Description

Technical Field

[0001] This application relates to the field of building construction, and more specifically, to a support formwork for a small, semi-enclosed building structure and a method for its removal. Background Technology

[0002] With the continuous development of urbanization in my country, the types of urban architectural styles have become more diverse. Some architectural styles have formed narrow, semi-enclosed space structures, such as bay window structures, which resemble narrow, semi-enclosed spaces.

[0003] In the current construction of small, semi-enclosed building structures, due to the small openings, workers mostly use traditional wooden formwork to erect the formwork inside the confined space and then fix it to the outer formwork using tie bolts. However, the drilling method for tie bolts affects the insulation effect inside the concrete structure, and the need to clean the tie bolt holes later increases the cost of secondary labor. Furthermore, after the concrete construction of the small, semi-enclosed building structure is completed, the limited space makes it impossible for construction personnel to enter and remove the internal formwork, affecting the building's usability. In addition, the formwork materials cannot be reused, increasing construction costs.

[0004] Therefore, there is a need for a building formwork support template and dismantling construction method suitable for demolding in narrow, semi-enclosed spaces to meet the usage requirements. Summary of the Invention

[0005] The purpose of this application is to provide a support formwork for a narrow, semi-enclosed building and a method for its removal. This method allows construction workers to easily remove the formwork from the narrow, semi-enclosed space, facilitates the recycling of the formwork to improve economic efficiency, and avoids the use of tie rods to support the formwork.

[0006] This application is implemented as follows:

[0007] This application provides a support formwork for a narrow, semi-enclosed building structure, comprising an inner upper formwork, an inner lower formwork hinged at the bottom of the inner upper formwork, a top formwork hinged at the top of the inner upper formwork on one side, a bottom formwork hinged at the bottom of the inner lower formwork on one side, two end formworks, an outer upper formwork, an outer lower formwork, and at least one support rod, one end of which is connected to the hinge joint between the inner upper formwork and the inner lower formwork.

[0008] In some alternative implementations, the top template is connected to at least one upper reserved pull rope, the bottom template is connected to at least one lower reserved pull rope, and the support rod is provided with at least two limiting rings, with the upper and lower reserved pull ropes passing through at least one limiting ring respectively.

[0009] In some alternative implementations, the top template is hinged with at least one top rod, the bottom of which is detachably connected to a support rod.

[0010] In some alternative embodiments, the top of at least one end template is hinged to one end of the top template.

[0011] In some alternative implementations, the bottom of at least one end template is hinged to one end of the bottom template.

[0012] In some alternative implementations, the two end templates are hinged to one end of the top template and the bottom template, respectively.

[0013] In some alternative embodiments, at least one end template includes an upper end template hinged to one end of a top template and a lower end template hinged to one end of a bottom template.

[0014] In some alternative implementations, the upper end dividing template and the lower end dividing template are each provided with at least one buckle, and the top template and the bottom template are each provided with a retaining seat. When the upper end dividing template and the lower end dividing template are rotated to fit against the top template and the bottom template, the buckle is detachably connected to the corresponding retaining seat.

[0015] This application also provides a method for dismantling the supporting formwork of the aforementioned narrow, semi-enclosed building structure, which includes the following steps:

[0016] Remove the two outer upper and lower formwork panels that are attached to the upper and lower sides of the outer wall of the narrow semi-enclosed space;

[0017] Remove the two end formwork panels that were attached to the end walls of the narrow, semi-enclosed space;

[0018] Pull the support rod outward from the narrow semi-enclosed space, causing the support rod to move the hinge joint of the upper inner template and the lower inner template outward, and causing the upper inner template and the lower inner template to fold into a V shape and move outward. The upper inner template and the lower inner template also cause the top template and the bottom template to fold into an M-shaped structure and detach from the inner wall of the narrow semi-enclosed space.

[0019] Continue pulling the support rod outward to cause the folded upper inner template, lower inner template, top template, and bottom template to detach from the narrow semi-enclosed space.

