Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a support device for the construction of double-layer walls and its construction method. Background Technology

[0002] During building construction, sometimes sloping walls are encountered, with an upper structural wall above them, forming a double-layered wall structure, such as certain wind tunnel or chimney structures. Construction of such double-layered walls presents several difficulties: firstly, installing and securing the formwork for the sloping wall is challenging; secondly, the lower sloping wall obstructs the upper structural wall, hindering the proper erection of its formwork. Currently, the sloping wall or upper structural wall is typically poured and solidified before the other layer can be poured. This method results in slow construction progress, and the existing support structure cannot adequately support the formwork of both layers simultaneously, leading to poor overall structural integrity.

[0003] Therefore, it is necessary to provide a support device and construction method for double-wall construction, which should improve construction efficiency, ensure structural reliability, and enhance construction safety. Summary of the Invention

[0004] In view of this, one of the objectives of the present invention is to provide a support device for the construction of double-layer walls, which has good integrity, reliable structure, and is easy to install, thereby improving construction efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a support device for double-layer wall construction, comprising a support frame body, an upper support member, and multiple sets of connecting components disposed on the support frame body. The double-layer wall includes an inclined wall and an upper wall located above the inclined wall. The multiple sets of connecting components are used to connect the inclined wall template to the support frame body. Each connecting component includes a connecting rod, a lower support plate, and an upper support plate. The connecting rod is vertically arranged and penetrates downward through the lower template of the inclined wall before being fixedly connected to the support frame body. The lower support plate is fixedly connected to the lower part of the connecting rod to support the lower template of the inclined wall, and the upper support plate is fixedly connected to the upper part of the connecting rod to support the upper template of the inclined wall. The connecting rod penetrates upward through the upper template of the inclined wall before being fixedly connected to the upper support member, which is used to support the upper structural wall template.

[0006] Furthermore, the support frame body includes a support rod supported on the ground, and the lower end of the connecting rod is threadedly connected to the top of the support rod.

[0007] Furthermore, a lower stop plate is fixedly connected to the lower part of the connecting rod, and the lower stop plate abuts against the upper end face of the support rod.

[0008] Furthermore, a lower reinforcing beam is fixedly connected to the lower formwork, and an upper reinforcing beam is fixedly connected to the upper formwork; the lower and upper reinforcing beams are arranged parallel to each other along the inclination direction of the inclined wall, and are arranged in multiples at intervals along the transverse direction of the inclined wall.

[0009] Furthermore, the support frame body also includes a horizontal brace, which is horizontally arranged and fixedly connected to the support rod; and the horizontal brace is supported below the lower reinforcing beam.

[0010] Furthermore, the connecting rod includes a lower section rod, an upper section rod, and a connecting sleeve, with the lower section rod and the upper section rod respectively threaded to both ends of the connecting sleeve.

[0011] Furthermore, the upper section rod extends upward and penetrates the upper template, and an upper stop plate is fixedly connected to the upper end of the upper section rod. The upper stop plate is used to provide a support point for the upper support member.

[0012] Another object of the present invention is to provide a method for constructing a double-layer wall, which uses the support device described above and includes the following steps:

[0013] S1: Erection of the support frame body;

[0014] S2: Install the lower section rod and lower support plate on the top of the support rod of the support frame body;

[0015] S3: Lay the lower template, then install the connecting sleeve, and then lay the upper section rod and upper support plate;

[0016] S4: Install the support components, and then lay the formwork for the upper wall;

[0017] S5: Pouring, simultaneously completing the pouring of the sloping wall and the upper wall;

[0018] S6: Demolding.

