Description

Technical Field

[0001] The utility model relates to a building construction project, and more specifically, to a fireproof and soundproof wallboard for assembled buildings. Background Art

[0002] Prefabricated wall panels are a kind of prefabricated wall material, which has the characteristics of easy installation, energy saving and environmental protection, stable quality, saving time and manpower, etc. Prefabricated wall panels have the advantages of light weight and quick installation, and are widely used in office buildings to separate office spaces.

[0003] In actual production, prefabricated walls usually include steel keels and panels installed on both sides of the keels. In actual production, people usually use gypsum boards with good fire resistance as panels. Since gypsum boards will expand or contract due to changes in temperature and humidity, when installing panels, there will usually be a gap between two adjacent panels. After installation, the panels will be painted and other processes will make the prefabricated wall panels look no different from ordinary walls. At the same time, in order to ensure privacy between tenants, materials with good sound absorption effects such as glass wool are usually filled between the two panels to improve the sound insulation effect of the prefabricated walls.

[0004] In the prior art, the panel is fixed to the keel by self-tapping screws. However, when people use self-tapping screws to fix the panel, they rely on manpower to hold the panel on the keel. When decorating some rooms with high ceilings, the longer panel is not easy to fix, resulting in the need for multiple people to pre-fix the panel, which is time-consuming and labor-intensive.

[0005] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a fireproof and soundproof wall panel for assembled buildings.

[0007] The above technical purpose of the utility model is achieved through the following technical scheme: a fireproof and soundproof wall panel for assembled buildings, including a keel and panels installed on both sides of the keel, the keel is provided with a limit block for limiting the panel on the keel, and long grooves that can be inserted by the limit blocks are formed on both side walls of the keel, and the limit blocks are provided with fixing parts, which are used to fix the limit blocks in the long grooves.

[0008] The utility model is further configured as follows: the limit block includes a mounting portion slidably connected in the long groove and a contact portion for contacting the panel, the mounting portion is provided with a threaded hole, the contact portion is provided with a round hole, a butterfly bolt passes through the round hole, and the butterfly bolt is threadedly connected in the threaded hole.

[0009] The utility model is further configured as follows: a plurality of convex strips are formed on one side of the mounting portion facing away from the bottom wall of the long groove.

[0010] The utility model is further configured as follows: the long groove includes groove one and groove two, the width of groove one is smaller than that of groove two, the contact portion includes a connecting portion located in groove one and a contact piece fixedly connected to the connecting portion, and the diameter of the connecting portion is equal to the width of groove one.

[0011] The utility model is further configured as follows: a sawtooth-shaped friction portion is formed on the side wall of the abutment sheet.

[0012] The utility model is further configured as follows: the width of the long groove is 4 mm to 6 mm.

[0013] The utility model is further configured as follows: the abutment sheet is made of a stainless steel sheet.

[0014] To sum up, the utility model has the following beneficial effects: when installing prefabricated wall panels on floors with higher floor heights, first complete the fixing of the keel, place the panel against the keel, then use the limit block to limit the panel on two adjacent keels, and then use the self-tapping screws to fix the panel to the keel. The panel that is better limited by the limit block is not easy to be skewed in the process of people using self-tapping screws to fix the panel to the keel, thereby eliminating the process of people adjusting the panel. At the same time, the setting of the limit block allows people to align the two ends of the panel with the limit block when pre-installing subsequent panels, which is convenient for the alignment of the panel. The gypsum board has good fire resistance and better guarantees the fire resistance of the panel. The glass wool has good sound absorption performance. Filling the glass wool between the two panels can better absorb the noise when it is transmitted to the glass wool through the panel, thereby better ensuring the sound insulation performance of the prefabricated wall panels.

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] A fireproof and soundproof wallboard for assembled buildings, such as Figure 1As shown, it includes a keel 1, panels 2 installed on both sides of the keel 1 and glass wool filled between the two panels 2. The panels 2 are made of gypsum board. The keel 1 is detachably connected with a limit block for limiting the panel 2 on the keel 1. Long grooves that can be stuck in the limit blocks are formed on the two opposite side walls of the keel 1 facing the panel 2. The limit blocks are provided with fixings, and the fixings are used to fix the limit blocks in the long grooves. When installing assembled wall panels on floors with higher floor heights, first fix the keel 1, lean the panel 2 against the keel 1, then use the limit blocks to limit the panel 2 on two adjacent keels 1, and then fix the panel 2 on the keel 1 with self-tapping screws. The panel 2 with better position limitation is not easy to be skewed when people use self-tapping screws to fix the panel 2 on the keel 1, thus eliminating the process of people adjusting the panel 2. At the same time, the setting of the limit block allows people to align the two ends of the panel 2 with the limit block when pre-installing the subsequent panel 2, so that the edge of the panel 2 is aligned with the keel 1. The gypsum board has good fire resistance and better guarantees the fire resistance of the panel 2. The glass wool has good sound absorption performance. Filling the glass wool between the two panels 2 can better absorb the noise when it is transmitted to the glass wool through the panel 2, thereby better ensuring the sound insulation performance of the assembled wall panel.

