Detailed description of the invention
Be applicable to a formwork system for large-scale deep trouth hole sty bed course, as shown in Figure 1 and Figure 2, this formwork system is the internal mold of falling truncated rectangular pyramids be made up of groove hole bottom cushion 1, Anti-floating reinforcing steel bar 2, template 5 and steel tube frame 7; Described groove hole bottom cushion 1 be positioned at bottom, groove hole, for supporting one piece of screeding concrete template of whole template system, described Anti-floating reinforcing steel bar 2 is embedded in bottom, groove hole and cheats bottom cushion 1 with groove and pours into a mould and be connected; Described steel tube frame 7 is made up of vertical, horizontal horizontal steel tube 71, vertical steel pipe 72 and reinforcing bridging steel pipe 73, fastener type steel pipe is adopted to set up into the shape of truncated rectangular pyramids between steel pipe, steel tube frame 7 is connected with Anti-floating reinforcing steel bar 2, described template 5 is inverted trapezoidal, be arranged on steel tube frame 7 formed four inverted trapezoidal inclined-planes outside, base is fixed on the bottom cushion 1 of groove hole, the fixing collar 3 of cheating on bottom cushion 1 at groove, having a concrete block 31 to form outside template 5.
Described Anti-floating reinforcing steel bar 2 adopts Φ more than 16 reinforcing bar to be bent into hollow.
Described template 5 adopts the thick above veneer of 15mm or a tree, used in making timber for boats wood.
The design principle being applicable to the formwork system of large-scale deep trouth hole sty bed course of the utility model is:
According to design size, the shape of dell, by setting up steel pipe support and template in the dell inside completing earthwork evacuation, form an internal mold of falling truncated rectangular pyramids, thus ensure that the blinding concrete of dell cliff slope disposablely can water the type of being pounded.
Wherein, the formwork system being applicable to large-scale deep trouth hole sty bed course of the utility model needs to calculate and design through internal force, according to groove hole the gradient, highly, size, form, calculate lateral pressure during slope casting and compacting of concrete, thus determine the spacing in length and breadth of formwork system steel pipe, step pitch and reinforce the setting of bridging, above-mentioned computational methods are known technologies, repeat no more herein.
Force principle, analysis:
The steel tube frame 7 being applicable to the formwork system of large-scale deep trouth hole sty bed course of the utility model is by forming to horizontal steel tube 71, vertical steel pipe 72 and reinforcing bridging steel pipe 73 in length and breadth, adopt fastener type steel pipe to set up into the shape of truncated rectangular pyramids between steel pipe, whole formwork system is set up shaping according to the shape that groove is cheated.
Wherein, the horizontal direction active force that template 5 transmits is born in length and breadth to horizontal steel tube 71, vertical steel pipe 72 bears template 5 and the vertical direction active force suffered by steel pipe support support body 7, and reinforce bridging 73 link level and vertical steel pipe, make support body form stable three-legged structure, increase the globality of support body.
The entirety of formwork system is as shown in Figure 4 stressed:
Wherein, N acts on the concrete lateral pressure in template 5, F
1, F
2be respectively concrete lateral pressure N and decompose the horizontal applied force of level and vertical direction and vertical upwards active force, G is gravity suffered by whole formwork system, F
3for the lower pulling force that Anti-floating reinforcing steel bar provides.
Take out left half of part and do force analysis, as shown in Figure 5:
Wherein, F
4for the vertical supporting power that steel pipe provides, F
5for the horizontal supporting force that steel pipe provides.
In figure, the horizontal supporting force F that steel pipe provides
5with the horizontal component F of N
1balance; Gravity G, lower pulling force F
3, vertical supporting power F
4three power are formed makes a concerted effort downwards, with the vertical upwards directed force F of N
2balance.
Like this, whole formwork system reaches internal force balance, thus guarantees the reliability of whole formwork system.
One as the utility model embodiment converts, and when deep trouth hole sty is not too large, also can arrange fixing collar 3 outside template 5.
As another conversion of the utility model embodiment, described fixing collar also can be built by laying bricks or stones without cement block, and directly builds a circle concrete as fixing collar 3.
