Description

Technical Field

[0001] The utility model relates to a formwork device, in particular to a formwork device for an interior partition wall lintel. Background Art

[0002] In the secondary structure construction stage of a building project, as a key component connecting the walls on both sides of a door or window opening, the construction quality and efficiency of a lintel are directly related to the safety of the overall building and the construction progress. The construction method of traditional lintel formwork mostly uses on-site wooden formwork fabrication and support, and there are some deficiencies in this method.

[0003] Firstly, the production cycle of wooden formwork is long, and it is difficult to ensure dimensional accuracy, which easily leads to dimensional deviation in lintel pouring, affecting the aesthetics and functionality of subsequent decoration and use. At the same time, the consumption of wooden formwork materials is large, and the reuse rate is low, which does not meet the requirements of green construction and energy conservation and emission reduction.

[0004] Secondly, the support system of traditional lintel formwork is complex, and a large number of scaffolds and support members need to be erected, which not only increases the construction difficulty and cost, but also occupies a large amount of construction space, affecting the movement efficiency of personnel and materials. Content of the Utility Model

[0005] The purpose of the utility model is to provide a formwork device for an interior partition wall lintel to solve the problems of poor accuracy and complex structure of the traditional lintel formwork device.

[0006] The utility model is realized as follows: A formwork device for an interior partition wall lintel, the structure of which includes a formwork component and a formwork support component; the formwork component includes a bottom formwork and two side formworks arranged on the bottom formwork; the formwork support component includes a side formwork support component and a bottom formwork support, and the bottom formwork support includes a vertical pipe, a top support inserted into the vertical pipe, and a fixing plate and an inclined strut arranged on the outer wall of the vertical pipe. The other end of the inclined strut is connected to the lower part of the bottom formwork. The fixing plate is horizontally arranged, and the fixing plate is used for inserting into the partition wall gap.

[0007] Further, the fixing plate is connected to the side of the vertical pipe adjacent to the partition wall, and the inclined strut is connected to the side of the vertical pipe away from the partition wall.

[0008] Further, the bottom formwork includes a grooved plate with the groove opening facing downwards and two L-shaped baffles respectively connected to the outer sides of the two side walls of the grooved plate.

[0009] Further, secondary ribs and main ribs are arranged in the groove opening of the grooved plate.

[0010] Further, reinforcing plates are arranged near both ends of the lower side of the grooved plate.

[0011] Furthermore, the top support includes a top support screw rod, a top support nut screwed onto the top support screw rod, and a top plate connected to the top support screw rod.

[0012] Furthermore, a vertical plate is provided on the vertical pipe, and the vertical plate is arranged on the side adjacent to the partition wall.

[0013] Furthermore, the diagonal bracing rod is a telescopic rod, and the diagonal bracing rod is respectively hinged to the vertical pipe and the bottom formwork.

[0014] Furthermore, connecting ear plates are provided on both the vertical pipe and the bottom formwork, and through holes matching with them are opened at both ends of the diagonal bracing rod.

[0015] Furthermore, the side formwork support assembly includes a screw rod passing through two side formworks, and a retaining piece and a nut sleeved on the screw rod.

[0016] The structure of the utility model is stable. The fixing plate is horizontally inserted into the gap of the partition wall, providing a stable fulcrum for the bottom formwork support. The diagonal bracing rod converts the downward pressure of the bottom formwork into a downward-slanting force, which is transmitted to the fixing plate through the vertical pipe, and then the force is dispersed to the partition wall. This mechanical structure makes the bottom formwork support more stable when bearing the bottom formwork and its upper load, not easily displaced or overturned, and ensures the dimensional accuracy of the lintel.

[0017] The utility model connects the middle parts of the vertical pipe and the bottom formwork through the diagonal bracing rod, which not only supports the middle part of the bottom formwork but also avoids setting a support rod in the middle of the bottom formwork, facilitating the passage of workers and equipment and improving the moving efficiency of personnel and materials.

[0018] The utility model simplifies the construction process of the lintel, reduces the operation difficulty and labor intensity of construction workers. The construction workers only need to install the formwork, bind the steel bars and pour the concrete according to the established steps, without the need to carry out complex formwork production and support erection work.

