Description

Technical Field

[0001] This application belongs to the field of construction safety protection technology, specifically relating to a safety protection device and structure for the construction of cap beam support pad stones, which is applied to the construction process of cap beam support pad stones for safety protection during the construction of support pad stones. Background Technology

[0002] The primary functions of bridge cap bearing pads are to support bridge bearings, transfer loads, adjust bridge elevation, protect the cap beam structure, and accommodate bridge deformation. They are an indispensable part of the bridge structure, playing a crucial role in the bridge's safety, stability, and durability. During design and construction, the dimensions, strength, and location of the bearing pads must be strictly controlled according to design requirements to ensure the overall performance of the bridge.

[0003] In the past, when constructing the bearing pad of the cap beam, workers relied solely on pre-embedded steel bars or anchor rings on the cap beam to form safety belt attachment points or as fixed ends of safety ropes. The work area was not enclosed, which easily led to materials and tools falling from heights, or personnel falling accidents. Utility Model Content

[0004] The purpose of this application is to provide a safety protection device and structure for the construction of bearing pad stones for cap beams. Using this facility can create an effective, safe, and enclosed construction environment, reduce external interference, and effectively prevent construction workers from accidentally falling when working at heights. This facility greatly improves the safety of the construction of bearing pad stones. At the same time, construction workers can concentrate more on their work under the protection of the device, which also improves work efficiency.

[0005] The objective of this application is achieved through the following technical solution:

[0006] A safety protection device for the construction of cap beam support pad stones includes side fixing frames on the front and rear sides. The side fixing frames on the front and rear sides are formed by connecting horizontal fixing rods and vertical fixing rods.

[0012] Furthermore, a longitudinally adjustable stone limiting rod is connected between the side fixing brackets on the front and rear sides.

[0013] Furthermore, the longitudinal stone-limiting rods are arranged in pairs.

[0014] Furthermore, the longitudinal stone limiting rods are arranged individually and cooperate with the longitudinal beam supports.

[0015] A safety protection structure for the construction of a cap beam support pad includes a cap beam and the aforementioned safety protection device for the construction of a cap beam support pad.

Detailed Implementation

[0024] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0025] Example 1

[0026] refer to Figure 1 , Figure 2 and Figure 3 As shown, a safety protection device for the construction of cap beam support pad stones includes side fixing frames on the front and rear sides, end fixing frames on the left and right ends, longitudinal fixing rods 2, longitudinal beam support rods 4, longitudinal stone limiting rods 5, dense protective netting 6, and guy ropes 7.

[0027] The side fixing frames on the front and rear sides are formed by connecting several horizontal fixing rods 1 and several vertical fixing rods 3. The horizontal and vertical fixing rods form the skeleton of the protective side, which is used to support the load-bearing structure. Each of the front and rear side fixing frames is equipped with a dense protective net 6, which serves as the working surface of the protective side and, together with the skeleton, forms a protective function. When the device is in place, the front and rear side fixing frames also form a front-to-back limiting and locking relationship with the cover beam 8.

[0028] Several longitudinal fixing rods 2 are connected between the middle and upper parts of the side fixing frames on the front and rear sides. The longitudinal fixing rods 2 above the middle leave space for the lower part to cooperate with the cover beam 8. The longitudinal fixing rods 2 connect the side fixing frames on the front and rear sides into a whole, realizing the overall installation and hoisting, as well as the overall stress support, and at the same time, the overall enclosure and protection.

[0029] Several longitudinal beam supports 4 are connected between the middle of the side fixing frames on the front and rear sides. The longitudinal beam supports 4 are also used to connect the side fixing frames on the front and rear sides into a whole. At the same time, the longitudinal beam supports 4 also have the function of supporting. When the device is in place, the upper surface of the cover beam 8 supports the longitudinal beam supports 4 to achieve the specific support function.

[0030] The end face fixing frames on the left and right ends are formed by connecting several longitudinal fixing rods 2, several vertical fixing rods 3, and several longitudinal beam supports 4. The longitudinal and vertical fixing rods and the longitudinal beam supports form the skeleton of the protective end face, which is used to support the load-bearing force. The side fixing frames on the left and right ends are equipped with dense mesh protective netting 6. The dense mesh protective netting 6 serves as the working surface of the protective end face and together with the skeleton, it forms a protective function.

