Description

Technical Field

[0001] The invention relates to building technology, in particular to a staggered lowering slab building structure. Background Art

[0002] For housing construction, the most common apartment types at present are flat-floor apartments and duplex apartments. The so-called flat-floor apartment refers to a building structure in which all functional areas of the house (living room, dining room, bedroom, etc.) are on the same plane; while the duplex apartment refers to a building structure in which the public area and private area are on two floors or more.

[0003] The floor height of a building refers to the height difference between the component beams of the next floor and the component beams of the previous floor. The building floor height type of a flat-type apartment is relatively simple, and all functional areas are distributed on the same horizontal plane; although the duplex type divides the functional areas between different floors, the total floor height of the entire house is equivalent to twice that of the flat-type apartment. Regardless of whether it is a flat-type apartment or a duplex type, the building area of ​​the house in actual use mostly only utilizes the spatial span of the house in the horizontal direction, and very few buildings can utilize the spatial span in the height direction. Therefore, most of the buildings currently have space waste in the height direction, resulting in a low space utilization rate of their building buildings. Summary of the invention

[0004] The purpose of the present invention is to provide a staggered and lowered floor building structure, which can utilize the space in the height direction of the building to improve the space utilization rate of the building.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a staggered and descending floor building structure, comprising a building main body, a building floor slab integrally cast in the building main body and layering the building main body along the height direction, and a building wall slab integrally cast in the building main body and partitioning the building main body along the horizontal direction. The building floor slab located in the functional area on the side of the building main body sinks downward to form a descending floor layer, and the descending floor layer between two adjacent floor slabs is respectively located on both sides of the building main body. A descending floor space is formed between the descending floor layer and the building floor slab located above it, and a layered board is arranged in the descending floor space to separate the descending floor space into functional areas distributed up and down.

[0006] By adopting the above solution, after lowering the floor of one of the functional areas and setting up layered boards, the functional area can have an extra layer of structure, and the extra layer of space can be used as a separate functional area. For small-sized buildings, such a building structure can effectively increase the usable area of ​​the house without changing the area of ​​the house, and such a design does not need to change the floor height of each floor of the building. It only needs to contribute part of the floor height of a certain area in the building as a new functional area. This can effectively solve the problem of shortage of land resources and insufficient per capita living area in large domestic cities, thereby effectively improving the space utilization rate of the house.

[0007] The present invention is further configured as follows: the settling height of the drop plate layer is 1 m to 1.2 m.

[0008] The floor height of commercial housing in my country is mostly 3m to 3.2m, and the average height of Chinese men is 1.67m. By adopting the above solution, after lowering the floor of some functional areas of the house by 1 to 1.2m, the floor height of this area can reach 4 to 4.4m. After being divided into two floors, the floor height of the single-story structure still has about 2m of usable height, which can meet the living requirements of most ordinary people in my country. Moreover, such a lowered height will not cause too much height difference between other functional areas and the functional areas after the lowering, thereby reducing the height span between functional areas while ensuring the normal activity height.

[0009] The present invention is further configured such that the distance between the layered plate and the upper building floor is smaller than the distance between the layered plate and the lower building floor.

[0010] By adopting the above scheme, people usually spend their daily activities in the lower structure, and the upper structure is generally used as a living room. Therefore, after setting the spatial height of the lower structure to be greater than that of the upper structure, the space where people spend a long time has a larger span, which can reduce the sense of crampedness caused by the lowering of the floor layer.

[0011] The present invention is further configured as follows: the layered plate includes a fixed plate and a sliding plate, the building wall panels connected to the layered plate include an upper wall panel and a lower wall panel, the lower wall panel and the fixed plate are both fixed to the building body, the sliding plate is integrally connected to the upper wall panel, a folding space is formed between the fixed plate and the lower wall panel for the sliding plate to enter and retract under the fixed plate, and a guide mechanism is provided on the building body to guide the movement of the sliding plate and the upper wall panel.

[0012] By adopting the above solution, when it is necessary to increase the space above the drop-down area, the upper wall can be pulled to the side away from the fixed plate, which can increase the area of ​​the space above the drop-down area, thereby achieving the purpose of freely expanding the usable space of the house.

[0013] The present invention is further configured as follows: the guide mechanism includes at least two rows of guide rail grooves opened on the inner wall of the building body and distributed up and down, and guide wheels rotatably installed on the sliding plate and the upper wall plate, and at least three groups of guide wheels are provided, and the three groups of guide wheels are respectively located at one end of the sliding plate away from the upper wall plate, one end of the upper wall plate away from the sliding plate, and one end of the sliding plate close to the upper wall plate, and the guide wheels are embedded in the guide rail grooves.

[0014] By adopting the above solution, the guide rail groove is used to guide the movement of the upper wall plate, and the guide wheel is used to reduce the resistance received by the upper wall plate and the sliding plate, thereby achieving the purpose of facilitating the movement of the upper wall plate and the sliding plate.

