Abstract
The utility model discloses a preformed hole device for a boiler membrane wall and belongs to the field of boiler processing. The preformed hole device for the boiler membrane wall comprises the membrane wall formed by welding a plurality of vertical steel pipes and flat steel. A rectangular through hole is formed in the position, where a preformed hole needs to be formed, on the membrane wall, the preformed hole device is arranged in the rectangular through hole, the preformed hole device comprises a rectangular frame, the rectangular frame is composed of a pair of parallel hollow transverse rods and a pair of parallel hollow longitudinal rods welded between the hollow transverse rods, and a rectangular steel plate is arranged in the rectangular frame. According to the preformed hole device, preformed holes can be reasonably formed in the longitudinal direction and the transverse direction of the membrane wall, the vertical steel pipes on the membrane wall do not need to be bent, manufacturing is easy, welding workloads are greatly reduced, installation is quite convenient, and the whole appearance molding of the membrane wall is concise and lively.
Description
Technical field
The utility model belongs to boiler manufacture field, is specially a kind of boiler diaphragm type wall preformed hole device.
Background technology
Boiler is because need to reserve the pilot holes such as manhole door, access door, burner, industrial television camera, fuel interpolation mouth, so the steel pipe on past membrane wall need to allow pipe, what is called allows the pipe be exactly the steel pipe of all these reserved area, bend to the left and right, make this region vacate the region of suitable size, facilitate the installation of manhole, burner etc.
Bending in process of steel pipe is comparatively complicated, often need to bend 10-20 root steel pipe, sometimes it is excessive that the same area in height has the equipment of a lot of preformed holes or required installation, not only need that the steel pipe that bends is more, radian is larger, and every steel pipe will bend a lot of Curved Continuous, time-consuming, seriously increase the difficulty of boiler component design and cost of manufacture and the man-hour of membrane wall; Moreover, in boiler erection, when maintenance, this structure is also suitable loaded down with trivial details, has equally greatly increased workload and the difficulty of installing.
Utility model content
The purpose of this utility model is to provide a kind of boiler diaphragm type wall preformed hole device, can effectively reduce the cost of manufacture of preformed hole, reduces installation workload, improves production efficiency and qualification rate.
The technical scheme that realizes above-mentioned purpose is: boiler diaphragm type wall preformed hole device, comprise by many vertical steel pipes and band steel and weld the membrane wall forming, it is characterized in that: on described membrane wall, the position of preformed hole to be arranged is provided with rectangular through-hole, in rectangular through-hole, be provided with preformed hole device, described preformed hole device comprises the rectangular frame that the hollow cross bar that arranged by pair of parallel and a pair of hollow vertical pole be arrangeding in parallel being welded between hollow cross bar form, the two ends of two hollow cross bars are all sealed, between two hollow vertical poles and two hollow cross bars, be connected, in described rectangular frame, be provided with rectangular steel plates, the surrounding sidewall of rectangular steel plates and rectangular frame welding, rectangular steel plates is used for offering preformed hole, the lower end of the vertical steel pipe that the rectangular through-hole top on described membrane wall is truncated is all tightly connected with the hollow cross bar that is positioned at top, the lower end of the vertical steel pipe that the membrane wall of rectangular through-hole top is truncated is all tightly connected with the hollow cross bar that is positioned at top, the upper end of the vertical steel pipe that the membrane wall of rectangular through-hole below is truncated is all tightly connected with the hollow cross bar that is positioned at below, and the vertical steel pipe that the rectangular through-hole above and below on membrane wall is truncated is connected with corresponding hollow cross bar respectively.
The utility model can carry out reasonable Arrangement preformed hole on the vertical and horizontal of membrane wall, vertical steel pipe on membrane wall is without bending, and making is simple, and welding job amount greatly reduces, install very conveniently, the moulding of membrane wall overall appearance is succinct, lucid and lively.

Fig. 1 is structural representation of the present utility model;
Fig. 2 be in Fig. 1 A-A to cutaway view;
Fig. 3 be in Fig. 1 B-B to cutaway view.
Detailed description of the invention
As shown in Figure 1, 2, 3, the utility model comprises by many vertical steel pipes 1 and band steel 2 and welds the membrane wall 3 forming, and on membrane wall 3, the position of preformed hole to be arranged is provided with rectangular through-hole 4, is provided with preformed hole device 5 in rectangular through-hole 4.
Preformed hole device 5 comprises the rectangular frame 8 that the hollow cross bar 6 that arranged by pair of parallel and a pair of hollow vertical pole 7 be arrangeding in parallel being welded between hollow cross bar 6 form, two hollow cross bars 6 adopt high-pressure seamless square tube, and the two ends of two hollow cross bars 6 are all sealed, two hollow vertical poles 7 adopt hollow circular-tube, and and two hollow cross bars 6 between be connected; In rectangular frame 8, be provided with rectangular steel plates 9, surrounding sidewall and the rectangular frame 8 of rectangular steel plates 9 weld, and rectangular steel plates 9 is for offering preformed hole.
The lower end of the vertical steel pipe 1 that the membrane wall 3 of rectangular through-hole 4 tops is truncated all be positioned at top hollow cross bar 6 seal weldings, the upper end of the vertical steel pipe 1 that the membrane wall 3 of rectangular through-hole 4 belows is truncated all be positioned at below hollow cross bar 6 seal weldings, the vertical steel pipe 1 that rectangular through-hole 4 above and belows on membrane wall 3 are truncated is connected with corresponding hollow cross bar 6 respectively.
