Description

Technical Field

[0001] This utility model relates to an arched house with an integrally formed steel foundation and steel superstructure. Background Technology

[0002] Existing steel-structured houses have wall structures and roof structures. The wall structure uses a rectangular steel frame with vertical walls perpendicular to the horizontal plane. The roof can be gabled, arched, or flat. For example, Chinese patent document CN213477340U discloses a roof structure for an integrated house. A wall is fixedly installed on the upper surface of the base. A door and window are fixedly installed on the front of the wall. A top plate is fixedly installed on the upper surface of the wall. The roof is fixedly installed on the upper surface of the top plate. A fixing plate is fixedly installed on the inner wall of the roof. Fixing blocks are fixedly installed on the upper and lower ends of the fixing plate. A fixing column is fixedly installed on the outer end of the fixing block. Reinforcing members are fixedly installed on the side wall of the fixing column. Chinese patent document CN118774312A discloses a steel roof structure, including a supporting frame and corrugated steel sheets; the corrugated steel sheets are laid on top of the supporting frame; the supporting frame includes several parallel A-beams, each A-beam having a mounting base connected to both ends, and each mounting base having a limiting groove at its bottom. The mounting bases at both ends of the A-beams are respectively engaged with the supporting beams on both sides of the top of the building body through the limiting grooves, and the mounting bases are connected to the supporting beams via connecting components. Chinese patent document CN119221606A discloses a modular prefabricated steel structure house, including a base frame module, side frame modules, a top frame module, and a roof module. The base frame module is divided into smaller base plates, and the lower positioning columns of the side frame modules pass through the movable engagement points of the base frame modules, limiting the movement of the base frame modules around their perimeter. The top frame module cooperates with the base frame module to position the upper and lower positioning columns of the side frames, forming the house frame structure. The functional frames cooperate with the upper positioning columns and are bolted together. These existing technologies each have their own characteristics and are suitable for various adaptive situations. However, certain limitations still exist. For example, rectangular frames and facade walls have relatively weak lateral force resistance, especially wind resistance, and are prone to stress concentration and torsion under horizontal loads, affecting the stability and safety of the building. In addition, the structure is relatively complex, the amount of steel used is large, and the construction process is complicated. Utility Model Content

[0003] The purpose of this invention is to simplify the structure and facilitate construction.

[0004] The technical solution of this utility model is: an arched house with an integrated steel foundation and upper structure, which together with the house floor encloses an arched interior space. The arched structure is assembled from several arched components, which are steel components, and their lower ends are fixedly installed on the foundation installation parts.

[0005] Arched components can be formed from suitable steel plates using pressure forming methods.

[0006] Preferably, the foundation mounting component is groove-shaped and is fixedly installed on the foundation or underground foundation structure. The foundation connection parts at both ends of the arched component are inserted into the grooves of the corresponding side foundation mounting components and fixed together with the foundation mounting components.

[0007] Preferably, the main body of the arched component is semi-circular, hyperbolic, or inverted catenary, the foundation connection is vertical, and the main body and foundation connection are smoothly transitioned.

[0008] Preferably, the arched component has folded edges on both sides.

[0009] Furthermore, one side of the arched component has a flange insertion groove, while the other side is flat and does not have a flange insertion groove.

[0010] Furthermore, in the two adjacent folds of adjacent arched components, the flat fold is inserted into the adjacent fold insertion groove, thereby realizing the connection between adjacent arched components.

[0011] Furthermore, vertical end walls are respectively provided at both ends of the arched structure to form the front wall and the rear wall.

[0012] Preferably, the front wall has a door, and may or may not have a window.

[0013] Preferably, the rear wall has a window, and may or may not have a door.

[0014] Furthermore, the arch structure can be a single structure or multiple structures connected sequentially from left to right. When there is only one arch structure, it has vertical outer walls on both sides and an outer roof on top, which is connected to the outer walls on both sides. When there are multiple arch structures, the arch structure group formed by the interconnection of multiple arch structures has vertical outer walls on both sides and an outer roof on top, which is connected to the outer walls on both sides.

[0015] Furthermore, the interior spaces of each arched structure are not interconnected; or, enclosed corridors connecting the interior spaces are set between some adjacent arched structures; or, enclosed corridors connecting the interior spaces are set between all adjacent arched structures.

