Description

Technical Field

[0001] This invention relates to the field of building construction, specifically to a prefabricated steel structure building external formwork with sound absorption function. Background Technology

[0002] Compared to traditional concrete buildings, steel structure buildings use steel plates or profiles instead of reinforced concrete, resulting in higher strength and better earthquake resistance. Furthermore, because components can be factory-made and installed on-site, construction time is significantly reduced. The reusability of steel greatly reduces construction waste, making it more environmentally friendly. Therefore, it is widely adopted worldwide in both industrial and civil buildings. The external cladding technique involves attaching or hanging insulation materials to the exterior wall using adhesive mortar or specialized fasteners, then applying crack-resistant mortar, pressing in fiberglass mesh to form a protective layer, and finally adding a decorative finish.

[0003] Existing prefabricated building external formwork structures mostly use multiple steel plates spliced ​​and fixed together. However, these steel plates are large and have a simple structure, making them difficult to lift and position during hoisting, requiring subsequent adjustment and positioning procedures, resulting in a complicated overall installation process. Furthermore, the steel plates in existing technologies remain as individual structures after being installed externally, failing to form a more integrated whole structure, making the existing external formwork susceptible to detachment due to external factors. In addition, existing technologies often result in poor sound insulation of the walls, and the formwork is mostly fixed by welding steel bars, which is inefficient and inconvenient to use.

[0039] Example

[0040] Please see Figures 1-9 The present invention provides a prefabricated steel structure building external formwork with sound absorption function, comprising a formwork body 1;

[0041] The template body 1 includes a fixed frame 11, an outer wall panel 12 fixed to the front end of the fixed frame 11 for protection, an inner wall panel 13 fixed to the rear end of the fixed frame 11, an open through slot 14 provided on all four sides of the fixed frame 11, a pre-support member 15 fixed on all four sides of the fixed frame 11, a sealing member 16 inserted into the front end of the pre-support member 15 for sealing, and an adjusting member 17 rotatably provided inside the fixed frame 11.

[0042] The pre-support member 15 includes a concave thin iron 151 fixed to the left and bottom sides of the fixed frame 11, a screw cylinder 152 rotatably disposed in the through hole inside the concave thin iron 151, a polygonal through hole 153 disposed on the front side of the screw cylinder 152 for locking, a screw 154 threaded through the inner wall of the screw cylinder 152, an extrusion plate 155 rotatably disposed at the rear end of the screw 154, and a convex thin iron 156 fixed to the right and top sides of the fixed frame 11.

[0043] The sealing element 16 includes a cross plate 161 that is fixed to the front groove of the concave thin iron 151 by an external fastener, a rivet hole 162 for positioning on the front side of the cross plate 161, an adhesive groove 163 on the rear side of the cross plate 161, an adhesive injection hole 164 for injecting adhesive on the middle side of the front end of the cross plate 161, an adhesive guiding square tube 165 fixed on the middle side of the rear end of the cross plate 161, and tapered grooves 166 on the four sides of the adhesive guiding square tube 165 for guiding flow.

[0044] The adjusting component 17 includes a double-axis screw 171 rotatably disposed at the through holes of the outer wall panel 12 and the inner wall panel 13, a straight cylinder 172 rotatably disposed on the opposite sides of the outer wall panel 12 and the inner wall panel 13, a first adjusting plate 173 rotatably disposed on the outside of the straight cylinder 172, a second adjusting plate 174 rotatably disposed on the outside of the straight cylinder 172, screw grooves 175 disposed around the front ends of the first adjusting plate 173 and the second adjusting plate 174, a first filling plate 176 slidably disposed at the front end of the first adjusting plate 173, and a second filling plate 177 slidably disposed at the rear end of the second adjusting plate 174.

[0045] The concave thin iron 151 is arranged in a flat plate adjacent to the fixed frame 11, and the plate at the end away from the fixed frame 11 is arranged in a slope. The shape of the protrusion at the rear end of the convex thin iron 156 matches the inner slope of the concave thin iron 151, and the thickness of both the concave thin iron 151 and the convex thin iron 156 is half that of the fixed frame 11.

[0046] The rear end of the fixed frame 11 is provided with a fastening component for connecting with the steel structure building, and the fastening component is specifically composed of hinges and bolts.

[0047] The front end of the cross plate 161 is provided with adjacent rivet holes 162, which are spaced at the same distance from the screw cylinders 152 provided on the two adjacent sets of template bodies 1. The polygonal through holes 153 and rivet holes 162 are assembled and connected by external rivets.

[0048] The internal filling materials of the first filling plate 176 and the second filling plate 177 are specifically composed of a multi-layer structure core material composed of sound-absorbing cotton and foam plastic and a metal frame, and the metal frame is covered with a rubber layer on all four sides.

