Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a combined structure of window sill capping beams for masonry walls. Background Technology

[0002] Currently, there are three main construction methods for traditional window opening capping beams: 1. When the masonry reaches the designed height of the window opening, formwork is erected and the capping beam concrete is poured. After the strength reaches the design requirements, masonry continues upwards. This method increases the intervals between masonry construction, easily leading to wasted construction time. 2. After the masonry reaches the designed height of the window opening, a precast capping beam is placed, and then masonry continues upwards. This method helps shorten the construction period, but because the dimensions of the precast lintel are fixed, construction flexibility is poor, and it is impossible to adjust according to the actual site conditions. Furthermore, when the distance between the window opening and the concrete structure is less than the support length required by the capping beam specification, the precast capping beam cannot be effectively connected to the primary structure. This results in the capping beam being unable to transfer the vertical load on the edge of the opening to the concrete structure on the side of the opening. Under long-term load, stress concentration may lead to the formation of "inverted V" cracks. Thirdly, leaving a groove in the capping beam area during the masonry construction process and then pouring the capping beam concrete after the masonry construction is completed is a reversed process, which reduces the structural stability and increases the risk of leakage. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a combined structure for window sill capping beams for masonry walls, which combines cast-in-place capping beams with precast capping beams, thus saving construction time and ensuring structural stability.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is a combined structure for window sill capping beams in masonry walls, comprising:

[0005] Two precast sections are located at both ends of the design position of the capping beam and fixed in the masonry on the corresponding side. The two precast sections extend towards the window opening and extend out of the masonry on both sides.

[0006] A pair of pre-embedded reinforcing bars, one end of which is pre-embedded in one of the two precast sections that are relatively close to each other, and the other end extends out of the corresponding precast section;

[0007] A connecting bar connects the two pre-embedded bars;

[0008] The cast-in-place section is located in the middle of the designed position of the capping beam and connects the two precast sections. The embedded reinforcement and the connecting reinforcement are both cast in the cast-in-place section.

[0009] The further improvement of this utility model for the combined structure of window sill capping beams for masonry walls is that both of the prefabricated sections are right-angled trapezoids, and the inclined surfaces of the two prefabricated sections are formed on the relative inner sides of the two prefabricated sections, and are inclined downwards from the outside to the inside.

[0010] A further improvement of this utility model for the combined structure of window sill capping beams for masonry walls is that each prefabricated segment has a roughened surface on its inclined surface.

[0011] A further improvement of this utility model for the combined structure of window sill capping beams for masonry walls is that the number of pre-embedded reinforcing bars is multiple pairs, and the multiple pairs of pre-embedded reinforcing bars are connected at intervals on the prefabricated section.

[0012] A further improvement of this utility model for the combined structure of window sill capping beams for masonry walls is that the pre-embedded reinforcement extends by a length corresponding to the precast section of not less than 50 times the diameter of the precast reinforcement.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] By dividing the capping beam into precast and cast-in-place sections, the construction of the capping beam can be made more flexible, without taking up construction time or affecting connection stability. Attached Figure Description

[0022] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the combined structure of the window sill capping beam for masonry walls according to this utility model.

[0023] Please see Figures 1-4 A composite structure for window sill capping beams used in masonry walls, including:

[0024] Two prefabricated sections 1 are located at both ends of the design position of the capping beam and fixed in the masonry 4 on the corresponding side. The two prefabricated sections 1 extend towards the window opening and extend out of the masonry 4 on both sides.

[0025] A pair of pre-embedded reinforcing bars 2, one end of which is pre-embedded in the two relatively close ends of the two precast sections 1, and the other end extends out to the corresponding precast section 1;

[0026] Connecting bar 3 connects the two pre-embedded bars 2;

[0027] The cast-in-place section 5 is located in the middle of the design position of the capping beam and connects the two precast sections 1. The embedded reinforcement 2 and the connecting reinforcement 3 are both cast in the cast-in-place section 5.

[0028] By dividing the capping beam into precast section 1 and cast-in-place section 5, the capping beam can be constructed more flexibly without taking up construction time or affecting connection stability.

[0029] Specifically, the two precast sections 1 can be used as irregular masonry. When the masonry 4 is constructed to the design position of the capping beam, the two precast sections 1 are built to the design installation position.

[0030] Specifically, cement mortar is applied between the precast section 1 and the adjacent masonry.

[0031] Preferably, both prefabricated sections 1 are right-angled trapezoids, and the inclined surfaces of the two prefabricated sections 1 are formed on the opposite inner sides of the two prefabricated sections, and are inclined downward from the outside to the inside.

[0032] Specifically, the top of the prefabricated section 1 is the short side of a right trapezoid, and the bottom of the prefabricated section 1 is the long side of a right trapezoid.

[0033] By setting the precast section 1 into a right trapezoid, the connection surface between the cast-in-place section 5 and the precast section 1 is extended, thereby improving the connection stability.

[0034] Preferably, the inclined surface of each precast segment 1 is roughened.

[0035] By roughening the slope of the precast section 1, the connection between the cast-in-place section 5 and the precast section 1 is improved when the cast-in-place section 5 is subsequently cast.

[0036] Preferably, the number of the embedded reinforcing bars 2 is multiple pairs, and multiple pairs of embedded reinforcing bars 2 are connected at intervals on the precast section 1.

[0037] Specifically, there are also multiple connecting bars 3, and one connecting bar 3 is connected between each pair of pre-embedded bars 2.

[0038] By setting multiple pairs of pre-embedded reinforcing bars 2 and multiple connecting reinforcing bars 3, the strength of the cast-in-place section 5 is ensured during the subsequent formwork erection and pouring of the cast-in-place section 5.

[0039] Preferably, the embedded reinforcement 2 extends out by a length corresponding to the precast section 1 by not less than 50 times the diameter of the precast reinforcement.

[0040] Specifically, the embedded reinforcement 2 and the connecting reinforcement 3 overlap each other.

[0041] Limiting the length of the embedded reinforcement 2 provides a connection basis for the connecting reinforcement 3.
