Description

TECHNICAL FIELD

[0001] The present application relates to the field of building construction technology, in particular to a forming method of rammed earth city wall and an auxiliary formwork thereof. BACKGROUND

[0002] The rammed earth city wall is an ancient civil composite structure with layered compacted soil as the core, and is formed by formwork setting, layered ramming to form a vertical load-bearing system. It is a wall structure made of natural soil materials (such as clay, sand, etc.) through compaction process. It is an ancient and environmentally friendly building method, and is usually used in traditional buildings, especially in some areas with rich natural resources and poor transportation. The rammed earth wall is unique in construction method, durability and low cost. There are mainly two types of traditional rammed earth formwork: the first type is made of three wooden boards, the two side formworks are about 1.5 meters long, the width of the end baffle is the same as the wall thickness, the side formworks are clamped by detachable wooden sticks, the side formworks and the end baffle are connected by mortise and tenon and clamped, and the height of the formwork is generally 30-33 cm. The wall built by using this formwork is usually called "boarded wall". The second type is to replace the two side wooden formworks with round logs with smooth and straight surfaces. Generally, there are 3-5 round logs on each side. When a layer of ramming is completed, the lowermost round log is turned up and fixed, and the same method is used to continue ramming, and the process is repeated one by one. The wall built by using this formwork is called "rafter wall".

[0003] In the prior art, the aluminum formwork of the rammed earth city wall is usually composed of side plates, baffle plates, clamping sticks and hoop heads. In the specific operation process, the side plates and the baffle plates are first placed on the foundation to form a rectangular mold for limiting the shape and size of the rammed earth, then the formwork is fixed to prevent displacement or deformation during the ramming process, then the soil is filled in layers in the formwork, each layer is about 15 cm thick, and the compaction equipment is used to compact each layer of soil to ensure the compactness. After compaction, the formwork is moved along the direction of the city wall to continue ramming the next section until the required length is reached. In the specific operation process, before the formwork is moved, the workers usually place support components in the city wall to support the bottom of the moved formwork. As the height of the rammed earth city wall increases, when the formwork needs to be moved to continue ramming the next section after compaction, due to the high height and narrow width of the city wall, the moved formwork is inclined downward due to its own gravity, and there is a certain safety risk in moving the large formwork at a high altitude.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0038] Please refer to Figures 1-15 The present application provides a technical solution: a forming method of rammed earth city wall, comprising the following steps:

[0039] S1, selecting a soil sample, mixing clay, gravel and lime, and adding water during the mixing process, the amount of water being 12-15% of the dry weight of the soil material;

[0040] S2, mold frame erection, using aluminum alloy templates and high-strength bolts to build a mold frame unit 1, and sealing the gap between the aluminum alloy templates with rubber strips;

[0041] S3, layered filling and tamping, introducing the formed soil into the mold frame unit 1, and loosely laying the thickness of 15±0.5 cmm, tamping the formed soil in the mold frame unit 1, after the formed soil in the mold frame unit 1 is completely tamped, moving along the city wall 2 direction to the next tamping section, and the bottom of the mold frame unit 1 is in contact with the shaft-shaped supporting part 3 placed on the surface of the city wall 2.

[0042] An auxiliary formwork for forming rammed earth city walls is used in the aforementioned method for forming rammed earth city walls. Formwork unit 1 is needed to assist in the ramming work of city wall 2. To facilitate the movement of formwork unit 1 by workers during the ramming process, this invention incorporates the following design: [In conjunction with the attached...] Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the formwork unit 1 includes an end plate 11, an aluminum formwork frame one 12 fixedly connected to both sides of the end plate 11, and an aluminum formwork frame two 13 connected to the aluminum formwork frame one 12 by bolts. During the ramming of the rammed earth wall, the end plate 11 is fixed to the aluminum formwork frame one 12 by high-strength bolts on both sides. Then, the aluminum formwork frame one 12 and the aluminum formwork frame two 13 are fixed by bolts. Then, the mixed soil is poured into the formwork unit 1 and compacted using ramming equipment. After the current stage of ramming is completed, the workers need to move the formwork unit 1 to the next ramming point. It should be noted that during the ramming process, in order to avoid soil adhesion... On the surface of the mold unit 1, a release agent (such as a release agent or release wax) is applied to the inner wall of the mold unit 1. During the movement, the workers first need to dismantle the mold. Before the transfer, a shaft-shaped support component 3 is placed on the wall 2 at the ramming point to support the mold unit 1. Then, the handle (not shown in the figure) on the mold unit 1 is used to transfer it to the next ramming point. The shaft-shaped support component 3 contacts and supports the bottom of the mold unit 1. Since the wall 2 is high and narrow, it is not convenient to transfer it. In addition, there is a certain risk when transferring the large-volume mold unit 1 at high altitude. Therefore, the present invention is designed as follows:

