Description

Technical Field

[0001] The present invention belongs to the technical field of wall panels, and particularly relates to a light steel UHPC composite wall panel structure and a production and installation method thereof. Background Art

[0002] In the fields of wall panels for low-rise houses and external wall panels for exterior enclosure, the disadvantages of wall panels with different structural systems are as follows:

[0003] 1. PC structure: High costs are caused by factory hardware investment, standardization requirements, mold amortization, etc. At the same time, components also have problems such as limited transportation radius, the need for road facilities supporting during transportation and installation, and high transportation costs.

[0004] 2. Steel frame structure: The degree of factory integration is low, the workload of high-precision on-site installation is large, and professional skills are required. Moreover, there are problems such as different thermal expansion coefficients of the main structure and the maintenance structure, differences in strength and stiffness, etc., resulting in easy cracking of the exterior wall, as well as fire prevention and corrosion resistance, etc.

[0005] 3. Existing light steel structures: There are problems such as stiffness and comfort, durability problems caused by improper construction methods, inability to hang on the wall cavity, quality control of loose part installation, sound insulation and fire prevention, etc.

[0006] For the field of external wall panels for exterior enclosure:

[0007] 1. PC (precast concrete) wall panels: First, they are relatively heavy, resulting in a large load on the main structure and an increase in the amount of structural steel used; second, due to the requirements of building waterproofing structures, it is difficult to arrange edge insulation for the wall panels, and there are cold bridges; third, the price of thermal insulation tie pieces is relatively high. The cost of PC molds is relatively high. Therefore, the overall cost of PC wall panels is relatively high and the process is relatively complex. Due to requirements such as flexural strength requirements and steel bar protection layer thickness requirements, the thickness of ordinary concrete generally cannot be less than 5 cm, resulting in too heavy wall panels.

[0008] 2. Glass curtain walls: The building appearance is relatively single, the cost is relatively high, and there is light pollution. Therefore, they are mostly used in high-end office buildings. And with the development of prefabricated buildings, there is a trend of being partially replaced.

[0009] 3. Dry-hung curtain walls: Most use stone materials, which are heavy and costly. And they are easily contaminated. For other dry-hung panels, there are certain problems with the overall durability and it is also difficult to meet the requirements of the building appearance.

[0010] Therefore, there is a need for a wall panel structure that can be used in the above-mentioned usage scenarios and has the characteristics of light weight, high strength, simple preparation process, and low cost.

[0011] The patent document with the publication number CN113374209A discloses a connection method between a UHPC exterior wall panel and a back-mounted steel frame, which can achieve self-leveling after pouring and reduce the weight by reducing the thickness of the wall panel.

[0012] The patent document with the publication number CN115233899A discloses a UHPC precast wall panel and its construction method. The UHPC precast wall panel uses a steel bar skeleton to position the sound insulation board, and there is no need to install a special sound insulation board positioning frame to position the sound insulation board during production and processing.

[0013] However, the above patents do not cover the installation method in specific usage scenarios and the preparation of the thermal insulation structure. Summary of the Invention

[0022] Preferably, the tie rod includes a screw rod and a second connecting member, both ends of the second connecting member are respectively threadedly connected to the screw rod, and one end of the screw rod is connected to the light steel composite wall panel.

[0023] A production method of a light steel UHPC composite wall panel structure includes the following steps:

[0024] S1: Produce the formwork for the fixed plate. Clean and mark lines on the assembly line table formwork or the fixed table formwork, and arrange the side formwork according to the dimensions of the design drawing to form a mold.

[0025] S2: Set reinforcement members in the mold and set cushion blocks between the reinforcement members and the table formwork.

[0026] S3: Arrange embedded parts, first connectors, and installation embedded hanging nails on the reinforcement members, and then pour concrete into the mold to form an integral body for connecting with the keel. The arrangement of the embedded parts is close to the table formwork to ensure that the embedded parts can be exposed after pouring high-strength concrete, facilitating the connection with the keel, and the fixed plate is obtained by pouring.

[0027] S4: Assemble the keel according to the design drawing. After the concrete fixed plate is formed, connect the keel with the fixed plate.

[0028] S5: Set a filling layer and clamping parts in the grid of the keel. The gap between the filling layer and the keel is sealed with foamed polyurethane, and the keel is connected with the external wall panel through the clamping parts to complete the preparation of the light steel UHPC composite wall panel structure.

[0029] When the light steel UHPC composite wall panel structure is used as the main structure of the house, the installation method includes the following steps:

[0030] S1: Confirm the quantity of the required light steel UHPC composite wall panel structures according to the installation requirements. At this time, the external wall panel is not set on the light steel UHPC composite wall panel structure. When set horizontally, adjacent light steel UHPC composite wall panel structures are connected by columns.

[0031] S2: When set vertically, adjacent light steel UHPC composite wall panel structures are connected by truss beams.

