Abstract
The utility model discloses a mechanical type muffjoint vertical ladder, including cat ladder U type spare, embedded iron spare, connecting sleeve and connecting filament head, embedded iron spare imbeds at the premises convex female connection head has on the embedded iron spare bare surface, the connecting filament head is twisted soon female connection is overhead, the both ends of cat ladder U type spare be equipped with the line with the screw thread silk tooth that the connecting filament head is opposite will through the connecting sleeve the connection of cat ladder U type spare is fixed the connecting filament is overhead. The utility model discloses ladder easy operation, simple to operate, construction method are easily mastered, and construction speed is fast, have solved traditional vertical ladder stiff end and built -in fitting welded connection among the building engineering, and the easy corrosion of welded connection department is rotted, and dangerous hidden danger is great, and the accident scheduling problems such as taking place the conflagration easily that aerial work welding construction danger coefficient is big and spark that easy welding produces splashes.
Description
Technical field
This utility model relates to construction and installation technical field, particularly relates to a kind of mechanical sleeve and connects vertical ladder.
Background technology
Along with China's economy and the fast development of urban infrastructure, cat ladder is gradually widely used in various buildings or structures as a kind of affiliated facility, the such as ventilating shaft etc. of city municipal administration hoistway, inspection shaft, tunnel, chimney, cistern, steelmaking furnace and large public building.At present, mostly the construction method of conventional metals cat ladder is by embedded iron parts on concrete component, later stage by the connected mode of welding cat ladder welded fixing structurally, though using the mode being welded to connect to have the superiority of himself, but in the tall and slender structure that some are large-scale, in the such as structures such as steelmaking furnace, chimney, needing to carry out work high above the ground, welding quality hardly results in guarantee, and execution conditions are more complicated, work high above the ground operation inconvenience in narrow space, field welding joints qualification rate is low；Welding simultaneously still belongs to work with torches, and the danger of falling object from high altitude, fire incident easily occurs.The fixing end of vertical ladder is welded to connect with built-in fitting, and need to eliminate rust mopping process at the place of being welded to connect, and after process after certain time limit, weld still easy-to-rust rots, and dangerous hidden danger is bigger.
Utility model content
Technical problem to be solved in the utility model is, shortcoming for above prior art, propose a kind of mechanical sleeve and connect vertical ladder, solve the fixing end of tradition vertical ladder in architectural engineering to be welded to connect with built-in fitting, it is welded to connect place's easy-to-rust to rot, dangerous hidden danger is relatively big, and big and that easily welding the produces spark of high-rise working welding procedure danger coefficient splashes and is susceptible to the problems such as accident such as fire.
In order to solve above-mentioned technical problem, the technical solution of the utility model is achieved in the following ways: provide a kind of mechanical sleeve to connect vertical ladder, including the U-shaped part of cat ladder, embedded iron parts, branch sleeve and connecting filament head, described embedded iron parts is embedded in building, described embedded iron parts exposed surface has the female screw connection of protrusion, described connecting filament head is screwed on described female screw connection, the two ends of the U-shaped part of described cat ladder are provided with the screw thread silk tooth that lines is contrary with described connecting filament head, by branch sleeve, U-shaped for described cat ladder part is fastened on described connecting filament head.
The technical scheme that this utility model limits further is: aforesaid mechanical sleeve connects vertical ladder, and the U-shaped part of described cat ladder is made up through bending of round steel.
Further, aforesaid mechanical sleeve connects vertical ladder, and described cat ladder U-shaped part surface has galvanizing coating, prevents corrosion, impact safe handling.
The beneficial effects of the utility model are as follows: the vertical ladder that (1) mechanical sleeve connects is simple to operate, easy for installation, construction method is easily grasped, and speed of application is fast, and each joint cat ladder set-up time is only about 1.5 ~ 2min, is substantially shorter the duration, cost-effective；
(2) the vertical ladder that mechanical sleeve connects is when being applied to the towering structure engineering such as cylinder, chimney, operator can with dress with, it is not necessary to such to welding procedure, can load after the cooling such as needing；
Antirust, fireproof coating smeared in processing space the most by the most all components, and on-the-spot directly rustless steel sleeve connection is assembled, does not carries out the working procedures such as touch-up paint again, cost-effective；
(4) during sleeve connection, decreasing a large amount of work with torches, reduce the arc light impact on surrounding enviroment, some mass defects such as the undercut that simultaneously can avoid producing during welding, overlap, non-penetration, construction quality, safety obtains powerful guarantee, and social benefit is high；
(5) avoiding the fixing end of vertical ladder to be welded to connect with built-in fitting, need to eliminate rust mopping process at the place of being welded to connect, and after process, after certain time limit, weld still easy-to-rust rots, and dangerous hidden danger is bigger.

Detailed description of the invention
Below this utility model is described in further detail:
Embodiment 1
A kind of mechanical sleeve that the present embodiment provides connects vertical ladder, structure is as shown in Figure 1 to Figure 3, including the U-shaped part of cat ladder 1, embedded iron parts 2, branch sleeve 3 and connecting filament head 4, the U-shaped part of cat ladder is made up through bending of round steel, cat ladder U-shaped part surface has galvanizing coating, embedded iron parts is embedded in building, embedded iron parts exposed surface has the female screw connection 5 of protrusion, connecting filament head is screwed on female screw connection, the two ends of the U-shaped part of cat ladder are provided with the screw thread silk tooth that lines is contrary with connecting filament head, by branch sleeve, U-shaped for cat ladder part is fastened on connecting filament head.
It is similar to steel bar stress sleeve connection that the vertical ladder mechanical sleeve of the present embodiment connects its operation principle; U-shaped for cat ladder part is connected directly between on embedded iron parts by the mode i.e. using branch sleeve to connect; embedded iron parts needs to be processed making by design drawing requirement in advance; the threaded connector of protrusion is had on embedded part; as when concrete placings; need to be exposed at outside template, it should be noted that the protection of screw during construction, it is to avoid occur to pollute and destroy.When being attached sleeve connection, the screw thread on embedded part and cat ladder should be processed into positive and negative silk, connect time, it is only necessary to tighten sleeve both can be connected firm.
Above example only illustrates technological thought of the present utility model; protection domain of the present utility model can not be limited with this; every according to the technological thought that the utility model proposes, any change done on the basis of technical scheme, within each falling within this utility model protection domain.
