Problems solved by technology

In the actual construction process, workers often lie on the formwork and use hand drills and special drills to open holes. Not only is the operation inconvenient, the forming effect is poor (the same group of holes is prone to inconsistent high and low positions), and the work efficiency is low. Labor cost high

Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] see Figure 1-4 As shown, a beam side formwork opening device includes a bidirectional drilling mechanism, a handle 1 and a support rod.

[0022] Wherein, the bidirectional drilling mechanism includes a main body 2, a driver 5, an eccentric gear 9, a concentric gear 10, a shaft roller 11, a spring 14, a flat plate 17 and a bidirectional drill. The two-way drilling mechanism can realize opposite sequential drilling, and its specific structure is as follows:

[0023] The main body 2 is a square shell structure and is provided with a first chute 22 on its top or bottom surface. A vertical plate 20 is provided in the inner cavity of the main body 2. The vertical plate 20 is provided with a chute that is flush with the first chute 22. The second chute 21;

[0024] The driver 5 is a driving motor, and the driver 5 is fixedly arranged on the end face opposite to the end ...

Abstract

The invention discloses a beam side formwork trepanning device which comprises a bidirectional drilling mechanism, a handle and a supporting rod. The bidirectional drilling mechanism comprises a main machine body, a driver, an eccentric gear, a concentric gear, a shaft roller, a spring, a flat plate and a bidirectional drilling device. The bidirectional drilling mechanism can drill holes in sequence in the opposite direction. The handle is connected with the main machine body and used for holding and controlling the bidirectional drilling mechanism. The supporting rod is fixed to the bottom of the main machine body and used for supporting the bidirectional drilling mechanism. The characteristic that the eccentric gear can change the moving track of the driven concentric gear is ingeniously utilized, the shaft roller moves left and right in the main machine body through the driver, the eccentric gear, the concentric gear and the spring, the shaft roller drives the flat plate to move left and right on the main machine body, finally, left-right movement of the bidirectional drilling device is achieved, and trepanning operation is conducted on formworks on the two sides of a beam in sequence. The method has the advantages that the operation is convenient; the labor cost is reduced, and the working hours are saved; the working efficiency is improved, and the construction period is shortened; and the forming effect is good, and screw rods can easily penetrate to reinforce the side formworks of a beam.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a beam side formwork opening device. Background technique [0002] In the process of building construction, the reinforcement of the beam side formwork usually adopts the method of drawing rods, so after the formwork is completed, it is necessary to open holes in the beam side formwork. At present, there is no specialized machine for beam side formwork opening. In the actual construction process, workers often lie on the formwork and use hand drills and special drills to open holes. Not only is the operation inconvenient, the forming effect is poor (the same group of holes is prone to inconsistent high and low positions), and the work efficiency is low. Labor cost high. Contents of the invention [0003] The purpose of the present invention is to provide a beam side formwork opening device in view of the existing technical status, which is suitable for...
