Technical Field

The utility model relates to a building construction tool, specifically speaking relates to a stair receive face and use eyelidretractor.

Background

Building need build the template when pouring stair, then to pouring concrete in the template, the pouring is accomplished the back because the tread unevenness has sunkenly, consequently needs constructor to stand and trowels the tread with the cement on founding the mould, because the width of founding the mould is limited, constructor stands on and can stand unstably, often leads to trampling on the tread, leads to the tread to suffer to destroy and need fill the concrete again.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects of the prior art, the utility model aims to provide a supporter for stair closing surfaces, which overcomes the defects in the prior art.

In order to achieve the purpose, the utility model provides a supporter for stair receipts face, the supporter for stair receipts face be by at least three brace table grafting constitution, the brace table include two curb plates and a footboard, two the curb plates slope parallel arrangement and pass through the connecting rod fixed, the semicircle boards at both ends of footboard weld respectively fixed axle and double-screw bolt, the fixed axle pass the round hole of curb plate and with round hole clearance fit, the double-screw bolt pass the circular arc hole on the curb plate with nut threaded connection, one end of curb plate have the picture peg, the other end has the slot;

the pedal is composed of a horizontal plate shaped like a Chinese character 'ji', two vertical plates and two semicircular plates, wherein the two semicircular plates are positioned at two ends of the upper side of the horizontal plate shaped like a Chinese character 'ji', and the vertical plates are positioned at the bottom of the horizontal plate shaped like a Chinese character 'ji'.

As a further description of the supporter for stair closing surface of the present invention, preferably, the vertical plate is perpendicular to the bottom surface of the horizontal plate and parallel to the left and right side surfaces of the horizontal plate.

As a further description of the supporter for stair closing surface of the present invention, preferably, the number of the supporting platforms is 3-7.

The utility model has the advantages that:

1. the utility model discloses can come to peg graft a plurality of brace tables according to the ladder figure of pouring stair, put it on stair, every footboard all supports on founding the mould, and this eyelidretractor forms a stable ladder of trampling, and constructor can trample and receive the face on it, can not take place the unstable condition, can not shelter from stair tread when receiving the face simultaneously, can guarantee to receive the face effect.

2. The utility model discloses can dismantle when not using, conveniently carry and assemble.

3. The utility model discloses the inclination of every brace table's curb plate can change, can be applicable to different stair inclination's requirement, makes its receipts face that is applicable to different inclination stairs.

Detailed Description

In order to further understand the structure, characteristics and other objects of the present invention, the following detailed description is given with reference to the accompanying preferred embodiments, which are only used to illustrate the technical solution of the present invention and are not intended to limit the present invention.

The supporter for the stair closing surface is formed by splicing at least three supporting tables 1, each supporting table comprises two side plates 2 and a pedal 5, the two side plates are obliquely and parallelly arranged and are fixed through connecting rods 15, fixing shafts 10 and studs 11 are welded on semicircular plates 8 at two ends of each pedal respectively, the fixing shafts penetrate through circular holes of the side plates and are in clearance fit with the circular holes, the studs penetrate through circular hole 9 in the side plates and are in threaded connection with nuts, an inserting plate 4 is arranged at one end of each side plate, and an inserting groove 3 is arranged at the other end of each side plate;

the pedal is composed of a horizontal plate 6 shaped like a Chinese character 'ji', two vertical plates 7 and two semicircular plates, wherein the two semicircular plates are positioned at the two ends of the upper side of the horizontal plate shaped like a Chinese character 'ji', and the vertical plates are positioned at the bottom of the horizontal plate shaped like a Chinese character 'ji'.

In a second embodiment, the vertical plate is perpendicular to the bottom surface of the horizontal plate and parallel to the left and right side surfaces of the horizontal plate.

In a third embodiment, the number of the support platforms is 3 to 7, which further describes the supporter for a stair closing surface in the first embodiment.

The working principle is as follows: when in use, as shown in figure 9, a corresponding number of support tables are selected according to the number of treads of a stair 12, then the support tables are mutually inserted, the inserting plate of the side plate of the first support table is inserted into the inserting groove of the side surface of the second support table, thus the safety of the device is realized after the support tables are inserted, the whole device is placed on the stair, the pedal is pressed on a vertical mould 13 of the stair, thus, when the face folding operation of the stair is carried out, a constructor steps on the pedal by using a cement trowel to fold the face, meanwhile, the pedal is pressed on the vertical mould without shielding the treads and influencing the face folding of the stair, a stable stepping ladder is formed after the support tables are inserted, so that the constructor can stably step on the pedal, meanwhile, the device can be stably supported on the stair, the pedal is provided with a horizontal plate in a shape like Chinese character 'ji', a structure can lead out the position of a fixing plate 14 of the stair, the fixed plate is prevented from interfering the installation of the device;

when stair inclination changes, as shown in fig. 10, according to the inclination of stair fixed plate, the nearly font horizontal plate that keeps the footboard is in horizontal position, all loosen the nut on two curb plates of brace table, it makes the angle between curb plate and the horizontal plane the same with the inclination of fixed plate to rotate the curb plate, then screw up the nut, peg graft a plurality of brace tables after the angular adjustment of curb plate again, put it on stair after the completion of pegging graft, constructor's foot is stepped on and is received the face with the cement trowel on the footboard can, take off the device after finishing using, pull out one of brace table, realize the dismantlement of device.

It should be noted that the above mentioned embodiments and embodiments are intended to demonstrate the practical application of the technical solution provided by the present invention, and should not be interpreted as limiting the scope of the present invention. Various modifications, equivalent substitutions and improvements will occur to those skilled in the art and are intended to be within the spirit and scope of the present invention. The protection scope of the present invention is subject to the appended claims.
