Description

Technical Field

[0001] This utility model relates to the technical field of building construction, specifically to a steel mesh structure for building construction of ground-floor houses that integrates earthquake resistance and thermal insulation. Background Technology

[0002] In the construction of ground-floor houses and villas, the synergistic improvement of seismic resistance and thermal insulation performance has always been a core focus of the industry's technological breakthroughs. However, current traditional construction methods have significant technical bottlenecks: on the one hand, structural seismic resistance relies on a combination of concrete pouring and steel mesh laying; however, the material properties of steel and concrete result in poor synergistic stress distribution, making them prone to cracks and deformation under seismic loads. This is especially pronounced at the beam-column joints of ground-floor houses, where stress concentration is prominent, making it difficult to guarantee the overall structural stability.

[0003] On the other hand, the thermal insulation function is mostly achieved by pasting insulation boards later. This type of external insulation layer has low bonding strength with the main structure. Affected by factors such as temperature changes and structural settlement, it is very easy to produce quality problems such as hollowing and falling off. Moreover, the insulation material itself does not have a structural support function and cannot participate in the overall load-bearing system.

[0004] In addition, the phased construction mode not only prolongs the construction period and increases labor and material costs, but also makes it difficult to solve the energy loss problem caused by thermal bridging. As a result, ground floor buildings generally face multiple challenges such as insufficient seismic safety, rapid decay of insulation effect, and low living comfort. There is an urgent need for an integrated and collaborative innovative structural design to break through the limitations of existing technology. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing low-rise building construction, such as difficulty in integrating seismic resistance and thermal insulation, poor synergy of tensile and compressive strength of the structure, and insufficient stability of the insulation layer. It provides a steel mesh structure for building construction, which achieves synergistic improvement of the seismic resistance and thermal insulation performance of low-rise buildings, while simplifying the construction process and reducing construction costs.

[0006] To achieve the above objectives, the following technical solution is provided:

[0007] A steel mesh frame structure for building construction includes a frame body. The frame body consists of a top plate at the upper end, a bottom plate at the lower end, and a left vertical plate and a right vertical plate connected between the top plate and the bottom plate. The top plate and the bottom plate have the same structural dimensions. Support plate one, support plate two, support plate three, and support plate four are also provided between the left vertical plate and the right vertical plate. Barrier plate structures are sequentially provided in the middle of both sides of the left vertical plate, the right vertical plate, support plate one, support plate two, support plate three, and support plate four. Several steel reinforcement structures are provided between support plate one, support plate two, support plate three, and support plate four.

[0008] Preferably, the top plate includes, from right to left, a first top plate 21, a second top plate, a third top plate, a fourth top plate, and a fifth top plate, with the width decreasing sequentially.

[0009] Preferably, the widths of the first top plate, the second top plate, the third top plate, the fourth top plate, and the fifth top plate correspond one-to-one with the widths of the fourth support plate, the third support plate, the second support plate, the left vertical plate, and the first support plate.

[0010] Preferably, the barrier plate structure includes a parallel barrier plate disposed between the support plate four and the right vertical plate, and an oblique barrier plate disposed between the support plate four and the left vertical plate.

[0011] Preferably, the angle between the oblique barrier plate and the parallel barrier plate is 15-30 degrees.

[0012] Preferably, the support plate four and the right vertical plate are separated by parallel barrier plates to form a hollowed-out section with vertical spacing.

[0013] Preferably, the left vertical plate, right vertical plate, support plate one, support plate two, support plate three, and support plate four are injected with insulation material to form an insulation layer with the barrier plate structure.

[0014] Preferably, the steel reinforcement structure is disposed on both sides of the insulation layer, and concrete is filled between the insulation layer, the steel reinforcement structure and the frame body.

[0015] Compared with the prior art, the steel mesh structure for house construction of this utility model has the following beneficial effects:

[0016] Integrated earthquake resistance and thermal insulation: Through a three-layer collaborative structure of steel mesh frame + thermal insulation layer + concrete, the steel mesh frame with steel reinforcement ensures the tensile performance of the structure, the concrete ensures the compressive strength, and the middle thermal insulation layer provides thermal insulation. The three form an overall earthquake-resistant frame, which completely solves the problem of the traditional separate implementation of earthquake resistance and thermal insulation in houses, and realizes integrated design.

