Description

Technical Field

[0001] The present invention relates to the technical field of coping formwork support, and particularly to a fixing structure for a coping pouring formwork of doors and windows and a support method thereof. Background Art

[0002] The coping of doors and windows is an indispensable structure in construction. It can reduce or avoid the splayed cracks at the intersection of the two side walls and the window sill caused by stress concentration. It can prevent external rainwater from entering and affecting the strength of the lower wall, and increase the integrity and stability of the lower wall of the window sill. Therefore, the quality of formwork support before pouring determines the quality of concrete forming.

[0003] The traditional method for supporting the coping of doors and windows is to use wooden formwork and tie bolts, and reinforce with steel pipes. Since the upper part of the coping at the top of some door openings is a concrete structural beam, when pouring the coping concrete, there may be a situation where the coping concrete cannot be filled completely, resulting in exposed reinforcement. After a gap appears between the coping and the structural beam, there may be a risk of leakage due to improper sealing. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a fixing structure for a coping pouring formwork of doors and windows and a support method thereof, so as to achieve the technical effect that after the coping at the top of the door opening is formed, it is connected tightly with the concrete beam, and there are no cavities and exposed reinforcement phenomena.

[0005] To achieve this technical purpose, the present invention adopts the following scheme:

[0006] A support structure for a coping pouring formwork of doors and windows includes a wooden formwork and a reinforcement component placed outside the wooden formwork. One side of the wooden formwork protrudes outward to form a feeding port, and a reinforcement screw rod penetrates through the inside of the wooden formwork; the reinforcement component includes a shaped aluminum plate, the shaped aluminum plate is placed on the outer side of the wooden formwork, and one end of the reinforcement screw rod penetrates through one side of the shaped aluminum plate and is threadedly connected with the shaped aluminum plate; the other side and the bottom of the shaped aluminum plate respectively press against the wooden formwork tightly through the top-tightening screw rods arranged at intervals.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] This structure adds a feeding port at one end of the wooden formwork, and pours into the inside of the wooden formwork through the feeding port, ensuring that the post-cast concrete inside the wooden formwork is connected tightly with the concrete beam, and there are no cavities and exposed reinforcement phenomena; the shaped aluminum plate is used to fix and shape the wooden formwork, reducing the number of bolt holes, being easy to repair, and reducing the risk of leakage.

[0009] Further, the preferred scheme of the present invention is:

[0010] The wooden formwork includes a left side form, a right side form and a bottom form for connecting the left and right side forms. One end of the right side form protrudes to the right, and the protruding part and the left side form and the bottom form form a feeding port with a right trapezoidal cross-section structure.

[0011] The left side wall of the shaped aluminum plate is parallel to the left mold, the right side wall is parallel to the surface of the protruding part of the right mold, and the bottom plate is parallel to the bottom mold;

[0012] The left end of the reinforcing screw rod passes through the left mold and the left side wall in sequence and is tightened against the inner wall of the right mold of the wooden template. The reinforcing screw rod is threadedly connected to the left mold and the left side wall respectively.

[0013] The right side wall and the bottom plate of the shaped aluminum plate are respectively tightened against the wooden formwork through tightening screws arranged at intervals thereon.

[0014] Through holes are respectively opened on the left side mold of the wooden formwork and the left side wall of the shaped aluminum formwork. A backing plate with a threaded hole is respectively set outside each through hole. The reinforcing screw supports and shapes the wooden formwork by cooperating with the threaded hole on the backing plate.

[0015] Through holes are also provided on the right side wall and bottom plate of the shaped aluminum plate. A pad with a threaded hole is also provided on the outside of each through hole. The tightening screw is tightened against the wooden template by cooperating with the threaded hole on the corresponding pad.

[0016] A second pad is provided inside the right side mold of the wooden formwork corresponding to the end of the reinforcing screw, and a second pad is also provided outside the right side mold and the bottom mold corresponding to the position of each tightening screw.

[0017] The present invention also relates to a method for supporting a door and window top casting template, which is carried out according to the following steps:

[0018] S1. Construction preparation: Cutting and processing the wooden formwork, and opening through holes at the set positions of the wooden formwork and the shaped aluminum plate;

Detailed implementation manner

[0031] To fully understand the purpose, features and effects of the present invention, the present invention will be described in detail through the following specific implementation manners, as Figures 1 to 5 shown, but the present invention is not limited thereto.

[0032] A formwork support structure for pouring window and door lintels is composed of a wooden formwork 3 and a reinforcement component disposed outside the wooden formwork 3.

[0033] The wooden formwork 3 is composed of a left formwork 31, a right formwork 32 and a bottom formwork 33 for connecting the left and right formworks. One end of the right formwork 32 protrudes to the right, and the protruding part 34 and the left formwork 31 and the bottom formwork 33 form a feeding port 7 with a right - angled trapezoid cross - section structure. The end of the wooden formwork 3 with the feeding port 7 is 10 mm higher than the end without the feeding port.

