Detailed Description

The present application is described in further detail below with reference to figures 1-5.

The embodiment of the application discloses install cement column braced frame for elevator additional to the example is explained this application to two water conservation mud columns concatenations.

Referring to fig. 1, install cement column braced frame for elevator additional and include vertical setting at the stand in 1 four corners of elevartor shaft, every stand forms by the concatenation of many prefabricated cement columns 2 head and the tail, and a water conservation mud column 2 of lower extreme is fixed in advance to be buried underground in elevartor shaft 1. The joint of the two water-saving mud columns 2 is provided with a connecting piece 3, and the upper and lower water-saving mud columns 2 are connected and fixed through the connecting piece 3. Four stands enclose and establish square braced frame, equal level fixedly connected with crossbeam 4 between two stands of each side, and the hookup location of crossbeam 4 and stand is located two concatenation nodes with cement post 2. Guide rails 5 are vertically arranged on two opposite sides in the supporting frame, and the guide rails 5 are fixed on the cross beams 4 on the corresponding sides through bolts. A construction platform 6 is vertically and slidably connected to the guide rail 5, and materials can be hoisted and transported through the construction platform 6.

Referring to fig. 2 and 3, the connecting member 3 includes a clamping ring 31 and a plurality of positioning plates 32, the clamping ring 31 is clamped on the outer wall of the cement column 2 along the circumferential direction, and the positioning plates 32 are welded on the clamping ring 31 along the axial direction of the cement column 2 and extend on the clamping ring 31 along two directions. The snap ring 31 includes two cardboard 311 that are the arcuation, and the one end of two arc cardboard 311 is through a round pin hub connection, and two cardboard 311 can take place relative rotation round the round pin axle and then make two cardboard 311 open or closed, and the other end integrated into one piece of two cardboard 311 has an extension board 312, and two extension boards 312 are close to then fixed through bolted connection when two cardboard 311 rotate to the closure, and then will link a cardboard 311 locking on cement column 2.

A plurality of locating plates 32 are along circumference evenly spaced distribution on snap ring 31 to four locating plates 32 are the example, and all welded on each cardboard 311 has two locating plates 32, and when cardboard 311 joint was on cement column 2, four locating plates 32 evenly distributed were in the circumference of cement column 2 and support tightly and fix cement column 2 chucking at cement column 2 outer wall. In order to improve the fixing effect of the connecting piece 3 on the two water-saving mud columns 2, reinforcing plates 33 are welded at two ends of the positioning plate 32 on each side, and the reinforcing plates 33 abut against the outer wall of the cement column 2 to further improve the fixing capacity of the cement column 2.

In order to improve the splicing stability of the two water-saving mud columns 2 and enhance the fixing capacity of the connecting piece 3 on the cement columns 2 and improve the aesthetic degree, referring to fig. 2 and 4, a columnar boss 21 is arranged at one end of each cement column 2, an inner groove 22 corresponding to the boss 21 is formed at the other end of each cement column 2, and the boss 21 and the inner groove 22 are integrally formed when the cement columns 2 are prefabricated. When the two water-saving mud columns 2 are spliced, the convex part 21 of one water-saving mud column 2 is inserted into the inner groove 22 of the other water-saving mud column 2, so that the two water-saving mud columns 2 are positioned and primarily fixed when being spliced. In addition, the length of the protruding part 21 is slightly greater than the depth of the inner groove 22, on the basis, when the protruding part 21 is inserted into the inner groove 22, a certain gap exists between the two water-saving mud columns 2, the width of the gap is consistent with the width of the clamping plate 311 along the axial direction, the clamping plate 311 is clamped in the gap of the two water-saving mud columns 2 when the connecting piece 3 is installed, and therefore the possibility that the connecting piece slides along the axial direction is eliminated.

Further, offer constant head tank 23 on the outer wall of cement column 2, the position and the size of constant head tank 23 and locating plate 32 and gusset plate 33 one-to-one, can just in time imbed locating plate 32 and gusset plate 33 in constant head tank 23 when installation connecting piece 3, through this setting, can eliminate connecting piece 3 along circumferential direction's possibility. In order to further enhance the appearance, the positioning grooves 23 are formed to a depth corresponding to the thickness of the corresponding positioning plate 32 and the corresponding reinforcing plate 33. After the connecting piece 3 is installed, the outer sides of the snap ring 31 and the positioning plate 32 are flush with the outer wall of the cement column 2.

The cross beam 4 is connected between the two upright posts on the same side, and can further fix the upright posts. Referring to fig. 2 and 3, in order to facilitate connection of the cross member 4, the extension plates 312 are U-shaped, and U-shaped openings of the extension plates 312 on both sides are disposed opposite to each other. A square mounting frame 34 is welded on the snap ring 31, and the mounting frame 34 and the extending plate 312 near the side form an included angle of 90 degrees. When the cross beam 4 is installed, one of the two cross beams 4 connected with the same stand column is inserted into a frame surrounded by the two U-shaped extension plates 312 and fixed by a bolt, one end of the other cross beam 4 is inserted into the installation frame 34 and fixed by a bolt, and the other end of the cross beam 4 is fixed in the same manner. Four cross beams 4 on the same layer can play a role in further reinforcing the cement column 2 after being fixed.

Referring to fig. 5, in order to facilitate the construction platform 6 to slide up and down along the guide rail 5, a guide block 62 is welded on the construction platform 6, and the guide block 62 is slidably connected with the guide rail 5 to improve the sliding stability of the construction platform 6. The bottom of the construction platform 6 is provided with a winch 61, the winch 61 is provided with two groups of wire reels 611 which are respectively positioned at two sides of the construction platform 6 close to the guide rail 5, the wire reels 611 are wound with a steel wire rope 612, referring to fig. 1 again, the head end of the steel wire rope 612 is connected to the top of the guide rail 5, and the winch 61 drives the steel wire rope 612 to be wound and unwound so as to drive the construction platform 6 to lift.

In the embodiment, two water-saving mud columns 2 are taken as an example for explanation, in other embodiments, the number of the spliced cement columns 2 can be adjusted according to specific requirements, and the embodiment of the present application is not limited.

The implementation principle of installing cement column braced frame for elevator additional in this application embodiment is: when carrying out the elevator and installing the construction additional, at first bury a water conservation mud post 2 underground respectively in the four corners position of elevartor shaft 1, four water conservation mud posts 2 enclose out an overall framework structure, then splice the installation and use connecting piece 3 to fix two water conservation mud posts 2 from top to bottom at the top of each water conservation mud post 2, install crossbeam 4 in step when splicing cement post 2. After the cement columns 2 are spliced and the cross beams 4 are installed, the guide rails 5 and the construction platform 6 are installed, and materials can be hoisted and transported for the splicing installation of the subsequent cement columns 2 by utilizing the construction platform 6. The utility model provides a pair of install cement post braced frame for elevator additional uses the stand that has the 2 concatenations of cement post to form and replaces the steel construction frame that prior art is commonly used, can provide the rigidity demand the same with steel construction frame, simultaneously, and the simple installation, the efficiency of construction is high to do not receive the restriction of construction site scope.
