Abstract

The invention provides a simple tool and a simple method for testing wall perpendicularity, belongs to the technical field of building construction and relates to a design technique of auxiliary tools. The simple tool is characterized in that a plumb bob is cone-shaped, a hook is arranged at the center of a circle plane and fastened with a suspension line, and the other end of the suspension line is tied on a groove of a short arm of an L-shaped wooden block frame. The L-shaped wooden block frame is formed by mutual perpendicular fastening of ends of a short wooden block and a long wooden block; the groove of the short arm is a shallow groove carved in the short arm. The method includes the steps: producing a shear wall formwork, handholding a long arm of the simple tool, cling the free end of the short arm to the surface of the formwork, measuring sizes of the plumb bob and the formwork surface by a measuring tape or straight rule, comparing measuring values and judging perpendicularity. The simple tool and the simple method have the advantages that the problem of low perpendicularity control efficiency of shear formworks in construction site is solved, quality control reaches a new level, and the simple tool is conveniently made of local materials in the construction site, and is reusable and cost-saving.

Description

A kind of light instrument of body of wall verticality and its method checked

Technical field

Belong to the construction quality construction field, a kind of technical design of control construction quality when exactly relating to building main body construction.

Background technology

According to " concrete structure engineering construction quality acceptance specification " GB50204-2002(2011 version) regulation, the verticality acceptance criteria of shear wall moulding concrete is [0,8], in order to reach this acceptance criteria, we need before concrete is built shear wall formwork to be inspected for acceptance, be directly to carry out the messenger wire inspection with plumb bob in the past, and generally will cooperate with two people: people is ceiling hammer in the above, also will measure distance accurate and wall form; Another person not only will command top people to cooperate below, also will measure the distance of plumb bob and wall form exactly; Checking efficiency is low.If item inspection personnel can not fully be equipped with, just can't satisfy the requirement of inspecting for acceptance, construction quality can not well be controlled, and how to improve inspection speed, raise the efficiency, and finally to control construction quality is the problem that we inquire into always.

Summary of the invention

The invention provides a kind ofly in the building main body construction process, can be fast carry out a kind of light instrument of body of wall verticality and its method checked that verticality is inspected for acceptance to shear wall formwork.

The technical scheme that the present invention takes:

A kind of light instrument of checking the body of wall verticality comprises plumb bob, and its scheme is: plumb bob is cone shape, has hook and messenger wire one end fastening at the center of disk, and the other end of messenger wire ties up on the groove of L type lumps of wood support body galianconism; Described L type lumps of wood support body is that the end is orthogonal separately fasteningly constitutes by a short lumps of wood and rectangular wood; The groove of described galianconism is that the galianconism free end plays the 300mm place, by a shallow grooves of graduating with cutter; Described galianconism, preferred 400 mm of its length; Described rectangular wood, be called long-armed, preferred 2200 mm of its length; Described lumps of wood preferred size is 40 * 40 mm of unit.

A kind of simple and easy method of checking the body of wall verticality, implement by following operation steps:

1) make shear wall formwork,

2) get the light instrument of checking the body of wall verticality,

3) hand-held light instrument is long-armed,

4) the galianconism free end is close to the shear wall formwork surface,

5) measured the size of plumb bob and template face by tape measure or ruler,

6) measured value and 300mm are compared, judge the verticality of metope.

Good effect behind enforcement the present invention is:

Solved the low problem of working-yard shear wall formwork verticality control efficiency, made quality control rise to a new step, and the making of gathering materials on the spot of light instrument convenient construction scene, reusable, also saved cost.

Embodiment

Now the invention will be further described by reference to the accompanying drawings

A kind of light instrument of checking the body of wall verticality comprises plumb bob, and its formation is: plumb bob 3 is cone shapes, has hook and messenger wire one end fastening at the center of disk, and the other end of messenger wire ties up on the groove of L type lumps of wood support body galianconism 1; Described L type lumps of wood support body is that the end is orthogonal separately fasteningly constitutes by a short lumps of wood and rectangular wood; The groove of described galianconism 1 is that the galianconism free end plays the 300mm place, by a shallow grooves of graduating with cutter; Described galianconism, preferred 400 mm of its length; Described rectangular wood, be called long-armed 2, preferred 2200 mm of its length; Described lumps of wood preferred size is 40 * 40 mm of unit.

1) make shear wall formwork,

2) get the light instrument of checking the body of wall verticality,

3) hand-held light instrument is long-armed 2,

4) galianconism 1 free end is close to the shear wall formwork surface,

5) measured the size of plumb bobs 3 and template face by tape measure or ruler 4,

6) measured value and 300mm are compared, judge the verticality of metope.