[0019] The utility model realizes the rapid installation and disassembly of the lintel formwork through the prefabricated formwork assembly and the support assembly, reduces the time for on-site formwork production, and speeds up the construction progress; at the same time, the standardized design of the formwork assembly improves the reuse rate and reduces material waste.

[0020] The utility model has strong adaptability. The design of the bottom formwork support and the diagonal bracing rod takes into account the construction requirements of lintels with different widths and heights. By adjusting the length of the telescopic rod and the height of the top support, it can adapt to the pouring of lintels under different construction conditions, improving the versatility and practicality of the formwork assembly.

[0028] As Figure 1 shown, the utility model includes a template component and a template support component.

[0029] As Figure 2 shown, the template component includes a bottom template horizontally arranged at the bottom and two side templates 1 vertically arranged on the bottom template. The length of the bottom template is equivalent to the width of the door and window opening. The length of the side template 1 is greater than the length of the bottom template, and the length of the side template 1 is greater than the length of the lintel to ensure that the side template can fully cover both sides of the lintel notch. Two grooves are arranged on the bottom template, and the grooves are used for inserting the two side templates 1. The two grooves are respectively located at the edges of the front and rear sides of the bottom template. The bottom template includes a grooved plate 2 with the groove opening facing downwards and two L-shaped baffles 3 respectively connected to the outer sides of the front and rear side walls of the grooved plate 2. The L-shaped baffle 3 and the side wall of the grooved plate 2 form two grooves for inserting the side template 1. The free end of the lower part of the L-shaped baffle 3 is connected to the outer side wall of the grooved plate 2, and the other end is vertically arranged. The L-shaped baffle 3 and the outer side wall of the grooved plate 2 form a groove for accommodating the side template 1.

[0030] As Figure 3 shown, a main rib 16 and several secondary ribs 17 are arranged on the lower side of the grooved plate 2. The main rib 16 is arranged along the length direction of the grooved plate 2, and the secondary ribs 17 are perpendicular to the main rib 16. Reinforcing plates 18 are arranged near both ends of the lower side of the grooved plate 2 to enhance the shear resistance of the template end. The reinforcing plates 18 are used for contacting with the support.

[0031] In this embodiment, the channel plate 2 and the L-shaped baffle 3 are aluminum plates with a thickness of 5 mm, and the side formwork 1 is a 5-mm-thick reinforced honeycomb aluminum plate with a hollow honeycomb inside to reduce the weight while ensuring its strength. The formwork assembly can also be made of iron plates or steel plates.

[0032] The formwork support assembly includes a number of side formwork support assemblies and two bottom formwork supports. The side formwork support assemblies are used to support and limit the upper parts of the two side formworks 1 to ensure the pouring accuracy of the lintel. The two bottom formwork supports are symmetrically arranged on the wall below the bottom formwork, and the two bottom formwork supports respectively support one end of the lower side of the bottom formwork. The side formwork 1 support assembly includes a screw rod 4 that is commonly passed through the two side formworks 1, and a retaining piece 5 and a nut 6 sleeved on the screw rod 4. Corresponding through holes are opened in the two side formworks 1, and the screw rod 4 is passed through the corresponding through holes of the two side formworks 1. Both ends of the screw rod 4 protrude from the two side formworks 1, and the retaining piece 5 and the nut 6 are located on the screw rod 4 section outside the two side formworks 1. In this embodiment, the screw rod 4 is a through-thread screw rod with a diameter of 8 mm, and the retaining piece 5 is a 5-mm-thick aluminum circular retaining piece.