[0049] The working principle of a prefabricated steel structure building external formwork with sound absorption function based on Embodiment 1 is as follows:

[0050] When using this equipment, firstly, the material is stacked and transported in the work area using handling equipment, and power is supplied to the hoisting equipment, mixing equipment, and other equipment via cables; then, the sealing colloid required for subsequent steps is prepared using the aforementioned equipment.

[0051] Workers used lifting equipment to hoist the template body 1 to the lower corner of the steel structure building wall. Here, the template body 1 and the steel structure building wall were aligned by an external alignment instrument. The template body 1 was then fixed to the bottom corner of the steel structure building wall by the locking parts at the rear end of the fixed frame 11, and the template body 1 was used as the reference surface.

[0052] Then, by rotating the screw cylinder 152, it is driven by the screw 154 at the rear end to push the extrusion plate 155 to the rear side. The extrusion plate 155 is displaced and extrudes the concave thin iron 151, causing it to deform. The angle of the concave thin iron 151 to deform is the gap between the adjacent template body 1.

[0053] Then, the other template bodies 1 are hoisted to the adjacent work position of the template body 1 that serves as the reference surface in the previous steps. During the hoisting process, the convex thin iron 156 on the side of the hoisted template body 1 needs to be aligned with the concave thin iron 151 of the template body 1 that serves as the reference surface, and the concave thin iron 151 and the convex thin iron 156 are inserted to achieve the locking action, so as to pre-support and pre-fix the multiple sets of template bodies 1 at the adjacent work positions.

[0054] Then, by passing rivets through rivet holes 162 and polygonal through holes 153, the cross plate 161 is fixedly installed in the adjacent grooves of the pre-fixed multiple sets of template bodies 1. Then, the template bodies 1, which have been adjusted and positioned at adjacent work positions, are installed with the steel structure wall by using the locking parts set at the rear end of the fixed frame 11. At this time, the double-axis screw 171 can be rotated to drive the first adjusting plate 173 and the second adjusting plate 174 to slide inside the fixed frame 11, so that the first adjusting plate 173 and the second adjusting plate 174 squeeze the first filling plate 176 and the second filling plate 177 respectively, while forming a space with the fixed frame 11. Here, the first filling plate 176 and the second filling plate 177 provide sound insulation effect.

[0055] Then, the staff injects the pre-made sealant into the gaps between the adjacent sets of template bodies 1 and the space enclosed by the first filling plate 176 and the second filling plate 177 through the injection hole 164 and the guide tube 165. After it solidifies, it can provide sealing and integration for the template bodies 1 of the adjacent units, and at the same time, it solidifies into a cross plate 161 inside the adhesive groove 163 to provide installation and fixing effect.

[0056] Repeat the aforementioned steps to install multiple sets of template bodies 1 on the exterior walls of the steel structure building.

[0057] Example

[0058] Please see Figures 1-9 The present invention also proposes a construction method for external formwork of prefabricated steel structure buildings with sound-absorbing function, including the following steps:

[0059] Step 1: On-site construction material preparation, specifically including cleaning the steel structure wall, transporting the formwork body 1, and mixing to prepare a sealing colloid;

[0060] Step 2: Use hoisting equipment to hoist the formwork body 1 to the set height;

[0061] Step 3: Adjust the gaps between adjacent sections of the hoisted template body 1;

[0062] Step 4: Install temporary supports for the hoisted formwork body 1;

[0063] Step 5: Install the sealing element 16 in the groove of the template body 1 at the adjacent workstation;

[0064] Step Six: Use the locking components at the rear end of the fixed frame 11 to install the template body 1, which has been adjusted and positioned at adjacent workstations, to the steel structure wall.

[0065] Step 7: Inject the colloid for shaping and sealing;

[0066] Step 8: Repeat steps 1 to 7 to install each layer of template body 1 from bottom to top until each layer of template body 1 is installed.

[0067] This invention provides an improved prefabricated steel structure building external formwork with sound absorption function. The deformation and locking action between the concave thin iron 151 and the convex thin iron 156 in the pre-support member 15 provides gap adjustment and pre-fixation for adjacent formwork bodies 1. Then, the adjustment member 17 limits the first filling plate 176 and the second filling plate 177 for sound insulation while enclosing a space to facilitate subsequent integrated pouring. The sealing adhesive is injected into multiple sets of formwork bodies 1 through the injection holes 164 in the sealing member 16. The sealing property of the adhesive has solidified to provide integration, thereby improving the sealing effect and overall stability between multiple sets of formwork bodies 1.
