Description
Technical Field
The utility model relates to a concrete box girder overhauls people's hole field, concretely relates to concrete box girder overhauls people's hole and uses template.
Background
In order to know the service state of the concrete bridge in time and repair possible problems, a circular overhaul manhole is reserved at the bottom of the beam to provide a passage between the outside and the inside of the box beam. Before the bottom plate of the box girder is poured, a man-hole template meeting design requirements needs to be erected, a cylindrical template formed by enclosing an upper panel and a lower panel and peripheral short wood boards is usually adopted, and in order to prevent the side surfaces of the box girder from obviously deforming under the action of lateral pressure of concrete during the pouring of the concrete, relatively thick panels are often selected. In order to prevent slurry from entering the interior of the formwork during concrete pouring and causing difficulty in formwork removal, good sealing between the upper and lower panels and the peripheral planks and between the peripheral planks needs to be achieved. When the concrete reaches the age of being able to disassemble the formwork, the top surface panel and the peripheral short wood boards are sequentially disassembled, the disassembling process is time-consuming and labor-consuming, the formwork can be used only once, and a large amount of wood is wasted. There is a need for a form and support method that has sufficient support force, adjustable cross-sectional dimension, easy assembly and disassembly, and can be reused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a concrete box girder overhauls people's hole and uses template solves present concrete and overhauls people's hole template and demolishs consuming time power, unable reuse and lead to the technical problem of wasting of resources.
The utility model adopts the following technical proposal:
a formwork for a concrete box girder overhaul manhole comprises a barrel body, a support frame and an adjusting bolt, wherein the barrel body comprises two sections which are overlapped, L-shaped fixing frames are arranged on the inner side walls of the two sections, through holes are formed in the fixing frames, the two fixing frames are arranged oppositely, the adjusting bolt penetrates through the through holes to connect the two fixing frames together, one end of the adjusting bolt is in threaded connection with a nut, and the nut is screwed to enable the two fixing frames to be drawn close to or drawn far away, so that the two sections are tightened or unfolded;
the support frame sets up in the inside of barrel, and the support frame includes the intermediate part, is radial a plurality of supports that are connected with on the intermediate part, and the front end of support leans on with the inner wall of barrel, provides the support for the barrel.
Preferably, the mount includes the diaphragm, and the one end of diaphragm is connected with the riser perpendicularly, and the other end welding of diaphragm is on sectional inside wall, the through-hole sets up on the riser.
Preferably, the bracket is uniformly welded in a radial shape on the middle part.
The utility model has the advantages that:
the utility model discloses a concrete box girder overhauls people template for hole, each part is connected simply, supports reliably, and overall structure is simple, can prevent that the slurry from getting into the template during concrete placement inside, and the form removal is simple quick, and this template repeatedly usable has avoided overhauing the problem of people's template dismouting difficulty for hole, unable used repeatedly extravagant resource during concrete placement.
The utility model discloses a concrete box girder overhauls people's hole and uses template and support form, support frame are radial arranging, and each support of support frame supports on the inner wall of barrel, and when the barrel outer wall received the pressure of concrete slurry, the support can guarantee can not warp of barrel. The utility model discloses a barrel radius accessible adjusting bolt and nut adjustment can make things convenient for the dismouting on the one hand, and the box girder of the adaptable different specifications of on the other hand overhauls the demand of people's hole size.

Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
example 1
With reference to fig. 1 to 4, a formwork for repairing a manhole of a concrete box girder comprises a cylinder body 1, a support frame 2 and an adjusting bolt 3.
The barrel 1 comprises two sections 4 which are overlapped, L-shaped fixing frames 5 are arranged on the inner side walls of the two sections, through holes 6 are formed in the fixing frames, and the two fixing frames are arranged oppositely.
Adjusting bolt 3 passes through the through-hole and links together two mounts 5, and adjusting bolt's one end threaded connection has nut 7, twists the nut and can draw two mounts to one side or put away, and then tightens up two sections or expandes to change the diameter of barrel 1.
Support frame 2 sets up in the inside of barrel 1, and support frame 2 includes intermediate portion 8, is radial a plurality of supports 9 that are connected with on the intermediate portion, and the front end of support leans on with the inner wall of barrel, provides the support for the barrel.
Specifically, mount 5 includes diaphragm 10, and the one end of diaphragm is connected with riser 11 perpendicularly, and the other end welding of diaphragm is on sectional inside wall, and through-hole 6 sets up on riser 11.
Specifically, the stent is uniformly welded in a radial shape at the middle part, as shown in fig. 3.
As shown in fig. 4, the stent is welded to the middle portion in a radially scattered manner.
Whether the arrangement of fig. 3 or fig. 4 is implemented to provide support for the cartridge as long as the holder is able to rest against the inner wall of the cartridge.
Example 2
The use method of the formwork for the concrete box girder overhauling manholes in the embodiment is disclosed.
A use method of a formwork for overhauling a man hole of a concrete box girder comprises the following steps:
step 1: before the bottom plate of the box girder is poured, the support frame is arranged in the cylinder body, an adjusting bolt and a nut are installed, the adjusting bolt is screwed down, and all supports of the support frame are enabled to be abutted against the inner wall of the cylinder body;
step 2: sand is buried in the cylinder body, and concrete pouring is carried out;
and step 3: and digging out sand when the concrete reaches the age of the detachable formwork, knocking the support frame, taking out the support frame, continuously screwing the nut, tightening the two sections, reducing the radius of the cylinder body, separating the cylinder body from the concrete and taking out the cylinder body, and thus taking out the whole formwork from the concrete.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
