Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of quasi-static tests on brick masonry walls, and particularly relates to a quasi-static test loading method for polypropylene mesh cement mortar reinforced brick masonry walls. Background Art
[0002] Traditional brick masonry walls often suffer from collapse and cracking due to their inherent poor stability and low bearing capacity. To address this issue, this paper proposes a solution for reinforcing brick masonry walls using a polypropylene mesh cement mortar. To verify the feasibility and effectiveness of this reinforcement solution, pseudo-static tests were conducted.
[0003] Polypropylene mesh cement mortar reinforced masonry wall is a brick wall reinforced with polypropylene mesh with high tensile strength and polymer mortar. It is widely used in construction. During design, construction and acceptance, it is necessary to conduct quasi-static tests on the masonry wall reinforced with polypropylene mesh cement mortar to test its performance and ensure its stable use effect.
[0004] In the prior art, when conducting pseudo-static tests on polypropylene mesh cement mortar reinforced masonry walls, a vertical jack is often used, and the base of the wall is not effectively connected to the foundation beam. This leads to very unsatisfactory test results: the wall rotates around the vertical jack, forming horizontal shear failure along the weak area at the base of the reinforced wall, rather than the ideal "X"-shaped shear failure.
[0005] Therefore, a pseudo-static test loading method for polypropylene mesh cement mortar reinforced brick masonry walls is needed. Summary of the Invention
[0006] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art and provide a pseudo-static test loading method for polypropylene mesh cement mortar reinforced brick masonry walls. This method involves opening a row of through-wall holes parallel to the bottom surface of the wall at the bottom of the reinforced brick masonry wall, opening two rows of rebar holes perpendicular to the bottom surface of the wall on the top surface of the foundation beam, and then planting rebar in the through-wall holes and the rebar holes to form a steel skeleton that binds the reinforced brick masonry wall and the foundation beam together, thereby increasing the integrity of the reinforced brick masonry wall and the foundation beam, ensuring the smooth progress of the pseudo-static test, and preventing the wall from rotating during the repeated pushing and pulling process, which would cause the test to fail. The pseudo-static test data of the reinforced brick masonry wall obtained through the pseudo-static test provides data support for the design, construction, and acceptance of polypropylene mesh cement mortar reinforced masonry walls.
[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: a pseudo-static test loading method for polypropylene mesh cement mortar reinforced brick masonry wall, characterized in that the method comprises the following steps:
[0008] Step 1: Open a row of through-wall holes at the bottom of the polypropylene mesh cement mortar reinforced brick masonry wall to obtain a brick masonry wall with through-wall holes;
[0009] Step 2: Open two rows of rebar planting holes on the top surface of the foundation beam to obtain a foundation beam with rebar planting holes;
[0010] Step 3: Planting rebars in the rebar planting holes of the foundation beam with rebar planting holes obtained in step 2 to obtain a rebar planting foundation beam;
[0011] Step 4: Place the brick masonry wall with through-wall holes obtained in step 1 on the rebar-planted foundation beam obtained in step 3, then plant rebar in the through-wall holes, and then tie the rebar on the foundation beam to the rebar in the brick masonry wall to form a steel skeleton and obtain a rebar-planted structure.
[0012] Step 5: Set a circle of templates higher than the foundation beam outside the foundation beam of the planted reinforcement structure obtained in step 4, then pour grouting material into the space surrounded by the template, and then remove the template after curing to obtain the sample to be tested;
[0013] Step 6: Place the sample to be tested obtained in step 5 under the reaction frame, then install a load-sharing beam on the upper part of the brick wall of the sample to be tested, and then evenly install two jacks on the load-sharing beam, and make the upper parts of the jacks contact the lower surface of the reaction frame beam to obtain the device to be tested;
[0014] Step 7: Perform a pseudo-static test on the device to be tested obtained in step 6 to obtain pseudo-static test data of the polypropylene mesh cement mortar reinforced brick masonry wall.