[0020] In some optional implementations, when the support rod is pulled outward to fold the inner upper template and inner lower template into a V-shape and move outward, the upper reserved pull rope connected to the top template and the lower reserved pull rope connected to the bottom template are pulled simultaneously. The upper and lower reserved pull ropes pass through the limiting rings on the support rod and move outward, causing the top template and bottom template to fold into an M-shaped structure and detach from the inner wall of the narrow semi-enclosed space. The support rod, upper reserved pull rope and lower reserved pull rope are pulled outward further, so that the folded inner upper template, inner lower template, top template and bottom template detach from the narrow semi-enclosed space.

[0021] The beneficial effects of this application are as follows: The supporting formwork for a narrow, semi-enclosed building structure provided by this application includes an inner upper formwork, an inner lower formwork hinged to the bottom of the inner upper formwork at its top, a top formwork hinged to the top of the inner upper formwork on one side, a bottom formwork hinged to the bottom of the inner lower formwork on one side, two end formworks, an outer upper formwork, an outer lower formwork, and at least one support rod, one end of which is connected to the hinge joint between the inner upper formwork and the inner lower formwork. The supporting formwork and dismantling method for a narrow, semi-enclosed building structure provided by this application can cause the inner upper formwork and the inner lower formwork to fold into a V-shape and move outward by stretching the support rod. Furthermore, the inner upper formwork and the inner lower formwork can cause the top formwork and the bottom formwork to fold into an M-shaped structure and detach from the narrow, semi-enclosed space. This facilitates the recycling of the formwork, improving economic efficiency, and avoids the use of tie rods to support the formwork. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] The features and performance of the support template and dismantling method for small, semi-enclosed building structures of this application are further described in detail below with reference to embodiments.

[0036] like Figure 1 and Figure 2As shown, this application embodiment provides a support template for a small, semi-enclosed building structure, used for formwork and pouring operations on a semi-enclosed concrete structure 310 that encloses a small space 300. One side of the semi-enclosed concrete structure 310 has an opening 320 communicating with the small space 300. The semi-enclosed concrete structure 310 contains insulation material layers 330 located above and below the opening 320. The support template for the small, semi-enclosed building structure includes components that fit within the small space 300. The upper inner template 100 of the upper part of the wall, the lower inner template 110 attached to the lower part of the inner wall of the narrow space 300, the top template 120 attached to the top wall of the narrow space 300, the bottom template 130 attached to the bottom wall of the narrow space 300, the two end templates 140 respectively attached to the inner walls at both ends of the narrow space 300, the upper outer template 150 attached to the inner wall above the opening 320 of the narrow space 300, and the lower outer template 150 attached to the inner wall below the opening 320 of the narrow space 300. The formwork 160 and a support rod 170 are provided. The top of the inner lower formwork 110 is hinged to the bottom of the inner upper formwork 100. One side of the top formwork 120 is hinged to the top of the inner upper formwork 100. One side of the bottom formwork 130 is hinged to the bottom of the inner lower formwork 110. One end of the support rod 170 is connected to the hinge point between the inner upper formwork 100 and the inner lower formwork 110, and the other end extends out of the opening 320 of the narrow space 300. The top formwork 120 is located away from the inner upper formwork 100. A pre-reserved upper pull rope 180 is connected to the bottom surface of the bottom template 130, away from the inner lower template 110, and a pre-reserved lower pull rope 190 is connected to the top surface of the bottom template 130. The support rod 170 is provided with two limiting rings 200. The pre-reserved upper pull rope 180 and the pre-reserved lower pull rope 190 respectively pass through a limiting ring 200 and extend out of the opening 320 of the narrow space 300. A top rod 210 is hinged to the bottom surface of the top template 120. The bottom of the top rod 210 is detachably connected to the support rod 170 by bolts.

