Description
Technical Field
The utility model relates to a wall device is held up to safe cat ladder, and specifically speaking is an adjustable assembled safe cat ladder wall device.
Background
At present, when a high pier body of a bridge is constructed, more and more safety crawling ladders are used, the safety crawling ladders are simple in structure, safe and reliable, but poor in stability, and therefore, buttress walls are required to be arranged every 3-6 m and connected with the existing pier body structure to improve stability of the existing pier body, and traditional buttress walls are all adopted
The steel pipe utilizes fastener and safe cat ladder crossbeam to link to each other or adopts shaped steel and safe cat ladder mobile jib welding, and these two kinds of methods all have not little defect in the difficult and easy degree that still need the ann to tear open in the structural stress, and during general high mound construction, the counterfort spare of safe cat ladder needs a lot of. Therefore, the safety ladder needs an adjustable and assembled device with convenient installation and disassembly and safe and reliable structure.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of existence among the prior art, provide a rational in infrastructure, improve construction efficiency, reduce construction cost, to the great adjustable assembled safe cat ladder device of optimizing that has carried out of prior art of construction.
The technical scheme of the utility model is realized according to following mode:
an adjustable assembly type safe crawling ladder wall supporting device is composed of a device body, wherein the device body comprises an upper limiting unit, a lower limiting unit, a left attached vertical rod unit and a right attached vertical rod unit which are connected with the upper limiting unit and the lower limiting unit, each limiting unit is composed of a left limiting angle steel and a right limiting angle steel which are arranged in parallel, an end head corresponding to the middle of each limiting angle steel is welded with an end head sealing plate with a through hole respectively, a limiting tie bar penetrates through each through hole, and two ends of each limiting tie bar are provided with external threads for being screwed with nuts respectively; every is a set of adhere to pole setting unit for vertical setting be used for with the fixed pole setting of pier shaft looks, adhere to the upper and lower both ends of pole setting and be connected with another end of spacing angle steel respectively through the drawknot hook, with adhere to the main drawknot muscle in addition that the pole setting homonymy set up, main drawknot muscle is arranged in being connected the spacing angle steel in two sets of spacing units from top to bottom.
The drawknot hook is formed by a right-angled S-shaped structure.
The aperture of the through hole is matched with the outer diameter of the limiting tie bar.
The utility model has the advantages that:
the utility model discloses an adjustable assembled safe cat ladder parapet device compares with prior art, can effectively solve to different safe cat ladders parapet reform transform difficult, parapet and cat ladder connection security performance can't guarantee, ann tears open the cat ladder and parapet difficult problems such as the process is complicated, the device all can adopt existing material to process the preparation, to the load evenly distributed of safe cat ladder in the pole setting, easy operation, safe and reliable, and can reduce the construction input, improve the construction work efficiency.

Detailed Description
The following detailed description of the adjustable assembled safety ladder buttress device of the present invention will be made in conjunction with the following embodiments.
Referring to fig. 1, 2, 3, 4, the utility model relates to an adjustable assembled safety ladder climbing device, including upper and lower two sets of spacing units, and the left and right two sets of attached pole setting units that are connected with it, each set of spacing unit is formed by two spacing angle steels 2 that are arranged in parallel, the corresponding end in the middle part of the spacing angle steel 2 is welded with the end closing plate 3 with through hole respectively, spacing drawknot muscle 5 is worn to be equipped with by the through hole, the aperture of the through hole and the external diameter of spacing drawknot muscle 5 of this embodiment are set up in a matching way, namely when the aperture of through hole increases, the external diameter of spacing drawknot muscle 5 also increases with it, otherwise, it decreases; the two ends of the limiting tie bar 5 are respectively provided with an external thread, namely, the part penetrating through the hole of the end head sealing plate can be fixed by a nut, and the length of the limiting tie bar can be adjusted; each group of the attachment vertical rod unit comprises an attachment vertical rod 1 which is longitudinally arranged and is used for being fixed with a pier body 7, the upper end and the lower end of the attachment vertical rod 1 are respectively connected with the other end of a limiting angle steel 2 through a drawknot hook 4, and the drawknot hook 4 is formed by a right-angled S-shaped structure in the embodiment; and the main tie bar 6 is also arranged on the same side of the attached vertical rod 1, and the main tie bar 6 is used for fixedly connecting the limiting angle steels 2 in the upper and lower two groups of limiting units.
The preparation method of the utility model is as follows: firstly, welding the limit angle steel and the end head sealing plate into a whole, and then connecting the two limit angle steels by using a limit angle steel tie bar; connecting the limiting angle steel with the attachment angle steel by using a drawknot hook; and finally, the two groups of limiting angle steels are tied into a whole by using the main tie bars. A firm frame structure is formed, the ladder stand 8 is arranged to be firmly limited in the frame structure, and the purpose of stabilizing the safe ladder stand is achieved.