The production process does not require customized side molds and standardized production, so it can be applied to wallboard specifications of various sizes. The mold cost amortization is reduced, and the manufacturing cost is relatively low. When used as a main load-bearing component of a low-rise structure, the keel and the fixed plate are forced together, the stability of the keel and the fixed plate is enhanced, and the fixed plate and the keel jointly bear the vertical load. When used as a protective hanging panel, the keel serves as the wallboard skeleton and can also be used as a fulcrum for dry hanging of the exterior wall. The dry hanging method of the exterior hanging panel further ensures the waterproof performance of the wallboard, and the secondary keel clamps used for dry hanging further enhance the stability of the keel.

Specific implementation mode

[0065] The technical solution of the present invention will be further described below, but the scope of protection is not limited thereto.

[0066] Embodiment:

[0067] As Figures 1 to 3 shown, a light steel UHPC composite wall panel structure includes a light steel composite wall panel, and the light steel composite wall panel includes an external wall panel 1, a keel 3 and a fixing plate. A clamping part 2 is arranged on one side of the keel 3, and the keel 3 is connected to the external wall panel 1 through the clamping part 2. The other side of the keel 3 is connected to the fixing plate. The fixing plate includes a reinforcement part 5 and a main body plate 7. The reinforcement part 5 is arranged inside the main body plate 7, and an embedded part 4 and a first connecting part 6 are arranged on the main body plate 7.

[0068] The keel 3 is made of light steel keel, and the keel 3 is a frame structure. The thickness I of the main body plate 7 can be 2 - 3 cm. The main body plate 7 is made of UHPC. The reinforcement part 5 can be a mesh structure composed of steel bars for strengthening the fixing plate.

[0069] A number of grids 31 are arranged inside the keel 3, and a filling layer 32 is arranged inside the grid. The filling layer 32 is made of rock wool for heat preservation.

[0070] Through holes are arranged on the clamping part 2, which can be used to be connected and fastened to other structures through bolts. The clamping part 2 is arranged in an L shape.

[0071] A placing groove 71 is arranged on the main body plate 7. The first connecting part 6 is arranged inside the placing groove 71. The first connecting part 6 is arranged in an L shape. Through holes can be arranged on the first connecting part 6, which can be used to be connected and fastened to other structures through bolts.

[0072] A light steel UHPC composite wall panel structure includes a column 8. The column 8 is connected to the keel 3. The column 8 is a rectangular tube with holes on the side. The sides of two light steel composite wall panels are connected through the column 8 and corresponding screws. The holes on the column 8 are used as hand holes for self-tapping screw connection. The holes can be sealed with foamed polyurethane after installation. This connection method can realize the disassembly of the light steel UHPC composite wall panel structure, which is convenient for recycling.

[0073] A light steel UHPC composite wallboard structure includes a truss beam 9 made of steel. The truss beam 9 is connected to the light steel composite wallboard. A tension rod 10 is provided on the truss beam 9. Both ends of the tension rod 10 are respectively connected to the light steel composite wallboard, and multiple layers of light steel composite wallboards are arranged through the truss beam 9.

[0074] The tension rod 10 includes a screw rod 101 and a second connecting piece 102. Both ends of the second connecting piece 102 are respectively threadedly connected to the screw rod 101. One end of the screw rod 101 is connected to the first connecting piece 6 of the light steel composite wallboard. After the screw rod 101 passes through the through hole of the first connecting piece 6, it can be connected and fastened with a nut. By rotating the second connecting piece 102, the length of the tension rod 10 is adjusted, and then the magnitude of the tension formed by the tension rod 10 on the light steel composite wallboard is adjusted.

[0075] As Figures 4 to 11 shown, a production method of a light steel UHPC composite wallboard structure includes the following steps:

[0076] S1: Fix the formwork for the production of the fixed plate. On the assembly line table formwork or the fixed table formwork, clean and mark lines, and arrange the side formwork according to the dimensions of the design drawing to form a mold 11;

[0077] S2: Set a reinforcement member 5 in the mold. The reinforcement member 5 is a steel mesh sheet, which is an automated formed product. A spacer is set between the reinforcement member 5 and the table formwork to form a 15-mm spacing, facilitating the formation of the concrete protective layer thickness;

[0078] S3: Arrange embedded parts 4, first connecting pieces 6, and installation embedded lifting nails 12 on the reinforcement member 5. The embedded lifting nails 12 are set at 1 / 4 of the length of the fixed plate from the edge for demolding after the concrete is formed. Then, pour UHPC ultra-high performance concrete into the mold, that is, concrete with a compressive strength generally above 120 Mpa. After that, it forms an integral body for connecting with the keel 3 made of light steel C89 model. The embedded part 4 consists of a small section of thin-walled steel pipe and an anchor reinforcing bar calf. The embedded part 4 is arranged closely against the table formwork to ensure that the embedded part 4 can be exposed after pouring high-strength concrete, facilitating the connection with the keel 3, and the fixed plate is obtained by pouring;

[0079] S4: Assemble the keel 3 according to the design drawing. The assembly of the keel 3 does not need to wait for the aforementioned concrete pouring process and can be carried out separately. After the UHPC ultra-high performance concrete fixed plate is formed, connect the keel 3 with the fixed plate. Both the assembly connection of the keel 3 and the connection between the keel 3 and the fixed plate are connected by self-tapping screws 13;

[0080] S5: Set a filling layer 32 and a clamping part 2 in the grid 31 of the keel 3. The gap part between the filling layer 32 and the keel 3 is sealed with foamed polyurethane to ensure no cold and heat bridges. Connect the keel 3 with the external wall board 1 through the clamping part 2 to complete the preparation of the light steel UHPC composite wallboard structure.