[0015] The present invention is further configured as follows: the guide wheel is rotatably mounted on the sliding plate through a bearing plate, the bearing plate is L-shaped, the bearing plate is inverted on the sliding plate and supported below the sliding plate.

[0016] By adopting the above solution, since the bearing plate is supported upside down under the sliding plate and the guide wheel is installed on the support plate, the support plate can support the rotating axis of the guide wheel, so that the rotating axis of the guide wheel is not easily deflected, thereby enabling the sliding plate and the upper wall plate to move better.

[0017] The present invention is further configured as follows: the sliding plate is provided with a locking mechanism for fixing the sliding plate to the building body, the locking mechanism includes an installation groove opened on the side wall of the sliding plate facing the guide rail groove, a locking column penetrated in the installation groove, and a locking groove opened on the inner wall of the guide rail groove, and the locking column is embedded in the locking groove under the drive of the driving mechanism.

[0018] By adopting the above scheme, when the upper wall panel and the sliding plate are pulled to the side away from the fixed plate, the installation groove and the locking groove are aligned, and the locking column can be embedded in the locking groove under the drive of the driving mechanism. At this time, the two ends of the locking column are respectively located in the building body and the sliding plate, and its length direction is perpendicular to the movement direction of the sliding plate, so the position of the sliding plate and the upper wall panel can be fixed.

[0019] The present invention is further configured as follows: the driving mechanism includes a driving groove opened on the sliding plate and connected to the mounting groove, a driving block hinged in the driving groove, an interference block fixed on one end of the locking column close to the driving block, and an elastic member sleeved on the locking column and located between the interference block and the inner wall of the driving groove; there are at least two adjacent planes on the driving block, one of which is called a locking state surface, and the other is called an unlocking state surface; the distance between the locking state surface and the hinge point of the driving block is greater than the distance between the unlocking state surface and the hinge center of the driving block, and the hinge center of the driving block is located on the extension line of the length axis of the locking column.

[0020] By adopting the above scheme, when the sliding plate and the upper wall plate need to be fixed, the driving block is rotated so that the contact surface between the driving block and the resistance block changes from an unlocked state surface to a locked state surface. During the rotation of the driving block, the locking column will be gradually pushed out of the installation groove so that the locking column is embedded in the locking groove, thereby achieving the purpose of fixing the upper wall plate and the sliding plate; when the sliding plate and the upper wall plate need to be moved, the contact surface between the driving block and the resistance block is returned from the locked state surface to the unlocked state surface. During this process, the locking column will retract into the installation groove until it is out of the locking groove, thereby allowing the sliding plate and the upper wall plate to move.

[0021] The present invention is further configured as follows: an inlet and an outlet are provided on the fixed plate, a ladder is installed on the inlet and an outlet, the ladder includes two side panels, foot pedals rotatably installed on the side panels and distributed along the length direction of the side panels, the side panels are provided with arc grooves equal in number to the foot pedals and arranged along the length direction of the side panels, the center of the arc grooves is located at the rotation center of the foot pedal, a guide column for embedding in the arc grooves is fixed on the side of the foot pedal, and a linkage mechanism for driving the foot pedal to flip is provided on the side panels.

[0022] By adopting the above scheme, the foot pedals of the ladder are arranged to be flippable, and when going upstairs, they are flipped over to form a staircase shape for workers to go upstairs, and when going downstairs, the foot pedals can be connected end to end to form a slide, so that the stairs can have the functions of both a slide and stairs, thereby expanding the entertainment function of the stairs.

[0023] The present invention is further configured as follows: the linkage mechanism includes a linkage rod which is arranged on one side of the ladder and forms a rotational connection with all guide columns located on the same side of the ladder, and a toggle rod rotatably installed on the rotating shaft of the foot pedal, the middle part of the toggle rod is hinged to the linkage rod, and when the toggle rod is flipped to be parallel to the length direction of the side panel, all the foot pedals are connected end to end to form a slide.

[0024] By adopting the above scheme, when the toggle rod is rotated to the side parallel to the side panel, the foot pedal flips up and gradually fits together to form a slide. Since the rotation axes of the guide column and the foot pedal are located on the same straight line at this time, the gravity of a person pressing on the foot pedal will generate two components of force, one perpendicular to the foot pedal and the other parallel to the foot pedal. Neither of these two forces will cause the foot pedal to flip over. Therefore, this can not only achieve the linkage of the foot pedal adjustment and flipping, but also ensure the stability of the foot pedal when it becomes a slide.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. The structure of staggered floor slabs can expand the usable area of ​​the building without changing the building height and building area, effectively utilize the space in the building height direction, and greatly improve the space utilization rate of the building;

[0027] 2. The pullable sliding plate and upper wall plate can adjust the size of the expanded space, so that the expanded space can be freely transformed, thereby further improving the space utilization rate;

[0028] 3. The dual-purpose form of stairs and slides can increase the function of the ladder, so that the ladder has both climbing and entertainment functions. BRIEF DESCRIPTION OF THE DRAWINGS
