direction of the flexible cable is changed, and the step needs to be repeated every time the angle is adjusted.
Secondly, the ancient building green brick wall body suitable for this scheme is few. The whole wall body is pulled to be straight through a plurality of stress points, the maintenance condition of the wall body is required to be good, the wall body is firmer, and otherwise, a smaller stress area can collapse firstly under the pulling. Finally, the threaded iron rod penetrates the wall body, and irreversible damage can be caused to the wall body. Therefore, the method is not suitable for most ancient building walls which are worried and urgently need reinforcement and protection.
On the basis, the following technical scheme is improved as follows and becomes the prior technical scheme. The improved technical scheme focuses on uniformly fixing and righting the whole wall, reduces damage to the wall body, and does not relate to the problem of reinforcing the deformed wall body. The improved technical scheme is described as follows:
engineering technicians manufacture a well-shaped formwork which is respectively positioned at two sides of the wall body, and iron wires penetrate through the wall body and then bind the well-shaped supporting formwork at the two sides of the wall body to wrap the wall body. The steel cable fixing devices are respectively installed on the indoor ground and the outdoor ground, the steel cable tightening devices are additionally arranged, one ends of the steel cable tightening devices are connected with the steel cable fixing devices, the other ends of the steel cable tightening devices are connected to the # -shaped formwork, and the whole wall is further righted from an inclined state by adjusting the steel cable tightening devices on the two sides of the wall.
The outstanding problems with this solution are: firstly, the scheme can only be applied to the wall body which basically has no deformation and is inclined to some extent, otherwise, the wall body can not be completely wrapped by two # -shaped formwork. That is, complete and close wrapping of the wall inevitably requires first solving the wall deformation, and the method does not mention how to correct the deviation. Secondly, in order to ensure that the wall body can be effectively pulled, the number of the steel cable fixing devices arranged on the ground is large, and the indoor ground cannot withstand the intensive construction. Thirdly, in order to fix the # -shaped formwork on the wall body, the wall body is penetrated by iron wires densely, and the damage to the strength of the wall body is obvious. Moreover, the ancient buildings should protect the indoor ground as much as possible besides the cultural relic value of the wall. Finally, this solution lacks an effective angle measuring tool, and the drop hammer cannot accurately provide measurements of complex angles.

101. the reference device is positioned on one side of a wall body depression, the surface of the reference steel plate 1 is covered with the flexible air bag 2, and the reference steel plate 1, the flexible air bag 2 loaded on the reference steel plate and the air pressure detection device 3 are lifted to a wall body deformation part through the machine body 10 and the posture adjusting unit 9. The reference steel plate 1 provides a deviation-rectifying reference plane for the deformed wall body by utilizing the correction of the self angle and height.

Under the condition, the construction difficulty caused by the fact that the deformation angle of the deformation wall body is easy to change is effectively solved, and the relative angle of the reference steel plate 1 can be flexibly adjusted in the process of construction in the face of complex deformation. Compared with the prior art, the technical scheme that a reference plane is not set, and only the righting rod is used for applying pressure to the single side of the wall body to enable the wall body to return, or a scaffold, a # -shaped supporting module and the like are not convenient to adjust according to the deformation condition of the wall body, and the technical scheme that the reference pressing plate 1 is adjustable is obviously controllable, reliable and wide in application range.
As shown in fig. 2, the propulsion device in the present embodiment is a method 200 for rectifying and strengthening a wall, and is used for rectifying and strengthening a wall organically integrated process. In the implementation, the method comprises the following steps:
201. the pushing pressing plate 4 is lifted to the deformation part of the wall body through the mechanical body 10 and the posture adjusting unit 9, the construction difficulty caused by the deformation angle and height of the deformation wall body can be solved by using the method, and the complex deformation of the blue brick wall body can be flexibly adjusted by adjusting the relative angle of the pushing pressing plate 4.

202. The attitude of the pushing platen 4 is adjusted with reference to the angle measurement value of the reference steel plate 1, and is finely adjusted to a reasonable position by the attitude adjusting unit 9 on the pushing platen 4 side.
203. The injection probe 5 is assembled according to the position of the brickwork joint, new cement is injected into the flexible rubber container 6, and the injection probe 5 and the flexible rubber container 6 are connected by a hose 7. Wherein, the flexible rubber container 6 has good toughness and pressure resistance and can contain enough cementing materials. In this step, the pushing platen 4, in addition to pushing the convex portion of the deformed wall to a flat state, also serves as a carrier for the means for simultaneously injecting cement, i.e. carries the injection probe 5, the flexible rubber container 6 and the hose 7. In order to realize the carrier function, the pushing pressing plate 4 is uniformly distributed with a plurality of installation bases of the injection probes 5 on the plane, and the processing positions of the installation bases of the injection probes 5 are referred to the thickness of the wall of the historic building so as to be accurately wedged into the brick joints of the wall.
204. The hydraulic driving device 12 pushes the pressing plate 4 to move to a target position, the wall body is synchronously corrected and reinforced, the phenomenon and condition that the wall body crushes solids formed by yellow mud and lime slurry in a wall gap in the process of restoring the wall body to be straight under the action of external force are utilized, cementing materials are synchronously injected through the flexible rubber container 6 and the injection probe 5 when the protruding part of the wall body is pushed to be straight, and three links of correcting the deformation part of the wall body, strengthening the strength of the wall body 11 and protecting the wall body 11 are solved in the same flow. The reference steel plate 1 and the pushing pressure plate 4 are still kept in a clamping state after the injection is finished until the cementing materials are really coagulated.
205. After the cementing material is solidified and the wall body recovers certain strength, the reference steel plate 1 and the pushing pressing plate 4 can be withdrawn along the direction vertical to the wall body.
In this case, after the method for synchronously injecting the cementing material is implemented, the cementing material is considered to be reinforced from the inside when solid fragments formed by yellow mud, lime slurry and the like inherent in the wall body of the grey brick of the historic building are re-coagulated and provide better bearing for the wall body. This setting time is obtained by the previous test of equivalent materials and is generally 2-3 hours to complete the setting.
So far, the bulge of wall body is restored to straight state under the combined action of benchmark device and advancing device, and the cement material that pours into again increases the intensity of ancient building blue and white brick wall body, rectifies and consolidates and accomplishes in a flow.
