Description

Slotted gypsum block

Technical Field

The utility model belongs to the building engineering field especially relates to a building gypsum block who accords with the requirement building of fortifying oneself with earthquake.

Background

All the walls of buildings in China, including partition walls, need to take anti-seismic measures, and meet the requirements of anti-seismic design. At present, the mortar joint thickness between an upper building block and a lower building block is controlled between 2 millimeters and 5 millimeters according to the application technical regulations of gypsum building blocks in China, however, according to the requirements of wall anti-seismic measures, horizontal reinforcing steel bars must be placed at intervals in the horizontal direction of a wall body, the diameter of the horizontal reinforcing steel bars is generally between 8 millimeters and 12 millimeters, so that the mortar joint is thickened, and hidden dangers are generated on the quality assurance of the wall body.

In the prior art, the single gypsum block is constructed in such a way that an upwards convex trapezoidal tenon is arranged in the middle of the top of the gypsum block, an inwards concave trapezoidal groove is arranged in the middle of the bottom of the gypsum block, and the trapezoidal groove and the trapezoidal tenon are matched in shape. When the wall is built, the lower trapezoidal groove of the upper gypsum block and the upper trapezoidal tenon of the lower gypsum block can be overlapped up and down, and the bonding gypsum is filled in the mortar joint. But because set up horizontal reinforcing bar between the upper and lower gypsum block, lead to the mortar joint thickening, construction quality is difficult to guarantee, causes adverse effect to the bearing capacity of wall body.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a fluting gypsum block, it has satisfied under the prerequisite that accords with the antidetonation requirement, guarantees wall body construction quality.

The technical scheme of the utility model is that: a top of a slotted gypsum block is provided with an upwards-convex trapezoidal tenon, the bottom of the slotted gypsum block is provided with an inwards-concave trapezoidal groove, and the shapes of the trapezoidal groove and the trapezoidal tenon are mutually matched; the top surface of the gypsum block is respectively provided with a groove along the two sides of the trapezoidal tenon, and the grooves are arranged along the length direction of the gypsum block.

Based on the technical characteristics: the minimum groove width position of the groove is 5 mm to 15 mm; the height of the groove is 5 mm to 15 mm.

The utility model has the advantages that: the utility model discloses product manufacturing process does optimization adjustment on original technology basis, and construction process is more simple and convenient, has satisfied the demand that horizontal reinforcement was laid in grey seam thickness and the antidetonation design simultaneously, has improved the quality of building by laying bricks or stones and wall body quality of gypsum building block.

Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings. These embodiments are provided only for illustrating the present invention and are not intended to limit the present invention.

In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of the 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, which is a vertical sectional view of a gypsum block in the prior art, the top of the gypsum block is provided with an upward convex trapezoidal tenon 1, the bottom of the gypsum block is provided with an inward concave trapezoidal groove 2, the trapezoidal groove 2 and the trapezoidal tenon 1 are mutually matched in shape, and the gypsum block on the upper portion can be vertically overlapped through the trapezoidal groove 2 and the trapezoidal tenon 1. However, because the horizontal steel bars are arranged at the mortar joints between the upper gypsum block and the lower gypsum block, the horizontal steel bars can influence the superposition degree between the upper gypsum block and the lower gypsum block; at the same time, the protruding horizontal steel bars also hinder the filling of the bonding plaster between the trapezoidal groove 2 and the trapezoidal tenon 1.

As shown in fig. 2 and 4, the utility model discloses a fluting gypsum block is on the basis of current gypsum block, is equipped with recess 3 respectively along the both sides of trapezoidal tenon on gypsum block's top surface, and recess 3 arranges along gypsum block's length direction leads to long. As shown in fig. 3, the horizontal steel bar 4 can be placed in the groove 3, and when the upper and lower grooved gypsum blocks are overlapped, the horizontal steel bar is buried in the groove 3, so that the position of the horizontal steel bar can be stabilized, the construction positioning precision is improved, and the construction is convenient; meanwhile, the horizontal reinforcing steel bars 4 buried below cannot influence the filling of bonding gypsum between the upper and lower slotted gypsum blocks.

The cross-sectional shape of the middle groove of the utility model is not limited, and can be round, trapezoid, triangle or other irregular shapes. The groove width of the groove is recommended to be 5 mm to 15 mm at the minimum position; the height of the groove is 5 mm to 15 mm.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
