Description

TECHNICAL FIELD

[0001] The present application relates to the field of building construction, and is a chiseling-free formwork structure for concrete pouring construction and a construction method thereof. BACKGROUND

[0002] Chiseling is a process of chiseling a rough structure such as a groove on a completed concrete structure surface, which is a conventional measure for firm and stable combination of new and old concrete. The existing chiseling method is usually tool chiseling, that is, a special chiseling tool is used to chisel the surface of the formed concrete structure, which not only has high labor intensity, is time-consuming and laborious, and has low efficiency, but also easily damages the main body of the concrete structure. In order to solve the technical problem, the prior art discloses a chiseling-free gushing stop strip, which is usually made of a new type of composite fiber material, has good wear resistance and tensile resistance, and has a rough surface. When pouring concrete, the chiseling-free gushing stop strip is fixed on the surface of the formwork, and when the concrete is poured and formed, the chiseling-free gushing stop strip is torn off to form a chiseling structure on the surface of the concrete structure, which not only saves time and labor, has high efficiency, and has stable chiseling structure and high firmness of combination of new and old concrete. However, in the existing construction process, the formwork is usually spliced by wood formwork, and the formwork itself is time-consuming and laborious to build and lay. The chiseling-free gushing stop strip and the formwork need to be manually bound or nailed, which is obviously still a large amount of work to lay the formwork and the chiseling-free gushing stop strip, and has high construction intensity and low overall efficiency. In addition, due to manual laying, the formwork is uneven, and it is difficult to control the binding and nailing, which easily leads to uneven laying of the chiseling-free gushing stop strip, many wrinkles, and affects the formation of the chiseling surface. Therefore, it is necessary to improve the chiseling-free construction of the existing concrete structure. SUMMARY

[0003] In order to overcome the above-mentioned deficiencies, the present application aims to provide a chiseling-free formwork structure and a construction method thereof in the field, which solves the technical problems of the existing chiseling-free gushing strip and formwork laying construction, which is complicated, has high labor intensity, low construction efficiency, and poor chiseling surface forming quality. The purpose is achieved through the following technical solutions.

[0004] The invention discloses a kind of free gouging formwork structure, which is used for the fixing of wood template and free gouging dampproofing strip of template surface, and the structure is as follows: the formwork structure includes upper clamp seat, lower clamp seat, locking screw and locking nut; the lower clamp seat includes horizontal bottom plate, vertically fixed lower baffle and lower clamp strip relative to the bottom plate, and lower baffle and lower clamp strip form lower clamping space for clamping wood template and free gouging dampproofing strip; the upper clamp seat includes horizontal top plate, vertically fixed upper baffle and upper clamp strip relative to the top plate, and upper baffle and upper clamp strip form upper clamping space for clamping wood template and free gouging dampproofing strip; the lower end of the locking screw is fixed to the lower clamp seat, the top end of the locking screw passes through the top plate of the upper clamp seat and is threadedly connected to the locking nut, and when the locking nut is locked, the upper clamp seat and the lower clamp seat form upper and lower clamping of the wood template.By the above structure, the wood template is positioned and supported, and the free gouging dampproofing strip can be quickly clamped and fixed on the surface of the wood template, and the clamped free gouging dampproofing strip can still be adjusted in position to meet the required position requirements, effectively preventing deformation, wrinkles and other problems, and ensuring the quality of gouging surface after concrete pouring.

[0005] The upper baffle and the lower baffle are integral plates or at least two separate plates in the same plane. By this structure, the wood template is reliably limited, and the concrete pouring operation is facilitated, i.e., before the concrete pouring mold frame, the steel bars are often arranged in the mold frame, and the horizontal steel bars often pass through the wood template. The separate plates of the upper baffle and the lower baffle are beneficial to avoid the interference between the upper baffle, the lower baffle and the horizontal steel bars as much as possible.