[0016] Furthermore, a ground structure is set on the foundation, with the surface of the ground structure serving as the floor of the house. The arched structure and the ground structure together enclose the interior space.

[0017] The beneficial effects of this utility model are as follows: Because it uses integrally molded arched components (usually steel components) to assemble an arched structure, it achieves a seamless transition between the wall and the roof. This reduces the types and number of components used in assembling the house, simplifies the construction, and facilitates construction. Furthermore, the arched structure promotes balanced stress distribution, avoids or significantly reduces stress concentration, and improves the house's wind / lateral force resistance and other load-bearing capacity, thus enhancing its stability. The use of interlocking flat and slotted surfaces on the two sides of the arched components facilitates assembly and significantly improves the rigidity and load-bearing capacity of the arched components. The use of a large arched component span (e.g., 6 meters) not only creates a suitable indoor area but also minimizes the spacing (area) outside the 2.1-meter height dividing line. This allows for more effective utilization of the area outside the 2.1-meter height dividing line through a reasonable interior layout, effectively avoiding the waste of space caused by the arched design.

Detailed Implementation

[0027] See Figures 1 to 8 The structure of this house (the load-bearing structure) adopts an arched structure (the cross-section of which is an arch) 30, which integrates the foundation and the superstructure. The arched structure is assembled (sequentially spliced) by several arched components 10, and its lower ends on both sides are fixedly installed on the foundation installation components (the foundation installation components of the arched structure) to enclose the arched interior space.

[0028] The foundation installation components can be any connectors capable of fixing the two ends of the arched member. For example, bolts or steel plates (horizontal steel plates) can be pre-embedded in the concrete foundation beam, and the foundation connection on the arched member can be adapted to connect with the pre-embedded bolts or steel plates. The connection method between the foundation installation components and the arched structure depends on the specific form of the foundation installation components and should be able to achieve or not hinder the transfer of loads from the arched structure. This can be bolt fastening, welding, anchoring, etc.

[0029] In a preferred embodiment, the foundation mounting component is groove-shaped, forming a foundation mounting groove 22, which is fixedly mounted on the foundation 29 or foundation structure. The foundation connection portions 12 at both ends of the arched component (corresponding to the left and right sides of the arched structure) are inserted into the corresponding foundation mounting grooves and fixed together. For example, concrete 23 can be poured into the grooves to secure the foundation connection portions of the arched component to the foundation mounting component. When multiple arched structures are connected left and right, adjacent foundation connection portions of adjacent arched structures can be inserted into the same foundation mounting groove and fixed together by pouring concrete. If necessary, for the foundation mounting groove located on the outer side (either side), the lower end of the corresponding outer wall or the lower end of the frame / base used to install the outer wall can be inserted and anchored into the foundation mounting groove to facilitate the installation and fixing of the outer wall (the wall located on the side outside the arched structure).

[0030] When a concrete (including reinforced concrete) structure is set on the foundation, a foundation mounting groove or other form of foundation mounting component can be pre-embedded in the concrete structure. The top of the foundation mounting groove is aligned with or substantially aligned with the surface of the concrete structure (slightly higher or slightly lower) or higher than the surface of the concrete structure, with the groove opening facing upwards, so as to insert the foundation connection part of the arched component.

[0031] If necessary, a concrete foundation beam can be set on the foundation for embedding foundation installation components (e.g., foundation mounting slots) to secure / anchor the foundation mounting slots or other forms of foundation installation components to the concrete foundation beam.

[0032] Arched components are usually made of steel and can be called arched steel components or steel arch components. They can be formed by pressure forming of steel plates of suitable material.

[0033] The arched component includes a main body 11 and foundation connections at both ends of the main body. The shape of the main body (the end face / section shape of the main body) is semi-circular, hyperbolic, or inverted catenary. The shape of the foundation connections (the end face / section shape of the foundation connections) is vertical (an upright planar shape). The main body and foundation connections transition smoothly without sharp edges, and angular bends or bends with large curvatures are avoided as much as possible to prevent stress concentration.

[0034] Arched components can typically be constructed with bilateral symmetry.

