Description

Simple support frame for stair guardrail

Technical Field

The utility model relates to a supplementary apparatus is restoreed to the guardrail, concretely relates to simple and easy support frame of stair guardrail.

Background

To the stair guardrail of live time overlength in the residential quarter, through long-time wind-blown sun rain or moist air soaks and attacks, corrosion damage phenomenon always appears, for the safety of people's walk up and down stairs, can restore the guardrail. Generally, in the repairing process, after the whole stair section guardrail is cut, a newly manufactured guardrail is welded on an original stair base, or a new rod piece is manufactured after a damaged part of guardrail is cut and welded. There is a safety hazard in this process: 1. the base of the stair guardrail can be rusted, after the base is removed and embedded again, the newly poured concrete has a strength standard reaching period, and the guardrail welded on the original base can not achieve the safe bearing effect temporarily; 2. after the damaged guardrail is mainly stressed upright stanchion cut, the time for replacing the new member bar is made, and the transverse member bar of the handrail connected with the stressed upright stanchion can not play the safety role of the guardrail because of being suspended.

Based on above-mentioned drawback, the applicant wants to set up a support frame at stair guardrail restoration in-process, supports the guardrail horizontal pole through the support frame to avoid restoring guardrail pole setting in-process, the guardrail production after the cutting is emptyd, causes the potential safety hazard to constructor or pedestrian.

Disclosure of Invention

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide a simple structure, can support the guardrail at stair guardrail cutting repair process, improve guardrail repair process's security to can reuse's simple and easy support frame of stair guardrail.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a simple support frame for a stair guardrail is fixedly arranged at the side end of a stair and is characterized by comprising a telescopic vertical pipe and a stepping clamping and fixing seat which can be fixed at the outer side of a stepping, wherein the stepping clamping and fixing seat is arranged at the lower end of the telescopic vertical pipe and is connected with the telescopic vertical pipe; a plurality of guardrail cross rod clamping pieces are installed above the stepping clamping fixing seat and on the telescopic vertical pipe at intervals, one end of each guardrail cross rod clamping piece can be buckled with a cross rod of a stair guardrail, and the other end of each guardrail cross rod clamping piece is connected with the telescopic vertical pipe. Therefore, after the guardrail corrosion part is cut, the support frames can be correspondingly arranged on the cross rods on two sides of the cutting part, and one support frame supports the cross rod on one side. The length of the telescopic vertical pipe can be adjusted according to the height of the guardrail, so that the telescopic vertical pipe can be suitable for repairing guardrails with various heights. The guardrail horizontal pole holder that sets up can form the support to cutting back guardrail with the horizontal pole lock, simultaneously, restores the later stage at the guardrail and forms the support to the guardrail with the guardrail, and then increases the stability and the security of guardrail. In addition, the support frame is simple in structure, convenient to install and disassemble and capable of being repeatedly used.

Furthermore, the telescopic vertical pipe comprises an upper rectangular pipe and a lower rectangular pipe, the upper rectangular pipe is sleeved in the lower rectangular pipe, a threaded hole is formed in the upper end of the lower rectangular pipe, and a tightening bolt used for fixing the upper rectangular pipe in the lower rectangular pipe is sleeved on the threaded hole. Like this, go up the quarter bend and can follow down quarter bend direction of height and slide from top to bottom to adopt the tight bolt of top to fix on last quarter bend through the tight mode in top. The structure can meet the requirements of height adjustment and positioning of the telescopic rectangular pipe.

And the clamping force formed by the screw and the nut on the upper top plate and the lower bottom plate is larger, and the damage to the stepping can not be caused.

Furthermore, the outer side of the upper top plate is sleeved on the telescopic vertical pipe and can slide up and down along the length direction of the telescopic vertical pipe. Therefore, after the upper top plate can slide up and down, the distance between the upper top plate and the lower bottom plate can be adjusted, and the clamping device is suitable for various clamping distances.

Furthermore, an escape opening is arranged on the inner side of the upper top plate. Like this, when fixed roof, if meet the stand, the mouth of stepping down can provide one for the stand and put into the space, and it is more convenient to use.

Furthermore, two rubber pads are sleeved on each screw, one of the two rubber pads is tightly attached to the screw cap of the screw, and the other rubber pad is arranged below the screw cap and is tightly attached to the upper top plate. Like this, set up the rubber pad after, can effectively promote the nut and mark time between the laminating degree, simultaneously, to the nut certain protection that forms.

Furthermore, the guardrail cross rod clamping piece comprises a screw rod and a clamping head, the outer end of the screw rod penetrates through the telescopic vertical pipe and the inner side and the outer side of the mounting sleeve and then extends out of the mounting sleeve, the inner end of the screw rod is sleeved with the clamping head, and the clamping head can circumferentially rotate by taking the screw rod as an axis; and a clamping nut matched with the screw rod is sleeved on the screw rod and on the inner side and the outer side of the mounting sleeve. Like this, the clamping head can form the centre gripping with the guardrail horizontal pole to support the guardrail horizontal pole, and establish it into circumferential direction's structure, can adjust the angle of its clamping part, with the inclination that adapts to the guardrail horizontal pole. After the two clamping nuts on the screw rod are matched with the screw rod, the screw rod can be fixed on the telescopic vertical pipe, and meanwhile, the screw rod can be adjusted front and back before fastening, so that the relative distance between the clamping head and the stair guardrail cross rod can be adjusted, and the clamping head and the guardrail cross rod are clamped mutually.

Furthermore, the clamping head comprises a stop block and at least one pair of clamping plates fixed on the outer side of the stop block, each pair of clamping plates are arranged at intervals, and a clamping opening matched with the cross bar of the stair guardrail is formed between the pair of clamping plates. Like this, the dog on the clamping head cooperates the back with the centre gripping mouth that splint formed, can effectively form the centre gripping to the guardrail horizontal pole, with guardrail horizontal pole card in the centre gripping mouth.
