Description

Technical Field

[0001] This utility model relates to the field of top formwork support structures, and in particular to a top formwork support structure. Background Technology

[0002] When installing roof slabs on a construction site, precast slabs are usually used for sealing because the precast slabs are of uniform size, while the area to be sealed on the construction site is relatively large. Furthermore, precast slabs need to be directly connected by pouring crossbeams to ensure the stability and reliability between them. This requires installing two precast slabs by pouring cement into each other.

[0003] Typically, a top formwork is installed at the bottom of two precast slabs that need to be filled with cement, placed at the bottom of the space where cement needs to be poured. However, in current technology, long support plates are often used to support the top formwork. This requires a lot of long support rods to support the top formwork. Because using long support rods to support the top formwork can easily cause grout to leak from the side of the top formwork when cement is poured, workers will need to grind it down afterward, which is time-consuming and laborious.

[0004] Furthermore, because the precast slabs on top also require long support columns to be installed underneath to support the top formwork, more long support columns need to be installed on the lower level, which increases the installation and dismantling time for workers, as well as the cost of using the long support columns. It also makes the lower level space more crowded and inconvenient for workers to enter to erect scaffolding and other structures.

[0005] Therefore, it is particularly important to design a top formwork support structure that is easy for workers to erect quickly, has a reliable support structure, can effectively support the top formwork to reduce grout leakage, and at the same time increase the working space below and facilitate worker movement.

[0030] An embodiment of this utility model provides a top template support structure.

[0031] like Figure 1-6 As shown in the attached diagram, only a portion of the support structure on the precast slab is displayed. One type of top formwork support structure is mounted on the top formwork 8, supporting it. The top formwork 8 is located in the pouring area between two precast slabs 10, where cement is poured. A thick steel bar 1 is mounted on the support structure, supporting the two precast slabs 10. A sleeve 2 is welded to the steel bar 1. The sleeve 2 is cylindrical and has internal threads. A screw 3 is mounted on the sleeve 2, with external threads matching the internal threads of the sleeve 2. The screw 3 is screwed into the sleeve 2 via the threads. A movable U-shaped clamp 4 is mounted on the screw 3. Each side of the U-shaped clamp 4 has an arc-shaped groove, and a through hole in the middle for the screw 3 to pass through. A nut 5 is also mounted on the screw 3.

[0032] The connections between precast slabs 10 are reinforced with transverse and longitudinal steel bars to strengthen the pouring area between them. A square top formwork 8 is installed on the bottom side of the pouring area of ​​the precast slabs 10, completely covering the area. The top formwork 8 has several holes, each fitted with a plastic tube 6. The plastic tube 6 can pass through a threaded rod 3, and the sleeve 2 on the thick steel bar 1 contacts and fits against the plastic tube 6. During installation, several fixing plates 7 are installed at the bottom of the top formwork 8. Two metal round tubes 6 are installed on the bottom side of the fixing plates 7, fitting into the grooves of the mountain-shaped clamps 4. Tightening the nuts moves the mountain-shaped clamps 4 upwards, reducing the gap between the thick steel bar 1 and the mountain-shaped clamps 4, thus ensuring the top formwork 8 is clamped and fixed. Cement is then poured into the pouring area between the precast slabs 10. The spacing between the two precast slabs 10 is 40-60 cm, and the length of the thick steel bar 1 is 60-80 cm. The top formwork can be made of wood, aluminum, or steel.

[0033] The construction method for the top formwork support structure is as follows:

[0034] Step A: Pass the screw rod 3 through the mountain-shaped clip 4 with the grooved side of the mountain-shaped clip 4 facing upwards. Set up the top template 8 and pass the screw rod 3 through the plastic pipe 9 on the top template 8 and tighten the sleeve 2 of the thick steel bar 1 in the pouring area between the plastic pipe 9 and the precast slab 10. During installation, align the opening of the plastic pipe 9 with the sleeve 2.

[0035] Step B: Install the two round tubes 6 into the groove of the mountain-shaped clip 4, and at the same time install the fixing plate 7 between the top template 8 and the round tubes 6, and tighten the nut 5 upwards to fix the top template 8.

[0036] Step C: Set corresponding holes and slots on the sides of the pouring area between precast slabs 10, and install the reinforcing bars in the holes and slots of the left and right precast slabs 10 to connect the precast slabs 10 laterally. At the same time, erect the reinforcing bars longitudinally and tie the transverse and longitudinal reinforcing bars to form a reinforcing mesh.

[0037] Step D: Pour cement into the pouring area of ​​the precast slab 10. After the cement dries, loosen the nut 5, place the mountain-shaped clip 4 downwards, loosen the screw 3 that is tightened with the sleeve 2, unscrew the screw 3 and remove the top formwork 8. Cut off the part of the plastic pipe 9 on the top formwork 8 that extends beyond the pouring cement.

[0038] Step E: Finally, pour cement into the precast slab 10 and pour cement into the thick steel bars 1 placed on the precast slab 10.

[0039] The support structure of this device ensures a tight fit between the top formwork and the precast slab, preventing grout leakage during top formwork pouring and eliminating the need for post-pouring work by workers, thus improving work efficiency.

[0040] Compared with the long rod support used in the prior art, the support structure of this device is more compact and flexible. It uses a thick steel bar 1 as the entire support surface, and uses a mountain-shaped clamp 4 to fit a round tube 6 to maintain a stable and reliable contact between the top template 8 and the precast slab. This makes it easier to pour and assemble the two precast slabs. After pouring, the top template 8 can be quickly disassembled by unscrewing the screw 3. The remaining parts can also be reused next time. At the same time, the thick steel bar 1 on the precast slab 10 will be poured into the cement during the subsequent pouring of the entire precast slab 19. The whole process is convenient, fast and convenient. After the top template 8 is removed, the plastic tube 9 on the top template 8 solidifies into one piece due to the contact with cement. The plastic tube 9 in the pouring area that exceeds the limit is then cut off.

[0041] The installation of this device allows for a larger working space on the lower level of the precast slab 10, facilitating worker movement. Furthermore, this device is less expensive than existing long-pole support columns, is quick to install, and easy to disassemble. Additionally, the upper-mounted thick steel bars 1 can be cast into the interior along with the cement, eliminating the need for additional recycling.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects. The scope of this invention is defined by the appended claims, not by the foregoing description, and is therefore intended to encompass all variations falling within the meaning and scope of equivalents of the claims. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
