Detailed Description
As shown in fig. 1-2, a portable tunnel waterproof plate lap-joint construction platform is arranged in a side ditch 2 of a tunnel and comprises two bipods and an overhanging platform plate 5 which horizontally extends from the tops of the two bipods to a tunnel lining;
here, the use of the bipod and the overhanging platform plate 5 has many considerations: one of the two-leg frame structure is that a large opening is formed between the two-leg frame and the overhanging platform plate 5, so that the utility model can be pushed along the side ditch 2 without being blocked by the waterproof plate and other members reserved at the bottom of the tunnel; secondly, the two foot rests can be propped against the wall of the side ditch 2, so that the whole platform cannot shake left and right when in use on the premise of the casters 33; it is third in making the utility model discloses collapsible to adapt to the narrow construction scene in the tunnel.
The bipod sets up in the gutter 2 along 2 extending direction intervals in the gutter, and every bipod includes a shore at the fixed landing leg 31 of the wall root department of side wall 1 and a shore and keeps away from the movable landing leg 32 on the gutter wall of side wall 1 at the gutter 2, and the top of movable landing leg 32 is connected with the top of fixed landing leg 31 is articulated, and the articulated shaft of junction is on a parallel with 2 extending direction settings in the gutter.
Fixed landing leg 31 top is fixed with the flange pole 4 that the level set up and extend to the tunnel wall, and flange pole 4 is higher than the setting of the reservation reinforcing bar at 1 top of boundary wall, and the border of encorbelmenting landing slab 5 respectively with two 4 fixed connection on the board limit pole.
In this embodiment, the caster 33 is a self-locking universal wheel, and a cover is provided outside the caster 33, and a cushion for preventing the waterproof board on the side wall 1 from being scratched is further wrapped outside the cover of the caster 33 of the fixed leg 31.
4 one ends shore of board limit pole is on the tunnel lining wall and the other end is fixed on fixed landing leg 31 top, and 4 tip parcels of board limit pole shore on the tunnel lining wall have the cushion, leave the space that is used for avoiding the waterproof board between stiffener 6 and side wall 1. The end of the plate edge rod 4 is propped on the lining wall, so that the stability of the platform is further improved, but the waterproof plate on the wall can be broken through, and therefore, a cushion needs to be wrapped on the plate edge rod 4.
A reinforcing rod 6 is vertically arranged between the fixed supporting leg 31 and the plate edge rod 4, and two ends of the reinforcing rod 6 are respectively fixedly connected with the fixed supporting leg 31 and the plate edge rod 4. Stiffener 6 has formed the triangular structure with fixed landing leg 31 and flange limit pole 4, promotes the firm degree of the platform board 5 of encorbelmenting, avoids encorbelmenting the end downwarping of platform board 5.
Fixed leg 31, activity landing leg 32, flange limit pole 4 and stiffener 6 are the steel pipe, and the landing slab 5 of encorbelmenting is the steel sheet net, 6 both ends of stiffener respectively with fixed leg 31 and 4 welded connection of flange limit pole, flange limit pole 4 respectively with fixed leg 31 and 5 welded connection of the landing slab of encorbelmenting.
A locking device for locking the included angle between the fixed leg 31 and the movable leg 32 is arranged between the two. Here, the hinge shaft between the fixed leg 31 and the movable leg 32 can be a bolt, the locking device is a nut on the bolt, and the locking device can fix the included angle between the fixed leg 31 and the movable leg 32, thereby enabling the utility model discloses also can regard as the dolly outside the gutter 2 and push away, conveniently transport.
The application provides a use method of a portable tunnel waterproof plate lap joint construction platform, which comprises the following steps:
the method comprises the following steps: the utility model is put into the side ditch 2, and two foot rests are stretched to prop against the two sides of the side ditch 2;
step two: the utility model is pushed to the using position, the caster 33 is locked, and the construction is started;
