Abstract

The utility model discloses a buried-type steel purlin, which comprises a plurality of H-type profiled bars, rectangle steel plates and steel plates. Wherein, two H-type profiled bars are jointed and fixed by a plurality of rectangle steel plates; a plurality of ports are positioned at the middle plate of the H-type profiled bars in the longitudinal direction with the same distance between; the middle plate and the limb plate of the H-type profiled bars are connected by one plate at the middle of the next two ports in the longitudinal direction. The utility model is applicable to the construction of the foundation pit to make the reinforcing steel bar of the wall go through the steel purlin, which will not influence the structure concrete placement to ensure the development and continuity of the construction.

Description

But the flush type steel encloses the purlin device

Technical field

The utility model relates to the steel of using in a kind of base pit engineering steel support construction and encloses the purlin device.

Background technology

At present, support in the construction at the base pit engineering steel, structure is returned employed structure wall steel of the stage of building and is enclosed the generally making at the construction field (site) of purlin device, structure reinforcing bars can't run through steel and enclose purlin, and needs to disconnect, and makes that the globality of structure reinforcing bars skeleton is poor, steel encloses the purlin distortion greatly, influence structural concrete and build, structure construction can not be carried out and continuous operation smoothly, directly have influence on construction speed and construction quality.

Summary of the invention

The technical problems to be solved in the utility model provides in a kind of Foundation Pit Construction process, structure is returned and is made the structure wall reinforcing bar can run through steel when building the stage to enclose purlin, do not influence structural concrete and build, but make structure construction can carry out smoothly enclosing the purlin device with the flush type steel of continuous operation.

For the technical scheme that solves the problems of the technologies described above employing is: but a kind of flush type steel encloses the purlin device, comprises H shaped steel, rectangular steel plates, steel plate, two H shaped steel are arranged welding with several piece rectangular steel plates spacing, and splicing is fixing up and down; H shaped steel web position in H shaped steel is along its length by each perforate up and down of essentially identical spacing; The centre of every H shaped steel adjacent apertures with steel plate along its length up and down each one with H shaped steel in web and wing plate welding fix.

Perforate is a rectangular opening, and it is of a size of 150mm * 150mm, perforate spacing 300mm; The spacing that adds steel plate between the adjacent apertures is 300mm; The rectangular steel plates spacing is 800mm, and along rectangular steel plates fillet welding all around, its weld seam height is 10mm.

But flush type steel of the present utility model encloses the purlin device, has following beneficial effect:

1. but flush type steel of the present utility model encloses the perforate of purlin device can be made structure reinforcing bars can run through steel and enclose purlin and do not disconnect the globality of assurance structure reinforcing bars skeleton by the structure reinforcing bars pitch arrangement;

Water and smash the hole but but flush type steel 2. of the present utility model encloses purlin device perforate double as structural concrete, do not influence structural concrete and water and smash, thereby guarantee that steel encloses the concrete density of purlin substructure;

3. but flush type steel of the present utility model encloses the purlin device can be processed in advance in factory, only carries out the assembling or the welding procedure of this device length direction at the construction field (site), saves the engineering time greatly;

4. but flush type steel of the present utility model adopts steel plate as putting more energy into steel plate after enclosing the perforate of purlin device H type web, and it is little that steel encloses the purlin distortion, reaches the design rigidity requirement easily.

5. it is simple that but flush type steel of the present utility model encloses the purlin apparatus structure, and material is common, and it is big to enclose purlin rigidity, can satisfy most of base pit engineering steel and support construction.

Description of drawings

But Fig. 1 is the utility model flush type steel encloses purlin device floor map;

But Fig. 2 is the utility model flush type steel encloses purlin device cut-away view.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing and example.

As Fig. 1, shown in 2, structure reinforcing bars spacing, position rectangle opening 3 on its web 1.1 is pressed at web 1.1 positions in the H shaped steel 1 along its length, and bore size is 150mm * 150mm, perforate spacing 300mm, two H shaped steel 1 perforate center correspondences up and down; Add in the middle of the adjacent apertures 3 block plate 4 (360mm * 180mm * 12mm), spacing is 300mm, three limits of steel plate 4 respectively with the web 1.1 of H shaped steel 1 and wing plate 1.2 be welded to connect fixing, up and down each one along its length of weld seam 5 height 8mm, every H shaped steel 1.

Steel encloses purlin by H shaped steel 1 (400mm * 408mm * 21mm * 21mm) splicing up and down, should adjust before fixedly connected and make H shaped steel perforate center corresponding up and down, be connected and fixed and adopt rectangular steel plates 2 (two-sided being welded to connect of 300mm * 150mm * 16mm), steel plate 2 spacings are 800mm, along rectangular steel plates 2 fillet welding all around, double welded joint 6 high 10mm.
