Description

Technical Field

[0001] The present invention relates to the technical field of rammed earth construction, and particularly to an earthquake-resistant rammed earth wall structure. Background Art

[0002] The main characteristics of rammed earth walls include environmental protection, heat insulation, earthquake resistance, wind resistance, and aesthetic appearance. The main material used in rammed earth walls is natural soil, which is non-toxic and harmless and does not pollute the environment. Moreover, during the construction process, there is no need to cut or damage materials such as stones and bricks, thus avoiding damage to the ecological environment. Its high-density structure and the heat absorption performance of the soil enable the rammed earth wall to effectively prevent heat from entering in summer and maintain the indoor temperature in winter. Therefore, it is widely used in energy-saving buildings. The dense structure and integrated wall structure of the rammed earth wall endow it with stable earthquake and wind resistance capabilities in natural disasters such as earthquakes and strong winds and heavy rains. In addition, the natural texture and rich colors of the rammed earth wall have excellent aesthetic effects and are suitable for civil residences, commercial buildings and other fields.

[0003] Among the prior arts, Patent Application No. 201611027804.6 provides an embedded wattle-reinforced foam block rammed earth wall and its construction process, including a rammed earth wall, foam blocks, transverse wattles, and longitudinal wattles. The foam blocks are cuboid structures, and the longitudinal wattles pass through the foam blocks. The longitudinal wattles and the foam blocks form a foam reinforcement unit. The foam reinforcement units are arranged in the rammed earth wall and are distributed in a square array along the length and height directions of the rammed earth wall. The longitudinal wattles of the foam reinforcement units distributed along the length direction of the rammed earth wall are connected by transverse wattles. In the present invention, multiple foam reinforcement units are arranged between the layers of the rammed earth wall, and the foam reinforcement units are connected by transverse wattles, which can effectively reduce the self-weight of the rammed earth wall, and at the same time can effectively prevent the adhesion force between the layers of the rammed earth wall and prevent the extension of cracks between the layers, thereby achieving the purpose of improving the earthquake resistance of rammed earth buildings.

[0004] However, in the prior art, although the rammed earth wall has the effects of energy conservation and environmental protection, its earthquake resistance performance is not high enough, there are certain potential safety hazards. In particular, the outer facade of the wall lacks protection design, and it is prone to weathering or damage by insects and rodents during long-term use.

[0005] Therefore, it is necessary to design an earthquake-resistant rammed earth wall structure to optimize the disadvantages of conventional technologies. Summary of the Invention

[0006] The purpose of the present invention is to provide an earthquake-resistant rammed earth wall structure to solve the problems of limited earthquake resistance performance of conventional rammed earth wall structures and easy occurrence of weathering or damage by insects and rodents.

[0007] To solve the above technical problems, the present invention adopts the following technical solutions:

[0008] The present invention provides a seismic rammed earth wall structure, which includes a seismic isolation base, a plurality of columns arranged on the seismic isolation base, a support beam arranged on the tops of the columns, a rammed earth layer arranged between the seismic isolation base and the support beam, and a protection plate arranged outside the rammed earth layer.

[0009] Further, the seismic isolation base includes horizontally arranged steel bars and concrete casting materials; vertical steel bars are arranged in the columns.

[0010] Still further, a plurality of embedded pipes Ⅰ are evenly spaced in the rammed earth layer; a plurality of embedded pipes Ⅱ are horizontally embedded in the columns.

[0011] Still further, a limiting ring or a special-shaped limiting member for increasing the contact area is arranged on the embedded pipe Ⅰ.

[0012] Still further, the protection plate includes a support net arranged on both sides of the rammed earth layer through fasteners, and a concrete layer cast outside the support net.

[0013] Still further, the fasteners include a pull rod adapted to be inserted into the embedded pipe Ⅰ or the embedded pipe Ⅱ, fixing disks arranged at both ends of the pull rod, and a rotating disk sleeved on the pull rod and used for clamping the support net;

[0014] A plurality of "L"-shaped locking hooks are arranged on the end faces of the fixing disks, and a plurality of arc-shaped grooves adapted to the locking hooks are evenly formed on the rotating disk.

[0015] Still further, its construction steps are as follows:

[0016] S1. First, design the seismic isolation base. According to the building height and load-bearing requirements, design the required thickness and width of the seismic isolation base; then, form the required columns on the seismic isolation base by steel bars and concrete casting; when casting the columns, embed the embedded pipes Ⅱ at even intervals.

[0017] S2. After the concrete in step S1 is cured and formed, construct the rammed earth layer on the seismic isolation base and around the columns. During the construction process, as the height of the rammed earth layer increases, gradually embed the embedded pipes Ⅰ with different heights, and load pull rods into the embedded pipes Ⅰ. The thickness of the rammed earth layer is less than the width of the seismic isolation base.

[0018] S3. After the height of the rammed earth layer reaches the design requirements, pour the support beam between adjacent columns.

[0019] S4. Next, a plurality of steel bar joints are vertically preset on both sides of the rammed earth layer on the shockproof base. After fixing the formed support net to the steel bar joints, at the same time, the "L" - shaped locking hooks on the fixing plate at the end of the pull rod extend outside the support net, and then the rotating disc outside the support net is used to rotate and lock through the arc - shaped groove on it, so as to use the pull rod to connect the support nets on both sides of the rammed earth layer; finally, based on the support net, a protective plate is cast and formed.

[0020] Compared with the prior art, the beneficial technical effects of the present invention are as follows: In the present invention, by means of the shockproof base, columns and support beams as the seismic support structure of the building wall, and at the same time, the rammed earth layer is used to ensure that the rammed earth wall has the functions of keeping warm in winter and cool in summer, and energy - saving and environmental protection. In this embodiment, a protective plate is also built outside the rammed earth wall, so as to prevent the rammed earth wall from being weathered or damaged by insects and rodents. The technical solution of this application can have both seismic performance and the energy - saving and environmental protection effects of the rammed earth wall. BRIEF DESCRIPTION OF THE DRAWINGS