By this structure, the upper clamp strip and the lower clamp strip can clamp the free gouging dampproofing strip, and the shielding of the free gouging dampproofing strip is reduced as much as possible, so that the surface of the free gouging dampproofing strip can fully combine with the concrete to form a gouging surface, and the quality of the gouging surface is ensured.

[0007] The upper clamp seat and the lower clamp seat are clamped by at least two spaced locking screws and the locking nut. By this structure, the support stability of the formwork structure is improved, for example, when the formwork structure clamps two abutting wood templates, the double locking screws are more reliable and stable than the single locking screw.

[0008] The upper clamping strip and the lower clamping strip of the upper clamping seat and the lower clamping seat are replaced by the insertion strip, that is, the top plate and the bottom plate are omitted, the top plate and the bottom plate are provided with insertion holes for inserting the insertion strip, the insertion strip is inserted into the insertion hole of the top plate and is limited by the insertion hole of the bottom plate, and the insertion strip and the upper baffle and the lower baffle form a clamping space for clamping the wood formwork and the stop mortar strip. Through the structure, the upper clamping strip and the lower clamping strip are replaced by the insertion strip, and the clamping is realized by the insertion mode, so that the operation is more convenient, the insertion strip can be pulled out after the concrete is poured, the stop mortar strip without chiseling can be completely combined with the concrete pouring surface, and a more complete chiseled surface is formed.

[0009] The top of the insertion strip is provided with a pull ring or a hook part. Through the structure, the manual insertion and extraction operation of the insertion strip is facilitated.

[0010] Based on the structure of the upper clamping strip and the lower clamping strip, a construction method of the chisel-free formwork structure is provided, and the method comprises the following construction steps:

[0011] I. Select the corresponding number of formwork structures according to the length of the wood formwork.

[0012] II. Place the wood formwork and the chisel-free stop mortar strip in the lower clamping space of the lower clamping seat to form lower clamping.

Place the upper part of the wood formwork and the chisel-free stop mortar strip in the upper clamping space of the upper clamping seat to form upper clamping, and pass the upper end of the locking screw of the lower clamping seat through the corresponding through hole of the top plate of the upper clamping seat.

[0014] IV. Connect the locking nut at the top of the locking screw to drive the upper clamping seat and the lower clamping seat to clamp the wood formwork from top to bottom. After clamping from top to bottom, adjust the position and flatness of the chisel-free stop mortar strip, that is, complete the support and fixation of the wood formwork and the chisel-free stop mortar strip by the formwork structure.

[0015] Based on the structure of the insertion strip, a construction method of the chisel-free formwork structure is provided, and the method comprises the following construction steps:

[0016] I. Select the corresponding number of formwork structures according to the length of the wood formwork.

[0017] II. Pass the upper end of the locking screw of the lower clamping seat through the corresponding through hole of the top plate of the upper clamping seat and connect the locking nut.

[0018] III. Place the wood formwork between the upper baffle and the lower baffle on one side of the upper clamping seat and the lower clamping seat to form a limit, and at the same time, lock the locking nut, so that the upper clamping seat and the lower clamping seat clamp the wood formwork.

[0019] Four, the pre-paste of the chisel-free and grout-stopping tape on the surface of the wooden formwork is realized by manually pressing, and the insertion of the inserted strip forms clamping and limiting on the chisel-free and grout-stopping tape, and after the clamping and limiting, the manual pressing is released, the position and flatness of the chisel-free and grout-stopping tape are adjusted, and the support and fixation of the formwork structure on the wooden formwork and the chisel-free and grout-stopping tape are completed.

[0020] In the above method, the inserted strip is taken out after the pouring of the mold frame formed by the wooden formwork, that is, the inserted strip can be taken out, so that the chiseled surface of the chisel-free and grout-stopping surface can be fully attached to the poured concrete, and a more complete chiseled surface is formed.

[0021] In the above method, the wooden formwork is connected with the steel bars, and the steel bars are fixed by being tied with the locking screw adjacent to the steel bars.

[0033] The present invention will now be further described with reference to the accompanying drawings.

