Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to an exterior wall eaves template and a template supporting method. Background Art

[0002] A building formwork is a temporary support structure, manufactured according to design requirements, that helps concrete structures and components form to the specified positions and dimensions, maintain their correct position, and withstand the formwork's own weight and external loads. The purpose of formwork engineering is to ensure the quality and safety of concrete projects, accelerate construction progress, and reduce costs.

[0003] During the concrete construction of the building's exterior walls, the formwork used for the structural cantilever is prone to dripping at the corners due to the joints between adjacent panels, which requires subsequent wall cleaning. The exterior facade construction is difficult, time-consuming, and labor-intensive. In addition, the dripping causes concrete to be mixed in the joints, making it difficult to remove the formwork at the bottom of the cantilever, and the ends are easily damaged, reducing the turnover efficiency of the formwork. Summary of the Invention

[0004] One of the purposes of the present invention is to provide an exterior wall eaves template, which can protect the joints and the end faces of the template, avoid dripping and enhance the turnover of the template.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] An exterior wall eaves formwork includes a first formwork, a second formwork and a shielding member. The first end face of the second formwork abuts the first end of the first formwork to form a joint. The shielding member is arranged at the positive corner of the combination of the first formwork and the second formwork. The shielding member abuts the first formwork and the second formwork and is configured to cover the joint and the first end face of the first formwork.

[0007] Optionally, the shielding member is a groove-shaped structure, and the two sides of the groove width can respectively abut against the first template and the second template to form a covering space, and the covering space sets the first end face of the first template and the joint cover therein.

[0008] Optionally, the shielding member is a hollow arc-shaped tube.

[0009] Optionally, the shielding member is formed by cutting a PVC pipe along its axial direction.

[0010] Optionally, the diameter of the shielding member is 16 mm.

[0011] Optionally, a connecting piece is further included, and the shielding piece is fixedly connected to the first template or the second template via the connecting piece.

[0012] Optionally, the connecting member is an iron nail, and a plurality of the iron nails are arranged at intervals along the length direction of the shielding member.

[0013] Another object of the present invention is to provide a formwork support method for supporting the above-mentioned exterior wall eaves formwork, which specifically includes the following steps:

[0014] S1. Setting up a template at the designed eaves position, the template comprising a first template and a second template, wherein a first end surface of the first template is flush with a bottom surface of the eaves, and the second template abuts against the first template to form the joint;

[0015] S2. Supporting the first template and the second template using a supporting structure;

[0016] S3. Installing the shielding member: Fixing the shielding member to the first end surface of the first template or the supporting surface of the second template so that the shielding member spans the joint and completely covers the first end surface of the first template;

[0017] S4, steel bar binding and concrete pouring;

[0018] S5. The formwork is removed and the exterior wall eaves are formed.

[0019] Optionally, the method further includes processing a shielding piece, wherein the shielding piece is formed by cutting the PVC wire tube along its axial direction.

[0020] Optionally, in step S5, the second template is removed first, and then the first template is removed.

[0021] The beneficial effects of the present invention are as follows: the exterior wall cantilevered eaves formwork and formwork support method of the present invention utilize a shielding member to shield the first end face of the first formwork and the joint between the first formwork and the second formwork, which can not only solve the common quality problem of exterior wall concrete dripping, reduce the probability of later external structural construction due to dripping treatment, ensure construction safety, but also avoid damage to the end faces of the first formwork and the second formwork, enhance formwork turnover, reduce material waste, and save costs.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0029] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0030] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., referring to positions or locations, are based on the positions or locations shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation.

[0032] Existing exterior wall eaves formwork generally includes a first formwork that limits the structural wall and a second formwork that limits the eaves. When supporting, the first formwork is first supported so that its top end face is flush with the designed eaves bottom. Then, one end face of the second formwork is abutted against the first formwork, and the upper surface of the second formwork is flush with the eaves bottom. The first formwork and the second formwork are supported by a supporting structure to ensure that the exterior wall eaves formwork structure is firmly combined. Then, the steel bars are tied and the concrete is poured. When the end face of the second formwork abuts against the first formwork, a joint will be generated. If the joint is too large, it will cause dripping problems. This embodiment improves and optimizes the traditional exterior wall eaves formwork based on its form, and proposes an exterior wall eaves formwork that can prevent dripping and is reusable.

[0033] refer to Figure 1 As shown, the exterior wall eaves template proposed in this embodiment includes a first template 1, a second template 2 and a shielding member 3. The first template 1 and the second template 2 are both plate-like structures, and can be made of either wood material or a new type of template that "replaces wood with steel". The first end face of the second template 2 abuts the first end of the first template 1 to form a joint a. The shielding member 3 is arranged at the positive corner of the combination of the first template 1 and the second template 2 (the side facing the eaves 6, the side of the second template 2 facing the eaves 6 is the supporting surface), and its length is the same as the length of the joint a. The shielding member 3 can abut against the first template 1 and the second template 2, and is configured to cover the joint a and the first end face of the first template 1.

