Abstract
The utility model provides a novel cat ladder structure, includes U type steelframe, the through-hole has been seted up to U type steelframe both ends department, install the spring bolt on the through-hole, the cover is equipped with the external screw thread cover on the U type steelframe both ends, the cover is equipped with the internal thread cover on the external screw thread cover, the one end fixed connection of internal thread cover is on the steel sheet. The problems that the template is difficult to dismantle after the main body structure is formed in the existing construction, the positioning distance is uneven and the like easily occur are solved.
Description
Technical Field
The utility model relates to a municipal works field especially relates to a novel cat ladder structure.
Background
At present, in modern buildings, the objects are large in quantity and multifunctional, and in order to meet the requirements of fire fighting, civil air defense and the like, the crawling ladder is often arranged at the mouths of a fire pool, a civil air defense project, an explosion-proof cable well, a diffusion chamber and the like. The installation of conventional cat ladder adopts the cat ladder built-in fitting directly to bury in the concrete member often, often appears the locating distance inequality in the major structure work progress easily, major structure shaping back template demolishs the big scheduling problem of the degree of difficulty, influences the engineering progress.
Disclosure of Invention
An object of the utility model is to provide a novel cat ladder structure to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a novel cat ladder structure, includes U type steelframe, the through-hole has been seted up to U type steelframe both ends department, install the spring bolt on the through-hole, the cover is equipped with the external screw thread cover on the U type steelframe both ends, the cover is equipped with the internal thread cover on the external screw thread cover, the one end fixed connection of internal thread cover is on the steel sheet.
Preferably, a clamping groove is formed in the inner portion of the internal thread sleeve, and the U-shaped steel frame is fixed to the clamping groove through a spring bolt.
Preferably, the length of the spring bolt is twice of the diameter of the U-shaped steel frame.
The utility model has the advantages that:
1. the internal thread cover welds on the steel sheet during construction, buries in advance in concrete or wall body and spills the internal thread cover, demolishs the template after concrete or wall body solidify, blocks spring bolt and external thread cover in order to fix U type steelframe, has solved the big scheduling problem of the template demolishment degree of difficulty after the major structure shaping in the current construction.
2. The steel plate can be put into after the distance of good built-in fitting of manual measurement in the construction to solve and appear the uneven scheduling problem of location interval easily.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-6, a novel ladder stand structure, including U type steelframe 1, the through-hole has been seted up at U type steelframe 1 both ends, installs spring bolt 2 on the through-hole, and spring bolt 2's diameter is less than the diameter of through-hole, and spring bolt 2's length is twice of U type steelframe 1 diameter, and external screw thread cover 3 overlaps on U type steelframe 1, and the one end welding of internal screw thread cover 5 is on steel sheet 4, and the other end revolves soon and twist on external screw thread cover 3, and spring bolt 2 blocks on draw-in groove 7 simultaneously. The internal thread sleeve 5 is welded on the steel plate 4 when in specific use, then is buried in concrete or a wall body and leaks the internal thread sleeve 4, demolishs the template after concrete or the wall body is solidified, and the spring bolt 2 and the external thread sleeve 3 are blocked in order to fix the U-shaped steel frame 1, so that the problems of high difficulty and the like in demolishment of the template after the main body structure is formed in the existing construction are solved.
The working principle is as follows: firstly bury internal thread 5 on steel sheet 4 on wall body 6, and spill internal thread cover 5, then cover two internal threads 5 with supporting plastics to prevent that the material sediment from falling into in internal thread cover 5, take off supporting plastics after wall body 6 solidifies, press at this moment spring bolt 2 and wear the U shaped steel frame 1 to the external screw thread cover, then revolve the external screw thread cover 3 and twist on internal thread cover 5, spring bolt 2 card is gone into in draw-in groove 7 simultaneously.
Claims (3)
