Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] The top formwork construction process includes the following steps: Step 1. Before construction, basic preparation work needs to be carried out, including formulating a top formwork construction plan, purchasing materials and equipment required for construction, and forming a professional construction team; Step 2. During the top formwork construction process, a frame structure needs to be installed to support the construction work; the installation of the frame needs to be carried out according to the construction plan and standards to ensure that it can withstand the required weight and pressure; Step 3. Pouring concrete. Pouring concrete is a key step in top formwork construction. It is necessary to pour concrete into the formwork according to the requirements of the construction plan to ensure density and uniformity. Step 4. Install the gray board and reinforcement ribs. After the top formwork is constructed, the gray board and reinforcement ribs need to be installed.

After the construction is completed, acceptance and maintenance are required; acceptance includes inspection of the quality and safety performance of the structure, and maintenance is carried out according to the characteristics and usage of the building materials.

[0043] The frame beam template usually used in step two includes a template on the side of the body and a template on the top. The top template is provided with a through hole for inserting a vibrating rod. However, after this frame beam template is used in step three, it affects the movement of the vibrating rod, making it inconvenient to vibrate the concrete, resulting in uneven concrete and affecting its quality.

[0044] The embodiments of the present application provide a frame beam template for top form construction and a frame beam top formless construction method to solve the problem in the related art that the frame beam template affects the movement of the vibrating rod, making it inconvenient to vibrate the concrete and resulting in uneven concrete.

[0045] See also Figure 1 , a frame beam formwork for top form construction, comprising:

[0046] Four vertical plates 1, which enclose to form a cylindrical structure;

[0047] A first limiting component 2, which is arranged around the cylindrical structure and connected to the cylindrical structure;

[0048] The second limiting component 3 has a device passage opening and is installed on the top of the first limiting component 2; the projection of the passage opening on the plane where the top end of the cylindrical structure is located covers the cylindrical opening of the cylindrical structure.

[0049] Since the top plate of the traditional frame beam formwork is eliminated and the first limit assembly 2 and the second limit assembly 3 are used to ensure the overall structural strength of the frame beam formwork, the equipment channel opening covers the tube opening of the cylindrical structure during the vibration process, so that the vibrating device can move arbitrarily in the tube opening of the cylindrical structure, thereby making the vibration uniform and improving the quality; furthermore, the equipment channel opening is also convenient for concrete unloading, thereby improving construction efficiency.

[0050] The frame beam is constructed without top formwork, which is convenient for concrete feeding, concrete vibration and high construction efficiency. It has strong applicability, simple and fast construction operation and high construction efficiency. Figure 1 Mark A in the middle, the area where the vibrator can move is Figure 2 As shown in the mark B.

[0051] In some preferred embodiments, in order to ensure the overall structural strength of the frame beam template after the top template is removed and to facilitate disassembly after the construction is completed, the following settings are provided:

[0052] The first structural form:

[0053] The first limiting assembly 2 includes four vertical rods 200, which are distributed in a rectangular shape;

[0054] The second limiting assembly 3 includes four first transverse rods 300 , and one first transverse rod 300 is arranged between two adjacent vertical rods 200 ;

[0055] Both ends of the first transverse rod 300 are connected to the vertical rod 200 via first detachable connecting pieces.

[0056] The vertical rod 200 is provided with a transverse through hole;

[0057] The first detachable connecting member includes screw rods arranged at both ends of the first transverse rod 300 . The screw rods penetrate corresponding transverse through holes and are threadedly connected with locking nuts.

[0058] To enhance the stability of the structure, the first limit assembly 2 further includes a second transverse rod, and a second transverse rod is arranged between two adjacent vertical rods 200 and is located below the first transverse rod 300. The second transverse rod is also detachably connected via a first detachable connector.

[0059] The second structural form:

[0060] The four vertical plates 1 are divided into two groups; the two vertical plates 1 in each group are vertically connected to each other to form an L-shaped structure; the two L-shaped structures form a cylindrical structure. This form facilitates the enclosure connection of the vertical plates 1.