[0034] The reinforcement component includes a shaped aluminum plate 4. The shaped aluminum plate 4 is disposed outside the wooden formwork 3. The left side wall 41 of the shaped aluminum plate 4 is arranged parallel to the left formwork 31 of the wooden formwork 3. The right side wall 42 of the shaped aluminum plate 4 is arranged parallel to the surface of the protruding part 34 of the right formwork 32 of the wooden formwork 3. The bottom plate 43 of the shaped aluminum plate 4 is arranged parallel to the bottom formwork 33 of the wooden formwork 3.

[0035] Through - holes for passing through the reinforcement screw 5 are respectively opened on the left formwork 31 of the wooden formwork 3 and the left side wall 41 of the shaped aluminum plate 4. Threaded spacer plates 8 are respectively installed outside each through - hole, and the threaded holes are arranged corresponding to the through - holes.

[0036] The reinforcing screw rod 5 horizontally penetrates through the left side form 31 and the left side wall 41 of the shaping aluminum plate 4, and then tightly abuts against the inner side of the right side form 32 of the wooden formwork 3. The reinforcing screw rod 5 shapes the wooden formwork 3 by being threadedly connected to the first backing plate 8 outside the wooden formwork 3, and reinforces the wooden formwork 3 by being threadedly connected to the first backing plate 8 outside the left side wall 41 of the shaping aluminum plate 4.

[0037] A number of through holes are also spaced apart on the right side wall 42 and the bottom plate 43 of the shaping aluminum plate 4. The first backing plate 8 with threaded holes is respectively arranged corresponding to the outside of each through hole. The tightening screw rod 6 realizes the tightening of the bottom form 33 and the right side form 32 of the wooden formwork 3 by cooperating with the threaded holes on the corresponding first backing plate 8. By turning the tightening screw rod 6, the tightening screw rod 6 is adjusted to squeeze the wooden formwork 3, playing the role of fixing the formwork.

[0038] In this embodiment, a second backing plate 9 is arranged inside the right side form 32 of the wooden formwork 3 corresponding to the end of the reinforcing screw rod 5. The second backing plate 9 is also respectively arranged corresponding to the position of each tightening screw rod 6 outside the right side form 32 and the bottom form 33. The reinforcing screw rod 5 and the tightening screw rod 6 tightly abut against the wooden formwork 3 through the second backing plate 9 to avoid damaging the wooden formwork 3 by directly contacting the wooden formwork 3.

[0039] When the above formwork erection structure is specifically constructed, it is carried out according to the following steps:

[0040] S1. Construction preparation: Cut and process the formwork. Through holes for penetrating the reinforcing screw rod 5 are opened on the left side form 31 of the wooden formwork 3 at an interval of 250 mm; 3 / 4 of the cross-section of the wooden formwork 3 in its length is of a U-shaped structure, and a feeding port 7 with a length increased by 300 mm is added to 1 / 4 of its length. The feeding port 7 is 10 mm higher than the U-shaped part.

[0041] The left side wall 41 of the shaping aluminum plate 4 also opens through holes for penetrating the reinforcing screw rod 5 corresponding to the through hole positions on the wooden formwork 3, and through holes for penetrating the tightening screw rod 6 are equally spaced on the right side wall 42 and the bottom plate 43.

[0042] S2. After the construction of the main structure and the frame columns or the two side walls 1 at the location of the to-be-constructed door opening are completed, install the shaping aluminum plate 4 between the frame columns or the two side walls 1 and under the concrete beam 2, then install the wooden formwork 3 inside the shaping aluminum plate 4, and shape the wooden formwork 3 through the reinforcing screw rod 5.

[0043] S3. Reinforce the wooden formwork 3 by installing the tightening screw rod 6 at the right side wall 42 and the bottom plate 43 of the shaping aluminum plate 4.

[0044] S4. Pour the concrete.

[0045] S5. After the concrete reaches the strength, remove the shaping aluminum plate and the wooden formwork 3 in sequence.

[0046] After the formwork is removed, fill the holes of the reinforcement screw rod 5 on the coping with foam, and cut off the protrusions at the position of the feeding port 7 at the lower end.

[0047] In this embodiment, the reinforcement screw rod 5 is a through-long screw rod penetrating the wooden formwork 3. The reinforcement screw rod 5 is used to shape the wooden formwork 3, and the tightening screw rod 6 is used to reinforce and tighten the wooden formwork 3 in cooperation with the shaped aluminum plate 4.

[0048] The present invention uses a shaped aluminum plate to replace the traditional steel pipe for fixation, which is convenient and fast to install; after the coping is formed by this method, it is densely connected with the concrete, without voids and exposed reinforcement phenomena, and there are few bolt holes in the later stage, which have been repaired, reducing the risk of leakage.

[0049] Finally, it should be noted that the above-listed are only the preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and its equivalent technologies, they should all be considered as the protection scope of the present invention.
