Description

Three-point bending notched beam mold

Technical Field

The utility model belongs to building die tests field especially relates to a three point bending breach roof beam mould.

Background

Along with the development of the urbanization in China, the population density of cities is higher and higher, the demand of people on houses is more and more urgent, and the high-rise, large-scale and complex degree of buildings are continuously improved. In the civil engineering range, concrete materials occupy an important position, and in actual construction, after concrete is solidified, the surface state is provided with cracks, and the cracks have great influence on the quality safety of a house, so that the method has important significance on the damage research of the concrete, and the accurate crack control cannot be realized in a mold of a general experiment.

Disclosure of Invention

An object of the utility model is to provide a three point bending breach roof beam mould to solve the problem that exists among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a three point bending breach roof beam mould, includes mould and lower mould, it constitutes breach roof beam shaping space to go up mould and lower mould, the upper end intermediate position department symmetry of going up the mould sets up two fixed plates, the inboard middle department of two fixed plates is equipped with the gap, be provided with the baffle in the middle of the gap of two fixed plates, the locating hole has been seted up on the baffle, and the symmetry sets up the both sides at the baffle, and the reference column passes through the locating hole with fixed plate swing joint.

Preferably, the upper end of the baffle is in an arc handle shape, and the lower end of the baffle is in a V-shaped structure.

Preferably, the baffle is vertically arranged in a gap at the inner sides of the two fixing plates, and the width of the baffle is smaller than that of the upper die.

Preferably, the lower die comprises a side die and an end die, the side die and the end die are fixedly connected through bolts, the lower die is connected to the upper die through bolts, and the upper die and the lower die are of rectangular structures.

Preferably, the fixing plate is fixedly connected with the upper die through a bolt.

The utility model has the advantages that:

1. the vertical setting of baffle is in the middle of two fixed plates, can confirm the fissured position of concrete as required when using to can accurate control concrete crack, be provided with the reference column on the baffle, move the reference column position as required and can adjust the downward flexible degree of depth of baffle when the experiment, with this requirement that satisfies different concrete crack depths.

2. The V type structure is set to the baffle bottom, has reduced the resistance for the baffle when using, can easily alternate in the concrete mould, the utility model discloses the cost of manufacture is low, and processing is convenient, and the effect is showing, solves the cracked problem of the unable accurate control breach roof beam of current mould.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-5, a three-point bending notched beam mold comprises an upper mold 2 and a lower mold, the upper mold 2 and the lower mold form a notched beam molding space 3, a notched beam mold is produced in the notched beam molding space 3, two fixing plates 4 are symmetrically arranged at the middle position of the upper end of the upper mold 2, the two fixing plates 4 are fixedly connected with the upper mold 2 through bolts 7, the firmness between the fixing plates 4 and the upper mold 2 is ensured, a gap is reserved at the middle position of the inner sides of the two fixing plates 4, a baffle plate 5 is arranged in the gap between the two fixing plates 4, the width of the baffle plate 5 is smaller than that of the upper mold 2, the baffle plate 5 can freely stretch between the two fixing plates 4 and the upper mold 2, as shown in fig. 5, the length of the baffle plate 5 can be freely adjusted according to actual needs during use, so as to set the depth of a, the locating holes 9 are symmetrically arranged on two sides of the baffle plate 5, the locating columns 6 are connected with the fixing plate 4 through the locating holes 9, and the fixing plate 4 is fixed through the matching of the locating columns 6 and the locating holes 9.

As shown in figure 4, the upper end of the baffle 4 is in the shape of an arc handle, the baffle 4 is taken out by manually picking up the arc handle when in use, the lower end of the baffle 4 is in a V-shaped structure, the resistance of the baffle 4 is reduced when in use, and the depth of a gap can be set more easily.

The lower mould includes side form 8 and end mould 1, and side form 8 and end mould 1 are through bolt 7 fixed connection, have further improved the fastness of lower mould, and the lower mould passes through bolt 7 fixed connection to last mould 2 on, has further improved the fastness of breach roof beam, goes up mould 2 and lower mould and is the rectangle structure, waits to demolish bolt 7 after the concrete sets, can easily take out the mould.