[0043] The steel plate frame 14 is fixedly installed on the aluminum mold frame two 13, wherein the aluminum mold frame one 12 is provided with a slot for limiting the sliding of the steel plate frame 14, and a plurality of balls are embedded on the steel plate frame 14, the balls are limited to slide in the slot, the bolts between the aluminum mold frame one 12 and the aluminum mold frame two 13 are disassembled, the aluminum mold frame one 12 or the aluminum mold frame two 13 is pulled to adjust the position on the city wall 2, and the positioning unit 4 is arranged at the bottom of the aluminum mold frame one 12 and the aluminum mold frame two 13, the positioning unit 4 is used for positioning the aluminum mold frame one 12 and the aluminum mold frame two 13 during tamping and moving, so that when the tamping is completed, the staff can first disassemble the bolts between the aluminum mold frame one 12 and the aluminum mold frame two 13, then pull the aluminum mold frame one 12 or the aluminum mold frame two 13, so that the aluminum mold frame one 12 or the aluminum mold frame two 13 moves to the newly placed shaft-shaped support part 3, and the aluminum mold frame one 12 or the aluminum mold frame two 13 after moving is supported under the action of the positioning unit 4, then the other aluminum mold frame one 12 or the aluminum mold frame two 13 is moved, and before the two are contacted (that is, the aluminum mold frame one 12 and the aluminum mold frame two 13), the remaining shaft-shaped support part 3 is placed on the city wall 2, and when the position moving is completed, the bolt is locked to smoothly complete the transfer of the mold frame unit 1.

[0044] The positioning unit 4 in the application can effectively position the mold frame unit 1 after moving, and ensure the stability of the mold frame unit 1 during tamping, and the specific design is as follows: the positioning unit 4 comprises a positioning plate frame 41, the positioning plate frame 41 is fixedly installed with an annular sleeve 42, wherein the positioning plate frame 41 and the annular sleeve 42 are fixed by bolt fixing, and are fixed on the aluminum mold frame one 12 or the aluminum mold frame two 13, wherein the annular sleeve 42 is provided with a steel sleeve 43, one end of the steel sleeve 43 is located inside the annular sleeve 42, and the other end of the steel sleeve 43 located outside the annular sleeve 42 is fixedly installed with a steel rod frame 44, the steel rod frame 44 contacts the shaft-shaped support part 3 placed on the surface of the city wall 2 during position adjustment; as shown in the accompanying drawings, during tamping, the steel rod frame 44 corresponding to the aluminum mold frame one 12 and the aluminum mold frame two 13 contacts the shaft-shaped support part 3, and the two steel rod frames 44 are located between the shaft-shaped support parts 3. Figure 2

[0045] ​The steel sleeve 43 is also fixedly installed with multiple telescopic parts 432. The multiple telescopic parts 432 are distributed in an annular shape at equal angles inside the steel sleeve 43. A connecting shaft 423 is fixedly installed on the inner wall of the annular sleeve 42, and a driving sleeve 424 is installed on the connecting shaft 423. The driving sleeve 424 is in contact with the inner wall of the connecting shaft 423. One end of the driving sleeve 424 is located outside the annular sleeve 42. Multiple telescopic parts 425 are fixedly installed on the inner wall of the driving sleeve 424. Both the telescopic parts 432 and the telescopic parts 425 include a fixed sleeve 5, a movable shaft 51 that is slidably connected to the inner wall of the fixed sleeve 5, and a mechanism for... A spring 52 connects the movable shaft 51 and the fixed sleeve 5. The ends of the movable shaft 51 are embedded with balls. The inner wall of the connecting shaft 423 is provided with multiple limiting grooves 6 corresponding to the telescopic part 425. The limiting groove 6 includes a straight groove 61, a straight groove 62 communicating with the straight groove 61, and an arc-shaped groove 63 for connecting the straight groove 61 and the straight groove 62. A spring body 64 is connected between the connecting shaft 423 and the inner wall of the driving sleeve 424. A guide plate frame 65 is fixedly installed at the intersection of the straight groove 61 and the straight groove 62. One side of the guide plate frame 65 is an inclined surface and the other side is a right angle surface.