[0034] like Figure 1 , Figure 2 As shown, the no-scraping formwork structure is used to fix the wooden formwork 9 and the no-scraping grout-stopping strip 10 on the surface of the formwork. The formwork structure is made of steel or hard alloy. The formwork structure includes an upper clamp, a lower clamp, a locking screw 7, and a locking nut 8. The lower clamp includes a horizontal base plate 1, a lower baffle 2 and a lower clamping strip 3 that are vertically fixed relative to the base plate 1. The lower baffle 2 and the lower clamping strip 3 form a lower clamping space for clamping the wooden formwork 9 and the no-scraping grout-stopping strip 10. The upper clamp includes a horizontal top plate 4, an upper baffle 5 and an upper clamping strip 6 that are vertically fixed relative to the top plate 4. The upper baffle 5 and the upper clamping strip 6 form an upper clamping space for clamping the wooden formwork 9 and the no-scraping grout-stopping strip 10. That is, the upper clamping space and the lower clamping space form a clamping of the wooden formwork 9 and the no-scraping grout-stopping strip 10. The bottom end of the locking screw 7 is fixed to the lower clamping seat, and the top end of the locking screw 7 passes through the top plate 4 of the upper clamping seat and is threaded to the locking nut 8. When the locking nut 8 is tightened, the upper clamping seat and the lower clamping seat form an upper and lower clamping of the wooden template 9.

[0035] The aforementioned upper baffle 5 and lower baffle 2 are either a single plate or at least two separate plates arranged on the same plane. For example... Figure 1 The image shows a monolithic structure, as shown below. Figure 3 The diagram shows a panel structure; the gaps between the panels can be easily [used for this purpose]. Figure 6 The reinforcing bars shown pass through the wooden formwork 9.

[0036] In order to minimize the obstruction of the non-chiseling grout-stopping strip 10 while ensuring that the upper clamping strip 6 and the lower clamping strip 3 can clamp the non-chiseling grout-stopping strip 10, the upper clamping strip 6 and the lower clamping strip 3 are long strips, so that the non-chiseling grout-stopping strip 10 can fully bond with the concrete to form a chiseled surface and ensure the quality of the chiseled surface.

[0037] like Figure 5 , Figure 6 The diagram shows the supporting and fixing structure for the wooden formwork 9 and the no-scraping grout-stopping strip 10 in a partial formwork structure. The construction method includes the following steps:

[0038] I. According to the construction requirements of the field mold, the corresponding wood mold plate 9 is selected, and the number of the formwork structure is arranged at intervals according to the length of the wood mold plate 9, so as to meet the requirements of the wood mold plate 9 and the non-chiseling and stopping of the gusset strip.

[0039] II. The wood mold plate 9 and the non-chiseling and stopping gusset strip are placed in the lower clamping space of the lower clamping seat to form a lower clamping, and in this way, the lower clamping of all lower clamping seats to the corresponding wood mold plate 9 is completed.

[0040] III. The upper part of the wood mold plate 9 and the non-chiseling and stopping gusset strip is placed in the upper clamping space of the upper clamping seat to form an upper clamping, and at the same time, the upper end of the locking screw 7 of the lower clamping seat passes through the corresponding through hole of the upper clamping seat top plate 4, and in this way, the upper clamping of all upper clamping seats to the corresponding wood mold plate 9 is completed.

[0041] IV. The upper and lower clamping of the wood mold plate 9 is formed by connecting the locking nut 8 at the top of the locking screw 7 to drive the upper clamping seat and the lower clamping seat, and after the upper and lower clamping, the position and flatness of the non-chiseling and stopping gusset strip 10 are adjusted, that is, the support and fixation of the formwork structure to the wood mold plate 9 and the non-chiseling and stopping gusset strip 10 are completed.

