Fig. 2 is that the A-A of this utility model Fig. 1 is to sectional front view.
Detailed description of the invention
Below in conjunction with accompanying drawing, concrete truth mode of the present utility model is elaborated.
By Fig. 1, 2 provide, this utility model includes sliding formwork body, slideway, pulley, pulley support and sleeper, sliding formwork body lower bottom part is equipped with pulley support 7, equipped with pulley 8 on pulley support, pulley is contained on sleeper 10 slideway 9 above, sliding formwork body is made up of the advancing slip die body 19 that the cross section that structure is identical is doorframe shape and rear sliding formwork body 20, it is connected mutually in convex-concave with before rear sliding formwork body 20 after advancing slip die body 19, and link together through walking push cylinder 4, the structure of advancing slip die body or rear sliding formwork body is, the top ferrum 1 of cross cylinder 14 and crossbeam 3 front end is by being bolted together, through bolt 12 equipped with being connected the top ferrum 5-1 diagonal brace 11 linked together with the first post lower limb below crossbeam, first post lower limb connects the lower section of top ferrum 5-1 and is connected with hoist cylinder 6 top through bolt, hoist cylinder bottom connects top ferrum 5-2 equipped with the second post lower limb, second post lower limb connects ferrum 5-2 bottom, top equipped with the transverse direction walking push cylinder 4 being placed on pulley support 7, it is provided with steel plate 2 between outside and the body of wall 21 being made up of concrete 17 of hoist cylinder 6, steel plate upper end is externally provided with, in the upper cross wall face of body of wall, the cross-tie 18 linked together with steel plate, the straight wall of body of wall both sides, the cross wall on top is outer equipped with wall exterior sheathing 15, equipped with the screw mandrel 16 being perpendicular to wall exterior sheathing on wall exterior sheathing 15, 23 are supported equipped with oblique connection between screw mandrel 16 outer end and wall exterior sheathing 15, second post lower limb connects on the ferrum 5-2 of top equipped with the stull 13 being perpendicular to hoist cylinder 6.
In order to ensure result of use, described walking push cylinder 4 is four, is respectively placed in the top and the bottom inside two steel plates 2 in left and right, steel plate thickness 4mm; The linking in convex-concave of described advancing slip die body 19 and rear sliding formwork body 20, constitutes anti-concrete roof and is caving structure;
Described rear sliding formwork body rear end is equipped with two diagonal brace oil cylinders 22, and the piston rod of diagonal brace oil cylinder stretches out, and constitutes slip support abutment structure; Being connected with between described cross cylinder 14 end and the top ferrum 1 of corresponding crossbeam 3, the piston of cross cylinder stretches, and constitutes the width adjusting structure of sliding formwork body; Described hoist cylinder 6 is connected top ferrum 5-1 with the first post lower limb, the second post lower limb connects top ferrum 5-2 and connected by bolt, and hoist cylinder 6 piston stretches, and constitutes the height adjustment structure of sliding formwork body;
The body of wall edge that described advancing slip die body 19 front end concrete is made is inclined plane shape (namely concrete angle of repose is inclined plane shape), body of wall height 300mm.
By said structure it can be seen that this utility model sliding formwork by having bottom slideway 9, return pulley 8, pulley support 7, slideway 9 bottom front sliding formwork 19 and 20 liang of group sliding formworks of rear sliding formwork to spread sleeper 10, paving sleeper is the concrete floor built in advance and the high body of wall 21 of 300mm for 10 times. Two set sliding formworks are connected by four set walking push cylinder 4. The effect of front sliding formwork 19 is casting concrete 17, after its backform with rear sliding formwork 20 backform before concavo-convex section be concrete reach initial setting strength time, the transition region that template sliding is taken over from the past and set a new course for the future. This section can ensure that forward and backward sliding formwork supports smoothly transitting of concrete roof. The support concrete roof that the effect of rear mold is above-mentioned will not cave in, more supporting liftable individual prop follow-up roof supporting, it is ensured that perfectly safe. During sliding formwork, diagonal brace oil cylinder 22 works as bearing after stretching out.
Backform cross cylinder 14 of the present utility model and the top ferrum 1 of crossbeam 3 front end, be bolted, it is simple to installing/dismounting. In order to improve the rigidity of crossbeam, diagonal brace 11 is installed under crossbeam. Spreading 4mm steel plate 2 cross cylinder piston outside sliding formwork to stretch, the width of sliding formwork is adjustable. Equally, hoist cylinder 6 is connected top ferrum 5 bolt connection with post lower limb. When hoist cylinder 6 piston stretches, so that it may adjust the height of sliding formwork. The function of so two-way adjustment, sliding formwork is suitable for the gallery of different change section. Two sliding formworks close up can work as again together formwork jumbo use, get twice the result with half the effort.
The concrete 17 that reinforcing bar binding is complete, build reaches initial set. During sliding formwork sliding, the diagonal brace oil cylinder piston 18 of rear mold 20 stretches out support and works as bearing on ground, and walking oil cylinder 4 stretches out piston, promotes front one step pitch of sliding formwork 19 sliding. Now, by the concrete of the concavo-convex backform roof supporting of front sliding formwork 19. After sliding completes, rear mold 20 is regained by diagonal brace oil cylinder 18 and walking push cylinder 4, one step pitch of sliding formwork 20 sliding after drive, now, the embossed area of rear mold 20 closes up, the gallery that moved in circles construct, the wall exterior sheathing 15 of both sides be vertically by wall mould triangular support bracket bottom adjustment screw mandrel 16 regulate, meet vertical requirement pull bar 18 and lock.
In order to ensure the smooth sliding of gallery sliding formwork, when producing, the super instant coagulant shortening the presetting period can be added in concrete, improve concrete early strength. Concrete angle of repose bevel(l)ing is pressed in front sliding formwork 19 wall mould front end, and adopts the electronic demoulding, makes to produce a kind of steam between concrete and the template just built, serve the effect of lubricant, facilitate sliding formwork, it is ensured that continuous concreting, improve waterproof effect and the presentation quality of gallery. Interior wall side form by above-mentioned front end bevel(l)ing, wear the triangular support bracket of return pulley, regulate screw mandrel, slideway, hydraulic moving, support system etc. and just can be used for the interior wall side form slding form operation of underground civil defense engineering, purposes is wide, and economic and social benefit is notable.