[0046] Multiple circular plate frames 426 are sequentially installed on the outer wall of the drive sleeve 424 along the axial direction. Among them, three circular plate frames 426 are installed on the outer wall of the drive sleeve 424 corresponding to aluminum mold frame one 12, and two circular plate frames 426 are installed on the outer wall of the drive sleeve 424 corresponding to aluminum mold frame two 13. Each circular plate frame 426 is fixedly installed with an arc-shaped protrusion 427. One side of the arc-shaped protrusion 427 is an arc-shaped inclined surface, and the other side is a right angle surface. The arc-shaped protrusion 427 is used to control the rotation direction of the telescopic part one 432. Multiple iron shafts 431 are fixedly installed at one end of the steel sleeve 43 inside the annular sleeve 42. An annular panel 421 rotatably connected to the annular sleeve 42 is installed inside the annular sleeve 42, and a groove 422 is provided on the annular panel 421. The iron shafts 431 slide within the groove 422. A torsion spring 45 is connected between the annular panel 421 and the inner wall of the annular sleeve 42. A magnet 428 is embedded near both ends of each groove 422. The magnet 428 generates an attractive force on the iron shafts 431.

[0047] Specifically, in conjunction with the appendix Figure 1 and attached Figure 2 As shown, during the ramming of the city wall 2, the positioning unit 4 is located between two axial support components 3, that is, the steel frame 44 is located between the two axial support components 3 and is in contact with them, combined with the attached... Figure 2As shown, the arrow indicates the direction of compaction. For ease of description, this direction is the positive direction. During the compaction process, the formwork unit 1 will be subjected to the force of the compaction equipment. In order to prevent the formwork unit 1 from being displaced due to the force, the steel rod 44 contacts the shaft-shaped support component 3. The shaft-shaped support component 3 prevents the steel rod 44 from displacing.

[0048] Combined with appendix Figure 2 Appendix Figure 8 and attached Figure 10 As shown, if the steel rod frame 44 below the aluminum mold frame 12 is displaced in the positive direction, the steel rod frame 44 will be subjected to the force of the shaft support component 3 and rotate counterclockwise. At this time, the telescopic part 425 on the inner wall of the drive sleeve 424 is located in the straight groove 61, and the straight groove 61 will hinder the telescopic part 425 from rotating. As a result, the drive sleeve 424 and the circular plate frame 426 on it will be in a state where they cannot rotate.

[0049] Appendix Figure 8 and attached Figure 9 This is a schematic diagram showing the positions of the circular plate holder 426 and the arc-shaped protrusion 427 corresponding to the aluminum mold base 12. The three circular plate holders 426 are distinguished based on their proximity to the end of the connecting shaft 423 (the end fixed to the annular sleeve 42). The first circular plate holder 426 is the one closest to the connecting shaft 423, the third circular plate holder 426 is the one furthest from the end of the connecting shaft 423, and the one in between is the second circular plate holder. The arc-shaped protrusions 427 on the first and third circular plate frames 426 face the same direction, while the arc-shaped protrusions 427 on the second circular plate frame 426 face the opposite direction. That is, the arc-shaped inclined surface on one side of the arc-shaped protrusions 427 on the second circular plate frame 426 corresponds to the right-angle surface of the arc-shaped protrusions 427 on the first circular plate frame 426, and the right-angle surface corresponds to the arc-shaped inclined surface of the arc-shaped protrusions 427 on the first circular plate frame 426.

