Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a roof eaves template and a supporting structure thereof. Background Art

[0002] The overhang refers to the part of the roof that protrudes from the exterior wall, and generally does not extend more than 50cm outside the building. This design is mainly to facilitate roof drainage, while also protecting the exterior wall and preventing rain from the floor joints. The design principle of the overhang takes into account the climatic conditions of different regions. For example, in the rainy southern regions, the overhang distance of the eaves is larger, while in the less rainy northern regions, the overhang distance is smaller. In addition, the overhang also has an aesthetic effect. The design and construction of the overhang can play an important role in the enclosure, erosion resistance, waterproofing, and thermal insulation of the building, especially in preventing various abnormalities that may occur after the wall is exposed to rain.

[0003] Structurally, the eaves are a type of cantilevered component. Therefore, when arranging the roof, it is necessary to deal with structural issues such as anti-overturning, drainage, and insulation at the eaves, as well as construction procedures, and make comprehensive considerations.

[0004] At present, traditional roof eaves are mainly poured by formwork. When pouring, formwork needs to be built on the roof, which will mainly encounter the following problems:

[0005] 1. After the formwork is erected, when pouring support, the free end extending outward from the building is relatively long, requiring the use of diagonal steel pipes. The diagonal steel pipes are used to support the external formwork of the overhanging eaves on the outer wall of the building. However, the inclination angle is too large, making it difficult to effectively bear the load of the overhanging part, and the supporting structure is at risk of overturning or collapse.

[0006] 2. In order to form an integral force with the building, the current cantilever formwork generally needs to be spliced ​​on the outside of the building during construction on the roof, and then the formwork is tied. Because of the high-altitude operation, the operation is difficult, and it is impossible to use excessive force or flip over to check whether the formwork is firmly locked. It is easy for the formwork to be loosely bound. Also, because of the high-altitude operation, the operation is difficult, and it is impossible to flip over and check from the side whether the formwork splicing size is accurate, resulting in low formwork assembly accuracy;

[0007] 3. Formwork binding will be affected by the difficulty of high-altitude operations, especially when pouring concrete. Since vibrating concrete is also a high-altitude operation and is tilted, the bottom of the eaves concrete extending outside the building is unsupported and the formwork is not fully supported, making it difficult for the formwork to withstand construction loads. The roof eaves gutter requires the poured concrete to be vibrated and compacted, and the formwork must be tightly spliced. Otherwise, there is a risk of formwork expansion and explosion, which in turn leads to deviations in the formed dimensions of the eaves concrete. This will cause gaps and cracks in the eaves when they solidify, increasing the risk of leakage in the eaves after solidification.

[0008] Based on this, the utility model designs a roof eaves template and a supporting structure thereof to solve the above problems. Utility Model Content

[0009] The purpose of the present invention is to provide a roof eaves template and its supporting structure, which can form a flat supporting platform through an outward-extending support rod and a horizontal frame rod, and does not use an oblique supporting structure. Instead, the outward-extending part of the eaves is forced to remain vertical, providing a more stable load-supporting bracket, which can avoid the shaking caused by the oblique support and provide greater supporting strength, thereby effectively providing a more stable supporting structure for the pouring of the eaves; and this template structure can be bound and built on the ground, and finally only needs to be placed on the top of the building. The template splicing is more convenient and the precision is higher. The left and right side surfaces and the outer templates can be conveniently checked for splicing precision, and it is more convenient to use.

An upright frame rod is fitted on the lower end of the support screw, and the support screw is inserted into the upright frame rod in a lifting manner, and the limit nut is rotatably mounted on the upper end of the upright frame rod;

[0018] The upright frame rods are vertically fixed on the building floor.

[0022] Furthermore, the bottom template is fixed on the inner wall of the outer side of the outer template, and the bottom template is tilted with the outer side higher and the inner side lower against the inner side of the outer template, and the inner and outer sides of the bottom template are respectively fixedly connected to the outer vertical flat plate and the bottom plate of the outer template, and the bottom template and the outer template are fixedly connected to form an integral structure;

[0023] The inner formwork is an integral formwork of a V-shaped structure, the inner side of the inner formwork is a vertically arranged flat plate, and the outer side of the inner formwork is an inclined flat plate with a higher outer side and a lower inner side. The outer inclined plate of the inner formwork is parallel to the inclined plate of the bottom formwork; and the inner side surface of the inner formwork is parallel to the inner vertical flat plate of the outer formwork;

[0040] See also Figures 1 to 4As shown, the utility model provides a roof eaves template and a supporting structure thereof. In order to better understand the above technical solution, the above technical solution will be described in detail below in combination with the drawings in the specification and specific implementation methods.

