Description

Technical Field

[0001] The utility model relates to the technical field of raw earth buildings, in particular to a novel raw earth wall structure. Background Art

[0002] Raw earth wall is a kind of wall which uses unbaked soil, such as clay, sand, etc., or original soil that has been simply processed as the main material. Raw earth wall has various advantages such as local materials, green environmental protection, low cost, good thermal insulation effect, etc., and has been widely used in Chinese history. Although this type of building has been gradually eliminated with the development of the times due to factors such as low bending, shear and tensile strength of the wall, raw earth structure houses are still being built and used due to economic conditions and customs.

[0003] At present, the construction method of raw earth wall is on-site formwork installation. According to the design requirements of raw earth wall buildings, the formwork thickness is 500mm and wooden formwork is used for installation. Steel pipes are used for support and reinforcement in the horizontal, vertical and two sides. Through-wall screws are used with PVC sleeves, and mold release agent is applied after installation. The filler is compacted according to the normal compaction process. The thickness of each compacted layer is generally controlled at 300mm to 400mm. Such a construction process is not only troublesome to support the formwork, but also requires a large space for support on both sides of the formwork. Even if fibers such as wood, bamboo, and straw are added to the fill for compaction, the strength of the wall finally formed is still low and easy to crack, which leads to low integrity of the house. Under the action of an earthquake, the wall is very likely to tilt or collapse due to insufficient bearing capacity, further causing the floor or roof to fall, thereby destroying the entire house and causing casualties. Utility Model Content

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A new type of raw earth wall structure, comprising:

[0006] A pair of templates, wherein four through holes are opened inside the templates, a connecting rod is slidably connected inside the pair of through holes, a nut is threadedly connected to the end of the connecting rod, and three first baffles are connected to the outside of the connecting rod and located inside the pair of templates;

[0007] A pair of grooves are provided on the outer side of the connecting rod, a steel bar is slidably connected above the groove, and six second baffles are connected to the outer side of the steel bar.

[0008] In a possible implementation, a thread groove is formed at the end of the connecting rod, and the thread groove is threadedly connected to the nut.

[0009] In a possible implementation, a fixed stopper is connected to the outer side of the connecting rod near the thread groove.

[0010] In a possible implementation manner, the three first baffles are distributed at equal intervals, and a pair of the grooves are arranged at a middle position between two adjacent first baffles.

[0011] In a possible implementation manner, the six second baffles are distributed at equal intervals.

[0012] In a possible implementation, the connection between the steel bar and the connecting rod is tied with iron wire.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. Using nuts and connecting rods to fix the formwork on both sides can save a lot of space compared to the traditional formwork that uses wooden blocks or steel cages for support on both sides.

[0015] 2. The connecting rod can not only reduce the space of the supporting formwork to facilitate the construction process, but also further improve the bearing capacity of the rammed earth wall and reduce the degree of wall cracking.

[0016] 3. The length and width of the fixed formwork can be made suitable for the construction of rammed earth walls of any thickness by simply adjusting the length of the connecting rod, which is conducive to mass production.

[0017] 4. According to the thickness of the wall and the required bearing capacity, the number of the second baffle and the first baffle on the connecting rod can be flexibly changed to ensure that the connecting rod provides sufficient lateral restraint force. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The embodiments of the present application solve the problems in the prior art by providing a new type of raw earth wall structure.