[0081] As Figures 12 to 21 shown, when the light steel UHPC composite wallboard structure is used as the main structure of a low-rise building, the installation method includes the following steps:

[0082] S1: Confirm the quantity of the required light steel UHPC composite wallboard structure according to the installation requirements. At this time, the external hanging board 1 is not set on the light steel UHPC composite wallboard structure. When arranged horizontally, adjacent light steel UHPC composite wallboard structures are connected by columns 8. Holes are drilled on the sides of the columns 8 for connecting and fastening with the light steel UHPC composite wallboard structure through self-tapping screws, and the holes are blocked with foamed polyurethane later;

[0083] S2: When arranged vertically, adjacent light steel UHPC composite wallboard structures are connected by truss beams 9. At this time, the external hanging board 1 is not set on the light steel UHPC composite wallboard structure. The tension bolts 10 are pre-embedded in the truss beams 9 in advance. The light steel UHPC composite wallboard structure and the truss beam 9 are temporarily fixed with self-tapping screws. After two layers of light steel UHPC composite wallboard structures are in place, the two layers of light steel UHPC composite wallboard structures are vertically tied with the tension bolts 10;

[0084] S3: The external hanging board 1 is connected to the keel 3 through self-tapping screws 13 and fasteners 2. On the one hand, the fasteners 2 horizontally connect the vertical keels that make up the keel 3, strengthening the stability of the vertical keels. At the same time, the fasteners 2 also serve as the fasteners for dry-hanging the external hanging board 1. Normally, the fasteners 2 can be in the shape of a capital "J". However, when the last piece of the external hanging board 1 is dry-hung, or when encountering a hole shape, when the upper and lower external hanging boards 1 are already fixed and it is difficult to install the external hanging board 1, or when the tolerance is large and local tolerance needs to be absorbed, the capital "J"-shaped fasteners 2 need to be disassembled into the first fastener 21 and the second fastener 22. The first fastener 21 and the second fastener 22 can be arranged in a "Z" shape. The first fastener 21 and the second fastener 22 are combined to form a capital "J"-shaped fastener. The height of the capital "J"-shaped fastener formed after combination can be adjusted to facilitate the external hanging of the external hanging board 1. After the last piece of the external hanging board 1 is positioned, the capital "J"-shaped fastener formed by the combination of the first fastener 21 and the second fastener 22 is fixed on the vertical keel that makes up the keel 3 through self-tapping screws 13, and then the external hanging board 1 is hung to complete the dry-hanging process.

[0085] As Figures 22 to 25 shown, when the light steel UHPC composite wallboard structure is used as the secondary structure enclosure hanging board, the installation method includes the following steps:

[0086] S4: The light steel UHPC composite wallboard structure is connected to the fixed beam 15 through the pre-embedded first connecting piece 6 and angle steel 14. When the fixed beam 15 is a concrete beam, the angle steel 14 is pre-embedded on the fixed beam 15 in advance;

[0087] S5: The joint connection between the light steel UHPC composite wallboard structures requires a good waterproof structure. When the light steel UHPC composite wallboard structures are vertically arranged, seals 18 are respectively arranged on one side of the bottom floor joist 16 and one side of the top ceiling joist 17 of adjacent light steel UHPC composite wallboard structures. The seal 18 can be a rectangular steel pipe. The seal 18 is tightly connected to the bottom floor joist 16 and the top ceiling joist 17 by self-tapping screws 13. A sealing strip 19 is arranged between the two seals 18. The material of the sealing strip 19 is plastic, which plays a waterproof role. The diameter of the sealing strip 19 is 1 cm higher than the height of the tongue-and-groove. This setting forms an overall flexible flat joint, which has a good two-way waterproof structure.

[0088] The angle steel 14 is arranged in an L shape and is composed of two connected steel sheets. The angle steel 14 can be connected and fastened to the light steel UHPC composite wallboard structure or the fixed beam 15 by bolts passing through the angle steel 14.

[0089] The present invention is applicable to low-rise houses as the main load-bearing structure; and various types of building exteriors, such as office buildings, hotels, hospitals, factories, apartments, etc., including steel structure exteriors, light and heavy steel combined structure enclosing walls, etc. in many building fields as secondary enclosing structures, and does not bear the load together with the main structure.