[0042] V. The formwork structure itself can be fixed to the ground or other mold structure through external fixing members, and the fixing method can be arbitrary, which can be selected according to the construction environment, and details are not described here. After the support and fixation of the formwork structure, the concrete pouring of the mold can be carried out, and when the concrete is solidified or about to be solidified, the formwork structure can be removed in the reverse direction of the above operation, and at the same time, the non-chiseling and stopping gusset strip 10 can also be removed, which is convenient and efficient.

[0043] As shown in Figure 7 , when the transverse steel bar 11 in the concrete mold needs to pass through the wood mold plate 9, the wood mold plate 9 needs to be pre-slotted or holed according to the position of the steel bar, and after the lower clamping seat is clamped with the wood mold and the non-chiseling and stopping gusset strip 10, it needs to be installed along the axial direction of the transverse steel bar 11, and after installation, the clamping operation of the upper clamping seat and the locking nut 8 is carried out. After the formwork structure is installed in place, the locking screw 7 and the adjacent transverse steel bar 11 can also be fixed by fastening members or binding, so as to further improve the support stability of the formwork structure.

[0044] As shown in Figure 4 , in order to improve the support stability of the formwork structure, the upper clamping seat and the lower clamping seat can also be clamped by two locking screws 7 arranged at intervals and cooperating with the locking nut 8.

[0045] As shown in Figure 8 , Figure 9As shown, the upper clamping strip 6 and the lower clamping strip 3 of the upper clamping seat and the lower clamping seat can also be replaced by the insertion strip 13, that is, the top plate 4 and the bottom plate 1 omit the upper clamping strip 6 and the lower clamping strip 3, and the top plate 4 and the bottom plate 1 are provided with the insertion hole 12 for inserting the insertion strip 13, the insertion strip 13 is inserted into the insertion hole 12 of the top plate 4 to be limited by the insertion hole 12 of the bottom plate 1, and the insertion strip 13 and the upper baffle 5 and the lower baffle 2 form a clamping space for clamping the wood mold plate 9 and the grouting stop strip. The insertion strip 13 is preferably elastic to better clamp the grouting stop strip without chiseling, and the top can also be provided with a pull ring or a hook portion to facilitate manual extraction of the insertion strip 13.

[0046] The construction method of the chisel-free formwork structure based on the above-mentioned insertion strip 13 structure includes the following steps:

[0047] I. Select the corresponding number of formwork structures according to the length of the wood mold plate 9.

[0048] II. The upper end of the locking screw 7 of the lower clamping seat is inserted through the corresponding through hole of the top plate 4 of the upper clamping seat and connected with the locking nut 8.

[0049] III. The wood mold plate 9 is placed between the upper clamping seat and the lower clamping seat to form a limit on one side of the upper baffle 5 and the lower baffle 2, and at the same time, the locking nut 8 is locked, so that the upper clamping seat and the lower clamping seat clamp the wood mold plate 9.

[0050] IV. The chisel-free grouting stop strip 10 is pre-stuck on the surface of the wood mold plate 9 by manual pressing, and at the same time, the insertion strip 13 is inserted to clamp and limit the chisel-free grouting stop strip 10, and after clamping and limiting, the manual pressing is released, and the position and flatness of the chisel-free grouting stop strip 10 are adjusted, that is, the support and fixation of the wood mold plate 9 and the chisel-free grouting stop strip 10 by the formwork structure is completed.

[0051] V. This step is the same as the above-mentioned step V, the difference is that when the mold frame formed by the wood mold plate 9 is poured, the insertion strip 13 can be removed, so that the rough surface of the chisel-free grouting stop strip can be fully combined with the poured concrete to form a more complete chiseled surface.

[0052] The above content is intended to explain the technical means of the present application, not to limit the technical scope of the present application. The present application is not limited to the above two construction methods, and multiple groups of formwork structures can be provided for the same wood mold plate 9, or one group of formwork structures can be used as the butt joint operation of two wood mold plates 9, and the person skilled in the art can make obvious improvements or replacements to the present application combined with the existing common knowledge, which also falls within the protection scope of the claims of the present application.