[0031] The side fixing frames on both the front and rear sides are equipped with guy ropes 7. The guy ropes 7 can be anchored to the ground and provide front and rear tension to the side fixing frames from both sides, which can further improve the stability of the side fixing frames and prevent the entire device from tipping over.

[0032] The side mounting brackets have a rectangular outline structure, which facilitates the connection and installation of the mounting rods, thus forming a rectangular protective surface on the front and rear sides. The end mounting brackets have a U-shaped outline structure, which also facilitates the connection and installation of the mounting rods and beam supports, while forming an upper protective and lower support structure on the left and right end faces.

[0033] The connections between any two members in the transverse fixing rod 1, longitudinal fixing rod 2, vertical fixing rod 3, and longitudinal beam support rod 4 are all welded connections. All members are made of square tubular steel. The members are first welded on site to assemble them into a whole structure, or they can be assembled by bolting.

[0034] The dense mesh protective netting is made of brand-new high-density polyethylene monofilament. It is connected to the poles on each protective surface using a binding method, achieving an integrated function between the poles and the netting. Since the lower part of the side fixing frames on the front and rear sides is used for locking and limiting, the dense mesh protective netting can be placed only in the upper part of the side fixing frames, avoiding material waste.

[0035] The transverse fixing rod 1 includes a top transverse rod 101, a middle upper transverse rod 102, a middle transverse rod 103, and a bottom transverse rod 104. The longitudinal fixing rod 2 includes a top longitudinal rod 201 and a middle upper longitudinal rod 202 located at the end. The vertical fixing rod 3 includes an end vertical rod 301 and a middle vertical rod 302.

[0036] The two ends of each member of the transverse fixing rod 1 are connected to the end vertical rods 301, and the middle of each member of the transverse fixing rod 1 is connected to several middle vertical rods 302 to form a rectangular outline structure of the side fixing frame.

[0037] Several top longitudinal bars 201 arranged in the transverse direction are connected between the top transverse bars 101 on both sides. Middle upper transverse bars 102 on both sides are connected with middle upper longitudinal bars 202 located at both ends. Several longitudinal beam supports 4 arranged in the transverse direction are connected between the middle transverse bars 103 on both sides. The top transverse bars 101, middle upper transverse bars 102, longitudinal beam supports 4 and end vertical bars 301 at the ends together form a portal-shaped outline structure of the end face fixing frame.

[0038] A horizontally adjustable longitudinal stone limiting rod 5 is connected between the side fixing brackets on the front and rear sides. The longitudinal stone limiting rod is used to lock the pad stone. Since the longitudinal stone limiting rod 5 is fixed on the overall device, it realizes the lateral limiting function of the entire device, avoiding the slippage and displacement of the device, which would cause the problem of unstable protection.

[0039] By adjusting the lateral position of the longitudinal stone restraint rods 5, it is possible to accommodate different sizes of pad stones in different positions. The longitudinal stone restraint rods 5 are arranged in pairs, that is, a pair of longitudinal stone restraint rods 5 are used to hold a pad stone in place from left to right. Similarly, in conjunction with the longitudinal beam support rods 4, the longitudinal stone restraint rods 5 can also be used individually.

[0040] This device is used in conjunction with at least two unit modules. The fixing rods of two adjacent safety protection devices are connected by bolts to achieve the assembly connection of the two devices. When organizing the construction of the support pad stone, at least two unit modules connected together to form a safety protection device are used, and each safety protection device is connected and fixed to the external guy ropes at the front and rear.

[0041] Example 2

[0042] refer to Figure 1 , Figure 2 and Figure 3 As shown, a safety protection structure for the construction of cap beam support pad stones includes a cap beam 8, and also includes the safety protection device for the construction of cap beam support pad stones as described in Embodiment 1.

[0043] The side fixing brackets on the front and rear sides are located on the front and rear sides of the cap beam 8, respectively. The lower middle part of the side fixing bracket serves as a limiting and fitting surface, while the upper middle part serves as a protective surface. Longitudinal beam support rods 4 are installed on the upper surface of the cap beam 8 to support and mount the device. The side fixing brackets on the front and rear sides are connected to the ground via guy ropes 7 to improve the stability of the device.

[0044] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
