Description

Structure for stairway handrail

The setting of hand rail is common in stair and balcony, and its main member have hold up pipe (handrail), several are connected to the arm (railing) of holding up pipe bottom and can be connected in the bend pipe of managing side company for changing angle; To adopt wooden person in early stage system be many to this hand rail member again, and only higher and application life is not long because of the wooden cost that is provided with, therefore visible now person makes with metal tube; Though about commonly use hand rail that metal tube makes can improve wooden railing cost height and application life weak point problem, yet because the structure setting of its combined member is not perfect, so, have time-consuming and inconvenient shortcoming and still exist at the construction fit on; For example:

(1): its fit on, must arrive first the gradient that stair are measured in construction place, thereafter, arrive the bend pipe of produce in factory special angle again, after making, pipe to be curved takes again to construction place combination, cause on the assembling process rather numerous and diverse.

(2): it holds up the combination between pipe and arm, and welding is adopted by general system, and is welded on that construction is gone up and not convenient, and has not good effect to making up to see outside the back.

The inventor is in view of if after designing a kind of can the measurement to construction place, the hand rail that can at once assemble, engineering time is shortened, and if to holding up the binding of Guan Yuzhi pipe component, the comparatively fit structure of facility can be provided, can further improve the practicality of metal system hand rail; Be with under this design basis, the inventor after repeatedly actual tests is improved, be have can be satisfactory the utility model produce.

The main purpose of the utility model is to provide a kind of must not measure the gradient of stair and hand rail structure that construction place that arrives can be assembled according to the slope of stairs in advance, and mat holds up the adaptation setting of the tube wall of pipe, and is quite easy with the mount that can reach hand rail.

According to hand rail structure of the present utility model, it includes two bend pipes, holds up pipe and several can be connected to the members such as railing of holding up the pipe bottom.But wherein hold up pipe socket bend pipe.And railing system can be taken as straight tube, protecting wire net, and stair ground also can be fixed in its bottom.Two bend pipes are that curved arc becomes the hollow tube of special angle respectively.Wherein bend pipe two ends respectively form less pullover of caliber; This is pullover to socket-connect with holding up within the pipe footpath; The two ends of another bend pipe are respectively the mouth of pipe of an end and the pullover fit mutually of above-mentioned bend pipe; And an end also form caliber than I for holding up pullover that pipe box connects.The rotatable adjustment of socket of mat two bend pipes, and change the tube angulation of holding up of linkings is in order to the bend pipe of various construction sites and hold up pipe to assemble.

Caving inward bottom the tube wall of holding up the pipe appropriate location is formed with groove, and the side of this groove extends tube wall and is formed with wing plate.Wherein groove is in the socket of railing top, and wing plate is connected mutually with railing.

When the stair of holding up pipe and bend pipe socket to be arranged to turn 90 degree or commentaries on classics face place, plane, building, can utilize single two ends to have pullover bend pipe and be connected and hold up pipe to be embodiment.

Now conjunction with figs. is described in detail as follows:

(31) groove (32) wing plate

(33) breach (4) straight tube

(5) protecting wire net (6) rivet

Please refer to Fig. 1 to shown in Figure 3, the utility model mainly includes two bend pipes (1) (2), holds up pipe (3) and several can be connected to the members such as railing of holding up pipe (3) bottom, wherein just Fig. 1, embodiment shown in Figure 2, railing system is made of straight tube (4), protecting wire net (5); Each member is made by metal material, when utilizing aluminium material to make as if desire, also can cooperate indoor decoration and personal like, utilizes plating mode to add color in the surface.

Bend pipe (1) (2), it is respectively the hollow tube that curved arc becomes special angle, wherein the two ends of a bend pipe (1) respectively form caliber less pullover (11), the two ends of another bend pipe (2) be respectively an end can with the mouth of pipe (21) of the tight fit of pullover (11) external diameter, and the other end also forms pullover (22) with pullover (11) identical caliber, the mouth of pipe (21) end of mat bend pipe (2) is sleeved on one of bend pipe (1) end pullover (11), can form the socket of pipe shape so that bend pipe (1) (2) but between mat rotation and change the socket angle.

Hold up pipe (3), system be internal diameter can with pullover (11) (22) of bend pipe (1) (2) blank pipe body among the fit mutually, the appropriate location tube wall bottom system of Yu Fuguan (3) caves inward and is formed with a groove (31), and the side of this groove (31) extends tube wall and is formed with a wing plate (32) (but also dual-side all extend be provided with wing plate); The bottom system of straight tube (4), protecting wire net (5) is fixed in ground, and its top is can cooperate to be enclosed in the groove (31) of holding up pipe (3), consult shown in Figure 3, straight tube (4) cooperates by the top holds up the wing plate (32) of pipe (3) to locate, but the system mat rivet (6) be riveting in wing plate (32), and protecting wire net (5) but the top equally also mat closing-up in wing plate.

The utility model is being implemented in the combination, see also Fig. 1, embodiment shown in Figure 2, this embodiment system is installed in the turning that stair are 180 degree, socket-connecting at first by two bend pipes (1) (2), and according to the gradient of stair, the angle of adjusting between two bend pipes (1) (2) (only must be omited swivel elbow, the difference in height at bend pipe two ends is changed), Deng bend pipe (1) (2) angle that two ends form and stair change the bend pipe of place formation involutory after, two bend pipes (1) (2) phase riveted can be fixed; Afterwards, cooperate the pipe (3) of holding up cut suitable length to distinguish pullover (11) (22) of socket two bend pipes (1) (2), and can utilize equally rivet in addition riveted fix; At last, the utility model mat is held up the setting of groove (31) Yu the wing plate (32) of pipe (3), can be really and socket rapidly fixedly straight tube (4) and protecting wire net (5), and constitute a firm and refined hand rail.

Please consult shown in Figure 4ly again, the utility model is desired to be installed in when turning the corner, stair Cheng Lou plane of 90 degree, only mat bend pipe (1) two ends pullover with hold up pipe (3) two mutual sockets to fix, and the socket of cooperation straight tube and protecting wire net gets final product under the pipe (3) in holding up again; Other consults shown in Figure 5, and the pipe (3) of holding up of the utility model is provided with, and also can utilize instrument to make its inner breach (33) that forms from the formation of groove (31), and distolateral pullover (11) (22) of breach (33) and bend pipe (1) (2) are connected by this.

The structure setting of the utility model can reach following effect on the implementation:

(1) founds meter first of mat two bend pipes (1) (2) socket, the constructor only must take each member to construction place, can adjust the angle of two bend pipes or single bend pipe according to the gradient or the angle of construction place, hold up the socket riveted of pipe (3) with cooperation, promptly finish bend pipe and hold up assembling between pipe.Quite convenient and rapid in construction.

(2) mat is held up and is founded meter first of pipe (3) tube wall recessed trench (31) and the wing plate (32), can form hold up between pipe (3) and railing (straight tube becomes protecting wire net) directly fixing, and this fixing operation is quite rapidly with certain, can simplify the process of railing construction sequence, and have and commonly use the better outward appearance of welding manner, demonstrate fully the practical value that the utility model is promoted effect.
