Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a steel frame composite GFRC panel combined unit curtain wall installation construction structure. Background Technology

[0002] With the development of the construction industry, unitized curtain walls are widely used in modern buildings due to their advantages such as aesthetics and convenient construction. Among them, steel frame composite GFRC panel combined unitized curtain walls combine the high strength of steel frames with the decorative properties of GFRC panels, and are currently a commonly used curtain wall form.

[0003] However, existing installation structures for steel-framed composite GFRC panel unitized curtain walls still have many shortcomings. For example, traditionally, GFRC panels are mostly fixed to the steel frame with bolts. During installation, multiple people need to simultaneously align 4-6 bolt holes at a height, resulting in low installation efficiency. At the same time, the welding connection between the steel frames is prone to thermal deformation, causing errors during GFRC panel installation and easily leading to poor overall flatness of the curtain wall. Therefore, we propose an installation structure for steel-framed composite GFRC panel unitized curtain walls to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the low installation efficiency caused by the traditional installation method of fixing GFRC panels to steel frames with bolts and the easy occurrence of thermal deformation caused by welding between steel frames, which leads to installation errors. Therefore, a steel frame composite GFRC panel combined unit curtain wall installation construction structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steel frame composite GFRC panel combined unit curtain wall installation construction structure includes a steel frame, and the four inner corners of the steel frame are fixedly connected with fixing lugs with elongated oval holes;

[0007] One side of the steel frame is detachably connected to the composite panel via a snap-fit ​​assembly. The composite panel is a composite GFRC panel. The snap-fit ​​assembly includes four sliding blocks fixed to the composite panel and four slots opened in the steel frame. The inner wall of the slot away from the opening is set as an inclined surface, so that when the sliding blocks slide in, they are pushed tightly against the side wall of the slot by the horizontal component of the inclined surface to form a self-locking mechanism.

[0008] The top crossbeam of the steel frame is equipped with a limiting component, including a limiting block that is slidably disposed in a groove opened in the top crossbeam of the steel frame and two limiting slide rods that are fixedly disposed on the inner wall of one side of the groove. Each of the two limiting slide rods is fitted with a spring. Under the action of the spring, the limiting block is inserted into the limiting groove of the composite plate to achieve vertical locking.

[0009] The steel frame has fixing components on all four sides to facilitate fixing to adjacent steel frames. Each fixing component includes multiple fixing groove groups, wherein each fixing groove group consists of two symmetrically arranged wedge-shaped grooves, and each wedge-shaped groove is provided with a threaded hole. When two steel frames are spliced ​​together, the corresponding two wedge-shaped grooves on the two steel frames are connected.

[0010] In one possible design, the mounting assembly further includes four clearance slots formed in the steel frame, each clearance slot being located above and connected to the corresponding slot.

[0011] In one possible design, the limiting block is T-shaped, with its horizontal section slidably sleeved on two limiting slide rods, and the two ends of the spring respectively abutting the inner wall of the slide groove and the limiting block.

[0012] In one possible design, the horizontal component of the force generated by the contact between the inclined surface and the end face of the sliding block pushes the sliding block tightly against the inner wall of the other side of the slot to form a self-locking mechanism.

[0013] In one possible design, the fixing component further includes a wedge block, the two wedge-shaped end faces of which are respectively inserted into the wedge grooves of the adjacent steel frame, and a fixing bolt is threaded onto the wedge block, the fixing bolt passing through the wedge block and connecting to the threaded hole in the wedge groove.

[0014] In one possible design, a sealing strip is embedded in the sealing groove around the steel frame.

[0015] In one possible design, a continuous water channel is formed on the outer surface of the composite plate.

[0016] In this application, during installation, the steel frame is first fixed to the wall through the mounting holes on the fixing ears to achieve a stable connection between the steel frame and the main building, providing a foundation for subsequent installation. Then, the composite panel is installed by inserting the sliding block on the composite panel into the clearance groove on the steel frame that communicates with the slot, and sliding it vertically into the slot along the clearance groove. During the process, the limiting block retracts into the sliding groove under the pressure of the composite panel, and the spring is compressed. When the sliding block slides into the slot and engages with it, since the inner wall of the slot away from the opening is set as an inclined surface, the end face of the sliding block contacts the inclined surface and generates a horizontal component force, pushing the sliding block to press against the inner wall of the slot, forming a self-locking effect, and achieving the initial fixation of the composite panel and the steel frame. At the same time, the limiting block is inserted into the limiting groove of the composite panel under the elastic force of the spring, completing the vertical position fixation of the composite panel and further improving the stability of the composite panel installation.

[0017] When splicing adjacent steel frames, the two wedge-shaped end faces of the wedge block are inserted into the corresponding wedge grooves of the two adjacent steel frames, and then the fixing bolts are used to connect with the threaded holes in the wedge grooves to tightly fix the adjacent steel frames together, ensuring the flatness and overall stability of the steel frames after splicing. At the same time, the sealing strip between adjacent steel frames can effectively seal the gaps, and the water guide grooves on the composite panel can guide rainwater out in time, achieving a good waterproof effect and protecting the curtain wall structure and the interior environment of the building.

[0018] Beneficial effects: In this utility model, the steel frame composite GFRC panel combined unit curtain wall installation construction structure achieves rapid positioning of the composite panel through the vertical insertion design of the sliding block and the slot, combined with the guidance of the clearance groove. At the same time, the horizontal component force generated by the inclined surface in the slot pushes the block to lock itself, which significantly simplifies the installation process, reduces the installation difficulty, and improves the installation efficiency.