[0020] like Figure 1 and Figure 2As shown, the limit block includes a mounting portion 3 slidably connected in the long groove and a contact portion for contacting the panel 2. A threaded hole 4 is provided on the mounting portion 3, and a round hole 5 is provided on the contact portion. A butterfly bolt 6 passes through the round hole 5, and the butterfly bolt 6 is threadedly connected to the threaded hole 4. The thread length of the butterfly bolt 6 is less than the sum of the thickness of the panel 2 and the depth of the long groove. Before using the limit block, the butterfly bolt 6 is first passed through the round hole 5, and then one end of the butterfly bolt 6 is turned into the threaded hole 4. When using the limit block, people can hold the butterfly bolt 6 to move the mounting portion 3 to the desired position, and then rotate the butterfly bolt 6 to make the contact portion contact the panel 2. The setting of the butterfly bolt 6 enables people to have a better force point to move the mounting portion 3 along the long groove. When the mounting portion 3 moves to the desired position, people can press the contact portion against the panel 2 by rotating the butterfly bolt 6. At the same time, the contact portion is pressed against the panel 2 through the threaded connection, so that relative sliding is not easy to occur between the contact portion and the panel 2. , which can better ensure the contact portion to limit the panel 2, the contact portion is L-shaped, the cross-section of the long groove is T-shaped, the long groove includes a groove 7 connected to the surface of the keel 1 and a groove 8 with a width greater than the groove 7, the mounting portion 3 is located in the groove 8 and the thickness of the mounting portion 3 is less than the depth of the groove 8, the contact portion includes a connecting portion 9 located in the groove 7 and a resisting piece 10 welded to the connecting portion 9, the diameter of the connecting portion 9 is equal to the width of the long groove, when people use self-tapping screws to fix a panel 2 on the keel 1, place the other panel 2 against the keel 1, then loosen the butterfly bolt 6, rotate the abutment piece 10 along the screw by hand to rotate the abutment piece 10 to the other panel 2, and then use the butterfly bolt 6 to press the abutment piece 10 against the keel 1. This arrangement makes it unnecessary for people to remove the abutment part from the mounting part 3. The abutment piece 10 can limit the left and right panels 2 connected to the same keel 1 by rotation, which saves people's time.

[0021] like Figure 2As shown in the figure, a serrated friction portion 11 is formed on the side wall of the contact piece 10 facing the keel 1. When the contact piece 10 contacts the panel 2, the surface of the panel 2 made of gypsum material is relatively smooth. When the butterfly bolt 6 is rotated, it is easy to drive the contact piece 10 to rotate together. The setting of the friction portion 11 can better increase the contact area between the contact piece 10 and the panel 2, thereby better avoiding the situation where the rotation of the butterfly bolt 6 drives the contact piece 10 to rotate together. A plurality of convex strips 12 are formed on the side of the mounting portion 3 facing away from the bottom wall of the long groove. In the process of rotating the butterfly bolt 6, when the contact piece 10 contacts the panel 2, the butterfly bolt 6 will generate a force on the mounting portion 3 through the screw rod to move the mounting portion 3 away from the bottom wall of the groove 8. Applying force will make the mounting portion 3 press against the inner wall of the groove 1 7 away from the groove 2 8, and the setting of the convex strip 12 can effectively increase the contact area between the mounting portion 3 and the inner wall of the groove 2 8, so that the mounting portion 3 can be better fixed. The width of the groove 1 7 is 4 mm to 6 mm. When installing the panel 2 made of gypsum, a 4 mm to 6 mm joint needs to be left between adjacent panels 2. The width of the groove 1 7 is set to 5 mm, so that people can make one end of the panel 2 contact with the connecting portion 9 when pre-installing the panel 2, which effectively eliminates the step of measuring the size of the joint. The contact piece 10 is made of stainless steel sheet, which has good strength. The contact piece 10 made of stainless steel sheet can effectively extend the service life of the contact part.