[0027] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0028] Embodiment 1:

[0029] The specific structure of this embodiment is as follows: Figure 1-Figure 4 As shown, a new type of raw earth wall structure includes:

[0030] A pair of templates 6, with four through holes 7 formed inside the templates 6, a connecting rod 4 slidably connected inside the pair of through holes 7, a nut 5 threadedly connected to the end of the connecting rod 4, three first baffles 1 (this number can be adjusted according to actual conditions) connected to the outside of the connecting rod 4 and inside the pair of templates 6, the first baffle 1 is used in the rammed earth wall to share the lateral pressure caused by the longitudinal load of the soil, and is also used to restrict the lateral displacement of the soil. The groove 8 is used to fix the placed steel bars 2, and the second baffle 3 is provided on the steel bars 2 to increase the connection between the steel bars 2 and the fill, so as to increase the shear strength of the wall;

[0031] A pair of grooves 8 are provided on the outside of the connecting rod 4, and a steel bar 2 is slidably connected above the groove 8. Six second baffles 3 are connected to the outside of the steel bar 2 (this number can be adjusted according to actual conditions). After fixing the template 6, the steel bar 2 is placed on the groove 8 of the connecting rod 4. The second baffles 3 on the steel bar 2 increase the longitudinal bonding force between the steel bar 2 and the backfill. At the same time, the steel bar 2 and the connecting rod 4 are tied together with wire at the groove 8, and then the backfill material required for the rammed earth wall is added to the template 6. The backfill added first should be flush with the height of the template 6, and then compacted; after the first filler is compacted, continue to add filler for compaction. After multiple additions of filler and compaction, it is ensured that the filler fills the entire template 6 and the compaction degree meets the requirements.

[0032] In some examples, a threaded groove 10 is provided at the end of the connecting rod 4, and the threaded groove 10 is threadedly connected to the nut 5. Rotating the nut 5 is conducive to fixing the template 6 in the middle position between the fixed block 9 and the nut 5. Similarly, the nut 5 can be rotated in the opposite direction to loosen the nut 5 and take out the template 6 at the same time. At this time, the connecting rod 4 and the steel bar 2 are already inside the wall and holes are left on the wall. In order to make the wall smooth and beautiful, it is smoothed with soil at this time, and all the wall tamping processes in this section of the template 6 can be completed.

[0033] In some examples, a fixed stopper 9 is connected to the outer side of the connecting rod 4 near the thread groove 10. First, the length of the connecting rod 4 is determined according to the thickness of the wall. The length of the connecting rod 4 can be determined by the thickness of the rammed earth wall to be built. After the length of the connecting rod 4 is determined, the template 6 is installed. One template 6 has four through holes 7. The through holes 7 of the two templates 6 are correspondingly inserted into the connecting rod 4, and then the template 6 is fixed with a nut 5. At the same time, it is necessary to ensure that the fixed stopper 9 on the connecting rod 4 is close to the template 6 to prevent the template 6 from loosening and causing the template to expand when the soil is compacted.

[0034] In some examples, the three first baffles 1 are distributed at equal intervals, and a pair of grooves 8 are disposed in the middle of two adjacent first baffles 1 .

[0035] In some examples, the six second baffles 3 are distributed at equal intervals.

[0036] In some examples, the connection between the steel bar 2 and the connecting rod 4 is tied with iron wire. After the template 6 is fixed, the steel bar 2 is placed on the groove 8 of the connecting rod 4. The second baffle 3 on the steel bar 2 increases the longitudinal bonding force between the steel bar 2 and the fill. At the same time, the steel bar 2 and the connecting rod 4 are tied with iron wire in the groove 8.

[0037] By adopting the above technical solution:

[0038] Compared with the traditional formwork supported by wooden blocks or steel cages on both sides, the use of nuts 5 and connecting rods 4 to fix the formwork 6 on both sides can save a lot of space; the connecting rods 4 can not only reduce the space for supporting the formwork 6 to facilitate the construction process, but also further improve the bearing capacity of the rammed earth wall and reduce the degree of wall cracking; the length and width of the fixed formwork 6 can be made suitable for the construction of rammed earth walls of any thickness by only adjusting the length of the connecting rods 4, which is conducive to mass production; according to the thickness of the wall and the required bearing capacity, the number of the second baffle 3 and the first baffle 1 on the connecting rod 4 can be flexibly changed to ensure that the connecting rod 4 provides sufficient lateral restraint.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