[0019] In this utility model, the steel frame composite GFRC panel combined unit curtain wall installation construction structure automatically inserts the limiting block into the limiting groove under the action of the spring, thereby completing the rapid vertical locking of the composite panel, further enhancing the connection firmness and stability, effectively resisting the action of external loads, and ensuring the safety of curtain wall use;

[0020] In this utility model, the steel frame composite GFRC panel combined unit curtain wall installation construction structure adopts a wedge groove and wedge block matching design for the fixing components. When the wedge end face of the wedge block is inserted into the corresponding wedge groove of the adjacent steel frame, the characteristics of the wedge structure can be used to adaptively adjust and fit tightly, effectively compensating for dimensional errors during the installation process, ensuring the flatness of the adjacent steel frames after splicing, improving the stability of the overall curtain wall structure, and enhancing its ability to resist external environmental loads.

[0021] In this invention, the composite panel is quickly positioned and self-locked by the cooperation of the sliding block and the slot and the guidance of the clearance groove, which simplifies the installation process and improves efficiency; the limiting block vertically locks the composite panel under the action of the spring, which enhances the connection stability and ensures the safety of the curtain wall; the wedge groove and the wedge block in the fixing component cooperate to adaptively adjust the fit, make up for errors, ensure flatness, and improve the overall stability and environmental resistance of the curtain wall.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In one embodiment: Refer to Figure 1-5 A curtain wall installation structure comprises a steel frame 1, a composite panel 2, a fixing lug 3, a limiting block 4, a limiting slide rod 5, a spring 6, a wedge block 7, a fixing bolt 8, a sealing strip 9, and a water guide groove 10.

[0030] The steel frame 1 is a rectangular frame structure formed by welding two crossbeams and two columns. Fixing lugs 3 are welded to the four inner corners of the frame. Each fixing lug 3 has an elongated oval mounting hole, through which expansion bolts are used to mechanically connect the steel frame 1 to the building wall. Four slots 102 are formed on the side wall of the steel frame 1 near the composite panel 2. Each slot 102 has a clearance groove 101 above it. The inner wall of the slot 102 away from the opening is machined into a sloped structure. When the sliding block 201 of the composite panel 2 slides into the slot 102 along the clearance groove 101, the end face of the sliding block 201 contacts the sloped surface, generating a horizontal force that pushes the sliding block 201 tightly against the inner wall of the other side of the slot 102, creating a self-locking effect and ensuring a stable connection between the composite panel 2 and the steel frame 1.

[0031] The composite panel 2 is made of GFRC (glass fiber reinforced concrete), and four sliding blocks 201 are installed on its side wall near the steel frame 1. During installation, the sliding blocks 201 are guided into the slots 102 through the clearance grooves 101, and slide vertically down the slots 102 under gravity until they are fully engaged. The side wall of the composite panel 2 has a limiting groove 202. When the sliding blocks 201 reach the bottom of the slots 102, the limiting grooves 202 are aligned with the sliding grooves 103 on the crossbeam of the steel frame 1.

[0032] A limiting assembly is installed on the top crossbeam of the steel frame 1. A limiting block 4, two limiting slide rods 5, and a spring 6 are configured within the slide groove 103. The limiting block 4 has a T-shaped structure, with its horizontal section slidingly fitted around the outer periphery of the two limiting slide rods 5, and one end extending to the outside of the steel frame 1. The spring 6 is fitted around the outside of the limiting slide rods 5, with its two ends abutting against the inner wall of the slide groove 103 and the end face of the horizontal section of the limiting block 4, respectively. When the composite panel 2 is installed in place, the limiting block 4 automatically inserts into the limiting groove 202 under the elastic force of the spring 6, forming a vertical constraint on the composite panel 2.

[0033] Each of the four sides of the steel frame 1 has a fixing groove group, each group consisting of two symmetrically arranged wedge-shaped grooves 104. When adjacent steel frames 1 are spliced, the two wedge-shaped end faces of the wedge block 7 are inserted into the corresponding wedge-shaped grooves 104, and automatic alignment is achieved through the cooperation of the wedge-shaped surfaces. Two threaded through holes are opened in the middle of the wedge block 7. The fixing bolt 8 passes through the threaded through holes and engages with the threaded holes at the bottom of the wedge-shaped groove 104, completing the mechanical connection of adjacent steel frames 1. This connection method can compensate for ±2mm installation error through the self-adaptive characteristics of the wedge structure, ensuring the flatness of the curtain wall surface.

[0034] This application can be used in the field of building curtain wall technology, or in other fields applicable to this application.

[0035] In another embodiment: Reference Figure 1-2 Based on Example 1, an improvement is made to the following: a steel-framed composite GFRC panel unitized curtain wall installation structure, applied in the field of building curtain wall technology. The sealing strip 9, made of EPDM rubber, is embedded in the sealing grooves around the steel frame 1. When adjacent steel frames 1 are joined, the sealing strip 9 deforms under pressure to form a continuous sealing band, effectively preventing rainwater penetration. A water-guiding groove 10 is provided on the outer surface of the composite panel 2. The water-guiding groove 10 has a V-shaped cross-section and is arranged along the length of the composite panel 2, allowing rainwater on the curtain wall surface to be quickly guided to the drainage system, avoiding the risk of leakage due to water accumulation.

[0036] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
