Description

Technical Field

[0001] This utility model relates to the field of concrete engineering construction technology, and in particular to a fair-faced concrete formwork support system. Background Technology

[0002] Fair-faced concrete is a modern architectural style where, after pouring, no further painting, tiling, or stone finishing is applied; the exposed concrete surface is used directly as the finish. Fair-faced concrete formwork refers to the tools used to support the fair-faced concrete during the pouring process.

[0003] Currently, most fair-faced concrete formwork systems use either a small beam timber main beam square steel pipe system or a small beam small square steel main beam large square steel system. In practical applications, the formwork assembly relies heavily on the skill and responsibility of carpenters on-site. The quality depends on individual skill and meticulousness, making it difficult to meet the requirements of fair-faced concrete formwork systems and guarantee the flatness and appearance of the fair-faced concrete surface. Therefore, this utility model proposes a fair-faced concrete formwork support system to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fair-faced concrete formwork support system.

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

[0006] A fair-faced concrete formwork support system includes a formwork. Multiple equidistant Z-shaped steel beams are vertically fixed to the outer wall of the formwork. Multiple fixing holes are opened on the outer edges of both sides of each Z-shaped steel beam. These fixing holes are secured to one side of the outer wall of the formwork using self-tapping screws. Multiple connecting grooves are opened on the outer wall of each Z-shaped steel beam. Multiple sets of channel steel main beams are fixed to the inner wall of these connecting grooves using T-bolts. Multiple sets of connecting holes are opened on the outer wall of each channel steel main beam. Two opposing channel steel main beams are connected by multiple sets of M12 bolts, forming a double-row channel steel system. This double-row channel steel system is fixed to one side of the outer wall of the formwork using five-section tie rods.

[0007] As a further improvement of this utility model, the inner wall of the template is provided with concrete.

[0008] As a further embodiment of this utility model: the inner wall of the Z-shaped steel beam is slidably connected with a frame-shaped connector, and the outer walls of both sides of the frame-shaped connector and the Z-shaped steel beam are respectively provided with multiple side waist holes, and the frame-shaped connector and the Z-shaped steel beam are fixed by M12 bolts.

[0009] As a further improvement of this utility model: within the double-row channel steel system, an L-shaped core strip is provided on the outer wall of the opposite side of the main channel steel beam.

[0010] As a further embodiment of this utility model: the outer walls of the upper and lower sides of the L-shaped core strip are respectively provided with second limiting pin holes, the outer wall of the channel steel main beam is provided with a first limiting pin hole, and inclined pin plates are inserted into the inner walls of the second limiting pin holes and the first limiting pin holes.

[0011] As a further embodiment of this utility model: a set of inclined brackets is fixed to the outer wall of the channel steel main beam located at the corner of the wall by bolts, and an inclined tie rod is connected to the inner wall of the inclined bracket by threads.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. After the main channel steel beams and the small zigzag steel beams are fixedly connected to form a grid-shaped frame structure, the formwork can be fixed from the back of the frame structure using self-tapping screws. The formwork is fixed to one side of the small zigzag steel beams. When fixing the formwork, the principle of arranging the four corners first and then the middle is adopted, which can effectively eliminate cumulative errors. After the grid-shaped frame structure is formed, the formwork is fully laid on the corresponding platform according to the fair-faced concrete formwork drawing. Then, the formwork is hoisted and assembled using hoisting equipment to form the formwork support system. Concrete can then be poured into the formwork. Therefore, this formwork support system can be mainly applied to fair-faced concrete formwork systems, which facilitates the assembly of a large formwork system on the platform and the on-site formwork assembly by hoisting, thereby improving the efficiency and quality of fair-faced concrete wall construction.

[0014] 2. The upper and lower Z-shaped steel beams can be connected to the outer wall of the frame connector according to the height of the concrete wall. Then, the frame connector and the upper and lower Z-shaped steel beams are connected and fixed together with M12 bolts through the side waist holes on both sides of the outer wall of the Z-shaped steel beams and the frame connector. This allows the Z-shaped steel beams to adapt to different concrete wall heights, improves the applicability of the formwork support system, and avoids the loss caused by cutting the Z-shaped steel beams.

[0028] Example 1

[0029] fair-faced concrete formwork support system, such as Figure 1-8 As shown, the template includes a template 1. Multiple equidistant Z-shaped steel beams 3 are vertically fixed to the outer wall of the template 1. Multiple fixing holes 16 are opened on the outer edges of both sides of the Z-shaped steel beams 3. The fixing holes 16 are fixed to one side of the outer wall of the template 1 by self-tapping screws. Multiple connecting grooves 15 are opened on the outer wall of the Z-shaped steel beams 3. Multiple sets of channel steel main beams 2 are fixed to the inner wall of the connecting grooves 15 by T-bolts. Multiple sets of connecting holes 9 are opened on the outer wall of the channel steel main beams 2. Two opposite channel steel main beams 2 are connected by multiple sets of M12 bolts to form a double-row channel steel system. The double-row channel steel system is fixed to one side of the outer wall of the template 1 by five-section tie rods 5.

[0030] The inner wall of the template 1 is provided with concrete 8;

[0031] The inner wall of the Z-shaped steel beam 3 is slidably connected to a frame-type connector 13. The outer walls of the frame-type connector 13 and the Z-shaped steel beam 3 on both sides are respectively provided with multiple side waist holes 14. The frame-type connector 13 and the Z-shaped steel beam 3 are fixed by M12 bolts.

