In order to achieve the above purpose, the technical scheme of the utility model is that:
the utility model provides an underground continuous wall surpasses pouring concrete repeatedly usable's template, includes the fixed die plate, its characterized in that: still include shaped steel template, many connecting reinforcement, connecting reinforcement welded fastening be in on the shaped steel template, per two connecting reinforcement symmetry welded fastening are in shaped steel template's both sides, the gap between two connecting reinforcement forms the draw-in groove, inserts the fixed die board in the draw-in groove, makes shaped steel template and fixed die board be connected.
Furthermore, the section steel template is made of I-shaped steel with the length of 1.2m and the width of 0.8 m.
Furthermore, every two connecting steel bars are symmetrically welded and fixed on two surfaces of the web plate of the section steel template in a group.
Furthermore, a semicircular notch is formed in the middle point of the upper edge of the profile steel template.
Furthermore, a lifting hole is formed above the section steel template.
The utility model has the advantages that:
the utility model provides a be used for secret diaphragm wall to surpass pouring concrete placement repeatedly usable's template can accelerate form setting efficiency, saves a large amount of timber templates again, saves the process of consolidating the installation template to constrictive space with the manual work, simple manufacture, convenient operation, the cost is low, the dependable performance, the installation rate is fast, constructor easily masters, the efficiency of construction of ground side wall concrete can be improved greatly.

fig. 2 is a top view of the present invention;
fig. 3 is a left side view of the present invention;
fig. 4 is a perspective view of the present invention.
In the figure, 1-semicircular gap, 2-lifting hole, 3-connecting reinforcing steel bar, 4-section steel template, 5-fixed template, 6-web plate and 7-underground continuous wall concrete pouring pit foundation.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will make a detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
As shown in fig. 1-4, the reusable formwork for the concrete super-grouting part of the underground diaphragm wall comprises a fixed formwork 5, a profile steel formwork 4 and a plurality of connecting steel bars 3, wherein the connecting steel bars 3 are welded and fixed on the profile steel formwork 4, every two connecting steel bars 3 are symmetrically welded and fixed on two sides of the profile steel formwork 4, a slot is formed in a gap between the two connecting steel bars 3, and the fixed formwork 5 is inserted into the slot, so that the profile steel formwork 4 is connected with the fixed formwork 5 (the fixed formwork is the fixed formwork for the concrete super-grouting reinforcement cage of the underground diaphragm wall).
Preferably, the section steel template is made of I-shaped steel with the length of 1.2m and the width of 0.8 m.
Preferably, every two connecting steel bars 3 are symmetrically welded and fixed on two sides of a web plate 6 of the section steel template 4, and the two connecting steel bars 3 are welded on the section steel template 4. The length of the connecting steel bar is 55cm, the diameter of the connecting steel bar is 25mm, and the length of the connecting steel bar welded with the section steel template is 25cm.
Preferably, a circular notch 1 with the radius of 5cm is dug at the middle point of the upper edge of the section steel template 4 to serve as a placing space for the steel wire rope of the lifting hook and the lifting ring.
Preferably, a lifting hole 2 with the diameter of 3cm is dug under the notch above the section steel template, and the lifting hook can be used for lifting.
Before the steel bar cage fixing device is used, a manufactured steel bar mold is cleaned, demolding oil is brushed on the steel bar mold, a crane lifting ring penetrates into a lifting hole, a steel wire rope sleeve penetrates through the lifting ring and is placed in a gap, the steel wire rope sleeve is lifted by a crane, two persons hold the steel wire rope to be aligned, the steel wire rope sleeve is aligned with a fixing template and is put down, the clamping groove clamps the fixing template, and the front portion and the rear portion of the clamping groove are aligned with the fixing template of a steel bar cage (the top end of the fixing template of the steel bar cage is placed on the steel bar template). Because the draw-in groove has fixed shaped steel template's left and right sides displacement and front and back displacement, shaped steel template's dead weight has controlled fixed die plate's come-up, and then guarantees that underground continuous wall surpasses to irritate partial concrete and not excessive, can fully vibrate, guarantees the quality of pouring of concrete. And after the initial setting of the concrete is finished, directly hoisting the section steel template by using a crane.
Adopt the utility model discloses but reuse's shaped steel template can accelerate formwork erection efficiency, saves a large amount of timber formworks again, saves the process of consolidating the installation template to constrictive space with the manual work, and then improves formwork erection's efficiency.
