Abstract
The utility model discloses a structure that back pouring roof beam reserved hole was handled in bulky concrete, it is equipped with reservation hole (2) of back pouring roof beam section (3) in thick wall (1) of bulky concrete, top of reserving hole (2) is equipped with grout pipe (4), back pouring roof beam section (3) are pour and are accomplished the back, the one end of grout pipe (4) is buried and is pour in back in roof beam section (3) and insert to reserve hole (2) at the bottom, the other end kickup is exposed outside back pouring roof beam section (3). The utility model discloses a this kind of reserve hole and bury arrangement structure type economy of grout pipe underground is feasible, and structural integrity is good, and the construction degree of difficulty is less, and the cost is lower, has wide application prospect.
Description
Technical field
The utility model relates to Hydraulic and Hydro-Power Engineering technical field, particularly relates to the structure of after-pouring beam reserving hole process in a kind of concrete in mass (thick wall).
Background technology
In hydraulic structure, there is the structure of beam, due to many reasons, need the construction carrying out beam after massive concrete walls body concrete has been constructed again, for strengthening structural integrity, improve reliability of structure, need by girder construction according to stressed pattern in concrete preformed hole hole out in massive concrete walls body construction process.The processing method traditional to reserving hole is reserving hole in concrete in mass, carries out building of concrete beam; This situation easily causes beam inner concrete to fill secret room, affects the force structure of beam, there is potential safety hazard; Or reserving hole is more shallow, anchorage length of steel bar is inadequate, cannot meet structural requirement.
Utility model content
The purpose of this utility model is for solving the deficiencies in the prior art, providing the structure of after-pouring beam reserving hole process in a kind of concrete in mass.
This method is achieved by following technical solution:
It is the reserving hole being provided with after-pouring beam section in the thick wall of concrete in mass, grout pipe is provided with above reserving hole, after after-pouring beam section has been built, one end of grout pipe to be imbedded in after-pouring beam section and is inserted at the bottom of reserving hole, and the other end is bent upwards exposure outside after-pouring beam section.By pre-embedment grouting pipe, after after-pouring beam section has been built, make filling in reserving hole closely knit by grouting, improve reliability of structure.
The height of reserving hole is highly identical with after-pouring beam section, the width 0 ~ 10cm wider than after-pouring beam section of reserving hole.The degree of depth of reserving hole should be more than or equal to the anchorage length of steel bar of regulation and stipulation.Reserving hole inside should after concrete initial set dabbing.Need in reserving hole by the assembling reinforcement of specification anchorage length.Reserving hole is built as after-pouring beam section simultaneously.
The beneficial effects of the utility model are:
This reserving hole of the present utility model buries the arrangement pattern economically feasible of grout pipe underground, and structural integrity is good, and difficulty of construction is less, and cost is lower, has broad application prospects.
Accompanying drawing explanation
Fig. 1 is reserving hole structural representation;
Fig. 2 be grout pipe is set and complete after-pouring beam section build after structural representation.
The thick wall of description of reference numerals: 1-, 2-reserving hole, 3-after-pouring beam section, 4-grout pipe, reinforcing bar in 5-beam.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
See Fig. 1, the utility model after concrete in mass, wall 1 arranges reserving hole 2 for solving, and is connected with the good of after-pouring beam section 3 to realize rear wall 1.As shown in Figure 2, the utility model, by arranging grout pipe 4 above reserving hole 2, like this after after-pouring beam section 3 has been built, is in the milk by the position of grout pipe 4 to former reserving hole 2 with the stability improving structure.After after-pouring beam section 3 has been built, a part for grout pipe 4 is buried in wherein, position at the bottom of one end straight cutting to the hole of reserving hole 2, and the other end is bent outwardly exposure outside after-pouring beam section 3 outside reserving hole 2.
As shown in the figure, this method is mainly carried out in accordance with the following steps:
The first step, installs the template of reserving hole 2 while installing concrete in mass thick wall 1 template;
Second step, completes the template that rear dismounting reserving hole 2 periphery built by the thick wall of concrete in mass 1, in reserving hole 2 periphery dabbing after initial set;
3rd step, reinforcing bar 5 in the beam laying after-pouring beam section 3 in reserving hole 2, buries grout pipe 4 underground;
4th step, builds after-pouring beam section 3, is in the milk after after-pouring beam section 3 concrete reaches design strength by grout pipe 4.
More than just embody rule example of the present utility model, the technical scheme that the utility model also has other embodiment, all employings to be equal to replacement or equivalent transformation to be formed, all drops within the protection domain required by the utility model.
Claims (1)
1. the structure of after-pouring beam reserving hole process in a concrete in mass, it is included in the reserving hole (2) being provided with after-pouring beam section (3) in the thick wall (1) of concrete in mass, it is characterized in that: be provided with grout pipe (4) in the top of reserving hole (2), one end of grout pipe (4) to be imbedded in after-pouring beam section (3) and is inserted to reserving hole (2) end, and the other end is bent upwards exposure outside after-pouring beam section (3); The height of described reserving hole (2) is highly identical with after-pouring beam section (3), the width 0 ~ 10cm wider than after-pouring beam section (3) of reserving hole (2).
