Abstract
The invention relates to a method for loading a bridge support frame in a lower-suspension way, which is characterized by comprising the following steps: (1) producing a prefabricated part; (2) paving guide rails between upright rods of the bridge support frame after construction of the bridge support frame, and installing the prefabricated part on the guide rail; (3) hoisting a first fabricated part on the bridge support frame with a wire rope or a guide chain or an electric hoist and ensuring the height between the lower surface of the first prefabricated part and the ground is 50-100 mm, and so forth, hoisting a second prefabricated part on the bridge support frame till the design load weight of the bridge support frame is achieved; and (4) disconnecting the prefabricated part and the bridge support frame when the bridge support frame load reaches the design requirement, and landing the prefabricated part on the guide rail, then pulling the prefabricated part out of the bridge support frame, and hoisting away the prefabricated part with a crane to the next construction segment for use continuously. The invention has the characteristics of high efficiency, good safety and reusability of loading materials and prefabricated parts.
Description
Technical field
The invention belongs to civil engineering, bridge engineering field, relate in particular to a kind of hanging method that bridge support frame is loaded down.
Background technology
During for assurance bridge board pour concrete, its bridge support frame does not sink, and often need earlier bridge support frame be loaded after bridge support frame has been set up, and after meeting the demands, just can carry out nation and wire-tie fluid concrete.The method that traditional bridge support frame loads is to adopt the method for artificial heap sand bag, and this method is simple, convenient.But also there are the following problems: 1, bridge support frame is generally higher, artificial heap sand bag labour intensity height; 2, the characteristics of bridge support frame preloading are that circuit is long, area is big, and artificial heap sand bag efficient is low; 3, the proportion of sand is little, and therefore, the sand bag takes up an area of many, needs the height height of heap, and the preloading difficulty strengthens, and is dangerous; 4, because of the height height of heap, a large amount of people is at high-altitude heap sand bag, and is dangerous; 5, progress is slow, can prolong the time at envelope dealings, and is unfavorable to resident trip; 6, gapped between the sand bag, load tonnage and measure inaccurate.
Summary of the invention
The object of the present invention is to provide a kind of efficient height, safety good, add the reusable hanging method that bridge support frame is loaded down of loading.
To achieve these goals, technical scheme of the present invention is: the following hanging method that bridge support frame is loaded is characterized in that it comprises the steps:
1) makes prefabricated units 1, prefabricated units are block, be fixed with second suspension hook 7, the 3rd suspension hook 9 in the upper surface of prefabricated units 1, second suspension hook that second suspension hook 7 is positioned on the upper surface of prefabricated units 1 is installed groove 6, the 3rd suspension hook 9 is positioned at the 3rd suspension hook on the upper surface of prefabricated units 1 and the upper end of groove 8, the second suspension hooks 7, the 3rd suspension hook 9 is installed all is lower than the upper surface of prefabricated units 1; The soffit of prefabricated units 1 is provided with first roller 2, second roller 3, the 3rd roller 12, the 4th roller 13, first roller 2, second roller 3, the 3rd roller 12, be equipped with annular groove on the 4th roller 13, first roller 2 and second roller 3 are positioned on the same axis, the 3rd roller 12 and the 4th roller 13 are positioned on the same axis, first roller 2, second roller 3, the 3rd roller 12, the 4th roller 13 lays respectively at each self-corresponding roller and installs in the groove 14, first roller 2, second roller 3, the 3rd roller 12, the soffit of prefabricated units 1 is all protruded in the lower end of the 4th roller 13; First suspension hook that is fixed with in the leading flank of prefabricated units 1 on the leading flank that first suspension hook, 5, the first suspension hooks 5 are positioned at prefabricated units 1 is installed groove 4; The 4th suspension hook that is fixed with in the trailing flank of prefabricated units 1 on the trailing flank that the 4th suspension hook 11, the four suspension hooks 11 are positioned at prefabricated units 1 is installed groove 10;
2) after bridge support frame has been constructed, on the ground between the vertical rod 17 of bridge support frame, lay first guide rail 15, second guide rail 16 also extends to bridge support frame outer (effect of guide rail is the turnover of being convenient to prefabricated units), with lifting appliance (as crane) first prefabricated units are hung in first guide rail 15, the top of second guide rail 16, then first prefabricated units are fallen, first roller 2 on first prefabricated units, second roller 3 drops on first guide rail 15, the 3rd roller 12, the 4th roller 13 drops on second guide rail 16, again first prefabricated units are pushed between the vertical rod 17 of bridge support frame, with wire rope or lead chain or electric block 18 hitches (locking) second suspension hook 7, the 3rd suspension hook 9, with wire rope or lead chain or electric block 18 is hung first prefabricated units on the cross bar 19 of bridge support frame, the soffit of first prefabricated units height overhead is 50～100mm then; And the like, again second prefabricated unit hung on the cross bar 19 of bridge support frame, until the design loaded weight that reaches bridge support frame;
3) after bridge support frame loads and reaches designing requirement, remove being connected of cross bar 19 (promptly untie wire rope or lead chain or electric block 18) of prefabricated units and bridge support frame, prefabricated units are dropped on first guide rail 15, second guide rail 16, then, prefabricated units are pulled out (bridge support frame comprises the vertical rod 17 of bridge support frame and the cross bar 19 of bridge support frame) from bridge support frame; Use lifting appliance (as crane) that prefabricated units are hung away again, be transported to next construction section and continue to use.
The material of described prefabricated units is a steel concrete, or cast iron, or cast steel; Prefabricated by existing conventional method.
The length of described prefabricated units is 1.0～2.5m, and wide is 0.5～1.2m, and height is 0.5～1.5m.
Versatility for the heap(ed) capacity that guarantees prefabricated units can be designed to prefabricated units the different kind of height, makes up then or single use, thereby can satisfy the requirement of the different heap(ed) capacity of each engineering.
The present invention has following beneficial effect:
1, the present invention loads the sand bag and changes prefabricated units into, and artificial heap sand bag changes lifting appliance into, installs adding loading, and installation process is simple, has shortened the duration greatly; And because prefabricated units are installed on bridge support frame below, and distance overhead is very near, has avoided prefabricated units to load on bridge support frame and repeating up and down of producing transported, and has further shortened the duration greatly, has reduced cost; Duration only is 1/15～1/10 of artificial preloading; Have the high characteristics of efficient.
2, the prefabricated units of hanging distance overhead is very near, has prevented to add loading and has put improper or connect loosening and falling of producing causes casualties, and security performance is good.
3, the installing/dismounting prefabricated units make things convenient for, save time, and have reduced the big machinery operation, and by manually cooperating and can finish with small-sized machine, cost is low.
4, adding loading is prefabricated units, accurate measurement.
5, prefabricated units take up an area of few than great.
6, loading quantity is few, and the duration shortens, and reduces the envelope traffic time.
7, adding loading (being prefabricated units) can reuse, and highly versatile can use for a long time, meets the policy requirements of recycling economy, has embodied energy-conservation and environmental protection.
