Description

Technical Field

[0001] This utility model relates to the field of grain storage building structures, and in particular to an arched wall structure for a flat warehouse. Background Technology

[0002] Traditional grain storage buildings typically use flat wall panels of uniform thickness for their side walls. When subjected to the horizontal pressure generated by the stacked materials inside the storage silo, tensile stress easily develops on the outer side of the wall panels. Because concrete is resistant to compression but not tension, traditional wall panels often require a large amount of steel reinforcement to compensate for the insufficient tensile strength, and are prone to cracking, which in turn affects the building's airtightness, waterproofing, and moisture-proofing performance. Furthermore, flat wall panels exhibit significant deflection under heavy loads, resulting in low material utilization efficiency. Utility Model Content

[0003] To address the problems of traditional flat wall panels being prone to tensile stress cracks, requiring large amounts of reinforcement, having poor airtightness, and having low material utilization when subjected to large loads, this utility model provides an arched load-bearing wall structure.

[0004] The solution adopted by this utility model to solve its technical problem is: a flat warehouse arched wall structure, including wedge-shaped columns and arched wall panels. The wedge-shaped columns are provided with mounting brackets on both sides, and the mounting brackets are set facing the inside of the warehouse. The arched wall panels are vertically installed between two adjacent wedge-shaped columns. The side of the arched wall panel facing the inside of the warehouse is flat and used to directly bear the load, while the side facing the outside of the warehouse is arched. Supports are provided at both ends of the arched wall panels. The thickness of the supports is greater than the thickness of the arched wall panel at the mid-span position, and the supports are engaged with the mounting brackets.

[0005] Preferably, the support has a cavity structure inside to reduce its own weight, and the cavity structure is filled with foam strips or has hollow holes.

[0006] Preferably, the cavity structure is arranged in at least one of the following ways: Within the support area, it is vertically extended along the height direction of the arched wall panel; The cavity structures are arranged at equal intervals along the width direction of the arched wall panel; The cavity structure has a cross-section that is circular, rectangular, or oblong.

[0007] Preferably, the arched wall panel is a spliced ​​structure that is broken in the middle, and the middle section of the spliced ​​arched wall panel is spliced ​​by a wet connection structure or a dry welding connection structure.

[0008] Preferably, the wet connection structure has exposed lapped steel bars at the connection ends of adjacent arched wall panels; a cast-in-place section is provided between two adjacent connection ends, and the cast-in-place section connects the adjacent lapped steel bars into a whole by post-cast concrete.

[0009] Preferably, the dry welding connection method includes pre-embedding a connecting steel plate at the connection end of the arched wall panel; the connecting steel plate between two adjacent connection ends is fixed by welding.

[0010] Preferably, it further includes a sealing and moisture-proof structure, which includes a joint sealing part and a surface moisture-proof layer. The joint sealing part is disposed at the splice of adjacent arched wall panels and on the contact surface between the support and the wedge-shaped column. The surface moisture-proof layer is coated on the surface of the arched wall panel facing outward. Under pressure, the arched wall panel uses its full-section compressive stress characteristics to squeeze the joint sealing part to achieve an airtight seal.

[0011] Preferably, the surface moisture-proof layer is a penetrating crystalline waterproof coating or polymer cement waterproof mortar.

[0012] The beneficial effects of this utility model are as follows: The arched wall panel provided by this utility model can be cast integrally on site or prefabricated in the factory and assembled on site. Under the same concrete usage, its load-bearing capacity is at least 30% higher than that of ordinary flat wall panels of the same thickness. Moreover, the deflection can be reduced by more than 50%.

[0013] When the inner side of the arched wall panel is under load, the stress on the entire outer arched surface is compressive stress, so no cracks will appear on the outside of the wall panel. This naturally ensures the airtightness, waterproof and moisture-proof performance of the wall panel itself.

[0014] Furthermore, since the entire cross-section of the arched wall panel is under compressive stress, when the length of the wall requiring prefabricated wall panels is large, it can be prefabricated in sections and spliced ​​on site, which can also ensure the stress, airtightness, waterproofness, and moisture-proof performance of the wall panel.

[0015] By utilizing the characteristic that the entire cross-section of the arched wall panel is under compressive stress, the amount of steel reinforcement can be reduced by increasing the concrete strength, thereby lowering the cost. It can be used in combination with ultra-high performance concrete to further reduce the amount of concrete and steel reinforcement, thus saving materials and energy. Attached Figure Description

Figure 3 This is a schematic diagram of a wet connection structure for wall splicing; Figure 4 This is a schematic diagram of a dry-welded connection structure for wall splicing.

[0017] The following labels are used in the diagram: wedge-shaped column 1; arched wall panel 2; cavity structure 201; mounting platform 101; lapped reinforcing bar 202; post-cast concrete 203; connecting steel plate 204. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below.

[0019] Example 1: As Figure 1 and Figure 2 As shown, this disclosure presents a single-story warehouse arched wall structure, mainly composed of wedge-shaped columns 1 and arched wall panels 2.

[0020] The wedge-shaped column 1 has a mounting platform 101 on both sides, with the mounting platform 101 facing the inside of the warehouse. For example, in the actual construction of a flat warehouse, the wedge-shaped column 1 can be made of high-strength post-cast concrete 203 to ensure that it can withstand the loads from the arched wall panel 2 and other related loads.

[0021] The arched wall panel 2 is vertically installed between two adjacent wedge-shaped columns 1. The side facing inwards is a flat plane, which directly bears the load generated by the stored grain and other materials inside the warehouse; the side facing outwards is arched. Supports are provided at both ends of the arched wall panel 2, and the supports are engaged with the mounting platforms 101 of the wedge-shaped columns 1.

