As shown in Fig. 1 to 15, a kind of steel concrete wall beam strengthen device, by steel pipe top beam 11, force transmission element 12, helix swiveling plate 13 and screw thread pole 14 form, described screw thread pole 14 is made up of lower substrate and the threaded rod being vertically connected on thereon, helix swiveling plate 13 installed by the threaded rod of described screw thread pole 14, described helix swiveling plate 13 is welded to form by the female hollow cylinder of band and round steel handle, on threaded rod above described helix swiveling plate 13, cover has force transmission element 12, multidiameter is formed outside described force transmission element 12, the comparatively large and helix swiveling plate 13 of lower diameter matches, the steel tube inner hole of upper diameter and steel pipe top beam 11 matches, on described force transmission element 12, cover has steel pipe top beam 11, described steel pipe top beam 11 is made up of steel pipe connected vertically below upper end top board and top board, described pipe diameter is greater than the external diameter of threaded rod.
The lower substrate of described screw thread pole 14 is connected with welding manner with the screw thread being vertically connected on thereon.
The upper end top board of described back timber part 11 is connected with welding manner with steel pipe connected vertically below top board.
A wall beam Enhancement Method for steel concrete wall beam strengthen device, step is as follows:
A, under beam on brick wall 1, some digging hole in walls 3 are set below wall beam 2;
B, strengthen device to be loaded in digging hole in wall 3;
C, screw thread pole 14 is arranged on digging hole in wall 3 position under beam, rotates helix swiveling plate 13 and by force transmission element 12, steel pipe top beam 11 is shored bottom wall beam 2, be supported between wall beam 2 and brick wall 1;
D, brick wall 1 part between digging hole in wall 3 got through, brick wall 1 and wall beam 2 support with strengthen device completely;
E, wall beam 2 is cleaned out below after, below wall beam 2, use the stupefied bar 6 of steel pipe support 5, the lumps of wood, wooden form 7 and supporting steel pipe 8 that concrete grouting mould is set, reserved concrete pouring gate 9;
F, placing of concrete;
After wall beam reinforced concrete 10 set strength of g, pouring reaches requirement, remove steel pipe support 5, the stupefied bar 6 of the lumps of wood, wooden form 7 and supporting steel pipe 8, removing the cross section, concrete pouring gate 9 position left over is leg-of-mutton plain concrete;
H, rotation helix swiveling plate 13 loosen the pressure to lower wall body, and then limit is removed body of wall limit and extracted screw thread pole 14 and helix swiveling plate 13 out, then removes force transmission element 12, finally adopt pea gravel concreten to close left hole.
In described step f, during placing of concrete, the face of building at concrete pouring gate 9 position is higher than original wall beam 2 bottom surface 2cm.
In Fig. 2, wall beam supports transfer process: before construction, the position of digging hole in wall 3 and quantity under beam, and the position of wall beam bracing or strutting arrangement and quantity, will determine, guarantee safety of structure through Specialized Theory checking computations.After digging hole in wall, substitute the part supporting role of brick wall 1 under beam with wall beam bracing or strutting arrangement 4.
In Fig. 3, wall beam supports situation: treat wall beam bracing or strutting arrangement 4 all installations, removes the brick wall masonry supporting wall beam 2 bottom and leave over, and bracing or strutting arrangement 4 substitutes whole supporting roles of brick wall 1 under beam, for the enhancing of wall beam 2 and reinforcing provide condition.
Wall beam formwork in Fig. 4: before the template system reinforced for wall beam is installed, wall beam 2 bottom concrete bottom will be cleaned out, and reaches the requirement about constuction joint of relevant specification and standard.When template system is installed, the stupefied bar 6 of steel pipe support 5, the lumps of wood, wooden form 7, supporting steel pipe 8, concrete pouring gate 9 constitute the template system of reinforcing steel bar concrete beam 10, and reinforcing steel bar concrete beam 10 tie with reinforcing bar and installation are carried out with model sheetinstallat synchronous matching.Treat that above work completes, get final product concreting, complete the making of reinforcing steel bar concrete beam 10.During concreting, in order to ensure the concrete density of reinforcing steel bar concrete beam 10, when concreting is to last, the face of building at concrete pouring gate 9 position is higher than original wall beam 2 bottom surface 2cm, and sprue gate Formation cross-section is leg-of-mutton plain concrete.
Wall beam support zone formwork situation in Fig. 1: wall beam bracing or strutting arrangement 4 and model sheetinstallat match, plays the supporting role of wall beam bracing or strutting arrangement 4 all the time, guarantees that work progress is implemented smoothly.
After Fig. 5 form removal, wall beam supports schematic diagram: after form removable, be that leg-of-mutton plain concrete 15 excises by the cross section, concrete pouring gate 9 position left over.After template system is removed, wall beam bracing or strutting arrangement 4 is still supported on brick wall, after reinforcing steel bar concrete beam 10 concrete strength reaches requirement, i.e. and dismountable wall beam bracing or strutting arrangement 4.
Fig. 6 reinforcing steel bar concrete beam schematic diagram: after wall beam bracing or strutting arrangement 4 is all removed, reinforcing steel bar concrete beam 10 assume responsibility for top whole load, and lower wall body is all removed, and completes steel concrete wall beam strengthen.
Each component part of wall beam bracing or strutting arrangement in Fig. 8 to Figure 15: wall beam bracing or strutting arrangement 4 is made up of steel pipe top beam 11, force transmission element 12, helix swiveling plate 13, screw thread pole 14 respectively.Wherein, steel pipe top beam 11, is made up of steel plate and steel-pipe welding; Force transmission element 12 is circular cross-section steel part; Helix swiveling plate 13 is welded to form by the female hollow cylinder of band and round steel handle; Screw thread pole 14 is formed by screwed round steel and Plate Welding.
Wall beam bracing or strutting arrangement assembling schematic diagram in Fig. 7: end face screw thread pole 14 being arranged on the brick wall 1 of digging hole in wall under beam, the movement produced when utilizing helix swiveling plate 13 to rotate, by force transmission element 12, steel pipe top beam 11 is shored bottom wall beam 2, reach and the load of wall beam 2 is substituted by wall beam bracing or strutting arrangement 4 object that body of wall is delivered to lower wall body.When wall beam bracing or strutting arrangement is removed, first rotation helix swiveling plate 13 loosens the pressure to lower wall body, and then limit is removed body of wall limit and extracted screw thread pole 14 and helix swiveling plate 13 out, then removes force transmission element 12, finally adopts pea gravel concreten to close left hole.