[0037] When constructing a semi-enclosed concrete structure 310 to enclose a narrow space 300 using the formwork of the supporting template for the narrow semi-enclosed building provided in this embodiment, the internal reinforcement of the semi-enclosed concrete structure 310 is constructed first, followed by the construction of the supporting template for the narrow semi-enclosed building. First, the folded inner upper template 100, inner lower template 110, top template 120, and bottom template 130 are pushed into the narrow space 300 through the opening 320 using support rods 170, so that the bottom template 130 fits against the bottom wall of the narrow space 300. Then, the support rods 170 and top rods 210 are pushed to unfold the inner upper template 100 and inner lower template 110 respectively. The top and bottom parts of the inner wall of the narrow space 300 are fitted together, and the top template 120 is fitted together with the top wall of the narrow space 300. The bottom of the top rod 210 is connected to the support rod 170 by bolts to stably support the top template 120. Then, the two end templates 140 are moved into the narrow space 300 through the opening 320 and installed at both ends. Next, the outer upper template 150 and the outer lower template 160 are installed above and below the opening 320, respectively. The steel reinforcement of the top of the semi-enclosed concrete structure 310 is constructed. Then, the outer wall template 230 of the outer wall of the semi-enclosed concrete structure 310 is constructed, and the concrete pouring construction can be carried out to obtain the semi-enclosed concrete structure 310.

[0038] The supporting template for a narrow, semi-enclosed building structure provided in this embodiment hinges the inner upper template 100, inner lower template 110, top template 120, and bottom template 130 together so that they can be folded and inserted into the narrow space 300 through the opening 320. One end of the support rod 170 is connected to the hinge joint between the inner upper template 100 and the inner lower template 110. A top rod 210 is hinged to the bottom surface of the top template 120, which allows workers to easily push the support rod 170 and the top rod 210 to unfold the folded inner upper template 100, inner lower template 110, top template 120, and bottom template 130 to fit against the inner wall of the narrow space 300. The top rod 210 is used to press and support the upper inner template 100 and the lower inner template 110, and the top template 120 is also pressed and supported by the top rod 210, thus forming a template support system in a narrow semi-enclosed space to achieve a one-time molding effect. This reduces construction steps, protects construction safety, and eliminates the traditional process of drilling holes for tie bolts on the inner and outer templates. It also protects the insulation effect of the built-in insulation of the semi-enclosed concrete structure 310. In addition, when workers cannot enter the narrow semi-enclosed space 300, the template can be remotely and quickly installed and folded and dismantled outside the opening 320, which is convenient for recycling and reuse after the template is dismantled, avoiding material waste and saving costs.

[0039] In other alternative embodiments, the tops of one or two end templates 140 may also be hinged to one end of the top template 120. The end template 140 can be rotated to fit against the top template 120, folded, moved through the opening 320 into the narrow space 300, and then rotated in the opposite direction to fit against the inner wall of the end of the narrow space 300.

[0040] In other alternative embodiments, the bottom of one or two end templates 140 may also be hinged to one end of the bottom template 130. The end template 140 can be rotated to fit the bottom template 130, folded, moved through the opening 320 to the narrow space 300, and then rotated in the opposite direction to fit the inner wall of the end of the narrow space 300.

[0041] In other alternative embodiments, the two end templates 140 may also be hinged to one end of the top template 120 and the bottom template 130, respectively. The two end templates 140 may be rotated to fit the top template 120 and the bottom template 130, folded, moved through the opening 320 to the narrow space 300, and then rotated in the opposite direction to fit the inner wall of the end of the narrow space 300.

[0042] In other alternative embodiments, such as Figure 3 As shown, one or two end templates 140 may also include an upper end template 141 that is hinged to one end of the top template 120 and a lower end template 142 that is hinged to one end of the bottom template 130. Thus, the upper end template 141 and the lower end template 142 can be rotated to fit the top template 120 and the bottom template 130 respectively. After folding, the templates 141 and 142 can be moved through the opening 320 to the narrow space 300 and then rotated in the opposite direction to fit the inner wall of the end of the narrow space 300.

[0043] In other alternative embodiments, such as Figure 4 As shown, the upper end template 141 and the lower end template 142 are each provided with a buckle 143, and the buckle 143 is provided with a threaded hole. The bottom surface of the top template 120 and the top surface of the bottom template 130 are respectively provided with a mounting base 220, and the mounting base 220 is provided with a threaded hole. The upper end template 141 and the lower end template 142 are respectively provided with a slot 144 for engaging the buckle 143 on the corresponding lower end template 142 and the upper end template 141. When the upper end template 141 and the lower end template 142 are rotated to fit against the top template 120 and the bottom template 130, the threaded hole of the buckle 143 is aligned with the threaded hole of the corresponding mounting base 220 and then connected by bolts. This facilitates fixing the position of the upper end template 141 and the lower end template 142 so that they can be unfolded and installed on the inner wall of the narrow space 300 after passing through the opening 320.

