(3) paste the sponge strip method:
The method is present the most frequently used method, and it is sponge strip of stickup first artificial on the concrete face of bottom concrete joint part, and then installs upper former, to reaching the not purpose of spillage.But also there are a lot of drawbacks in the method: at first, owing on the concrete face floating dust being arranged, sponge strip generally is pasted not strongly, at formwork or when building concrete, and the easy local shedding of sponge strip, thus cause spillage, can not guarantee to connect a batch quality fully.Secondly, during the out-of-flatness of concrete face sponge strip be not easy to paste straight, thereby impact connects the attractive in appearance of stubble.Again, after concrete was built and finished, sponge strip is easy-clear not, simultaneously, pasted, removed sponge strip and need to expend certain artificial and material.
Summary of the invention
In order to solve faulting of slab ends, spillage that concrete structure joint part in the prior art exists, to connect the not straight technical problem of stubble, the purpose of this invention is to provide the flexible tongue and groove joint stubble of a kind of concrete job practices, utilize the method to carry out the concrete structure and connect the stubble construction, can effectively solve faulting of slab ends, spillage that concrete structure joint part exists, connect the not straight technical problem of stubble, guarantee the quality of concrete structure joint part.After construction is finished, form a beautiful recessed band at joint part, straight, attractive in appearance.
To achieve these goals, the invention provides the flexible tongue and groove joint stubble of a kind of concrete job practices, may further comprise the steps:
Step 2 is carried out the bottom concrete and is built, build finish after, certain distance in the wood lath wedging bottom concrete member;
Step 3, bottom concrete are dismantled template after building and finishing certain hour, are formed the tongue and groove of " L " type by described wood lath at the joint part of bottom concrete member;
Step 4, the thicker elongated elastic sealing strip of thickness of an above-mentioned wood lath of Thickness Ratio of the sticking nail in the bottom of the template under dismounting;
Preferably, described elastic sealing strip is rubber strip.
Preferably, the thickness of described wood lath is 3mm.
Preferably, the thickness of described rubber strip is 6mm.
Preferably, described wood lath is three-ply board.
The invention has the beneficial effects as follows:
1, bottom concrete member has been reserved tongue and groove, increased the spatial accommodation of elastic sealing strip, it is poorly sealed that the template that can avoid causing because of concrete face deviation is pressed onto the inclined to one side recess weather strip of elastic limit concrete face with weather strip, thereby cause the phenomenon of spillage, guaranteed the pouring quality of joint part concrete.
2, weather strip in advance sticking nail on template, both guaranteed the straight of weather strip, be unlikely to again partially recessed because of concrete face part, make template applying defective tightness and cause weather strip to come off.
3, the wood lath of the method and weather strip all are fixed on the template, can have enough to meet the need use, and be time saving and energy saving, saves cost.
4, after application the method is finished construction, form a beautiful recessed band at two-layer concrete face joint part, straight, attractive in appearance.
