Description
Technical field
The invention belongs to technical field of building construction, especially relates to a kind of positioning stool being less than or equal to 100mm Bars In Poured Concrete Slab negative bending moment rib for thickness.
Background technology
In building operations, for ensureing position and the reinforcement cover of Bars In Poured Concrete Slab negative bending moment rib, need to arrange split heads at negative bending moment rib place, traditional hogging moment ledges stool of pulling up a horse adopts the "Ji" type of reinforcement fabrication or elongated split heads, although these two kinds of steel bar horse-shaped benchs can play a role, often run into effect when thickness is less than 100mm Bars In Poured Concrete Slab undesirable, the height of "Ji" type split heads only has 30mm ~ 40mm, this split heads not easily makes, and supports negative bending moment reinforcing bar built on the sand; And elongated split heads cost of manufacture is high; This traditional two breeds of horses stool causes due to Bars In Poured Concrete Slab variable thickness simultaneously, causes specification many, is not easy to management.
Summary of the invention
The invention will solve above technical problem, a kind of positioning stool being less than or equal to 100mm Bars In Poured Concrete Slab negative bending moment rib for thickness is provided, this split heads supports negative bending moment reinforcing bar, form 3 one sides, support negative bending moment reinforcing bar very firm, there will not be split heads to tumble phenomenon, and structure is simple, design science is reasonable, safe and reliable, cost is lower, easy for installation, make easily.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: a kind of positioning stool for Bars In Poured Concrete Slab negative bending moment rib, comprise two transverse support bar, the head end of two described transverse support bar is fixedly connected with, be equipped with a vertical supporting bar immediately below each described transverse support bar, described vertical supporting bar is connected with described transverse support bar tail end.
Further, the head end angle of two described transverse support bar is 30 ° to 40 °.
Further, the head end arc transition of two described transverse support bar connects.
Further, described vertical supporting bar and described transverse support bar tail end angle are 45 °.
Further, described transverse support bar and described vertical supporting bar are screw-thread steel structure.
The advantage that the invention has and good effect are: a kind of positioning stool for Bars In Poured Concrete Slab negative bending moment rib, can solve and be less than or equal to 100mm Bars In Poured Concrete Slab negative bending moment steel bar horse-shaped bench stable problem, this split heads in use, form 3 one sides, support negative bending moment reinforcing bar effect firm, there will not be split heads to tumble phenomenon.In addition, the invention make simple, easy to use, save material, uniform specification, be convenient to management, and firm supporting.

Fig. 3 is the invention layout plan.
In figure: 1, transverse support bar; 2, vertical supporting bar; 3, distribution bar;
4, negative bending moment rib; 5, concrete.
Detailed description of the invention
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
As Figure 1-3, a kind of positioning stool for Bars In Poured Concrete Slab negative bending moment rib, comprise two transverse support bar 1, the head end of two described transverse support bar 1 is fixedly connected with, be equipped with a vertical supporting bar 2 immediately below each described transverse support bar 1, described vertical supporting bar 2 is connected with described transverse support bar 1 tail end.The head end angle of two described transverse support bar 1 is 30 ° to 40 °.The head end arc transition of two described transverse support bar 1 connects.Described vertical supporting bar 2 is 45 ° with described transverse support bar 1 tail end angle.
For a most preferred embodiment for the positioning stool of Bars In Poured Concrete Slab negative bending moment rib, this split heads adopts diameter 8 to 10mm screw-thread steel to make, and is placed between lower net plate muscle and upper negative bending moment rib 4 mesh sheet.First install Bars In Poured Concrete Slab lower net plate muscle during installation, then install mesh sheet muscle and comprise negative bending moment rib 4 and distribution bar 3, finally install split heads, split heads can not adopt ties up a colligation, directly presses shown in Fig. 2, Fig. 3 and places.
A kind of positioning stool for Bars In Poured Concrete Slab negative bending moment rib disclosed in the invention, main location thickness is less than or equal to 100mm Bars In Poured Concrete Slab negative bending moment rib 4, split heads adopts diameter 8 to 10mm screw-thread steel to make, the angle of split heads transverse support bar 1 controls at 30 ° to 40 °, split heads transverse support bar 1 hooked ends and vertical supporting bar 2 are 45 ° with the angle of transverse support bar 1, vertical supporting bar 2 length is 50mm, and transverse support bar 1 cut to lengthen is at 250 to 280mm.Split heads directly penetrates from negative bending moment rib 4 mesh sheet top when installing, and the direction of split heads is consistent with the direction of negative bending moment rib 4, and the height of split heads can be adjusted by the angle of split heads and reinforced mesh.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