[0019] Furthermore, the lower section rod and the lower support plate are an integral structure; the upper section rod and the upper support plate are an integral structure.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The inclined wall formwork support device provided by this invention integrates the upper support component, the connecting assembly, and the heat exchange support frame body into a single unit, resulting in good overall integrity, structural stability, and simplified formwork installation. The connecting rod is vertically positioned and penetrates downwards through the lower formwork of the inclined wall before being fixedly connected to the support frame body, providing excellent vertical support for the inclined wall formwork. This helps resist the impact of poured concrete and the self-weight of the concrete, improving structural strength and thus enhancing safety. Simultaneously, the upper and lower support plates on the connecting rod provide support mounting points for the upper and lower formwork of the inclined wall, facilitating their fixing. For example, the upper and lower formwork can be directly fixed to the corresponding upper and lower support plates using rivets, further simplifying the installation of the inclined wall formwork. In addition, the upper and lower support plates also help to create a water-stopping effect at the through-holes of the connection nodes, reducing leakage and improving the quality of wall formation.

[0022] 2. The double-layer wall construction method provided by this invention can complete the simultaneous construction of the sloping wall and the upper wall, saving the time required for the concrete to solidify after pouring the first layer separately, and greatly improving construction efficiency.

[0023] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0027] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only for illustrating the basic concept of the present invention; in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] Please see Figure 1-2 A support device for constructing a double-layer wall includes a support frame body 1, an upper support member 6, and multiple sets of connecting components 2 disposed on the support frame body 1. The double-layer wall includes an inclined wall 3 and an upper wall 7 located above the inclined wall 3. The multiple sets of connecting components 2 are used to connect the template of the inclined wall 3 to the support frame body 1. Here, the support frame body 1 is generally a scaffold and is located below the inclined wall 3. The connecting components 2 include a connecting rod 20, a lower support plate 21, and an upper support plate 22. The connecting rod 20 is vertically arranged and penetrates downward through the lower template 302 of the inclined wall 3 before being fixedly connected to the support frame body 1, such as by welding or screwing. The lower support plate 21 is fixedly connected to the lower part of the connecting rod 20 to support the lower template 302 of the inclined wall 3. In practice, the lower support plate 21 and the lower template 302 can be fixedly connected by rivets, etc. The upper support plate 22 is fixedly connected to the upper part of the connecting rod 20 to support the upper template 301 of the inclined wall 3. In practice, the upper support plate 22 and the upper template 301 can be fixedly connected by rivets, etc. The connecting rod 2 passes upward through the upper template 301 of the inclined wall 3 and is then fixedly connected to the upper support member 6. The upper support member 6 is used to support the template of the upper wall 7.

[0029] In this structural design, the upper support member 6 and the heat exchange support frame body 1 of the connecting component 2 are connected as a whole; the connecting rod 20 is vertically set and passes through the lower template 302 of the inclined wall 3 before being fixedly connected to the support frame body 1, which can provide good vertical support for the inclined wall template, which is conducive to resisting the impact force of poured concrete and the self-weight of concrete, improving structural strength, and thus improving safety; at the same time, the upper support plate 22 and the lower support plate 21 set on the connecting rod 20 can provide support installation points for the upper template 301 and the lower template 302 of the inclined wall, which is conducive to completing the fixing of the upper template 301 and the lower template 302 of the inclined wall. For example, the upper template 301 and the lower template 302 can be directly fixedly connected to the upper support plate 22 and the lower support plate 21 by rivets, which simplifies the installation of the inclined wall template; in addition, the upper support plate 21 and the lower support plate 22 can also help to form a water-stopping effect at the through holes of the connection nodes, reduce leakage, and thus improve the quality of wall forming.

[0030] In this embodiment, the support frame body 1 includes a support rod 101 supported on the ground, and the lower end of the connecting rod 20 is threadedly connected to the top of the support rod 101. Specifically, an internal thread is provided at the top of the support rod 101, and an external thread is provided at the corresponding end of the connecting rod 20. This structural design facilitates the quick connection between the connecting rod 20 and the support frame body 1 through the threaded connection.

[0031] Of course, the support rod 101 here is generally part of the scaffolding, and multiple connecting components 2 are set at certain intervals during the erection of the scaffolding.

[0032] In this embodiment, a lower stop plate 20c-1 is fixedly connected to the lower part of the connecting rod 20, such as by welding, and the lower stop plate 20c-1 abuts against the upper end face of the support rod 101; specifically, the lower stop plate 20c-1 is generally circular; in this structural design, by adding the lower stop plate 20c-1, the connecting rod 20 can be ensured to be connected in place, and the vertical bearing capacity can be improved to ensure the structural strength.