[0041] In a specific embodiment of the technical solution of the present utility model:

[0042] It includes a top buckle rod 1, a side pull plate 12, an outer template 2, an outward supporting rod 3 and an upright frame rod 32;

[0043] The top buckle rod 1 and the side pull plate 12 are both long straight rods. The two side pull plates 12 are arranged parallel to each other. The two side pull plates 12 are fixedly connected to form an integral structure through the top buckle rod 1. The top buckle rod 1 is connected to the top of the side pull plate 12. A top pull screw 11 is also placed between the two side pull plates 12. The top pull screw 11 penetrates the two parallel side pull plates 12. The two side pull plates 12 are connected and limited by the top pull screw 11, thereby ensuring that the positions of the two side pull plates 12 remain fixed. When the concrete is poured, the side pull plates 12 will not be deformed by the weight of the fluid on both sides, ensuring the stability of the formwork.

[0044] The outer template 2 is a U-shaped groove with an open top. The outer template 2 is an integral structure formed by assembling and fixing three flat plates. The vertical plates on the inner and outer sides of the outer template 2 are perpendicular to the bottom plate. The left and right sides of the outer template 2 are open.

[0045] A bottom template 21 and an inner template 22 are further provided inside the outer template 2. The bottom template 21 and the inner template 22 form a cavity in the shape of a building eaves inside the outer template 2.

[0046] The bottom template 21 is fixed to the inner wall of the outer side of the outer template 2. The bottom template 21 is tilted and rests against the inside of the outer template 2, with the outer side higher than the inner side. The inner and outer sides of the bottom template 21 are respectively fixedly connected to the outer vertical flat plate and the bottom plate of the outer template 2. The bottom template 21 and the outer template 2 are fixedly connected to form an integral structure.

[0047] The inner formwork 22 is a V-shaped integral formwork. The inner side of the inner formwork 22 is a vertically arranged flat plate, and the outer side of the inner formwork 22 is an inclined flat plate with a higher outer side and a lower inner side. The outer inclined plate of the inner formwork 22 is parallel to the inclined plate of the bottom formwork 21; and the inner side surface of the inner formwork 22 is parallel to the inner vertical flat plate of the outer formwork 2;

[0048] The inner template 22 does not contact the outer template 2 and the bottom template 21. The inner template 22 and the bottom template 21 form a complete cavity in the shape of the outer eaves inside the outer template 2.

[0049] The outer inclined plate of the inner template 22 is locked with the bottom template 21 by multiple mold tie rods 24, and the inner vertical plate of the inner template 22 is also locked with the inner vertical flat plate of the outer template 2 by multiple mold tie rods 24;

[0050] The mold tie rod 24 is a tension bolt, and pads 23 are provided at both ends of the mold tie rod 24. Pads 23 are provided between the tightening nut of each mold tie rod 24 and the outer template 2, the bottom template 21 and the inner template 22.

[0051] Through the splicing relationship between the inner formwork 22, the outer formwork 2 and the bottom formwork 21, such a shape forms a fixed eaves shape to adapt to the eaves structure. The concrete calibrated eaves form a drainage ditch on the roof, and the bottom is tightly connected with the building body to achieve the effect of rain protection and sealing.

[0052] The top buckle rod 1 can be detachably covered on the top of the outer template 2, and the side pull plates 12 on both sides are clamped on the outside of the vertical flat plates on the inner and outer sides of the outer template 2; the multiple top buckle rods 1 are also arranged parallel to each other, and the top buckle rods 1 and the side pull plates 12 are perpendicular to each other;

[0053] The top pull screw 11 and the top buckle rod 1 are parallel to each other, and a plurality of top pull screws 11 are provided between the two side pull plates 12. The top pull screws 11 are tension bolts;

[0054] The top-pull screw 11 is set as close as possible to the bottom of the side pull plate 12. The top-pull rod 1 and the side pull plate 12 are buckled with the outer formwork 2, and the inner and outer sides of the outer formwork 2 are limited to prevent the outer formwork 2 from flowing downward and being squeezed and deformed by the heavy pressure of concrete, ensuring that the opening at the top of the outer formwork 2 can also remain stable. The top-pull rod 1 and the side pull plate 12 increase the limiting strength of the opening of the outer formwork 2.

[0055] A plurality of cross bars 31 are fixed to the bottom of the outer formwork 2. The cross bars 31 are evenly distributed on the bottom of the outer formwork 2 along the left-right direction, and the cross bars 31 are arranged parallel to each other in the same plane.

[0056] The outward-extending support rods 3 are straight rods, and multiple outward-extending support rods 3 extend horizontally and parallel to each other outside the building. Multiple outward-extending support rods 3 are stably supported at the bottom of the cross-frame rods 31. Multiple outward-extending support rods 3 and multiple cross-frame rods 31 are locked with each other to form a criss-cross double-layer flat plate structure; a platform-type support structure is formed, which can bear a larger load more stably, and is a vertical support without the need for diagonal braces, so the support effect is better and the support is more stable. More importantly, no personnel are required to build a support structure outside, and the construction is safer.

[0057] A support screw 33 is vertically provided on the inner side of each outward supporting rod 3, and a limit nut 34 is threadedly installed on the support screw 33. An upright frame rod 32 is mounted on the lower end of the support screw 33. The support screw 33 is inserted into the upright frame rod 32 so as to be liftable, and the limit nut 34 is rotatably mounted on the upper end of the upright frame rod 32.

