Can the elevator guide stand be fixed on ordinary red bricks?
Your elevator shaft is red brick, seven and 80s old floor bar, guide brackets can not be directly fixed on the red brick, you can refer to Beijing local standard DB11/420-2007 construction, some of the reference map follows:In the installation guide rail bracket common brick wall, the first measurement of the location, the red brick tick hole, size 240 x 240 x 150MM figure (f), and high grade concrete cement pre buried steel piece solidating, solidified to use strength then you can install the guide bracket.Table B.6 inspection records for track support mounting DB11/420-2007Elevator numberHidden itemsGuide rail, bracket and bolt are buriedExamination siteGuide bracketConstruction dateSpecific dateContents and schematic diagram of the hidden units: mmSidewall structureApplicable processAdaptive chart numberA, B, C, D, e, fBuried iron thicknessNo less than 16.Bolt specification* MSpecification for type steelDovetail angleGamma less than 60 degreesEmbedment depthNo less than 120Wall hole sizeSlag cleaningConcrete mixture ratioCement: Sand: bean stonecuringdaycheckcheckmeaningseeAgree - hiddenAfter the re inspection will change.Specific dateReview opinionSpecific dateInspectorsConstruction unitCivil engineering unitInspectorInstallation project leaderConstruction inspector
Then you need wall bolts. You can't simply use expansion wires
Can not. Reason：Elevator guide rail bracket is elevator main backer, because there may be a slight shaking in the elevator is running, so it may cause the linkage of guide rail bracket, which may cause the elevator guide rail bracket loose. Compared with the concrete structure, the compressive strength of common red brick is lower than that of the concrete structure, so the bolt fixed on the guide rail is easy to be loosened, so that the safety hazard may be caused first, so it is not recommended to use.The correct method is that the guide rail is fixed on the reinforced concrete base, and the stronger gripping force of the reinforced concrete can bear the better connection effect, and the conventional vibration can not have any influence.