[0035] The two edges of the arched component can be bent inward (inner side of the arch) at a 90° angle to form a folded edge (90° folded edge) 13. One folded edge is planar (or flat) and the other folded edge has a folded edge insertion groove 14. This not only improves the strength / load capacity of the arched component, but also allows the flat folded edge of the arched component to be inserted into the folded edge insertion groove of the adjacent arched component (if any) when assembling the arched component into an arched structure, thereby achieving fixation and sealing between adjacent arched components.

[0036] The folded edge and folded edge insertion groove can be formed by pressure forming. During preparation, the total width of the folded edge with the folded edge insertion groove should be reasonably set so as to form a folded edge insertion groove that is suitable for inserting flat plate-shaped folded edges. The specific forming steps or process methods can be based on existing technology.

[0037] At each end of the arched structure are vertical end walls (walls located at one end of the arch), forming the front wall and rear wall respectively. Both the front and rear walls are non-load-bearing exterior walls, installed at their respective ends of the arched structure. The end walls can be constructed from any suitable material and installed in any suitable manner. For example, frames (steel frames or frames of other suitable materials) can be installed at the front and rear ends of the arched structure to mount the end walls, with suitable materials (as well as door and / or window frames, if present) mounted on the corresponding frames for mounting the wall panels.

[0038] Doors and windows can be installed on the front and rear walls. For example, the front wall may or may not have a door 32; the rear wall may or may not have a window.

[0039] The arched structures that make up the same building can be one or multiple arched structures connected sequentially in the left-right direction. The interior spaces of adjacent arched structures may not be connected (each forming a unit); or, enclosed passages (e.g., corridors) may be set between some or all of the adjacent arched structures to connect multiple interior spaces (the interior spaces enclosed by multiple arched structures) to form a larger unit.

[0040] An arched structure group (multiple interconnected arched structures; when there is only one arched structure, the arched structure can be considered as an arched structure group) has a vertical outer wall 35 on its lateral outer side, and an outer roof 37 on its top. The outer roof connects to the two outer walls on both sides, forming an appearance similar to that of an existing ordinary house.

[0041] The installation of the exterior walls and roof can be achieved by using an arched structure or an arched structure and foundation / base setting for the installation of the exterior walls and roof.

[0042] The front and rear walls are connected to the outer walls (or their mounting frames) and the outer roof (or their mounting frames) on both sides and at the top, respectively, together forming the building's external structure (or exterior structure).

[0043] When multiple arched structures are provided, adjacent end walls (front or rear walls) located in the same axial position are connected to form the same wall surface.

[0044] When different arched structures are misaligned in the axial direction (the front or rear ends are not aligned), the side of the middle arched structure (excluding the arched structures on both sides) is not connected to other arched structures. The outer side of these sides can be regarded as the lateral outer side of the arched structure group, and corresponding outer walls are set.

[0045] The outer walls, roof, and front and rear walls together form the external structure of the building. The overall layout of the building's exterior structure can be based on the building's exterior design. For example, the front and rear walls can be directly used as the exterior structure. In this case, the size and shape of the front and rear walls not only need to meet the requirements of dividing the internal and external spaces of the arched structure, but also need to satisfy the requirements of the exterior structure, and be able to cooperate and connect with the outer walls and roof.

[0046] The desired exterior wall paint or other decorations can be applied to the surface of the exterior walls (outer walls, front walls, and rear walls) to achieve the desired aesthetic effect.

[0047] Because the external structure bears loads (e.g., wind loads), steel frames can be installed for the exterior walls and roof. These steel frames can be truss structures (support systems with diagonal bracing) supported (connected) to an arched structure. The connection points on the arched structure are preferably located at folded edges to improve the support capacity of the connection points. The truss structure can be configured according to actual needs. Since this truss configuration is not hindered by interior space, the position, direction, and density of the support rods can be set as needed, thus achieving sufficient load-bearing capacity and avoiding excessive torsion or localized stress concentration. The exterior walls and roof are installed on their respective frames.

[0048] When there are no outer walls and an outer roof, the shape of the end wall should generally conform to the end face of the arched structure so as to enclose the interior space together with the arched structure. When there are outer walls and an outer roof, the shape of the end wall should generally conform to the end face enclosed by the outer walls and the outer roof, forming the building's exterior shape together with the outer walls and the outer roof. A seal between the end wall and the arched structure (regardless of whether there are outer walls and an outer roof) can be achieved using existing technology or other suitable technologies.