[0061] The first limiting assembly 2 includes four vertical rods 200, which are distributed in a rectangular shape;

[0062] The second limiting assembly 3 includes four first transverse rods 300 , and one first transverse rod 300 is arranged between two adjacent vertical rods 200 ;

[0063] Both ends of the first transverse rod 300 are connected to the vertical rod 200 via first detachable connecting pieces.

[0064] In the second structural form, the structural forms of the first limiting assembly 2 and the second limiting assembly 3 are substantially the same as those of the first structural form.

[0065] The third structural form, refer to the attached Figure 2-4 ;

[0066] In order to reduce structure, cut costs, and increase efficiency, the following settings are available:

[0067] The first limiting assembly 2 includes four vertical rods 200, which are distributed in a rectangular shape; in two relatively parallel vertical surfaces of the two L-shaped structures, each vertical surface is fixedly connected to two vertical rods 200;

[0068] The second limiting assembly 3 includes two first transverse rods 300 located between the two vertical planes, one end of the first transverse rod 300 is connected to the vertical rod 200 of one of the two relatively parallel vertical planes through a second detachable connecting piece, and the other end is connected to the vertical rod 200 of the other of the two relatively parallel vertical planes through a second detachable connecting piece.

[0069] The vertical rod 200 is provided with a transverse through hole;

[0070] Both ends of the first transverse rod 300 extend into corresponding transverse through holes, and the first transverse rod 300 is also provided with vertical through holes;

[0071] The top surface of the L-shaped structure is provided with a vertical socket;

[0072] The second detachable connecting member comprises a limiting pin rod 5 , and a vertical through hole and a vertical insertion hole are sequentially formed at the bottom end of the limiting pin rod 5 to connect the first transverse rod 300 and the L-shaped structure.

[0073] In this structure, after the two ends of the first transverse rod 300 are inserted into the corresponding transverse through holes and the vertical through holes and the vertical sockets are aligned, the connection can be completed by directly inserting the limit pin rod 5. After the construction is completed, the limit pin rod 5 can be directly pulled out, and then the first transverse rod 300 can be removed.

[0074] In addition, since each of the two relatively parallel vertical surfaces on the two L-shaped structures is fixedly connected to two vertical rods 200, the installation and positioning of the vertical rods 200 are reduced, the construction steps are reduced, and the construction efficiency is improved.

[0075] The above three structural forms are selected according to the needs, and the best one is the third structural form.

[0076] In some preferred embodiments, the frame beam template for top form construction further includes a square steel tube 4, which is arranged along the length direction of the frame beam template and is detachably connected to the bottom of the first transverse rod 300. The square steel tube 4 facilitates the formation of a groove on the top of the frame beam, and does not need to be opened later.

[0077] The present application also proposes a frame beam top formwork-free construction method, which comprises the following steps:

[0078] Step 100, providing a frame beam template for top form construction, and assembling and setting it in the construction area;

[0079] Step 101, after pouring concrete into the frame beam formwork for top form construction, extend the vibrating device into the cylindrical structure from the opening of the equipment channel, and then vibrate.

[0080] Since the top plate of the traditional frame beam formwork is eliminated and the first limit assembly 2 and the second limit assembly 3 are used to ensure the overall structural strength of the frame beam formwork, the equipment channel opening covers the tube opening of the cylindrical structure during the vibration process, so that the vibrating device can move arbitrarily in the tube opening of the cylindrical structure, thereby making the vibration uniform and improving the quality; furthermore, the equipment channel opening is also convenient for concrete unloading, thereby improving construction efficiency.

[0081] That is to say, when the frame beam is constructed without a top formwork, it is convenient for concrete unloading, concrete vibration and high construction efficiency; it has strong applicability, simple and fast construction operation and high construction efficiency.
