Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a foundation structural system suitable for a lying box-type house. Background Art

[0002] Container houses have been widely used in temporary construction projects on construction sites. They are widely used in the construction field and emergency scenarios for their fast construction speed, low turnover cost, and convenient and comfortable use. Unlike traditional concrete houses, the foundation form and material selection of container houses are relatively flexible. The foundation only needs to meet the bearing capacity of the container houses stacked on it and ensure that it will not break due to uneven settlement of the site. At present, strip concrete foundation is the first choice in general projects. Its formwork and pouring are simple, and the amount of concrete used is small, which saves costs and meets the requirements of use.

[0003] However, in some special cases, strip concrete foundations are not fully applicable. When the box-type house lies below the outdoor floor, it not only needs to meet the bearing capacity requirements, but also needs to solve the hidden dangers of waterproofing caused by lying under the outdoor floor. Therefore, there is an urgent need for a sunken box-type house foundation structure system that can effectively solve the problem of water storage under the foundation and prevent the service life of the box-type house from being affected by long-term immersion in water.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figure 1-Figure 2The utility model discloses a foundation structure system suitable for a lying box-type house, comprising a foundation pit opened outdoors, a fine stone cushion layer 1 being paved at the bottom of the foundation pit, and gray sand silicon retaining walls 2 being respectively arranged on the side walls of the foundation pit, the gray sand silicon retaining walls 2 being arranged on the fine stone cushion layer 1, a concrete layer 4 being arranged on the fine stone cushion layer 1, the top surface of the concrete layer 4 being used for placing a box-type house 7, a flashing edge sealing 5 being arranged on the top surface of the gray sand silicon retaining wall 2, and the flashing edge sealing 5 being in contact with the outer wall of the box-type house 7; a waterproof treatment layer 3 is respectively paved on the top surface and side wall of the gray sand silicon retaining wall 2 and the top surface of the fine stone cushion layer 1.

[0021] The waterproof treatment layer 3 is made of waterproof material and is laid on the fine stone cushion layer 1 and the inner side of the gray sand silicon retaining wall 2 to prevent underground water from returning.

[0022] The utility model arranges a fine stone cushion layer 1, a gray sand silicon retaining wall 2, a waterproof treatment layer 3, and a concrete layer 4 in the foundation pit, which can not only provide a stable foundation for the sinking of the box-type house 7, but also effectively solve the problem of water storage in the lower part of the foundation through the flashing edge sealing 5, thereby preventing the service life of the box-type house 7 from being affected by long-term immersion in water.

[0023] According to the further optimization scheme, the thickness of the fine stone cushion layer 1 is 50 mm to 100 mm. The fine stone cushion layer 1 is laid at the bottom of the foundation pit to level and protect the waterproof treatment layer 3.

[0024] According to a further optimized solution, the top surface of the gray-sand silicon retaining wall 2 extends out of the top surface of the foundation pit.

[0025] The lime sand silicon retaining wall 2 is built on the side of the sinking foundation pit, with a width of 240mm. The lower elevation of the lime sand silicon retaining wall 2 is the upper surface of the fine stone cushion layer 1, and the upper elevation of the lime sand silicon retaining wall 2 is 50mm higher than the outdoor floor to resist the sand on the side of the foundation pit.

[0026] According to a further optimized solution, a plurality of reinforcing bars 6 are arranged in the concrete layer 4 .

[0027] To further optimize the solution, several reinforcement bars 6 are arranged crosswise up and down.

[0028] Concrete layer 4 is a bearing structure that meets the bearing capacity requirements of container houses 7; concrete layer 4 is cast with 200mm thick C25 concrete, and reinforcement 6 is cross-arranged φ14mm ribbed steel bars with a spacing of 150mm.

[0029] According to a further optimization scheme, a slope is provided on the portion of the flashing edge seal 5 on the top surface of the gray sand silicon retaining wall 2 .

[0030] The flashing edge seal 5 is a bent component of a color steel plate, which is used to prevent rainwater from entering the foundation pit; the flashing edge seal 5 is arranged at the connection position between the lime-sand silicon retaining wall 2 and the box-type house 7. When the flashing edge seal 5 is installed, it is necessary to apply glue and waterproof treatment between the box-type house 7 and the flashing edge seal 5; the part of the flashing edge seal 5 on the outer wall of the lime-sand silicon retaining wall 2 extends between the foundation pit slope and the lime-sand silicon retaining wall 2 to prevent the ground water from soaking the lime-sand silicon retaining wall 2.

[0031] To further optimize the solution, a drainage ditch is set outside the foundation pit, so that rainwater on the flashing seal 5 can flow into the drainage ditch along the slope; the drainage ditch can promote the organized collection of surrounding rainwater and reduce the intrusion of rainwater into the lower horizontal foundation.

[0032] Working process: excavate the foundation pit according to the designed depth, lay a 50mm thick fine stone cushion layer 1 at the bottom of the foundation pit; build a 240mm thick gray sand silicon retaining wall 2 on the side of the foundation pit; make a waterproof treatment layer 3 on the fine stone cushion layer 1 and the inner side of the gray sand silicon retaining wall 2; cross-arrange several reinforcements 6 on the waterproof treatment layer 3, with a spacing of 150mm between adjacent reinforcements 6, and cast a 200mm thick concrete foundation; after the concrete reaches the required strength, hoist the box-type house 7 into place, and then install the flashing edge sealing 5.
