Abstract
Description
Technical Field
[0001] The invention relates to the technical field of earthquake resistance and reinforcement of building structures, in particular to a method for reinforcing a raw earth wall of a farmhouse using hollow bricks to wrap the wall. Background Art
[0002] As a traditional building material, earth has become the main building form in the vast rural areas of the region due to its advantages of local materials, convenient construction, thermal insulation, and low cost. However, due to the shortcomings of traditional earth materials such as heavy weight, low strength, and poor integrity, and the rapid decrease in bearing capacity under earthquakes, it is very easy to collapse, resulting in poor durability and earthquake resistance of earth-structured residential buildings. On the other hand, as brick houses have begun to replace traditional earth buildings on a large scale in the construction of existing rural residential buildings, a large number of earth buildings have fallen into disrepair and are on the verge of collapse. Therefore, it is necessary to explore a low-energy consumption, low-cost, easy-to-obtain and easy-to-build earth wall reinforcement technology to better utilize and preserve traditional earth wall buildings.
[0003] When reinforcing an existing wall, in order to ensure the stability of the wall, trenches of specified depth and width are usually dug at both ends of the raw earth wall to pour concrete. Generally, manual or mechanical automatic control equipment is used to dig the trench. Manual digging is inefficient and increases the labor burden. When mechanical automatic control equipment is used to dig the trench, the trench is dug by moving the entire equipment, and it is necessary to ensure that the equipment moves in a straight line. In order to ensure the depth and width of the trench, repeated digging is required, which causes the entire equipment to move back and forth multiple times, resulting in cumbersome operation and easy collision with the wall.

[0046] The present invention aims to propose a method for reinforcing the earthen wall of a farmhouse using hollow bricks, specifically a digging device to speed up the digging of grooves at both ends of the earthen wall and ensure that the dug grooves are always in a straight line. The specific implementation method is as follows:
[0047] In an embodiment of the present invention, a method for reinforcing a raw earth wall of a farmhouse using hollow bricks as the wall is provided.
[0048] Among them, the reinforcement method of the raw earth wall body 39 is shown in Figure 11-13 The construction process can be specifically carried out using the following construction techniques:
[0049] 1. Raw earth wall construction
[0050] A 10 mm deep 200 mm wide groove is dug at both ends of the raw earth wall body 39 using a digging device, so that the newly built brick wall structural column 42 is flush with the surface of the hollow brick wall 40; and a 190 mm high groove is dug at the end of the groove to open up the raw earth wall body 39, facilitating the subsequent construction of the closed ring beam 43.
[0051] 2. Hollow brick wall 40 foundation construction
[0052] Preparation work: Lay out a line and excavate a foundation trench on one side of the raw earth wall body 39, with a foundation burial depth of 500mm. Clean and level the trench, and pour a layer of plain concrete cushion 45 (thickness not less than 70mm, and the cushion concrete strength grade should not be lower than C15).
[0053] Masonry steps: Use the plain concrete cushion layer 45 as the bottom formwork, tie the foundation steel bars 46 (upper and lower double-layer steel mesh) and the foundation beam 47; tie the structural column 42 dowel bars with a cross-section of 200mm*200mm at both ends (the spacing between stirrups should not be greater than 250m, and should be appropriately increased at the upper and lower ends of the column), tie the vertical dowel bars next to the structural column 42 dowel bars as the lap joint of the longitudinal steel bars of the core column 41, and finally pour the foundation concrete.
[0054] 3. Fill the original foundation 49 at the bottom of the raw soil wall
[0055] Preparation: Before masonry, clean the construction site and determine the center line and side line of the original foundation 49 at the bottom of the raw earth wall body. Make sure not to water before masonry, but moisten before laying the blocks.
[0056] Masonry steps: The connection between the wall and the structural column 42 should be built into a tooth joint, starting from the foot of each layer of columns, first retreating and then advancing; follow the masonry principle of "reverse masonry, matching holes, and staggered joints", that is, the bottom surface of each layer of blocks faces upwards, the upper and lower layers of blocks are laid with a length of 195mm, aligned with the holes, and staggered masonry; horizontal tie bars 44 should be set in the mortar joints of the wall adjacent to the structural column 42 for tying, and the tie steel bars should be anchored in the column by not less than 200mm and extend into the wall by not less than 1000mm; there is a cast-in-place ring beam 43 component on the top, and the small blocks on the top skin of the wall should be built upright, and the hollows should be filled with C20 concrete 10 to a height of 140mm in advance, and the remaining 50mm high holes should be cast at the same time as the cast-in-place components.
[0057] 4. Construction of core column 41
[0058] Preparation work: The base of each core column 41 should be built with U-shaped, E-shaped or C-shaped small blocks with cleaning openings; during the construction, the mortar and other debris dropped from the inner wall of the core column 41 hole and the channel should be promptly removed.
