Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a novel beam side formwork reinforcement device. Background Technology

[0002] During beam construction on site, if the beam sides are not reinforced, there is a risk of formwork bulging. Generally, the beam reinforcement is placed first, and tie rods or tie wires are inserted into the beam section for reinforcement. However, for beams with large cross-sectional dimensions, it is not possible to insert tie rods or tie wires for formwork reinforcement after placing the beam reinforcement.

[0003] The existing technical solution is to skip installing one section of the beam formwork when encountering beams with large cross-sectional dimensions. After the beam reinforcement is placed, tie rods or tie bolts are then inserted. However, this solution makes it difficult to install the beam side formwork after the floor formwork has been installed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel beam side formwork reinforcement device that enables the beam side formwork to be installed in one go, without the need for tie plates or tie rods used for beam side formwork reinforcement.

[0005] Specifically, this utility model provides the following technical solution:

[0006] A novel beam side formwork reinforcement device includes vertical steel pipes, diagonal steel pipes, and positioning bolts.

[0007] The vertical steel pipe is vertically installed on the outer side of the beam side formwork, with a horizontally penetrating positioning groove opened at its middle end along the length direction, and the bottom end is fixedly connected to the beam side formwork.

[0008] The oblique steel pipe is obliquely installed between the floor formwork and the vertical steel pipe, with its top end fixedly connected to the floor formwork and its bottom end having a horizontally penetrating bolt hole.

[0009] The positioning bolt passes through the bolt hole and extends into the positioning groove.

[0010] Preferably, the bottom end of the vertical steel pipe is provided with an extension, which is located inside the beam side formwork. The bottom of the extension is provided with a first pin, which is fixed to the beam side formwork.

[0011] Preferably, the top end of the rhomboid steel pipe is located inside the floor formwork and is provided with a second pin, which is fixed to the floor formwork.

[0012] Preferably, the angle of inclination of the rhomboid steel pipe relative to the vertical steel pipe is 45 degrees.

[0013] Preferably, the width of the positioning groove is adapted to the width of the opposite side of the head of the positioning bolt.

[0014] The beneficial effects of this utility model are at least as follows:

[0015] 1) The present invention provides a novel beam side formwork reinforcement device, wherein the oblique force provided by the oblique steel pipe is decomposed into horizontal and vertical forces, and the horizontal force provides horizontal support to the vertical steel pipe by means of angle self-locking, thereby reinforcing the beam side formwork;

[0016] 2) The present invention provides a novel beam side formwork reinforcement device, wherein the vertical steel pipes set on the outer side of the beam side formwork can ensure that the joints of the beam side plates do not expand outward, and can also be adapted to oblique steel pipes of different heights through the positioning groove.

[0017] 3) The present invention provides a novel beam side formwork reinforcement device, which, compared with the prior art, enables the beam side formwork to be installed in one go without the need for tie plates or tie rods for beam side formwork reinforcement, thereby reducing the installation difficulty of beam side formwork, improving installation efficiency, and reducing voids generated during construction.