[0049] A ground structure (a structure whose surface can be used as the interior floor) can be constructed on a foundation or base.26 For example, a layer of concrete to form a raft foundation can be poured between the foundation mounting slots on both sides before the arch structure is installed, or floor tiles or flooring can be dry-laid during finishing. The surface of the ground structure constitutes the floor of the house, and the arch structure and the ground structure together enclose the interior space.

[0050] For example, a concrete / reinforced concrete layer can be poured on a compacted foundation, or precast concrete slabs can be laid. If necessary, flooring or other floor finishing materials can be installed on the surface of the concrete / reinforced concrete layer or precast concrete slabs to form the desired floor. Alternatively, precast floor components can be installed and laid on the compacted foundation to form the desired house floor.

[0051] When setting up the ground structure, the indoor floor can be raised slightly so that its height is higher than the outdoor floor level. When setting up the foundation mounting groove, the top surface of the groove can be higher than the outdoor floor level, matching the indoor floor level, or the top of the groove can be higher than the indoor floor level (see [reference]). Figure 7 Example). Thus, the base mounting groove can be used as the corresponding side frame / boundary for raising / setting the floor structure of the indoor floor.

[0052] The construction method of this type of house mainly involves installing arched components sequentially (either from front to back or from back to front). When installing a later (meaning the arched component is installed last) arched component, the side of the later arched component adjacent to the side of the already installed arched component (or the preceding arched component) is connected to the side of the adjacent already installed arched component. The specific connection method depends on the specific structure of the side of the arched component. For example, when one side of an arched component has a flat flange and the other has a flange insertion groove, the flat flange is inserted into the corresponding flange insertion groove. If necessary, an elastic strip or sealant can be placed between the flat flange and the groove wall to achieve fixation and sealing between the flat flange and the flange insertion groove.

[0053] After setting up the arched structure, the front and rear walls, doors and windows and other facilities are set up according to the house design using appropriate existing technology. If necessary, the outer walls and roof on both sides of the arched structure (or arched structure group) are set up to form the required external structure (or appearance structure).

[0054] Before assembling the arch structure, foundation mounting components (e.g., trough-shaped foundation mounting components, or foundation mounting grooves) are fixedly installed on the foundation or base for installing the arch structure. For example, a trench for setting the foundation mounting groove is dug in the prepared foundation, and the foundation mounting groove is fixedly buried in the corresponding trench. If necessary, concrete can be poured in the trench (within the gap between the foundation mounting component and the trench) to form an underground beam structure for fixing and supporting the foundation mounting groove. The dimensions of the underground beam structure / the dimensions of the trench are set according to actual needs.

[0055] When appropriate, the foundation installation trenches can be directly buried in the foundation. If necessary, tie bars (or other forms of tie components, hereinafter the same) can be installed between adjacent foundation installation trenches. The tie bars are installed underground, and there can be multiple tie bars evenly distributed. For example, two tie bars can be installed between two foundation installation trenches, one at the front end and one at the back end, to tie the front and back ends of the foundation installation trenches.

[0056] Before installing the arched component, temporary connectors 16 are installed on the arched component. The temporary connectors can be made of suitable materials such as steel bars, wire ropes, or strip steel plates, and their two ends are respectively connected to the lower ends of the main body of the arched component (for example, the part of the main body of the arched component near the foundation connection) to facilitate the stability of the shape of the arched component.

[0057] The connection positions of temporary connectors on arched components can be rationally set so that after both ends of the arched component (foundation connection parts) are inserted into their respective foundation connection grooves, the temporary connectors precisely contact (press) the top of the foundation connection grooves. Therefore, during the assembly of arched components, the alignment of the temporary connectors with the top of the foundation connection grooves can be used as a criterion for determining proper insertion, facilitating construction. After installation, the temporary connectors are removed.

[0058] Unless otherwise specified, the preferred and optional technical means disclosed in this utility model can be arbitrarily combined to form several different specific embodiments when one preferred or optional technical means is a further limitation of another technical means.
