Abstract

The utility model relates to a ropeladder used for the lateral tensioning of a T-shaped girder, which comprises a platform, a crawling ladder, two inclined struts, two pothooks, a plurality of idler wheels and a platform guard railing, wherein the platform is formed by connecting a plurality of cross-braces in a grid form; the lower end of the crawling ladder is connected with the edge of the rear end of the platform; the two ends of the two inclined struts are respectively connected to the lower parts at the two sides of the crawling ladder and the front parts of the two sides of the platform; the two pothooks are respectively in an inverted-L shape, the rear end of an upper cross bar is connected to the upper end edge of the crawling ladder, a vertical bar is located at the rear end of the crawling ladder, the idler wheels are arranged on the bottom surface of each cross bar at intervals, and the platform guard railing is arranged on the edge of the front end of the platform. Due to the ropeladder used for the lateral tensioning of the T-shaped girder, a constructor can stand on the ropeladder to laterally tension the T-shaped girder and the like without auxiliary construction of large-scale mechanisms during bridge construction, so that the construction speed is fast and the construction cost is low. In addition, the device has the advantages of simple structure, light weight, low price, convenience in operation, and the like; and operation can be easily completed by only two or three constructors, so that fewer constructors are needed.

Description

T beam transverse stretching hanging ladder

Technical field

The utility model belongs to bridge construction special equipment technical field, particularly relates to a kind of T beam transverse stretching hanging ladder.

Background technology

When need crossing over the river in railway, the road paving process, just must build a bridge, many at present employing T beams are as the superstructures of bridge, and the T roof beam structure need carry out transverse stretching to it after establishing completion, compress and operation such as end-blocking.Explain that for non-cast-in-place continuous T beam above-mentioned these operations often need the constructor to accomplish in the high-altitude, in the past generally by the big machinery auxiliary construction.Because the translational speed of big machinery is slow, so inefficiency, and running cost is high, and potential safety hazard is big, and required constructor is many.

Summary of the invention

In order to address the above problem, the purpose of the utility model is to provide a kind of simple in structure, in light weight, easy to operate T beam transverse stretching hanging ladder.

In order to achieve the above object, the T beam transverse stretching hanging ladder that provides of the utility model comprises platform, cat ladder, two diagonal braces, two hooks, a plurality of roller and Terrace prevention hurdles; Wherein platform is to be latticed connection and to be constituted by many stulls; Cat ladder vertically is provided with, and its lower end links to each other with the back edge of platform; The two ends of two diagonal braces are connected to two side lower parts of cat ladder and two forequarters of platform; Two hooks are L shaped, and the rear end of its cross tube is connected the upper end-face edge of cat ladder, and montant is positioned at the rear of cat ladder, and standoff distance is equipped with a plurality of rollers on the bottom surface of every cross bar; The Terrace prevention hurdle then is vertically mounted on the front edge of platform.

Be equipped with plank on the described platform or between the platform on the adjacent T beam transverse stretching hanging ladder.

The T beam transverse stretching hanging ladder that the utility model provides can make the constructor in bridge construction, stand above that the T beam is carried out transverse stretching, compresses and operation such as end-blocking, and need not by the big machinery auxiliary construction, thus speed of application to reach construction cost soon low.In addition, that this device has is simple in structure, in light weight, cheap, be convenient to advantage such as operation, and only needs just light complete operation of two or three constructor, so required constructor is few.

Description of drawings

The T beam transverse stretching hanging ladder structural perspective that Fig. 1 provides for the utility model.

Fig. 2 is the T beam transverse stretching hanging ladder structure side view shown in Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the T beam transverse stretching hanging ladder that the utility model provides is elaborated.

Like Fig. 1, shown in Figure 2, the T beam transverse stretching hanging ladder that the utility model provides comprises platform 6, cat ladder 4, two diagonal braces 5, two hooks 2, a plurality of roller 1 and Terrace prevention hurdles 8; Wherein platform 6 is to be latticed connection and to be constituted by many stulls 7; Cat ladder 4 vertically is provided with, and its lower end links to each other with the back edge of platform 6; The two ends of two diagonal braces 5 are connected to two side lower parts of cat ladder 4 and two forequarters of platform 6; Two hooks 2 are L shaped, and the rear end of its cross tube is connected the upper end-face edge of cat ladder 4, and montant is positioned at the rear of cat ladder 4, and standoff distance is equipped with a plurality of rollers 1 on the bottom surface of every cross bar; Terrace prevention hurdle 8 then is vertically mounted on the front edge of platform 6.

Be equipped with plank on the described platform 6 or between the platform 6 on the adjacent T beam transverse stretching hanging ladder.

Existing utilize T beam transverse stretching hanging ladder that the utility model provides that the T beam is carried out transverse stretching, compresses and the process of operation such as end-blocking describes the constructor:

At first utilize manual work that T beam transverse stretching hanging ladder is drawn to the T depth of beam; And two on it hooks 2 are hung on the T beam abutment wall 9; Make 1 contact of a plurality of rollers simultaneously on the end face of T beam abutment wall 9, constructor with belt then can be from cat ladder 4 down to platform can carry out stretch-draw on 6, compress and construction such as end-blocking.Both can adopt single T beam transverse stretching hanging ladder to construct during operation, two T beam transverse stretching hanging ladders also can be set in a segment distance, between the platform 6 on two T beam transverse stretching hanging ladders, lay plank simultaneously, can construct continuously like this.

Carry out secondary move a preceding constructor must be earlier from the cat ladder 4 to the T beam; Only move empty T beam transverse stretching hanging ladder then, to guarantee personal security, its less important affirmation roller 1 motion track place does not have foreign matter; Move in case influence it, stable back just can repeat aforesaid operations.
