Description

Concrete marsh-gas pond wooden model

The utility model relates to a kind of template of making the concrete marsh-gas pond.

For a long time, people use Sheet Steel Form always when making the concrete marsh-gas pond, this Sheet Steel Form is made up of polylith rectangle arc surface wallboard and polylith sphere wedge shape vault plate, all uses bolt and connection piece affixed between per two blocks of wallboards and the per two blocks of vault plates, makes it to connect into an integral body.Also need during deposit concrete to divide up and down two-layer intersection withstand two blocks of relative on circumference wallboards, with a upper end of withstanding the vault plate, 8-16 root top, in case mold integral gross distortion or collapse with 4-6 root top tube.This Sheet Steel Form weight is big, cost is high, take a lot of work during mounting cost: the about 4600-6500 of the Sheet Steel Form cost unit that a cover is made 6-12 cubic meter of concrete methane-generating pit, 4-6 skillfully the frock mould is consuming time needs 100-120 minute approximately.

Task of the present utility model be to provide a kind of in light weight, cost is low, the concrete marsh-gas pond wooden model of time and labour saving is installed.

Task of the present utility model is finished like this: it is except that having wallboard and vault plate, also has skewer bar, support and a supporting plate in order to supporting arch top board upper edge isometric with wallboard, support is placed on the center of the circle that wallboard surrounds, supporting plate is placed on the support, and the vault plate is striden and is placed between wallboard and the supporting plate.

Wallboard can by wooden a tree, used in making timber for boats bar and the rectangle wood strip is affixed forms.The vault plate also can by wooden a tree, used in making timber for boats bar and the wedge shape wood strip is affixed forms.Support can adopt side's " well " font support of four vertical rods.Supporting plate can be an annular plank, also can be the yoke plate that two semi-round ring shape planks is fused with hinge.

Because the utility model has skewer bar, support and a supporting plate in order to supporting arch top board upper edge isometric with wallboard, can simply and easily wallboard and vault plate be supportted respectively surely and hold, thereby can be connected with connection piece without bolt between per two blocks of wallboards and the per two blocks of vault plates, thereby can reduce dress mould and striking time and workload widely.Owing to use producing wood, thereby weight reduction widely, reduce cost.The about 700-1000 of the utility model wooden model cost unit that one cover is made 6-12 cubic meter of concrete methane-generating pit, two skilled frock moulds only need 10 minutes.

Be elaborated with drawings and Examples below.

Fig. 1 is a vertical profile synoptic diagram of the present utility model.Fig. 2 is the sectional view along A-A line among Fig. 1.

With reference to accompanying drawing, the utility model by the ligneous rectangle arc surface of polylith wallboard 1, the ligneous sphere wedge shape of polylith vault plate 2, one form in order to support 4 and a supporting plate 5 of supporting arch top board upper edge with the isometric skewer bar of wallboard 3, one.

Wallboard 1 can be made with the monoblock timber of 60 mm thick, but so waste is expected, 8 nail joints of rectangle wood strip or bonding fastening the forming of two straight wooden a tree, used in making timber for boats bars 6 of the most handy 40-45 mm thick, 2-3 root circular arc wood a tree, used in making timber for boats bar 7 and polylith 15-20 mm thick.12 nail joints of wedge shape wood strip or bonding fastening the forming of the last circular arc wood a tree, used in making timber for boats bar 10 of the vertical wooden a tree, used in making timber for boats bar of two isometric arcs of vault plate 2 usefulness 40-50 mm thick 9, a weak point, long following circular arc wood a tree, used in making timber for boats bar 11 and the big or small increasing or decreasing of polylith, 15-25 mm thick.Support 4 can adopt the three-legged support of three vertical rods, but preferably adopts side's " well " font support of four vertical rods, and it is formed by four vertical rods 13 and 14 nail joints of several piece arm-tie, and it not only firmly but also had easily torn the frame form removal open.Supporting plate 5 can be an annular plank, also can be with two semi-round ring shape planks, the 16 hinged yoke plates that fuse with hinge 15.

During construction of marsh gas tank, earlier with at the bottom of the concrete placement pond, cheat 100 millimeters places of native germ wall again in the distance pond, wallboard 1 of the present utility model all is close to installation successively, and be seated with skewer bar 3, form a drum, then with the full bay wall of concrete casting, lay " well " font support 4 again at the center, pond, on support, place yoke plate supporting plate 5 with the hinged two semi-round ring shape planks of hinge, at last the vault plate is striden successively and be placed between wallboard 1 and the supporting plate 5 and be close to mutually, round shape rib made from fragment of brick or with timber or semi-cylindrical shaped rib 17 are placed on and block the aperture that the vault plate surrounds on the supporting plate 5, promptly available concrete placement pond vault.