[0033] As Figure 4 and Figure 5 shown, the bottom formwork support includes a vertical pipe 7, a jack supported in the vertical pipe 7, and a fixing plate 9 and a diagonal brace 10 arranged on the outer wall of the vertical pipe 7. The other end of the diagonal brace 10 is connected to the lower part of the bottom formwork. The vertical pipe in this embodiment is a steel pipe with a size of 48.5×3.0. The fixing plate 9 is horizontally arranged, and the fixing plate 9 is used to horizontally insert into the gap of the partition wall 8 to fix the bottom formwork support. In this embodiment, the fixing plate 9 is an angle plate, which is a common profile in engineering. One side of the angle plate is horizontally arranged, and the other side is vertically arranged. The horizontal side is used to insert into the gap of the partition wall 8, and the vertical side is used to increase the contact area with the partition wall to make the whole more stable. The angle plate is an angle iron with a size of 50×50×5. A vertical plate 14 is arranged on the side of the vertical pipe 7 adjacent to the partition wall. The vertical plate 14 is used to increase the contact surface between the vertical pipe and the partition wall 8. The vertical plate 14 and the fixing plate 9 are symmetrically arranged at the upper and lower parts of the vertical pipe 7. In this embodiment, the vertical plate 14 is a steel plate with a size of 150×50×5. There are two groups of bottom formwork supports, which are symmetrically arranged on the partition wall 8 walls on the left and right sides of the door and window openings.

[0034] The fixed plate 9 is arranged on the side of the vertical pipe 7 adjacent to the partition wall 8, and the diagonal brace 10 is arranged on the side of the vertical pipe 7 away from the partition wall 8 to ensure that the support device is not easily displaced or overturned when bearing the bottom formwork and the loads above it. One end of the diagonal brace 10 is connected to the middle of the bottom formwork. The vertical pipe 7 is subjected to the obliquely downward force of the diagonal brace 10. The diagonal brace 10 converts the downward pressure of the bottom formwork into an obliquely downward force and transmits it to the vertical pipe 7. The vertical pipe 7 converts the obliquely downward force into a horizontally inward force towards the partition wall 8 and a vertically downward force. The horizontally inward force towards the partition wall 8 makes the vertical pipe 7 firmly lean against the partition wall, and the vertically downward force is dispersed by the partition wall below the fixed plate 9 to better support the bottom formwork.

[0035] As Figure 6 shown, the diagonal brace 10 is a telescopic rod to adapt to the lintels of different widths and install the bottom formwork support device at different heights. A fixing mechanism is arranged on the telescopic rod to fix it after adjusting the length of the telescopic rod. The two ends of the diagonal brace 10 are respectively hinged to the vertical pipe 7 and the bottom formwork to facilitate the adjustment of the length of the diagonal brace 10. Specifically, connecting ear plates 15 are arranged at the lower parts of the vertical pipe 7 and the bottom formwork, through holes matching with them are opened at both ends of the diagonal brace 10, and the diagonal brace 10 is connected to the connecting ear plate 15 through bolts or pins.

[0036] The top support includes a top support screw 11, a top support nut 12 screwed on the top support screw 11, and a top plate 13 arranged on the top support screw 11. The lower end of the top support screw 11 is inserted into the vertical pipe 7, the top plate 13 supports on the lower side of the bottom formwork, the top plate 13 is a grooved plate with the groove opening upwards, and the width of the groove opening of the top plate 13 is greater than the width of the bottom formwork. The diameter of the top support screw is 32 mm, and the width of the top plate is 200 mm. By rotating the position of the top support nut 12 on the top support screw 11, the height of the top plate 13 can be adjusted.

[0037] The usage method of the utility model is as follows:

[0038] 1. First, build the partition wall 8 to a height slightly higher than the lintel, reserve notches for pouring the lintel on the partition walls on both sides of the door and window openings, and leave a gap for inserting the fixed plate 9 on the partition wall 8;

[0039] 2. Fix the bottom formwork support device in the gap below the partition wall lintel, and fix the bottom formwork support devices on both sides of the opening in the gaps at the same height;

[0040] 3. Adjust the height of the top plate to reserve the bottom thickness of the bottom formwork, that is, make the height difference between the bottom of the top support and the bottom of the preset lintel equal to the distance from the lower end of the bottom formwork to the upper end of the grooved plate 2;

[0041] 4. Place the bottom formwork on the bottom formwork support device, adjust the length of the diagonal brace 10, and connect the diagonal brace 10 to the vertical pipe 7 and the bottom formwork respectively;
