Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of gypsum board and wall body, concretely to an integrally-formed groove-shaped gypsum board and a keel-free hollow gypsum board wall body. BACKGROUND

[0002] The gypsum board used for building partition walls is mainly paper-faced gypsum board, and its construction method is usually to first erect light steel keels and then rivet the paper-faced gypsum board to the light steel keel frame to form a wall body. Moreover, the mechanical strength of the paper-faced gypsum board is low, the strength of the wall body constructed with the paper-faced gypsum board is low, and the wall body cannot bear heavy objects.

[0003] Some utility model patents connect two layers of gypsum boards together by setting connecting structural members to complete wall construction without light steel keel materials and installation and construction steps of light steel keels, such as the Chinese utility model 202222445272.5 (a hollow purification gypsum board). However, in the existing technical solutions, the manufacturing of the connecting structural members and the production steps of pre-installing the connecting structural members on the gypsum boards are relatively complicated, which increases the production cost of the gypsum boards and the total cost of wall construction. Moreover, since the conventional cast gypsum boards are used, the strength is low, which leads to low strength of the wall body constructed with the gypsum boards.

[0004] In summary, it is a research and development direction of gypsum board walls to develop and produce gypsum boards with low production cost, simple structure, high mechanical strength, and suitable for keel-free installation, and to construct keel-free, low-cost, and high-strength wall bodies by using such gypsum boards. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide an integrally-formed groove-shaped gypsum board and a keel-free hollow gypsum board wall body constructed with the gypsum board to solve the problems of low strength and the need for keel installation of the light steel keel-paper-faced gypsum board wall body in the background technology, and the problems of complicated manufacturing and installation process, high production cost, and low wall body strength of the keel-free gypsum board wall body.

[0006] An integrally-formed groove-shaped gypsum board, which is composed of a gypsum board body and ribs, the ribs are at least two, and the two ribs are arranged on both sides of the gypsum board body and integrally formed with the gypsum board body.

[0007] Further, the ribs are three, the three ribs are uniformly and evenly distributed along the width direction of the gypsum board body, and are integrally formed with the gypsum board body.

[0008] Further, the length of the gypsum board body and the ribs is consistent, the width of the groove-shaped gypsum board is 300mm-900mm, and the length is the same as the height of the wall body to be constructed.

[0009] A no keel hollow gypsum board wall body is composed of a first half wall body and a second half wall body;

[0010] The first half wall body is composed of a plurality of channel-shaped gypsum boards as described above, the plurality of channel-shaped gypsum boards are sequentially distributed in the horizontal direction, and the adjacent two channel-shaped gypsum boards are connected and fixed through the first fixing member;

[0011] The second half wall body includes a plurality of channel-shaped gypsum boards as described above and two longitudinal 1 / 2 channel-shaped gypsum boards, the plurality of channel-shaped gypsum boards are sequentially distributed in the horizontal direction and are distributed in a 1 / 2 staggered manner corresponding to the channel-shaped gypsum boards of the first half wall body, and the two longitudinal 1 / 2 channel-shaped gypsum boards are distributed on both sides of the plurality of channel-shaped gypsum boards; the channel-shaped gypsum boards and the longitudinal 1 / 2 channel-shaped gypsum boards in the second half wall body are connected and fixed on the channel-shaped gypsum boards of the first half wall body through the second fixing member.

[0012] Further, the first fixing member and the second fixing member are self-tapping screws.

[0013] Further, the diameter of the self-tapping screw is 4mm.

[0014] The technical scheme provided by the utility model has the beneficial effects that:

[0015] (1) Compared with the existing light steel keel-paper faced gypsum board wall body, the no keel hollow gypsum board wall body of the utility model does not need to use light steel keel materials and does not need to install keels, so that the keel material cost, installation cost and construction period can be saved, and the total cost of wall body construction is reduced;

[0016] (2) The existing gypsum board with a prefabricated connecting structure without keel installation and the existing paper faced gypsum board (the bending strength is about 3MPa) with light steel keel installation usually adopt casting production technology, and the strength of the gypsum board itself is low; the utility model adopts pressing forming technology, and the rib increases the strength, so that the strength of the obtained channel-shaped gypsum board is high (the bending strength is greater than 10MPa);

[0017] (3) The existing gypsum board wall body with a prefabricated connecting structure without keel installation and the existing light steel keel-paper faced gypsum board wall body are limited by the low strength of the gypsum board itself, and the hanging force of the wall body is low, and heavy objects cannot be hung in general; compared with the above, the bending strength of the channel-shaped gypsum board in the no keel hollow gypsum board wall body of the utility model is greater than 10MPa, and the corresponding hanging force can reach 1000N (about 100kg), and heavy objects can be hung;

[0018] (4) The existing hollow gypsum board wall without keels requires the manufacture of special connecting structural parts, which are then pre-installed on the gypsum board. The production process is relatively complicated, which increases the production cost of the gypsum board and the total cost of the wall construction. However, the grooved gypsum board described in the present invention has a simple structure and is easy to produce. It only needs to be pressed and formed into a grooved gypsum board once to realize the keel-free installation and construction of the wall, thereby reducing the production cost of the gypsum board and the construction cost of the wall.

Since the groove-shaped gypsum board 100 in the utility model adopts compression molding technology, the density of the gypsum board can be improved, and the mechanical strength of the gypsum board is further improved. Moreover, the several ribs 20 formed on the gypsum board by synchronous compression molding help to further increase the mechanical strength of the gypsum board, so that the obtained groove-shaped gypsum board 100 has high folding strength. The width of the groove-shaped gypsum board 100 is 300mm-900mm, and the length is the same as the height of the wall to be built, so that the technical effect of one-time wall building from the wall bottom to the wall top by using one groove-shaped gypsum board 100 is realized. Correspondingly, the length of the rib 20 is consistent with the length of the gypsum board body 10.

[0027] The groove-shaped gypsum board 100 of the utility model has a folding strength greater than 10MPa, and the corresponding hanging force can reach 1000N (about 100kg), and heavy objects can be hung. The rib 20 structure enhances the strength of the groove-shaped gypsum board 100, and further improves the strength performance of the groove-shaped gypsum board 100.