[0017] High structural stability:

[0018] The segmented design of the top slab corresponds one-to-one with the width of the supporting structure below, avoiding localized stress concentration; the angle design of the inclined baffle plate and the parallel baffle plate at 15-30 degrees can effectively disperse horizontal seismic stress; the cross-mesh distribution of the steel reinforcement further enhances tensile synergy, significantly improving the overall seismic resistance level of the structure and ensuring the house is sturdy and durable.

[0019] Long-lasting heat retention:

[0020] The insulation layer is injected into the enclosed area formed by the frame body and the barrier plate, and is reinforced with steel bars and concrete on both sides to prevent the insulation layer from falling off or cracking; the enclosed structure reduces air convection, and the insulation performance is stable, which can make the house warm in winter and cool in summer, and improve the living comfort.

[0021] Easy to construct and low cost:

[0022] The integrated structural design reduces the step-by-step process of pouring the main body and pasting the insulation layer in traditional construction, shortening the construction cycle; each component can be prefabricated and assembled on site, and then the insulation material and concrete can be directly injected and filled, reducing labor and material costs.

[0023] Good functional expandability:

[0024] The openwork between the fourth support plate and the right vertical plate can be directly used to install windows or reserve openings without additional construction excavation, simplifying the construction process for the functional layout of the house and improving the practicality and flexibility of the structure.

[0033] like Figure 1 As shown in Figure 3, a steel mesh structure for building construction includes a frame body, a barrier plate structure, a steel reinforcement structure, an insulation layer, and a concrete filling layer. Its specific structural features are as follows:

[0034] Framework structure:

[0035] The frame body is an integral load-bearing foundation, consisting of a top plate 2 at the upper end, a bottom plate 9 at the lower end, and a left vertical plate 6 and a right vertical plate 1 connecting the top plate 2 and the bottom plate 9; the top plate 2 and the bottom plate 9 have the same structural dimensions to ensure that the frame is subjected to balanced forces.

[0036] Between the left vertical plate 6 and the right vertical plate 1, support plates 1, 2, 3, and 4 are arranged sequentially along the horizontal direction. The vertical plates and support plates together form the longitudinal and transverse support system of the frame body, which improves the overall stability of the structure.

[0037] Segmented design of the top slab

[0038] The top plate 2 is arranged in a stepped manner from right to left, including a first top plate 21, a second top plate 22, a third top plate 23, a fourth top plate 24, and a fifth top plate 25, with the width of each segment decreasing from right to left. Furthermore, the width of the first top plate 21 is the same as the width of the fourth support plate 3, the width of the second top plate 22 is the same as the width of the third support plate 8, the width of the third top plate 23 is the same as the width of the second support plate 4, the width of the fourth top plate 24 is the same as the width of the left vertical plate 6, and the width of the fifth top plate 25 is the same as the width of the first support plate 5. This design ensures that the top plate is completely fitted with the supporting structure below, avoiding localized stress concentration.

[0039] Barrier plate structure and perforated parts

[0040] On both sides of the left vertical plate 6, the right vertical plate 1, the first support plate 5, the second support plate 4, the third support plate 8, and the fourth support plate 3, a barrier plate structure 10 is fixedly installed in sequence along the vertical direction. The barrier plate structure 10 includes two types: one is a parallel barrier plate 101 set between the fourth support plate 3 and the right vertical plate 1, and the other is an oblique barrier plate 102 set between the fourth support plate 3 and the left vertical plate 6. The included angle between the oblique barrier plate 102 and the parallel barrier plate 101 is 15-30 degrees, preferably 20 degrees, which can disperse the horizontal seismic stress through the tilt angle.

[0041] Meanwhile, the parallel barrier plates 101 between the support plate 4 3 and the right vertical plate 1 are distributed at intervals along the vertical direction, forming a hollowed-out part 11 with intervals between the upper and lower parts. This hollowed-out part not only facilitates the subsequent injection of thermal insulation material, but also reduces the self-weight of the structure, without affecting the overall strength. The hollowed-out part can also be used to install windows or reserve openings.

