Description

Disc socket joint formula steel cat ladder

Technical Field

The utility model relates to a building engineering construction technical field especially indicates a disc socket joint formula steel cat ladder.

Background

The construction of urban public building projects is very fierce, and in the construction of large public buildings, the main structure has more parts with larger height difference, which brings great difficulty to constructors in the aspects of operation passage, safe passage and fire control passage. In actual construction of a construction site, the ladder stand is erected by adopting traditional fastener type steel pipes mostly, the erection mode is random, stress at the joint of the fasteners is unreasonable, and the overall safety, stability and reliability of the ladder stand are poor.

Disclosure of Invention

To not enough among the above-mentioned background art, the utility model provides a disc socket joint formula steel cat ladder has solved the relatively poor problem of cat ladder stability, reliability among the prior art.

The technical scheme of the utility model is realized like this:

the utility model provides a disc socket joint formula steel cat ladder, includes pole setting and horizontal pole, and the horizontal pole tip is equipped with C type bayonet socket be used for with the pole setting joint, be equipped with in the pole setting with C type bayonet socket complex joint portion, wear to be equipped with the bolt in C type bayonet socket and the joint portion.

Furthermore, the clamping portion is a disc horizontally arranged on the vertical rod.

Further, the thickness of the disc is matched with the opening width of the C-shaped bayonet.

Further, the bolt is a steel wedge bolt.

Furthermore, wedge holes for the insertion pin to pass through are formed in the disc and the C-shaped bayonet.

Furthermore, a plurality of wedge holes are formed in the disc.

Furthermore, the lower end of the vertical rod is provided with a bearing platform type sleeve matched with the upper end of the vertical rod.

The utility model has the advantages that: the socket type fixing mode of the utility model is more strict than the connection of a fastener type, the framework is more strict, the socket position of the disc is the central stress, the stress is reasonable, the node is reliable, and the integral rigidity of the component is high; the installation and disassembly are convenient, stable and reliable, a plurality of work types are not needed to be matched, and the construction efficiency is high.

Drawings

In order to illustrate the embodiments of the present invention more clearly, the drawings that are needed in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the description below are only some embodiments of the present invention, and that other drawings can be obtained by those skilled in the art without inventive work.

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

fig. 2 is a schematic structural view of the vertical rod of the present invention;

fig. 3 is a schematic structural view of the cross bar of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1-fig. 3, a disc socket joint formula steel cat ladder, pole setting 1 including two parallel arrangement, two be connected with horizontal pole 2 between 1 pole in pole setting, 2 tip of horizontal pole are equipped with C type bayonet socket 21 and are used for with 1 joint in pole setting, be equipped with in pole setting 1 with C type bayonet socket 21 complex joint portion, C type bayonet socket 21 is connected the back with joint portion joint, wears to be equipped with bolt 3 in C type bayonet socket 21 and the joint portion.

Further, the clamping portion is a disc 12 horizontally arranged on the vertical rod 1, and the disc 12 and the vertical rod 1 are coaxially arranged. The C-shaped bayonet 21 is clamped on the upper side and the lower side of the disc 12.

Further, as shown in fig. 2 and 3, wedge holes for the insertion pin 3 to pass through are formed in the disc 12 and the C-shaped bayonet 21, so that the insertion pin 3 is vertically inserted into the disc 12 and the C-shaped bayonet 21, and the connection between the disc 12 and the C-shaped bayonet 21 is reinforced.

Further, the bolt 3 is a steel wedge bolt.

By using the socket type fixing mode, compared with the fastener type connection, the framework is stricter, and the socket position of the disc is stressed as the center, so that the stress is reasonable and reliable.

Embodiment 2 differs from embodiment 1 in that the thickness of the disc 12 is matched with the opening width of the C-shaped bayonet 21, so that the C-shaped bayonet 21 is clamped on the disc 12 more stably.

Embodiment 2 is different from embodiment 1 in that, as shown in fig. 2, a plurality of wedge holes are uniformly distributed on the disc 12 at equal angles, so as to facilitate the steel wedge type plug pin to penetrate through the disc 12 and the C-shaped bayonet 21, and more than one C-shaped bayonet 21 and plug pin can be arranged on the disc 12 in a matching manner.

Embodiment 3, which differs from embodiment 1 in that the lower end of the vertical rod 1 is provided with a bearing platform type sleeve 11 which is matched with the upper end of the vertical rod 1, as shown in fig. 2. When the upright stanchions 1 are short in height, a plurality of upright stanchions 1 can be inserted and connected through the bearing platform type sleeves 11, the bearing platform type sleeves 11 are produced by adopting a cold extrusion process, and the bearing capacity is 3 times that of common steel pipes.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