[0034] In this embodiment, the setting of the shielding member 3 can prevent concrete from flowing out from the joint a and causing dripping, thereby reducing the cost of treating dripping on the exterior wall; at the same time, when the second formwork 2 is removed, since there is no concrete at the joint a, the end face of the second formwork 2 is not adhered to the first formwork 1, which can reduce damage to the end face of the second formwork 2, and the first formwork 1 is not adhered to the concrete pouring surface, which can reduce damage to the end face of the first formwork 1, thereby achieving reuse and reducing costs.

[0035] It is understood that, generally speaking, the overhang 6 is perpendicular to the structural wall 5, but this does not rule out the possibility that the overhang 6 is not perpendicular to the structural wall 5. During construction, the first formwork 1 and the second formwork 2 are not necessarily perpendicular. Instead, the first formwork 1 is parallel to the structural wall 5, and the second formwork 2 is parallel to the lower surface of the overhang 6, so as to limit the position of the structural wall 5 and the overhang 6, respectively, and at the same time, the first end surface of the second formwork 2 can abut against the first formwork 1 to form a joint a.

[0036] Sometimes, due to construction errors, the first end face of the first template 1 and the supporting surface of the second template 2 are not in the same plane. In order to avoid this situation affecting the covering effect of the shielding member 3 on the joint a and the end face of the first template 1, the shielding member 3 is a groove-shaped structure. The two sides of the groove width can respectively abut against the first template 1 and the second template 2 and form a covering space at the positive corner. The covering space covers the first end face of the first template 1 and the joint a. Exemplarily, the shielding member 3 can use a hollow circular arc tube, and the covering space is arc-shaped. Specifically, the shielding member 3 can be made of a wire tube, such as a PVC wire tube, cut along its axial direction, which is low in cost. In other embodiments, the shielding member 3 can also use a rectangular groove tube. In this case, the shielding member 3 is cut from a square tube along its length.

[0037] The diameter of the conduit can be adjusted according to the thickness of the formwork. In this embodiment, since the commonly used formwork thickness is approximately 12 mm, a 16 mm diameter PVC conduit is selected. This conduit is axially divided into two halves. This ensures complete coverage of the first end face of the first formwork 1 and the joint a, while also preventing the conduit from being too large and affecting the appearance of the overhanging eaves during concrete pouring. At this point, the conduit is connected to the first formwork 1.

[0038] To secure the shielding member 3 relative to the first and second templates 1 and 2, the shielding member 3 is secured to the first and second templates 1 and 2 via connectors 4, which can be constructed using nails or bolts. In this embodiment, to improve construction efficiency, the connectors 4 are constructed using nails that penetrate the shielding member 3 and are inserted into the first and second templates 1 and 2. Multiple nails are provided, spaced approximately 1 meter apart along the length of the shielding member 3. This ensures a stable connection between the shielding member 3 and the first and second templates 1 and 2, preventing the shielding member 3 from tilting and losing its shielding effect.

[0039] This embodiment takes the overhanging eaves 6 as an example and perpendicular to the structural wall 5, and further proposes a method for supporting the above-mentioned overhanging eaves template for the exterior wall, which specifically includes the following steps:

[0040] S1. Install a template below the designed overhanging eaves 6 to form a joint a. The template includes a first template 1 and a second template 2. The first template 1 is installed vertically, with its first end surface as flush as possible with the bottom plane of the overhanging eaves 6. The second template 2 is installed perpendicular to the first template 1, with its first end surface abutting the first end of the first template 1, and the supporting surface of the second template 2 flush with the bottom plane of the overhanging eaves 6.

[0041] S2. Use a supporting structure to support the first template 1 and the second template 2.

[0042] S3. Install shielding member 3: Use nails to secure shielding member 3 to the first end face of first form 1. Shielding member 3 spans joint a formed between first and second form 1, 2, and completely covers the first end face of first form 1. This shields joint a and the first end face of first form 1, preventing them from contacting and sticking to the concrete during subsequent concrete construction. The nails should be spaced 1 meter apart along the length of shielding member 3.

[0043] S4. After the shielding member 3 is installed, the steel bars are tied and the concrete is poured.

[0044] S5. Formwork Removal and Forming of Exterior Wall Overhang 6: It should be noted that because shielding member 3 is embedded in overhang 6 after concrete pouring, second formwork 2 must be removed first to provide clearance for removal of first formwork 1. Then, first formwork 1 is removed in an obliquely downward direction. At this point, shielding member 3 is removed along with first formwork 1. Because shielding member 3 is present, joint a and the first end face of first formwork 1 are not adhered to the concrete, preventing damage to the formwork.

[0045] In addition to the above steps, the method for supporting the exterior wall eaves formwork in this embodiment also includes:

[0046] To process the shielding member 3 , a PVC wire pipe with a diameter of 16 mm (when the first template 1 and the second template 2 are thicker, the size of the wire pipe can be adjusted) can be cut into two halves along its axial direction, with one half serving as the shielding member 3 .

[0047] It is understandable that this step can be completed before the formwork is erected, or it can be completed after the formwork is erected. To improve construction efficiency, in this embodiment, the shielding member 3 has been processed before the formwork is erected.

[0048] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
