Abstract
The utility model discloses an it establishes structure to be used for reinforced (rfd) plank sheathing of concrete column to prop up, the characterized by plank sheathing is formed by the concatenation of little template, the plank sheathing sets up the recess being connected the position with the steel sheet, set up the recess in the middle of the plank sheathing, installation steel side pipe in the recess, steel side's pipe cross -section length and width are 30~40cm, steel side's pipe leads to long arranging along the plank sheathing, steel side's pipe of every little template is at check valve of tip installation, the plank sheathing outside sets up the template hoop, the template hoop is 40~50cm along the interval of direction of height, the template hoop is linked to be whole with steel sheet and plank sheathing.
Description
Technical field
This utility model relates to a kind of plank sheathing and installs structure, installs structure particularly to a kind of plank sheathing for reinforcement of concrete post.
Background technology
When there are the common quality defects such as honeycomb hole when concrete column, bearing capacity can be a greater impact, it is necessary to concrete column is reinforced the bearing capacity improving concrete column.The method of tradition reinforced concrete disease post has steel plate reinforcement, namely arrange steel plate in concrete weak post surrounding to reinforce, casting concrete between steel plate and concrete weak post, owing to after-pouring concrete and original concrete deformation are inconsistent, differ greatly additionally, due to steel plate and concrete rigidity, when stress be no matter steel plate and after the concrete that adds be difficult to play a role, consolidation effect is severely impacted.For this situation, it is possible to adopt and reinforced concrete is carried out precompressed.Adopt as follows at casting concrete front template erection method: the steel plate template directly as casting concrete is installed in side by two of concrete column, and another two side adopts plank sheathing.But how to ensure the problem that the reliable and stable engineering staff of being of plank sheathing faces.
Utility model content
This utility model is to provide a kind of plank sheathing for reinforcement of concrete post and installs structure, solves the reliable and stable unwarrantable problem of plank sheathing.
In this utility model, plank sheathing thickness is 18～25mm, and plank sheathing is formed by little template splicing, and every piece little form height is 50～70cm.Plank sheathing is arranging groove with steel plate connecting portion, and recess width is 10～15cm, and depth of groove is 8～10mm.Groove is set in the middle of plank sheathing, installing steel square tube in groove, steel Box Section length and width is 30～40cm, and steel square tube is along the elongated layout of plank sheathing, the steel square tube of each little template installs a Non-return air valve in end, and Non-return air valve is in order that be easy to each little template segmentation and remove.
Owing to reinforced concrete is subject to precompressed in condensation process, plank sheathing and reinforced concrete bonding ratio are stronger, plank sheathing is difficult to dismounting, therefore this utility model arranges steel square tube in the middle of plank sheathing, be conducive to removing plank sheathing after reinforcing concrete curing age reaches, dismounting plank sheathing is that reinforced concrete is produced lateral pressure by steel square tube, so that plank sheathing separates with reinforced concrete by realizing in the ventilation of steel square tube.
Arranging template hoop outside plank sheathing, template hoop is 40～50cm along the spacing of short transverse, and steel plate and plank sheathing are linked to be entirety by template hoop.
This utility model is easy to operate.
Accompanying drawing explanation
Fig. 1 is that the plank sheathing for reinforcement of concrete post installs structural representation.
In each accompanying drawing: 1, plank sheathing, 2, Non-return air valve, 3, steel square tube, 4, template hoop.
Detailed description of the invention
Fig. 1 is that the plank sheathing for reinforcement of concrete post installs structural representation.
In embodiment, plank sheathing 1 thickness is 18～25mm, and plank sheathing 1 is formed by little template splicing, and every piece little form height is 50～70cm.Plank sheathing 1 is arranging groove with steel plate connecting portion, and recess width is 10～15cm, and depth of groove is 8～10mm.In the middle of plank sheathing 1, groove is set, steel square tube 3 is installed in groove, steel square tube 3 cross-sectional length and width are 30～40cm, steel square tube 3 is along the elongated layout of plank sheathing 1, the steel square tube 3 of each little template installs a Non-return air valve 2 in end, and Non-return air valve 2 is in order that be easy to each little template segmentation and remove.Arranging template hoop 4 outside plank sheathing 1, template hoop 4 is 40～50cm along the spacing of short transverse, and steel plate and plank sheathing 1 are linked to be entirety by template hoop 4.