[0058] The vertical support rod 32 is fixed vertically on the building floor. The vertical support rod 32 is a steel pipe; the limit nut 34 is a hand-tightened nut;

[0059] The top of the support screw 33 is locked to the bottom of the inner end of the outward supporting rod 3 by a clamp. This structure allows the support screw 33 to slide vertically on the upright frame rod 32, thereby adjusting the upward support height of the support screw 33 and the support level of the outward extending portion of the outward supporting rod 3, which is convenient for adjusting the angle of the cast eaves. The construction is convenient and the adjustment is easy. It can be completed by simply rotating the limit nut 34, which further highlights the convenience of modular assembly.

[0060] It should be noted that:

[0061] 1. Because the scaffolding outside the building requires workers to move around during construction, there is a risk of movement or displacement, which will cause the eaves to be detached due to long-term vibration. Therefore, industry regulations stipulate that external wall scaffolding shall not be used as a supporting bracket for the eaves, which makes it difficult to build the eaves formwork. The protruding part outside the wall has no stable support, and the formwork can only be supported diagonally. The diagonal support rods will cause the outer end to swing under force, and there is no flat support at the bottom of the formwork, making it not light enough. This device can be assembled into a platform to support the formwork by extending the support rods and the cross rods, forming a complete flat support structure for the bottom of the formwork. It is no longer an inclined point support, but a rigid flat frame support.

[0062] 2. The existing diagonal bracing rods are only stressed at the diagonal bracing rods, and only the bracing rod points bear the load on the formwork. The stress points of the formwork are unevenly distributed, causing the concrete load to be evenly distributed by the formwork, resulting in excessive load on the formwork. However, this device uses outward-extending support rods and cross-beams to build a platform to support the formwork, forming a frame-bearing structure, which evenly distributes the stress and reduces the strength requirements of the formwork. It also makes the overall load strength of the entire support structure greater, capable of bearing concrete vibration without shaking or deflecting.

[0063] 3. The current formwork has overhangs on the roof, and the external formwork assembly is very dangerous and difficult to reach, resulting in low accuracy in formwork binding and difficulty in tight splicing. This device is spliced ​​on the ground to form a modular structure. After direct splicing is completed, the splicing accuracy is checked to ensure the overall stability on the supporting formwork platform constructed by the outward supporting rods and the cross-beams, and then locked. The construction is simple and the construction accuracy is much higher than that of the existing technology.

[0064] When the present invention is in use, the top buckle rod 1 and the side pull plate 12 themselves need to be manufactured into an integral structure to form a cover plate structure.

[0065] The inner formwork 22, outer formwork 2, and bottom formwork 21 also need to be spliced ​​on the ground. The outer formwork 2 and bottom formwork 21 are prefabricated as an integral structure, with holes opened on them as the support points for the mold tie rods 24. The entire inner formwork 22, outer formwork 2, and bottom formwork 21 are positioned and formed by the mold tie rods 24 to form an integrated formwork. Then, pads 23 are placed at each support point of the mold tie rods 24 to ensure the tension stability of the mold tie rods 24, avoid point force, and form a surface force through the pads 23 to increase the tension strength.

[0066] The upright frame rod 32, support screw rod 33 and limit nut 34 need to be assembled on the floor of the building in advance. The upright frame rod 32 is locked to the floor by anchor nails or bolts to ensure the stability of the upright frame rod 32. Then the support screw rod 33 is installed inside the upright frame rod 32, and the limit nut 34 is installed on the support screw rod 33. The limit nut 34 is installed on the top of the upright frame rod 32 to adjust the matching height of the upright frame rod 32 and the support screw 33.

[0067] Then the template of the device as a whole is assembled on the ground and placed on the top of the outward supporting rod 3, and the cross bar 31 is welded to the bottom of the outer template 2 on the ground to form an integral structure, or it can be pre-glued with adhesive or fixed into an integral structure in other ways.

[0068] Then the crossbar 31 can be placed on the top of the outward-extending support rod 3 of the floor. It is easy to install. The outward-extending support rod 3 and the crossbar 31 can be locked through a scaffolding connector or a structure similar to a hoop to form a stable structure.

[0069] Finally, the installed templates are spliced ​​in the left and right directions, such as Figure 4 As shown, the left and right sides of the outer template 2 of the template need to be tightly spliced, and the left and right ends need to be tightly fitted with the outer wall 4. If this is not enough, you can customize the left and right width of the outer template 2 and make a special one to match the width of the building.

[0070] The construction and pouring are convenient, workers do not need to work at high altitude outside the building, and the pouring and molding are fast.

[0071] The term "external" in this device refers to the end extending outside the building, while "inside" refers to the side adjacent to or within the building. "Left" and "right" refer to left and right directions along the plane of the building's exterior wall 4. The orientations and positional relationships indicated are based on those shown in the accompanying drawings and are intended solely to facilitate and simplify the description of this invention. They do not indicate or imply that the device or component referred to must have, be constructed, or operate in a specific orientation, and are therefore not to be construed as limiting this invention.

[0072] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included within the scope of protection of the claims of the present invention.
