Description

Technical Field

[0001] The utility model relates to the technical field of building construction connection, in particular to a purlin fixed connection structure. Background Art

[0002] The purlin fixed connection structure is a structure used to fix and connect purlins (i.e. supporting beams). It is commonly found in the fields of construction and carpentry. The common purlin fixed connection structure uses bolts, nuts and washers to connect the purlins to other structures (such as columns and walls). This connection structure can usually provide a stable support and connection effect, ensuring that the purlins can safely and stably support the structure when bearing loads.

[0003] Existing conventional fixed brackets can be installed and fixed on flat ground in two ways: by purlin supports and by directly fixing the inner side of the purlin to the inclined beam, thereby improving the stability of the bracket. However, since this method is greatly affected by the terrain, it can only be used in areas with relatively flat terrain. When installed on mountainous ground, since the lower end surface of the purlin cannot be completely and tightly fitted with the upper end surface of the inclined beam, the fixing bolts inside the purlin cannot be used, and the bracket can only be fixed and installed by the purlin support alone. In this method, since only the bottom of the purlin support is connected to the inclined beam, and the side of the purlin support is connected to the side of the purlin, the purlin is easily lifted up from the open side when it is sucked by wind, thereby endangering the overall stability of the bracket.

[0004] In view of this, and in response to this technical problem, the present application proposes a purlin fixed connection structure. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a purlin fixed connection structure is proposed, which adopts a Z-shaped purlin support, and utilizes its cross-sectional characteristics to strengthen the fixing method of the fixed bracket purlin, and utilizes the upper and lower bent edges of the purlin to clamp the Z-shaped purlin support. The lower end surface of the Z-shaped purlin support is fixed to the inclined beam, which can effectively prevent the possibility of the purlin being lifted by the wind. This structure is applicable to various terrains such as flat land and mountainous areas. The force of the purlin is changed from the previous lower end surface force to the upper and lower end surfaces being jointly forced, thereby enhancing the stability of the structure.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A purlin fixed connection structure comprises an inclined beam, a purlin body is arranged at the top of the inclined beam, a Z-shaped purlin support is arranged on the upper side of the inner wall of the purlin body, an L-shaped purlin support is arranged at the right end of the purlin body, the Z-shaped purlin support and the inner wall of the L-shaped purlin support are both detachably connected with a second purlin support support tube, the Z-shaped purlin support and the L-shaped purlin support are detachably connected with a first purlin support support tube at one opposite end, and a plurality of bar holes are opened on the right side of the inner wall of the purlin body.

[0008] Furthermore, the bottom end of the Z-shaped purlin support is arranged on the left side of the top end of the inclined beam.

[0009] Furthermore, the bottom end of the L-shaped purlin support is arranged on the right side of the top end of the inclined beam.

[0010] Furthermore, the outer walls of the second purlin support tubes are connected to the bottoms of the Z-shaped purlin support and the L-shaped purlin support corresponding to the inner walls of the inclined beams through bolts.

[0011] Furthermore, the top end of the Z-shaped purlin support is in close contact with the upper side of the inner wall of the purlin body.

[0012] Furthermore, the outer wall of the first purlin supporting tube is arranged on the inner wall of the strip hole.

[0013] Furthermore, the purlin body is a purlin with upper and lower bending edges of unequal lengths, and the lower end surface of the purlin body is narrower than the upper end surface.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, through the coordination among the oblique beam, the purlin body, the Z-shaped purlin support, the L-shaped purlin support and the strip hole, the Z-shaped purlin support is adopted, and its cross-sectional characteristics are utilized to strengthen the fixing method of the fixed bracket purlin, and the upper and lower bent edges of the purlin are utilized to clamp the Z-shaped purlin support, and the lower end surface of the Z-shaped purlin support is fixed to the oblique beam, which can effectively prevent the possibility of the purlin being lifted by the wind. This structure is applicable to various terrains such as flat land and mountainous land. The force of the purlin is changed from the previous lower end surface force to the upper and lower end surfaces being jointly forced, thereby enhancing the stability of the structure.