[0042] Reinforcing bars and multi-layer collaborative structure

[0043] Several steel reinforcement structures 7 are fixedly installed between support plate 1 5, support plate 2 4, support plate 3 8 and support plate 4 3 respectively. The steel reinforcement structures 7 are distributed in a cross mesh pattern to further improve the tensile performance of the frame body.

[0044] In the enclosed area enclosed by the left vertical plate 6, the right vertical plate 1, each support plate and the barrier plate structure 10, thermal insulation material, such as flame-retardant polystyrene board, rock wool, etc., is injected to form an insulation layer; the steel reinforcement structure 7 is symmetrically arranged on both sides of the insulation layer, and concrete is filled in the gap between the insulation layer, the steel reinforcement structure 7 and the frame body, finally forming a three-layer synergistic integrated structure of steel mesh frame tensile strength - thermal insulation layer insulation - concrete compressive strength.

Top plate 2 and bottom plate 9 are both welded with HRB400 grade steel bars. The width of the first top plate 21 to the fifth top plate 25 of top plate 2 is 6cm, 8cm, 10cm, 15cm and 12cm respectively, which corresponds to the width of the support plates and vertical plates below.

[0050] Reinforcing bar structure 7: HRB335 grade steel bars are used to make cross bars with a diameter of 12mm and a cross angle of 45 degrees.

[0051] Frame assembly

[0052] First, fix the base plate 9 horizontally, and then weld the right vertical plate 1 and the left vertical plate 6 to both ends of the base plate 9 respectively;

[0053] Along the length of the base plate 9, support plate 3, support plate 8, support plate 4, and support plate 5 are welded in sequence, with the spacing between adjacent support plates and vertical plates being 0.8m.

[0054] At the middle of both sides of each vertical plate and support plate, a set of barrier plate structures 10 is welded every 50cm along the vertical direction. Among them, a parallel barrier plate 101 is welded between the support plate 4 3 and the right vertical plate 1 to form a hollow part 11 with a height of 30cm. This hollow part can be used to install windows or reserve openings. An oblique barrier plate 102 is welded between the support plate 4 3 and the left vertical plate 6.

[0055] Weld steel reinforcement structure 7 between each support plate to ensure that 4 sets of cross reinforcement are set in each square meter area;

[0056] Finally, weld the top plate 2 to the top of each vertical plate and support plate, ensuring that each segment of the top plate is perfectly aligned with the width of the support below.

[0057] Insulation layer and concrete filling

[0058] Flame-retardant polystyrene board particles are injected into the enclosed area formed by the frame body and the barrier board structure 10, and after compaction, a thermal insulation layer with a thickness of 5-8cm is formed.

[0059] Between the steel reinforcement structure 7 on both sides of the insulation layer and the frame body, C30 commercial concrete is poured, vibrated to compact, and then cured according to standard conditions to finally form a complete steel mesh structure.

[0067] The base plate 9 is made of C25 precast concrete slab, which is suitable for rural construction conditions. Reinforcing bar connection points are reserved on the base plate, and the vertical plate and support plate are fixed by binding instead of welding, which is suitable for rural on-site construction capabilities.

[0068] A parallel barrier plate 101 is set at an 80cm interval between the support plate 4 3 and the right vertical plate 1, forming a 50cm high hollow part 11 for installing windows of the commonly used 1.5m×1.2m size in rural areas.

[0069] The steel reinforcement structure has 3 sets per square meter to reduce construction complexity.

[0070] Insulation layer and concrete filling

[0079] Frame assembly

[0080] The base slab 9 is integrally cast with the reinforced concrete strip foundation, and the vertical slab and the support slab are welded and fixed with embedded parts to ensure the joint strength under large span.

[0081] Three sets of parallel partition plates 101 are set between the support plate 4 3 and the right vertical plate 1 to form two hollow sections 11 with a height of 1.2m, which are used to install the shop roller shutter door with a width of 3m and the display window with a width of 2m respectively. Angle steel reinforcement frames are added to the edges of the hollow sections.

[0082] Diagonal supports are installed at both ends of the frame body at an angle of 45 degrees to the horizontal line to enhance the overall anti-overturning ability.