[0059] Masonry steps: The longitudinal reinforcement of the core column 41 should be ribbed steel bars, and penetrate into the holes of the small blocks from the top of the wall, and be tied and overlapped with the vertical dowel bars extending from the foundation through the cleaning opening; before pouring the concrete of the core column 41, a 50mm thick cement mortar with the same composition as the concrete for pouring the holes and without coarse aggregate should be poured first; the concrete 10 of the core column 41 should be operated according to the principle of continuous pouring and layered compaction, and should be poured until it is 50mm away from the top surface of the uppermost small block of the core column 41, and no construction joints should be left.
[0060] 5. Construction of structural column 42
[0061] Preparation work: The formwork on both sides of the structural column 42 must be close to the wall and no mortar should leak; a 100mm*200mm cleaning opening should be reserved at the bottom of the column formwork, and mortar and other debris should be removed and the formwork should be moistened with water.
[0062] Masonry steps: First inject 50mm thick cement mortar with the same composition as concrete 10 and no coarse aggregate, then pour and vibrate the concrete in layers until completion.
[0063] 6. Construction of ring beam 43
[0064] Preparation work: The cross-section of the cast-in-place concrete ring beam 43 is 200mm*200mm, located at the top of the wall, and tied and connected with the structural column 42 and the core column 41.
[0065] Masonry steps: After the hollow brick wall 40 is completed, a closed ring beam 436 is tied to the top of the wall, and finally C20 concrete 10 is poured to fill it.
[0066] It should be noted that after the reinforcement of the core column 41, the structural column 42 and the ring beam 43 is tied, the cast-in-place concrete 48 is poured as a whole; the hollow brick walls 40 on both sides of the raw earth wall body 39 are built parallel to and adjacent to the raw earth wall body 39 in a certain order, and both sides cannot be built at the same time.
[0067] It should be noted that when the wall length exceeds 5m, the structural column 42 is reserved according to the specification requirements, so the raw earth wall body 39 with a length of 5.4m is selected as a unit object as an example of the reinforcement scheme;
[0068] Select single-row hole ordinary concrete small hollow blocks with specifications of 390mm*190mm*190mm and strength grade of MU10.
[0069] Among them, the strength grade of the cast-in-place concrete 10 should not be lower than Cb20, which is equivalent to the corresponding concrete strength grade C20.
[0070] Preferably, the longitudinal reinforcement of the structural column 42 should not be less than 4φ12.
[0071] Preferably, the vertical dowel of the core column 1 should not be less than 1φ12.
[0072] Preferably, the minimum longitudinal reinforcement of the cast-in-place concrete ring beam 43 is 8 degrees 4φ12, the maximum spacing of the stirrups is 8 degrees 200mm, and the diameter of the stirrups should not be less than φ6.
[0073] Preferably, the horizontal tie bars 44 provided in the mortar joints of the wall adjacent to the structural column 42 should not be less than 2Ф6, and should be anchored in the column by not less than 200 mm and extend into the wall by not less than 1000 mm.
[0074] See also Figure 2 ~ and Fig.10, wherein a method for reinforcing a raw earth wall of a farmhouse using hollow bricks comprises a digging device, the digging device comprises a mobile trolley 1 and a parallel connecting rod assembly arranged on the mobile trolley 1, the parallel connecting rod assembly is connected to a slide plate 7 slidably arranged on the mobile trolley 1, and the slide plate 7 is controlled to be able to move relative to the mobile trolley 1;
[0075] It also includes a grooving mechanism disposed on the slide 7, the grooving mechanism including a bucket 20 and an adjusting member disposed between the bucket 20 and the slide 7, the adjusting member being capable of changing a grooving angle of the bucket 20;
[0076] The gap driving member is arranged on the moving vehicle 1 and is respectively connected to the parallel connecting rod assembly and the adjusting member.
[0077] In detail, when the foot of the raw earth wall at one end is ready to be excavated, the gap drive is started to drive the parallel connecting rod assembly to perform a reciprocating swinging motion, and drive the slide plate 7 to move relative to the moving trolley 1. When the slide plate 7 moves, the bucket 20 excavates the foot of the wall, and when the slide plate 7 moves to the end of the stroke, the parallel connecting rod assembly stops the swinging motion. Driven by the gap drive, the adjusting member works to drive the bucket 20 to complete a set of reciprocating lifting and lowering actions, and in the process of rising, the opening direction of the bucket 20 is deflected to ensure that when the bucket 20 performs the digging action, the opening direction of the bucket 20 is always consistent with the moving direction, thereby further improving the digging efficiency of the trench, and the bucket 20 is always in a straight line during the digging process to prevent collision with the raw earth wall and secondary damage to the raw earth wall.

The first supporting frame 101 and the second supporting frame 102 are provided mainly to avoid interference between the parallel connecting rod assembly and the gap driving member on the moving trolley 1 when performing a swaying action.
[0080] Specifically, driven by the gap driving member, the first deflection axis 2 deflects, and according to the parallelogram principle, the first connecting rod 4 and the second connecting rod 5 deflect synchronously, driving the connecting plate 6 to swing in a circle. When the connecting plate 6 swings, the boss 601 thereon squeezes the slide plate 7.
