Abstract
The utility model belongs to the technical field of the wall building material technique and specifically relates to a collection hoist and mount are positioned integrative prefabricated staircase, its stair includes go up ground connector, stair body, ladder and lower ground connector, be equipped with the reinforcement reinforcing bar in the last ground of connector, stair body, ladder and the lower ground connector, its characterized in that the outside of last ground connector and lower bottom surface connector on be equipped with U type recess respectively, the last ground connector of U type recess lower extreme with be equipped with the location boss on the connector of ground down, have that the location is accurate, compressive property is strong, safe firm, the high advantage of shock resistance ability.
Description
Technical field
The utility model relates to wall body building material technical field, and specifically a kind of accurate positioning, the collection lifting that compressive property is strong, safety and firmness, shockproof properties are high are positioned the precast stair of one.
Background technology
Prefabricated, be exactly the module that will use of engineering or plate, when making prefabricated component, first with planking nail hollow mould, in the hollow part distribution of model after reinforcing bar, hollow parts is filled with cement, Deng dry rear knock-off plank, remaining has been exactly prefabricated component, precast plate is a lot of in architectural use, the cement board that ditch as highway side covers, cement board roof being done isolation layer is all prefabricated component, along with the development of building trade, precast floor slab, precast wall body is obtained for and develops rapidly, in work progress, not only increase operating efficiency, also reduce the labour intensity of staff simultaneously, precast stair arises at the historic moment, it is fastening that the general inside of current precast stair is provided with reinforcing bar, then the precast stair of stairway form is made, these stair due to inner reinforcing bar linearly, flexural deformation is easy to after receiving pressure, particularly when receiving pressure, the stair body of notch cuttype will produce pulling force to upper ground surface connector and lower ground connector, and then make upper ground surface connector produce extremely strong pulling force to upper ground surface and lower ground connector to lower ground, will cause upper ground surface connector and lower ground connector respectively with upper ground surface and generation crack, lower ground, also potential safety hazard is there is the while of inaesthetic, cause the service life reduction of stair, particularly when mounted, due to the unbalance of stair, major part a dead lift, therefore the labour intensity of staff is increased, also reduce operating efficiency simultaneously.
Summary of the invention
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provides a kind of accurate positioning, precast stair that compressive property is strong, safety and firmness, shockproof properties are high collection lifting is positioned one.
A kind of collect lifting be positioned one precast stair, stair comprise upper ground surface connector, stair body, ladder and lower ground connector, reinforced steel is provided with in upper ground surface connector, stair body, ladder and lower ground connector, the outside that it is characterized in that described upper ground surface connector and bottom surface connector is respectively equipped with U-shaped groove, and upper ground surface connector and the lower ground connector of U-shaped groove lower end are provided with positioning boss.
U-shaped groove inner wall described in the utility model is provided with the U-shaped steel plate with fit depressions, and that reinforces U-shaped groove bears intensity.
The cross section of positioning boss described in the utility model is trapezoidal in what stand upside down, and location is quick, accurate, convenient.
The utility model is due to the outside of described upper ground surface connector and bottom surface connector being respectively equipped with U-shaped groove, upper ground surface connector and the lower ground connector of U-shaped groove lower end are provided with positioning boss, U-shaped groove ensure that lifting is convenient, simultaneously because its inside is provided with the U-shaped steel plate with fit depressions, that reinforces U-shaped groove bears intensity, improve safety factor, simultaneously the upper ground surface connector of U-shaped groove lower end and lower ground connector are provided with positioning boss, the location and installation of convenient lifting staff, guarantee that location fast, accurately, there is accurate positioning, compressive property is strong, safety and firmness, shockproof properties advantages of higher.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in drawings, a kind of collect lifting be positioned one precast stair, stair comprise upper ground surface connector 1, stair body 2, ladder 3 and lower ground connector 4, upper ground surface connector 1, stair body 2, reinforced steel 5 is provided with in ladder 3 and lower ground connector 4, the outside that it is characterized in that described upper ground surface connector 1 and bottom surface connector 4 is respectively equipped with U-shaped groove 6, upper ground surface connector 1 and the lower ground connector 4 of U-shaped groove 6 lower end are provided with positioning boss 8, described U-shaped groove 6 inwall is provided with the U-shaped steel plate 7 with fit depressions, that reinforces U-shaped groove 6 bears intensity, the cross section of described positioning boss 8 is trapezoidal in what stand upside down, location fast, accurately, convenient.
The utility model in use, first be stuck in the U-shaped groove 6 at precast stair two ends by lifting device, realize lifting, precast stair is positioned on upper ground surface and lower ground by the positioning boss 8 after lifting on upper ground surface connector 1 and lower ground connector 4, the utility model is due to the outside of described upper ground surface connector 1 and bottom surface connector 4 being respectively equipped with U-shaped groove 6, upper ground surface connector 1 and the lower ground connector 4 of U-shaped groove 6 lower end are provided with positioning boss 8, U-shaped groove 6 ensure that lifting is convenient, simultaneously because its inside is provided with the U-shaped steel plate 7 matched with groove 6, that reinforces U-shaped groove 6 bears intensity, improve safety factor, simultaneously the upper ground surface connector 1 of U-shaped groove 6 lower end and lower ground connector 4 are provided with positioning boss 8, the location and installation of convenient lifting staff, guarantee that location fast, accurately, there is accurate positioning, compressive property is strong, safety and firmness, shockproof properties advantages of higher.
