Description

The load girder steel element of encorbelmenting of scaffold
Technical field
The utility model relates to technical field of buildings, the specific load girder steel element of encorbelmenting that relates to scaffold.
Background technology
The load girder steel of encorbelmenting of existing carrying scaffold generally adopts depth of section to be not less than the 16# i iron of 160mm, and its tail end is anchored on the flooring, the length of anchoring is 1.25 times of cantilever span, because this kind Cantilever Beams carrying energy is not strong, so each cantilever steel girder will configure a vertical rod, therefore there is the following defective of defective in spacing 1.5m: the carrier steel using amount of the scaffold of 1) building with the above-mentioned this load steel of encorbelmenting is large; 2) the single long weight of the load girder steel length of encorbelmenting is large, and installing/dismounting will cooperate with tower crane, wastes time and energy, and takies the tower crane time long; 3) anchoring of girder steel tail end is not tight, lateral rigidity, poor stability; 4) cantilever steel girder all will be arranged in every vertical rod position, copies so that form the following heavy frame rod member layout of scaffold, and is crisscross especially at rotation angle position especially; 5) girder steel is arranged on the flooring, is unfavorable for the flooring construction; 6) in the box out of shear wall position, to be inconvenient to repair, seepage also easily appears.
Summary of the invention
The purpose of this utility model is to solve the deficiency of above-mentioned prior art, proposes a kind of load girder steel element of encorbelmenting of scaffold, and its technical scheme is as follows:
The described load girder steel element of encorbelmenting, place on the construction wall, comprise the load girder steel of encorbelmenting, also comprise junction plate and load bolt, nut, described junction plate is connected to an end of the described load girder steel of encorbelmenting, load bolt one end passes described junction plate and the body of wall corresponding nut that spins, and fixedly encorbelments the load girder steel on described wall outer side face.
The described load girder steel element of encorbelmenting further designs and is, the described load girder steel of encorbelmenting is made of two channel-section steels, and two channel-section steels form the girder steel of I-shaped cross-section with the relatively symmetrical placement of bottom land wall.
Described encorbelment the load girder steel element further design be, described junction plate is provided with at least two installing holes, described load bolt passes this installing hole and the described body of wall corresponding nut that spins.
The described load girder steel element of encorbelmenting further designs and is, being vertical or being 45° angle of the described load girder steel of encorbelmenting is connected with junction plate.
Heavy frame beneficial effect of the present utility model is: 1) require to take full advantage of the channel-section steel of throwing aside under the constant prerequisite in guaranteed strength, make twice laid, economize on resources; 2) encorbelment that the length of load girder steel shortens, quality alleviates, make things convenient for installing/dismounting, do not need tower crane to cooperate, increase work efficiency; Encorbelment the load girder steel mounting means again the reinforcing pull rod carrying energy of engages adjustable greatly improve, the spacing of the load girder steel of encorbelmenting increases to 3 meters, saves 3/4 left right model steel using amount; 3) cantilever steel girder is arranged in metope, does not affect the flooring construction; 4) shear wall does not need box out, leakproof hidden danger; 6) can realize standardized designs, but both quality requirements of guaranteed strength improves safety, can improve again highly versatile and reusable, saves construction cost.

The specific embodiment
Contrast Fig. 1, the utility model load girder steel element of encorbelmenting mainly is comprised of the load girder steel 1 of encorbelmenting, junction plate 8, load bolt 6.Referring to Fig. 2, the placing so that bottom land wall relative mode is symmetrical of two channel-section steels, and be vertically welded on the junction plate 8, form the load girder steel element of vertically encorbelmenting of I-shaped cross-section.Junction plate 8 is provided with two installing hole 8a(also can arrange more installing hole certainly as required), load bolt 6 passes this installing hole 8a on the junction plate and body of wall 20 and the pad 6b corresponding nut 6a that spins, and the load girder steel 1 of encorbelmenting is connected on the lateral surface of body of wall 20.
Above-mentioned encorbelment load girder steel element and vertically load girder steel, two reinforcing pull rods 4 and flower basket bolt 3 consist of the pull-up heavy frame of encorbelmenting, and see also Fig. 3.The load girder steel 1 of encorbelmenting of some parallel placements is set at main wall body 20 lateral surface sustained heights, the load girder steel element of vertically encorbelmenting evenly is arranged on respectively on the lateral surface of mutually vertical body of wall, referring to Fig. 4, the adjacent two load girder steel element spacings of vertically encorbelmenting are not more than 3 meters.Two mutual vertical wall bodies cross the end corner be provided with a tilting load girder steel element of encorbelmenting, load girder steel 1 ' one end of encorbelmenting in this member is 45° angle with junction plate and is connected.It welds vertical load girder steel on the external side of two vertical wall corresponding to an end of the above-mentioned end corner that crosses and load girder steel 1 corresponding position of encorbelmenting on the tilting load girder steel element of encorbelmenting.Vertically load girder steel 5 is i iron, shelves and is connected in and encorbelment on the load girder steel 1.
Each load girder steel 1 of encorbelmenting is drawn by reinforcing pull rod 4 and hangs, and two reinforcing pull rods 4 connect by flower basket bolt 3.Flower basket bolt 3 is comprised of nut 3a, the 3b of two round steel 3c and different rotation directions, referring to Fig. 5.One end of two reinforcing pull rods 4 is screwed in respectively in the nut of two different rotation directions, and the other end of two reinforcing pull rods 4 is connected with an end that is fixed on body of wall top engaging lug seat 7 and the load girder steel 1 of being connected respectively.Just can tighten up or loosen reinforcing pull rod 4 by different directions rotation flower basket bolt 3, regulate reinforcing pull rod 4 tensile forces with this, make adjusting very convenient.
When the load girder steel element of encorbelmenting of the present utility model uses, share fractional load by reinforcing pull rod 4, and tighten up or loosen reinforcing pull rod 4 by rotation flower basket bolt 3, regulate reinforcing pull rod 4 tensile forces with this, that the load girder steel of encorbelmenting is stressed more reasonable, thereby the carrying energy of the load girder steel of encorbelmenting is improved greatly, the spacing of load girder steel of encorbelmenting increases, the length of load girder steel self of encorbelmenting also shortens greatly, so use with the heavy frame that the load girder steel element of encorbelmenting of the present utility model is built, the steel amount only has 1/4 of existing heavy frame steel using amount, and the Saving steel amount is unexpectedly up to 3/4.When constructing simultaneously, cantilever steel girder need not be anchored at flooring, thereby do not need in the shear wall box out, the sorrow of leakproof hidden danger does not affect the flooring construction.The cantilever steel girder construction weight is light simultaneously, makes things convenient for installing/dismounting, does not need tower crane to cooperate, and is easy for installation, increases work efficiency.The cantilever steel girder member can be realized standardized designs in addition, can ensure the quality of products, and improves safety, also increases highly versatile and reusable, saves construction cost.
