Description

A kind of new mortise and tenon type scaffold

Technical field

This utility model is related to a kind of scaffold, more particularly to a kind of new mortise and tenon type scaffold.

Background technology

Scaffold is that job site for operative and solves the various supports vertically and horizontally transporting and setting up, predominantly Workmen works up and down or perimeter security net is gone along with sb. to guard him and high-altitude installation component etc..Existing scaffold system mainly includes detaining Part formula, bowl fastening type, wheel button, disk button, spigot-and-socket and mortise and tenon type etc. are although every kind of scaffold has respective advantage, but tenon Fourth of the twelve Earthly Branches formula scaffold because its higher bearing capacity, preferable safety, faster handling speed and widelyd popularize.

Mortise and tenon type scaffold is mainly made up of the cross bar with tenon and the montant with fourth of the twelve Earthly Branches groove, due to little under the slot cross-section of the fourth of the twelve Earthly Branches Upper big, so mortise and tenon type scaffold has self-locking performance, there is not sliding in node, and Tenon scaffold node is that three face contacts are subject to simultaneously Power, compares with the scaffold of other contacts, can bear elevated pressures.Only cross bar need to be inserted the fourth of the twelve Earthly Branches of montant when it is installed Cross bar only need to be knocked out during dismounting by groove from bottom surface, and therefore mortise and tenon type scaffold is installed, dismounting is simple, speed of application is very fast.Though So there is above-mentioned substantial amounts of advantage in mortise and tenon type scaffold, but be different from the system of the scaffolds such as fastener as a force way, The connection of its brace and remainder is still continued to use fastener type and is connected, and makes mortise and tenon type scaffold can not independently become one completely System, to its promote and using make troubles victory impact；Although additionally, mortise and tenon type scaffold is in short transverse bearing capacity Very strong, but be short of in other direction bearing capacities.

Content of the invention

This utility model provides a kind of new mortise and tenon type scaffold for solving above-mentioned technical problem.

Technical solution adopted in the utility model is：A kind of new mortise and tenon type scaffold, including the cross bar with tongue-and-groove, Montant with stud receptacle, brace with least two tongue-and-grooves and for being connected described brace with described montant Forward connector；Described stud receptacle includes 4 tenons of socket and socket surrounding；Tongue-and-groove on described cross bar is enclosed within institute State outside the tenon of stud receptacle；Described forward adapting table and the through position that connector includes rotating against；Described adapting table It is provided with the tongue-and-groove for being connected with described stud receptacle, described through position is provided with the tenon for being connected with described brace Head.All of described tongue-and-groove upper end is provided with backplate, and described backplate top is domed, and lower end is seamlessly transitted with tongue-and-groove upper end.Forward The appropriate design of connector is so that the connection of brace and remainder can also be using mortise and tenon type so that mortise and tenon type scaffold Become an integral framework, be easy to promote and use.Additionally, backplate can protect tongue-and-groove and tenon junction to be subject to Exposure to Sunlight rain less Drench, mitigate mouldy (to wooden) or get rusty (to metal material), increase the service life, and so that installing/dismounting is more convenient.

Preferably, described center of protecting panel is provided with bearing pin；Described bearing pin top is provided with cap, and bottom is provided with convex edge；Described Center of protecting panel is provided with the through hole being available for that described bearing pin moves up and down, described tenon and described convex edge correspondence position be provided be available for described The through hole that convex edge passes through.When scaffold normally uses, bearing pin inserts tenon, limits the relative motion of tongue-and-groove and tenon, improves peace Full performance；During dismounting scaffold, pull up cap, convex edge is held backplate, contributed to the dismounting of cross bar.

Preferably, the distance between upper surface of tenon is more than described convex edge below the lower surface of described backplate and backplate Thickness.

Preferably, it is higher than corresponding tenon lower surface that described bearing pin is in described convex edge lower surface during extreme lower position, that is, Convex edge is located in tenon through hole, is directly used in the relative motion of limited tenon chase mortise head.

Preferably, described cap is domed, edge extends to outside described backplate, is easy to pull-up, and protects backplate to be subject to less Expose to the sun and rain.

This utility model has the advantages and positive effects that：Because this utility model is using as above technical scheme, forward The appropriate design of connector is so that the connection of brace and remainder can also be using mortise and tenon type so that mortise and tenon type scaffold Become an integral framework, be easy to promote and use.Additionally, backplate can protect tongue-and-groove and tenon junction to be subject to Exposure to Sunlight rain less Drench, mitigate mouldy (to wooden) or get rusty (to metal material), increase the service life, and so that installing/dismounting is more convenient.

Except this utility model described above solve technical problem, constitute technical scheme technical characteristic and by Outside the advantage that the technical characteristic of these technical schemes is brought, other technologies problem that this utility model can solve, technology The advantage that the other technical characteristics comprising in scheme and these technical characteristics are brought, makees into one hereinafter in conjunction with accompanying drawing Step detailed description.
