Can the elevator rail bracket be fixed on ordinary red bricks?

No. Rationale:

The elevator guide rail support is the main backing of the elevator running up and down, because there may be a slight shaking phenomenon during the operation of the elevator, so it is possible to cause the linkage of the guide rail support, which may cause the loosening of the elevator guide rail support. The compressive strength of ordinary red bricks is lower than that of concrete structures, so the bolts fixed to it through the guide rail bracket are easy to cause loosening, which may cause hidden dangers in terms of safety first, so it is not recommended to use them.

The correct method is that the guide rail bracket is fixed on the reinforced concrete base layer, and the strong gripping force of the reinforced concrete can play a better connecting role, and the conventional vibration will not have any effect.

Your elevator shaft is made of red bricks, the old building in the seventies and eighties, the guide rail bracket can not be directly and simply fixed on the red brick, you can refer to the Beijing local standard DB11 420-2007 construction, part of the reference drawings are as follows:

When installing the guide rail bracket on the ordinary red brick wall, first measure the position, remove the hole in the red brick wall, the size is 240 240 150mm as shown in Figure (F), and then use high-grade concrete cement to build the embedded steel parts, and then install the guide rail bracket after it solidifies to reach the use strength.

This is definitely not possible, not in front of the window and in the expansion screws!! Safe!!!

Inserts or wall screws can be used. Wall screws are relatively simple and convenient, and are more often used.

Then you need to wear wall bolts, and you can't simply use expansion wires.

Summary. Hello, dear, I am glad to answer for you How to fix the elevator rail bracket? A:

There is embedded iron on the wall of the elevator shaft: check the position of the embedded iron according to the vertical line of the installation rail support, and remove the concrete on the surface of the embedded iron. = 16mm, the length is generally not more than 300mm.

When the length exceeds 200mm, the end is fixed on the wall of the well with an expansion bolt of not less than 16, and the lap length of the steel plate and the embedded iron is not less than 50mm, and it is required to be fully welded on three sides. The hoistway wall of the elevator guide rail is a concrete cast-in-place structure and there is no embedded iron, and the expansion bolt is used to directly fix the guide rail support.

Hello, dear, I am glad to answer for you How to fix the elevator rail bracket? Answer: There is embedded iron in the elevator shaft wall

Check the position of the embedded iron according to the perpendicular line of the installation rail support, and remove the concrete on the surface of the embedded iron, if its position is offset, and does not meet the requirements of the installation position, the steel plate can be repaired and welded on the embedded iron. = 16mm, the length is generally not more than 300mm. When the length exceeds 200mm, the end is fixed on the wall of the well with an expansion bolt of not less than 16, and the lap length of the steel plate and the embedded iron is not less than 50mm.

The hoistway wall of the elevator guide rail is a concrete cast-in-place structure and there is no embedded limb iron, and the expansion bolt of the stool is used to directly fix the guide rail support.

What is forbidden on the work plane after the scaffolding is erected.

Pro, after the scaffolding is erected, the work plane prohibitions: 1. Before the scaffolding is erected, the foundation plane is inspected, and the level is leveled by pulling the wire to ensure that the scaffold is supported in the same horizontal plane, so as to ensure that the force of the scaffold is uniform, and the close placement of each connection point is ensured during construction, and it is strictly forbidden to connect falsely. 2. In order to prevent the concentrated load transmitted by the legs from cracking the cushion concrete, the square wood is cushioned on it, the thickness of the square wood is not less than 5cm, and the width is not less than the adjustable base under the base installation pole, and the length of the screw rod and the nut shall not be less than 5 buckles, and the length of the blind extension should not exceed 30cm, and the length inserted into the vertical rod shall not be less than 30cm.

The base of the pole should be closely attached to the square wood, square wood and the ground hardened by the rental liquid, and there should be no hollowing and loosening.
