After the beam side template and the beam are separated, because the action of gravity can freely fall, but the direction that hardly controls and drop, when the beam side template drops, owing to there is spacing brace 15 effect, the beam side template can be along the landing of roof beam plane direction to heavier one side to using spacing brace as the demarcation point, and can directly not topple over along the direction of perpendicular to roof beam plane, because there is the fender of L type gag lever post in the outside, we just so can control the direction that the template dropped, avoid hindering the people.
The invention also provides a beam side template dismantling method realized by adopting the beam side template dismantling device (hereinafter referred to as the device), which mainly comprises the following steps:
step 1: the device tip is inserted between the beam side template and the beam.
The tip of the device is in the shape of an oblique opening, the tip is plugged between a beam side template and a beam, the straight section is attached to the beam, and the oblique opening section is attached to the beam side template.
Step 2: the first pull rod 6 is pulled down and clamped into the first clamping hole 14.
Because just when beginning, the laminating of concrete beam and roof beam side form is still better, and the device pointed end can't insert too deeply, when inserting between roof beam side form and the roof beam back, pull down first acting as go-between 6, first acting as go-between 6 pulling first 7 downstream of acting as go-between, the pulling force makes receipts wire loop 3 drive first horizontal umbelliform gear 4 and rotates through the cardboard, first horizontal umbelliform gear rotates and drives first oblique umbelliform gear 4 and rotate, first oblique umbelliform gear rotates and makes first flexible ejector pin 2 extension, promotes first sled 1 and opens, utilizes the concrete beam to make roof beam side form and concrete beam gradually separate as the fulcrum.
And step 3: and (4) loosening the first wire pulling rod, returning the first wire pulling rod, and repeatedly pulling down the first wire pulling rod.
After the first wire drawing rod 6 is loosened, the first pry plate 1 can retract under the action of the joint force of the beam side template and the beam, the force drives the first oblique umbrella-shaped gear and the first horizontal umbrella-shaped gear to rotate reversely, and the first wire drawing rod returns to the initial position.
At the moment, partial holes exist between the beam side template and the concrete beam, the tip of the device can be inserted deeper, and when the device cannot be inserted continuously, the steps 2 and 3 are repeated until the first prying plate 1 penetrates into the beam side and exceeds the external corner.
And 4, step 4: and pulling down the second wire pulling rod 9 to be clamped in the second clamping hole 13.
And (3) opening the second prying plate 8 by using the principle of the step (2) as a fulcrum, prying the whole beam side template by using the lever principle, and enabling the beam side template to fall off from the beam side, thereby avoiding the occurrence of corner collapse of the external corner of the concrete beam.
And 5: spacing bracket 15 blocks beam side template
After the beam side template and the beam side are separated, the direction of falling is difficult to control due to the fact that gravity can fall freely, when the beam side template falls, the beam side template can slide to the heavier side by taking the support as a boundary point due to the effect of the support, and therefore people can be prevented from being injured by controlling the direction in which the template falls.
The method is simple and convenient to manufacture and implement, scientific and reasonable, can avoid the quality hidden danger and the installation hidden danger caused by the traditional beam-side template dismantling method, can be popularized and applied to dismantling the beam-side templates in a large scale, and has a good use prospect.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
