Abstract

The utility model discloses a guide wall structure for a top-stitched seam among fair-faced concrete layers. The guide wall structure comprises a reinforced concrete wall body and is characterized in that one surface of the outer side of the reinforced concrete wall body, relative to a floor slab, is provided with a step-shaped guide wall which is higher than the upper kin of the floor slab, the thickness of the root part of the guide wall is equal to that of the reinforced concrete wall body, the thickness of the top of the guide wall is 1/3-1/5 that of the reinforced concrete wall body, and the guide wall and the reinforced concrete wall body are poured into a whole. The utility model aims at solving the problem that a horizontal construction seam is not matched with the top-stitched seam due to integral pouring by using the method that the outer wall body horizontal construction seam is identical to the horizontal top-stitched seam remained in the design, and the requirement that a concrete beam and the wall body construction seam are remained in a region where the shearing force value is not the maximum is met.

Description

Clear-water concrete interlayer outseam is led wall construction

Technical field

The utility model relates to a kind of clear-water concrete and leads wall construction.

Background technology

Clear-water concrete is claimed ornamental concrete again, gains the name because of it has decorative effect.It belongs to one-time cast-forming; Do not do any outer decoration; A kind of nature decorative cover that is directly made up by outseam, buddhist seam and the split bolt hole etc. of skin texture, texture and the well-designed construction of main structure body concrete itself and form, surfacing is smooth, color and luster is even, corner angle are clearly demarcated, no clashing and breaking and pollution.Because clear-water concrete is very high to construction process requirement, therefore the construction with ordinary concrete is very different.Outseam is the clear-water concrete integral surface to be carried out piecemeal handle, thereby reaches building structure and the unified building technology of decorative appearance art.Monobloc cast has some unfavorable factors, and wherein the clear-water concrete metope is built after the completion, and the horizontal construction joint of outer body of wall can be stayed on the metope inevitably, influences outseam carries out lattice and decoration to the wall surface function.

The utility model content

The purpose of the utility model provides a kind of clear-water concrete interlayer outseam and leads wall construction; The horizontal outseam that outer body of wall horizontal construction joint and design are kept somewhere matches; Solve the inharmonic problem of horizontal construction joint and outseam position that monobloc cast brings, satisfy concrete beam and wall construction seam simultaneously and be retained in the maximum shear value with exterior domain.

For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of clear-water concrete interlayer outseam is led wall construction, comprises reinforced concrete wall, it is characterized in that: said reinforced concrete wall is having the stair-stepping wall of leading with respect to floor outside one side; The said wall of leading is higher than the floor epithelium; The thickness of leading the foot of a wall portion equals the thickness of reinforced concrete wall, and the thickness of leading the wall top is the thickness of 1/3～1/5 reinforced concrete wall, saidly leads wall and reinforced concrete wall is cast for one.

Said thickness of leading the wall top is 50mm.

Compared with prior art the utlity model has following characteristics and beneficial effect:

One, the utility model has overcome the shortcoming that exterior wall horizontal construction joint that traditional clear water concrete wall monobloc casts brings influences the outseam function;

Two, the job practices of the utility model does not influence the monobloc cast effect of beam and wall, optimizes the beautiful decoration property of fair-faced concrete outer wall outseam, economy, easy construction.

The specific embodiment

Embodiment is referring to Fig. 4; A kind of clear-water concrete interlayer outseam is led wall construction, comprises reinforced concrete wall, it is characterized in that: said reinforced concrete wall 1 is having the stair-stepping wall 2 of leading with respect to floor outside one side; The said wall of leading is higher than floor epithelium 15; The thickness of leading wall 2 roots equals the thickness of reinforced concrete wall 1, and the thickness of leading wall 2 tops is the thickness of 1/3～1/5 reinforced concrete wall 1, and the said wall 2 of leading is cast for one with reinforced concrete wall 1.Said thickness of leading wall 2 tops can be selected 50mm.

The job practices that this clear-water concrete interlayer outseam is led wall construction is referring to Fig. 1-Fig. 7, and step is following:

Step 1, wall, beam form: put the wall form line and prop up and take lower floor's exterior sheathing 8 and lower floor's inner formword 7, lower floor's exterior sheathing 8 is inboard solid

Outseam bar 3 is arranged surely, and outseam bar 3 is higher than concrete building plated construction epithelium 70mm; Prop up and take beam bottom board plate 6, beam bottom board plate 6 and lower floor's inner formword 7 overlap joints;

Step 2, the colligation of beam muscle;

Step 3, fixing guide wall form board 4: with respect to lower floor's exterior sheathing 8 inboards, fast easy-to-closing net 5 one ends are solid in a zigzag at the metal right angle

Fix on guide wall form board 4 bottoms, the other end is fixed on beam bottom board plate 6 and lower floor's inner formword 7 lap-joints, and guide wall form board 4 and beam bottom board plate 6 are linked into an integrated entity; Lower floor's exterior sheathing 8, guide wall form board 4 and lower floor's inner formword 7 form a stepped space;

Building of step 4, lower floor's walls concrete: in stepped space, the even concreting of level lower floor body of wall outseam

Bar 3 places, the height of the concrete guide wall 2 of formation is concordant with outseam bar 3, leads the wall end face and forms wall outside horizontal construction joint;

Building of step 5, beam, plate: take slab form and side template, remove guide wall form board 4, vertical perpendicular to the beam of body of wall

Constuction joint is stayed 20cm～30cm in the bearing, and the colligation floor bar is treated the reinforcing bar acceptance(check), and the concrete one-time-concreting completion of floor and beam is to floor with beam is protected and maintenance;

Step 6, upper strata body of wall formwork: pull down layer exterior sheathing 8, upper strata exterior sheathing bearing device is installed, said upper walls template support

The Unit Installation method is following; The outside of being close to upper strata body of wall 10 is provided with at interval and connects high carriage 12, and the said high carriage 12 that connects is bracket shape steel part, and there is a L shaped saddle upper end of bracket shape steel part; Place elongated flitch 11 in the L shaped saddle; Every connects high carriage 12 and is fixed by split bolt and lower floor's body of wall, and said connecing between high carriage 12 and the lower floor's exterior surface of wall is lined with backing plate 14, and lower floor's body of wall inner surface and split bolt corresponding position are lined with cushion block;

Reinforcing bar in step 7, the colligation upper strata body of wall;

Step 8, upper strata inner formword 19 is supported on the floor, upper strata exterior sheathing 9 is supported on the exterior sheathing bearing device of upper strata;

Building of step 9, upper walls body concrete: concreting upper strata body of wall 10, the concrete construction joint of two-step pouring and wall outside outseam match;

Step 10, body of wall is protected and maintenance.