[0015] The reinforced brick masonry wall of the present invention uses a polypropylene mesh to reinforce both sides to enhance the overall stability of the reinforced brick masonry wall. The present invention opens a row of through-wall holes parallel to the bottom surface of the wall at the bottom of the reinforced brick masonry wall, opens two rows of anchor holes perpendicular to the bottom surface of the wall on the top surface of the foundation beam, and then anchors are planted in the through-wall holes and the anchor holes to form a steel bar skeleton to bind the reinforced brick masonry wall and the foundation beam together, thereby increasing the integrity of the reinforced brick masonry wall and the foundation beam. By arranging a circle of templates higher than the foundation beam on the outside of the foundation beam and then pouring grouting material into the space surrounded by the templates, the reinforced brick masonry wall and the foundation beam bound by the steel bar skeleton are further cast together, which not only protects the steel bar skeleton but also forms a reinforced concrete Soil structure, prevents slippage at the contact surface between the wall and the foundation beam during loading, which leads to test failure. The earth enhances the integrity of the reinforced brick masonry wall and the foundation beam, ensuring the smooth progress of the quasi-static test. The present invention should estimate the physical and mechanical properties of the reinforced brick masonry wall before the quasi-static test, including parameters such as elastic modulus and ultimate bearing capacity. The quasi-static test data of the reinforced brick masonry wall obtained by the quasi-static test is monitored in real time according to parameters such as displacement and deformation of the specimen, and the data is recorded at any time. Finally, the test data is analyzed to obtain the physical and mechanical parameters of the specimen, and the effectiveness of the reinforcement plan is judged to provide data support for the design, construction and acceptance of polypropylene mesh cement mortar reinforced masonry walls.
[0016] It should be noted that the curing time of the present invention is greater than 7 days.
[0017] The above-mentioned pseudo-static test loading method for a polypropylene mesh cement mortar reinforced brick masonry wall is characterized in that, in step 1, the distance between a row of through-wall holes and the bottom of the brick masonry wall is 10cm to 15cm, the interval between adjacent through-wall holes in a row of through-wall holes is 25cm to 30cm, and the aperture of the through-wall holes is 10mm to 12mm. The present invention ensures the binding effect between the steel structure and the foundation beam by controlling the distance between the through-wall holes and the bottom of the wall, prevents insufficient structural strength caused by the through-wall holes being too close to the bottom of the wall and poor fixing effect caused by the through-wall holes being too far from the bottom of the wall, ensures the binding effect between the steel structure and the foundation beam by controlling the interval between adjacent through-wall holes, and controls the aperture of the through-wall holes to minimize the aperture as much as possible while ensuring smooth passage of the steel bars, thereby ensuring the connection effect and the accuracy of the pseudo-static test.
[0018] The aforementioned pseudo-static loading method for a polypropylene mesh cement mortar reinforced brick masonry wall is characterized in that the distance between the two rows of rebar holes in step 2 is equal to the thickness of the brick masonry wall. By controlling the distance between the two rows of rebar holes to be equal to the thickness of the brick masonry wall, the present invention optimizes the structural strength of the reinforcement structure, enhances the integrity of the reinforced brick masonry wall and the foundation beam, and ensures the accuracy of the pseudo-static test.
[0019] The aforementioned pseudo-static loading method for a polypropylene mesh cement mortar reinforced brick masonry wall is characterized in that the spacing between adjacent rebar holes in each row of the rebar holes in step 2 is 25cm to 30cm, the depth of the rebar holes is 10cm to 12cm, and the hole diameter is 10mm to 12mm. This method achieves the desired connection effect by controlling the spacing between adjacent rebar holes and the binding effect of the steel bar structure and the foundation beam, and by controlling the hole diameter of the rebar holes to minimize the hole diameter while ensuring smooth insertion of the rebar, thereby ensuring the connection effect and the accuracy of the pseudo-static test.
