Description

Technical Field

[0001] This utility model relates to the field of building beam construction technology, specifically to a construction device for constructing beams with unequal height using equal-height beam side formwork. Background Technology

[0002] In current construction, prefabricated formwork without plastering, such as aluminum formwork, ribbed plastic formwork, and high-strength steel formwork, is widely used. However, in conventional formwork construction, beam side formwork corresponding to the different heights of the beam web is required. This not only increases the specifications and models of beam side formwork, causing inconvenience in formwork management and storage, but also hinders the reuse of formwork between different projects and between different areas and floors of the same project. Therefore, there is an urgent need for a construction device and method that can solve this problem. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a construction device for constructing beam webs of unequal height using equal-height beam side formwork, which can solve the problem that beam webs of different heights need to be equipped with beam side formwork of different specifications in the prior art, thereby improving the turnover rate of formwork and construction efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A construction device for constructing unequal-height beam webs using equal-height beam side formwork includes adjustable support poles, an adjustable-height early-removal top support for the beam bottom, beam bottom ribs and beam bottom formwork, double support beams, and beam side formwork. The double support beams are installed on the adjustable support poles, and their positions can be adjusted by adjusting the adjustable support poles. The beam side formwork is installed on the double support beams. The adjustable-height early-removal top support for the beam bottom is installed on the double support beams. The beam bottom ribs and beam bottom formwork are installed on the adjustable-height early-removal top support, and the beam bottom ribs and beam bottom formwork are located between the beam side formworks. The positions of the beam bottom ribs and beam bottom formwork can be adjusted by adjusting the adjustable-height early-removal top support, thereby realizing the construction of unequal-height beam webs.

[0006] Furthermore, the adjustable support pole includes an upper steel pipe, a first lead screw, a lower steel pipe, a connecting plate, an adjustable support, and a connecting sleeve; the first lead screw is located between the upper steel pipe and the lower steel pipe, the adjustable support is located on the first lead screw and is threadedly connected to the first lead screw, the connecting plate is located on the upper steel pipe and the lower steel pipe respectively, and the connecting sleeve is installed at the bottom of the lower steel pipe.

[0008] Furthermore, the adjustable support includes a support body, the middle of which has a threaded hole that matches the first lead screw.

[0009] Furthermore, the adjustable early-release top support at the bottom of the beam includes a top plate, a second lead screw, an early-release tray, a support tray, and a pressure plate; the top plate is fixed to the top of the second lead screw, and the early-release tray, support tray, and pressure plate are arranged sequentially on the second lead screw from top to bottom and are threadedly connected to the second lead screw.

[0010] Furthermore, the early-release pallet includes a pallet body, with a threaded hole in the center of the pallet body that matches the second lead screw. Limiting devices are provided on both sides of the pallet body to limit the movement of the beam bottom rib. Each limiting device includes a connecting pin and a limiting post. The limiting post has an oblong hole. The connecting pin is located on the pallet body and passes through the oblong hole of the limiting post. In use, lifting the limiting post allows it to rotate along the connecting pin. When lowering the limiting post, the limiting post is vertically locked between the pallet body and the connecting pin, thus limiting the movement of the beam bottom rib.

[0011] Furthermore, the longitudinal section of the bearing tray is inverted U-shape, and a threaded hole matching the second lead screw is opened in the middle.

[0012] Furthermore, the longitudinal section of the clamping plate is inverted U-shape, and a threaded hole matching the second lead screw is opened in the middle.

[0015] (2) Install the adjustable early removal top support on the double support beam, and then install the bottom rib and bottom formwork on the adjustable early removal top support. The bottom rib and bottom formwork are located between the side formwork of the beam. Then, according to different beam web heights, adjust the position of the bottom rib and bottom formwork by adjusting the adjustable early removal top support, and fix the adjustable early removal top support.
