Description

Technical Field

[0001] The utility model relates to a glass fiber reinforced resin profile door and window attached frame structure, belonging to the technical field of building decoration. Background Art

[0002] With the increasing requirements for energy-saving of doors and windows, the thermal bridge problem during door and window installation has become an important issue affecting the performance of doors and windows.

[0003] The solution to this problem is to use external hanging doors and windows or to install doors and windows with energy-saving attached frames. Usually, external hanging doors and windows have the disadvantages of high cost and inconvenience in construction. Therefore, the energy-saving attached frame installation method of doors and windows has significant advantages and is gradually being widely accepted.

[0004] When glass fiber reinforced resin profiles are used as door and window frames, the profile's nail holding force is only 600 N / mm. For example, for a 3mm thick profile, the nail holding force is 1800 N. If screws are fastened multiple times in the same position, the nail holding force will decrease.

[0005] When the auxiliary frame is installed in the wall hole and the main frame is installed on the auxiliary frame, the auxiliary frame needs to provide sufficient nail holding force. Insufficient nail holding force will cause the screw connection to fail, and there will be safety hazards in the installation of doors and windows.

[0006] Therefore, there is an urgent need in the art for a glass fiber reinforced resin profile door and window frame structure that can provide sufficient nail holding force. Summary of the Invention

[0007] The purpose of the utility model is to solve the problem of low nail holding force of glass fiber reinforced resin profiles in the prior art.

[0008] In order to achieve the purpose of solving the above problems, the technical solution adopted by the present invention is to provide a glass fiber reinforced resin profile door and window auxiliary frame structure, including a glass fiber reinforced resin profile, and the cavity inside the glass fiber reinforced resin profile is respectively provided with an inner lining steel and a thermal insulation material for increasing the nail holding force of the auxiliary frame.

[0009] Preferably, a partition is provided in the cavity inside the glass fiber reinforced resin profile, dividing the cavity into two parts, one part is provided with the inner lining steel material, and the other part is provided with the thermal insulation material.

[0010] Preferably, the partition is a reinforcing rib.

[0011] Preferably, the inner wall of the glass fiber reinforced resin profile is provided with a protrusion for positioning the lining steel.

[0012] Preferably, the outer surface of the glass fiber reinforced resin profile is provided with a reinforced glass fiber felt cloth for improving the impact resistance of the resin auxiliary frame.

[0013] Preferably, the square steels are intermittently arranged in the glass fiber reinforced resin profile cavity according to the positions of the fixing screws, the length of the square steels is 50-300 mm, the spacing distance is 300-600 mm, and the gaps are filled with thermal insulation material.

[0014] Preferably, the thermal insulation material is polyurethane foam or polystyrene foam.

[0015] Preferably, in the glass fiber reinforced resin profile, the resin is polyurethane resin, epoxy resin or polyester resin.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The utility model provides a structure that can enhance the nail holding force of the glass fiber reinforced resin auxiliary frame. The inner lining steel material is used to increase the nail holding force of the auxiliary frame profile, solving the problem of insufficient nail holding force when the steel sheet on the auxiliary frame is fixed and the main frame is installed on the auxiliary frame.

[0024] In order to make the present invention more clearly understood, preferred embodiments are described in detail with reference to the accompanying drawings as follows:

[0025] like Figure 1-5As shown, the present invention provides a structure for enhancing the nail-holding strength of a glass fiber reinforced resin auxiliary frame, comprising a glass fiber reinforced resin profile 1. The cavity within the glass fiber reinforced resin profile 1 is provided with a lining steel 2 and a thermal insulation material 3, respectively, for enhancing the nail-holding strength of the auxiliary frame. The outer surface of the glass fiber reinforced resin profile 1 is provided with a reinforcing glass fiber felt 4 for improving the impact resistance of the resin auxiliary frame.

[0026] As attached Figure 3 As shown, a glass fiber reinforced resin auxiliary frame structure provided by the utility model includes a glass fiber reinforced resin auxiliary frame profile and an inner lining steel profile.

[0027] When the auxiliary frame is installed in the opening, the fixing screws of the installation steel sheet are fixed to the glass fiber reinforced resin profile 1 and the lining steel 2 at the same time. The presence of the lining steel 2 effectively increases the nail holding force of the auxiliary frame and can effectively fix the installation steel sheet.

[0028] When the main frame is fixed to the glass fiber reinforced resin auxiliary frame structure, the screws are fixed to the glass fiber reinforced resin profile 1 and the lining steel 2, which also increases the nail holding force of the auxiliary frame and effectively fixes the main frame of the door and window.

[0029] As attached Figure 4 As shown, the fiberglass-reinforced resin auxiliary frame structure is connected to the wall in the same manner, but the main frame is secured to the auxiliary frame via door and window mounting connectors. This is suitable for on-site installation of pre-glazed doors and windows. The fiberglass-reinforced resin profile 1 and the inner lining steel 2 are secured using door and window mounting connectors and screws. This installation method particularly tests the auxiliary frame's pull-out resistance when the door and window are subjected to positive wind pressure.

[0030] As attached Figure 5 As shown, the auxiliary frame is connected to the wall in the same way, but the main frame profile has burrs. When installing doors and windows, the main frame can be directly fixed to the auxiliary frame with screws. This installation method is suitable for whole window installation.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form or substance. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the present invention, and these improvements and supplements should also be considered as the scope of protection of the present invention. Any technician familiar with this profession can make some changes, modifications and equivalent changes made by using the technical content disclosed above without departing from the spirit and scope of the present invention, which are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of the technical solution of the present invention.
