Description

Technical Field

[0001] The utility model relates to the technical field of connection structural members, in particular to a connection structural member for plastic-steel doors and windows. Background Technique

[0002] At present, most plastic-steel windows use welding to connect all window sashes together. Due to the nature of the PVC material itself, when the seasons alternate between spring and winter, due to low-temperature brittleness and thermal expansion and contraction, cracks appear at the welded positions, resulting in a decrease in the strength of the windows and a reduction in their performance. The cracked positions are mainly concentrated at the welded positions of the frame and the stile, which is also the location where the stress of the entire door and window is concentrated. To avoid the cracking of the welded corners, we propose a connection structural member for plastic-steel doors and windows. Content of the Utility Model

[0003] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a connection structural member for plastic-steel doors and windows is proposed.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

The concave member includes two side portions and a horizontal portion. Positioning holes and second connection holes are provided on both of the two side portions. An intermediate block is provided between the two side portions. Extrusion grooves are provided on two opposite sides of the intermediate block, and positioning members are provided in the extrusion grooves. The positioning members include a displacement block and a clamping block connected together.

[0006] Preferably, a through hole is provided on the gasket, and the gasket can be movably sleeved on the connection bolt through the through hole. A first connection hole is provided on the horizontal portion, and the connection bolt passes through the through hole and is screwed into the first connection hole.

[0007] Preferably, the concave member is formed by stamping. The two side portions are respectively located on both sides of the horizontal portion relatively.

A through hole 2 is provided on the gasket 1. The gasket 1 can be movably sleeved on the connecting bolt 7 through the through hole 2. A first connecting hole 311 is provided on the horizontal portion 31. The connecting bolt 7 passes through the through hole 2 and is screwed into the first connecting hole 311. The concave member 3 is formed by stamping. The two side portions 32 are respectively located on both sides of the horizontal portion 31 relatively. The positioning holes 321 and the second connecting holes 322 on the two side portions 32 correspond to each other. The concave member 3 can also be connected to the longitudinal window sash profile through the second connecting holes 322 and screws. Specifically, the concave member 3 is placed at the bottom of the longitudinal window sash profile, and the screws pass through the holes pre-drilled on the longitudinal window sash profile and are screwed into the second connecting holes 322 to realize the connection between the concave member 3 and the longitudinal window sash profile;

[0025] Then, put the gasket 1 on the connecting bolt 7 through the perforation 2. Then, place the bottom of the longitudinal window sash profile on the transverse window sash profile, and pass the connecting bolt 7 through the pre-drilled hole in the transverse window sash profile, and connect it to the second connecting hole 322 in a threaded connection manner. Continue to turn it, so that the connecting bolt 7 tightens the transverse window sash profile against the longitudinal window sash profile through the gasket 1 at the bottom of the transverse window sash profile, realizing the connection between the transverse window sash profile and the longitudinal window sash profile.

[0026] Embodiment Two

[0027] Refer to Figures 1-4 , a connecting structural member for a plastic-steel door and window, including a gasket 1, a connecting bolt 7 and a concave member 3 that make up the connecting structural member. The concave member 3 includes two side parts 32 and a horizontal part 31. Positioning holes 321 and second connecting holes 322 are opened on both side parts 32. An intermediate block 4 is provided between the two side parts 32. Extrusion grooves 41 are opened on two opposite sides of the intermediate block 4. Positioning members 5 are provided in the extrusion grooves 41. The positioning member 5 includes a displacement block 51 and a clamping block 52 connected together. The side surface of the clamping block 52 opposite to the displacement block 51 is an inclined surface. The inclined surface of the clamping block 52 matches the extrusion groove 41. The clamping block 52 is inserted and matched with the positioning hole 321. When the intermediate block 4 squeezes the displacement block 51 through the extrusion groove 41, the displacement block 51 moves horizontally so that the clamping block 52 in the positioning hole 321 is inserted into the pre-opened hole on the longitudinal window sash profile, thereby limiting the connection between the concave member 3 and the longitudinal window sash profile;

[0028] During use, place the intermediate block 4 between the two side parts 32, then place the positioning member 5 in the extrusion groove 41 and insert it into the positioning hole 321. Then, place the concave member 3 in the longitudinal window sash profile. Then, put the gasket 1 on the connecting bolt 7 through the perforation 2. Then, place the bottom of the longitudinal window sash profile on the transverse window sash profile, and pass the connecting bolt 7 through the pre-drilled hole in the transverse window sash profile, and rotate the connecting bolt 7 and thread it into the second connecting hole 322. Continue to turn the connecting bolt 7, so that the connecting bolt 7 abuts against and moves away from the horizontal part 31 of the intermediate block 4. The intermediate block 4 moves to squeeze the two displacement blocks 51 in the two positioning members 5 through the extrusion groove 41, so that the two displacement blocks 51 are attached to the opposite surfaces of the two side parts 32. In this way, the clamping block 52 is inserted into the positioning hole 321 and extends into the pre-drilled hole on the longitudinal window sash profile, thereby realizing the connection between the concave member 3 and the longitudinal window sash profile. At the same time, the connecting bolt 7 will also tighten the transverse window sash profile through the gasket 1 at the bottom of the transverse window sash profile, keeping it stably located at the bottom of the longitudinal window sash profile, and further realizing the connection between the transverse window sash profile and the longitudinal window sash profile.
