Abstract

The utility model relates to a cast-in-place wet seam template hoist device of bridge, including a double round of handcart, the interval of two walking wheels of double round handcart is greater than the width of the wet seam of bridge, installs a small-size hoist engine on the double round handcart, and a spiral shell section of thick bamboo is connected to the lifting rope lower extreme of small-size hoist engine. Through hoist engine installation and transfer template, improved the mechanized construction degree of wet seam of bridge, be favorable to improving efficiency of construction and quality, reduce construction safety risk.

Description

Bridge cast-in-place wet seam template hoist device

Technical Field

The utility model belongs to the technical field of the bridge construction, a construction of the cast-in-place wet seam of bridge is related to, concretely relates to hoist device to mounted position from the underbridge with wet seam template.

Background

The upper structure of the continuous beam bridge mostly adopts a construction process of prefabricating and assembling, namely, beam bodies are prefabricated in advance in blocks in a prefabricating field and transported to the site for assembling, seams are reserved among the beam bodies of each block section, the beam bodies are connected into a whole by adopting cast-in-place concrete pouring seams, and the seams are wet seams.

The wet joint is long, the square amount is small, the thickness is thin, and the template dosage of unit volume is large. At present, the construction method generally includes that a formwork is lifted up from the ground by iron wires from a bridge manually, a tie bar is fixed at the bottom of a wet joint, after concrete pouring is completed and certain strength is achieved, the tie bar is detached, and the formwork falls on the ground. The existing method has the disadvantages of high labor intensity of constructors, low construction efficiency, difficult positioning during template installation, time and labor consumption when the height difference between a bridge floor and the ground is large, and poor construction safety.

Disclosure of Invention

The utility model aims at providing a special bridge cast in situ wet joint template hoist device reduces constructor intensity of labour for the construction progress improves the construction security.

The technical scheme of the utility model as follows:

the utility model provides a wet seam template hoist device of bridge cast-in-place which characterized in that: the double-wheel trolley comprises a double-wheel trolley, wherein the distance between two walking wheels of the double-wheel trolley is larger than the width of a wet joint of a bridge, a small winch is installed on the double-wheel trolley, and the lower end of a lifting rope of the small winch is connected with a screw cylinder.

The utility model discloses simple structure, convenient to use through hoist engine hoist and mount and transfer template, has improved the mechanized degree of construction of wet seam of bridge, is favorable to improving efficiency of construction and quality, reduces construction safety risk.

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a schematic structural view of a screw barrel;

fig. 3 is a schematic view of a connecting structure of the die plate and the screw cylinder.

Detailed Description

As shown in fig. 1, the utility model discloses a double round handcart 1, the interval of two walking wheels 2 of double round handcart is greater than the width of the wet seam of bridge, installs a small-size hoist engine 3 on the double round handcart, and a spiral shell section of thick bamboo 5 is connected to 4 lower extremes of lifting rope of small-size hoist engine.

As shown in fig. 2, one end of the screw cylinder 5 is provided with a lifting ring, and is connected with a lifting rope 4 of a winch through the lifting ring; the other end of the screw cylinder is provided with an internal thread.

As shown in fig. 3, for the cooperation the utility model discloses use, along the fixed 3 vertical screw rods 7 of template longitudinal centerline equidistance on wet seam template 6, the length of screw rod should be greater than the height of wet seam, and a middle screw rod is located the template center for with the spiral shell spiro union. Each screw is sleeved with a PVC pipe 8. The diameter of the PVC pipe is larger than that of the screw barrel, so that the screw barrel can move up and down in the PVC pipe.

As shown in fig. 1 and 3, the utility model discloses during the construction, two walking wheels 2 of double round handcart 1 stride in the wet seam 9 both sides of bridge, promote the handcart and remove the construction department along wet seam, start hoist engine 3 and relax lifting rope 4, make the screw tube 5 flagging to ground from wet seam, with screw rod 7 spiro union in the middle of screw tube 5 and template 6. Tightening a hoisting rope of the winch, lifting the template to the bottom of the wet joint to be tightly attached to the bottom surface of the beam slab, temporarily fixing the two bolts at the two ends and a support preset at the top of the wet joint, taking down the screw cylinder, temporarily fixing the middle bolt and the support, and pouring wet joint concrete. After the concrete reaches certain intensity, the screw cylinder is connected with the middle bolt, the template is placed on the ground through the winch, then the screw cylinder is retracted, and the trolley is pushed to move to the next construction position.

Claims

1. The utility model provides a wet seam template hoist device of bridge cast-in-place which characterized in that: the double-wheel trolley comprises a double-wheel trolley, wherein the distance between two walking wheels of the double-wheel trolley is larger than the width of a wet joint of a bridge, a small winch is installed on the double-wheel trolley, and the lower end of a lifting rope of the small winch is connected with a screw cylinder.