[0050] The orientations of the circular plate frame 426 and the arc-shaped protrusion 427 corresponding to the aluminum mold frame 2 13 are different. The first circular plate frame 426 and its arc-shaped protrusion 427 corresponding to the aluminum mold frame 2 13 have the same orientation as the arc-shaped protrusion 427 on the second circular plate frame 426 corresponding to the aluminum mold frame 1 12. The second circular plate frame 426 and its arc-shaped protrusion 427 corresponding to the aluminum mold frame 2 13 have the same orientation as the arc-shaped protrusion 427 on the first circular plate frame 426 corresponding to the aluminum mold frame 1 12. During the ramming process, the telescopic part 432 inside the steel sleeve 43 corresponding to the aluminum mold frame 1 12 and the aluminum mold frame 2 13 both contact the arc-shaped protrusion 427 on the first circular plate frame 426; combined with the attached... Figure 10As shown, if the aluminum mold frame 12 moves forward during ramming, the steel rod frame 44 will be in contact with the shaft-shaped support member 3 and rotate counterclockwise under the action of the force, and then the multiple telescopic parts 432 inside the steel sleeve 43 will be in contact with the right-angled surface of the arc-shaped protrusion 427 on the first circular plate frame 426. Since the telescopic part 2 425 on the inner wall of the driving sleeve 424 is located in the straight groove 1 61, the straight groove 1 61 will hinder the rotation of the telescopic part 2 425, and then the driving sleeve 424 and the circular plate frame 426 thereon will be unable to rotate, so that the steel sleeve 43 cannot drive the steel rod frame 44 to rotate at this time, and the aluminum mold frame 12 cannot move forward during ramming. Figure 11 As shown, if the aluminum mold frame 12 moves forward during ramming, the steel rod frame 44 will be in contact with the shaft-shaped support member 3 and rotate counterclockwise under the action of the force, and then the multiple telescopic parts 432 inside the steel sleeve 43 will be in contact with the right-angled surface of the arc-shaped protrusion 427 on the first circular plate frame 426. Since the telescopic part 2 425 on the inner wall of the driving sleeve 424 is located in the straight groove 1 61, the straight groove 1 61 will hinder the rotation of the telescopic part 2 425, and then the driving sleeve 424 and the circular plate frame 426 thereon will be unable to rotate, so that the steel sleeve 43 cannot drive the steel rod frame 44 to rotate at this time, and the aluminum mold frame 12 cannot move forward during ramming.

[0051] After ramming, the mold frame unit 1 needs to be moved forward at this time, so the staff can first remove the bolts between the aluminum mold frame 1 2 and the aluminum mold frame 2 13, and then pull the aluminum mold frame 1 2 to move it forward to the newly placed shaft-shaped support member 3. In this process, the staff needs to press the driving sleeve 424 corresponding to the aluminum mold frame 1 2, so that the telescopic part 2 425 inside the driving sleeve 424 moves along the trajectory of the straight groove 1 61 to the end of the straight groove 2 62. In this process, the telescopic part 2 425 will pass through the inclined surface of the guide plate frame 65, and when it moves into the straight groove 2 62, the telescopic part 2 425 will be in contact with the right-angled surface of the guide plate frame 65. During the pressing of the driving sleeve 424, the driving sleeve 424 will press the spring body 64, and the driving sleeve 424 drives the three circular plate frames 426 thereon to adjust the position, that is, the second circular plate frame 426 and the arc-shaped protrusion 427 thereon move to the corresponding position of the telescopic part 1 432. At this time, the steel rod frame 44 moves forward, that is, the steel rod frame 44 rotates counterclockwise under the action of the shaft-shaped support member 3. Since the telescopic part 1 432 and the arc-shaped protrusion 427 on the second circular plate frame 426 are in the relationship as shown in the figure at this time, the arc-shaped protrusion 427 on the second circular plate frame 426 will hinder the clockwise rotation of the steel rod frame 44, so that the steel sleeve 43 cannot drive the steel rod frame 44 to rotate at this time, and the aluminum mold frame 1 2 cannot move forward during ramming. Figure 11As shown, when the steel pole frame 44 is rotated counterclockwise under the action of the shaft-shaped support member 3, the telescopic part one 432 will move along the inclined surface of the arc-shaped protrusion 427, and the steel pole frame 44 can be rotated counterclockwise. During the rotation of the steel pole frame 44, the steel sleeve 43 will rotate synchronously, and the iron shaft body 431 on the steel sleeve 43 will drive the annular panel 421 to rotate through the sliding groove 422, and the torsion spring 45 is in the energy storage state. After passing through the shaft-shaped support member 3, the steel sleeve 43 will drive the steel pole frame 44 to rotate clockwise under the action of the torsion spring 45 in the energy storage state. Then, the telescopic part one 432 on the inner wall of the steel sleeve 43 will exert a force on the right-angle surface of the arc-shaped protrusion 427 on the second circular frame 426, so that the telescopic part two 425 on the inner wall of the driving sleeve 424 moves along the track of the straight groove body two 62 to the end in contact with the arc-shaped groove body 63. Then, under the action of the spring body 64, the telescopic part on the inner wall of the driving sleeve 424 moves along the track of the arc-shaped groove body 63, and finally enters the straight groove body one 61 and returns to the initial position. When the driving sleeve 424 returns to the initial position, the first circular frame 426 and the arc-shaped protrusion 427 thereon on the outer wall of the driving sleeve 424 will be in contact with the telescopic part one 432, thereby preventing the steel pole frame 44 from rotating counterclockwise. Move to the aluminum mold frame one 12 to make it contact with the newly inserted shaft-shaped support member 3.