[0022] The support has a cavity structure 201 inside to reduce its own weight. In this embodiment, in order to effectively reduce the weight of the support while ensuring its structural strength, various arrangements of the cavity structures 201 are adopted.

[0023] Vertical through-type setting: Within the support range, a cavity structure 201 is vertically through-type setting along the height direction of the arched wall panel 2, which reduces the self-weight of the support without excessively weakening its vertical bearing capacity.

[0024] Equal spacing in the width direction: The cavity structure 201 is arranged at equal intervals in the width direction of the arched wall panel 2, which reduces weight while ensuring the structural uniformity of the support in the width direction.

[0025] Different cross-sectional shapes: The cross-section of the cavity structure 201 is circular, rectangular or oblong. Different shapes of cavity structures 201 can be selected and combined according to actual stress analysis and the convenience of construction technology.

[0026] In addition, the cavity structure 201 is filled with foam strips or has hollow holes. In some bungalows where sound and heat insulation are required, foam strips, such as polystyrene foam strips, can be used as filling, as they have good sound and heat insulation properties and can effectively improve the performance of the bungalow. If weight reduction and cost reduction are the primary concerns, a hollow hole form can be used directly.

[0027] Example 2: Figure 3 and Figure 4 As shown, in this embodiment, the arched wall panel 2 is a spliced ​​structure with a broken middle section. The middle section of the spliced ​​arched wall panel 2 is spliced ​​through a wet connection structure or a dry welding connection structure.

[0028] The wet connection structure features exposed lapped reinforcing bars 202 at the connection ends of adjacent arched wall panels 2. A cast-in-place section is provided between two adjacent connection ends, and this section connects the adjacent lapped reinforcing bars 202 into a whole by post-cast concrete 203. During on-site construction, the adjacent arched wall panels 2 are first positioned so that the lapped reinforcing bars 202 are staggered. Then, formwork is erected, and post-cast concrete 203 is poured to form the cast-in-place section, connecting the lapped reinforcing bars 202 into a whole, ensuring the strength and integrity of the arched wall panel 2 joint.

[0029] The dry welding connection method involves pre-embedding connecting steel plates 204 at the connection ends of the arched wall panels 2; the connecting steel plates 204 between adjacent connection ends are fixed by welding, and several anchoring steel bars are installed on the steel plates to reliably connect with the arched wall panels 2 and the subsequently poured concrete 203. On the construction site, the connecting steel plates 204 of adjacent arched wall panels 2 are aligned and welded firmly using welding methods such as manual arc welding or gas shielded welding, thereby achieving the splicing of the arched wall panels 2. This connection method offers fast construction speed and is suitable for projects with tight schedules.

[0030] The arched wall structure of the flat warehouse in this embodiment also includes a sealing and moisture-proof structure, which includes a joint sealing part and a surface moisture-proof layer.

[0031] The joint sealing parts are located at the splicing points of adjacent arched wall panels 2, and on the contact surfaces between the supports and wedge-shaped columns 1. For example, at the splicing points of adjacent arched wall panels 2, silicone sealant can be used to seal the joint, filling the gaps to ensure a good seal and prevent moisture penetration. On the contact surfaces between the supports and wedge-shaped columns 1, rubber sealing strips can be adhered. The pressure generated when the arched wall panels 2 are compressed causes the rubber sealing strips to fit tightly against the contact surfaces, achieving a seal.

[0032] A surface moisture-proof layer is applied to the outer surface of the arched wall panel 2. This layer is either a penetrating crystalline waterproof coating or a polymer cement waterproof mortar. Taking a penetrating crystalline waterproof coating as an example, it is evenly applied to the surface of the arched wall panel 2 to form a continuous and dense waterproof coating, effectively preventing external moisture from penetrating the arched wall panel 2. When the arched wall panel 2 is under pressure, its full-section compressive stress characteristics compress the joint sealing area to achieve airtightness. For example, when grain stored inside the warehouse exerts pressure on the arched wall panel 2, it expands outwards, thereby compressing the sealing material at the joints, further improving the sealing effect and ensuring the airtightness, waterproofing, and moisture-proofing performance of the flat warehouse.

[0033] As demonstrated by the above embodiments, the arched wall structure of this flat warehouse fully leverages its structural advantages in practical applications. The arched wall panels can be cast integrally on-site, suitable for smaller flat warehouse projects with favorable construction site conditions; alternatively, they can be prefabricated in a factory and assembled on-site, suitable for large-scale, standardized flat warehouse construction. With the same amount of concrete, the load-bearing capacity is at least 30% higher than that of ordinary flat wall panels of equal thickness, and deflection can be reduced by more than 50%. Because the stress on the entire arched surface of the arched wall panel 2 is compressive stress under load on the inner side, no cracks will appear on the exterior of the wall panel, naturally ensuring its airtightness and waterproof and moisture-proof performance. Furthermore, utilizing the characteristic of compressive stress across the entire cross-section of the arched wall panel 2, the amount of steel reinforcement can be reduced by increasing the concrete strength, thereby lowering costs. When combined with ultra-high performance concrete, the amount of concrete and steel reinforcement used is further reduced, resulting in material and energy savings. Meanwhile, the cavity structure 201 of the support effectively reduces its own weight, the splicing structure facilitates construction, and the sealed and moisture-proof structure ensures the performance of the flat warehouse, making it practical and economical in actual applications.

[0034] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