[0044] like Figure 1 and Figure 2As shown in the embodiment of this application, a method for dismantling the above-mentioned support formwork for a narrow, semi-enclosed building structure is also provided, which includes the following steps:

[0045] Step 1: Remove the outer wall formwork 230 from the outer side of the semi-enclosed concrete structure 310.

[0046] Step 2: Remove the upper outer template 150 and lower outer template 160 of the inner wall above and below the opening 320 of the narrow space 300.

[0047] Step 3: Remove the two end templates 140 that are attached to the end walls at both ends of the narrow space 300;

[0048] Step 4: Separate the bottom of the top rod 210 from the support rod 170, and pull the support rod 170 outward from the opening 320. This causes the support rod 170 to move the hinge of the inner upper template 100 and the inner lower template 110 outward. At the same time, it causes the inner upper template 100 and the inner lower template 110 to rotate and fold towards each other to form a V-shape. The inner upper template 100 and the inner lower template 110 also cause the top template 120 to descend and the bottom template 130 to rise and fold to form an M-shaped structure that detaches from the inner wall of the narrow space 300.

[0049] Step 5: While continuing to pull the support rod 170 outward, pull the upper reserved pull rope 180 connected to the top template 120 and the lower reserved pull rope 190 connected to the bottom template 130, so that the folded M-shaped inner upper template 100, inner lower template 110, top template 120 and bottom template 130 are lifted and released from the semi-enclosed narrow space 300 through the opening 320.

[0050] In other alternative embodiments, the top of one or two end templates 140 can also be hinged to one end of the top template 120. In this case, when removing the two end templates 140 that are attached to the two end walls of the narrow space 300 in step three, the end template 140 that is hinged to one end of the top template 120 can be rotated to fit the bottom surface of the top template 120 and then fixed with steel bars. Subsequently, along with the inner upper template 100 and the inner lower template 110, the top template 120 is lowered and the bottom template 130 is raised and folded to form an M-shaped structure that is detached from the inner wall of the narrow space 300.

[0051] In other alternative embodiments, the bottom of one or two end templates 140 can also be hinged to one end of the bottom template 130. In this case, when removing the two end templates 140 that are attached to the two end walls of the narrow space 300 in step three, the end template 140 that is hinged to one end of the bottom template 130 can be rotated to fit the top surface of the bottom template 130 and then fixed with steel bars. Subsequently, along with the upper inner template 100 and the lower inner template 110, the top template 120 is lowered and the bottom template 130 is raised and folded to form an M-shaped structure that detaches from the inner wall of the narrow space 300.

[0052] In other alternative embodiments, the two end templates 140 can also be hinged to one end of the top template 120 and the bottom template 130, respectively. In this case, when removing the two end templates 140 that are attached to the two end walls of the narrow space 300 in step three, the two end templates 140 can be rotated to fit the top template 120 and the bottom template 130 and then fixed with steel bars. Subsequently, along with the inner upper template 100 and the inner lower template 110, the top template 120 is lowered and the bottom template 130 is raised and folded to form an M-shaped structure that detaches from the inner wall of the narrow space 300.

[0053] In other optional embodiments, one or two end templates 140 may also include an upper end template 141 hinged to one end of the top template 120 and a lower end template 142 hinged to one end of the bottom template 130. In this case, when removing the two end templates 140 that are attached to the end walls of the narrow space 300 in step three, the upper end template 141 and the lower end template 142 are rotated to fit the top template 120 and the bottom template 130 respectively and then fixed with steel bars. Subsequently, along with the inner upper template 100 and the inner lower template 110, the top template 120 is lowered and the bottom template 130 is raised and folded to form an M-shaped structure that detaches from the inner wall of the narrow space 300.

[0054] The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
