The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in the attached drawings 1-6, the utility model comprises an arc plate 1 which is placed in front and back, wherein the opening of the arc plate 1 is downward, and the front end surface and the back end surface of the arc plate 1 are provided with first grooves 2 along the circumferential direction; the arc-shaped plate 1 is provided with an L-shaped deck chair 3 which is placed in front and back, the front end and the back end of the turning part of the L-shaped deck chair 3 are respectively hinged with a connecting plate 4, and the other end of each connecting plate 4 can slide in the first groove 2 and can be fixed at a certain part of the first groove 2.

In order to fix the L-shaped deck chair 3 at a certain position of the first groove 2 conveniently, one end of the connecting plate 4, which is not hinged with the L-shaped deck chair 3, is provided with an inward bulge, the bulge can slide in the first groove 2, the bulge part is provided with a through hole 6 in the front-back direction, the bottom surface of the first groove 2 is uniformly provided with a plurality of blind holes 5, and a long rod 7 is inserted into the blind holes 5 through the through hole 6 to fix the L-shaped deck chair 3 at a certain height on the arc-shaped plate 1.

In order to ensure safety, the long rod 7 is an L-shaped rod, the front end and the rear end of the L-shaped deck chair 3 are fixedly provided with baffle plates 8, the outer end of the flat rod of the L-shaped rod is inserted into the blind hole 5 through the through hole 6, and the vertical end of the L-shaped rod is arranged on the inner side of the baffle plate 8, so that the L-shaped rod cannot be pulled out of the blind hole 5; after the horizontal section of the L-shaped rod is inserted into the blind hole 5 through the through hole 6 on the connecting plate 4, the vertical section of the L-shaped rod is rotated and is clamped into the inner side of the baffle plate 8, so that the L-shaped rod cannot be loosened from the blind hole 5 due to vibration and the like, and the safety of workers sitting on the L-shaped deck chair 3 is guaranteed.

In order to adjust the distance between the chair back of the L-shaped deck chair 3 and the arc-shaped plate 1, a plurality of second grooves 9 are arranged on the arc-shaped plate 1, and two abdicating notches which are symmetrical back and forth are arranged on the seat plate of the L-shaped deck chair 3; the workman sits when L shape deck chair 3 in the both legs can be placed two and steps down in the breach, the both feet are trampled in second recess 9 formation with convenient application of force in the 1 vertically cross-section of arc, when workman's arm is longer, can be with trampling at second recess 9 formation with 1 vertically cross-section of arc for the point of exerting oneself, the torsional spring effect in order to confront connecting plate 4 of pitching backward, the angle between the back of the chair that makes L shape deck chair 3 and arc 1 diminishes, and then the distance grow of the first half and the inverted arch that make workman's truck, conveniently carry out the construction.

In order to ensure safety and shock absorption, a spring shock absorber 10 is fixed at the lower end of a seat plate of the L-shaped deck chair 3, and the bottom shape of the spring shock absorber 10 is attached to the arc-shaped plate 1; when the construction is finished, at first the workman will resume perpendicular position with the truck, and the bumper shock absorber of bottom shape and the laminating of arc 1 avoids the workman to resume the position and causes vibrations too fast this moment, guarantees simultaneously that L shape deck chair 3 can only rotate between the back-bending position and horizontal position, and can not have the position that leans forward, prevents that the workman from producing on L shape deck chair 3 that the position that leans forward causes danger.

In order to enhance the comfort of the worker during lying on the back, the chair back of the L-shaped deck chair 3 is arc-shaped; the arc-shaped chair back is attached to the upper trunk of a human body, so that the waist of the human body can be well supported, and the fatigue of constructors is reduced.

When the special-shaped inverted arch construction machine is used, firstly, the L-shaped reclining chair 3 slides to a certain position of the arc-shaped plate 1 along the first groove 2, and when a constructor sits on the L-shaped reclining chair 3 at the position, the hand position can operate an inverted arch part needing construction; at the moment, after the horizontal section of the L-shaped long rod 7 is inserted into the blind hole 5 through the through hole 6 on the connecting plate 4, the vertical section of the L-shaped rod is rotated and clamped into the inner side of the baffle plate 8, so that the L-shaped rod cannot be loosened from the blind hole 5 due to vibration and the like, and the safety of workers sitting on the L-shaped deck chair 3 is ensured; constructor tramples on the second recess 9 on the arc 1 can climb up arc 1 and sit on L shape deck chair 3, constructor's two legs are put in two notches of stepping down of L shape deck chair 3, the foot is stepped on in second recess 9 and the convenient application of force of arc 1 vertically cross-section, constructor's foot is with trampling the cross-section that forms with arc 1 vertically at second recess 9 as the power point, the torsional spring effect of countervailing connecting plate 4, make the back of the chair and the angle between arc 1 of L shape deck chair 3 grow or diminish, and then make the first half of workman's truck and the distance grow or diminish of inverted arch, and then finely tune the distance between constructor arm and the inverted arch, with the construction operation and the construction tool of adaptation difference arm length and difference, the constructor of convenient difference carries out different construction operations.

The utility model discloses still set up spring damper 10, spring damper 10 installs the seat lower extreme at L shape deck chair 3, when the construction finishes, at first the workman will resume perpendicular position with the truck, the bumper shock absorber of bottom shape and 1 laminatings of arc avoids the workman to resume the position and leads to the fact vibrations too soon this moment, guarantees simultaneously that L shape deck chair 3 can only rotate between the back position of leaning on and horizontal position, and can not have the position of leaning forward, prevents that the workman from producing the position of leaning forward on L shape deck chair 3 and causing danger.

It is worth noting that the L-shaped reclining chair of the utility model needs two reclining chairs which are respectively placed on the left half side and the right half side of the arc-shaped plate for use; preferably, the constructor wears a helmet or a transparent mask to prevent stones or dust on the inverted arch from falling to cause damage to the constructor when the constructor lies on the L-shaped deck chair 3 for construction.
