Abstract
Description
Technical Field
[0001] This utility model relates to the field of lintel wall technology, specifically a window sill lintel wall structure. Background Technology
[0002] When constructing masonry walls, windows are typically reserved for later window installation. Windows serve as a connection between the interior and exterior. Windows generally include a windowsill. During windowsill construction, a lintel is required at the top of the windowsill, and a capping beam is required at the bottom. This means that formwork must be erected and concrete poured in the areas where the lintel and capping beams are located. Subsequent masonry work can only proceed after the concrete has reached the required strength. This construction method requires a considerable amount of time to pour the capping beam, and the structure and strength are unstable. To address these issues, an innovative design is proposed based on the existing lintel-masonry wall structure. Utility Model Content
[0003] The purpose of this utility model is to provide a masonry wall structure for window sill lintels to solve the technical problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a window sill lintel masonry wall structure, including a base wall, side walls spaced above the base wall, a precast top beam between the base wall and the corresponding side walls, a structural beam at the end of the side wall away from the precast top beam, connecting bars extending outwards inside the precast top beam, and connecting bars on both sides extending between the precast top beams on both sides, side templates on the inner and outer sides of the precast top beam, clamping rods above the side templates, clamping plates at both ends of the clamping rods, and limit nuts on the outer side of the clamping plates.
[0005] Preferably, one end of the precast pressure beam protrudes from the transverse side surface of the side wall.
[0006] Preferably, one end of the connecting bar is cast into the precast capping beam, and the other end of the connecting bar protrudes out of the precast capping beam, and the connecting bars are evenly distributed on the precast capping beam.
[0007] Preferably, the side templates are distributed on the front and rear surfaces of the bottom wall, and the two side templates and the two precast top beams form a rectangular groove.
[0008] Preferably, the clamping rods are symmetrically distributed about the longitudinal centerline of the side template, the surface of the clamping rods is provided with threads, and the limiting nuts are connected to the clamping rods at both ends by threads.
[0009] Preferably, the clamping plate and the clamping rod are connected by a through sliding connection, and the clamping plate is provided in two sets, with each set of clamping plates respectively located at both ends of a single clamping rod.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This window sill lintel masonry structure, by setting a precast top beam between the bottom wall and the side wall, and setting side formwork at the front and back of the bottom wall, allows the process of pouring concrete between the connecting bars and the precast top beam to be carried out between the side walls, without affecting the masonry of the side walls, which helps to save construction time. The precast top beam after the concrete is poured can still provide strong connection stability between the bottom wall and the side wall, thereby improving the stability of the window sill.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-3 This utility model provides a technical solution: a window sill lintel wall structure, including a bottom wall 1, characterized in that: side walls 2 are provided at intervals above the bottom wall 1, a precast top beam 3 is provided between the bottom wall 1 and the corresponding side wall 2, a structural beam 4 is provided at the end of the side wall 2 away from the precast top beam 3, a connecting bar 5 is provided inside the precast top beam 3 and extends outward, and the connecting bars 5 on both sides extend to the space between the precast top beams 3 on both sides, side templates 6 are provided on the inner and outer sides of the precast top beam 3, a clamping rod 7 is provided above the side template 6, clamping plates 8 are provided at both ends of the clamping rod 7, and limit nuts 9 are provided on the outer side of the clamping plates 8.
[0017] In one or more embodiments of this utility model, one end of the precast top beam 3 protrudes from the transverse side surface of the side wall 2, which facilitates the subsequent pouring of the window sill lintel and avoids affecting the masonry of the side wall 2.
[0018] In one or more embodiments of this utility model, one end of the connecting bar 5 is cast into the precast top beam 3, and the other end of the connecting bar 5 protrudes out of the precast top beam 3. The connecting bars 5 are evenly distributed on the precast top beam 3. The setting of the connecting bars 5 improves the stability of the subsequent casting of the window sill lintel and improves the compressive strength.
[0019] In one or more embodiments of this utility model, the side templates 6 are distributed on the front and rear surfaces of the bottom wall 1. The two side templates 6 and the two precast top beams 3 form a rectangular groove, which is beneficial for casting the lintel in the rectangular groove enclosed by the side templates 6 and the precast top beams 3.
[0020] In one or more embodiments of this utility model, the clamping rods 7 are symmetrically distributed about the longitudinal centerline of the side template 6. The surface of the clamping rods 7 is provided with threads. The limiting nuts 9 are connected to the clamping rods 7 at both ends by threads. The clamping plates 8 are connected to the clamping rods 7 by a through sliding connection. There are two sets of clamping plates 8. Each set of clamping plates 8 is respectively provided at both ends of a single clamping rod 7. When the limiting nuts 9 are turned, the limiting nuts 9 will be displaced on the clamping rods 7 through threads, so that the limiting nuts 9 press against the clamping plates 8 and stably clamp the front and rear surfaces of the bottom wall 1.
[0021] according to Figures 1-3 As shown, firstly, the precast top beam 3 is built between the bottom wall 1 and the side wall 2. Then, the side formwork 6 is attached to the front and rear surfaces of the bottom wall 1. The clamping rod 7 is passed through the side formwork 6. Next, the limiting nut 9 is tightened on the clamping rod 7. At this time, the limiting nut 9 will push the clamping plate 8 to move on the clamping rod 7, so that the limiting nut 9 presses against the clamping plate 8, and then presses against the side formwork 6 to stably clamp it on the front and rear surfaces of the bottom wall 1. This allows the process of pouring concrete between the side formwork 6 on the front and rear sides and the precast top beam 3 on the left and right sides to be carried out between the side walls 2, without affecting the construction of the side walls 2, which helps to save construction time. After the precast top beam 3 is poured with concrete, it can still provide a strong connection stability between the bottom wall 1 and the side wall 2, thereby improving the stability of the windowsill.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