[0052] When the aluminum mold frame two 13 moves forward, the first circular frame 426 and the arc-shaped protrusion 427 thereon corresponding to the aluminum mold frame two 13 are in the same direction as the arc-shaped protrusion 427 on the second circular frame 426 corresponding to the aluminum mold frame one 12. Therefore, when the aluminum mold frame two 13 moves forward, the steel pole frame 44 will contact the shaft-shaped support member 3 and be acted upon to rotate counterclockwise. At this time, the steel pole frame 44 passes through the shaft-shaped support member 3. At this time, the mold frame unit 1 has been transferred to a new ramming point, and the two steel pole frames 44 are located between the shaft-shaped support members 3.

[0053] When the same plane city wall 2 ramming is completed, if it is needed to ram up to increase the height of the city wall 2 at this time, then the corresponding number of workers or corresponding equipment will lift the formwork unit 1 to a certain height, and place the shaft-shaped support part 3 on the newly rammed city wall 2 surface to support the bottom of the formwork unit 1, when the formwork unit 1 is stable, the workers ram at this time to increase the height of the city wall 2; when the ramming is completed, the formwork unit 1 needs to be transferred to the next ramming point, at this time the movement of the formwork unit 1 is reversed, which is reverse movement, the specific reason is: if the formwork unit 1 starts ramming from point A on the same plane, and completes ramming at point B, then lifts up at point B and continues to ram, at this time the ramming starting point is point B and the ending point is point A, so it is reverse movement; further, when the ramming is completed, the workers need to adjust the position of the formwork unit 1 at this time, so that the end plate 11 faces the reverse movement, and then move the formwork unit 1; in this process, the steel sleeve 43 needs to be pulled outwards, so that the iron shaft body 431 on the steel sleeve 43 moves from one end of the sliding groove 422 to the other end, and the extension part one 432 on the inner wall of the steel sleeve 43 will contact the arc-shaped protrusion 427 on the second circular plate frame 426;

[0054] Further, when the aluminum formwork one 12 moves reversely, the steel rod frame 44 contacts the shaft-shaped support part 3 and is subjected to a force, at this time the steel rod frame 44 corresponding to the aluminum formwork one 12 will rotate clockwise, since the extension part one 432 on the inner wall of the steel sleeve 43 contacts the arc-shaped protrusion 427 on the second circular plate frame 426, further clockwise rotation will be hindered, when the driving sleeve 424 is pressed so that the arc-shaped protrusion 427 on the third circular plate frame 426 contacts the extension part one 432, at this time the steel rod frame 44 can rotate clockwise;

[0055] When the aluminum formwork two 13 moves reversely, it will also rotate clockwise in the moving process, but since the arc-shaped protrusion 427 on the second circular plate frame 426 corresponding to the aluminum formwork two 13 is opposite to the arc-shaped protrusion 427 on the second circular plate frame 426 corresponding to the aluminum formwork one 12, the steel rod frame 44 can rotate clockwise;

[0056] In the ramming process, two steel pole frames 44 are located between the shaft-shaped support components 3, so that the mold frame unit 1 is subjected to the ramming force in the ramming process. At this time, since the two steel pole frames 44 are located between the shaft-shaped support components 3, the aluminum mold frame 12 can only move in the reverse direction if it is displaced, and the steel pole frame 44 corresponding to the aluminum mold frame 12 will rotate clockwise. Since the telescopic part 432 on the inner wall of the steel sleeve 43 is in contact with the arc-shaped protrusion 427 on the second circular frame 426, the clockwise rotation will be hindered. The aluminum mold frame 13 can only move in the forward direction if it is displaced, since the arc-shaped protrusion 427 on the second circular frame 426 corresponding to the aluminum mold frame 13 is opposite to the arc-shaped protrusion 427 on the second circular frame 426 corresponding to the aluminum mold frame 12, and the steel pole frame 44 cannot rotate counterclockwise. Through the structural design of the present application, the mold frame unit 1 in the ramming process can be effectively limited to avoid displacement, and the mold frame unit 1 can also be easily transferred to a new ramming point.