[0016] 2. In the present invention, by cooperating between the first purlin support support tube and the second purlin support support tube, a support tube is added between the front and rear purlin supports, which can effectively prevent the deformation of related components when the purlin support bolts are tightened.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-3 The utility model provides an embodiment: a purlin fixed connection structure, including an inclined beam 1, a purlin body 2 is arranged at the top of the inclined beam 1, a Z-shaped purlin support 3 is arranged on the upper side of the inner wall of the purlin body 2, an L-shaped purlin support 4 is arranged at the right end of the purlin body 2, the inner walls of the Z-shaped purlin support 3 and the L-shaped purlin support 4 are both detachably connected with a second purlin support support tube 6, the opposite ends of the Z-shaped purlin support 3 and the L-shaped purlin support 4 are detachably connected with a first purlin support support tube 5, and a plurality of strip holes 7 are opened on the right side of the inner wall of the purlin body 2.

[0024] Specifically, the purlin body 2 is placed vertically above the inclined beam 1, and the side of the purlin body 2 is installed and fixed back to back with the L-shaped purlin bracket 4, and the other right-angled side of the L-shaped purlin bracket 4 is installed and fixed with the inclined beam 1 by bolts, and one side of the bent edge of the Z-shaped purlin bracket 3 is inserted into the inner side of the purlin body 2, and the upper end of the vertical edge is on the inner side of the opening side of the purlin body 2, and the lower end is on the outer side of the opening side of the purlin body 2. The lower end face of the Z-shaped purlin bracket 3 is fixed and installed with the inclined beam 1 by bolts, and can be used on flat ground and mountainous areas. The strip holes 7 on the vertical sides of the Z-shaped purlin bracket 4 and the Z-shaped purlin bracket 3 can achieve the purpose of adjustment. The upper end surface of the Z-shaped purlin bracket 3 is against the inner upper end surface of the opening side of the purlin body 2. When the purlin body 2 is subjected to downward pressure, it can assist in bearing a part of the load borne by the purlin bracket. When the purlin body 2 is subjected to wind suction load, since the front and rear sides of the purlin body 2 are fixed to the inclined beam 1 by bolts through the purlin bracket, the purlin body 2 will not be lifted up due to the unfixed opening side when it is subjected to wind suction.

[0025] The bottom end of the Z-shaped purlin support 3 is arranged on the left side of the top end of the inclined beam 1, and the bottom end of the L-shaped purlin support 4 is arranged on the right side of the top end of the inclined beam 1. The outer wall of the second purlin support support tube 6 is respectively connected to the bottom of the Z-shaped purlin support 3 and the L-shaped purlin support 4 corresponding to the inner wall of the inclined beam 1 by bolts. The top of the Z-shaped purlin support 3 is in close contact with the upper side of the inner wall of the purlin body 2. The outer wall of the first purlin support support tube 5 is arranged on the inner wall of the bar hole 7. The purlin body 2 is a purlin with unequal lengths of upper and lower bending edges, and the lower end surface of the purlin body 2 is narrower than the upper end surface.

[0026] Specifically, the purlin body 2 is fixed at the front and rear to enhance its overall stability under various working conditions, and a first purlin support pipe 5 is added between the front and rear purlin supports to prevent the pulling deformation caused by tightening the bolts.

[0027] Working principle: the purlin body 2 is placed vertically above the inclined beam 1, the side of the purlin body 2 is installed and fixed back to back with the L-shaped purlin bracket 4, and the other right-angled side of the L-shaped purlin bracket 4 is installed and fixed with the inclined beam 1 by bolts. The purlin body 2 is a purlin with unequal lengths of upper and lower bent edges, and the lower end face is narrower than the upper end face. One side of the bent edge of the Z-shaped purlin bracket 3 is inserted into the inner side of the purlin body 2, the upper end of the vertical edge is on the inner side of the opening side of the purlin body 2, and the lower end is on the outer side of the opening side of the purlin body 2. The lower end face of the Z-shaped purlin bracket 3 is fixed with the inclined beam 1 by bolts. During installation, holes are opened on the vertical edges of the L-shaped purlin support 4 and the Z-shaped purlin support 3, and the first purlin support support tube 5 is placed between the open side of the purlin body 2 and the Z-shaped purlin support 3. Bolts are passed through the L-shaped purlin support 4, the purlin body 2, the first purlin support support tube 5, and the Z-shaped purlin support 3 from the front end and then clamped and fixed. The lower end surfaces of the L-shaped purlin support 4 and the Z-shaped purlin support 3 are tightly attached to the inclined beam 1. A second purlin support support tube 6 is also needed inside the inclined beam 1 to support the two ends of the open section of the inclined beam 1, fixing it into a closed section and increasing the overall stability of the section.
