Background technology
In Hydraulic and Hydro-Power Engineering construction building field, the Diversion Tunnel in power station is an interim engineering construction, and engineering has very high requirement to compactness, planeness and the fineness of lining concrete, and often the duration very urgent, under the premise that security is guaranteed, should simplify the engineering of lining cutting as far as possible.The concrete lining cutting layering of Diversion Tunnel is divided into base plate, side wall, crown three parts, the concrete lining cutting most critical of crown wherein, be related to the duration can complete on schedule, can quality guarantee.And the key procedure of the concrete lining cutting of crown is exactly formwork erection, and it plays a part very important, so reasonably the design of falsework is particularly important.
China is the supporting way that adopt full hall falsework at present more, supporting form has full wood to support, also having steel wood to support to mix uses, but the problem that exists is that material usage is big, the dismounting difficulty is big, the formwork erection time is long, disposable input cost height, potential safety hazard is many etc., and can not guarantee concrete pouring quality.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of Diversion Tunnel crown concrete lining cutting steel form support, has overcome the shortcoming that adopts full hall falsework, can have enough to meet the need use repeatedly, install and remove convenient and swift, and can save material, and guaranteed construction quality, strengthened the construction safety degree.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of Diversion Tunnel crown concrete lining cutting steel form support, the bottom that is installed on the crown support of Diversion Tunnel crown is connected with many Eight characters support tops, and many Eight characters support bottoms are connected with many form braces that are fixedly installed in the Diversion Tunnel side wall.
The many Eight characters support first halves are reinforced by at least one stull.
The crown support is made up of a Pin support and the 2nd Pin support, locks by alignment pin between a Pin support and the 2nd Pin support, and fastens by cross, and the lateral surface of crown support is welded with steel plate.
The one Pin support and the 2nd Pin support adopt steel pipe and reinforcing bar welding to make.
The Eight characters supports into " eight " font, and the bottom of crown support is connected by perfect after-sales service with many Eight characters support tops.
Be connected by perfect after-sales service between Eight characters support and the stull.
The Diversion Tunnel crown concrete lining cutting steel form support that the utility model provides, beneficial effect is as follows:
1, formed by crown support and Eight characters support, and the steel form support of reinforcing by stull, the employing combined type connects, easy accessibility, simple in structure, overcome the shortcoming that adopts full hall falsework, below steel bracket, had enough spaces to be open to traffic, be conducive to side wall and crown lining cutting cross-operation simultaneously.
2, crown support, Eight characters support and stull adopt perfect after-sales service to connect, and adopt the cross card connection between the two Pin supports of crown support, have effectively guaranteed globality and the stability of steel bracket, have also made things convenient for the dismounting work in later stage.
3, making material model is few, making is simple, and can have enough to meet the need use repeatedly, has saved cost, has reduced input.
4, the saving of labor, save time, the material saving, easy construction, safe and reliable; Can freely assemble, flexible operation, of a tightly knit structure, firm; Install rapidly, improved workmanship and work efficiency, improved working environment.
5, the steel plate of crown support outer side edges welding makes the crown support firmly is placed on vertical channel-section steel of Diversion Tunnel side wall, and next step combination that is beneficial to the steel form support is installed.
6, the effect that strengthens stability and globality, increase rigidity and intensity has been played in stull to the steel form support.
7, adopt the alignment pin locking between a Pin support and the 2nd Pin support, and adopt cross to fasten, played the effect that strengthens crown support globality and stability.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model crown support;
Fig. 3 is the enlarged drawing at Figure 1A place.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of Diversion Tunnel crown concrete lining cutting steel form support, the bottom that is installed on the crown support 2 of Diversion Tunnel crown 14 is supportted 3 tops with the many Eight characters and is connected, and the many Eight characters support 3 bottoms and are connected with the many form braces 8 that are fixedly installed in Diversion Tunnel side wall 15.
The many Eight characters support 3 first halves and reinforce by at least one stull 4.
Crown support 2 is made up of a Pin support 2-1 and the 2nd Pin support 2-2, adopt alignment pin 1 locking between the one Pin support 2-1 and the 2nd Pin support 2-2, and adopt cross card 7 fixing, to play globality and the stable effect that strengthens crown support 2, the lateral surface of crown support 2 is welded with steel plate 12, make the crown support firmly is placed on vertical channel-section steel of Diversion Tunnel side wall that next step combination that is beneficial to the steel form support is installed.
The one Pin support 2-1 and the 2nd Pin support 2-2 adopt steel pipe 10 and reinforcing bar 11 welding to make.
3 one-tenth " eight " fonts of Eight characters support, the bottom of crown support 2 is supportted 3 tops with the many Eight characters and is connected by perfect after-sales service 6.