[0033] In this embodiment, a lower reinforcing beam 4 is fixedly connected to the lower template 302, such as by screws; an upper reinforcing beam 5 is fixedly connected to the upper template 301, such as by screws. In practice, the lower reinforcing beam 4 and the upper reinforcing beam 5 are generally made of timber. The lower reinforcing beam 4 and the upper reinforcing beam 5 are arranged parallel to each other along the inclination direction of the inclined wall, and multiple beams are set at intervals along the transverse direction of the inclined wall 3. In this structural design, by setting the lower reinforcing beam 4 and the upper reinforcing beam 5, the stability of the inclined wall template can be improved and the forming quality can be guaranteed.

[0034] In this embodiment, the support frame body 1 also includes a horizontal support rod 102, which is horizontally arranged and fixedly connected to the support rod 101. Generally, the horizontal support rod 102 is welded to multiple support rods 101 along its own length direction or connected by a locking buckle or other means. The horizontal support rod 102 is supported below the lower reinforcing beam 4. In this structural design, by adding a horizontal support rod 102 below the lower reinforcing beam 4, the support and bearing strength of the inclined wall formwork can be improved. At the same time, the combination of multiple lower reinforcing beams 4 can form a crisscross structure, which can improve the structural strength of the lower formwork 302 and thus improve the casting quality.

[0035] In this embodiment, the connecting rod 20 includes a lower section rod 20c, an upper section rod 20a, and a connecting sleeve 20b. The lower section rod 20c and the upper section rod 20a are respectively threaded to the two ends of the connecting sleeve 20b. This structural design allows for adjustment of the distance between the upper template 301 and the lower template 302 by adjusting the connecting sleeve 20b, thus meeting the spacing requirements of different specifications. It also facilitates the assembly of the overall structure. Specifically, the lower support plate 21 and the lower section rod 20c can be prefabricated as a whole, and the upper support plate 22 and the upper section rod 20a can also be assembled as a whole. During installation, the lower support plate 21 and the lower section rod 20c can be assembled first, then the lower template 302 can be installed, followed by the connecting sleeve 20b; then the upper template 301 can be installed, and finally the upper support plate 22 and the upper section rod 20a can be installed.

[0036] In this embodiment, the upper section rod 20a extends upward and penetrates the upper template 301, and an upper stop plate 20a-1 is fixedly connected to the upper end of the upper section rod 20a. The upper stop plate 20a-1 is used to provide a support point for the upper support member 6. Specifically, an external thread is designed at the upper end of the upper section rod 20a, and an upper support member 6 is threadedly connected to the upper end of the upper section rod 20a. The upper support member 6 completes the support for the template of the upper wall 7. The support member 6 is generally a rod-shaped structure. The template support of the upper wall 7 is completed by setting a support plate at the top of the rod. Here, the template laying of the upper wall can refer to the template laying of the flat floor slab, which is the prior art and will not be described in detail here. Through the through structure, the support for the inclined wall 3 and the template of the upper wall 7 can be completed at the same time, and the overall integrity is strong.

[0037] A method for constructing a double-layer wall, using the aforementioned support device, includes the following steps:

[0038] S1: Erection of the support frame body;

[0039] S2: Install the lower section rod and lower support plate on the top of the support rod of the support frame body;

[0040] S3: Lay the lower template, then install the connecting sleeve, and then lay the upper section rod and upper support plate;

[0041] S4: Install the support components, and then lay the formwork for the upper wall;

[0042] S5: Pouring, simultaneously completing the pouring of the sloping wall and the upper wall;

[0043] S6: Demolding;

[0044] This double-layer wall construction method allows for the simultaneous construction of the sloping wall and the upper wall, eliminating the need for separate concrete curing time after pouring the first layer, and greatly improving construction efficiency.

[0045] In this embodiment, the lower section rod 20c and the lower support plate 21 are an integral structure; the upper section rod 20a and the upper support plate 22 are an integral structure, which are generally prefabricated and can be assembled on site, further improving construction efficiency.

[0046] Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