[0020] The aforementioned pseudo-static loading method for polypropylene mesh cement mortar reinforced brick masonry walls is characterized by using B8 steel bars and anchoring glue for the anchoring in step 4, with the anchoring depth being no less than 12d, where d is the bar diameter. By controlling the type and depth of the steel bars, the present invention enhances the integrity of the reinforced brick masonry wall and foundation beam, ensuring the accuracy of the pseudo-static test.
[0021] The aforementioned pseudo-static loading method for polypropylene mesh cement mortar reinforced brick masonry walls is characterized in that the strength of the grouting material in step five is no less than C45. By controlling the strength of the grouting material, the present invention enhances the integrity of the reinforced brick masonry wall and foundation beam, thereby ensuring the accuracy of the pseudo-static test.
[0022] The aforementioned pseudo-static loading method for a polypropylene mesh cement mortar reinforced brick masonry wall is characterized in that the formwork in step 6 is positioned along the outside of the foundation beam, with the formwork height exceeding the top surface of the foundation beam by at least 20 cm. By positioning the formwork along the outside of the foundation beam and with the formwork height exceeding the top surface of the foundation beam by at least 20 cm, the present invention allows the grouting material to be completely cast within the reinforced structure, thereby enhancing the integrity of the reinforced brick masonry wall and the foundation beam, and ensuring the accuracy of the pseudo-static test.
[0023] The aforementioned pseudo-static loading method for polypropylene mesh cement mortar reinforced brick masonry walls is characterized by the length of the load-sharing beam in step 6 being greater than the length of the brick masonry wall. By ensuring that the load-sharing beam is longer than the wall length, the present invention ensures that the pressure generated by the jack is evenly distributed across the reinforced brick masonry wall, thereby ensuring the accuracy of the pseudo-static test.
[0024] The aforementioned pseudo-static loading method for a polypropylene mesh cement mortar reinforced brick masonry wall is characterized in that the distance between the two jacks in step 6 is one-third of the width of the brick masonry wall. By controlling the distance between the two jacks to one-third of the width of the brick masonry wall, the present invention positions the two jacks at one-third and two-thirds of the upper portion of the brick masonry wall, respectively, thereby ensuring uniform stress on the brick masonry wall and the accuracy of the pseudo-static test.
[0025] Compared with the prior art, the present invention has the following advantages:
[0026] 1. The present invention opens a row of through-wall holes parallel to the bottom surface of the wall at the bottom of the reinforced brick masonry wall, opens two rows of rebar holes perpendicular to the bottom surface of the wall on the top surface of the foundation beam, and then plants rebar in the through-wall holes and the rebar holes to form a steel skeleton to bind the reinforced brick masonry wall and the foundation beam together, thereby increasing the integrity of the reinforced brick masonry wall and the foundation beam, ensuring the smooth progress of the pseudo-static test, and avoiding the wall from rotating during the repeated pushing and pulling process, which would cause the test failure. The pseudo-static test data of the reinforced brick masonry wall obtained through the pseudo-static test provides data support for the design, construction and acceptance of polypropylene mesh cement mortar reinforced masonry wall.
[0027] 2. The present invention sets a circle of formwork higher than the foundation beam on the outside of the foundation beam, and then pours grouting material into the space enclosed by the formwork, thereby further pouring the reinforced brick masonry wall and the foundation beam tied by the steel skeleton together. This not only protects the steel skeleton, but also forms a reinforced concrete structure, greatly enhancing the integrity of the reinforced brick masonry wall and the foundation beam.
[0028] 3. The present invention controls the distance between the two jacks to be one-third of the width of the brick wall, so that the two jacks are located at one-third and two-thirds of the upper part of the brick wall respectively, thereby ensuring that the brick wall is uniformly stressed and the accuracy of the quasi-static test is ensured.
[0029] 4. The device to be tested of the present invention performs a quasi-static test, which can improve the accuracy of the test, avoid overall slippage of the contact surface, and better realize the loading and monitoring of the reinforced brick masonry wall. The loading effect is very ideal, and a typical "X"-shaped shear failure occurs. It has the advantages of simple operation and low cost, and has broad application prospects.