[0032] First, place the main channel steel beam 2 according to the fair-faced concrete formwork drawing for construction, and position it according to the center distance in the drawing. Then, place the small steel beams 3 in sequence on the main channel steel beam 2 and tighten them with M12T screws to ensure the squareness and firmness of the connection between the main channel steel beam 2 and the small steel beams 3. When connecting the main channel steel beam 2 and the small steel beams 3, clamps can be used to position the main channel steel beam 2 and the small steel beams 3, and then fix them with screws.

[0033] like Figure 1-2 As shown, after the main channel steel beam 2 and the small steel beam 3 are fixedly connected to form a grid-shaped frame structure, the template 1 can be fixed from the back of the frame structure using self-tapping screws. The template 1 is fixed to one side of the small steel beam 3. When fixing the template 1, the principle of arranging the four corners first and then the middle is adopted, which can effectively eliminate cumulative errors. After the grid-shaped frame structure is formed, the template 1 is fully laid on the corresponding platform according to the fair-faced concrete formwork drawing. Then, the template is hoisted and assembled using hoisting equipment to form a template support system. Concrete can then be poured into the interior of the template 1. Therefore, this template support system can be mainly applied to fair-faced concrete formwork systems, which facilitates the assembly of a large template system on the platform and the on-site formwork assembly by hoisting, thereby improving the efficiency and quality of fair-faced concrete wall construction.

[0034] At the same time, when fixing template 1, care should be taken to ensure that the self-tapping screws do not penetrate template 1, the joints between templates 1 should be treated with sealant, and the surface of template 1 should be kept clean to avoid scratching the surface of template 1.

[0035] Meanwhile, the upper and lower Z-shaped steel beams 3 can be connected to the outer wall of the frame connector 13 according to the height of the concrete wall. Then, the frame connector 13 and the upper and lower Z-shaped steel beams 3 are connected and fixed together with M12 bolts through the side waist holes 14 on both sides of the outer wall of the Z-shaped steel beams 3 and the frame connector 13. This allows the Z-shaped steel beams 3 to adapt to different concrete wall heights, improves the applicability of the formwork support system, and avoids the loss caused by cutting the Z-shaped steel beams 3.

[0036] The main channel steel beam 2 can be cut into standard lengths according to the fair-faced wall module, such as 3500mm (applicable to 2x1800mm wall modules). The two main channel steel beams 2 are connected in the middle with M12 bolts to form a double-row channel steel system, thereby providing stable support for the side-mounted zigzag steel beam 3 and the entire support system.

[0037] Within the double-row channel steel system, L-shaped core strips 4 are provided on the outer walls of opposite sides of the main channel steel beam 2;

[0038] The L-shaped core strip 4 has second limiting pin holes 12 on its upper and lower outer walls, and the channel steel main beam 2 has a first limiting pin hole 11 on its outer wall. The inner walls of the second limiting pin hole 12 and the first limiting pin hole 11 are fitted with inclined pin plates 6. When encountering a corner of a concrete wall, the L-shaped core strip 4 can be used to connect the channel steel main beams 2 on both sides, and the inclined pin plates 6 can be used to insert and limit the connection between the L-shaped core strip 4 and the channel steel main beam 2.

[0039] After hoisting a 3.6M unit formwork and fixing it with diagonal bracing, straight core straps can be used when hoisting adjacent unit formwork. The straight core straps are similar to the L-core straps, and are both tightened and connected by diagonal pin plates 6.

[0040] like Figure 3 As shown, a set of inclined bracing seats 7 are fixed to the outer wall of the main channel steel beam 2 located at the corner of the wall by bolts, and inclined bracing rods 10 are connected to the inner wall of the inclined bracing seats 7 by threads; the inclined bracing seats 7 and inclined bracing rods 10 can be used to fix and pull the main channel steel beam 2 located at the corner of the wall, thereby improving the support and fixing effect of the main channel steel beam 2 on the Z-shaped steel beam 3 and the formwork 1 at the corner of the wall.

[0041] Working principle: Place the main channel steel beam 2 according to the fair-faced concrete formwork drawing, and position it according to the center distance of the drawing. Then, place the small steel beams 3 on the main channel steel beam 2 in sequence and lock them with M12T screws to ensure the squareness and firmness of the connection between the main channel steel beam 2 and the small steel beams 3. When connecting the main channel steel beam 2 and the small steel beams 3, a clamp can be used to position the main channel steel beam 2 and the small steel beams 3, and then fix them with screws.

[0042] After the main channel steel beam 2 and the small steel beams 3 are fixedly connected to form a grid-shaped frame structure, the template 1 can be fixed from the back of the frame structure using self-tapping screws. The template 1 is fixed to one side of the small steel beams 3. When fixing the template 1, the principle of arranging the four corners first and then the middle is adopted, which can effectively eliminate cumulative errors. After the grid-shaped frame structure is formed, the template 1 is fully laid on the corresponding platform according to the fair-faced concrete formwork drawing. Then, the template is hoisted and assembled using hoisting equipment to form a template support system. Concrete can then be poured into the interior of the template 1.

[0043] The upper and lower Z-shaped steel beams 3 can be connected to the outer wall of the frame connector 13 according to the height of the concrete wall. Then, the frame connector 13 and the upper and lower Z-shaped steel beams 3 are connected and fixed together by M12 bolts through the side waist holes 14 on both sides of the outer wall of the frame connector 13 and the Z-shaped steel beams 3.

[0044] 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.
