Abstract

The utility model relates to a moulded cast part stair which comprises steps and a guard rail, wherein, the steps are composed of foot boards and connecting keels, which are connected with each other by multistage alpha and omega to form the stair, and each of the connecting keels is an integral type casting, wherein, one end of which is provided with a threaded upright post 1 and the other end of which is provided with a threaded open pore 3 or a same threaded upright post; a connecting beam 3 is arranged between the both ends, and the upright post is raised out of the plane of the connecting beam. Positioning holes 6 and 7 are opened on the side walls of the upright post and the open pore of the connecting keel, and the connecting keels are connected with each other through the mutual screwing-in of the threaded both ends and are fixed through screw bolts which are screwed into the positioning holes. The utility model has the advantages of free assembly and combination, few structural members, simple structure and convenient processing and assembly, and the utility model can adapt to various occasions, has more transformation and can satisfy desirability for users in different levels.

Description

Module foundry goods formula stair

Technical field

The utility model relates to the stair that are used on the building, particularly a kind of module foundry goods formula stair.

Background technology

Along with the continuous progress and the development of society, people's living standard is greatly improved, and compound building and villa appear in people's the life more and more, and be more and more nearer from the common people.Simultaneously, people are also more and more fastidious to indoor decoration and layout.Stair between compound building and the villa levels are the important component parts in whole house, should require to adapt with whole decorated style in the building and owner.Yet the stair that are used for compound building and villa now are normally machine made, finish at building and form and pay owner, often arbitrarily conversion, migration and change man-hour in the lump.There are the problems referred to above too in the stair that lead to " roof garden ".In fact situation, occasion or the requirement that by own wish stair is set in the life is a lot.At these problems, once the someone proposed the design of " but assembly combined stair ", but these combined staircase parts are many, the assembly unit engineering is loaded down with trivial details, member processing technology complexity, so the cost height, can not satisfy instructions for use fully.

Summary of the invention

It is firm and solid simple and be easy to process module foundry goods formula stair with assembly unit that the purpose of this utility model provides a kind of member.

Said module foundry goods formula stair, comprise ladder and guardrail, ladder by pedal be connected keel and form, multistage head and the tail are held in the mouth the formation stair mutually, it is characterized in that: said connection keel are a kind of monolithic foundry goods, and an end has a threaded column, and the other end is provided with a threaded perforate or is similarly threaded column, be a tie-beam between the two ends, column protrudes from the tie-beam plane.

On the sidewall that connects keel column and perforate, be provided with locating hole, connect keel and screw in mutually by threaded both ends each other and be connected, fix by the bolt that screws in the locating hole.

Said connection keel cross section be " H " shape, " L " shape,

Or it is "T"-shaped.Said module foundry goods formula stair, the column and the tie-beam that connect keel are hollow.

The utlity model has can free assembling combination characteristics, member is few, and is simple in structure, has to be convenient to the advantage of processing and assembling, and can adapt to multiple occasion, and more conversion is arranged, and can satisfy different levels user's hope.

Description of drawings

Fig. 1 is a kind of connection keel of the utility model and step configuration structural representation;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 connects keel and pedal and guardrail combining structure schematic diagram;

Fig. 4 is the overall structure schematic diagram;

Fig. 5, Fig. 6, Fig. 7 are other several connection keel schematic cross-sections.

Among the figure: 1-column, 2-tie-beam, 3-perforate, 4-pedal, 5-guardrail, 6-locating hole, 7-bolt.

Embodiment

Connecting keel casts the most firm and solid easy with cast steel.If the screw thread on its column is an internal thread, then the screw thread in the perforate just should be external screw thread.If two ends are the column form, then wherein on the column perforate must be arranged.Be connected keel and be connected being connected the end and can adding a flat board of keel and aspect with end being used to connect first of bottom and upper strata, to increase the firmness that stair are connected with aspect.When the stair height is 3 meters, conduct oneself with dignity about 500 kilograms with stair that cast steel material is made.Connect also other materials making such as useable glass steel, steel concrete of keel.Guardrail can be according to user's different requirements and arbitrarily configuration of hobby with pedal.

Fig. 5～Fig. 7 connects other several forms of implementation of keel.Connect and adjust connection angle by spiral form, make the easy advantage of assembly unit that the utlity model has by its sidewall locating hole bolt.

Claims

1, a kind of module foundry goods formula stair, comprise ladder and guardrail, ladder by pedal be connected keel and form, multistage head and the tail are held in the mouth the formation stair mutually, it is characterized in that: said connection keel are a kind of monolithic foundry goods, and an end has a threaded column, and the other end is provided with a threaded perforate or is similarly threaded column, be a tie-beam between the two ends, column protrudes from the tie-beam plane.

2, as the said module foundry goods of claim 1 formula stair, it is characterized in that: on the sidewall that connects keel column and perforate, have locating hole, connect keel and screw in mutually by threaded both ends each other and be connected, fix by the bolt that screws in the locating hole.

3, as the said module foundry goods of claim 1 formula stair, it is characterized in that: said connection keel cross section be " H " shape, " L " shape,
